Definitions
- the invention relates to a terminal block according to the preamble of claim 1.
- a generic terminal block with a penetrating conductor insulation Connection device is known from DE 196 27 209.
- the one shown in this document Connection device has contact cutting with cutting edges that are expand to contact areas.
- the contact surfaces enable a Large-area contacting of the line wire of the connected electrical conductor than the actual contact cutting for cutting the conductor, which the Touch the conductor essentially "line-like".
- the terminal housing is arranged in the terminal housing and / or in one piece with the Terminal housing designed insertion element for inserting the into the terminal housing introduced into the contact cutting edge and / or the contacting area provided and the terminal housing preferably has openings which are dimensioned such that an actuating tool on each side of each conductor how a screwdriver can be guided into the terminal housing, such that by pivoting and / or shifting the actuating tool of the ladder with the insertion element from one side into the contact blade and / or the contact area is feasible and detachable from the other side with or without an insertion element.
- the insertion element is separate, in particular from the metal parts of the connecting element is formed, because in this way a particularly good Guidance of the insertion element in the plastic housing is achieved, in particular, if this is made of plastic, whereby the insertion element compared to the metal parts is isolated.
- At least one side in the terminal housing below at least one of the openings Insertion bevel is provided so that the screwdriver when deriving on the Lead-in chamfer the actuator when switching in the direction of the contact blade presses and / or presses out of the contact blade when switching off.
- the insertion element formed in one piece with the terminal housing preferably enables inserting the conductor inserted into the terminal housing into the Contact cutting edge and / or the contact area.
- the insertion element facilitates in a simple manner the insertion of the conductor into the connection device. If it also made in one piece with the terminal housing (e.g. molded onto this) is, it can also be produced particularly inexpensively. The need for manufacturing a separate insertion element is not required.
- the at least one contact cutting edge is preferably immovable in the terminal housing fixed.
- the insertion element is attached to the Molded molded spring element.
- Spring element one or more pivotable in the terminal housing and to this molded spring bar (s) and a stop for the conductor, which is designed in this way is that by moving the spring element of the conductor at the stop directly in the Contact cutting edge and / or the contacting area is feasible.
- This variant too The invention realizes all the advantages of inexpensive production by injection molding the spring bar (or preferably two parallel spring bars).
- the field element enables a defined, easy mobility of the conductor in the contact cutting edge and can also be used multiple times.
- the spring element Due to the spring element - preferably the spring element has one in the terminal housing pivotable free spring bar with a bulge on which the stop trained for the leader - a leader becomes quasi “automatic” or alone Swiveling the spring bar led into the contact blades.
- the need for a further separate guide element which is separate from the terminal housing - As is known from various other prior art - omitted.
- the insertion element is in contrast as molded insert element molded onto the terminal housing, which via Predetermined breaking points is connected to the terminal housing in such a way that when moving the insertion element in the terminal housing with an operating tool Breakable points can be severed and the conductor can be inserted into the contact blade.
- This variant of the invention can also be produced inexpensively. It is suitable in essential for installation situations in which a multiple actuation of the connection device in all likelihood not necessary since the slider after switching on and off for re-wiring no longer with the terminal housing connected and thus held in its starting position for wiring is.
- the contact blades exist and the contacting areas - in particular as contacting areas designed - from different materials.
- This has the advantage that the material to cut open the insulation - this material should naturally be used the cutting function should be rather hard - as well as the material for contacting - it should good electrical conductivity - can be optimally selected according to your task.
- the conductor was cut open as well also the contacting by a one-piece element. This element is made of steel manufactured, a good cutting function of the insulation can be realized, the contacting but is significantly worse than in the case in which the contact surfaces or areas made of a softer conductive compared to the steel material Material such as copper.
- Fig. 1 shows a terminal block 2 - here a feed-through terminal - with a terminal housing 4 made of plastic, which has locking feet 6 in its lower area in FIG. 8 for snapping the terminal block 2 onto a mounting rail (not shown here) having.
- the terminal housing 4 is with two connection devices 10a, b for one each electrical conductor 12 provided, the conductors 12 each (see FIG. 1d) at least have a line core 14 and an insulation 16 surrounding the line core 14.
- connection devices 10 each comprise a contact blade 18 - preferably made of sheet steel - for cutting open the insulation 16 of the electrical conductor 12 and a contacting region 20a which is offset longitudinally relative to the contact cutting edge 18 - preferably made of copper - for contacting the at least one line core 14.
- the contact cutting edges 18 of the two connection devices 10a, 10b each sit on the ends of a through busbar 20.
- each connection device 10 is essentially vertical to the direction of insertion of the conductor 12 in the terminal housing 4 and is preferably slotted formed (see Fig. ld), the slot extending to the free end of the contact blade 18 mouth-like widened what the supply of the to be contacted Wire 12 relieved.
- the contact blade 18 made of sheet steel is used only to cut the Insulation 16 of the conductor 12. Slightly offset to the contact edge 18 sets the Busbar 20 on, which in its end region for the contacting area 20a trains the wire 20.
- the busbar 20 is parallel at its ends to the contact cutting edge 18 and is at its end facing the conductor 12 with Expansion bevels 22 provided which the insulation 16 of the conductor, previously from the contact blade 18 has been severed, expand laterally so that the in her End area slotted busbar 20 contact the line wire 14 laterally flat can.
- the busbar 20 has a substantially in the side view of FIG.
- the Contact blade 18 is made of sheet steel to make insulation 16 easy and safe to be able to penetrate, and the busbar 20 is used to ensure a good contact preferably made of copper.
- Two insertion elements 24 are used to insert the conductor 12 into the contact blades.
- these insertion elements 24 comprise two that are open at the top Recess 26 pivotable, mutually parallel spring bars 28, 30, which at their end facing away from the connection area to the rest of the terminal housing 4 are connected to one another via a stepped receptacle 32 Stop 34 for the lower end of the conductor 12 when it is inserted into the terminal housing 4 has.
- the insertion element 24 designed as a spring element can be at an angle of approximately Can be pivoted 20-40 ° in the terminal housing 4, the pivoting of the spring bars 28, 30 through a correspondingly large opening 36 on the top of the terminal housing 4 with the aid of a screwdriver 38. Through the Openings 36 also lead the conductors 12 into the terminal box 4 to the connection devices 10a, 10b out.
- the function of the connecting devices 10a, 10b of this terminal block 2 is like follows: In the relaxed state of the spring bars 28, 30, these lie to the conductor insertion direction slightly inclined. If a conductor 12 from above through the opening 36 in the Guided terminal housing 4, it abuts stop 34. Now becomes the screwdriver 38 on the outside of the conductor 12 and on the outside of the spring element 24 passed into the terminal block, it slides past the spring bars 28, 30. At the The screwdriver 38 slides down and swivels, pushing the insertion or Spring element 24 to the side and presses the lower region of the conductor 12 against the Contact cutting edge 18, where the insulation 16 of the conductor 12 is cut. Another one Swiveling the screwdriver 38 then forces the conductor 12 on the expansion bevels 22 past into the contacting areas 20a (left part of FIG. 1a and 1b).
- FIGS. 1a and 1b illustrates the opening of the connection devices 10a and 10b or the release of the conductor 12 from the connection device 10a, 10b.
- the screwdriver 38 on the (lying on the mounting rail) Passed inside the conductor 12 into the terminal housing 4 (see the left part of FIG. 2) until it rests on the busbar 20.
- the screwdriver 38 By swiveling and / or laterally shift the screwdriver 38 (see the right part of FIG Fig. 1a) to the outside it is possible to remove the conductor 12 from the connection area of the busbar 20 and to press out of the contact blade 18.
- the insertion element 24 is molded onto the terminal housing 4 Insert element formed, which has predetermined breaking points 40, 42 with the terminal housing 4 is connected such that when moving the insertion element in the Recess 26 perpendicular to the direction of the mounting rail in a plane parallel to the mounting rail the predetermined breaking points 40, 42 are severed with the screwdriver 38 and the conductor 12 is inserted into the contact blade.
- the loosening or de-switching takes place analogously to FIG. 1.
