Description

  The present invention relates to a power feeding device that accommodates a wire harness bent in a case and expands and contracts the wire harness while moving a movable portion of the wire harness along the case.

  6A and 6B show an embodiment of a conventional power feeding device (see Patent Document 1).

  The power supply device 71 accommodates a flat wire harness 73 bent in a substantially U or J shape in a horizontally long case 72 made of synthetic resin, and a connector 74 on one end side of the flat wire harness 73 is connected to one end of the case 72. The connector 75 on the other end of the flat wire harness 73 is fixed upward on the slider 76, and the slider 76 is engaged with the rail portion of the case 72 so as to be slidable in the longitudinal direction.

  The power supply device 71 is applied to, for example, an automobile slide seat, the case 72 is disposed on the floor of the vehicle body, the fixed-side connector 74 is connected to the power-side wire harness, and the movable-side connector 75 is connected to the seat-side wire harness. Connected to. The seat-side wire harness is connected to an auxiliary machine such as an automatic slide motor, a reclining motor, or a seating sensor.

When the seat is advanced, for example, as shown in FIG. 6A, the movable connector 75 advances integrally with the seat, and the flat wire harness 73 is greatly shortened by wrapping left and right, and the seat is retracted. At this time, as shown in FIG. 6 (b), the movable connector 75 is retracted integrally with the seat, and the flat wire harness 73 is stretched with small wrapping to the left and right. The power feeding device 71 is not limited to a seat but can be applied to a sliding door of an automobile.
Japanese Patent Laid-Open No. 10-112922 (page 4, FIG. 12)

  However, in the above-described conventional power feeding device, the elasticity (restorability) of the electric wire itself is weak particularly when a wire harness made of a normal round electric wire is used instead of the flat wire harness 73. If the wire harness is bent or slacked irregularly, the wire harness will not expand or contract smoothly. As a result, there is a concern that abnormal noise and the like are likely to occur. Here, the wire harness refers to a state in which a plurality of electric wires are bound with a tape or the like, a state in which a plurality of electric wires are accommodated in a protective tube made of synthetic resin, and the like.

Further, as shown schematically in FIG. 7, when the wire harness 77 is fully extended as indicated by a solid line with the fixed-side connector 82 as a fulcrum, the folded portion 78 of the wire harness 77 is more than the movable-side connector 79. In order to project in a curved shape in the longitudinal direction of the case, it is necessary to set the entire length of the case 80 to a length obtained by adding the extra dimension L ₁ formed by the harness turn-back portion 78 to the slide stroke amount L of the connector 79. However, there was a problem of enlargement in the longitudinal direction.

  In view of the above, the present invention does not bend or loosen the wire harness irregularly (harmfully) in the case, thereby preventing damage or abnormal noise of the wire harness. And it aims at providing the electric power feeder which can make a case compact in a longitudinal direction.

  In order to achieve the above object, a power supply device according to claim 1 of the present invention is such that a portion on the fixed side of a wire harness is arranged at one side of a case in a middle portion in the longitudinal direction, along the other side of the case. The movable portion of the wire harness is movably disposed, and the wire harness portion on one end side introduced into the case from the fixed side portion faces the longitudinal direction of the case, and from the movable portion to the case The wire harness portion on the other end side introduced into the inside is arranged so as to face the lateral direction of the case.

  With the above configuration, as the movable part of the wire harness moves, the wire harness swings in the case with the fixed part as a fulcrum, and the wire harness part on the other end following the movable part is the case. It moves almost parallel to the longitudinal direction of the case while facing the short direction. The wire harness portion on the other end side is a wire harness portion in the vicinity of the movable portion. The remaining wire harness part following the wire harness part on the other end side is substantially J-shaped to substantially U-shaped in the case with the wire harness part on the other end side facing a substantially constant direction (case short direction). The film expands and contracts while being bent into a smooth substantially L shape. The wire harness is contracted in a substantially U-shaped form, and is stretched in a substantially J-shaped and substantially L-shaped form. Since the lead-out direction (case short direction) of the wire harness part on the other end side does not change with the movement of the movable part, the wire harness part on the other end side is harmful in the vicinity of the movable part. The wire harness shape changes from a substantially U-shape to a substantially L-shape with a strong J-shaped configuration that follows the wire harness portion on the other end side and exhibits a strong restoring force. Is restored elastically to prevent the occurrence of slack. This restoring force is also promoted by the fact that the wire harness part on one end side introduced from the fixed side part faces the case longitudinal direction. In addition, when the wire harness is bent in a substantially J shape, the fixed-side portion is arranged in the middle portion in the longitudinal direction of the case and the wire harness portion on the one-end side faces the longitudinal direction of the case. Since the bent portion (folded portion) following the wire harness portion faces not the outside of the case but the inside, the space in the case is effectively utilized. Examples of the movable portion include a movable connector, a slider fixed to the outer periphery of the wire harness portion (wire bundle or protective tube), and the wire harness portion itself. Examples of the fixed portion include a fixed connector, a fixing member that fixes the wire harness portion, and the like.

  The power supply device according to claim 2 is the power supply device according to claim 1, wherein the wire harness portion on the other end side is followed by a small-diameter bent portion at the start end position of the movable portion, and the bent portion is a straight portion. Followed by the wire harness portion on the one end side through the bent portion in the opposite direction, and at the terminal position of the movable portion, the wire harness portion on the other end side has a large diameter opposite to the small-diameter bent portion. It is characterized by continuing to the wire harness portion on the one end side through a bent portion.

  With the above configuration, the wire harness exerts a strong restoring force at the small-diameter bent portion and the reverse-direction bent portion as the movable portion moves from the start end to the end, and from a substantially J shape to a smooth L Restore the shape of the letter. In addition, when the wire harness is bent from a substantially L shape to a substantially J shape as the movable part moves from the end to the start end, the wire harness has a strong elastic force (restoring force) and has a pin. The tensioned state prevents harmful loosening of the wire harness and harmful small-diameter bends.

  A power supply device according to a third aspect is the power supply device according to the first or second aspect, wherein the wire harness has a corrugated tube on an outer periphery.

  With the above configuration, the corrugated tube made of synthetic resin imparts a strong elastic force (restoring force) to the wire harness as well as bendability, and the wire harness has an approximately J-shaped configuration with a small-diameter bend or an approximately L Reliably prevents slack in the letter-like form. The corrugated tube is an existing one in which circumferential grooves and ridges are alternately arranged in the tube longitudinal direction.

  According to the first aspect of the present invention, the wire harness fixed portion of the wire harness is disposed in an intermediate portion with respect to the movable range of the movable portion, and each wire harness portion continues to the fixed portion and the movable portion. Is derived in the direction orthogonal to the inside of the case, giving a strong restoring force to the wire harness in the case, thereby preventing the wire harness from loosening and preventing vibration, noise, wear, etc. due to the loosening. In addition, harmful bending such as bending of the wire harness is prevented, damage to the wire harness caused by bending and deterioration of bending durability are prevented, and the reliability of power supply is improved. By turning the folded part of the harness toward the inside instead of facing the outside as in the past, the case is made compact in the longitudinal direction, and the mounting space of the vehicle or the like on which the power feeding device is mounted is reduced. That.

  According to the invention described in claim 2, since the wire harness bends in a state having a strong elastic force as the movable portion moves forward and backward, the wire harness is prevented from being loosened or bent, and the vibration caused by them is prevented. , Noise, wear and bending durability are reliably prevented. In addition, since the reverse bent portion of the wire harness faces the inside rather than the outside of the case, downsizing of the case in the longitudinal direction is reliably achieved.

  According to the invention of claim 3, the corrugated tube imparts a strong elastic force (restoring force) to the wire harness, so that the wire harness can be more reliably prevented from being bent or bent, and the wire harness can be The prevention of abnormal noise and the like and the improvement of bending durability are promoted, and the reliability of power feeding is further improved.

  1 to 3 show an embodiment of a power feeding device according to the present invention.

  As shown in FIG. 1 (schematic diagram), the power feeding device 1 includes a connector 3 (fixed side portion) on the fixed side of the wire harness 6 and a case 2 on the middle in the longitudinal direction on one side of the synthetic resin case 2. A movable connector 5 (movable portion) of the wire harness 6 is provided along the long side portion 23 on the other side, and the movable connector 5 is located between one end and the other end of the case 2 in the longitudinal direction. The wire harness 6 is bent and swung in the case using the fixed connector as a fulcrum.

  The fixed-side connector 3 faces the longitudinal direction of the case 2 in the middle part of the sliding area of the movable-side connector 5, and the fixed-side connector 5 faces the short side direction (width direction) of the case 2. The wire harness portion 43 led out from the connector 5 is directed in the longitudinal direction of the case 2, and the wire harness portion 44 led out from the movable connector 5 is oriented in the short direction of the case 2.

  In FIG. 2, reference numeral 12 denotes an upper case, 13 denotes a lower case, and 6 denotes a wire harness. The upper and lower cases 12 and 13 are made of a synthetic resin material, and in a joined state, the upper and lower cases 12 and 13 are fixed to each other by a locking means (not shown) such as a locking projection and a locking frame piece, or a means such as adhesion or welding. One case (protector) 2 (FIG. 3) is comprised. The wire harness 6 is configured by covering a plurality of round covered electric wires with a corrugated tube 15 which is a protective tube made of synthetic resin, and arranging connectors 3 and 5 at both ends of the electric wire 14, respectively.

  Each connector 3, 5 is composed of a synthetic resin connector housing (represented by reference numerals 3, 5) and a terminal (not shown) accommodated in the connector housing, and the terminal is connected to the electric wire 14 by means such as crimping. It is connected. In this example, each of the connectors 3 and 5 has a terminal accommodating chamber for accommodating a female terminal, followed by a mating terminal insertion port 16. The connector 3 on the fixed side and the connector 5 on the movable side face the direction in which the connection surfaces 17 are orthogonal to each other. It is also possible to accommodate the male terminals in both the connectors 3 and 5 or any one of the connectors and to have a connector fitting chamber for the mating connector.

  The corrugated tube 15 is an existing tube in which circumferential annular grooves 20 and ridges 21 are alternately arranged in the tube longitudinal direction to add flexibility and elasticity (restorability). The corrugated tube 15 is formed in a cross-sectional flat shape or an oval shape in order to improve the flexibility of the case in the longitudinal direction and the short direction. It is preferable that one end portion of the corrugated tube 15 is fixed to the movable connector 5 or a portion of the lead-out electric wire from the movable connector 5 by means such as fitting, tape winding or band binding. The same applies to the other end of the corrugated tube 15 and the connector 3 on the fixed side.

  A corrugated tube (not shown) having a circular cross section can be used instead of the corrugated tube 15 having an elliptical cross section. Further, as the protective tube, a flexible tube such as urethane, a vinyl tube, a braided tube, or the like (not shown) can be used instead of the corrugated tube 15.

  An opening 24 is provided in the vertical wall portion 23 on the long side of the upper and lower cases 12 and 13, and a flange portion 28 is formed on the entire periphery of the opening portion 24. The groove 29 on the outer periphery of the connector 5 on the side is slidably engaged. The flange portion 28 acts as a rail portion, and the groove portion 29 acts as a guide portion.

  As shown in FIG. 2, the lower case 13 is formed deeper than the upper case 12 (the dimension in the vertical direction is larger). After the wire harness 6 is assembled in the lower case, the upper case 12 is covered. The upper and lower cases 12, 13 are composed of one narrow portion 30 and the other wide portion 31 in the longitudinal direction, and are orthogonal to the wall portion 32 facing the opening 24 of the narrow portion 30. An opening 34 for fixing the connector is provided at 33, and a groove 36 on the outer periphery of the connector 3 on the fixed side engages with the flange 35 around the opening 34. In the assembled state of FIG. 3, the connection surface 17 of the fixed-side connector 3 faces the longitudinal direction of the case 2, the connection surface 17 of the movable-side connector 5 faces the short direction of the case 2, The direction is orthogonal.

  Note that the directions such as “up and down” in the specification are those when the power feeding device 1 is horizontally placed horizontally. For example, when the power feeding device 1 is vertically placed vertically, “up and down” is “right and left”. Or “before and after”.

  In FIG. 2, when the wire harness 6 is assembled in the lower case, the movable connector 5 is slidably engaged with the flange portion 28 of the opening 24, and the front half of the connector protrudes outside from the opening 24 and is fixed. The side connector 3 is fixed to the other opening 34. In this state, the upper case 12 is attached, the wire harness 6 is accommodated in the upper and lower cases in a bent state, and the groove portions 29 and 36 of both the connectors 3 and 5 are formed in the flange portions 28 and 35 of the upper case 12. Engage with each other.

  As shown in FIG. 1, the wire harness portion 44 led out from the movable connector 5 in the case 2 is located in the narrow portion 30 on the left end side of the case 2, and the narrow portion 30 and the extension thereof are arranged in the longitudinal direction of the case. It moves in a direction that is substantially straight in the direction (in a form that is substantially straight in the short direction of case 1). The wire harness portions 39, 38, (42) following the wire harness portion 44 on the movable connector side are positioned straight in the longitudinal direction of the case within the narrow portion 30 of the case, or bent in an arc shape or a curved shape within the wide portion. Located.

  As shown in FIG. 3, the movable connector 5 is linearly slidable along the elongated opening 24 of the case 2 in the assembled state of the power feeding device 1, and the sliding operation of the movable connector 5 is performed. As shown in FIG. 1, the wire harness 6 expands and contracts in the case while being bent from a substantially J shape like a solid line to a smooth substantially L shape like a chain line.

  The substantially J shape refers to a portion 38 that is folded back from the fixed connector 3 in a substantially semicircular shape within the wide portion 31 of the case 2, and a narrow portion 30 of the case 2 following the folded portion (bent portion) 38. A straight portion 39 extending substantially parallel to the longitudinal direction of the case, and a bent portion 11 bent in an arc shape in a 90 ° direction from the straight portion 39 toward the movable connector 5 in the narrow portion 30. The two bent portions 11 and 38 are bent in opposite directions. The ¼ arc-shaped bent portion 11 includes a wire harness portion 44 in the vicinity of the movable connector 5.

  Further, the substantially L shape means that a straight portion 41 extending in parallel along the vertical wall portion 40 (FIG. 2) of the case 2 from the fixed connector 3 in the wide portion 31 of the case 2 and the straight portion 41. It is composed of a large-diameter bent portion 42 bent in an arc shape in the 90 ° direction toward the movable connector 5, and has only one bent portion 42. The bent portion 42 includes a wire harness portion 44 in the vicinity of the movable connector 5.

  The movable connector 5 is slidably engaged along the flange portion 28 of the opening 24 of the case 2 as shown in FIG. 3, and the wire harness portion 44 following the movable connector 5 is completely slid as shown in FIG. In the region, the space on the side of the opening 24 of the case 2 crosses in the lateral direction of the case, and most of the wire harness portions (portions 39, 38 or portions 42, 41) following the wire harness portion 44 are approximately corresponding to the slide region. It is folded back into a J-shape, U-shape or L-shape and continues to the connector 3 on the fixed side. The substantially J-shaped bend of the wire harness 6 is at the left end (starting end) position of the movable-side connector 5, the substantially U-shaped bend is at the middle position of the connector 5, and the substantially L-shaped bend is the connector. 5 at the right end (end) position. “Starting end” and the like are for convenience of explanation, and do not particularly indicate the initial position of the movable connector 5.

  When the wire harness 6 is bent into a substantially J-shape as shown by the solid line in FIG. 1, the straight portion 39 of the wire harness 6 is positioned substantially straight along the wall portion 32 (FIG. 2) of the narrow portion 30 of the case 2. The bent portion 11 following the portion 39 is bent with a relatively large radius, and damage of each electric wire of the wire harness 6 in the bent portion 11 is prevented. This function and effect is particularly prominent when the corrugated tube 15 (FIG. 2) is attached to the outer periphery of the wire harness 6. That is, since the wire harness 6 has high resilience, the straight portion 39 of the wire harness 6 is positioned straight without slack, and the bent portion 11 following the straight portion 39 is bent with a relatively large radius.

  Moreover, since the lead-out direction (case short direction) of the wire harness portion 44 on the movable connector side does not change with the movement of the movable connector 5, the wire harness portion 44 is harmful in the vicinity of the movable connector 5 ( There is no bending (such as bending to a small diameter), and the substantially J-shaped form portions 11, 39, 38 following the wire harness portion 44 exhibit a strong restoring force, so that the substantially U-shaped to the substantially L-shaped. The wire harness shape is elastically restored to prevent the occurrence of slack.

  Further, when the wire harness 6 bends from a substantially J shape to a substantially L shape such as a chain line as the movable connector 5 moves, the wire harness 6 is moved in the direction of arrow A (in the wide portion 31 of the case 2). A restoring force (toward the wall 40 opposite to the opening 24) acts, and the wire harness 6 bends in a substantially L shape without harmful slack. This effect is due to the wire harness portion 43 following the connector 3 on the fixed side being led out in the case longitudinal direction. This function and effect is particularly prominent when the corrugated tube 15 (FIG. 2) is attached to the outer periphery of the wire harness 6.

  For example, as shown in FIG. 4A, when the fixed-side connector 46 is arranged not in the longitudinal direction of the case but in the lateral direction of the case in the middle portion in the longitudinal direction of the case 45, the movable connector 47 slides. In operation, the wire harness 48 swings around the fixed connector 46 as a fulcrum, and when the movable connector 47 comes to a position opposite to the fixed connector 46 as shown in FIG. Since the direction intermediate portion 49 is bent so as to be bent to a small diameter in the case, and the wire harness portion 50 led out in the vicinity of both the connectors 46 and 47 is bent to a small diameter, the bending durability of the wire harness 48 is lowered. At the same time, the smooth operation of the wire harness 48 is not performed, and the slide operability of the movable connector 47 is deteriorated.

  On the other hand, by arranging the connector 3 on the fixed side in the longitudinal direction of the case as shown in FIG. 1, these problems are solved, and the wire harness 6 bends smoothly with a large radius. The bending durability is improved, and the expansion / contraction operation of the wire harness 6 and the sliding operation of the movable connector 5 are performed smoothly.

  Further, since the movable connector 5 is not directed in the longitudinal direction of the case 2 as in the conventional example (FIG. 6), but is directed in the short direction of the case 2, the connector of the counterpart wire harness (not shown). Can be directly and smoothly connected to the movable connector 5 from the direction orthogonal to the sliding direction of the movable connector 5 without bending the counterpart wire harness. Bending fatigue and the like are prevented.

  The power feeding device 1 in which the movable connector 5 is directed in the short direction of the case 2 is suitable for feeding power to a slide structure (not shown) such as a slide seat or a slide door of an automobile. When the power feeding device 1 is applied to a slide seat, for example, the case 2 is disposed on the floor of the vehicle body with the opening 24 facing upward, and the wire harness on the seat side is connected to the movable connector 5 almost straight from above. Therefore, there is no worry that the wire harness on the seat side is bent to a small diameter in the vicinity of the connector 5. A wire harness (not shown) on the vehicle body (power source) side is connected to the connector 3 on the fixed side.

  Further, when the power feeding device 1 is applied to a slide door, for example, the case 2 is disposed horizontally on the vehicle body with the opening 24 facing sideways (toward the slide door), and the wire harness on the slide door side is almost from the side. Since the straight connector is smoothly connected to the movable connector 5 straight, there is no fear that the wire harness on the slide door side bends to a small diameter in the vicinity of the connector 5. A wire harness on the vehicle body (power source) side is connected to the connector 3 on the fixed side.

  When the power feeding device 1 is arranged perpendicular to the sliding door, the position of the connection surface 17 of the movable connector 5 in FIG. 3 is formed on the upper case 12 side, and terminals (not shown) in the movable connector are formed. Can be bent in an L shape, and the opening 24 of the case 2 can be disposed downward, so that the wire harness on the vehicle body (power source) side can be connected to the connector 5 on the movable side almost straight from the side. In this case, the wire harness on the slide door side is connected to the connector 3 on the fixed side. The application part of the power supply apparatus 1 can be applied to various slide mechanisms besides these.

  In these application examples of the power supply device 1, by using the highly recoverable wire harness 6 having the corrugated tube 15, the wire harness portions 11, 39, 41, and 42 following the movable connector 5 are slackened or bent to a small diameter. The wire harness portions 39, 41, and 42 are prevented from vibrating, abnormal noise, wear and the like, and the bending stress applied to the wire harness portion 11 is suppressed to a small level. In this case, the wire harness 6 is smoothly expanded and contracted without being caught in the case, thereby improving the slide operability.

  Further, compared to the conventional example (FIG. 6), the semicircular folded portion 38 of the wire harness 6 faces inward without facing the outer side of the case 2, so that the space 37 in the case 2 is effectively utilized, The enlargement of the case 2 in the longitudinal direction due to the bending radius of the folded portion 38 is prevented, and the case 2 is made compact in the longitudinal direction.

  In the above embodiment, the connection surface 16 at the tip of the fixed connector 3 is directed in the case longitudinal direction and the connection surface 17 at the tip of the movable connector 5 is directed in the case short direction. A terminal (not shown) bent in a substantially L shape is provided inside, an electric wire is connected to the base side of the L-shaped terminal, and a terminal of the mating connector is connected to the distal end side of the terminal, It is also possible to arrange the connection surfaces 17 of the connectors 3 and 5 in a direction orthogonal to the connection surface 17. In short, the direction of the wire harness portions 43 and 44 led out from the connectors 3 and 5 needs to face the case longitudinal direction in the fixed connector 3 and the case short direction in the movable connector 5. The direction of the connection surface 17 of the connectors 3 and 5 may not necessarily coincide with the direction in which the wire harness portions 43 and 44 are led out.

  In the above-described embodiment, the movable connector 5 is directly slidably engaged with the opening 24 of the case 2. For example, as in the power supply device 1 ′ in the embodiment of FIG. A slider 52 made of synthetic resin, which is a movable portion, is slidably engaged with the opening 24 of the case 2, and a wire harness portion 54 is led out of the case 2 from the slider 52. It is also possible to dispose the movable-side connector 5 on the slider 52, or to provide the slider 52 with the movable-side connector 5 integrally or separately.

  In the embodiment of FIG. 5, the slider 52 is fixed to the outer periphery of the corrugated tube 15 (FIG. 2) of the wire harness 6. As an example, the slider 52 is formed in a divided manner, and an arc-shaped rib is provided on the inner peripheral surface of the slider 52, the rib engages with the concave groove of the corrugated tube 15, and the slider 52 has a rectangular outer peripheral surface. A groove portion is provided, and the groove portion is slidably engaged with the upper and lower flange walls 28 (FIG. 2) of the elongated opening 24 (FIG. 2) of the case 2. When the corrugated tube 15 is not used, the slider 52 is fixed by sandwiching the outer peripheral surface of the protective tube such as the outer peripheral surface of the wire bundle or the mesh tube. The shape of the slider 52 is not limited to a rectangular cylindrical shape, and is appropriately set as necessary. The same applies to the movable connector 5 of the above embodiment.

  When the slider 52 is not used, for example, the concave groove of the corrugated tube 15 (FIG. 2) is slidably engaged with the flange wall 28 of the opening 24 (FIG. 2), or the wire harness 6 in the case is opened. A hook-shaped member (slider not shown) is provided on the outer peripheral surface of the wire harness 6 so as not to protrude from the portion 24 to the outside, and the hook-shaped member is brought into contact with the inner surface of the wall 28 of the opening 24 (sliding contact). It is preferable to let them. The distance between the movable-side connector 5 and the opening 24 is short, and the movable-side connector 5 moves in parallel along the opening 24 together with a mating connector (not shown) such as a slide door or slide seat. In this case, there is no fear that the wire harness 6 jumps out of the opening 24 without providing the slider 52. In this case, the wire harness itself in the opening becomes the movable portion.

  In the embodiment of FIG. 5, the fixed-side wire harness portion 51 (fixed-side portion) 51 is not the fixed-side connector 3 as a fixed-side portion of the wire harness 6 but is fixed by a case 2 such as a band, tape winding, or clamp. Is fixed to the narrow opening 34 (FIG. 2). The wire harness portion 53 from the opening 34 to the fixed connector 3 can be appropriately bent according to the position of a mating connector (not shown) such as a vehicle body.

  In FIG. 5, the other parts excluding the fixed-side part 51 and the movable-side part 52 are the same as those in the embodiment of FIG. 1. In FIG. 5, the fixed connector 3 is used as the fixed portion, the slider 52 is used as the movable portion, the wire harness 51 is used as the fixed portion, and the movable connector 5 is used as the movable portion. It is also possible.
