Abstract
The utility model relates to a multivariate contact head used for low-voltage electric appliance elements. The utility model is characterized in that both convex ends of a contacting bridge are respectively welded with silver base alloy contact points and copper-base alloy contact points for forming a ternary contact head structure, front end of the bulges of the contacting bridge is welded with silver base alloy contact points or copper-base alloy contact points for forming a binary contact head structure, and one end of the contacting bridge without bulge is welded with silver base alloy contact points and copper-base alloy contact points forming the other binary contact head structure. The utility model has the advantages that the utility model not only can ensure the important properties of electric appliances and the requirements of electrical wearing and temperature rising, but also can ensure the electric arc burning loss of the electric appliances under the condition of disconnecting or switching on larger failure current, and in addition, the utility model can save 50-70% of silver consumption.
Description
The utility model relates to a kind of multi-element contacts that is used for low voltage component.
In the known low voltage component, every electric equipment products that breakpoint is arranged adopt silver contact or silver-base alloy contact, though this structure has high conductivity and high-intensity characteristics, also have the big and high deficiency of cost of silver consuming amount.
The purpose of this utility model be to overcome the deficiency in the known technology and provide a kind of save silver consuming amount 50～70% have high conductivity and a high-intensity multi-element contacts that is used for low voltage component.
The purpose of this utility model is achieved in that
The structure of ternary contact of the present utility model is to be welded with silver-base alloy contact integral with it at an end of selecting for use touching of copper product to be shaped on projection on the bridge, touches the other end welding acid bronze alloy contact integral with it of projection on the bridge.
The structure of binary contact of the present utility model is to be welded with silver-base alloy contact integral with it at the front end of selecting for use touching of copper product to be shaped on projection on the bridge, can also be welded with acid bronze alloy contact integral with it.
The structure of binary contact of the present utility model is to be welded with silver-base alloy contact integral with it and acid bronze alloy contact at bridge one end that touches that is not shaped on projection of selecting copper product for use.
Advantage and the good effect that the utlity model has are: owing to adopt the contact of multi-factor structure in low voltage component, so not only guaranteeing the contact contact portion employing low resistance that the normal load electric current passes through, the silver-base alloy of high conductivity, and partly adopt copper product or acid bronze alloy producing electric arc, so both guaranteed the important performance of electric equipment products and the requirement of temperature rise and electrical wear, guaranteed also that electric equipment products disconnected the electrical arc erosion of connecting than the major break down electric current.In addition, the utility model is saved silver consuming amount 50～70%.
The utility model has following accompanying drawing:
Fig. 1 is a ternary structure of contact terminal front view of the present utility model;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is a binary structure of contact terminal front view of the present utility model;
Fig. 4 is the end view of Fig. 3;
Fig. 5 is the another kind of structure side view of Fig. 3.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
All electric equipment products contact systems that breakpoint is arranged, each contact point all has the certain end pressure and the excess of stroke, this structures shape closure between the dynamic and static contact and the moment of disconnection, should at first contact and dialysis by the front portion of contact, and after the complete closure of dynamic and static contact, actual contact partly is exactly the root of contact.Therefore for the contact of contact, have only the favorable linearity contact can guarantee the temperature rise index request of long-term energising, the utility model is exactly that the difference that around this principle reaches range of application has produced following three embodiment.
Embodiment one, sees also Fig. 1 and Fig. 2.
Be welded with silver-base alloy contact 3 integral with it in the projection upper end that is shaped on of touching on the bridge 1 of adopting copper product to make, the lower end is welded with acid bronze alloy contact 2 integral with it, and said structure forms the ternary fixed contact.Pei Dui ternary moving contact structure is to be welded with acid bronze alloy contact 2 integral with it on touching the bridge projection with it, and the lower end is welded with silver-base alloy contact 3 integral with it.
Embodiment two, see also Fig. 3 and Fig. 4.
With embodiment one difference is only to be welded with silver-base alloy contact integral with it at the front end that touches the bridge projection to form the binary fixed contact.Pei Dui binary moving contact structure is the silver-base alloy contact on the binary fixed contact to be changed to the acid bronze alloy contact get final product with it.This binary contact is applicable in the low voltage component of low breaking capacity.
Embodiment three, see also Fig. 3 and Fig. 5.
Be applicable to than another the binary structure of contact terminal in the low voltage component of high breaking capacity and be, be welded with silver-base alloy contact 3 integral with it at the same upper end that touches bridge 4 that adopts copper product but do not make projection, then the silver-base alloy contact is welded with it again and touches the acid bronze alloy contact 2 that bridge all is combined into one and forms the binary fixed contacts.Different is for Pei Dui binary moving contact structure and binary static contact structure with it, the position is switched in silver-base alloy contact and acid bronze alloy contact get final product.
