Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a method for threading a linear object to be used when, for example, inserting a shield wire into a member having a through hole such as a connector part and performing terminal treatment thereof. Regarding jigs.

[Prior Art] A wire will be described by taking a shield wire as an example. In a shield wire, a generally insulated center conductor of a plurality of cores is wrapped with a metal net for shield, and further insulated. It has an outer cover and is flexible as a whole.

Then, when attaching the connector component or the like to the terminal, the terminal portion is inserted through a member having a push hole of the connector component or the like. At this time, the inner diameter of the through hole usually has little margin with respect to the outer diameter of the shield wire. Therefore, it is difficult to insert a flexible shield wire into such a through hole.

On the other hand, conventionally, the end portion of the shield wire has been heated to cause heat shrinkage, or a lubricating liquid such as oil or soap water has been applied and inserted.

[Problems to be Solved by the Invention] Conventionally, when a terminal portion is heat-contracted by heat-shrinking, or a lubricant such as oil or soap water is applied and inserted, Had to cut that part after insertion, and that part was wasted.If the part was inserted with lubricating liquid, the work of wiping off the lubricating liquid after insertion increased, However, the work is troublesome and the cost is high.

Therefore, the present invention provides a threading jig for a linear object that can be easily inserted through a member having a through hole without reducing the waste of the linear object and can reduce the working cost and the like. The purpose is to

[Means for Solving the Problems] In order to solve the above problems, the present invention is a threading jig for a linear object for inserting a linear object into a member having a through hole, which is inserted into the through hole. A rod-like portion for leading and a plurality of long piece members having openability attached to the rear portion of the rod-like portion and gripping the outer peripheral portion of the linear object to insert the linear object into the through hole. The gist is to have a gripping portion for guiding.

[Operation] First, the leading rod-shaped portion is inserted into the through hole, and then the linear member is inserted into a plurality of openable long-piece members forming the gripping portion to pull the rod-shaped portion, The linear object is tightly gripped by the plurality of long piece members, guided through the through hole, and easily inserted. The heat shrinkage of the end portion due to heating or the application of the lubricating liquid is not necessary, the waste of members is eliminated, and the number of working ports is reduced.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS.

This embodiment describes a case where a shield wire as a linear object is inserted through a component member such as a connector part.

First, the structure of a threading jig for a linear object will be described. In FIG. 1, reference numeral 1 is a leading rod-shaped portion, which is made of a material having appropriate rigidity such as metal or hard plastic and has an outer diameter of It is formed to have a size that allows a through hole described later to be smoothly inserted, and has an appropriate length that can be grasped by hand. On the rear portion of the rod-shaped portion 1, a grip portion 3 composed of a plurality of openable long piece members 2 is attached.

The long piece member 2 is made of a member having spring properties such as a thin plate of hard plastic or a thin metal plate, and its cross section is formed in an arc shape so as to be in close contact with the outer peripheral portion of the linear object, and its outer peripheral surface is easily formed. It is formed on the sliding surface. And, as shown in FIG. 1, it is kept slightly open at all times so that a linear object described later can be easily inserted.

FIG. 2 shows a through hole 4 composed of constituent members such as connector parts.
2 shows a member 5 having a hole and a linear object 6 made of a shield wire, and the member 5 having a through hole is made of plastic in this example.

When inserting the linear object 6 made of the shield wire into the member 5 having the through holes made of the constituent members such as the connector parts as described above, first, as shown in FIG. 1 is inserted through the through hole 4 of the member 5, and the linear object 6 is inserted into the plurality of long piece members 2 which are kept slightly open. Next, when the rod-shaped portion 1 is held by hand and pulled, the linear object 6 is brought into a tightly gripped state by the plural long piece members 2 and guided through the through hole 4, as shown in FIG. 3 (B). , Easy insertion.

As described above, when the jig for threading a linear object of this embodiment is used, heat shrinkage of the end portion of the linear object due to heating or application of a lubricating liquid is unnecessary, and the waste of members is eliminated and the number of working ports is reduced. To do.

By forming the inside of the long piece member 2 in a concavo-convex shape, the gripped state can be further tightened.

[Effect of the Invention] As described above, according to the present invention, the leading rod-shaped portion is inserted into the through hole, and the linear object is inserted into the plurality of long piece members forming the grip portion. When the rod-shaped part is pulled, the linear object is tightly gripped by the gripping part and guided through the through hole.
The linear object can be easily inserted into the member having the through hole without the need for heat shrinkage of the end portion due to heating or application of the lubricating liquid. Therefore, there is an advantage that the waste of members and the work cost can be reduced.
