Technical field
The present invention relates to the electric power system low-voltage electrical apparatus, especially relate to a kind of low-voltage electrical apparatus contact system structure.
Background technology
The contact system structure is the key structure of low-pressure electronic equipment product, and the change of contact system frame mode will directly influence the height of manufacturing cost, also has influence on the complexity of contact system technology.Whether the one side low-voltage electrical apparatus contact parameter excess of stroke and end pressure depend primarily on the contact system structural design reasonable; On the other hand, low capacity depends on also to the manufacturability and the properties of product of products with larger capacity structural design whether the contact system structural design is reasonable.
Tradition contact system structure adopts global design, and this just makes the contact system structure extremely diversified from the small-capacity product to the products with larger capacity, and dilatation is very inconvenient, thereby causes the manufacturing process complicacy and the cost height of contact system structure.
Summary of the invention
Technical problem to be solved by this invention is to the problem that exists in the prior art a kind of low-voltage electrical apparatus contact system structure to be provided; Its objective is through changing moving contact sheet number and the spring force that mode arranged side by side is provided with the capacity of low-voltage electrical apparatus system configuration is regulated; On the basis of improving performance of products, reduce the manufacturing cost of system.
Technical scheme of the present invention is this kind low-voltage electrical apparatus contact system structure; Comprise last connecting rod and lower link through first connection; Lower link is connected with moving contact structure through second, and moving contact structure is connected with fixed contact, and moving contact structure is connected with gusset piece through soft connection.
Described moving contact structure comprises moving contact; The top of every moving contact is provided with spring; The supporter that spring is positioned is sleeved on the outside of every moving contact and spring; Moving contact is provided with and is used to install second hole with fixed axis, and supporter is provided with and corresponding hole, moving contact position.
Be provided with the axle sleeve that prevents moving contact and lower link friction between described moving contact and the lower link.
Moving contact in the described moving contact structure has two at least, and adjacent two moving contacts are placed side by side, and all moving contacts form every moving contact structure mutually through second with fixed axis.
Described first is passed through the first split washer axial restraint; Described second is passed through the second split washer axial restraint.
A kind of low-voltage electrical apparatus contact system structure with said structure has the following advantages:
1. every moving contact of this kind low-voltage electrical apparatus contact system structure can form separate structures; Every moving contact structure can be realized the excess of stroke and end pressure separately; Just can realize that from the low capacity increase-volume to big capacity, simple in structure, dilatation makes things convenient for as long as increase the sheet number of moving contact arranged side by side.
2. this kind low-voltage electrical apparatus contact system structure adopts Redundancy Design, and every moving contact just can satisfy the end pressure requirement as long as change touch spring power, can guarantee to have excellent contact between moving contact and the fixed contact of product.
3. this kind low-voltage electrical apparatus contact system structure has greatly reduced manufacturing cost and the process complexity of contact system in series of products.
