Description

  The present invention relates to a method for holding a connector on a wire harness for an automobile, a holding tool, and a holding structure.

  Wire harnesses for automobiles are arranged in every corner of a vehicle, for example, in an engine room, a door, or a room for the purpose of supplying power and transmitting signals. The automotive wire harness includes a trunk line and a plurality of branch lines branched from the trunk line, and a connector (female connector) is connected to a terminal of the branch line. By fitting the connector of the branch line to a connector (male connector) on the component side, a desired component can be mounted on the wire harness.

  The number of connectors (also referred to as optional connectors) provided on the branch line differs depending on the number of parts according to the type of vehicle and optional equipment, etc., but in order to improve the efficiency of wire harness manufacturing and management In addition, a common method is to reduce the number of wire harness types (part numbers) as much as possible and to make common specifications. In this case, the wire harness includes a number of connectors according to the vehicle having a large number of parts, and an operator selectively uses the necessary connector when assembling the vehicle. Therefore, in the case of a vehicle with a small number of parts, there is a connector (so-called discard connector) that was not used at the time of assembly, and when this discard connector comes into contact with the vehicle body panel or other parts due to vibration during travel, noise is generated. There is a problem that occurs.

  As a countermeasure against this abnormal noise, a holding structure for fixing the connector to the main line has been proposed. For example, Patent Document 1 discloses a holding structure in which an engagement cloth (so-called Velcro (registered trademark) or the like) is attached to both ends of a rubber band, and this holding structure has a connector along a trunk line of a wire harness. In this state, the rubber band is wound around the outer periphery of both of them, and the male engagement cloth at one end of the rubber band and the female engagement cloth at the other end are engaged to fix both.

JP 11-26059 A

  In the case of the above method, as shown in FIG. 5 of Patent Document 1, most of the connector is exposed, and if the exposed portion fixed to the main line comes into contact with the vehicle body panel or other parts, it is different. There is a problem that sound is generated or an exposed part is damaged by contact. Even a throw-away connector may not be damaged because it may be used after it has been delivered once due to additional orders for optional equipment.

  Further, when the connector is selectively used during the assembly operation, if there is an exposed portion in the connector, there is a possibility that the assembly process may be damaged by contact with a tool or the like. Furthermore, when attention is paid to such breakage, there is a problem that the work efficiency of the operator is lowered.

  For this reason, as a means for preventing the exposed portion from being generated, a method is used in which the connector is covered with a protective material formed of a foamed resin sheet or the like, and the covered connector is fixed to the main line with a tape member. FIGS. 1A and 1B are diagrams showing an example of such a conventional technique. FIG. 1A is a plan view showing a state in which a connector 70 is arranged on a protective material 101a (holding tool 101), and FIG. FIG. 6C is a plan view showing a state covered with the tool 101, and FIG. 8C is a plan view showing a state where the connector 70 covered with the holding tool 101 is fixed to the trunk line 30. FIG.

  In the prior art of FIG. 1, first, the terminal of the branch line 50 and the connector 70 connected to the terminal are arranged on the holder 101 having the sheet-like protective material 101a cut into a predetermined shape as shown in FIG. Then, after the holding tool 101 is folded back by the folding line 102, the side edges of the folded holding tool 101 are bonded to each other by the adhesive layer 101 b formed on the side edge of the holding tool 101. After that, the tape member 113 is wound around the outer periphery of the holder 101 that covers the branch line 50 as shown in (B), and the connector 70 is fixed so as not to come out from the opening of the side edge 101d where the adhesive layer 101b is not formed. Next, the connector 70 covered with the holder 101 as shown in (B) is placed along the trunk line 30 as shown in (C), and then both the trunk line 30 and the connector 70 covered with the holder 101 are both. The connector 70 can be fixed to the main line 30 by winding the tape member 15 around the outer periphery of the main line 30.

  When the connector is covered with the protective material 101a in this manner, the exposed portion of the connector does not occur, and thus the above-described problem of occurrence or damage of noise can be solved. However, a certain degree of work accuracy is required, for example, the connector 70 is disposed on the holder 101 while being aware of the positional relationship with the folding line 102 and the adhesive layer 101b. Further, in addition to the requirement for such positioning accuracy, the bonding of the side edge adhesive layer 101b and the winding work of the tape member 113 are also required, which increases the difficulty of fixing the connector 70. . In general, the assembly process of a vehicle is a flow operation by a conveyor, and is a repetitive operation in a short time. Therefore, if the difficulty of the operation increases, the quality of the holding structure for fixing the connector will vary.

  Moreover, the shape of the protective material 101a which is a foamed resin sheet is cut into a complicated shape as shown in FIG. 1A, and the adhesive layer 101b is formed only on a part of the side edge. For this reason, there is also a problem that the price is higher than that of a simple-shaped foamed resin sheet (for example, a sheet that is cut into a rectangle and has an adhesive portion formed on one side). Since the wire harness of an automobile includes a large number of connectors, if the cost of the holder for each connector increases, the high cost of the entire vehicle cannot be overlooked due to the integration effect.

  The present invention has been made by paying attention to the above-described problems, and is capable of suppressing the generation of abnormal noise during traveling, damage to the connector, and the like, as well as a wire harness that can be fixed easily and can be reduced in cost. It is an object to provide a connector holding method, a holding tool, and a holding structure.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 2 is a diagram schematically showing the connector holding structure 10 of the wire harness according to the present invention. FIG. 2 (A) shows the connector 70 connected to the terminals of two branch lines 50 branched from the main line 30 held on the main line 30. 4B is an enlarged perspective view of the holding structure 10 for the connector 70 in FIG. 4A, and FIG. 4C is an enlarged perspective view showing the state in which the connector 70 of FIG. 2B is pulled out from the holding structure 10; FIG.

  As shown in FIG. 2, the connector holding structure 10 according to the present embodiment includes the holder 1 including the protective material 1 a and is supported by being wound around the trunk line 30. The holder 3 is held by winding the holder 1 so as to sandwich the part 3 and the support part 3 and the connector 70. The protective material 1a serving as the base of the holder 1 is not particularly limited as long as it is a flexible, lightweight, low-cost material and has shock buffering properties. A foamed resin sheet made of urethane foam is used.

  The holding structure 10 preferably includes a tape member 15 that surrounds and fixes the outer periphery of the holding portion 5. As will be described later, even if the tape member 15 is not provided, for example, by providing an adhesive layer (second adhesive layer) 1c at the end of the holder 1 of the holder 5, the support portion 3 and the connector The end portion of the holder 1 wound so as to sandwich the 70 can be stably fixed, but by winding the tape member 15 around the entire outer periphery of the holding portion 5, an adhesive layer (second The connector 70 can be stably held and fixed even when the holder 1 in which the adhesive layer 1c is not formed is used. Furthermore, by using both (the second adhesive layer 1c and the tape member 15) in combination, the connector 70 can be more firmly and stably fixed, and even when subjected to strong vibration or impact during traveling. Can be reliably prevented from separating from the holding structure 10.

  In the holding part 5, the holder 1 wound so as to hold the support part 3 and the connector 70 directly covers the branch line connection surface 70 a of the connector 70 to which the branch line 50 is connected as shown in FIG. It is wound so that there is no. That is, among the side surfaces of the holding part 5, at least the side surface on which the branch line connection surface 70a is located is the opening 5a, and the branch line connection surface 70a is connected to the external space through the opening 5a. With this configuration, the operator can pull out the connector 70 through the opening 5 a by pulling the branch line 5. It is possible to use the connector 70 with a simple operation of pulling out.

  The width W1 of the holder 1 in the trunk line direction (the width of the support portion 3 and the holding portion 5 of the holding structure 10) is preferably longer than the width W70 of the connector 70. Thereby, without connecting the branch line connection surface 70a from the opening 5a, the connector 70 is protected by the protective material 1a (the holder 1), and the connector 70 can be easily pulled out from the opening 5a during use.

  On the other hand, in the case of the prior art, as shown in FIG. 1C, the connector 70 is covered with the protective material 101a (the holder 1) as shown in FIG. After removing, it is necessary to take out the connector 70 from the bag-like protective equipment 101, and there are many work steps compared to the case of using the present invention.

  As shown in FIG. 2A, the width W15 of the tape member 15 is preferably smaller than the width W70 of the connector 70. If the width W15 of the tape member 15 is equal to or greater than the width W70 of the connector 70, the fixing by the tape member 15 becomes too strong, and the above-described pulling operation may be difficult when the connector 70 is used. In addition, by forcibly pulling out, a connector lock or the like (not shown) disposed on the side surface 70b of the connector 70 may be damaged.

  Next, a holding method for realizing the above holding structure 10 will be described with reference to FIGS. FIG. 3 is a diagram schematically showing an embodiment of a connector holding method, a holder, and a holding structure of a wire harness according to the present invention. In the embodiment of FIG. 3, the holder 1 includes a protective material 1a of a foamed resin sheet made of a rectangular foamed urethane as shown in FIG. The holder 1 and the trunk line 30 are fixed by winding one end portion in the longitudinal direction of the holder around the trunk line 30 as shown in FIG. 3B (main line supporting step). In the holding structure 10, the portion fixed to the main line 30 by the main line support process is the support portion 3.

  The fixing method at this time is not particularly limited as long as it is a method that can be carried out by a simple operation, and can be fixed by simply winding the protective material 1a around the main line 30 multiple times. For example, FIG. As shown in (B), when the protector 1 in which the adhesive layer 1b is formed in advance in a part of the region of the protective material 1a in contact with the trunk line 30 is used, the holder 1 and the trunk line 30 are connected by the adhesive layer 1b. Adhesive fixing is possible, and convenience is high. In FIG. 3, the adhesive layer 1 b is formed in a region corresponding to the length of one turn of the trunk line 30 from one end of the protector 1, whereby the holder 1 is spread over the entire outer peripheral surface of the trunk line 30. Since the main line 30 can be bonded, it can be firmly fixed.

  Next, as shown in FIG. 3C, the connector 70 is disposed on the outer peripheral surface of the holder 1 that is wound and fixed to the main line 30, and the main line 30, the support portion 3, and the connector 70 are sandwiched. The center portion and the other end portion (end portion not fixed to the main line 30) are wound (connector holding step). In the holding structure 10, the portion in which the holding tool 1 holds and fixes the connector 70 with the support portion 3 held by the connector holding step is the holding portion 5.

  The other end of the holder 1 (the end not fixed to the main line 30) may be provided with an adhesive layer (second adhesive layer) 1c, whereby, as shown in FIG. After the rotation, the terminal end (the other end) of the holder 1 can be bonded and fixed. The second adhesive layer 1c only needs to be provided at the end of the region where the holder 1 is wound and holds the connector 70. In FIG. Although it is formed at the end of the surface, it is not limited to this. For example, the second adhesive layer 1c may be bonded and fixed by being provided at the end of the radially outer surface and slightly bending the end inward.

  However, it is assumed that the portion of the holder 1 in the holding portion 5 that contacts the connector 70 does not include an adhesive layer. If the holder 1 adheres to the connector 70, the connector 70 cannot be easily pulled out from the holding structure 10 when the connector 70 is used.

  FIG. 4 shows another embodiment according to the present invention. In the embodiment of FIG. 4, the holder 1 is provided with a protective material 1 a of a foamed resin sheet made of rectangular urethane foam as shown in FIG. 4A as a base, and an adhesive layer 1 b is provided on the entire surface of one surface. Have. As shown in FIG. 4A, when the trunk line 30 is arranged at the center of the surface of the holder 1 having the adhesive layer 1b and is folded so that both ends of the holder 1 are substantially coincident with each other, the holder 1 is folded in half. The trunk line 30 can be clamped in the central part. The holder 1 is fixed in a folded state by the adhesive layer 1 b, and the adhesive layer 1 b at the center of the holder 1 and the main line 30 are bonded and fixed (main line support process), and the support part 3 is fixed to the main line 30. Is formed (FIG. 4B).

  Thereafter, as shown in FIG. 4C, the connector 70 is disposed on the outer peripheral surface of the holder 1 of the support portion 3 fixed to the trunk line 30, and is wound so as to cover the connector 70 with the holder 1 folded in half. In the holding structure 10, a portion in which the two-folded holding tool 1 holds the connector 70 while holding the connector 70 with the support portion 3 becomes the holding portion 5.

  The end of one surface of the holder 1 (the surface that does not have the adhesive layer 1b) may include an adhesive layer (second adhesive layer) 1c as shown in FIG. As shown to 4 (C), the terminal end of the holder 1 overlapped in two after winding can be bonded and fixed. It should be noted that the ends of both ends of the holder 1 do not necessarily need to be completely matched as shown in FIG. 4B, and the adhesive layer 1b may be bonded to each other by slightly shifting the longitudinal position of the holder 1. good. Thereby, the adhesive layer 1b in the mismatched portion can have the same role as the above-described end adhesive layer (second adhesive layer) 1c. That is, when the adhesive layers 1b are bonded to each other, if the adhesive layer 1b at the end of the lower protective material 1a in FIG. 4B is slightly exposed, the protective material on the radially outer side in FIG. The end of 1a (the end of the holder 1 after winding) can be bonded and fixed by the exposed adhesive layer 1b.

  Note that the adhesive layer 1b does not necessarily have to be formed on the entire surface of one side of the holder 1, and can be bonded and fixed as long as it is formed at the central portion that sandwiches the trunk line 30 and a part of the portion where the holder 1 overlaps. However, from the viewpoint of the manufacturing cost of the holder 1, it can be said that the adhesive layer formed on the entire surface is more advantageous because it is easier to manufacture.

  The area | region which contacts the connector 70 among the holders 1 in the holding | maintenance part 5 shall not be equipped with the contact bonding layer like embodiment of FIG. If the holder 1 adheres to the connector 70, it cannot be easily pulled out from the holding structure 10 when the connector 70 is used.

  If the outer periphery of the holder 1 (holding portion 5) is further surrounded by the tape member 15 with respect to the holding structure 10 realized by the holding method shown in FIG. 3 or FIG. 4 in this way (second connector holding step) ), The connector 70 can be stably held and fixed (FIG. 2B).

  According to the present invention realized as described above, since the connector 70 is covered with the holder 1, the connector 70 comes into contact with the vehicle body panel, other parts, etc. due to vibrations during traveling, and abnormal noise is generated. And the connector 70 is prevented from being damaged.

  Further, the shape of the holder 1 to be used may be a simple shape (rectangular shape) as shown in FIGS. 3 and 4 as compared with the prior art in FIG. 1, and the cost of the holder 1 can be reduced. . Furthermore, as shown in FIG. 4, when the adhesive layer 1b is formed on the entire surface of one side, a foamed resin sheet having a general specification can be used as the holder 1, so that the protective device as shown in FIG. Compared with the case where the adhesive layer 1b is formed only on a part of the first layer, the cost can be further reduced. In addition, it is also possible to use the foamed resin sheet which does not have the contact bonding layer 1b and the 2nd contact bonding layer 1c by using the tape member 15 separately, in that case, as a foamed resin sheet, it is one layer. An inexpensive one can be used.

  Further, in the fixing operation, since it is a simple holding method in which the trunk wire 30 and the connector 70 are wound around one sheet-like holder 1, there is no requirement for positioning accuracy as in the prior art of FIG. 1, and the operation is easy. is there. In particular, when using the holder 1 having no adhesive layer, or when using the holder 1 having the adhesive layer 1b formed on the entire surface as in the embodiment shown in FIG. Since it is not necessary to pay special attention to the positioning of 30, the required work accuracy is much lower than that of the prior art of FIG. As a result, an operator can efficiently fix the connector 70 in the assembly process, and variations in the quality of the holding structure for fixing the connector can be suppressed.

  On the other hand, when the connector 70 is used, it is only necessary to pull out the connector 70 from the holding structure 10, and the workability at the time of use is better than that of the prior art.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to above-described embodiment, In the range which does not deviate from the summary, it can implement variously. For example, in order to improve the impact resistance of the holder 1, the holder 1 may be configured to wind the connector 70 and the support portion a plurality of times. Moreover, the holder 1 may have a multi-layer structure in order to improve impact resistance, and can be variously selected depending on the application.
