Description

Knife type waterproof connector

The present invention relates to a circuit connector, and more particularly to a knife-type waterproof connector that has both easy assembly and effective waterproofing.

Press, when various electronic devices need to connect various circuits such as power or signal, it is common to fix the male connector and the female connector at the two ends of the wire, and then quickly insert the male connector and the female connector through the male connector. An electrical connection is then formed. However, the connector is a part where the overall circuit is relatively prone to failure due to water immersion or moisture. Many electronic devices are used outdoors, in humid or temperature-changing environments, and even in For electronic equipment in a moving state, this type of connector has very high requirements for the waterproof function, and the stability of its electrical connection is also one of the main requirements. Many manufacturers have developed connectors with waterproof functions. The waterproof connectors are often A gasket or washer is added to the connection between the shell and the outer cover to block the gap formed by the connection, so that the outside and the inside of the connector form a basic barrier and waterproof effect, but it is not difficult to find out when looking at the above-mentioned conventional structure. There are still some shortcomings, the main reason is as follows: the gasket or washer is first placed inside the connector, and the outer cover is locked in place. Assembled on the shell, so that the outer cover can cooperate with the shell to clamp the gasket or washer, but when the outer cover is locked, the compression force generated by the applied point and the non-applied point is often different. The gasket or washer is not clamped flat in the connector. The gap caused by the irregularity will reduce the waterproof effect of the connector. Furthermore, even after assembly, the water resistance required by the connector is tested. After long time use or thermal expansion and contraction of the gasket or washer, the gasket or washer may still be caused by factors such as elastic fatigue or shrinkage. The waterproof function is lost, and the assembly method also has many steps. During assembly, the relative position is not easy to fix, which will increase the defective rate and reduce the water resistance. Therefore, it is known that connectors have long been difficult to assemble and have insufficient waterproof effects. point.
