Definitions
- the present invention relates to a contact socket for a plug-socket combination according to the preamble of claim 1.
- Such plug-socket combinations are known, for example, from DE-C-197 22 543.
- a contact socket which in turn consists of a socket contact and a spark protection sleeve pushed onto the socket contact.
- the spark protection sleeve is plastically deformed to form a positive fit on the socket contact.
- the contact lamellae forming the contact piece of the socket contact are bent inwards in order to produce a certain pretension of the socket contact.
- the disadvantage here is the high forces that must be applied when deforming the spark protection sleeve on the one hand and when deforming the contact blades on the other. This causes misalignment of the actual insertion opening or contact opening on the contact piece of the socket contact on the one hand with respect to the insertion opening on the spark protection sleeve on the other hand.
- this means that the spark protection sleeve is usually pressed in or caulked in at four points opposite each other in order to link part of the spark protection sleeve to the socket contact;
- an annular groove can be provided in the socket contact, in which the deformed areas of the spark protection sleeves then engage in the manner of barbs.
- a contact sleeve with a lamellar spring is known from DD-C-67484, in which the lamellar spring is fixed flush with two webs in a sleeve.
- the disadvantage here is the required high dimensional accuracy in the area of the plane surfaces formed by the webs on the one hand and the areas of the sleeve adjoining them.
- the object of the invention is to design a contact socket in such a way that misalignments are avoided as far as possible.
- the solution to the problem is an only reversible deformation of spark protection sleeve and socket contact when joining both parts.
- the contact piece on the contact socket should only be reversibly deformed with respect to the spark protection sleeve.
- the socket contact in the spark protection sleeve.
- the socket contact only has to be pressed into the spark protection sleeve. So there are no deformation forces on the spark protection sleeve.
- the socket contact is pressed into the spark protection sleeve in the direction of the central longitudinal axis of the socket contact, which is essentially congruent with the central longitudinal axis of the spark protection sleeve in the final assembly state, so that misalignments are avoided.
- the design of the fixing of the socket contact in the spark protection sleeve as a press fit also has the advantage that the socket contact is inserted into the spark protection sleeve in one operation and fixed by means of the press fit. is fixed. Compared to the type of production according to the state of the art, where the deformation of the spark protection sleeve follows the production process of inserting the socket contact into the spark protection sleeve. One production step is therefore saved compared to the prior art.
- a sawtooth profile on the socket contact according to claim 3 is simple in terms of production technology.
- it is a profiled sawtooth ring encircling in the manner of a thread.
- These all-round sawtooth rings are pressed together with areas of the inner surface of the spark protection sleeve. This measure already makes it possible to tolerate large fluctuations in tolerance
- Spark protection sleeve inner diameter compared to just such - ( to compensate for tolerance fluctuations in the socket contact outer diameter.
- teeth or toothed rings of different tooth heights according to claim 4 is particularly advantageous for compensating for tolerance fluctuations.
- a circumferential collar provided on the socket contact is used according to claim 5. It is particularly advantageous to provide this collar - as suggested in claim 6 - in relation to the central longitudinal axis of the socket contact next to the sawtooth profile , In this way, the quality control during production is very easy. It is only necessary to measure the pressing force exerted during the pressing on the one hand and the pressing distance covered by both pressing parts, namely the spark protection sleeve on the one hand and the socket contact on the other hand, in order to compare the two actual sizes with the specified target sizes. If this comparison is positive within the specified tolerance fluctuations, it is a good part. Otherwise it is a committee part.
- the contact piece on the socket contact is designed as a slotted hollow cylinder, so that individual contact blades form the socket contact.
- the contact lamellae Since the overall height of the projections is the same, the contact lamellae always deform by the same amount, so that the contact lamellae are thus deformed identically and are therefore preloaded identically.
- the surfaces of the projections form a virtual circle, the diameter of which, when the socket contact is inserted into the spark protection sleeve, corresponds to the inside diameter of the spark protection sleeve, so that all the slats are bent inwards by the same distance, i.e. are deformed by the same amount relative to the insertion opening of the spark protection sleeve, so that Alignment errors are excluded.
- each lamella has a circular segment-shaped projection on its outer surface.
- These projections which extend over the entire lamella width, have the advantage of a particularly large and uniform contact surface of the circular segment-shaped projections on the inner walls of the spark protection sleeve, which has a positive influence on the deformation accuracy of the lamella contacts.
- the use of the projections has the further advantage that, due to their relative position - with respect to the central longitudinal axis - of the contact piece on the socket contact, the contact lamellas are pretensioned and thus their
- Spring characteristic can be influenced infinitely, as it were. If the projections are placed at a great distance from the insertion opening of the socket contact, the remaining lever arm and thus the spring travel of the individual lamellae is very large. If, on the other hand, the projections are attached very close to the area of the insertion opening of the socket contact, the contact lamella yield only very slightly, ie they have only a very small spring travel. It should be expressly mentioned that it is of course also conceivable to provide the claimed press fit without the reversibly deformed contact lamellae and conversely to combine the reversibly deformed contact lamellae with another connection between spark protection sleeve and socket contact.
- Fig. 1 is an exploded view of the socket contact shown on the left in the drawing figure before joining with the spark protection sleeve and shown on the right in the drawing
- Fig. 2 shows the fully assembled contact socket with the socket contact completely pressed into the spark protection sleeve.
- the socket contact 1 comprises four areas along its longitudinal contact axis 2 in FIG. 1 from left to right, namely a conductor insertion area 3, a circumferential collar 4, a sawtooth profile 5 and a contact piece 6.
- the sawtooth profile 5 is in turn formed from individual circumferential sawtooth rings 7 arranged next to one another.
- the contact piece 6 is originally hollow cylindrical and has multiple slits to form contact lamellae 8. In the exemplary embodiment, four slots 9 are slotted into the contact piece 6.
- each contact lamella 8 there is a projection 10 in the form of a segment of a circle.
- This projection 10 in the form of a segment of a circle is beveled conically toward its side facing away from the sawtooth profile 5 in order to form contact surfaces 11.
- the socket contact 1 is inserted into the spark protection sleeve 12 shown in FIG. 1 to the right of the socket contact 1 and pressed with it.
- the contact surfaces 11 of the projections 10 then engage with the inner surfaces 13 of the spark protection sleeve 12 in such a way that the contact lamellae 8 approach one another in the transverse direction 14 running perpendicular to the longitudinal axis 2 of the contact center be bent.
- the contact surfaces 11 of the projections 10 therefore abut the inner surfaces 13 of the contact sleeve 12 and deform the contact blades 8 reversibly toward one another in the transverse direction 14.
- the position of the projections 10 on the contact blades 8 allows the respective spring travel of the contact blades to be set to a certain extent in a stepless manner become. If the projections 10 in the exemplary embodiment according to FIGS. 1 and 2 are displaced further to the right along the longitudinal axis 2 of the contact center, the effective lever arm of the contact blades 8 is reduced.
- the contact lamellae can then no longer spring as far as when the projections 10 are arranged near the sawtooth profile 7, as is the case with the exemplary embodiment shown in FIGS. 1 and 2.
- the sawtooth profile 5 When the socket contact 1 is inserted into the spark protection sleeve 12 or when the spark protection sleeve 12 is pushed onto the socket contact 1, the sawtooth profile 5 also comes into engagement with the inner surface 13 of the contact sleeve 12. A pressing force is then applied to the socket contact so that the individual sawtooth rings 7 of the sawtooth profile 5 deform to form a press fit with the sleeve 12.
- the path corresponding to the profile length 15 of the sawtooth profile is measured until the spark protection sleeve ends 16 abut the collar 4. If these two values correspond to the specified target values, it is a good part.
- connection opening 20 for a conductor (not shown in the drawings) for the electrical contacting of the contact socket essentially consisting of the socket contact 1 and the contact sleeve 12.
