EMBODIMENT OF THE INVENTION Hereinafter, the example of embodiment of the small diameter coaxial electric wire harness with a board | substrate which concerns on this invention is described, referring drawings.

(First Embodiment)

First, the small diameter coaxial wire harness of 1st Embodiment is demonstrated.

As shown to FIG. 1 and FIG. 2, in this embodiment, between two board | substrates 11 and 12 which are arrange | positioned up and down and horizontally moved back and forth (left-right direction of FIG. 1 and FIG. 2), there are a plurality (20). A small diameter coaxial cable harness (small diameter coaxial wire harness) 20 including a small diameter coaxial cable (small diameter coaxial wire) 24 to be described later is connected.

The board | substrates 11 and 12 are respectively assembled in the casing 13 and 14 which slide relatively of apparatuses, such as the mobile telephone 10 shown in FIG. 3, for example. In this cellular phone 10, a display is provided in one casing 13, and a key operation part is provided in the other casing 14. As shown in FIG.

FIG. 1 shows a state in which both ends 21a and 21b of the small diameter coaxial cable harness 20 are closest to each other when the casings 13 and 14 slide in a straight line shape. FIG. 2 shows that both ends 21a and 21b are closed. It is the farthest state. The horizontal movement distance of the board | substrates 11 and 12, ie, the slide stroke L between casings 13 and 14, is about 30 mm-80 mm, for example. In addition, in this embodiment, the slide stroke L is 60 mm.

As shown in FIG. 4, both terminals of the small-diameter coaxial cable harness 20 are attached to the connectors 25 to perform star formation to facilitate connection with the substrates 11 and 12. In the small diameter coaxial cable harness 20, a plurality of small diameter coaxial cables 24 are bundled together by a braided sleeve (a sleeve having flexibility) 23 except for both ends 21a and 21b. In addition, in FIG. 4, FIG. 1, etc., although the longitudinal direction of the connector 25 is arrange | positioned in the direction along the slide direction of the casing 13, 14, it does not matter other than this direction. For example, the longitudinal direction of the connector 25 may be arrange | positioned in the direction orthogonal to the slide direction of the casing 13,14.

The small diameter coaxial cable 24 is a structure which has a center conductor, an internal insulator, an outer conductor, and an outer sheath from the center to the outer side in the radial direction orthogonal to a central axis, and each end part 21a, 21b. In the terminal processing, the outer conductor, the inner insulator, and the center conductor are exposed stepwise by a predetermined length. In addition, the small diameter coaxial cable harness 20 may include a small diameter insulated cable having no external conductor, in addition to the plurality of small diameter coaxial cables. In addition, in the figure, the number of small diameter coaxial cables 24 is shown small and simplified.

As the small diameter coaxial cable 24, it is preferable to use an ultrafine coaxial cable that is thinner than AWG42, for example, by the standard of AWG (American Wire Gauge). Thereby, the small diameter coaxial cable harness 20 is easy to bend, and the resistance at the time of sliding both board | substrates 11 and 12 can be made small. In addition, when the small diameter coaxial cable harness 20 is formed by tying a plurality of small diameter coaxial cables 24, the diameter of the small diameter coaxial cable harness 20 can be made small, and the height of the receiving portion can be made low so that The thickness can be reduced.

The small diameter coaxial cable harness 20 includes about 20 to about 60 small diameter coaxial cables 24. In the case where the small diameter coaxial cable 24 is about AWG46, when 40 small diameter coaxial cable harnesses 20 are formed as bundles of a cross-sectional shape close to a circle, the outer diameter (thickness) including the thickness of the braided sleeve 23 is formed. Is 1.7 mm or less, and it is possible to wire to the accommodating part of the height (thickness) of 1.7 mm.

The small diameter coaxial cable harness 20 is formed by tying a plurality of small diameter coaxial cables 24 through the braided sleeve 23 and covers the plurality of small diameter coaxial cables 24 by the braided sleeve 23. Thereby, durability of the small diameter coaxial cable harness 20 with respect to the friction at the time of sliding with wall surfaces, such as the board | substrates 11 and 12, improves. In addition, the small diameter coaxial cable harness 20 binds the loose and small diameter coaxial cable 24 by making the cross sectional area of the space inside the braided sleeve 23 larger than the sum of the cross sectional areas of the small diameter coaxial cable 24. . For this reason, when the casings 13 and 14 slide and the small diameter coaxial cable harness 20 deform | transforms, the small diameter coaxial cable 24 arranges in the braided sleeve 23, and is easy to move.

The braided sleeve 23 of this embodiment forms a tubular shape by braiding a polymer fiber. As the polymer fiber, it is preferable to use a monofilament hybrid fiber composed of a dissolved liquid crystalline polymer and a flexible polymer. This monofilament hybrid fiber is comprised by the core component which consists of a dissolved liquid crystalline polymer, and the exterior component containing a flexible polymer. Braided sleeves are flexible and wear resistant.

In one casing 13, a housing portion 30 in which the small diameter coaxial cable harness 20 can be accommodated is formed. This accommodating part 30 is provided with the wide lightening part 31 of the width | variety orthogonal to the slide direction of casings 13 and 14 comrades, and the narrow narrowing part 32 which is narrower than this lightening part 31. The width of the light portion 31 and the width narrow portion 32 is gradually changed by the position in the slide direction. As for the area | region from the light-expansion part 31 to the width narrow part 32, one side surface has curved surfaces 31a and 33a, and the curved surface 31a of the light-expansion part 31 is curved in convex shape to the outside, and the curved surface ( 33a) is curved in a convex shape inwardly. And in this casing 13, the big mounting space S which can mount an electronic component can be ensured in the side part of the width narrow part 32. As shown in FIG.

This accommodating part 30 is provided in the casing 13 by providing a groove | channel in the surface facing the casing 14. In addition, you may provide this accommodating part 30 by providing the guide wall in the facing surface with the casing 14 in the casing 13.

One end portion 21a of the small diameter coaxial cable harness 20 is fixed to the substrate 11 in the casing 13 provided with the accommodating portion 30, and the other end 21b of the small diameter coaxial cable harness 20 is fixed. It is fixed to the board | substrate 12 in the other casing 14. As shown in FIG. The small-diameter coaxial cable harness 20 has the other end portion 21b side through a hole portion (not shown) formed on an opposing surface of one casing 13 of the other casing 14.

Moreover, the accommodating part is located in the back surface (opposing surface of the casing 14) side of the casing 13 except the overlapping part which the casing 13, 14 overlaps with the casing 13, 14 open at least. The lid 34 which covers the 30 is provided, and the exposure of the accommodating part 30 is prevented by the state which opened the casing 13 and 14 by this. Moreover, the slit 35 through which the small-diameter coaxial cable harness 20 pulled out from the casing 14 side is inserted in this lid 34 is formed along the sliding direction of the casing 13,14. Since there is no lid 34, the housing part 30 may be exposed.

The small-diameter coaxial cable harness 20 is arranged on the side portion 30a side in which both ends 21a and 21b are formed in a linear shape of the receiving portion 30, and reciprocates twice in the width direction (M-shaped or Wire-shaped) so as to be W-shaped. As a result, in the state where the casings 13 and 14 are slid and opened, the small diameter coaxial cable 20 is formed on the light-expansion portion 31 on the curved surface 31a side in FIGS. 1 and 2A. Between the bent portions 41 and 43 and the bent portions 41 and 43, the bent portion 42 on the side part 30a side is accommodated in the shape of a wave formed.

The total length G of the accommodating part 30 is a state in which both ends 21a and 21b of the small diameter coaxial cable harness 20 are closest to each other by opening the casings 13 and 14 (state of FIG. 1). It becomes rather longer than the sum total of the space | interval L1 and the slide stroke L of these both ends 21a and 21b in Esau.

In addition, the width dimension W of the width narrow part 32 of the accommodating part 30 is the minimum of the small diameter coaxial cable harness 20 in the state which closed the casing 13 and 14 (state of FIG. 2). The width dimension is slightly wider than the diameter. As a result, the small diameter coaxial cable harness 20 is wired in a substantially linear shape in the width narrow portion 32. When the width of the narrow portion 32 is several times the diameter of the small diameter coaxial cable harness 20, the wave shape of the small diameter coaxial cable harness 20 is kept gently.

In addition, in the light-expansion part 31 of the accommodating part 30, the both ends 21a and 21b of the small diameter coaxial cable harness 20 come closest by opening the casings 13 and 14 (FIG. 1). (Circle), and it has a width dimension in which the small diameter coaxial cable harness 20 of a wave shape is accommodated enough.

The length of the small diameter coaxial cable harness 20 is equal to the distance L1 between the both ends 21a and 21b in a state where both ends 21a and 21b of the small diameter coaxial cable harness 20 are closest to each other (see FIG. 1). It is longer than the total of the slide stroke L and the shape of the wave shape is maintained somewhat even in the state in which the casings 13 and 14 are closed (the state of FIG. 2).

The small-diameter coaxial cable harness 20 is a state in which the casings 13 and 14 are opened and accommodated in a corrugated shape (the state in FIG. 1), and the height dimension of the peak having the bent portions 41 to 43 as a vertex is one end. It is long at the side of the (21a) side. Moreover, this small diameter coaxial cable harness 20 is preliminarily tended to be bent in a wave shape easily in the state in which the casings 13 and 14 are opened (state of FIG. 1).

In addition, one end portion 21a of the small diameter coaxial cable harness 20 may be disposed on the opposite side of the other end portion 21b and on the curved surface 31a side. In this case, the small diameter coaxial cable harness 20 has an even number of bending points.

Next, the movement of the small diameter coaxial cable harness 20 with expansion and contraction of the casings 13 and 14 is demonstrated.

When the casings 13 and 14 are gradually opened from the state in which the casings 13 and 14 are closed (the state of FIG. 2), as shown in FIG. 5A, the amount of the small diameter coaxial cable harness 20 is reduced. As the end portions 21a and 21b come closer, the radius of curvature of each of the bent portions 41 to 43 becomes smaller, and the respective bent portions 41 to 43 slide on the side surfaces of the receiving portion 30. In the state where the casings 13 and 14 shown in FIG. 2 are closed, the overlapping part of casings is the largest.

In addition, by opening the casings 13 and 14, as shown in FIG. 5B, when the bent portion 41 enters the light-expanded portion 31, the bent portions 42 and 43 are formed of the receiving portion 30. Under the reaction force from the side surface, the height of the mountain (distance in the width direction between the bent portion 42 and the bent portion 42) adjacent to the bent portion 41 is deformed so as to gradually increase.

Further, when the casings 13 and 14 are opened, the bent portion 43 also enters the light portion 31, and the small diameter coaxial cable harness 20 is accommodated in the light portion 31 in a state in which the corrugated cable harness 20 is folded in a wave form (Fig. 1). Reference).

At this time, since the small-diameter coaxial cable harness 20 folded in a wave form is disposed at an overlapping portion with the casings 13 and 14, for example, the lid 34 is provided on the rear surface of the casing 13. Even if it is a structure which the accommodating part 30 is exposed, the small diameter coaxial cable harness 20 is not exposed at the accommodating part 30 on the back side of the exposed casing 13, without providing.

When the casings 13 and 14 are gradually closed from the state in which the casings 13 and 14 are opened (the state of FIG. 1), as shown in FIG. 5C, the amount of the small diameter coaxial cable harness 20 is reduced. As the end portions 21a and 21b are separated, the bent portion 43 moves and slides in contact with the curved surface 33a which is a side surface of the accommodating portion 30. As a result, since the small-diameter coaxial cable harness 20 receives a reaction force directed toward the light-emitting part 31 side, the bent part 41 maintains the state as it is. In the state where the casings 13 and 14 shown in FIG. 1 are opened, the overlapping part of casings is the smallest.

When the casings 13 and 14 are closed, as shown in FIG. 5D, the bent portion 43 enters the width narrow portion 32 and the bent portion 42 is moved to each bent portion 41. The radius of curvature of ˜43) becomes large.

When the casings 13 and 14 are closed, as shown in FIG. 5E, the bent portions 42 and 43 enter the width narrow portion 32, and the bent portion 41 also moves to the bent portion 41. The height of the mountain peaked at) becomes low.

Then, when the casings 13 and 14 are completely closed, the small diameter coaxial cable harness 20 is stretched to have a gentle wave shape along the width narrow portion 32 (state of FIG. 2).

In this way, when the casings 13 and 14 are opened and closed, the small-diameter coaxial cable harness 20 is stretched in the direction of the slide smoothly in the receiving portion 30.

And according to the small diameter coaxial cable harness with a board | substrate which concerns on 1st Embodiment, the light-expansion part 31 which the small-diameter coaxial cable harness 20 can accommodate in a wave shape, and the width narrower than this light part 31 Since the accommodating part 30 which has the narrow part 32 was provided, the width dimension W of the width narrow part 32 can be made small. In the casings 13 and 14 in which the small diameter coaxial cable harness 20 is accommodated in such a receiving portion 30, the shape is U-shaped compared with the structure in which the small diameter coaxial cable harness 20 is accommodated in a U shape. When accommodated, the width dimension W of the width narrow part 32 is made into the small diameter coaxial cable harness, while the width dimension W of the width narrow part 32 is required more than the sum total of the diameter and the bending diameter of two small diameter coaxial cable harnesses 20. It can be suppressed by the width dimension slightly wider than the diameter of one of (20).

Thereby, the large mounting space S which an electronic component can mount can be ensured in the side part of the width narrow part 32 of the accommodating part 30, and the mobile telephone using this board | substrate small diameter coaxial cable harness ( In 10), the degree of freedom in designing the circuit board is increased, and further miniaturization of the casings 13 and 14 can be realized. On the other hand, smooth expansion and contraction of the small diameter coaxial cable harness 20 in the accommodating part 30 is possible, and the mechanical reliability of the small diameter coaxial wire is also high.

Moreover, in the small diameter coaxial cable harness with a board | substrate of the said structure, even if the endurance test which made the casing 13 and 14 reciprocate 200,000 times at 0.5 round trip speed per second did not generate an electrical disconnection.

In the above-mentioned small diameter coaxial cable harness with a board | substrate, although the case where the connector 25 was attached to the both ends 21a and 21b and subjected to star formation process was demonstrated, as shown in FIG. 6, the small diameter coaxial cable harness 20 of the board | substrate was demonstrated. It is also possible to attach the small diameter coaxial cable 24 directly to the board | substrates 11 and 12, and to perform a clustering process. In the case of directly attaching the small diameter coaxial cable 24 to the substrates 11 and 12, the terminal of the parallel small diameter coaxial cable 24 is temporarily fixed with a film or the like to the substrates 11 and 12, and the small diameter The center conductor of the terminal of the coaxial cable 24 may be connected to the connection terminals of the boards 11 and 12 by soldering.

The pitch is also fixed by connecting the ground bar 26 to the outer conductor, arranging the other ground bar 27 or the pressing member 27 from the opposite side, and sandwiching the small diameter coaxial cables 24. can do. It is also possible to attach directly to one side of the substrates 11 and 12 (see FIG. 6 (a)), and when attaching directly to the ends of the substrates 11 and 12, it may be attached directly to both sides (of FIG. 6). (b)). When the upper substrate 11 is connected to the lower substrate 12, the upper substrate 11 is attached to the lower substrate 12. It is not limited to attaching directly, but also when connecting to the board | substrates 11 and 12 with a connector etc. can be connected to both surfaces of the board | substrates 11 and 12. FIG.

In addition, the ends of the small diameter coaxial cable harness 20 may be replaced by a connector 25, for example, to a flexible substrate (FPC: Flexible Printed Circuits) having a wiring pattern such as metal foil, or a relay substrate such as a rigid substrate. It is also possible to connect and connect this relay board to the receptacle provided in the board | substrates 11 and 12. FIG. Moreover, the insulated wire which does not have an external conductor can be mixed suitably in the small diameter coaxial cable harness with a board | substrate of this invention as mentioned above. The insulated wire can be used as a ground wire, or the insulated wire can be used as a feed wire.

In addition, the small diameter coaxial cable harness with a board | substrate of this invention is not limited to said structure, A suitable deformation | transformation, improvement, etc. are possible.

As shown in FIG. 7, the shape of the light-expansion part 31 has the curved surface 31a which becomes wider once from the end toward the width narrow part 32 in the slide direction, and becomes narrow after that. In this case, the small-diameter coaxial cable harness 20 has a height (distance in the width direction between the bends) of the peak with the bends 41 to 43 in the state in which the casings 13 and 14 are opened. Is larger on the side of the other end 21b.

As shown in FIG. 8, the shape of the small diameter coaxial cable harness 20 is made into the waveform shape which has five bending parts 41-45. In this case, it is possible to lower the height of the mountain with each bent portion 41 to 45 as its apex, so that the width dimension can be reduced in the light-expanded portion 31 of the accommodating portion 30.

9, the straight part 21c along the slide direction is provided in the both ends 21a and 21b of the small diameter coaxial cable harness 20. As shown in FIG. In this case, it is easy to attach the small diameter coaxial cable harness 20 to the substrate.

In addition, in the above example, although the small diameter coaxial cable harness 20 which tied the some small diameter coaxial cable 24 over the full length by the braided sleeve 23 was used, as shown in FIG. ), A plurality of small diameter coaxial cables 24 may be bundled. In this case, the tape 28 binds the part except the both ends and the part which becomes the bent part 41-43 to be bent according to opening and closing of the casing 13,14. That is, the bending position can be specified by tying the small diameter coaxial cable 24 with the tape 28 except for the predetermined position.

In this way, the small-diameter coaxial cable harness 20 is smoothly bent at the bent portions 41 to 43 which become portions except the tape 28 as the casings 13 and 14 open and close. As a result, in the state in which the casings 13 and 14 are opened (the state of FIG. 10 (a)), the small diameter coaxial cable harness 20 is folded into a wave shape and accommodated in the light emitting portion 31, In the state where the casings 13 and 14 are closed (the state of FIG. 10 (b)), the small diameter coaxial cable harness 20 is extended in the accommodating part 30.

(Second Embodiment)

Next, the small diameter coaxial electric wire harness of 2nd Embodiment is demonstrated.

In addition, the same structural part as said 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits description.

As shown in FIG. 11, also in the case of 2nd Embodiment, each board | substrate 11 and 12 provided in the two casings 13 and 14 which move horizontally in the front-back direction (left-right direction of FIG. 11) arrange | positioned up and down respectively. Is connected by a small diameter coaxial cable harness 20 including a plurality of small diameter coaxial cables 24 (20 to 60). Both ends 21a and 21b of the small diameter coaxial cable harness 20 are connected in the vicinity of the center of the slide direction of the board | substrates 11 and 12, respectively.

Moreover, the accommodating part 30 is formed in the casing 13 (upper casing).

Example

The structure of the present invention (see FIG. 17) of the first embodiment, which folds and accommodates the small-diameter coaxial cable harness 20 in a shape of a wave in the light emitting portion 31, and the small-diameter coaxial cable harness 20 is curved in a U shape. The conventional structure (refer FIG. 18) to receive is compared. In all, the accommodation portion of the small diameter coaxial cable harness is located in the upper casing 13.

As a result, in the accommodating part 30 of the structure of this invention, the width dimension W1 of the width narrow part 32 which occupies many parts along the slide direction of the thing which requires the light-expansion part 31 is made into the rectangular length of the conventional structure. It can be made small compared with the width dimension W2 of the accommodation part 60.

Specifically, while the width dimension W2 of the accommodating part 60 of the conventional structure is 10 mm, the width dimension W1 of the width narrow part 32 of the accommodating part 30 of the structure of this invention was 5 mm.

This is because in the conventional structure, since the small-diameter coaxial cable harness 20 is always bent in the accommodation portion 60, the width dimension W2 of the accommodation portion 60 is smaller than the small-diameter coaxial cable harness 20. It is supposed to require a dimension equal to or larger than the sum of the diameters and the bending diameters of the two components. On the other hand, according to the structure of the present invention, since the small diameter coaxial cable harness 20 extends in the slide direction in the state where both ends 21a and 21b of the small diameter coaxial cable harness 20 are farthest from each other, This is because the width dimension W1 of 32 is suppressed to a width dimension slightly wider than the diameter of one small coaxial cable harness 20.

From this, according to the structure of this invention, it is possible to ensure the big mounting space S in the side part of the width narrow part 32 of the accommodating part 30, and, thereby, mounting the electronic component to this mounting space S. I knew this was possible.

In the case where the slide stroke is 60 mm, the accommodation portion of the present invention can have the following dimensions.

Overall length: 75 mm

Width of width narrow portion 32: 5 mm

Maximum width of the light emitting portion 31: 20 mm

Width narrow part 32 length: 37mm

The length of the width narrow part 32 is set to about ½ of the total length, and the light-expansion part 31 gradually widens from the width narrow part 32. In the case of a U-shaped wiring, the length of the housing portion can be 65 mm and the width can be 10 mm.

Comparing the area of the accommodating part in the above example, the case of the present invention is almost equivalent to 670 mm 2 and 650 mm 2 in the case of U-shape. If the stroke is shorter than 60 mm, the wiring of the present invention can reduce the area of the housing portion.

In the state where the casings 13 and 14 are opened, in the conventional structure, since the small diameter coaxial cable harness 20 exceeds in the accommodating part 60 which deviates from the overlapping portion of the casings 13 and 14, If the container 60 is not closed by the lid, the small diameter coaxial cable harness 20 will be exposed (see FIG. 18A).

On the other hand, in the structure of this invention, since the small diameter coaxial cable harness 20 folded in the wave shape is arrange | positioned in the overlapping part of casings 13 and 14, the small diameter coaxial does not need to close the accommodating part 30 with a lid | cover. The cable harness 20 is not exposed (see FIG. 17A).
