DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric device having no lock mechanism, such as a relay switch, which is mounted on an electric device provided with a lock mechanism, for example, a relay box so as not to come out, and is easily extracted as necessary. The present invention relates to a jig for extracting electric parts and a method for extracting the electric parts, which are configured so as to be able to carry out the above.

[0002]

2. Description of the Related Art Various electrical components such as fuses and relay switches are frequently used in electrical junction boxes mounted on automobiles and the like. These electric components are fixed in the electric junction box so as not to come off due to vibrations or the like while the automobile is running, but are removed to replace them with new electric components during maintenance. Therefore, the mounting structure of the electric components in the electric junction box usually requires an opposing function of firmly fixing the electric components such as the relay switch, and easily detaching the electric components if necessary.

A conventional jig for extracting electric parts will be described below by taking a relay box as an example. As shown in FIG. 6, a relay switch socket 33 is provided on a chassis 32 constituting the relay box 31. A frame 3 for protecting the relay switch 35 is provided around each socket 33.
4 is provided, and the relay switch 35 is inserted into the internal space. In addition, flexible locking claws 36a and 36b are formed on the side plate of the frame body 34.

[0004] When the relay switch 35 is mounted on the relay box 31, the relay switch 35 is inserted through the upper opening of the frame 34 and is pushed in as it is. At this time, since the upper surfaces of the locking claws 36a and 36b are formed as tapered surfaces, they are opened outward by pushing the relay switch 35, and when the relay switch 35 is inserted to a predetermined position, the relay returns to the original shape and the relay is returned. Switch 35
Will be locked. Therefore, the relay switch 3
The connection terminal 35 a provided at the lower end of the socket 5 is electrically connected to the socket 33, and the relay switch 35 is prevented from coming off.

[0005]

However, when removing the relay switch 35, the relay box 31 raises the relay switch 35 upward.
Unlocking and lifting of the locking claws 36a and 36b must be performed at the same time.
Therefore, conventionally, the pliers or the like were removed after being clamped. However, depending on the on-board condition of the relay box 31, there is no space around the relay box 31 and the pliers or the like cannot be used. There is a problem that causes the deterioration of the performance.

In order to solve the above problems, the inventor of the present application has proposed a drawing jig as shown in FIGS. 7 and 8 prior to the present invention. This extraction jig 41
As shown in FIG. 7, a jig main body 42 formed integrally with a synthetic resin and having a vertically long shape, and a large-diameter opening 43 formed at the upper end of the jig main body 42 are opposed to each other. A pair of grooves 44a, 44b formed on the side surface, and mounting protrusions 45a, 45 formed on the lower end of the inner surface of the frame 42.
b, 45c and 45d.

As shown in FIG. 8, when the relay switch 35 is mounted on the relay box, the relay switch 35 is first inserted into the frame 34 so that the connection terminal 35a provided at the lower end of the relay switch 35 is electrically connected to the socket 33. Connected. When the relay switch 35 is to be removed, the upper end of the removal jig 41 is inserted into the gap between the frame body 34 and the relay switch 35 while applying a pressing force F inward, and is removed to the lower end of the relay switch 35. The mounting projections 45a, 45b, 45c of the jig 41,
Push in until 45d is locked. Then, by pulling the extraction jig 41 upward, the relay switch 3
5, the relay switch 35 can be easily pulled out of the relay box 31 without using a tool such as pliers, and the workability during maintenance is improved.

However, in the extraction jig 41, it is necessary to provide a gap for inserting the extraction jig 41 into the frame 34. By forming this gap, the side surface of the extraction jig 41 corresponding to the locking claws 36a, 36b is pressed by the locking claws 36a, 36b.
There is no pressing of the side surface on which the a and 44b are formed, and there is a problem that rattling occurs in this direction. In addition, when a new relay switch is inserted after the relay switch 35 is once extracted, there is a problem that the workability is deteriorated because the gap exists.

Although the extraction of the relay switch 35, which is an example of an electric component, has been described above, there is a "fuse extraction tool" disclosed by the applicant of the present application in Japanese Utility Model Laid-Open No. 5-17904. This fuse extraction tool is to prevent the blade type fuse from jumping out of the extraction tool when extracting it.
Even if the configuration is used for extracting the relay switch 35, the above problem cannot be solved.

An object of the present invention is to provide a jig for extracting an electric component and a method for extracting the electric component, which can easily remove the electric component inserted into the electric device and can surely prevent the detachment of the electric component. It is in.
