Description

  The present invention relates to a wiring restricting device for fixing a wiring and a wiring restricting method using the same.

  Conventionally, wiring in a vehicle is fixed and regulated by a wiring regulation device so as not to be pinched at the time of assembly and so as not to be separated from each other. For example, in the invention described in Patent Document 1, the wiring of the hydraulic control valve is regulated by the rail along the outer peripheral shape of the oil trainer. The rail is formed in a box-like cross-sectional shape with one side open, and the wiring is accommodated inside. In addition, the wiring is fixed to the rail by attaching a holder to a predetermined portion of the rail. And the rail is being fixed to the oil strainer by the fixed nail | claw part.

JP-A-8-163748

However, the invention described in Patent Document 1 has a drawback that the manufacturing cost is high because the cross-sectional shape of the long rail is formed in a box shape and requires a separate holder. In addition, when the rail is formed of an elastic body instead of the separate holder, the wiring may jump out due to vibration.
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a wiring regulation device and a wiring regulation method that suppress the jumping out of the wiring and has good workability.

In order to achieve the above object, a wiring restricting device according to claim 1 of the present invention is arranged such that a wiring is arranged at a predetermined position along a predetermined route having a straight section and a curved section, and the wiring restriction is configured to restrict the movement of the wiring. The apparatus includes a wiring, a wiring housing frame member, a mounting portion, a cable tie, and a caulking portion. The wiring accommodating frame member forms a shape along a predetermined path having a straight section and a curved section, and accommodates the wiring. The predetermined route means a route designed in advance for arranging the wiring. The attachment portion protrudes from the side edge portion of the wiring housing frame member, and is for attaching the wiring housing frame member to another member. Here, the other member may be a valve body of a hydraulic control device, for example. Further, the side edge portion means an edge portion of the wiring housing frame member that is provided in the cross-sectional direction of the wiring when the wiring is housed in the wiring housing frame member. The cable tie is for winding the wiring and the wiring housing frame member from the outside and fixing the wiring to the wiring housing frame member. The cable tie is preferably made of, for example, a resin and is excellent in chemical resistance, heat resistance, cold resistance, weather resistance, and radiation resistance. The caulking portion is formed so as to protrude from the side edge portion of the wiring housing frame member in a state before the wiring is restricted. Here, the crimped portion can be formed in, for example, a protrusion shape, a plate shape, or a rod shape.
For this reason, the jumping-out of the wiring can be suppressed by regulating the wiring along the wiring housing frame member using the crimping portion and fixing the wiring to the wiring housing frame member using the cable tie. Here, “fixed” means that the wiring and the wiring housing frame member are integrated so that the wiring and the wiring housing frame member do not move relatively. Further, “regulation” means that the wiring is arranged along the wiring housing frame member.

By the way, when the caulking portion is bent, if the caulking portion presses the wiring, the wiring may be damaged. Therefore, the caulking portion described in claim 1 of the present invention has a base portion connected to one side edge portion of the wiring housing frame member and a tip portion separated from the one side edge portion of the wiring housing frame member. When the caulking portion is bent to the wiring side at the base portion, the tip portion and the other side edge portion of the wiring accommodating frame member are in contact with each other without contacting the caulking portion and the wiring. Here, the one side edge portion and the other side edge portion mean two edges of the wiring housing frame member in the cross-sectional direction of the wiring when the wiring is housed in the wiring housing frame member.
Therefore, it is possible to suppress the caulking part from pressing the wiring when the caulking part is bent. Therefore, it can suppress that wiring is damaged by the press of a crimping part.

  According to the second aspect of the present invention, the wiring housing frame member is formed of the bottom wall and the side wall portion that rises vertically from both ends of the bottom wall at least in the straight section, and the cross section is formed in a “U” shape. . When the cross section of the straight section of the wiring housing frame member is formed in a “U” shape, the wiring housing operation can be easily performed, and the wiring is easily housed and regulated in the wiring housing frame member. In addition, since the cross section of the wiring housing frame member is formed in a “U” shape, when the crimping portion is bent to the wiring side at the base portion, the crimping portion and the tip end portion of the crimping portion are not in contact with each other. The other side edge portion of the wiring housing frame member can easily come into contact.

  According to the third aspect of the present invention, the caulking portion is perpendicular to the bottom wall from the side edge portion of the straight section of the wiring receiving frame member having a U-shaped cross section before the wiring is restricted. Stand up in the direction. Therefore, the front end portion of the caulking portion and the other side edge portion of the wiring housing frame member can be brought into contact with each other by simply pressing the caulking portion without contacting the caulking portion with the wiring. For this reason, it is possible to restrict the wiring to the wiring housing frame member with a simple operation.

According to the fourth aspect of the present invention, the cross section of the curved section of the wiring housing frame member is formed in an “L” shape. For this reason, the wiring accommodated in the wiring accommodating frame member is pressed down by the cable tie which winds the wiring accommodating frame member and the wiring. Therefore, it is advantageous to fix the wiring and the wiring housing frame member using the cable tie, and the jumping out of the wiring can be suppressed.
In addition, a separate part is required by restricting and fixing the wiring using a caulking portion and a cable tie in the straight section of the wiring housing frame member, and fixing the wiring only with the cable tie in the curved section of the wiring housing frame member. And the cost of parts can be reduced.

  For example, the wiring includes a plurality of branch wirings and a connector at a plurality of ends of the wiring. Here, one end of the plurality of branch wirings is combined by one connector, and the other end of the plurality of branch wirings is electrically connected to each connector.

  According to the sixth aspect of the present invention, the wiring is regulated and fixed by the wiring regulation method for arranging the wiring at a predetermined position along a predetermined route having a straight section and a curved section. More specifically, in step 1, the wiring is accommodated in a wiring accommodating frame member formed in a shape along a predetermined path having a straight section and a curved section. In step 2, the wiring is regulated by bending a protruding caulking portion rising in a substantially vertical direction from the side edge of the wiring housing frame member to the wiring side. Step 3 winds the wiring and the wiring housing frame member from the outside using the first cable tie, and fixes the wiring to the wiring housing frame member. In step 4, the wiring housing frame member is attached to another member by the mounting portion protruding from the side edge portion of the wiring housing frame member. Here, the caulking portion has a base portion connected to one side edge portion of the wiring housing frame member and a tip portion separated from the one side edge portion of the wiring housing frame member. In step 2, when the caulking portion is bent to the wiring side at the base, the caulking portion and the wiring are not in contact with each other so that the tip end portion of the caulking portion and the other side end of the wiring housing frame member are in contact with each other. For this reason, the crimping part can form the predetermined shape which can regulate wiring, without contacting wiring. Therefore, it can suppress that a crimping part presses a wiring, and can suppress damage to the wiring by the press of a crimping part.

  Further, when the wiring has a plurality of branch wirings, as shown in the invention according to claim 7, the wiring and the wiring housing frame member are wound around the wiring housing frame member at a predetermined position using the second cable tie. The method further includes the step of adjusting the length of the branch wiring. Here, the step of adjusting the length of the branch wiring may be performed before the wiring housing frame member is attached to another member, or may be performed after the wiring housing frame member is attached to the other member.
