In order to better understand the spirit of the present invention, the following is combined with the preferred embodiment of the present invention. The example is further explained.

As shown in FIG. 2, FIG. 3 and FIG. 4, an electrical connector 1 according to an embodiment of the present invention includes an insulative housing 2, a plurality of terminals 3 received in the insulative housing 2, and a housing that shields the insulative housing 2. 4. The electrical connector 1 is further assembled to a circuit board P for a corresponding docking device 5 to be inserted and docked by the plug terminal 10 in the mating direction A, thereby enabling transmission of high speed differential signals. In order to detect whether the docking device 5 is properly inserted, the electrical connector 1 of the present invention further includes a detecting device 6.

As shown in Figures 4, 5 and 6, the insulative housing 2 has a rectangular parallelepiped body portion 20, a mating portion 21, and a detection space 22 recessed in the body portion 20 and the mating portion 21. The main body portion 20 has a front end face 200 facing the insertion end 10 and a rear end face 201 opposite the front end face 200. The abutting portion 21 is a plate-like body projecting from the front end surface 200 toward the insertion end 10, and the upper portion thereof extends along the insertion end 10 toward the opposite end 11 (hereinafter referred to as "rear end") to form the main body portion 20. There are a plurality of terminal receiving slots 23 arranged in parallel, and the positional structure of each of the terminal receiving slots 23 is determined by the terminal 3 to be accommodated. The detection space 22 is disposed at the top of the insulative housing 2 and includes a P-position slot 220 and a working space 221. The limiting slot 220 is disposed on the side of the main body 20, and includes a first slot 220a extending perpendicular to the plugging direction A and a second slot 220b extending along the plugging direction A. The second slot 220b further penetrates the slot The rear end surface 201 of the main body portion 20 is partially recessed further into the main body portion 20 (not shown). The working space 221 extends from the first slot section 220a of the limiting slot 220, is formed at the top middle of the main body portion 20, and further extends to the top of the abutting portion 21.

The casing 4 is formed by stamping, cutting and bending a metal plate, and has a receiving portion 40 and a rear cover 42 covering the insulating body 2. The accommodating portion 42 forms a socket for inserting the mating device at the plug end 10, and the rear cover 42 is bent downward from the rear end 11 to shield the rear end surface 221 of the main body portion 20. In other embodiments, the rear cover 42 can also be detachably assembled from the receiving portion 42. The accommodating portion 42 further includes a mounting leg 41 extending downward from the accommodating portion 40 for soldering to the corresponding pad P1 on the circuit board P, thereby fixing the housing 4 to the circuit board P ( See Figure 2, 3).

The detecting device 6 includes a detecting terminal 60 and a matching terminal matched with the detecting terminal 60, and when they are in contact, a detection circuit for detecting is formed. In the present embodiment, the matching terminal preferably selects the rear cover 42 of the housing 4, wherein the detecting terminal 60 is disposed in the detecting space 22 of the insulating body 2. The detecting terminal 60 has a holding portion 61 and a A welded portion 62 extending from the end of the holding portion 61 and an abutting portion 63 extending from the other end of the holding portion 61. The holding portion 61 is received in the limiting groove 220, and includes a first holding portion 61a having a corresponding shape of the first groove portion 220a and a second holding portion 61b corresponding to the shape of the second groove portion 220b. The splicing portion 62 is bent downward from the second holding portion 61b of the holding portion 61 and extends outside the limiting slot 220, and further bent a soldering leg 620 for soldering to the corresponding pad P2 on the circuit board P (see Figure 2, 3). The abutting portion 63 has a V shape and includes a first abutting portion 63a extending from the first retaining portion 61a of the retaining portion 61, and a second abutting portion 63b bent from the first abutting portion 63a. The first abutting portion 63a extends obliquely from the first slot portion 220a toward the plug end 10 and protrudes from the top of the mating portion 21 to facilitate pushing the docking device 5 against the top. The second abutting portion 63b extends from the first abutting portion 63a toward the rear end 11 and has a V-shaped end. It is known in the prior art that the docking device 5 has a receiving space that is fully engaged with the mating portion 21. Therefore, in this embodiment, in order to enable the detecting terminal 60 to be pushed after the docking device 5 is inserted, the first one is abutted. The height of the abutting portion 63a must protrude from the surface of the abutting portion 21, that is, the height of the first abutting portion 63a is greater than the depth of the working space 221 at the abutting portion 21, as shown in FIG.

7A-8B are diagrams for explaining the operation of the detecting terminal 60 and the rear cover 42 before and after the docking device 5 interacts with the detecting terminal 60. 7A-7B, the docking device 5 is inserted into the mating end 10 of the electrical connector 1 in the mating direction A. At this time, the abutting portion 63 of the detecting terminal 60 is not in contact with the rear cover 42 of the housing 4, and the detecting terminal 60 is in a free state. As the docking device 5 advances, it comes into contact with the first abutting portion 63a of the abutting portion 63, thereby pushing the entire abutting portion 63 into the working space 221 toward the rear end 11. As shown in FIGS. 8A-8B, when the docking device 5 continues to be fully engaged with the mating portion 21 of the electrical connector 1, the abutting portion 63 of the detecting terminal 60 is completely received in the portion of the working space 221 located on the main body portion 20, The first abutting portion 63a abuts against the docking device 5, and the second abutting portion 63b abuts against the rear cover 42 of the casing 4. At this time, the detecting circuit is turned on to achieve the purpose of detection.

The electrical connector of the present invention is provided with a detecting device for detecting the insertion of the docking device than the existing electrical connector for transmitting the high-speed differential signal, so that it is easy to know the docking situation during use, and avoid the contact failure caused by the insertion of the bit. Or structural damage. The concept of humanized design ensures the stability of the electrical connection and the service life of the product. At the same time, the existing shielding device cooperates with the detection terminal to greatly reduce the cost.

The technical content and technical features of the present invention have been disclosed above, but are familiar with the field. A person skilled in the art can still make various substitutions and modifications without departing from the spirit of the present invention based on the teachings and disclosure of the present invention. Therefore, the scope of the present invention should not be limited by the scope of the present invention, and should be construed as being included in the appended claims.
