Abstract
The utility model discloses a composite static contact piece, which comprises a static contact piece main body. The composite static contact piece is characterized in that: bumps facing the direction of a movable contact are integrally arranged at positions opposite to the movable contact in a relay on the static contact piece main body; and a composite layer is compounded on each bump. The composite static contact piece has the advantages that: the bumps facing the direction of the movable contact are integrally arranged at the positions opposite to the movable contact in the relay on the static contact piece main body, and a composite layer is compounded on each bump to replace static contacts on the conventional static contact piece, and the static contacts are integrally arranged on the static contact piece, and can be directly inserted into the relay in assembly, so that the composite static contact piece is time-saving and labor-saving, and the production efficiency of the relay is improved; and moreover, the consistency of the composite static contact piece is greatly higher than that of the conventional static contact piece, so that the assembly accuracy of the relay is improved, each electrical property of the relay is optimized, and the service life of the relay can be greatly prolonged.
Description
Technical field
The utility model relates to a kind of building block of relay, relates in particular to the quiet contact chip of a kind of combined type.
Background technology
Relay is a kind of automatic electric switch, and when certain energy of the input that gives a regulation and when keeping sufficiently long time, its controlled circuit that just can automatically switch makes it to produce a transition.When input variable was reduced to a certain degree and keep enough long-time, it returned to initial condition again, and controlled circuit also steps to original state.This transition and the adhesive and the release that recover directly to show relay contact are so the assembly precision of relay contact directly has influence on each item electric property of relay.In addition, along with the continuous lifting of labor cost, improve automatization level and be current relay manufacturer one big hot thing, and the degree of consistency of relay parts directly affects the automation adaptability of relay assembling.At present; Fixed contact adopts the mode and the quiet contact chip of riveted joint or welding to link usually; On the relay production line, need to be equipped with special equipment and personnel and to accomplish this operation, and the riveted joint of fixed contact or welding quality also are big Quality Control points of relay production.
Summary of the invention
But the utility model technical problem to be solved is a kind of production line assembly process of simplifying relay, improves the assembly precision of relay, again applicable to the quiet contact chip of the combined type of automated production.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the quiet contact chip of a kind of combined type; Comprise quiet contact chip main body; On the described quiet contact chip main body in the corresponding relay position of moving contact be wholely set convexity towards the moving contact direction, be compounded with composite bed on the described convexity.
The material of described composite bed can be silver, silver alloy, gold, billon, palladium, palldium alloy, platinum or platinum alloy or the like.
Compared with prior art; The utility model has the advantages that the position owing to moving contact in the corresponding relay on the quiet contact chip main body is wholely set the convexity towards the moving contact direction, and on convexity, be compounded with composite bed, substituted the fixed contact on traditional quiet contact chip; Fixed contact is wholely set on quiet contact chip; Can directly be inserted in the relay during assembling, save time, the saving of labor, improve the production efficiency of relay; And the consistency of the quiet contact chip of this combined type is superior to traditional quiet contact chip greatly, and the assembly precision that has improved relay has been optimized each item electric property of relay again applicable to automated production, makes the electric life of relay be able to promote greatly; In addition, this fixed contact is compared the root that saved fixed contact with traditional fixed contact with the structure that quiet contact chip is riveted mutually with the structure of quiet contact chip one, has saved the silver-colored slider material that waits noble metal, has reduced the production cost of relay.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, the quiet contact chip of a kind of combined type comprises quiet contact chip main body 1, on the quiet contact chip main body 1 in the corresponding relay position of moving contact 3 be wholely set convexity 2 towards moving contact 3 directions, be compounded with composite bed 21 on protruding 2.
In the foregoing description, the material of composite bed 21 can be silver, silver alloy, gold, billon, palladium, palldium alloy, platinum or platinum alloy or the like.
Claims (2)
1. the quiet contact chip of combined type comprises quiet contact chip main body, it is characterized in that on the described quiet contact chip main body that the position of moving contact is wholely set the convexity towards the moving contact direction in the corresponding relay, is compounded with composite bed on the described convexity.
2. the quiet contact chip of a kind of combined type as claimed in claim 1 is characterized in that the material of described composite bed is silver, silver alloy, gold, billon, palladium, palldium alloy, platinum or platinum alloy.
