The technical scheme of the utility model 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.
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.
