BRIEF DESCRIPTION OF THE DRAWINGS FIG.
A preferred embodiment of the present invention will be described in detail. FIG.
FIG. 2 is a perspective view showing a use state of the terminal connector fastening body 10 according to the embodiment of the present invention, and FIG. 2 is an exploded perspective view of the wire holder 1 employing the terminal connector fastening body 10 of FIG.

Referring to FIG. 1, a terminal connector fastening body 10 in the illustrated embodiment is attached to an electric wire holder 1. The electric wire holder 1 is implanted on a drawing board on which a wire assembly (not shown) is laid so as to correspond to the wiring position of the wire assembly.
The branch dimension L of the branch wire W branching from the wire assembly can be defined.

Referring to FIG. 2, a wire holder 1 has a base 2 erected on a drawing board on which the wire assembly is laid, and is fixed on the base 2, and the branch dimension L
And a U-shaped engaging portion 3 for positioning the terminal connector C of the branch electric wire W so as to define The base portion 2 is formed in a columnar shape having a circular cross section, and is fixed on the drawing plate by screwing a nut 4 into a screw portion (not shown) at the lower end thereof. Also, at the upper end of the base part 2,
A female screw 5 is formed, and the locking portion 3 described below can be mounted by the female screw 5.

The locking portion 3 is commonly called a "U-shaped member", and is a metal member that connects a pair of standing portions 6 extending substantially vertically in a U-shape. At the lower end of the locking part 3,
The male screw 7 hangs down. The male screw 7 is screwed into the female screw 5 of the base portion 2 so that the locking portion 3 can be integrally fixed to the base portion 2. In the specific example shown in the drawing, the nut 8 is screwed into the male screw 7 in advance, so that the direction around the vertical line of the locking portion 3 can be fixed in a desired posture.

Next, the illustrated terminal connector fastening body 10
A fixed part 11 fixed to the wire holder 1 by being sandwiched between the base part 2 and the locking part 3, and a fastening part 12 continuous with the fixed part 11.
And are integrally provided. In the illustrated specific example, the fixing portion 11 is embodied by a rubber plate material set to a predetermined thickness T, and the insertion hole 1 for inserting the male screw 7 is provided.
Three. Further, in the specific example shown in the drawing, when mounting the terminal connector fastening body 10, the fixing portion 11 is first inserted through the male screw 7 of the locking portion 3, and then the nut 8 is screwed into the male screw 7 with the washer 9 interposed. This prevents the fixing portion 11 from being excessively tightened between the base portion 2 and the locking portion 3.

On the other hand, the fastening portion 12 has a thickness T of the fixed portion 11.
Window 1 with a string-like portion formed in a rectangular cross section
4 is embodied by an annular portion. In the above configuration, as shown in FIG. 1, the terminal connector C is connected to the upright portions 6, 6 with the branch wire W introduced between the upright portions 6, 6 of the locking portion 3 of the wire holder 1. Abutting, fastening part 1
2 is extended, and a window 14 is provided at the free end of each of the upright portions 6,6.
, The terminal connector C is connected to the standing portion 6,
The terminal connector C can be fastened to the locking portion 3 in a state where the terminal connector C is pressed. At this time, the terminal connector fastening body 10
Is formed of elastic rubber, the fastening portion 12
The elasticity makes it possible to absorb the difference in the outer dimensions of the terminal connector C. As a result, regardless of the type of the terminal connector C, the terminal connector C can be fastened to the locking portion 3 with a predetermined tightening strength regardless of the type of the terminal connector C, and versatility can be provided. It has a remarkable effect.

Since the fixing portion 11 is formed of the same material as the fastening portion 12, the fixing portion 11 and the fastening portion 12 are formed.
Can be integrally formed in one step. Therefore,
There is an advantage that the manufacturing cost is reduced. In addition, the fixing part 11 includes the locking part 3 of the wire holder 1 and the base part 2.
As shown in FIG. 1, since the fastening portion 12 has an annular portion (window portion 14) that can be hooked to the free end of the upright portion 6,
As a result of being able to directly attach the terminal connector C with the upright portion 6 substantially released, there is an advantage that the accuracy of the branch dimension L is increased.

In addition to the above-described embodiment, various types of terminal connector fastening bodies can be embodied.
FIG. 3 is a perspective view of the wire holder 1 employing the terminal connector fastening body 20 according to another embodiment of the present invention. As shown in the figure, the terminal connector fastening body 20 is entirely formed of a rectangular elastic rubber plate, and one end of the terminal connector fastening body 20 is engaged with the base 2 of the wire holder 1 as in the embodiment of FIG. A fixing portion 21 sandwiched between the stop portion 3 and a rectangular window portion 22 is formed on the other end side, and a fastening portion 23 that uses the window portion 22 as an annular portion for mounting. Is composed of the rest. Also in this embodiment, FIG.
The same operation and effect as described above can be obtained.

FIG. 4 shows a wire holder 1 employing a terminal connector fastening body 30 according to still another embodiment of the present invention.
It is a perspective view of. As shown in the figure, the terminal connector fastening body 30 is embodied by a string-shaped body formed of elastic rubber. A hook fitting 31 is attached to one end of the terminal connector fastening body 30.
1 and the other end portion 32, the corresponding standing portions 6, 6 respectively.
, And the remaining part is the fastening part 33.
Is composed.

In this terminal connector fastening body 30, the terminal connector C (see FIG. 1) fastened to the fastening portion 33 can be attached and detached by attaching and detaching the hook fitting 31 to and from the corresponding upright portion 6. Therefore, there is an advantage that the attachment / detachment work becomes easy. Although not specifically shown, when the terminal connector fastening body is formed of a string-like body, both ends of the terminal connector fastening body are the same as the other end 32 of FIG.
A configuration that binds to In this case, when attaching and detaching the terminal connector C, it is necessary to extend the fastening portion. However, since the terminal connector C can be fastened with the simplest elastic rubber, the cost is reduced.

The above embodiment is merely an example of a preferred specific example of the present invention, and the present invention is not limited to the above embodiment. For example, the locking portion 2 of the wire holder 1
Is not limited to a U-shape, but may be a comb shape. It goes without saying that various design changes are possible within the scope of the claims of the present invention.

[0022]

As described above, according to the present invention,
Since the difference in outer dimensions of the terminal connector held by the connector holder is absorbed by its own elasticity, the terminal connector can be locked by the locking portion. It has a remarkable effect of having versatility compatible with terminal connectors.

In particular, when the fixing portion and the fastening portion are formed of the same material, there is an advantage that the manufacturing cost is reduced. Further, when the fastening portion can press the terminal connector with respect to the generally released locking portion, there is an advantage that the accuracy of the branch dimension can be more precisely maintained.

Further, when the terminal connector fastening body itself is formed of a string, the terminal connector can be attached and detached only by extending the fastening portion, so that it is inexpensive and easy to attach / detach. There is also the advantage of becoming. further,
When one of the fixing portions of the string is formed with a hook, there is an advantage that the attaching / detaching operation is further facilitated.
