Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a holding structure for storing spare parts of blade-type fuses used in various electrical components.

[Conventional technology]

Conventionally, a holding structure for storing a spare part of a blade-type fuse in a box is known as shown in the sectional view in FIG. 6 (Japanese Utility Model Publication No. 57-190641). This holding structure includes an elastic piece f formed on one side e of the insertion hole d into which the housing portion b of the blade-type fuse a is inserted;
The elastic piece f holds the terminal c of the fuse a which is inserted into the fuse and protrudes downward.

However, in such a holding structure, since the fuse a is held only by the elastic piece f, it is easy for the fuse a to be inserted incompletely, and the fuse box g containing spare parts cannot be mounted on a vehicle or the like. In some cases, the fuse a may be damaged due to vibration or shock.
There is a disadvantage that the fuse box g easily separates from the insertion hole d.

[Problem that the invention attempts to solve]

The present invention was developed by focusing on the drawbacks of conventional holding structures for blade-type fuses, and aims to provide a holding structure that does not easily detach from the insertion part due to vibrations, shocks, etc. do.

[Means for solving problems]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings, which illustrate embodiments.

Fig. 1 is a longitudinal sectional view of the preliminary fuse holding structure of the present invention, Fig. 2 is a perspective view of the upper part of the holding structure,
FIG. 3 shows a plan view of the holding structure, FIG. 4 shows a vertical cross-sectional view of a blade-type spare fuse inserted into the holding structure, and FIG. 5 shows a front view of the blade-type fuse.

In these figures, the spare fuse holding structure A of the present invention is formed in one part of the fuse box, and includes longitudinal side walls 1a, 1b and left and right side walls 1c, 1d perpendicular to the side walls 1a, 1b.
An opening 2 with a rectangular cross-section into which a blade-shaped spare fuse (hereinafter simply referred to as fuse) B is inserted is formed in the upper part which is partitioned into a substantially rectangular parallelepiped shape, and an opening 2 with a rectangular cross section is formed on one side wall 1a side in the longitudinal direction. A beam-like elastic pressing arm 3 is formed which partially bulges inward, and
A locking arm 4 is formed integrally with the side wall 1b at a portion facing the pressing arm 3, and projects from its upper edge and has a locking protrusion 4a at its upper end.

Therefore, the beam-shaped elastic pressing arm 3 is formed so that its central portion slightly bulges out into the opening 2 in the form of a beam supported from the left and right side walls 1c, 1d, and the bulged center A guide plate 5 whose plate surface 5a is slightly inclined outwardly from above is formed integrally with the pressing arm 3.

Further, on the inner surface of the longitudinal side wall 1b facing the pressing arm 3, there is an inclined surface 6 in the direction in which the opening 2 expands upward.
A receiving plate 6 provided with a is attached. Furthermore, side wall 1
A pair of plate-shaped fuse stoppers 7 are installed at the bottom of b.
are protrudingly provided at positions corresponding to the tips of the pair of terminals 8 of the fuse B inserted into the opening 2. or,
The fuse stopper 7 may be provided to protrude from the side wall 1a or 1b so as to support the housing portion 9 of the fuse B.

In addition, in the above, the side wall 1a is omitted and both ends of the elastic pressing arm 3 are connected to the side walls 1c and 1d to form the side wall 1a.
In some cases, the locking arm 4 also serves as the side wall 1b.

The holding structure A for the fuse B having the above structure is molded from a relatively hard and elastic plastic material, and a plurality of them can be disposed in the box D.

[Effect]

To insert the fuse B into the holding structure A of the present invention, insert the fuse B into the opening 2 from the terminal 8 side along the slope 6a of the guide plate 5 and the receiving plate 6. At that time, the pressing arm 3 is pressed against the side wall 1a due to its elasticity.
The fuse B is bent to the side to facilitate the insertion of the fuse B, and is inserted between the receiving plate 6 and the pressing arm 3.
The housing portion 9 of is pressed and held. In addition, the fuse B can be connected to the tip of the terminal 8 or the housing part 9.
When the lower edge of the locking arm 4 contacts the stopper 7, the gripping portion 10 engages with the lower surface of the locking protrusion 4a of the locking arm 4, and the fuse B is closed as shown in FIG. It is completely inserted into the opening 2.

On the other hand, when removing the fuse B inserted into the opening 2, by pulling the grip part 10 in the direction of the arrow in FIG. The grip part 10 can be easily removed by removing it from the holder.

[Effect of idea]

Since the spare fuse holding structure of the present invention has the configuration and operation described in detail above, it is easy to insert the fuse into the fuse box, and the inserted fuse has a housing part with a beam shape. It is held by the elastic pressing arm, the terminal part is held by the stopper 7, and the grip part is locked by the locking protrusion of the locking arm, so even if vibration or impact is applied to the box, the fuse will not be discharged from the box. Detachment is almost completely prevented.
