Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fuse holder, particularly to an improvement in its locking mechanism.

As shown in Fig. 1, a conventional fuse holder consists of two semi-cylindrical holder half members 1 and 2 connected by a thin hinge part 3 integrally molded with resin so as to be openable and closable. , knobs 4 and 5 are attached to approximately the middle of the open side edges 1a and 2a of each of the holder half members 1 and 2 so as to intersect with each other; Female locks 6, 7 are formed on both sides of the holder 4, and male locks 8, 9 to be engaged with the female locks 6, 7 are formed on both sides of the knob 5 on the open end edge 2a of the other holder half member 2. When the holder halves 1 and 2 are closed, the female lock 6 or 7 and the male lock 8 or 9 are engaged to lock the holder, as shown in FIG.

However, when an attempt is made to open the holder as described above, the female lock 6, which is close to the knob 4, causes the opening side edge 1a of the holder half member 1 to move slightly outward when the knob 4 is pressed, as shown by the broken line in FIG. The male lock 9, which is close to the knob 5, bends outward when the knob 5 is pressed and bites into the female lock 7, making it difficult to release the lock.
In the end, only female lock 6 and male lock 8 were released, resulting in the drawback that the holder was difficult to open.

The present invention was devised to eliminate the above-mentioned drawbacks of the conventional fuse holder, and its purpose is to provide a fuse holder that can release the right and left locks at the same time and that allows the holder to be opened easily. be.

An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 4 and 5, reference numerals 11 and 12 are holder half members, which are connected by a hinge portion 13 so as to be openable and closable. The holder half members 11 and 12 are closed in a cylindrical shape and are adapted to accommodate a fuse (not shown) inside. Knobs 14, 15 are attached to approximately the middle of the open side edges 11a, 12a of each holder half member 11, 12 so as to protrude outward at alternate positions, and each of the knobs 14, 15 closes the holder. Time is beginning to intersect with each other.

A female lock 1 is provided at the open end edges 11a, 12a of the knobs 14, 15 close to the outside in the axial direction.
6 and 17 are formed, and male locks 18 and 19 to be engaged with the respective female locks 16 and 17 are formed at the corresponding opening side edge portions (areas far away from the knobs 14 and 15). ing.

3, the bending positions of the holder half members 11 and 12 are shifted, and the female locks 16 and 17 and the male locks 18 and
This prevents variation in the engagement relationship between the parts 19 and 19.

When closed as described above and shown in FIG. 7, each female lock 16, 17 is positively engaged with a male lock 18, 19 to safely accommodate the fuse. and,
When opening the fuse holder, push the knobs 14 and 15 in the direction of the arrow with your fingers as if opening a loose seal case or a seal case, and the female locks 16 and 17 formed near the knobs 14 and 15 will bend outward. At the same time, it is removed from the Oslocks 18 and 19, and the holder can be fully opened with one touch.

As described above, the present invention consists of two holder half members made of synthetic resin that can be opened and closed by hinges, and knobs are attached alternately to approximately the middle of the open side edge of each holder half member, and each A female lock is formed on the outer side in the axial direction opposite to the mutually intersecting sides of the knob, close to the knob and at the open end edge of the holder half member, and a female lock is formed at the corresponding open end edge of the holder half member. Since the fuse holder is formed with a male lock that engages with the female lock, when the fuse holder is opened, as the knobs provided alternately are pressed in the direction of disassembly, each female lock portion located close to the knob is released. Due to the flexibility of the synthetic resin material, it is reliably driven in the direction away from the male lock, allowing two sets of locks to be released at the same time, which has the practical benefit of allowing the fuse holder to be opened easily and quickly.

Claims (1)

[Scope of utility model registration request] The two holder half members are made of synthetic resin and can be opened and closed by hinges, and knobs are provided alternately approximately in the middle of the open edge of each holder half member, and the knobs are arranged so that the knobs intersect each other and the opposite sides of the half members are attached to each other. A female lock is formed at the open end of the holder half member on the outside in the axial direction on the opposite side, close to the knob, and a male lock that engages with the female lock is formed at the corresponding open end of the holder half member. A fuse holder characterized by the fact that it is formed.
