- the position can be fixed as long as there is no deviation so that a part of the contact portion of the housing 1 does not enter the groove.
- the pattern shape of the groove 22a does not match the shape of the contact portion of the housing 1, for example, as shown in FIGS. 13A and 13B, the shape of the contact portion of the housing 1 is the groove 22a. Even if the shape is smaller than the pattern shape of the above, the position can be fixed as long as a part of the contact portion of the housing 1 is inserted even in a part of the groove.
- the groove 22a is formed at a position where the contact portion of the housing 1 straddles along the groove, so that the accuracy of the position adjustment is improved. Not only is it significantly improved, but the position can be fixed more firmly by further increasing the joint area. Further, a bonding agent such as solder and an adhesive is not required, and it is possible to reduce the bonding agent cost, reduce the bonding agent management cost, omit the printing work and the coating work, and shorten the bonding time.
- Embodiment 6 In the fifth embodiment, the groove 22a is formed by one pattern, but in the sixth embodiment, the case where the groove is formed by a plurality of patterns will be described.
- FIGS. 14A and 14B are views showing a housing fixed on a substrate by the method of fixing the housing according to the sixth embodiment of the present application.
- 14 (a) is a plan view
- FIG. 14 (b) is a cross-sectional view taken along the line BB of FIG. 14 (a).
- the housing 1 has a pattern of double grooves 32a dug in the surface of the substrate 2 and one of the contact portions of the housing 1 with the substrate 2. The portion is embedded, the embedded portion 31a is formed, and the portion is fixed to the substrate 2.
- the substrate 2 has two patterns of grooves 32a having a rectangular or square cross-sectional shape in the groove direction.
- the two grooves 32a are formed at positions where the contact portion of the housing 1 straddles the grooves.
- the total width of the two grooves 22a needs to be narrower than the wall thickness of the contact portion of the housing 1.
- the two grooves 22a may penetrate the substrate 2.
- the number of grooves 32a is two, but the present invention is not limited to this, and there may be three or more grooves.
- As a method of forming a groove laser processing, etching, blast processing, a router, a drill, an end mill or the like is used. Grooves may be formed by the plating pattern on the surface of the substrate.
- the cross-sectional shape of each of the two grooves 32a in the groove direction is rectangular or square, but the present invention is not limited to this.
- the cross-sectional shape of each of the two grooves in the groove direction is a parallelogram (FIG. 15 (a)), that is, the side of the groove bottom rather than the side of the substrate surface.
- a quadrangle with a longer length (FIG. 15 (b)), a pentagon or more polygon (FIG. 15 (c)), a U-shape (FIG. 15 (d)), a circle (FIG. 15 (e)), and a V-shape (FIG. 15). (F)) may be used.
- the method of fixing the housing according to the sixth embodiment is the same as the method of fixing the housing according to the first embodiment, and the description thereof will be omitted.
- the position adjustment can be fixed as long as there is no deviation so that a part of the contact portion of the housing 1 does not enter the groove.
- the two grooves 22a are formed at the positions where the contact portions of the housing 1 straddle along the grooves. Not only the accuracy of the position adjustment is remarkably improved as compared with the case where the corresponding protrusions are fitted and positioned, but also the position can be fixed more firmly by further increasing the joint surface property. Further, a bonding agent such as solder and an adhesive is not required, and it is possible to reduce the bonding agent cost, reduce the bonding agent management cost, omit the printing work and the coating work, and shorten the bonding time.
