Description

plug connector

technical field

The utility model relates to a connector, in particular to a plug connector.

Background technique

Electronic products usually achieve data transmission by docking a plug connector and a socket connector. When the plug connector and the socket connector are docked, the plug terminals of the plug connector are electrically connected to the corresponding socket terminals of the socket connector.

However, when the traditional plug connector is docked with the socket connector, the plug terminal elastically abuts against the socket terminal only from one side, that is, the plug terminal and the socket terminal are only in single-point contact, so when subjected to factors such as shock and vibration When impacting, the connection between the plug terminal and the socket terminal is prone to the problem of momentary disconnection.

Utility model content

The purpose of this utility model is to provide a plug connector for the defects of the above-mentioned background technology, the plug terminal of the plug connector can stably contact the socket terminal of the mating socket connector.

To achieve the above purpose, the plug connector provided by the utility model includes an insulating body and a plurality of plug terminals. The insulating body has a body base and a tongue body. Several terminal slots are opened on the body base. The tongue body has an upper surface and a lower surface. The plug terminal is inserted into the terminal slot, and has a first contact portion extending backward. The end of the first contact portion is bent to extend a clamping portion, and the end of the clamping portion extends forward to form a second contact portion. , the first contact portion and the second contact portion are respectively disposed on the upper surface and the lower surface of the tongue body.

As mentioned above, since the plug terminal of the plug connector of the present invention has a first contact portion and a second contact portion, and the first contact portion and the second contact portion are respectively provided on the upper surface and the lower surface of the tongue portion, Therefore, when the plug connector of the present invention is docked with the socket connector, both the first contact portion and the second contact portion of the plug terminal can be electrically connected to the socket terminal of the socket connector, so that the plug terminal of the plug connector can be connected to the socket connector. The socket terminal of the butt socket connector achieves a reliable connection, thereby avoiding the occurrence of momentary disconnection.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the utility model in detail, the following will be described in detail in combination with the embodiments and accompanying drawings.

Please refer to FIG. 1 , the plug connector 100 of the present invention includes an insulating body 1 , an insulating seat 2 , several plug terminals 3 and a metal sleeve 4 .

Please refer to FIG. 2 and FIG. 3 , the insulator body 1 has a roughly cuboid body base 11 , the rear end surface of the body base 11 protrudes from a substantially square socket joint 12 and is located at the socket joint respectively. 12, the two surrounding body parts 15 on the left and right sides, and a sheath groove 16 is respectively formed between the two surrounding body parts 15 and the casing connecting part 12. Two guiding posts 13 and a generally plate-shaped tongue 14 located between the two guiding posts 13 extend from the rear end of the sleeve body connecting portion 12 . A substantially square seat body docking portion 17 protrudes from the middle of the front end of the body base 11 .

The body base 11 defines a groove 111 on the upper and lower surfaces, and two fixing holes 19 are defined on the body base 11 through the front and rear surfaces of the body base 11 . A locking block 112 protrudes from the bottom walls of the two grooves 111 . A plurality of terminal slots 18 are provided on the insulating body 1 . The terminal socket 18 has an engaging groove 181 defined on the bottom wall of the groove 111 and a receiving groove 182 defined on the upper and lower surfaces of the tongue portion 14 .

Please refer to FIG. 2 , the insulating base body 2 is roughly in the shape of a cube, and a rectangular card slot 21 is defined on its upper surface. A square seat groove (not shown in the figure) is provided on the rear surface of the insulating seat body 2, and the seat groove accommodates the seat body butt joint portion 17 of the insulating body 1, so that the insulating seat body 2 is mounted on the insulating body 1 . The insulating base body 2 is also provided with two fixing holes 22 and a plurality of plug terminal tail holes 23 passing through the insulating base body 2 front and back.

Please refer to FIG. 3 and FIG. 4 , the plug terminal 3 has a block portion 32 , and a strip-shaped retaining strip 31 extends forward from the front edge of the block portion 32 . The middle part of the rear edge of the block portion 32 bends and extends a bending portion 33, and the end of the bending portion 33 extends backwards to a first contact portion 34, and the end of the first contact portion 34 bends and extends a roughly The clamping portion 35 is semi-circular, and a second contact portion 36 is formed at the end of the clamping portion 35 extending forward.
