Abstract

The utility model provides a contact bridge used for a single-acting rocker switch. The contact bridge comprises contact operational layers and a contact bridge conducting strip. The contact operational layers are located on end portions of the contact bridge conducting strip and form one body structure with the contact bridge conducting strip. Further, the contact bridge conducting strip and the contact operational layers are combined into a one-piece structure through a hot rolling processing mode. By using the contact bridge used for the single-acting rocker switch of the utility model, the one-piece structure is used to replace a riveting structure of a rivet contact and the contact bridge in the prior art. The contact and the contact bridge conducting strip do not have a poor contact problem. Simultaneously, the contact and the contact bridge conducting strip possess best combination intensity so that an electric current of the rocker switch can be greatly increased. A temperature rise is low. A service life is long and the contact bridge is safe and reliable. The processing is simple and cost is low.

Description

Single action rocker switch contact bridge

Technical field:

The present invention relates to a kind ofly for the switch fitting on small household appliance, specifically refer to single action rocker switch contact bridge.

Background technology:

The break-make extensive use rocker switch of small household appliance power supply, its contact bridge is core component, plays the key effect of insulating power supply, its performance quality is determining the effect of on/off.The contact bridge of existing rocker switch is to be formed by rivet contact and conducting strip riveted joint, easily heating of long-time energising, the easy oxidation of riveted joint place of rivet is loosening, cause not even conducting or there will be interrupted connection phenomenon of loose contact, cause damage to the electrical equipment main body, the serious overheated melting welding that also there will be, burn electrical equipment, leads to security incident.

Summary of the invention:

For overcoming the not enough and shortcoming of existing rocker switch contact bridge structure, the invention provides the contact bridge that a kind of contact and tactile bridge conducting strip are integrated, there is processing simply, the energising performance is good, not there will be superheating phenomenon, long service life, safe and reliable characteristics.

The utility model is achieved by the following technical solution, and the single action rocker switch is characterized in that comprising contact working lining and tactile bridge conducting strip with contact bridge, and the contact working lining is positioned at the end of touching the bridge conducting strip, and is structure as a whole in tactile bridge conducting strip.

Further touch bridge conducting strip and contact working lining and be integrated with the method strong bonded of hot rolling, then through cold finish rolling system processing, last punch forming and obtain two moving rocker switch contact bridges.

The beneficial effects of the utility model:

Single action rocker switch contact bridge described in the utility model, the riveted structure of rivet contact and tactile bridge in the prior art that adopted structure that contact and tactile bridge conducting strip are integral type to replace.Make contact and tactile bridge conducting strip not have the problem of loose contact, contact and tactile bridge conducting strip connect as one the formula structure by the mode of hot rolling simultaneously.There is best bond strength, can significantly improve the electrical current of rocker switch, and temperature rise is low, long service life, safe and reliable.There is the simple cost of processing low simultaneously.

The accompanying drawing explanation:

Fig. 1 is the cutaway view of single action rocker switch described in the utility model with contact bridge

Embodiment:

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail, the single action rocker switch contact bridge that the utility model provides as shown in Figure 1, comprise contact working lining 1 and tactile bridge conducting strip 2, contact working lining 1 is positioned at the end of touching bridge conducting strip 2, and is the integral type structure in tactile bridge conducting strip 2.The material of wherein touching bridge conducting strip 2 is red copper or brass, and the material of contact working lining 1 is silver or the silver alloy that conductance is high.

Preferred contact bridge is to touch bridge conducting strip 2 and contact working lining 1 to connect as one the formula structure in the mode of hot rolling, has best bond strength.Can on red copper or brass sheet material matrix end surfaces, establish location notch during concrete the manufacture; inlay silver bar or the silver alloy bar obtains base substrate in location notch; again base substrate is rolled into to one through Buchholz protection by bi-material; obtain the contact bridge material that contact that combined strength bination is high and tactile bridge conducting strip are integrated; then the diffusion annealing of contact bridge material is eliminated stress; obtain and require size through cold finish rolling system; punch forming again; can obtain single action rocker switch contact bridge described in the utility model, as Fig. 1.

The utility model is not limited to above-mentioned embodiment; persons skilled in the art are according to the disclosed content of the utility model; can adopt other multiple embodiment to implement the utility model, therefore every employing project organization of the present utility model and thinking are done some simple designs that change or change and are all fallen into the utility model protection range.

Claims

1. single action rocker switch contact bridge is characterized in that: comprise contact working lining and tactile bridge conducting strip, the contact working lining is positioned at the end of touching the bridge conducting strip, and contact working lining and tactile bridge conducting strip are structure as a whole.

2. single action rocker switch contact bridge according to claim 1 is characterized in that: touch bridge conducting strip and contact working lining with the mode of the hot rolling formula structure that is combined as a whole, through cold rolling, punch forming.
