Description

[Detailed description of the invention] This invention relates to a terminal block with a fuse.

When connecting a soldering terminal section to a fuse holder section that electrically and mechanically connects and holds a fuse, it is necessary to provide a fixing section for the fuse holder section and a fixing section for the soldering terminal section on the body of the terminal block. As a result, the structure of the terminal block had the disadvantage of increasing its size.

Therefore, an object of this invention is to provide a terminal block with a fuse that has a simple structure and can be miniaturized.

An embodiment of this invention is shown in FIGS. 1 to 5. That is, this terminal block with a fuse consists of a body 1, a terminal 2, and a fuse 3. First, the body 1 has two terminal accommodating grooves 4 and 5, and a fuse accommodating groove 6 that is continuous with one of the terminal accommodating grooves 5. Both ends of the terminal accommodating grooves 4 and 5 are open, and one end of the terminal accommodating grooves 4 and 5 is open. Support parts 7 and 8 are provided near the part,
Attachment holes 9 are formed in the support parts 7 and 8, and a partition part 10 is provided protruding from the terminal receiving groove 5 next to the support part 8. The fuse housing groove 6 also has one end wall in the longitudinal direction serving as the side wall 1a of the body 1, and the other end wall is formed by a positioning rib 11 set upright in the fuse housing groove 6. An insertion slit 12 is formed. There are three terminals 2,
The first terminal 13 is a rectangular terminal plate, and has a terminal screw threading slit 14 that opens laterally at one end, and a mounting hole 15 at the center thereof. The first terminal 13 is fitted into the terminal accommodating groove 4, placed on the support portion 7, and mounted by passing the driving stud 16 through the mounting hole 15 and driving it into the mounting hole 9. In addition, before installation, install the terminal screw 18 with the square nut 17.
A square nut 17 is placed next to the support part 7 through the square nut 17. As shown in FIG. 4, the second terminal 19 has a length less than half that of the first terminal 13, and has a continuous vertical connecting piece 20 hanging from its side and a horizontal connecting piece 21 connected to its lower end. horizontal connecting piece 2
A U-shaped fuse holder portion 22 is continuously formed at the end of the fuse holder 1 . This terminal 19 is made by punching and bending a single plate into a predetermined shape. And terminal board 19
Terminal screw mounting slit 23 and mounting hole 24 in a
is formed, and the terminal screw 2 with nut is inserted into the slit 23.
5 is passed through the mounting hole 24, and the driving stud 26 is passed through the mounting hole 24, and is fixed in the mounting hole 9 by driving. At this time, the horizontal connecting piece 21 passes through the slit 12, and the fuse holder portion 22 is housed in one end of the fuse housing groove 6. In the third terminal 27, the upper edge of the U-shaped fuse holder part 28 is continuous with one side of the substantially square terminal plate 27a for soldering, and a retaining protrusion 29 is cut and raised on both sides of the fuse holder part 28. ing. The fuse holder part 28 is housed in the other end of the fuse housing groove 6, and the soldering terminal part 27a is supported by the partition part 30 and the side step 31a of the central partition part 31, which constitute the support part of the body 1. . At this time, the inner surface of the fuse accommodating groove 6 has a locking part 32 as shown in FIG. terminal plate 27a is held at the same time. Further, the tip end 27b of the terminal plate 27a is connected to the center partition 3.
The terminal board 2 for soldering is locked in a locking part 33 for preventing floating formed on the upper part of the side step 31a of the soldering terminal board 2.
7a is securely fixed.

The fuse 3 is inserted into the fuse housing groove 6 as described above.
Fuse holder parts 22, 2 arranged at both ends of
8, the connection is maintained.

The lead wires are connected to one end of the body 1 using terminal screws 18 and 25, and the other end of the body 1 is connected by soldering. On the other hand, when removing the fuse 3, use the screwdriver 3 as shown in Figure 5.
Pass the tip of the fuse through the slit 12 and apply it to the end of the fuse 3, and use the side edges of the body 1 as leverage to pry it up.

With this configuration, the retaining protrusion 29 can also serve as a means for fixing the soldering terminal portion 27a, which simplifies the structure.
Since the space required for soldering can be minimized, it can be made compact. Further, since it is fixed by a retaining protrusion 29 cut and raised on the fuse holder portion 28, it can be securely fixed by attaching the fuse 3. Furthermore, since the soldering terminal part 27a extends from one end of the fuse holder part 28, when soldering the lead wire to the soldering terminal part 27a, the soldering iron does not hit the fuse attached to the fuse holder part 28. It is safe and has no Furthermore, the slit 12 makes it easy to remove and replace the fuse 3. As a modified example, as shown in FIG. 6, if a notch 35 is also formed in the side wall of the body 1 corresponding to the slit 12, the operation will be easier.

As described above, the fuse-equipped terminal block of this invention has a U-shaped fuse holder part with a retaining protrusion cut and raised outward on both sides thereof, and a protrusion extending outwardly from one end of the fuse holder part. It has a terminal with a soldering terminal portion extending therefrom, a supporting portion for supporting the soldering terminal portion, and a fuse housing groove for housing the fuse holder portion, and the retaining protrusion is engaged with the fuse holding groove. The body is provided with a locking portion for preventing the fuse holder portion from coming off on the inner surface of the fuse accommodating groove, and a lifting prevention locking portion for locking onto the tip of the soldering terminal portion. , has the following effects.

In other words, since it also serves as a locking piece to prevent one end of the soldering terminal from lifting up, there is no need for a space for fixing the soldering terminal, simplifying the structure, and the soldering terminal is U-shaped. Since it extends outward from one end, the soldering iron does not touch the fuse when soldering the lead wire to the soldering terminal section with the fuse stored in the fuse holder section, making it possible to make it smaller and more compact.
