The terminal assembly of the present invention can be realized by the following technical solutions: a terminal assembly comprising an insulative housing, a plurality of conductive sheets received in the insulative housing, and a plurality of elastic terminals disposed under the electrically conductive sheet and electrically connected thereto The conductive sheet includes a bottom plate in a flat shape and an abutting portion protruding above the bottom plate. The conductive sheet is embedded in the insulating body, and the elastic terminal is overmolded with an insulating block.

Compared with the prior art, the present invention has the following effects: the conductive sheet is embedded and molded in the insulating body, so that the butt end of the terminal assembly has a good waterproof effect, and the elastic terminal is embedded and molded in the insulating block and can be electrically conductive. The piece is in reliable contact.

The middle portion of the through hole 12 has a rectangular shape, and both ends of the through hole 12 It is semi-circular. The lower surface of the insulative housing 1 is recessed upward to form a first recess 13 , and the first recess 13 is in communication with the left and right surfaces of the insulative housing 1 . The bottom surface of the first recess 13 is provided with a second recess 14 , and the bottom surface of the second recess 14 is provided with a plurality of third recesses 15 , and the third recess 15 is communicated with the corresponding through hole 12 . Third groove The size of 15 is larger than that of the through hole 12. The two recesses 14 are recessed outwardly on the two sides of the second recess 14 to form a notch 16 . The pair of notches 16 are disposed face to face and communicate with the second recess 14 . The recess 16 does not penetrate the insulative housing 1 . . A projection 141 is formed on the two sides of the second recess 14 in the front-rear direction, respectively, toward the first recess 13 . The pair of recesses 141 and the pair of notches 16 respectively occupy different sides in the second recess 14 .

The conductive sheet 2 is made of a metal material and is provided in plurality and evenly arranged in the lateral direction. Each of the conductive sheets 2 includes a bottom plate 21 in a flat shape and a mating above the bottom plate 21 for mating with the mating connector. Part 22. The bottom plate 21 is a rectangular parallelepiped, and the bottom plate 21 is received in a corresponding third recess 15 at the bottom of the insulative housing 1. The abutting portion 22 is integrally formed with the bottom plate 21, and the intermediate portion of the abutting portion 22 has a rectangular shape. The two ends of the abutting portion 22 are semi-circular, and the abutting portion 22 is received in the corresponding passage of the insulating body 1. In the hole 12.

The elastic terminal 3 is a pogo pin (a movable pin that is stretched by a spring), and the number thereof is equal to the number of the conductive sheets 2 and the number of the through holes 12 and the third grooves 15. The top end of each of the elastic terminals 3 is a semi-spherical contact portion 31, and the contact portion 31 is electrically connected to the corresponding conductive sheet 2.

The insulating block 4 is overmolded outside the elastic terminal 3, and the plurality of positioning grooves 41 are arranged on the insulating block 4 in the lateral direction, and the insulating block 4 is penetrated from the top to the bottom. An opening 42 is formed in each of the two ends of the insulating block 4 in the lateral direction, and the opening 42 penetrates the insulating block 4 from the top to the bottom and communicates with the outside.

When the terminal assembly 100 of the present invention is assembled, the conductive sheet 2 is first embedded in the insulative housing 1 , so that the butt end of the terminal assembly 100 has a good waterproof effect and is aesthetically pleasing, wherein the mating portion 22 contained in insulation The bottom plate 21 is received in the corresponding third through hole 15 in the corresponding through hole 12 of the body 1. The elastic terminal 3 is embedded in the insulating block 4, and the elastic terminal 3 is fixed in the corresponding positioning groove 41. Then, the insulating block 4 to which the elastic terminal 3 is fixed is placed in the second recess 14 at the bottom of the insulative housing 1, wherein the upper surface of the insulating block 4 rests on the bosses 141 on both sides of the second recess 14, and the insulating block 4 The openings 42 of the ends are respectively disposed opposite to and corresponding to the corresponding notches 16 in the insulative housing 1.
