Coupler with waterproof function

Abstract

The invention discloses a coupler with a waterproof function. The coupler comprises a plug and a socket, the plug is provided with a pin and a driving rod, the socket is provided with a plugging port, a waterproof component, a driving hole and a driving sliding block, when the plug is not plugged into the socket, the waterproof component shields the plugging port, and only when the plug is plugged into the socket, the driving rod penetrates through the driving hole to abut against the driving sliding block, the driving slide block drives the waterproof component to remove the shielding of the plugging port through the guide structure. By adopting the technical scheme, the structural arrangement of an original waterproof rubber mat is canceled, the problem that water enters the socket due to aging and cracking of the waterproof rubber mat is avoided, and according to the transmission fit among the driving rod, the driving sliding block and the waterproof component, it is ensured to open the plugging port when the plug is plugged into the socket and close the plugging port when the plug is separated from the socket, so that the waterproof component with the design does not influence the normal insertion of the pin and can prevent external moisture from flowing into the socket, and the safety and reliability of the coupler in outdoor use are improved.

Description

technical field [0001] The invention relates to the technical field of couplers, in particular to a coupler with waterproof function. Background technique [0002] The existing coupler includes a plug and a socket, the plug is provided with pins, and the socket includes a socket provided with a jack, a conductive part arranged inside the socket, and a waterproof rubber pad arranged between the conductive part and the jack, and the plug When plugged into the socket, the pins will pass through the socket and the waterproof rubber pad to be electrically connected to the conductive part. This kind of coupler covers the socket by setting a waterproof rubber pad to prevent external moisture from flowing into the socket and avoid conductive parts The water is short-circuited, but when this coupler is used in harsh outdoor environments, the waterproof rubber pad is prone to cracking and aging, causing a gap between the waterproof rubber pad and the jack, resulting in the failure of ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the coupler in the prior art is waterproof through a waterproof rubber pad, and the waterproof rubber pad is easy to age and crack when used in harsh outdoor environments, resulting in the failure of the waterproof function of the coupler, thereby providing a waterproof Effective, waterproof coupler that can be used outdoors for a long time
