Description

Multi-point synchronous plug-in switchgear

The utility model relates to a switch device, in particular to a multi-point synchronous plug-in switch device used in switches of relatively large power electric appliances such as relays.

At present, the main structure of the switchgear in the known relay is: a group of double-contact contact sheets are installed on the movable plug seat, and a group of wiring contact posts are installed on the socket socket of the relay body.

This kind of contact-type on-off current switch structure has problems such as poor contact and arcing hazards, which shortens the service life of the relay and also limits the switch to pass a large current.

The purpose of the utility model is to provide a multi-point synchronous plug-in switch device, which not only has good contact and small arcing, but also has high reliability and long service life.

The purpose of this utility model is achieved in this way: a multi-point synchronous plug-in switch device, which is installed in the slot hole of the comb-shaped insulating movable plug seat (2) on the relay (1) Body double plugs (7), a channel-shaped conjoined double plug (7) is respectively installed at the two ends of each slot; a group of bottleneck-shaped wiring sockets (6 ), the center is provided with a set of bottleneck-shaped conjoined double sockets (5). The wiring socket (6), the one-piece double socket (5) and the socket seat (3) are clamped and positioned by the insulating bead (4) passing therethrough. When the relay (1) is energized, the channel steel-shaped conjoined double plug (7) fixed on the movable plug seat (2) on the elevator iron is synchronously inserted into the bottleneck-shaped wiring socket (6) and the bottleneck-shaped conjoined double plug In the cover (5), the switch is closed. Otherwise, the shape is disconnected.

The design principle of the switch is: the multi-point synchronous plug-in and current-off method can ensure that the switch device has sufficient conductive contact area and the lowest contact resistance, as well as the smallest switch stroke. The switching speed is improved, the arcing time is shortened, and the phenomenon of poor contact is overcome. Therefore, the rated power index of the relay can be greatly improved under a small switch volume.

Due to the adoption of the above scheme, the switching device adopts a multi-point synchronous plug-in current-on-off structure, which has the advantages of good contact, small arc, high reliability, convenient installation and use, and simple structure, which greatly improves the efficiency of relays and other electrical switches. The service life and power rating of the device.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.
