Embodiment
Expression is used for test pushbutton module 2, connector 3 and binding post 4 a kind of according to form of implementation of the present invention of a protection switch in Fig. 1 and 2.This test pushbutton module 2 is used in particular in the failure current protection switch, but also can provide in the protection switch of other modes.Binding post 4 is used for conductor or analog are connected to the protection switch of finishing assembling.
In conventional manufacture method, resistance 26 is connected with binding post 4 by a flexible conductor, in this flexible conductor and binding post 4 and resistance 26 welding.In this case, mean that the welding process of the heat load of assembly is carried out in formerly the operation usually in the manufacturing of protection switch, wherein, resistance 26 is welded on the flexible conductor, then manual test pushbutton module 2 is assembled around resistance 26.
By being used to carry out the contact portion 29 of removable connection, the manufacturing test probe module then is assembled to it in protection switch separately, can greatly simplify the manufacturing process of protection switch thus.
Also can change test pushbutton module 2 thus.Shown in Fig. 1 to 5, removable connection preferably forms by the sliding contact of preferred elastomeric.This permission simply and is promptly put into protection switch 1 to test pushbutton module 2, and simply, promptly and especially can not take out test pushbutton module 2 from protection switch 1 with damaging.
If connector 3 applies a power to contact portion 9 under connection status, then when being designed to abut on the shell 21, contact portion 29 shows advantage, can be supported on the shell 21 under the connection status at this connector 3 and contact portion 29.
When contact portion 29 is arranged on the end face 22 of shell 21, produce a kind of simple especially structure of test pushbutton module of the present invention.In this case, second joint 28 of resistance 26 can stretch out from shell 21 substantially as the crow flies, if resistance 26 is provided with on the longitudinally of shell 21.
If contact portion 29 and operating element 24 all are arranged on the same side 23 of shell 21, then contact position can especially clearly seen and controlled when taking out the upper casing of protection switch under the state of packing into.
By connector 3, test pushbutton module 2 and binding post 4 can not have under the closed condition of protection switch 1 interruptedly that conduction is connected, should connect and the location independent of operating element 24 at this.
In Fig. 3, amplify the connector 3 of expression, wherein be provided with one first contact-making surface 31, be used for detachably being connected with resistance 26 according to Fig. 1.
For connector 3 is installed, provide a middle section 34, wherein first contact-making surface, 31 relative these middle section elastic constructions.Can guarantee that thus first contact-making surface 31 applies a power for contact portion 29 under connection status, guarantee good electric contact thus and stop between first contact-making surface 31 and contact portion 29, to form air gap.
First contact-making surface 31 can comprise the contact zone 32 of at least two distances that separate each other, in this this at least two contact zone 32 connections each other in an electrically conductive.By forming a plurality of contact zones 32, can guarantee to be connected with connector 3 for binding post 4 leaves contact portion 29 different distances, a kind of form of implementation that is thus connected part 3 can be used for the multiple different version of protection switch.
In addition, connector 3 can have one second contact-making surface 33, is used for detachably being connected with binding post 4.By being configured to second contact-making surface of removable connection, when making protection switch, can in process step afterwards, carry out the connection between binding post 4 and the connector 3, can simplify work flow thus.
If the 33 relative central area 34 elasticity manufacturings of second contact-making surface then can effectively be avoided forming air gap between connector 3 and binding post 4, improve the reliability that is electrically connected between test pushbutton module 2 and the binding post 4.
The form of implementation of the connector of representing in Fig. 33 can be designed to thin plate bending spare in simple mode.In this case, some spring regions that comprise flex point 35 can be set, can guarantee the elastic construction of 31,33 pairs of central areas 34 of contact-making surface thus in simple mode.
Express a upper casing 11 of protection switch 1 in Figure 4 and 5, it has a breach 12, can hold the central area 34 of connector 3 in it.Fig. 6 represents the lower casing 15 of protection switch 1, and it has the pod that is used for test pushbutton module 2.
If binding post 4 and test pushbutton module 2 are arranged in the lower casing 15, connector 3 is arranged in the breach 12 of upper casing 11, then when placing on the lower casing 15, particularly form the conduction contact between the resistance 26 to upper casing 11 at binding post 4 and test pushbutton module 2.
Fig. 7 represents the plane graph of protection switch, a screw of wherein visible operating element 24 and binding post 4.Express the line of cut of Fig. 8 among this external Fig. 7.
From Fig. 7 and 8 visible under the assembled state of protection switch the position of test pushbutton module 2, binding post 4 and connector.Another binding post 4 of protection switch also can be connected with test pushbutton module 2 in another form of implementation of protection switch of the present invention, and/or the binding post with the protection switch that illustrates different numbers is provided.
The elastic construction of the contact-making surface 31,33 of connector guarantees that connector 3 does not hinder upper casing 11 to be assembled on the lower casing 15.
