由DE 10 2011 056 410 A1已知一種槓桿操作式終端線夾，其具有構建為扭轉彈簧的，用於將***終端線夾之電導線夾緊至電流條的夾箍彈簧。用於操縱夾箍彈簧的操縱元件具有一旋轉軸，其係橫向於對應之導線插口中之導線***方向，或橫向於導線插口之沿導線***方向延伸至接線點的延長部佈置。透過將旋轉軸佈設在接線點之區域內，或者與前方之導線插口對齊，以相對接近操縱元件之旋轉軸的方式操縱夾箍彈簧，從而減小作動於終端線夾之殼體的槓桿力。A lever-operated terminal clamp is known from DE 10 2011 056 410 A1, which has a clamp spring which is designed as a torsion spring and is used to clamp an electrical conductor inserted into the terminal clamp to a current bar. The operating element for operating the clamp spring has a rotation axis, which is arranged transversely to the wire insertion direction in the corresponding wire socket, or is arranged to extend to the connection point in the wire insertion direction transversely to the wire socket. By arranging the rotation shaft in the area of the connection point or aligning with the front wire socket, the clamp spring is operated relatively close to the rotation axis of the operating element, thereby reducing the lever force acting on the housing of the terminal clamp.
本發明之目的在於提供一種終端線夾，藉由該終端線夾能夠將在夾緊導線時作動於殼體之力進一步減小。 本發明用以達成上述目的之解決方案為獨立項之特徵。本發明之較佳設計方案及有利改進方案參閱附屬項。 本發明之終端線夾的特徵在於，該操縱元件具有軸體，以供該操縱元件圍繞偏轉，其中在該夾箍彈簧之保持邊腳上設有容置裝置，以將該軸體旋轉式支承於其中。 確切言之，根據本發明，該操縱元件係直接設於該夾箍彈簧之保持邊腳上，不同於夾箍彈簧之夾腳，該保持邊腳係以位置固定的方式定位在該終端線夾中，特別是該終端線夾之殼體中。其中該保持邊腳較佳平面式地抵靠在該殼體上，特別是平面式地抵靠在界定殼體之內腔的內壁上。該操縱元件係藉由其軸體支承在該夾箍彈簧之保持邊腳上，故操縱元件之穿過軸體延伸的旋轉軸定位在該夾箍彈簧之區域內。為將操縱元件或操縱元件之軸體支承在夾箍彈簧上，在該夾箍彈簧上設有一容置裝置，軸體係可旋轉式定位在該容置裝置中。該容置裝置較佳直接成型於該夾箍彈簧之保持邊腳上。該容置裝置較佳與該保持邊腳一體成型，故該容置裝置係自該夾箍彈簧之金屬帶彎曲加工出。透過將操縱元件直接支承在夾箍彈簧之保持邊腳上，能夠將在夾緊導線時作動於殼體之力大幅減小，具體方式為，可將由操縱元件施加至夾箍彈簧的用於操縱夾箍彈簧的力保持在夾箍彈簧內。 為能將該操縱元件之軸體可靠地旋轉式支承在該容置裝置中，較佳地，該容置裝置呈U形並且至少部分將該軸體包圍。該容置裝置之形狀較佳與軸體之外輪廓匹配，從而在操縱元件之偏轉運動期間在容置裝置內實現對軸體的最佳導引。 該夾箍彈簧較佳採用如下設計方案：該保持邊腳具有開口，其被該電流條之自由端穿過，並且可供待連接之導線穿過。該開口較佳構建為窗格狀開口，並且既用於供電流條穿過，亦用於供待連接之導線穿過。由於電流條與待連接之導線皆穿過電流條之開口，藉此亦能使在將導線夾緊至電流條時產生的力傳遞至保持邊腳以及傳遞至夾箍彈簧，從而藉由夾箍彈簧將此等力吸收，進而最大程度地避免夾緊力傳遞至終端線夾之殼體。藉此將在夾緊導線時作動於殼體之力進一步減小。 該容置裝置較佳以位於該開口上方，以及位於穿過該開口之電流條上方的方式設於該夾箍彈簧之保持邊腳上。藉由容置裝置、電流條及開口之上述相對彼此的定位，能夠以節省空間的方式將各部件佈置在該終端線夾內，從而減小終端線夾之結構尺寸。 還可藉由以下方案減小該終端線夾之結構尺寸：該夾腳係成型於該保持邊腳之第一自由端上，以及，該容置裝置係設於保持邊腳之與該第一自由端相對的第二自由端上。在保持邊腳之該二自由端之間，在該保持邊腳中構建有開口。該夾腳在保持邊腳上之佈局以及該容置裝置在保持邊腳上之佈局較佳設於該保持邊腳之同一縱側面上，並且設於該朝向殼體之內腔及終端線夾之內腔的縱側面上，在該內腔中將導線連接或夾緊至電流條。 該夾箍彈簧之夾腳較佳如下成型：此夾腳具有抵靠區域，並藉此抵靠在該保持邊腳之一縱側面上，使得在夾腳進入夾箍彈簧之開啟位置及閉合位置的運動中，此夾腳係可沿保持邊腳之縱側面移動。因此，在操縱該夾箍彈簧時，夾腳之一部分能夠沿保持邊腳滑動，從而藉由保持邊腳實現對夾腳的既定導引。 較佳地，該夾腳不呈直線形，而是呈S形。透過該夾腳之S形能夠增大待藉由夾腳施加的夾緊力，而不增大夾箍彈簧之總尺寸，特別是寬度。此外還能改善夾腳之彈簧效果。 為構成S形，該夾腳可具有與該保持邊腳連接之第一偏轉區段，透過彎曲接頭與該第一偏轉區段連接之第二偏轉區段，以及透過該抵靠區域與該第二偏轉區段連接之夾緊區段。該二偏轉區段以及該夾緊區段較佳呈直線形，而該彎曲接頭以及該抵靠區域較佳係彎曲。該二偏轉區段較佳具有相同的長度，而該夾緊區段較佳具有大幅減小之長度。該夾緊區段之長度例如約為偏轉區段之長度的三分之一。該二偏轉區段與該保持邊腳較佳一起構成Δ形。較佳透過該二偏轉區段實現該夾腳之彈簧效果，其中該等偏轉區段係以與待連接之導線間隔一定距離的方式佈置。透過該夾腳之夾緊區段來連接或夾緊導線。 該操縱元件較佳採用如下設計方案：此操縱元件具有第一操縱片以及與其平行的第二操縱片，其用於操縱該夾箍彈簧，其中該軸體較佳設於該第一操縱片與該第二操縱片之間。該等操縱片呈長條形，並且自軸體出發延伸至夾箍彈簧之夾腳，其中為操縱夾箍彈簧，操縱片藉由操縱元件之偏轉運動壓向夾腳並藉此對其施力。由於兩個相互平行之操縱片在操縱過程中同時壓向夾腳，能夠在夾腳之寬度範圍內實現均勻的力分佈，其中能夠避免操縱元件及/或夾箍彈簧在夾箍彈簧之操縱過程中傾斜。此外，由於該軸體係設於該二操縱片之間，該等操縱片能夠實現軸體在容置裝置中的鎖緊，因為操縱片防止軸體側向自容置裝置滑出。 在該夾箍彈簧之操縱過程中，該等操縱片較佳不直接壓向該夾腳之夾緊區段，進而不壓向該夾腳之與經夾緊之導線直接接觸的部分，而是較佳與夾箍彈簧之不與待連接之導線直接接觸的第二偏轉區段作用性連接，以對夾箍彈簧進行操縱。藉此，由於操縱元件或操縱元件之軸體與操縱元件在夾箍彈簧之夾腳上之作用點之間的槓桿臂延長，能夠將待由操作人員施加至操縱元件的用於操縱夾箍彈簧的力大幅減小，從而增強終端線夾之操作人員的操作舒適性。It is an object of the present invention to provide a terminal clamp, which can further reduce the force acting on the housing when clamping the wire. The solution of the present invention to achieve the above-mentioned object is a feature of independent items. For the preferred design scheme and advantageous improvement scheme of the present invention, refer to the appended items. The terminal clamp of the present invention is characterized in that the operating element has a shaft body for the operating element to deflect around, wherein a holding device is provided on a holding leg of the clamp spring to rotatably support the shaft body In it. Specifically, according to the present invention, the operating element is directly provided on the retaining leg of the clamp spring, and unlike the clamping leg of the clamp spring, the retaining leg is positioned on the terminal clamp in a fixed manner. Medium, especially in the housing of the terminal clamp. Wherein, the holding leg is preferably abutted flatly against the casing, especially abutted flatly against an inner wall defining an inner cavity of the casing. The operating element is supported on the retaining leg of the clamp spring by its shaft body, so the rotation axis of the operating element extending through the shaft body is positioned in the region of the clamp spring. In order to support the operating element or the shaft of the operating element on a clamp spring, an accommodating device is provided on the clamp spring, and the shaft system is rotatably positioned in the accommodating device. The accommodating device is preferably formed directly on the retaining leg of the clamp spring. The accommodating device is preferably integrally formed with the retaining leg, so the accommodating device is formed by bending the metal band of the clamp spring. By directly supporting the operating element on the retaining leg of the clamp spring, the force acting on the housing when the wire is clamped can be greatly reduced. Specifically, the operating force applied to the clamping spring by the operating element for the clamping spring can be reduced. The force of the clamp spring is held within the clamp spring. In order to enable the shaft body of the operating element to be reliably and rotatably supported in the accommodation device, preferably, the accommodation device is U-shaped and at least partially surrounds the shaft body. The shape of the accommodating device preferably matches the contour outside the shaft body, so that the shaft body is optimally guided during the deflection movement of the operating element. The clamp spring preferably adopts the following design scheme: the holding leg has an opening, which is passed by the free end of the current bar, and can be passed by the wire to be connected. The opening is preferably constructed as a pane-shaped opening and is used for both the current bar and the wire to be connected. Since both the current bar and the wire to be connected pass through the opening of the current bar, the force generated when the wire is clamped to the current bar can also be transmitted to the holding leg and to the clamp spring, so as to pass the clamp The spring absorbs these forces, thereby preventing the clamping force from being transmitted to the housing of the terminal clamp to the greatest extent. As a result, the force acting on the housing when the wire is clamped is further reduced. The accommodating device is preferably provided on the retaining leg of the clamp spring in a manner above the opening and above the current bar passing through the opening. By positioning the above-mentioned relative to each other of the accommodating device, the current bar, and the opening, each component can be arranged in the terminal clamp in a space-saving manner, thereby reducing the structural size of the terminal clamp. The structure size of the terminal clamp can also be reduced by the following schemes: the clamp foot is formed on the first free end of the retaining leg, and the receiving device is disposed between the retaining leg and the first The free end is opposite the second free end. An opening is formed in the holding leg between the two free ends of the holding leg. The layout of the clamping leg on the holding leg and the arrangement of the accommodating device on the holding leg are preferably provided on the same longitudinal side of the holding leg, and are provided on the inner cavity facing the housing and the terminal clip. On the longitudinal side of the inner cavity, a wire is connected or clamped to the current bar in the inner cavity. The clamping leg of the clamp spring is preferably formed as follows: the clamping leg has an abutment area and thereby abuts on one of the longitudinal sides of the retaining leg, so that the clamping leg enters the open position and the closed position of the clamping spring During the movement, the clip foot can be moved along the longitudinal side of the holding leg. Therefore, when the clamp spring is manipulated, a part of the clamp foot can slide along the retaining leg, so that the predetermined guide of the clamp foot is realized by the retaining leg. Preferably, the clip foot is not straight, but is S-shaped. The S-shape of the clamp foot can increase the clamping force to be applied by the clamp foot without increasing the overall size, especially the width, of the clamp spring. In addition, the spring effect of the clamp feet can be improved. To form an S-shape, the clip foot may have a first deflection section connected to the retaining leg, a second deflection section connected to the first deflection section through a curved joint, and a first deflection section connected to the first deflection section through the abutment area. Clamping section connected by two deflection sections. The two deflection sections and the clamping section are preferably linear, and the curved joint and the abutting area are preferably curved. The two deflection sections preferably have the same length, and the clamping section preferably has a substantially reduced length. The length of the clamping section is, for example, approximately one third of the length of the deflection section. The two deflection sections and the retaining leg preferably form a delta shape. The spring effect of the clip feet is preferably achieved through the two deflection sections, wherein the deflection sections are arranged at a distance from the wire to be connected. The wire is connected or clamped through the clamping section of the clamp foot. The control element preferably adopts the following design scheme: the control element has a first control piece and a second control piece parallel to the first control piece, and is used to control the clamp spring, wherein the shaft body is preferably provided between the first control piece and the first control piece; The second control piece. These control pieces are elongated and extend from the shaft body to the clamp feet of the clamp spring. Among them, the clamp spring is manipulated. The control piece is pressed against the clamp feet by the deflection movement of the control element and thereby exerts force on them. . Because two parallel control pieces are pressed toward the clamp feet at the same time during the operation, a uniform force distribution can be achieved within the width of the clamp feet, and the operation process of the control element and / or the clamp spring during the clamp spring can be avoided. Medium tilt. In addition, since the shaft system is disposed between the two manipulation pads, the manipulation pads can realize the locking of the shaft body in the accommodation device, because the manipulation pads prevent the shaft body from sliding out of the self-accommodation device laterally. During the operation of the clamp spring, the control pieces are preferably not directly pressed against the clamping section of the clamping foot, and then not to the part of the clamping foot directly contacting the clamped wire, but Preferably, it is operatively connected with the second deflection section of the clamp spring which is not in direct contact with the wire to be connected to manipulate the clamp spring. Thereby, since the lever arm between the operating element or the shaft body of the operating element and the point of action of the operating element on the clamping leg of the clamp spring is extended, it is possible to apply the operator to the operating element for operating the clamp spring. The force is greatly reduced, thereby enhancing the operating comfort of the operator of the terminal clamp.

The terminal clamp 100 has a casing 10 made of an insulating material, wherein the casing 10 has a wire socket 11 for inserting a conductor to be connected into the terminal clamp 100. A current bar 12 is provided in the casing 10, and the wires to be connected can be clamped to the current bar in an electrical contact manner. To clamp the wires to the current bar 12, the terminal clamp 100 has a clamp spring 13, which is disposed in the inner cavity 14 of the housing 10. The clamp spring 13 has a holding leg 15 and a clamping leg 17 connected to the holding leg 15 through a bent section 16. The retaining leg 15 bears against the inner wall 18 of the housing 10 at least partially in a planar manner, which inner wall defines the inner cavity 14 of the housing 10. The holding leg 15 is thereby provided in the housing 10 in a fixed position. Different from the retaining leg 15, the clamping leg 17 extends into the inner cavity 14 of the casing 10, wherein the clamping leg 17 is movable in the elastic cavity in the inner cavity 14 of the casing 10. The wire is clamped to the current bar 12 by the clamping feet 17. To operate the clamp spring 13 so that it enters the open position and / or the closed position, the terminal clamp 100 has an operating element 19 which is supported in a deflectable manner. The operating element 19 has a shaft body 20 in the form of a shaft, wherein the rotation axis of the operating element 19 extends through the shaft body 20, so the operating element 19 can be deflected around the shaft body 20. The shaft body 20 is supported in a receiving device 21 provided on the retaining leg 15 of the clamp spring 13. The shaft body 20 is thereby supported on the clamp spring 13 and is not directly supported on the housing 10. In this way, the force applied to the clamp spring 13 by the operating element 19 when the wire is clamped is held in the clamp spring 13, so that the force acting on the housing 10 is greatly reduced. FIG. 4 shows only the clamp spring 13 and the accommodating device 21 provided thereon, and other components of the terminal clip 100 are not shown. In the design scheme shown here, the accommodating device 21 is integrally formed with the clamp spring 13. Specifically, the accommodating device 21 is formed by bending the strip of the clamp spring 13. The width of the accommodating device 21 is slightly smaller than the holding leg 15. The accommodating device 21 is bent in a U-shaped or C-shaped manner, so the accommodating device 21 at least partially surrounds the shaft body 20 having a circular cross section. Therefore, the contour of the accommodating device 21 matches the contour of the shaft body 20. Below the connection of the accommodating device 21 on the holding leg 15, a pane-shaped opening 22 is constructed in the holding leg 15, which can be penetrated by the free end 37 of the current bar 12 as shown in FIGS. 1-3, And can be passed through the wire to be connected. The wire inserted into the inner cavity 14 of the casing 10 through the opening 22 is clamped to the first side 23 of the current bar 12 facing the inner cavity 14 of the casing 10 by the clamping leg 17 of the clamp spring 13. By opposing the first side surface 23 and facing away from the second side surface 24 of the inner cavity 14 of the housing 10, the current bar 12 abuts on the accommodation device 21, particularly against the outer surface of the accommodation device 21. . The accommodating device 21 and the clamping feet 17 of the clamp spring 13 are thereby separated from each other by the current bar 12. The opening 22 in the holding leg 15 is arranged in alignment with the wire socket 11 in the housing 10. In the design scheme shown here, the accommodating device 21 and the clamping leg 17 are arranged on the ends 36 and 25 of the holding leg 15 which are spaced apart from each other, so that the Maximize the distance. The clamping leg 17 is formed on the first free end 36 of the holding leg 15, and the accommodating device is disposed on the second free end 25 of the holding leg 15 opposite to the first free end 36. As shown in FIGS. 2 and 4, the width of the clamping leg 17 is smaller than the holding leg 15. The retaining leg 15 of the clamp spring 13 is linear. The clamp feet 17 of the clamp spring 13 are not linear. The clamp feet 17 are divided into several sections, which form an angle between 10 ° and 80 ° with each other. Therefore, the clamping leg 17 is S-shaped. Among them, the clamping leg 17 is shaped so as to have an abutment region 26 by which the clamping leg 17 abuts on the longitudinal side 27 of the holding leg 15 facing the inner cavity 14 of the housing 10 so that the clamping leg 17 When the foot 17 enters the open position and the closed position of the clamp spring 13, the clamp foot moves along the longitudinal side 27. This abutment region 26 is arched. To form an S-shape, the clamping leg 17 also has a first deflection section 28 connected to the retaining leg 15, a second deflection section 30 connected to the first deflection section 28 through a curved joint 29, and abutment areas A clamping section 31 connected to the second deflection section 30. The spring effect of the clip 17 is achieved by the two deflection sections 28, 30 which can move relative to each other through the curved joint 29. The two deflection sections 28, 30 have substantially the same length. The deflection sections 28, 30 form a delta shape together with a part of the holding section 15. A longitudinal slit 32 is formed in the second deflection section 30, which extends over the entire length of the deflection section 30. By providing the longitudinal slits 32 in the deflection section 30, the spring effect of the clip feet 17 can be enhanced. The conductor is clamped by the direct contact of the clamping section 31 of the clamping leg 17 with the conductor. The length of the clamping section 31 is much shorter than the deflection sections 28, 30. The length of the clamping section 31 is less than one third of the length of one of the deflection sections 28, 30. In the range of the two deflection sections 28, 30, the bending joint 29 and the abutment area 26, the width of the clamping leg 17 is constant, and the width of the clamping section 31 is reduced, which is further than that of the two deflection areas. The segments 28, 30, the curved joint 29 and the abutment area 26 are narrower. To operate the clamp spring 13, as shown in FIG. 2 in particular, the operating element 19 has a first operating piece 33 and a second operating piece 34 parallel to the operating piece 19, wherein the shaft body 20 is provided between the first operating piece 33 and the second operating piece. Piece 34. Starting from the shaft body 20, the two control pieces 33 and 34 protrude into the inner cavity 14 of the housing 10. The two control pieces 33 and 34 pass along the sides of the current bar 12 respectively, so that the current bar 12 is disposed between the two control pieces 33 and 34. The operating pieces 33 and 34 further loop the current bar 12. The operating pieces 33 and 34 have a specific length so as to be operatively connected to the second deflection section 30 of the clamp spring 13 and not operatively connected to the clamping section 31 to manipulate the clamp spring 13. During the movement of the clamp spring 13 or the terminal clamp 100 into the open position and the closed position, as shown in FIGS. 1 and 3, the manipulation pieces 33 and 34 move or move along the surface of the second deflection section 30. The operating element 19 also has a handle 35, and the operator of the terminal clamp 100 can hold the operating element 19 and deflect it. The handle of the operating element 19 protrudes from the housing 10. The handle 35, the shaft body 20, and the control pieces 33 and 34 are integrally connected.
