Description

[Detailed Description of the Invention] The present invention relates to an improvement of a fuse holder into which a cylindrical fuse is inserted and held.

Generally, a fuse holder consists of an insulating base and a pair of conductive holder metal fittings that are spaced apart from each other and have elastic holding pieces into which the fuse terminals engage. In the conventional technology, the holder metal fittings are fixed to the insulating base by rivets or screws, which requires a troublesome tacking operation, resulting in low workability, and a pair of holder metal fittings are not perfectly aligned. The problem was that it was difficult to insert and remove the fuse, and it also caused poor contact with the fuse.

The purpose of the present invention is to facilitate the installation work of the holder metal fittings, to enable smooth insertion and removal of the fuses, and to automatically insert and remove the fuses even if a pair of holder metal fittings are not aligned. To provide a fuse holder that is aligned and does not cause poor contact.

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a fuse holder 10 according to the present invention,
This fuse holder 10 includes an insulating base 12 and 1
It consists of a pair of conductive holder fittings 14, 14'. As shown in FIG. 2, each of the holder metal fittings 14, 14' includes a board 18 having a terminal 16 to which a lead wire (not shown) is connected by soldering or the like, and a terminal of the fuse 1 extending upright from both edges of this board. A pair of elastic holding pieces 2 in which 2 and 2' engage elastically.
It consists of 0. The substrate 18 has an elastic holding piece 2
both sides protruding pieces 22 extending horizontally from both sides on the outside of 0;
22', and an inner end protrusion 24 at the inner end.
The holder metal fittings 14, 14' are installed by being inserted horizontally into grooves 26, 26' provided at both ends of the insulating base 12. The grooves 26, 26' have an opening 28 at the center from which the elastic holding pieces 20, 20 protrude, and lateral grooves 30, 3 into which the protruding pieces 22, 22' on both sides engage.
0' and an end groove portion 32 into which the inner end projecting piece 24 engages. Therefore, the holder metal fittings 14, 14' are prevented from coming off upward by the upper walls of the lateral groove portions 30, 30' and the end groove portion 32.

Anti-slip means 34 are provided between the holder fittings 14, 14' and the groove 26, and in the illustrated embodiment the anti-slip means are arranged on the base plate 18, of the holder fittings 14, 14'.
It consists of a punching pawl 36 formed by punching out the groove 18' and engaging the bottom surface of the groove 26, 26' in a direction opposite to the engaging direction. Therefore, as will be explained later, this anti-slip means 34 can allow displacement for alignment of the holder fittings 14, 14'.

The cylindrical fuse 1 has terminals 2, 2' attached to elastic holding pieces 20, 20 of a pair of holder fittings 14, 14'.
In this case, the holder metal fitting 1
4 and 14' are inserted into the groove 26 with some play in the horizontal direction, so that they are automatically aligned by the fuse 1 and no contact failure occurs.

According to the present invention, as described above, the pair of holder metal fittings can be installed by inserting them into the grooves of the insulating base, making it easy to assemble the fuse holder and improving work efficiency.
In addition, since the pair of holder metal fittings have horizontal play and are automatically aligned when the fuse is inserted, there is no possibility of poor contact, and the fitting and removal can be carried out smoothly, making it easy to handle. Further, since the anti-slip means prevents the holder metal fittings from coming off while allowing displacement for alignment of the holder metal fittings, the holder metal fittings do not escape from the insulating base.
