Abstract

PROBLEM TO BE SOLVED: To provide a coil terminal having a tangling portion with a sufficient yield and a high cutting property.SOLUTION: Coil terminals 37, 38 have a pin shape with a circular cross section, and tangling portions 37a, 38a with a regular square cross section having corners for cutting a coil are formed at upper ends of the coil terminals. Also, rotation-prevention portions 37b, 38b that are subject to press-processing into an approximate rectangular cross sectional shape and can prevent rotation are provided at its intermediate portion. Furthermore, the coil terminals 37, 38 are made of, for example, a wire of a copper-base material such as phosphor bronze of a diameter of 0.4 mm. Thereby, a material loss can be further reduced compared to a case when a belt-like thin metal plate is punched by a die to manufacture the coil terminals 37, 38. Also, the tangling portions 37a, 38a may have a cross section of a rectangular shape, a triangle shape, and an elliptical shape, preferably a shape having a corner capable of cutting a coil, without limiting to a square.

Description

本発明は、例えば、電磁継電器やスイッチなどに用いるコイルを絡げて切断できるコイル端子に関する。   The present invention relates to a coil terminal that can be wound by winding a coil used for, for example, an electromagnetic relay or a switch.

従来、コイルを絡げて切断するコイル端子として、特許文献1に、コイルの絡げ部が断面円形のコイル端子が開示されている。しかし、このコイル端子では、絡げ部の断面が円形であるので、コイルの引き出し線が切断しにくく、切断性能にバラツキがあった。このため、作業性が悪く、不良が起きやすいという問題があった。   Conventionally, Patent Document 1 discloses a coil terminal having a circular cross-section of a coil binding portion as a coil terminal for cutting a coil by winding it. However, in this coil terminal, since the cross section of the binding portion is circular, the coil lead wire is difficult to cut, and the cutting performance varies. For this reason, there existed a problem that workability | operativity was bad and it was easy to produce a defect.

特許第3,467,532号公報Japanese Patent No. 3,467,532

そこで、コイル端子としては帯状薄肉金属板からプレス金型で打ち抜いて断面方形としたものが製造され、打ち抜き時に生じたいわゆるカエリを利用し、絡げたコイルの引き出し線を切断することにより、絡げ作業の迅速性を確保していた。   Therefore, a coil terminal is manufactured by punching from a strip-shaped thin metal plate with a press die into a square cross section, and by using a so-called burr generated at the time of punching, the coiled coil lead wire is cut to create the coil terminal. The speed of work was ensured.

しかし、前述の工法では、打ち抜いたコイル端子以外の材料を廃棄していたので、材料ロスが多い。また、カエリを活用した場合でも、カエリの形状のバラツキにより、前記絡げ部に絡げたコイルの引き出し線の一部がヒゲ状になって残存するという問題があった。   However, in the above-described construction method, materials other than the punched coil terminals are discarded, so there are many material losses. Further, even when the burrs are used, there is a problem that a part of the lead wire of the coil entangled with the entangled portion remains as a beard due to variations in the shape of the burrs.

本発明は、前述の問題点に鑑みてなされたもので、歩留まりが良く、切断性の高い絡げ部を有するコイル端子を提供することを課題とする。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a coil terminal having a binding portion with good yield and high cutting performance.

前記課題を解決するため、本発明のコイル端子は、一端部にコイルの引き出し線を絡げる絡げ部を有する断面略円形のコイル端子であって、前記絡げ部に少なくとも1つのコイル切断用角部を形成したものである。   In order to solve the above-mentioned problems, the coil terminal of the present invention is a coil terminal having a substantially circular cross section having a binding portion that ties a coil lead wire at one end, and at least one coil cut is formed in the binding portion. A corner is formed.

コイル切断用角部でコイルを切断して、切断性を確保することにより、コイル巻回の作業性を向上できる。   The workability of coil winding can be improved by cutting the coil at the coil cutting corners to ensure cutting performance.

本発明の実施形態として、前記コイルの絡げ部が断面正方形を有していてもよい。また、他の実施形態としてコイルの絡げ部が、断面長方形であってもよく、断面三角形であってもよい。   As an embodiment of the present invention, the binding portion of the coil may have a square cross section. Further, as another embodiment, the coil binding portion may have a rectangular cross section or a triangular cross section.

本発明の異なる実施形態として、前記絡げ部の下方に扁平な回り止め部を形成しておいてもよい。
これにより、コイル端子の回り止め部をハウジングに組み付ければ、空回りを防止できるコイル端子が得られる。
As a different embodiment of the present invention, a flat anti-rotation portion may be formed below the binding portion.
Thereby, if the rotation prevention part of a coil terminal is assembled | attached to a housing, the coil terminal which can prevent idling will be obtained.

本発明の異なる実施形態として、略断面円形の線材から形成してもよい。
これにより、従来例のように帯状薄肉金属板を金型で打ち抜いてコイル端子を製造した場合よりも、歩留まりを著しく改善できる。
As another embodiment of the present invention, it may be formed from a wire having a substantially circular cross section.
Thereby, a yield can be remarkably improved as compared with the case where a coil terminal is manufactured by punching a strip-shaped thin metal plate with a die as in the conventional example.

The rotating arm portion 44 does not necessarily have an L shape, and may be a shape in which the tip end portion of the rotating arm portion 44 is bent, or may be a simple strip shape.

そして、前記ベース10に、前記電磁石部20および前記可動鉄片40を組み付ける場合には、前記スプール21の鍔部25に設けた軸受け部25aに可動鉄片40の軸部41を位置決めし、門型鉄芯30に可動鉄片40を重ね合わせた状態とする。そして、門型鉄芯30の脚部31,32の先端部を前記ベース10の圧入用凹部14,15に圧入し、前記圧入用凹部14,15内に設けた圧壊用リブ14a,15aを押し潰す。これにより、前記脚部31,32の先端部が前記圧入用凹部14,15の内側面にそれぞれ押し付けられ、位置決めされる(図5B参照)。同時に、門型鉄芯30に設けた突き出し突起34が絶縁壁11に設けた位置決め用凹部11a(図2)に嵌合する。また、可動鉄片40の軸部42を前記ベース10の軸受け部16bに回動可能な遊嵌状態とするとともに、抜け止め突起45を前記ベース10の抜け止め孔16aに嵌合して抜け止めする。   When the electromagnet portion 20 and the movable iron piece 40 are assembled to the base 10, the shaft portion 41 of the movable iron piece 40 is positioned on the bearing portion 25 a provided on the flange portion 25 of the spool 21, and the portal iron The movable iron piece 40 is superposed on the core 30. And the front-end | tip part of the leg parts 31 and 32 of the portal iron core 30 is press-fit in the press-fit recessed parts 14 and 15 of the said base 10, and the crushing ribs 14a and 15a provided in the said press-fit recessed parts 14 and 15 are pushed. Crush. Thereby, the front-end | tip part of the said leg parts 31 and 32 is each pressed against the inner surface of the said press-fit recessed parts 14 and 15, and is positioned (refer FIG. 5B). At the same time, the protrusion 34 provided on the portal iron core 30 is fitted into the positioning recess 11 a (FIG. 2) provided on the insulating wall 11. Further, the shaft portion 42 of the movable iron piece 40 is set in a loosely fitting state in which the shaft portion 42 can rotate on the bearing portion 16 b of the base 10, and the retaining protrusion 45 is fitted in the retaining hole 16 a of the base 10 to prevent it from coming off. .

なお、ベース10に電磁石部20を組み付けた場合には、図5A,5B,5Cに示すように、スプール21の鍔部24,25はベース10の絶縁壁11に当接しておらず、門型鉄芯30だけがベース10に当接している。このため、ベース10に対する電磁石部20の組立誤差が小さく、位置決め精度が高いので、設計通りの支持強度を確保できるとともに、動作特性の良い電磁継電器が得られるという利点がある。   When the electromagnet portion 20 is assembled to the base 10, as shown in FIGS. 5A, 5B, and 5C, the flange portions 24 and 25 of the spool 21 are not in contact with the insulating wall 11 of the base 10, and are portal-shaped. Only the iron core 30 is in contact with the base 10. For this reason, since the assembly error of the electromagnet part 20 with respect to the base 10 is small and the positioning accuracy is high, there is an advantage that a support strength as designed can be secured and an electromagnetic relay with good operating characteristics can be obtained.

カード50は、図14に示すように、前記ベース10の凹所12に収納可能な形状であり、その正面中央に設けた絶縁用凹部51の底面から操作突起52を突設してある。前記絶縁用凹部51は、前記ベース10の方形環状リブ13aに嵌合可能な外形寸法を有している(図4C)。一方、前記カード50は、その背面の上下縁部に一対の絶縁用リブ53,53を突設するとともに、前記操作突起52と同一軸心上に後述する可動接触片62に当接する突条54を設けてある。前記絶縁用リブ53は、後述する可動接触片62の上下縁部を仕切ることにより、絶縁距離を長くするためのものである(図4C)。また、前記カード50は、その片側縁部に、前記ベース10に設けた支持突部12aに嵌合する切り欠き部55を設けてある。
したがって、前記ベース10の操作孔13および支持突部12aに、前記カード50の操作突起52および切り欠き部55をそれぞれ組み付けることができる。
As shown in FIG. 14, the card 50 has a shape that can be stored in the recess 12 of the base 10, and has an operation projection 52 protruding from the bottom surface of the insulating recess 51 provided in the front center. The insulating recess 51 has an outer dimension that can be fitted into the rectangular annular rib 13a of the base 10 (FIG. 4C). On the other hand, the card 50 has a pair of insulating ribs 53 and 53 projecting from the upper and lower edges of the back surface thereof, and a protrusion 54 that abuts a movable contact piece 62 described later on the same axis as the operation protrusion 52. Is provided. The insulating rib 53 is used to increase the insulation distance by partitioning the upper and lower edges of the movable contact piece 62 described later (FIG. 4C). Further, the card 50 is provided with a notch portion 55 fitted to the support protrusion 12a provided on the base 10 at one side edge portion thereof.
Therefore, the operation protrusion 52 and the notch 55 of the card 50 can be assembled to the operation hole 13 and the support protrusion 12a of the base 10, respectively.

接点機構部60は、図2,3に図示するように、可動接点端子61と、固定接点端子70とで構成されている。
前記可動接点端子61は、図15に図示するように、その側面縁部から側方に延在した可動接触片62の自由端部に可動接点63をカシメ固定してある。前記可動接触片62の基部のうち、その上方縁部に圧入用舌片64を切り起こしてある一方、その下方縁部から圧入用舌片66を切り起こしてあるとともに、端子部66を延在してある。前記端子部66はプレス加工で打ち抜いた折り曲げ代を2つ折り重ねるとともに、前記折り曲げ代の上端縁部を曲げ起こしてシール止め部67としてある。なお、前記可動接触片62は、その先端部の角部を切り落とし、後述する固定接点端子70とのベース10の内面を介した絶縁距離を長くすることにより、絶縁特性を高めてある。
As shown in FIGS. 2 and 3, the contact mechanism unit 60 includes a movable contact terminal 61 and a fixed contact terminal 70.
As shown in FIG. 15, the movable contact terminal 61 has a movable contact 63 fixed by caulking to a free end portion of a movable contact piece 62 extending laterally from a side edge thereof. While the press-fitting tongue piece 64 is cut and raised at the upper edge of the base of the movable contact piece 62, the press-fitting tongue piece 66 is cut and raised from the lower edge and the terminal portion 66 extends. It is. The terminal portion 66 has two folding margins punched out by press working and folds the upper edge of the bending margin to form a seal stopper 67. It should be noted that the movable contact piece 62 has an improved insulating characteristic by cutting off a corner portion of the tip portion and lengthening an insulation distance through an inner surface of the base 10 with a fixed contact terminal 70 described later.

そして、前記可動接点端子61の圧入用舌片64,65をベース10の圧入溝19a,19bに圧入するとともに、その端子部66の基部を前記ベース10の可動接点端子用切り欠き部18aに嵌合する。これにより、前記可動接点端子61のシール止め部67が前記切り欠き部18aを塞ぐ(図6B)一方、可動接触片62がカード50の突条54に当接する。   Then, the press-fitting tongue pieces 64 and 65 of the movable contact terminal 61 are press-fitted into the press-fitting grooves 19 a and 19 b of the base 10, and the base portion of the terminal portion 66 is fitted into the movable contact terminal notch portion 18 a of the base 10. Match. As a result, the seal stopper 67 of the movable contact terminal 61 closes the notch 18a (FIG. 6B), while the movable contact piece 62 contacts the protrusion 54 of the card 50.

固定接点端子70は、図16に図示するように、その側面縁部から側方に延在した固定接触片71の先端部に固定接点72をカシメ固定してある一方、その下方縁部から端子部73を延在するとともに、その両側縁部から圧入用リブ74,74を切り起こしてある。また、前記端子部73の基部の奥側にはシール止め部75を突き出し加工で設けてある。そして、前記固定接触片71は、その先端部を前記固定接点72の外周に沿う円弧形状とし、特に、その先端縁部を前記固定接点72と面一となるように切除してある。前記可動接点端子61とのベース10の内面を介した絶縁距離、および、コイル端子37,38との絶縁距離を長くし、絶縁特性を向上させるためである。   As shown in FIG. 16, the fixed contact terminal 70 has a fixed contact 72 caulked and fixed to the tip of a fixed contact piece 71 extending laterally from the side edge thereof, while the terminal from the lower edge thereof is fixed. The portion 73 extends, and press-fitting ribs 74 and 74 are cut and raised from both side edges. Further, a seal stopper 75 is provided on the back side of the base portion of the terminal portion 73 by a protruding process. The fixed contact piece 71 has an arcuate shape along the outer periphery of the fixed contact 72, and the edge of the fixed contact piece 71 is cut away so as to be flush with the fixed contact 72. This is because the insulation distance between the movable contact terminal 61 via the inner surface of the base 10 and the insulation distance between the coil terminals 37 and 38 are increased to improve the insulation characteristics.

そして、前記固定接点端子70の圧入用舌片74,74を前記ベース10の圧入溝19c,19cに圧入し、その上端部76を絶縁壁11に設けた位置決め段部17に位置決めするとともに、端子部73の基部を前記固定接点端子用切り欠き部18bに嵌合する。ついで、前記位置決め段部17に設けたシール溜め部17aにシール材(図示せず)を注入して固化させることにより、前記固定接点端子70がベース10に固定され、固定接点72が可動接点63に接離可能に対向する。
なお、通常、接点開閉に伴って発生する接点の磨耗粉がベースの内面に付着し、溜まることにより、固定接点と可動接点とが電気的に短絡しやすくなり、絶縁劣化する。これに対し、本願発明によれば、可動接触片62の先端部および固定接触片71の先端部を切除してある。このため、固定接点72とベース10(凹所12の内面)との絶縁距離、または、可動接点63とベース10(凹所12の内面)との絶縁距離を長くでき、絶縁劣化を防止できるという利点がある。
Then, the press-fitting tongue pieces 74 and 74 of the fixed contact terminal 70 are press-fitted into the press-fitting grooves 19 c and 19 c of the base 10, and the upper end portion 76 is positioned on the positioning step portion 17 provided on the insulating wall 11, The base of the portion 73 is fitted into the fixed contact terminal notch 18b. Next, a fixed member 70 is fixed to the base 10 and a fixed contact 72 is fixed to the movable contact 63 by injecting a sealant (not shown) into a seal reservoir 17a provided in the positioning step 17 and solidifying it. Opposite to and away from.
Normally, the contact wear powder generated when the contact is opened and closed adheres to the inner surface of the base and accumulates, whereby the fixed contact and the movable contact are easily short-circuited, resulting in deterioration of insulation. On the other hand, according to the present invention, the tip of the movable contact piece 62 and the tip of the fixed contact piece 71 are cut off. For this reason, the insulation distance between the fixed contact 72 and the base 10 (the inner surface of the recess 12) or the insulation distance between the movable contact 63 and the base 10 (the inner surface of the recess 12) can be increased, and insulation deterioration can be prevented. There are advantages.

ケース80は、図2,3に図示するように、前記ベース10に嵌合可能な箱形状を有し、その上面隅部に孔81を設けてある。また、ケース80は、図17に図示するように、その天井面隅部に、前記スプール21のテーパ部24a(図1)に当接して誤挿入を防止する位置決め用突条82を一体成形してある。さらに、前記ケース80は、その天井面の短辺側隅部に、成形時のゲートによる不具合を回避するための段部83を有している。   As shown in FIGS. 2 and 3, the case 80 has a box shape that can be fitted to the base 10, and has a hole 81 at a corner of the upper surface thereof. In addition, as shown in FIG. 17, the case 80 is integrally formed with positioning protrusions 82 at the corners of the ceiling surface to contact the taper portion 24a (FIG. 1) of the spool 21 and prevent erroneous insertion. It is. Further, the case 80 has a step portion 83 for avoiding problems caused by the gate at the time of molding at the corner on the short side of the ceiling surface.

そして、内部構成部品を組み付けたベース10にケース80を嵌合した後、前記ベース10の底面に図示しないシール材を注入,固化してシールする。ベース10にケース80を嵌合すると、固定接点端子70のシール止め部75がケース80の内側面近傍に位置する。このため、可動接点端子61に設けたシール止め部67および固定接点端子70に設けたシール止め部75がシール材の侵入を阻止し、動作不良,接触不良の発生を防止できる。
ついで、前記ケース80の孔81を熱封止することにより、組立作業が完了する。
Then, after fitting the case 80 to the base 10 to which the internal components are assembled, a sealing material (not shown) is injected and solidified on the bottom surface of the base 10 for sealing. When the case 80 is fitted to the base 10, the seal stopper 75 of the fixed contact terminal 70 is positioned near the inner surface of the case 80. For this reason, the seal stopper 67 provided on the movable contact terminal 61 and the seal stopper 75 provided on the fixed contact terminal 70 prevent the intrusion of the sealing material, thereby preventing the occurrence of malfunction and contact failure.
Subsequently, the hole 81 of the case 80 is heat sealed to complete the assembly operation.

次に、本発明に係る電磁継電器の動作について説明する。
電磁石部20のコイル39に電圧が印加されていない場合には、可動接触片62のバネ力でカード50が絶縁壁11側に付勢されており、可動接点63が固定接点72から開離している一方、可動鉄片40の回動腕部44の先端部44aが門型鉄芯30から離れている(図13A)。
Next, the operation of the electromagnetic relay according to the present invention will be described.
When no voltage is applied to the coil 39 of the electromagnet unit 20, the card 50 is biased toward the insulating wall 11 by the spring force of the movable contact piece 62, and the movable contact 63 is separated from the fixed contact 72. On the other hand, the tip 44a of the rotating arm 44 of the movable iron piece 40 is separated from the portal iron core 30 (FIG. 13A).

そして、前記電磁石部20のコイル39に電圧を印加して励磁すると、可動鉄片40の回動腕部44の先端部44aが吸引され、軸部41,42を中心として可動鉄片40が回動する。そして、前記回動腕部44が押圧ポイントPでカード50の操作突起52を押し込むと(図13B)、軸部41と押圧ポイントPとを結ぶ線を中心とする捩りモーメントが作用する。このため、軸部42が門型鉄芯30から離れるとともに、可動鉄片40の先端部44aから延在した延在部47の先端縁部が門型鉄芯30に接近する(図13C)。ついで、延在部47の先端縁部が門型鉄芯30に吸着して安定状態となる(図13D)。この結果、カード50が最終位置まで押し込まれ、板厚方向に変位した可動接触片62の可動接点63が固定接点72に接触する。   When a voltage is applied to the coil 39 of the electromagnet portion 20 to excite it, the distal end portion 44a of the rotating arm portion 44 of the movable iron piece 40 is attracted, and the movable iron piece 40 rotates about the shaft portions 41 and 42. . When the rotating arm portion 44 pushes the operation protrusion 52 of the card 50 at the pressing point P (FIG. 13B), a torsional moment about the line connecting the shaft portion 41 and the pressing point P acts. For this reason, while the axial part 42 leaves | separates from the portal iron core 30, the front-end edge part of the extension part 47 extended from the front-end | tip part 44a of the movable iron piece 40 approaches the portal iron core 30 (FIG. 13C). Next, the leading edge of the extending portion 47 is attracted to the portal iron core 30 to be in a stable state (FIG. 13D). As a result, the card 50 is pushed to the final position, and the movable contact 63 of the movable contact piece 62 displaced in the plate thickness direction comes into contact with the fixed contact 72.

本実施形態では、門型鉄芯30の脚部32の下方側に磁束密度低減手段である浅溝33を設けてあるので、磁気抵抗が大きくなり、磁束密度が低下する。このため、可動鉄片40に捩りモーメントが作用すると、可動鉄片40の軸部42がストロークの初期段階で門型鉄芯30から離れる。この結果、動作電圧にバラツキがなくなり、安定した動作特性を有する電磁継電器が得られるという利点がある。
なお、磁束密度を低減させる手段としては、浅溝33に限らず、例えば、突起を設けてもよく、あるいは、遮磁板、銅メッキ等の非磁性体で構成してもよい。
また、磁束密度を低減させる手段は、前記門型鉄芯30および前記可動鉄片40の両方、または、いずれか一方に設けてもよい。
さらに、磁束密度を低減させる手段は、前述の浅溝、突起、遮磁板、非磁性体を組み合わせてもよく、例えば、門型鉄芯30に浅溝33と非磁性体とを設けて構成してもよい。
In this embodiment, since the shallow groove 33 which is a magnetic flux density reduction means is provided on the lower side of the leg portion 32 of the portal iron core 30, the magnetic resistance increases and the magnetic flux density decreases. For this reason, when a torsional moment acts on the movable iron piece 40, the shaft part 42 of the movable iron piece 40 moves away from the portal iron core 30 at the initial stage of the stroke. As a result, there is an advantage that there is no variation in the operating voltage and an electromagnetic relay having stable operating characteristics can be obtained.
The means for reducing the magnetic flux density is not limited to the shallow groove 33, and for example, a protrusion may be provided, or a nonmagnetic material such as a magnetic shielding plate or copper plating may be used.
Further, the means for reducing the magnetic flux density may be provided in both or either one of the portal iron core 30 and the movable iron piece 40.
Further, the means for reducing the magnetic flux density may be a combination of the above-mentioned shallow grooves, protrusions, magnetic shielding plates, and nonmagnetic materials. For example, the gate-type iron core 30 is provided with the shallow grooves 33 and nonmagnetic materials. May be.

ついで、前記コイル39の電圧の印加を停止すると、可動接触片62のバネ力により、カード50が押し戻され、カード50の操作突起52が可動鉄片40の回動腕部44を押し戻すことにより、元の状態に復帰する。   Next, when the application of the voltage of the coil 39 is stopped, the card 50 is pushed back by the spring force of the movable contact piece 62, and the operation protrusion 52 of the card 50 pushes back the rotating arm portion 44 of the movable iron piece 40, Return to the state.

次に、本発明に係るコイル端子37(図18参照)の製造装置90を説明する。なお、コイル端子38も同様に製造できるので、コイル端子37の製造のみについて説明する。   Next, the manufacturing apparatus 90 of the coil terminal 37 (refer FIG. 18) which concerns on this invention is demonstrated. In addition, since the coil terminal 38 can be manufactured similarly, only manufacture of the coil terminal 37 is demonstrated.

製造装置90は、図19ないし図21に示すように、基台131に、コイル端子37となる金属製線材95を挿通して保持する保持部132と、水平面成形ユニット91と、鉛直面成形ユニット92とからなる。鉛直面成形ユニット92は、水平面成形ユニット91が配置された取付溝134の底面と直交する取付壁135に配置されている。製造装置90は金属製線材95を鉛直方向から加工すると共に、水平方向からも加工する。   As shown in FIGS. 19 to 21, the manufacturing apparatus 90 includes a holding portion 132 for inserting and holding a metal wire 95 serving as the coil terminal 37 in the base 131, a horizontal surface forming unit 91, and a vertical surface forming unit. 92. The vertical surface forming unit 92 is disposed on an attachment wall 135 orthogonal to the bottom surface of the attachment groove 134 in which the horizontal surface forming unit 91 is disposed.

Further, U-shaped groove portions 106 and 106 for guiding the metal wire 95 are formed on the same straight line on both sides of the fixing through hole 105 of the guide groove 103.

パンチ受け金具111は、図24(A)および図24(B)に示すように、鉛直方向に延在した略長方形断面の本体112からなる。本体112には、その上端部に、幅方向に延在し、かつ、上方に突出する加工面113と、本体112の側面114上縁から前記加工面113まで傾斜して延び、加工面113に関して非対称の傾斜面115a,115bとが形成されている。傾斜面115a,115bが非対称に形成されることで、パンチ受け金具111が支持台102の固定用貫通孔105に誤挿入されるのを防止している。   As shown in FIGS. 24 (A) and 24 (B), the punch bracket 111 includes a main body 112 having a substantially rectangular cross section extending in the vertical direction. The main body 112 has, at its upper end, a processing surface 113 extending in the width direction and protruding upward, and an inclined surface extending from the upper edge of the side surface 114 of the main body 112 to the processing surface 113. Asymmetric inclined surfaces 115a and 115b are formed. By forming the inclined surfaces 115 a and 115 b asymmetrically, the punch receiving bracket 111 is prevented from being erroneously inserted into the fixing through hole 105 of the support base 102.

成形用パンチ121は、図25(A)および図25(B)に示すように、端部がドーム状に形成された円柱形の把持部122と、把持部122に連結し、かつ、略直方体形状のパンチ部123とを備えている。パンチ部123は、前記把持部122と反対側に位置する下端面に、中央に突出し、かつ、幅方向に延びる加工面124と、加工面124の両側に幅方向に延在したスリット125と、が形成されている。   As shown in FIGS. 25 (A) and 25 (B), the molding punch 121 is connected to the cylindrical gripping part 122 whose end is formed in a dome shape, the gripping part 122, and a substantially rectangular parallelepiped. And a punch portion 123 having a shape. The punch portion 123 has a processing surface 124 that protrudes in the center and extends in the width direction on the lower end surface located on the opposite side of the grip portion 122, and slits 125 that extend in the width direction on both sides of the processing surface 124. Is formed.

前記製造装置90で金属製線材95を形成するため、図19に示すように、金属製線材95を保持部132で保持し、水平面成形ユニット91で金属製線材95を鉛直方向から加工する。   In order to form the metal wire 95 by the manufacturing apparatus 90, the metal wire 95 is held by the holding part 132 and the metal wire 95 is processed from the vertical direction by the horizontal plane forming unit 91 as shown in FIG.

そして、図19中矢印方向に前記加工部分を鉛直面成形ユニット92のパンチ受け金具111および成形用パンチ121まで搬送して、水平方向から加工する。このため、金属製線材95を回転させる必要が無く、連続して効率よく金属製線材95を製造できる。この後、プレス機(図示せず)でプレスすることにより回り止め部37bを形成し、切断することによりコイル端子37,38が完成する。   And the said process part is conveyed to the punch receiving metal fitting 111 and the shaping | molding punch 121 of the vertical surface shaping | molding unit 92 in the arrow direction in FIG. 19, and is processed from a horizontal direction. For this reason, it is not necessary to rotate the metal wire 95, and the metal wire 95 can be manufactured continuously and efficiently. Thereafter, the rotation preventing portion 37b is formed by pressing with a press machine (not shown), and the coil terminals 37 and 38 are completed by cutting.

なお、前述の製造装置90では直交する方向に配置した水平面成形ユニット91、鉛直面成形ユニット92の順で金属製線材95を形成したが、これに限定されず、鉛直面成形ユニット92、水平面成形ユニット91の順で金属製線材95を形成してもよい。   In the manufacturing apparatus 90 described above, the metal wire 95 is formed in the order of the horizontal plane forming unit 91 and the vertical plane forming unit 92 arranged in the orthogonal direction. However, the present invention is not limited to this, and the vertical plane forming unit 92 and horizontal plane forming are not limited thereto. The metal wire 95 may be formed in the order of the unit 91.

製造装置90の変形例として、例えば図22(A)に示すように、鉛直方向から金属製線材95を加工する水平面成形ユニット91だけを用いてもよい。このとき、支持台102の案内用溝103に金属製線材95を設置し、支持台102の両側で金属製線材95を保持する。そして、パンチ受け金具111上にある金属製線材95を成形用パンチ121で上方から押圧し、パンチ受け金具111の加工面113と形成用パンチ121の加工面124とで金属製線材95を加工する。   As a modification of the manufacturing apparatus 90, for example, as shown in FIG. 22A, only a horizontal plane forming unit 91 that processes the metal wire 95 from the vertical direction may be used. At this time, the metal wire 95 is installed in the guide groove 103 of the support base 102, and the metal wire 95 is held on both sides of the support base 102. Then, the metal wire 95 on the punch receiving metal 111 is pressed from above by the forming punch 121, and the metal wire 95 is processed by the processing surface 113 of the punch receiving metal 111 and the processing surface 124 of the forming punch 121. .

次に、金属製線材95を90度回転させた後に、同様に金属製線材95を押圧する。2方向から金属製線材95を加工することで、端部が正方形断面の金属製線材95が得られる。この後、プレス機(図示せず)でプレス加工することにより回り止め部37bを形成する。
従って、本実施形態によれば、床面積の小さい小型の製造装置90が得られる。
Next, after rotating the metal wire 95 by 90 degrees, the metal wire 95 is pressed similarly. By processing the metal wire 95 from two directions, the metal wire 95 having a square cross section at the end can be obtained. Thereafter, the rotation preventing portion 37b is formed by pressing with a press machine (not shown).
Therefore, according to this embodiment, the small manufacturing apparatus 90 with a small floor area is obtained.

製造装置90の更なる変形例として、例えば図22(B)に示すように、水平方向から金属製線材95を加工する鉛直面成形ユニット92だけを用いて、前述と同様、金属製線材95を90度回しても、同様にコイル端子37が得られる。   As a further modification of the manufacturing apparatus 90, for example, as shown in FIG. 22B, only the vertical surface forming unit 92 that processes the metal wire 95 from the horizontal direction is used. Even when rotated 90 degrees, the coil terminal 37 is obtained in the same manner.

本願発明に係るコイル端子は電磁継電器に限らす、コイルを用いた他の電磁石部にも適用できるのは勿論である。   Of course, the coil terminal according to the present invention is not limited to the electromagnetic relay, and can be applied to other electromagnet parts using coils.
