Anti-loose elastic welding cable quick connect device

Abstract

The invention relates to a connecting device for welding cables. The rapid connecting device is mainly applied to connection between welding cables and welding devices or applied to connection between welding cables. The anti-loosening type elastic rapid connecting device comprises a male plug and a female socket, wherein a movable clamping head under the action of a spring is arranged on the male plug. The male plug and the female socket are clamped when the clamping head which has spring tension and is arranged on the male plug is connected with and clamped on a clamping groove in the female socket in an elastic mode. Under the normal working condition, the clamping head of the male plug can not easily slip off the clamping groove which has the taper and is formed in the female socket, illusory connection or loosening can not occur even when the clamping head of the male plug slides due to a certain external cause, the old problem which has puzzled a user for a long time is solved on the promise that the traditional use method of the user does not need to be changed, the problems of universality, illusory connection and loosening are effectively solved, reliability and safety can be remarkably improved, and the technical defects are effectively overcome.

Description

technical field [0001] The invention relates to a welding cable connection device, in particular to a loose-proof elastic welding cable fast connection device, which is mainly used in the fast connection device for connecting welding cables and welding equipment or welding cables. Background technique [0002] At present, the most commonly used quick connection schemes for welding cables and welding cables or welding cables and welding equipment in the market are the connection between a male plug and a female plug or female socket (hereinafter collectively referred to as the female socket). The protruding movable clip enters the card slot through the guide groove of the female socket, and the male plug is rotated so that the clip on the male plug is pushed inward along the tapered slot on the female socket, so that the end face of the male plug and the end face of the female socket are rotated Tight contact, because the male plug and the female socket are all one-piece fixe...

Problems solved by technology

[0002] At present, the most commonly used quick connection schemes for welding cables and welding cables or welding cables and welding equipment in the market are the connection between a male plug and a female plug or female socket (hereinafter collectively referred to as the female socket). The protruding movable clip enters the card slot through the guide groove of the female socket, and the male plug is rotated so that the clip on the male plug is pushed inward along the tapered slot on the female socket, so that the end face of the male plug and the end face of the female socket are rotated Tight contact, because the male plug and the female socket are all one-piece fixed structure, there is no uniform standard size between the card head and the card slot produced by many manufacturers on the market, making it difficult for various male plugs and female sockets to be universal , has brought great inconvenience to users. Even if a qualified product produced by a manufacturer is a fixed structure, there is only an operating stroke of 1-2mm between tightening and loosening during use. In actual production work, due to Due to many factors such as handling, vibration, collision, dirt on the male plug and female socket, thermal expansion and contraction, etc., it is very easy for the male plug clip to slide naturally from the tapered groove of the female socket, causing false connection or loosening. At this time, the male plug and the female socket will generate heat. In the light case, electric sparks will be generated to burn the male plug and the female plug.
