Description

[Detailed description of the invention] The present invention relates to a fuse protector, and the present invention relates to a fuse holder, which includes a fuse holding part for holding a fuse, and a hooking part with a box by bending the tip of the fuse holding part outward. and,
A box in which an inwardly protruding protrusion and an outwardly protruding protrusion that engage the fuse holder or a fuse attached to the fuse holder are formed on a side wall of the case, and in which the protrusions are arranged. A slit is formed on both sides of the protrusion on the side wall, and the inward protrusion is engaged with the fuse holder or a fuse attached to the fuse holder, and the hook of the fuse holder is engaged. By forming an insulating box that covers the fuse holder and the fuse attached to the fuse holder, the fuse holder is configured to have an internal shape that is similar to the fuse holder, and a mounting hole for holding the box is formed on the board. There is no need to create a shape, and there are no restrictions on pattern design on the board.
Further, it is an object of the present invention to provide a fuse protector that facilitates the work of attaching a fuse to a fuse holder, can firmly hold the fuse in the fuse holder, and does not shake when holding the fuse.

Conventionally, as shown in FIG. 1, in the fuse protector, a fuse holder 3 having an arcuate tip is fixed to a board 2 at a predetermined position on which a fuse 1 is attached by soldering or the like, and a fuse holder 3 is fixed at a predetermined position on the board 2. The hole 4 is shaped, the claw 5 of a box 6 having a claw 5 is inserted into the hole 4, the box is attached to the board, and the fuse is protected by the box.

However, with this type of fuse protector, the board must have a hole for hanging the case, and the size of this hole must be larger than the claw on the case. As a result, relatively large holes must be formed in the substrate, which places greater restrictions on pattern design on the substrate.

This restriction is not limited only to the size of the hole, but since the claws are hooked around the hole, the restriction is greater than the size of the hole.

Further, since the claws protrude from the substrate, this restriction is not only a two-dimensional restriction but also a three-dimensional restriction.

Furthermore, in this fuse protector, there is no relationship between the fuse holder, etc. and the box, so the box, etc. is relatively loose, and the protection of the fuse, etc. is not perfect.

Furthermore, since the tip of the fuse holder faces inward, it is troublesome to install the fuse.

The present invention eliminates the above drawbacks, and examples thereof will be described below.

FIG. 2 is a longitudinal cross-sectional view of the fuse protector according to the present invention, FIG. 3 is a cross-sectional view, and FIG. 4 is a cross-sectional view of the fuse protector box.

In the figure, 10 is a board, and a fuse holder 11 made of an elastic material is fixed to a predetermined position of this board 10 by soldering or the like.

This fuse holder 11 has a central portion 11' shaped into a substantially arc shape to hold the fuse 12, and a tip portion 11'' bent into a substantially doglegged shape, with the tip facing outward. is prominent.

Reference numeral 13 denotes a box made of insulating plastic and having a substantially trapezoidal cross section that covers the fuse holder 11 and the fuse 12, and the ends of the box 13 are provided with protruding claws on the inside and outside of the box. 14 is in full form.

The wall 13 of the box 13 on which the claw 14 is shaped
' has slits 15 formed on both sides of the claw 14,
Resilience is imparted to the claw 14 portion.

This box 13 is not only larger than the size of the fuse 12, but also has a larger size than the leading edge 11 of the fuse holder 11.
The fuse holder and the box are sized so that the fuse holder and the box come into contact with the inner wall of the box 13.

In the fuse protector configured as described above, the fuse is first held in the fuse holder, and since the tip of the fuse holder faces outward, the operation of inserting and holding the fuse is extremely easy.

Moreover, since the tip of the fuse holder comes into contact with the inner wall of the casing that covers the fuse, the fuse holder receives internal force, and the fuse is firmly held and does not wobble no matter what external force is applied.

Furthermore, since the box is also supported by the tip of the fuse holder, the box itself will not wobble.

Furthermore, since the box has a generally trapezoidal cross-section with the opening end wider, the fuse holder does not get in the way at first when installing the box, and the inner wall of the box gradually moves the fuse holder towards the fuse holder. This means that an inward force is applied, making the fuse less likely to be damaged.

Then, hook the claw of the box onto the top surface of the fuse, for example,
Fix the box.

When latching and fixing this case, the claw part is designed to have elasticity, so simply pull the claw part outward and then release it, and the claw can be latched onto the top surface of the fuse. can be done, and the work is extremely simple.

As described above, the fuse protector according to the present invention includes a fuse holder for holding a fuse, a fuse holder in which a tip of the fuse holder is bent outward to form a hook part for a box, and a fuse holder for holding a fuse. An inwardly protruding protrusion and an outwardly protruding protrusion that engage the fuse holder or the fuse attached to the fuse holder are formed on the side wall of the box,
and a slit is formed on both sides of the protrusion of the side wall of the box where the strip is formed, and the inwardly protruding protrusion is latched to the fuse holder or a fuse attached to the fuse holder. and an insulating box that covers the fuse holder and the fuse attached to the fuse holder, which is configured to have an internal shape that allows the hooking part of the fuse holder to be hooked. It is no longer necessary to form mounting holes, etc., on the board for holding, there is no restriction on the pattern design on the board, and since the box and fuse holder are mutually supported, it is easy to There is no rattling, and the fuse is held securely.Also, the fuse is held not only by the fuse holder but also indirectly by the box, so the fuse is perfectly held, and no matter what direction it is turned, No matter how much external force is applied, the fuse will not fall off, and the installation of the fuse and the case is easy, and since the fuse is covered by the case, there is no risk of getting an electric shock by accidentally touching the fuse. It has features such as being able to prevent accidents.
