Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a molded protector for a wire harness, which is used for accommodating an electric wire group of a wire harness, attaching the wire harness to a vehicle body / device, and holding and fixing an arrangement posture of the wire harness.

[0002]

[Prior art]

 The molded protector for wire harnesses has an elongated groove that is shaped according to the position of the wire harness.The wire protector is housed in the groove, and the locking part protruding from the outer circumference is provided on the body / device side. The structure is such that it is retained in a vehicle body or the like by being locked in a fitting hole or the like. Since the forming protector of a wire harness for an automobile has various changes depending on the vehicle type and the installation location, the installation condition of the wire harness and the relative conditions of the fitting hole of the vehicle body and the forming protector vary. A variety of unique shapes that satisfy the installation conditions are molded and used.

[0003]

[Problems to be solved by the device]

 Since the above-mentioned conventional molding protector for wire harnesses is basically limited in molding of its unique shape, for example, even when the amount of electric wires to be stored is almost the same and the cross-sectional area of the groove is the same, the locking protector is integrally molded. In many cases, they cannot be shared because there are differences such as the standing position of the department. Therefore, it is inevitable that the cost will increase because it is produced in a variety of small quantities and is not commonly used as a part, and moreover, there is a problem that parts management becomes complicated due to the existence of many kinds.

The present invention provides a molded protector for a wire harness that solves the above-mentioned problems of the conventional technology.

[0005]

[Means for Solving the Problems]

 The molded protector for a wire harness of the present invention that solves the above technical problem is "a groove body for accommodating electric wires, having a locking mechanism for connecting the groove ends to each other, and having a large number of clamp locking holes in the wall plate. And a clamp member having locking legs to the clamp locking holes and a locking head to the vehicle body and equipment, and a required groove formed by interconnecting any number of the molded protector units. The structure is characterized in that the clamp member is inserted, locked and combined with an arbitrary clamp locking hole of the long chain protector body.

[0006]

[Action]

 The molded protector for a wire harness of the present invention having the above-described structure has a combined structure of the molded protector unit body and the clamp member having the above-mentioned structure. Therefore, the molded protector unit body is standardized to, for example, 100 m length. These can be connected and assembled into a chain-formed protector body having a groove length necessary for the arrangement. Then, from among the large number of clamp locking holes that are present on the wall plate of the chain protector body, select the position that corresponds to the fitting hole of the vehicle body / device and insert and lock the separate clamp member. By changing the length of the molded protector and the position where the clamp is erected, it is possible to freely assemble various types of molded protectors for wire harnesses that meet the specific arrangement conditions.

【Example】

 Hereinafter, a detailed description will be given based on examples. Referring to FIG. 1 showing an embodiment of the present invention, this embodiment is a molded protector for a wire harness for a side sill of an automobile cabin. In the embodiment, L is 100 pieces) and a leg member is inserted into the clamp locking hole 3 of the wall plate 9 of the molding protector unit 1 of the molding protector unit 1 and a combination of two separate members of the locking clamp member 2. I am sorry.

More specifically, the molded protector unit 1 is shown in FIGS. 1B and 1D, and a connecting member including a locking claw 11 provided on one side of the groove end 4 and a locking piece 12 provided on the other side. When the groove ends 4 are joined to each other, the locking claws 11 and the locking pieces 12 are engaged with each other to be connected and locked to each other, so that the straight chain protector body 10 having a straight shape satisfying the required total length is provided. It can be formed. Since the molded protector unit 1 of the present embodiment is for a side sill of a vehicle cabin, one surface of the wall plate 9 is attached to a lock lid 14 which is opened and closed by a hinge portion 13 and which has a lock portion 15 at its tip. When the lock lid 14 is closed, the wall plate 9 formed by the lock lid 14 becomes a locking surface for a fitting hole (not shown) of the vehicle body. The lock lid 14 is provided with a large number (10 in the figure) of clamp locking holes 3 arranged at a substantially uniform pitch.

On the other hand, referring to FIGS. 1A and 1C, the clamp member 2 includes a locking head 5 that is fitted and locked in a fitting hole of a vehicle body, and a clamp locking hole at both ends of the locking column 7. 3 has a both-end locking structure having a locking leg 6 which is fitted and locked to the clamp locking hole 3, and when this locking leg 6 is snapped into the clamp locking hole 3, the locking leg 6 becomes a clamp locking hole. It is adapted to be retained and fitted in the locking member 3 and to be locked in a posture in which the locking head 5 is projected from the wall plate 9 of the molded protector unit 1. The locking head 5 and the locking leg 6 of this embodiment are the locking portions of a known wire harness clamp which is composed of a pair of elastic locking pieces 17 that open from the ends of the locking columns 7 in an open leg shape. The clamp member 2 has the same shape, and when the locking leg 6 is fitted into the clamp locking hole 3, the clamp member 2 is pressed against the wall plate 9 to prevent the rattling of the clamp member 2. A piece 8 is attached.

Then, a required number of molded protector unit bodies 1 are connected to each other and assembled to a chain-formed protector body 10 having a straight shape of a required length, and the wire harness 16 is inserted into the chain-formed protector body 10. After that, the lock lid 14 is closed and locked, and the clamp member 2 is inserted and locked in the clamp locking hole 3 group of the lock lid 14 at a position suitable for the installation condition on the vehicle body. Used as a molded protector for wire harnesses. The above-mentioned embodiment has the above-mentioned action, and by the combined set of the molded protector unit body 1 and the clamp member 2 of the same shape, the total length of the groove body and the clamp standing position are made various, and the arrangement conditions Can be used as a molding protector for different wire harnesses.

The molding protector of the present invention is not limited to the above embodiment, and as shown in FIG. 2, a molding protector unit 1A having a straight groove is formed to form a molding protector unit 1 having a straight groove. 3 or, as shown in FIG. 3, a clamp member 2 having a pressure contact piece 8 for individually pressure contacting the molded protector unit body 1 side and the vehicle body side is used, or the locking head 5, the locking leg 6, The connecting and locking mechanism of the molded protector unit 1 may be changed to another structure.

[0012]

[Effect of device]

 As described above, the molded protector for a wire harness of the present invention can be used in a form suitable for various installation conditions by combining a standardized molded protector unit and a clamp member. As a result, it is possible to reduce the cost by promoting the mass production of small types of protectors for wire harnesses, and to reduce the number of types of molding units to improve the manageability of parts.
