Description

Technical Field

[0001] The utility model belongs to the technical field of electric connectors, and in particular relates to an electric connector. Background Art

[0002] The wiring method of LED lights is generally to fix the connecting wires through a junction box with screws, or to bond the connecting wires with waterproof tape to achieve electrical connection between the LED lights and the external power supply. However, this wiring method makes the wires easy to loosen and the installation is cumbersome.

[0003] In order to solve the above problems, detachable electrical connectors have appeared on the market. For example, the utility model named "A detachable light strip waterproof connector assembly and LED light strip" disclosed with announcement number CN206302001U is a Chinese patent. The detachable light strip waterproof connector assembly includes a middle connector and an end cover. The middle connector is a column with a hollow accommodating cavity inside and an external thread outside. Electrode pins are arranged at both ends of the hollow accommodating cavity. An annular groove is formed on the inner wall at both ends of the hollow accommodating cavity. A sealing ring is installed in the annular groove. A buckle is connected to the upper end of the end cover. The end of the end cover protrudes outward near the middle connector to form a sealing part. A locking nut is sleeved on the outer end of the end cover, and the other end of the locking nut is screwed on the outer end of the middle connector. When the locking nut is screwed to the middle connector, the sealing part is pushed to drive the end of the end cover to squeeze the sealing rings located at both ends of the hollow accommodating cavity of the middle connector. It has a simple structure, low cost, high reliability, easy installation and disassembly, and can be extended and connected with other light strips. However, the connector assembly can only realize the electrical connection between the light strip and the power plug, and cannot realize the color temperature control of the light strip.
