The connector body 100 is described in detail with reference to fig. 1-3.

The connector body 100 is composed of a rubber shell 101 with a socket 1011 at one side and a plurality of terminals 102 arranged in the rubber shell 101, the front end of the rubber shell 101 is provided with the socket 1011, and two ends of the socket 1011 are provided with a cavity 1012 which is matched and connected with the positioning piece 300. The rear end of the rubber shell 101 is provided with a connecting groove matched with the contact pin, the connecting groove is communicated with the socket 1011, and one end of the terminal 102 is arranged in the socket 1011 from the connecting groove, so that the flat cable 200 is convenient to connect and conduct.

In order to improve the connection strength of the flat cable 200 and to facilitate the plugging of the flat cable 200, a connection cavity 1015 with a C-shaped structure is provided between the cavity 1012 and the socket 1011, and the positioning plate 300 is fixed in the rubber casing 101 through the cavity 1012.

Specifically, a through groove 1014 communicating with the cavity 1012 is further provided on the top surface of the rubber casing 101, so as to facilitate connection of the positioning sheet 300.

The spacer 300 is described in detail with reference to fig. 6-7.

The positioning sheet 300 is composed of a positioning section 301, a limiting section 302 and an elastic portion 303 with a U-shaped structure, wherein the positioning section 301, the limiting section 302 and the elastic portion 303 are all of an integrated structure, i.e. the positioning sheet 300 is formed by bending a whole plate.

Specifically, the positioning section 301 is disposed above the limiting section 302, the middle of the positioning section 301 is provided with a supporting portion 3021 extending horizontally to the left and right sides, a groove 1013 is disposed in the cavity 1012 for limiting the cavity 1012, and the groove 1013 is disposed on the left and right sides of the upper portion of the cavity 1012.

Preferably, the width of the supporting portion 3021 is slightly larger than the width of the recess 1013 so as to facilitate the interference fit between the positioning sheet 300 and the recess 1013, for increasing the overall connection strength and preventing the positioning sheet 300 from slipping out or backing back after being inserted into the cavity 1012.

Further, a bending section 3011 welded with the PCB board 400 is disposed at the left side of the end of the positioning section 301, where the bending section 3011 is an L-shaped structure formed by bending a transverse plate extending leftwards twice by 90 ° and the bottom surface of the bending section 3011 is welded and fixed with the PCB board 400. It should be noted that, the structures of the positioning pieces 300 disposed at the left end and the right end of the rubber case 101 are mirror images of each other, that is, the bending section 3011 of the positioning piece 300 disposed in the left end cavity 1012 is disposed at the left side, and the bending section 3011 of the positioning piece 300 disposed at the right end is disposed at the right side of the positioning section 301. The following description will be made with reference to the positioning plate 300 disposed in the cavity 1012 at the left end of the rubber housing 101.

Specifically, referring to fig. 4-7, a clamping plate structure 304 extending rightward is disposed in the middle of the limiting section 302, the clamping plate structure 304 is matched with the connecting cavity 1015, the clamping plate structure 304 extends horizontally to the left, and a limiting block 3041 is bent upward at the end of the clamping plate structure 304.

Preferably, the limiting block 3041 is perpendicular to the clamping plate structure 304, so as to clamp the flat cable 200 on the left side of the socket 1011 through the connecting cavity 1015 with the limiting block 3041. The front side of the limiting block 3041, i.e. the side close to the opening of the socket 1011, is provided with an inclined surface 3042, so that after the flat cable 200 abuts against the inclined surface 3042, the limiting block 3041 moves downward and the whole limiting section 302 also moves downward for a distance. The rear side of the limiting block 3041 is a vertical plane, and is used for preventing the flat cable 200 from falling out, and a notch 202 which is matched and clamped with the limiting block 3041 is arranged at the end part of the flat cable 200.

Further, the pressing structure 305 is disposed on the right side of the end of the limiting section 302, and is a C-shaped bending structure, and a pressing plate 3051 is disposed at the end of the pressing structure 305. Wherein, the pressing plate 3051 is disposed above the positioning section 301, i.e. after the positioning plate 300 is disposed in the cavity 1012. The pressing structure 305 cooperates with the through slot 1014, so that the pressing plate is disposed above the glue shell 101, and the pressing plate 3051 is pressed downward, so as to drive the clamping plate structure 304 to move downward.

The end of the flat cable 200 is provided with a connector 201, and notches 202 are provided on the left and right sides of the connector 201.

Working principle: after the flat cable 200 is inserted into the socket 1011, the front end of the connector 201 is abutted against the inclined surface 3042 of the limiting block 3041, and the whole limiting section 302 is bent downwards; when the flat cable 200 is inserted, the limiting section 302 is rebounded to the original position under the action of the elastic portion 303, that is, the limiting block 3041 is clamped into the notch 202, so as to complete limiting. When the flat cable 200 needs to be pulled out, only the pressing plate 3051 needs to be pressed downwards, so that the limiting section 302 moves downwards, and the flat cable 200 can be taken out after the limiting block 3041 and the notch 202 are released from limiting, so that the flat cable is convenient and reliable.

The above examples are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the spirit and scope of the present utility model. Various modifications and improvements of the technical scheme of the present utility model will fall within the protection scope of the present utility model without departing from the design concept of the present utility model, and the technical content of the present utility model is fully described in the claims.
