Abstract
The utility model relates to an auxiliary switch which belongs to the field of an electric apparatus switch. The utility model comprises an insulating supporting frame and a static contacting head. The auxiliary switch is characterized in that the position for placing the static contacting head on the insulating supporting frame is provided with a positioning column integrated with the insulating supporting frame, and the position of the other surface of the insulating supporting frame corresponding to the positioning column is provided with a positioning column hole. The static contacting head is provided with a positioning hole corresponding to the positioning column, and the positioning column is plugged in the positioning hole. The auxiliary switch has the advantages of simple structure, reasonable design and low cost and solves the problem that the auxiliary switch is easy to move in the using process. The reliable performance of the auxiliary switch is improved.
Description
A kind of auxiliary switch belongs to the electric equipment field of switches.
Electric equipment needs multiple auxiliary switch, the present auxiliary switch F10 that uses, the mode of connection is that fixed contact is pegged graft, there is not location and installation between insulating support and the fixed contact, therefore in the grafting process, because the external force effect, stationary contact closes to change hands to give birth to and rotates and play, cause that auxiliary switch breaks down, and normally moves and influence electric equipment.
The purpose of this utility model is to provide a kind of auxiliary switch that has positioner, has guaranteed fixedlying positioning between fixed contact and insulating support, insulating support and the insulating support, avoids the fault that is caused by the fixed contact play.
Auxiliary switch comprises insulating support, fixed contact, and the position that it is characterized in that laying on the insulating support fixed contact is provided with the reference column with the insulating support one, and the another side of its insulating support and reference column correspondence position are provided with the reference column hole.Have on the fixed contact and the reference column corresponding positioning hole, the two plugs together.
The utility model is simple in structure, and is reasonable in design, do not increase cost again, solved the problem of easy play in the auxiliary switch use, improved the unfailing performance of auxiliary switch.
Fig. 1 auxiliary switch is laid the schematic diagram of fixed contact one side
Fig. 2 auxiliary switch another side schematic diagram
Example:
Auxiliary switch is by insulating support 1, fixed contact 2 is formed, reference column 3 with its one is arranged on 4 angles of insulating support 1 one side, have the location hole 4 corresponding on the fixed contact 2 with reference column 3 shapes, the position of the corresponding reference column 3 of the another side of insulating support 1 is provided with reference column hole 5, during assembling, the location hole 4 of fixed contact 2 is enclosed within on the reference column 3 of insulating support 1, make it the location, the one side of a plurality of insulating support 1 band reference columns 3 plugs together combination with the one side in band reference column hole 5, in use, fixed contact can not guarantee the operate as normal of auxiliary switch because of grafting play or rotation.
Claims (2)
