Problems solved by technology

However, due to the interference fit structure between the push rod of the push card and the moving spring socket of the moving reed, no matter in the assembly process of the push card and the moving reed or in the service process of the horizontal magnetic circuit relay, There will still be more plastic flakes
[0006] The generated plastic flakes are mainly concentrated in the matching space between the moving reed and the static reed, and the fitting space between the moving reed and the static reed is very sensitive to the presence of plastic flakes. Accumulation will reduce the service stability of the horizontal magnetic circuit relay and affect the service life
[0007] After repeated observation and careful research, the reason why the above two structural forms produce more plastic lint in the matching space between the moving reed and the static reed is that the push rod of the push card and the moving spring insert of the moving reed The contact and fit between the holes is too frequent and the contact and fit time is too long

Abstract

The invention discloses a push card assembly structure of a horizontal relay, which comprises a movable spring plate assembled at one end of a coil frame, and a push card assembled between two ends of the coil frame. The push rod of the movable reed, the movable reed has a movable spring insertion hole that matches the push card, and the push rod at one end of the push card and the corresponding movable spring insertion hole on the movable reed are in an initial state in a ring. To the clearance fit. The invention effectively reduces the contact and mating chance and contact time between the push rod of the push card and the movable spring socket of the movable reed, and does not generate plastic dander in the mating space between the movable reed and the static reed, which is beneficial to ensure The horizontal magnetic circuit relay has stable and long-term service.

Description

technical field [0001] The invention relates to a relay, in particular to a push-card assembly structure of a horizontal magnetic circuit relay. Background technique [0002] The horizontal magnetic circuit relay is a common miniaturized relay structure. It forms a contact assembly structure at one end of the coil frame and an armature assembly structure at the other end. The contact assembly structure is used to assemble the moving reed and the static reed. , the armature assembly structure is used to assemble the armature and the compression spring, push the card to be arranged on the outer side of the coil along the length direction of both ends of the coil frame, and form an up-down corresponding fit with the base of the outer periphery of the coil frame, and push one end of the card to pass the convex The push rod forms a plug fit with the movable spring socket on the movable reed, and the other end forms a plug fit with the armature through the swing slot of the throug...
