TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical connectors, in particular to a T-shaped connector base convenient to disassemble and assemble. BACKGROUND

[0002] A connector is a common wire connector, widely used in low-voltage circuits, and its basic structure consists of two parts, a pin and a socket. According to the requirements of the circuit, the pins are evenly distributed in the base of the plug, while the sockets are evenly distributed in the base of the opposite plug. The socket is usually provided with an opening for receiving the pin and fastening it. The pin and the socket are usually made of metal material, and the electrical connection is achieved by inserting and fitting. After the pin is inserted into the socket, the metal contact surfaces of the two are tightly bonded to form a conductive path, thereby realizing the transmission of current or signal. Connectors are also divided into many types, among which the T-shaped connector is a connector used to branch one or more branches from the main line. Its appearance is similar to the letter "T". It is usually used in electrical, communication or data transmission systems to realize the distribution of signals or currents. It usually has one input port and two output ports to facilitate the distribution of signals or the expansion of lines. Each port uses plug and socket insertion to connect the lines.
