That is, the pipe 010 is fitted in the recesses 011 and 012 provided on the mating surfaces of the base body 03 and the sandwiching body 04, but since the cylindrical pipe is fitted in the circular hole, the length of the pipe itself is long. Axial movement or rotation about the axial direction is not necessarily prevented.

Therefore, when the cord and the pipe are required to be fixed at a predetermined position and in a predetermined posture, there is a drawback that they are difficult to apply mainly to a portion where a terminal portion of a wire harness is joined to a counterpart conductor.

Even if it is applied to such a place, it is necessary to further align the wire harness terminal portion and fix it with one hand while connecting it to the other conductor with a screw or the like, which is a troublesome work.

If there is not enough space at the connection point, the above work becomes more difficult and the work efficiency is reduced.

Therefore, it is possible to easily and quickly perform the connecting work, and to provide the terminal connecting portion structure in which there is no fear of the harness coming off or the electrical connection failure.

That is, the present invention has a case box and a cover in a connecting portion structure for connecting a plurality of terminal-attached harnesses to a mating terminal connecting conductor to be connected, and sandwiching the harness between the case box and the cover. Thus, while providing a harness holder for holding the terminals in the same arrangement as the arrangement position of the connection conductor, the harness holder is provided with an engaging portion,
By providing the member on which the terminal connecting conductor is arranged with the engaging portion corresponding to the engaging portion and engaging the engaging portion with the engaging portion, the terminal and the terminal connecting conductor are placed at predetermined positions. It is the harness terminal connection part structure temporarily fixed.

A harness holder fixedly holds a plurality of harnesses with terminals in a predetermined arrangement, and the harness holder is engaged with a member in which the terminal connecting conductor is arranged by engagement of the engaging portion and the locking portion, and the terminal and the terminal connecting conductor. Since the and are temporarily fixed at predetermined positions, the subsequent connection work, that is, the work of connecting the terminal at the end of the harness to the mating terminal connection conductor becomes extremely easy.

Further, since the connection between the terminal and the terminal connection conductor after the temporary fixing can be firmly connected by a bolt or the like, it is possible to surely prevent the harness from coming off or the electric connection from being defective.

Embodiment An embodiment according to the present invention shown in FIGS. 2 to 6 will be described below.

This embodiment is applied to a joint box that is mounted on an automobile and that connects a large number of electric wires with terminals of a wire harness.

FIG. 2 is a perspective view showing a state where the cover 3 of the joint box 1 is opened.

The joint box 1 is composed of a U-shaped box 2 and a cover 3 covering the box from above.

When fitting one to the box 2, at the predetermined front and rear positions, as shown in FIG. 4, one claw 22 on the harness holder 10 side is engaged with the lower part of the corresponding claw 23 on the box 2 side, and the other is fixed. Fit the harness holder 10 into the box body 2 so as to rotate downward.

At this time, since the lower surface of the claw 22 and the upper surface of the claw 23 are inclined in the same direction, the claw 22 moves over the claw 23 and the claw 22 and the claw 23 are engaged with each other due to a slight deformation of the side wall of the box 2. Being a box 2
The harness holder 10 is fitted to and temporarily fixed.

This state is shown in FIG. 3, and the harness holder 10 is temporarily fixed to the box 2.

Next, the structure of the harness holder 10 for holding the terminal portion of the cord 8 will be described with reference to FIGS. 5 and 6.

One of the corresponding side walls of the base body 20 and the sandwiching body 21 is connected by a flexible resin connecting member 30 so that the sandwiching body 21 can be rotated and opened and closed.

A protrusion 31 is provided above the claw 22 on the outer surface of the other side wall of the base body 20, and an engaging member 32 is formed so as to project downward on the outer surface of the side wall of the sandwiching body 21 corresponding thereto. A rectangular hole 33 is formed between the edge portion of the side wall and the engaging member 32.

Therefore, when the sandwiching body 21 is closed, the protrusion 31 engages with the engaging member.
It can be locked by being fitted into the holes 33 of 32.

Rectangular notches 35 are formed at three locations on the upper edge of the front wall 20a of the base body 20, and circular notches 36 are formed on the upper edge of the rear wall 20b that faces the front wall 20a.

Inside the notch 35 of the front wall 20a, an engaging member 38 for temporarily fixing is provided upright, which has claws projecting oppositely at its upper end.

The front wall 21a of the holding body 21 is located slightly forward of the front wall 20a of the base body 20, and when the holding body 21 is closed, the front wall 21a and the front wall 20a partially overlap with each other, and the front wall 21a is cut with the lower edge portion of the front wall 21a. A gap is formed between the lower edge of the notch 35.

The rear wall 21b of the holding body 21 has the same front-rear positional relationship as the rear wall 20b of the base body 20, and a circular notch 37 is also formed at the lower edge portion thereof corresponding to the notch 36.

The harness holder 10 has the above-described structure, and the end portion of the cord 8 held by the harness holder 10 is formed by a metal plate having a shape in which the tip 40a bulges annularly and reaches the base end through the neck 40b. The terminal 40 is caulked at its proximal end to the end of the cord 8 by a caulking member 41.

The width of the neck 40b of the terminal 40 is defined by the notch 35 in the front wall 20a of the base 20.
Slightly narrower than the width of.

As shown in FIG. 6, the end portion of the cord 8 is fitted in such a state that the annular tip portion 40a of the terminal 40 is projected forward from the front wall 20a of the base body 20 and the neck portion 40b is fitted in the notch 35.

The crimped portion is locked by a locking member 38 to prevent upward pulling.

Therefore, in this temporarily fixed state, the movement of the terminal 40 in the left-right direction is already regulated, and further, the annular tip portion 40a that bulges left and right is located in front of the notch 35 and the caulking member 41 is located in the rear. The movement before and after the cord 8 is also restricted.

Then, when the holding body 21 is closed (shown by a chain double-dashed line in FIG. 6), the neck portion 40b of the terminal 40 is held in the gap formed by the lower end edge of the front wall 21a of the holding body 21 and the notch 35, and the cord 8 is sandwiched and fixed in the notches 36 and 37 in the rear wall of the base body 20 and the sandwiching body 21.

In particular, since the flat plate neck portion 40b of the terminal 40 is sandwiched from above and below, the vertical movement is prevented and the rotation of the terminal 40 about the longitudinal direction is also restricted. Therefore, the terminal portion of the cord 8 is the harness holder. It will be fixed at 10 in a predetermined position while maintaining a predetermined posture.

When the harness holder 10 holding the terminal portion of the cord 8 in this manner is fitted and temporarily fixed to the mounting portion 9 of the joint box 1 as described above, the terminal 40 of the terminal of the cord 8 is always positioned at a predetermined position. become.

Then, the conductor connecting terminal 50 is fixed to the box 2 side of the joint box 1 in contact with the lower surface of the annular tip portion 40a of the terminal 38 located in this way.

The conductor connection terminal 50 is a rectangular metal plate having a hole in the center thereof and a female screw portion is formed below the hole to match the hole.

Therefore, when the harness holder 10 is fitted into the box 2, the terminal 40 at the end of the cord 8 and the conductor connecting terminal 50 are always overlapped with the central hole thereof aligned, and the joint box 1 is temporarily fixed in this state. Will be.

Therefore, it is extremely easy to penetrate the terminal 40 and the conductor connection terminal 50 with the screw 51 and screw them together.

The state in which the terminal of the cord 8 is screwed in this way is the state shown in FIG. 2, and after that, the cover 3 is covered to complete the connection work.

As described above, according to this embodiment, the harness holder 10 having the cord end portion fixed at the predetermined position and the predetermined posture is fitted to the mounting portion 9 of the joint box 1 and temporarily fixed to the terminal.
The connection of 40 to the conductor is very easy to achieve without the need for any other holding means.

Further, by using the harness holder 10, miswiring is prevented and it is easy to handle, and the working efficiency can be improved.

Since the harness holder 10 is covered with the cover 3 itself, it is also excellent in waterproofness.

In the above embodiment, since the mating conductor connecting terminals 50 are all in the same front and rear position, the three terminals 40 projecting from the harness holder 10 are all projecting to the same extent, but the mating conductor connecting terminals are arranged in the same front and rear position. If this is not possible, it is necessary to lengthen the neck 40b of some terminals 40.

However, if the neck 40b is lengthened, the annular tip 40a of the terminal 40
Losing the effect of restricting the forward and backward movement of the terminal portion of the cord by sandwiching the notch 35 with the caulking member 41,
You will be allowed to move back and forth.

Therefore, in such a case, as shown in FIG. 7, by changing the shape of the harness holder 10 so that the necessary portion of the front wall thereof is projected forward, it is necessary to lengthen the neck portion 40b of the terminal 40. Therefore, the front and rear movement of the cord terminal portion is prevented, and the cord terminal portion can be securely fixed at a predetermined position.

Advantageous Effects of Invention The present invention is that a harness holder fixedly holds a plurality of harnesses with terminals in a predetermined arrangement, and the harness holder is engaged with a member on which a terminal connecting conductor is arranged so that the terminal and the terminal connecting conductor are temporarily placed at predetermined positions. Since it is stopped, the work of connecting the harness is extremely easy, the work efficiency is improved, and the terminal and the terminal connecting conductor can be surely connected to each other, so that the harness can be prevented from being disconnected and the electric connection can be prevented from being defective.
