Definitions

  • the present invention relates to an electrical connection device with a housing in which at least one contact element can be placed.
  • the object of the present invention is in specifying an electrical connection device with which an electrical line is safe and at a defined Position can be contacted with the contact element.
  • the electrical Line is insertable with respect to the contact element to be positioned so that reliable and defined contacting is feasible. That also arranged in the housing rotatable lever element, which with its short lever arm into the Housing engages and that on its long lever arm from outside the housing is actuated, allows the Safe and defined contacting of the electrical line with the contact element with relatively little effort can be effected by actuating the long lever arm the short lever arm the guide element against the contact element presses, the contact element in the contacting recess engages and thus one in the insertion hole of the Guide element introduced electrical line contacted.
  • the short lever arm of the lever element is designed as an eccentric the long lever arm increases exerted on the guide element with the short lever arm Force is essentially linear. This is due to the The fact that depending on the effective section, i.e. depending on sector of the eccentric bearing against the guide element, due to due to the changing radius of the eccentric the effective length of the short lever arm the aspect ratio of the two lever arms changes. With a trained as an eccentric short lever arm of the lever element is a particularly energy-saving pressing on the guide element the contact element possible. It is also through the eccentric the long lever at its base, so near the pivot point the lever element reinforced, so that the risk of Breaking off the long lever arm is reduced.

  • the electrical connection device When the electrical connection device according to the invention at least one of the side surfaces of the housing is a positive locking element or has a positive connection, it is advantageously possible, the electrical connection device mechanically detachable with its housing e.g. with a a corresponding positive connection or a corresponding Form-locking element having electrical device to which potentials by means of the connecting device according to the invention or signals are introduced to releasably connect.
  • the electrical connection device according to the invention is above can be cascaded in addition or alternatively, if at least one of the side surfaces of the housing is a Has positive locking element and if the at least one Side surface opposite side surface a corresponding Has positive locking. It is then advantageous possible several of the electrical according to the invention Connectors to an electrical connector block assemble and thus related electrical Lines with their respective connection device easy to handle.
  • the connecting device according to the invention in the rear area the insertion hole is at least partially less than in Area of the insertion opening, it is advantageously possible in the guide element electrical lines with different Introduce cross section while doing this electrical Contact lines at a defined position.
  • the contact element e.g. a first cutting element for a large one Cross section and a second cutting element for a smaller one Has cross section.
  • a contact of the electrical wire with a large cross section with the cutting element for the small cross-section would also damage the conductor of the electrical line itself, while trying to use an electrical conductor small cross section with a cutting element for a large one Cross-section contact, often not a satisfactory one electrical contacting is achievable.
  • the cross section of the insertion hole of the guide element at least in parts in the rear area of the insertion hole is less than in the area of the insertion opening in this rear area of the insertion hole only electrical Lines with a correspondingly small cross-section introduce. Electrical cables that are due to their Cross section in this section of the insertion hole is not more are introduced by a contact element in the contacted the front area of the insertion hole; Cables, which also insert into the rear area of the insertion hole leave, at least in the rear area of the insertion hole contacted by the corresponding contact element.
