Abstract

(57) [Summary] [Purpose] To provide a protector that facilitates adhesion to harness wires. [Structure] Provided on the inner surface of the center hole 2 through which the harness electric wire A is inserted are sealing projections 6 which are in close contact with the outer circumference of the electric wire and seal both ends of the protector bonding area a. Since the adhesive injection hole 7 is provided therethrough, the adhesive can be easily and accurately injected into the interface of the adhesion region a.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a three-dimensional protector that is attached to a protected portion of a harness wire for the purpose of preventing the harness wire of an automobile from being damaged by a fixture and improving the bending durability of the wire.

[0002]

[Prior art]

 FIG. 1 shows a conventional example of the protector described above. The protector 1 is made of an elastic material such as rubber or flexible resin, and the harness wire A is passed through the center hole 2. Reference numeral 3 is an attachment portion of the wire fixing tool, and 4 is a cone portion that gradually increases the bending rigidity of the electric wire toward the fixing portion side. The area a on the attachment portion side is covered with the adhesive 5 to cover the wire A. Glued to. On the other hand, it is not desirable to bond the remaining area b in order to allow sliding with the electric wire due to bending.

In this conventional protector, the adhesive interface portion of the adhesive region a is filled with the adhesive agent 5 by a method of pouring the adhesive agent through a gap in the portion a in the figure.

[0004]

[Problems to be solved by the device]

 The conventional protector, which injects the adhesive from the gap between the wire at the entrance and exit of the center hole, has two cones 4 at opposite ends. It was very difficult to inject the adhesive into the adhesive interface part of the region a.

Further, even when the injection can be performed from the portion (a) as shown in FIG. 1, since the clearance at that portion is small, it is necessary to adopt a method such as widening the inlet to perform the injection, which makes the work difficult. There was a problem called.

The present invention is intended to provide a protector for a harness electric wire that solves the above problems.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, in the protector for electric wire of the present invention, an annular seal is provided on the inner surface of the center hole through which the harness electric wire is passed, which closely adheres to the outer circumference of the electric wire and seals both ends of the protector attachment area for the electric wire. The projections for use were provided, and the adhesive injection hole was made to penetrate from the outside to the center hole in the trunk of the protector between the sealing projections.

[0008]

[Action]

 The adhesive is injected into the adhesive interface between the center hole and the harness wire through the injection hole provided in the body of the protector. The injected adhesive does not flow into the adhesion prohibition area because both ends of the adhesion area are sealed by the sealing projections. The adhesive can be injected into the required area without widening the interface entrance, and the adhesive can be injected into the area where there are no adhesion areas on both sides of the adhesive area.

[0009]

【Example】

 FIG. 3 shows an example of the protector of this invention. This protector 1 is made of the same material as the conventional product. The external shape is almost the same as the conventional product. That is, in the bidirectional protector shown in the drawing, the mounting portion 3 of the wire fixing device is provided at the center, and the cone portions 4, 4 are continuously provided on opposite sides of the mounting portion 3 in opposite directions.

The protector 1 is characterized by an element that characterizes the present invention. An annular sealing projection 6, 6 is provided on the inner surface of the central hole 2 to closely contact the outer periphery of the harness wire A and seal both ends of the bonding area a. Further, an injection hole 7 for an adhesive is provided in the body between the seal projections at both ends of the region a, and the body is radially penetrated through the body.

It should be noted that each of the sealing projections 6 and 6 may be arranged in a plurality as shown in FIG.

Further, a protector to which the present invention is applied may be as shown in FIG. 5 or FIG. FIG. 5 shows a unidirectional one in which the cone portion 4 is provided on one side, and FIG. 6 does not have the cone portion 4, that is, it is used only for the purpose of protecting the mounting portion of the wire fixing device.

[0013]

[Effect of device]

 As described above, the protector of the present invention is provided with the sealing projections and the adhesive injection holes for closing both ends of the adhesive region, so that the adhesive can be easily injected and the efficiency of the adhesive work can be improved.

Further, even with the bidirectional protector, there is no obstacle to the injection of the adhesive, and stable adhesion can be achieved.

Furthermore, since the injected adhesive does not flow into the adhesion prohibition region, the quality of the protector by the protector is improved.
