Definitions

  • the invention relates to an electrical receptacle contact for high-current applications, comprising a trained in the manner of a cage connector receptacle for receiving a complementary male contact with two opposite each other with respect to the connector receptacle side parts and comprising a disposed within the connector receptacle contact blade insert with at least one parallel to a side member extending body and with a plurality, with their contact areas from the plane of the body protruding, connected to the main body contact blades.
  • Such an electrical socket contact is off US Pat. No. 6,692,316 B2 known.
  • Such socket contacts are used to form a connector, for example in motor vehicles. Electrical connectors for high current applications are designed to be larger than those required for low power or electronic applications.
  • the socket contact for high current applications known from the aforementioned document comprises a plug receptacle which is designed in the manner of a cage. This cage is designed in cross-section U-shaped. In this U-shaped receptacle a contact blade insert is inserted and conductively connected to the cage, for example, welded.
  • the contact blade insert is in turn designed U-shaped and comprises two spaced-apart base body, each having a plurality of contact blades. The contact blades emerge with their contact areas from the plane of the body. Between the contact blades is the actual receptacle for receiving a plug contact complementary to the socket contact, which is designed as a blade contact. Due to the U-shaped design of the contact blade insert this is sometimes referred to as a lamellar basket.
  • the lamellar basket has contact louvers exposed by punching, which extend from the upper edge of the respective base body to the lower edge.
  • the main body thus forms a frame for the contact blades, which are connected on both sides of this.
  • the contact blades themselves are embossed to form contact areas, which issued from the plane of the body to be used for contact are. For the exhibition of the contact blades, these are bent by the axes of their longitudinal extension in the region of their central portion by a few degrees.
  • the complementary blade contact can be inserted parallel to the orientation of the contact blades and thus from above or from that side to which the inclined contact blade side has.
  • the contact blade insert can be used in the connector receptacle in two different orientations so that the electrical receptacle contact can be contacted depending on the intended use of the contact blade insert from above and from the right or from the top and the left side.
  • An advantage of this socket contact is that with one and the same elements of the socket contact can be contacted from different directions contacted.
  • the U-shaped connector receptacle has a cutout provided in the region of the U-shaped fold which serves to engage a latch or pin assigned to a housing for receiving the receptacle contact for locking the receptacle contact inserted in the housing.
  • the invention is therefore the object of developing an aforementioned electrical socket contact such that it is always contacted from different directions regardless of the installation of devislamellentives the socket contact.
  • the contact blades are connected only on one side of their body.
  • the contact blades thus form extensions, which extend from the area of their connection to the body of this away.
  • the contact region of these contact blades is preferably in the region of the free end of the extensions.
  • a contact blade insert with such trained contact blades is not only easier to manufacture, but it can be formed in particular very well-defined contact areas.
  • the only one-sided connection of the contact blades to their base body allows them to extend oriented in different directions with respect to their longitudinal extent.
  • the contact blades may be arranged to extend radially to each other. For this reason, the contact blade insert can be designed without certain predefined plug directions are given.
  • a complementary blade contact can be contacted as intended by such a contact blade insert, regardless of which direction this is supplied to the contact blade insert. Since the contact blade insert is in a cage receptacle designed as a receptacle, the plug directions are ultimately determined by the possible connector receptacle of the cage. As a rule, you will design the connector receptacle such that it has three plug openings.
  • the contact blades are formed as extensions extending away from their base body. Therefore, the free ends of the contact blades to form a contact area and also to form a ramp surface can be readily formed.
  • the provision of one end connected to the main body contact blades also offers the opportunity to keep a central portion of the contact blade insert. If, in such an embodiment, the primary locking opening of the plug receptacle is located centrally within each side face, the locking pin provided for the primary locking can be used with greater tolerances in the primary locking opening intervene without damaging contact lamellae located below this primary locking opening or obstructing a purposeful insertion.
  • An electrical socket contact 1 comprises a connector receptacle 2, on the back of a Crimpfortsatz 3 is formed, via which the receptacle contact 1 to an electrical conductor, such as a cable can be connected.
  • the plug receptacle 2 has two side parts 4, 4 ', which enclose a receptacle 5.
  • the side parts 4, 4 ' are interconnected by webs 6, 6'. For defined arrangement of the side parts 4, 4 'to each other are on the side part 4' at its the webs 6, 6 'opposite end support webs 7 arranged on the upper side of the free edge of the side part 4 rests.
  • the basic body of the receptacle contact formed from the plug receptacle 2 and the Crimpfortsatz 3 is made of a piece of sheet metal and after punching in his in FIG. 1 been shown canted shape.
  • the Kantachsen for creating the connector receptacle 2 are defined by previously introduced into the metal strip bending grooves.
  • FIG. 1 is a Bending groove marked with the reference numeral 8.
  • the bending grooves 8 continue inside the side parts 4, 4 'in guide grooves.
  • the socket contact 1 also has a contact blade insert 9, which in the illustrated embodiment comprises two interconnected contact blade bodies 10, 10 ', which are arranged parallel to each other.
  • the contact blade insert 9 is also made of a metal strip.
  • the edges of the contact blade body 10, 10 ' are folded outwardly from the plane.
  • the front folds 11 serve as stops when inserting the contact blade insert 9 in the receptacle 5 of the connector receptacle 2 in cooperation with the front end of the connector receptacle 2 to limit the insertion
  • the other folds 12 are designed to be in the bending grooves 8 and in the engage in the side parts 4, 4 'introduced grooves.
  • the folds 12 thus serve to fix the contact blade insert 9 within the receptacle 5.
  • the folds 11, 12 are also clearly in the sectional view of FIG. 2 recognizable.
  • the contact blade body 10 is described in more detail.
  • the contact blade body 10 is constructed accordingly.
  • the contact blade body 10 has a plurality of contact blades K 1 , K 2 .
  • the contact blades K 1 , K 2 of the contact blade body 10 two different lengths are provided, wherein the contact blades K 1 have a longer extent than the contact blades K second
  • the contact blades K 1 , K 2 are designed as extensions of the contact blade body 10 associated base 13 and therefore connected only at one end to the base body 13.
  • the contact blades K 1 , K 2 are radially extending to each other and arranged alternately.
  • the contact blades K 1 , K 2 protrude in the above-described arrangement into a slat space 14 introduced into the main body 13.
  • the fin space 14 is circular in the illustrated embodiment and may also have other geometries depending on the desired configuration.
  • the contact blades K 1 , K 2 have to form each contact area in the region of its free end a bead-like expression 15 (see. FIG. 2 ) on. On the characteristics 15 also a contact thickness is marked. The forms 15 and the contact beads point towards the other contact blade body 10 '.
  • the free end of the Contact lamella K 1 , K 2 is formed as Stützabkantung 16. the - as in FIG. 2 recognizable - slightly spaced from the plane of the wall side 17 of the respective contact blade body 10 and 10 'to the receptacle 5 toward. This ensures that the contact blade insert 9 can be easily inserted into the receptacle 5 of the connector receptacle 2.
  • the contact blade insert 9 is - as in FIG. 1 recognizable - U-shaped, wherein the two contact blade body 10, 10 'connecting bend in the direction of Crimpfortsatz 3 points.
  • the contact blade insert 9 inserted in this way into the receptacle 5 of the plug receptacle 2 is in FIG FIG. 3 played. Due to the design of the contact blade insert 9 and the connector receptacle 2, the receptacle contact 1 can be contacted from three different directions by a blade contact M. This is possible without the contact blade insert 9 having to be inserted in the receptacle 5 in a certain orientation beforehand. If the two contact element bodies 10, 10 'are connected to one another at their connecting end by lugs, the contact lamella insert can basically be contacted from four directions.
  • the front end of the blade contact M is performed in conjunction with the Stauerabkantungen 16 of the contact blades K 1 , K 2 and the contact beads in its intended Kunststoffpositiön.
  • Guide beads in the area of the basic body can additionally support guidance of the blade contact during insertion. It is expedient to provide the strength of the blade contact M so that the Stauerabkantept 16 of the contact blades K 1 , K 2 on the inner surface of the side parts 4, 4 'bear through the blade contact M.
  • the contact regions of the individual contact lamellae K 1 , K 2 then each form a contact bead, which is supported on the inside of the side parts 4 and 4 ', with a short extent, so that a contacting of the outer surface of the blade contact M with a correspondingly high contact force can take place ,
  • the sectional view of FIG. 4 directed. From the description of the contacting of the blade contact M it becomes clear that this is contacted by a large number of contact areas.
  • the side parts 4, 4 'of the connector receptacle 2 each have a primary locking opening 18 or 18', which is centrally inserted into each side part 4 or 4 '.
  • the primary locking openings 18, 18 ' serve for primary locking of the socket contact 1 inserted in a housing. It is basically provided that only one locking pin engages in the primary locking opening 18 or 18' for locking the socket contact 1 in a housing.
  • the symmetrical arrangement of the primary locking openings 18, 18 ' serves the purpose that the socket contact 1 can be used without necessary consideration of its orientation in a socket housing.
