Abstract
A novel breaker's moving contact is disclosed. According to a present mechanism, after long-term use, elements are abraded and spring fatigue happens such that a moving contact and a fixed contact cannot be closed when a breaker is connected. The utility model mainly solves the above problem. The novel breaker's moving contact is characterized in that a spindle is provided with a second pin shaft, the contact body is connected with the spindle through a second pin shaft; a placement chamber is arranged in the spindle; a spring is disposed in the placement chamber; and one end of the spring is fixed in the placement chamber and the other end is connected with the contact body. The novel breaker's moving contact provided by the utility model is used to optimize the mechanism. During the long-time use, closure of the moving contact and a fixed contact will not be influenced when the breaker is connected.
Description
Technical field
The utility model relates to a kind of contact mechanism, is specifically related to a kind of novel breaker moving contact.
Background technology
Circuit breaker is a kind of existing hand switch effect, can transship automatically again and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; do not start asynchronous motor continually; power circuit and motor etc. are carried out protection, can automatic shutdown circuit when serious overload or short circuit and fault such as under-voltage take place for their, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And behind the disjunction fault current, generally do not need to change parts, therefore obtained to use widely.
Contact system is the important component part of miniature circuit breaker.At present commonplace a kind of structure is that a bearing pin is installed on the moving contact, and moving contact rotates around bearing pin, can make moving contact with the fixed contact closure or separates.This contact owing to component abrasion, spring fatigue in the mechanism, will produce spacing between moving contact and fixed contact after long-term the use, when close circuit breaker, circuit can't be connected.
The utility model content
In order to overcome disadvantages of background technology, the utility model provides a kind of novel breaker moving contact, has mainly solved existing mechanism after long-term the use, component abrasion, spring fatigue, the problem that moving contact and fixed contact can't be closed when causing circuit breaker to be communicated with.
The technical scheme that the utility model adopts is: a kind of novel breaker moving contact, comprise contact body, rotating shaft, connecting rod, described rotating shaft end is provided with first bearing pin, described connecting rod is connected with rotating shaft by first bearing pin, and described rotating shaft is provided with second bearing pin, and described contact body is connected with rotating shaft by second bearing pin, be provided with placed cavity in the described rotating shaft, be provided with spring in the described placed cavity, described spring one end is fixed in the placed cavity, and an end is connected with contact body.Described contact body and rotating shaft are provided with some adaptive location holes mutually, and described location hole is that the center of circle distributes with second bearing pin.
The beneficial effects of the utility model are: contact body and connecting rod are separated, and be provided with spring between contact body and connecting rod, when having guaranteed that circuit breaker is communicated with, the moving contact body can contact with fixed contact, has improved the stability of circuit breaker.
Description of drawings
Fig. 1 is structural representation view of the present utility model.
1-contact body among the figure, 2-rotating shaft, 21-placed cavity, 3-connecting rod, 4-first bearing pin, 5-second bearing pin, 6-spring, 7-location hole.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As shown in Figure 1, a kind of novel breaker moving contact, comprise contact body 1, rotating shaft 2, connecting rod 3, described rotating shaft 2 ends are provided with first bearing pin 4, and described connecting rod 3 is connected with rotating shaft 2 by first bearing pin 4, described rotating shaft 2 is provided with second bearing pin 5, described contact body 1 is connected with rotating shaft 2 by second bearing pin 5, is provided with placed cavity 21 in the described rotating shaft 2, is provided with spring 6 in the described placed cavity 21, described spring 6 one ends are fixed in the placed cavity 21, and an end is connected with contact body 1.
Described contact body 1 is provided with some mutual adaptive location holes 7 with rotating shaft 2, and described location hole 7 is that the center of circle distributes with second bearing pin 5.
The concrete use of the utility model is as follows: during work, when contact body 1 contacted with another fixed contact body, because the effect of rotating shaft 2 pressure, spring 6 compressions had guaranteed that the contact of contact body connects; When circuit breaker uses for a long time, because component abrasion, spring fatigue in the mechanism, when causing producing spacing gradually between the contact body 1, spring can extend gradually, keeps the contact body contact.
The beneficial effect of utility model is: contact body and connecting rod are separated, and be provided with spring between contact body and connecting rod, when having guaranteed that circuit breaker is communicated with, the moving contact body can contact with the fixed contact body, has improved the stability of circuit breaker.
