Embodiment Construction

[0022] refer to Figure 1 ~ Figure 3 , this new railway signal relay contact system is a C-type elastic DC relay, the coil 3 is wound on the core column 2, and the yoke 5 is installed on the base 6. The armature 1 is connected to the insulating pull rod 9 . The moving reed 8 and the static reed 9 are pressed into the base, the static contact is divided into a front contact and a rear contact, the insulating pull rod connects the moving reed 8 and the armature 1, and the insulating pull rod 9 connects with the moving reed 8 through the groove set on the top. Pull out together, rigid stop sheet 10 and elastic pressure sheet 9 are installed on static spring sheet 7 both sides, and the bottom end is pressed in the base.

[0023] After the armature moves, the static reed 7 with the front contact is disconnected from the moving contact under the obstruction of the rigid stopper 10; The moving contacts are tightly combined.

[0024] Working process of the present invention.

Abstract

The invention discloses a novel railway signal relay contact system, which is characterized by comprising moving reeds, static reeds, a pull rod, stopping sheets and pressing sheets, wherein the moving reeds and the static reeds are pressed in a substrate; a static contact is divided into a front joint and a rear joint; the pull rod is connected with the moving reeds and an armature and are fit with the moving reeds via grooves arranged at the top end; and each stopping sheet and each pressing sheet are arranged at two sides of each static reed. The stopping sheets are used for limiting the positions of the static reeds, a limiting frame is replaced, the structure is simple, mounting is easy, and the production efficiency is improved; after the moving contact and the static contact are closed, the pressing sheets apply pressure to the static reeds to enable the moving contact and the static contact to be tightly closed, contact resistance is reduced, and conductive performance is improved.

Description

technical field [0001] The invention relates to an elastic railway signal relay, in particular to an elastic railway signal relay with a new contact system, which belongs to the technical field of low-voltage electrical equipment. Background technique [0002] The existing elastic railway signal relay contact system generally adopts the structure of pull rod+limiting frame or pull rod+block. The former has high technical requirements and is difficult to install; the latter has poor anti-vibration performance and low reliability. Moreover, the action of the two is not sensitive, the return coefficient is low, and the anti-vibration and anti-shock ability is weak. With the rapid development of my country's railway industry, higher requirements are put forward for railway signal relays. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, aiming at the defects in the existing railway signal relay ...
