Abstract
The utility model relates to a relay for eliminating the riveting resistance between relay contacts and electrodes, comprising a relay body, wherein the relay body is provided with a fixed plate, a moving plate and a composite woven soft copper belt, both ends of the fixed plate are welded with a silver fixed contact and a tungsten steel moving contact respectively, between the fixed plate and the composite woven soft copper belt there is provided a stainless steel elastic plate, the positions of the stainless steel elastic plate, corresponding to the silver fixed contact and the tungsten steel fixed contact are riveted with a silver moving contact and a tungsten steel moving contact, the composite woven soft copper belt is formed by a multistrand woven soft copper belt in a manner of welding, the composite woven soft copper belt is provided with three terminals, one of the three terminal is welded with the moving plate, and the other two terminals are welded with the riveting surfaces of the silver moving contact and the tungsten steel moving contact. The relay for eliminating the riveting resistance between relay contacts and electrodes has the beneficial effects of directly welding the two electrodes, i.e., the fixed plate and the moving plate, with the contacts in a spot welding mode, thereby eliminating the contact resistance caused by riveting.
Description
Technical field
The utility model relates to a kind of relay of eliminating relay contact and electrode rivet connection resistance.
Background technology
The contact of common relay all is riveted on the electrode on the market, just has like this a resistance between contact and the electrode, and the size of this resistance is relevant with surface treatment and the riveting process of contact and electrode.But this resistance exists all the time, and can be along with the lengthening of service time, the intensification of surface oxidation degree, and resistance can be increasing.This resistance is on low power relay, because the electric current little effect is little.But more than the middle power particularly on the high power relay, because large this resistance of electric current can cause local pyrexia between contact and electrode, gently then make electrode deformation, heavy then electrode is blown, the contact comes off, relay damaged.
The utility model content
The purpose of this utility model provides a kind of relay of eliminating relay contact and electrode rivet connection resistance, to avoid riveting the contact resistance that causes, blows thereby produce electrode, and the contact comes off, and makes relay damaged.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of relay of eliminating relay contact and electrode rivet connection resistance, comprise the relay main body, described relay main body is provided with still, moving plate and combined type braiding soft copper band, there are silver-colored fixed contact and wolfram steel fixed contact in described still two ends respectively melting welding, be provided with the stainless steel shell fragment between still and the combined type braiding soft copper band, on the stainless steel shell fragment with silver-colored fixed contact and wolfram steel fixed contact corresponding position pressed respectively silver-colored moving contact and wolfram steel moving contact; Described combined type braiding soft copper band is formed by the melting welding of multiply braiding soft copper band, and this combined type braiding soft copper band is provided with three terminations, and wherein a termination and moving plate weld, two other termination respectively with being welded by the riveting face of silver-colored moving contact and wolfram steel contact.
The beneficial effects of the utility model are: with two electrodes, namely still and moving plate all adopt direct spot welding with being connected of contact, the contact resistance of having avoided riveted joint to cause.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the described a kind of structural representation of eliminating the relay of relay contact and electrode rivet connection resistance of the utility model embodiment.
Embodiment
As shown in Figure 1, the described a kind of relay of eliminating relay contact and electrode rivet connection resistance of the utility model embodiment, comprise relay main body 1, described relay main body 1 is provided with still 2, moving plate 5 and combined type braiding soft copper band 6, there are silver-colored fixed contact 3 and wolfram steel fixed contact 4 in described still 2 two ends respectively melting welding, be provided with stainless steel shell fragment 7 between still 2 and the combined type braiding soft copper band 6, on the stainless steel shell fragment 7 with silver-colored fixed contact 3 and wolfram steel fixed contact 4 corresponding positions pressed respectively silver-colored moving contact 8 and wolfram steel moving contact 9; Described combined type braiding soft copper band 6 is formed by the melting welding of multiply braiding soft copper band, this combined type braiding soft copper band 6 is provided with three terminations, a wherein termination and moving plate 5 welding, two other termination respectively with being welded by the riveting face of silver-colored moving contact 8 and wolfram steel contact 9, thoroughly eliminated the contact resistance that contact and two electrodes (still 2 and moving plate 5) produce because of riveted joint face, the electrode of having avoided so having produced blows with the contact and comes off, and makes relay damaged.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection range of the present utility model.
Claims (1)
1. relay of eliminating relay contact and electrode rivet connection resistance, comprise the relay main body, described relay main body is provided with still, moving plate and combined type braiding soft copper band, it is characterized in that, there are silver-colored fixed contact and wolfram steel fixed contact in described still two ends respectively melting welding, be provided with the stainless steel shell fragment between still and the combined type braiding soft copper band, on the stainless steel shell fragment with silver-colored fixed contact and wolfram steel fixed contact corresponding position pressed respectively silver-colored moving contact and wolfram steel moving contact; Described combined type braiding soft copper band is formed by the melting welding of multiply braiding soft copper band, and this combined type braiding soft copper band is provided with three terminations, and wherein a termination and moving plate weld, two other termination respectively with being welded by the riveting face of silver-colored moving contact and wolfram steel contact.
