Description

本発明は、電線を弾性保持する電磁接触器などの電気機器の接続構造に関する。   The present invention relates to a connection structure for an electric device such as an electromagnetic contactor that elastically holds an electric wire.

近年、電磁接触器などの電気機器では、電線を弾性保持する弾性部材を備えたスプリング端子が採用されてきている（例えば、特許文献１）。
特許文献１のスプリング端子は、電気機器のケース内に設けた電線挿入空間と、この電線挿入空間に連通するケースに設けた電線挿入口と、ケース内に配置され、電線挿入口から電線挿入空間に挿通された電線が電気的に接続される接点部を有する固定接触子と、電線挿入空間に配置され、電線挿入口から挿通された電線を弾性力で接点部側に押し付ける弾性部材と、を備えている。 In recent years, a spring terminal including an elastic member that elastically holds an electric wire has been adopted in an electric device such as an electromagnetic contactor (for example, Patent Document 1).
The spring terminal of Patent Document 1 is arranged in the case, the wire insertion space provided in the case of the electric device, the wire insertion port provided in the case communicating with the wire insertion space, and the wire insertion space from the wire insertion port. A fixed contact having a contact portion to which the electric wire inserted into the wire is electrically connected, and an elastic member disposed in the electric wire insertion space and pressing the electric wire inserted from the electric wire insertion port toward the contact portion with an elastic force. I have.

弾性部材は、金属板を曲げて形成した部材であり、平板状の固定部と、固定部の端部から円弧状に折り曲げた曲げ部を介して形成された平板状の電線保持部とで構成されている。
この弾性部材は、ケース内に固定部を固定し、電線保持部が、ケース内の電線挿入口の開口部近くを横切り、その先端が固定接触子の接点部に対向するように配置される。
そして、電線挿入口から挿入された電線が、固定接触子の接点部と弾性部材の電線保持部との間に入りこむと、曲げ部の弾性変形による弾性力によって、電線保持部の先端が電線を接点部側に押し付けて弾性保持する。 The elastic member is a member formed by bending a metal plate, and is composed of a flat plate-like fixing portion and a flat wire holding portion formed through a bent portion bent in an arc shape from the end of the fixing portion.

The elastic member fixes the fixing portion in the case, and the electric wire holding portion is disposed so as to cross the vicinity of the opening portion of the electric wire insertion opening in the case, and the tip thereof faces the contact portion of the fixed contact.
When the electric wire inserted from the electric wire insertion port enters between the contact portion of the fixed contact and the electric wire holding portion of the elastic member, the tip of the electric wire holding portion pulls the electric wire by the elastic force due to the elastic deformation of the bending portion. Press against the contact side and hold elastically.

次に、第１実施形態の電磁接触器１の作用効果について説明する。なお、複数対の電線挿入空間１０ａ〜１０ｂにスプリング端子２０（弾性部材２１及び固定接触子１５の接点部１５ｄ）が配置されているので、以下では一対の電線挿入空間１０ａの一方に配置されているスプリング端子２０の作用効果を説明する。
第１実施形態の電磁接触器１は、分割電線保持部２６ａの先端と接点部１５ｄとの間で弾性保持される芯線が、例えば図７の符号Ｗ１ａ、Ｗ１ｂで示すように、分割電線保持部２６ａの幅方向の縁に寄った状態で保持されたとしても、分割電線保持部２６ａの先端にはセンタリング部２７が形成されており、芯線Ｗ１ａ、Ｗ１ｂは、幅方向中央が最も凹んでいる円弧形状の切り欠きに沿って先端の幅方向中央位置（芯線Ｗ１の位置）まで移動していく。
したがって、第１実施形態の電磁接触器１は、分割電線保持部２６ａにセンタリング部２７を形成したことで、芯線Ｗ１が分割電線保持部２６ａの幅方向の端部側に移動するのを防止することができ、導電不良や電線Ｗが脱落するおそれがない。 Next, the effect of the electromagnetic contactor 1 of 1st Embodiment is demonstrated. In addition, since the spring terminal 20 (the elastic member 21 and the contact portion 15d of the fixed contact 15) is disposed in the plurality of pairs of wire insertion spaces 10a to 10b, the spring terminals 20 are disposed in one of the pair of wire insertion spaces 10a below.

The magnetic contactor 1 according to the first embodiment is configured such that the core wire elastically held between the tip of the divided wire holding portion 26a and the contact portion 15d is, for example, as indicated by reference characters W1a and W1b in FIG. Even if it is held close to the edge in the width direction of 26a, a centering portion 27 is formed at the tip of the split wire holding portion 26a, and the core wires W1a and W1b are arcs that are most concave in the center in the width direction. It moves to the center position in the width direction (position of the core wire W1) along the notch of the shape.
Therefore, the magnetic contactor 1 of 1st Embodiment prevents the core wire W1 moving to the edge part side of the width direction of the division | segmentation electric wire holding | maintenance part 26a by forming the centering part 27 in the division | segmentation electric wire holding | maintenance part 26a. There is no risk of poor electrical conductivity or the wire W dropping off.
