Definitions

  • the invention relates to a conductor connection terminal with a sheet metal part and with at least one clamping spring that protrudes from the sheet metal part and is connected to the sheet metal part in a root area of the sheet metal part.
  • Such conductor connection terminals are known, for example, in the form of box terminals, in which several electrical conductors are connected to one another in an electrically conductive manner using a common contact element.
  • EP 1 855 353 B1 describes such a conductor connection terminal with a spring steel sheet and a busbar suspended in this spring steel sheet.
  • the terminal points for connecting an electrical conductor are each formed between the free ends of leaf spring tongues and the busbar.
  • the leaf spring tongues are cut free from the spring steel sheet in such a way that their tongue roots are firmly connected to the upper edge area of the spring steel sheet.
  • the bus bar is inserted into a V-shaped accommodating space.
  • the lengths of the leaf spring tongues are dimensioned in such a way that, when the clamping point is closed and unoccupied, their tongue ends reach through the window recess of the spring steel sheet and lie against the underside of the conductor rail.
  • DE 40 03 701 A1 shows a device connection terminal with a contact insert plate, which is bent over in a V-shape to form a elbow joint towards the terminal leg section. This results in a shaped surface of the contact insert sheet, which directly represents a side half of a socket part of a plug connection that is integrated into the device connection terminal.
  • DE 196 54 523 A1 discloses a conductor terminal which is formed from a busbar bar and a spring steel sheet, from which leaf springs are punched in the form of tongues, the tongue ends of which are punched free and are directed towards the busbar bar.
  • U.S. 9,105,991 B1 shows an electrical contact element with a two-part housing, with a connecting element between the housing parts forming a clamping area for an electrical conductor.
  • DE 10 2006 010309 A1 discloses a socket terminal, the socket terminal having two opposed contact members which are electrically connected to each other via a separate insert.
  • the socket terminal has conductor entry channels that act as release buttons for an electrical conductor.
  • DE 203 03 537 U1 discloses a box terminal for connecting a plurality of electrical conductors.
  • a plurality of adjacent tongues are cut free from a carrier element, which together with a contact element form clamping points for electrical conductors to be clamped on.
  • the contact tongues merge into the carrier element in a straight line.
  • CN 202 888 493 U shows a three-part electrical connector, a clamping spring projecting from each part in order to form a clamping point for an electrical conductor to be clamped.
  • US 4,397,514A discloses a conductor connection terminal with a self-retaining contact element, which is formed from a U-shaped busbar and a clamping spring connected to the busbar via a strap connection.
  • the clamping spring is designed as a folded leaf spring with a spring loop.
  • U.S. 7,150,646 B2 discloses a conductor terminal with a contact element consisting of a leaf spring section and a carrier section which are welded together.
  • the carrier section is latched in the surrounding insulating housing and has a groove-shaped receptacle for a busbar rod.
  • the sheet metal part is curved in the root area.
  • the bulge has a groove base of a groove of the bulge oriented transversely to the main extension direction of the clamping spring.
  • This bulge is not only present in the area of the tongue root of the clamping spring tongue, but is also found in the adjacent part of the sheet metal part, which merges into the side webs delimiting the opening.
  • this curvature improves the spring elasticity of the clamping spring after it has been punched out.
  • the clamping spring is first bent back against the spring force of the clamping spring in the bulge and then elastically deformed. In this way, the length of the clamping spring can be shortened or a very low-profile conductor connection terminal can be implemented.
  • the bulge in particular when a multi-wire conductor is inserted, means that this occurs on the elastic part of the clamping spring, so that the clamping spring is already elastically deformed when the electrical conductor is inserted.
  • the central extension of the clamping spring from the root area of the clamping spring to the clamping end of the clamping spring is to be regarded as the main direction of extension of the clamping spring.
  • the main extension direction of the clamping spring can be defined by the area of the clamping spring lying in the conductor insertion channel between the root area and the bearing section of the sheet metal part.
  • the main extension direction of the clamping spring is defined exclusively by the region of the clamping spring delimited in the conductor insertion channel by the side web and the bearing section of the sheet metal part.
  • the sheet metal part is provided with two bulges in the root area. These two bulges can adjoin one another and be designed in opposite directions to one another, that is to say in an S-shape. This increases the elastic effect of the clamping spring. Following the first bulge, the second bulge can follow essentially in the direction of the clamping end of the clamping spring. In the direction of main extension of the clamping spring, this S-shaped design results in a kind of parallelism of the course of the clamping spring to the transverse web or to the surface of the transverse web that faces the conductor entry.
  • the course of the main extension direction of the clamping spring is essentially in the conductor insertion channel, ie in the area between the support section and the side bar or the root area of the clamping spring.
  • the first curvature and the second curvature can thus be designed in such a way that the main extension direction of the clamping spring in the non-deflected state of the clamping spring is parallel, i.e. approximately parallel +-10°, to the surface of a transverse web of the sheet metal part adjoining the root area or to the transverse alignment of the transverse web is aligned transversely to the direction of longitudinal extension of the transverse web or the direction in which the clamping springs are arranged.
  • the conductor connection terminal can have an insulating material housing and a contact element, the contact element having the sheet metal part with the at least one clamping spring arranged thereon.
  • the insulating housing has at least one conductor entry channel leading to a respective clamping spring. There is an opening in the sheet metal part for receiving a conductor entry channel in an associated one imported electrical conductor available.
  • the insulating material housing can have channel side walls that delimit the conductor insertion channel and extend into the opening.
  • channel side walls now protrude into the opening in the sheet metal part facilitates improved guidance, in particular of multi-wire conductors, through the opening.
  • the strands are held together with the help of these channel side walls beyond the terminal point.
  • the strands are prevented from moving out, for example due to the application of force by the clamping spring, or at least the risk of moving out is reduced, in that the channel side walls provide lateral guidance of the electrical conductor to be connected in the direction of conductor insertion beyond the clamping point.
  • the sheet metal part can be bent in the area of the opening.
  • the channel side walls then dip through the opening in the bent section of the sheet metal part. This enables a very compact embodiment of the conductor connection terminal with good conductor routing.
  • each conductor entry channel there can be two channel side walls spaced apart from one another, which are arranged at a distance from one another and dip into the opening. This enables the conductor to be routed on both sides.
  • the channel side walls may be T-shaped in cross-section, particularly for the outer channel side walls, or H-shaped in cross-section, i.e. double T-shaped.
  • These duct side walls, which have an H-shaped cross section, can be provided in particular for the conductor entry ducts lying next to one another.
  • These T- and H-shaped cross sections increase the stability of the channel side walls with a compact design.
  • the groove of the first bulge can be located on the side of the sheet metal part that is opposite the side of the sheet metal part from which the clamping spring protrudes.
  • the at least one clamping spring is formed in one piece from the material of the sheet metal part.
  • the clamping spring is exposed from the sheet metal part (e.g. cut or punched free) and bent out of the plane of the sheet metal part. There is a hole in the plane of the sheet metal part. This opening is the window that remains after the clamping spring has been uncovered from the sheet metal part and is delimited by two side bars.
  • the sheet metal part can carry an electrically conductive busbar opposite the free end of the clamping spring.
  • the provision of such a separate conductor rail, on which the electrical conductor rests and is clamped by the spring force of the clamping spring, has the advantage that improved current transfer can be ensured by selecting a different, electrically conductive material, e.g. with a higher copper content.
  • the clamping point can also be formed between the clamping spring and a web of the sheet metal part lying opposite the clamping spring.
  • the conductor connection terminal can have an insulating material housing with a housing part in which the sheet metal part is accommodated.
  • the housing part is then closed with a cover part, which can be latched to the housing part, for example.
  • the cover part then has at least one conductor entry channel leading to the one of the respective clamping springs.
  • the channel side walls are formed on a cover part.
  • FIG. 1 shows a side sectional view of a first, single-row conductor terminal 1 for clamping electrical conductors.
  • the conductor terminal 1 has an insulating material housing 2 which is formed from a housing part 3 and a cover part 4 which closes the housing part 3 at the front.
  • the cover part 4 is pushed into the housing part 3 and locked with it.
  • a contact element 5 is inserted, which has a sheet metal part 6 and a busbar 7 .
  • the sheet metal part 6 has a clamping spring 8 which is exposed from the sheet metal part 6 (eg cut or punched free) and is bent out of the plane of the sheet metal part 6 .
  • the bending out of the clamping spring 8 leaves an opening in the sheet metal part 6 limited by side webs 9.
  • the freely movable end of the clamping spring 8 forms a clamping end which, for example, rests on the busbar 7 in the unoccupied state of rest and together with the busbar 7 forms a clamping point for clamping forms an electrical conductor clamped between the terminal end 10 and the busbar 7 .
  • the sheet metal part is bent in a U-shape and has a support section 11 for the conductor rail 7 adjacent to the terminal end 10 .
  • the cover part 4 has a conductor entry channel 12 which is delimited by the side walls 13 of the channel.
  • the channel side walls 13 of the cover part 4 extend laterally past the clamping spring 8 into the opening in the sheet metal part 6 .
  • the channel side walls 13 can protrude behind the sheet metal part 6 in the direction of conductor insertion L and protrude into a conductor collecting pocket 14 . However, they can also end at the side webs 9 of the sheet metal part 6 . This provides lateral guidance of an electrical conductor to be clamped beyond the clamping point.
  • the clamping spring 8 is centered and guided laterally.
  • the figure 2 omits conductor terminal 1 figure 1 now see with inserted and clamped electrical conductors 15.
  • This electrical conductor 15 has an insulating material jacket 16 which surrounds the electrically conductive conductor core 17 .

  • the stripped end of the electrical conductor 15 rests on the side of the conductor rail 7 which is diametrically opposite the clamping edge 10 .
  • the electrical conductor 15 is pressed against the busbar 7 by the spring force of the clamping spring 8 and the electrical conductor 15 is prevented from being pulled out by the sharp-edged clamping edge 10 of the clamping spring 8 .
  • clamping spring 8 is convexly curved in the root area 18, i.e. in the transition to the frame-like sheet metal part 6 in this clamping position of the conductor rail 7.
  • the root area 18 with this arched section contributes significantly to the spring elasticity and to the application of the necessary spring force.
  • the sheet metal part 6 is folded opposite to the root area 18 with two spaced bends so that the side bars 9, which limit the opening, extend transversely (90 degrees +/-10 degrees) to the longitudinal direction of the clamped electrical conductor 15.
  • the clamping end 10 of the clamping spring 8 moves out of the rest position ( figure 1 ) to clamp position ( figure 2 ) seen in conductor insertion direction L in front of this transverse section of the side bars 9.
  • clamping spring 8 extends in a main extension direction H, which is defined by the central alignment of the clamping spring 8 in the conductor insertion channel 12 in the area of the clamping spring 8 delimited by the side web 9 and the bearing section 11 of the sheet metal part 6.
