Definitions

  • the invention relates to a plug for a plug connection for the electrical connection of motor vehicle trailers, with a plug housing which is provided on its approximately cylindrical outside with a radially projecting projection on which a disc-shaped cover plate is received, the cover plate serving as a support for a socket cover .
  • Such plugs are used to establish an electrical connection between a motor vehicle and a trailer. In this way, for example, taillights, brake lights or the like of the trailer are to be supplied with current.
  • a power-supplying socket is provided on the rear of the motor vehicle, usually in the area below the bumper, while the plug is arranged on the trailer.
  • the connector housing is provided at the front end, which is to be inserted into the socket, with a bayonet connection part which is attached to a corresponding bayonet guide in the socket for inserting the plug into the socket.
  • the bayonet connection part of the plug is rotatably seated on an inner sleeve of the plug, in which a contact carrier carrying the contacts is received.
  • the inner sleeve including the contact carrier moves in a linear movement into the socket body, whereas the housing, together with the cover plate received on the radially projecting attachment, moves in a helical motion around the inner sleeve received in the socket in a rotationally fixed manner.
  • the swivel angle of the relative movement between the inner sleeve and the bayonet connector is usually 90 °. In the two end positions of the relative rotational position of the inner sleeve and the bayonet connector, these are locked together and can only be rotated against one another by overcoming a certain locking force or by releasing a lock.
  • the cover plate comes to rest in such a way that the socket cover comes to rest with its inside on the upper surface of the cover plate.
  • the cover plate is designed as a disc-shaped injection molded part, the outside of which is provided with cast-on manufacturer, distributor or vehicle manufacturer emblems. This means that a respective label can be attached inexpensively by equipping it with different cover plates.
  • the plug When the plug is pushed in, the self-closing cover of the socket is lifted with one hand against the force of a closing spring, and the plug gripped with the other hand is turned accordingly.
  • the connector is gripped by the hand so that it engages around the cover plate and the connector housing.
  • a disadvantage of such known plugs is that the disk-shaped cover plate in the case of the firm grip required to turn a plug attached to a socket during the insertion movement into the socket with its relatively narrow circumferential outer edge presses into the inside of the hand which grips it, which is at least disturbing is felt and can also cause injuries to the palm of sensitive people. It is also possible that when gripping the plug vigorously and rotating it, fingers are delimited into the roughly U-shaped space below the cover plate, which is delimited by the underside of the cover plate which extends beyond the attachment, the attachment itself and the outside of the connector housing correspondingly below the cover surface. be pushed in or squeezed in, which is also extremely uncomfortable and associated with pain in sensitive people. Therefore, such plugs are not firmly held by such people, which affects the safe handling.
  • the object of the present invention is to remedy this situation and to improve a plug in a simple manner in such a way that it can be handled safely and is pleasant to hold in the hand.
  • the object is achieved in that in the space below the cover plate is provided on a panel arranged between the edge of the cover plate and the plug housing, through which the space is at least partially filled.
  • the cover which may also be retrofitted, ensures in a simple manner that the sharply contoured transition from the underside of the cover towards the plug housing is eliminated, ie a person who grips the plug by hand no longer has the feeling that a thin-surface, cutting-like Press part into the palm. Furthermore, it can be excluded by the cladding that fingers can be squeezed into the room.
  • the cladding can be designed in such a way that fingers or fingertips of a human hand can be placed on the cladding in a manner that is easy to grip.
  • the sharp and angular contouring in the roughly U-shaped area between the underside of the cover plate and the outside of the connector housing is no longer available and has been replaced by the provision of the cladding in a contour that is more suitable for gripping by hand.
  • a massive block is created in the area of the cover plate can be gripped comfortably and at the same time firmly by a human hand, so that not only is an annoying or uncomfortable feeling eliminated, but at the same time the effect is achieved that the plug can be gripped much more reliably.
  • the covering is molded in one piece with the cover plate on its underside.
  • This measure has the advantage that the cladding is very easy to manufacture in terms of production technology and that plugs already in use can be converted into the more user-friendly and safe configuration by replacing the cover plate.
  • This measure also has the additional advantage that the cover plate is stiffened as such, so that the risk of damage is reduced. It has been found that, in practical use, after the plug has been removed from the socket, it is often dropped carelessly onto the floor, since attempts are being made at the same time to uncouple the trailer from the car. If the plug is dropped on a hard surface, it can be damaged if it hits the surface with the edge of the cover plate. The stiffening cladding counteracts this.
  • the cladding can expediently already be molded onto the base.
  • the cladding can be formed in one piece with the plug housing and extend so far into the housing as far as the underside of the cover plate that the cover serves as a lug supporting the cover plate.
  • the cladding extends from the edge of the cover plate in a straight line, convex, concave or straight line with indentations to the connector housing.
  • the cladding is provided only in the area below the cover plate, which projects laterally beyond the shoulder.
  • This measure has the advantage that a covering is provided only in the areas which come into contact with the hand when a plug is normally gripped. This measure is particularly economical and leads to material savings and thus weight savings for the entire connector.
  • a first exemplary embodiment of a plug 10 according to the invention shown in FIGS. 1 to 8 has a plug housing 12, the outer side 13 of which is provided with a shoulder 30 on which a cover plate 32 is received.
  • the plug housing 12 At its front end, via which the plug 10 is to be inserted into a socket, the plug housing 12 has a bayonet connection part 14.
  • the bayonet connector 14 is provided on its outside with a plurality of serpentine recesses 15, in which engage corresponding projections on the inside of the socket, which then a rotation, for example by 90 °, the connector housing 12 together with the bayonet connector 14 is forced.
  • the cover plate 32 is pivoted clockwise by 90 ° before being plugged into the socket.
  • An inner sleeve 16 is accommodated in the plug housing 12, which is accommodated in a suitable manner, but can be rotated by 90 ° relative to the plug housing 12.
  • the maximum rotational movement in both directions is limited here by end stops, not shown, and the inner sleeve 16 and connector housing 12 are detachably locked together in the end positions.
  • the inner sleeve 16 projects beyond the bayonet connection part 14 at the front end in a larger diameter area and also lies against a shoulder on the inside of the connector housing 12, so that the inner sleeve 16, which is inserted into the connector housing 12 by pressing, is axially immovably received in the latter.
  • a contact carrier 18 is received, which carries contacts 20 which are connected to conductors 22.
  • the conductors 20 are combined into a bundle and emerge from the plug 10 through a spout 24.
  • the contact carrier 18 is equipped with 13 contacts 20 (see in particular Fig. 1).
  • a rib 17 is provided which, when attached to a socket with a corresponding recess on the socket body, comes into positive engagement, as a result of which the inner sleeve 16 together with the contact carrier 18 is inserted non-rotatably into the socket, whereas the bayonet connection part 14 rotates by 90 ° around the inner sleeve 16.
  • an intermediate piece 26 is provided, which is screwed or locked to the inside of the plug housing 12 or to the inside of the inner sleeve 16.
  • a screw cap 28 forms an end closure of the plug housing 12 and also serves to axially fix the spout 24.
  • the radially protruding projection 30 from the outside 13 of the connector housing 12 has two sled shoes 52, 52 ', in the corresponding T-rails 42, 42', which on the underside 34 of the cover plate 32nd are arranged (see in particular Fig. 5) can be inserted.
  • a recess 47 is provided on the outside 13 of the connector housing, between the sled shoes 52, 52 '.
  • the connector housing 12 including extension 30 and the cover plate 32 are made of injection molding materials.
  • a panel 36 is provided on the underside 34 of the cover plate 32.
  • the cladding 36 consists of two lugs 38, 38 'formed in one piece with the cover plate 32, which, starting from the cover plate peripheral edge 33 away from the cover plate underside 34 and viewed in the radial direction of the cover plate surface, at a distance from the T-rails 42, 42' extend.
  • Each attachment 38 or 38 ' which are arranged identically and in mirror image to a diameter of the circular cover plate underside 34, extends away from the cover plate peripheral edge 33 and viewed in the direction of the underside center, in a gentle curve 40 or 40' (see in particular Fig. 5) .
  • the cover plate 32 is thus provided on its underside 34 with a gently rounded material thickening, which ensures that on the one hand the cover plate is stabilized and can also be gripped from the side without sharp indentations in the hand.
  • each extension 38, 38 ' (see in particular Fig. 4) runs out in a gentle curve 48.
  • the cladding 56 consists of two lateral shoulders 57, 57 'on the underside of the cover plate 32 in the same way as previously described in connection with Figs.
  • Each approach 57, 57 ' ends in the immediate vicinity in front of the outside 13 of the connector housing of the connector 10', so that almost the entire space below and to the side next to the approach 30 is filled. This creates a massive but lightweight block that can be gripped particularly securely and firmly.
  • a particularly ergonomically designed outer contour is created, which leads to a particularly user-friendly plug 10 ⁇ .
  • the projection 75 which projects radially from the plug housing and which is formed in one piece therewith, is shaped such that when the cover plate 32 is pushed on, the space below the cover plate 32 and the outside of the plug is filled in, so that a covering 76 is thereby formed.
  • the approach 75 is, as described above, of course provided with sled shoes for pushing on the cover plate 32.
  • the cover 76 or the extension 75 runs in a straight line on the front transverse edge in the transition area to the bayonet connection part 14, so that, as can be seen in FIG. 11, the cover plate 32 projects beyond this area. In the lateral area, however, the cladding 76 extends right up to the underside and the outer peripheral edge 33 of the cover plate 32.
  • a depression 78 or 78 ' is provided on each side, to which fingers of one hand can be placed.
  • the extension 30 is provided with lateral extensions 87, 87 ', which form the panel 86.
  • each approach 87 or 87 'laterally jumps so far that it reaches a vertical line of alignment of the peripheral edge 33 of the cover plate 32.
  • cap-shaped extension 87 a roughly triangular space is again left free, can be inserted into the fingers of one hand in order to securely grip the plug 10 ⁇ ⁇ .
