Description

[Detailed Description of the Invention] This invention relates to an attachment/detachment tool, and more specifically, to an electric component attachment/detachment tool for attaching/detaching an electrical component to/from a socket.

In the case of electrical parts such as relays and fuses where multiple parts are installed in a narrow space, other electrical parts may come close to the electrical part to be replaced.
It has the drawback that it is difficult for the operator to access it, and because it is tightly inserted into the socket or holder, it is difficult to attach and detach it properly in such cases.

This invention aims to eliminate the above-mentioned drawbacks, and its features include a pair of clamping and pressing parts that are connected via a pair of hinge mechanisms, and a pair of clamping and pressing parts that are connected to the It has two pairs of locking rods in which clamping parts for locking electrical components in opposing directions are formed symmetrically both vertically and horizontally at both ends of the part, and the opposing distance can be varied using the hinge mechanism as a fulcrum. The present invention provides a component attachment/detachment tool characterized in that an electrical component can be locked and pulled out by any pair of clamping portions at the ends of two pairs of locking rods.

This invention will be described in detail below with reference to an embodiment shown in the drawings.

FIG. 1 is a sectional view of the electric component attachment/detachment tool of this invention, which includes a pair of clamping and pressing parts 1 having a hinge mechanism 2 such as a V-shaped groove formed by casting a relatively hard synthetic resin.
A, 1b are integrated with opposing surfaces that lock onto electrical components at the ends thereof, which are inclined outwardly.
Locking rods 4a and 4b formed symmetrically on the left and right sides are provided,
In the vicinity of the clamping part of this locking rod (taking into account the shape of the electrical component used), in the same direction as the clamping part, the chain line shown in FIG. As shown in the figure, protrusions 6a and 6b are formed, and 7a and 7b in the figure are anti-slip elements with unevenness formed on the ends of the clamping and pressing parts. Fig. 4 shows a modification of this invention in which the shape of the clamping part is slightly modified, and Figs. 5 and 6 show modifications in which the hinge mechanism is made into an arc shape. They have the same function and structure.

The electrical component attachment/detachment tool 8 of this invention has the above-mentioned configuration, and the case where an electrical component is attached/detached to/from a socket using this attachment/detachment tool will be described below.

In FIG. 2, reference numeral 10 denotes an electrical component (a plug-in type fuse). In order to lock the clamping parts 3a and 3b to the wide part 12 of the housing part 11, first place your fingers on both ends of the clamping and pressing parts 1a and 1b. By pinching the hanging hinge mechanism 2 in the direction shown by the arrow, the ends of the locking rods 4a, 4b open as shown by the chain lines, and the gap between the clamping parts 3a, 3b becomes the electrical component 10 to be locked. When the attachment/detachment tool 8 is moved toward the electrical component 10 side at a point where it is opened wider than the wide part 12 of the connector, the locking rod 4 is removed as shown by the solid line in FIG.
a and 4b are elastic or locking rods 4 of the hinge mechanism 2;
By artificially pushing a and 4b in the direction shown by the arrow so that both rods are parallel or more, the clamping part 3
a and 3b are engaged with the wide portion 12.

When performing the above operation, the locking rods 4a and 4b are symmetrical both vertically and horizontally, so either the upper or lower locking rods may be used. In this state, if the electrical component 10 is already inserted into the socket as shown in FIG. 2, by lightly holding the clamping and pressing parts 1a and 1b and pulling upward, the electrical component 10 will be pulled out from the socket and inserted into the socket. When the electrical component 10 is to be attached to the upper surface 13 of the electrical component 10, the protrusions 6a, 6b are pressed against the upper end of the clamping and pressing parts 1a, 1b or the clamping parts 3a, 3b.
The plug 14 can be inserted into the socket 18 by pressing .

When this electric component attachment/detachment tool 8 is not in use, as shown by the imaginary line in FIG.
When the locking rods 4a and 4b are inserted into the mounting hole 16 in which the partition plate 15 is formed, the width of which is slightly narrower than the gap between the locking rods 4a and 6b, the ends of the locking rods come into contact with the mounting holes 16 and are elastically accommodated in the mounting holes.

As described above, this invention consists of a pair of clamping and pressing parts that are connected via a pair of hinge mechanisms, and an electrical component that is integrated with the clamping and pressing parts and locks the electrical component in opposite directions at both ends of the pressing parts. It has two pairs of locking rods having locking portions formed vertically and horizontally symmetrically, and an arbitrary pair of locking portions of the ends of the two pairs of locking rods whose facing distance can be varied using the hinge mechanism as a fulcrum. Since the electrical component can be pulled out, it is electrically safe and easy to insert or remove the electrical component from the socket or holder.Moreover, since the clamping part is symmetrical both vertically and horizontally, the directionality can be improved. Since there are no upper or lower clamping parts, it can be used casually, has a simple structure, can be produced in large quantities at low cost by molding, and can be completely stored when not in use. have
