Problems solved by technology

[0003] In order to increase the auxiliary function of the contactor, functional auxiliary modules such as contact auxiliary modules and delay auxiliary modules are usually added. The mounting structure of the auxiliary contacts of the contactor usually includes: 1. The arc extinguishing chamber and the mounting structure are formed separately. An installation cavity is formed in the arc extinguishing chamber, and the hanging structure is inserted and installed in the installation cavity. The disadvantage is that two sets of molds need to be set up to produce the arc extinguishing chamber and the hanging structure respectively, and the production cost is relatively high; Install the arc extinguishing cover and integrally form a hanging structure on the arc extinguishing cover. The disadvantage is that because the arc extinguishing cover is integrally formed with a hanging structure, it is impossible to install contacts that will be exposed to the arc extinguishing chamber on the arc extinguishing cover. The protective cover covered by the support affects the function expansion of the arc extinguishing cover. The contact support is easy to be accidentally touched, and the safety is not high. components, which makes it more troublesome to install the arc extinguishing chamber on the body, affects the arc extinguishing effect of the arc extinguishing chamber, and makes the structure of the arc extinguishing chamber more complicated

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] refer to Figure 1 to Figure 3 As shown, the present invention discloses a contactor auxiliary contact mounting structure, including an arc extinguishing chamber 1, which is installed on the body (not shown in the figure) and integrally formed on the arc extinguishing chamber 1 The hanging piece 2 and the auxiliary contact 3 are installed on the hanging piece 2 .

[0024] The auxiliary contact 3 is installed on the hanger 2, so that the structure of the arc extinguishing chamber 1 is relatively simple, and there is no need to set up a storage chamber for the hanger 2, which saves production costs; at the same time, there is no need to install the hanger 2 on the arc extinguishing cover , to provide convenience for the function expansion of the arc chute.

[0025] In this embodiment, the hanging part 2 is a guide rail groove 21 arra...

Abstract

The invention discloses a hanging installation structure for a contactor auxiliary contact. The hanging installation structure comprises an arc extinguish chamber. The arc extinguish chamber is arranged on a shell, a hanging installation piece is formed in the arc extinguish chamber in an integrate mode, and the auxiliary contact is arranged on the hanging installation piece. The hanging installation structure is simple in structure, saves the production cost, and provides convenience for function extension of an arc extinguish cover.

Description

technical field [0001] The invention relates to the technical field of contactors, in particular to a mounting structure for auxiliary contacts of a contactor. Background technique [0002] A contactor usually includes a body, a static contact, a contact support and a moving contact; the static contact is installed on the body, and the moving contact is installed on the contact support, and the contact support is movably installed in the body. Movement under action makes the moving contact contact or separate from the static contact; usually an arc extinguishing chamber is installed on the body, and one end of the contact support protrudes from the arc extinguishing chamber. [0003] In order to increase the auxiliary function of the contactor, functional auxiliary modules such as contact auxiliary modules and delay auxiliary modules are usually added. The mounting structure of the auxiliary contacts of the contactor usually includes: 1. The arc extinguishing chamber and the...
