Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a fuse holder.

(B) Conventional Technology FIG. 4 is a perspective view showing a conventional fuse holder.

This fuse holder has a fuse housing empty space 51
Is a case body 52 with an upper opening and a bottom, and
The terminal portions 53, 53 to which the electrodes 41, 41a of the fuse 4 contact
The external connection terminal portions 54, 54 electrically connected to the terminal portions 53, 53 are provided on the outside of the accommodation vacant chamber 51.

The fuse 4 is housed in the housing vacant chamber 51 of the case body 52,
The electrodes 41, 41a at both ends are in contact with the terminal portions 53, 53 of the accommodation chamber 51.

(C) Problem to be Solved by the Invention The fuse accommodating chamber of the conventional fuse holder (case body) described above is set to a space approximately equal to the size of the fuse. This ensures the vibration resistance of the fuse housed in the housing vacant room.

However, the size of the accommodation vacancy is the size of the fuse,
Since it is almost the same, it is difficult to insert a finger into the gap between the fuse and the accommodation space. For this reason, it is difficult to take out the fuse from the accommodation space with fingers. If the fuse is forcibly taken out with the fingers, there is a risk that the fingers may be erroneously located near the fuse (fuse holder) during the taking-out work, for example, a bare electric circuit may be touched. On the other hand, as shown in FIG. 4, there is a tweezer-like fuse pull-out tool 6 that can be inserted into the gap between the fuse and the accommodation space. The use of the fuse pulling tool 6 eliminates the inconvenience and the risk of the above-mentioned hand and finger taking-out operation. However, in this case, since a special fuse pulling tool is required, there is a disadvantage in that the fuse pulling tool must be always provided.

An object of the present invention is to solve the above problems and to provide a fuse holder that is easy and safe for fuse replacement work.

(D) Means and Actions for Solving the Problem In order to achieve this object, the fuse holder of the present invention has the following configuration.

The fuse holder is detachably engaged with a case main body with an upper opening and a bottom, which has one end side of the peripheral wall opened and which has a pair of terminals inside, and an engagement groove formed on the inner surface of the other end side of the case main body. A cover body having an engaging piece on the upper surface and a fuse holding portion on the lower surface, and a pivotally rotatably mounted bearing on one end side opening of the case body. It is characterized by comprising a fuse take-out operation section having a lock section that engages with the locking piece.

In the fuse holder having such a configuration, the fuse removal operation section has a cross-section “L” including, for example, a horizontal plate portion parallel to the bottom surface of the case body and a vertical plate portion rising vertically from the end of the horizontal plate portion. It is formed in the shape of a letter "", and is formed by providing an inward lock portion (protruding piece portion) on the upper portion of the vertical plate portion. In the normal state, in the rotatable fuse taking-out operation portion, the vertical plate portion is held substantially vertically to the bottom surface of the case body. In this state, in the cover body that holds the fuse in the sandwiched portion, the engagement piece at the other end fits into the engagement groove of the case body, and the one end side engagement piece is the lower surface of the lock portion (protruding piece portion). The upper opening surface of the case body is closed by the cover body by being caught and locked by the fuse, and the fuse is housed in the housing space of the case body. In this stored state, both electrodes of the fuse are in contact with both terminal portions of the case body. At the time of taking out the fuse, the fuse taking-out operation portion is rotated outward. That is, by pushing the upper end portion of the vertical plate portion outward of the case main body, the fuse removal operation portion is rotated outward. As a result, the engagement between the other end side locking piece of the cover body and the lock portion (protruding piece portion) located above the locking piece is released. At the same time, the fuse (the cover body that holds the fuse) is pushed upward by the tilting of the horizontal plate. Here, by grasping the photographing part of the cover body with fingers and disengaging the engagement piece of the cover body from the engagement groove of the case body, the cover body with the fuse sandwiched therein can be taken out.

Thus, the fuse can be taken out extremely simply by simply rotating the fuse taking-out operation portion. Therefore, operability and safety of fuse replacement can be realized.

(E) Embodiment FIG. 1 is a sectional view showing a fuse holder according to the present invention.

The fuse holder includes a case body 1, a cover body 2 that closes the upper opening surface of the case body 1, and a fuse take-out operation section 3 that is rotatably attached to the case body 1.

The case body 1 has a rectangular parallelepiped shape and has an opening at one end side 1b of the peripheral wall 1a, a terminal portion 13 is erected on the inner surface of this one end side, and a terminal portion 11 is provided on the other end side inner surface (end wall inner surface) 1c. It is formed with an open bottom. An engagement groove 12 is formed in the inner surface 1c of the other end of the case body 1 so that an engagement piece 21 of the cover body 2 described later can be detachably engaged.

As shown in the perspective view of FIG. 3, the cover body 2 is a flat plate having a size corresponding to the upper opening surface of the case body 1, and has a photographing portion 22 projectingly provided on the upper surface thereof and a fuse sandwiched on the lower surface thereof. Dress
23 are projected. The fuse 4 is the fuse holding portion.
Removably attached to 23. An engaging piece 21 corresponding to the engaging groove 12 of the case body 1 is provided on one end side of the cover body 2.
Is protruding.

The fuse take-out operation portion 3 is provided on the bottom surface of the case body 1 with a horizontal plate portion 34 formed of two horizontal plates extending in parallel from both ends of the shaft 33, and an end portion of the horizontal plate portion 34. It is formed in a side "L" shape consisting of a vertical piece 35 which stands up vertically. An inward lock portion (protruding piece portion) 32 is provided on the upper portion of the vertical plate portion 35. The fuse take-out operation portion 3 is rotatably supported by the opening of the other end side 1b of the case body 1. That is, the pivots 33 projecting from both sides of the intersection of the horizontal plate portion 34 and the vertical plate portion 35 are mounted on the both side walls 1a of the case body 1 by bearing.

In the fuse holder having such a configuration, in the normal state, in the rotatable fuse taking-out operation portion 3, the vertical plate portion 35 is held in a state substantially vertical to the bottom surface of the case body 1. In this state, in the cover body 2 that holds the fuse 4 in the sandwiching portion 23, the one end side engaging piece 21 has the case body 1
