Abstract: A socket of an optical controller includes: a base having an electrical plughole and a pin accommodation groove; a mounting seat having a wire trough and a pin mounting groove; a metal pin, arranged in a cavity formed by the pin accommodation groove and the pin mounting groove; a contact piece, connected with an external wire, and comprising a wiring pin, a positioning pin and a contact surface that has an arc shape matching with that of the base; a groove, arranged at a joint corner of the wiring pin and the positioning pin with the contact surface; the wiring pin and the positioning pin are arranged on both sides of the contact surface; and the wiring pin and the positioning pin are bent 90-degree on an inner side of the groove. Waterproofing is also disclosed.

Abstract: The invention relates to a photo-control receptacle, which comprises a base, having a power jack formed on one side and a pin holding groove formed on the other side thereof and communicated with the power jack; a mounting base, connected with the base through a connecting structure, having a plurality of pin mounting grooves arranged on one end and cable grooves arranged on the other end thereof and communicated with the pin mounting grooves; wherein, each of the pin mounting grooves has a metal pin arranged therein, which is further arranged to extend into the pin holding groove, the cable groove has a cable arranged therein and connected with the metal pin. The photo-control receptacle of the utility model achieves the tool-free installation, the assembly process is simple and saves time and labor. In addition, according to the actual situation, the orientation of the photo-control device can be adjusted by changing the relative position of the base and the mounting base.
