Abstract

PURPOSE:To enable taking a surface-mounted type relay out of a tray and prevent deformation of the terminals. CONSTITUTION:There are provided a tray 1 having a plurality of recess 1a which communicate with one another by communicating channels 1b and a sheet 2 which covers the recesses 1a of the tray 1 each recess holding a surface- mounted type relay 3 with bent terminals 3a, bent outward after being drawn out, and is put in tight contact with the relays 3 and the tray 1 by removing the air from the recesses 1a through the communicating channels 1b. As a result, even in the case where some room is allowed between each of the relays 3 and the recess 1a to enable taking the relays 3 out of the tray 1, the removal of the air from the recesses 1a through the channels 1b makes the sheet 2 tightly attach to the relays 3 and the tray 1 and keeps the relays 3 from moving inside the recesses 1a even when taken or vibrated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay packaging container.

[0002]

2. Description of the Related Art Conventionally, there is a packaging container of this type as shown in FIG. This is a tray 11 formed in a box shape with thick paper, and a rug 12 formed in a flat plate shape with a soft material such as sponge and laid on the bottom surface of the tray 11.
And a cover 13 which is formed in a box shape from thick paper or the like and which is fitted on the tray 11.

The relay 14 to be packaged has a plurality of terminals 14a which are installed upright straight to the outside.
The rug 12 is pierced into the rug 12 to be positioned side by side in the tray 11, and the cover 13 fitted to the tray 11
The terminal 14a is fixed so as not to come off from the rug 12 by being covered with.

As another conventional example, there is one shown in FIGS. 4 and 5. This is composed of a tray 21 having a plurality of recesses 21a formed by forming a thick insulating sheet, and a cover 22 integrally formed and continuously provided on one side of the tray 21.

The relay 23 to be packaged is composed of a plurality of bent terminals which are led out to the outside and then bent outward at a right angle.
It is a so-called surface mount type relay that has a terminal 23a and is soldered by mounting the terminal 23a on the copper foil part on the surface of the printed circuit board.
The cover 22 is fitted on the tray 21 in a state of being accommodated in the tray 21.

[0006]

In the conventional packaging container for the relay shown in FIG. 3, the relay 14 to be packaged is used.
Can be positioned side by side by simply piercing the rug 12 with the terminals 14a that are erected straight up to the outside.Furthermore, the cover 13 can be fixed by fitting the cover 11 onto the tray 11. Since it can be packaged, it requires less space.

However, in the case of the surface mount type relay having the bent terminal 23a like the relay 23, the bent terminal 23a
The relay cannot be positioned because the rug cannot be pierced into the rug 12.

Therefore, when packaging the surface mount type relay 23, as in the conventional example shown in FIG. 4 and FIG.
By accommodating the relay 23 in the recess 21a provided in the
The relay is positioned.

However, the relay 23 is
Since it is housed with a slight margin between it and the recess 21a so that it can be removed from the tray 21, the recess 21
It will move within a. Then, the non-fixed terminal 23a may be deformed and may not be properly mounted on the copper foil portion when surface-mounted on the printed board.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a packaging container for a surface mount type relay capable of preventing deformation of terminals.

[0011]

In order to solve the above problems, a relay packaging container according to the present invention comprises a tray having a plurality of recesses communicating with each other through a communication passage and a tray containing the relays. And a sheet that can be adhered to the relay and the tray by degassing the air in the recess while passing through the communication path while covering the recess.

[0012]

According to the packaging container for the relay of the present invention described above,
Even if the surface mount type relay is housed with a slight margin between it and the recess so that it can be taken out from the tray, the sheet will adhere to the relay and tray by degassing the air in the recess through the communication passage. Therefore, the relay does not move in the recess even when vibration is applied.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 denotes a tray, which is formed into a box shape by forming a thick insulating sheet, and a plurality of rectangular recesses 1a are provided on one surface side of the tray in a row and a row. Adjacent recesses 1a are communicated with each other by a communication path 1b. Further, only one of the recesses 1a located at the four corners is provided with a communication passage 1c communicating with the outside of the tray 1. That is, all the recesses 1a communicate with each other through the communication passage 1b and also communicate with the outside of the tray 1 through the communication passage 1c.

2 is a sheet, which is a thin insulating sheet,
It is formed in a square shape that is one size larger than the outer shape of the tray 1.

3 is a relay to be packaged, and its terminals
As for 3a, a plurality of wires are led out from one side of the relay body to the outside in two rows and then bent outward at a right angle, and the bent portions are placed on the copper foil portion of the printed circuit board surface and soldered. It is a so-called surface mount type relay.

The relay 3 is packaged as follows. First, the relay 3 is housed in each recess 1a of the tray 1 with the terminal 3a side facing down. At this time, the relay
There is a slight margin between the tip of the terminal 3a and the side wall of the recess 1a so that the 3 can be taken out. Next, the sheet 2 is attached to one side of the tray 1 so as to cover the concave portion 1a, and in this state, a nozzle such as a proper nozzle is removed from the communication passage 1c communicating with the outside of the tray 1 provided in the concave portion 1a at the corner. When the air is sucked by the air jig, all the air in each recess 1a is degassed through the communication passage 1b, and the sheet 2 comes into close contact with the relay 3 and the tray 1 as shown in FIG. The jig is removed from the communication passage 1c, and the communication passage 1c is sealed with an adhesive tape or the like.

In such a relay packaging container, the surface mount type relay 3 is recessed so that it can be taken out from the tray 1.
Even if it is accommodated with a slight margin between 1a and the
By degassing the air from 1a through the communication passage 1b, the seat 2 will come into close contact with the relay 3 and tray 1, so that even if vibration is applied, the relay 3 will not move in the recess 1a, and therefore the terminals of the relay 3 will not move. The terminal 3a can be accurately mounted on the copper foil portion when it is surface-mounted on the printed circuit board without deformation.

In this embodiment, the seat 2 is the relay 3
And it remains in close contact with the tray 1, but if a cover that fits the tray 1 is fitted over the sheet 2, it will be strong and the appearance will be improved, and various indications will be displayed on the cover. it can.

If the sheet 2 is made transparent, the sheet 2
It is possible to check the relay 3 itself housed in the recess 1a of the tray 1 without peeling it off.

Further, in this embodiment, the sheet 2 is a tray.
It is prepared separately from 1 and is attached.However, if one end of the sheet 2 is adhered to one edge of the tray 1 in advance, the relay 3 will be stored in the recess 1a of the tray 1. After that, the sheet 2 can be easily attached to the tray 1 by folding it back around the one end to which the sheet 2 is attached.

[0022]

The packaging container for the relay of the present invention allows the air in the recess to pass through the communication passage even if the surface mount type relay is accommodated with a slight margin between the relay and the recess so that the relay can be taken out from the tray. Since the sheet comes into close contact with the relay and the tray when degassed, the relay does not move in the recess even when vibration is applied.Therefore, the terminals of the relay do not deform, and the copper is not The terminals can be accurately mounted on the foil part.
