JP 2007-66994 A

  This type of shield conductor is disposed under the floor of an automobile, and the distance at which the shield conductor is disposed may be very long depending on the vehicle type. Since the shield conductor needs to be stored after manufacture or transported to an automobile assembly plant, such a long total length requires a long storage space and is expensive to transport. There was a problem of becoming.

  The present invention has been completed based on the above situation, and an object thereof is to provide a shield conductor that can be made compact during storage and transportation.

  The present invention is a shield conductor in which a conductor is inserted through a metal pipe, and the metal pipe is divided and the divided portion is connected or separated by a connection member. Is provided with a metal shield part that surrounds and shields a portion of the conductor that is disposed at the parted portion, while connecting the separated ends of the metal pipe in a conductive state in the connected state. It has the characteristics in the place.

  According to such a configuration, the shield conductor can be folded by bending the portion of the conductor that is disposed in the metal pipe dividing portion, with the dividing portion of the metal pipe being separated. Therefore, the metal pipe can be folded at the time of storage or transportation to shorten the overall length of the shield conductor and make it compact. In addition, when the metal pipe is separated, the shield portion provided in the connection member shields the portion of the conductor that is disposed at the metal pipe, and the metal pipe is not divided. Compared with the power transmission body, it has the same shielding effect.

  The connecting member is formed by fitting the divided end portion of the metal pipe with the pipe fitting portion that can be fitted and detached, and the divided end portion of the metal pipe and the pipe fitting portion. It is good also as a thing provided with the crimping | compression-bonding part which can hold down a fitting part. Thereby, since a shield part and the edge part of a metal pipe can be connected firmly, the shield performance of the parting part of a metal pipe can be ensured reliably.

  The crimping part is formed in a pair of assembling members that can be assembled to each other by sandwiching a fitting part between the divided end of the metal pipe and the pipe fitting part. Is formed with a through-hole penetrating in the direction in which the fitting portion is sandwiched in a state in which both the assembly members are assembled. It may be pressed. Accordingly, when the screws are tightened in a state where the pair of assembly members are assembled, the crimping portions of both the assembly members press the pipe fitting portion and the end portion of the metal pipe, and firmly connect them.

  The metal pipe may be used by being fixed to a vehicle, and the through hole may have a shape capable of inserting a screw that can be fixed to a fixed portion of the vehicle. According to such a configuration, a pair of assembling members are put into an assembled state, and a screw that penetrates the through hole is screwed to the fixed portion, whereby the divided end portion of the metal pipe and the pipe fitting portion are Are firmly connected and the metal pipe is fixed to the fixed portion. Therefore, the work of firmly connecting the shield part and the end of the metal pipe and the work of fixing the metal pipe to the fixed part can be performed at a time, so that the workability can be improved. Further, since the connecting member also serves as a fixing member for fixing the metal pipe to the fixed portion, the number of parts can be reduced by the amount that the fixing member is unnecessary.

  The shield part is composed of a pair of shield halves that form a cylindrical shape when combined, and the connection member is composed of a pair of connection halves formed integrally with the shield half and the assembly member. When the pair of connection half-parts are in the non-assembled state, the divided part may be in a separated state, and when the pair of connection half-parts are in the assembled state, the divided part may be in a connected state. .

  The pair of connection halves may be provided with a lock portion that locks the pair of connection halves in an assembled state. Since one of the connection halved parts can be held in the assembled state by the lock portion, it is possible to easily insert a screw into the through hole and fix the metal pipe to the fixed portion.

  The contact surfaces that can contact each other in the assembled state of the pair of connection halved parts are provided with a first seal member that seals between the two contact surfaces, and the pipe fitting portion and the dividing portion The contact surfaces that come into contact with each other in the fitted state with the end portion may be provided with a second seal member that seals between the end portion of the divided portion and the pipe fitting portion. The first seal member and the second seal member provide a seal between the connection halves and between the connection halves and the end of the metal pipe, thereby preventing water from entering the metal pipe. Can do.

  The pair of connection half parts may have the same shape. Thereby, compared with the case where the connection member is comprised by the halved components of a different shape, a number of parts can be decreased.

  According to the present invention, it is possible to provide a shield conductor that can be made compact during storage and transportation.

The first seal member 41 has a pair of long sides 41L disposed on the upper surface of the contact plate 36 and a pair of short sides disposed on the inner peripheral surface of the fitting recess 33 or the outer peripheral surface of the pipe fitting portion 23. The part 41R is integrally formed (see FIG. 6). The pair of short side portions 41R are arranged at both ends in the longitudinal direction of the pair of long side portions 41L, and project in opposite directions in a semicircular shape. The first seal member 41 is fitted into one of the first groove portions 42 of the pair of connection half-parts 21. When the mating connection half-part 21 is assembled, the first seal member 41 is fitted into both the first groove portions 42. It becomes a state. Specifically, the long side portion 41L is sandwiched between the contact plates 36 of the pair of connection halved parts 21, and the short side portion 41R is sandwiched between the pipe fitting portion 23 and the fitting recess 33.

In addition, the 1st groove part 42 is formed in the depth dimension which protrudes and accommodates the 1st seal member 41 more than half the thickness.

  Moreover, the pipe fitting part 23 of each connection half component 21 has the 2nd sealing member 43 which seals between the 1st parting edge part 11A or the 2nd parting edge part 11B, and the pipe fitting part 23, respectively. A second groove 44 that can be mounted is formed. The 2nd seal member 43 has comprised the ring shape distribute | arranged along the circumferential direction of the internal peripheral surface (it corresponds to the contact surface of this invention) of the pipe fitting part 23. FIG.

  The second groove portion 44 is formed on the inner peripheral surface of the pipe fitting portion 23. The second groove portion 44 is an edge portion on the opposite side to the side where the first short side groove 42P of the first groove portion 42 is formed in the pipe fitting portion 23 (an edge portion on the side protruding from the assembly member 31). In FIG.

  The pair of connection halved parts 21 are attached by forcibly fitting the first divided end portion 11A or the second divided end portion 11B to the pipe fitting portion 23. Hereinafter, the connection half part 21 attached to the first divided end part 11A is referred to as a first connection half part 21A, and the connection half part 21 attached to the second cut end part 11B is referred to as the second connection half part 21A. This is referred to as split component 21B.

  In a state where each of the connection halved parts 21 is attached to the first divided end portion 11A and the second divided end portion 11B, the second seal member 43 attached to the second groove portion 44 is connected to the pipe fitting portion 23. The first divided end portion 11A or the second divided end portion 11B that is forcibly fitted is crushed, and the inner peripheral surface of the pipe fitting portion 23 and the first divided end portion 11A or the second divided end portion 11B. It is in close contact with the outer peripheral surface and sealed between the two. Further, the first divided end portion 11A is in contact with the first conduction portion 24A of the first connection half-part 21A, and the second division end portion 11B is in contact with the first conduction portion 24A of the second connection half-part 21B. It has become.

  When the shield conductor W of the present embodiment is stored or transported to an assembly factory, the first connection half part 21A and the second connection half part 21B are not assembled to each other (first divided end portion). 11A and the second divided end portion 11B are separated from each other), and the portion between the first divided end portion 11A and the second divided end portion 11B (the portion of the electric wire 10 exposed between them) is bent. Then, the shield conductor W is folded. As a result, the overall length of the shield conductor W can be shortened to a length that is approximately half of the routing path of the shield conductor W. Here, in the conventional shield conductor, the shield conductor is bent in advance along a predetermined routing route in a harness manufacturer's factory, and then is often transported to an automobile manufacturer's assembly factory. When the shield conductor routing route extends from the device provided in the engine room at the front of the vehicle body to the device disposed at the rear of the vehicle body, the total length of the shield conductor becomes very long. For this reason, a long space must be secured for storage, and a dedicated rack capable of loading such a long shield conductor must be used for transportation. It will increase.

  However, in the present embodiment, since the shield conductor W can be folded, the shield conductor W is almost half the length when transported or stored from the harness manufacturer's factory to the automobile manufacturer's assembly factory. It is possible to make it compact by folding it to the size. Therefore, it is not necessary to use a dedicated rack or the like at the time of transportation, so that the cost for transportation can be reduced. Further, even when a long storage space cannot be secured, the shield conductor W can be folded for storage, and the space efficiency of the storage location can be improved.

  In addition, since the first connection half part 21A and the second connection half part 21B are forcibly fitted to the first divided end part 11A and the second divided end part 11B, respectively, It is possible to prevent the shield conductor W from falling off when folded or carried.

Then, the shield conductor W transported to the assembly factory in the folded state can be attached to the vehicle as follows.
First, the shield conductor W in a folded state is returned to its original shape (shape along the routing path) to make a connected state. First, both the connection half parts 21A and the second connection half parts 21B are aligned so that the lock pieces 37 and the slits 38 face each other in the vertical direction (assembly direction). 21 is approached. Then, the guide surface 39A comes into contact with the side edge of the facing slit 38, and the lock piece 37 is smoothly inserted into the slit 38 without being caught by the side edge of the slit 38 due to the inclination of the guide surface 39A. When passing through 38, the engaging surface 39B engages with the side edge of the slit 38, and both the connecting halves 21 are locked in the assembled state.

  In the assembled state of both the connection half components 21, each through-hole 35 is arranged in a state of being connected in the vertical direction. In addition, the first seal member 41 attached to the first groove part 42 of the first connection half part 21A or the second connection half part 21B is fitted in the first groove part 42 of the mating connection half part 21 become. Moreover, the pipe fitting part 23 of both the connection half parts 21A and 21B will be in the state inserted | pinched between 34 A of 1st crimping | compression-bonding parts, and the 2nd crimping | compression-bonding part 34B, respectively. Further, the leading end portions of the first divided end portion 11A and the second divided end portion 11B penetrating the pipe fitting portion 23 are sandwiched and contacted by the first conductive portion 24A and the second conductive portion 24B, respectively. become.

  Next, an operation of fixing the shield conductor W to the floor board B of the automobile is performed. First, the shield conductor W is arranged so that the through hole 35 of the connecting member 20 is connected to the screw hole H formed in the floor plate B (see FIG. 9). Then, the screw N is inserted into the through hole 35, and the screw N is tightened into the screw hole H. When the screw tightening operation is sequentially performed for the four through holes 35, the first and second connection half-parts 21 </ b> B further approach as the screws N are tightened, and the first groove portions 42 of the both connection half-parts 21 are brought close to each other. The fitted first seal member 41 is crushed and brought into close contact with both first groove portions 42.

  Moreover, both pipe fitting parts 23 are respectively clamped by the 1st crimping | compression-bonding part 34A and the 2nd crimping | compression-bonding part 34B, and the inner side (the 1st parting edge part 11A and the 2nd parting edge part 11B fit) Is pressed down to the other side). Thereby, the second seal member 43 is further crushed between the inner peripheral surface of the pipe fitting portion 23 and the outer peripheral surfaces of the first and second divided end portions 11A and 11B and firmly adhered to both, The pipe fitting portion 23, the first divided end portion 11A, and the second divided end portion 11B are in a strongly pressure-bonded state. Further, the first divided end portion 11A and the second divided end portion 11B are sandwiched between the first conductive portion 24A and the second conductive portion 24B of each shield half 22 and are in a tightly adhered state. Thus, the shield conductor W is restored to a shape along a predetermined routing path, and the first divided end portion 11A and the second divided end portion 11B are a pair of shield halves 22 (shield portions). As a result, the shield is continuously shielded over its entire length, and has a shield function equivalent to that of the conventional shield conductor W (the shield pipe 11 is not divided). Further, when the screw N is screwed into the screw hole H of the floor board B, the connecting member 20 is screwed to the floor board B of the automobile, and the shield conductor W is fixed to the floor board B of the vehicle.

  As described above, according to the present embodiment, the shield conductor W is formed by bending the portion of the electric wire 10 that is disposed at the split portion of the shield pipe 11 by separating the cut portion of the shield pipe 11. Can be folded. Moreover, when the parting part of the shield pipe 11 is in a connected state, the part of the electric wire 10 disposed at the parting part of the shield pipe 11 is shielded by the shield half body 22 (shield part) provided in the connecting member 20. Compared with a conventional shield conductor in which the shield pipe is not divided, the shield effect is equivalent. Therefore, the shield conductor W can be folded at the time of storage or transportation to shorten the overall length and make it compact.

  In addition, since the locking pieces 37 and the slits 38 are provided, both the connection half-parts 21 are locked in the assembled state (the state in which the through-holes 35 are penetrated). Since it is not necessary to perform the screw tightening operation while holding the connection halved parts so that the position does not shift, the operation can be easily performed. Further, in order to fix the shield conductor W to the floor board B, when the shield conductor W is arranged at a predetermined position, it is not necessary to press the connection half parts 21 by hand so that the both-part halved parts 21 are not detached. Can be done.

  Further, since the two connection half parts 21 can be locked in the assembled state only by bringing them close, for example, the locking parts are separately fitted while holding the both connection half parts in the assembled state by hand. It is possible to easily perform the locking operation as compared with the case where they must be equal.

  Further, when both the connection half-parts 21 are assembled and the screw N penetrating the through hole 35 is tightened into the screw hole H of the floor board B, the both connection half-parts 21 are integrated into the first divided end. The portion 11A and the second divided end portion 11B are firmly connected to the shield half 22 (shield portion), and the shield pipe 11 is fixed to the floor plate B. Thereby, since the operation | work which connects a shield part and the shield pipe 11 firmly, and the operation | work which fixes the shield conductor W to the floor board B can be performed at once, compared with the case where these operations are performed by another process. Thus, workability can be improved.

  Further, since the connecting member 20 also serves as a fixing member for fixing the shield conductor W to the floor board B, no fixing member is required, and the number of parts can be reduced accordingly.

  In addition, since the connection member 20 is constituted by a pair of connection halved parts 21 having the same shape, the number of parts can be reduced as compared with a case where the connection member 20 is constituted by halved parts having different shapes, for example. .

  Further, the first seal member 41 and the second seal member 43 provide a connection between the connection halved parts 21 and between each connection halved part 21 and the first divided end part 11A and the second divided end part 11B. Since it is sealed, it is possible to prevent water from entering the shield pipe 11 and thus reliably prevent the occurrence of electrolytic corrosion.
