Definitions

  • the present invention relates to an electrical connection socket, which is designed as a stamped and bent part, with one for receiving in a Chamber, in particular connector housing, trained housing part, on Housing part existing mechanical connection means for connection of the housing part with the chamber, one within the housing part arranged, electrically good conductive and especially elastic Connector receptacle and an electrically connected to the connector receptacle, also electrically well conductive cable connector for Connect to an exposed end of an electrical cable.
  • connection socket is known from EP 0 812 034 A1. She is punched out of a board and bent so that all components, in particular housing part with connector receptacle and cable connecting element can be formed from this board. The board is there thereby from electrically well conductive material to a low resistance to reach the connection socket.
  • the invention has for its object a connector Specify the type mentioned, which is a reduction in manufacturing costs enables without the mechanical and electrical properties of the connection socket.
  • connection socket consists of two assembled, separate stamped and bent parts is formed, of which the first the housing part with its mechanical connecting means and the second includes the connector receptacle and the cable connecting element.
  • connection book By forming the connection book from two separate stamped and bent parts, which are assembled for the finished connection socket, there is the advantage that different materials for the two parts can be used.
  • the materials can therefore be made accordingly the respective function of the stamped and bent part can be selected.
  • the mechanical and electrical properties of the Jack can be optimized, and secondly, the cost can be reduced be, because costly conductive material essentially only for the components that must actually be used for the power lines are needed.
  • connection socket can be produced from two stamped and bent parts, because fewer bends and fewer double walls are required than with the known connection socket mentioned above to all components the connection socket.
  • the plug receptacle of the connection socket according to the invention is preferred designed as a spring sleeve running parallel to the direction of insertion, wherein the spring sleeve also preferably two opposite, of which Inserted side to its middle led column, so two with Distance opposite spring legs are formed.
  • a such connector receptacle ensures a safe electrical contact while making and loosening the contact at the same time.
  • each spring leg by two parallel to the insertion direction Slits formed a spring tongue
  • the two spring tongues facing each other opposite and predetermined to form an insertion gap Size are bent towards each other.
  • Such Design allows both the Setting a desired gap dimension of the insertion gap as well a desired spring force. This can result in low insertion forces be achieved.
  • the gap size and the spring rate can be adjusted accordingly The punching and bending tool are adjusted.

  • the molded-in insertion tabs can be used to insert a plug be relieved. This can also prevent incorrect insertion be that the insertion tabs the gap between the connector receptacle and cover the housing part.
  • the housing part For engaging an inward projection, for example Locking arm, an associated receiving chamber, the housing part in in a manner known per se prefers window-like lateral recesses on.
  • the housing part is on the with the projection against pulling out of the housing part cooperating from the receiving chamber Edge of the window with an inwardly bent tab provided that serves as a stop for the projection. Through the tab the stop surface is advantageously increased. The power distributed thereby better on the projection, causing damage to the Advantage when trying to pull out the connector can be avoided from the receiving chamber.
  • the tab attaches to the housing part has in its central area a recess in which the Wall of the housing part is not bent, but a straight edge forms, which is approximately aligned with the engagement surface of the tab. Through this Edge can advantageously cause the projection to slide out Exerting a pulling force on the connection socket can be prevented.
  • This configuration can also be used with other generic connection sockets be used.
  • connection socket according to the invention also in connection with reception chambers, in particular Connector housings are used next to a main locking element also use an additional locking element.
  • the stop edge is as large as possible Has height, in particular by the transition area between the connector receptacle and cable connecting element formed with a low height is.
  • the connection socket according to the invention can thereby still more different admission chambers work together so that their Possible uses are further enlarged.
  • the housing part faces on its side facing away from the insertion side according to a further embodiment of the invention also two on opposite Lugs formed on the long sides for guiding the connector receptacle during assembly and subsequent radial Support on.
  • the joining of the two stamped and bent parts at the Manufacture of the connection socket according to the invention can thereby be relieved.
  • the connector holder is inside of the housing part positioned in the desired position.
  • the attachment of the tab preferably runs parallel to the direction of insertion, and the distance of the tabs from one another tapers in the direction of the insertion side of the housing part. On the one hand, this can be sufficient Holding force guaranteed and on the other hand an insertion of the connector receptacle in the housing part during assembly.
  • stamped bent part formed butt edge of the connector holder on the side of the middle tabs and the abutting edge of the housing part on the opposite Side is arranged.
  • the holding force of the housing part on the The connector is particularly large because the tabs on the Attack the side of the butt edge of the connector receptacle and the housing part can not diverge on this page.
  • the connector receptacle at least one recess into which a projection of the housing part intervenes to axially block both.
  • the Plug receptacle can also axially within the housing part be fixed.
  • Two inwardly bent tabs are preferred on the housing part provided, in particular in a common recess in the Intervene in the connector receptacle.
  • the tabs can be assembled of the connector receptacle and housing part are bent inwards and ensure good blocking.
  • the attachment of the tabs preferably extends parallel to the direction of insertion, and the width of the tabs tapers towards their free end conical. This configuration facilitates a firm axial blocking of the Part of the housing opposite the connector receptacle.
  • the connection socket according to the invention comprises a first stamped and bent part 1, which is shown in Fig. 2, and a second stamped and bent part 2, which is shown in Fig. 4 by itself.
