ケーブル用圧着端子Crimp terminal for cable
　本発明は、電気工事や電気通信工事などの施工に用いられるケーブル用圧着端子に関する。 The present invention relates to a crimp terminal for a cable used for construction such as electrical work and telecommunications work.
　電気通信設備などの導体にケーブルを電気的に接続するために、ケーブルの先端に圧着端子が取り付けられる。圧着端子は、導体とボルトで固定するための穴が開いた部分である導体接続部と、導体接続部をケーブルに接続するための配線接続部とで構成される。従来の圧着端子は、導体接続部と配線接続部が一体成型されており、圧着端子に可動部を有さない（特許文献１参照）。 In order to electrically connect the cable to a conductor such as a telecommunication facility, a crimp terminal is attached to the end of the cable. The crimp terminal includes a conductor connection portion that is a portion in which a hole for fixing with a conductor and a bolt is opened, and a wiring connection portion for connecting the conductor connection portion to a cable.

However, if there is a moving part in the crimp terminal, there is a risk that the crimp terminal or cable will come into contact with the housing, etc. due to vibration of the telecommunication equipment where the crimp terminal is attached or external force applied to the cable. is there.
　本発明は、配線接続の施工性を向上させつつ、圧着端子や筐体の破損を低減することを目的とする。 The present invention has an object of reducing breakage of a crimp terminal and a casing while improving workability of wiring connection.

　可動部固定用カバー２４１には可動部２２１にかぶせるための切り込みなどがあり、可動部２２１に任意の長さの可動部固定用カバー２４１をかぶせることで、可動部２２１の可動領域の長さが調整できる。可動部固定用カバー２４１は、配線接続部２３１側に装着されてもよく、導体接続部２１１側に装着されてもよく、中間の位置に装着されてもよい。いずれの場合でも、可動部固定用カバー２４１が装着された部分の可動範囲は制限される。可動部固定用カバー２４１の長さが短いほど可動範囲は大きくなり、可動部固定用カバー２４１の長さが長いほど可動範囲は小さくなる。このように、可動部固定用カバー２４１を用いることで、可動部２２１の可動範囲を制限できる。 The movable part fixing cover 241 has a cut or the like for covering the movable part 221. By covering the movable part 221 with the movable part fixing cover 241 of any length, the length of the movable region of the movable part 221 is increased. Can be adjusted. The movable portion fixing cover 241 may be attached to the wiring connection portion 231 side, may be attached to the conductor connection portion 211 side, or may be attached to an intermediate position. In any case, the movable range of the portion where the movable portion fixing cover 241 is attached is limited. The movable range becomes larger as the length of the movable portion fixing cover 241 becomes shorter, and the movable range becomes smaller as the length of the movable portion fixing cover 241 becomes longer. Thus, by using the movable part fixing cover 241, the movable range of the movable part 221 can be limited.
　図３は、可動部固定用カバー２４１が装着されていないときの可動範囲を示す図である。図３（ａ）は側面から見たときの可動範囲を示しており、図３（ｂ）は正面から見たときの可動範囲を示している。 FIG. 3 is a diagram showing a movable range when the movable part fixing cover 241 is not attached. FIG. 3A shows the movable range when viewed from the side, and FIG. 3B shows the movable range when viewed from the front.
　可動部２２１の可動範囲は、可とう導体の強度、大きさなどに依存して決まり、図３（ａ）に示すように角度αから角度βまで上下方向に大きく回動し、図３（ｂ）に示すように角度θから角度φまで横方向に大きく回動する。 The movable range of the movable portion 221 is determined depending on the strength, size, and the like of the flexible conductor, and as shown in FIG. As shown in FIG. 2), it is pivoted horizontally from angle θ to angle φ.
　図４は、可動部固定用カバー２４１が装着されたときの可動範囲を示す図である。図４（ａ）は側面から見たときの可動範囲を示しており、図４（ｂ）は正面から見たときの可動範囲を示している。 FIG. 4 is a diagram showing a movable range when the movable part fixing cover 241 is attached. FIG. 4A shows the movable range when viewed from the side, and FIG. 4B shows the movable range when viewed from the front.
　可動部固定用カバー２４１が装着されると、可動部固定用カバー２４１の部分の動きは制限され、上下方向の可動範囲は、角度αから角度βまでの範囲よりも小さい角度α'から角度β'までの範囲になる。同様に、横方向の可動範囲も、角度θから角度φまでの範囲よりも小さい角度θ'から角度φ'までの範囲になる。α'、β'、θ'、φ'は可動部固定用カバー２４１の長さを変えることで調整可能である。 When the movable portion fixing cover 241 is attached, the movement of the portion of the movable portion fixing cover 241 is limited, and the movable range in the vertical direction is smaller than the range from the angle α to the angle β, from the angle α ′ to the angle β. The range is up to '. Similarly, the movable range in the lateral direction is also a range from the angle θ ′ to the angle φ ′ that is smaller than the range from the angle θ to the angle φ. α ′, β ′, θ ′, and φ ′ can be adjusted by changing the length of the movable portion fixing cover 241.
　図５は、可動部ロック用カバー２４２を装着する様子を示す図である。図５（ａ）は可動部ロック用カバー２４２を装着する前の図であり、図５（ｂ）は可動部ロック用カバー２４２を装着した後の図である。 FIG. 5 is a diagram showing a state in which the movable part locking cover 242 is mounted. FIG. 5A is a diagram before the movable portion locking cover 242 is mounted, and FIG. 5B is a diagram after the movable portion locking cover 242 is mounted.
　可動部固定用カバー２４１で覆われていない可動部２２１の部分に可動部ロック用カバー２４２をかぶせることで、可動部２２１が可動部固定用カバー２４１と可動部ロック用カバー２４２で覆われることになる。その結果、可動部２２１が固定される。 The movable part 221 is covered with the movable part fixing cover 241 and the movable part locking cover 242 by covering the part of the movable part 221 not covered with the movable part fixing cover 241 with the movable part locking cover 242. Become. As a result, the movable part 221 is fixed.
　上記のように、実施例１の首振り型圧着端子２００には可動部２２１が存在するため、電気工事や電気通信工事などにおいて配線接続の位置調整にかかる時間を削減することができ、施工性を向上させることができる。可動部２２１の動きによって配線接続時に不要な力が加わらないため、配線接続時に圧着端子や筐体が破損するリスクを低減できる。また、可動部固定用カバー２４１が存在するため、可動部２２１の可動範囲が制限され、圧着端子やケーブルが筐体などに接触して短絡する状況を軽減することができる。さらに、可動部ロック用カバー２４２が存在するため、施工後に可動部２２１が固定され、圧着端子やケーブルが筐体などに接触して短絡する状況を回避することができる。 As described above, since the movable portion 221 is present in the swing-type crimp terminal 200 of the first embodiment, it is possible to reduce the time required for adjusting the position of the wiring connection in electrical work or telecommunications work, and the workability is improved. Can be improved. Since unnecessary force is not applied at the time of wiring connection due to the movement of the movable portion 221, it is possible to reduce the risk of damage to the crimp terminal or the housing at the time of wiring connection. In addition, since the movable portion fixing cover 241 exists, the movable range of the movable portion 221 is limited, and the situation where the crimp terminal or the cable comes into contact with the housing or the like and is short-circuited can be reduced. Furthermore, since the movable part locking cover 242 exists, the movable part 221 is fixed after the construction, and a situation in which the crimp terminal or the cable comes into contact with the housing or the like and is short-circuited can be avoided.

　図６は、本発明の実施例２に係る首振り型圧着端子１００の正面図及び斜視図である。図６（ａ）は首振り型圧着端子１００の正面図であり、図６（ｂ）は首振り型圧着端子１００の斜視図である。 <Example 2>
FIG. 6 is a front view and perspective view of a swing-type crimp terminal 100 according to the second embodiment of the present invention. 6A is a front view of the swing-type crimp terminal 100, and FIG. 6B is a perspective view of the swing-type crimp terminal 100.
　首振り型圧着端子１００は、電気通信設備などの導体と接続するための導体接続部１１１と、ケーブルに対する導体接続部１１１の角度を調整可能な可動部１２１と、圧着端子とケーブルを接続するための配線接続部１３１とで構成される。また、首振り型圧着端子１００は、可動部１２１の可動角度を固定するためのロック機構１４１を有する。 The swing-type crimp terminal 100 is connected to a conductor connecting portion 111 for connecting to a conductor such as telecommunication equipment, a movable portion 121 capable of adjusting the angle of the conductor connecting portion 111 with respect to the cable, and a crimp terminal to connect the cable. Wiring connection portion 131. Further, the swing-type crimp terminal 100 has a lock mechanism 141 for fixing the movable angle of the movable portion 121.
　導体接続部１１１と、可動部１２１と、配線接続部１３１は、導電性・不燃性のものとし、必要な電流を流せる断面積を有するものとする。例えば、銅などの金属とする。導体接続部１１１には、導体と接触させボルトなどで固定するための穴がある。 The conductor connecting portion 111, the movable portion 121, and the wiring connecting portion 131 are conductive and nonflammable and have a cross-sectional area through which a necessary current can flow. For example, a metal such as copper is used. The conductor connecting portion 111 has a hole for making contact with the conductor and fixing with a bolt or the like.
　可動部１２１は、ヒンジ機構とする。 The movable part 121 is a hinge mechanism.
　ロック機構１４１は、不燃性の素材とする。ロック機構１４１は導電性でもよく、導電性でなくてもよい。例えば、鉄など金属や、アクリル樹脂などの合成樹脂とする。ロック機構１４１については後述する。 The lock mechanism 141 is made of a nonflammable material. The lock mechanism 141 may be conductive or may not be conductive. For example, a metal such as iron or a synthetic resin such as acrylic resin is used. The lock mechanism 141 will be described later.
　図７は、可動部１２１の分解斜視図である。可動部１２１は、軸部１２１ａと軸受部１２１ｂとで構成される。図７（ａ）及び（ｂ）は軸受部１２１ｂを異なる角度から見たときの図であり、図７（ｃ）及び（ｄ）は軸部１２１ａを異なる角度から見たときの図である。 FIG. 7 is an exploded perspective view of the movable portion 121. The movable part 121 includes a shaft part 121a and a bearing part 121b. 7A and 7B are views when the bearing portion 121b is viewed from different angles, and FIGS. 7C and 7D are views when the shaft portion 121a is viewed from different angles.
　軸部１２１ａには突起部１２１ｌがあり、軸受部１２１ｂには溝部１２１ｍがあり、突起部１２１ｌは溝部１２１ｍの内部を通過する。なお、軸部１２１ａに溝部が設けられ、軸受部１２１ｂに突起部が設けられてもよい。いずれの場合でも、ヒンジ機構の軸部１２１ａ及び軸受部１２１ｂにそれぞれ設けられた突起部１２１ｌ及び溝部１２１ｍによって、可動部１２１の可動角度が制限される。溝部１２１ｍの長さが長いほど可動範囲は大きくなり、溝部１２１ｍの長さが短いほど可動範囲は小さくなる。このように、突起部１２１ｌ及び溝部１２１ｍを用いることで、可動部１２１の可動範囲を制限できる。 The shaft 121a has a protrusion 121l, the bearing 121b has a groove 121m, and the protrusion 121l passes through the groove 121m. In addition, a groove part may be provided in the shaft part 121a, and a protrusion part may be provided in the bearing part 121b. In any case, the movable angle of the movable portion 121 is limited by the protrusion 121l and the groove 121m provided on the shaft portion 121a and the bearing portion 121b of the hinge mechanism, respectively. The longer the length of the groove 121m, the larger the movable range, and the shorter the length of the groove 121m, the smaller the movable range. Thus, the movable range of the movable part 121 can be limited by using the protruding part 121l and the groove part 121m.
　軸部１２１ａ及び軸受部１２１ｂに設けられたロック機構の凹部１４１ｂ及び１４１ｂについては後述する。 The recesses 141b and 141b of the lock mechanism provided in the shaft part 121a and the bearing part 121b will be described later.
　図８は、軸部１２１ａ及び軸受部１２１ｂに突起部１２１ｌ及び溝部１２１ｍが存在しないときの可動範囲を示す図である。 FIG. 8 is a view showing a movable range when the projecting part 121l and the groove part 121m are not present in the shaft part 121a and the bearing part 121b.
　ヒンジ機構は、ヒンジの中心点を中心として角度αから角度βまで上下方向に大きく回動する。場合によっては導体接続部１１１が配線接続部１３１に接触するまで回動する。 The hinge mechanism is pivoted up and down from the angle α to the angle β around the center point of the hinge. In some cases, the conductor connection portion 111 rotates until it contacts the wiring connection portion 131.
　図９は、軸部１２１ａ及び軸受部１２１ｂに突起部１２１ｌ及び溝部１２１ｍが存在するときの可動範囲を示す図である。 FIG. 9 is a diagram showing a movable range when the projecting part 121l and the groove part 121m exist in the shaft part 121a and the bearing part 121b.
　突起部１２１ｌは溝部１２１ｍを超えて回動することはできないので、突起部１２１ｌ及び溝部１２１ｍによってヒンジ機構の可動範囲は制限され、上下方向の可動範囲は、角度αから角度βまでの範囲よりも小さい角度α'から角度β'までの範囲になる。角度α'から角度β'の範囲は、突起部１２１ｌの幅を無視すると、ヒンジの中心点を中心とする溝部１２１ｍの円周角である。すなわち、α'、β'は溝部１２１ｍの長さを変えることで調整可能である。 Since the protrusion 121l cannot rotate beyond the groove 121m, the movable range of the hinge mechanism is limited by the protrusion 121l and the groove 121m, and the vertical movable range is more than the range from the angle α to the angle β. The range is from a small angle α ′ to an angle β ′. The range from the angle α ′ to the angle β ′ is the circumferential angle of the groove 121m with the center point of the hinge as the center when the width of the protrusion 121l is ignored. That is, α ′ and β ′ can be adjusted by changing the length of the groove 121m.
　図１０は、ロック機構１４１の斜視図及び分解斜視図を示す図である。図１０（ａ）は軸部１２１ａと軸受部１２１ｂが結合しているときの図であり、図１０（ｂ）は軸部１２１ａと軸受部１２１ｂが分解されたときの図である。 FIG. 10 shows a perspective view and an exploded perspective view of the lock mechanism 141. 10A is a view when the shaft portion 121a and the bearing portion 121b are coupled, and FIG. 10B is a view when the shaft portion 121a and the bearing portion 121b are disassembled.
　ロック機構１４１は、スライドスイッチ１４１ａと、軸部１２１ａに設けられた凹部１４１ｂと、軸受部１２１ｂに設けられた凹部１４１ｃとで構成される。 The lock mechanism 141 includes a slide switch 141a, a concave portion 141b provided in the shaft portion 121a, and a concave portion 141c provided in the bearing portion 121b.
　図１１は、ロック機構１４１の動作を示す図である。図１１（ａ）に示すように、スライドスイッチ１４１ａが軸受部１２１ｂ側にある場合、ロックオフ状態であり、ヒンジ機構は回動可能である。しかし、図１１（ｂ）に示すように、軸部１２１ａの凹部１４１ｂと軸受部１２１ｂの凹部１４１ｃが並んだときに、スライドスイッチ１４１ａは軸部１２１ａ側にスライドすることができる。このとき、スライドスイッチ１４１ａによってヒンジが固定される。スライドスイッチ１４１ａがスライドできるときのヒンジの角度は予め設定した角度（例えば、図８及び図９における０°の角度、±６０°の角度など）とすることができる。 FIG. 11 is a diagram illustrating the operation of the lock mechanism 141. As shown to Fig.11 (a), when the slide switch 141a exists in the bearing part 121b side, it is a lock-off state and the hinge mechanism can be rotated. However, as shown in FIG. 11B, when the concave portion 141b of the shaft portion 121a and the concave portion 141c of the bearing portion 121b are aligned, the slide switch 141a can slide to the shaft portion 121a side. At this time, the hinge is fixed by the slide switch 141a. The angle of the hinge when the slide switch 141a can slide can be set to a preset angle (for example, an angle of 0 ° or an angle of ± 60 ° in FIGS. 8 and 9).
　上記のように、実施例２の首振り型圧着端子１００には可動部１２１が存在するため、電気工事や電気通信工事などにおいて配線接続の位置調整にかかる時間を削減することができ、施工性を向上させることができる。可動部１２１の動きによって配線接続時に不要な力が加わらないため、配線接続時に圧着端子や筐体が破損するリスクを低減できる。また、軸部１２１ａ及び軸受部１２１ｂに突起部１２１ｌ及び溝部１２１ｍが存在するため、可動部１２１の可動範囲が制限され、圧着端子やケーブルが筐体などに接触して短絡する状況を軽減することができる。さらに、ロック機構１４１が存在するため、施工後に可動部１２１が固定され、圧着端子やケーブルが筐体などに接触して短絡する状況を回避することができる。 As described above, since the movable part 121 is present in the swing-type crimp terminal 100 of the second embodiment, it is possible to reduce the time required for the position adjustment of the wiring connection in electrical work or telecommunication work, and the workability is improved. Can be improved. Since unnecessary force is not applied at the time of wiring connection due to the movement of the movable portion 121, the risk of damage to the crimp terminal or the housing at the time of wiring connection can be reduced. In addition, since the projection 1211 and the groove 121m are present on the shaft 121a and the bearing 121b, the movable range of the movable part 121 is limited, and the situation where the crimp terminal or the cable contacts the housing or the like is short-circuited is reduced. Can do. Furthermore, since the lock mechanism 141 exists, the movable part 121 is fixed after construction, and a situation in which a crimp terminal or a cable comes into contact with a housing or the like and is short-circuited can be avoided.
　以上、配線接続の施工性を向上させつつ、圧着端子や筐体の破損を低減するための手法について説明したが、本発明は、上記の実施例に限定されることなく、特許請求の範囲内において、種々の変更・応用が可能である。 As described above, the method for reducing breakage of the crimp terminal and the housing while improving the workability of the wiring connection has been described, but the present invention is not limited to the above-described embodiments, and is within the scope of the claims. Various changes and applications can be made.
