- 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 contact element has at least one cutting element and the cutting element when pressing the long one Lever arm pressing the guide element against the contact element engages in the contacting recess, is a safe and defined contacting of electrical Lines leading into the insertion hole of the guide element are introduced, also for electrical cables Insulation in the connection or contact area not beforehand was removed, possible.
- the cutting element separates the insulation of the electrical in a manner known per se Line and thereby makes electrical contact at the same time conductive the otherwise enclosed by the insulation Management.
- two contact elements can be placed and in the housing two guide elements are insertable, it is advantageously possible two electrical lines that can each be inserted into one of the two guide elements, by means of the electrical connection device e.g. with a electrical device.

- 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.
- the connection device AV has a housing GA in which the two contact elements KES are placed (examples with others Number of contact elements KES and corresponding corresponding according to other mechanical and electrical elements the following description are also conceivable.).
- the two guide elements are also in the housing GA FE introduced.
- the guide elements FE have an insertion hole with an insertion opening FEE.
- In the insertion hole of the guide elements FE are electrical lines EL ', EL' 'introduced, being in the first guide element FE an electrical line with a large cross section EL 'and in the second guide element FE has an electrical line small cross section EL '' is introduced.
- a rotatable Lever element HE with an eccentric in the exemplary embodiment HEK trained short lever arm HEK and a long lever arm HEL arranged.
- the short lever arm HEK it works Lever element HE in the housing GA of the electrical connection device AV on, with the lever element HE on the long lever arm HEL can be actuated from outside the housing GA.
- the lever element HE a pin HEZ on, in a corresponding hole in the housing GA engages and acts as the axis of rotation of the lever element HE.
- FIG 2 shows the electrical connection device according to the invention AV from the back, i.e. from the side from which the electrical lines EL ', EL' 'in the insertion hole of the Guide elements FE are introduced.
- Figures 1 and 2 show the lever elements HE in a position in which the guide elements FE in the housing GA of the electrical connection device AV can be inserted or removed from it.
- FIG. 3 shows the electrical connection device AV with actuated Lever elements HE, i.e. the long lever arms HEL der Lever elements HE are up to the provided recesses of the housing GA moves, the short lever arm HEK in in 3 not shown, the guide element FE against the contact element KES presses, making an electrically conductive Contact between the electrical lines EL ', EL' 'and the respective contact element KES is effected.
- actuated Lever elements HE i.e. the long lever arms HEL der Lever elements HE are up to the provided recesses of the housing GA moves, the short lever arm HEK in in 3 not shown, the guide element FE against the contact element KES presses, making an electrically conductive Contact between the electrical lines EL ', EL' 'and the respective contact element KES is effected.
- connection device AV a cuboid, convex outer contour, which is particularly a series similar connection devices allowed.
- the electrical connection device AV according to the invention to at least one of the side surfaces of the housing GA one in FIG. 3 not shown positive locking and at least on one opposite this first side surface of the housing GA second side surface a corresponding positive locking element on. So that the electrical connection device AV cascadable so that functionally or electrically belong together electrical lines EL ', EL' 'together, i.e. in one Block of similar electrical connection devices are manageable.
- connection device AV in a partial exploded view showing the detection the interaction of the mechanical components of the connection device AV inside the housing GA relieved.
- the housing GA has a slot-shaped recess, in which the lever element HE can be inserted.
- the lever element HE is in this recess and thus at least partially inside of the housing GA arranged, whereby for easy placement of the lever element HE either the housing GA in several parts can be formed, or the axis of rotation of the lever element HE acting pins HEZ subsequently by the corresponding one Recess in the housing GA in the lever element HE can be introduced.
- the eccentric HEK of the lever element HE engages in a recess FEA of the guide element FE.
- the FE guide element can only be inserted into the GA housing if the long lever arm HEL of the lever element HE pivoted out of the housing GA is, as shown in FIG 1. Because then it's ins Effective radius of the eccentric HEK inside the housing low.
- the guide element FE can thus in the housing GA be introduced, as shown in FIG 2.
- the guide element FE can therefore face in one direction of insertion translational movement from the housing GA the electrical connection device can no longer be moved.
- the long lever arm HEL of the lever element HE continues in Direction towards the housing GA thus towards the slit-shaped Recess of the housing GA pivoted, so presses effective radius of the eccentric HEK that increases Guide element FE against that also arranged in the housing GA Contact element KES, which in the embodiment cutting elements SE ', SE' 'arranged on the contact element KES in contact recesses FEK of the guide element FE intervention.
- the contact element KES has two Cutting elements SE ', SE' 'on one of an insulating Sheathed electrical line EL ', EL' 'in itself contact in a known manner. Stripping the electrical Lines EL ', EL' 'are therefore not required in this case.
- the guide element FE through corresponding contact recesses FEK shape that one in the area of the insertion hole of the Guide element FE inserted and stripped electrical Line EL ', EL' 'with a correspondingly designed Contact element KES is contacted.
