Definitions
- the invention relates to a method for producing a socket contact from a round bar.
- the invention also relates to a socket contact produced according to the method with a hollow-cylindrical contacting area for contacting a corresponding pin contact and a connection area for connecting an electrical conductor.
- the contact elements used extensively in practice are usually manufactured by machining a round rod used as the starting material, with the contact lamellae of the socket contacts being produced by removing the material webs between the individual contact lamellae using a side milling cutter. The resulting contact lamellae of the socket contact are then pressed slightly inwards in order to generate the required spring force. This way of producing a socket contact is very time-consuming, so that the resulting reduced productivity of the production facilities leads to an increase in the costs for the individual socket contacts.
- the socket contact is assembled from two components, namely a sleeve closed on one side and a resilient lamellar basket, which is inserted into the sleeve and attached to it.
- the electrical and mechanical contacting of a corresponding pin contact takes place via the contact lamellae of the lamellar cage, which has a contact area bent inwards for this purpose.
- Such a socket contact is, for example, from DE 10 2012 001 560 A1 known.
- the lamellar cage which is partially arranged inside the sleeve, is bent over the front end of the sleeve onto the outside of the sleeve and is fixed at a fastening point.
- the spring force of the lamellar basket can be adjusted when the socket contact is made by selecting the distance between the attachment point and the front end of the sleeve. The further away the attachment point is from the front end, the lower the spring force of the slatted basket.
- the lamellar basket itself is manufactured by stamping it out of a spring sheet metal strip and then bending the contact lamellae.
- the disadvantage here is that the production of the socket contact is complex and therefore expensive due to the use of two components.
- the socket contact has a relatively large volume due to the combination of the two components, so that it is unsuitable for compact plugs.
- an electrical connection device which consists of three parts, namely a resilient plug contact having several contact lamellae, a sleeve-shaped receptacle which can be connected to an electrical conductor by crimping, and a retaining sleeve for locking the connection device in a corresponding mating connector.
- the resilient plug contact which is punched out of sheet metal and bent, is permanently connected to the sleeve-shaped receptacle by a riveted connection. Because the plug contact, the receptacle and the holding sleeve are made of different materials, they can each be optimally adapted to their respective purpose. However, this advantage is paid for by the increased effort and the associated costs in the production of the contact element.
- the DE 10 2010 020 346 A discloses electrical contact elements in the form of pin and socket contacts, each having a crimp connection as a connection area for connecting an electrical conductor, the connection area being shaped as a hollow cylinder which has a slot in the axial direction.
- the contact area is formed by a hollow cylinder in which wedge-shaped slots are introduced, so that individual spring arms are formed which serve to contact an inserted pin contact. This are produced by machining steps that are not described in detail, so that the production of these socket contacts is also time-consuming.
- JP 2012-221774 A discloses a socket contact with a hollow cylindrical contacting area at one end of the socket contact. Several slits are then milled into the hollow-cylindrical contacting area, which was initially produced by reverse extrusion from a round rod, so that contact lamellae extending in the longitudinal direction and separated from one another by the slits are formed.
- the present invention is based on the object of specifying a method for producing a socket contact from a round bar, by means of which the production time is reduced, so that productivity can be increased, in particular when producing socket contacts by machine.
- the method according to the invention is first of all characterized in that, instead of a machining production, a metal-forming production by means of extrusion and compression molding is provided.
- the contacting area of the socket contact according to the invention has first sections which have a thicker wall, these first sections being connected to one another via second sections with a thinner wall. These when queuing The second sections which are bent or folded outwards from the first sections develop a spring effect which counteracts the first sections bending apart. This increases the contact force with which the inwardly inclined first sections of the hollow-cylindrical contacting area press on an inserted pin contact.
- the production time for producing a socket contact can be significantly reduced.
- productivity i.e. the number of socket contacts produced within a certain time
- productivity can be increased many times over compared to the production of socket contacts on a lathe or milling machine.
- the manufacturing method according to the invention is a non-cutting manufacturing method
- the material utilization is also significantly increased since the starting material is utilized up to 100%.
- the material utilization is also significantly increased in the method according to the invention, so that the individual socket contacts can be produced at lower costs.
- the hollow-cylindrical contacting area is preferably produced by means of forward extrusion or backward extrusion without prior heating of the round rod as the starting material.
- the advantage of cold extrusion lies in the high dimensional accuracy and the high surface quality of the component produced in this way, so that post-processing of the socket contacts produced according to the invention is generally not necessary. After being ejected from the forming press, the socket contacts produced in this way may have to be provided with a coating, but otherwise no longer have to be processed further.
- the first end of the rod is pressed into a die by means of a stamp applied on the back.
- the die which is stationary during the forming process, has the negative shape of the desired hollow-cylindrical contact area, with the punch and the material moving in the same direction during forward extrusion.
- a stamp that has the negative shape of the desired contact area penetrates first end in the round rod. The material is displaced in such a way that it flows into the cavities formed in the stamp in the opposite direction to the direction of movement of the stamp.
- Manufacturing the hollow-cylindrical contacting area by means of extrusion has the further advantage that the fiber layer in the socket contact is much better adapted to the load case than is the case when a hollow-cylindrical contacting area is machined. Furthermore, as a result of the inward pitching of the first sections, internal compressive stresses are introduced into the material, as a result of which the spring action of the first sections serving as contact lamellae is improved.
- the hollow-cylindrical contacting area previously produced by extrusion is inserted into a die for the positioning of the first sections.
- the die has webs tapering conically inwards, which are arranged corresponding to the first sections.
- the first sections position themselves in accordance with the conical taper of the inner cross-section of the die, while the second sections with a thinner wall thickness compensate for the decreasing circumference of the hollow-cylindrical contacting area by arching outwards.
- corresponding recesses are formed in the matrix between the webs, which enable a corresponding outward bending or folding of the second sections.
- a corresponding mandrel is arranged in the hollow-cylindrical contacting area while it is being moved into the die. This ensures that the second sections with the thinner wall thickness cannot fold or bulge inwards when the hollow-cylindrical contacting area is moved into the die.
- the second sections are pressed by the mandrel into the corresponding recesses in the die, so that the second sections are given a desired, defined contour.
- the socket contact has a connection area which is located at a second end of the socket contact, ie at the end facing away from the contacting area.
- a connection area is preferably produced in a first method step by means of extrusion.
- the connection area is preferably designed as a hollow cylinder, the connection area being a crimp connection.
- Such a connection area can also be produced in a simple and cost-effective manner by extrusion, in which case the inner cross section of the connection area can be circular in the simplest case, with a constant diameter over the length of the connection area.
- connection area in a first method step, i. H. at the beginning of the manufacturing process of the socket contact has the advantage that the connection area can then be used during the manufacture of the hollow-cylindrical contacting area to accommodate a stamp or counter bearing during forward extrusion or reverse extrusion.
- a funnel-shaped collar is preferably formed in a further method step at the outer end of the connection area by expanding.
- the formation of a funnel-shaped collar makes it easier to insert a conductor into the connection area.
- the formation of an expanded, funnel-shaped collar also makes it possible for the end of the conductor insulation to protrude into the collar in the case of an insulated conductor, while the stripped conductor or the stripped strands are inserted in the hollow-cylindrical connection area. This can prevent damage to the conductor or the strands at the outer end of the connection area.
- the aforementioned object is achieved in the case of a socket contact described at the beginning with a hollow-cylindrical contacting area and a connection area with the features of patent claim 7 in that the hollow-cylindrical contacting area has first and second sections which extend in the longitudinal direction of the contacting area and are formed alternately next to one another in the circumferential direction of the contacting area are.
- the first sections have a thicker wall and the second sections have a thinner wall.
- the first sections with thicker wall thickness are inwards employed, while the second sections with thinner wall thickness are bent or folded outwards.
- the first sections of the contacting area which are set inwards, serve as contact lamellae, which mechanically and electrically contact a pin contact inserted into the contacting area of the socket contact.
- the outwardly curved second sections generate an additional spring force, with which the first sections are pressed against an inserted pin contact.
- the second sections thus have a similar effect to an overspring plugged onto a conventional socket contact, but without two separate components having to be joined together for this purpose.
- the angle of attack ⁇ with which the first sections with a thicker wall thickness are inclined inwards, can be set within certain limits, so that the contact force acting on a specific pin contact can be adjusted via the angle of attack realized during production of the socket contact.
- the setting angle ⁇ of the first sections is preferably no more than 10°, in particular no more than 5°, which means that the second sections do not have to be bent outwards too much.
- a solid central area is formed between the hollow-cylindrical contacting area and the hollow-cylindrical connection area.
- This solid central area preferably extends over at least 25% of the total length of the finished socket contact.
- the extension of the middle area is preferably approximately the same size as the extension of the connection area, while the contacting area preferably has a slightly larger extension than the middle area or the connection area.
- at least one stop can also be formed on the central area.
- FIG. 1 shows a perspective representation of a pre-geometry 1 'of the socket contact 1 according to the invention, ie the socket contact 1 in the not yet completely finished state.
- a hollow-cylindrical contacting area 2 has been produced at a first end 3 of the socket contact 1 or the pre-geometry 1' by means of extrusion.
- the hollow-cylindrical contacting area 2 has first sections 4 and second sections 5 extending in the longitudinal direction L, which are formed alternately next to one another in the circumferential direction of the hollow-cylindrical contacting area 2 .
- the first sections 4 have a thicker wall thickness d 1 and the second sections 5 have a thinner wall thickness d 2 .
- the wall thickness d 1 of the first sections 4 is significantly thicker than the wall thickness d 2 of the second sections 5, in particular at least twice as thick.
- connection area 7 is formed as a hollow-cylindrical crimp connection at the second end 6 of the socket contact 1, the connection area 7 also having been produced by extrusion.
- the connection area 7 has a funnel-shaped collar 8 which has been produced by widening the connection area 7 .
- the funnel-shaped collar 8 makes it easier to insert a conductor to be connected, in particular a stranded conductor, into the connection area 7 before the conductor is firmly and electrically conductively connected to the socket contact 1 by crimping.
- the socket contact 1 also has a solid central area 9 which is formed between the hollow-cylindrical contacting area 2 and the hollow-cylindrical connection area 7 .
- a stop 10 is formed on the central region 9 and can serve as a stop for fastening the socket contact 1 in a housing wall or a carrier plate.
- the angle of incidence ⁇ of the first sections 4 is drawn in, which is preferably less than 10°, in particular less than 5°.
- the setting angle ⁇ can be adjusted within certain limits during the manufacture of the socket contact 1, as a result of which the socket contact 1 and in particular its contact force can be adapted to a pin contact to be contacted.
- FIG. 4 shows various steps in the production of the socket contact 1 from a solid round bar 11 as the starting workpiece.
- a first punch 12 is pressed into the rod 11 at the second end 6 , as a result of which the material of the rod 11 is displaced in such a way that it flows in the opposite direction to the direction of movement of the punch 12 .
- the hollow-cylindrical connection area 7 is produced in the first method step.
- the outer end of the hollow-cylindrical connection area 7 is widened, as a result of which the funnel-shaped collar 8 is formed.
- a second die 13 which has the negative shape of the desired contacting area 2 , is pressed into the round rod 11 at the first end 3 .
- the material of the rod 11 is also displaced during this reverse extrusion in such a way that it flows in the opposite direction to the direction of movement of the punch 13 into the recesses 14 formed in the punch 13 .
- the socket contact 1 essentially has a shape or geometry that corresponds to that in 1 shown pre-geometry 1 'of the socket contact 1 corresponds.
- the contacting area 2 has first sections 4 with a thicker wall thickness d 1 and second sections 5 with a thinner wall thickness d 2 .
- the webs are arranged to correspond to the first sections 4 of the contacting region 2, so that the first sections 4 are positioned inwards in accordance with the conical narrowing of the inner cross section of the matrix 15.
- the second sections 5 with a thinner wall thickness compensate for the decreasing circumference of the hollow-cylindrical contacting area 2 by arching outwards.
- corresponding recesses are formed in the matrix 15 between the webs, which enable the second sections 5 to bulge outwards.
- a mandrel 16 is arranged in the hollow-cylindrical contacting area 2 during this method step.
- the mandrel 16 has it a geometry similar to that of the stamp 13, so that recesses 17 are formed in the mandrel 16, which receive the first sections 4 of the contacting region 2.
- the mandrel 16 has webs 18 formed between the recesses 17 which prevent the second sections 5 of the contacting region 2 from bulging inwards when they are inserted into the die 15 .
- the socket contact 1 When the contacting area 2 of the socket contact 1 is moved back out of the die 15, the second sections 5 are pressed by the mandrel 16 or its webs 18 into the corresponding recesses in the die 15, so that the second sections 5 receive the desired, defined contour. After this production step, the socket contact 1 is finished and can be provided with a coating if required.
