Description

Technical Field

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

[0002] Connector, or CONNECTOR, is also called connector, plug and socket. Generally refers to an electrical connector. It is a device that connects two active devices to transmit current or signals. Connectors are a component that electronic engineers often come into contact with. Connectors build a bridge of communication between blocked or isolated circuits in a circuit, thereby allowing current to flow and the circuit to achieve its intended function.

[0003] With the development of the electric power industry, the use scenarios of connectors are becoming more and more extensive, and the requirements for connectors are gradually diversified. Among them, from the perspective of electricity safety, the waterproof effect of the connector has gradually become a factor that users must consider when selecting connectors; Chinese patent announcement number CN 220358409U discloses a waterproof connector, which relates to the field of connector technology. The waterproof connector includes a male connection end, a female connection end, a locking piece and a waterproof cover, the male connection end is provided with a first wire connected thereto; the female connection end is provided with a second wire connected thereto; the locking piece is connected between the male connection end and the female connection end to form a connector structure; the waterproof cover is movably connected to the connector structure;

[0004] The above-mentioned waterproof connector waterproofs the male connection end and the female connection end through a waterproof cover; however, the two ends of the waterproof cover of the above-mentioned waterproof connector are respectively threadedly connected to the male connection end and the female connection end, and the waterproof cover plays a sealing role through the threads at both ends. Although the threads can play a certain sealing role, there are gaps between the threads, so some liquids will still enter the interior of the connector through the gaps in the threads. Therefore, using the threads for sealing results in a poor sealing effect of the connector. Utility Model Content
