Problems solved by technology

[0003] 1. When the armature is released, the contact support is reset under the action of the reaction force spring, which makes the contact support collide with the body, and because the contact support is relatively fragile, the contact support is easily damaged
[0004] Second, when the contact support moves under the action of the electromagnet, the side of the contact support will rub against the body, and the friction is surface-to-surface friction, which makes the contact support and the body wear more
[0005] Third, in order to prevent the fixing pin from falling off, it is often necessary to design a more complicated fixing structure to limit the fixing pin, and the structure is complicated and the cost is increased

Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] refer to Figure 1 to Figure 7 As shown, a contactor disclosed by the present invention reduces friction buffering structure, which includes a contact support 1, and a buffer member 2 is installed on the collision surface where the contact support 1 contacts the body (not shown in the figure), and the buffer member An elastic buffer surface 20 is formed on the 2, and when the contact support 1 collides with the body, due to the elastic buffer effect of the elastic buffer surface 20, the contact support 1 is less stressed and is not easily damaged, saving the cost of use.

[0040] The contact support 1 installs the armature 4 through the fixed pin 3, specifically, a pin hole 11 is set on the contact support 1, such as Figure 5 As shown, the armature 4 is correspondingly provided with pin holes 41 , and then the fixing pin 3 is sequent...

Abstract

The invention discloses a friction reducing and buffering structure for a contactor. The structure comprises a contact support, a buffering piece is arranged on a collision face, the contact support makes contact with a shell on the collision face, and an elastic buffering face is formed on the buffering piece. The friction reducing and buffering structure can buffer the collision between the contact support and the shell, and reduce the friction between the contact support and the shell.

Description

technical field [0001] The invention relates to the technical field of contactors, in particular to a friction-reducing buffer structure of a contactor. Background technique [0002] In the prior art, 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 , moves under the action of the electromagnet, so that the moving contact contacts or separates from the static contact; in order to install the armature, pin holes are usually provided on the contact support, and pin holes are correspondingly provided on the armature, and then, through the fixed pins in turn Insert the armature into the two pin holes and install the armature on the contact support. The disadvantages are: [0003] First, when the armature is released, the contact support resets under the action of the reacti...
