ELECTRICAL CONNECTOR HOUSING HAVING PANEL MOUNTING AND LATCHING MEANS Filed Nov. 7, 1962 2 Sheets-Sheet 1 P" 1965. R. DE- LYON 3,17 3

ELECTRICAL CONNECTOR HOUSING HAVING PANEL MOUNTING AND LATCHING MEANS Filed Nov. 7, 1962 2 Sheets-Sheet 2 ELECTRICAL CQNNECTOR HOUSING HAVING PANEL MUUNTING AND LATCHENG MEANS Ren de Lyon, Harrisburg, Pa., assignor to AMP Incorporated, Harrisburg, Pa. 7 Filed Nov. 7, 1962, Ser. No. 236,061 I 7 Claims. (Cl. 174-50) This invention relates to separable electrical connector assemblies for disengageably connecting a plurality of conductors.

An object of the invention is to provide an improved separable connector housing, both parts of which can be formed as a unitary molding. A further object is to provide a connector housing having positive latching means for holding the two parts of the connector in engagement-with each other. A still further object of the invention is to provide a'housing having improved means for mounting on a panel or wall. A'still further object is to provide an electrical connector which can be mounted ends by means of integral struts in a manner such that the rearward endsof the housing units can be moved relatively towards each other upon deformation of the struts.

By virtue of this arrangement, this socket part of the connector assembly can be inserted partially through an opening in the panel. Forwardly facing abutments are provided on the oppositely facing sides of the housing units so that after partial insertion of the housing units through the panel opening, these abutments or shoulders 'will bear against the one side of the panel and prevent withdrawal thereof from the panel. In order positively to lock this connector part to the panel, I provide flexible stopsin the form of a bridge or a beam supported at 'each end which'connects theremaining pairs of adjacent sides of the housing units.

These flexible stops each have a rearwardlyfacing surface, the plane of which is parallel to the planes of the abovementioned abutments or shoulders so that the stops are resiliently deformed and bear against the opposite side of the panel after insertion. The stops thus function to press the shoulders against the panel and securely lock the connector part in place.

The mating section of the connector, the plug, comprises two housing units which are spaced apart and integrally joined along their opposing sides by a strut member and which are adapted to enter the forward ends of the housing units of the socket part. Latch means for securing the two connector parts together after assembly is provided in the form of a pair of latch bars located between the two housing units of the plug and mounted on integral struts which extend between the housing units, the struts, the housing units, and the latch bars being formed as an integral molding. At their rearward ends, the latch bars have projecting finger grip portions which extend beyond the surface of the housing while their forward ends have reversely directed hooks for engagementwith the connecting struts of the. socket portion of the assembly. The two parts of the connector assembly can thus be engaged with each other by merely "grasping the finger grip sections of the latching bars of the plug portion, depressing these latch bars, moving the United States Patent O "ice connector parts into engagement with each other and releasing the latch bars to permit their hooked ends to engage the strut members of the socket portion.

in the drawing:

FIGURE 1 is a perspective view of a connector plug and socket in accordance with the invention.

TGURES 2 and 3 are views taken along the lines 2-2 and 3--3 of FIGURE 1.

FIGURE 4 is a sectional view showing the plug and socket portions in engagement with each other and illustrating the function of the latching bars.

FIGURES Sand 6 are views illustrating the manner in which the socket member is mounted in an opening in a panel or wall. 7

Referring first to FIGURE 1 in the drawing, the dis closed embodiment of the invention comprises a connector assembly consisting of a plug section 2 and a socket section 4, each of which sections contains a plu- 8, 8'. These struts are separated by an off-center slot 14 and extend only partially along the opposing walls of the forward housing sections 8, 8' so that the rearward ends of the housing sections 6, 6' can be moved relatively towards and away from each other with concomitant elastic deformation of the struts. The rearward sides of these struts function as shoulders for engagement by a latch arm as more fully described below.

The sides 16,16 of the rearward sections of the housing. units which face outwardly and in opposite directions have adjacent to their extreme rearward ends, bosses 18, 18'. which define forwardly facing shoulders 19. These shoulders are adapted to bear against-one side of a panel P to which the socket section 4 is secured. The adjacent coplanar parallel sides 20, 20' and 21, 21' of the rearward sections are integrally joined by means of stops 24 which bridge these two members and which are integral with their remote sides 16, 16 by means of upstanding lugs or bosses 22, 22'. The stops 24 are preferably of a substantial width and are generally curved towards the rearward ends of the receptacle member so that they present a substantial bearing surface which is opposed indirection to the bearingsurfaces of shoulders 19. These stops are again relatively flexible so that they can be elastically deformed during use as is described below.

When it is desired to mount the socket section 4 in an opening in a panel P having a width substantially equal to or slightly greater than the distance between the sides 16, 16 the socket is aligned with the opening as indicated in FIGURE 5 and forced through the opening until the shoulders 19, 19' bear against the right hand side of the panel as viewed in FIGURES 5 and 6. During movement of the receptacle through the panel, the stop 24 will be brought to bear against the lefthand side of the panel and will be flexed after the manner of a simple beam which is fixed at both ends. Thus, the stops 24 will tend to bias the two housing sections apart thereby to prevent accidental or unintentional removal of the housing receptacle from the panel. Advantageously, the distance between the plane of the shoulders 19 and the face of the stop 24 is less than the thickness of the panel in which the receptacle is mounted so that after mounting, the stops will not be permitted to return to their normal condition but will rather be slightly elastically deformed and provide a continuing resilient force which both hold the shoulders 19 closely against the opposite -web and slot arrangement.

side of the panel and biases the two housing sections 6, 6 away from each other.

The plug section 2 of my preferred embodiment comprises two substantially rectangular and substantially i identical housing units 26, 26 which are secured together in side-by-side relationship by means of an integral flat web 28 extending between their opposed sides. The two housing units 26, 26 thus form a recess within which a latch arm 3-0 is disposed. The location of this web is offcenter by the same amount as is the location of the slot 14, thus providing a convenient means of polarizing the two housing parts since they can be assembled in only the proper and intended manner by virtue of this off-center Latching arms 30, are contained between the opposed faces of the housing units 26, 26 adjacent to the tops and bottoms of the units and are integral with a torsionally deformable pin 34 which is also integral with the opposed sides of the housing units. At

-their forward ends as Viewed in FIGURE 2, the latch arms have inwardly directed hook portions 32 adapted to be engaged with the ends of the struts lit, 12 of the receptacle 4. At their rearward ends or their lefthand ends ,as viewed in FIGURE 2, the latch arms extend above the surfaces of the housing units and are integral with transverse finger piece sections 36. These finger piece sections extend across and bridge both of the housing units and are integral with each of the housing units at their ends.

It will be apparent that when it is desired to engage the two connector parts with each other, it is merely necessary to grasp the finger pieces 36 between the thumb and forefinger, press them together to torsionally deform the pin 34 and thereby raise the hooked ends of the latch arms, move the two parts into engagement with each other, and release the finger pieces.

The disclosed embodiment of the invention is provided with cavities adapted to receive the hermaphrodite type vof contact terminal disclosed in US. Patent 2,891,103

although alternative types of contacts can be used. will be understood that with this type of contact, the ends of the contacts in socket section 4 will be disposed in the hollow forward housing sections 8, 8' While the contacts in the plug 2 will be entirely contained in the cavities of the housing units 26, 26'.

A salient advantage of the invention is that it achieves both positive locking of one of the connector parts, the socket 4, to the panel (by virtue of the beam action stops .24 in cooperation with the shoulders 19) and positive .locking of the plug member 2 to the socket member 4 by virtue of the latching mechanism comprising the latch Moreover these functions are achieved in a manner such that both the plug and the socket member can be made as a single integral molding of a suitable relatively firm plastic material such as a suitable nylon. The socket member 4 can, moreover, be mounted in panels of varying thickness and in openings of varying size.

Changes in construction will occur to those skilled in the art and various apparently different modifications and embodiments may be made without departing from the scope of the invention. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only.
