Definitions

  • the invention relates to a plug, in particular for a plug connection for the electrical connection of trailers, with a housing, an inner sleeve, a contact insert fixed to the inner sleeve with contact pins, a bayonet ring for detachable connection of the plug to a socket and one to a rear, the Union nut facing away from the socket, with an externally threaded part of the housing to be screwed on.
  • Such plugs are used for.
  • B. used for the electrical connection of caravans to the towing vehicle.
  • important functional elements such as rear and brake lights, direction indicators, fog lights, etc. of the Trailer powered and controlled by the towing vehicle.
  • the newer 13-pin connection technology enables additional functions. Further current consumers on the trailer can then be supplied with electricity directly from the towing vehicle.
  • a generic connector is known from EP-A 0 249 181.
  • This connector consists of a large number of individual parts.
  • the contact insert with the contact pins is thus fixed between a housing and an inner sleeve by clamping.
  • the housing and the inner sleeve are screwed together, with an O-ring between the housing and inner sleeve to prevent the ingress of dust and moisture.
  • a bayonet ring is pushed onto the inner sleeve, which is axially immovable, but rotatably mounted about the central axis of the plug, by means of a ring bead projection projecting radially outward on a projection of the inner sleeve axially projecting beyond the bayonet ring.
  • the bayonet ring In its rear area, the bayonet ring is formed in a region as a base section, to which a cover support platform is attached.
  • a union nut is screwed onto the rear part of the housing, a seal against the penetration of moisture at the cable entry being provided between the housing and the union nut.
  • a disadvantage of this connector is the relatively large number of its individual components, which not only require a corresponding number of tools for their manufacture, but are also responsible for a corresponding outlay during assembly.
  • the invention has for its object to develop a connector of the type described above in such a way that the smallest possible number of components is required for its provision, so that the manufacturing and assembly work is reduced.
  • the housing, the inner sleeve and the contact insert are designed as a one-piece, continuous molded body, that the molded body has at least one radially outwardly projecting stop arranged in the region of the rear part facing away from the socket end and at least one radially downstream has outside facing, arranged in its central region locking projection, and that the bayonet ring has an inner circumferential groove associated with the locking projection, so that the bayonet ring is held axially with limited play and rotatable about an axis on the molded body.
  • the one-piece design of the housing, inner sleeve and contact insert as a molded body eliminates the need to provide several individual components.
  • the number of individual parts required has been reduced from at least seven to four. Correspondingly fewer molding tools have to be produced, which further reduces the costs.
  • the problem of sealing the housing and inner sleeve against moisture is also avoided. Overall, the assembly of the plug is greatly simplified.
  • the union nut can be assigned to the molded body and can carry a sealing ring. This also represents a further structural simplification of the connector.
  • a cable can be connected to the contact pins using crimping technology.
  • the known crimping technique results in a much better form fit and thus a better contact between the cable and contact pin than the usual screwing of the cable, which could also be solved and a complex disassembly and Repair of the plug conditional or made it completely unusable.
  • a plurality of stops arranged at equal angular intervals can also be provided, or the stop can be designed as a radially circumferential web. In any case, a secure hold of the bayonet ring between the locking projection and the stop is guaranteed. For the same reason, a plurality of latching projections arranged at the same angular intervals can also be provided. It is particularly advantageous if the latching protrusion (s) have bevels. These run-on slopes are arranged rising from the socket side to the rear, so that pushing the bayonet ring onto the molded body is made considerably easier during assembly.
  • the bayonet ring can have an inward-facing, radially circumferential rib on its end facing away from the socket. This rib forms the bearing surface of the rear part of the bayonet ring on the outer jacket of the shaped body, as a result of which a large-area bearing of the bayonet ring on the shaped body is avoided. This reduces the friction when the bayonet ring is rotated relative to the molded body, so that the plug can be operated without any great effort when it is connected to the socket.
  • FIG. 1 the plug is shown in section with the exception of the contact pins.
  • a bayonet ring 3 is a housing 1, an inner sleeve 2 and a contact insert 25, which as one-piece continuous molded body 26 are formed, penetrated.
  • a section 4 of the bayonet ring 3 holds it captively on the molded body 26.
  • an inner radially circumferential groove 5 is provided on the bayonet ring 3 and latching projections 6 and a stop 7 are provided on the molded body 26.
  • the stop 7 is designed as a radially circumferential web.
  • the bayonet ring 3 When assembling the plug, the bayonet ring 3 is pushed in the direction of arrow 8 over the molded body 26 until the locking projections 6 of the molded body 26 snap into the groove 5 of the bayonet ring 3. This is possible due to a certain elasticity of both the bayonet ring 3 and the molded body 26 or the locking projections 6.
  • the stop 7 is arranged at a distance from the locking projections 6, which is matched to the length of the section 4, so that the bayonet ring 3 is held on the inner sleeve 2 with axially limited play in the direction of the axis 9 of the plug.
  • the bayonet ring 3 is, however, rotatably supported about the axis 9 relative to the molded body 26.
  • the bayonet ring 3 can be rotated about an angle of 90 ° with respect to the molded body 26.
  • the angle of rotation is limited in a manner not shown in more detail in that the bayonet ring 3 has a partially annular groove 10, in which a radial projection of the shaped body 26 is guided.
  • the bayonet ring 3 is used to connect to a socket which has corresponding projections for engaging in the bayonet grooves 11.
  • the front one Part of the bayonet ring 3 encloses the inner sleeve 2, which is designed as a hollow cylinder and forms the receiving space for the contact pins.
  • a rib 24 (see FIG.
  • the socket has a corresponding groove suitable for receiving the rib 24.
  • the outer circumferential surface of the inner sleeve 2 is smooth-walled except for the radial projection which is guided in the groove 10. This makes it easier the sliding of the bayonet ring 3 onto the molded body 26.
  • a front end region 12 protrudes from the bayonet ring 3 on the socket side, which facilitates the attachment of the plug to the socket.
  • the rear end of the molded body 26 is provided with an external thread 14, onto which a union nut 16 provided with an internal thread 15 is screwed.
  • the union nut 16 has an opening 17 which is used to feed a cable.
  • a sealing ring 18 is provided, which seals the interior 19 of the connector against moisture, dust, etc.
  • the sealing ring 18 is partially pressed radially inward by an inner bead 27 in the end region of the molded body 26, and is thus pressed sealingly against the cable.
  • Part of the bayonet ring 3 is also a base 20, on which a lid support platform, which is not shown here, is attached.
  • the lid support platform can be rotated with the bayonet ring 3 relative to the shaped body 26 and is arranged such that when the plug is inserted into the socket, the lid provided on the socket comes to rest on the lid support platform.
  • the bayonet ring 3 has an inwardly facing, radially circumferential rib 21 at its rear end.
  • the rib 21 comes into contact with the outer lateral surface of the molded body 26, so that a gap 22 is formed between the molded body 26 and the bayonet ring 3 and a flat contact between the inner surface of the section 4 of the bayonet ring 3 and the outer lateral surface of the molded body 26 is avoided becomes. This reduces the friction between the two parts, which contributes to easier operation when the bayonet ring 3 is rotated relative to the molded body 26.
  • FIG. 2 shows a front view of the molded body 26 with the contact insert 25 in the assembled state.
  • the contact pins 23 and the arrangement of the axial rib 24 with respect to the Contact pins 23 can be seen in the inner sleeve 2.
  • a total of 13 contact pins 23 are provided, so that compared to the old standard, in which only seven contact pins were provided, the power supply is provided for further functions.
