Abstract
An electromechanical relay, in particular, a moveable contact arm for a relay. The contact arm is manufactured by brazing contact pieces from both sides to a metal blade. In order to avoid excess brazing material contaminating the contact surfaces, the metal blade is provided with a through-hole over which the contact pieces are centered from both sides. The through-hole serves as a braze reservoir. Thus, excess brazing material flows into the hole which in turn limits braze flow up the contact edges which would result in contamination of the contact surfaces.
Description
The present invention relates to a kind of electromechanical switching device, as relay, relate in particular to a kind of electromechanical switching device of charged contact arm, contact arm all has contact chip as the both sides of moving contact arm.
Be used for the electromechanical switching device of high current at relay and other, make when electrically contacting arm, generally all use riveted joint type contact.For example, all need in both sides the indirect contact arm of contact contact piece structure (as SPDT, Break-Maker, Form C), prefabricated riveted joint contact, pile under the hole on the arm then, and make the contact distortion, form the contact-making surface that connects with both sides at contact arm.The known method of this making contact arm make processing contact rivet cost very high.In addition, the final contact arm structure that forms can't satisfy the requirement in harsh useful life in some switch application occasion.
British patent specification GB-A-1158119 has described a kind of elasticity brake lining assembly (springblade assembly) and preparation method thereof, and it has the elasticity brake lining of a plurality of stacks, through the connection of elasticity brake lining contact both sides sheet and be clamped together.Specifically, the elasticity brake lining has the through hole of mutual aligning, and a contact head covers the hole of a plurality of elasticity brake lining one sides, and a supporter covers the hole of opposite side.Contact head and supporter connect together through welding.Because a plurality of elasticity brake linings overlap together, contact chip must have good electrical conductivity when connecting in the hole of aiming at.This just requires each contact chip to have a connector, puts in each respective aperture from contact head and/or supporter to be connected with other contact chip.So contact chip becomes rivet shape, and similar to above-mentioned rivet contact, the cost of manufacture height.
Another kind of known method is, downcuts contact chip from a contact band, utilizes melts combine method such as resistance brazing that contact chip is connected on the described surface that electrically contacts arm.And need not on the contact arm surface, to form through hole.One side of this contact chip generally has the bed course of copper alloy, is used for contact chip is soldered to the plane of contact arm or disconnecting link reed.The contact arm made from the sheet of the contact band of soldering generally can satisfy the requirement in the useful life of harshness.
But in connection or brazing process, excessive fusion brazing material can cover the side of contact chip, and in some cases, flows on the surface of contact chip.Partly cause is that employed electrode applies power on contact chip in brazing process, make its location, and maintenance and contact arm can accept electrically contact.This situation can cause contact arm operation in produce Contact welding, and reduced the life-span of electrode in the electric resistance welding.Very disadvantageously, because the restriction of contact band manufacture craft, the amount of copper alloy coating or thickness can not reduce fully, and promptly this Albatra metal-can only reach a certain minimum thickness on tape.
Therefore, an object of the present invention is to overcome the shortcoming of prior art.
Specifically, the purpose of this invention is to provide a kind of dynamo-electric machine switch, it electrically contacts the contact chip that arm uses the cheapness with simple shape and plane, and these contact chips can be soldered to the both sides of metal brake lining, and can not produce the problem that excessive brazing material influences contact surface.
