[0060] As Figure 1-17 shown, this embodiment discloses a connector, which includes a plugging component 1, an insulating body 2 and a waterproof rubber block 3.

[0061] As Figure 1-4 shown, a cavity 11 is provided at the rear end of the plugging component 1. The plugging component 1 includes a plurality of conductive terminals 12, and part of the conductive terminals 12 are exposed in the cavity 11. A plugging slot is provided at the front end of the insulating body 2, and the front end of the plugging component 1 is located in the plugging slot.

[0062] Waterproof ports 21 are provided on both sides of the insulating body 2. The cavity 11 of the plugging component 1 and the waterproof ports 21 of the insulating body 2 are injection-molded to form the waterproof rubber block 3. Injection molding and filling from both sides of the insulating body 2 can ensure that the cavity 11 of the plugging component 1 is completely filled, enhancing the waterproof effect of the connector and enabling the waterproof ability of the connector to meet the design requirements.

[0063] Specifically, the conductive terminals 12 are divided into two groups, namely the first conductive terminal group and the second conductive terminal group. The multiple conductive terminals 12 within the first conductive terminal group and the second conductive terminal group are arranged side by side and at intervals. The tails of the conductive terminals 12 in the first conductive terminal group and the second conductive terminal group are located on the same plane and are staggered, facilitating soldering connection to the circuit board.

[0064] As Figure 5 and Figure 6 shown, the plug-in assembly 1 includes a first terminal assembly 13 and a second terminal assembly 14 that are mutually adhered. The first terminal assembly 13 includes a first insulating block 131 and a second insulating block 132. The first insulating block 131 is formed at the front end of the first conductive terminal group. At least one side of the front end of the conductive terminals 12 in the first conductive terminal group is exposed outside the first insulating block 131. Preferably, in this embodiment, the first insulating block 131 is injection-molded at the front end of the first conductive terminal group; the tail end of the first insulating block 131 covers the conductive terminals 12 in the first conductive terminal group, and the front part covers the conductive terminals 12, so that part of the left and right sides and the outer side of the conductive terminals 12 are exposed outside the first insulating block 131, so as to abut against the signal terminals of the docking connector to connect the connector and the docking connector. At least two limiting protrusions 1311 are provided on the inner surface of the first insulating block 131, and preferably two in this embodiment. The second insulating block 132 is formed at the tail of the first conductive terminal group (specifically, the second insulating block 132 is injection-molded at the tail of the first conductive terminal group). The tails of the conductive terminals 12 in the first conductive terminal group are exposed at the rear end of the second insulating block 132 for soldering connection to the circuit board.

The third insulating block 141 is formed at the front end of the second conductive terminal group. At least one side of the front end of the conductive terminal 12 of the second conductive terminal group is exposed outside the third insulating block 141. Preferably, in this embodiment, the third insulating block 141 is injection-molded at the front end of the second conductive terminal group; the tail end of the third insulating block 141 is wrapped around the conductive terminal 12 of the second conductive terminal group, and the front end part is wrapped around the conductive terminal 12, so that part of the left and right sides and the outer side of the conductive terminal 12 are exposed outside the third insulating block 141, so as to abut against the signal terminals of the docking connector to connect the connector and the docking connector. A limiting hole 1411 matching the limiting protrusion 1311 is provided on the inner surface of the third insulating block 141. In this embodiment, the number of the limiting holes 1411 is two. During the assembly of the first terminal assembly 13 and the second terminal assembly 14, the limiting protrusion 1311 can be inserted into the limiting hole 1411 to limit the first terminal assembly 13 and the second terminal assembly 14 and prevent them from moving relative to each other. The fourth insulating block 142 is formed at the tail of the second conductive terminal group (specifically, the fourth insulating block 142 is injection-molded at the tail of the second conductive terminal group). The third insulating block 141 and the fourth insulating block 142 are arranged at intervals, and a second sub-cavity is formed in the gap between them. The first sub-cavity and the second sub-cavity form the cavity 11 of the plug-in assembly 1, that is, the gap between the first insulating block 131 and the second insulating block 132 and the gap between the third insulating block 141 and the fourth insulating block 142 form the cavity 11 of the plug-in assembly 1.

[0066] As Figure 9-11 shown, optionally, the plug-in assembly 1 further includes a metal spacer 15 and a metal ring 16.

During the assembly of the plug-in assembly 1, the limiting protrusions 1311 are inserted into the limiting holes 1411 and the mating holes, which can limit the metal spacer 15 and the second terminal assembly 14 and prevent them from being misaligned relative to the first terminal assembly 13.

Specifically, the first connection block 17 is formed on the outer sides of the first insulating block 131 and the third insulating block 141 by injection molding. After molding, both sides of the front end of the metal spacer 15 are partially exposed outside the first connection block 17, and the outer surface of the metal ring 16 is exposed outside the first connection block 17. When this connector is plugged into the docking connector, both sides of the metal spacer 15 can abut against the metal shell or the locking member of the docking connector, and the part of the metal ring 16 exposed outside the first connection block 17 can abut against the metal shell of the docking connector.
