[first execution mode]
Fig. 1 is the stereogram of the moving contact member 1 of explanation first embodiment of the invention.Fig. 2 is the figure of the moving contact member 1 of explanation first embodiment of the invention, and Fig. 2 (a) is a vertical view, and Fig. 2 (b) is an end view.Fig. 3 is the figure of the moving contact member 1 of explanation first embodiment of the invention, and 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 constitutes, and possesses: bellying 11, form by the metallic plate of conductivity, and can carry out rotary movement through pushing; And skirt section 12, form continuously from the 11a of outer peripheral edges portion of bellying 11.Thus, skirt section 12 forms with the 11a of outer peripheral edges portion of bellying 11 continuously, therefore becomes the formation that bellying 11 is supported.
As shown in Figure 2; Bellying 11 bloats to dome-shaped towards upper face side (Z1 direction shown in Figure 1); In the zone of the circle of the specified diameter
of dome, form with the regulation curvature bending; And in the zone between the circle of the maximum gauge
of the circle of specified diameter
and dome, also form with the regulation curvature bending.
In addition, the skirt section 12 with the 11a of outer peripheral edges portion of bellying 11 forms continuously is formed obliquely with predetermined angular.In this case, shown in Fig. 2 and Fig. 3 (b), skirt section 12 with the roughly consistent mode of tangential direction SD of the tangent line that extends along dome radial direction DD of the 11a of outer peripheral edges portion of bellying 11, form continuously from the 11a of outer peripheral edges portion of bellying 11.That is, skirt section 12 is connected with bellying 11 lenitively, on the boundary line between skirt section 12 and the bellying 11, does not have sweep, and the fulcrum in when upset is not formed on this part.
In addition, to shown in Figure 3, opposed position all around has by the notch 32 of otch clipping bellying 11 in skirt section 12 like Fig. 1, and the position beyond the notch 32 in skirt section 12 forms contact site 52.In addition, the notch 32 in skirt section 12 forms to bellying 11 sides and bloats (with reference to Fig. 2 (b)), so that become can the ground connection position position beyond the notch in skirt section 12 32.In addition, the notch 32 in skirt section 12 and the coupling part 42 between the contact site 52 connect agley.In addition; The maximum outer shape MS that overlooks of the contact site 52 in skirt section 12 forms the round shape of diameter
.In addition, the shape of the contact site 52 in skirt section 12 forms circular-arc, but also can form linearity.
Shown in Fig. 2 (a), the cut sides shape PS that overlooks of notch 32 becomes rectilinear form.Especially; Cut sides shape PS around being formed at does; Opposed cut sides shape PS is configured in the position that parallel position and adjacent cut sides shape PS are configured in quadrature each other each other, therefore cut sides shape PS is prolonged and the otch outer shape OS that connected becomes square (roughly square).In addition, the interval D S between the pair of notches portion 32 is bigger than the maximum gauge
of the dome of bellying 11.The cut sides shape PS of first embodiment of the invention almost is made up of rectilinear form, but also can be the curve shape that relaxes.
The moving contact member of the present invention 1 that so constitutes; To keep the mode of bellying 11 fully; Notch 32 around only on skirt section 12, forming forms skirt section 12 continuously from the 11a of outer peripheral edges portion of bellying 11, therefore with a part at bellying the situation of notch is set and compares from the situation (existing example 2) that bellying is provided with foot; When the rotary movement of moving contact member 1, the stress that can be reduced in the part generation of notch 32, the 11a of outer peripheral edges portion is concentrated.Thus, the crackle that produces on the moving contact member 1 can be suppressed at, the life-span of moving contact member 1 can be prolonged.And therefore, become the formation that bellying 11 has been supported in skirt section 12, with the situation that foot is not set and the extremely short situation of foot (existing example 1) is compared, through can the extend stroke of moving contact member 1 of skirt section 12.
In addition; Moving contact member 1 of the present invention does; Cut sides shape PS is prolonged and the otch outer shape OS that connected forms square (roughly square); Therefore when the rotary movement of moving contact member 1, the stress equilibrium that the part at notch 32, the 11a of outer peripheral edges portion is produced disperses well.Thus, the crackle that produces on the moving contact member 1 can be further be suppressed at, the life-span of moving contact member 1 can be further prolonged.And, compare with the situation that foot is set from bellying more longways (existing example 2), can make the maximum profile (otch outer shape OS) of moving contact member 1 less, the stroke of moving contact member 1 is shortened just moving contact member 1 is become small-sized.
This otch outer shape OS forms; Diameter
than the dome of bellying 11 is big, than the little part slit configuration portion 32 of diameter
of the maximum outer shape MS in skirt section 12, near but preferred slit configuration portion 32 centre of the diameter
of the diameter
of dome and maximum outer shape MS.For example; Near the diameter
of the dome of bellying 11, disposed under the situation of notch 32; Concentrate easily because notch 32 and stress become, the life-span of moving contact member 1 might reduce.For example; Near the diameter
of maximum outer shape MS, disposed under the situation of notch 32; The grounded part of the contact site 52 in skirt section 12 narrows down, thus contact site 52 unevenly the abrasion of ground connection, the other side's side contact (for example fixed contact) might increase.
In addition; Moving contact member 1 of the present invention does, skirt section 12 with the roughly consistent mode of tangential direction SD of the tangent line that extends along dome radial direction DD, form continuously from the 11a of outer peripheral edges portion of bellying 11; Therefore compare with the situation that bellying 11 and skirt section 12 are connected with having flex point; When the rotary movement of moving contact member 1, the fulcrum during upset is not formed on this part, and stress can not focus on the 11a of outer peripheral edges portion of bellying 11.Thus, the generation that stress is concentrated the crackle of the moving contact member 1 that causes can be further suppressed, the life-span of moving contact member 1 can be further prolonged.
The manufacturing approach of moving contact member 1; Be to use stamping die that the flat sheet material that is formed by metal material is carried out sharp processing and pull and stretch method for processing; At first along the skirt section 12 and the outer shape of notch 32 carried out cutting off (sharp processing) afterwards, followed the plastic working (pull and stretch processing) that bloats.Thus; Compare the generation that can suppress that profile cuts off that generation and the strain of bellying 11 of the crackle of the bellying 11 that causes perhaps are out of shape etc. with the situation of after the processing of the pull and stretch of bellying 11, carrying out the sharp processing (profile cut-outs) of skirt section 12 and notch 32.
In addition, under the state that does not bloat in skirt section 12, promptly under the state 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 relaxes, but more preferably become the prominent shape of drum a little laterally.The middle body of the cut sides shape PS of notch 32; It is bent because pull and stretch is afterwards processed to bellying 11 lateral bendings; Therefore in order to make the otch outer shape OS after pull and stretch is processed become square (roughly square), rouse prominent shape a little laterally and make it become this.Thus, when the rotary movement of moving contact member 1, the stress equilibrium that produces in the part of notch 32, the 11a of outer peripheral edges portion is disperseed well.Therefore, the crackle that produces on the moving contact member 1 can be suppressed at, the life-span of moving contact member 1 can be further prolonged.
According to the above; Moving contact member 1 of the present invention does; Skirt section 12 around the position have by the notch 32 of otch, and be formed with skirt section 12 continuously from the 11a of outer peripheral edges portion of bellying 11, therefore be provided with the situation of notch and compare from the situation (existing example 2) that bellying is provided with foot with a part at bellying; When the rotary movement of moving contact member 1, the stress that can be reduced in the part generation of notch 32, the 11a of outer peripheral edges portion is concentrated.Thus, the crackle that produces on the moving contact member 1 can be suppressed at, the life-span of moving contact member 1 can be prolonged.And, become the formation that bellyings 11 are supported in skirt section 12, therefore with the situation that foot is not set and the extremely short situation of foot (existing example 1) is compared, through can the extend stroke of moving contact member 1 of skirt section 12.Therefore, a kind of moving contact member 1 can be provided, the life-span of not reducing moving contact member 1, the stroke of the moving contact member 1 that can extend.
In addition; When overlooking; Cut sides shape PS around being formed on does; Opposed cut sides shape PS is configured in the position that parallel position and adjacent cut sides shape PS dispose quadrature each other each other, therefore cut sides shape PS is prolonged and the otch outer shape OS that connected becomes square (roughly square).Therefore, when the rotary movement of moving contact member 1, the stress equilibrium that produces in the part of notch 32, the 11a of outer peripheral edges portion is disperseed well.Thus, the crackle that produces on the moving contact member 1 can be further be suppressed at, the life-span of moving contact member 1 can be further prolonged.
In addition; Skirt section 12 with the roughly consistent mode of tangential direction SD of the tangent line that extends along dome radial direction DD; Form continuously from the 11a of outer peripheral edges portion of bellying 11, therefore compare, with having flex point when the rotary movement of moving contact member 1 with the situation that bellying 11 and skirt section 12 are connected; Fulcrum during upset is not formed on this part, and stress can not focus on the 11a of outer peripheral edges portion of bellying 11.Thus, the generation that stress is concentrated the crackle of the moving contact member 1 that causes can be further suppressed, the life-span of moving contact member 1 can be further prolonged.
In addition, along the skirt section 12 and the outer shape of notch 32 carried out cutting off (sharp processing) afterwards, followed the plastic working (pull and stretch processing) that bloats.Thus; Compare the generation that can suppress that profile cuts off that the strain of the generation of the crackle of the bellying 11 that causes, bellying 11 perhaps is out of shape etc. with the situation of after the processing of the pull and stretch of bellying 11, carrying out the sharp processing (profile cut-outs) of skirt section 12 and notch 32.
