Auxiliary contact with indication function, and contactor

Abstract

The invention relates to an auxiliary contact with an indication function, and a contactor. The auxiliary contact comprises a shell, a contact module and an indication module, one end of the contact module stretches out from the shell to be connected with a linkage hole of a contactor main body, an indication hole is formed in a top end of the shell, with the suction or release of the contactor main body, the contactor main body drives the drives the indication module to move below the indication hole through the contact module, so as to display different indication states at the indication hole, the indication module comprises two guide plates below an indication plate, a guide groove is formed in each guide plate, the contact module comprises a contact support and is provided with a double-end slide block, and the two ends of the double-end slide block are respectively embedded in the guide grooves of the two guide plates. Compared with the prior art, the auxiliary contact provided by the invention has the indication function, so that the operation and maintenance personnel can see switch state indication maximally and can clearly and accurately observe and judge the state of a switch main body and an auxiliary module; the scheme design is simple, and the assembly is easy; and the function is practical, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of a contactor, in particular to an auxiliary contact with an indication function and a contactor. Background technique [0002] The side-mounted auxiliary contact is a side-mounted auxiliary contact module for AC contactors. It is installed on both sides of the switch body to help transmit the operating status signal of the switch or form an electrical interlock between the switches. For personal safety, the operation and maintenance personnel require the visualization of the action state of the switch, and the switch is required to have a visual, reliable, and clear function of indicating the closing and opening states of each contact of the switch. However, some switch bodies and auxiliary modules currently on the market cannot satisfactorily complete the above-mentioned indicating functions. Under such working conditions, the user cannot intuitively judge the electromagnetic switch state of the contacto...

Problems solved by technology

However, some switch bodies and auxiliary modules currently on the market cannot satisfactorily complete the above-mentioned indicating functions. Under such working conditions, the user cannot intuitively judge the electromagnetic switch status of the contactor body according to the contactor body, and the existing side-mounted auxiliary contacts do not have an indication function, such as figure 1 As shown, it is also impossible to indicate the electromagnetic switch state of the contactor body according to the switch state of the side-mounted auxiliary contact
