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 state 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

Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0035] Such as figure 2 As shown, this embodiment provides an auxiliary contact with indicating function, which includes a housing 1 , a contact module 2 and an indicating module 3 . Both the indicator module 3 and the contact module 2 are installed in the housing 1, and one end of the contact module 2 protrudes out of the housing 1 to connect to the linkage hole of the contactor body; the top of the housing 1 is provided with an indicator hole 13. Pulling in or releasing, the contactor body drives the indicating module 3 to move under the indicating hole 13 through the contact modu...

Abstract

The invention relates to an auxiliary contact with an indication function, and a contactor. The auxiliary contact is installed on a side wall of one side of a contactor main body, and comprises a shell, a contact module and an indication module, the indication module and the contact module are both installed in the shell, one end of the contact module stretches out from the shell to be connected with a linkage hole of the 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 linkage hole of the contactor main body 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. 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; through simple cooperation of a small number of parts, the vertical displacement is converted into horizontal displacement to realize the indication function, 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 status of the contact...
