本発明は密封形リレーの製造方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a sealed relay.
従来、密封形リレーとしては、第１図に示すよ
うに、上面に開口部２を設けた箱形のベース１内
に図示しないリレー本体を収納し、開口部２の段
部３にカバー４を設けたのち、開口縁部２ａとカ
バー４上にエポキシ樹脂等の密封樹脂を塗布して
加熱溶融・硬化させることとより、開口縁部２ａ
とカバー４の接合部の密封を行つていた。 Conventionally, as shown in FIG. 1, as a sealed relay, a relay main body (not shown) is housed in a box-shaped base 1 with an opening 2 on the top surface, and a cover 4 is attached to a step 3 of the opening 2. After forming the opening edge 2a, a sealing resin such as epoxy resin is applied onto the opening edge 2a and the cover 4, and the opening edge 2a is heated and melted and hardened.
and the joints of cover 4 were being sealed.
しかしながら、このものでは塗りむらによつて

工程とはまつたく独立した別工程であるために、
製造工程上無駄が多いという欠点を有していた。 However, in this case, the appearance is damaged due to uneven coating, the sealing performance is impaired due to the formation of pinholes, and the sealing resin enters into the base from the joint between the opening edge 2a and the cover 4. This had the disadvantage of interfering with the operation of the In addition, in order to print the model number etc. on this type of sealed relay,
After the sealing resin had hardened, the cover 4 was printed using a so-called hot stamp, but since the printing process and the above-mentioned sealing process were completely independent processes,
It has the disadvantage that there is a lot of waste in the manufacturing process.
本発明はこのような欠点に鑑みてなされたもの
で、その目的は印字工程と密封工程とを一連に関
連させることにより製造工程を簡略化して無駄を

ある。 The present invention was made in view of these drawbacks, and its purpose is to simplify the manufacturing process and eliminate waste by associating the printing process and the sealing process in a series, and to impair the appearance and sealing performance. To provide a method for manufacturing a sealed relay that does not have any adverse effects on the operation of the relay body.
以下、本発明を添付図面を参照して説明する。 The present invention will now be described with reference to the accompanying drawings.

リプロピレン樹脂が望ましい。 FIG. 2 shows a sealing sheet 5 used in the manufacturing method according to the present invention, on which a printed sheet material 7 having a different color from the sheet material 6 is adhered onto a sheet material 6 made of a heat-melting material. It has a three-layer structure in which a protective film 8 made of a heat-melting material is adhered to a printing sheet material 7, and its total thickness H is 0.8 to 1.1.
mm, and the sheet material 6 accounts for 98% of it. As specific materials, the sheet material 6 is made of epoxy resin,
Vinyl chloride resin is preferred, printing sheet material 7 is preferably aluminum foil or polycarbonate resin, and protective film 8 is preferably polyurethane resin, polyester resin, or polypropylene resin.

構成している。 As for the relay itself, base 1 shown in Figure 1,
A device equipped with a cover 4 is used. in this case,
The cover 4 forms the same plane as the opening edge 2a of the base 1.

離可能となる。 As shown in FIG. 3, this relay is conveyed at a constant pitch in the direction of arrow A on a horizontal plane, and the sealing sheet 5 is also rolled up in advance, and the sheet material 5 is placed on the bottom side of the opening edge of the base 1. It is conveyed at a constant pitch in the direction of arrow A on the same plane as 2a. In the position in FIG. 3, the sealing sheet 5 is placed over the opening edge 2a of the base 1 and the cover 4,
A stamp (not shown) in which arbitrary characters or symbols, such as the characters "TYPE G2T" are engraved in a convex shape, is pressed onto the sealing sheet 5 in a heated state. At this time,
The printing sheet material 7 and the protective film 8 corresponding to the markings of the stamp are fused and adhered onto the sheet material 6, and the printing sheet material 7 and the protective film 8 other than the printed portion can be peeled off from the sheet material 6.
一方、印字シート材７、保護膜８は位置と

は「TYPE G2T」の文字が残ることとなる。 On the other hand, the printing sheet material 7 and the protective film 8 are peeled off from the sheet material 6 between the positions and can be conveyed in the direction of arrow B by being clamped by a pair of rollers 10, 10. Therefore, when the relay and the sealing sheet 5 that have completed the printing process are transported to the position and the rollers 10 and 10 are rotated in synchronization, the printing sheet material 7 and the protective film 8 other than the printing part are automatically removed. As a result, the letters "TYPE G2T" remain on the sheet material 6.
つづいて、位置においてシート材６を適宜手

からはみ出した不要部分をカツトする。この場
合、加熱はシート材６の全面に施してもよいが、
少なくとも密封に必要な開口縁部２ａとカバー４
の接合部に対応する部分のみでもよい。 Subsequently, the sheet material 6 is heated by an appropriate means at the position to melt and adhere to the relay, and unnecessary portions protruding from the relay are cut off. In this case, heating may be applied to the entire surface of the sheet material 6, but
At least the opening edge 2a and cover 4 necessary for sealing
Only the part corresponding to the joint part may be used.
なお、保護膜８は印字シート材７を保護するも

てもよい。 Although the protective film 8 protects the printed sheet material 7, it is not necessarily necessary. In addition, the cover 4 is omitted and the sealing sheet 5 is placed on the opening 2 of the base 1.
The sheet material 6 may also serve as a cover, so to speak, by directly covering the sheet material 6 and performing the printing process, peeling process, and sealing process.
以上の説明で明らかなように、本発明によれ

とのない密封形リレーとすることができる。 As is clear from the above description, according to the present invention, the printing process is performed at the position, the sealing process is performed at the position, and the sealing process is performed at the position.
The peeling process can be performed continuously between these parts, and this type of sealed relay can be manufactured extremely efficiently and without waste. In addition, compared to the conventional method that applies sealing resin,
There are no defects such as uneven coating, pinholes, or sealing resin entering the base, and the appearance is
It is possible to provide a sealed relay with good sealing performance and no adverse effects on the relay body.
