Description
CA 0211~403 1998-01-29 ELECTRICAL CONNECTOR WITH ZIF SOCKET
BACKGROUND OF THE INVENTION
This invention relates to an electrical connector, more particularly, to an electrical connector with zero insert force (ZIF) socket. When the sliding support is moved traverse, the pins of the Pin Grid Arrays (PGA) 5 packages can be received and retained by the specially designed terminal connecting end to facilitate an easily mounting and excellent conductivity as well as durability.
The PGA socket features an easy removal and mounting of the PGA packages inserted thereof. By this arrangement, the user can complete the replacement of the PGA packages by himself without applying any special tools. Besides, the replacement of the PGA can be easily done by a user, but not a technician.
In light of this, the ZIF socket is more convenient and useful than the low insert force (LIF). The ZIF
socket has been described at many publications, such U.S. Patents No. 4,498,725, 4,988,310; Japanese Patents No. 1-47430, 2-197017; and ROC patent applications No. 80-2-08893, 81-1-104728. Although those socket disclosed in said patents can achieve their own objects, there are still some shortcomings.
As shown in Figures 9A-9C and 10A-lOC, the typical structure of the ZIF socket, the pin socket 1 has a contacting portion 11 at the upper end. The contacting portion 11 defines an inclined elastic body. The pin socket 1 is fixed to the socket body 2. A sliding housing 3 is disposed at the socket 2. The pins 41 of the PGA
packages 4 are first inserted through the holes 31 of the sliding housing 3, and then engage into the housing 2.
As shown in Figure 1 OA, the pin 41 has not been received and engaged with the contacting portion 11 of the pin socket 1. As shown in Figure 1 OB, when the sliding housing 3 is moved traverse, the pin 41 moves to the right accu.dill~,ly to engage with the conductive end 1 la of the contacting portion 11. As shown in Figure 10C, when the pin 41 is pushed toward the conductive end 1 la, the inclined surface 1 lb of the contacting portion 11 will make the conductive end 1 la to open, then the pin 41 and the conductive end 1 la will construct an electrical conductivity.
But the conventional structure can be concluded with the following defects:
1. The pin 41 contacts the conductive end 1 la only at one side, hence this arrangement can not form a tight contact thereof. A poor electrical conductivity may occur thereof.

CA 0211~403 1998-01-29 DETAILED DESCRIPTION OF THE INVENTION
Referring to Figures 1 and 2, the electrical connector made according to this invention comprises a socket body 2. The socket body 2 has a plurality rows of slots 21 at the upper portion for receiving the socket pin 5, not shown in Figure 2. A retaining block 22 and positioning block 23 are disposed at side portion. A
5 recessed portion 24 is disposed at the front portion. A projected portion 25 is disposed at both sides of the recessed portion 24. A hole 251 is defined at both sides of the projected portion 25. An ~ct~ ting level 6 defines an actuating portion 61 thereunder. A lug 62 is defined thereof. A post 621 is disposed at said lug 62.
Said post 621 is pivoted to the hole 251 of the projected portion 25. An actuating arm 63 is connected to one side of the actuating portion 61. A groove 631 is defined at the middle portion of the ~ç~l~ting arm 61 which 10 can be positioned to the retaining block 22 of the socket body 2. A sliding support 3 defines a plurality of holes 31 with respect to the slot 21 of the socket body 2. By this arrangement, the pins 41 of the PGA packages 4 can be received by the holes 31. A retaining slot 32 which can engage with the upper portion of the ~tll~ting portion 61 is disposed at the front lower end of the sliding support 3. A cutout 33 is provided at side for the movement of the sliding support 3. The sliding support 3 further includes a hook 34 projected inward and the hook 34 can engage with a notch 26 located at the underside of the socket body 2. By the rotation of the ~c.~ tin~ lever 6, the sliding support 3 is moved on the socket body 2. Since the configuration of the PGA
packages is known by the skilled in the art, and is not the subject matter of the present invention, no further description is given accordingly.
Referring to Figure 3, the pin socket 5 made according to this invention is formed directly from punching a metal sheet. After pin socket 5 is punched, a first supporting arm 52 and a second supporting arm 53 are defined thereof. The first supporting arm 52 is longer than the second supporting arm 53. The first su~u~ Lillg arm 52 and the second SU1~lJUI lillg arm 53 further are formed a first contacting end 54 and a second contacting end 55 respectively at their upper portion. The first contacting end 54 and the second contacting end 55 are intersected with each other. An actuating tab 542 which is illt~l~;umlected with the metal sheet is defined at the first cûnt~rting end 54. A retaining portion 56 is formed at the lower end of the first contacting end 54 and the second cu.,~ i.,g end 55. A leg 57 is defined at the lower portion of the retaining portion 56. A flange portion 541 is defined at one side of the first contacting end 54. When a further m~hining plucedu~ is applied to the raw pin socket 5, a finished pin socket 5 is completed, as shown in Figures 4 and 5A-5C.
CA 0211~403 1998-01-29 As shown in Figures 4 and 5A-5C, a first curve portion 52a is formed at the first supporting arm 52 and a second curve portion 53a is formed at the second ~ul~pul ~illg arm 53. The first curve portion 52a is larger than the second curve portion 53a. By this arrangement, the first contacting end 54 and the second contacting end 55 are separated with each other. A first conductive surface 54a and a second conductive surface 54b is defined at the first co.,~ i.,g end 54 and the second contacting end 55 respectively thereof. A flange 541 is projected outward from the first conductive surface 54a and defines a guiding surface 541a. A guiding surface 551a is defined at the front surface of the second conducting surface 55a.
By this arrangement and layout, the pin socket 5 can be punched directly by a single metal sheet, advantageously, two conductive surfaces 54a, 55a are formed to facilitate an excellent electricity conductivity 10 between the pin 41 of the PGA packages 4 and the pin socket 5. The concentrated force and friction force are reduced accordingly.
Referring to Figures 6A and 6B, the pin socket 5 is inserted and disposed into the slot 21 of the socket body 2. The pin 41 of the PGA packages 4 can pass through the hole 31 of the sliding support 3 and then be retained into the slot 21 of the socket body 2. The actuating arm 63 of the actuating lever 6 shown in Figure 6A
15 is in vertical position, an open position. The pin 41 of the PGA packages 4 is still not engaged with the pin socket 5. At this position, the PGA packages 4 can be easily removed from the sliding support 3 or inserted into the sliding support 3. As shown in Figure 6B, when the actuating arm 63 of the actuating lever is rotated ninety (90) degrees and retained by the retaining block 22, the actuating portion 61 is moved forward with the rotating centre. The retaining slot 32 is moved forward accordingly. As a result, the PGA packages 4 is moved as the 20 sliding support 3 moves. At last, the pin 41 of the PGA packages 4 is engaged with the pin socket 5. The engagement of the pin 41 of the PGA packages 4 and the pin socket 5 will be detailed as described at Figures 7A and 7B.
As shown in Figure 7A, the sliding support 3 is in an open position. Then the PGA packages 4 can be put onto the sliding support 3 making the pin 41 inserts into the slot 21 of the socket body 2 through the hole 25 31 of the sliding support 3. When the sliding support 3 moves traverse, the pin 41 of the PGA packages 4 will insert into the opening between the first contacting end 54 and the second contacting end 55. By this arrangement, the pin 41 of the PGA packages meets the guiding surface 541a of the first contacting end 54 firstly. When the pin 41 keeps on moving in, the first contacting end 54 is biased outward. This can be referred CA 0211~403 1998-01-29 as the first stage contacting. Then the pin 41 meets the guiding surface 551 a of the second contacting end 55 when the pin 41 moves to the one third distance of the first contacting end 54. The second contacting end 55 is biased outward as long as the pin 41 moves in. This is referred to as the second contacting stage. When the sliding support 3 is moved to a desired position, the pin 41 of the PGA packages 4 is positioned and engaged 5 with the first conductive surface 54a and the second conductive surface 54b and form an excellent electricity conductivity. Since the engagement of the pin 41 with the first contacting end 54 and the second contacting end 55 is by two-stage contacting, the friction force generated thereof is largely reduced. The concentrated force which makes the pin 41 to bend is avoided accordingly. As a result, the service life of the pin 41 is prolonged.
As shown in Figures 8A and 8B, another embodiment of the pin socket 5 is shown. The pin socket 5 is inserted into a slot 21a of the socket body 2a by side. The slot 21a is specially designed for the pin socket 5. Accordingly, the orientation is rotated ninety (90) degrees. A retaining slot 32a is disposed at the lower portion of the sliding support 3a. The retaining slot 32a can receive an actuating tap 542 of the first contacting end 54. The diameter of the hole 3 la of the sliding support 3a is larger than the outer diameter of the pin 41 of the PGA socket 4, hence a space is provided for the movement of the pin 41. When the PGA packages 4 is still not inserted into the sliding support 3a and socket body 2a, the first contacting end 54 of the pin socket 5 is inclined outward and openly. When the PGA package 4 is inserted into the socket body 2a, by the same movement, the sliding support 3a is moved traverse, accordingly, the first contacting end 54 is moved accordingly. Then the contacting end 54 is in contact with the pin 41. As the sliding supporting 3a is moved continuously, the second contacting end 55 is in contact with the pin 41. When the sliding support 3a is moved a predet~ n~d position, then pin 41 is positioned with the first conductive surface 54a and a second conductive surface 54b. The pin 41 is clamped by the first conductive surface 54a and a second conductive surface 54b.
The invention can be concluded with the following advantages.
1. The pin socket 5 is directly punched from a metal sheet to form a first supporting arm 52 and a second supporting arm 53, wherein the first supporting arm 52 is longer than the second supporting arm 53.
A first curve portion 52a is formed at the first ~U~JpO~ g arm 52 and a second curve portion 53a is formed at the second ~u~.u. Lillg arm 53. Accordingly, the pin 41 has an even contact with the first contacting end 54 and a second contacting end 55. The pin 41 then has a tight contact with the pin socket 5. An excellent electricity is achieved.
211540~
2. A first guiding surface 541a and a second guiding surfaoe SSl a is provided respecfively at the first c~ ing end 54 and the second cont~cting end SS. Then the first cont~cting end 54 and the second C~ ing end SS are biased outward IG~Je~;~ivGly, in two stage. The 1uncG~ tllGd force applied to the pin 41 is reduced advt~ agcuu~l~. As a result, the pin 41 will not bend.
3. A first curve portion 52a is formed at the first su~ulling arm 52 and a second culve portion 53a is formed at the second supporting arm 53. Accoldiilgly, an inserting spaoe (S) is formed thereof, as shown in Figure SB. In light Or this, the lower ponion of the pin 41 is free con~ctinp. wi~h ~he pin socket S. The effective contact focus on the first cont~r~ing end 54 and the second cont:~c~ing end SS. Ilence, the friction force is reduced to the lowest level and the pin 41 will not bend or break off.
4. By the nlOVGIIIGIII of the actuating lever 6, the PGA packages 4 can be put or removed ac the socket body 2 is open. The user can do this work easily. Besides, the actuating arm 63 of the actuating lever 6 can be pt.~ as the groove 631 is retained by the retaining block 22. Hence the sliding support 3 is retained from moving.
Although the present invention has been described in conn~ction with preferred l-ml~im~ntc thereof, many other variations and modifications will now become apparent to those skilled in the art without deptuling from the scope of the mvention. It is preferred, therefore, that the present invention not be limiled by the specific di~clu~ulG herein, but only by the t~;.~,u.led claims.

An ~ct~ ting level 6 defines an actuating portion 61 thereunder. A lug 62 is defined thereof. A post 621 is disposed at said lug 62.
Said post 621 is pivoted to the hole 251 of the projected portion 25. An actuating arm 63 is connected to one side of the actuating portion 61. A groove 631 is defined at the middle portion of the ~ç~l~ting arm 61 which 10 can be positioned to the retaining block 22 of the socket body 2. A sliding support 3 defines a plurality of holes 31 with respect to the slot 21 of the socket body 2. By this arrangement, the pins 41 of the PGA packages 4 can be received by the holes 31. A retaining slot 32 which can engage with the upper portion of the ~tll~ting portion 61 is disposed at the front lower end of the sliding support 3. A cutout 33 is provided at side for the movement of the sliding support 3. The sliding support 3 further includes a hook 34 projected inward and the hook 34 can engage with a notch 26 located at the underside of the socket body 2. By the rotation of the ~c.~ tin~ lever 6, the sliding support 3 is moved on the socket body 2. Since the configuration of the PGA
packages is known by the skilled in the art, and is not the subject matter of the present invention, no further description is given accordingly.
Referring to Figure 3, the pin socket 5 made according to this invention is formed directly from punching a metal sheet. After pin socket 5 is punched, a first supporting arm 52 and a second supporting arm 53 are defined thereof. The first supporting arm 52 is longer than the second supporting arm 53. The first su~u~ Lillg arm 52 and the second SU1~lJUI lillg arm 53 further are formed a first contacting end 54 and a second contacting end 55 respectively at their upper portion. The first contacting end 54 and the second contacting end 55 are intersected with each other. An actuating tab 542 which is illt~l~;umlected with the metal sheet is defined at the first cûnt~rting end 54. A retaining portion 56 is formed at the lower end of the first contacting end 54 and the second cu.,~ i.,g end 55. A leg 57 is defined at the lower portion of the retaining portion 56. A flange portion 541 is defined at one side of the first contacting end 54. When a further m~hining plucedu~ is applied to the raw pin socket 5, a finished pin socket 5 is completed, as shown in Figures 4 and 5A-5C.
CA 0211~403 1998-01-29 As shown in Figures 4 and 5A-5C, a first curve portion 52a is formed at the first supporting arm 52 and a second curve portion 53a is formed at the second ~ul~pul ~illg arm 53. The first curve portion 52a is larger than the second curve portion 53a. By this arrangement, the first contacting end 54 and the second contacting end 55 are separated with each other. A first conductive surface 54a and a second conductive surface 54b is defined at the first co.,~ i.,g end 54 and the second contacting end 55 respectively thereof. A flange 541 is projected outward from the first conductive surface 54a and defines a guiding surface 541a. A guiding surface 551a is defined at the front surface of the second conducting surface 55a.
By this arrangement and layout, the pin socket 5 can be punched directly by a single metal sheet, advantageously, two conductive surfaces 54a, 55a are formed to facilitate an excellent electricity conductivity 10 between the pin 41 of the PGA packages 4 and the pin socket 5. The concentrated force and friction force are reduced accordingly.
Referring to Figures 6A and 6B, the pin socket 5 is inserted and disposed into the slot 21 of the socket body 2. The pin 41 of the PGA packages 4 can pass through the hole 31 of the sliding support 3 and then be retained into the slot 21 of the socket body 2. The actuating arm 63 of the actuating lever 6 shown in Figure 6A
15 is in vertical position, an open position. The pin 41 of the PGA packages 4 is still not engaged with the pin socket 5. At this position, the PGA packages 4 can be easily removed from the sliding support 3 or inserted into the sliding support 3. As shown in Figure 6B, when the actuating arm 63 of the actuating lever is rotated ninety (90) degrees and retained by the retaining block 22, the actuating portion 61 is moved forward with the rotating centre. The retaining slot 32 is moved forward accordingly. As a result, the PGA packages 4 is moved as the 20 sliding support 3 moves. At last, the pin 41 of the PGA packages 4 is engaged with the pin socket 5. The engagement of the pin 41 of the PGA packages 4 and the pin socket 5 will be detailed as described at Figures 7A and 7B.
As shown in Figure 7A, the sliding support 3 is in an open position. Then the PGA packages 4 can be put onto the sliding support 3 making the pin 41 inserts into the slot 21 of the socket body 2 through the hole 25 31 of the sliding support 3. When the sliding support 3 moves traverse, the pin 41 of the PGA packages 4 will insert into the opening between the first contacting end 54 and the second contacting end 55. By this arrangement, the pin 41 of the PGA packages meets the guiding surface 541a of the first contacting end 54 firstly. When the pin 41 keeps on moving in, the first contacting end 54 is biased outward. This can be referred CA 0211~403 1998-01-29 as the first stage contacting. Then the pin 41 meets the guiding surface 551 a of the second contacting end 55 when the pin 41 moves to the one third distance of the first contacting end 54. The second contacting end 55 is biased outward as long as the pin 41 moves in. This is referred to as the second contacting stage. When the sliding support 3 is moved to a desired position, the pin 41 of the PGA packages 4 is positioned and engaged 5 with the first conductive surface 54a and the second conductive surface 54b and form an excellent electricity conductivity. Since the engagement of the pin 41 with the first contacting end 54 and the second contacting end 55 is by two-stage contacting, the friction force generated thereof is largely reduced. The concentrated force which makes the pin 41 to bend is avoided accordingly. As a result, the service life of the pin 41 is prolonged.
As shown in Figures 8A and 8B, another embodiment of the pin socket 5 is shown. The pin socket 5 is inserted into a slot 21a of the socket body 2a by side. The slot 21a is specially designed for the pin socket 5. Accordingly, the orientation is rotated ninety (90) degrees. A retaining slot 32a is disposed at the lower portion of the sliding support 3a. The retaining slot 32a can receive an actuating tap 542 of the first contacting end 54. The diameter of the hole 3 la of the sliding support 3a is larger than the outer diameter of the pin 41 of the PGA socket 4, hence a space is provided for the movement of the pin 41. When the PGA packages 4 is still not inserted into the sliding support 3a and socket body 2a, the first contacting end 54 of the pin socket 5 is inclined outward and openly. When the PGA package 4 is inserted into the socket body 2a, by the same movement, the sliding support 3a is moved traverse, accordingly, the first contacting end 54 is moved accordingly. Then the contacting end 54 is in contact with the pin 41. As the sliding supporting 3a is moved continuously, the second contacting end 55 is in contact with the pin 41. When the sliding support 3a is moved a predet~ n~d position, then pin 41 is positioned with the first conductive surface 54a and a second conductive surface 54b. The pin 41 is clamped by the first conductive surface 54a and a second conductive surface 54b.
The invention can be concluded with the following advantages.
1. The pin socket 5 is directly punched from a metal sheet to form a first supporting arm 52 and a second supporting arm 53, wherein the first supporting arm 52 is longer than the second supporting arm 53.
A first curve portion 52a is formed at the first ~U~JpO~ g arm 52 and a second curve portion 53a is formed at the second ~u~.u. Lillg arm 53. Accordingly, the pin 41 has an even contact with the first contacting end 54 and a second contacting end 55. The pin 41 then has a tight contact with the pin socket 5. An excellent electricity is achieved.

2. A first guiding surface 541a and a second guiding surfaoe SSl a is provided respecfively at the first c~ ing end 54 and the second cont~cting end SS. Then the first cont~cting end 54 and the second C~ ing end SS are biased outward IG~Je~;~ivGly, in two stage. The 1uncG~ tllGd force applied to the pin 41 is reduced advt~ agcuu~l~. As a result, the pin 41 will not bend.
3. A first curve portion 52a is formed at the first su~ulling arm 52 and a second culve portion 53a is formed at the second supporting arm 53. Accoldiilgly, an inserting spaoe (S) is formed thereof, as shown in Figure SB. In light Or this, the lower ponion of the pin 41 is free con~ctinp. wi~h ~he pin socket S. The effective contact focus on the first cont~r~ing end 54 and the second cont:~c~ing end SS. Ilence, the friction force is reduced to the lowest level and the pin 41 will not bend or break off.
4. By the nlOVGIIIGIII of the actuating lever 6, the PGA packages 4 can be put or removed ac the socket body 2 is open. The user can do this work easily. Besides, the actuating arm 63 of the actuating lever 6 can be pt.~ as the groove 631 is retained by the retaining block 22. Hence the sliding support 3 is retained from moving.
Although the present invention has been described in conn~ction with preferred l-ml~im~ntc thereof, many other variations and modifications will now become apparent to those skilled in the art without deptuling from the scope of the mvention. It is preferred, therefore, that the present invention not be limiled by the specific di~clu~ulG herein, but only by the t~;.~,u.led claims.
