The inner sleeve 26 is with four grooves 26 extending in the direction of the longitudinal axis are provided, which are arranged at equal intervals in the circumferential direction are. The grooves 28 are mutually identical, that is, they have the same depth and the same width over their entire length and have a rectangular cross-section in the exemplary embodiment.

The middle sleeve 30 1st see with an inner diameter ver w which gives a tight, secure fit together with the outer jacket surface of the sleeve 26th In the outer circumferential surface of the longitudinal axis extending grooves 32 are arranged in the direction that is the same size and shape as the grooves 28. The grooves 32 are disposed circumferentially at equal intervals "As a comparison of FIGS shows ₀ 3aa and 3bb, the axial The length of the sleeve 30 is significantly less than that of the sleeve 26. The reason for this difference in length is explained below.

The third, from sere sleeve 3 * 1 is provided Rait an inner diameter, »OCE _a when the sleeve 3Ί .is pushed onto the sleeve 30, a close, tight fit results _o the axial length of the sleeve 34 is less than that of the middle sleeve 30, as also shown in FIGS. 3bb and 3cc «

A straight, elongated lamellar contact element 36 is firmly fitted into each of the grooves 28 of the inner sleeve 26. Furthermore, the length of the contact elements 36 is essentially the same as the length of the sleeve 26 _S, as shown in FIG. 3aa "A suitable adhesive can be used to fasten the contact elements 36 in the associated grooves 28" Grooves 28 can, however, also be selected so that the contact elements 36 are firmly clamped therein.

If all contact elements 36 are in the grooves 28, the Sleeve 30 pushed over and in a in Flg. 6 position shown This position is chosen so that each one end zone the sleeve 26 remains uncovered. The outer surface of each contact element 36 is preferably curved so that it in the cylinder surface formed by the jacket surface of the sleeve 26 lies. Because the sleeve 30 is pushed over the sleeve 26 and the contact elements 36 with a tight fit, the latter are also held in place by the sleeve 30 »

.End can be referred to as the connection end, since the former is used for insertion into the socket and the latter is used to connect the electrical lines. The plug ends of the sleeves 26 and 30 are of the same length. If necessary, however, these lengths can also be chosen differently. At the connection end, the inner contact elements 36 are longer than the contact elements 38, beyond which they protrude in the axial direction. This configuration allows the electrical wires without difficulties λ rigkelten with the connection ends of the contact elements 36 to connect, for example by soldering or welding. This advantage is particularly important when the coupling element has a very small diameter. In a corresponding manner, the contact elements protrude beyond the sleeve 34. In the area of the shoulder formed by the sleeve 30, the outer surface of the contact elements 38 is accessible for the connection of electrical lines. The routing of the electrical lines connected to the connection ends of the contact elements is shown schematically in FIG. 1 ″.

At the connector end, the contact elements 36 and 38 are in the Sleeves 28 or 30 embedded, but the outer surface of the contact elements 36 and 38 is along the length of the through the sleeves 26 or 30 formed paragraphs are completely exposed · These surfaces preferably form the contact »

In some cases, however, it may be desirable that the contact elements 36 and 38 protrude slightly from the outer surface of the sleeves 26 and 30, which will be discussed later.

The ends of the sleeves 26 and 30 and the contact elements 36 and 38 are designed so that they form Susanne pawls. The axial section of the plug end of the sleeve "28 shows that the stacker surface is slightly corrugated and has a dome MO at the end." A valley 42 adjoins this dome 40 inwardly. The plug or contact end 3 of the contact elements 36 is designed in the same way as was shown in FIG. 3aa, in which the valley is designated with 42a and the top with 40a educated.

As FIG. 6a in particular shows, directly below the contact end 43 of the contact elements 36 and 38, the corresponding parts of the sleeves 26 and 30 are undercut or formed in such a way that a wedge-shaped slot or gap 44 is present can be of the elements 36 and 38 radially inwardly until it abuts against the? 3n formed of the sleeve surface of the gap 44 · bent it is, therefore, that the zweekmässlg is resilient KontEktends 43, so that it in the position shown in Figure ₃ position 6a

is _p that an additional ring set of contact elements to the üusseren Ringsatss 38 around is arranged coaxially with and above a further bush is pushed ο Therefore entsprechend® parts with the same reference numerals "However, with the additional index" b "provided The sleeve 3 ¹ Ib is designed in the same way as the sleeve 34 according to FIG. ₀ 4 with the "exception that it is provided on its outer circumferential surface with axially extending grooves 76 which cover the contact elements 38 in the radial direction" as Pig, 12 showed the grooves 76 are much narrower than the grooves in the inner sleeves and correspondingly narrower contact elements contain 78 ₀ Apart from the fact that these contact elements 78 have a smaller cross sectional area than the contact elements 38b are formed in the same catfish as the latter, and with Contact ^{ends 1} IJb that are identical to the contact ends $ 3 o Corresponding contacts are also in the plug socket, not shown, is provided, - the plug socket is designed in the same way as the plug shown in Fig. 12 with the exception that it has a recess corresponding to the plug part »

As can be seen from Flg _c 12, all contact elements 78, which are referred to as auxiliary pins in the following, are aligned in the radial direction with the right-hand side or edge of the associated contact element 380 when viewed from the center / 10 from that of the contact elements 38.

The (StUIiA for this® arrangement and the large ratio 9 09881/0490

can be better explained if the circuit also shown in Fig. 12, with which the embodiment can be used together, is considered. One of the pins 78 is connected to a relay coil 80 of such a circuit. The other end of the coil 80 is not connected to one pin shown 78 of the plug socket connected In series with the coil 80, a battery 82 is connected in "When the plug geraäss FIG ₀ 12 and the associated socket are brought together so ^ that the pins 78 have contact with each other, the relay 80 is energized and thus the switch 81 closed. The switches 84 are connected to the radially adjacent contact elements 38 in such a way that they feed a circuit connected to the contact element 38b. In other words, this means that the current circuits in which the contact elements 38b are, will not be fed until the Kontakteiemente 78 of the plug and the socket have touched _e Assuming that the power 38b of the contact elements in the case of a Contact is to be transmitted is considerable, then considerable arcs or sparks could occur ο By means of the circuit described above and the auxiliary pins, it is achieved that the high power or voltage is only supplied to the contacts 38b after the contact elements 78 have been brought into contact with one another ο

When using such auxiliary pins geraäas _o Figure 12, the plug and socket are first inserted into each other so that none of the contacts with the mating contact has contact "

Then the two coupling points are rotated against each other in such a way that the contact elements 38b of the plug and the socket are the first to come into contact with each other and cover each other in their contact surfaces to 9/10., Before the auxiliary pins 78 come into contact with each other ₀ At that moment in will produce the auxiliary pins contacts, the associated relay 80 will be energized and the switch 84 actuated by them closed, so that now fed only the circuits of the contacts 38b _0th Through the described arrangement and design of these auxiliary pins it can be achieved that the contact elements 38b only come under tension when they have almost completely pushed one another, whereby arcs and sparks are avoided.

Since it is possible with the coupling elements according to the invention to accommodate a large number of contact elements in a very small, cylindrical space, it is possible to obtain outer dimensions of the coupling element that match the outer dimensions of a cable and a cable harness with which the may be used coupling element "This reduces ^7, the problems of weight, of the space of the seal, ventilation and derglc, where a large significance ₃ also opens the principle of the invention underlying the possibility of a quick separation, which in most applications such as cable harnesses, such as those used to connect different parts of electronic devices, are very desirable and important Isto
