Definitions

  • the present invention relates to a terminal with a Housing, with a connection contact fixedly arranged in the housing, with a spring clip with a first leg, which is arranged on the terminal contact, with a free spring leg that fits over a bend knee in one Terminal end merges, the terminal end a the contact has engaging clamping edge, with a pivotable in the Housing mounted, attacking the spring leg of the clamping spring Actuator, which in a clamped position the spring leg releases so that its clamping end with its clamping edge a conductor inserted into the housing against the connection contact pulls, and in an open position the spring leg depresses so that the clamping edge for inserting a conductor is lifted from the terminal contact, the actuator has a first and a second lever arm with two free ends.
  • Such a terminal is known from DE 196 11 762.
  • the two are in the connection terminal according to DE 196 11 762 Arms of the actuator rigidly connected.
  • On one Arm end can be used from the outside with a tool, for example a screwdriver to be engaged around the actuator to pivot into the open position, one in the housing corresponding opening is provided, which this pivoting of Allows actuator.
  • the end of the other lever arm has a nose which, in the open position, is pivoted so far over the knee is that the actuator is in the open position is held self-locking.
  • After inserting a conductor into the Terminal can be the actuator in opposite To be pivoted to release the travel, thereby the conductor is clamped to the connection contact.
  • This terminal has several disadvantages: Due to the direct contact of the actuating element with the clamping spring, which in turn conductively connects to the connection contact stands, the actuator is to be non-conductive. This is necessary because the actuator is designed from the outside must be accessible and therefore this with senior training would involve the risk of electric shock.
  • the actuator For self-locking of the actuator in the open position the actuator must be pivoted precisely on a pin be stored. Wear of the nose can cause that the self-locking condition is no longer maintained will, d. H. the clamping spring springs back into the clamping position by itself. Because the actuator is exactly on the pin sit, are high demands on the manufacturing tolerances to deliver.
  • this object is achieved in that the first Lever arm is pivotally connected to the second lever arm, wherein a free end of the first lever arm pivotable in the housing is stored, and a free end of the second lever arm with the Spring leg is connected and that the pivotable connection of the first and second lever arm is slidably disposed in the housing.
  • first and second lever arm Store the housing so that its position in the open position is held self-locking. This eliminates the tension the clamping spring through constant application of force from outside, for example with a screwdriver.
  • connection of the first and second lever arm for self-locking via their dead center is pivotable out.
  • the Clamping spring can tension the housing in the swiveling area Connection of the two lever arms an opening for one Have clamping tool.
  • an opening in the housing in the area of the pivotable connection for a clamping device that can be operated from outside the housing provide, the tensioning device being displaceable in the housing stored and can be firmly connected to the housing.
  • such a tensioning device to connect with at least one lever arm such that In addition to tensioning, the clamping spring can also be released by actuation the clamping device is possible.
  • the lever arms are connected to an actuating device, with which the clamping spring can be tensioned and / or relaxed is.
  • the actuating device is particularly advantageous to be arranged in or to the housing in such a way that they are only tensioned Condition of the clamping spring is actuated. This ensures that after inserting a conductor into the terminal, d. H. in the tensioned state of the spring, a relaxation, d. H. a jam of the conductor can be triggered while after clamping the actuator's actuator is no longer accessible and thus an accidental release of the conductor is prevented becomes.
  • the actuating device can be provided in this way to train that it extends out of a first side of the housing, thus, at least in part, around the housing, is led around from another side of the housing is visible and operable.
  • This has the advantage that with a Installation of the connection terminal with the rear side not accessible three work steps can be carried out from one side of the connection terminal are: on the one hand the insertion of a conductor, on the other hand tensioning the spring by inserting a tensioning device or actuating the clamping device provided in the housing and thirdly, triggering the clamping of the conductor by actuation the actuator.
  • the first lever arm can be a pin or a rivet be pivotally connected to the second lever arm.
  • it can also be provided the first lever arm with the second To form the lever arm in one piece, thereby the two lever arms in a cost-effective manner, for example by a plastic die-casting process can be produced in one operation.
  • the connector shown in Figure 1 has a housing Plastic, 10 pins 12 and holes 14 in the housing are provided to several such terminals to one Join the terminal strip together.

  • a first leg 18 a clamping spring 20 lies between part of the contact clip 16 and a retaining projection 22 and is thereby without additional Fasteners held in the housing 10.
  • the clamping spring 20 is U-shaped around the holding projection 22 curved.
  • Above the holding projection 22 there is a free one resilient spring leg 24 of the clamping spring 20 is formed.
  • the front The end of the spring leg 24 is essentially rectangular bent downwards so that a clamping end 26 is formed becomes.
  • the transition of the spring leg 24 into the clamping end 26 is formed by an arc around the front end of the holding projection 22 stoked bend 28 formed.
  • the pinch end 26 has an opening 30 through which the front end 32 of the contact bracket 16 passes through.

While the free end 44 of the first Lever arm 36 is pivotally supported in the housing 10, that is free end 46 of the second lever arm 38 with the spring leg 24 the clamping spring 20 in contact.
  • the free end 44 of the first lever arm 36 and the free end 46 of the second lever arm 38 are rounded trained to slide during pivotal movement in the housing area 48 or on the spring leg 24 of the clamping spring 20 to facilitate.
  • the terminal is the angle ⁇ that the first Includes lever arm 36 with the second lever arm 38, more than 180 °. This angle cannot be exceeded since the first Lever arm 36 on a stop area 50 and the second lever arm 38 rests on a stop area 52 of the housing 10.
  • the spring force of the clamping spring 20 causes one Self-locking, d. H. the clamping spring 20 can not without external Transition to the relaxed state.
  • the security reserves for self-locking can be done by varying the angle the stop areas 50 and 52 are varied.
  • an actuator 54 which with the first lever arm 36 is connected and through a housing opening 57 protrudes from the housing, visible and from the outside actuatable.
