The first insulating body 1 has a first interface 11, a second interface 12, and a bypass extension port 13. In this embodiment, the first insulating body 1 is flat, the opening directions of the first interface 11 and the second interface 12 are opposite, and the opening direction of the extension port 13 is perpendicular to the opening directions of the first interface 11 and the second interface 12, thereby obtaining a better connection direction and facilitating the insertion and extraction implementation. The first terminal 2 is assembled on the first insulating body 1. The first terminal 2 has a first contact end 21, a second contact end 22, and a splicing portion 23; the first contact end 21 extends into the first interface 11, the second contact end 22 extends into the second interface 12, and the splicing portion 23 can be conductively connected to the second terminal 3 through the extension port 13. The second terminal 3 is positioned on the second insulating body 4 and cooperates with the second insulating body 4 to jointly construct an external plugging system; a first plugging and assembling portion 41 is provided on the second insulating body 4, and the first plugging and assembling portion 41 is plugged and connected to the extension port 13, so that the second insulating body 4 is spliced onto the first insulating body 1. A second plugging and assembling portion 51 is provided on the cover plate 5. By plugging the second plugging and assembling portion 51 into the extension port 13, the cover plate 5 can cover the extension port 13 when the second insulating body 4 and the second terminal 3 are not plugged. The cover plate 5 and the second insulating body 4 are selectively assembled onto the first insulating body 1, that is, when using the second insulating body 4, the cover plate 5 needs to be removed and reserved; when the second insulating body 4 is removed, covering the cover plate 5 plays a protective role.

[0025] Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, in this embodiment, the first terminal 2 is assembled into the preset terminal holes on the first insulating body 1 by implanting and is clamped by an anti-withdrawal hook, so that the first terminal 2 is stable on the first insulating body 1. There are multiple first terminals 2 in this embodiment and they are arranged in a line to meet the signal transfer requirements. The second terminal 3 is also assembled into the preset terminal holes on the second insulating body 4 by implanting and is clamped by an anti-withdrawal hook, so that the second terminal 3 is stable on the second insulating body 4. The quantity and arrangement of the second terminals 3 in this embodiment match those of the first terminals 2. The splicing portion 23 on the first terminal is a blade structure formed by locally flattening the first terminal 2, which increases the contact area. A pair of elastic clamping arms 31 for clamping the splicing portion 23 are provided on the second terminal 3; during assembly, the pair of elastic clamping arms 31 are inserted into the extension port 13 and clamp the splicing portion 23, and are symmetrically clamped left and right to ensure stable connection and contact area and improve the transmission performance.

[0026] Figure 1 , 2As shown in FIGS. 3 and 4, a pair of elastic clamping arms 31 of this embodiment protrude from the first plug-in and assembly part 41 of the second insulating body. The first plug-in and assembly part 41 includes a first insertion rubber position 411 and a first flange 412 distributed on the outer periphery of the first insertion rubber position 411. The shape and size of the first insertion rubber position 411 match the expansion port 13, and a first barb 413 is provided on the outside of the first insertion rubber position 411. During assembly, the first insertion rubber position 411 is inserted into the expansion port 13 and is clamped to a hanging platform 131 preset on the peripheral wall of the expansion port through the first barb 413 to establish an anti-disconnection connection, and the first flange 412 presses against the port of the expansion port. This structure ensures that the pair of elastic clamping arms 31 are inserted into the connection splicing part 23, and at the same time increases the connection between the first plug-in and assembly part 41 and the expansion port 13. The first flange 412 plays a role in limiting the insertion depth and increasing the contact support, preventing the second insulating body 4 from swaying, improving the assembly stability, and facilitating subsequent plugging and unplugging operations. In this embodiment, the first flange 412 is an annular structure surrounding the first insertion rubber position 411, and a first avoidance notch 414 is provided at a part of the first flange 412. The first avoidance notch 414 and the first barb 413 are in a vertically opposite relationship. This structure increases the support area of the first flange 412 and has a good dust-proof effect. The design of the first avoidance notch 414 can facilitate the use of tools to release the clamping of the first barb 413, so as to disassemble the second insulating body 4, increasing the practicality.

The shape and size of the second insertion rubber position 511 match the expansion port 13, and a second barb 513 is provided on the outside of the second insertion rubber position 511. During assembly, the second insertion rubber position 511 is inserted into the expansion port 13 and is clamped to a hanging platform 131 preset on the peripheral wall of the expansion port through the second barb 513 to establish an anti-disconnection connection, and the second flange 512 presses against the port of the expansion port. This structure increases the connection structure between the second plug-in and assembly part 51 and the expansion port 13. The second flange 512 plays a role in limiting the insertion depth and increasing the contact support, improving the assembly stability. Further in this embodiment, the second flange 512 is an annular structure surrounding the second insertion rubber position 511, and a second avoidance notch 514 is provided at a part of the second flange 512. The second avoidance notch 514 and the second barb 513 are in a vertically opposite relationship. This structure increases the support area of the second flange 512 and has a good dust-proof effect. The design of the second avoidance notch 514 can facilitate the use of tools to release the clamping of the second barb 513, so as to disassemble the cover plate 5, increasing the practicality.
