Definitions

  • the invention relates to a flat contact socket with a connecting section for electrical connection to at least one electrical conductor and with a flat contact receptacle extending in a socket body along a flat contact plane, into which a flat contact can be inserted.
  • the invention also relates to a connection arrangement for the electrical connection of at least one electrical conductor to a flat contact.
  • Flat contact sockets with which an electrical connection can be made between at least one electrical conductor and a flat contact are known.
  • a disadvantage of the known flat contact sockets is that they generally only distribute a current flow from at least one conductor to a flat contact received in the flat contact receptacle unevenly, as a result of which areas with high flow rates arise in which temperature increases caused by the electrical resistance lead to damage to the component can.
  • the solution according to the invention allows the current flow through the flat contact socket to be conducted over the at least two extensions and thereby distributed. In this way it can be avoided that individual areas are heated to such an extent by the current flow that damage occurs.
  • currents of more than 200 amperes can be conducted through the flat contact socket. Because the at least two areas that make up If the extensions extend and are spaced apart from one another, the current can also be conducted to different locations of the flat contact socket or the socket body, so that a better distribution of the current flow to a flat contact arranged in the flat contact receptacle is achieved.
  • the solution according to the invention can be used both for angled connections (90 ° connections) or for straight connections (180 ° connections).
  • the connecting section can extend in such a way that an electrical conductor in a connected state extends at least in the region of the connecting section transversely to a direction of insertion of a flat contact into the flat contact receptacle.
  • the connection section can extend such that an electrical conductor runs parallel to the insertion direction, at least in the region of the connection section.
  • the connecting section is preferably spaced from the flat contact receptacle, but is connected to it.
  • At least one of the extensions can be formed monolithically with the socket body in order to achieve a simple structure and good electrical conductivity.
  • connection surface can be used in particular for connection to at least one electrical conductor by welding or soldering.
  • the connecting surface is preferably straight and level and accessible for a tool.
  • the socket body can have at least two legs lying opposite one another transversely to the flat contact plane, by means of which the flat contact reception is limited transversely to the flat contact plane.
  • the two legs can in particular be aligned essentially flat and parallel to the flat contact plane.
  • At least one, in particular monolithic, extension formed with this can extend away from each of the legs.
  • each of the two legs can be connected to an electrical conductor via the respective extension.
  • a flat contact received in the flat contact receptacle can be electrically contacted via both legs. This is advantageous since the current flow through the flat contact socket can be increased in comparison to an embodiment in which the current flow from the connecting section first to one of the two legs and then from this leg to the other leg.
  • At least one extension can extend straight and continuously from its associated leg into the connecting section.
  • the leg and the extension connected to it or formed monolithically can extend parallel to the flat contact plane.
  • At least one further extension, which is formed or connected to the opposite leg can then be shaped such that it initially extends essentially transversely to the flat contact plane in the direction of the opposite leg and then into the connecting section, so that the at least two extensions one Form connecting surface, which, seen transversely to the flat contact plane, is arranged at the level of the inside of one of the legs.
  • the at least two extensions at least one of which extends from one of the two legs, can initially extend in the direction of the opposite leg and then into the connecting section.
  • the height of the connecting surface can then, seen transversely to the flat contact plane, be arranged between the two opposite legs.
  • the extensions can extend along a plane that lies centrally between the two legs.
  • At least one of the legs can have at least one contacting section on the inside of the leg for electrically contacting the flat contact.
  • the inside is the side that is assigned to the flat contact or that limits the flat contact.
  • Both legs preferably have a contacting section, which lie opposite one another transversely to the flat contact plane. If at least one extension extends from each of the legs, each of the contacting sections can be connected to the connecting surface via the associated extension. As a result, the two contacting sections can each be connected to at least one electrical conductor via an extension, as a result of which a current can flow directly from the connecting section to the contacting sections.
  • the at least one contacting section can be provided with at least one contact spring which projects into the flat contact receptacle and can be deflected elastically to the leg.
  • the at least one contacting section preferably has a plurality of such contact springs.
  • the at least one contact spring does not have to be formed in one piece with the leg.
  • the at least one contacting section can be provided with a contacting plate be, which has a plurality of contact springs.
  • the contacting plate can be formed from a material which has been selected for good electrical conductivity.
  • the at least one contacting plate is preferably integrally connected to the inside of at least one leg, in particular by welding.
  • Each of the at least two legs is preferably provided with at least one contacting plate, which lie opposite one another transversely to the flat contact.
  • a particularly compact embodiment of the flat contact socket according to the invention can be obtained in that the two extensions are arranged adjacent to one another in the connecting section and form a connecting surface running parallel to the flat contact plane.
  • the two extensions can be arranged adjacent to one another.
  • the common connecting surface formed by the at least two extensions does not necessarily have to be continuous. It is also possible, for example, that a gap caused by the production is present between the two extensions. At least one electrical conductor can then be connected to both extensions, in particular by welding, so that current can flow through both extensions.
  • connection surface can be connectable to more than one electrical conductor.
  • each of the at least two extensions can be connected to at least one electrical conductor. This is particularly advantageous when electrical conductors, for example cables, are to be used, the cross-section of which is smaller than that of a cable when connected to only one electrical conductor. This configuration can be selected, for example, if smaller bending radii are required for the cables.
  • one of the extensions When connecting to more than one electrical conductor, one of the extensions is preferably connected to one of the electrical conductors.
  • each of the extensions can be welded to an electrical conductor, in particular a cable.
  • the at least two legs can be connected via at least one web opposite the insertion opening in the insertion direction.
  • the distance between the at least two legs can thereby be fixed.
  • the flat contact socket can have at least one form-fit recess which extends essentially parallel or transversely to the direction of insertion into the flat contact socket for producing a form-fit connection with a housing.
  • the at least one form-fitting recess can in particular be arranged between the connecting section and the socket body.
  • the at least one form-fit recess can preferably extend parallel to the direction in which a flat contact is inserted into the flat contact socket.
  • the at least one form-fit recess preferably extends transversely to the direction of insertion into the flat contact socket.
  • the at least one form-fitting recess can be used to form at least one stop face in the housing body parallel to or transversely to the direction of insertion for securing the flat contact socket in a housing.
  • a housing for example an insulation housing for receiving the flat contact socket
  • the housing can be formed in such a way that the form-locking element abuts another part of the flat contact socket when an attempt is made to insert the flat contact socket into the housing in a different orientation than that in which the form-fitting element is received in the form-fitting recess.
  • the interplay of the form-fitting element with the form-fitting recess thus represents an element for avoiding errors when assembling.
  • the form-fitting element can abut against the stop surface, so that detachment of the flat contact socket from the housing, in particular in the direction of the connecting section, is effectively prevented. This applies in particular in the event that a tensile force is exerted on an electrical conductor connected to the connecting section.
  • the flat contact socket can have at least one locking element which connects or locks the leg ends pointing against the insertion direction.
  • the flat contact socket according to the invention can have lateral guide elements, in particular formed by stamping bending and formed monolithically with the socket body, which can lead a flat contact transverse to the direction of insertion.
  • the guide elements can in particular be arranged such that these two legs can at least partially close on a side arranged transversely to the insertion opening.
  • the flat contact socket can be provided with at least one notch, which is designed for the form-fitting reception of at least one complementary position securing element of the housing.
  • the flat contact socket 1 has a connecting section 3 for the electrical connection to an electrical conductor.
  • a socket body 7 is connected to the connecting section 3.
  • the socket body 7 essentially serves for connection to a flat contact 63 (in Fig. 2 indicated).
  • the socket body 7 has a flat contact receptacle 9.
  • the flat contact receptacle 9 extends along a flat contact plane 11, which in Fig. 1 is indicated by dashed lines.
  • the flat contact receptacle 9 is opened for inserting a flat contact through an insertion opening 13.
  • a locking element 15 which limits the depth of penetration for a flat contact 63 into the flat contact receptacle 9.
  • the insertion direction 17 extends from the insertion opening 13 in the direction of the locking element 15.
  • the insertion direction 17 runs parallel to the flat contact plane 11.
  • the insertion opening 13 and the locking element 15 therefore lie opposite one another in the insertion direction 17.
  • the flat contact socket 1 extends along a longitudinal direction 19 running transversely to the insertion direction 17.
  • the connecting section 3 and the socket body 7 are adjacent in the longitudinal direction 19.
  • the connecting section 3 is designed such that an electrical conductor, in particular a cable, after the connection to the connecting section 3 likewise initially runs essentially parallel to the longitudinal direction 19 in the area directly adjacent to the flat contact socket 1.
  • the flat contact socket 1 can also be shaped differently.
  • the connecting section 3 can be connected to the socket body 7 in such a way that the connecting section 3 extends parallel to the insertion direction 17 away from the latter.

  • the socket body 7 has two flat legs 21a and 21b opposite one another transversely to the flat contact plane 11. If the properties of an individual leg 21a and 21b are not important, the embodiment is described below for the sake of clarity with reference to the leg 21.
  • the legs 21 delimit the flat contact receptacle 9 transversely to the flat contact plane 11.
  • the legs 21 are preferably formed essentially continuously. Alternatively, they can also have openings, for example to save material.
  • the two legs 21 are connected to one another by two webs 25.
  • the flat contact socket 1 is preferably made as a stamped and bent part made of an electrically conductive material 28. The production by stamping bending enables the flat contact socket 1 to be manufactured quickly and inexpensively.

  • the locking element 15 projects from the extension arm 31 transversely to the insertion direction 17 and transversely to the longitudinal direction 19, that is to say transversely to the flat contact plane 11.
  • the arrangement of the locking element 15 on the extension 31 extending in the insertion direction 17 makes it possible to accommodate a flat contact 63 in the flat contact receptacle 9, which at least partially projects beyond the remaining socket body 7 in the insertion direction 17. In this way, a flat contact 63 can be accommodated, which comprises additional elements, for example a protection against accidental contact.
  • the locking element 15 is spaced apart from the rest of the flat contact receptacle 9 by the arrangement described above.
  • the locking element 15 is preferably made in one piece with the socket body 7 and particularly preferably with the rest of the flat contact socket 1. This can be achieved in particular in that the flat contact socket 1 is formed as a stamped and bent part.
  • the locking element 15 and the extension arm 31 can be punched out of the material 28 of the flat contact socket 1, which would form a continuous base in the region of the socket body 7 without a locking element 15 according to the invention. It can continuously merge into the leg 21b and the free end, which forms the blocking element 15, can be bent up transversely to the insertion direction and transversely to the longitudinal direction 19.
  • the locking element 15 has two struts 33, via which it is connected to the boom 31.

  • the locking elements 41 limit the insertion opening 13 laterally or in the longitudinal direction 19.
  • Each of the locking elements 41 extends from the leg 21b to the opposite leg 21a, although it can also be reversed in an alternative embodiment.
  • Each of the locking elements 41 has a form-fitting opening 43. This is preferably arranged at the free end 45 of the locking element 41.

  • the two extensions 95a and 95b extend from two spaced apart regions 97a and 97b of the socket body 7.
  • the region 97a is the end of the leg 21a in the direction of the connecting section 3 and the region 97b is the end of the leg in the direction of the connecting section 3 21b.
  • Each of the extensions 95 thus extends away from one of the legs 21.
  • the extension 95a extends continuously from the leg 21a parallel to the flat contact plane 11 and forms a continuous and essentially flat surface with the leg 21a.
  • the extensions 95a and 95b can both initially extend in the direction of the respectively opposite leg 21b or 21a and then into the connecting section 3.
  • the height of the connecting surface 93 can then, seen transversely to the flat contact plane 11, be arranged between the two opposite legs 21a and 21b.
  • the extensions 95a and 95b can extend along a plane which lies centrally between the two legs 21a and 21b.
  • the extension 95b is shaped starting from the leg 21b in such a way that it first extends in the direction of the leg 21a and then along the longitudinal direction 19 away from the socket body 7. This allows both extensions 95 in the area of the connecting surface 93 be arranged at one level.
  • the term height refers to a direction transverse to the insertion direction 17 and longitudinal direction 19 or parallel to the direction of the height 35 of the flat contact receptacle 9.
  • the extension 95b has the offset region 99, in which the extension 95b is shaped such that it is arranged starting from the leg 21b at a level with the extension 95a.
  • the offset region 99 is S-shaped when viewed in the insertion direction 17.
  • the extension 95b initially extends in the longitudinal direction 19 from the leg 21b away from the leg 21b and then runs at least in sections in the direction of the leg 21a and to the socket body 7. Then the extension 95b again extends away from the socket body 7 in the longitudinal direction 19.
  • a region 101 is formed which is curved toward the socket body 7, the convex side 103 of which points towards the socket body 7 and the concave side 105 of which is open in the direction of the connecting section 3.
  • a concave side 105 makes it possible to obtain a connecting surface 93 which is extended in the longitudinal direction 19.
  • An electrical conductor 107 (can be welded in the connecting section 3 to the connecting surface 93, so that a connection to both extensions 95 is established. A current flow through the flat contact socket 1 can then be divided between the two legs 21 via both extensions 95.
  • each of the extensions 95a and 95b can also be welded to at least one electrical conductor.
  • the advantage of using at least two electrical conductors 107 is that both conductors 107 can each have a smaller line cross section than would be the case with a single conductor. Since the two conductors with a small cross section are generally more flexible than a single conductor with a cross section that corresponds to the overall cross section of the two individual conductors, smaller bending radii can be achieved when the conductors 107 are laid.
  • the flat contact socket 1 in connection with at least one electrical conductor 107 represents a connection arrangement 109 according to the invention.
