Definitions

  • the invention relates to an arrangement of a connector part, such as socket or plug, and a filter array device.
  • filter plugs are known in which a filter array is accommodated in the housing of a connector part. If you want to achieve a different filter effect, the entire filter plug must be replaced; the same applies if a line passage without a filter effect is desired. In the known filter plugs, the filter array can only be checked with the plug housing or the socket housing.
  • Such filter plugs are already known from US-A-3573677 and GB-A-2014804
  • the aim of the invention is to provide an arrangement of the type mentioned, in which a filter array can be retrofitted to a connector part, so that a preliminary test of the connected filter array is possible without a connector or socket housing, without a maximum overall length of the arrangement must be exceeded.
  • the invention provides an arrangement in which the connector part has a base body surrounded by a housing jacket, in which there are provided connecting contacts extending to a connection side of the connector part, each of which is formed at its rear end facing away from the connection side into a contact socket, and in which the filter array device has a filter body penetrated by contact pins, characterized in that the filter body is surrounded by an essentially collar-shaped, resilient ground connector which projects beyond an end face of the filter body opposite the rear side of the connector part, wherein the connector part and the filter array device are matched to one another in such a way that the filter array device can be plugged onto the back of the connector part by the contact pins of the filter array device engaging in the contact sockets of the connection contacts and the ground connector of the filter body touching the housing jacket of the connector, making a ground contact.
  • Such an arrangement has the advantage that a filter array can subsequently be applied to a connector part, be it a socket or a plug, and the filter array can be connected to a line with the contact pins. In this way, it is possible to subject the filter array already connected to a line to a preliminary test before it is brought into contact with the plug or socket housing.
  • the selected arrangement of the filter array device on the connector part allows the entire arrangement to be very space-saving, the diameter being predetermined by the connector part.
  • Another advantage of this arrangement is that with one and the same connector part, the filter arrays can easily be replaced afterwards, without having to replace the entire connector.
  • the contact sockets are arranged at a distance from the rear of the base body of the connector part. In this way, the contact sockets of the connection contacts are well protected against external influences.
  • guide bores are provided in the back of the base body of the plug connector part and aligned with the contact sockets for inserting the contact pins of the filter array device.
  • these guide bores make it easier to attach the filter array device, since the contact pins lead to the Connection sockets are guided in alignment, on the other hand the contact pins are held in the base body at two axially spaced sections, namely once in the contact sockets and the other in the guide bores. This already prevents the filter array from wobbling when plugged into the connector part.
  • the contact sockets are slit in the longitudinal direction, they can resiliently enclose the contact pins of the filter array when the filter array is plugged in, as a result of which good electrical contact is established between the contact sockets and the contact pins.
  • the force-fitting clamping of the contact pins in the contact sockets thereby results in a tight fit of the filter array on the connector part.
  • the connector part can have a housing section which projects beyond the rear of the base body and radially surrounds the housing jacket, forming an annular gap, the ground connector of the filter body having radially elastic spring tongues which, when the filter array device is plugged on, radially outwards against the Press inside of the housing section.
  • the spring tongues located in the plugged-in state of the filter array device in the annular gap between the housing jacket and the housing section are thereby kept in good ground contact with the housing jacket. At the same time, the spring tongues bring about a non-positive holding of the filter array device on the housing of the connector part.
  • the attachment of the filter array to the connector part can be further improved in that the spring tongues have projections projecting radially outwards.
  • the spring tongues have lateral projections and are twisted about their longitudinal axis. In this way, the spring tongues claw with their lateral projections on the one hand on the inside of the housing section and on the other hand on the outside of the housing shell.
  • the outside of the housing jacket in the area of the annular gap can have a roughened surface which interacts with the spring tongues of the ground connector.
  • a positive connection between the lateral projections of the spring tongues twisted about their longitudinal axis and the roughened surface of the housing shell can already be achieved.
  • a deliberate detachment of the filter array device from the housing of the connector part is possible if a corresponding axial force is applied, since the twisted spring tongues are resilient and their projections can thus be brought out of the roughened surface of the housing shell.
  • the spring tongues are radially curved and are supported in the annular gap on the housing section on the one hand and the housing jacket on the other. This results in a non-positive connection between the filter array device and the connector part, the curved spring tongues simultaneously ensuring that the filter body and thus the entire filter array device are centered with respect to the connector part.
  • the plug connector part can be designed as pressure contacts with pressure contacts that yield resiliently in the axial direction be, the pressure contacts in the area of the contact socket being surrounded by a helical compression spring, which are supported on the one hand on a shoulder of the pressure contact and on the other hand on a shoulder in the base body of the connector part.
  • a helical compression spring which are supported on the one hand on a shoulder of the pressure contact and on the other hand on a shoulder in the base body of the connector part.
  • the shoulder in the base body is formed by the area on the rear side of the connector part surrounding the guide bores.
  • FIG. 1 shows an arrangement of a plug connector part, here a plug 1 with pressure contacts 2, and a filter array device 3.
  • the plug 1 has a base body 5 surrounded by a housing jacket 4, in which the pressure contacts 2 are inserted.
  • the pressure contacts 2 protrude to the connection side 6 of the plug 1, to which this is connected to an associated socket.
  • the pressure contacts 2 are arranged axially movably in the base body 5 and are axially resiliently supported by helical compression springs 7. At its rear end facing away from the connection side 6, the pressure contacts 2 each have a contact socket 8 which is open towards the rear 9 of the plug 1.
  • guide bores 10 are provided which are aligned with the contact sockets 8 of the pressure contacts 2.
  • the helical compression springs 7 are supported on a shoulder 11 of the rear side 9 in the region of the guide bores 10.
  • the other end of the helical compression springs is supported on a shoulder 12 of the pressure contacts 2 surrounding the contact sockets 8.
  • the housing shell 4 surrounding the base body 5 has on its outer side 13 located in the area of the rear side 9, behind a flange 14, a surface roughened by circumferential grooves 15.
  • the connector 1 is surrounded behind the flange 14 by a housing section 16 which is sealed off from the flange 14 and the housing jacket 4 by means of an O-ring 17.
  • the housing section 16 is radially spaced from the outside 13 of the housing shell 4, so that an annular gap remains free between the inside of the housing section 16 and the outside 13 of the housing shell 4.
  • the filter array device 3 which is shown particularly well in FIGS. 1 and 3, has a filter body 18 which is penetrated by contact pins 19.
  • the contact pins 19 have in the contact sockets 8 matching contact ends 20 and on the other side of the filter body 18 solder pins 21 for soldering lines.
  • the contact pins 19 are firmly anchored in the filter body 18.
  • the filter body 18 is surrounded by a collar-shaped ground connector 22 or 22 '.
  • the upper half of the filter array device shown in FIGS. 1 and 3 shows the ground connector 22, while the lower half represents the ground connector 22 '.
  • Both ground connectors 22 and 22 ' are collar-shaped and project beyond an end face 23 of the filter body 18 facing the rear side 9.
  • the ground connector 22 is sleeve-shaped and has spring tongues 24 due to axial longitudinal incisions
  • the spring tongues 24 ' are individually embedded in the filter body 18 in the ground connector 22'.
  • the ground connector 22 At its end facing away from the end face 23, the ground connector 22 has a radially inwardly directed edge 25 which engages behind the filter body 18.
  • the ground connector 22 need not be firmly connected to the filter body 18.
  • the spring tongues 24 of the ground connector 22 have at their free ends radially outwardly projecting projections 26 and radially inwardly projecting projections 27.
  • the spring tongues 24 'of the ground connector 22' have lateral teeth 28. As can be seen particularly well from FIG. 3, the spring tongues 24 'are twisted about their longitudinal axis so that the teeth 28 on one side of a spring tongue 24' point slightly radially outwards, while the teeth on the opposite side of a spring tongue 24 ' 28 point slightly radially inwards.
  • Fig. 2 the arrangement according to the invention is shown in the nested state. It can be seen that the filter array device 3 and the plug 1 are matched to one another such that the filter array device 3 can be plugged onto the rear side 9 of the plug 1 by the contact pins 19 engaging with their contact ends 20 through the guide holes 10 in the contact sockets 1 and the ground connector 22 or 22 'of the filter body 18 housing 4 of the plug 1, making a ground contact, touched.
  • the contact pins 19 are mounted with their contact ends on the one hand in the guide holes 10 and on the other hand in the contact sockets 8, which are provided with slots 29 in the longitudinal direction, so that the contact end 20 of a contact pin 19 is clamped by the contact socket 8.
  • the inner projections 27 of the spring tongues 24 engage in the grooves 15 on the housing jacket 4 of the plug 1, as do the teeth 28 in the spring tongues 24 'of the variant of a ground connector 22'.
  • the spring tongues 24 and 24 ' are thus supported on the housing section 16 and on the roughened surface of the housing shell 4.
  • the spring tongues are also radially elastic, so that they can compensate for tolerances and center the filter array device 3 relative to the connector 1.
  • the attachment of the filter array device 3 to the plug 1 is carried out by the spring tongues 24 and 24 'and the contact pins 19 projecting into the contact sockets 8.
  • FIG. 4 shows a further exemplary embodiment of the invention. Identical reference symbols are used for identical or similar components. Only the differences from the exemplary embodiment described above are explained.
  • Fig. 4 consists of a box 30 with fixed pressure contacts 31, which are also inserted into a base body 5.
  • the pressure contacts 31 also have slotted contact sockets 8.
  • the only difference compared to the embodiment shown in FIGS. 1 and 2 is that the pressure contacts 31 do not have springs supported in the base body 8, but are arranged stationary.
  • the filter array device 3 essentially corresponds to that from FIGS. 1 to 3; only the ground connector 22 ′′ is slightly changed. Its spring tongues 24 ′′ are radially curved, so that they are supported in the annular gap on the one hand on the housing section 16 on the other hand on the housing jacket 4. This arched design of the spring tongues 24 ′′ achieves a non-positive connection between the can 30 and the filter array device 3.
  • the box 30 has no rear side with guide bores, so that the contact pins 19 of the filter body 18 are only held in the contact sockets 8 of the box 30.
  • the mode of operation of the arrangement according to the invention according to FIGS. 1 to 3 is described in more detail below.
  • the soldering pins 21 of the filter array device 3 can be soldered to lines which are not shown in detail.
  • the filter array is now connected and can be subjected to a preliminary test before it is inserted into connector 1.
  • the connector 1 itself, as shown in FIG. 2, can already be mounted on a housing section 16 at this time.
  • the arrangement is completed by inserting the filter array device 3 into the rear side 9 of the plug 1 until the end face 23 of the filter array device 3 bears against the rear side 9 of the plug 1.
  • the filter array device 3 can be pulled off the back 9 of the plug 1, the spring tongues 24 and 24 'going out of the grooves 15 due to their spring-elastic effect. In the same way as described above, a new filter array device 3 can now be inserted into the plug from the rear, so that a new filter effect can be achieved without the plug connector having to be exchanged.
  • the mode of operation in the exemplary embodiment shown in FIG. 4 is the same, the filter array device 3 being arranged there only on the can side.
  • the spring tongues 24, 24 'or 24' 'can also engage in the housing shell 4 via a positive locking connection; the grooves 15 would then have to be cut deeper.
