[Prior art]

従来この種、小型継電器を図８及び図９に従って説明する。図において、１は小型継電器であり、該小型継電器１のベース２にケース３を嵌合して被蔽してある。該小型継電器１は接点（図示せず）の切替えにより、スイッチング動作をなすように構成されている。 A conventional compact relay of this type will be described with reference to FIGS. In the figure, reference numeral 1 is a small relay, and a case 3 is fitted on a base 2 of the small relay 1 to cover it. The small relay 1 is configured to perform a switching operation by switching contacts (not shown).

【０００３】また、該ベース２には、端子４，４が固定され、該ベース２の上面より上方へ突出いてある。そして、該端子４，４を他の電子部品に接続して電力の供給等をできるように構成している。一方、該端子４，４間のベース２上面には凹部５を形成してある。該凹部５は、ベース２を樹脂にて成形する際に、樹脂の量を該凹部５にて調整できるように設けられている。即ち、樹脂の量が多いときには凹部５が小となり、少ないときには大きくなって、該ベース２の成形が容易となる。Further, terminals 4 and 4 are fixed to the base 2 and project upward from the upper surface of the base 2. Then, the terminals 4 and 4 are connected to other electronic components so that power can be supplied. On the other hand, a recess 5 is formed on the upper surface of the base 2 between the terminals 4 and 4. The recess 5 is provided so that the amount of the resin can be adjusted by the recess 5 when the base 2 is molded with the resin. That is, when the amount of resin is large, the concave portion 5 becomes small, and when it is small, the concave portion 5 becomes large and the base 2 is easily molded.

【０００４】斯くして、端子４，４を他の電子部品に接続すれば、小型継電器１に電力を供給すれば、該小型継電器１がスイッチンク動作をなす。Thus, if the terminals 4 and 4 are connected to other electronic components and the small relay 1 is supplied with electric power, the small relay 1 performs a switching operation.

【０００５】[0005]

[Problems to be solved by the device]

上述した従来の小型継電器１は、端子４，４間のベース２上面に凹部５を形成して該ベース２の成形を容易にいていた。しかし、結露等により水滴がベース２上面に落下すると該凹部５に留まってしまう。従って、端子４，４がショートして小型継電器１が確実な動作をしない等の問題を生じている。 In the conventional small relay 1 described above, the recess 5 is formed on the upper surface of the base 2 between the terminals 4 and 4 to facilitate the molding of the base 2. However, if water drops fall on the upper surface of the base 2 due to dew condensation or the like, they will remain in the recess 5. Therefore, the terminals 4 and 4 are short-circuited and the small relay 1 does not operate reliably.

【０００６】そこで、小型継電器の端子のショートを防止して小型継電器の品質を向上するために解決せられるべき技術的課題が生じてくるのであり、本考案は該課題を解決することを目的とする。[0006] Therefore, there arises a technical problem to be solved in order to prevent the short circuit of the terminal of the small relay and improve the quality of the small relay, and the present invention aims to solve the problem. To do.

[Action]

この考案は、小型継電器の端子間のベース上面に中央部位を頂点として該ベースの側面へテーパ状に切欠した凹部を形成している。従って、該凹部に水滴が落下しても該水滴はベースの側面より流出する。従って、ベースの上面に水滴が留まることはなく、端子間のショートを防止する。 According to this invention, a recess is formed on the upper surface of a base between terminals of a small relay, the recess being formed by tapering a central portion to the side surface of the base. Therefore, even if water drops fall into the recesses, the water drops flow out from the side surface of the base. Therefore, water droplets do not remain on the upper surface of the base, which prevents a short circuit between terminals.

【Example】

以下、この考案の一実施例を図１乃至図６に従って説明する。図において、１０は小型継電器であり、図１及び図２に示すように、該小型継電器１０は上部のベース１１にケース１２を嵌合して被蔽されている。該小型継電器１０は可動接点（図示せず）と固定接点（図示せず）の接触、離間によりスイッチング動作をなすように構成され、各種電機製品等に組み込まれている。 An embodiment of the present invention will be described below with reference to FIGS. In the figure, 10 is a small relay, and as shown in FIGS. 1 and 2, the small relay 10 is covered with a case 12 fitted to an upper base 11. The small relay 10 is configured to perform a switching operation by contact and separation of a movable contact (not shown) and a fixed contact (not shown), and is incorporated in various electric products.

【００１０】該小型継電器１０は、ベース１１に端子１３，１３を固定してある。そして、該端子１３，１３を該ベース１１の上面より上方へ突出して他の電子部品に該端子１３，１３を接続できるように形成されている。尚、図中１４，１４は信号の入出力用の端子である。また、該小型継電器１０にはベース１１の上面であって、且つ、前記端子１３，１３の間に凹部１５を形成している。該凹部１５は左右の端子１３，１３間の前後方向に形成されてある。また、凹部１５は端子１３，１３間の中央部に頂点１６を形成し、そして、該頂点１６よりベース１１の側面１７，１７を下方へテーパ状に切欠して形成されている。即ち、該凹部１５の上面は屋根状に形成される。The small relay 10 has terminals 13, 13 fixed to a base 11. Then, the terminals 13 and 13 are formed so as to project upward from the upper surface of the base 11 so that the terminals 13 and 13 can be connected to other electronic components. In the figure, 14 and 14 are terminals for signal input / output. Further, the small relay 10 has a recess 15 formed on the upper surface of the base 11 and between the terminals 13 1, 13. The recess 15 is formed in the front-back direction between the left and right terminals 13, 13. Further, the concave portion 15 is formed by forming a vertex 16 at the central portion between the terminals 13 and 13, and cutting side surfaces 17 and 17 of the base 11 downward from the vertex 16 in a taper shape. That is, the upper surface of the recess 15 is formed like a roof.

【００１１】斯くして、端子１３，１３及び１４，１４を他の電子部品に接続して電力を供給すれば、小型継電器１０がスイッチング動作をなし、端子１４，１４から所定の信号が入出力される。また、ベース１１の上面に水滴が落下しても端子１３，１３間の凹部１５が屋根のようなテーパ状に形成されているため、該水滴は小型継電器１０の側方へ流出する。従って、端子１３，１３がショートすることはない。Thus, if the terminals 13, 13 and 14, 14 are connected to other electronic parts to supply electric power, the small relay 10 performs a switching operation and a predetermined signal is input from the terminals 14, 14. Is output. Further, even if a water drop falls on the upper surface of the base 11, the recess 15 between the terminals 13 and 13 is formed in a taper shape like a roof, so that the water drop flows out to the side of the small relay 10. Therefore, the terminals 13 and 13 are not short-circuited.

【００１２】図３乃至図７は他の実施例を示し、図３乃至図５に示す実施例は、ベース１１の上面の端子１３，１３を固定する部位に該ベース１１と一体成形にて座１８，１８を突設している。ベース１１に該座１８，１８を形成したことにより、端子１３，１３間の沿面距離が延長されるため、更に確実に端子１３，１３の絶縁を図ることができる。また、該座１８，１８を突設しても該座１８，１８は該端子１３，１３を他の電子部品に着脱する際の障害となることはない。FIGS. 3 to 7 show another embodiment. In the embodiment shown in FIGS. 3 to 5, the base 11 is integrally molded with the base 11 at a portion where the terminals 13 and 13 are fixed. 18 and 18 are projected. By forming the seats 18, 18 on the base 11, the creepage distance between the terminals 13, 13 is extended, so that the terminals 13, 13 can be more reliably insulated. Even if the seats 18 and 18 are provided in a protruding manner, the seats 18 and 18 do not become an obstacle when the terminals 13 and 13 are attached to and detached from other electronic parts.

【００１３】図６及び図７に示す実施例は、ケース１２よりもベース１１ａの外形を大に形成して該ベース１１ａとケース１２と段部１９を形成している。そして、該段部１９の下面を外側より内側へ向って上方へ斜傾して形成している。従って、ベース１１の上面より側面へ流出した水滴を該段部１９にて落下させ、小型継電器１０内へ水滴の侵入を防止する。In the embodiment shown in FIGS. 6 and 7, the outer shape of the base 11 a is made larger than that of the case 12 to form the base 11 a, the case 12 and the step portion 19. Further, the lower surface of the step portion 19 is formed so as to be inclined upward from the outside toward the inside. Therefore, the water droplets flowing out from the upper surface to the side surface of the base 11 are dropped at the step portion 19 to prevent the water droplets from entering the small relay 10.

【００１４】尚、本考案は、本考案の精神を逸脱しない限り種々の改変をなすことができ、そして、本考案が該改変せられたものに及ぶことは当然である。The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified version.

【００１５】[0015]

[Effect of device]

この考案は、上記一実施例に詳述したように、小型継電器の端子間に中央部位を頂点として側方へテーパ状に切欠した凹部を形成している。即ち、該凹部の上面は屋根状に形成され、該ベース上面に落下した水滴等を確実にベースの側面へ排出する。 In this invention, as described in detail in the above-mentioned one embodiment, the recesses are formed between the terminals of the small relay, and are formed by laterally tapering notches with the central portion as the apex. That is, the upper surface of the concave portion is formed like a roof, and water drops and the like that have fallen onto the upper surface of the base are surely discharged to the side surface of the base.

【００１６】従って、端子間のショートを防止して小型継電器の確実なる作動を可能とし、品質の向上にも寄与できる等、実用的価値のある考案である。[0016] Therefore, the invention is of practical value because it can prevent short-circuiting between terminals and enable reliable operation of a small relay, and contribute to quality improvement.
