Description

Conductor terminal

The invention relates to a conductor terminal with an insulating material housing, which has at least one conductor insertion opening for insertion of an electrical conductor, and with at least one clamping spring in the insulating housing, which is associated with a conductor insertion opening and a clamping leg, an adjoining the clamping leg spring bow and a to the Federbogen has subsequent spring bow, wherein the clamping leg is designed for clamping an inserted into an associated conductor insertion opening electrical conductor to a built-in insulator housing or insertable terminal contact by spring force of the clamping spring, and wherein the plant leg has an extending in the direction of the terminal contact bearing portion.

Such conductor terminals are used to contact electrical conductors without screws by means of a spring-force terminal with an integral or separate terminal contact of the conductor terminal. The terminal contact may be, for example, a soldered in a circuit board pin, which is inserted into the insulating material. It is also conceivable that the terminal contact is an integral part of the conductor terminal and is electrically connected to a circuit board, an electrical line or a mating connector. Also possible is an electrical (cross) connection by means of a busbar, as e.g. is used in terminal blocks.

DE 34 33 822 A1 discloses a connecting device with an insulating housing, spring devices as a contact device in the housing and a cover closing the insulating material. The spring devices have a clamping leg, which presses an electrical conductor against a busbar with its free end, a spring bow which adjoins the clamping limb and a plant. gift, which rests flat on a busbar. The free end of the abutment leg is bent back in the direction of electrical conductors with S-shaped bend, so that the free end of the abutment leg also presses under spring force the free end of the electrical conductor against the busbar. This S-shaped bent support leg is freely movable to form an S-shaped spring portion for resiliently holding the wire end in a contact position.

A comparable screwless terminal is also shown in DE 197 35 786 A1. Also there, the second contact leg opposite the upper contact leg is bent S-shaped at the free end of the clamping spring. Both contact legs are resiliently designed to resiliently press an inserted electrical conductor against a cover and to fix it.

Also in GB 2 298 973 A, the clamping spring has two clamping legs, wherein the lower clamping leg is bent in turn S-shaped and is accommodated for resilient engagement with the electrical conductor freely movable in the insulating housing.

DE 10 2006 014 646 B4 shows a terminal for printed circuit boards with an insulating housing and a leg spring, the plant leg is angled in an L-shape and on the one hand rests flat on the back wall and on the other hand is held with its free end on projecting arms of a busbar piece and otherwise free in space the insulating material hovers.

JP 2001 -307789 A discloses a conductor terminal with a U-shaped bent leaf spring, whose bearing limb is angled in an L-shape and on the one hand rests flat on a busbar piece on the back of the conductor terminal and on the other hand flat on a bottom plate of a busbar piece designed as a cage. The Base plate and the free end are aligned transversely to the insertion of the electrical conductor. The free end is fixed upward with a likewise horizontally extending fuse block.

DE 20 2010 008 485 U1 shows a connecting device for electrical conductors with a leaf spring, the plant leg is bent partially circular and on the one hand rests flat on a busbar wall on the back and on the other tangent to the bottom plate of the busbar. The partial circular arcuate free end of the leaf spring is freely movable to exert a spring force on an inserted electrical conductor and thereby to increase the clamping force of the leaf spring.

A generic conductor terminal is described in DE 10 2009 035 716 A1. There, a U-shaped leaf spring is installed in an insulating material, wherein the abutment surface rests flat against a bearing wall of the insulating material. When inserting an electrical conductor and possibly also during the actuation of the clamping spring, a force is exerted by the clamping spring on the insulating material, which can deform this. Critical areas are in particular the places where the leaf spring is fixed to the insulating material.

EP 0 472 040 B1 and DE 87 04 494 U1 show conductor terminals in which the contact leg of a clamping spring is supported on a metal carrier.

DE 40 03 701 C2 shows an electrical terminal with at least two conductor terminals per pole, which are installed in a one-piece insulating material.

US 3,138,421 A discloses a conductor terminal with a laterally open and closable with a side cover, one-piece insulating material housing in which a loop-shaped clamping spring is inserted. From DE 10 2010 025 930 A1, a connection terminal with a two-part insulating material housing is known. The clamping spring is inserted with its spring bow in a trough of the conductor lead opening having the main part and stored there. This trough is located below the conductor entry opening. The adjoining the spring bow plant leg is otherwise punctually on a extending in Leiteransteckrichtung web selectively with its perpendicular to the Leiterereinsteckrichtung extending free end.

DE 10 2006 005 260 A1 shows an electrical terminal with a right angle bent clamping spring which has at its two opposite ends in each case a clamping leg. The right angles to each other ver-rising abutment against each lie against a wall of a one-piece, laterally open insulating housing.

From US 2009/0258546 A1, a terminal block with a one-piece, laterally open insulating housing is known, in which a leg spring is used. The leg spring rests with its adjoining the spring bow plant leg on an obliquely to Leitereinsteckrichtung aligned wall of the insulating material.

Object of the present invention is therefore to provide an improved conductor terminal, in which the power dissipation is improved by the clamping spring on the insulating material.

The object is achieved with the conductor terminal with the features of claim 1. Advantageous embodiments are described in the subclaims.

In a generic conductor connection terminal, it is proposed that the contact section be at least partially oblique to the extent direction of the terminal contact extends and is superimposed in these obliquely to the direction of extension direction of the connection terminal extending areas on the insulating material. For this purpose, the abutment leg extends from the spring bow and the abutment against the insulating housing on the first section parallel to the extension direction of the associated terminal contact and adjoins this first section an obliquely to the direction of extension of the associated terminal contact angled area, which on an inclined surface of the insulating material is superimposed.

By an obliquely to the direction of extension of the terminal contact and thus obliquely to the conductor insertion opening of the extension direction of the electrical conductor aligned in the insulating housing abutment is when deflecting the clamping leg of the clamping spring (especially when inserting an electrical conductor or upon actuation of the clamping spring), the force exerted on the clamping force evenly derived the insulating material. This prevents punctual loads on the insulating material housing, which can lead to housing breaks. In contrast to a horizontal support transversely to the conductor insertion direction and the extension direction of the terminal contact succeeds by an obliquely extending to this plant section a uniform force distribution on the insulating material.

The insulating housing is preferably multi-part and has a first, the conductor insertion opening having the main part and at least one of the main part on the side opposite the conductor insertion opening, closing the lid part. In this case, the cover part has a contact surface running obliquely to the extension direction of an associated connection contact for bearing on the at least one region of the contact section extending obliquely to the extent of the connection contact. Due to the bearing of the inclined bearing portion on a correspondingly inclined contact surface of a cover part The force of the clamping spring is derived on the lid part, which thus assumes a supporting function. The lid part also serves as an assembly aid to guide a prestressed clamping spring inserted into the main part into the end position.

Preferably, a free end section then adjoins this angled region at a further angle, which extends to a bearing edge of the insulating housing and abuts with its end against the bearing edge. In this way, the contact leg of the clamping spring is supported on the one hand by the inclined surface of the insulating material. On the other hand, the clamping spring is wedged with the free end portion by the bearing edge of the insulating material, so to speak. Due to the angling of the free end region to the inclined surface, a force discharged onto the bearing edge is then resiliently intercepted by the free end and a shock load is avoided.

In an optional embodiment, the abutment portion has a multiply bent portion which has at least two regions extending obliquely to the extension direction of the terminal contact. This multiply bent portion may for example be bent in an S-shape. The insulating material housing in this context has a support for at least one of these obliquely extending to the extension direction of the terminal contact areas. The multiply bent portion is thereby not free to move and thus does not contribute as a clamping leg for clamping the electrical conductor. Rather, a force acting on the Isolierstoffgehäuse acting upon insertion of an electrical conductor and the clamping on the insulating spring force is better absorbed by reducing the load on the insulating material by the multiply bent portion. The embodiment leads to a relatively long clamping spring with improved spring properties and to an increase of the contact surface on the insulating housing, whereby the power dissipation is equalized and a reduction of mechanical stresses of the insulating material leads.

In a correspondingly S-shaped abutment portion, the insulating housing with a correspondingly adapted curved contour to form a support immersed in at least one bend of the S-shaped portion of the abutment portion.

The conductor connection terminal may optionally have a movably mounted actuating element for opening a clamping point formed by the clamping legs of the clamping spring and the connection contact for clamping an electrical conductor. This actuator then acts on actuation to open the nip with the clamping legs together and is designed and stored accordingly. Such an actuator, for example, a slidably mounted in the insulating housing actuating slide or z. B. also be a rotatably mounted actuating lever.

In a preferred embodiment, at least one connection contact is installed in the insulating housing, which together with the clamping leg of the clamping spring forms a clamping point for the conductor to be connected. The insulating housing also has a contact pin / insertion opening for insertion and opposite to the clamping leg electrically conductive contactable contact pin with the terminal. The connection of the preferably movably mounted in the insulating housing terminal contact thus serves as an electrically conductive intermediate element which is arranged at an inserted and clamped electrical conductor between the electrical conductor and the contact pin. The electrical conductor is thus pressed over the clamping leg of the clamping spring against the terminal contact, which in turn comes into contact with the insertable through the insertable into the contact pin insertion opening pin. Such a separate contact pin, for example, a soldered onto a circuit board pin or a Plug contact pin to be a mating connector. The connection contact can also z. B. be introduced via the contact pin insertion opening in the insulating material and contact directly without intermediate plate with an electrical conductor. Thus, a separate contact pin form the connection contact.

In this context, it is advantageous if the contact pin has a contact projection. In this way, the contact between the contact pin and the connection contact designed as an intermediate plate is concentrated on the contact projection and thus the current transition is improved.

The invention will be explained in more detail by means of embodiments with reference to the accompanying drawings. Show it:

FIG. 1 shows a perspective sectional view of a first embodiment of a conductor connection terminal 1 in the sectional view. The conductor connection terminal 1 has a two-part insulating material housing 2 with a main part 3 and with a cover part 4 closing this at the underside. The cover part 4 is latched to the main part 3. It can also be seen that a clamping spring 5 is installed in the insulating material housing 2. This clamping spring 5 has a clamping leg 6, which is provided to clamp an electrical conductor with its free end to a terminal contact 7. This terminal contact 7 is movably installed in the illustrated embodiment in the insulating 2. The connection contact 7 has a protrusion 8. In the illustrated embodiment, the free end of the clamping leg 6 without plugged electrical conductor 12 in the position shown against the protrusion 8 and is fixed in position there. When plugged in electrical conductor 12, this is clamped between the free end of the clamping leg 6 and the protrusion 8, so that the force of the clamping spring 5 is concentrated on the protrusion 8. Thus, the current transfer values when clamping an electrical conductor 12 are improved.

At the clamping leg 6, a spring bow 9 connects. The spring bow 9 then goes over into a plant leg 10. This plant leg 10 extends from the spring bow 9 from initially parallel to the main extension direction of the terminal contact 7 or the predetermined by a conductor insertion opening 1 1 in the insulating 2 Leitereinsteckrichtung L for an electrical conductor to be clamped 12th From this perpendicular downward in Leiterereinsteckrichtung L directed portion of the support leg 10 is then in an obtuse angle (> 90 °) an oblique to the extension direction of the terminal contact 7 and obliquely to the conductor insertion direction L extending portion 13 of the abutment leg 10 from. This obliquely extending portion 13 is supported on a corresponding oblique contact surface 14 of the cover part 4. Due to the oblique arrangement of the region 13 and the contact surface 14 of the cover part 4, a force exerted by the clamping spring 5 on the insulating 2 force upon actuation of the clamping spring 5 is uniformly intercepted by the insulating housing 2.

The clamping spring 5 is fixed in position in the insulating housing 2 received by the fact that at the obliquely to the extension direction of the terminal contact 7 extending region 13 at a further angle a free end portion 15 of the support leg 10 is connected. The free end of the free end section 15 is introduced into a bearing edge 16 of the insulating housing 2, in particular of the main part 3. Due to the bending between the obliquely extending to the extension direction of the terminal contact 7 supported area 13 and the free end portion 15 ensures that the free end portion 15 can be fixed by spring force in the bearing edge 16. Upon application of force to the clamping spring 5, a force acting on the clamping spring 5 is then absorbed via the inclined contact surface 14 of the cover part 4. The residual force acting on the bearing edge 16 is absorbed in the region of the insulating material housing 2 which is very stable there.

The bearing edge 16 may optionally be present in a pocket, which receives the free end portion 15 and this fixed in position before a dodge in the direction of connection contact 7 and on the other hand from dodging to the connection contact 7 opposite side. The kink between the inclined portion 13 and the free end portion 15 acts as overload protection for the clamping leg 6, which abuts in the sketched deflected position on the kink. Optionally, with a shorter length of the clamping leg, the obliquely extending region 13 or, in the case of a longer clamping leg, the free end section 15 can serve as such an overload protection. In addition, the free end portion 15 extending also obliquely to the conductor insertion direction L serves as a ramp for the electrical conductor to be clamped in order to guide it in the direction of terminal contact 7.

It will also be clear that, in order to open the clamping point formed by the clamping spring 5 and the connection contact 7 for an inserted conductor 12, an actuating element 17 is slidably installed in the insulating material housing 2. The actuating element 17 acts on a free operating end 18 on the vaulted in this area clamping leg 6. The actuating element 17 is secured by a spring tab 19 of the insulating housing 2 on this and protected from falling out.

On the side of the terminal contact 7, which is opposite to the clamping spring 5, a contact pin insertion opening 20 is inserted into the insulating housing 2. This contact pin insertion opening 20 is open on the side opposite to the conductor insertion opening 11. In this way, a contact pin 33 on the bottom, d. H. via the side of the lid part 4, are inserted into the contact pin insertion opening 20. The contact pin 33 is then contacted by the tiltable movable in Isolierstoffgehäuse 2 terminal 7 electrically conductive. The force of the clamping spring 5 acts via an inserted and clamped electrical conductor on the terminal contact 7, which in turn is pressed against the contact pin 33.

Figure 2 omits a side sectional view of the conductor terminal Figure 1 recognize. From this it is further clear that the terminal contact 7 seen in Leitereinsteckrichtung L below the projection 8 one of the clamping spring 5 opposite protrusion 21 and in the lower region another also in the contact pin insertion opening 20 protruding protrusion 22 has. Through these two protrusions 21, 22 defined contact points for electrically conductive contacting of the terminal contact 7 are fixed with a contact pin 33.

It can be seen further that the terminal contact 7 on the side opposite to the contact pin insertion opening 20, grooves 23, with which the connection of an electrical conductor 12 is improved. In particular, the grooves help to keep an inserted electrical conductor 12 even more secure in the conductor terminal 1.

FIG. 3 shows a perspective view of the conductor connection terminal 1 from FIGS. 1 and 2 from the rear side without the cover part 4. It is clear that the free end of the free end portion 15 rests under spring force in the L-shaped bearing edge 16 of the main part 3 of the insulating housing 2. As a result, the clamping spring 5 between the bearing edge 16 and the rear side wall of the insulating material 2, which is opposite to the terminal contact 7, held in the insulating housing 2.

Furthermore, it is clear that the lower protrusion 22 of the terminal contact 7 is formed as an impression in the terminal contact 7. Here, material of the terminal contact 7 is pushed out to form the protrusion 22 in the forming process, so as to form a contact tip.

FIG. 4 again shows the conductor connection terminal 1 from FIGS. 1 to 3 without the cover part 4. It is clear that a detent recess 24 is provided on the rear side wall of the insulating housing 2, in which a corresponding latching projection of the cover part 4 is immersed to lock the cover part 4 to the main part 3. One over the obliquely extending portion 13 of the abutment leg 10 acting on the cover part 4 force is then derived from the cover part 4 on the one hand flat on the main part 3 and on the other hand on the detent recess 24 evenly over the part-circular contour of the detent recess 24.

The conductor connection terminal 1 may consist of any number of adjacently and / or adjacently arranged connection regions for electrical conductors 12. For example, the conductor terminal 1 can be single-pole with only a single clamping spring 5. It is advantageous, however, if multipolar variants are present in which a plurality of clamping springs 5 are installed side by side in the manner shown in the insulating 2. The individual clamping springs 5 can then be separated from one another by partitions. For a multi-pole variant of a conductor terminal 1, a separate cover part 4 can be provided approximately for each clamping spring 5. It is advantageous, however, if the insulating material housing 2 is closed with a single cover part 4, to which the forces of the plurality of clamping springs 5 act. Thus, the forces can be better distributed to the cover part 4 and intercepted under reduced load of the insulating material 2 over a large area.

FIG. 5 shows a perspective view of a clamping spring 5 for the previously described conductor connection terminal 1. It becomes clear that the clamping spring 5 has a clamping leg 6, a spring bow 9 adjoining the clamping leg 6 and a contact section 10 adjoining thereto. The contact section 10 is made widened on the section 25 adjoining the spring bow 9. The side bars 25, which form the widening of the section 25, dive into corresponding grooves 35 (see FIG. 4) of the insulating housing 2 in order to keep the clamping spring 5 fixed in position in the insulating housing. The grooves 35 for the side webs 25 'are preferably designed with play, so that the clamping spring 5 can move relative to the insulating material 1 in the area of the contact portion 10. It is clear that adjoins the widened portion 25 at an angle obliquely extending portion 13 for bearing on the cover part 4. At this oblique area is then followed by an obtuse inside angle (> 90 °) again eh away from the opposite clamping leg 6 away free end portion 15 at.

FIG. 6 shows a perspective view of the clamping spring 5 from FIG. 5 from the rear side. This is again clear that the clamping spring 5 is designed substantially U-shaped, wherein the plant leg 10 is not pronounced by right angles angled areas. Rather, the angle between the widened portion 25 and the adjoining inclined portion 13 is bent to rest on the insulating material in an obtuse internal angle of more than 90 ° (preferably about 1 10 ° to 140 °).

As an alternative to the terminal contact 7 in the insulating housing 1, which forms an intermediate part, can be dispensed with the installation of such a terminal contact 7. Then, a contact inserted through the contact insertion opening 20 z. B. contacted in the form of a contact pin 33 directly to an electrical conductor 12 and clamped on the clamping spring 5. It is also conceivable that the terminal contact 7 is installed in the insulating housing 2 in the manner of a busbar fixed in the insulating 2 and a terminal contact z. B. in the form of a protruding from the insulating 2 contact pin. It is also conceivable, however, that the built-in the insulating housing 2 terminal contact 7 is extended such that on the side in the lower region of the cover part 4, a connector for connecting a mating connector is provided.

FIG. 7 shows a side view of the cover part 4 of the insulating housing 2 recognize. It is clear that the cover part on a side wall has a latching projection 26 which dips into the detent recess 24 of the main part 3. It can also be seen that the cover part 4 in the lower region has a projecting platform 27 with a support section 28, which dips into a corresponding contour in the interior of the main part 3 and is preferably supported there. On the opposite side of the support 8, a stop 29 is provided above the platform 27, with which the cover part 4 is secured against slipping out of the main part 3 on the main part 3.

FIG. 8 shows a perspective view of the cover part 4 from FIG. 7 for a two-pole conductor connection terminal. It is clear that of the common platform 27 two bearing blocks 30a, 30b protrude, each having a locking projection 26. Both bearing blocks 30a, 30b have a sloping bearing surface 14 for bearing a sloping portion 13 of an associated clamping spring. 5

In the space between the bearing blocks 30a, 30b projects a divider 31 from the common platform 27.

FIG. 9 shows a second embodiment of a conductor connection terminal 1 in a sectional view in the detail. In this embodiment, the insulating housing 2 is configured comparable to the first embodiment. In this case, however, the abutment leg 10 is bent S-shaped in its free end region, so that a plurality of regions 13 extending obliquely to the extension direction of the connection contact 7 are created. A bearing block 30c of the cover part 4 dives with a bulge adapted thereto in such a bend to set the S-shaped bent contact portion 10 and intercept forces acting on the inclined portions 13 of the clamping spring 5 and transmitted to the insulating 2 as evenly as possible , It is also clear that a material flap 32 is bent out of the section of the contact section 10 which extends downwards in the conductor insertion direction L and adjoins the spring bow 9. This material flap 32 dips into the main part 3 of the insulating housing 2 in order to fix the clamping spring 5 to the insulating housing 2.

It can also be seen that in the state deflected downwards in the conductor insertion direction L, the clamping leg 6 abuts in an end position against the free end section 15 of the S-shaped bent region of the abutment leg 10. As a result, an overload protection is provided, wherein the force is transmitted to the lid part 14 via the inclined areas 13.

It is also clear that the oblique portion 13 serves as overload protection for the clamping leg 6, which abuts in the sketched deflected position of the inclined portion 13. In addition, the obliquely extending portion 13 serves as a ramp for the electrical conductor to be clamped in order to guide it in the direction of connection contact 7.

Incidentally, reference may be made to the comments on the first embodiment.
