In addition, the substrate housing structure 1 may also be directly provided in the electronic device.

[0081] Electronic devices are, for example, field devices. Field devices are devices used in complete sets of equipment.

[0082] The substrate housing structure 1 includes a substrate 2, a housing 3, and substrate wiring 4. The housing 3 includes a first portion 3a and a second portion 3b connected to the first portion 3a.

[0083] The first part 3a has a metal box body 5, an elastic annular buffer component 6, an annular first sealing component 7 and an annular second sealing component 8. The buffer component 6, the first sealing component 7 and the second sealing component 8 are held by the box body 5. The first part 3a has a connector component 9 and a joint component 11, and the joint component 11 is connected to the connector component 9 through a first threaded portion 10. The connector component 9 has a first sealing component 7. The joint component 11 has a buffer component 6 and a second sealing component 8. The box body 5 is composed of a metal portion of the connector component 9 except the first sealing component 7, and a metal portion of the joint component 11 except the buffer component 6 and the second sealing component 8.

[0084] The second part 3b is in the shape of a topped cylinder with one end closed, and the other end is connected to the coupling member 11 through the second threaded portion 12, and is formed of a resin material connected from one end to the other end. The buffer member 6 is formed of, for example, rubber, an elastomer, or a sponge. The wiring 4 for the substrate has a first connector 4a held by the coupling member 11, and a cable 4b connected to the first connector 4a. The connector member 9 is connected to the electronic device for adding a wireless communication function.

[0085] The part of the connector member 9 that constitutes the case body 5 is composed of two members. The part of the joint member 11 that constitutes the case body 5 is composed of one member. The second portion 3b is composed of one member.

[0086] The substrate 2 has a substrate body 2a and a second connector 2b, which is mounted on the substrate body 2a and connected to the first connector 4a. In addition, the substrate 2 has an antenna for wireless communication (not shown). The substrate 2 has a thickness, a width, and a length that define a thickness direction Dt, a width direction Dw, and a length direction Dl that are perpendicular to each other.

[0087] The second portion 3b has a cylindrical peripheral wall 13 centered on an axis O parallel to the longitudinal direction and an end wall 14 closing one end of the peripheral wall 13. The first threaded portion 10 and the second threaded portion 12 are formed so as to be threadedly connected by rotation operation centered on the axis O.

[0088] In addition, in this embodiment, for convenience of explanation, the direction along the axis O is also referred to as the up-down direction, and the direction along the axis O from the first portion 3a toward the second portion 3b ( Figure 1 The direction opposite to the above is also called the below, the direction of rotation around the axis O is also called the circumferential direction, and the direction along the straight line perpendicular to the axis O is also called the radial direction.

[0089] The first sealing member 7 is disposed adjacent to the inner side of the first threaded portion 10 to prevent water from entering the internal space S of the substrate storage 2 through the first threaded portion 10. The second sealing member 8 is disposed adjacent to the outer side of the second threaded portion 12 to prevent water from entering the internal space S through the second threaded portion 12. In this way, the substrate storage structure 1 has a waterproof structure that prevents water from entering the internal space S. The first sealing member 7 and the second sealing member 8 are each formed of, for example, rubber or an elastomer.

[0090] The first threaded portion 10 is composed of a male thread provided on the outer peripheral surface of the connector component 9 and a female thread provided on the inner peripheral surface of the joint component 11. The joint component 11 is connected to the connector component 9 via the first threaded portion 10 when arranged above the connector component 9.

[0091] The second threaded portion 12 is composed of a male thread provided on the outer circumference of the coupling member 11 and a female thread provided on the inner circumference of the other end of the second portion 3b. The second portion 3b is connected to the coupling member 11 by the second threaded portion 12 when arranged above the coupling member 11.

[0092] The connector component 9 is in a substantially cylindrical shape with the axis O as the center. The coupling component 11 is in a cylindrical shape with the axis O as the center. The coupling component 11 has: a lower peripheral wall 15 having a female thread of the first threaded portion 10 at the lower end and a male thread of the second threaded portion 12 at the upper end; and a cylindrical wall 16 extending upward from the upper end of the lower peripheral wall 15 and having an outer diameter smaller than that of the lower peripheral wall 15.

[0093] A gap G is formed between the outer peripheral surface of the cylindrical wall 16 and the inner peripheral surface of the second portion 3b, and the buffer component 6 is arranged in the gap G. The lower surface of the buffer component 6 is supported by the upper surface of the lower peripheral wall 15. The first peripheral groove 16a is provided at the lower end of the outer peripheral surface of the cylindrical wall 16, and the inner peripheral surface of the buffer component 6 is supported by the outer peripheral surface of the cylindrical wall 16 in the first peripheral groove 16a. Therefore, the buffer component 6 is retained by being engaged with the engaging component 11. The buffer component 6 has a predetermined rectangular cross-sectional shape along the circumferential direction.

[0094] like Figure 3 , Figure 4 as well as Figure 6 As shown, the cylindrical wall 16 has a pair of slits 17 extending from the upper end surface of the cylindrical wall 16 along the length direction D1. The lower end of the substrate 2 is inserted into each slit 17, and the lower end surface of the substrate 2 is supported by the upper surface of the buffer member 6. In addition, by the insertion of the substrate 2, the second connector 2b held on the substrate 2 is connected to the first connector 4a held on the first part 3a. The position of the lower end of the substrate 2 is restricted on both sides of the thickness direction Dt by each slit 17.

[0095] The outer peripheral surface of the cylindrical wall 16 has a second peripheral groove 18 that crosses the pair of slits 17 and extends in the circumferential direction. The substrate receiving structure 1 has an annular retaining member 19, which is arranged in the second peripheral groove 18 to retain the substrate 2 in a state of being inserted into the pair of slits 17. The annular retaining member 19 has elasticity, for example, formed of rubber or an elastomer. At the lower end of the substrate 2, notches 2c are respectively provided on both end surfaces in the width direction Dw, and the annular retaining member 19 is arranged in each notch 2c.

[0096] Therefore, the substrate 2 can be held in the first part 3a by inserting the substrate 2 into the pair of slits 17 of the first part 3a and then assembling the annular holding member 19. Alternatively, the annular holding member 19 may be assembled in advance and elastically deformed when the substrate 2 is inserted into the pair of slits 17 to assemble the substrate 2.

[0097] like Figure 5 As shown, the second portion 3b has a cylindrical width-direction limiting wall 20, and the width-direction limiting wall 20 has a conical inner peripheral surface 20a whose diameter increases toward the top end (lower end). The width-direction limiting wall 20 extends downward from the end wall 14. In addition, the second portion 3b has a protrusion 21 extending downward from the end wall 14 on the inner side of the width-direction limiting wall 20. The protrusion 21 is in a columnar shape with the axis O as the center.

[0098] Therefore, the second part 3b is assembled to the first part 3a in a state where the substrate 2 is assembled through the second threaded portion 12, whereby the lower end of the protrusion 21 can press the substrate 2 from above and the inner peripheral surface 20a of the width-direction limiting wall 20 can press the substrate 2 from both sides of the width direction Dw. Thus, the position of the upper end of the substrate 2 in the width direction Dw can be limited. In addition, at this time, since the substrate 2 can elastically deform the buffer component 6 and sink downward, even if the deviation in the size of the substrate 2 in the length direction Dl is large, the deviation can be absorbed by the elastic deformation of the buffer component 6, and the position of the substrate 2 in the length direction Dl can be limited. Therefore, as Figure 3 , Figure 6 As shown in FIG. 1 , each slit 17 extends below the position of the upper surface of the buffer member 6 before elastic deformation.

[0099] By assembling like this, Figure 1 As shown, the substrate 2 can be housed in the internal space S of the housing 3. The internal space S is formed by a portion including the inner surface of the second portion 3b, the inner peripheral surface of the joint member 11, and the upper surface of the connector member 9.

[0100] As described above, the box body 3 restricts the position of the substrate 2 on both sides in the thickness direction Dt, on both sides in the width direction Dw, and on both sides in the length direction Dl. Figure 3 , Figure 5 as well as Figure 6 As shown, the box body 3 has: a thickness direction restriction portion 22 that restricts the position of the substrate 2 on both sides of the thickness direction Dt; a width direction restriction portion 23 that restricts the position of the substrate 2 on both sides of the width direction Dw; and a length direction restriction portion 24 that restricts the position of the substrate 2 on both sides of the length direction Dl. In addition, the first portion 3a has the thickness direction restriction portion 22 and a part of the length direction restriction portion 24, and the second portion 3b has the width direction restriction portion 23 and another part of the length direction restriction portion 24.

[0101] More specifically, the thickness direction limiting portion 22 has: a first abutting surface 22a capable of abutting against the substrate 2 from one side of the thickness direction Dt; and a second abutting surface 22b capable of abutting against the substrate 2 from the other side of the thickness direction Dt. The width direction limiting portion 23 has: a first abutting surface 23a capable of abutting against the substrate 2 from one side of the width direction Dw; and a second abutting surface 23b capable of abutting against the substrate 2 from the other side of the width direction Dw. A portion of the length direction limiting portion 24 has a first abutting surface 24a capable of abutting against the substrate 2 from one side of the length direction Dl, and another portion of the length direction limiting portion 24 has a second abutting surface 24b capable of abutting against the substrate 2 from the other side of the length direction Dl.

[0102] The thickness direction restriction portion 22 is formed by a pair of slits 17. A portion (first contact surface 24a) of the length direction restriction portion 24 is formed by the buffer member 6. The other portion (second contact surface 24b) of the length direction restriction portion 24 is formed by the protrusion 21. The width direction restriction portion 23 is formed by the inner peripheral surface 20a of the width direction restriction wall 20.

[0103] According to the substrate storage structure 1 of the present embodiment, since the position of the substrate 2 can be restricted and the substrate 2 can be firmly held on both sides of the thickness direction Dt, the width direction Dw, and the length direction Dl only by the box body 3, it is not necessary to flow the potting material into the internal space S and solidify it, and simple assembly can be achieved. In addition, according to the present embodiment, although the potting material is not required, the potting material can be additionally used for the purpose of further strengthening.

[0104] The above-described embodiment is an example of the present invention, and various modifications are possible.
