Abstract

The utility model relates to an electric outlet with strengthened elastic contact pieces. Each elastic contact piece (1) of the jacks of the utility model is composed of two layers of materials. The inner layer (2) is red copper used for participating in electric conduction, the outer layer (3) is stainless steel or spring steel mainly used for keeping the elasticity of the elastic contact pieces, and the inner layer and the outer layer are welded into one by means of composite techniques. The utility model has the advantage that the elastic contact pieces keep enough elasticity for a long period to enable a socket to contact a plug tightly, and has the advantages of small contacting resistance, lower energy consumption, reliable performance properties, long service life, etc.

Description

Electric outlet with strengthened elastic contact pieces

The utility model relates to a kind of supply socket that connects or cut off the electricity supply.

Elastic Contact conducting element---intermediate plate in the existing supply socket, system uses red copper to make usually, though red copper has good electric conductivity, its intensity is low, poor flexibility, easy deformation is because of arc discharge is annealed red copper afterwards more so.Because there is above-mentioned deficiency in the red copper performance, distortion can appear in the intermediate plate that socket is in use made by red copper and elasticity weakens, and causes the socket and plug loose contact, and contact resistance increases, and energy consumption increases, and influences its result of use.

In order to overcome the above-mentioned defective of existing socket, the utility model provides the supply socket of a kind of its elastic clip through adopting stainless steel or spring steel to strengthen.Fig. 1 is the schematic diagram of the novel socket of a kind of three jacks, Fig. 2 is the profile of the jack of Fig. 1, (1) is an elastic clip of being made up of two layers of material in the novel socket among Fig. 2, and the internal layer of (1) (2) is a red copper, and outer (3) are austenitic stainless steel or spring steel.The utility model, except that its elastic clip system was made up of two layers of material, remaining component and structure and existing supply socket were identical.

The utility model has following advantage and good effect:

The supply socket of its elastic clip through adopting stainless steel or spring steel to strengthen,

Red copper in its intermediate plate mainly plays the contact electric action, and is promptly the same with existing socket, the advantage of having utilized red copper to conduct electricity very well; And austenitic stainless steel in the intermediate plate or spring steel, then because of its intensity height, good springiness, be difficult for annealing softening, inherent characteristic such as not yielding, the main skeleton function that rises in intermediate plate, can make intermediate plate possess enough elasticity for a long time, can keep the tight contact of socket and plug chronically; Thereby make socket, plug through after repeatedly repeating insertion and extracting, still have the less and lower advantage of energy consumption of contact resistance, and improved their dependability and the useful life that has prolonged them.

The utility model is applicable to the supply socket with two jacks or three jacks or four jacks that can insert a plug, also is applicable to the power distributor seat that can insert a plurality of plugs simultaneously; Elastic clip in all jacks of novel socket all is through strengthening.

Accompanying drawing 1 is one of embodiment of the present utility model, is a kind of three receptacle electrical connectors that can only insert a plug, realizes that difficult point of the present utility model is to make the elastic clip through strengthening; Its best manufacture method is: make red copper by explosion cladding process or composite technique for rolling earlier---austenitic stainless steel or spring steel composite plate; Carry out blanking punched and brake forming then.It is identical with the production technology of existing like product with production technology such as assembling that other part of novel socket is made.

Claims

The supply socket of elastic clip through strengthening is characterized in that: the elastic clip (1) in all jacks of this supply socket constitutes by two layers of material, and the internal layer of (1) (2) is a red copper, and outer (3) are austenitic stainless steel or spring steel.
