Description
Technical field
The present invention relates to a kind of drawer-type air circuit breaker, in particular it relates to a kind of for carrying electric current and there is the electric link system of undersized drawer-type air circuit breaker.
Background technology
Low-voltage circuit breaker is usually used in low-voltage distribution system, be used for connect, disjunction load, the safety of protection circuit and equipment, it belongs to low-voltage electrical apparatus category.
Fig. 1 show drawer-type air circuit breaker of the prior art for holding current-carrying electric link system, it is made up of current-carrying part (static contact), plug, chuck, chuck support and current-carrying part (client's terminals). Electric current flows through " plug ", " chuck " from " current-carrying part (static contact) ", " chuck support " flow to " current-carrying part (client's terminals) " or reverse flow. This system current paths length, current-carrying part are many. Therefore, adopt the volume of the drawer-type air circuit breaker of this system big and cost is high.
Therefore, this area also exists the length reducing current path and reduces the quantity of current-carrying part thus obtaining the demand of the electric link system of small volume and the low drawer-type air circuit breaker of cost.
Summary of the invention
In order to solve defect of the prior art, the present invention provides a kind of electric link system for holding current-carrying drawer-type air circuit breaker.
According to an aspect of the present invention, a kind of electric link system for holding current-carrying drawer-type air circuit breaker is provided, described electric link system includes the first current-carrying part, the second current-carrying part, spring contact and contact supporting, described spring contact is maintained at the outside of described first current-carrying part and the second current-carrying part by described contact supporting, when electric current is by described spring contact, described first current-carrying part and the second current-carrying part are applied pressure by described spring contact.
Described first current-carrying part and the second current-carrying part are respectively arranged with correspondence and oppositely facing the first current-carrying part Inside concave fillet and the second current-carrying part Inside concave fillet, being provided with the arc-shaped depression portion corresponding with each Inside concave fillet described on described contact supporting, described spring contact is maintained at described first current-carrying part Inside concave fillet, between the second current-carrying part Inside concave fillet and described arc-shaped depression portion.
Described first current-carrying part and the second current-carrying part are made by the cathode copper that electric conductivity is good and are plated the silver of suitable thickness.
Described spring contact well and is simultaneously had the copper alloy of good mechanical performance and makes and plate the silver of suitable thickness by electric conductivity.
Described contact supporting is working of plastics or other other material pieces that may be used for keeping described spring contact being suitable for.
Described spring contact is ringwise spiral coil.
The part that described first current-carrying part and the second current-carrying part contact with spring contact is cylindrical, and described contact supporting is annular.
Based on said structure, principles of the invention described further below.
This electric link system includes the first current-carrying part (underlying features corresponding to the static contact shown in Fig. 1) with Inside concave fillet, for the spring contact of current-carrying, the contact supporting that can be substantially secured to by described spring contact on the second current-carrying part and the second current-carrying part (the top features corresponding to the client's terminals shown in Fig. 1) with Inside concave fillet. Described first and second current-carrying parts are made by the cathode copper that electric conductivity is good and are plated on the silver of suitable thickness. Described spring contact well and is simultaneously had the copper alloy of good mechanical performance and makes and be plated on the silver of suitable thickness by electric conductivity. Described contact supporting can be working of plastics, does not fall off on the second current-carrying part for supporting that spring contact is placed in. When the first current-carrying part move downward reach appropriate location time, electric current can flow to the second current-carrying part or reverse flow by spring contact through carrying the first current-carrying part.
Because the first and second current-carrying parts are applied with spring force by described spring contact, so that when electric current flows through, the contact resistance between the first current-carrying part and spring contact, between spring contact and the second current-carrying part is little. As it is shown on figure 3, the electric current flow through on each semi-ring of described spring contact is equidirectional, therefore it is subject in figure electronic suction F, F toward each other shown in the direction of arrow ' each other. When electric current is very big, electronic suction will be greatly increased, and is compressed tightly against by described spring contact on described first and second current-carrying parts, it is ensured that the reliability of its current-carrying.
Can be seen that the electric link system for holding current-carrying drawer-type air circuit breaker according to the present invention includes three current-carrying component from the description above, namely the first current-carrying part, the second current-carrying part and spring contact. It is readily apparent that have employed, the volume of the drawer-type air circuit breaker of this system is little and cost is low, and by the minimizing of component count, the length of current path is reduced.
So far, in order to the present invention can be better understood in this detailed description, and in order to present contribution to the art can be realized better, the disclosure has outlined embodiments of the invention quite widely.
