Description

  • The Invention relates to a terminal for connecting electrical conductors, comprising an electrically conductive frame part, in the further frame called, as well as a spring held in the frame. Usually These electrically conductive parts through an insulating housing surround.
  • To the Connection and tapping of electrical conductors already exist numerous terminals. These terminals are used for electrical contact a leader. On the other hand, the leader is using the clamp is held mechanically. This will be sufficient Guaranteed peel strength. That way, one becomes electrical connection between a conductor and an electronic component, such as, for example, an operating element of luminous bodies, guaranteed.
  • From the DE 202 05 665 U1 a connection terminal is known, consisting of a spring, a contact part, a lower housing part, an upper housing part and a pusher cap. The spring is configured spangenförmig. A first end leg of the spring has a window. A second end leg of the spring is orthogonal to the window. Parallel to the second end leg, the contact part extends and extends through the window, so that the spring biases the contact part in extension of an insertion opening of the housing against the window and thus forms a nip. To insert an electrical conductor, the pusher cap must be actuated, which relieves the clamping point and opens the window to the insertion opening. By relaxing the actuator, the electrical conductor is clamped between the spring and contact part and placed in a loaded state, so that the head is secure against jamming.
  • Consequently is for introducing flexible and rigid conductors the Operation of the pusher cap necessary to the Release opening. The preload force the spring manufactured as a stamped part thus loads when pressed the pusher cap on this. That leads to a high load on the housing parts, as it is the pusher cap, as with the other parts of the housing, to injection-molded parts is. Furthermore offers only the injection-molded housing via insertion opening a guide for the leader, which is why due to production engineering deviations during injection molding, the clamp a bad guide provides for the terminal point and positioning of the conductor.
  • From the DE 196 54 611 A1 is also known a connection terminal for electrical conductors, consisting of a busbar piece, comprising a holding leg and a contact leg, a spangenförmigen leaf spring and a Isolierstoffgehäuse and cover. In the holding leg a slot-shaped slot breakthrough, called in the further Hubschlitz, provided for each leaf spring. The Hubschlitz is formed by two mutually parallel side edges whose distance is greater than the width of the associated spring. The head ends of the spring is mounted in the upper end of the Hubschlitzes, while the foot of the spring extends in the conductor insertion through the Hubschlitz and forms a nip with the contact leg of the busbar piece. In addition, partitions between the clamping points are each formed of two sections, which are molded onto the housing part on the one hand and the housing cover on the other hand, so that the sections limit the holding leg of the busbar piece close to each other between them. Injection molding, in comparison to punching, is an inaccurate process. The injection molding of the partitions in retrospect can thus lead to uneven results with relatively large tolerances, so that jamming of individual wires of strands between spring and partitions can occur.
  • Accordingly It is an object of the invention to introduce electrical To facilitate conductors as well as jamming of individual wires one Wire between window and frame or spring to prevent.
  • These The object is achieved by the features of the independent claims protected. Make the dependent claims the central idea of the invention in particularly advantageous Continue.
  • According to one First aspect of the invention, the terminal for connecting electrical conductors a frame part, which is electrically conductive, and a spring, which is held in the frame part. A leg of the spring forms in an unloaded condition of the clamp, d. H. without inserted Ladder, with an insertion bevel of the frame part one to the conductor insertion direction open, V-shaped Angle forms. One end of the spring is one with at least three Formed sides of limited windows. The window extends from the spring leg. The angle is closed in the unloaded state, by biasing the edge of the window underside against the Insertion bevel presses and thus the nip forms.
  • According to a second aspect of the invention, the terminal for connecting electrical conductors comprises a frame part, which is electrically conductive, and a spring, which is held in the frame part. An upper end of the spring is formed with a window bounded on at least three sides. The window is supported on an upper portion of the frame part. The away from the window The lower end of the spring is supported on a lower portion of the frame member. The edge of the underside of the window presses under pretension against the upper region of the frame part and thus forms a nip. The window and the frame part are movable relative to each other.
  • According to one third aspect of the invention, the terminal for connection of electrical conductors a frame part, which is electrically conductive, and a spring held in the frame part. An end to the Spring is with a limited on at least three sides window educated. The end of the spring is further provided with a spring leg shaped, which with the window a V-shaped angle encloses and forms a nip with the frame.
  • The Clamp described here according to a first aspect the invention has an open to the conductor insertion direction, V-shaped angle formed on one leg of the Spring and an insertion bevel of the frame part. In this way, the insertion of an electrical conductor simplified because the conductor during insertion through the spring leg and the insertion bevel of the frame to the nip to be led. Furthermore, by the insertion bevel allows the leader to face the Feather safely supported and thus easily bend the spring can. Especially, but not exclusively with rigid Ladders it is therefore possible to jam this in the terminal, without additionally operating an actuator.
  • Of Further, one end of the spring is one on at least three sides formed limited window which extends from the spring leg. Since the window is formed in the spring, jamming, especially of single wires of a stranded wire, between windows or spring and frame safely prevented. A ladder can do this many times with the clamp jammed without being damaged to become. Because a relative movement takes place only between the two preferably stamped parts spring and frame instead, the due to their high accuracy of fit almost no gap. Compared to injection-molded parts, for example, individual wires of strands do not get into column of moving parts, where they would be damaged by shearing.
  • moreover the angle is closed in the unloaded state by the edge the underside of the window under bias against the insertion bevel presses and thus forms the nip. Due to the im preferably acute angle to each other standing spring angle and the insertion bevel can easily a secure terminal point are formed, on the one hand pull out and on the other hand prevents damage to the conductor.
  • The Clamping point in combination with the insertion bevel and the spring formed in the window form a clamp, the Guide the conductor safely to the nip, this precise guided by the leadership of the window sides and securely jammed, so that a conductor safely and unscathed several times in the terminal can be introduced. At least rigid ladder can by means of this clamp without actuating an actuating element simply and safely inserted and jammed in the clamp become.
  • The Clamp described here according to a second aspect The invention has a window bounded on at least three sides formed on an upper end of the spring. As already above describes a jamming, especially of individual wires a strand, thus safely prevented and a conductor can many times jammed with the clamp without being damaged to become.
  • The Window is supported on an upper portion of the frame part. The facing away from the window lower end of the spring is at a lower Supported portion of the frame part. Thus, the spring is safe and precisely prestressed in the stable frame part, and the Holder of the spring is thus not subject to inaccuracies in the spring carrying, injection-molded housing parts.
  • Of Furthermore, the edge of the underside of the window presses under pretension against the upper portion of the frame part and thus forms a nip. As a result, between the frame part and the bottom of the window on easy Way a secure terminal point are formed, on the one hand a pull out and on the other hand damage the conductor prevented.
  • Farther the window and the frame part are movable relative to each other. In this way, a flexible design of the housing is possible, because both the frame part and the spring or both parts can be made movable. It is thus not fixed, whether frame part or spring or neither form a stationary element of the terminal.
  • Further prevents a clamp according to the second aspect the invention, a jamming of individual wires of a strand and thus damaging the wires by shearing action between frame part and spring.
  • The clamp described herein according to a third aspect of the invention is formed at one end of the spring with a window bounded on at least three sides. Thus, jamming, especially of individual wires of a stranded wire, can be securely prevented and a conductor can be used many times jammed with the clamp without being damaged.
  • The End of the spring is further formed with a spring leg, which encloses a V-shaped angle with the window and forms a nip with the frame. This way will the conductor safely led to the terminal point. Especially at It is therefore possible to rigid these ladders in the terminal to jam, without an additional actuator to use.

  • The first embodiment of a terminal according to 1 shows a clamp 1 comprising a housing 2 , which preferably at its rear end with a lid 3 is closable. In a preferred embodiment, at least one pusher is located at the top of the housing 4 ,
  • The housing 2 as well as the lid 3 and the pusher 4 are preferably made of an electrically non-conductive material. Preferably, the electrically non-conductive material is a plastic. In a particularly preferred embodiment, the housing 2 , the lid 3 and the pusher 4 manufactured as injection molded parts.
  • The housing 2 also has a conductor insertion opening 6a for inserting a conductor 7 in the terminal 1 on. To the conductor insertion opening 6a closes in the case 2 trained insertion channel 6b ( 2 ) at.
  • 2 shows a lateral sectional view of the terminal 1 with a section perpendicular through the insertion channel 6a ,
  • Inside the case 2 is a frame part 8th arranged, which is electrically conductive. A feather 9 is in the frame part 8th supported. frame part 8th and spring 9 are therefore preferably in the housing 2 stored. In a preferred embodiment are frame part 8th and spring 9 each made in one piece as metal stamped and bent parts.
  • As 3 shows is the spring 9 preferably designed as a clasp-shaped leaf spring. The feather 9 is at one end with a window bounded on at least three sides 10 educated. The window 10 extends from a spring leg 9a , The spring leg 9a as well as the window 10 include a preferably obtuse angle β opened against the conductor insertion direction E. In this way one obtains an improved clearance with the conductor inserted 7 ,
  • The window 10 is at least with a window bottom 10a as well as two window pages 10b . 10b educated. When inserting a conductor 7 in the terminal 1 makes the window 10 , more precisely the preferably mutually parallel window sides 10b . 10b , a guide for the leader 7 , Preferably, the window further comprises a window top 10c on.
  • The feather 9 has at the end facing away from the window, preferably a holding element 9b on.
  • How out 4 the frame is visible 8th designed so that the spring 9 is held in this. The feather 9 is preferably with her back 9c to the insertion opening 6a of the leader 7 arranged.
  • For holding the spring 9 in the frame 8th is the window 10 at an upper area 8b of frame 8th supported. The edge of the window bottom 10a presses under pretension against the upper area 8b of the frame part 8th and thus forms a nip 11 , That from the window 10 opposite lower end of the spring provides a holding element 9b which is at a lower area 8c of the frame 8th is held. The window 10 as well as the frame 8th are movable relative to each other. The feather 9 So does not support at least one side of an injection-molded component, for example. The housing 2 , which can lead to excessive loading of the injection-molded component. Because the spring 9 exclusively in the frame 8th is held, which is preferably made as a stamped part, is a precise positioning and mounting of the spring 9 given.
  • A region of an upper region extending against the insertion direction E 8b of the frame 8th forms an insertion bevel 8a , This supports and facilitates the insertion of an electrical conductor 7 in the terminal 1 ,
  • The spring leg 9a forms in an unloaded condition of the clamp 1 ie without inserted conductor 7 , with the insertion bevel 8a of the frame 8th an open against the conductor insertion direction E, V-shaped angle α. In an unloaded condition ( 4 ) the angle α is closed. To do this press the edge of the bottom of the window 10a under bias against the insertion bevel 8a and thus forms the nip 11 , Preferably, the window is located 10 in the unloaded state on the from the nip 11 opposite side of the insertion 8a ,
  • Preferably, the V-shaped angle α is an acute angle. This will cause the insertion of the conductor 7 relieved as the leader 7 when inserting better at the insertion bevel 8a against the spring 9 can support the spring 9 bend against its bias. It is therefore possible to have a ladder 7 , in particular a rigid conductor, in the clamp 1 to jam without an external actuator to relax the nip 11 to use. A simple, safe, precise, stable and repeatable insertion and clamping of a conductor 7 in a tight spot 1 is thus given.
  • In fine-wire, particularly flexible conductors can, as explained in more detail below, and the pusher 4 to relieve the clamping point 11 when inserting the conductor 7 serve.
  • The insertion channel 6b runs in the conductor insertion direction E preferably at least up to the knee of the angle α.
  • The frame part 8th indicates at its upper area 8b an area extending in the insertion direction E 8d on. This area 8d extends from a window side 10b to the other side of the window 10b and thus serves as a guide for the window 10 during a relative movement of the window 10 with the frame 8th , Both spring 9 as well as frame 8th are preferably each made in one piece as stamped and bent parts. Stamped parts have a higher accuracy compared to injection molded parts, which is why the areas between windows 10 and frame 8th are almost gap-free. There the window 10 in the spring 9 is configured, so it can with a relative movement to the frame 8th For example, do not come to jamming of individual wires of a strand.
  • 5 shows a loaded condition of the terminal 1 , ie with inserted conductor 7 , The leader 7 has an isolated area 7a as well as a stripped area 7b on. Latter area 7b represents a conductor end, which is in the terminal 1 is introduced. In this loaded state forms at least a part of the window 10 a passage 10d in the area of the knee of the angle α. Preferably, the window top serves 10c in the loaded state as a stop to limit a maximum deflection or bending of the spring 10 , At maximum bending of the spring 10 comes the window top 10c in contact with the area 8d and prevents further deflection of the spring 10 ,
  • The nip 11 is designed such that it serves as a trigger guard for the conductor 7 in a loaded condition.
  • How out 1 Obviously, the pushers are 4 pivotable in the housing 2 stored. The pusher 40 shows a pusher 4 in latching position, for example, during use of the terminal 1 when the pusher is not needed. By means of locking elements 5 becomes the pusher 4 held in the locked position. This is the pusher 4 so far swung back, until he behind the locking elements 5 locks. The pusher 41 shows a pusher 4 in operating position.
  • According to 2 points the pusher 4 a push piece 4a and a trigger lever 4b on. The pusher 4 is pivotable by means of a joint 4d in the case 2 stored. Furthermore, the pusher points 4 on one side of the trigger lever 4b a pressing surface 4c on, which in the operating position of the pusher 4 at an upper end of the window 10 is applied. By means of the pusher 4 Thus, a relative movement between the spring 9 or the window 10 and the frame 8th be executed. This serves the pusher 4 as an external actuator to relieve the terminal point 11 , That way the leader can 7 without damage from the terminal 1 be pulled out. When inserting particularly flexible conductors, the pusher 4 also to relieve the terminal point 11 serve.
  • Preferably, the frame part forms 8th a stationary element and the spring a movable element. Of course, the clamp 1 also be designed so that the spring 9 a stationary element and the frame part 8th forms a movable element. It is also possible that both frame part 8th as well as spring 9 form moving elements.
  • The 6 and 7 show a modification of the terminal according to the first embodiment; more precisely another embodiment of a frame 108 , The basic principle of this modification corresponds to that of the terminal according to the first embodiment.
  • The frame 108 also has an insertion bevel according to the invention 108a such as the insertion bevel described above 8a , on. Furthermore, the frame points 108 an arcuate, web-like middle area 108e for connecting an upper area 108b and a lower area 108c on. The areas 108e are the same shape as the knee area 9d the feather 9 , At maximum deflection of the spring 9 is the knee area 9d the feather 9 congruent with the middle area 108e of the frame 108 , The area 108e of the frame 108 thus serves as a stop at deflection of the spring 9 ,
  • In a particularly preferred embodiment, the frame part 8th furthermore with at least one solder pin 112 for connecting the terminal with a hole of a printed circuit board (not shown). The solder pin 112 preferably extends from the lower region 108c of the frame 108 downward.
  • 8th and 9 show a further modification of the terminal according to the first embodiment; more precisely another embodiment of the frame part 208 and the spring 209 , The basic principle of this modification corresponds to that of the terminal according to the first embodiment.
  • In a lower area 208u is the frame 208 designed in a U-shaped profile. A down from the bottom 208u extending upper area 208o has the same profile as the spring in this area 209 , In the unloaded state is the upper area 208o of the frame 208 over its entire length in contact with the corresponding area of the spring 209 ,
  • The upper end 208e of the frame 208 is opposite to the conductor insertion direction E preferably angled at right angles. Below the angled end 208e is located in the upper area 208o of the frame 208 a window 208f through which the conductor 7 can be introduced. Along the bottom of the end 208e runs a guide element 208g and extends in the conductor insertion direction E. The guide element 208g thus serves on the one hand as an insertion bevel 208a such as the insertion bevel described above 8a , On the other hand, the guide element serves 208g for guiding the spring 209 like the range described above 8d ,
  • The feather 209 is at one end with a window bounded on at least three sides 210 educated. The window 210 is at least with a window bottom 210a as well as two window pages 210b . 210b educated. The window 210 extends from a spring leg 209a , The edge of the window bottom 210a presses against the guide element under pretension 208g , more precisely, the insertion bevel 208a and thus forms a nip.
  • The following describes the jamming and loosening of electrical conductors in a clamp according to the invention. The cited example, of course, extends over all embodiments of the aforementioned embodiment, especially over in the 1 to 9 shown embodiments.
  • A leader 7b a leader 7 is through the conductor insertion opening 6a in the insertion channel 6b of the housing 2 the clamp 1 introduced. The insertion channel 6b leads the leader 7b up to the knee of the angle α, enclosed by the insertion bevel 8a of the frame 8th and the thigh 9a the feather 9 ,
  • By the on the ladder 7 in the conductor insertion direction E exerted pressure is the conductor 7 along the insertion slope 8a pressed and thus safe against the spring 9 supported. The leader 7 bends due to the insertion angle at an acute angle α to each other 8a and spring legs 9a the feather 9 relative to the frame 8th downward. This will make the window 10 the feather 9 at least partially on the side of the nip 11 , related to the area 8d , emotional. This creates a passage 10d in the area of the knee of the angle α, through which the conductor end 7b continues to be introduced. In loaded condition is the conductor 7 between frames 8th and spring 9 finally jammed. The nip 11 , more precisely, the bottom of the window 10a , make for the leader 7 a trigger guard, so the leader 7 not from the clamp 1 can slip.
  • To release the connection is the respective pusher 4 released from its rest position and pivoted in operating position. By pressure on the pressing part 4a is over the pressing surface 4c a pressure on the spring 9 or the window 10 exercised. This pressure acts on the bias of the spring 9 and thus the nip becomes 11 relaxed. The leader 7b As a result, it can easily turn off the clamp 1 to be pulled. Subsequently, the pusher 4 brought back to its rest position.
  • The pusher 4 can also be used for flexible conductors when inserting the conductor to relax the nip 11 be used when the rigidity of the conductor is insufficient to the spring 9 against their bias to bend and the passage 10d for the leader 7 release.
  • The jamming and loosening of electrical conductors in a terminal according to the modifications of 6 to 9 is identical to the steps described above.
  • The second embodiment of a clamp according to the 10 and 11 has essentially the same components as the clamp 1 according to the first embodiment. The components described in the first embodiment and therefore known components will not be explained again at this point.
  • The second embodiment of a terminal according to 10 and 11 shows, compared to the embodiments described above, especially an altered design of the frame 308 as well as the spring 309 ,
  • The clamp has a frame part 309 on, which is electrically conductive, and a spring 308 in the frame part 309 is held. Further, the spring 309 at one end 309e with a window bounded on at least three sides 310 educated. The end 309e the feather 309 is further with a spring leg 309a formed, which forms a free end of the spring. The spring leg 309a closes with the window 310 a V-shaped, preferably acute angle γ. The spring leg 309a forms with the frame 308 a nip (not shown).
  • Preferably, the spring leg forms 309a in the unloaded condition of the clamp with an insertion bevel 308a of the frame part 308 an open against the conductor insertion direction E, V-shaped angle δ. In a particularly preferred embodiment, the angle δ is an acute angle.
  • Preferably, the angle δ is closed in the conductor insertion direction E in the unloaded state by the end edge of the spring leg 309a under bias against the insertion bevel 308a suppressed.
  • Preferably, the window 310 and the frame part 308 movable relative to each other.
  • From the above explanations is thus a simple, safe, precise, stable and multiple feasible insertion and jamming of a conductor 7 in a tight spot 1 given.
  • Preferably, the window is located 310 in the unloaded state at least partially on the same side of the insertion bevels 308a like the nip. In a particularly preferred embodiment, the window sides are preferably mutually parallel 310b . 310b of the window 310 arranged in the conductor insertion direction E in front of the nip. In this way, a particularly safe and precise introduction of the conductor 7 , as this is brought into position just before the nip and safely guided to the terminal point.
  • The area of the frame 308 where the insertion bevel 308a is located, extends over the entire width of the window 310 from a window side 310b to the other side of the window 310b , The window 310 is kept safe in this way. Preferably, the frame is 308 and the spring 309 To one-piece stamped and bent parts, and therefore jamming, for example. Of individual wires of a strand, due to the high accuracy of fit is not possible. A conductor can thus be repeatedly clamped without damage in the terminal and released again.
  • The frame 308 and the spring 309 are preferably in a housing, especially a housing 2 as described above, held. This housing preferably has pushers described above 4 for relieving the nip on.
  • The procedure for clamping and releasing electrical conductors in a clamp according to the second embodiment is identical to that of the first embodiment. The only difference is that the electrical conductor 7 when inserting into the clamp before the clamping point by means of the window sides 310b . 310b of the window 310 brought into position and thus safely guided to the terminal point.
  • The Nip can, in all embodiments, not only by indirect pressure by means of a pusher or be relieved of another actuator.
  • Also by direct pressure on the window top, which is relative to the nip lies beyond the chamfers, the nip can be relieved.
