DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS. The same reference numerals are used for the parts corresponding to those of the conventional example. Embodiment 1 FIGS. 1 and 2 show an embodiment in which the distance between the distal ends of both legs of the removing tool is narrowed, and FIG. 1 shows the removing tool and the control device (electromagnetic relay) removed by the separating tool. FIG. 2 is a perspective view showing a state, and FIG. 2 is a side view showing a state in which the claw of the removal tool is engaged with the control tool. First, in FIG. 1, a detachment tool 3 made of a resin molded product has a pair of elastic parallel legs 1 each having a claw 1a formed at its tip so as to face each other, and a connection connecting these legs 1. Although it has a gate shape composed of a portion 2, both legs 1 are slightly bent inward from the middle, and the portions are formed in an inverted V shape. The terminal 6 of the control device 5 is inserted into a socket (not shown), but in the case of the illustrated embodiment, there is a holding arm for sandwiching the control device 5 from the front and rear (left and right in the drawing), so that the claw 1a of the detachment tool 3 is controlled. It does not engage with the bottom surface of the instrument 5, but engages with engagement projections 7 that are separately formed on the upper front and rear surfaces of the control instrument 5. The control device 5 is a ridge 8.
Is inserted into the socket as a guide and is locked to the socket holding portion via the protrusion 9.

In order to engage the claw 1a of the remover 3 with the engaging projection 7 of the control device 5 as shown in FIG. 2, it is sufficient to apply the claw 1a to the front and rear corners of the control device 5 and push it in. . Since the lower surface of the claw 1a is an inclined surface and the upper surface of the engaging projection 7 is also an inclined surface, the leg 1 is elastically deformed outward by the wedge action of the detached tool 3 pushed in, and the claw 1a is engaged. Engage with the mating protrusions 7 when they get over them. If the connecting portion 2 is held and pulled up in this state, the control device 5 is pulled out from a socket (not shown). Here, the distance A between the inner surfaces of the distal ends of the legs 1 of the removal tool 3 shown in FIG.
It is smaller than the interval B of the outer side surface of the engaging projection 7.
Therefore, in FIG. 2, the leg portion 1 is in a state where elastic deformation is left outside, and the engaging projection 7 is sandwiched by the restoring force. Therefore, even after the control device 5 is removed from the socket, the control device 5 is held in the removal tool 3 in the state of FIG.

Embodiment 2 FIGS. 3 and 4 show an embodiment in which a handle is integrally formed at a connecting portion and a positioning slit is provided on a claw, and FIG. 3 shows a state in which a detaching tool and a control device are separated from each other. FIG. 2 is a side view showing a state in which the claw of the removal tool is engaged with the control device. In this embodiment, in addition to the structure shown in FIG. 1, a rectangular grip 10 extending downward from the connecting portion 2 is integrally formed, and square recesses 10a for finger hooking are provided on both surfaces thereof. The lower surface of the handle 10 comes into contact with the upper surface of the control device 5 when the claw 1a is engaged with the engaging projection 7, as shown in FIG. Further, a slit 11 for alignment is provided in the vertical direction at the center of the claw 1a in the width direction, and the slit 11 is provided on the engaging projection 7 along the center of the control device 5 in the width direction. It is designed to fit with.

In order to remove the control device 5 from the socket (not shown), the dismounting tool 3 is put on the control device 5 and the claw 1a is engaged with the engaging projection 7 as described in the first embodiment. 11 is fitted to the protrusion 12, and the detachment tool 3 is pushed down by using the protrusion 12 as a guide. As a result, the removal tool 3 is correctly aligned in the left-right direction with respect to the control device 5, and the claw 1a does not engage with the adjacent control device. Further, when the claw 1a reaches the stage of engaging the engaging protrusion 7 in the process of pushing down the detaching tool 3, the lower surface of the handle 10 comes into contact with the upper surface of the control device 5 and stops. Therefore, the nail 1a
It is not necessary to use nerves to prevent the detachment tool 3 from being pushed down too much after the person has passed over the engagement projection 7. In the illustrated embodiment, the case where the claw 1a of the detaching tool 3 is engaged with the engaging projection 7 of the control device 5 to remove the claw 1a is shown.
It goes without saying that the present invention can be applied to the case of engaging with the bottom surface of the.
