Definitions

  • the invention relates to a connector part that can be attached to a device wall, such as a plug or socket, with a base body in which there are provided connecting contacts that extend to a connection side and are connected at their rear end facing away from the connection side to a filter array device Housing which has a housing jacket surrounding the base body and in the installed state of the connector part penetrating an opening in the device wall and a mounting flange which can be fastened to the device wall, and having a mass spring ring which at least partially surrounds the housing jacket and which in the installed state of the connector part has the filter array device, the housing jacket and the mounting flange, making a ground contact.
  • a device wall such as a plug or socket
  • a connector part of the type mentioned is known.
  • the mass spring ring penetrates the connector there as a plate-shaped part and extends below the mounting flange.
  • convex spring tongues are provided, which make the ground contact between the opening edge of the device wall and manufacture the housing jacket. Housing shell and mounting flange are in one piece in the known connector part.
  • the housing is formed in two parts with the mounting flange and the housing jacket as a separate part in each case, that the mounting flange has an insertion opening adapted to the outer periphery of the housing jacket, in which an inwardly projecting annular shoulder is arranged, and that on the at the rear end of the housing jacket there is an outwardly projecting stop shoulder which is adapted to the annular shoulder in the insertion opening and which has an end face facing the annular shoulder, up to which the mass spring ring extends, with an external thread being applied to the housing shell in the direction of insertion in front of the stop shoulder, which matches the internal thread of a fastening nut which is supported relative to the mounting flange.
  • connection contacts provided in the base body surrounded by the housing jacket to be wired at their rear end, while the base body of the connector part is located inside the device.
  • the base body enclosed by the housing jacket is then inserted from the inside into the rear of the device wall and the opening into the mounting flange until the spring washer abuts the end face of the ring shoulder facing the stop shoulder.
  • the mass spring ring already touches the opening edge of the device wall or the mounting flange. Due to the mounting nut that can be screwed onto the housing jacket from the front of the device wall, the mounting flange and the housing jacket are braced against each other, which ensures good mass contact between all parts.
  • Another advantage of the connector part according to the invention is that it can now be hermetically sealed against the device wall.
  • the end face of the stop shoulder of the housing jacket can be beveled in the shape of a truncated cone in the direction of insertion, the opposite end face of the annular shoulder of the mounting flange can be beveled accordingly.
  • this has the advantage that the Housing shell and the spring washer are centered opposite the mounting flange.
  • the bevel also acts as an insertion bevel if the housing part is pushed into the opening of the device wall from the rear. This is particularly important when you consider that the view of the opening in the device wall is mostly obscured by circuit boards or the like attached to the rear of the connector part.
  • the mass spring ring consists of essentially axially extending spring lamellae, which are connected tangentially to one another via transverse webs, the spring lamellae in the region of the outer circumference of the stop shoulder being bent radially outward in a convex manner toward the opening edge of the device plate, and the free front ones in the insertion direction Grip the ends of the spring slats radially inwards over the end face of the stop shoulder.
  • This ground contact can be produced particularly easily if the filter array device is designed as a filter disk which is penetrated by the rear ends of the connection contacts and if the U-shaped bent free ends of the spring blades press against the outer edge of the filter disk.
  • the filter array device does not need to be soldered to the mass spring ring, which considerably simplifies the assembly of the connector parts. In addition, it is easily possible to replace the filter disk with another filter disk.
  • an open groove is formed in the installed state to the inner wall of the annular shoulder, in which a sealing ring is inserted.
  • a hermetic seal of the mounting flange with respect to the device wall can also be achieved, without the good ground contact between the connector part and the device wall suffering from this.
  • the connector part In connection with the seal between the housing jacket and the mounting flange, the connector part is thus hermetically sealed against the housing wall.
  • a smooth front in the installed state of the connector part can be achieved in a simple manner if the annular shoulder delimits a recess for the fastening nut which is open to the front of the mounting flange. In the installed state of the connector part, the fastening nut is then in this recess.
  • At least one recess or a projection is formed as a means of preventing rotation between the mounting flange and the housing jacket on the end face of the stop shoulder, into which a corresponding projection or a recess of the annular shoulder engages. This provides a structurally particularly simple anti-rotation device.
  • the connector part is to be attached to thin housing walls, it is expedient if an apron, which extends essentially parallel and at a distance from the housing jacket, is attached, on the inside of which, when the connector part is installed, the convex spring lamellae of the spring washer are bent.
  • the spring slats are no longer supported on the opening edge of the device wall, but on the inside of the apron.
  • the mounting flange can also be attached to the device wall from the rear.
  • a wall 1 of a device is shown in sections.
  • the housing wall 1 it can be, for. B. act on the front panel of a device.
  • connection contacts 5 extending to the connection side 4 of the socket 2 are provided.
  • connection contacts 5 are connected to a filter disk 6 as a filter array device. More specifically, the filter disk 6 has openings through which the pin-shaped ends of the connecting contacts 5 pass.
  • the outside of the filter disk 6 is surrounded by a metal layer 7.
  • a printed circuit board 8 is soldered behind the filter disk 6 to the pin-shaped ends of the connection contacts 5, via which the connection contacts 5 are wired with cables, not shown.
  • the socket 2 also has a two-part housing, which consists on the one hand of a housing jacket 9 surrounding the base body 3 and on the other hand of a mounting flange 10.
  • the housing jacket 9 passes through an opening 11 in the wall 1, while the mounting flange 10 is screwed on from the front of the wall 1.
  • the screws are not shown.
  • the opening 11 in the wall 1 is step-shaped.
  • the mounting flange 10 is also stepped in the region of the opening 11 and has a cylindrical part projecting approximately into the half opening 11, in which a radially inwardly directed annular shoulder 12 is formed.
  • the annular shoulder 12 is offset towards the front of the mounting flange 10 and thus delimits a recess 13 that is open toward the front of the mounting flange 10.
  • a circumferential recess is provided on the outside of the cylindrical part, in which a sealing ring 14 is inserted. The sealing ring 14 seals the mounting flange 10 against the wall 1.
  • the end face 15 of the annular shoulder 12 directed towards the rear of the wall 1 is beveled in a funnel shape. At some points on the end face 15, projections 16 directed axially to the rear of the wall 1 are provided.
  • annular shoulder 12 also projects radially inwards with respect to the edge of the opening 11.
  • the housing jacket 9 is equipped at its rear end with a radially outwardly projecting stop shoulder 17.
  • the stop shoulder 17 extends approximately over the last quarter of the total length of the housing jacket 9 and surrounds the filter disk 6 at a distance.
  • the housing jacket 9 can thus be seen from the rear of the wall 1 in Direction of arrow E are inserted into the mounting flange 10.
  • the front end face 18 in the insertion direction E is beveled in the shape of a truncated cone, the degree of obliqueness being matched to that of the end face 15 of the annular shoulder 12.
  • recesses 19 are provided in the stop shoulder 17, into which the projections 16 of the annular shoulder 12 engage in the installed state as an anti-rotation device.
  • a radially open circumferential groove 20, which receives a sealing ring 21, is incorporated in the housing jacket 9.
  • an external thread 22 is applied on the outside of the housing shell 9.
  • the housing jacket 9 is surrounded in the area of the stop shoulder 17 by a mass spring ring 24 which, when the socket 2 is installed (see FIG. 1), making a ground contact, the filter disk 6, the housing jacket 9, the mounting flange 10 and the edge of the opening 11 touched.
  • the area of the mass spring ring 24 surrounding the outer wall of the stop shoulder 17 is barrel-shaped with individual radially outwardly convex and axially extending spring plates 25, which at the points where they rest on the outside of the stop shoulder 17, by tangential transverse webs 26 are connected.
  • the spring lamellae 25 each have free ends 27 and 28 which extend beyond the transverse webs 26.
  • the front free ends 27 in the insertion direction E are bent in the shape of a truncated cone radially inwards in accordance with the slope of the end face 18 of the stop shoulder 17 and overlap the end face 18.
  • the rear free ends 28 in the insertion direction E are bent inward in a U-shape and press resiliently against the outer metal layer 7 of the filter disk 6. Individual rear free ends are not bent, but project axially to the rear and are soldered to the circuit board 8 with ground contacts.
  • the base body 3 surrounded by the housing jacket 9 is located inside the device or on the back of the device wall 1. In this state, the rear ends of the connecting contacts 9 or the printed circuit board 8 can be wired take place without any cables having to be pulled through the opening 11 of the wall 1.
  • the mounting flange 10 is first screwed onto the wall 1 from the front (see FIG. 2).
  • the mounting flange 10 is already sealed off from the wall 1 by the sealing ring 14.
  • the rest of the socket 2 is inserted into the opening 11 from the rear of the wall 1 in the insertion direction E. Since the front free ends 27 of the mass spring ring 24 are tapered in the shape of a truncated cone, they act as an insertion bevel and facilitate insertion, even if the view of the opening 11 is covered by the printed circuit board 8.
  • the spring blades 25 When inserted, the spring blades 25 are slightly compressed radially inwards, whereby the front free ends 27 lift slightly from the end face 18 of the stop shoulder 17, while the rear free ends 28 are pressed increasingly against the metal layer 7 of the filter disk 6.
  • the projections 16 of the annular shoulder 12 engage in the recesses 19 of the stop shoulder 17, the projections 16 reaching between two adjacent front free ends 27.
  • the fastening nut 23 is placed over the housing jacket 9 from the front of the wall 1 and brought into engagement with the external thread 22.
  • the housing jacket 9 is pulled further against the mounting flange 10, as a result of which the front free ends 27 of the mass spring ring 24 are clamped between the two end faces 15 and 18 of the annular shoulder 12 in the stop shoulder 17.
  • This pressure acting on the front free ends causes the spring blades 25 to be pressed increasingly against the edge of the opening 11.
  • the socket 2 is now in the installed state shown in FIG. 1.
  • all housing parts and the filter disk are connected directly to the mass spring ring 24, so that a very good equipotential bonding is produced between these parts.
  • the housing jacket 9 is hermetically sealed against the mounting flange 10 and the sealing ring 14 against the wall 1 via the sealing ring 21.
  • FIG. 3 shows a variant of the connector part described above, the structure and function of which are basically the same. Identical reference numerals are therefore used for identical and similar components.
  • the mounting flange 10 is screwed onto the device wall 1 from the rear.
  • the mounting flange 10 has an apron 29 which surrounds the housing jacket 9 and on which the spring plates 25 of the mass spring ring 24 are supported. So the mounting flange for attaching the Connector part also serve on very thin device walls. Except for the mounting flange, both embodiments of the connector part described are the same.
