Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention is a terminal block such as a terminal block in which a required number of rail-shaped channel bases are fitted and arranged in close contact with each other in the longitudinal direction of the channel bases. The present invention relates to a storage case for storing a product for sale and distribution.

<Prior Art> Generally, in a control panel or the like that connects an extremely large number of terminals, it is inefficient to individually attach terminal blocks such as a large number of terminal blocks for connecting the terminals.
A plurality of terminal blocks are fitted into a rail-shaped channel base having a required length to form a block terminal arranged and fixed in a close contact state, and the block terminals are mounted in a control panel.

Such a block terminal is provided with locking pieces 1 from both ends of a base 1a having a substantially U-shaped cross section as shown in FIG. 4, for example.
A stopper 3 is fixed to one end of a rail-shaped channel base 1 formed by extending b and 1c as shown in FIG. 5, and a pair of terminal plates 2a as shown in FIG. Terminal block 2 with terminal screws 2b and 2c attached
After mounting the mounting portion 2d on the locking pieces 1b, 1c from the other end side of the channel base 1 and sequentially mounting them, and after aligning a required number of terminal blocks 2 in close contact with each other, the end plate 4 is attached. By fixing the stoppers 3 to the other end portion of the channel base 1 while pressing the stoppers 3 toward the terminal block 2 side by interposing, a required number of terminal blocks 2 are sandwiched and fixed by the pair of stoppers 3. .

Further, the terminal block 2 has a main body integrally formed of an insulating material such as plastic, and a partition plate 2e ensures electrical insulation from other terminal blocks 2 adjacent to each other. The central partition wall 2f, which is divided into two, secures electrical insulation between the pair of terminal screws 2b and 2c. still,
The mounting portion 2d has a shape that can be adapted to both types of mounting rails whose tips are inwardly facing inward as shown by the one-dot chain line in FIG. 4 and mounting rails whose two forks are branched inward and downward as shown by the two-dot chain line. It has become.

<Problems to be Solved by the Invention> By the way, when the terminal block 2 is put into the sales and distribution process, as shown in FIG. 3, the terminal block 2 is stored in a storage box 5 arranged in a plurality of rows and shipped. The operation of packing the terminal block 2 in the storage box 5 is performed manually because it is difficult to automate, which complicates the work and is extremely inefficient.

Moreover, even on the side that uses this terminal block 2, when assembling the block terminal, take out the required number of terminal blocks 2 from the storage box 5,
Since each terminal block 2 is inserted into and attached to the channel base 1 one by one, a complicated work is performed, and there is a problem that the number of assembling steps of the block terminal increases.

The present invention has been made in view of the above conventional problems, and can automatically store a terminal block in the manufacturing process thereof. When assembling a block terminal, a required number of terminal blocks can be used as a channel base. It is a technical object to provide a storage case for a terminal block that can be easily and instantly attached to a housing.

<Means for Solving the Problems> According to the present invention, as a technical means for achieving the above-mentioned problems, the storage case of the terminal block is configured as follows. That is, in a case in which a mounting portion is fitted into a rail-shaped channel base and a terminal block such as a terminal block in which a plurality of terminals are arranged in close contact with each other in the longitudinal direction of the channel base is accommodated, a tubular shape with at least one end opened Then, a long-hole-shaped notch is formed on one side surface of the tubular shape from the opening end to the other end along the longitudinal direction, and the cross section in the lateral direction is used as a contact surface of the terminal block to another terminal block. The outline of the above is surrounded by an inner surface, and an area capable of including a projecting portion with respect to the contour of the contact surface of the channel base inserted into the mounting portion is added.

<Operation> Since the storage case of the present invention has a cylindrical shape with one end open, the opening should be installed so as to face the transfer direction of the terminal blocks that are transferred in close contact in a predetermined number in the manufacturing process. Can automatically pack this terminal block.

Also, when assembling a block terminal using the terminal block housed in this storage case, a channel base is provided between each terminal block and the inner surface of the storage case in the vicinity of one side surface where the slotted notch is formed. Since there is a gap that can be inserted into the mounting portion of each terminal block, the channel base is inserted into the storage case while being inserted into the mounting portion. At this time, each of the internal terminal blocks can be visually inspected and contacted through the notches.Therefore, put the fingers next to the required number of terminal blocks through the opening and separate them from the terminal blocks that cannot be taken out, and separate the channel base into this. When the channel base is taken out from the storage case with the opening facing slightly downward after being inserted until the tip touches the finger, the required number of terminal blocks are taken out from the storage case while being attached to the channel base.

<Embodiment> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of an embodiment of the present invention, and FIG. 2 is a cross-sectional view in the lateral direction thereof. In these figures, channel base 1 and terminal block 2
Are the same as those shown in FIGS. 3 to 5, and are therefore given the same reference numerals.

Further, the storage case 6 of the present invention is integrally formed of transparent plastic into a substantially rectangular tube shape with one end open, and one side 6c of the rectangular tube has the other end along the longitudinal direction from the opening 6a. A long hole-shaped notch 6b is formed up to.
Then, as shown in FIG. 2, the cross-sectional shape in the lateral direction is
A notch on one side 6c in the cross-sectional area that encloses the contour of the contact surface of the terminal block 2 to the other terminal block 2 with the inner surface.
A portion where the channel base 1 provided by forming outward bulging portions 6d and 6e on both sides of 6b is inserted into the mounting portion 2d so that the channel base 1 projects from the contour of the contact surface of the terminal block 2. The cross-sectional area is added. Also, along the notch 6b, terminal block 2
6f is attached to indicate the number of.

Since the storage case 6 is in the shape of a rectangular tube having the opening 6a at one end, in the manufacturing process of the terminal block 2, the number of terminal blocks 6 that can be stored in the storage case 6 are set as one set and transferred in a close contact state. When the storage cases 6 are sequentially installed with the openings 6a facing each other in the transfer direction, the corner terminal blocks 2 for each set are automatically inserted into the storage cases 6 from the openings 6a. Can be packed. Then, a lid body (not shown) integrally formed at the edge of the opening 6a or a separate lid body (not shown)
If the opening portion 6a is covered by the above, there is a slight gap on the inner surface side of the one side surface 6c, but in this state it can be put into the sales and distribution process without trouble.

When assembling a block terminal using the terminal block 2 stored in the storage case 6,
After opening the lid, the channel base 1 is fitted with the locking pieces 1b, 1c in the mounting portions 2d of the terminal blocks 2 as shown by the arrow in FIG. 1 and the one-dot chain line in FIG. While inserting it into the storage case 6. At this time, the bulges 6d and 6e
And the step portion of the one side surface 6c functions as a guide when the channel base 1 is inserted. Then, since each terminal block 2 inside and the channel base 1 to be inserted can be seen through the notch 6b, it is necessary to put a finger into the storage case 6 from the notch 6b with the required number of scales 6f as a mark and take it out. Put the fingers between the innermost part of the terminal block 2 and the other part, and insert the channel base 1 until the tip of the channel base 1 touches the finger, and then turn the opening 6a slightly downward. When the channel base 1 is taken out from the storage case 6 in this state, the required number of terminal blocks 2 are automatically taken out from the storage case and the other terminal blocks 2 are blocked by the finger. It does not fall off and remains in the storage case 6.

The present invention is not limited to the above description and the contents of the drawings, and may include various modifications without departing from the scope of the claims. For example, since the notch 6b is provided so that the inside can be seen, it is not always necessary to form the transparent material as in the embodiment, and the scale 6f is not an essential element. Further, the length may be set to an arbitrary length according to the number of terminal blocks 2 stored.

<Effects of the Invention> As described above, according to the terminal block storage case of the present invention, since the terminal block has a cylindrical shape with at least one end opened, the terminals can be installed by making the openings face each other in the transfer direction of the terminal block in the manufacturing process. Blocks can be automatically packed.

Also, when assembling a block terminal using the terminal block on the user side, the channel base is stored while inserting it into the mounting part of each terminal block in the gap between each terminal block and the inner surface where the notch of the storage case is formed. After inserting into the case and separating the terminal block to be left in the storage case by inserting fingers etc. from the notch, take out the channel base from the storage case and store it with the required number of terminal blocks attached to the channel base. It can be taken out from the case, complicated mounting work of the terminal block to the channel base can be eliminated, and the number of steps for assembling the block terminal can be considerably reduced.
