備えている。(Prior Art) Tools for easily and quickly connecting a plurality of electric wires to a U-shaped clip-shaped terminal are widely used for in-plant wiring of various electronic devices 1, such as electronic button telephones. This tool has the function of pushing the wire into the clip terminal, breaking the sheath at the U-shaped connection part to establish an electrical connection, and cutting off the unnecessary part of the wire once the connection is complete.

No. 53-14938, No. 55-43HO, No. 59-
No. 20788 etc. have been proposed. These tools all include a pusher for pressing the electric wire into the U-shaped connection part,
A cutter that cuts the entire length of the wire by pressing it against the insulating base of the clip terminal is fixed in parallel. Among the above tools, Jikosho 5
No. 9-20788 includes a guide plate having a wide recess on the end surface between the presser and the cutter.
このガイドプレートが押圧後退可能に構成されているが
、押圧子とカッタは固定されている。Although this guide plate is configured to be able to be pressed and retreated, the presser and cutter are fixed.
いずれにしても、上記各工具はカッタ刃が押圧子よりも
突出されており、この状態を図面第7図として図示する
。即ち、押圧子dとカッタeとは並設状態で位置固定さ
れており、電線Cの余長C。In any case, the cutter blade of each of the above-mentioned tools protrudes beyond the presser, and this state is illustrated in FIG. 7 of the drawings. That is, the presser d and the cutter e are arranged side by side and fixed in position, and the extra length C of the electric wire C.
をクリップ端子aの絶縁基台すに押付して切断できるた
めに押圧子dの押圧端面d°よりもカッタ eの刃先e
′が突出されていなければならない、その突出量は、少
なくとも電線径よりも大きく設定されている。The cutting edge e of the cutter e is lower than the pressing end surface d° of the presser d because it can be cut by pressing it against the insulating base of the clip terminal a.
' must be protruded, and the amount of protrusion is set to be at least larger than the diameter of the electric wire.
電線Cの接続に際して押圧子dとカッタeの双方で電線
を端子aのU字溝a゛に圧入し、電線Cが端子基台すに
当接して接続が完了してから更にカッタを前進させて電
線を切断する。When connecting the wire C, press the wire into the U-shaped groove a of the terminal a using both the presser d and the cutter e, and after the wire C contacts the terminal base and the connection is completed, move the cutter further forward. to cut the wire.
(発明が解決しようとする問題点) 上記構造によれば、カッタ刃先e゛が押圧端面d。(Problem to be solved by the invention) According to the above structure, the cutter blade edge e' is the pressing end surface d.
よりも突出する機構であるために、押圧に際してはカッ
タ刃先e°を利用して圧入することとなる欠点があった
。その結果、第一に、第7図(A)(B)のようにカッ
タ刃先e°の突出量だけ電11iICが軸線方向に曲げ

であった。第二に、電線が曲げられながらU字溝a°へ
圧入されるので、U字溝a′に対する圧入力が大きくな
って、押圧作業に際しての疲労が激しいものであった。Since the mechanism protrudes further than the cutter, there is a drawback that the cutter edge e° must be used for pressing. As a result, firstly, as shown in Fig. 7 (A) and (B), the electric 11i IC was bent in the axial direction by the amount of protrusion of the cutter blade edge e°, so that it could not be connected in a straight line in the axial direction. . Second, since the electric wire is press-fitted into the U-shaped groove a° while being bent, the pressing force against the U-shaped groove a' becomes large, resulting in severe fatigue during the pressing operation.
第三に、カッタ刃先e゛は、圧入力を大部分負押しなけ
ればならないために、摩耗が激しく、常に交換に迫られ
るものであった。Thirdly, the cutter edge e' is subject to severe wear because most of the pressing force has to be applied in the negative direction, so that it is constantly required to be replaced.
又、電線切断は、第7図(D)のように余長C′の機械

あった。Further, as shown in FIG. 7(D), the wire may be cut with a sufficient margin in consideration of the deterioration of the mechanical properties of the extra length C'. In this case, a gap f is formed between the pusher d of the wire C and the cutter e to maintain a cutting margin of extra length C°, so if the press-fitting load is large, the wire C will be press-fitted into the U-shaped groove a′. There was an accident in which the electric wire C entered the gap f without opening, resulting in a poor connection.

圧切断機構にある。(Means for Solving the Problems) The electric wire connecting tool for clip terminals according to the present invention to achieve the above object is characterized by a pusher for press-connecting an electric wire to a clip terminal having a substantially U-shape, and In a connection tool that is equipped with a cutter that is placed in parallel with the wire and presses the wire length against the insulating base of the clip terminal to cut it, the cutter is usually set back from the wire pressing surface of the pusher so that the pusher is pushed in at a constant rate. The pressure cutting mechanism is configured such that the cutter moves forward when the cutter reaches the end.

It is held in a straight line in the axial direction and pressed. When the pressing force of the presser reaches a certain amount and the electric wire is connected to the clip terminal, the cutter moves forward and cuts the extra length of the electric wire between it and the insulating base.

ている。The clip terminal connection tool 1 includes a presser 2 and a cutter 3 arranged in parallel so that they can move forward and backward. The presser 2 has pressing pieces 5, 5 protruding through the terminal allowing groove 4, and the pressing pieces 5, 5 are provided horizontally with wire holding grooves 6, B, which serve as wire pressing surfaces, respectively. Further, since the cutting edge 7 of the cutter 3 is normally set back from the wire pressing surface of the pusher, it is installed flush with or set back from the groove surface of the wire holding groove 8.8.

長C°を切断する。According to the above-mentioned electric wire connection tool l for clip terminals, while applying the electric wire C to the υ-shaped groove a° of the clip terminal d, the electric wire C is placed in the electric wire holding groove 8.8 in the axial direction and the pressure is set. . In this state, the electric wire C is held linearly in the axial direction by the horizontally provided electric wire holding groove 8.6. Since the wire is pressed by the pair of wire holding grooves 6, 6,
Even if there is pressing resistance to the U-shaped groove a°, it is pressed substantially horizontally. When the pressure of the pusher 2 reaches a certain amount, the wire coating becomes U.
When the electric wire is torn at the groove a° and connected to the clip terminal a, the cutting edge 7 of the cutter e moves forward and cuts the wire by an extra length C° between it and the insulating base.

カッタ3は案内部材12に固定されている。A guide member 12 inside the grippable elongated housing 11 houses a pusher 2 that is biased forward by an action member 13, and an impact member biased forward by a spring 14 at the rear thereof. 15 is housed within the guide member 12 in a regulated state by a shoulder portion 18. The operating member 13 is inserted through the coil spring 17 and is positioned in an inclined manner with its eccentric reduced diameter portion 17a, so that it is pressed into contact with the expanded diameter portion 18 of the pusher 2. Further, the impact member 17
A through hole 18 is bored along the axis of the. moreover,
The cutter 3 is fixed to a guide member 12.

に当接している電線余長C°を切断する。At the time of connection, when the housing 1 is pressed toward the insulating base, the wire C is inserted into the U-shaped groove a° with the sheath cut open. As a reaction to this, the presser 2 to the action member 1
3 retreats against the biasing force of the coil spring 17, and the impact member 15 also retreats against the spring 14. When the housing 1 is further pressed toward the insulating base, the posture of the circumferential side portion 13a of the first action member 13 is corrected by the inclined wall surface 18a of the shoulder portion IB of the guide member 12, so that the push shaft 13b of the action member 13 is corrected.
is aligned with the through hole 19 of the impact member 15. As a result, when the impact member 15 is released from the restraint of the action member 13, it moves forward at once due to the elastic force of the spring 14 and collides with the shoulder lB, and the impact impact at this time causes the cutting edge 7 of the cutter 3 to Cut the extra length C° of the wire that is in contact with the wire.
図示しないが、上記クリップ端子用電線接続工具の他の
押圧切断機構としては、押圧子2の後部をばねで付勢し

に設計できる。Although not shown, another pressing cutting mechanism of the wire connecting tool for clip terminals can be designed such that the rear part of the presser 2 is urged by a spring, and the cutter 3 moves forward as the presser 2 is pushed. .
又、電線保持溝B、Bが対構成されたものを図示説明し
たが、これらの間に溝面と同位置の電線押込片を配置す
