Description

Sealing assembly, connector and connector assembly

Technical Field

The present invention relates to a seal assembly, a connector including the seal assembly and a connector assembly including the connector.

Background

In the prior art, two connectors capable of mating are generally used to realize quick connection of a cable to a circuit board. One connector is connected to the cable and the other connector (called a mating connector) is connected to the circuit board. The connection of the cable to the circuit board can be achieved by mating the two connectors.

In the prior art, in order to achieve waterproof sealing, an elastic sealing sleeve is usually sleeved on the cable, and when the cable is plugged into a cable jack of the connector, the elastic sealing sleeve can seal the cable jack on the connector. However, when the cable is not plugged into the cable insertion hole, contaminants such as dust from the outside may enter the inside of the connector through the cable insertion hole. In order to prevent external dust from entering the inside of the connector through the vacant cable insertion hole, in the prior art, it is generally necessary to insert a rod-shaped plug in the vacant cable insertion hole to close the cable insertion hole.

However, in the prior art, the rod-shaped plug has no waterproof function, and the rod-shaped plug interferes with the mating terminal in the mating connector, so that the mating terminal in the mating connector needs to be removed in advance, and the operation is very inconvenient.
