Description will be made with reference to FIG. 2 and, if necessary, FIG. The tip portion 1a of the electric wire 1 cut into a predetermined length is connected to the electric wire 1
It cuts in the direction which intersects diagonally with respect to the length direction (refer to Drawing 2 (a)). The means for cutting is not particularly limited. For example, a cutting tool such as a nipper may be used for manual work. Further, when cutting the electric wire 1 by sandwiching it between the blades like a nipper, as shown in FIG.
It is preferable to apply a blade to the electric wire 1 from the direction perpendicular to the paper surface of (a). The cut portion of the tip portion 1a is indicated by a one-dot chain line.

きる。The wire insertion hole 6 is provided from the large diameter portion 6a side of the waterproof rubber plug 6 in which the tip portion 1a of the electric wire 1 cut diagonally is prepared.
Then, the tip portion 1a of the electric wire 1 is inserted into the waterproof rubber plug 6 (see FIG. 2B). More specifically,
A ridge portion of the tip portion 1a of the electric wire 1 (a ridge line portion that appears in a substantially elliptical shape around the cut surface obliquely cut in the process) is provided on the peripheral edge portion of the inlet portion 6f of the electric wire insertion hole 6c of the waterproof rubber plug 6. While pushing along, the tip portion 1a of the electric wire 1 is pressed in the length direction to push the tip portion 1a into the electric wire insertion hole 6c. Then, the above-mentioned ridge portion of the electric wire 1 bites into the peripheral portion of the inlet portion 6f, and the contact portion 1c pushes the electric wire insertion hole 6c wide (see FIG. 3A), and the electric wire 1 can be inserted.

The waterproof connector 4 is assembled. Moreover, when assembling the waterproof connector 4 including the plurality of electric wires 1, each step may be performed collectively for the plurality of electric wires. In this way, the conductor 2 of the electric wire 1 does not significantly protrude from the surface of the electric wire 1 by cutting the electric wire 1 in a direction that diagonally intersects the length direction in the process, so that the electric wire 1 is inserted. Wire insertion hole 6 when inserting into the hole 6c
Since the inner surface of c does not contact the conductor 2, the inner surface of the wire insertion hole 6c may not be damaged by the conductor 2.

It can be made smaller than the inlet portion 6f of the wire insertion hole 6c, and can be easily inserted. After that, the inserted tip 1
By using a as a guide, the electric wire 1 can be easily inserted into the electric wire insertion hole 6c.

に効果的である。Further, referring to FIG. 3, the electric wire 1 is pushed into the electric wire insertion hole 6c while aligning the corner portion of the tip 1a and the peripheral edge of the inlet 6f of the electric wire insertion hole 6c in the process. Therefore, the wire 1 can be smoothly and lightly inserted while gradually expanding the wire insertion hole 6c by the contact portion 1c and autonomously adjusting the axis of the wire insertion hole 6c and the wire 1. (See FIG. 3 (a)). On the other hand, in the case of inserting the conventional electric wire 1 whose tip is not obliquely cut into the electric wire insertion hole 6c of the inlet smaller than its outer diameter, the pushing force at the beginning of insertion of the electric wire 1 is increased to increase the tip of the electric wire 1. It was necessary to forcibly fit the portion 1a into the wire insertion hole 6c (see FIG. 3 (b)). Therefore, the present invention is particularly effective when the inlet portion 6f of the wire insertion hole 6c is smaller than the outer diameter of the wire 1.

きる。Further, since the tip portion 1a of the electric wire 1 is cut in a direction substantially orthogonal to the length direction of the electric wire 1 in the process, the conductor 2 is evenly projected from the insulating coating 3, and the conductor 2 is attached to the terminal fitting 7. Can be crimped properly. In addition, the cut surface of the electric wire 1 may be crushed in the cutting direction and deformed into a flat shape by the above process. The cut surface spreads in a direction orthogonal to the cutting direction, and the spread portion is easily deformed into a projection shape. If the above-mentioned projection-like deformation is made to substantially coincide with the narrowed portion due to the oblique cutting of the tip, for example, a blade such as a nipper is applied to the electric wire 1 from the direction perpendicular to the paper surface of FIG. 2 (a). When cut, the above-mentioned protrusion-like deformation is less likely to be caught when the electric wire 1 is inserted, and the electric wire 1 can be easily inserted.

に短縮できた。As described above, the electric wire 1 has the electric wire insertion hole 6
Since it is easy to pass through c, the work becomes easier. This ease of work also increases the work speed. Specifically, when the conventional electric wire 1 whose tip is not cut obliquely is inserted into the electric wire insertion hole 6c, it takes 12 seconds to insert one wire. In the case of the electric wire 1 cut into pieces, it could be shortened to 7.5 seconds for inserting one piece.

The core wire 11 and the shield 12 are spirally twisted to be integrated, and an outer coating 13 is applied to the core wire 11 and the shield 12. Connect the twisted wire 10 to the waterproof connector 4 described above.
Is different from the waterproof connector 4 in that the core wire 11 of the twisted wire 10 is used in place of the wire 1 described above, the other configurations are the same. Therefore, even in the case of a waterproof connector using the twisted wire 10,
Parts having the same structure, for example, the waterproof rubber plug 6, the connector housing 5, the terminal fitting 7, etc., will be described with the same reference numerals.

り、上記の電線１と同様に扱うことができる。(2) The exposed core wire 11 and shield 12 are loosened (see FIG. 4B). Since the loosened core wire 11 is bent by twisting, it is straightened (see FIG. 4C). For straightening, for example, the core wire 11 may be sandwiched between the opposing plates and squeezed. As the core wire 11 is straightly extended in this way, the core wire 11 is likely to be subjected to a force in the length direction thereof. Therefore, the core wire 11 is subjected to the wire insertion hole 6 in the step (4) described later.
Even if a pushing force is applied at the time of insertion into c, it becomes difficult to bend and can be handled in the same manner as the electric wire 1.

The cut portion of the tip portion 11a is shown by a one-dot chain line. In addition, when the core wire 11 is stretched in the above step (2), the insulating coating of the core wire 11 may be stretched longer than the conductor (the length of the stretched insulating coating is shown in FIG. c) with dimension E0). Therefore, the cutting position when the tip 11a of the core wire 11 is cut in this step (shown by the length E1 from the tip in FIG. 4D)
So that the conductor reaches the cut surface, for example E1> E
When set to 0, the length of the conductor and the insulation coating of the tip end portion 11a of the core wire 11 can be made uniform at the same time as cutting, so that the portion of the core wire 11 having only the insulation coating and no conductor can be saved. It can be removed without spraying.

Also in this case, the effect of claim 2 can be obtained similarly. Further, when the core wire is extended, including the insulating coating of the core wire extending beyond the core wire of the core wire, the tip end of the core wire is obliquely cut, so that the insulating coating and the conductor at the tip end of the core wire are separated. Since alignment can be done at the same time as cutting, it is possible to eliminate troubles due to extension of the insulating coating generated in the process of repairing the twisting, for example, a trouble that the core wire is easily broken when inserting it into the waterproof rubber stopper without trouble. .
