Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fuse box cover for protecting a fuse housed in a fuse box.

[0002]

[Prior art]

 Conventionally, this type of fuse box cover has been designed so that it can be opened / closed via a hinge to the fuse box body that houses the fuse, or can be removed from the box body.

In addition, in a cover that can be removed from the box body, a fuse removing means for removing the accommodated fuse may be integrally provided at a corner of the cover, and the fuse may be removed from the box body. It is used when pulling out.

[0004]

[Problems to be solved by the device]

 However, the conventional example in which the fuse removing means described above is provided requires a space because the fuse removing means is provided independently.

An object of the present invention is to solve the above-mentioned problems, and since the locking member used for locking the fuse box body is also used for removing the fuse, it does not require a space and is easy to handle. To provide a box cover.

[0006]

[Means for Solving the Problems]

 A fuse box cover according to the present invention for achieving the above object is a cover which is detachably attached to a fuse box body accommodating a gate type fuse, and the fuse box cover is provided on a side surface of the fuse box cover. A locking member for integrally engaging with the locking projection of the main body is integrally provided, and a claw portion for engaging with the groove of the fuse and pulling out the fuse is provided at the tip of the locking member. Is.

[0007]

[Action]

 In the fuse box cover having the above-mentioned structure, when the cover is attached to the box body, the locking member easily acts on the locking protrusion of the box, and further, the locking member does not fuse with the fuse. Used when pulling out from the box.

[0008]

【Example】

 The present invention will be described in detail with reference to the illustrated embodiment. 1 is a cross-sectional view of the box body 1 and the cover 2, and FIG. 2 is a plan view of the cover 2. A plurality of receiving terminals 3 are vertically and horizontally housed inside a box body 1 made of a synthetic resin material, and these receiving terminals 3 have gates as shown in the front view (a) and side view (b) of FIG. The mold fuse 4 is inserted. A hinge projection 5 is provided on one side surface of the box body 1, and two claw-shaped locking projections 6 are provided on the other side surface of the box body 1 at predetermined intervals. The upper side 6a of the protrusion 6 is inclined downward to the right with respect to the side surface of the box body 1, and the lower side 6b is formed as a vertical surface.

On the other hand, a cover 2 made of a synthetic resin material is detachably attached to the box body 1, and one side surface of the cover 2 engages with a protrusion 5 of the box body 1 and has a rod-shaped hinge locking portion 7 for engaging with the hinge. Is provided. A lock member 9 is provided on the other side surface of the cover 2. The lock member 9 has a substantially rectangular tube shape, the upper end of which is substantially coincident with the upper end of the cover 2, and the lower end of which is the cover of the box body 1. It extends further downward from the lower end of 2. Further, an engaging hole 10 that engages with the locking projection 6 of the box body 1 is provided inside the locking member 9, and the tip of the locking member 9 is provided with the fuse 4 when the fuse 4 is pulled out. Two locking claws 11 that engage with the formed groove 4a are formed to face each other. The lower side of the locking claws 11 is an inclined surface and the upper side is a vertical surface. Further, a notch 12 is provided between the lock member 9 and the cover 2 so that the lock member 9 can be tilted with respect to the cover member 2.

With this configuration, when the cover 2 is attached to the box body 1, the hinge locking portion 7 of the cover 2 is fitted into the hinge protrusion 5 of the box body 1, and the cover 2 is attached to the box. As shown in FIG. 4, the lock member 9 on the other side is rotatable with respect to the main body 1, and the lower end of the lock member 9 is bent outward by pushing the upper end inward with a finger, and the cover 2 is moved downward. The lock projection 6 is fitted into the engagement hole 10 by rotating the lock projection 6. At this time, since the upper side 6a of the projection 6 is inclined, the locking member 9 easily slides on the upper side 6a and engages with the engaging hole 10, and thereafter the lower side 6b is a vertical surface. As shown in FIG. 1, the locked state is reliably retained.

When removing the cover 2 from the box body 1, as shown in FIG. 5, the upper end of the locking member 9 is pushed inward to bend the lower part of the locking member 9 outward to lock it. The engagement between the protrusion 6 and the engagement hole 10 is released, and the cover 2 is pulled up.

On the other hand, when pulling out the fuse 4 from the box body 1, as shown in FIG. 6, the locking claw 11 of the locking member 9 of the removed cover 2 is engaged with the groove 14 a of the fuse 4. And pull it out. At this time, since the lower surface of the locking claw 11 is inclined, the space between the locking claws 11 easily enters and engages with the groove 4a of the fuse 4, and thereafter the upper surface is vertical, so that the engagement state is maintained. Can be pulled out easily because it is securely held.

In this case, since the locking member 9 extends downwardly from the cover 2 for a sufficiently long time, even if the fuses 4 are densely loaded, they can be easily engaged with each other.

FIG. 7 is a cross-sectional view of the second embodiment, in which a cover 21 is provided with a rectangular tubular locking member 22 of the same height, and inside the locking member 22, the first locking member 22 is provided. A locking claw 23 for pulling out the fuse similar to that of the embodiment is provided. Further, the elastic arm 25 having the projection 25a is integrally formed on the side surface of the box body 24, and the cover 21 is locked to the box body 24 by engaging the projection 25a with the locking claw 23. Has become.

Also in this case, the lock member 22 has a lock function with respect to the box body 24, and the locking claw 23 engages with the groove 4a of the fuse 4 and is used as a fuse removing means.

[0016]

[Effect of device]

 As described above, in the fuse box cover according to the present invention, the cover is provided with the locking member so that the locking can be easily performed, and the claw portion at the tip of the locking member is easily fitted to the fuse. The fuse can be pulled out.
