[0038] Please refer to Figures 3 to 10 The insulating body 1 includes a base 11, a tongue plate 12 disposed at the front end of the base 11, and a tail plate 13 disposed at the rear end of the base 11. The base 11 has a plurality of terminal slots 10, which are extended along the front-to-back direction M, and the terminal slots 10 are provided with bosses 5. A plurality of conductive terminals 2 include a head 201, a middle portion 202, and a tail portion 203. The conductive terminals 2 pass through the terminal slots 10, the head 201 is exposed on the surface of the tongue plate 12, the tail 203 is exposed on the surface of the tail plate 13, and the middle portion 202 is in contact with the boss 5. The metal shell 3 is sleeved on the outside of the insulating body 1, and the tail plate 13 is exposed from the metal shell 3. The insulating sleeve 4 is disposed on the rear side of the metal shell 3 and covers the tail plate 13. Such a configuration can prevent the insulating sleeve 4 from flowing into the tongue plate 12 through the tail plate 13 and the terminal slot 10 in sequence during the injection molding process, thereby affecting the contact effect of the conductive terminal 2.

[0039] In this embodiment, the tongue plate 12 and the tail plate 13 are staggered in the thickness direction TT, so that the tongue plate 12, the base 11 and the tail plate 13 form a “Z”-shaped structure.

In this way, when the conductive terminal 2 is arranged in the terminal groove 10 of the insulating body 1, the first boss 51 and the second boss 52 can prevent the molten rubber from flowing into the tongue plate 13 through the tail plate 13 and the terminal groove 10 in sequence during the injection molding process of the insulating sleeve 4, thereby affecting the contact effect of the conductive terminal 2.

The widths of the first sub-terminal slot 102 and the second sub-terminal slot 103 are smaller than the main terminal slot 101, so that the main terminal slot 101, the first sub-terminal slot 102 and the second sub-terminal slot 103 form a "cross" structure. The first boss 51 is disposed on the top surface 1020 of the first sub-terminal slot 102, and the second boss 52 is disposed on the bottom surface 1030 of the second sub-terminal slot 103, so that it can be more compactly matched with the conductive terminal 2.

In this way, it is possible to prevent the molten rubber from flowing into other parts of the contact portions 204 through the terminal slots 10 during the injection molding process of the insulating sleeve 4, thereby affecting the contact effect of the conductive terminal 2.

[0045] Please refer to Fig.13 The first conductive terminal 21 is provided with a tilting portion 211, which tilts from the middle portion 202 of the first conductive terminal 21 to the slot top surface 1020, and the tilting portion 211 abuts against the slot top surface 1020.

In this way, the fluid material of the insulating sleeve 4 can be prevented from flowing into the contact portion 204 of the second conductive terminal 22 through the second terminal groove 10B, thereby affecting the contact effect of the second conductive terminal 22.

[0047] Please refer to Figure 1 to Figure 2 The electrical connector 100 further includes a plurality of cables 6, and the plurality of cables 6 are connected to the tail portion 203 of the conductive terminal 2. In this embodiment, the cables 6 include two electronic wires 61 and an insulating layer 62 wrapped around the two electronic wires 61. The two electronic wires 61 can be tinned copper or silver-plated copper.
