実施の形態１．
図１は、この発明の実施の形態１に係る圧着工具におけるハンドルを開いた状態を示す正面図である。また、図２は、この発明の実施の形態１に係る圧着工具におけるハンドルを開いた状態を、圧着端子および電気配線とともに示す側面図である。 Embodiment 1.
FIG. 1 is a front view showing a state in which the handle of the crimping tool according to the first embodiment of the present invention is opened. Further, FIG. 2 is a side view showing a state in which the handle of the crimping tool according to the first embodiment of the present invention is opened, together with a crimping terminal and electrical wiring.

図１および図２において、圧着工具１０は、圧着端子である閉端接続子１と電気配線２とを圧着接続する工具である。また、圧着工具１０は、回転軸１１を介して回動可能に支持された一対のハンドル１２と、ハンドル１２の端部に接続され、ハンドル１２を閉じることにより、ハンドル１２とは反対側に設けられたかしめ部１３が閉じて、閉端接続子１をかしめて電気配線２と圧着接続する作動片１４を備えている。 In FIGS. 1 and 2, the crimping tool 10 is a tool for crimping and connecting the closed end connector 1 which is a crimping terminal and the electric wiring 2. Further, the crimping tool 10 is connected to a pair of handles 12 rotatably supported via a rotating shaft 11 and an end portion of the handles 12, and is provided on the opposite side of the handles 12 by closing the handles 12. The crimped portion 13 is closed, and the working piece 14 for crimping and crimping the closed end connector 1 to the electrical wiring 2 is provided.

また、圧着工具１０は、回転軸１１と一体化された棒状部材１５に対して、作動片１４側および作動片１４とは反対側に回動可能に設けられ、電気配線２をまとめて保持する保持部１６と、ハンドル１２を閉じることにより、保持部１６を作動片１４側に移動させるとともに、ハンドル１２を開くことにより、保持部１６を作動片１４とは反対側に移動させる移動機構を備えている。 Further, the crimping tool 10 is rotatably provided on the working piece 14 side and the side opposite to the working piece 14 with respect to the rod-shaped member 15 integrated with the rotating shaft 11, and holds the electric wiring 2 together. A moving mechanism for moving the holding portion 16 to the working piece 14 side by closing the holding portion 16 and the handle 12 and moving the holding portion 16 to the opposite side to the working piece 14 by opening the handle 12 is provided. ing.

ここで、移動機構は、保持部１６の先端とハンドル１２とを接続し、棒状部材１５に設けられたガイド部１７、およびハンドル１２と作動片１４との接続箇所を経由して配線されたワイヤ１８である。なお、保持部１６は、例えばクリップ状の形状を有し、電気配線２を挟むことで、電気配線２を保持している。また、保持部１６は、電気配線２とともに、閉端接続子１をあわせて保持してもよい。また、ハンドル１２と作動片１４との接続箇所は、例えば中空状の軸によって形成されている。 Here, the moving mechanism is a wire that connects the tip of the holding portion 16 and the handle 12 and is wired via the guide portion 17 provided on the rod-shaped member 15 and the connection portion between the handle 12 and the operating piece 14. It is 18. The holding portion 16 has, for example, a clip-like shape, and holds the electric wiring 2 by sandwiching the electric wiring 2. Further, the holding portion 16 may hold the closed end connector 1 together with the electric wiring 2. Further, the connection portion between the handle 12 and the operating piece 14 is formed by, for example, a hollow shaft.

図３は、この発明の実施の形態１に係る圧着工具におけるハンドルを閉じた状態を示す正面図である。また、図４は、この発明の実施の形態１に係る圧着工具におけるハンドルを閉じた状態を示す側面図である。以下、図１〜図４を参照しながら、圧着工具１０の動作について説明する。 FIG. 3 is a front view showing a state in which the handle of the crimping tool according to the first embodiment of the present invention is closed. Further, FIG. 4 is a side view showing a state in which the handle of the crimping tool according to the first embodiment of the present invention is closed. Hereinafter, the operation of the crimping tool 10 will be described with reference to FIGS. 1 to 4.

まず、ハンドル１２が開いた状態では、保持部１６は紙面水平方向を向いている。このとき、ハンドル１２が閉じられると、ハンドル１２と作動片１４との接続箇所が外側に広がることにより、ワイヤ１８が外側に引っ張られる。そのため、ワイヤ１８の動きに伴って、保持部１６が紙面上方に持ち上げられる。 First, when the handle 12 is open, the holding portion 16 faces the horizontal direction of the paper surface. At this time, when the handle 12 is closed, the connection portion between the handle 12 and the operating piece 14 expands outward, so that the wire 18 is pulled outward. Therefore, as the wire 18 moves, the holding portion 16 is lifted above the paper surface.

これにより、保持部１６により電気配線２をまとめて保持し、閉端接続子１をかしめる力を利用して、電気配線２を作動片１４側に押し上げることができるので、圧着接続時に閉端接続子１から電気配線２が抜けてしまうことを防止することができる。 As a result, the electric wiring 2 is collectively held by the holding portion 16, and the electric wiring 2 can be pushed up toward the working piece 14 by using the force of crimping the closed end connector 1, so that the closed end is closed at the time of crimp connection. It is possible to prevent the electrical wiring 2 from being disconnected from the connector 1.

以上のように、実施の形態１によれば、回転軸を介して回動可能に支持された一対のハンドルと、ハンドルの端部に接続され、ハンドルを閉じることにより、ハンドルとは反対側に設けられたかしめ部が閉じて、圧着端子をかしめて電気配線と圧着接続する作動片と、電気配線をまとめて保持する保持部と、ハンドルを閉じることにより、保持部を作動片側に移動させるとともに、ハンドルを開くことにより、保持部を作動片とは反対側に移動させる移動機構と、を備えている。
また、移動機構は、保持部の先端とハンドルとを接続し、ハンドルと作動片との接続箇所を経由して配線されたワイヤである。
そのため、圧着端子と電気配線とを確実に圧着接続することができる。 As described above, according to the first embodiment, a pair of handles rotatably supported via a rotation shaft and a pair of handles connected to the end of the handles and closed to the opposite side of the handles. By closing the provided caulking part, the working piece that crimps and connects the crimp terminal to the electrical wiring, the holding part that holds the electrical wiring together, and the handle, the holding part is moved to the working side. It is provided with a moving mechanism that moves the holding portion to the side opposite to the working piece by opening the handle.
Further, the moving mechanism is a wire that connects the tip of the holding portion and the handle and is wired via the connection portion between the handle and the working piece.
Therefore, the crimp terminal and the electric wiring can be securely crimped and connected.

実施の形態２．
この発明の実施の形態２では、実施の形態１とは異なる移動機構を有する圧着工具１０Ａについて説明する。図５は、この発明の実施の形態２に係る圧着工具におけるハンドルを開いた状態を示す側面図である。 Embodiment 2.
In the second embodiment of the present invention, the crimping tool 10A having a moving mechanism different from that of the first embodiment will be described. FIG. 5 is a side view showing a state in which the handle of the crimping tool according to the second embodiment of the present invention is opened.

図５において、圧着工具１０Ａは、回転軸１１と一体化された棒状部材１９に固定され、棒状部材１９とともに作動片１４側および作動片１４とは反対側に移動可能に設けられ、電気配線２をまとめて保持する保持部１６と、ハンドル１２を閉じることにより、保持部１６を作動片１４側に移動させるとともに、ハンドル１２を開くことにより、保持部１６を作動片１４とは反対側に移動させる移動機構を備えている。 In FIG. 5, the crimping tool 10A is fixed to a rod-shaped member 19 integrated with the rotating shaft 11 and is movably provided together with the rod-shaped member 19 on the working piece 14 side and the side opposite to the working piece 14, and the electrical wiring 2 The holding portion 16 and the handle 12 are closed to move the holding portion 16 to the operating piece 14 side, and the handle 12 is opened to move the holding portion 16 to the opposite side to the operating piece 14. It is equipped with a moving mechanism to make it move.

ここで、移動機構は、回転軸１１と一体化され、ハンドル１２の開閉に合わせて作動片１４側または作動片１４とは反対側に移動するための溝が形成された棒状部材１９である。なお、棒状部材１９に形成された溝の角度により、移動量を調整することができる。 Here, the moving mechanism is a rod-shaped member 19 that is integrated with the rotating shaft 11 and has a groove formed for moving to the working piece 14 side or the side opposite to the working piece 14 according to the opening and closing of the handle 12. The amount of movement can be adjusted by the angle of the groove formed in the rod-shaped member 19.

図６は、この発明の実施の形態２に係る圧着工具におけるハンドルを閉じた状態を示す側面図である。以下、図５、図６を参照しながら、圧着工具１０Ａの動作について説明する。 FIG. 6 is a side view showing a state in which the handle of the crimping tool according to the second embodiment of the present invention is closed. Hereinafter, the operation of the crimping tool 10A will be described with reference to FIGS. 5 and 6.

まず、ハンドル１２が開いた状態では、保持部１６は作動片１４から離れた位置にある。このとき、ハンドル１２が閉じられると、回転軸１１と一体化された棒状部材１９が回転することにより、棒状部材１９および棒状部材１９に固定された保持部１６が紙面上方に持ち上げられる。 First, when the handle 12 is open, the holding portion 16 is located at a position away from the operating piece 14. At this time, when the handle 12 is closed, the rod-shaped member 19 integrated with the rotating shaft 11 rotates, so that the rod-shaped member 19 and the holding portion 16 fixed to the rod-shaped member 19 are lifted above the paper surface.

これにより、保持部１６により電気配線２をまとめて保持し、閉端接続子１をかしめる力を利用して、電気配線２を作動片１４側に押し上げることができるので、圧着接続時に閉端接続子１から電気配線２が抜けてしまうことを防止することができる。 As a result, the electric wiring 2 is collectively held by the holding portion 16, and the electric wiring 2 can be pushed up toward the working piece 14 by using the force of crimping the closed end connector 1, so that the closed end is closed at the time of crimp connection. It is possible to prevent the electrical wiring 2 from being disconnected from the connector 1.

なお、保持部１６を棒状部材１９に固定した場合には、閉端接続子１と電気配線２との位置関係によっては、電気配線２が必要以上に作動片１４側に押し上げられる可能性がある。そこで、保持部１６の作動片１４側への移動を、あらかじめ定められた範囲に規制する規制部材を設けることが考えられる。 When the holding portion 16 is fixed to the rod-shaped member 19, the electric wiring 2 may be pushed up toward the operating piece 14 more than necessary depending on the positional relationship between the closed end connector 1 and the electric wiring 2. .. Therefore, it is conceivable to provide a regulating member that regulates the movement of the holding portion 16 toward the operating piece 14 within a predetermined range.

図７は、この発明の実施の形態２に係る圧着工具を示す別の側面図である。図７において、保持部１６は、棒状部材１９ではなく、規制部材である支持部材２０に、同じく規制部材であるばね２１を介して接続され、支持部材２０が、棒状部材１９に固定されている。これにより、保持部１６の過剰な移動量が規制部材に吸収されるので、保持部１６の作動片１４側への移動を、あらかじめ定められた範囲に規制することができる。 FIG. 7 is another side view showing the crimping tool according to the second embodiment of the present invention. In FIG. 7, the holding portion 16 is connected not to the rod-shaped member 19 but to the supporting member 20 which is a regulating member via a spring 21 which is also a regulating member, and the supporting member 20 is fixed to the rod-shaped member 19. .. As a result, the excessive movement amount of the holding portion 16 is absorbed by the regulating member, so that the movement of the holding portion 16 toward the operating piece 14 can be regulated within a predetermined range.

以上のように、実施の形態２によれば、回転軸を介して回動可能に支持された一対のハンドルと、ハンドルの端部に接続され、ハンドルを閉じることにより、ハンドルとは反対側に設けられたかしめ部が閉じて、圧着端子をかしめて電気配線と圧着接続する作動片と、電気配線をまとめて保持する保持部と、ハンドルを閉じることにより、保持部を作動片側に移動させるとともに、ハンドルを開くことにより、保持部を作動片とは反対側に移動させる移動機構と、を備えている。
また、移動機構は、回転軸と一体化され、ハンドルの開閉に合わせて作動片側または作動片とは反対側に移動するための溝が形成された棒状部材である。
そのため、圧着端子と電気配線とを確実に圧着接続することができる。 As described above, according to the second embodiment, a pair of handles rotatably supported via a rotation shaft and a pair of handles connected to the end of the handles and closed to the opposite side of the handles. By closing the provided caulking part, the working piece that crimps and connects the crimp terminal to the electrical wiring, the holding part that holds the electrical wiring together, and the handle, the holding part is moved to the working side. It is provided with a moving mechanism that moves the holding portion to the side opposite to the working piece by opening the handle.
Further, the moving mechanism is a rod-shaped member integrated with the rotating shaft and formed with a groove for moving to one side of the working piece or the side opposite to the working piece according to the opening and closing of the handle.
Therefore, the crimp terminal and the electric wiring can be securely crimped and connected.

なお、上記の各実施の形態では、閉端接続子１を用いて圧着接続する場合について説明するが、左右からの配線を圧着端子で接続する場合等、閉端接続子以外の部材を圧着接続するものであってもよい。 In each of the above embodiments, the case of crimp connection using the closed end connector 1 will be described, but a member other than the closed end connector is crimped and connected, such as when the wiring from the left and right is connected by the crimp terminal. It may be something to do.
