Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for pushing an electric component, and more particularly to a jig for securely pushing an electric component mounted on an electric junction box to a completely inserted position.

[0002]

2. Description of the Related Art Electrical connection boxes, such as fuse boxes, relay boxes, branch connection boxes, etc., mounted on automobiles include:
A connection portion into which electric components such as a fuse, a relay, and a diode are inserted and connected is arranged on the plane portion. The electrical junction box is attached to the end of the wire bundle during the wire harness assembly process. In the inspection process, the continuity inspection of the wiring path is performed on the connection part for mounting the electrical components while being set on the required workbench. Will be For this reason, usually, after the continuity test is completed, the electric components are mounted on the electric connection box on the workbench. As described above, in a limited space on the workbench, it is difficult to mount electric components by an automatic machine. Therefore, the mounting operation is performed by manually inserting components one by one, or A manual jig is used to pinch and attach them at once.

For example, as shown in FIG. 6, in order to insert and connect the terminal 2a of the plate-shaped fuse 2 to a plurality of connecting portions 1a arranged in the fuse box 1, it is necessary to use a real opening 7-1.
The fuse insertion device 3 described in Japanese Patent Publication No. 556 is used. The fuse mounting device 3 includes a magazine body 3b capable of simultaneously holding a plurality of fuses 2 by operating the operation lever 3a while gripping the grip portion 3a. And the fuse box 1 held by one hand
Of the plurality of fuses 2 held by the magazine body 3b of the fuse mounting device 3 held by the other hand with respect to the connection portion 1a of
Are inserted all at once.

[0004]

The use of the above-mentioned fuse mounting device 3 makes it possible to insert a plurality of fuses 2 in a predetermined arrangement. However, since the insertion operation simply presses the whole of the magazine body 3b holding the fuse 2 directly to the fuse box 1, it takes a lot of effort to reach the complete insertion state, and the pressing force acts uniformly. Since it is difficult to perform the insertion, there is also a possibility that a half-insertion state may occur.

[0005] The present invention has been made in view of the above-described problems, and is intended to replace an electric component manually inserted into an electric connection box with an electric component.
It is an object of the present invention to provide a pushing jig that can be securely pushed to a completely inserted position by using a lever action.

[0006]

In order to solve the above problems, the present invention inserts a plurality of electric components having terminals corresponding to the connection portions into connection portions arranged on the plane of the electric connection box. This is a pushing jig for pressing the plurality of electric components at a time when the electric components are mounted on the electric connection box, and a hook piece that can be hooked on the bottom surface of the electric connection box is projected. A supporting member that is provided, a pressing member that is supported by the supporting member so as to be able to move in parallel in a direction facing and separating from the hooking piece, and has a lower surface side as a pressing surface for the electric component; and one end of the supporting member. And an operating arm having a free end extending to the upper surface side of the pressing member, and a connecting portion for applying an intermediate point of operation of the operating arm to the pressing member. We provide jigs for pushing electric parts.

More specifically, the pressing surface of the pressing member is formed in a region corresponding to the mounting position of the electric component to be mounted on the electric connection box. To form an uneven shape. In addition, one side surface of the support portion from which the hooking piece projects is a positioning surface for abutting the side wall of the electric connection box to position the pushing jig.

According to the above configuration, when the hook is hooked on the bottom surface of the electric connection box in which electric components have been inserted in advance, and the free end of the operating arm is pushed down, the operating arm makes the support column a fulcrum. The pressing force is applied to the pressing member via the connecting portion by the boosting action of the lever. This causes the pressing member to move downward in the insertion direction of the electric component, so that the upper surface of the electric component is pressed by the pressing surface on the lower surface, and the electric components are forcibly moved to a predetermined fully inserted position. You can push it.

It is preferable that the connecting portion is constituted by a roller rotatably attached to one of the operating arm and the pressing member. With this configuration, when the rotational movement of the operating arm is converted into the linear movement of the pressing member, the rotation of the roller can smoothly transmit the force, and the operability of the pushing operation by the operating arm can be achieved. Can be improved.

The pressing member may be urged by a spring or the like in a direction away from the hooking piece. According to this, since the pressing member can be always held in the standby position at the raised position, the pressing member does not become an obstacle when the pressing member is fitted to the electric connection box, and the workability of the pressing preparation work can be improved. .

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a pushing jig 13 for pushing a plurality of electric components 12 inserted at a previous stage into a connection portion 11a arranged in a plane of an electric connection box 11 to a completely inserted position. . This pushing jig 1
3 is a column portion 14 for holding the electric connection box 11 and a plate-shaped pressing member 15 for pushing the electric components 12 at once.
And an operating arm 16 for pressing the pressing member 15 in the insertion direction of the electric component 12 by leverage, and a connecting portion 17 for interlocking the operating arm 16 and the pressing member 15. In the present embodiment, as the electric component 12, as shown in FIGS.
An example is shown in which the present invention is applied to a plate-shaped fuse having a male tab 12a connected to the fuse box and is applied to a fuse box as the electric connection box 11.

The support portion 14 is formed of a vertically long rectangular columnar member, and has an L-shaped hooking piece 14a which projects at a lower end portion in a horizontal direction so as to hook on a bottom portion of the electric connection box 11 and then refracts upward. And a hooking piece 14a is provided in the middle part.
The bearing portions 14b protrude on both sides perpendicular to the direction of protrusion. In addition, the hook 14
One side of the side on which a protrudes is a positioning surface 14c for abutting the side wall of the electric connection box 11 to position the pushing jig 13.

The lower surface of the pressing member 15 is the electric component 1.
2 is formed in a shape corresponding to the arrangement area of the electric components 12 in the electric connection box 11 as the pressing surface 15a. At one end of the pressing member 15, a guide groove 15b to be fitted to the column 14 is formed, and guide holes 15c are formed on both sides of the guide groove 15b. This guide hole 1
As shown in FIG. 2, a slide shaft 18 composed of a bolt is inserted into the 5 c from above, and the lower end of the slide shaft 18 is screwed and fixed to the bearing 14 b of the support 14. In this manner, the pressing member 15 is supported along the support portion 14 so as to be able to move in parallel in a direction in which the pressing member 15 faces and engages with the hooking piece 15a. Further, a compression coil spring 18a wound around the slide shaft 18 is interposed between the bearing portion 14b and the pressing member 15, so that the pressing member 15 is normally urged to be in a standby state.

The operating arm 16 has a base 16a and a grip 16c made of a metal plate having one end fixed to the base 16a with a bolt 16b. A notch 16d is formed at one end of the base 16a so as to be fitted to the upper end of the support 14 in the same manner as the pressing member 14, and is attached by a supporting shaft 16e so as to be rotatable on the same plane as the sliding plane of the pressing member 15. The free end side of the operation arm 16 extends to the upper surface of the pressing member 15. In this manner, the operation arm 16 is moved to the support shaft 16e.
As a fulcrum, the grip 16c as a point of force, and an intermediate point thereof as a point of action.

The connecting portion 17 is provided at the free end of the base 16a, which is the point of action of the operating arm 16. On the base 16a, a pair of support pieces 17a integrally projecting toward the pressing member 15 side are provided side by side in the width direction.
A roller 17b that is rotatable on the same plane as the operation arm 16 is mounted between the pins 7a via a pin 17c. The roller 17b contacts the upper surface of the pressing member 15 by rotating the operation arm 16 toward the pressing member 15, and the operation arm 1
6 acts to convert the rotational motion of the pressing member 15 into a linear motion.

Next, a process of pushing the electric component 12 into the electric connection box 11 by using the pushing jig 13 having the above structure will be described. During the inspection process of the wire harness, on the workbench, a plurality of electric components 12 are connected one by one to the connection portion 11a of the electric connection box 11 to which the large number of wire bundles W are connected, or an insertion jig is used. Many are inserted simultaneously by hand. In this state, there is a possibility that each of the electric components 12 is electrically connected to the connection portion 11a, but may not reach the completely inserted position without fail.

Next, as shown in FIG.
1 is gripped by one hand with the connecting portion 11a facing upward.
Then, holding the grip 16c of the operation arm 16 with the other hand,
At the same time, the hook 14a of the support 14 is hooked on the bottom of the electrical connection box 11, and the positioning jig 13 is positioned by bringing the positioning surface 14c into contact with the side wall. In this state, the pressing member 15 is opposed to the insertion region of the electric component 12 at an interval above the insertion region by the urging action of the compression coil spring 18a, and the operation arm 16 is in a preparation state of being pushed obliquely upward. . Then, as shown in FIG.
When the operating arm 16 is pushed down, the operating arm 16 acts as a lever booster mechanism, and the pressing force is applied to the connecting portion 1 which is the point of action.
7, which acts on the pressing member 15 via the roller 17b. Thereby, the pressing member 15 is connected to the slide shaft 1.
8, the electric components 12 are moved in parallel in the insertion direction, and the upper surfaces of the electric components 12 are pressed at once by the pressing surface 15a, so that the electric components 12 are pushed to the fully inserted position.

The above operation can be performed with a light operation force by the lever mechanism of the operation arm 16. In this case, if the grip portion 16c is made of a metal plate having a required elasticity, the excessive pressing of the operating arm 16 after the electric component 12 is pushed by the pressing member 15 to reach the full insertion position is absorbed. It is possible to prevent the electric component 12 from being damaged due to excessive pressing force. After the pushing operation of the electric component 12 is completed, the pushing member is released, and the pressing member 15 returns to the raised position by the action of the compression coil spring 18a. The jig 13 can be easily removed from the jig.

In the above-described embodiment, an example in which the electric component 12 is applied to a plate-shaped fuse has been described. However, the present invention can be applied to other electric components connected by pushing a relay, a diode, or the like. Similarly, the electric connection box 11 is not limited to a fuse box, but can be applied to a relay box, a branch connection box, or the like in which an electric component is inserted and connected to a plane portion. Further, the pressing surface 15a of the pressing member 15 may be formed in an uneven shape corresponding to the height difference of the electric component 12 without being flat over the entire area. Further, the connecting portion 17 for converting the rotational movement of the operation arm 16 into the linear movement of the pressing member 15 may be in sliding contact without using the roller 17b, or may be connected by a link. Furthermore,
The roller 17b as the connecting portion 17 is not limited to the operation arm 16 side, and may be provided on the pressing member 15 side.

[0020]

As is clear from the above description, the jig for pushing an electric component according to the present invention uses a lever mechanism of an operating arm for a plurality of electric components inserted into a connection portion of an electric junction box. It is possible to apply a collective pressing force with the pressing member via the pressing member. As a result, the electrical component in the half-inserted state can be reliably pushed into the fully inserted position, and the operation can be easily performed with one hand holding the operating arm.
