Abstract
The utility model provides a novel bridge-shaped contact of a circuit breaker and mainly solves a problem that contact sheets are different to install and position and are not solid in positioning after being installed since the number of the contact sheets of a prior bridge-shaped contact is large. The novel bridge-shaped contact of the circuit breaker is characterized in that a first contact group and a second contact group are arranged on a support in mirror symmetry. The contact groups are composed of the contact sheets. Side faces of the contact sheets are provided with semi-circular limiting grooves. Limiting pins are arranged in the limiting grooves. An elastic piece is arranged in the support. Two ends of the elastic piece are connected with the limiting pins on the first contact group and the second contact group respectively. The contact sheets and the support are provided with positioning holes. Positioning shafts are arranged in the positioning holes. The positioning shaft is welded on the support. According to the utility model, since the novel bridge-shaped contact of the circuit breaker is provided with the positioning holes and the limiting grooves, the contact sheets can be fixed stably and solidly in the meantime of simplifying installation, so that the stability of a mechanism is improved.
Description
Technical field
The utility model relates to a kind of bridge-shaped contact, is specifically related to a kind of novel breaker bridge-shaped 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.
Bridge-shaped contact is the vitals of universal circuit breaker, and bridge-shaped contact is connected on the contact frame, and the contact frame is installed in the contact base.The contact side of bridge-shaped contact is burnishing surface, and each contact blade is fitted mutually, because contact blade is more, existing bridge-shaped contact exists contact blade to be difficult to the location is installed, and finishes the unstable problem in location, back of installing.
The utility model content
In order to overcome disadvantages of background technology, the utility model provides a kind of novel breaker bridge-shaped contact, has mainly solved bridge-shaped contact because contact is more, causes contact to be difficult to install the location and finish the back contact is installed is located unstable problem.
The technical scheme that the utility model adopts is: a kind of novel breaker bridge-shaped contact, comprise support, be arranged with first sets of contacts and second sets of contacts on the described support, described sets of contacts is made up of some contacts, described contact side is provided with the semicircle stopper slot, be provided with spacer pin in the described stopper slot, be provided with elastic component in the described support, described elastic component two ends are connected with spacer pin on second sets of contacts with first sets of contacts respectively, described contact and support are provided with location hole, be provided with locating shaft in the described location hole, described locating shaft and support welding.
Described elastic component is the torsion spring that two ends are provided with hook-shaped pivoted arm.
Described support bottom is provided with standing groove, and described standing groove and sets of contacts are suitable.
The beneficial effects of the utility model are: be provided with location hole, stopper slot, simplified install in, can stablize and firmly fix contact, improved mechanism stable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-support among the figure, 11-standing groove, 2-first sets of contacts, 3-second sets of contacts, 4-contact, 41-stopper slot, 5-spacer pin, 6-elastic component, 7-location hole, 8-locating shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As shown in Figure 1, a kind of novel breaker bridge-shaped contact, comprise support 1, be arranged with first sets of contacts 2 and second sets of contacts 3 on the described support 1, described sets of contacts is made up of some contacts 4, described contact 4 sides are provided with semicircle stopper slot 41, be provided with spacer pin 5 in the described stopper slot 41, be provided with elastic component 6 in the described support 1, described elastic component 6 two ends are connected with spacer pin 5 on second sets of contacts 3 with first sets of contacts 2 respectively, described contact 4 and support are provided with location hole 7, are provided with locating shaft 8 in the described location hole 7, described locating shaft 8 and support 1 welding.
Described elastic component 6 is provided with the torsion spring of hook-shaped pivoted arm for two ends, and hook-shaped pivoted arm snaps on the spacer pin 5, makes spacer pin 5 extruding contacts 4.
Described support 1 bottom is provided with standing groove 11, and described standing groove 11 is suitable with sets of contacts.Further fixed touch plate 4 prevents from that it from moving to get loose.
The concrete use of the utility model is as follows: the torsion spring two ends of deformation are connected with spacer pin 5, spacer pin 5 pushes first sets of contacts 2 and second sets of contacts 3 in stopper slot 41, first sets of contacts 2 and second sets of contacts 3 are pressed in support 1 standing groove 11 and at contact 4 are provided with locating shaft 8, locating shaft 8 and support 1 welding, contact 4 is securely fixed on the support.
The beneficial effect of utility model is: be provided with location hole, stopper slot, simplified install in, can stablize and firmly fix contact, contact can not come off in displacement, has improved mechanism stable.
