Description

本発明は、車両に搭載されるスタータなどに用いられる継電器に関する。   The present invention relates to a relay used for a starter or the like mounted on a vehicle.

一般に、車両用エンジンを始動する場合には、スタータを起動させるために、スタータのスイッチコイルへの通電が行われる。このとき、車両側電源系統からスタータスイッチに通電される電流は比較的大きいものとなる。そのため、直接スタータスイッチへの通電を行わず、継電器(スタータリレー)を用いて通電を行う技術が適用されている。継電器を用いる場合、車両側から比較的小さな電流を継電器の励磁コイルに流し、継電器の電気接点を閉路させることにより、この継電器の電気接点を介して、車両用電源からスタータのスイッチコイルへの通電を行う。   Generally, when starting a vehicle engine, energization of a starter switch coil is performed in order to start the starter. At this time, the current supplied to the starter switch from the vehicle-side power supply system is relatively large. For this reason, a technique is applied in which the starter switch is not energized directly but energized using a relay (starter relay). When using a relay, a relatively small current flows from the vehicle side to the excitation coil of the relay, and the electrical contact of the relay is closed, thereby energizing the starter switch coil from the vehicle power supply via the electrical contact of the relay. I do.

継電器は一対の主端子を持つ構成である。一対の主端子のうち一方の主端子は、車両側電源に直接または間接的に接続され、常時電位を持った活線となる。他方の主端子は、例えば、スタータのスイッチコイルに接続される導電部となる。
継電器が内燃機関のスタータに搭載される場合、例えば、水がかかる等の被水環境で使用されることになる。被水環境にあっては、継電器の露出された通電部は、電気腐食を起こしやすい。これは、継電器の露出した通電部の中でも、常時活線となる一方の主端子にて顕著となる傾向がある。 The relay has a pair of main terminals. One main terminal of the pair of main terminals is directly or indirectly connected to the vehicle-side power supply, and becomes a live line having a constant potential. The other main terminal is, for example, a conductive part connected to the switch coil of the starter.
When the relay is mounted on a starter of an internal combustion engine, for example, it is used in a wet environment where water is applied. In a wet environment, the exposed current-carrying portion of the relay is liable to cause electrical corrosion. This tends to be conspicuous at one main terminal that is always live, even in the exposed energized portion of the relay.

ここで、従来技術として、継電器の電気接点となる電磁スイッチを付勢するための電流を入切する補助スイッチを備えたエンジンスタータが開示されている(例えば、特許文献１参照)。
また、従来技術として、主端子部に絶縁性の別部材を組み付け、主端子とアース回路となる部品との沿面距離を増やすことで、電気耐食性を向上させる継電器が開示されている(例えば、特許文献２参照)。 Here, as a prior art, an engine starter including an auxiliary switch for turning on and off a current for energizing an electromagnetic switch serving as an electrical contact of a relay is disclosed (for example, see Patent Document 1).
Further, as a conventional technique, a relay that improves electrical corrosion resistance by assembling another insulating member to the main terminal portion and increasing the creepage distance between the main terminal and a component that becomes a ground circuit is disclosed (for example, a patent Reference 2).

特許文献２に開示された継電器にあっては、主端子とアース回路となる部品との沿面距離を増やしているが、別部材の組み付けが必要であり、コストＵＰに繋がっていたという問題があった。また、特許文献２の継電器にあっては、主端子の常時活線部が露出した状態に構成されており、被水環境にあっては電気腐食を起こしやすい問題があった。   In the relay disclosed in Patent Document 2, although the creepage distance between the main terminal and the component that becomes the ground circuit is increased, there is a problem in that it is necessary to assemble another member and the cost is increased. It was. Moreover, in the relay of patent document 2, it was comprised in the state in which the live line part of the main terminal was always exposed, and there existed a problem which is easy to raise | generate an electric corrosion in a wet environment.

この発明は、上記のような課題を解決するためになされたものであり、継電器のキャップ形状変更のみによって、大幅なコストアップを招くことなく、電気耐食性を向上させることが可能な継電器を得ることを目的としている。   This invention was made in order to solve the above problems, and to obtain a relay capable of improving the electrical corrosion resistance without incurring a significant cost increase only by changing the cap shape of the relay.

実施の形態１．
本発明の実施の形態１の継電器１について、図１および図２を用いて説明する。図１は、継電器１の正面図、図２は、継電器１の要部断面側面図である。この継電器１は、例えば、車両側電源系統の電流をオン/オフさせるために用いられるものである。
図１に示すように、継電器１には、正面となる主面部側に一対の主端子を構成する主端子３１、３２が設けられている。この主端子３１、３２は、継電器１の本体内の電気接点（図示せず）により接離自在に構成されている。この電気接点は、継電器１本体内の励磁コイル（図示せず）により駆動され、また、図１に示すように、継電器１の主面部側には、励磁コイルに接続された励磁端子２が設けられている。 Embodiment 1 FIG.
The relay 1 of Embodiment 1 of this invention is demonstrated using FIG. 1 and FIG. FIG. 1 is a front view of the relay 1, and FIG. 2 is a cross-sectional side view of the main part of the relay 1. This relay 1 is used, for example, to turn on / off the current of the vehicle-side power supply system.
As shown in FIG. 1, the relay 1 is provided with main terminals 31 and 32 constituting a pair of main terminals on the main surface side that is the front surface. The main terminals 31 and 32 are configured to be contactable and separable by electrical contacts (not shown) in the main body of the relay 1. This electrical contact is driven by an excitation coil (not shown) in the relay 1 main body, and as shown in FIG. 1, an excitation terminal 2 connected to the excitation coil is provided on the main surface side of the relay 1. It has been.

ここで、主端子３１は、車両側電源に直接接続されており、常時電位を持った活線状態となっている。もう一方の主端子３２は、スタータと接続されている導電部である。主端子３１は、第一の主端子に相当し、主端子３２は、第二の主端子に相当する。   Here, the main terminal 31 is directly connected to the vehicle-side power supply, and is in a live line state with a constant potential. The other main terminal 32 is a conductive part connected to the starter. The main terminal 31 corresponds to a first main terminal, and the main terminal 32 corresponds to a second main terminal.

そして、図１に示すように、本発明の継電器１は、継電器１の本体部を被覆する非導電性部材よりなるキャップ７を備えている。このキャップ７は、励磁コイルおよび電気接点を被覆するとともに、主端子３１、３２を露出させる主面部７ａを備え、さらに、一方の主端子３１の周囲に配設され、キャップ７の主面部７ａから突出する隔壁部９を備えている。このキャップ７に一体形成された隔壁部９は、本発明の特徴となる部分であり、主端子３１を、他の導電部から隔てるように配設されている。   And as shown in FIG. 1, the relay 1 of this invention is equipped with the cap 7 which consists of a nonelectroconductive member which coat | covers the main-body part of the relay 1. As shown in FIG. The cap 7 includes a main surface portion 7a that covers the exciting coil and the electrical contacts and exposes the main terminals 31 and 32. Further, the cap 7 is disposed around one main terminal 31 and extends from the main surface portion 7a of the cap 7. A protruding partition wall 9 is provided. The partition wall portion 9 formed integrally with the cap 7 is a portion that is a feature of the present invention, and is disposed so as to separate the main terminal 31 from other conductive portions.

ここで、キャップ７は、主端子３１、３２を露出させる主面部７ａ、主端子３１と他の導電部を隔てる隔壁部９以外の構成部も有している。例えば、図２に示すように、主端子３１、３２を露出させる面部の高さと、励磁端子２やネジ６等を露出させる面部の高さが異なる場合には、励磁端子露出面部やネジ露出面部等が、一続きのキャップ７の異なる高さに形成された状態となる。
なお、図２に例示するように、主端子３１、３２と、励磁端子２、ネジ６等は、電気的離間のために異なる高さにレイアウトされることが多いが、これに限らず、共通の高さの主面部７ａから、上記端子やネジ等を露出させることも可能である。 Here, the cap 7 also has components other than the main surface portion 7a that exposes the main terminals 31 and 32 and the partition wall portion 9 that separates the main terminal 31 from other conductive portions. For example, as shown in FIG. 2, when the height of the surface portion that exposes the main terminals 31 and 32 is different from the height of the surface portion that exposes the excitation terminal 2, the screw 6, etc., the excitation terminal exposed surface portion and the screw exposed surface portion. Are formed at different heights of the continuous cap 7.
As illustrated in FIG. 2, the main terminals 31 and 32, the excitation terminal 2, the screw 6, and the like are often laid out at different heights for electrical separation. It is also possible to expose the terminals, screws, and the like from the main surface portion 7a having a height of.

励磁端子２は、継電器１の本体内の励磁コイルに電気的に接続されている導電部である。この励磁端子２は、継電器１の主面部側を覆うキャップ７に固定されるとともに、このキャップ７から露出した状態となっている。
キャップ７の内部には、上述のように、励磁コイルにより駆動される継電器１の電気接点が設けられており、一対の主端子を構成する主端子３１、３２の各々は、電気接点の固定側接点に対して一体となるように設けられている。 The excitation terminal 2 is a conductive part that is electrically connected to the excitation coil in the main body of the relay 1. The excitation terminal 2 is fixed to a cap 7 that covers the main surface side of the relay 1 and is exposed from the cap 7.
As described above, the electrical contact of the relay 1 driven by the exciting coil is provided inside the cap 7, and each of the main terminals 31 and 32 constituting the pair of main terminals is on the fixed side of the electrical contact. It is provided so as to be integrated with the contact.

また、キャップ７はネジ６によりケース８に締結されており、ケース８はフロントブラケット（図示せず）に固定されている。
そして、ケース８はスタータ本体もしくは車両に固定され、電源のマイナス電位と電気的に接続された状態であることが多い。その場合、ネジ６はケース８を介して電源のマイナス側と繋がっている導電部となる。
また、ケース８がマイナス電位の場合には、励磁コイルのマイナス電位側の一端を、励磁端子２に接続せず、継電器１内で電気的にケース８に接続して用いる場合がある。このとき、励磁コイルのマイナス電位側の一端を接続するための励磁端子２は設ける必要がない。 The cap 7 is fastened to the case 8 with screws 6, and the case 8 is fixed to a front bracket (not shown).
In many cases, the case 8 is fixed to the starter body or the vehicle and is electrically connected to the negative potential of the power source. In that case, the screw 6 becomes a conductive part connected to the negative side of the power supply through the case 8.
When the case 8 has a negative potential, one end on the negative potential side of the exciting coil may not be connected to the exciting terminal 2 but may be electrically connected to the case 8 in the relay 1 in some cases. At this time, it is not necessary to provide the exciting terminal 2 for connecting one end of the exciting coil on the negative potential side.

図２は、この発明の実施の形態１による隔壁部９を一部断面図で示した要部断面側面図である。この図２に示すように、主端子３１、３２の各々は、継電器１の本体側に配線２１、２２を接続している。配線２１、２２は、電源や他の機器へ伸びる導線部１０ａ、１０ｂと、その導線部１０ａ、１０ｂの端部に接続され、主端子３１、３２に固定される端子部１１ａ、１１ｂを備えた構成である。配線２１、２２の端子部１１ａ、１１ｂは、主端子３１、３２に、ナット４、ワッシャ５により固定されている。
また、主端子３１側に接続される配線２１の導線部１０ａは、隔壁部９の上端から外部へ引き出されている。 FIG. 2 is a cross-sectional side view of an essential part showing a partition wall 9 according to Embodiment 1 of the present invention in a partial cross-sectional view. As shown in FIG. 2, each of the main terminals 31 and 32 has wirings 21 and 22 connected to the main body side of the relay 1. The wirings 21 and 22 include conductor portions 10a and 10b extending to a power source and other devices, and terminal portions 11a and 11b connected to the ends of the conductor portions 10a and 10b and fixed to the main terminals 31 and 32. It is a configuration. The terminal portions 11 a and 11 b of the wirings 21 and 22 are fixed to the main terminals 31 and 32 by nuts 4 and washers 5.
Further, the conducting wire portion 10 a of the wiring 21 connected to the main terminal 31 side is drawn out from the upper end of the partition wall portion 9.

なお、図２に示すように、継電器１の下部にはサポート部１００が配置されている。サポート部１００は、スタータ本体と接続するための構成部であり、磁気回路の役割もあり、コイル等の部品を収納している。また、このサポート部１００は、キャップスイッチをネジにて固定し、キャップ固定用のネジを通ってグラウンドに繋がる回路の一部ともなっている。   In addition, as shown in FIG. 2, the support part 100 is arrange | positioned at the lower part of the relay 1. FIG. The support unit 100 is a component for connecting to the starter body, has a role of a magnetic circuit, and houses components such as a coil. The support unit 100 is also a part of a circuit that fixes the cap switch with a screw and connects to the ground through the cap fixing screw.

図１および図２に示したように、一対の主端子のうちの一方の常時活線となる主端子３１の周囲には、隔壁部９が設けられ、他の導電部となる他方の主端子３２、励磁端子２、ネジ６等との間の沿面距離を伸ばすことができる構成となっている。
この隔壁部９は、キャップ７の主面部７ａの一部を隆起させた形状であり、キャップ７と一体に非導電性部材で構成されている。 As shown in FIGS. 1 and 2, a partition wall 9 is provided around the main terminal 31 that is always live in one of the pair of main terminals, and the other main terminal that serves as another conductive portion. 32, the creeping distance between the excitation terminal 2, the screw 6 and the like can be increased.
The partition wall 9 has a shape in which a part of the main surface portion 7 a of the cap 7 is raised, and is configured of a non-conductive member integrally with the cap 7.

また、隔壁部９は、キャップ７の主面部７ａからの突出高さが、主端子３１より高くなるように設けられている。これにより、隔壁部９を設けない場合と比較し、本発明の継電器１は、常時電位を持った主端子３１と他の導電部との間の沿面距離を伸ばすことができる。沿面距離を伸ばすことで、リーク電流を抑制し、電気耐食性に優れた継電器１とすることができる。
さらに、キャップ７に隔壁部９を設けたことで、被水環境にあっても、主端子３１が水を被りにくい構成とすることができ、耐環境性を向上させることができる。 Further, the partition wall portion 9 is provided such that the protruding height of the cap 7 from the main surface portion 7 a is higher than that of the main terminal 31. Thereby, compared with the case where the partition part 9 is not provided, the relay 1 of the present invention can extend the creeping distance between the main terminal 31 having a constant potential and the other conductive part. By extending the creepage distance, it is possible to suppress the leakage current and to make the relay 1 excellent in electric corrosion resistance.
Furthermore, by providing the partition wall 9 on the cap 7, the main terminal 31 can be configured not to be covered with water even in a wet environment, and the environmental resistance can be improved.

ここで、主端子３１の通電部を露出させないために、隔壁部９で囲んだ領域の内側（以下、単に隔壁部９の内側とする。）を絶縁性部材（図示せず）で満たすことも有効である。図１に示すように、隔壁部９を筒形状に形成し、常時電位を持った主端子３１を、筒形状の隔壁部９で全周囲んだ場合、隔壁部９内側への絶縁性部材充填時、充填材が隔壁部９の外側に漏れにくく、作業が容易となる。
隔壁部９の内側を絶縁性部材で満たす場合、主端子３１に配線２１を接続した後に、隔壁部９の内側に絶縁性部材を充填し、固化させる。これにより、主端子３１を絶縁性部材に埋没させ、主端子３１の通電部となる露出面を絶縁性部材にて完全に覆い隠すことができ、電気耐食性、耐環境性に優れた継電器１を得ることが可能となる。この絶縁性部材には、例えば、シリコーン、エポキシ樹脂、ホットメルトを用いることができる。 Here, in order not to expose the energization portion of the main terminal 31, the inside of the region surrounded by the partition wall portion 9 (hereinafter simply referred to as the inside of the partition wall portion 9) may be filled with an insulating member (not shown). It is valid. As shown in FIG. 1, when the partition wall 9 is formed in a cylindrical shape and the main terminal 31 having a constant potential is entirely surrounded by the cylindrical partition wall 9, the insulating member is filled inside the partition wall 9. At this time, the filler is less likely to leak to the outside of the partition wall 9 and the operation becomes easy.
When the inside of the partition wall portion 9 is filled with an insulating member, after the wiring 21 is connected to the main terminal 31, the inside of the partition wall portion 9 is filled with an insulating member and solidified. As a result, the main terminal 31 can be buried in the insulating member, and the exposed surface to be the current-carrying portion of the main terminal 31 can be completely covered with the insulating member, and the relay 1 having excellent electric corrosion resistance and environmental resistance can be obtained. Can be obtained. For this insulating member, for example, silicone, epoxy resin, or hot melt can be used.

ここで、隔壁部９の内側を絶縁性部材により埋める場合、隔壁部９の高さは、配線２１の端子部１１ａの上端の高さ以上となるように構成する。これによれば、隔壁部９の上端まで絶縁性部材を満たすことで、配線２１の端子部１１ａを絶縁性部材によって完全に埋没させることができる。   Here, when the inner side of the partition wall 9 is filled with an insulating member, the height of the partition wall 9 is configured to be equal to or higher than the height of the upper end of the terminal portion 11 a of the wiring 21. According to this, by filling the insulating member up to the upper end of the partition wall portion 9, the terminal portion 11 a of the wiring 21 can be completely buried by the insulating member.

ここで、隔壁部９が、主端子３１の全周を囲む筒形状ではなく、欠けや切欠き（スリット）等を持つ形状であっても、常時電位を持った主端子３１を絶縁性部材で埋没することができれば、全周に隔壁部９を設けた場合と同様の効果を得ることができる。
また、主端子３１および端子部１１ａを露出させないために、上述のように隔壁部９の内側を絶縁性部材で満たして主端子３１および端子部１１ａを埋没させる構成とするのではなく、主端子３１および端子部１１ａの露出部分に、絶縁性部材を塗布した構成とすることも有効であり、同様の効果を得ることができる。 Here, even if the partition wall portion 9 is not in a cylindrical shape surrounding the entire circumference of the main terminal 31, but in a shape having notches or notches (slits), the main terminal 31 having a constant potential is made of an insulating member. If it can be buried, the same effect as when the partition wall 9 is provided on the entire periphery can be obtained.
Moreover, in order not to expose the main terminal 31 and the terminal portion 11a, the main terminal 31 and the terminal portion 11a are not buried and the main terminal 31 and the terminal portion 11a are buried, as described above. It is also effective to apply an insulating member to the exposed portions of 31 and the terminal portion 11a, and the same effect can be obtained.

さらに、上述の例において、隔壁部９は、常時電位を持った活線となっている主端子３１の周囲に配設することを示したが、主端子３１の周囲以外に、他方の主端子３２の周囲にも配設することも可能である。そして、主端子３２側にも隔壁部９を設けたことで、この主端子３２における電気耐食性、耐環境性を向上させることが可能となる。   Furthermore, in the above-described example, the partition wall portion 9 has been shown to be disposed around the main terminal 31 that is a live line having a constant potential, but in addition to the periphery of the main terminal 31, the other main terminal It is also possible to dispose around 32. And by providing the partition part 9 also on the main terminal 32 side, it becomes possible to improve the electrical corrosion resistance and the environment resistance of the main terminal 32.

また、ここで、継電器１の製造時、隔壁部９の内側において、配線２１の主端子３１への固定は、ナット４の締め付けによって行われる。このとき、ナット４の締め付けに伴って、配線２１の端子部１１ａおよび導線部１０ａがナット４とともに隔壁部９内で回転する状態となる場合がある。そこで、隔壁部９の内壁の形状を、配線２１の回り止めとして機能する形状に形成し、配線保持部９ａとする。この配線保持部９ａは、主端子３１の周囲を取り囲む隔壁部９の内壁部の一部であり、配線２１と内接する面部に相当する。   Further, here, when the relay 1 is manufactured, the wiring 21 is fixed to the main terminal 31 inside the partition wall 9 by tightening the nut 4. At this time, as the nut 4 is tightened, the terminal portion 11 a and the conductor portion 10 a of the wiring 21 may be rotated together with the nut 4 in the partition wall portion 9. Therefore, the shape of the inner wall of the partition wall portion 9 is formed into a shape that functions as a detent for the wiring 21 to form the wiring holding portion 9a. The wiring holding portion 9 a is a part of the inner wall portion of the partition wall portion 9 that surrounds the periphery of the main terminal 31, and corresponds to a surface portion inscribed with the wiring 21.

このような配線保持部９ａを隔壁部９の内壁側に設けることで、配線２１を主端子３１に固定する際に、配線２１を配線保持部９ａに内接させて保持させることができる。よって、ナット４の締め付けによる配線２１の移動を抑制することができ、作業者が手で配線２１を持ち、位置固定をする必要がなくなり、作業性を向上させることが可能となる。また、図１に示したように、配線保持部９ａを、隔壁部９内において、他の導電部から離れた位置に構成することにより、主端子３２や励磁端子２側に配線２１が近づくことを抑制することができる。これにより、電源に直接接続された配線２１の導線部１０ａが、同じ継電器１を構成する他部へ及ぼす電気的影響小さく抑制することが可能となる。   By providing such a wiring holding portion 9 a on the inner wall side of the partition wall portion 9, when the wiring 21 is fixed to the main terminal 31, the wiring 21 can be held in contact with the wiring holding portion 9 a. Therefore, the movement of the wiring 21 due to the tightening of the nut 4 can be suppressed, and it becomes unnecessary for the operator to hold the wiring 21 by hand and fix the position, thereby improving the workability. Further, as shown in FIG. 1, the wiring 21 is brought closer to the main terminal 32 and the excitation terminal 2 side by configuring the wiring holding part 9 a at a position away from other conductive parts in the partition part 9. Can be suppressed. Thereby, it becomes possible to suppress the electrical influence which the conducting wire part 10a of the wiring 21 directly connected to the power supply has on the other parts constituting the same relay 1 is reduced.

FIG. 3 is a cross-sectional side view of an essential part of the relay 1 according to the second embodiment of the present invention. In the relay 1 according to the first embodiment described above, the wiring 21 connected to the main terminal 31 is configured by the conductor portion 10a and the terminal portion 11a connected to the end portion thereof, and the height of the partition wall portion 9 is the terminal portion 11a. The case where the height is equal to or higher than the upper end of is illustrated. In this Embodiment 2, the case where the wiring 21 which comprises the relay 1 is the structure which attached the insulating tube 13 to the connection part which connects the conducting wire part 10a and the terminal part 11a is demonstrated.

配線２１の構成において、主端子３１に固定される端子部１１ａは、ナット４により締め付けられ、主端子３１と接続される平板部と、その平板部から立ち上がり、導線部１０ａの端部との接続を行う立ち上がり部により構成される。この端子部１１ａの立ち上がり部は、導線部１０ａとの接続部となる。これについては、先述の図２において示した通りである。この実施の形態２の継電器１では、図３に示すように、配線２１の端子部１１ａの立ち上がり部（接続部）に、絶縁性チューブ１３が装着されている。   In the configuration of the wiring 21, the terminal portion 11 a fixed to the main terminal 31 is tightened by the nut 4 and connected to the flat plate portion connected to the main terminal 31 and the end portion of the conducting wire portion 10 a rising from the flat plate portion. It is comprised by the rising part which performs. The rising part of this terminal part 11a becomes a connection part with the conducting wire part 10a. This is as shown in FIG. In the relay 1 according to the second embodiment, as shown in FIG. 3, the insulating tube 13 is attached to the rising portion (connecting portion) of the terminal portion 11 a of the wiring 21.

図３に示すように、この絶縁性チューブ１３は、配線２１の導線部１０ａの外装となる絶縁被膜および端子部１１ａの立ち上がり部に密着して固定され、主端子３１に近い側の一端は、隔壁部９内側に充填された絶縁性部材１４に埋没した状態となっている。そして、絶縁性チューブ１３の主端子３１に近い方の一端を、隔壁部９内の絶縁性部材１４に埋没させることで、端子部１１ａの通電部を絶縁性チューブ１３により完全に覆い隠すことが可能である。絶縁性チューブ１３を設けることは、端子部１１ａが、例えば大型の圧着端子であり、立ち上がり部が大きく、隔壁部９の外側まで延在する場合に、電気耐食性を確保するために有効となる。   As shown in FIG. 3, this insulating tube 13 is fixed in close contact with the insulating coating serving as the exterior of the conductor portion 10 a of the wiring 21 and the rising portion of the terminal portion 11 a, and one end near the main terminal 31 is It is in a state of being buried in the insulating member 14 filled inside the partition wall 9. Then, one end of the insulating tube 13 closer to the main terminal 31 is buried in the insulating member 14 in the partition wall portion 9, so that the current-carrying portion of the terminal portion 11 a can be completely covered by the insulating tube 13. Is possible. Providing the insulating tube 13 is effective for ensuring electric corrosion resistance when the terminal portion 11a is, for example, a large crimp terminal, has a large rising portion, and extends to the outside of the partition wall portion 9.

また、端子部１１ａの立ち上がり部が絶縁性チューブ１３により覆われているため、隔壁部９の高さを端子部１１ａの高さよりも低くすることができ、隔壁部９の内側に充填する絶縁性部材１４の使用量を少なくすることができ、電気性耐食性、耐環境性、コスト性に優れた継電器１を得ることが可能となる。   Moreover, since the rising part of the terminal part 11a is covered with the insulating tube 13, the height of the partition part 9 can be made lower than the height of the terminal part 11a, and the insulating property which fills the inside of the partition part 9 is filled. The use amount of the member 14 can be reduced, and the relay 1 having excellent electrical corrosion resistance, environmental resistance, and cost can be obtained.
