Definitions

  • the invention relates to a flat contact socket with a connecting portion for electrical connection to at least one electrical conductor and with a flat in a socket body along a flat contact plane extending flat contact receptacle, in 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 with a flat contact.
  • Flat contact sockets with which an electrical connection between at least one electrical conductor and a flat contact can be made, are known.
  • a disadvantage of the known flat contact sockets is that they usually only unevenly distribute a current flow of at least one conductor to a flat contact received in the flat contact receptacle, as a result of which heavily flowed regions are formed in which temperature increases caused by the electrical resistance lead to damage of the component can.
  • connection arrangement according to the invention the object is achieved by a flat contact socket according to the invention, whose connection surface is electrically conductively connected to at least one electrical conductor.
  • the solution according to the invention makes it possible to guide the flow of current through the flat contact socket over the at least two extensions and thereby distribute them. This can avoid that individual areas are heated so much by the flow of current that it comes to damage.
  • currents of more than 200 amperes can be conducted through the flat contact socket. Characterized in that the at least two areas from which extend the extensions are spaced from each other, the current can also be directed to different locations of the flat contact socket or the female body, so that a better distribution of the current flow is achieved to a arranged in the FlachCountability flat contact ,
  • connection section may extend in such a way that an electrical conductor extends in a connected state, at least in the region of the connection section, transversely to a plug-in direction of a flat contact into the flat contact receptacle.
  • connection section may extend in such a way that an electrical conductor extends at least in the region of the connection section parallel to the insertion direction.
  • the flat contact socket of the connecting portion is preferably spaced from the flat contact receptacle, but connected thereto.
  • At least one of the extensions can be monolithically formed with the socket body to achieve a simple structure and a good electrical conductivity.
  • connection surface can be used in particular for connection to at least one electrical conductor by welding or soldering.
  • connection surface is preferably straight and flat and accessible for a tool.
  • the socket body may have at least two opposite to the flat contact plane leg through which the flat contact receptacle is limited transversely to the flat contact plane.
  • the two legs can be aligned substantially flat and parallel to the flat contact plane.
  • At least one, in particular monolithic, extension of each of the legs can extend with this formed extension.
  • each of the two legs can be connected via the respective extension with an electrical conductor.
  • 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 portion is first to one of the two legs and then from this leg to the other leg.
  • At least one extension of its associated leg can extend straight and continuously into the connecting portion.
  • the leg and the extension connected with this or monolithic extension 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 so that it initially extends substantially 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 Forming connecting surface, which, viewed transversely to the flat contact plane, is arranged at the level of the inside of one of the legs.
  • the at least two extensions each of which extends at least one of one of the two legs away, initially extend in the direction of the opposite leg and then in the connecting portion.
  • the height of the connecting surface can then, viewed transversely to the flat contact plane, be arranged between the two opposing legs.
  • the extensions may extend along a plane which is located centrally between the two legs.
  • At least one of the legs may have at least one contacting section for making electrical contact with the flat contact on one leg inside.
  • the inside is the side which is assigned to the flat contact receptacle, or which limits the flat contact receptacle.
  • both legs each have a contacting portion, which lie opposite each other 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, both contacting sections can be connected via at least one extension to at least one electrical conductor, whereby a current flow can take place directly from the connection 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 has a plurality of such contact springs.
  • the at least one contact spring does not have to be formed integrally 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 may be formed of a material which has been selected for good electrical conductivity.
  • the at least one contacting plate is preferably bonded to the inside of at least one leg, in particular by welding.
  • each of the at least two legs is provided with at least one contacting plate, which lie opposite each other transversely to the flat contact receptacle.
  • a particularly compact embodiment of the flat contact bush according to the invention can be obtained by arranging the two extensions in the connecting section lying against one another and forming a connecting surface running parallel to the flat contact plane.
  • the two extensions can be arranged adjacent to each other.
  • the common connecting surface formed by the at least two extensions need not necessarily be formed continuously. 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 a current flow through both extensions is made possible.
  • connection surface may 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 if electrical conductors, such as cables, are to be used, whose cross-section 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 with more than one electrical conductor, preferably one of the extensions is connected to one of the electrical conductors.
  • each of the extensions can be welded to one electrical conductor, in particular one cable.
  • the at least two legs can be connected via at least one, the insertion in the insertion opposite, web.
  • the distance between the at least two legs can be fixed to one another.
  • the flat contact socket may have at least one form-locking recess extending substantially parallel or transversely to the insertion direction into the flat contact bushing for producing a positive connection with a housing.
  • the at least one form-fitting recess can in particular be arranged between the connection section and the socket body.
  • the at least one form-fitting recess may preferably extend parallel to the insertion direction of a flat contact into the flat contact socket.
  • the at least one form-fitting recess preferably extends transversely to the insertion direction into the flat contact socket.
  • At least one stop face extending parallel or transversely to the plug-in direction can be formed on the socket body in a housing for securing the flat contact socket.
  • a housing for example an insulating housing for receiving the flat contact socket, may have a form-locking element which is received in the form-fitting recess in an assembled state in which the flat contact socket is accommodated in the housing.
  • the housing may be formed so that the positive-locking element abuts against another part of the flat contact socket, when trying to insert the flat contact socket in a different orientation in the housing, as that in which the positive-locking element is received in the form-fitting.
  • the interaction of the form-fitting element with the form-fitting recess thus constitutes an element for avoiding errors during assembly.
  • the positive-locking element can abut against the stop surface, so that a detachment of the flat contact socket from the housing, in particular in the direction of the connecting portion is effectively prevented. This is especially true in the case that a tensile force is exerted on an electrical conductor connected to the connecting portion.
  • this can be made in particular as a stamped and bent part.
  • 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, in particular formed by stamped bending, monolithically formed with the socket body lateral guide elements, which can lead a flat contact transversely to the insertion.
  • the guide elements can in particular be arranged so that they can at least partially close off two legs on a side arranged transversely to the insertion opening.
  • the flat contact socket may be provided with at least one notch, which is designed for the positive reception of at least one complementary formed position securing element of the housing.

  • the region 97b is the end of the leg which is in the direction of the connection section 3 21 b.
  • Each of the extensions 95 thus extends away from one of the legs 21.
  • the extension 95 a extends continuously from the leg 21 a parallel to the flat contact plane 11 and forms with the leg 21 a is a continuous and substantially flat surface.
  • the extensions 95a and 95b may both initially in the direction of the respective opposite leg 21 b relationship meadow 21 a and then extend into the connecting portion 3.
  • the height of the connecting surface 93 can then, viewed transversely to the flat contact plane 11, be arranged between the two opposing legs 21a and 21b.
  • the extensions 95a and 95b may extend along a plane which lies centrally between the two legs 21a and 21b.
  • the extension 95b is shaped starting from the leg 21b such that it first extends away from the socket body 7 in the direction of the leg 21a and then along the longitudinal direction 19. This allows both extensions 95 in the region of the connection surface 93 be arranged at a height.
  • the term height here 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 so that it is arranged starting from the leg 21b at a height with the extension 95a.
  • the offset region 99 is seen in the insertion direction 17 S-shaped.
  • the extension 95b extends from the leg 21b initially in the longitudinal direction 19 away from the leg 21b and then extends at least partially in the direction of the leg 21a and the socket body 7. Subsequently, the extension 95b extends away from the socket body 7 in the longitudinal direction 19th As a result, a region 101 curved toward the socket body 7 is formed, whose convex side 103 points towards the socket body 7 and whose concave side 105 is open in the direction of the connection section 3. Through the concave side 105, a connecting surface 93 extended in the longitudinal direction 19 can be obtained.
  • An electrical conductor 107 (can be welded to the connection surface 93 in the connection section 3, so that a connection is made to both extensions 95. A current flow through the flat contact socket 1 can then be split over both extensions 95 onto the two legs 21.
  • each of the extensions 95a and 95b can also be welded to at least one electrical conductor. This is in Fig. 2 exemplified.
  • 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 low-profile conductors are generally more flexible than a single conductor having a cross-section corresponding to the overall cross-section of the two individual conductors, smaller bending radii can be realized in laying the conductors 107.
  • the flat contact socket 1 in conjunction with at least one electrical conductor 107 represents a connection arrangement 109 according to the invention.
