[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an electric wire protection structure for protecting a connection portion of an electric wire group attached to individual terminals to a connector of the electric wire with a connector connected to a common connector. It is about.

[0002]

2. Description of the Related Art In a wire harness or the like, an electric wire with a connector for connecting an electric wire group having terminals to individual electric wires to a common connector is obtained by inserting a terminal into a connector and pulling out the electric wire group by taping or the like. Be united. However, the terminals inserted into the connector have a slight pitch between the top, bottom, left, and right, so that the wire group drawn out of the connector cannot be immediately bound, and the end of the connector and the wire group binding end. In between, there is a portion of the exposed wire that is unbound and the wire in this portion may be damaged during use. Therefore, as a protection measure for the exposed electric wire portion, there are known examples in Japanese Utility Model Laid-Open No. 56-89127 and Japanese Utility Model Laid-Open No. 58-7478.

That is, in the former known example, a connector cover portion to be fitted to a rear half portion of a connector and a tubular wire wrapping portion for collectively storing a group of wires drawn from the connector are integrated. Provide a switch cover made of soft resin,
The switch cover is covered with the connector and the bundle of wires, so that the exposed wire portion is stored and protected in the switch cover. The connector cover is provided with a connector cover, a connector and a bundle of lead wires are housed in the connector cover, and the exposed wire portion is housed and protected in the connector cover.

[0004]

In any of the above-mentioned known examples, the outer shape of the connector is enlarged due to the structure in which the protective member is covered on the outside of the connector, and the miniaturization is strongly required in a wire harness for automobiles and the like. There is a defect contrary to. Furthermore, since both the switch cover and the connector cover have insufficient position locking force to the connector and the wire bundle and the covering position may be shifted in the longitudinal direction of the wire, the tape to the wire bundle is It is necessary to fix the position by a stop or the like, and it takes time and effort to mount the protection member.
When correcting a wire insertion error to a connector, remove the switch cover or connector cover that has been set and fixed, and then re-attach and set the removed switch cover and so on. Poor workability of work. There are the above problems.

The present invention provides an electric wire protection structure that solves the above-mentioned disadvantages of the prior art.

[0006]

Means for Solving the Problems The wire protection structure of the connector connecting portion of the present invention which solves the above technical problem is a "single unit."
Make a slightly longer length of soft resin tube through which the wires
Cut off the upper half of the tube near the end or front end
Connect the protective tube with the crimp
Attach the crimped part to the terminal
Crimped connection to the terminal together with the electric wire with a rel and fixed
In the state where the terminal is inserted into the connector,
The rear half of the protective tube may come out of the connector.
Made ".

[0007]

[Effect] The electric wire protection structure of the present invention having the above-described structure has terminals
The wire that is inserted and pulled out of the connector is
For protection tube body crimped and fixed to the insulation barrel
As it is in the form of insertion, pull out from the connector
The electric wire is effectively protected. And since the gist of the mounting structure of the protective tube body is used, there is no problem that the connector is enlarged, and furthermore, when a mistake in insertion into the connector is found in a part of the wire group connected to the connector. In this case, it is only necessary to replace the defective wire, and it becomes extremely easy to correct the insertion failure.

[0008] The protective tube body has the above-mentioned pressure.
The attachment part is connected to the electric wire by the insulation barrel of the terminal.
Both are crimped and fixed and connected to the terminals, so the wires and ends
The relative position with the child is stabilized.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of the present invention. That is, in the wire protection structure of the connector connection portion of the present invention, the protection tube body 2 made of a soft resin for connecting the terminal 9 and inserting the wire 1 to be inserted into the connector 7 individually serves as a wire protection member. The protective tube body 2 has a slightly longer length L (in this embodiment, L is about 5) that sufficiently accommodates a portion of the electric wire 1 drawn out of the connector 7 to be protected.
The front end portion is a crimping portion 3 in which the upper half portion of the annular tube is cut out and the lower half portion is left .

Then, the above protective tube body 2 is
(B), a conductor 6 to be crimped with a terminal is inserted and attached to the covering portion 5 of the electric wire 1 exposed at the front end, and thereafter,
The crimping portion 3 is applied to the bottom of the insulation barrel 8 of the terminal 9, and the crimping portion 3 overlapping the covering portion 5 of the electric wire 1 is formed.
Lower half of U-groove insulation barrel 8 lower half
Embracing the upper part of the crimping part 3
Insulate the outer periphery of the wire 1 with the insulation barrel 8
It is on crimped and fixed by pressing the half of the protective Ju
The arm body 2 is connected and fixed to the terminal 9 together with the electric wire 1.

Thus, the wire 1 to which the terminal 9 is crimped is the terminal
9 and the protective tube body 2 are connected in series.
9 is inserted into the connector 7, the first half of the protective tube 2
Part is housed in the connector 7 and the wire 1 is inserted
The back half of the protective tube body 2 goes out of the connector 7
It has a structure. And (see FIG. 1C) this protection
The rear end portion of the tube group 2 is tape-wrapped 1 together with the electric wire 1 group.
0, there is no exposed electric wire 1 between the rear end of the connector 7 and the electric wire bundle 11, and the structure is sufficiently protected by the protective tube body 2 group.

The electric wire protection structure of the embodiment described above is
And the outer shape of the connector does not increase,
The protective member has sufficient locking force to prevent misalignment during use.
And no errors are found in the connector.
When the contact is broken,
Can be easily and quickly corrected.

Next, another embodiment of the present invention will be described with reference to FIG.
An example will be described. That is, the one in FIG.
In the protection tube body 2, near the front end of the protection tube body 2.
Beside, cut out the upper half outer periphery of the tube like a window and cut the lower half outer periphery.
The remaining crimping portion 3 is provided, and the window-shaped cutout portion of the crimping portion 3 is provided.
Put the upper half of insulation barrel 8 into 12
It is designed to be wrapped and crimped.

[0014]

As described above, the electric wire protection structure of the connector connecting portion according to the present invention does not cause the outer shape of the connector to be enlarged. The stability stabilizes the protection function of the electric wire, and further has the effect of improving the workability of correcting a terminal insertion failure.
