Definitions
- the invention relates to a conductor connection terminal with an insulating material housing, where the insulating material housing has a conductor insertion opening for inserting an electrical conductor in a conductor insertion direction, with a busbar and with a clamping spring, the clamping spring having a clamping leg which, together with the busbar, forms a clamping point for the electrical conductor forms, and with an actuating element, wherein the actuating element is slidably mounted in the insulating housing and has an actuating portion and a sliding portion, wherein the actuating portion is designed to open and / or close the terminal point.
- DE 102015 101 893 A1 discloses a conductor connection terminal with a busbar and a clamping spring, with the busbar and the clamping spring forming a clamping point for an electrical conductor to be clamped.
- the clamping point can be opened by an actuating element mounted in an insulating material housing, the actuating element interacting with a contact leg of the clamping spring.
- a recess is arranged on the actuating element, with a projection of the busbar being accommodated in the recess.
- the actuating element has a guide pin, the guide pin being displaceably mounted in a guide contour of the insulating material housing in the direction of conductor insertion.
- the actuating element can be guided from an initial position into an actuating position and back.
- the initial position is the position in which the clamping point is completely closed.
- the operating position is the position in which the clamping point is completely open, with the electrical conductor being able to be inserted into the conductor connection terminal.
- a sliding section is arranged on the actuating element, in which case a sliding actuation can be provided.
- a sliding actuation By training the sliding section and mounting it on the outside of the insulating housing, the user can move the actuating element by shifting the sliding section on the insulating housing.
- an alternative actuation option to a handle actuation is provided, with the actuation element being able to be displaced by the user through the sliding section.
- there is a combined slide-handle actuation so that the user can choose between the slide actuation or the handle actuation, depending on the application.
- the sliding section for moving the actuating element is easily accessible from the outside for the user. This is moved during the actuation process and is easily accessible to the user even when the clamping point is open.
- the actuating element is guided inside the insulating housing, with the actuating element being accessible to the user from the outside only via a smaller pressure surface than the sliding section.
- the actuating element of the handle actuation is mounted within the insulating material housing, so that access for the user is difficult and an additional operating tool may be required to loosen the actuating element.
- the sliding section it is not necessary for the sliding section to rest directly on the insulating material housing. It is conceivable, for example, for the sliding section to be arranged at a distance from the insulating material housing.
- the actuating element is sufficiently stabilized by the guide pin, with simultaneous guidance of the actuating element from the starting position to the actuating position being able to be guaranteed.
- the guide pin can be arranged, for example, on the sliding section of the actuating element.
- the actuation section can be operatively connected to the clamping leg of the clamping spring in order to open and/or close the clamping point.
- the actuation section is in particular the section that can interact with the clamping spring in such a way that the actuation section bears against the clamping leg to open the clamping point.
- the clamping leg is shifted into an open position by the actuation section, so that the electrical conductor can be inserted into the conductor connection terminal or can be removed from the conductor connection terminal.
- the guide contour can be designed as an elongate recess, the guide contour being designed in such a way that the guide pin is held in a holding position in an open position and/or closed position of the clamping point.
- a trough can also advantageously be arranged in the guide contour, where the guide pin is held in an open position and/or closed position of the clamping point in the trough.
- a spring force of the clamping leg can act on the actuation section in such a way that the actuation element is tilted into a holding position.
- the Actuate supply element is held in the holding position without external influence, so that the electrical conductor can be inserted into or removed from the conductor terminal.
- a projection is arranged on the guide contour, where the projection makes it difficult to move the guide pin or the actuating element in such a way that an increased force has to be applied, since the guide pin can be used to guide past this projection. It is possible, for example, that in the starting position the projection makes it difficult to move the guide pin, so that the actuating element cannot be unintentionally moved into an actuating position and release an inserted electrical conductor. However, it is also conceivable that the projection makes it difficult for the actuating element to be displaced in the actuating position, so that the actuating element can be held in the open position of the clamping point.
- both a trough and a projection on the guide contour can be arranged in order, for example, to place the guide pin in an open position of the terminal and in a closed position of the terminal point in a holding position can be held.
- the elongated recess can be designed, for example, as an elongated hole or at least in the manner of an elongated hole, so that the guide pin can be guided in the longitudinal direction of the elongated hole.
- the direction of longitudinal extension is the direction in which the long hole extends with its largest dimension.
- the actuation section and the sliding section can be connected to one another via a connecting web. Further advantageously, the connecting web can protrude essentially perpendicularly from the sliding section in the direction of the actuating section.
- the connecting section can be arranged laterally next to the clamping spring, it being possible for the actuating section to be connected to a sliding section lying outside of the insulating material housing, for example.
- a sliding actuation can be provided in a simple structural manner.
- the connecting web can protrude perpendicularly from the sliding section in the direction of the actuating section.
- the connecting web does not have to protrude exactly perpendicularly from the sliding section.
- a deviation of up to 5 degrees, in particular up to 10 degrees, based on a 360° system, is conceivable.
- the guide pin can protrude from the connecting web transversely to the conductor insertion direction and thus transversely to the deflection direction of the clamping leg.
- transverse means in particular that the guide section protrudes at an angle between 85° and 105°, in particular at an angle of 90°.
- the actuating section can bear against the clamping leg of the clamping spring with an actuating contour.
- the actuating contour is in particular adapted to the contour of the clamping leg of the clamping spring.
- the actuating contour can be designed, for example, as a negative contour of the clamping leg. In this way, the transmission of force from the actuation section to the clamping leg to open the clamping point is further improved.
- the sliding section can be mounted such that it can be tilted about a pivot point.
- a tilting movement takes place in particular as a rotation through a small angle of rotation.
- a pivoting movement takes place around a larger angle of rotation.
- the angle of rotation is greater than 60°. Consequently, the sliding section is tilted by a smaller angle than the sliding section is pivoted. Furthermore, no opening and/or closing of the clamping point results from the tilting movement according to the invention.
- the actuating element is transferred into a latching position by the tilting movement about the support point or is moved out of the latching position so that the actuating element can be held in an open position of the terminal point.
- the pivoting movement causes the clamping point to open or close.
- the opening and/or closing of the clamping point results from a displacement of the actuating element
- the pivot point can be arranged in the area of the guide pin.
- the sliding section can thus be mounted so as to be tiltable about the guide pin.
- the sliding section is mounted in the open position of the clamping point, ie in the operating position, such that it can be tilted about the pivot point.
- the actuating element can be moved into a latching position, for example in the actuating position, i.e. when the clamping point is open.
- the actuating element can be tilted, for example, by the spring force of the clamping leg, in that the spring force of the clamping leg acts on the actuating section when the clamping point is open in such a way that the actuating element is tilted into the locking position about the pivot point.
- the actuating element In the detent position, the actuating element is held in the actuating position, so that the electrical conductor can be inserted into the conductor terminal.
- the tilting of the sliding section about the fulcrum thus represents a tipping, wherein the tilting is the ro tation about the fulcrum, for example in the latching position.
- the sliding section can stand up obliquely to the insulating material housing, where the end of the sliding section facing the conductor insertion opening protrudes from the insulating material housing.
- the sliding section can, for example, be guided out of the locking position again by rotating it in the opposite direction. This can be done, for example, by applying a force to the end of the sliding section that is away.
- the bearing surface of the sliding section can be designed obliquely. Furthermore, the bearing surface can be V-shaped before geous.
- the distance between the sliding section and the insulating material can be reduced section at least on a part of the sliding. Furthermore, the tilting movement about the pivot point can be further improved as a result, since the geometry of the sliding section is thus adapted to the turning movement or rotation.
- the insulating housing can have a first housing part and a second housing part.
- the sliding section of the actuating element can also advantageously be supported on the first housing part, with the guide contour for guiding the actuating element being arranged on the second housing part.
- the erfindungsge Permitted conductor terminal can be easily assembled by first inserting a contact insert into the first housing part and then terminating the second housing section of the insulating material housing.
- the actuating element can be accommodated captively in the conductor connection terminal, with the guide pin being accommodated in the guide contour in a first assembly step and the second in a second step Housing part closes the guide contour in such a way that the guide pin is captively mounted in the conductor connection terminal.
- the guide contour can also be formed by the first and the second housing part, for example a lower contact contour being formed by the first housing part and an upper contact contour, which is opposite the first contact contour, being formed by the second housing part.
- a reverse variant is also conceivable, in which the guide contour for guiding the actuating element is arranged on the first housing part, with the sliding section of the actuating element being placed on the second housing part.
- the bearing surface can be placed on the outside of the insulating material housing, with the sliding section being set up for manual operation. Furthermore, the bearing surface on the outside of the insulating material housing can advantageously be designed to be slidable.
- sliding friction can thus arise between the bearing surface and the outside of the insulating material housing, with the sliding section being able to slide over the outer surface of the housing.
- the sliding section can also be placed on the outside of the insulating material housing at a distance from it. However, it is also conceivable for the sliding section to be mounted directly on the outside of the insulating material housing.
- the sliding section By being supported on the outside of the insulating material housing, the sliding section remains easily accessible for the user both in the starting position and in the actuating position, whereby the actuating element can thus be guided more easily by the user into the actuating position and back.
- the clamping leg can merge into a spring arc, with the spring arc extending into a contact leg, with the contact leg being able to be fixed to a part of the conductor terminal.
- the contact leg is designed in particular to contact a part of the conductor connection terminal.
- the contact leg is preferably designed for contact with the conductor rail.
- the busbar and the clamping spring can be designed as a self-supporting contact insert. Spring forces of the clamping spring acting on the housing and/or the actuating element can thus be avoided or at least reduced. In addition, no additional components such as fastening elements for fastening the clamping spring are required.
- the indefinite term "a” is to be understood as such and not as a numeral. It is also conceivable that two guide pins are arranged on the actuating element, with both guide pins being displaceably mounted in the insulating housing in a guide contour or in each case in their own guide contour. Wei terhin is conceivable that the conductor terminal is designed as a multi-pole conductor terminal. A 2-pole, a 3-pole or a 6-pole conductor connection terminal with two, three or six corresponding clamping points is conceivable.
