Description

[Detailed Description of the Invention] This invention relates to a choke coil storage case.

In conventional choke coils, both ends of the coil winding are generally soldered to lead wires, and the entire body is covered with, for example, a heat-shrinkable tube.

However, such conventional methods have poor workability when soldering the coil windings and lead wires, and require work to heat-shrink the tubes, etc., so they are not suitable for mass production and require cost reduction. There were various drawbacks such as difficulty in

The purpose of this invention is to eliminate the drawbacks of the above-mentioned conventional products and to provide a choke coil storage case that holds protruding iron cores at both ends of the choke coil and positions and stores the choke coil in a predetermined position. It is something to do.

This invention will be explained with reference to embodiments shown in the drawings.

1 to 4 show a cylindrical storage case 1 made of plastic according to this invention. The storage case 1 is composed of a right half 2 and a left half 3, each of which has a substantially semicircular cross section.

A protrusion 5.5 formed at one end of the left half part 3 is fitted into a recess 4, 4 formed at one end of the right half part 2, and a circular recess (not shown) formed at the other end of both halves 2, 3 is fitted. By fitting the ring 6 into the groove, the two halves 2, 3 can be assembled together.

A cylindrical attachment part 7 is integrally connected to one end of the right half part 2.

A pair of slots 8, 8 are formed facing each other on the inner circumferential surface of the mounting part 7, and at an angle of about 45 degrees from the slots 8, 8 is formed in the deep part of the mounting part 7.
Window holes 9.9 are formed at shifted positions, and slots 8, 8
and the window hole 9°9 communicate with each other at the inner part of the mounting portion 7.

At the center of the upper part of the right half 2, a locking part 10 extending along the longitudinal direction is protruded by two pieces 11.11, thereby forming a square hole 12.

In the figure, reference numeral 13 indicates windows for heat radiation of the choke coil, which are formed at eight locations in each of both halves 2 and 3.

As shown in FIGS. 5 and 6, the inner peripheral surface of the right half 2 has three protrusions 15 and 15 that hold the peripheral surface of the choke coil 14.
．． 15, and a similar protrusion (not shown) is also formed on the inner circumferential surface of the left half portion 3.

Inside the right half 2, at both ends of the choke coil 14,
Iron core protrusions 16 protruding from both ends of the choke coil 14
．． A pair of flexible retainers 17,18 are provided, each retaining a retainer 16.

As shown in FIG. 6, the holding parts 17 and 18 are parallel parts 17 that extend parallel to each other and hold the core protrusion 16 from above and below.
at 18a, inward protruding parts 17b, 18b that protrude inward from the parallel parts 17a, 18a and sandwich the core protruding part 16 toward the protrusion 15, and the parallel parts 17a, 18
It consists of outward protruding parts 17c and 18c that protrude outward from a, and the outward protruding parts 17c and 18c are attached to the ends of the coil winding before soldering the coil winding of the choke coil 14 and the lead wire. The winding is for so-called wire processing where it is kept fixed.

One end of the coil winding of the choke coil 14 is connected to the storage case 1.
It is soldered to a metal plate 19 disposed inside via a lead wire 20 or directly, and the other end is an outwardly protruding portion 17c.
Alternatively, it is soldered to the lead wire 21 at 18c.

As shown in FIG. 7, the mounting portion 7 has a pair of protrusions 23 formed on the outer peripheral surface near the tip of the cylindrical fuse holder 22.
．． The fuse holder 22 can be attached by fitting the protrusions 23 into the slots 8, 8 and then rotating them by about 45 degrees to fit the protrusions 23, 23 into the window holes 9, 9.

A fuse 25 is connected to the fuse holder 22 via a spring 24.
is accommodated, and due to the action of the spring 24, the fuse 25
The tip is pressed against a metal plate 19.

Figures 8 and 9 show the fuse 25 and choke coil 14.
A box 31 for an electrical device such as a car radio or car stereo that is supplied with power from a power source (for example, a car battery) (not shown) via the bottom plate of the box 31 can be inserted into the square hole 12 of the storage case 1. A projecting portion 32 is formed.

When using the above, inward protruding portion 17b,
18b by widening the gap between the core protrusions 16.1.
6, the core protrusion 16°16 will move to the holding part 17.1.
8, thereby fixing the choke coil 14 at a predetermined position on the right half 2.

Subsequently, each end of the coil winding is attached to the outwardly projecting portion 17c or 1.
When the winding is fixed around 8c, the lead wires 20 and 21 are attached to these.
can be easily soldered.

When the protruding part 32 of the box body 31 is inserted into the square hole 12 of the storage case 1 in which the choke coil 14 is housed in the interior and the fuse holder 22 is attached to the end in this way, the locking part 10 protrudes. The storage case 1 is fixedly attached to the box body 31 by being engaged with the portion 32 .

Note that the shape of the holding portions 17 and 18 is not limited to those of the above embodiment, and the shape and structure of the storage case 1 are not limited to those of the above embodiment. Waist fuse holder 2
2 may be integrated with the storage case 1 in advance,
Further, the locking portion 10 and the projecting portion 32 are not limited to the shape and arrangement of the above embodiment, and it goes without saying that this invention can be modified and repaired in various ways to the above embodiment.

Since this invention is constructed as described above, it is possible to hold the core protruding from both ends of the choke coil using only one half of the storage case, and in this state, each end of the coil winding cannot be wound. Soldering the lead wire can be done by fixing it to a fixed part, so it is extremely easy to solder the coil winding and the lead wire, improving work efficiency. The choke coil can be stored inside the case just by assembling it, and there is no need to do any work such as heat-shrinking heat-shrinkable tubes, making it suitable for mass production, stabilizing quality and reducing costs. It has excellent effects such as:
