Abstract
The utility model discloses a static contact point component of a rocker switch. The static contact point component comprises a contact point working layer and a conductive sheet. The conductive sheet is arranged on the top part of the contact point working layer, and an integrated structure is formed by the conductive sheet and the contact point working layer. With adoption of the structure, the static contact point component of the rocker switch has characteristics of being simple in processing, low in production cost, excellent in power-on performance and safe and reliable so that an overheating phenomenon can be avoided.
Description
Technical field
The present invention relates to a kind ofly for the switch fitting on small household appliance, specifically refer to the fixed contact structure that a kind of rocker switch is used.
Background technology
Small household appliance break-make power supply extensive use rocker switch, its fixed contact and contact bridge are the core components of electric current of make-and-break, play the key effect of isolation, its performance quality is determining the effect of break-make.The fixed contact of existing rocker switch is to be formed by rivet contact and conducting strip riveted joint, long-time energising easily riveted joint place of heating rivet is easily become flexible, cause loose contact to there will be interrupted connection phenomenon, give the serious overheated melting welding that also there will be that causes damage of electrical equipment main body, electrical equipment is burnt, lead to security incident.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, the fixed contact structure that the utility model provides a kind of contact working lining and conducting strip to be integrated, has processing simple, production cost is low, the features such as energising function admirable, there will not be superheating phenomenon, safe and reliable.
The fixed contact parts of the utility model rocker switch, comprise contact working lining and conducting strip, and conducting strip is positioned at the top of contact working lining, and are structure as a whole with contact working lining.
Adopt the fixed contact parts of the rocker switch of said structure, the structure becaming one with conducting strip and contact working lining has replaced rivet structure of the prior art, avoided between contact working lining and conducting strip may problem, the problem includes: problems such as loose contacts, increased the bond strength between contact working lining and conducting strip simultaneously, improved the electrical current of rocker switch, and temperature rise is low, long service life, processing is simple, and production cost is lower.
As further improvement of the utility model, described contact working lining and conducting strip junction raise up and form arch bridge-like structure.Save raw material and reduced again production cost simultaneously.
As further improvement of the utility model, the thickness of the junction of described conducting strip and contact working lining is no more than 1 millimeter, adopts the fixed contact parts of the rocker switch of this structure, can improve the electrical current of switch block.
Compared with prior art, the beneficial effect of the utility model fixed contact parts is:
(1) improve the bond strength between contact working lining and conducting strip, improve electrical current, and temperature rise is low;
(2) avoid the situation of loose contact to occur, long service life, safe and reliable;
(3) production and processing cost is low.
Accompanying drawing explanation
Fig. 1 is the cutaway view of the utility model rocker switch fixed contact parts.
Embodiment
As shown in Figure 1, this specific embodiment is a kind of fixed contact parts of rocker switch, comprise contact working lining 2 and conducting strip 1, wherein the material of conducting strip 1 is red copper or brass, the material of contact working lining 2 is silver or the silver alloy that conductance is high, conducting strip 1 is positioned at the top of contact working lining 2, and is structure as a whole with contact working lining 2.Preferred fixed contact parts are that conducting strip 1 and contact working lining 2 connect as one formula structure in the mode of hot rolling, when concrete manufacture, on conducting strip 1 matrix end surfaces, establish location notch, the making material of inlaying contact working lining 2 in location notch obtains base substrate, again base substrate is rolled into one through Buchholz protection by bi-material, obtain the fixed contact parts that contact working lining 2 that combined strength bination is high and conducting strip 1 are integrated, then this fixed contact parts diffusion annealing is eliminated stress, require punch forming of size through being cold-rolled to, can obtain the fixed contact parts of rocker switch described in the utility model.
Contact working lining 2 raises up and forms arch bridge-like structure with conducting strip 1 junction.The upper surface of this arch bridge-like structure can be curved surface with the contact-making surface of moving contact, can be also plane, and can closely cooperate as preferably with moving contact, the fixed contact shown in Fig. 1 is the plane contact-making surface of designed fixed contact as a reference.
In order to improve the energising efficiency of switch block, the thickness of the junction of conducting strip and contact working lining is no more than 1 millimeter.
Claims (3)
1. fixed contact parts for rocker switch, comprise contact working lining and conducting strip, it is characterized in that: described conducting strip is positioned at the top of contact working lining, and are structure as a whole with contact working lining.
2. the fixed contact parts of rocker switch according to claim 1, is characterized in that: described contact working lining and conducting strip junction raise up and form arch bridge-like structure.
