Below, with reference to accompanying drawing, embodiments of the present invention are described in detail.
[the first execution mode]
Fig. 1 is the stereogram of the moving contact member 1 that first embodiment of the invention is described.Fig. 2 is the figure of the moving contact member 1 that first embodiment of the invention is described, Fig. 2 (a) is vertical view, and Fig. 2 (b) is end view.Fig. 3 is the figure of the moving contact member 1 that first embodiment of the invention is described, Fig. 3 (a) is the sectional view of the III-III line shown in Fig. 2 (a), and Fig. 3 (b) is the amplification sectional view of the P part shown in Fig. 3 (a).
As shown in Figure 1, moving contact member 1 is configured to, and possesses: bellying 11, is formed by the metallic plate of conductivity, can carry out rotary movement by pressing; And skirt section 12, formed continuously from edge, the periphery 11a of bellying 11.Thus, skirt section 12 is formed continuously with edge, the periphery 11a of bellying 11, therefore becomes the formation supported bellying 11.
As shown in Figure 2, bellying 11 bloats as dome-shaped, at the specified diameter of dome towards top side (the Z1 direction shown in Fig. 1)
circle region in specify that curvature bending is formed, and at specified diameter
circle and the maximum gauge of dome
circle between region in, also to specify that curvature bending is formed.
In addition, the skirt section 12 formed continuously with edge, the periphery 11a of bellying 11, is formed obliquely with predetermined angular.In this case, as shown in Fig. 2 and Fig. 3 (b), skirt section 12, in the roughly consistent mode of the tangential direction SD of the tangent line extended along dome radius direction DD of edge, the periphery 11a with bellying 11, is formed continuously from edge, the periphery 11a of bellying 11.That is, skirt section 12 is connected lenitively with bellying 11, the boundary line between skirt section 12 and bellying 11 does not exist sweep, and fulcrum when overturning is not formed in this part.
In addition, as shown in Figure 1 to Figure 3, skirt section 12 has the notch 32 of incision at the position clipping bellying 11 and opposed surrounding, and the position beyond the notch 32 in skirt section 12 is formed as contact site 52.In addition, the notch 32 in skirt section 12 is formed as bloating to bellying 11 side (with reference to Fig. 2 (b)), so that become can ground connection position the position beyond the notch 32 in skirt section 12.In addition, the coupling part 42 between the notch 32 in skirt section 12 and contact site 52 connects deviously.In addition, the maximum outer shape MS overlooked of the contact site 52 in skirt section 12, is formed as diameter
round shape.In addition, the shape of the contact site 52 in skirt section 12 is formed as arc-shaped, but also can be formed as linearity.
As shown in Fig. 2 (a), the cut sides shape PS overlooked of notch 32 becomes rectilinear form.Especially, the cut sides shape PS being formed at surrounding is, opposed cut sides shape PS is configured in parallel position each other and adjacent cut sides shape PS is configured in orthogonal position each other, and the otch outer shape OS therefore cut sides shape PS prolongation be connected to becomes square (roughly square).In addition, the interval D S between pair of notches portion 32 is than the maximum gauge of the dome of bellying 11
greatly.The cut sides shape PS of first embodiment of the invention is almost made up of rectilinear form, but also can be the curve shape comparatively relaxed.
The moving contact member of the present invention 1 of formation like this, to retain the mode of bellying 11 completely, on skirt section 12, only form the notch 32 of surrounding, skirt section 12 is formed continuously from edge, the periphery 11a of bellying 11, compared with the situation that therefore notch is set with the part at bellying and the situation (conventional example 2) that foot is set from bellying, when the rotary movement of moving contact member 1, can be reduced in notch 32, edge, periphery 11a part produce stress concentrate.Thereby, it is possible to suppress the crackle produced on moving contact member 1, the life-span of moving contact member 1 can be extended.Further, become the formation that skirt section 12 supports bellying 11, therefore with the situation that foot is not set and make foot extremely short situation (conventional example 1) compared with, the stroke of moving contact member 1 can be lengthened by skirt section 12.
In addition, moving contact member 1 of the present invention is, otch outer shape OS cut sides shape PS prolongation be connected to is formed as square (roughly square), therefore, when the rotary movement of moving contact member 1, the stress equilibrium produced in the part of notch 32, edge, periphery 11a can be made to disperse well.Thereby, it is possible to suppress the crackle produced on moving contact member 1 further, the life-span of moving contact member 1 can be extended further.And, with from bellying longer foot is set situation (conventional example 2) compared with, the maximum profile of moving contact member 1 (otch outer shape OS) can be made less, do not make the stroke of moving contact member 1 shorten and moving contact member 1 just can be made to become small-sized.
This otch outer shape OS is formed as, at the diameter of the dome than bellying 11
greatly, than the diameter of the maximum outer shape MS in skirt section 12
little partial configuration notch 32, but preferably at the diameter of dome
with the diameter of maximum outer shape MS
centre near slit configuration portion 32.Such as, at the diameter of the dome of bellying 11
near when being configured with notch 32, due to notch 32, stress becomes and easily concentrates, and the life-span of moving contact member 1 likely reduces.Such as, at the diameter of maximum outer shape MS
near when being configured with notch 32, the grounded part of the contact site 52 in skirt section 12 narrows, therefore contact site 52 likely unevenly the abrasion of ground connection, contact, the other side side (such as fixed contact) likely increase.
In addition, moving contact member 1 of the present invention is, skirt section 12 is in the mode roughly consistent with the tangential direction SD of the tangent line extended along dome radius direction DD, formed continuously from edge, the periphery 11a of bellying 11, situation about therefore connecting with having flex point with bellying 11 and skirt section 12 is compared, when the rotary movement of moving contact member 1, fulcrum during upset is not formed in this part, and stress can not focus on edge, the periphery 11a of bellying 11.Thereby, it is possible to suppress stress to concentrate the generation of the crackle of the moving contact member 1 caused further, the life-span of moving contact member 1 can be extended further.
The manufacture method of moving contact member 1, use stamping die to carry out the method for sharp processing and drawing processing to the flat sheet material formed by metal material, first, after having carried out cutting off (sharp processing) along the outer shape in skirt section 12 and notch 32, carry out with the plastic working bloated (drawing processing).Thus, compared with the situation of carrying out the sharp processing (profile is cut off) of skirt section 12 and notch 32 after processing with in the drawing of bellying 11, profile can be suppressed to cut off the generation of crackle of the bellying 11 caused and the generation of the strain of bellying 11 or distortion etc.
In addition, under the state that skirt section 12 does not bloat, under the state namely before the deep processing of sharp processing post-tensioning, the curve shape that the cut sides shape PS of notch 32 becomes rectilinear form or comparatively relaxes, but more preferably become slightly to the prominent shape of outside drum.The middle body of the cut sides shape PS of notch 32, due to drawing processing afterwards to bellying 11 lateral bend, therefore in order to the otch outer shape OS after making drawing process becomes square (roughly square), and this is become slightly to the prominent shape of outside drum.Thus, when the rotary movement of moving contact member 1, the stress equilibrium produced in the part of notch 32, edge, periphery 11a can be made to disperse well.Therefore, it is possible to suppress the crackle produced on moving contact member 1, the life-span of moving contact member 1 can be extended further.
According to the above, moving contact member 1 of the present invention is, skirt section 12 has the notch 32 of incision at the position of surrounding, and be formed with skirt section 12 continuously from edge, the periphery 11a of bellying 11, therefore compared with the situation being provided with notch with the part at bellying and the situation (conventional example 2) being provided with foot from bellying, when the rotary movement of moving contact member 1, can be reduced in notch 32, edge, periphery 11a part produce stress concentrate.Thereby, it is possible to suppress the crackle produced on moving contact member 1, the life-span of moving contact member 1 can be extended.Further, become the formation that bellying 11 is supported in skirt section 12, therefore with the situation that foot is not set and make foot extremely short situation (conventional example 1) compared with, the stroke of moving contact member 1 can be lengthened by skirt section 12.Therefore, it is possible to provide a kind of moving contact member 1, do not reduce the life-span of moving contact member 1, the stroke of moving contact member 1 can be lengthened.
In addition, when overlooking, the cut sides shape PS being formed in surrounding is, opposed cut sides shape PS is configured in parallel position each other and adjacent cut sides shape PS configures orthogonal position each other, and the otch outer shape OS therefore cut sides shape PS prolongation be connected to becomes square (roughly square).Therefore, when the rotary movement of moving contact member 1, the stress equilibrium produced in the part of notch 32, edge, periphery 11a can be made to disperse well.Thereby, it is possible to suppress the crackle produced on moving contact member 1 further, the life-span of moving contact member 1 can be extended further.
In addition, skirt section 12 is in the mode roughly consistent with the tangential direction SD of the tangent line extended along dome radius direction DD, formed continuously from edge, the periphery 11a of bellying 11, situation about therefore connecting with having flex point with bellying 11 and skirt section 12 is compared, when the rotary movement of moving contact member 1, fulcrum during upset is not formed in this part, and stress can not focus on edge, the periphery 11a of bellying 11.Thereby, it is possible to suppress stress to concentrate the generation of the crackle of the moving contact member 1 caused further, the life-span of moving contact member 1 can be extended further.
In addition, after having carried out cutting off (sharp processing) along the outer shape in skirt section 12 and notch 32, carried out with the plastic working bloated (drawing processing).Thus, compared with the situation of carrying out the sharp processing (profile is cut off) of skirt section 12 and notch 32 after processing with in the drawing of bellying 11, profile can be suppressed to cut off the generation of crackle of the bellying 11 caused, the generation of the strain of bellying 11 or distortion etc.
