Technical scheme

In order to realize the technical purpose, the utility model provides an automatic change-over switch's line concentration device, its characterized in that: the plug comprises an end cover, a plurality of sockets, a plurality of plugs and a transition connector, wherein the sockets are correspondingly arranged in a plurality of mounting grooves formed in the transition connector, one ends of the plugs are correspondingly inserted into the slots formed in the sockets, the other ends of the plugs are used for being connected with an accessory module, and the end cover is arranged on the transition connector and covers the mounting grooves.

Further, the line concentration device is installed on the front face of the switch base.

Further, the installation grooves are arranged in at least one layer side by side.

Further, the mounting slots and the end caps together limit displacement of the sockets.

Further, the end caps are fixedly mounted at the top end or/and the bottom end of the transition connector.

Further, the accessory module is a motor or a shunt electromagnet or a closing electromagnet or an auxiliary switch.

Advantageous effects

The utility model provides a pair of automatic change over switch's line concentration device simplifies the wiring step, makes things convenient for pencil installation location, reduces the space of pencil and occupies, guarantees that the pencil is neat pleasing to the eye, can make things convenient for the dismouting of annex simultaneously, realizes the common power side and the sharing of annexs such as reserve power supply side shunt, closure, motor and auxiliary switch. The whole line concentration device is flexible to install, simple and compact in structure, and capable of guaranteeing the sharing performance of accessories such as shunt excitation, closing, motors and auxiliary switches on the two sides of the normal/standby power supply, gathering all wiring harnesses together, guaranteeing wiring convenience and optimizing the layout of a whole product.
