Brief description of the drawings
Fig. 1 is a kind of structural representation of electrical power distribution breaker described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of electrical power distribution breaker of the utility model, including breaker body 1, breaker mounting plate 2,
Plug-in unit 3 and installation slot 4 are installed, installation plug-in unit 3 is connected with breaker body 1, and installation slot 4 is arranged on breaker mounting plate 2
On, breaker body 1 is connected by installing plug-in unit 3 and installation slot 4 with breaker mounting plate 2；Installation plug-in unit 3 includes linker
Seat 8 and elastic conducting strip 9, connection pedestal 8 are connected with breaker body 1, two elastic conducting strips 9 be arranged in parallel and its afterbody and
Connection pedestal 8 is fixedly connected, and the lateral surface on the head of two elastic conducting strips 9 is provided with arc bump, the He of elastic conducting strip 9
Connection pedestal 8 electrically connects with the circuit in breaker body 1；The inner of slot 4 is installed to set and the head of elastic conducting strip 9
The arc groove 10 of arc bump adaptation, is provided with elastic fit device, elastic fit device and breaker in arc groove 10
Circuit electrical connection on installing plate 2, the width of installation slot 4 are more than the diameter of arc bump.
Elastic fit device includes arc-like sheet 11 and installation spring 12, and the radius of arc groove 10 is more than the half of arc bump
Footpath, multiple arcs piece 11 are fixed on the medial surface of arc groove 10 by installing spring 12, and the arc core of multiple arcs piece 11 is equal
Set with the arc core homonymy of arc groove 10；
Connected between installation plug-in unit 3 and breaker body 1 by elastic engaging device, elastic engaging device includes engaging bullet
Spring 6 and conductive plate 7, the rectangular channel being adapted to being connected pedestal 8 is set on breaker body 1, is provided with the lateral wall of rectangular channel
The opening passed through for elastic conducting strip 9, slot 5 is provided with remaining side wall of rectangular channel, conductive plate 7 passes through snap-springs 6
It is fixed in slot 5, and conductive plate 7 is resisted against on connection pedestal 8, the lower end of connection pedestal 8 is provided with inclination groove, conductive
Plate 7 electrically connects with the circuit in breaker body 1.
A kind of operation principle of electrical power distribution breaker of the utility model is as follows：
When mounted, connection pedestal 8 is directed at rectangular channel, because the lower end of connection pedestal 8 moves down to tilt groove at it
