Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a waterproof connector. Background Art

[0002] Connectors are widely used in the field of electronics. They are used to achieve reliable connections between electronic terminal devices and between electronic terminal devices and power supplies. The performance of the connector directly affects whether the entire electronic device works properly. Charging and signal transmission are basically essential functions of electronic products, which are often achieved through connector connections. At present, a large number of electronic products require waterproof performance, so connectors must have waterproof functions. However, ordinary socket connectors are not designed to be waterproof. During use, water or other acidic and alkaline liquids intrude, which will cause the conductive pins to corrode and oxidize. When the male and female terminals are plugged in, the contact resistance becomes larger, which is prone to high heat and fire abnormalities, posing a greater safety hazard. Utility Model Content

[0003] The technical problem to be solved by the utility model is that, in view of the above-mentioned defects of the prior art, a waterproof connector is provided, which realizes waterproofing by adding an outer waterproof silicone ring and an inner waterproof silicone ring to cooperate with each other. When the male and female terminals are plugged in, the outer waterproof silicone ring and the inner waterproof silicone ring can prevent water or other foreign matter from entering the plug-in cavity, thereby improving the safety protection effect and making it safer to use.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A waterproof connector comprises a connector body, a plurality of connection terminals are arranged on the connector body, a plug-in cavity is opened on the inner side of the connector body, an inner waterproof silicone ring is arranged at the opening of the plug-in cavity, an outer waterproof silicone ring is arranged at the front end edge of the connector body, a water-proof groove is formed between the outer waterproof silicone ring and the inner waterproof silicone ring, and mutually symmetrical clamping buckles are arranged on the outer waterproof silicone ring.

[0006] Preferably, one end of the wiring terminal is located in the plug-in cavity, and the other end of the wiring terminal passes through the connector body to achieve electrical conduction.

[0007] Preferably, the clamping buckle includes a first clamping buckle and a second clamping buckle, and the first clamping buckle and the second clamping buckle are symmetrically arranged at the left and right ends of the outer waterproof silicone ring, which is conducive to clamping the plug and improving the connection stability.

[0008] Preferably, a clamping protrusion is disposed on the inner side of the first clamping buckle and the second clamping buckle.

[0009] Preferably, the outer waterproof silicone ring and the inner waterproof silicone ring are both made of silicone material.

[0010] Preferably, the height of the inner waterproof silicone ring is lower than that of the outer waterproof silicone ring, and the outer waterproof silicone ring is provided with a plurality of circular through holes.

[0011] By adopting the above technical scheme, a waterproof connector provided by the utility model has the following beneficial effects: a plurality of wiring terminals are arranged on the connector body in the waterproof connector, a plug-in cavity is opened on the inner side of the connector body, an inner waterproof silicone ring is arranged at the opening of the plug-in cavity, an outer waterproof silicone ring is arranged at the front end edge of the connector body, a water-proof groove is formed between the outer waterproof silicone ring and the inner waterproof silicone ring, and mutually symmetrical clamping buckles are arranged on the outer waterproof silicone ring. Waterproofing is achieved by adding an outer waterproof silicone ring and an inner waterproof silicone ring to cooperate with each other. When the male and female terminals are plugged in, the outer waterproof silicone ring and the inner waterproof silicone ring can prevent water or other foreign matter from entering the plug-in cavity. At the same time, the clamping buckle further clamps the plug, thereby improving the connection stability of the male and female terminals, enhancing the safety protection effect, and being safer to use.
