BACKGROUND

The electrical connector is a device used for fixing a lamp to a position and making the lamp contacts connected to the power source, reasonable use of the electrical connector helps to regularize wiring and extend the electrical line, for some objects that require rendering of light, such as Christmas trees, which will be mounted with a lot of LED parts for decoration, if using traditional wiring it will cause trouble in wiring, and electrical lines and LED parts are mostly in fixed state, when it is necessary to increase the number of LED parts additional wiring is needed, which is difficult to extend, and is not flexible to design according to the requirements which affects the overall appearance of the Christmas tree. For these reasons, a connector for Christmas trees has been developed on the market, including a male annular socket and a female annular socket, the male socket and the female socket are both configured to surround the trunk or the branch of the Christmas tree and are connected to each other for electrical connection, and the male socket and the female socket are respectively provided with a power cord so that the male socket can be electrically connected to the total power source (or LED light emitting parts) and the LED parts (or the total power source) so that it is flexible for configuration of a number of the above-mentioned connectors for the Christmas tree. However, the applicant found that the structure of the electrical connection between the male socket and the female socket, which is only accomplished via a piece of metal on the male socket and a piece of metal on the female socket to contact for electrical connection, is simple, after a long time of use the electrical connection between the two metals is easy to become poor contact and unstable, causing the LED light-emitting parts can not light up, and as the number of connectors mounted on the Christmas tree is also relatively large, it is very difficult to troubleshoot and solve the problem of poor contact, for these reasons, the applicant concluded that an electrical connector which reinforces the structure of the electrical connection is necessary for a good electrical connection to prevent the LED light-emitting parts from being unable to light up and to avoid subsequent difficulties in troubleshooting and solving problems.
