Abstract

The clamp has a frame part (8), which is electrically conductive, and a spring (9), which is supported in the frame part. The bracket (9a) of the spring forms a V-shaped angle in an unloaded condition of the clamp without interposed conductors, with an insertion bevel (8a) of the frame part against opened conductor introduction direction (E). The end of the spring is formed with three sides delimited window (10), which extends from the spring bracket. The angle is closed in the unloaded condition as the edge of the window lower side presses under pre-loading against the insertion bevel.

Description

The invention relates to a terminal for connecting electrical conductors, comprising an electrically conductive frame part, hereinafter also called frame, and a spring held in the frame. Usually, these electrically conductive parts are surrounded by an insulating housing.

Numerous terminals already exist for connecting and disconnecting electrical conductors. These terminals are used firstly to make electrical contact with a conductor. On the other hand, the conductor is held mechanically by means of the clamp. This ensures a sufficient peel strength. In this way, an electrical connection between a conductor and an electronic component, such as, for example, an operating element of luminous bodies, is ensured.

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 extends the contact part 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.

Thus, to insert flexible and rigid conductors, the actuation of the pusher cap is necessary to release the insertion opening. The biasing force of the spring produced as a stamped part so loads when pressing the trigger cap on this. This leads to a high load on the housing parts, as it is the handle cap, as well as the other housing parts, injection molded parts. Furthermore, only the injection-molded housing via insertion opening provides a guide for the conductor, which is why due to production-related deviations in the injection molding process, the terminal provides poor guidance to 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 end of the spring in Leitereinführrichtung by the Hubschlitz extends through 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 facilitate the insertion of electrical conductors and to prevent jamming of individual wires of a strand between the window and frame or spring.

This object is protected by the features of the independent claims. The dependent claims further form the central idea of the invention in a particularly advantageous manner.

According to a first aspect of the invention, the terminal for connecting electrical conductors has 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 state of the terminal, ie without inserted conductor, with an insertion bevel of the frame part forms a Leiteinführrichtung open, V-shaped angle. One end of the spring is formed with a window bounded on at least three sides. The window extends from the spring leg. The angle is closed in the unloaded state by the edge of the window underside presses under bias against the insertion bevel and thus forms the nip.

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. One end of the spring is formed with a window bounded on at least three sides. The end of the spring is further formed with a spring leg, which includes with the window a V-shaped angle and forms a nip with the frame.

The clamp described here according to a first aspect of the invention has a V-shaped angle open to the conductor insertion direction, formed from a leg of the spring and an insertion bevel of the frame part. In this way, the insertion of an electrical conductor is simplified because the conductor is guided during insertion through the spring leg and the insertion of the frame to the nip. Furthermore, it is made possible by the insertion that the head against the spring safely supported and thus the spring can easily bend. Especially, but not exclusively with rigid conductors, it is therefore possible to jam this in the terminal, without additionally operating an actuator.

Furthermore, one end of the spring is formed with a window bounded on at least three sides, which extends from the spring leg. Since the window is formed in the spring, jamming, especially of individual wires of a strand between the window or spring and frame is reliably prevented. A ladder can be many Male clamped with the clamp without being damaged. For a relative movement takes place only between the two preferably stamped parts spring and frame, which have almost no gap due to their high accuracy of fit. Compared to injection-molded parts, for example, individual wires of strands can not fall into gaps in the moving parts, where they would be damaged by shearing action.

In addition, the angle in the unloaded state is closed by the edge of the underside of the window presses under pretension against the insertion bevel and thus forms the nip. Due to the preferably acute angle to each other standing spring angle and the insertion can be easily formed a secure terminal point, on the one hand pull out and on the other hand prevents damage to the conductor.

The nip in combination with the insertion bevel and the spring-formed window form a clamp that guides the conductor safely to the nip, guides it precisely through the guide of the window sides and securely clamped so that a conductor safely and unscathed several times inserted into the terminal can be. At least rigid conductors can be simply and safely inserted and clamped into the clamp by means of this clamp without actuating an actuating element.

The clamp described herein according to a second 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 strand, can be safely prevented, and a conductor can be many Male clamped with the clamp without being damaged.

The end of the spring is further formed with a spring leg, which includes with the window a V-shaped angle and forms a nip with the frame. In this way, the conductor is safely guided to the terminal point. Especially with rigid conductors, it is therefore possible to jam this in the terminal, without additionally operating an actuator.

The first embodiment of a terminal according to FIG. 1 shows a clamp 1 comprising a housing 2. The housing preferably has at its rear end an opening 2a (see. FIG. 2 ), through which the terminal 1 can be inserted into the housing 2. The opening 2 a of the housing 2 is also preferably closable with a cover 3. In a preferred embodiment, at least one pusher 4 is located at the top of the housing.

The housing 2 and the cover 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 cover 3 and the pusher 4 are manufactured as injection-molded parts.

The housing 2 further has a conductor insertion opening 6a for inserting a conductor 7 into the clamp 1. At the conductor insertion opening 6a, a trained in the housing 2 insertion channel 6b closes ( Fig. 2 ) at.

FIG. 2 shows a lateral sectional view of the terminal 1 with a section perpendicular through the insertion channel 6a.

Within the housing 2, a frame part 8 is arranged, which is electrically conductive. A spring 9 is held in the frame part 8. Frame part 8 and spring 9 are thus preferably mounted in the housing 2. In a preferred embodiment, frame part 8 and spring 9 are each made in one piece as metal stamped and bent parts.

The cover 3 preferably has at its edge regions at least one latching elements 3a, which corresponds to the housing 2 provided with the lid 2 in the housing 2 locking elements 2b with the lid. Thus, the lid 3 is securely held and the housing 2 is securely closed.

The cover 3 may further comprise at least one positioning element 3b, which preferably extends from the cover 3 to the housing inside out, such that it presses against the clamp 1, preferably the frame part 8, so serves as a stop to the clamp 1 safely in to position the housing 2. In this way, a fast, safe and easy-configured and manufactured positioning of the terminal 1 in the housing 2 is provided, which is also easy to solve again.

As FIG. 3 shows, the spring 9 is preferably designed as a clasp-shaped leaf spring. The spring 9 is formed at one end with a window 10 bounded on at least three sides. The window 10 extends from a spring leg 9a. The spring leg 9a and the window 10 include an open against the conductor insertion E, preferably obtuse angle β. In this way, one obtains an improved clearance width with inserted conductor. 7

The window 10 is formed at least with a window bottom 10a and two window sides 10b, 10b. When inserting a conductor 7 into the terminal 1, the window 10, more precisely the preferably mutually parallel window sides 10b, 10b, a guide for the conductor 7. Preferably, the window further comprises a window top 10c on.

The spring 9 preferably has a holding element 9b at the end facing away from the window.

How out FIG. 4 it can be seen the frame 8 is designed such that the spring 9 is held in this. The spring 9 is preferably arranged with its back 9c to the insertion opening 6a of the conductor 7 back.

For holding the spring 9 in the frame 8, the window 10 is supported on an upper portion 8b of the frame 8. The edge of the underside of the window 10a presses against the upper area 8b of the frame part 8 under pretension and thus forms a clamping point 11. The lower end of the spring facing away from the window 10 constitutes a holding element 9b, which is held on a lower area 8c of the frame 8 , The window 10 and the frame 8 are movable relative to each other. The spring 9 is thus not supported on at least one side on an injection-molded component, for example the housing 2, which can lead to excessive loading of the injection-molded component. Since the spring 9 is held exclusively in the frame 8, which is preferably made as a stamped part, the holder of the spring 9 is thus not subject to inaccuracies in spring-bearing, injection-molded housing parts. As a result, a precise positioning and mounting of the spring 9 is given and the spring 9 is securely and accurately biased in the stable frame part 8. Since both the frame 8 and the spring 9 or both parts can be designed to be movable, thus a flexible embodiment of the housing 2 is possible. It is therefore not specified whether frame 8 or spring 9 or neither form a stationary element of the terminal 1.

A region of an upper region 8b of the frame 8 extending against the insertion direction E 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 state of the terminal 1, ie without inserted conductor 7, with the insertion bevel 8a of the frame 8 a against the conductor insertion E open, V-shaped angle α. In an unloaded condition ( Fig. 4 ) the angle α is closed. For this purpose, the edge of the underside of the window 10a presses under bias against the insertion bevel 8a and thus forms the nip 11. Preferably, the window 10 is in the unloaded state on the side facing away from the nip 11 side of the insertion 8a.

Preferably, the V-shaped angle α is an acute angle. As a result, the insertion of the conductor 7 is facilitated because the conductor 7 can be better supported during insertion on the insertion bevel 8a against the spring 9 to bend the spring 9 against its bias. It is therefore possible to clamp a conductor 7, in particular a rigid conductor, in the terminal 1, without using an external actuating element for relaxing the clamping point 11. A simple, safe, precise, stable and multiple feasible insertion and jamming of a conductor 7 in the terminal 1 is thus given.

In fine-wire, particularly flexible conductors can, as explained in more detail below, the pusher 4 serve to relieve the nip 11 during insertion of the conductor 7.

The insertion channel 6b preferably extends in the conductor insertion direction E at least as far as the knee of the angle α.

The frame part 8 has an area 8d extending in the insertion direction E at its upper area 8b. This region 8d extends from one side of the window 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 8. Both spring 9 and frame 8 are preferably made in one piece as stamped and bent parts. Stampings have a higher accuracy compared to injection molded parts, which is why the areas between window 10 and frame 8 are almost gap-free. Since the window 10 is configured in the spring 9, so it can not come to jamming of individual wires of a strand in a relative movement to the frame 8, whereby also damaging the wires, for example. Due to shear effects between the frame 8 and spring 9, safely avoided.

FIG. 5 shows a loaded state of the terminal 1, ie with inserted conductor 7. The conductor 7 has an insulated area 7a and a stripped area 7b. The latter area 7b represents a conductor end which is inserted into terminal 1. In this loaded state at least a part of the window 10 forms a passage 10d in the region of the knee of the angle α.

Preferably, the window top 10c in the loaded state serves as a stop for limiting a maximum deflection or bending of the spring 10. At maximum deflection of the spring 10, the window top 10c comes into contact with the area 8d and prevents further deflection of the spring 10th

The nip 11 is designed such that it serves as a trigger guard for the conductor 7 in a loaded state.

How out FIG. 1 can be seen, the pushers 4 are pivotally mounted in the housing 2. The pusher 40 shows a pusher 4 in the locked position, for example. During the use of the terminal 1 when the pusher is not needed. By means of locking elements 5, the pusher 4 is held in the latching position. For this purpose, the pusher 4 is pivoted back until it snaps behind the locking elements 5. The pusher 41 shows a pusher 4 in the operating position.

According to FIG. 2 the pusher 4 has a pusher part 4a and a pusher lever 4b. The pusher 4 is pivotally mounted in the housing 2 by means of a hinge 4d. Furthermore, the pusher 4 on one side of the pusher lever 4b on a pressing surface 4c, which rests in the operating position of the pusher 4 at an upper end of the window 10. By means of the pusher 4 can thus be carried out a relative movement between the spring 9 and the window 10 and the frame 8. As a result, the pusher 4 serves as an external actuating element for relieving the nip 11. In this way, the conductor 7 can be pulled out of the terminal 1 without damage. When introducing particularly flexible conductors, the pusher 4 can also serve to relieve the nip 11.

Preferably, the frame part 8 forms a stationary element and the spring is a movable element. Of course, the clamp 1 can also be designed so that the spring 9 forms a stationary element and the frame part 8 a movable element. It is also possible that both frame part 8 and spring 9 form movable elements.

The FIGS. 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 clamp according to the first embodiment.

The frame 108 also has an insertion bevel 108a according to the invention, like the insertion bevel 8a described above. Furthermore, the frame 108 has an arcuate, web-like central portion 108e for connecting an upper portion 108b and a lower portion 108c. The areas 108e are identical in shape to the knee area 9d of the spring 9. At maximum deflection of the spring 9, the knee area 9d of the spring 9 is congruent with the middle area 108e of the frame 108. The area 108e of the frame 108 thus serves as a stop when the spring is deflected 9th

In a particularly preferred embodiment, the frame member 8 is further provided with at least one solder pin 112 for connecting the terminal to a hole of a circuit board (not shown). The solder pin 112 preferably extends downwardly from the lower portion 108c of the frame 108.

FIGS. 8 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, the frame 208 is configured in a U-shaped profile. An upper portion 208o extending from the lower portion 208u has the same profile as the spring 209 in this region. In the unloaded state, the upper portion 208o of the frame 208 is in contact with the corresponding portion of the spring 209 over its entire length.

The upper end 208e of the frame 208 is preferably angled against the conductor insertion direction E at right angles. Below the angled end 208e is located in the upper portion 208o of the frame 208, a window 208f, through which the conductor 7 can be inserted. Along the underside of the end 208e, a guide element 208g extends and extends in the conductor insertion direction E. The guide element 208g thus serves on the one hand as an insertion bevel 208a, like the insertion bevel 8a described above. On the other hand, the guide member 208g serves to guide the spring 209 like the above-described portion 8d.

The spring 209 is formed at one end with a window 210 bounded on at least three sides. The window 210 is formed at least with a window bottom 210a and two window sides 210b, 210b. The window 210 extends from a spring leg 209a. The edge of the window bottom 210a presses under tension against the guide member 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 FIGS. 1 to 9 shown embodiments.

A conductor end 7 b of a conductor 7 is inserted through the conductor insertion opening 6 a in the insertion channel 6 b of the housing 2 of the terminal 1. The insertion channel 6b guides the conductor end 7b to the knee of the angle α, enclosed by the insertion bevel 8a of the frame 8 and the leg 9a of the spring 9.

As a result of the pressure exerted on the conductor 7 in the conductor insertion direction E, the conductor 7 is pressed along the insertion bevel 8a and thus securely supported relative to the spring 9. The conductor 7 bends the spring 9 relative to the frame 8 down due to the acute angle α to each other standing chamfer 8a and spring legs 9a. Thereby, the window 10 of the spring 9 is at least partially moved to the side of the nip 11 with respect to the area 8d. This forms a passage 10d in the region of the knee of the angle α, through which the conductor end 7b is further introduced. In the loaded state, the conductor 7 between frame 8 and spring 9 is finally jammed. The clamping point 11, more precisely the lower window side 10 a, forms a trigger safety device for the conductor 7, so that the conductor 7 can not slip out of the clamp 1.

To release the connection, the respective pusher 4 is released from its detent position and pivoted into the operating position. By pressure on the pressing member 4 a pressure is exerted on the spring 9 or the window 10 via the pressing surface 4 c. This pressure counteracts the bias of the spring 9 and thus the nip 11 is relaxed. As a result, the conductor end 7b can be easily pulled out of the terminal 1. Subsequently, the pusher 4 is returned to its rest position.

The pusher 4 can be used in flexible conductors even when inserting the conductor to relax the nip 11, if the rigidity of the conductor is not sufficient to bend the spring 9 against its bias and release the passage 10d for the conductor 7.

The jamming and loosening of electrical conductors in a terminal according to the modifications of FIGS. 6 to 9 is identical to the steps described above.

The second embodiment of a clamp according to the Figures 10 and 11 has substantially the same components as the terminal 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 Figures 10 and 11 shows, compared to the embodiments described above, especially a modified design of the frame 308 and the spring 309th

The clamp has a frame part 309, which is electrically conductive, and a spring 308, which in the frame part 309 is held. Further, the spring 309 is formed at one end 309e with a window 310 bounded on at least three sides. The end 309e of the spring 309 is further formed with a spring leg 309a forming a free end of the spring. The spring leg 309a includes with the window 310 a V-shaped, preferably acute angle γ. Spring leg 309a forms a nip with frame 308 (not shown).

Preferably, the spring leg 309a forms in the unloaded state of the terminal with an insertion bevels 308a of the frame part 308 a against the conductor insertion direction E open, 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 309 a biased against the insertion bevel 308 a.

Preferably, the window 310 and frame member 308 are movable relative to each other.

From the above explanations is thus given a simple, safe, precise, stable and multiple feasible insertion and jamming of a conductor 7 in the terminal 1.

Preferably, the window 310 is in the unloaded state at least partially on the same side of the insertion bevels 308a as the nip. In a particularly preferred embodiment, the preferably mutually parallel window sides 310b, 310b of 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, since this is already brought into position just before the nip and safely guided to the nip.

The area of the frame 308 at which the insertion bevel 308a is located extends over the entire width of the window 310 from one window side 310b to the other window side 310b. The window 310 is securely guided in this way. The frame 308 and the spring 309 are preferably one-piece stamped and bent parts, and therefore jamming, for example of individual wires of a strand, is not possible due to the high accuracy of fit. A conductor can thus be repeatedly clamped without damage in the terminal and released again.

The frame 308 and the spring 309 are preferably supported in a housing, especially a housing 2 as described above. This housing preferably has pushers 4 described above for relieving the nip.

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 inserted into the terminal before the nip by means of the window sides 310b, 310b of the window 310 is brought into position and thus safely guided to the nip.

The nip can, in all embodiments, not only be relieved by indirect pressure by means of a pusher or other actuator.

Even by direct pressure on the window top, which is with respect to the nip beyond the chamfers, the nip can be relieved.

In the following, a further preferred embodiment of a lid 400 and housing 420 according to the invention is described, in addition to the shown frame 1008 with spring 1009 also any frame according to the invention with springs, in particular all the aforementioned frame 8, 108, 208, 308 with springs 9, 209, 309 can be used.

In the Figures 12 . 13a and 13b an embodiment of a lid 400 according to the invention is shown. In this case, the cover 400 preferably has a conductor insertion channel 401 with a conductor insertion opening 402, which are formed in the same way as the conductor insertion channel 6b and the conductor insertion opening 6a. These are preferably formed integrally with the lid 400.

The lid 400 further includes a pusher 404 preferably integrally formed therewith. The pusher 404 is advantageously arranged above the insertion channel 401 and pivotally connected at its connection point 405 with the lid 400 and thus pivotally mounted on this. In this way, on the one hand saves additional parts and thus also reduces manufacturing and assembly costs.

The lid 400 further includes a guide member 406 for the pusher 404. The guide member 406 is also preferably integrally formed with the lid 400. A first connecting element 407 of this guide part 406 preferably extends from the conductor insertion opening 402 in the same direction away from the cover 400, in which also the pusher 404 extends, so preferably upwards. The first connecting element 407 is advantageously at least partially so flexible that the guide part 406 can be pivoted relative to the cover 400, more precisely to the conductor insertion channel 401.

The guide part 406 preferably has two guide elements 406a, which in turn extend away from the first connection element 407. A second connecting element 408 is arranged, with reference to the guide elements 406a, on the end of the guide part 406 opposite the first connecting element 407, where it connects the guide elements 406a such that an elongated guide opening is preferably formed by the two guide elements 406a and the two connecting elements 407, 408 409 is formed. The two guide elements 406a are preferably arranged substantially parallel to one another, wherein the distance of the two guide elements 406a preferably corresponds at least to the width of the pusher 404, so that the guide member 406 can be pivoted with its guide opening 409 via the pusher 404 and this as a lateral guide can serve. This will be described in more detail below.

FIG. 13a shows the lid 403, as it is arranged in the installed state, that is, in particular, how the guide member 406 is pivoted about the pusher 404, and FIG. 14 shows a clamp 1000, having the lid installed in a housing 420 with inventive frame 1008 and spring 1009. It is also any other inventive frame 8, 108, 208, 308 with spring 9, 209, 309 inserted into the housing 420.

It is in the FIGS. 13a and 14 to recognize that in an installed state, the guide member 406 is pivoted with its guide opening 409 via the pusher 404, so that the pusher 404 protrudes from the guide opening 409 upwards. In this way, the pusher 404 is freely accessible from the outside and can be easily operated, for example, to relieve a terminal point 1011. Characterized in that the distance between the two guide elements 406a at least equal to the width of the pusher 404, the guide elements 406a serve as a lateral guide for the pusher 404 during a pivoting movement and thus prevent lateral bending away or jamming of the pusher 404 during the pivoting movement to relieve the Clamping point 1011. With regard to further advantages and features of the pusher 404, reference is made to the above statements with respect to the pusher 4.

The second connecting element 408 preferably has guide grooves 410 in order to securely connect the guide part 406 of the cover 400 to the housing 420, which will be described in more detail below. For this purpose, the second connecting element 408 preferably further comprises a holding web 411 in order to achieve a secure clamping of the guide part 406 to the housing 420 and to prevent slippage of the guide part 406 from the housing 420 in an installed state. This will be explained in more detail below, in particular in the comments on the housing 420.

The cover 400 further preferably has a retaining element 412 extending from the cover 400 below the insertion opening 402. This preferably has a substantially triangular shape, wherein the width of the holding element 412 transversely to the conductor insertion direction E with increasing distance from the lid 400 is wider down. On the underside of the holding element 412, that is to say on the side opposite the lid 400, the holding element 412 preferably has a hooking element 413 extending downwardly therefrom. The holding element 412 and the Verhakelement 413 are used for safe installation and secure fixing of the lid 400 in the housing 420. This will be discussed in more detail later in the description.

The conductor insertion channel 401, the pusher 404, the guide member 406 and the holding member 412 are preferably integrally formed with each other and form the lid 400.

The housing 420 preferably has a substantially L-shaped cross-section. A first leg of the L-shaped housing 420, also referred to below as bottom 422, extends in the conductor insertion direction E and serves as the bottom part of the housing 420. A second leg of the housing 420, also referred to as rear side 423, preferably extends orthogonally from the bottom 422 and is arranged in the conductor insertion direction E at the rear end of the bottom 422. Furthermore, the housing 420 preferably has lateral boundary walls 421 which delimit at least the terminal space to the sides to the outside. The boundary walls 421 and the bottom 422 and the back 423 of the housing 420 are preferably formed integrally with each other and thus preferably form an upwardly and forwardly open housing 420.

The underside 422 has, at its rear end 423 opposite end, hereinafter referred to as insertion 424, one looking in the conductor insertion direction E, triangular groove 425 (see also FIG. 18 ) that with the Holding element 412 of the lid 400 corresponds. In this way, the lid 400 can be easily pushed onto the housing 420. Due to the triangular shape, an undercut is further formed in the assembled state, so that cover 400 and housing 420 are positively connected and thus securely connected.

In order to avoid unwanted pushing out and to ensure a secure cohesion of the parts, the housing 420 in the triangular groove 425 preferably has a downwardly extending recess 426 which corresponds to the Verhakelement 413 of the lid 400. If the lid 400 is pushed with its holding element 412 onto the groove 425 of the housing 420, the Verhakelement 413 engages in the end position or installation position in the recess 426 such that the lid 400 is securely held in the housing 420. The groove 425 is advantageously formed so that it has a rear stop 425 a, against which the lid 400 abuts, as soon as it is inserted to the installation position, so that the lid 400 is securely clamped between stop 425 a and recess 426.

The recess 426 is preferably designed such that it completely penetrates the underside 422 of the housing 420, so that the Verhakelement 413 of the lid 400 in the installed state is freely accessible from below. In this way, the Verhakelement 413, for example by means of a tool such as a screwdriver, are released by pressing out of the recess 425 and the lid 400 can be easily pulled out of the housing 420. As a result, a simple and secure connection between the cover 400 and the housing 420 is provided which, moreover, can be easily released again.

The rear side 423 of the housing 420 preferably has guide rails 428, which correspond to the guide grooves 410 of the second connecting element 408 of the guide part 406, at its end facing away from the underside 422, referred to below as the holding side 427. Further, the rear side 423 on its holding side 427 has a projection 429 which extends to the inside of the housing so that it can correspond to the holding web 411 of the guide member 406. Thus, after the lid 400 has been pushed with its holding element 412 on the groove 425 of the housing 420, the guide member 406 pivoted about the pusher 404 and also be locked to the housing 420. Thus, the housing 420 is securely connected to the lid 400 in two places and closed and at the same time a pusher 404 mounted with a guide, the lid 400 can be easily removed again from the housing 420.

It is also possible for the housing 420 to have openings 430 on its underside 422, that is to say the first leg, through which the soldering tongs 112, 1012 of frames 8, 108, 208, 308, 1008 according to the invention can be pushed through, if they are in the housing 420 are used.

The housing 420 and the cover 400 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 420 and the lid 400 are manufactured as injection molded parts.

• Rahmen 8, 108, 208, 308, 1008 und Feder 9, 209, 309, 1009 werden im zusammengesetzten Zustand zunächst von oben auf die Unterseite 422 des Gehäuses 420 gesetzt. Weist der Rahmen 9, 209, 309, 1009 Lötpinne 112, 1012 auf, werden diese durch die genannten Öffnung 430 in der Unterseite 422 des Gehäuses 420 gesteckt, so dass sie von außen frei zugänglich sind und die Klemme 1000 in fertig zusammengesetztem Zustand einfach kontaktiert bzw. auf entsprechende Kontaktstellen aufgesteckt, verlötet oder in anderer bekannter Weise verbunden werden kann. Dann wird der Deckel 400 mit seinem Halteelement 412 in Leitereinführrichtung E in die Nut 425 des Gehäuses 420 eingeschoben, bis der Deckel 400 an den Anschlag 425a stößt und das Verhakelement 413 in die Vertiefung 426 einrastet. Der Deckel 400 ist auf diese Weise bereits sicher mit dem Gehäuse 420 verbunden. Im nächsten Schritt wird das Führungsteil 406 über den Drücker 404 geschwenkt und mit den im Führungsteil 406 eingeformten Nuten 410 auf die Führungsschienen 428 des Gehäuses 420 gesteckt, bis der Vorsprung 429 den Haltesteg 411 hintergreift und damit das Führungsteil 406 einrastet. Deckel 400 und Gehäuse 420 sind somit an zwei Stellen sicher miteinander verbunden. In diesem geschlossenen Zustand sind die vordere und obere Öffnung des Gehäuses 420 vorzugsweise ebenfalls verschlossen, der Rahmen 1008 mit der Feder 1009 sicher in dem Gehäuse 420 angeordnet und der Drücker 404 wie auch die ganze Klemme 1000 einsatzbereit.

The assembly of a clamp 1000 according to the invention, comprising housing 420 with lid 400 and frame 8, 108, 208, 308, 1008 with spring 9, 209, 309, 1009, proceeds as follows:

• Frame 8, 108, 208, 308, 1008 and spring 9, 209, 309, 1009 are placed in the assembled state, first from the top to the bottom 422 of the housing 420. If the frame 9, 209, 309, 1009 has soldering spindles 112, 1012, these are inserted through said opening 430 in the underside 422 of the housing 420 so that they are freely accessible from the outside and simply contact the clamp 1000 in the finished assembled state or attached to corresponding contact points, soldered or can be connected in any other known manner. Then, the lid 400 is inserted with its holding element 412 in the conductor insertion direction E in the groove 425 of the housing 420 until the lid 400 abuts the stop 425 a and the Verhakelement 413 engages in the recess 426. The lid 400 is already securely connected to the housing 420 in this way. In the next step, the guide member 406 is pivoted about the pusher 404 and inserted with the formed in the guide member 406 grooves 410 on the guide rails 428 of the housing 420 until the projection 429 engages behind the holding web 411 and thus the guide member 406 engages. Cover 400 and housing 420 are thus securely connected to each other in two places. In this closed state, the front and top openings of the housing 420 are preferably also closed, the frame 1008 with the spring 1009 securely located in the housing 420 and the pusher 404 as well as the entire clamp 1000 ready for use.

Preferably, the second connecting element 408 is formed so that it has a lower stop 414, which in the closed state of the guide member 406 with a Part of the frame member 1008 comes into contact, so that on the one hand, the guide member 406 is securely and firmly positioned between the projection 429 and the stopper 414 and on the other hand, the frame part 1008 with spring 1009 securely fixed on the lower stop 414 in the housing 420.

In order to relieve the clamping point 1011 of the inventive terminal 1000, is, as in FIG. 13b shown, the pusher 404 along the opening 409 of the guide member 406 pivoted. A pressure surface on the spring 1009 is then exerted from above via a pressing surface 404a of the pusher 404, so that the clamping point 1011 is relieved and a conductor can be inserted or pulled out of the clamp 1000, more precisely the clamping point 1011.

The second connecting part 408 can be designed such that it forms a front stop 415 for this pressed button 404, so that a certain maximum presser travel can be predefined, for example, not to overstretch the spring 1009.

It should also be noted that the spring 1009 preferably at its end facing the pusher 404 above the window 1010 preferably has a curved, preferably part-circular outlet 1020, whose rounded, curved surface is in contact with the pusher 404 and on the pusher 404 on the spring acts. Upon actuation of the pusher 404, the spout 1020 slides smoothly over the pusher surface 404a due to its curved shape. Thus, a jamming or entanglement of the spring 1009 is avoided with the pusher 404 and a gentle deflection of the spring 1009 by means of the pusher 404 is ensured. Also, a manual deflection of the spring 1009 is thus more comfortable because not on a small, sharp upper edge of the window, but can be pressed on a larger area of the window top. Of course, the feature of the spout 1020 may be formed in all the springs 9, 209, 309, 1009 according to the invention for the purpose stated above.

In addition, it should also be noted that the cover 400 may be formed without pusher 404, for example, to avoid a misoperation. In this case, the terminal 1011 would be relieved by pressure on the spring or window top, for example by means of a special tool or screwdriver.

In FIG. 15 A further embodiment of a clamp 2000 according to the invention is shown, comprising a housing 520 with cover 500 and a frame 1008 according to the invention with spring 1009. The housing 520 and the cover 500 have essentially the same features as the housing 420 and the cover 400. In this, as already mentioned above, any form of inventive frame with springs, in particular all the aforementioned frame 8, 108, 208, 308, 1008 with springs 9, 209, 309, 1009 can be used. In the following, therefore, only the differences are discussed and, moreover, reference is made to the above statements.

The housing 520 differs from the housing 420 in that it has an opening 540, preferably in the back 523 at the level of the nip 1011, which serves as a back wire insertion or back wire insertion. The opening 540 is advantageously located in the extension of the conductor insertion channel 501 on the opposite side seen in this conductor insertion direction of the terminal point 1011, ie behind the terminal point 1011. Thus, a conductor also inserted from the back of the terminal 2000 in this and securely clamped in the terminal 1011. In this way, the applications and applications of the terminals according to the invention are further increased, since they are not limited to a one-sided Eznsteckmöglichkeit.

The housing 520 correspondingly formed lid 500 differs from the lid 400 in that the Leitereinführöffnung is closed to the outside, so that the conductor insertion channel 501 is only accessible terminal site. Thus, it is prevented that a back-inserted conductor, which is arranged clamped in the clamping point 1011 and whose conductor end protrudes into the conductor insertion channel 501, protrudes from the clamp 2000 again. In this way, unwanted contacts with an exposed conductor and thus the risk of injury or damage to electronic components are avoided.

In particular FIG. 16 can be seen, the lid 500 preferably has no pusher. In this way, a misoperation of the terminal 2000 can be avoided and the secure clamping of the conductor in the terminal 1011 is guaranteed. To relieve the nip 1011 to introduce a conductor into this or out of this, a tool, such as a screwdriver or a special tool, can be used with the help of which can be pressed from the top of the window 1010 of the spring 1009.

A special tool can advantageously be designed such that it has a handle and a preferably angled guide tip. The leadership tip in turn, preferably has a width which corresponds at most to the width of the guide opening 409, 509, so that the guide tip can be inserted into the guide opening 409, 509 and laterally guided by the guide member 406, 506 during a movement to relieve the nip 1011. The guide tip further has a thickness such that it can be introduced between the first connecting element 407, 507 and the outlet 1020 of the spring 1009 into the guide opening 409, 509 of the guide part 406, 506 and thus engages behind the spring 1009 above the window 1010. The special tool can thus be moved with its guide tip along the guide opening 409, 509 in such a relief movement that this presses down the spring 1010 and thus the nip 1011 is relieved.

However, it is also conceivable that the lid 500 has a pusher, preferably an integrally formed pusher, such as the pusher 404. In this regard, reference is made to the above description.

Figures 17 and 18 show by way of example a terminal block 600, in which terminals 1000 are integrated for the front-side insertion of conductors and terminals 2000 for the rear insertion of conductors.

To assemble a terminal block 600, for example, the individual terminals 1000, 2000 are inserted in series with one another by means of plug-in elements which are introduced into the housings 420, 520 and are corresponding to one another. It is also conceivable that the housing arranged in series of a terminal block 600 in a single housing block 620, comprising a plurality, the housings 420, 520 and their construction corresponding housing portions are manufactured, for example injection molded. The individual housings 420, 520 or housing areas are then equipped with frames 8, 108, 208, 308, 1008 and springs 9, 209, 309, 1009 as well as with the respective covers 400, 500 in accordance with the provided terminal block variant. Thus, numerous terminal block variants can be provided in a particularly simple manner, which are simple in construction, manufacture and assembly and at the same time have a low number of components and costs.

The invention is not limited to the abovementioned limitations. All conceivable embodiments of the embodiments are covered by this application. In particular, the joints, such as grooves, holding webs, Verhakelemente, wells, guide rails and stops, can be configured in any known form, as far as they achieve a secure connection between the housing and cover or housing and housing and their components, and are not on the limited above forms.
