Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明はシールリレーに関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a seal relay.
従来この糧のシールリレーは、ケースとベースの嵌合部
に一液性や二液性の接着剤を塗布し加熱してシールし製
造していた。Conventionally, this type of sealed relay was manufactured by applying a one-component or two-component adhesive to the fitting part of the case and base and heating it to seal it.
従来技術で説明したシールリレーは、接着剤を使用して

も加熱する必要があり、この長い加熱時間により生産性
が悪くなると共に高温加熱を長時間行うので、折角調整
していたリレーの動作特性が便化してしまうとｂう問題
があった。Since the seal relay described in the prior art uses adhesive, when the amount of adhesive used is large, the adhesive wraps around inside the relay and causes contact failure or malfunction of the contacts. In addition, in order to cure the adhesive and seal it, it is necessary to heat it at a high temperature of 100°C or more for approximately 30 to 60 minutes or more, and this long heating time reduces productivity and requires high temperature heating for a long time. There was a problem that the operating characteristics of the relay that had been adjusted were changed.
本発明は前記問題点に着目して改善を図ったものであっ
て、その目的とするところは動作特性が安定し、接触信
頼性が高く生産性の良いシールリレーを提供することに
ある。The present invention is an attempt to improve the above-mentioned problems, and its purpose is to provide a sealed relay with stable operating characteristics, high contact reliability, and good productivity.
本発明はケースとベースの嵌合部に埋設したヒータ線に
電流を通・鑞し、ベースとケース嵌合面を溶融してケー
ス内部を密封することにより動作特性の安定したシール
リレーとするものである。The present invention provides a sealed relay with stable operating characteristics by passing current through and brazing the heater wire buried in the fitting part of the case and the base, melting the fitting surface of the base and the case, and sealing the inside of the case. It is.
以下本発明の一実施例を図面に基づき説明する。An embodiment of the present invention will be described below based on the drawings.

的、機械的に接続された複数の端子５が突出してｂる。Figure 1 (a) ~ -1 is false, 1 is PBT in the relay body.
It is arranged on a base 3 made of a thermoplastic resin material such as. A plurality of terminals 5 protrude from one surface of the base 3 and are electrically and mechanically connected to the main body l.
２はベース３と同じく熱可塑性樹脂材料よりなる箱状を

ター線４が一部を露出して一体に埋設されて−る。2 is a box-shaped case made of a thermoplastic resin material like the base 3, and a heater wire 4 such as a nichrome wire is partially exposed and buried in the opening edge of the case.
尚、前記ヒーター線番の両端は一部が上下に重なり埋設
されると共にケース２の外部へ引き出されている。Note that both ends of the heater wire number are partially overlapped and buried, and are also drawn out to the outside of the case 2.
前記ケース２をベース３に嵌合した状態を表わすものが

１図（Ｃ）の如く溶融しケース２内のりＶ−本体１が密
封されるものである。FIG. 1(b) shows a state in which the case 2 is fitted to the base 3, and the case 2 and the base 3 are fitted in elastic contact via the heater wire 4. In this fitted state, when a current is applied to the heater wire 4, approximately 3
When heat is generated at 00 DEG C. or more, the fitting surface 6 of the case 2 and base 3 melts as shown in FIG. 1(C), and the V-main body 1 inside the case 2 is sealed.
上記の如く、シールするまでの時間が数秒であり、ケー
ス２とベース３間に高温を加えるのみであるからリレー
本体１の特性変化に対する影響が極めて小さいものであ
る。As mentioned above, since it takes several seconds to seal and only high temperature is applied between the case 2 and the base 3, the effect on changes in the characteristics of the relay body 1 is extremely small.

。The heater wire 4 can be used as long as it can uniformly melt the fitting surfaces of the case 2 and the base 3 and provide stable sealing inside the case 2. There is no question that it could be buried all together on the third side.

ある。FIG. 3 shows another embodiment of the buried heater wire 4, which intersects between both ends drawn out to the outside.
Since it is wrapped twice around the fitting surface, the fitting surface 6 of the case 2 and base 3 can be melted more stably.

益である。As described above, the present invention is to embed a heater wire integrally in the substantially opening edge of the case or the outer periphery of the base, and to apply current to the heater wire to melt the base and the case fitting surface, thereby sealing the inside of the case. As a result, there is no need to use adhesive as in the past, so it is possible to obtain a sealed relay with stable operation and high contact reliability without causing poor contact or malfunction due to adhesive wrapping around. Since the high temperature and long-time heating necessary for curing is unnecessary, it is advantageous that a one-seal relay with extremely small change in operating characteristics can be obtained with high productivity.
