Description

Technical Field

[0001] This utility model relates to connectors for sensor modules, and more particularly to connectors for sensor modules that facilitate the assembly of sensor modules and prevent water or moisture from entering the sensor modules. Background Technology

[0002] In sensors such as photoelectric sensors or image sensors, a circuit board constituting a control unit is housed within the sensor housing. A cable passes through the sensor housing to provide power from outside the sensor housing to the circuit board and to transmit signals from the sensor or signals processed by the circuit board to the outside. US Patent US11744025B2 (Patent Document 1) discloses a light sensor that allows for simple cable mounting to a circuit board.

[0003] In Patent Document 1, the cable is pre-soldered to one end of the FPC, and the other end of the FPC is inserted into a connector mounted on a circuit board. The cable is then watertightly engaged with the sensor housing via a screw-in connector integrally formed near its end. In Patent Document 1, the mating of the FPC with the connector and the engagement of the cable with the sensor housing require manual assembly. Therefore, the configuration disclosed in Patent Document 1 is not conducive to automated production and makes it difficult to increase production speed. Furthermore, the FPC is a high-priced component, resulting in increased cost of the sensor module. Utility Model Content
