Definitions

  • DE 202 10 105 U1 describes an electrical connection terminal with a contact insert for an insulating housing, with a clamping spring being suspended in the contact insert.
  • a first contact point is formed by the contact insert and a clamping leg of the clamping spring and a second contact point by the contact leg of the clamping spring and the contact insert, with electrical conductors being held fixed in the contact points for electrical contacting.
  • DE 102 61 536 B4 discloses a contact element, the contact element having two recesses for the insertion of electrical conductors.
  • the electrical conductors are held fixed to the contact element by a clamping spring.
  • the clamping spring has a clamping section at each of its ends, the clamping spring being guided through a further opening in the contact element and thus fixing the clamping spring in its position.
  • DE 10 2015 107 853 A1 discloses a clamping spring for connecting an electrical conductor and a contact pin, a busbar element for electrical contacting being arranged between the electrical conductor and the contact pin.
  • the clamping spring has a clamping limb which is set up for clamping the electrical conductor to the conductor rail, the clamping limb extending into a spring bow and a contact limb.
  • the contact leg is bent parallel to the contact pin in order to clamp it to the busbar element.
  • the clamping leg and the contact leg work together in such a way that when the electrical conductor is inserted, the busbar piece is pressed in the direction of the contact pin and when the contact pin is inserted, the busbar piece is pressed in the direction of the electric conductor.
  • DE 10 2011 051 536 A1 discloses a connection element with an insulating material housing, a busbar, a clamping spring for contacting an electrical conductor and a pin contacting element for contacting a pin contact, the pin contacting element being connected to the busbar via a connecting section and extending parallel to the busbar.
  • a contact leg of the clamping spring is mounted on a protruding leg of the busbar.
  • DE 10 2010 010 262 A1 discloses a connector with an insulating housing, a busbar and a clamping spring for contacting an electrical conductor.
  • the insulating material housing has a contact pin insertion opening for inserting a contact pin and a conductor insertion opening for inserting one electrical conductor, the busbars being arranged between the electrical conductor to be clamped and the contact pin to be clamped.
  • EP 1 022 808 A2 discloses a conductor connection terminal for electrical conductors with an insulating material housing, a busbar and a cage clamp spring being arranged in the insulating material housing.
  • the cage clamp and the busbar form a terminal point for connecting an electrical conductor above and below the busbar.
  • the insulating material housing has an actuation opening, in which case the terminal points can be opened, for example, with a screwdriver via the actuation opening.
  • the busbar has a contact arc adjoining the contact section, which transitions into a clamping section for contacting the contact pin, with the clamping section and the contact section of the busbar forming a second contact point and a contact point extending from the clamping section of the busbar towards the contact section and the holding section running past the contact section protrudes, wherein the contact leg of the clamping spring is mounted on the holding section of the conductor rail.
  • the conductor with the clamping limb is pressed against the contact section of the busbar, which preferably forms a fixed part of the busbar, and the contact limb of the clamping spring pulls the contact pin over a movable part of the busbar to the contact section of the busbar.
  • the contact pin is thus clamped by the force of the clamping spring between the contact section of the busbar and the part of the busbar that is movable relative to the contact section.
  • a compact connection element which enables an electrical conductor and a contact pin to be electrically contacted.
  • the busbar is extended to form a second contact point for the contact pin, with the busbar interacting with the clamping spring in such a way that the busbar can serve as a clamping connection for the contact pin, with the clamping spring being attached indirectly via the bearing of the contact leg of the clamping spring on the Holding section of the busbar is involved in opening and closing the second contact point for the contact pin.
  • the holding portion of the busbar is designed to be movable, so that a displacement of the contact leg of the clamping spring also causes a displacement of the holding portion of the busbar. In this way, the second contact point can be opened and closed by moving the contact leg of the clamping spring.
  • the current path between the connected contact pin and the electrical conductor is extremely short, since both rest on the opposite contact sides of the contact section.
  • the connecting element can have a conductor insertion bevel arranged in the conductor insertion direction of the electrical conductor in the conductor insertion opening toward the first contact point in front of the contact section of the busbar.
  • the contact section of the busbar has a bead or a contact projection on the contact side facing the electrical conductor and/or the contact pin. This has the advantage that the electrical conductor or the contact pin can be introduced into the insulating material housing independently of one another under the same conditions, without the electrical conductor or the contact pin affecting one another.
  • the contact section of the busbar is fixed in position or is arranged with limited mobility in the insulating housing.
  • the free end of the contact section of the busbar can be guided, for example, through a first through-opening in the holding section of the busbar, the contact section thereby being held fixed in its position.
  • the contact section of the busbar it is also conceivable for the contact section of the busbar to have configurations within the insulating material housing, such as a clamping edge in the insulating material housing can be kept fixed.
  • the limited mobility of the contact section of the busbar means that the inserted electrical conductor or the inserted contact pin does not interact with the contact section in such a way that the busbar moves within the insulating housing. In this way, the electrical conductor and/or the contact pin can repeatedly come to rest in the insulating housing under the same conditions.
  • a contact lug protrudes from the clamping section, the contact lug being designed for the insertion and pressing of the contact pin at the second contact point.
  • This has the advantage that the contact pin can be held optimally fixed to the contact section of the busbar in a simple manner by the contact lug, for example by the contact lug being adapted to the configuration of the contact pin.
  • a uniform distribution of pressure on the contact pin can be achieved and thus a punctiform loading of the contact pin can be avoided.
  • the free end of the contact leg of the clamping spring can be hooked into a second through-opening, delimited by a transverse web, in the holding section of the busbar.
  • a simple mounting of the contact leg on the busbar can be provided, with the movable holding section of the busbar being displaced by the contact leg of the clamping spring in the direction of the clamping spring and fixing of the contact pin at the second contact point being able to be achieved.
  • a compact connecting element for example in the form of a lever-operated connecting terminal
  • a contact pin and an electrical conductor can be provided which enables electrical contacting of a contact pin and an electrical conductor and is designed to save space.
  • connection element can have an actuating element that is movably built into the insulating material housing, the actuating element being coupled to the clamping spring for opening the first contact point. It is also advantageous if the actuating element is an actuating lever which is pivotably mounted in the insulating material housing and protrudes from the insulating material housing.
  • the actuating element of the connection element can have an actuating section, with the actuating section being arranged to the side of the clamping spring and with an actuating contour of the actuating section being in operative connection with the clamping leg and being supported on the contact section. It is also advantageous if the actuating contour has a pin with a circular or part-circular circumference and a V-shaped cutout, with the clamping leg protruding with an actuating section into the V-shaped cutout.
  • an actuating element can be provided which causes the first contact point to be opened and closed by raising or lowering the clamping leg of the clamping spring.
  • the vague term “a” is to be understood as such and not as a numerical value.
  • the insulating material housing can therefore also have additional conductor insertion openings, contact pin insertion openings, busbars and associated clamping springs, for example for a multi-pole connection element.
  • figure 1 shows a side sectional view of a connection element 1 with an insulating material housing 2, the insulating material housing 2 having a conductor insertion opening 3 for inserting an electrical conductor (not shown) and a contact pin insertion opening 4 for inserting a contact pin 5.
  • a busbar 6 is arranged inside the insulating material housing 2 of the connecting element 1, the busbar 6 having a contact section 7 which is arranged between the inserted contact pin 5 and the inserted electrical conductor (not shown).
  • the conductor rail 6 has a contact arc 8 which adjoins the contact section 7 and which merges into a socket section 9 . It becomes clear that the socket section 9 and the contact section 7 of the busbar 6 form a second contact point for contacting the contact pin 5 .
  • a contact lug 10 protrudes from the socket section 9 and is designed for better insertion of the contact pin 5 in the second contact point.
  • the conductor insertion opening 3 and the contact pin insertion opening 4 are arranged on opposite sides of the insulating housing 2 .
  • the conductor insertion opening 3 and the contact pin insertion opening 4 are, for example, on the same side of the insulating housing 2 .
  • the holding section 11 is movably mounted at least in its direction of longitudinal extension.
  • the holding section 11 is limited in its movement at right angles to the contact section 7 by the element 24 which dips into a free space 25 .
  • a clamping spring 13 is arranged inside the insulating material housing 2 of the connecting element 1 , the clamping spring 13 having a clamping leg 14 with a clamping edge 15 oriented towards the contact section 7 of the busbar 6 .
  • the clamping edge 15 of the clamping spring 13 and the contact section 7 (with an inclined inlet and a bead) of the busbar 6 form a first clamping edge for the electrical conductor to be clamped.
  • the clamping leg 14 merges into a spring bow 16 and a bearing leg 17 .
  • a conductor insertion bevel 19 is arranged in the conductor insertion opening 3 of the insulating housing 2 in the direction of conductor insertion towards the first contact point in front of the contact section 7 of the busbar 6 .
  • Such a conductor insertion bevel 19 allows the electrical conductor and/or the contact pin 5 to be inserted independently of one another under the same conditions into the insulating material housing 2, with the electrical conductor and/or the contact pin coming to rest under the same conditions when plugged in repeatedly.
  • the contact section 7 of the busbar 6 can have a bead or contact projection on a contact side of the electrical conductor and/or the contact pin 5, with the contact pin 5 and/or the electrical conductor coming to rest on the contact bead or contact projection when it is plugged in again.
  • the connecting element 1 has an actuating element 20 , the actuating element 20 being an actuating lever 20 which is pivotably mounted in the insulating material housing 2 and protrudes from the insulating material housing 2 .
  • An actuating section 21 is arranged laterally next to the clamping spring 13 on the actuating lever 20 .
  • the actuating section 21 has an actuating contour which is in operative connection with both the clamping leg 14 and the contact section 7 .
  • the actuating contour can have a part-circular pin with a V-shaped cutout 22 in its circumference, with the clamping leg 14 protruding with an actuating section into the V-shaped cutout 22 .
  • figure 2 shows the connecting element 1 figure 1 in a partial sectional view of the back with the contact pin insertion openings 4, with a part of the insulating material housing 2 being cut free for the sake of clarity.
  • a contact pin insertion opening 4 of the insulating material housing 2 for inserting the contact pin 5 can be seen.
  • the clamping section 7 is passed through the through opening of the holding section 11 for fixing the position of the contact section 7 in the insulating housing 2 .
  • the contact pin 5 is pressed against the contact section 7 by the clamping section 9 , the holding section 11 projecting orthogonally from the clamping section 9 in the direction of the contact section 7 and passing the contact section 7 .
  • the free end 18 of the contact leg 17 of the clamping spring 13 through the same through-opening of the Holding section 11 is passed through, the second through-opening being delimited by a transverse web 23 of the holding section 11 .
  • the holding section 11 rests with its transverse web 23 on the contact leg 17 of the clamping spring 13 .
