[0002] A terminal connector is an electrical connector that can bridge two conductors on a loop so that current or signals can flow from one conductor to another conductor. For example, in the patent number "CN216436210U" and the patent name "A terminal connector", when the staff needs to clamp and fix the wire on the second body, they need to first pass the wire through a number of tongues distributed on both sides of the length direction of the second body, and then bend the tongues to abut on the wire, so as to clamp the wire, and then insert the second body into the first slot until the hard barb abuts on the side wall of the card plate facing the back of the insertion surface, and then insert the locking plate into the first slot, and make the locking plate abut on the locking plate, and then the locking ring is buckled on the locking block. However, the above structure still has the following problems in actual use:

[0003] When the terminal connector is in use, the wires and the locking grooves are exposed to the air, so that dust in the air can easily fall onto the surface. Excessive accumulation of dust can easily affect the stability of the connection, resulting in poor practicality.

[0004] Therefore, we proposed a dustproof terminal connector that can solve the above problems well. Utility Model Content

[0014] Preferably, the inclined block is rotatably arranged inside the male plug, and a third return spring is fixed to the inner side of the inclined block, and the other end of the third return spring is fixed to the male plug.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the dustproof terminal connector can not only achieve a sealing effect, thereby preventing dust from entering from the gap between the two sets of dust covers, thereby preventing dust from affecting the stability of the wire connection, but also preventing the dust cover from scratching the wire body, thereby playing a protective role for the wire, and facilitating the installation and removal of the male plug and the female plug, the specific contents of which are as follows:

[0016] (1) The interface end of the male plug is wrapped by two sets of dust covers to achieve a dustproof effect, thereby preventing the interface end from being directly exposed to the air. The sealing strip bonded to the edge of the upper dust cover fits with the lower dust cover to achieve a sealing effect, thereby preventing dust from entering through the gap between the two sets of dust covers;

[0017] (2) Furthermore, the perforation allows the wire to pass through the male plug, and a protective pad is bonded to the inner wall of the perforation. The provision of the protective pad not only has a sealing effect, but also prevents the dust cover from scratching the wire body, thereby protecting the wire;

[0018] (3) By pressing the pressure rod, the pressure rod moves downward, so that the lower end of the pressure rod squeezes the inclined groove, and the clamping rod slides to the right, so that the left end of the clamping rod is separated from the plug-in block, and then the dust cover can be removed, so as to facilitate replacement or connection of wires;

[0019] (4) The elastic force of the second return spring drives the pressure rod to return to its original position, so that the inner end of the pressure rod no longer contacts the inclined groove.
