Definitions

• the present invention relates to a plug socket according to the preamble of claim 1, i.e. to a plug socket, which can be coupled to a plug part by means of a plug connection and can be electrically contacted.
• Plug connections with contact areas arranged in the form of a hyperboloid have long been known as HYPCON plugs.
• An example of a corresponding plug socket with hyperbolic contact areas is shown in FIG. 3.
• this known plug socket has an essentially cylindrical socket body 22 which is comparatively thin-walled and hollow on the inside.
• a plurality of contact wires 23 are arranged inside the socket body 22, these contact wires 23 being arranged with respect to the longitudinal axis of the plug socket with such an inclination angle that they delimit a body having the shape of a hyperboloid inside the socket body 22, so that the contact wires 23 are hyperbolic and arranged contact areas for a in the plug socket, ie in the interior of the socket body 22, form the plug part to be inserted.
• the plug part has in particular a contact pin, the outer shape of which is complementary to the socket body 22. Diameter values of 0.6 mm, 0.76 mm, 1.0 mm, 1.5 mm, 3.5 mm, 7 mm or even 15 mm etc. are common as the outer diameter of the contact pin and correspondingly as the inner diameter of the socket body 22.
• the contact wires 23 inserted into the socket body 22 are preferably made of bronze.
• the ends of the contact wires 23 which protrude beyond the lateral boundaries of the socket body 22 are bent over as shown in FIG. Due to the special design of this so-called.
• These connectors have excellent electrical and mechanical properties.
• HYPCON connectors are used wherever extremely high contact reliability is required, e.g. in computer-controlled devices.
• current with a current of up to 6 A can be transmitted.
• higher currents up to 150A can be transmitted.
• the plug socket required for such a plug connection is constructed in a relatively complicated manner and can therefore only be produced with great effort.
• this plug socket consists of a large number of individual parts which first have to be assembled.
• a plurality of contact wires 23 must be inserted into the socket body 22 with a certain angle of inclination with respect to the longitudinal axis of the socket body 22, so that these Contact wires 23 delimit the hyperbolic body.
• Socket body 22 with the contact wires 23 inserted therein are inserted in two halves 20 and 21 of an outer housing, these outer halves 20 and 21 being connected to one another, for example.
• the manufacturing process of the known plug socket shown in FIG. 3 is therefore very complex, so that a fully automated production of this plug socket is not possible.
• the present invention is therefore based on the object of designing a plug socket in accordance with the preamble of claim 1 in such a way that it can be produced in a simple manner.
• the connector socket should be cheap, quick, easy and fully automated to manufacture.
• the plug socket according to the present invention is formed in one piece, i.e. can be made from a single workpiece.
• the socket is made from a one-piece stamped part which is bent into the desired socket shape.
• the contact areas arranged in the form of a hyperboloid are formed by lamellae which are formed in the stamped part.
• the lamellae are initially formed essentially parallel to one another in the stamped part and are then formed by twisting and upsetting such that they delimit a hyperboloid-like body.
• the plug socket advantageously also has a fastening section to which a conductor can be fastened on the one hand and this conductor can be electrically contacted on the other hand.
• the conductor is attached and electrically contacted in particular in the form of crimping.
• Fig. 1 shows the top view of a stamped part which is used to produce a
• Plug socket is used according to the present invention.
• Fig. 2 shows a socket according to the present invention in a perspective view
• FIG. 3 shows a known plug socket with hyperbolic contact areas in a perspective partial cross-sectional view.
• Fig. 1 shows a plan view of a punching tape 14, which in particular made of an electrically conductive material, such as a bimetal.
• a production part 15 is punched out of the punched strip 14, from which the plug socket shown in FIG. in particular is bent.
• the stamped part 15 has - as an essential component - a lamella area 13 which serves as an active contact area in the subsequent plug socket.
• the lamella area 13 has a plurality of substantially parallel and equidistant elongated lamellae 7, which remain by punching out corresponding intermediate areas 16. Adjacent to these slats 7, a plurality of tongues 5 are punched out, with the embodiment shown in FIGS. 1 and 2 in particular there are four tongues, the width of which is identical and which are arranged equidistantly.
• the tongues 5 form a stabilization area 12, which serves to stabilize the actual contact section in the connector socket subsequently produced therefrom.
• the stamped part has a plurality of tabs 8, 9 and 10, the tab pairs 8 and 9 serving as contact area 11 for electrical contacting of a conductor to be connected to the plug socket.
• the length of the tabs 8 and 9 is different, so that different conductor diameters in the form of a crimp connection can be contacted with the tab pairs 8 and 9.
• a conductor diameter of 1.5 to 2.5 mm 2 can be contacted with the tabs 8 and a conductor diameter between 4.0 and 6.0 mm 2 can be contacted with the tabs 9.
• the further pair of tabs 10 is provided for fixing the electrical conductor to be connected to the plug socket, these tabs 10 also being bent in the sense of crimping and in this way being able to grip around and fix the insulation jacket of the electrical line.
• the tabs 10 thus also serve as strain relief.
• the tabs 10 are advantageously configured wider than the contact tabs 8 and 9.
• an elongated transition area 2 is formed, which has a guide bore or a guide hole 4 for an automatic crimping machine, so that the contacting and fixing of the electrical conductor described above, which is to be connected to the plug socket , can be carried out automatically with a crimping machine.
• the stamped part is preferably made of a bimetal, which consists of a base material and a very highly conductive material, which forms the lamella or contact area 13.
• This electrically highly conductive material can also be applied to the base material in a known manner, such as by rolling or galvanic application.
• a resilient or resilient material such as beryllium copper, is advantageously chosen as the base material, which after inserting or removing the plug pin from the socket into the Initial state springs back. Silver or, in particular, gold can be considered as material for the lamella or contact area 13.
• the stamped part 15 shown in FIG. 1 is bent as follows to form the exemplary embodiment of the plug socket according to the invention shown in FIG. 2.
• the lamella region 13 is first rotated and compressed, so that the hyperbolic profile of the lamellae 7 that is typical for this type of connector is obtained after the lamella region 13 has been bent into the cylinder-like shape shown in FIG. 2. That
• the tongues 5 are folded or bent outwards in such a way that they form the outer surface of the contact section 1 of the plug socket and in particular stabilize the lamellae 7.
• the transition region 6 shown in FIG. 1 between the lamella region 13 and the tongues 5 represents an upper bending edge 6 in the case of the plug socket shown in FIG. 2, which has been produced from the stamped part 15 shown in FIG. 1.
• the pairs of lugs 8-10 are finally bent as shown in FIG. 2 in order to make electrical contact (with the aid of the lugs 8 and 9) to a conductor which can be connected to the plug socket or (with the aid of the lugs 10) to fix this conductor.
• the tabs 8 and 9 form a crimp connection with the conductor.
• the tabs 10 are also bent in the form of a crimp in order to encompass and fix the insulation jacket of the electrical conductor.
• the tabs 8-10 thus form a fastening section 3, while the tongues 5 and the slats 7 form the previously mentioned contact section 1 of the socket shown in FIG. 2.
• the plug socket according to the invention can be produced in a very simple manner without the excellent electrical and mechanical properties of a HYPCON plug connection described above being lost.
• the plug socket according to the invention is designed in one piece, so that the material costs can be minimized.
• the plug socket according to the invention is bent from a single stamped part which has previously been punched out of an electrically conductive material, for example a bimetal. The manufacture of the plug socket according to the invention is thus significantly simplified and cheaper compared to the prior art shown in FIG. 3 and can in particular be carried out fully automatically.
