Description of reference numerals: the rubber waterproof strip comprises a needle base 100, a boss 101, a slot 102, a contact pin 103, a hole base 200, a convex column 201, a jack 202, a surrounding wall 203, a surrounding cavity 204, an expansion rubber ring 205, an expansion air bag 206, a rubber waterproof strip 3, a fitting groove 4 and a waterproof rubber ring 5.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 3, the waterproof connector in this embodiment includes a needle holder 100 and a hole holder 200, wherein a boss 101 extends from the needle holder 100 in a direction toward the hole holder 200, a slot 102 is formed in the boss 101, a pin 103 extending into the slot 102 is arranged in the needle holder 100, a boss 201 insertable into the slot 102 extends from the hole holder 200 in a direction toward the needle holder 100, a receptacle 202 is arranged in the boss 201, a contact (not shown) matched with the pin 103 is arranged in the receptacle 202, a surrounding wall 203 extends from the hole holder 200 in a direction toward the needle holder 100, a surrounding cavity 204 for the boss 101 to be inserted is surrounded by the surrounding wall 203, and an expansion waterproof structure is arranged in the surrounding cavity 204.

In the practical implementation process, after the needle seat 100 and the hole seat 200 are closed, the boss 101 is inserted into the surrounding cavity 204, and the convex column 201 is inserted into the slot 102, so that the double-layer insertion structure is more favorable for water prevention, and even if water seepage occurs, the expansion waterproof structure can also prevent further seepage.

In this embodiment, the waterproof mechanism that expands includes expansion rubber ring 205 and inflation gasbag 206, the caulking groove has been seted up on the surrounding wall 203, the caulking groove has the opening towards one side of surrounding cavity 204, expansion rubber ring 205 inlays to be established in the caulking groove, inflation gasbag 206 sets up on the lateral wall of hole seat 200 towards needle file 100, inflation gasbag 206 is compressed when hole seat 200 and needle file 100 are closed, inflation gasbag 206 with expansion rubber ring 205 is through hiding the tubule intercommunication in hole seat 200. When the expansion air bag 206 is pressed, gas is pressed into the expansion rubber ring 205, the expansion rubber ring 205 is further expanded, a part of the expansion rubber ring 205 can be exposed out of the opening to be attached to the boss 101, the waterproof effect is achieved, when the needle seat 100 is separated from the hole seat 200, the gas returns to the expansion air bag 206 again, the expansion rubber ring 205 contracts, the needle seat 100 can be conveniently separated from the hole seat 200, the structure is suitable for connectors which need to be repeatedly plugged and unplugged, and in some connectors which do not need to be repeatedly unplugged and unplugged, water-swelling rubber can be used as an expansion waterproof structure.
