Abstract
The utility model discloses a contact system of a breaker. The contact system comprises a static contact silver contact block and a moving contact, one end of the moving contact is provided with a downward sliver contact block, the static contact silver contact block is fixedly connected with a conducting rod which penetrates through a plastic shell, the static contact silver contact block and the silver contact block of the moving contact are positioned at the same vertical line, the upper surface of the static contact silver contact block and the lower surface of the silver contact block of the moving contact are planes, and the upper surface of the static contact silver contact block and the lower surface of the silver block of the moving contact are parallel. According to the contact system of the breaker, the conductive distance of the contact system of the breaker can be shortened, the heating amount is reduced, and the consumables are saved.
Description
Technical field
The utility model relates to a kind of breaker contact system.
Background technology
Existing Small Form-Factor Pluggable circuit breaker, silver contact on the fixed contact that plug-in pin connects is connected with the body of rod of the conducting rod on socket by fixed contact, increased so whole current-carrying system conduction distance, and increased connection breakpoint, ampacity reduces, caloric value is larger, not only increased manufacturing procedure and difficulty of processing, and consumptive material is large.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of can shortening and in circuit breaker, conducts electricity distance, reduces caloric value, and saves the contact system of consumptive material.
For achieving the above object, the utility model adopts following technical scheme: a kind of breaker contact system, comprise fixed contact silver contact block and moving contact, described moving contact one end is provided with silver-colored contact block down, described fixed contact silver contact block is fixedly connected with the conducting rod through plastic casing, silver-colored contact block on described fixed contact silver contact block and moving contact is on same vertical line, above described fixed contact silver contact block and be plane below moving contact silver contact block, parallel with below the silver-colored contact block of moving contact above described fixed contact silver contact block.
As the further optimization of such scheme, described fixed contact silver contact block is identical and completely corresponding with moving contact silver contact block shape.
As the further optimization of such scheme, described fixed contact silver contact block and moving contact silver contact block are all circular or square.
The beneficial effects of the utility model main manifestations is: adopt contact system of the present utility model, conduction Distance Shortened, has reduced breakpoint, and whole heating resistor reduces; And a lot of processing technologys have been saved, cost.
Accompanying drawing explanation
Fig. 1 is existing contact system structure schematic diagram.
Fig. 2 is contact system structure schematic diagram of the present utility model.
Wherein 1 is Switch main body, the 2nd, and moving contact, the 3rd, socket, the 4th, conducting rod, the 5th, silver-colored contact block, the 6th, fixed contact, the 7th, trip bolt.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is further described specifically.
As shown in Figure 2, a kind of breaker contact system, comprise fixed contact silver contact block 5 and moving contact 2, described moving contact 2 one end are provided with silver-colored contact block 5 down, described fixed contact 6 silver medal contact blocks 5 are fixedly connected with the conducting rod 4 through plastic casing, silver-colored contact block 5 on described fixed contact 6 silver medal contact blocks 5 and moving contact 2 is on same vertical line, described fixed contact 6 silver medal contact blocks 5 above and be plane below moving contact 2 silver medal contact blocks 5, described fixed contact 6 silver medal contact blocks 5 are parallel below with moving contact 2 silver medal contact blocks 5 above, described fixed contact 6 silver medal contact blocks 5 are identical with moving contact 2 silver medal contact block 5 shapes and completely corresponding, described fixed contact 6 silver medal contact blocks 5 and moving contact 2 silver medal contact blocks 5 are all circular.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned execution mode, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
Do not depart from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific execution mode, scope of the present utility model is defined by the following claims.
