Description

Technical Field

[0001] The utility model relates to the technical field of couplers, in particular to a quick-plug wiring coupler. Background Art

[0002] Couplers are common power distribution components. They are conversion devices that use light as a medium to transmit electrical signals. There are many types of photocouplers, including photodiode type, phototransistor type, and photoresistor type. Photocouplers need to be connected to optical fiber wires during use.

[0003] In the prior art, a Chinese patent with a publication number of CN206789675U discloses a coupler, including a housing and a connecting column mounted on the housing, the housing is provided with a cover plate, the cover plate is provided with a first groove, the housing is provided with a second groove, the first groove matches the second groove, a sealing ring is provided in the first groove and the second groove, and the cross section of the sealing ring is a V-shaped structure. The connecting column can connect the output line and the input line, and the sealing ring can improve the sealing performance, so that it can work in a harsh environment without being affected. The sealing ring with a V-shaped structure has a certain elasticity. When sealing, due to its elasticity, it will increase the pressure between the cover body and the housing, thereby improving the sealing effect. The setting of the first groove and the second groove can be positioned when the sealing ring is installed.

[0004] During use, the above-mentioned device needs to connect the wires at the connection column position. The wires are generally fixed by threading. However, the threading method requires the staff to rotate the joint. When encountering installation in a narrow space, it is not convenient for the staff to rotate the joint, which affects the installation operation. Utility Model Content
