  • connection terminal has a spring element in the form of a tension spring, which draws a connected electrical cable into contact with an associated contact element by means of an elastic spring effect and thus creates a clamped connection between the electrical cable and the contact element.
  • the electrical cable is pushed through an opening in the clamping leg and clamped between the clamping leg and the contact element in the connected position.
  • a locking device is provided by which the clamping leg is in a release position relative to the Housing is locked.

  • the trigger section can be triggered by interaction with the electrical cable so that the locking of the clamping leg with the trigger element is canceled and the clamping leg is thus released from the release position.
  • the connection terminal closes automatically when the electrical cable is plugged in. This results in a simple connection process, with reliable contact between the electrical cable and the contact element due to the clamping effect of the clamping leg.
  • the trigger element is separate from the spring element and is therefore present as a separate element in addition to the spring element.
  • the trigger element is mounted in an adjustable manner relative to the housing, for example pivotable or movable, and can therefore be adjusted relative to the housing to trigger the clamping leg.
  • the trigger element can be made of metal, for example as a stamped and bent part.

If an electrical line 2 is inserted along the If the plug-in connector 120 is inserted into the plug-in opening 100 in the plug-in direction E, the electrical line 2 with an inserted conductor end 20 acts on the trigger section 130 within the receiving space 101 of the housing 10 and adjusts the trigger element 13. This moves the trigger element 13 relative to the clamping leg 120 so that the clamping leg 120 is disengaged from the locking sections 132 on the bearing leg 131 of the trigger element 13 and the clamping leg 120 is thus released from the release position.
  • the clamping leg 120 Due to the elastic spring preload on the clamping leg 120, the clamping leg 120 snaps into contact with the inserted electrical line 2 and clamps it to the contact element 11 so that the electrical line 2 with the (stripped) conductor end 20 is pressed against the contact element 11 and is thus electrically contacted with the contact element 11.
  • the clamping leg 120 forms an adjusting edge 123 on a lateral edge section.
  • the adjusting edge 123 projects axially relative to the clamping section 124.
  • the clamping section 124 in turn projects beyond the adjusting edge 123 (viewed along the elongated extension of the clamping leg 120) and forms the end of the clamping leg 120 for clamping an inserted electrical line 2 and also for locking with the locking sections 132 on the bearing legs 131.
  • the adjusting edge 123 serves to interact with the active section 144 of the actuating element 14.
  • the effective section 144 acts on the adjusting edge 123 and slides along the adjusting edge 123 so that the clamping leg 120 is moved into the release position, as is the case in the transition from Fig. 3A, 3B towards Fig. 4A, 4B is evident.
  • the actuating element 14 acts exclusively on the adjusting edge 123 and thus on one side on the clamping leg 120, in that the active section 144 is in operative connection with the adjusting edge 123. Due to the one-sided arrangement and design of the actuating element 14, the actuating element 14 with the lever section 142 is arranged outside an area of the receiving space 101 into which the electrical line 2 is introduced for connection to the connection terminal 1. This results in an arrangement that is advantageous in terms of installation space.
  • the clamping section 124 forms a clamping edge at its free end, with which the clamping leg 120 clamps the conductor end 20 when the electrical line 2 is connected.
  • the actuating element 14 is used to transfer the clamping leg 120 into the release position from the non-actuated position ( Fig. 3A, 3B ) to the actuated position ( Fig. 4A, 4B ) and thereby moves the clamping leg 120 into the release position in which the clamping leg 120 is locked with the release element 13.
  • the actuating element 14 can be moved back into the non-actuated position in which the actuating section 141 is closer to the housing and, for example, lies flat in an associated receiving opening on the housing 10, as can be seen from Fig.1 is evident.
  • a locking element 145 is formed on the actuating section 141, which in the non-actuated position is in engagement with an associated locking element 103 on the housing 10, as can be seen from Fig. 1 and 2 is visible.
  • the actuating element 14 is thus held in position on the housing 10 in the non-actuated position and thus assumes a defined, rattle-free position on the housing 10 in the non-actuated position.
  • the actuating element 14 can be pivoted in the actuating direction B so that the clamping leg 120 can be moved back into the release position according to Fig. 4A, 4B is transferred.
  • the electrical cable 2 can thus be removed from the connection terminal 1 essentially without force.
  • the release position the clamping leg 120 is again locked to the release section 130, so that when an electrical cable 2 is inserted, this in turn acts on the release section 130 and the locking of the clamping leg 120 is thereby canceled.
  • the electrical cable 2 is thus again automatically connected to the connection terminal 1 with the clamping leg 120 being automatically released.
  • the trigger element is integral and formed in one piece with the spring element.
  • a trigger element can For example, it can also be designed separately from the spring element, for example by a further spring element or by a separate lever.
  • the actuating element is designed to act on the clamping leg of the spring element on one side.
  • the actuating element can also act on the clamping leg of the spring element on both sides at adjusting edges that are located away from one another.
  • the actuating element can be mounted at any location and in any manner pivotably on the housing or on a component that is stationary relative to the housing.
