Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electrical connection assembly production, and particularly relates to a bent push-pull self-locking sealing structure for electricity. BACKGROUND

[0002] In the prior art, the sealing degree of the sealing structure at the cable connection is relatively low. During the cable connection process, air is easy to enter the inside or outside of the cable through the gap between the pins, which will cause the following problems. First, the entry of air may affect the reliability and stability of the cable connection, and further cause instability or errors of signal transmission, thereby increasing the probability of failure. Second, the physical presence of air in the cable may also cause damage to the insulating layer of the cable, thereby causing further safety hazards.

[0003] In the prior art, the cable connection is usually directly sealed by an insulating layer. On the one hand, due to the gap between the pins during the assembly arrangement process, air can still enter the inside of the cable through the gap between the pins after the insulating layer is solidified, thereby reducing the signal transmission stability of the cable and the service life of the cable. On the other hand, the insulating layer covering structure is not convenient for subsequent cable maintenance. During the cable maintenance process, the insulating layer needs to be cut open for maintenance, thereby significantly reducing the maintenance convenience. Therefore, there is an urgent need to make improvements. CONTENT OF THE UTILITY MODEL

A user can drive the driving end to move towards or away from the pin assembly, so as to drive the fastening sealing assembly to stretch or contract, thereby discharging the air in the shell main body to the outside of the shell main body.
