Description

[Detailed Description of the Invention] The present invention relates to a storage structure for a blade-type fuse attachment/detachment tool.

As shown in FIG. 1, a blade-type fuse 1 is constructed by arranging thin metal conductor blade pieces 2, 2 in parallel, and connecting the blade pieces 2, 2 with a fuse wire 3. , the upper part of 2 is molded with insulating synthetic resin,
A head 4 is formed at the top that extends to the sides.

As shown in FIG.
It is guided by a guide piece 6 erected on the upper surface.

The guide piece 6 is erected at the peripheral corner of the insertion hole 7 along the shape of the blade-type fuse 1 which is provided in parallel on the upper surface of the fuse block main body 5, and a blade is provided at the inner bottom of the insertion hole 7. A female terminal (not shown) is arranged to receive the blade pieces 2, 2 of the fuse 1.

By the way, in order to make the contact state of the blade type fuse 1 strong, the blade piece 2 is firmly clamped by the female type terminal, and therefore it is often difficult to remove the blade type fuse 1 by picking it with your fingertips. A clip is used as a fuse removal tool for easy removal.

The present invention allows the fuse block main body 5 and the fuse block cover 6 to be easily attached to each other using a clip as a fuse extraction tool.
This invention relates to a storage structure for a blade-type fuse 1 attachment/detachment tool that can be taken out from four housing parts 8, 8 provided in the housing and quickly stored and held after use.

Hereinafter, the present invention will be described in detail based on specific embodiments shown in the accompanying drawings.

The clip 14 is made of resin, as shown in FIGS. 3 and 4, and consists of a pair of legs 11.12, the upper parts of which are connected by a flexible thin plate-like connecting piece 13.13. There is.

Locking claws 12, 12 are molded at the tips of the lower leg parts 15.15, and by pinching the side surfaces 11.11 of the upper leg parts with fingers, the connecting pieces 13.13 are bent and the locking pieces 12, 12 are bent. 12 has a lip structure that opens.

When using this clip 14, pinch the upper side surface 11.11 of the clip, hold the crown under the head of the blade-type fuse 1 with the lower legs 15.15 opened, and then open the legs. is closed, the locking claws 12, 12 are engaged with the head locking piece 4, and pulled out in this state to remove the blade type fuse fitted into the insertion hole 7 of the fuse block.

After the blade-type fuse 1 is removed, the clip 14 is attached to the head-locking piece of the blade-type fuse 1 by pinching the upper side surface 11.11 of the clip again and opening the locking claws 12, 12 of the open leg part. 4, or remove the clip 14 from the blade-type fuse 1 while still engaged.
It is possible to release the bond by sliding it in the longitudinal direction.

After use, the clip 14 should be used to prevent it from being lost.
Again, it is necessary to store it in an appropriate location on the fuse box main body 5 or the fuse box cover 16 in order to use it quickly next time.

That is, as shown in FIGS. 2 and 5, the fuse box body 5 or the box cover 16 is provided with an appropriate distance of m from the opening legs of the clip 14 so that the opening legs of the clip 14 can be opened. A housing recess 8.8 is provided, and the housing recess 8,8 has a protruding upper side surface 11.11 that prevents mutual interference between the fuse box main body 5 and the fuse box case 16 when storing the clip 14, and makes it easy to pick. A locking piece 10 that engages with a locking pawl at the tip of the open leg part is provided at an appropriate depth and position to ensure the desired amount.

The retaining piece 10 has an inclined surface or a curved surface,
By simply pushing the clip 14, the clip 14 is easily engaged with the locking pawl 12 after the legs are opened.

Further, the locking piece 10 is integrally molded with a guide piece 9 that has a thickness that can be inserted between the pair of legs and extends to the opening end line of the accommodation recess when the clip is inserted.

The clip 14 is inserted into the accommodation recess 8 of the fuse box main body 5.
To store the clip 14, the guide piece 9 is first inserted between the legs of the clip 14, and the guide piece 9 is pushed in while being guided, and the clip 14 engages with the engaging piece 10 with one touch to complete the storage.

Conversely, the operation of removing the clip 14 from the accommodation recess 8 of the fuse box main body 5 is performed using the upper side surface 11, 1.1 of the clip.
Pinch with your fingers and open the leg part to separate the locking piece 10 and the locking claw 12.
, 12 and pull it out.

The storage location of the clip 14 is not limited to the storage recess 8 of the fuse box body 5, but also the fuse box body cover 15.
The accommodation recesses 8, 8 can be provided by effectively utilizing the appropriate space.

In this way, the operation of taking out and storing the clip 14 can be performed with a single touch, and even when the blade type fuse 1 is removed, there is no need to change the clip.

Furthermore, if the guide piece 9 is formed as in the embodiment, the direction of the claw at the tip of the clip and the direction of the locking piece 10 can be automatically determined when the clip is housed, and the clip will not get stuck in the housed state.

The present invention is designed to accommodate a clip-shaped fuse attachment/detachment tool that consists of both left and right legs, has a locking claw at the lower tip and can be opened, and is designed to be used in the fuse block itself or its case. A rectangular accommodation hole capable of fully accommodating the open leg portion of the fuse is provided in a part of the fuse, and
When stored, the fuse attachment/detachment tool can be easily taken out or stored by providing a partition wall with a locking piece formed at the bottom that guides the open leg of the fuse attachment/detachment tool and engages with a locking claw. Because of the storage structure of the fuse removal/detachment tool, removal and storage of the extraction tool can be performed quickly and easily with one touch, and there is no need to change the extraction tool when removing a blade-type fuse. When the extraction tool is stored, it will not be lost due to its engagement with the locking piece.
