Definitions

  • the invention relates to a connector, in particular a connector with high electrical insulation, suitable for industrial use in harsh environmental conditions. It has a male plug part and a female coupling part, wherein the male plug part is provided with a latching cam on the peripheral surface and in the jacket of the female coupling part a latching groove for producing a bayonet connector is provided.
  • Connectors are used in many areas of electrical engineering, such as industrial multi-channel measuring technology. They have to meet different application criteria.
  • BNC plugs have much larger dimensions. They are suitable for laboratory applications. Such a BNC plug for radio frequency applications is shown in US-A-2003/0129870, which additionally has a bayonet closure. A plug part with locking groove is additionally provided with a rotatable knurled ring, which complicates the structure and increases the dimensions.
  • the invention is therefore the object of further developing existing connectors so that a mechanically stable and sealed plug connection can be reached, which also allows a quick and easy connection and disconnection even under harsh environmental conditions. In addition, a high electrical insulation for piezoelectric applications should be ensured. The connection should also be easily and quickly checked.
  • the object is achieved by a connector with the features of claim 1.
  • the inventive connector has a male connector part with a locking cam and a female coupling part with a locking groove. According to the invention, either the male plug part is mounted in advance on the circumference and the latching cam or a sealing ring is arranged on the inner circumference of the female coupling part of the latching cam. When the plug connection is closed, the sealing ring lies sealingly between the inner circumference of the female coupling part and the circumference of the male plug part.
  • the sealing ring thus seals radially between the male connector part and the female coupling part. Regardless of the depth of connection of the two parts of the connector to each other, the sealing ring is never crushed axially, since it rests only radially. This is important because the sealing ring is not subjected to the vibration vibrations of the coupling parts in this arrangement, so that its elastic property is not disturbed by vibrations. In addition, so-called triboelectric signal interference can occur by rubbing contacts in one movement and thereby generate electrical charge. This effect is extremely disturbing, especially in piezoelectric applications.
  • the plug resp. Clutch parts mechanically robust, tight and can be connected while maintaining existing dimensions of the plug.
  • Such bayonet locks are suitable as a plug connection for electrical connectors under harsh environmental conditions, up to 150 ° C ambient temperature, while ensuring a high electrical insulation.
  • Advantageous embodiments are disclosed in the dependent claims.
  • the sealing ring is preferably an O-ring, in particular of temperature-resistant EPDM.
  • the male connector part is provided with a sealing ring on the circumference and the locking cam upstream, whose outer diameter is adapted to the inner diameter of the female coupling part.
  • the female coupling part may in particular have an internal compression spring.
  • the bayonet connector according to the invention allows a quick and safe loosening and connecting, since on the one hand only a rotational movement of about 90 ° is executed and on the other hand, the locking cam at the end of the rotational movement in a staggered terminal of the locking groove snaps, allowing a clear, secure closure state.
  • connection and disconnection is also possible in confined spaces uncomplicated.
  • connection is also due to the integrated seal by means of sealing dustproof and waterproof IP 67 IP.
  • inventive connector also allows the solution of a subtask, which is to allow the compact arrangement of many such connectors.
  • connection plate is preferably received in a flange of a central circular connector, while the female coupling parts are routed through a ring plug.
  • the male connector parts are fixable on a, preferably detachable connection plate of the flange.
  • FIG. 2 shows a bayonet connection according to the invention of the plug parts of FIG. 1, FIG.
  • FIG. 3 shows a summing box for a multiple arrangement of bayonet connections according to FIG. 2. Ways to carry out the invention
  • Fig. 1 shows a male connector part 1 and a female coupling part 2 for producing a bayonet connection with little effort, which can also avoid accidental release of the connection.
  • a jacket 22 of the female coupling part 2 is provided with a curved, preferably i ⁇ shaped locking groove 4 and the male connector part 1 with a corresponding locking cam 3.
  • the locking cam 3 is mounted a groove in which an elastic sealing ring 5, for example in shape an O-ring made of temperature-resistant EPDM.
  • the locking cam 3 on the male connector part 1 corresponds to the locking groove 4 on the female coupling part 2.
  • a compression spring 6 is provided in the jacket 22 of the female coupling part 2.
  • the locking groove 4 has a vorvermine terminal 18 (FIG.
  • the connector preferably has a diameter of at most 6 mm.
  • a pin 9 in the female coupling part 2 is connected to a low-noise cable 7 with built-in strain relief 21.
  • a seal between the cable 7 and coupling part 2 is given.
  • a corresponding seal can also be provided on the plug part 1.
  • the force of the compression spring 6 can be freely designed without having an influence on the sealing properties of the sealing ring 5.
  • the connector is electrically highly insulated with an insulation of at least 10 12 ohms.
  • the connection between the coupling part 2 and the cable 7 is also sealed.
  • a use of the connector at high ambient temperatures is guaranteed because all components used, in particular the sealing ring 5, can carry at least 150 ° C, which can be done by selecting suitable materials and dimensions.
  • FIG. 3 shows a further illustration of a summing box for a compact arrangement of many plugs of a multi-channel system, for example for flatness measurements in machines or installations.
  • male connector parts 1 are fixed on a connection plate 14.
  • the female coupling parts 2, shown only in broken lines in FIG. 3, and the associated cables 7, which are merely indicated, are formed by bores 16, which are provided peripherally in a receiving part 15 of a ring. attached pot 20 are pulled through and led to the male connector parts 1.
  • connection plate 14 Before or after production of the inventive bayonet connectors, the connection plate 14 is connected to a flange 11 of a multi-pole circular connector 10. On the peripheral surface of the flange 11, in turn, a groove for a further O-ring 12 is provided, for the purpose of tight arrangement in a base, not shown.
  • the connection plate 14 is seated on a sealing and compensation ring 13 on the flange 11.
  • Another advantage of the arrangement according to the invention is that it can be quickly checked at any time whether each connection is properly closed or not, since the locking cams 3 are visible from the outside. If you are sitting in the locking groove 4, the connection is correct.
  • a ent ⁇ speaking alignment and arrangement of the bayonet connectors on a connecting plate 14, which allows a visual inspection of each individual connection is thus desirable.
