Abstract

The invention relates to an improved coupler. The improved coupler comprises a coupler body and an insertion component. The insertion component comprises a socket-and-spigot joint and a press fit shaft sleeve. The socket-and-spigot joint is of a cylindrical structure. Two insertion channels are formed in the socket-and-spigot joint. The inner wall of each insertion channel is provided with a metal conductive layer. One end of the socket-and-spigot joint is fixedly connected with the coupler body and the other end of the socket-and-spigot joint is provided with an inwards recessed clamping groove. The clamping groove is of a conical structure. The press fit shaft sleeve is of a hollow cylindrical structure and is arranged outside the socket-and-spigot joint in a sleeving mode. The press fit shaft sleeve is made of elastic rubber. The press fit shaft sleeve is in interference fit with the socket-and-spigot joint. The shape of the section of the press fit shaft sleeve is triangular. An annular buffering cavity is formed in the press fit shaft sleeve in the circumferential direction. The shape of the section of the buffering cavity is identical with that of the section of the press fit shaft sleeve. According to the improved coupler, insertion is firm, disengagement is not likely to happen, the good waterproof effect is achieved, the improved coupler can be adapted to various severe environmental conditions, and the service life is prolonged.

Description

technical field [0001] The invention relates to a coupler, in particular to a coupler for garden lighting. Background technique [0002] Couplers are widely used in technical fields such as microwave communication, electronic countermeasures and radar, and product reliability, stability and high cost performance are very important. With the promotion of the scope of application, more and more coupler products work in some harsh environments, such as humid and warm southern weather, the product will reduce its service life due to the impact of the environment, so how to improve the product To cope with the impact of harsh environments, prolonging its working life has become an urgent technical problem to be solved. Most of the products currently on the market cannot be used outdoors, because the interior of the products does not solve the problem of waterproofing. If the product is used in a humid and warm environment for a long time, it will be damaged, which greatly reduc...
