後者の圧接コネクタは電線保持部材の押し下げによりワンタッチで接続できるので使い勝手が良いが、電線の挿入においては片手で電線保持部材を所要角度に固定し、残った手で電線を挿入しなくてはならないので作業性が悪く、圧接コネクタの取り付け方向によっては手を差し入れることが難しい場合もあり、この問題が顕在化した。 The latter pressure connector is easy to use because it can be connected with one touch by pushing down the wire holding member, but when inserting the wire, the wire holding member must be fixed at the required angle with one hand and the wire must be inserted with the remaining hand. Therefore, workability is poor, and it may be difficult to insert a hand depending on the mounting direction of the pressure contact connector, and this problem has become apparent.

この考案は以上の従来技術の問題点を解消する圧接端子を提供することを目的として創作されたものであり、圧接端子を上向きに設けたハウジングと、ハウジングに対し回動自在に設けられると共に一端に設けた電線挿入孔から内部に電線を挿入することにより電線を保持する電線保持部材からなり、ハウジングに対する電線保持部材の押し下げにより電線保持部材に保持された被覆電線を圧接端子のＵ字状スロットに圧入して導通を図る圧接端子において、回動途中においてハウジングに対して電線保持部材を仮固定する手段を設けたことを特徴とする。 This device was created for the purpose of providing a pressure contact terminal that solves the above-mentioned problems of the prior art. The housing is provided with a pressure contact terminal facing upward, and is rotatably provided with respect to the housing. It consists of a wire holding member that holds the wire by inserting the wire into the inside from the wire insertion hole provided in the cover, and the covered wire held by the wire holding member by pushing down the wire holding member against the housing In the press contact terminal for press-fitting into the housing, means for temporarily fixing the wire holding member to the housing during rotation is provided.

よって、この考案によれば電線保持部材は所定の角度で仮固定されるので、電線の挿入を片手で行なうことができ、圧接コネクタの取り付け方向によって接続作業が阻害されることが防止される。又、端子数が多い場合でも電線保持部材は所定の角度で仮固定されているので電線を順次挿入する作業を容易に行なうことができる。 Therefore, according to this device, since the electric wire holding member is temporarily fixed at a predetermined angle, the electric wire can be inserted with one hand, and the connection work is prevented from being hindered by the mounting direction of the pressure contact connector. Even when the number of terminals is large, the wire holding member is temporarily fixed at a predetermined angle, so that the operation of sequentially inserting the wires can be easily performed.

以下、この考案の具体的実施例を添付図面に基づいて説明する。図１乃至図１９はこの考案の圧接コネクタの実施例を示す図である。この考案の圧接コネクタは圧接端子２０Ａ（２０Ｂ）を上向きに設けたハウジング１と、ハウジングに対し回動自在に設けられる電線保持部材１０からなり、ここでは２端子を備えるコネクタを例示している。 Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. 1 to 19 are views showing an embodiment of a pressure contact connector of the present invention. The pressure contact connector of the present invention includes a housing 1 having pressure contact terminals 20A (20B) facing upward, and an electric wire holding member 10 that is rotatably provided with respect to the housing. Here, a connector having two terminals is illustrated.

電線保持部材１０は幅方向両端に突設した軸ピン１１、１１をハウジング１の両側壁２、２に設けた軸孔３、３に挿入することにより、ハウジングとの枢支手段としている。又、電線保持部材１０の前端に垂設される前面板１２の下方に設けた掛止穴１６を、押し下げ完了時にハウジング１の前端に突設した掛止突起４に弾性掛止させることにより両者の回動固定手段としている。 The electric wire holding member 10 serves as a pivotal support means for the housing by inserting shaft pins 11, 11 protruding at both ends in the width direction into shaft holes 3, 3 provided on both side walls 2, 2 of the housing 1. Further, the latching hole 16 provided below the front plate 12 suspended from the front end of the electric wire holding member 10 is elastically latched by the latching projection 4 projecting from the front end of the housing 1 when the push-down is completed. The rotation fixing means.

電線保持部材１０は前面板１２から後端にかけて電線挿入孔１３Ａ（１３Ｂ）を貫通させることにより被覆した電線Ｌの保持手段としており、上記電線挿入孔の中途箇所に電線保持部材の下端に開口する切り欠き溝部１４Ａ（１４Ｂ）を介在させることにより圧接端子２０Ａ（２０Ｂ）の進入箇所としている（特に図５乃至図８参照）。又、上記切り欠き溝部１４Ａ（１４Ｂ）の底部にして挿入された電線Ｌが位置する箇所には、電線に接する高さ及び圧接端子２０Ａ（２０Ｂ）のＵ字状スロット２１Ａ（２１Ｂ）に挿通可能な幅を有するリブ１７Ａ（１７Ｂ）を突設して電線を当接させることにより、圧入時に電線が上方向に湾曲することを防止している（特に図６乃至図８参照）。 The electric wire holding member 10 serves as a holding means for the covered electric wire L by passing through the electric wire insertion hole 13A (13B) from the front plate 12 to the rear end, and opens at the lower end of the electric wire holding member in the middle of the electric wire insertion hole. The notch groove portion 14A (14B) is interposed so that the pressure contact terminal 20A (20B) enters (particularly, see FIGS. 5 to 8). Further, at the position where the electric wire L inserted at the bottom of the notch groove portion 14A (14B) is located, the height contacting the electric wire and the U-shaped slot 21A (21B) of the press contact terminal 20A (20B) can be inserted. By projecting ribs 17A (17B) having a wide width to bring the electric wires into contact with each other, the electric wires are prevented from bending upward during press-fitting (particularly, see FIGS. 6 to 8).

ハウジング１に立設される圧接端子２０Ａ（２０Ｂ）は、金属板の上端に電線Ｌの圧入後、更にそれが下降する程度の深さを有するＵ字状スロット２１Ａ（２１Ｂ）を設けた構成よりなる。ここではＵ字状スロット２１Ａ、２１Ｂの両側面と開口部を鋭利な接触刃に形成することにより、圧入時の電線Ｌの被覆部分の切り込みに要する抵抗を軽減し、圧入によるＵ字状スロットの変形を抑えている。これにより、例えば大径の電線を挿入した後に小径の電線を挿入しても、Ｕ字状スロットが広がり変形していないので接続に支障を来さず、異なる芯線径に対応可能な圧接コネクタが実現される。 The press contact terminal 20A (20B) erected on the housing 1 has a configuration in which a U-shaped slot 21A (21B) having a depth to which the electric wire L is further lowered after being press-fitted into the upper end of the metal plate is provided. Become. Here, by forming both side surfaces and openings of the U-shaped slots 21A and 21B into sharp contact blades, the resistance required to cut the covered portion of the electric wire L during press-fitting is reduced, and the U-shaped slots of the press-fitted by the press-fitting are reduced. Deformation is suppressed. Thus, for example, even if a small-diameter electric wire is inserted after inserting a large-diameter electric wire, the U-shaped slot does not expand and is not deformed. Realized.

そして、ここでは、回動に伴い電線保持部材１０の幅方向両端に突設したノッチ爪１５、１５を、ハウジング１の両側壁２、２の上端に設けた複数のノッチ５Ａ、５Ｂに順次弾性的に係止させることによりハウジングに対して電線保持部材を所定の角度（ここでは９０°と４５°）で仮固定するようにしており（図１１乃至図１３参照）、これがこの考案の特徴部分となる。尚、仮固定手段はこれに限らず、他の手段を採用してもよいことは勿論である。 In this case, the notch claws 15 and 15 projecting from both ends in the width direction of the electric wire holding member 10 in accordance with the rotation are sequentially elastically applied to the plurality of notches 5A and 5B provided at the upper ends of the side walls 2 and 2 of the housing 1. The electric wire holding member is temporarily fixed to the housing at predetermined angles (here, 90 ° and 45 °) (see FIGS. 11 to 13), which is a characteristic part of the present invention. It becomes. Needless to say, the temporary fixing means is not limited to this, and other means may be adopted.

又、この実施例では、電線Ｌの挿入具合を視認できるように電線保持部材１０を透明素材により構成している。この考案の圧接コネクタにおいては前記したように電線の挿入において電線保持部材を片手で支える必要が無い。よって、電線保持部材を遮るものはなく、電線保持部材を透明化すれば電線の挿入具合を容易に視認することができる。又、作業環境が薄暗い場合には開いた方で懐中電灯を用いて上記挿入具合を視認することも可能となる。 In this embodiment, the wire holding member 10 is made of a transparent material so that the insertion state of the wire L can be visually recognized. In the pressure contact connector of this device, as described above, it is not necessary to support the wire holding member with one hand when inserting the wire. Therefore, there is nothing to block the electric wire holding member, and if the electric wire holding member is made transparent, the insertion state of the electric wire can be easily visually confirmed. In addition, when the work environment is dim, it is possible to visually check the insertion condition using a flashlight when the work environment is open.

以上の実施例においては、図に示すように各圧接端子２０Ａ（２０Ｂ）の前後位置及びそれに対応する切り欠き溝部１４Ａ（１４Ｂ）を電線保持部材１０の回動の支点である軸ピン１１、１１に対しずらすことにより、各圧接端子と各電線との組ごとの圧入タイミングを電線保持部材の押し下げ角度に同期してずらしている。図１４乃至図１９はその詳細を示す図である。ここでは、圧接端子２０Ａ及びそれに対応する切り欠き溝部１４Ａを、同じく圧接端子２０Ｂ及び切り欠き溝部１４Ｂに対して回動の支点より遠い位置にずらしている。その結果、電線保持部材１０の押し下げに伴い、先ず支点に近い側の圧接端子２０Ｂと電線Ｌの組が圧入ポイントに差しかかり、その後支点から遠い側の圧接端子２０Ａと電線Ｌの組が圧入ポイントに差しかかることになる。この場合、前記したように電線保持部材の押し下げに要する力は電線の被覆部分が切り込まれ電線がスロット内に完全に挟まる圧入ポイントにおいて最大となり、その後の押し下げに際しては緩和されるので、支点から遠い側の圧接端子２０Ａと電線Ｌの組が圧入ポイントに差しかかる時点では、支点に近い側の圧接端子２０Ｂと電線Ｌの組は既に圧入ポイントを通過しているので、押し下げに要する力が一時に加重されることなく、少ない押し下げ力で圧接が実現される。 In the above embodiment, as shown in the figure, the front and rear positions of the respective press contact terminals 20A (20B) and the notch grooves 14A (14B) corresponding thereto are shaft pins 11, 11 which are pivots of the electric wire holding member 10. The press-fitting timing for each set of each press contact terminal and each electric wire is shifted in synchronization with the push-down angle of the electric wire holding member. FIG. 14 to FIG. 19 are diagrams showing the details. Here, the press contact terminal 20A and the notch groove portion 14A corresponding to the press contact terminal 20A are also shifted to positions far from the pivot point of rotation with respect to the press contact terminal 20B and the notch groove portion 14B. As a result, as the electric wire holding member 10 is pushed down, the pair of the press contact terminal 20B and the electric wire L on the side close to the fulcrum first hits the press fitting point, and then the set of the press contact terminal 20A and the electric wire L on the side far from the fulcrum becomes the press fit point. It will come soon. In this case, as described above, the force required to push down the electric wire holding member is maximized at the press-fitting point where the covered portion of the electric wire is cut and the electric wire is completely sandwiched in the slot. At the time when the pair of the press contact terminal 20A and the wire L on the far side reaches the press-fit point, the set of the press contact terminal 20B and the wire L on the side close to the fulcrum has already passed the press-fit point. The pressure welding is realized with a small pressing force without being sometimes loaded.
