Waterproof plug and socket applicable to ships

Abstract

The invention provides a waterproof plug and socket applicable to ships. The waterproof plug and socket applicable to ships comprises a socket, a plug, a first externally connected cable and a second externally connected cable, wherein the first externally connected cable and the second externally connected cable connect the socket and the plug; the first externally connected cable enters from one end, away from a jack, of a socket body and is connected with an electrode clamp spring; the second externally connected cable enters from one end, away from a plug-in piece, of a plug body and is connected with the plug-in piece. The waterproof plug and socket applicable to ships further comprises a thread waterproof structure composed of a first thread ring, a second thread ring and a thread base; flanges used for limiting the thread rings are made of thermoplastic elastomer materials and are formed on the socket body or the plug board in a secondary injection molding mode, at the same time, the thread rings are made of hard polycarbonate engineering materials, and the outer diameter of the position where the flanges and the thread rings are combined after injection molding is greater than the inner diameter of the thread rings. By means of the structural design, the thread rings can be detached from the flanges conveniently, and the limit intensity of the flanges on the thread rings is also ensured.

Description

technical field [0001] The invention relates to the field of plug sockets, in particular to a waterproof plug socket suitable for ships. Background technique [0002] The power plug and socket device is an indispensable electronic accessory in industrial production and daily necessities, which includes a plug and a matching socket. Traditional plugs and sockets respectively include electrode inserts and electrode clip springs, and the electrode clip springs are usually formed by bending a piece of copper. When the plug is inserted into the socket, the electrode inserts of the plug are inserted into the electrode clip springs of the socket, and the electrical connection and locking between the plug and the socket are realized by the contact action between the electrode inserts and the electrode clip springs. Although the plugs and sockets in the prior art are relatively tightly combined, when they are used on ships with relatively high waterproof performance requirements, on...
