Embodiment
Be clearly and completely described the technical solution of the utility model below in conjunction with accompanying drawing, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 to Fig. 2 shows a kind of circuit breaker embodiment that the utility model provides.The binding post that this circuit breaker comprises housing 1, operating mechanism, contact system, various release (generally including overcurrent trip, shunt release, thermal overload release and under-voltage release), arc quenching system and is connected with outer lead.In order to make normal operation of circuit breaker, realizing the design function of circuit breaker, needing between each parts in circuit breaker to be connected by design by wire, such as, between release and contact system, between binding post and contact system, etc.The parts connected are needed all to be called " needing connector 2 " herein.
In the utility model, described need is connected by syndeton 3 between connector 2.Described syndeton 3 comprises substrate 31, wire and plug connector.Described wire is fixed on described substrate 31, and described plug connector is connected with wire.Described syndeton 3 coordinates by respective plug connector between connector 2 connection realized between the two with described need.Particularly, described plug connector is the general designation of plug-in unit and fitting.What cooperatively interact describedly needs in connector 2 and described syndeton 3, and a side installs plug-in unit, and the opposing party is provided with fitting.The plug-in unit cooperatively interacted and fitting make according to unified standard, and both cooperatively interact and can realize conducting, thus realize describedly needing being communicated with of connector 2 and described syndeton 3.Plug connector arranges number and setting position can be determined according to actual conditions, thus adapts to the connection needing connector 2 of diverse location.
As described syndeton 3 one kinds preferred embodiment, described syndeton 3 comprises printed circuit board (PCB) (Printedcircuitboard, PCB), and namely circuit design makes printed circuit board (PCB) after completing.At present, printed circuit board (PCB) possesses skills maturation and low cost and other advantages, and adopts printed circuit board (PCB) by the upper mistake reducing wiring and assembling largely, improves the gentle productive labor rate of Automated water.Described plug connector is fixedly installed on this printed circuit board (PCB).
Installing hole on described substrate 31, described housing 1 is provided with the mount pad arranging and coordinate with described installing hole.Described syndeton 3 is fixedly installed in described housing 1 by the screw element being arranged in this installing hole with coordinating of described mount pad.Herein; housing 1 only should not be confined to the shell mechanism of circuit breaker; should be appreciated that and become the shell structure that other parts of circuit breaker provide protective effect, and, to fix with shell structure and for fixing or locate the general designation of structure of other parts of circuit breaker.
Described substrate 31 is provided with feature holes, described housing 1 is provided with the feature coordinated with feature holes protruding.Realize the assembling of described syndeton 3 uniqueness by the cooperation between described feature holes and described feature projection, namely the cooperation of feature holes and feature projection has uniqueness, thus is beneficial to the accuracy and efficiency of assembling that improve circuit breaker assembling.It should be noted that, feature holes is not limited to independent hole, can be the general designation in a series of hole.In the present embodiment, the permutation and combination of the geometrical properties such as the size of feature holes passing hole, the number in hole, the spacing in hole and the spread geometry in hole identifies the uniqueness of described syndeton 3.
The technical program, installing hole and mount pad can be selected respectively as feature holes and feature projection, and so design can make the feature of syndeton 3 more simple, and processing and fabricating is more convenient.
As the another kind of execution mode of described syndeton 3, described substrate 31 is platy structure, this substrate 31 offers the draw-in groove of engaging wire, and this draw-in groove is for the position in the path and fixing cord that limit wire.On described substrate 31, the position of draw-in groove and path need be designed by circuit requirement.And comparatively simple circuit is connected, realize by common substrate.Described common substrate is provided with that multiple tool is at regular intervals, the horizontal draw-in groove that be arranged in parallel and longitudinal draw-in groove, then arranges wire according to the actual requirements and connects.As another kind of execution mode, substrate 31 is platy structure, and it is offered the through hole of restriction wire, its functions and principles is identical with the syndeton 3 with draw-in groove.
As preferred embodiment, described plug-in unit is row's pin 32, and described fitting is row female 21.
Described syndeton 3 can be connected with another syndeton, is connected by plug connector equally between the two.
The shape and size of described syndeton 3 are determined according to actual conditions.Preferably, two adjacent need are only provided with a syndeton 3 between connector 2.Design like this can make the work of wire to moving component not produce interference, and profit improves efficiency of assembling.
