Detailed ways

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

Please refer to Fig. 2 and Fig. 3, the electric connector of the present utility model comprises an insulating body 10 and several connecting terminal groups, and these several connecting terminal groups respectively comprise a seat terminal 20 which is made of a spring type by a spring manufacturing machine and a spring The manufacturing machine makes the abutting terminal 30 of elastic sheet type.

Please refer to Figures 2 to 4, the insulating body 10 is roughly in the shape of a cuboid, and several openings 11 are provided on the top wall of the insulating body 10. The terminal accommodating groove 12 communicates with an opening 11 , and a holding groove 121 is defined on a side wall of the terminal accommodating groove 12 .

The spring type seat terminal 20 has a flat base portion 21, two holding portions 22 formed by bending and extending from one side of the base portion 21, and two elastic arms formed by extending upward and outward from the end of a holding portion 22, respectively. 23 and two bending parts 24 that are formed by bending and extending inwardly from the end of an elastic arm 23 respectively. The two sides of the holding part 22 protrude outwards with several locking teeth 221, and there is a slot 241 in the middle of the end edge of the bending part 24. .

The spring type abutment terminal 30 has a bent portion 31 and two elastic arms 32 extending outwardly from one side of the bent portion 31 respectively. part 33 , two sides of the holding part 33 respectively extend outward to form an extension arm 34 .

The clamping portion 33 of the abutting terminal 30 of the electrical connector of the present utility model is slidably abutted against the inner side of the corresponding elastic arm 23 of the seat terminal 20, the elastic arm 32 passes through the slot 241 of the seat terminal 20, and the bending portion 24 The extension arm 34 can be held to prevent the abutment terminal 30 from disengaging from the seat terminal 20 and falling off. The seat terminal 20 and the abutment terminal 30 are accommodated in the terminal accommodating groove 12 of the insulating body 10, and the holding part of the seat terminal 20 22 is held in the holding groove 121 of the insulator body 10 by the locking teeth 221, the ends of the two elastic arms 23 elastically abut against the groove wall of the terminal accommodating groove 12, and one end of the bending part 31 abutting against the terminal 30 is movably protruded in the opening 11 of the insulating body 10 .

Please refer to FIG. 3 and FIG. 4 , when the electrical connector of the present invention is in operation, when the butt connector pushes against the abutment terminal 30 , the elastic arm 32 of the abutment terminal 30 is pushed by the elastic arm 23 of the seat terminal 20 , Therefore, the abutting terminal 30 slides, and when the abutting terminal 30 disengages from the docking connector, the clamping portion 33 of the abutting terminal 30 pushes against the elastic arm 23 of the seat terminal 20 and slides to a position below the bending portion 24 .

To sum up, the electrical connector of the present invention uses the seat terminal 20 and the abutment terminal 30 to engage with each other in the form of a shrapnel. The design structure is simple and the assembly is simple, thereby saving costs.
