  However, in the conventional electrical connection structure described above, the wire harness is always urged upward by the leaf spring in the power supply harness protector. For this reason, the outer shape of the power supply harness protector is increased, and, for example, the placement space of the electrical component on the sliding door side is pressed, and there is a problem that the degree of freedom in designing the layout of the electrical component is limited.

  Further, in the above-described conventional electrical connection structure, the harness fixing portion is attached to the vehicle body in a state that it can swing in the longitudinal direction of the vehicle, for example, with the fixing shaft of the bracket as a fulcrum. Therefore, there is a problem in that the number of parts increases, and various costs such as manufacturing costs and assembly costs increase.

  Furthermore, in the above-described conventional electrical connection structure, since the wire harness is simply led out from the opening and mouth of the power supply harness protector toward the harness fixing portion, these openings are provided inside the power supply harness protector. There is a problem that foreign matter or the like may enter through the part or the mouth part, and the wire harness may be damaged or the movement of the wire harness may be significantly affected.

  In the conventional electrical connection structure described above, the protector body and the protector cover of the power supply harness protector are made of synthetic resin, so that the protector itself bends due to environmental changes such as temperature changes and humidity changes, resulting in significant dimensional errors. There is a problem that there is a risk of hindering the movement of the elastic member that biases the wire harness.

  The present invention has been made in view of the above points, and is intended to reduce the cost while improving the degree of freedom in layout design, to reliably support the movement of the wire harness, and to be less affected by environmental changes and smoothly. An object is to provide an electric connection structure that can be moved.

A metal rail that restricts the movement of the slider by being inserted in the concave groove while pressing the buffer portion while pressing the buffer portion; and And a box-shaped protector which is arranged on the moving side member and extends along the parallel direction.

  By configuring the electrical connection structure according to the present invention as described above, the tip of the metal rail provided in the second storage chamber of the protector is interposed in the concave groove while pressing the buffer portion of the support portion of the slider. In order to realize a structure that regulates the movement of the slider, the cost of the layout design is improved while the flexibility of layout design is improved, and the movement of the wire harness is surely supported and is not easily affected by environmental changes. It becomes possible to move to.

  The concave grooves are respectively formed on both side surfaces of the support portion, and buffer portions are provided respectively. The metal rail is formed in a C-shaped cross section having an opening above, and forms a C-shape. Each of the pair of tips may be configured to restrict the movement of the slider by being interposed in the concave groove while pressing the buffer portion.

  Further, the biasing means is a tension member in which one end is fixed to the inner wall surface of the protector in the second accommodating chamber in the sliding movement direction, and the other end is fixed to the outer peripheral surface of the support portion of the slider disposed opposite to the inner wall surface. You may be comprised by the spring part. Further, the buffer portion of the slider may be made of a felt material.

  Further, the protector may be configured to include a housing main body portion in which the second storage chamber is formed and a housing cover portion in which an isolation portion detachable from the housing main body portion is formed. . Here, the wire harness may have a structure in which a plurality of electric wires are bundled and covered with a protective member. The protective member may be made of a corrugated material. The fixed member may be a vehicle body, and the moving member may be a slide door attached to the vehicle body.

  According to the present invention, the intermediate portion of the bendable wire harness that electrically connects the stationary member and the movable member is biased by the biasing means to guide the wire harness in the sliding movement direction of the movable member. Along with the urged slider, it is accommodated in a box-shaped protector that is disposed on the stationary member or the movable member and extends along the sliding direction. For this reason, the outer shape of the protector can be reduced, and the degree of freedom in designing the layout of the electrical components can be improved.

  Further, according to the present invention, there is no need to provide a so-called swing mechanism as in the prior art at both ends of the wire harness fixed to the fixed side member and the movable side member, respectively, and a component for realizing an electrical connection structure Costs can be reduced by reducing the number of stores. Further, according to the present invention, the intermediate portion of the wire harness and the harness contact portion of the slider are isolated in the first storage chamber by the isolation portion with respect to the second storage chamber of the protector in which the support portion of the slider is stored. For this reason, even if foreign matter or the like is mixed into the first storage chamber from the opening of the protector, further mixing into the second storage chamber can be effectively prevented, and malfunction of the slider can be prevented, and the wire harness can be prevented. It can be moved smoothly.

  In addition, according to the present invention, the tip of the metal rail provided in the second storage chamber is interposed in the plurality of concave grooves in the slider support portion in a state of pressing the buffer portion, so that the movement of the slider is prevented. While realizing a structure that is not easily affected by an environmental change that prevents the slider, the slider can be reliably moved while suppressing rattling during the movement of the slider in the protector.

FIG. 13 to FIG. 15 are operation explanatory diagrams in a state where the electrical connection structure is simply viewed from the vehicle interior side.

  As shown in FIG. 1, a power feeding device 1 that realizes an electrical connection structure according to this embodiment includes a vehicle body 2 (see FIGS. 7 to 9, the same applies hereinafter) as a stationary member, and the vehicle body 2. The sliding door 3 (see FIGS. 6 to 9; the same applies hereinafter) as a moving member that can slide in the direction of the arrow PA in FIGS. 7 to 15 (hereinafter referred to as “PA direction”). They are electrically connected. In this example, the power supply circuit of the power feeding device 1 is omitted and described, and the slide door 3 is attached to the left side of the vehicle body 2.

  The power supply device 1 includes a wire harness 6, a slider 10 that guides the wire harness 6, and a protector 20 that houses the slider 10. For example, one end of the wire harness 6 is fixed to the vehicle body 2 via a harness fixing portion 4 (see FIGS. 6 to 9 and 13 to 15, the same applies hereinafter) and a connector 5 (see FIGS. 7 to 9, the same applies hereinafter). Is done. Further, the wire harness 6 is disposed on the vehicle body 2 and the slide door 3 with the other end fixed to the slide door 3 and a middle portion between both ends bendable.

  Specifically, the wire harness 6 is fixed by the harness fixing portion 4 with one end connected to a wiring (not shown) on the vehicle body 2 side via the connector 5. The other end is connected and fixed to each electrical component (not shown) such as a power window device on the slide door 3 side via a connector (not shown). Thus, in the electrical connection structure of the present example, each fixed end of the wire harness 6 does not need to be swingably fixed by a so-called swing mechanism as in the prior art.

  The wire harness 6 has a structure in which, for example, a plurality of electric wires are bundled and the outer peripheral portion thereof is covered with a protective member made of a corrugated material, and is configured to have appropriate flexibility and elasticity so that it can be bent. . Here, the PA direction refers to the front-rear direction of the vehicle body 2, and hereinafter, “front-rear” refers to a direction that coincides with the front-rear direction of the vehicle body 2 unless otherwise specified.

  The slider 10 moves in a relative direction (hereinafter referred to as “parallel direction”) parallel to the PA direction in conjunction with the sliding movement direction of the sliding door 3 while contacting the intermediate portion of the wire harness 6, and moves the wire harness 6 back and forth. Guide in the direction. The slider 10 is made of, for example, a resin molded member. As shown in FIGS. 1 to 4, the slider 10 includes a harness contact portion 12, a support portion 13 that supports the harness contact portion 12, and a connecting portion 14 that connects them. It is prepared for. The harness contact portion 12 includes, as one of the parallel directions, a curved portion 11 having a curved surface that is bent with a radius of curvature larger than the minimum radius of curvature of the wire harness 6 so as to protrude, for example, in the rearward direction. ing.

  The support portion 13 supports the harness contact portion 12 in a state movable in the parallel direction with respect to the protector 20, and is formed (extended) along the parallel direction with an opening in a direction orthogonal to the parallel direction, for example. And a plurality of holes 13c to 13f formed so as to communicate with the recesses 13a and 13b from the outer peripheral surface. A buffer portion 13g made of, for example, a felt material is inserted into each of the plurality of hole portions 13c to 13f of the support portion 13 so as to block a part of the recess portions 13a and 13b (near both ends in the parallel direction). . The pair of recesses 13a and 13b of the support portion 13 are engaged with the metal rail described later in a state where the buffer portion 13g is in sliding contact.

  The connecting portion 14 has a shape bent so as to have a crank-shaped cross section, and connects the harness contact portion 12 and the support portion 13. Due to such a structure of the slider 10, when the power feeding device 1 that realizes the electrical connection structure of this example is actually used, the intermediate portion of the wire harness 6 is a connecting portion 14 between the harness contact portion 12 and the support portion 13. It is arranged so as to always pass through the concave part. And the intermediate part of the wire harness 6 will be in the state bent along the curved surface of the curved part 11 of the harness contact part 12, when it is the most bent state.

  For example, the protector 20 is disposed in the slide door 3 and is formed in a box shape whose longitudinal direction extends along the front-rear direction. This protector 20 is made of a resin-molded member like the slider 10, and as shown in FIGS. 1, 4, and 5, a first housing that houses the harness contact portion 12 of the slider 10 and the intermediate portion of the wire harness 6. A separating portion 22 that partitions the housing space 29 that is a chamber and the housing chamber 21 that is the second housing chamber that houses the support portion 13 of the slider 10, an opening 23 for leading the wire harness 6 to the outside, and the housing chamber 21. A metal rail 28 that engages the recesses 13a and 13b of the support portion 13 of the slider 10 so as to be in sliding contact with the buffer portion 13g, and a tension spring portion 27 that is an urging means for urging the slider 10, respectively. It is configured with.

  Further, the protector 20 includes, for example, a housing main body portion 20a in which a storage chamber 21 is formed, and a housing cover portion 20b that is detachable from the housing main body portion 20a and in which an isolation portion 22 is formed. It is formed so that it can be divided. By providing a structure that can be divided in this manner, the power supply device 1 can improve the accessibility to the protector 20 during maintenance of the wire harness 6 and the slider 10, for example. Moreover, by providing the isolation | separation part 22, the storage chamber 21 and the storage space 29 can be divided spatially reliably.

  Here, the accommodating space 29 accommodates the intermediate portion of the wire harness 6 together with the harness contact portion 12 of the slider 10 so as to be movable in the parallel direction, and the accommodating chamber 21 has, for example, a metal having a C-shaped cross-sectional shape. A rail 28 made of screws is directly screwed and accommodated in the accommodation chamber 21 using screws or the like (not shown), and a pair of recesses 13a of the support portion 13 of the slider 10 is sandwiched between opposing ends of the rail 28 with a slit therebetween. , 13b, and the support portion 13 is slidably engaged and accommodated in the parallel direction.

  In addition, the rail 28 should just be formed with the cross-sectional shape in which the opposing edge part engaged with recessed part 13a, 13b is formed other than a C-shaped cross section. The rail 28 is made of a metal member such as aluminum (Al), iron (Fe), and stainless steel (SUS). The isolation part 22 (see FIG. 5, the same applies hereinafter) extends in the longitudinal direction of the protector 20, for example, and extends in a direction connecting the casing body 20a and the casing cover 20b (hereinafter referred to as “horizontal direction”). It consists of partition plates, such as a protruding protrusion.

  The opening 23 is formed on the opposite side of the isolation portion 22 from the side where the accommodation chamber 21 is formed in order to reliably lead out the wire harness 6 from the accommodation space 29 to the outside. The opening 23 is formed, for example, by continuously opening a part of the rear side wall and the lower side wall of the protector 20. A lead-out hole 24 for leading the wire harness 6 to the fixed side of the slide door 3 is formed in a part of the front side wall portion of the protector 20.

  One end of the tension spring portion 27 is fixed to the rear inner wall surface in the parallel direction of the storage chamber 21 of the protector 20, and the other end is fixed to the outer peripheral surface of the support portion 13 of the slider 10 disposed to face the inner wall surface. Thus, for example, the slider 10 is urged so as to be pulled by the restoring force to the side where the bending portion 11 protrudes.

  For example, when the distance in the parallel direction with respect to the rear inner wall surface of the storage chamber 21 of the slider 10 is more than a predetermined amount, the tension spring portion 27 is loaded with respect to the movement amount of the slider 10 (that is, the rear inner wall surface side). It is desirable to have a so-called constant load characteristic such that the tensile force is substantially constant.

  Since the tension spring portion 27 has a load characteristic of a constant load, the slider 10 can move smoothly in the protector 20. For this reason, the wire harness 6 can be reliably guided according to the movement of the slide door 3.

  In the power supply device 1 including the electrical connection structure configured as described above, a structure is realized in which the intermediate portion of the wire harness 6 is accommodated in the box-shaped protector 20 that extends along the longitudinal direction in the front-rear direction together with the slider 10. . In addition, a structure in which the tension spring portion 27 that biases the slider 10 is accommodated in the accommodation chamber 21 of the protector 20 is realized. For this reason, the external shape of the protector 20 can be made small.

  Therefore, for example, as shown in FIG. 6, when the power feeding device 1 is disposed on the slide door 3 side, it is possible to secure a wide space for disposing various electrical components. As a result, the degree of freedom in layout design can be improved. In this case, the so-called surplus length, which is an extra length of the wire harness 6, is linked to the smooth operation from the maximum movement to the minimum movement of the slider 10 in the protector 20 realized by the tension spring portion 27. It is absorbed in the 20 accommodating spaces 29.

  According to the power supply device 1 configured as described above, when the slide door 3 is in the fully open position with respect to the vehicle body 2 in the rearward direction in the front-rear direction, as shown in FIGS. The wire harness 6 is in the following state. That is, the intermediate portion of the wire harness 6 in the accommodating space 29 is bent in a state where a substantially constant tension is applied by the tension spring portion 27 while being in contact with the harness contact portion 12 and the connecting portion 14 of the slider 10. However, the bending portion 11 will not bend more than the minimum curvature. For this reason, extra stress such as unreasonable tension or compression is not applied to the intermediate portion of the wire harness 6.

  As shown in FIGS. 8, 11, and 14, when the sliding door 3 is slid halfway in the front-rear direction from the fully open position toward the fully closed position, the wire harness 6 is as follows. It becomes a state. That is, the intermediate portion of the wire harness 6 in the accommodating space 29 is bent in a state where a substantially constant tension is applied by the tension spring portion 27 while being in contact with the harness contact portion 12 and the connecting portion 14 of the slider 10 as described above. . However, as described above, the shape that is bent by the bending portion 11 remains restricted.

  Finally, as shown in FIGS. 9, 12, and 15, when the slide door 3 is in the fully closed position in the front direction in the front-rear direction, the wire harness 6 is in the following state. That is, the intermediate portion of the wire harness 6 in the accommodation space 29 is in a state of being in contact with the harness contact portion 12 and the connecting portion 14 of the slider 10, but not in contact with the bending portion 11. Arranged. Even in this state, even when some tensile force in the front-rear direction is generated with respect to the intermediate portion of the wire harness 6, the restriction wall 26 provided in the accommodation space 29 causes the intermediate portion of the wire harness 6 to be The shape is maintained.

  In such a series of movements of the sliding door 3, in the power feeding device 1, the support portion 13 of the slider 10 is formed by the pair of recesses 13 a and 13 b and the opposing end portion of the rail 28 in the storage chamber 21 of the protector 20. It is slidably engaged in the parallel direction via the buffer portion 13g. In other words, the tip of the rail 28 provided in the storage chamber 21 is brought into contact with the recess portions 13a and 13b while pressing the buffer portion 13g of the support portion 13. It moves without rattling by being intervened. At the same time, the slider 10 moves smoothly by the tension spring portion 27.

  Further, it is possible to realize sliding movement in a state where the storage chamber 21 is spatially isolated from the storage space 29 by the isolation portion 22. Here, the wall portion 25 at the boundary position with the accommodation space 29 of the accommodation chamber 21 provided in the housing main body 20a is, for example, a further foreign object to the accommodation chamber 21 when the isolation portion 22 is the first isolation wall. It is configured to serve as a second isolation wall for preventing such contamination. For this reason, the slider 10 can be moved smoothly and reliably, and the wire harness 6 can be reliably guided without obstructing the movement of the slider 10 even if foreign matter or the like enters the accommodating space 29 from the opening 23. Is possible.

  Further, in order to realize a structure in which the support portion 13 of the slider 10 moves in a parallel direction while being engaged with a metal rail 28 provided in the storage chamber 21, the housing body portion 20 a constituting the protector 20. Even if the shape of the housing cover portion 20b changes due to environmental changes such as temperature change or humidity change, or there may be an error in its dimensions, the rail 28 will not be affected. It is possible to guide the wire harness 6 while continuing the movement reliably.

  In addition, although the electric power feeder 1 which implement | achieves the electrical connection structure of embodiment mentioned above demonstrated the case where it applied as what electrically connects between the vehicle body 2 and the slide door 3 of a motor vehicle, a train and an aircraft The present invention can also be applied to the case where the stationary member and the movable member are electrically connected in a movable body such as a facility or a facility having various attractions.

  Further, although the power supply device 1 that realizes the electrical connection structure of the above-described embodiment has been described as being installed on the slide door 3 attached to the left side of the vehicle body 2, it is installed on the slide door attached to the right side of the vehicle body 2. It can also be applied as a power supply device.

  Furthermore, although the electric power feeder 1 which implement | achieves the electrical-connection structure of embodiment mentioned above demonstrated the structure which forms a pair of recessed part 13a, 13b in the support part 13 of the slider 10, and engages with the opposing edge part of the rail 28.
