Definitions

• the present invention relates to the field of releasable connection technology of coaxial cables. It relates to a coaxial connector arrangement according to the preamble of claim 1.
• Such a connector arrangement is e.g. known from EP-B1-1 222 717.
• FIGS. 1-4 A known embodiment of such a QMA connector system, as manufactured and offered by the applicant, is shown in FIGS. 1-4.
• the system comprises two mating connectors 10 (male; Fig. 1, 2) and 20 (female; Fig. 3,4) which are automatically inserted into each other in a latching manner while generating and maintaining sufficient axial contact pressure and later by actuating an axially displaceable actuating sleeve (15 in Fig. 1, 2) can be solved again.
• the male connector 10 which is shown in FIG. 1 in longitudinal section and in FIG. 2 in a perspective side view, comprises a cylindrical housing 11, which is coaxial with a plug axis 17 and serves as an outer conductor, with a coaxial through-bore 11 'which is stepped in diameter, in which an inner conductor contact 12 is arranged concentrically isolated by means of an insulating piece 13.
• a coaxial through-bore 11 ' which is stepped in diameter, in which an inner conductor contact 12 is arranged concentrically isolated by means of an insulating piece 13.
• In the front part of the connector 10 is in the through hole 11 'in contact with the housing 11
• Clamping sleeve 14 is firmly inserted, in which a ring of hook-shaped, radially resilient locking fingers 19 is formed by a plurality of axial slots 18.
• an axially displaceable actuating sleeve 15 encloses the housing 11 on the outside.
• At the front end of the actuating sleeve 15 is a conically tapering on the inner edge
• Unlocking ring 29 is formed, which engages in the ring of the locking fingers 19 and bends them radially outwards when the actuating sleeve 15 is moved axially backwards.
• a clamping sleeve 16 is provided, with which the coaxial cable can be attached to the connector 10.
• the associated female connector 20, which is also shown in FIGS. 3 and 4 in section and in a perspective side view, comprises a housing 21, which is coaxial with the connector axis 28 and serves as an outer conductor, with a concentric through-bore 21 'and one by means of an insulating piece 24 in FIG Through hole 21 'concentrically held inner conductor contact 22.
• the inner conductor contact 22 has a slotted contact socket 23 at the front end, into which the inner conductor contact 12 of the male connector 10 enters when the plug connectors 10, 20 are plugged together.
• the outer conductor contact is produced by a contact sleeve 25 enclosing the insulating piece 24, with which the plug connector 20 moves into the clamping sleeve 14 of the plug connector 10 when it is inserted and touches the bottom of the clamping sleeve 14.
• a clamping sleeve 26 is also provided for fastening the coaxial cable.
• the resilient locking fingers 19 of the clamping sleeve 14 slide with their front, hook-shaped ends over a circumferential bead 27 formed on the outside of the contact sleeve 25, which slowly increases in diameter and then drops comparatively steeply. In this way, the latching fingers 19 snap behind the bead 27 and impress the contact sleeve 25 with a force acting in the plug-in direction, as described in the aforementioned document EP-B1-1 222 717.
• the locking of the clamping sleeve 14 and contact sleeve 25 can be canceled again by means of the actuating sleeve 15.
• the object is achieved by the entirety of the features of claim 1.
• the solution according to the invention is characterized in that one or more seals are arranged within the clamping means, which seal the space between the contact sleeve and the through hole of the second connector in the assembled state.
• the at least one seal is accommodated in the housing of the second connector, if a circumferential annular groove is provided in the inner wall of the through hole of the second connector, and if the at least one seal is designed as an O-ring and is arranged in the annular groove.
• the clamping sleeve is firmly inserted into the through hole of the second connector and that the at least one seal is arranged on the clamping sleeve.
• Clamping sleeve an axially displaceable actuating sleeve is provided, which surrounds the two connectors on the outside when plugged in, and that the actuating sleeve is sealed with respect to both connectors.
• Fig. 1 in longitudinal section the male connector of a coaxial
• FIG. 2 shows the connector from FIG. 1 in a perspective side view
• FIG. 3 shows, in longitudinal section, the female connector from the prior art which matches the male connector from FIG. 1;
• Fig. 4 shows the connector of Fig. 3 in a perspective side view
• a plug connector arrangement according to a preferred embodiment of the invention is shown in detail in longitudinal section, in Fig. 6 the associated male connector, in which the arrangement is sealed, on its own.
• the connector arrangement 30, 30 of the exemplary embodiment comprises a male connector 30 and a female connector 40.
• the female connector 40 can in principle be configured in the same way as in the prior art (FIGS. 3, 4). It has a cylindrical, as
• the contact socket 43 receives the inner conductor contact 32 (FIG. 6) of the male connector 30.
• the housing 41 of the connector 40 merges at the front end into a contact sleeve 45, which is inserted into the other connector 30 and produces the external conductor contact there.
• a circumferential bead 46 is formed in a manner known per se, which has a slowly rising on the front
• Diameter enlargement on the other hand, it has a comparatively large decrease in diameter.
• the bead 46 is used in conjunction with an adapter sleeve 34 on the male connector 30 to latch the two connectors 30, 40 and to generate an axial contact force which presses the contact sleeve 45 with the end face in contact with a diameter step 49 in the connector 30.
• the male connector 30 (FIG. 6) also has a cylindrical housing 31 (not fully shown in FIGS. 5, 6) with a through bore 48 coaxial with the plug axis 47.
• the through hole 48 has a diameter step 49, on which the contact sleeve 45 of the other connector 40 is placed in the inserted state.
• the inner conductor contact 32 protrudes with its front end beyond the diameter step 49 and thus forms a contact plug matching the contact socket 43.
• a coaxial clamping sleeve 34 is slid onto the front end of the housing 31, on which spring-elastic locking fingers 37 are formed by multiple axial slits, which engage with their front, hook-shaped ends around the front end of the housing 31 and radially into the through hole 48 protrude.
• An actuating sleeve 35 is arranged axially displaceably coaxially above the clamping sleeve 34 and, by means of a conical unlocking ring 36, can radially bend the latching arms 37 for unlocking behind the bead 46 when the actuating sleeve 35 is pushed backwards (in FIG. 6 downwards) becomes.
• the plug connector 40 By means of the clamping sleeve 34 attached to the outside on the housing 31, the plug connector 40, when the plug connector arrangement is in the assembled state, bears directly on the inner wall of the through bore 48 and on the diameter step 49 with the contact sleeve 45.
• This configuration offers the possibility of sealing the contact area to the outside in a particularly simple manner by means of a seal arranged between the contact sleeve 45 and the inner wall of the through bore 48.
• a seal 39 is accommodated in the exemplary embodiment of FIGS. 5, 6 for reasons of space in an annular groove 38 in the inner wall of the through bore 48 and is preferably designed as an O-ring.
• Several seals can also be arranged axially one behind the other, but this increases the insertion forces.
• the contact area of the outer conductors at the diameter step 49 is through the seal 39 and the inner conductor contacts in the contact socket 43 are sealed off from the outside space.
