Definitions

the invention relates to a socket for a plug connection for the electrical connection of motor vehicle trailers, with a closing under the action of a spring, sealingly abutting a housing.
Such a socket is known for example from DE-G 86 14 311. Since such sockets are attached to motor vehicle bodies, they are exposed to all environmental influences, in particular the rain. To prevent the contact pins in the socket from becoming dirty or corroding, the cover of the socket is pressed against the socket housing under the action of a spring. A seal between the socket cover and the socket housing ensures that no liquid or dirt can enter.
one leg of a leg spring rests in a recess on the outside of the cover.
the recess together with the spring leg accommodated therein is covered by a snap-in cover plate.
a disadvantage of such a socket is that if the cover plate falls off or is destroyed, the spring is exposed.
the cover plate which consists of a relatively thin plastic part, can easily be destroyed, for example, in a rear-end collision or by careless handling of devices. The exposed spring is then exposed to increased corrosion and damage.
the object of the present invention is therefore to improve a socket of the type mentioned in such a way that the spring pressing the cover is protected.
the object is achieved in that one leg of the spring rests against the inside of the cover and is connected to it, and in that the inside, together with the spring leg, is covered with a seal.
the spring rests on the inside of the cover, it is protected from the outside by the entire cover from damaging influences. Furthermore, it is completely covered on the inside by the seal, thus also protected from this side.
This arrangement also has the additional advantage that, if the outside of the cover is pressed very hard, for example in the event of a rear-end collision, a considerable proportion of the forces which occur are absorbed by the work of deformation of the elastic seal arranged on the inside. This means that, in contrast to the lid construction of the type mentioned at the outset, the spring towards the outside is already covered by a much thicker material and, moreover, is much better able to withstand shock-like loads due to the elasticity of the seal.
an eyelet is provided on the inside of the cover, into which the leg can be inserted.
the advantages mentioned above are further enhanced by the fact that the eyelet is arranged approximately centrally in the middle of the inside of the cover.
a disc-shaped seal is provided, which is flat on one outer side facing the housing and on the other inner side is provided with annular bead-like projections which have corresponding annular bead-like projections on the inside of the Hold the lid in place.
the seal has, on the outer side, concentrically arranged, annular sealing lips which lie sealingly on the upper ring edge of the housing when the cover is closed.
the sealing lips on the one hand provide an excellent sealing seal between the cover and the housing and on the other hand promote the buffer or shock absorption effect mentioned above, so that the spring is then particularly well protected.
a plurality of openings are provided circumferentially between the seal and the edge of the cover, so that rain or condensation water which has accumulated between the inside of the cover and the seal can escape in any mounting position of the socket.
the seal has on the outer side a plurality of radial locking lips distributed around the circumference, which intersect the annular sealing lips.
a socket 10 shown in FIG. 1 is mounted on an outer wall of a motor vehicle 12.
the socket 10 has a housing 14 and a cover 16.
the housing 14 is firmly connected to the motor vehicle 12 by screws 18, 18 '.
the housing 14 is mounted in such a way that a hinge 20 of the cover 16 comes to rest at the upper end.
the cover 16 has two side parts 22, 24 in the area of the hinge 20 (see FIG. 2), which can be inserted between corresponding areas of the housing 14.
the connection between cover 16 and housing 14 in hinge 20 is made via a bolt 32.
a leg spring 26 is wound around the bolt 32 in a torsion-like manner between the two side parts 22, 24, one leg 28 of which abuts against the inside 34 of the cover 16, whereas the other leg 30 is directed downward in the direction of the housing 14 and is received by the latter.
the leg 28 extends along a diameter of the roughly circular contour of the cover 16 into the cover and protrudes beyond the center of the circle.
An eyelet 36 is arranged approximately centrally in the middle on the inside 34 of the cover 16, which is formed in one piece with the cover 16 and protrudes therefrom.
the eyelet 36 has an opening 38 through which the leg 28 of the leg spring 26 is pushed.
the diameter of the opening 38 corresponds approximately to the diameter of the leg 28 so that it can slide back and forth in the opening 38 when the lid is opened and closed.
the inside 34 of the cover 16 is covered with a disk-shaped seal 40.
the seal 40 covers the entire leg 28, which emerges in the area of the hinge 20 between the seal 40 and the cover 16 and merges into the torsionally wound coil on the bolt 32.
the seal 40 has on its inner side 44, which faces the inside 34 of the cover 16, three concentrically arranged annular bead-shaped projections 46, 48, 50 which are inserted in a clamping manner between two, likewise concentrically arranged ring flanges on the inside 34 of the cover 16 . As a result, the seal 40 is held firmly on the inside of the cover 16, but can be removed if desired.
the seal 40 On the outer side 42, the seal 40 is provided with concentric annular sealing lips 56, 56 ', 56 ⁇ (see FIGS. 2 and 3), via which the seal 40 rests on the annular upper edge of the housing 14. Furthermore, radial locking lips 70, 70 ', 70 ⁇ ... are provided (here: eight locking lips each offset by 45 °), which prevent liquid from migrating spirally towards the center of the cover if the cover 16 does not lie coaxially on the edge of the housing.
the seal 40 seals almost the entire space between the inside 34 of the cover 16 and the outer ring flange 54 of the cover. However, it is possible that moisture can penetrate in the area of the hinge 20, at the point at which the leg 28 enters this space between the inside 34 of the lid and the seal 40.
openings 74, 74 ', 74 ⁇ and 62 are provided circumferentially around the lid edge between the seal 40 and the lid edge.
the opening 62 in the area of the handle tab 64 of the lid is formed over the entire length of the handle tab 64, since if the socket 10 is mounted as shown in FIG. 1, a main flow direction of the hinge 20 towards the handle tab 64, as is shown by the Arrows 66, 68 and 68 'is shown, is present.
the circumferential openings 74, 74 ', 74 ⁇ ensure, however, that if the socket is offset at an angle to the manner shown in Fig. 1, liquid can also escape from the lid.
openings 74, 74 ', 74 ⁇ are shown. However, several, successive openings 74, 74 ', 74 ⁇ ... separated by webs 76 can be provided.
the socket i.e. Housing and lid are made of common injection molding materials
the seal 40 consists of a weather-resistant elastomer.
