Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a storage container used for an instant starter device such as a fluorescent lamp, such as an electronic starter or a mechatronic starter.

<Prior art> In general, prior art in the field of starters for fluorescent lamps includes, for example, Design Registration No. 171915 or ELECTRONIC PARTS CATALOG 1978.
(Published by the Japan Electronics Industry Association) Page 111 There are storage containers that use approximately cylindrical shapes for electronic components such as electrolytic capacitors.

On the other hand, in a conventional glow starter, an insulating paper 30 is inserted into an aluminum storage container 10 having a fixing part as shown in FIGS. Some containers consist of a pair of storage containers with tubes, capacitors, and pins mounted and inserted, and then fixed by bending the fixing part. Also, Figure 10 a, b, c, d, e

Some containers consist of a pair of storage containers in which a pin is mounted, inserted while rotating half a turn, fitted and fixed, and then fixed at the stop portion with an adhesive.

<Problems to be Solved by the Invention> Incidentally, the above-mentioned storage container (FIG. 9) requires the unit cost of the insulating paper 30, the labor of assembling and inserting it, and the process of bending the fixing portion of the storage container 10, which is labor intensive. Sexuality becomes worse. Similarly, in the case of the resin container (FIG. 10), there were problems such as the need for rotating and fitting the containers, the unit price of the adhesive, the trouble of fixing them, and the time required for the adhesive to dry. On the other hand, the external dimensions of the above-mentioned storage container are standardized according to JIS standards, and the internal volume is sufficient to accommodate conventional glow discharge tubes and capacitors, but electronic starter devices and other equipment require many electronic components. The disadvantage is that the internal volume is small due to high-density packaging. Furthermore, the high-voltage pulse voltage generated when starting a fluorescent lamp varies depending on the lamp output, but is approximately 800 to 3000V. Therefore, high voltage is applied to each component that is mounted in a high density such as an electronic starter, and even if there is insulating paper in the storage container, the high voltage pulse voltage will discharge, which is dangerous and also causes high humidity. location, etc. (e.g. lighting of refrigerated cases with fluorescent lights,
It is completely unsuitable for use during the rainy season, etc., as it has no insulation resistance. Further, in the case of a resin container which is rotated and fitted together, there is a problem in that when high-density mounted electronic components are rotated and inserted, they may become strained and the components may come into conductive contact with each other, destroying the starter function.
On the other hand, with the shift to electronic starters, improvements in performance (e.g. instant start characteristics, operating temperature characteristics, etc.) and innovative designs are required, and the conventional design of a simple cylindrical shape lacks marketability and adds value. However, there are problems in that it cannot be used as a container for housing the instantaneous starter device that is mounted in a high density, which is the object of the present application.

<Purpose of the invention> Therefore, in order to eliminate the above-mentioned conventional drawbacks, the present invention aims to secure the internal volume of the storage container, adopt a novel industrial design,
The purpose of the present invention is to provide a storage container that has insulation resistance, simplifies storage assembly, is inexpensive, and is highly marketable.

<Means for Solving the Problems> The structure of the present invention to achieve the above object includes a storage container having a plurality of side wall deep grooves on the inner wall that serve as a rotation stopper and a plurality of fitting grooves, and a storage container on the outer periphery. The side wall is composed of a terminal board provided with a plurality of anti-rotation protrusions that can be fitted in correspondence with the deep grooves of the side wall, and a plurality of fitting protrusions that can be fitted in correspondence with the fitting grooves; The deep groove is characterized in that it is formed over the entire length of the inner wall of the storage container.

<Function> According to the present invention, a plurality of concave side wall deep grooves are arranged and formed in the inner circular side wall of the storage container by the above-mentioned means, so that the internal storage volume can be effectively ensured. The deep grooves serve as guide grooves for printed wiring boards, etc., and can accommodate high-density mounted printed wiring boards. This prevents the components from coming into contact with each other during insertion, and allows the mounted components to be stably fixed in the vertical and horizontal directions within the container without touching the inner walls. Further, since a plurality of fitting grooves are formed on the inner wall of the storage container, the terminal board can be press-fitted and fixedly stored with one touch, thereby improving workability during storage. The deep groove on the side wall of the storage container fits with the anti-rotation convex portion of the terminal plate to form a pair of storage containers, so when it is attached by rotation crimp to the starter socket provided in the fluorescent light fixture. This serves to prevent the storage container and terminal board from rotating.

<Example> Next, an example of this invention will be described below with reference to the drawings.

1 to 3 show the terminal board 2 fitted into the storage container 1, and FIGS. 4a and 4b show a basic pair of storage container and terminals showing one embodiment of the present invention. It is a board. In the figure, reference numeral 1 denotes a storage container made of a resin with excellent heat resistance and insulation resistance, such as polycarbonate.
One side wall deep groove 1a and two fitting grooves 1b are arranged and formed, and the cross section of the storage container 1 is shown in FIG.
As shown in b and c, the side wall deep groove 1a is connected to the storage container 1.
A deep gutter is formed from the top to the bottom of the
The fitting groove 1b is formed into a concave groove that fits into the upper part, and the inner wall 1c has a shape having a step at the upper part.

As shown in FIG. 4b, a pin 3 that is conductively fitted to the starter socket is fixed to a terminal plate 2 made of Bakelite or the like having excellent insulating properties. and fitting groove 1b
Terminal plate 2 so that it fits well in the position corresponding to
A rotation stopper convex portion 2a and a fitting convex portion 2b are arranged on the outer periphery of the container 1, and a pair of containers is formed by the container 1 shown in FIG. 1A and the terminal plate 2 shown in FIG.

Next, the storage state will be explained according to FIGS. 6a and 6b. FIG. FIG. 3 is a reference side view showing a mounting state connected to pin 3; FIG. 1b is a cross-sectional view showing the instantaneous starter device housed in the storage container 1, and shows the four concave side wall deep grooves 1a.
This ensures sufficient storage space. The two lower side wall deep grooves 1a also function as guide grooves when inserting the printed wiring board, and also fix the printed wiring board in the vertical and horizontal directions so that high-density mounted components can be stored in the storage container. The two upper side wall deep grooves 1a and inner wall 1c of the inner wall 1 are not in contact with each other.

Thus, as shown in the perspective view of FIG. 7, the press-fitted state of the pair of storage containers described above is such that the printed wiring board is guided and inserted into the two side wall deep grooves 1a that also serve as guide grooves at the bottom of the storage container 1, and then, The fitting groove 1a of the storage container 1 and the fitting protrusion 2b of the terminal plate 2 are press-fitted and fixed. The housing container 1 and the terminal plate 2 are well fitted together as shown in the cross sections shown in FIGS. 5a, b, and c.

Furthermore, in the above-described implementation, the external shape of the storage container 1 can be easily and freely created with a design consisting of a series of knurled narrow grooves along the portion corresponding to the outer side of the side wall deep groove 1a. In addition, due to the creation of the above-mentioned knurled grooves, the contact friction resistance between the storage container and the fingers increases as shown in Fig. 8, making it easier to attach the container to the fluorescent lamp with less slippage. It has advantages such as being able to be attached to. Furthermore, since the side wall deep groove 1a is aligned with the mold removal direction during molding, it is easy to manufacture the mold even with an innovative design, improves workability during molding, and prevents sinkage caused by resin molding conditions, etc. This technology solves the technical problem by eliminating the need for dents (indentations), and because it is a resin container, it is possible to provide a storage container for an instant starter device for a fluorescent lamp that is inexpensive and highly marketable, without having to consider electrical insulation resistance. This leads to

In addition, with the structure shown in FIGS. 4a and 4b described above, the pair of storage containers themselves have a function of not rotating due to the engagement of the side wall deep groove 1a of the storage container 1 with the anti-rotation protrusion 2a of the terminal plate 2. .

<Effects of the invention> Since the present invention has the above-mentioned configuration, the storage space for the instantaneous starter device mounted in high density can be secured by the deep groove on the side wall of the storage container.
Their structure allows the printed wiring board to be easily guided and inserted. This has the advantage of preventing the parts from coming into contact with each other during insertion and stably fixing them in the vertical and horizontal directions within the container.

Further, the terminal plate can be press-fitted and fixed with one touch through the fitting groove of the storage container, and work efficiency during storage can be improved.

Furthermore, the configuration of the deep grooves on the side walls of the pair of storage containers and the anti-rotation protrusion on the terminal plate can serve to prevent rotation when the socket of the fluorescent lamp is installed.

In addition, the deep grooves on the side walls are aligned with the mold removal direction, making it easy to manufacture the mold, improving workability and molding conditions during molding, and because it is a resin container, it has excellent insulation resistance. This has the effect of producing a storage container for an instantaneous starter device for a fluorescent lamp that is inexpensive and highly marketable.
