In addition, in the rear surface (diagram left side) of the 3g of edge portion of driving body 3 slide block 4 that is made of metallic plate is installed.
And the 3g of edge portion of this driving body 3 is positioned at the recess 1a of case member 1, and the rear end of the 3b of tube portion (diagram left side) inserting hole 1c, thereby this driving body 3 can be supported by case member 1 rotatably.In addition,, be installed on the slide block 4 and conductive pattern (conductive plate) 2 contact separations of driving body 3, constituted the pulse switch that carries out the switching of contact like this by driving body 3 rotations.
In addition, the sheet material 5 of the ring-type that is made of rubber-like metallic plate or plastics etc. is configured in the front of case member 1 and the 3g of edge portion, makes it stop up the recess 1a of case member 1.
And, on sheet material 5, be formed with tongue-shaped flexure strip 5a, by driving body 3 rotation, the jog 3h clutch mutually of flexure strip 5a and driving body 3 with respect to the spinning movement of driving body 3, is attended by the click sense of touch of rattling away.
As mentioned above, the driving body 3 by slide block 4 is installed, the case member 1 and the sheet material 5 of conductive pattern (conductive plate) 2 have been installed, have been constituted the i.e. pulse switch for example of rotary electrical accessory D.Described rotary electrical accessory D is not limited to pulse switch, for example also can be variable resistance etc.
In addition, the installing component that is made of metallic plate is the flat part 6a that parts of bearings 6 is formed with flat condition, and be formed with: carry out pull and stretch processing etc. by central portion, give prominence to and be cylindrical portion 6b cylindraceous and the 6c of bearing portion to the diagram right with aperture and the height dimension of regulation to flat part 6a.In addition, move, between cylindrical portion 6b and the 6c of bearing portion, be formed with the tapering 6d of predetermined angular for operating axis 7 described later is successfully slided.
And, the large diameter the first axle part 7e of operating axis 7 described later can almost not be embedded in the 6c of bearing portion of tubular (cylindric) loosely, can rotate and can move slidably at axis direction (arrow B direction), and the 6c of bearing portion between have small gap.
In addition, cylindrical portion 6b is formed with the big aperture, aperture than the 6c of bearing portion, even the first axle part 7e of operating axis described later 7 is owing to high temperature expands, and this first axle part 7e between also have the gap.
In addition, as shown in Figure 1, parts of bearings (installing component) 6 is formed with: can elasticity (snap) be limited to the elastic foot 6e on printed base plate (not shown) etc.; And the fixed claw 6f that forms up and down in the diagram of this elastic foot 6e.
And, by with fixed claw 6f to back bending at the insulator described later 10 of the rear of case member 1 configuration, make parts of bearings 6 and case member 1 integrated.At this moment, sheet material 5 is clamped between the flat part 6a of the sidewall 1d of case member 1 and parts of bearings 6.
In addition, the operating axis 7 of inserting logical cylindrical portion 6b and the 6c of bearing portion is made of plastic molded part, has filled the glass fibre of ormal weight in order to improve intensity in resin material and forms processing.
Therefore, excelling in abrasion resistance even operating axis 7 is carried out repeatedly rotary manipulation or bulldozing operation, also can prevent the inconvenience that the wearing and tearing owing to rotational slide portion produce.
As Fig. 2, shown in Figure 3, described operating axis 7 is in the leading section side (not operation portion side) of left part, on axis S, be formed with the spring press section 7a of thin axle, about the diagram of this spring press section 7a, cut groove 7b along what axis S direction was formed with the width dimensions of regulation and depth dimensions.
In addition, cut about diagram groove 7b, spring press section 7a clipping, be formed with a pair of installation foot 7c.And, the tab-like diagram left side that is formed in installation foot 7c of spring press section 7a.
In addition, on the diagram right side of operating axis 7 (operating portion side), be formed with the operating portion 7d of the cross section D word shape that the operating handle (not shown) has been installed, central portion at operating axis 7 is formed with the first axle part 7e, described the first axle part 7e can almost not be embedded on the 6c of bearing portion of parts of bearings 6 loosely, can rotate also and can move slidably, and have small gap between the 6c of bearing portion.Be formed with the second axle part 7f that can be embedded in the 6c of bearing portion on the diagram right side of this first axle part 7e (operating portion side), the diameter of described the second axle part 7f is thinner than the first axle part 7e, has than the big gap, gap between the first axle part 7e and the 6c of bearing portion.That is, the first axle part 7e is the axial region of the thick diameter bigger than the diameter of the second axle part 7f.
In addition, on the second axle part 7f, be formed with conical surface 7g on Zhou Fangxiang, described conical surface 7g is along with leaving to the operating portion side on diagram right side from the first axle part 7e, and diameter slowly attenuates.This conical surface 7g has constituted the part of the second axle part 7f, forms continuously from the first axle part 7e.And, be urged operation to the operating axis 7 of arrow B direction when the arrow A direction resets, the guide portion when this conical surface 7g becomes the first axle part 7e and the 6c of bearing portion tabling.
In addition, at operating axis 7, be formed with end difference 7h at the diagram left surface of the first axle part 7e, by this end difference 7h, to arrow B direction bulldozing operation operating axis 7 time, end difference 7h becomes the limiting section with the tube portion 3b end butt of driving body 3.
In addition, shown in Fig. 3 C, operating axis 7 is formed with in the diagram right side of operating portion 7d to be shaped and adds the filling oral area 7j in man-hour.
Described operating axis 7 is provided with by the right side at the big operating portion 7d of diameter dimension and fills oral area 7j, the orientation of filling the glass fibre of ormal weight in resin material can be arranged in the almost parallel with axis S, can improve the intensity of operating axis 7.
Because such operating axis 7 very ninor feature has become gap between the 6c of bearing portion of the first axle part 7e of thick diameter and parts of bearings 6, so the first axle part 7e of the operating axis 7 of initial condition, with the direction of axis S quadrature on almost be not embedded in the 6c of bearing portion loosely, can rotate and can move slidably along with bulldozing operation.
That is, the first axle part 7e of the operating axis 7 of the initial condition before arrow B direction bulldozing operation can rotate and the mobile state that can slide, has small gap with the 6c of bearing portion and is embedded in the 6c of bearing portion of parts of bearings 6.
In addition, as shown in Figure 5, stroke operating axis 7, that the switching circuit from initial condition shown in Figure 2 to push-button switch P described later is opened is size C.In addition, operating axis 7 when the switching circuit of push-button switch P described later is opened is extracted the first axle part 7e from the 6c of bearing portion to diagram left side (not operation portion side), the size from the 6c of bearing portion at this moment to the first axle part 7e, shown in imaginary line among Fig. 5 (dotted line), be the dimension D littler than size C.
And operating axis 7 returns the stroke of size C to the arrow A direction, thereby can make the first axle part 7e be embedded in the 6c of bearing portion reliably by removing the bulldozing operation of arrow B direction.
In addition, when operating axis 7 is assembled in driving body 3, the spring press section 7a side arrows B direction of operating axis 7 is moved, and insert the hole 3a of the 3b of tube portion of driving body 3.
So the installation foot 7c of operating axis 7 is connected to the inner face of fastener 3f, and, if to arrow B direction push operation axle 7, the direction bending that then hook-shaped installation foot 7c cuts groove 7b to constriction, and the hole 3a of the part by having formed fastener 3f.
Then, the installation foot 7c of the hole 3a of the part by having formed fastener 3f, because the elastic return of self is to original state, unci elasticity is limited to the fastener 3f of driving body 3.So, limited operating axis 7 coming off to the arrow A direction.
In addition, be limited the spring press section 7a of the operating axis 7 that comes off from driving body 3 by installation foot 7c, insert the aperture 3d of the logical 3c of seat portion.
Thus, limited loosening appearance spring press section 7a side and direction axis S quadrature, and can on the arrow B direction, slide and move.
The operating axis 7 that engages with driving body 3 like this, operating portion 7d inserts the hole (not shown) and the parts of bearings 6 of sheet material 5 from cylindrical portion 6b side, operating portion 7d is outstanding from the 6c of bearing portion, and the driving body 3 that slide block 4 has been installed is housed among the recess 1a of case member 1.And, (left side among Fig. 2) configuration leaf spring 11 described later and insulator 10 at the rear of case member 1, under this state, by with the fixed claw 6f of parts of bearings 6 to the back of insulator 10 lateral buckling, carry out the assembling of each parts.
The operating axis 7 that is assembled into like this, the initial condition before the bulldozing operation, when arrow B direction bulldozing operation, collide in the tube portion 3b end of end difference 7h and driving body 3, and this slip is moved and is stopped.In addition, for the operating axis 7 of removing bulldozing operation and returning to the arrow A direction, hook-shaped installation foot 7c is blocked by fastener 3f, and the stroke of 7 mobile size C of slip of operating axis moves and can not continue to slide.
In addition, the rear portion in the diagram of case member 1 left side is equipped with the insulator 10 of having buried fixed contact 8,9 underground, in the internal configurations of this insulator 10 the dome-type leaf spring 11 that is made of metallic plate as moving contact is arranged.
The periphery of described leaf spring 11 and fixed contact 9 are permanently connected to, and the spring press section 7a butt of its central portion and operating axis 7 is always to arrow A direction elasticity bulldozing operation axle 7.
And, having constituted push-button switch P by insulator 10 and leaf spring 11 with fixed contact 8,9, this push-button switch P and rotary electrical accessory D are arranged and are arranged on the axis S.
The operation of the rotary electrical accessory of above-mentioned such band push-button switch that constitutes is described then.If the operating portion 7d to operating axis 7 is rotated operation, then driving body 3 rotates along with the rotation of operating axis 7, is installed on sliding shoe 4 and conductive pattern (conductive plate) 2 slide relative on the driving body 3, and operating rotary electrical accessory D thus is pulse switch.
In addition, if the operating axis 7 to Fig. 1, initial condition shown in Figure 2 on the arrow B direction carries out bulldozing operation, then the spring press section 7a of operating axis 7 front ends pushes the central portion of leaf spring 11, and the leaf spring 11 with elastic force is reverse, and the inner surface of the central portion of leaf spring 11 contacts with fixed contact 8.
Thus, fixed contact 8 and 9 is via leaf spring 11 conductings, and the switching circuit of push-button switch P is unlocked.
In the bulldozing operation of described operating axis 7, the first axle part 7e that is embedded in the initial condition of the 6c of bearing portion extracts and is positioned at cylindrical portion 6b from the 6c of bearing portion, and then the gap between the first axle part 7e and the cylindrical portion 6b becomes bigger than the first axle part 7e and the gap between the 6c of bearing portion of initial condition.
But, operating axis 7 is carried out bulldozing operation and during the switching circuit of the switch P of releasing the button, as shown in Figure 7, the conical surface 7g of the second axle part 7f is positioned at the 6c of bearing portion, becomes conical surface 7g and the chimeric state of the 6c of bearing portion.At this moment, though the gap between conical surface 7g and the 6c of bearing portion is bigger than the first axle part 7e and the minim gap between the 6c of bearing portion of initial condition, gap during than bulldozing operation shown in Figure 7, between the first axle part 7e and the cylindrical portion 6b is little.Therefore, the loosening belt in the time of can suppressing that operating axis 7 carried out bulldozing operation becomes big for the not harmony sense of the operation sense of touch of bulldozing operation.
In addition, when operating axis 7 is carried out bulldozing operation,, push the spring press section 7a of a side of leaf spring 11, because the aperture 3d of driven member 3 guiding is become flexible so also be difficult to generation in spring press section 7a side even loosening in the generation of operating axis 7d side
Therefore, spring press section 7a always pushes the roughly the same position in the substantial middle portion of leaf spring 11.
In addition, after the switching circuit that makes push-button switch P was opened, if remove the bulldozing operation of the arrow B direction of operating axis 7, then owing to the elastic force of leaf spring 11, operating axis 7 returned to the arrow A direction.
Then, leaf spring 11 separates with fixed contact 8, and the switching circuit of push-button switch P becomes closed condition, and installation foot 7c blocked by fastener 3f, thereby operating axis 7 moves to the slip of arrow A direction and stops.
The rotary electrical accessory of above-mentioned band push-button switch of the present invention like this, if to the stroke of the operating axis 7 bulldozing operation size C that are in initial condition and the switching circuit of the switch P of releasing the button, then the first axle part 7e of operating axis 7 only breaks away from dimension D from the 6c of bearing portion of parts of bearings 6, be positioned at the aperture than the big cylindrical portion 6b of the 6c of bearing portion, have the gap (play) of size to a certain degree with cylindrical portion 6b.
Therefore, the rotary electrical accessory of band push-button switch of the present invention is used in vehicle that for example variations in temperature is big etc., even vehicle interior temperature becomes the high temperature more than 50 ℃, operating axis 7 expands, when removing the bulldozing operation of operating axis 7, also can make operating axis 7 return dimension D at least by the elastic force of leaf spring 11 to the arrow A direction.Therefore, the switching circuit of the push-button switch P that has opened cuts out.
In addition, when bulldozing operation since the conical surface 7g that is provided with than the thin the second axle part 7f of the first axle part 7e at diameter be positioned at the 6c of bearing portion carry out chimeric, so conical surface 7g pilot operationp axle 7 moves to the arrow A direction easily and successfully.And, by the tapering 6d that between the 6c of bearing portion of parts of bearings 6 and cylindrical portion 6b, is provided with, also can guide conical surface 7g, the first axle part 7e of the second axle part 7f, operating axis 7 is more successfully moved to the arrow A direction.Therefore, by conical surface 7g, tapering 6d are set, the switching circuit of push-button switch P cuts out.
