Abstract

A conductor terminal ( 1 ) having an insulating material housing ( 2 ) and having at least one spring-loaded clamping connection ( 11 ) in the insulating material housing ( 2 ) and also having at least one actuation element ( 4 ), which is pivotably accommodated in the insulating material housing ( 2 ) and is designed to open in each case at least one associated spring-loaded clamping connection ( 11 ), is described. The actuation element ( 4 ) has two side wall portions ( 8 a , 8 b ) which are spaced from one another and at least partially enter the insulating material housing ( 2 ) with a pivot bearing region ( 14 ) and, opposite said pivot bearing region ( 14 ), are connected to each other by a transverse web ( 5 ) to form a lever arm. The pivot bearing regions ( 14 ) of the mutually distanced side wall portions ( 8 a , 8 b ) of an actuation element ( 4 ) form an axis of rotation (D), about which the actuation element ( 4 ) is pivotably mounted in the insulating material housing ( 2 ). An associated spring-loaded clamping connection ( 11 ) is at least partially accommodated in the space between the pivot bearing regions ( 14 ) of an actuation element ( 4 ). The pivot bearing regions ( 14 ) have actuation portions ( 16 ), which in each case are designed in order to act on an associated clamping spring ( 17 ) of a spring-loaded clamping connection ( 11 ) as the actuation element ( 16 ) is pivoted from a closed position into an open position, and in that the actuation portions ( 4 ) are arranged on the pivot bearing regions ( 14 ) of the side wall portions ( 8 a , 8 b ) at a distance from one another that is shorter than the distance between the side wall portions ( 8 a , 8 b ). The actuation portions ( 16 ) extend parallel to the side wall portions ( 8 a , 8 b ) and are formed integrally with the side wall portions ( 8 a, 8 b ), such that in each case a guide slot ( 30 ) is provided between an actuation portion ( 16 ) and the associated, directly adjacent side wall portion ( 8 a , 8 b ), and in that a guide web ( 27 ) of the insulating material housing ( 2 ) in each case enters an associated guide slot ( 30 ) for guiding the actuation element ( 4 ) in the event of a pivot motion about an axis of rotation (D) in the pivot bearing region ( 14 ).

First claim

1 . A conductor terminal having an insulating material housing and having at least one spring-loaded clamping connection in the insulating material housing and also having at least one actuation element, which is pivotably accommodated in the insulating material housing and is designed to open in each case at least one associated spring-loaded clamping connection, wherein the actuation element has two side wall portions which are spaced from one another and at least partially enter the insulating material housing with a pivot bearing region and, opposite said pivot bearing region, are connected to each other by a transverse web to form a lever arm, wherein the pivot bearing regions of the mutually distanced side wall portions of an actuation element form an axis of rotation, about which the actuation element is pivotably mounted in the insulating material housing, and wherein an associated spring-loaded clamping connection is at least partially accommodated in the space between the pivot bearing regions of an actuation element, and in that the pivot bearing regions have actuation portions, which in each case are designed in order to act on an associated clamping spring of a spring-loaded clamping connection as the actuation element pivots from a closed position, in which the actuation element is pivoted with its transverse web in the direction of the insulating material housing and a clamping point formed by the spring-loaded clamping connection for clamping an electrical conductor is closed, into an open position, in which the actuation element with its transverse web is pivoted away from the insulating material housing and a clamping point formed by the spring-loaded clamping connection for clamping an electrical conductor is open, and in that the actuation portions are arranged on the pivot bearing regions of the side wall portions at a distance from one another that is shorter than the distance between the side wall portions, wherein the actuation portions extend parallel to the side wall portions and are formed integrally with the side wall portions, such that in each case a guide slot is provided between an actuation portion and the associated, directly adjacent side wall portion, and in that a guide web of the insulating material housing in each case enters an associated guide slot for guiding the actuation element in the event of a pivot motion about an axis of rotation in the pivot bearing region.

2 . The conductor terminal as claimed in claim 1 , wherein the actuation element is coordinated with the insulating material housing and the associated spring-loaded clamping connection in such a way that the lever pivot force acting on the transverse web in order to pivot the actuation element from the closed position into the open position and the spring actuation force acting on the clamping spring by the actuation portions when pivoting the actuation element from the closed position into the open position act on the same side relative to the axis of rotation.

3 . The conductor terminal as claimed in claim 1 , wherein the adjacent side wall portions of two actuation elements arranged adjacently in the insulating material housing border one another directly.

4 . The conductor terminal as claimed in claim 1 , wherein the insulating material housing has a terminal housing part and a separate cover part, wherein the terminal housing part and the cover part are connected to one another in the assembled state by means of the at least one spring-loaded clamping connection, inserted into the terminal housing part, and associated actuation element, and in that the pivot bearing region is accommodated in a space formed between the terminal housing part and cover part.

5 . The conductor terminal as claimed in claim 4 , wherein the terminal housing part and/or the cover part has/have part-circle bearing cavities for pivotably mounting the actuation element in the insulating material housing, wherein a part-circle outer periphery of the pivot-bearing region matched accordingly with the part-circle bearing cavity enters an associated bearing cavity.

6 . The conductor terminal as claimed in claim 1 , wherein the actuation portions have a part-circle outer periphery with a cutout for forming a step protruding in the direction of the center of the actuation portion, wherein the at least one spring-loaded clamping connection in each case has a bus bar and a clamping spring with an actuation tab, and the actuation tab of the clamping spring rests on the step as the actuation element is pivoted in order to open a clamping point formed between a clamping edge of the clamping spring and the bus bar for clamping an electrical conductor.

7 . The conductor terminal as claimed in claim 1 , wherein the side wall portions of an actuation element are connected to one another by means of a transverse web, which, in the state in which the actuation element is pivoted up, in which state the clamping point is open, extends from the free end of the side wall portions to the insulating material housing.

8 . The conductor terminal as claimed in claim 1 , wherein the transverse web protrudes beyond the free end of the side wall portions opposite the pivot bearing region.

9 . The conductor terminal as claimed in claim 1 , wherein two or more spring-loaded clamping connections are accommodated adjacently in the insulating material housing, and in that the spring-loaded clamping connections have a common bus bar.

10 . The conductor terminal as claimed in claim 1 , wherein the pivot bearing regions are mounted on a portion of a bus bar of the associated spring-loaded clamping connection.

11 . The conductor terminal as claimed in claim 1 , wherein the outer contours of the actuation portions lie in the space between the plane spanned by a bus bar of the associated spring-loaded clamping connection and a plane spanned by a contact limb of the associated spring-loaded clamping connection.
