The embodiment of invention
Following with reference to accompanying drawing, describe embodiments of the present invention in detail.Fig. 1 is the vertical view of the push-button switch of the present invention's the 1st execution mode, Fig. 2, Fig. 3 are respectively A-A cutaway view and the B-B cutaway views of Fig. 1, Fig. 4, Fig. 5 are respectively rearview, the end views of the push-button switch of embodiment of the present invention, and Fig. 6 is the concept map of the installment state of push-button switch on substrate.Fig. 7 is the enlarged drawing of inclination supression portion.And, in the present embodiment, all around by direction shown in Figure 1.
The push-button switch 1 of present embodiment, as shown in Figure 1 and Figure 2, on the shell 10 of the general square shape of opening concavity, be provided with above being shaped by insulating resin: the central fixed contact 21 of metallic plate system wherein has the central contact site 21a convex of being processed into, that be roughly circle; And the outside fixed contact 22 of metallic plate system, wherein have the former (central fixed contact) carried out on the symmetric position of clamping, be processed to the outside contact site 22a, the 22a that are roughly rectangle of convex equally.
And, central authorities' fixed contact 21 has as Fig. 1, shown in Figure 3: be conducted with central contact site 21a, intersect also conducting towards the linearly extended central linking part 21b of the leading flank 11a direction of shell 10 and with the linking part 21b of these central authorities approximate vertical, to the left and right side of shell 10 11c, the linearly extended brace 21c of 11d direction.Equally, outside fixed contact 22 has with each outside contact site 22a, 22a and is conducted, outside linking part 22b, the 22b that extends to trailing flank 11b direction and with this outside linking part 22b, 22b is conducted and to the linearly extended brace 22c of the left and right side of shell 10 11c, 11d.Each brace 21c, 22c are arranged to state parallel to each other basically.In addition, these each fixed contacts 21,22 are inlayed shaping by above-mentioned central contact site 21a, outside contact site 22a, 22a are exposed on the inner bottom surface of shell 10, and are fixed in the shell 10 by interior bag.
And, the splicing ear 23 that the two ends of each brace 21c, 22c are provided with below shell 10 13 four jiaos bight 12 respectively, exposes highlightedly.That is to say, on the left surface 11c and right flank 11d of shell 10, respectively 2 of splicing ears 23 are set respectively on position opposite one another.This splicing ear 23 landform shape that is in line that maintains the original state from the two ends of each brace 21c, 22c parallel with following 13 of shell 10 haply, and the end 23a of splicing ear 23 is crooked upward.
And the part that the splicing ear 23 of left and right side 11c, the 11d of shell 10 is given prominence to as shown in Figure 1, forms notch geometry, so that splicing ear 23 is arranged in the inboard as far as possible.Like this, when being welded to connect terminal 23, can be coated in more close inboard to solder(ing) paste 50 with solder(ing) paste 50, so, can reduce the special-purpose area when push-button switch 1 carries out mounted on surface on substrate 60, can improve the packing density on the substrate 60.
And in the present embodiment, shell 10 is square haply.But, be not limited only to this, for example also can be that circle waits other shapes.And, the splicing ear 23 of the present embodiment landform shape that is in line of keeping intact from the two ends of each brace 21c, 22c, but be not limited in this, for example other shapes such as the reclinate shape of two ends one end from each brace 21c, 22c also are not particularly limited.And the end 23a of splicing ear 23 is crooked upward, but not necessarily wants crooked like this, also can make end 23a keep rectilinear form.
At this, shell 10 following 13 as Fig. 4, shown in Figure 5.In the outside of the dummy line 70 that above-mentioned a pair of splicing ear 23,23 is opposite one another linked, near the position leading flank 11a of shell 10 and the trailing flank 11b, be provided with the spherical inclination supression portion of semicircle 16 each 2 respectively.That is to say, below shell 10, be provided with one-sided 2 on 13, add up to 4 inclination supression portions 16 and make it outstanding downwards.And each supression portion 16 of tilting is arranged on the position of mutual symmetry, and the depth of camber with shell 10 is identical highly haply.
Fig. 6 represents the installment state of push-button switch 1 on substrate 60.And Fig. 6 is a concept map, it is exaggerated to the warpage degree of shell 10, and, expressed designs simplification push-button switch 1.As shown in Figure 6, this inclination supression portion 16 is arranged on the outside following 13, that link the dummy line 70 of opposed a pair of splicing ear 23,23 of shell 10, one end that can prevent shell 10 when like this, on substrate 60 push-button switch 1 being carried out mounted on surface rises.That is to say, in the reflow stove of Reflow Soldering equipment, even make the splicing ear 23,23 of an end of push-button switch 1 pulled down owing to the surface tension of the solder(ing) paste 50 that has melted, the inclination supression portion 16,16 in the outside that is positioned at these splicing ears 23,23 is overlapped mutually with substrate 60, can suppress shell 10 and tilt.Therefore, the other end of shell 10 can not rise, even shell 10 has warpage, can be welded on the splicing ear 23 of push-button switch 1 securely on the substrate 60 yet.And as mentioned above, Fig. 6 is a concept map, and it is such in fact to become enlarged drawing shown in Figure 7.
And, as mentioned above, inclination supression portion 16 is arranged near the position of front and back sides 11a, 11b of shell 10, so can leave dummy line 70 certain distances, can suppress the inclination of push-button switch 1 more securely.
And, in the present embodiment, inclination supression portion 16 is arranged near the position front and back sides 11a, the 11b of shell 10, but the position of inclination supression portion 16 is not limited in this, also can be other Anywhere, so long as the outside of the dummy line 70 that links at a pair of splicing ear 23,23 that will be opposite one another gets final product.And the quantity of inclination supression portion 16 is decided to be one-sided 2, adds up to 4, but the quantity of inclination supression portion 16 is not limited only to this, for example also can be one-sided more than 3.Once more, the shape of inclination supression portion 16 also is not limited only to dome-shaped, also can be other shapes such as square, pyramid (rib vertebra) shape, it highly also not necessarily is substantially equal to the depth of camber of shell 10, so long as below the depth of camber of shell 10, and the inclination that its height can fully suppress push-button switch 1 gets final product.
Moreover, shell 10 as shown in Figure 3, Figure 4, the part beyond 13 the bight 12 below, promptly brace 21c, the 22c that does not link to each other with splicing ear 23 bury retaining part underground, a kind of step 14 that 23b gives prominence to downwards again below splicing ear 23 is set.That is to say, 13 the part that does not link to each other below having formed with splicing ear 23, and make it below 23b more leans on below splicing ear 23, locate a face.And, wish that this step 14 is formed on below the above 0.10mm of 0.03mm.And, relatively below splicing ear 23, form solder(ing) paste resettlement section 15 by this step 14 is set.
At this, in the installation of the push-button switch 1 of present embodiment, adopt method of surface mounting, promptly on the substrate 60 that has applied solder(ing) paste 50 on the precalculated position in advance, with solder(ing) paste 50 interim peg button switches 1, make it by in the reflow soldering equipment, utilize infrared ray or hot blast that solder(ing) paste 50 fusings are solidified.
When carrying out this mounted on surface, by forming above-mentioned solder(ing) paste resettlement section 15, push-button switch 1 is temporarily fixed on the solder(ing) paste 50 on the substrate 60, at this moment in this solder(ing) paste resettlement section 15, accommodate solder(ing) paste 50, so, push-button switch 1 can not be subjected to the influence of solder(ing) paste 50 and be disposed in the top higher than the precalculated position, simultaneously following 13 of shell 10 with substrate 60 mutually=contact, the arrangement states of push-button switch 1 is stablized.And, can weld securely, though simultaneously push-button switch 1 be pressed into carry out on the solder(ing) paste 50 temporary fixed, also can suppress solder(ing) paste 50 enter into than solder(ing) paste resettlement section 15 shell 10 more in the inner part following 13 or disperse towards periphery; Following 13 of push-button switch 1 float from substrate 60 in the time of preventing Reflow Soldering; Also can suppress the generation of solder ball.
At this, as mentioned above, step 14 is made into below the above 0.10mm of 0.03mm, be because the soldering tin powder particle diameter that is contained in the general solder(ing) paste is about 0.01mm～0.03mm, if step is below the 0.03mm, the particle diameter of soldering tin powder causes state labile is set greater than step 14 so.And, consider solder(ing) paste 50 thickness about coating 0.10mm～0.15mm usually, if step is more than the 0.10mm, step 14 is greater than the applied thickness of solder(ing) paste 50 so, when being arranged in push-button switch 1 on the substrate 60, the following 23b of splicing ear 23 might not contact with solder(ing) paste 50.That is to say,, can prevent following 13 come-ups of shell 10 conscientiously, substrate 60 and following 13 is contacted by step 14 being formed on below the above 0.10mm of 0.03mm.Simultaneously can be welded to connect terminal 23 securely.And, also can reduce the height dimension of the state that is provided with.Even adopting end 23a is under the situation of splicing ear 23 of linearity, also can similarly obtain above-mentioned effect.
But the condition below the above 0.10mm of 0.03mm of this step 14 is not limited only to this, also can freely adjust according to the particle diameter of the powder that is contained in the solder(ing) paste 50 and the applied thickness of solder(ing) paste 50.
And, shell 10 is as Fig. 1, dome-type elasticity travelling contact 30 with metallic plate system shown in Figure 2, its arrangement states is that the periphery lower end overlaps mutually with the outside contact site 22a of outside fixed contact 22, moreover, apply the flexible octagonal insulation film 40 of having of adhesive below and be fixed to the state that the top peristome to shell 10 hides, this insulation film 40 also is fixed on the central apex 30a of travelling contact 30, dome-type travelling contact 30 is remained on the precalculated position in the shell 10, simultaneously, prevent dust, scaling powders etc. invade on the make and break contact part.And, though present embodiment is the shape set of travelling contact 30 circular, be not specially to be defined as like this, for example also can adopt octangle, other shapes such as square.Insulation film 40 also is the same.If octangle not necessarily also can be circular, square etc.
Below describe the manufacture method of this push-button switch 1 in detail.Central authorities' fixed contact 21, outside fixed contact 22 and the splicing ear 23 that begins continuous formation thus, by metallic plate is carried out punch process and forms above-mentioned shape respectively, these central fixed contacts 21, outside fixed contact 22 utilize to be inlayed on the inner bottom surface that forming process is fixed to shell 10.At this moment, it is outstanding and expose that splicing ear 23 is fixed to below shell 10 13 four jiaos bight 12.And, shell 10 utilize insulative resin by mould by integrally formed.
At this, because the size of the warpage that produces on the shell 10 depends on: the various factorss such as gate location of the shape of each fixed contact 21,22 in the shape of shell 10, size, the shell 10, size, intensity, mould.So, at first do not form inclination supression portion 16 ground shaping shells 10.The mould of shaping shell 10, leading flank 11a or trailing flank 11b side at the shell 10 of moulding have the cast gate that is used to inject resin.Like this, by injecting resin from leading flank 11a side or trailing flank 11b side, can make the warp direction of shell 10 is certain orientation, becomes the direction that leading flank 11a side and trailing flank 11b side rise.Can make inclination supression portion 16 suppress the warpage of shell 10 effectively.And like this, the shell 10 of formation is in leading flank 11a side and trailing flank 11b side, has after formation from runner to carry out gate cutting and the section that generates, i.e. gate vestiges (not having diagram).
Like this, in fact shell 10 is tested shaping, check the warpage that much degree are arranged, and, make its by the reflow stove of Reflow Soldering equipment in the time, how many warpages increases, then, mould with inclination supression portion 16 corresponding positions on form the spherical recess of semicircle that needs the degree of depth.Like this, can form the inclination supression portion 16 of suitable height at the warpage of shell 10, an end that suppresses shell 10 when push-button switch 1 carries out mounted on surface reliably rises.And, in order to form this inclination supression portion 16, as long as on the correspondence position of mould, form recess, so be easy to form inclination supression portion.
And as mentioned above, shell 10 has step 14, has solder(ing) paste resettlement section 15 below splicing ear 23.Owing to have this solder(ing) paste resettlement section 15,, can keep high transfer printing (translocation so 13 gas is discharged easily below the shell 10
) precision, therefore, 13 precision below improving.
Moreover, because this solder(ing) paste resettlement section 15 is set, and so mould also has step, other part height of aspect ratio that the part that links to each other with splicing ear 23 forms.The character that resin has below mould and flow fast in the side, flow velocity slows down but resin flow is owing to meet this step, so the time difference that resin enters in the entire die reduces, the resin orientation that causes owing to the time of advent of resin is different is difficult for producing, and warpage is difficult for producing.
On the shell 10 that forms like this, arrange sheet metal is carried out punch process and the dome-type travelling contact 30 that forms, its periphery lower end is snapped on the outside contact site 22a of outside fixed contact 22, moreover, fix insulation film 40 from above, so that the top peristome of shell 10 is hidden, constitute push-button switch 1.
At last, describe the action of the push-button switch 1 of embodiment of the present invention in detail.Push-button switch 1 utilizes solder(ing) paste 50 that splicing ear 23 is welded in the predetermined wiring portion, thereby is fixed on the precalculated position of substrate 60.In the push-button switch 1 on being fixed on substrate 60 like this, insulation film 40 from roughly pushing with the perpendicular top of the substrate that welded 60, is pushed the central apex 30a of dome-type travelling contact 30 downwards by having flexible insulation film 40 downwards.And when this pressing force reached certain value, travelling contact 30 action of reversing touched on the central contact site 21a of the central fixed contact 21 that is arranged on the shell 10 the inside of its central apex 30a.
Like this, central fixed contact 21 and outside fixed contact 22 carry out conducting by dome-shaped travelling contact 30, become the state of switch connection, form conducting between the predetermined wiring portion of the substrate 60 that is connected with each splicing ear 23.
Then, if remove pressing force to insulation film 40, the elastic restoring force of then dome-type travelling contact 30 dependence itself and return to original state turns back to the state of switch disconnection.
In the push-button switch 1 of present embodiment, although it is so from accepting repeatedly the load of pushing with the perpendicular top of the substrate 60 of welding haply, but because following 13 the contacting with substrate 60 of shell 10, so can not produce undesirable deflection at the central portion of push-button switch 1.
And, at this, the situation of directly pushing insulation film 40 has been described.But also can the operating knob of reservation shape be set on the top of insulation film 40 for ease of carrying out pressing operation, push travelling contact 30 by this operating knob and insulation film 40 according to the difference of occupation mode.
The effect of invention
If employing the present invention, the void that then links at the opposed splicing ear below shell Intend the outside of line, overlap mutually to suppress the inclination that shell tilts with substrate when being provided with for installation Supression section. So, even by solder(ing) paste the splicing ear of one end of press button is drawn Power also can utilize inclination supression section to suppress shell. Can prevent like this other end of shell Rise, can be welded to connect securely terminal.
And, if adopt the present invention, protruding with the roughly the same height of shell depth of camber then Shape forms the inclination supression section that is arranged on below the shell, so, inclination supression section easily and Shell overlaps mutually, can suppress more effectively shell.
Moreover if adopt the present invention, then shell is wrapping in resin in fixed contact and the splicing ear In, in the side on the one side that is provided with inclination supression section gate vestiges is arranged, so, can be more firm Ground keeps fixed contact and splicing ear, simultaneously, can make the side one that is provided with inclination supression section Side produces the shell warpage with rising, can make inclination supression section effectively suppress the shell warpage.
And, if adopt the present invention, then the inclination supression section below the shell is not arranged on and connects Near the side of connecting terminal, so inclination supression section is arranged on to leave opposed splicing ear is advanced On the position of the dummy line of joining line, can conscientiously suppress thus the inclination of shell.
