The present invention has for its object to provide a compact conductor terminal with small outer dimensions. This object of the present invention is achieved by a conductor terminal with the features of claim 1. Advantageous embodiments of the conductor connection terminal are described in the dependent claims.

More specifically, the object underlying the present invention is achieved by a conductor terminal having a housing with a conductor receiving space accessible via a conductor insertion opening for receiving an electrical conductor, wherein the conductor can be inserted into the conductor accommodating space in a conductor insertion direction. The conductor connection terminal further has a current bar arranged in the conductor receiving space for contacting an electrical conductor introduced into the conductor receiving space via the conductor insertion opening. Furthermore, the conductor connection terminal has a clamping spring arranged in the housing with a bearing limb and a clamping leg connected thereto via a bending joint, wherein the clamping spring can be moved between a release position in which an electrical conductor can be inserted and / or run in the conductor receiving space, and a clamping position, in which the clamping legs force applied to an inserted in the conductor receiving space electrical conductor in the direction of the current bar, can be actuated. Furthermore, the conductor connection terminal has an actuating element with a handling section and a clamping section brought into contact with the pressure section, wherein the actuating element parallel to the Leiterereinsteckrichtung between a clamping position and a release position is displaceable, and wherein by transferring the actuating element from its clamping position in its release position of the clamping legs the force applied to the pressure section and the clamping spring is transferred from the clamping position in its release position.

Consequently, then the pressure portion of the actuating element is in contact with the clamping leg of the clamping spring both in the release position and in the clamping position of the clamping spring.

In the clamping position of the actuating element, this protrudes preferably from an end face of the housing. In the release position of the actuating element, this preferably does not protrude from an end face of the housing.

Preferably, the bending joint of the clamping spring is deformed by transferring its clamping position in its release position such that the plant leg and the clamping leg of the clamping spring in its release position a smaller angle with each other than in the clamping position of the clamping spring.

The receiving pocket of the actuating element can also be referred to as a clamping spring receiving pocket. The receiving pocket defines a clamping spring receiving space within the actuating element.

The receiving pocket of the actuating element is preferably formed by two side walls, a rear wall arranged between the two side walls and a top wall of the actuating element.

Preferably, the conductor terminal is designed such that the clamping spring is at least partially disposed in the receiving pocket, at least in the release position of the actuating element.

Preferably, in the release position of the actuating member is a majority, preferably more than 50%, more preferably more than 60%, more preferably more than 70%, more preferably more than 80%, more preferably more than 90%, and even more preferably the whole clamping spring arranged in the receiving pocket of the actuating element.

Further preferably, the conductor connection terminal is formed such that in the clamping position of the actuating element at least the bending joint of the clamping spring is arranged in the receiving pocket of the actuating element.

In the following description, like reference numerals designate like components and like features, so that a description made with respect to a figure with respect to a component also applies to the other figures, so that a repetitive description is avoided. Furthermore, individual features described in connection with one embodiment may also be used separately in other embodiments.

1 shows a three-dimensional view of a conductor terminal according to the invention 1. The conductor terminal 1 has a housing 10 which in 1 is shown in partially cutaway form. The housing 10 , which is formed of an electrically insulating material or at least electrically insulating material, has a Leitereinführöffnung 11 on top of which a ladder reception room 12 of the housing 10 is accessible. An in 4 shown and not shown in the other figures electrical conductor L is via the conductor insertion opening 11 in the conductor receiving space 12 insertable by the electrical conductor L in a conductor insertion direction R in the ladder reception room 12 inserted or inserted.

The conductor connection terminal 1 furthermore has a current bar arranged in the conductor receiving space 12 20 on, for contacting a via the Leitereinführöffnung 11 in the ladder reception room 12 introduced electrical conductor L is trained. In the illustrated embodiment, the current bar is 20 U-shaped and has a back wall 21 and two side walls connected to the rear wall 21 22 on. The current bar 20 is made of an electrically conductive material, for example of a steel sheet. The current bar 20 is also electrically connected to a further electrical contact device, such as an electrical contact pin and / or an electrical contact socket, wherein the further electrical contact means is not shown in the figures.

In the case 10 is also a clamping spring 30 arranged. The clamping spring 30 is in 1 not visible, but is in the 3A . 3B and 4 together with an actuator 40 shown in a side sectional view. The clamping spring 30 has a plant leg 31 and a clamping leg 32 on, with the plant leg 31 with the clamping leg 32 is connected via a bending joint 33. The clamping spring 30 is between one in the 3B and 4 shown release position and a in 3A shown clamping position operable. In the release position of the clamping spring 30 is an electrical conductor L in the ladder reception room 12 and / or executable. In the clamping position of the clamping spring 30 the clamping legs 20 are subjected to force in the conductor receiving space 12 inserted electrical conductor L in the direction of the current bar 20 , more specifically towards the back wall 21 the current bar 20 , The clamping leg 32 protrudes in the clamping position of the clamping spring 30 continue towards the back wall 21 the current bar 20 as in their release position.

From the 3A and 3B it can be seen that the bending joint 33 the clamping spring 30 by transferring their in 3A illustrated clamping position in the in 3B shown release position is deformed such that the plant leg 31 and the clamping leg 32 the clamping spring 30 in their release position a smaller angle with each other than in the clamping position of the clamping spring 30 ,

The conductor connection terminal 1 also has an actuating element 40 on, that a handling section 41 and a pressure section 42. Like from the 3A . 3B and 4 it can be seen, is the printing section 42 with the clamping leg 32 in contact. The actuator 40 , also as a pusher element 40 or as a pusher 40 may be referred to, is in the housing 10 slidably arranged. The displacement of the actuating element 40 takes place parallel to the conductor insertion direction R between a clamping position of the actuating element 40 and a release position of the actuator 40 , In this case, by transferring the actuating element 40 from his in 3A shown clamping position in its in 3B shown release position of the clamping legs 32 the clamping spring 30 by means of the printing section 42 so kraftbeaufschlagt that the clamping spring 30 is transferred from the clamping position in the release position.

Out 1 it can be seen that in the clamping position of the actuating element 40, this from an end face of the housing 10 protrudes. In the release position of the actuating element 40 this preferably does not protrude from the front side of the housing 10 out.

From the 3A . 3B and 4 it can be seen that the handling portion 41 of the actuating element 40 and the flexure joint 33 the clamping spring 30 are arranged to one another such that a connecting line of the handling section 41 to the bending joint 43 parallel to the conductor insertion direction R runs. Consequently, a displacement of the actuating element takes place 40 parallel to the plug in direction R ,

The actuator 40 has a receiving pocket 43 for receiving the clamping spring 30 on. The receiving pocket also to be designated as a clamping spring receiving pocket 43 43 defines a clamping spring receiving space 43 within which the clamping spring 30 at least partially receivable. In particular from 2 B It can be seen that in the illustrated embodiment, the receiving pocket 43 is formed by two side walls, a rear wall disposed between the side walls and a top wall of the actuating element 40.

How out 3A it can be seen, is in the clamping position of the actuating element 40 and consequently in the clamping position of the clamping spring 30, the bending joint 33 the clamping spring 30 received or arranged in the receiving pocket 43. By transferring or depressing the actuating element 40 in the in 3B shown release position is the clamping spring 30 continue in the receiving bag 43 accommodated, so that in the release position of the actuating element 40 and consequently in the associated with this release position of the clamping spring 30 these to a large extent in the receiving bag 43 recorded or arranged.

In the illustrated embodiment, the actuator 40 has two slide rails 44 on, each at a sliding edge 23 of the current bar 20 issue. Here are front edges 23 the side walls 22 of the current bar 20 as sliding edges 23 educated. Upon a displacement of the actuating element 40 between the clamping position and the release position slide the slide rails 44 along the sliding edges 23 so that a guide of the actuator 40 through the current bar 20 he follows.

The housing 10 also has two guide grooves 13 on, in each of which a leadership rib 46 of the actuating element 40 slidably arranged. Consequently, the actuator is 40 over the guide grooves 13 and the guide ribs 46 guided displaceable between the clamping position and the release position.

Furthermore, the actuating element 40 two holding surface 47 on, the falling out of the actuator 40 out of the case 10 prevent. For this purpose, preferably still in the figures, not shown end cap on the housing 10 put on, the falling out of the actuator 40 prevented by the retaining surfaces 47 abut against a holding device arranged in the end cover (eg in the form of further holding surfaces or retaining projections) as soon as the actuating element 40 threatens to leave the housing 10 to slide.

As can be seen from the figures, the actuator 40 further includes a conductor receiving space 12 oriented conductor receiving trough 45 on. Due to the provision of the conductor receiving trough 45, the entire conductor terminal builds 1 more compact, since a distance between an inserted into the conductor receiving space 12 electrical conductor L and the actuator 40 can be downsized. Furthermore, an insertion of an electrical conductor L in the ladder reception room 12 simplifies, as the electrical conductor L also by the in the actuator 40 provided conductor receiving trough 45 when inserted into the ladder receiving space 12 to be led.
