Mount 100 is the main body portion of the receptacle, providing the mounting base for ferrule assembly 200 and face cover 300. The mounting grooves 110 are used for mounting the plug bush assemblies 200, and are arranged on the mounting base 100 at intervals. The spacers 120 are disposed between the adjacent mounting grooves 110 with their tops protruding from the top ends of the mounting grooves 110. On the one hand, the spacer 120 is used as a physical barrier between two adjacent plug bush assemblies 200, so that the shortest path between the two plug bush assemblies is effectively increased, namely, the creepage distance between the two adjacent plug bush assemblies 200 is increased, the creepage phenomenon is reduced, and accordingly the electrical safety of the socket is improved, on the other hand, the spacer 120 can be in snap connection with the slot 320 on the face cover 300, positioning installation of the face cover 300 is facilitated, connection stability between the face cover 300 and the mounting seat 100 is improved, and in addition, the protruding portion of the spacer 120 can be used as an isolation barrier between the mounting seat 100 and the face cover 300, and electrical short circuit between the adjacent plug bush assemblies 200, between the plug bush 210 and the face cover 300 is avoided, and protection of the socket and electric equipment is facilitated. It will be appreciated that the spacer 120 is made of a material having high insulating properties, such as ceramic, plastic, etc. The material with high insulating property can effectively prevent current from passing through, and can maintain a stable insulating state even in the presence of a voltage difference.

The ferrule assembly 200 includes a ferrule 210 and pins 220, the pins 220 for connection to a circuit and for transferring electrical power to the ferrule 210, and the ferrule 210 for contacting a plug and transmitting electrical power.

Specifically, the mounting groove 110 includes a first mounting groove and a second mounting groove, and in the arrangement direction of the mounting groove 110, the second mounting groove is offset with respect to the first mounting groove, so that the first mounting groove and the second mounting groove are staggered on the mounting seat 100, and thus, a part of space is yielded in the offset direction of the second mounting groove for mounting the pins 220, so that the electric equipment can better utilize the space of the second mounting groove away from the offset side, and other devices are arranged at the position of the second mounting groove.

In the related art, some electric devices mount the socket in the center of the device housing 400, but the positions of the two sides of the device housing 400 are too narrow, and the space of the two sides is not enough to be utilized. The staggered arrangement of the embodiment can reserve space for electric equipment, and compared with the parallel arrangement, the layout of all the components in the equipment shell 400 of the electric equipment can be optimized, and the space utilization efficiency of the electric equipment is improved.
