2. Description of the Related Art There is known an electromagnetic switch of a type in which a solenoid, a plunger that reciprocates by the action of a solenoid and a spring, and a contact that is interrupted by the movement of the plunger are incorporated in a switch case. This type of electromagnetic switch is equipped with a terminal fixing terminal to which the end of the cable from the starter motor or battery is connected, and a fuse holder into which a fuse is inserted. Among those provided, a spare fuse holding portion provided on a cover is also known (see Patent Document 1).
Japanese Utility Model Publication No. 64-55534

しかるに、上記文献1に記載の従来のものは、カバーを装着した際にカバーの内側に保持されたスペアヒューズが干渉することのないようにするための逃げをスイッチケース側に設けており、スペアヒューズの保持部をカバーに設けるために、スイッチケースの構造にまで影響を及ぼしている。スペアヒューズの保持部を設けるためにスイッチケースの構造が制約を受けることは、電磁スイッチの設計上は好ましいことではない。   However, the conventional device described in the above-mentioned document 1 is provided with a relief on the switch case side so that the spare fuse held inside the cover does not interfere when the cover is attached. Since the fuse holding portion is provided on the cover, the structure of the switch case is affected. In view of the design of the electromagnetic switch, it is not preferable that the structure of the switch case is restricted in order to provide the holding portion for the spare fuse.

このような課題を解決し、スイッチケースの構造に影響を及ぼさずに、他の部品と干渉しないスペアヒューズの保持部を設けることのできる電磁スイッチのカバーを提供するため、本発明の請求項1は、一対のケーブル(7a・7b)の端末が接続された部分(ボルト8・圧着端子10)同士間を仕切る仕切壁(15)を当該カバー(11)に一体形成すると共に、該仕切壁にスペアヒューズ(20)の保持部(保持溝21)を設けたことを特徴とするものとした。   In order to solve such problems and to provide a cover for an electromagnetic switch that can be provided with a spare fuse holding portion that does not interfere with other components without affecting the structure of the switch case, the present invention provides a cover for an electromagnetic switch. Is formed integrally with the cover (11) with a partition wall (15) for partitioning the portions (bolts 8 and crimp terminals 10) to which the ends of the pair of cables (7a, 7b) are connected. A holding part (holding groove 21) for the spare fuse (20) is provided.

また本発明の請求項2は、当該カバーを透明な合成樹脂材で形成し、カバーの上壁(23)内面にスペアヒューズの上面を対向させるものとした。   According to a second aspect of the present invention, the cover is made of a transparent synthetic resin material, and the upper surface of the spare fuse is opposed to the inner surface of the upper wall (23) of the cover.

このような本発明の請求項1の構成によれば、カバーに保持されたスペアヒューズ自体が一対のケーブルの接続端子間を仕切る仕切壁の一部となるので、既存の電磁スイッチのレイアウトに影響を及ぼさずにスペアヒューズの保持部をカバー設けることができる。   According to such a configuration of claim 1 of the present invention, the spare fuse itself held by the cover becomes a part of the partition wall that partitions between the connection terminals of the pair of cables, which affects the layout of the existing electromagnetic switch. It is possible to provide a cover for the spare fuse holding portion without affecting the width.

また請求項2の構成によれば、スペアヒューズの有無をカバー外から確認することができ、しかもスペアヒューズの上面に刻印されているアンペア数をもカバーを外さずに確認し得るので、組込み忘れや誤組込みの防止が計れる。   Further, according to the configuration of claim 2, the presence or absence of a spare fuse can be confirmed from the outside of the cover, and the amperage stamped on the upper surface of the spare fuse can be confirmed without removing the cover. And prevent mis-installation.

以下に添付の図面を参照して本発明について詳細に説明する。   Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

図1は、本発明が適用された自動車のエンジン始動回路の断続に用いられる電磁スイッチを示している。この電磁スイッチ1は、ソレノイド、ソレノイドとばねの作用によって往復動するプランジャ、及びプランジャの動きによって断続される接点などをスイッチケース2の内部に組み込んだものであり、文献1に記載の従来形式のものと同等の構造を有しており、その内部構造についての詳細な説明は省略する。   FIG. 1 shows an electromagnetic switch used to intermittently connect an engine start circuit of an automobile to which the present invention is applied. The electromagnetic switch 1 incorporates a solenoid, a plunger that reciprocates by the action of the solenoid and a spring, and a contact that is intermittently moved by the movement of the plunger. The detailed structure of the internal structure is omitted.

スイッチケース2の上面には、制御線を接続するコネクタ3と、回路に接続されるヒューズ4を取り付けるヒューズ装着部5と、一対のケーブル接続ターミナル6a・6bとが設けられている。一対のケーブル接続ターミナル6a・6bには、スタータモータからのケーブル7a並びにバッテリーからのケーブル7bの圧着端子処理された各端末がそれぞれボルト8をもって固定してあり、一対のケーブル接続ターミナル6a・6b間には、これらを仕切るリブ9が立設されている。   On the upper surface of the switch case 2, a connector 3 for connecting a control line, a fuse mounting portion 5 for attaching a fuse 4 connected to a circuit, and a pair of cable connection terminals 6a and 6b are provided. In the pair of cable connection terminals 6a and 6b, the terminals 7c of the starter motor and the cable 7b from the battery that are subjected to crimp terminal processing are respectively fixed with bolts 8, and between the pair of cable connection terminals 6a and 6b. Are provided with ribs 9 for separating them.

一対のケーブル7a・7bの各端末に固着された圧着端子10には、ボルト締結部10aと、ケーブル端末圧着部10bと、ケーブルの被覆結合部10cとが一体形成されており、ボルト締結部10aと、ケーブル端末圧着部10bおよびケーブル被覆結合部との間が略直角に曲折されており、ケーブル端末圧着部10bおよびケーブル被覆結合部10cがスイッチケース2の一側から突出し、両ケーブル7a・7bは下向きに延出されている。   The crimp terminal 10 fixed to each end of the pair of cables 7a and 7b is integrally formed with a bolt fastening portion 10a, a cable terminal crimp portion 10b, and a cable sheathing joint portion 10c, and the bolt fastening portion 10a. And the cable terminal crimping part 10b and the cable sheath coupling part are bent at a substantially right angle, and the cable terminal crimping part 10b and the cable sheath coupling part 10c protrude from one side of the switch case 2, and both cables 7a and 7b Is extended downward.

この電磁スイッチ1のヒューズ装着部5およびケーブル接続ターミナル6a・6bの周囲は、略透明な絶縁性に富む合成樹脂材にて下向きに開放された箱形に形成された着脱自在なカバー11にて覆われている。   The periphery of the fuse mounting portion 5 and the cable connection terminals 6a and 6b of the electromagnetic switch 1 is a detachable cover 11 formed in a box shape opened downward with a synthetic resin material having a substantially transparent insulating property. Covered.

カバー11には、スイッチケース2の互いに反対側を向く一対の側面に形成された一対の突条12に係止してカバー11の位置決めを行うスリット13と、一対のケーブル接続ターミナル6a・6b間を仕切るようにスイッチケース2の上面に設けられたリブ9の上端縁を受容する溝14と、一対の圧着端子10のケーブル端末結合部10bおよびケーブル被覆結合部10c同士間を仕切る仕切壁15と、ヒューズ4及びヒューズ装着部5を覆うヒューズカバー16とが一体形成されている。   The cover 11 includes a slit 13 for positioning the cover 11 by being engaged with a pair of protrusions 12 formed on a pair of side surfaces facing the opposite sides of the switch case 2, and a pair of cable connection terminals 6a and 6b. A groove 14 for receiving the upper edge of the rib 9 provided on the upper surface of the switch case 2 so as to partition the cable, and a partition wall 15 for partitioning between the cable terminal coupling portion 10b and the cable sheath coupling portion 10c of the pair of crimp terminals 10. The fuse 4 and the fuse cover 16 that covers the fuse mounting portion 5 are integrally formed.

ヒューズカバー16の両側部には、スイッチケース2側に形成された一対の突起17に係合する孔18がその下端に設けられた揺動片19が形成されており、これらの孔18が、揺動片19の材料自体の弾性によって突起17に弾発係合することにより、スイッチケース2にカバー11が固定されている。このカバー11は、一対の揺動片19の上端部を指先で把持して挟み付けることにより、揺動片19の下端が拡開して突起17との係合が解かれ、簡単に取り外すことができるようになっている。   On both sides of the fuse cover 16, there are formed swinging pieces 19 provided at the lower ends thereof with holes 18 that engage with a pair of protrusions 17 formed on the switch case 2 side. The cover 11 is fixed to the switch case 2 by elastically engaging the protrusion 17 by the elasticity of the material of the swing piece 19 itself. The cover 11 is easily removed by grasping and pinching the upper ends of the pair of swing pieces 19 with the fingertips so that the lower ends of the swing pieces 19 are expanded and the engagement with the projections 17 is released. Can be done.

仕切壁15には、スペアヒューズ20を保持する保持溝21が形成されており、カバー11を形成した材料自体の弾性により、軽圧入した状態でスペアヒューズ20を保持溝21内に保持することができるようにされている。この構成によれば、保持溝21に保持されたスペアヒューズ20自体が、一対の圧着端子10のケーブル端末結合部10bおよびケーブル被覆結合部10c同士間を仕切る仕切壁15の一部となるので、既存の電磁スイッチのレイアウトに影響を及ぼさずにスペアヒューズ20の保持部をカバー11に設けることができる。なお、保持溝21を形成した仕切壁15の端縁部には、保持溝21に対してスペアヒューズ20を着脱する際にスペアヒューズ20を指先で摘み易くするために、切欠部22が設けられている。   A holding groove 21 for holding the spare fuse 20 is formed in the partition wall 15, and the spare fuse 20 can be held in the holding groove 21 in a light press-fitted state due to the elasticity of the material forming the cover 11 itself. It has been made possible. According to this configuration, the spare fuse 20 itself held in the holding groove 21 becomes a part of the partition wall 15 that partitions between the cable terminal coupling portion 10b and the cable sheath coupling portion 10c of the pair of crimp terminals 10, The holding portion of the spare fuse 20 can be provided in the cover 11 without affecting the layout of the existing electromagnetic switch. A notch 22 is provided at the edge of the partition wall 15 in which the holding groove 21 is formed so that the spare fuse 20 can be easily picked up with a fingertip when the spare fuse 20 is attached to or detached from the holding groove 21. ing.

スペアヒューズ20は、回路に接続された実ヒューズ4と同様に、その頭部を上向きにして保持溝21内に装着されており、その上面をカバー11の上壁23の内面に対向させている。従って、透明なカバー11の外からその装着状態を確認することができると共に、頭部の上面に刻印されたアンペア数もカバー11を外さずに容易に視認可能なようになっている。これにより、組込み忘れや誤組込みの防止を計っている。ここで一対の仕切壁15で形成された保持溝21の対向内面の下部には、図3に示すように、スペアヒューズ20の電極部の厚さに対応してその隙間を狭くするための突条24が形成されており(図2においては図示省略した)、これにより、スペアヒューズ20を装着する際に、上下の方向性を誤ることのないようにされている。   Like the actual fuse 4 connected to the circuit, the spare fuse 20 is mounted in the holding groove 21 with its head facing upward, and its upper surface faces the inner surface of the upper wall 23 of the cover 11. . Therefore, it is possible to confirm the mounting state from the outside of the transparent cover 11 and to easily recognize the amperage stamped on the upper surface of the head without removing the cover 11. In this way, we are trying to prevent forgetting or mis-installation. Here, in the lower part of the opposing inner surface of the holding groove 21 formed by the pair of partition walls 15, as shown in FIG. 3, a protrusion for narrowing the gap corresponding to the thickness of the electrode part of the spare fuse 20. The strips 24 are formed (not shown in FIG. 2), so that when the spare fuse 20 is mounted, the vertical direction is not mistaken.
