The fourth figure is a view of another angle of the third figure; and

The fifth drawing is a cross-sectional view of the second drawing taken along line V-V.

The specific embodiment of the novel electrical connector will be described in detail below with reference to the drawings.

Referring to the first and second figures, the electrical connector 100 is used for mating with the mating connector 200 having the elastic probe 201. The electrical connector 100 includes an insulative housing 10 and a conductive terminal 20 disposed on the insulative housing. The insulative housing defines an abutting surface 101 (ie, a front end surface) and a foolproof hole 102 extending through the mating surface 101. The anti-dwelling hole can be engaged with the guiding post 202 of the mating connector. It should be noted that the foolproof hole 102 is not located at the center of the mating face, but is offset to one side to prevent mis-insertion of the docking connector. In the preferred embodiment, the foolproof hole 102 is located at the outermost side. Between the conductive terminals 20. The anti-dwelling hole and the guiding post have a substantially rectangular structure.

In conjunction with the third and fourth figures, the insulative housing 10 is provided with a plurality of terminal slots 103 for receiving the conductive terminals 20, and the terminal slots 103 extend through the mating surface 102 and the rear end surface 104 of the insulative housing. The terminal groove 103 is provided with a holding groove 1031 which is located on the upper and lower sides and penetrates the rear end surface 104, and a through hole 1032 penetrating the abutting surface, and the contact portion 23 is accommodated in the through hole.

The conductive terminal 20 is mounted in the terminal slot 103 from the rear end surface, and includes a connecting portion 21, a fixing portion 22 held by the insulating body, and a contact portion 23 exposed on the mating surface via the terminal slot. The fixing portion 22 has a flat shape and has a U shape. The fixing portion 22 extends from the thickness direction of the flat plate toward the abutting surface 101 to form the contact portion 23. With particular reference to the fifth figure, the front end face of the contact portion 23 is just flush with the mating face 101. Of course, since the elastic probe 201 of the docking connector 200 protrudes forward, the contact portion 23 can be slightly recessed into the abutting surface 101 and slightly protruded outside the mating surface as long as it is easy to be docked. Since the contact portion 23 is formed in the thickness direction and extends in the butting direction, its mechanical strength is high, and sufficient mating holding force can be provided at the time of docking without deformation.

In the preferred embodiment, the fixing portion 22 further includes a first fixing portion 221 fixed to the upper and lower holding grooves, a second fixing portion 222, and a bridge portion 223 connecting the first and second fixing portions, and the bridge portion 223 is attached. On the rear side of the abutting surface 101 (refer to FIG. 5) and parallel to the abutting surface 101 of the insulative housing, the first and second fixing portions 221, 222 are parallel to each other and perpendicular to the abutting surface 101. The contact portion 23 is formed by punching and protruding from the bridging portion 223 in the direction of the abutting surface, and the connecting portion 21 extends perpendicularly from the second fixing portion 222 to the rear end surface 104 of the insulative housing 10. The first fixing portion 221 and the second fixing portion 222 are both provided with barbs, and can be interference-fitted with the corresponding holding grooves 1031.

The connecting portion 21 can be electrically connected to other electronic components (such as a circuit board, a cable, etc.). In the present embodiment, the connecting portion 21 serves as a soldering portion soldered to a circuit board (not shown). The insulative housing 10 extends rearwardly from the sides thereof to form a wing portion 11. The wing portion 11 and the rear end surface 104 enclose a receiving space 105 for receiving the connecting portion 21, thereby protecting the connecting portion 21 from being collided by other components. The wing portion 11 is provided with a mounting surface 110 and a mounting post 111 for projecting the mounting surface 10 for securing the electrical connector to the circuit board. The mounting surface 110 is perpendicular to the mating surface 101, and the connecting portion 21 protrudes from the mounting surface.

In view of the above, the above is only a preferred embodiment of the present invention, and those skilled in the art can still make various substitutions and modifications without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be limited by the scope of the invention, and all the equivalent equivalents and modifications of the present invention are intended to be included within the scope of the following claims.
