Waterproof socket with lid. - Vattentät stickkontakt med lock.

The invention relates to a waterproof socket as set out in the preamble of claim 1.

Plug-in switches are divided into splash-proof and watertight protection against moisture. When the plug is not in place, the required splash protection of the sockets and switches must be achieved by means of a cover that is securely connected to the appliance. For waterproof models, there is a standardized rotary switch method (bayonet method) that facilitates use, especially in difficult operating conditions. The previous dimensioning for two-pole sockets with protective contact has been retained in DIN 49442.

Other hinged covers, which are attached to the socket with a hinge to protect against dust and splashing water, are not suitable for watertight types, as the bayonet system can only be locked by turning the cover. To prevent the screw cap designed for bayonet mounting from disappearing, it is usually connected to the socket with a chain. However, such a chain connection is not only quite insecure because the chain can tear, but also detrimental because the cover may hang exactly where it prevents other devices or fasteners from being connected.

Mennecken's "Partner fur Sicherheit" catalog 1980 describes on page 4 a watertight plug switch in which the hinged cover closes the socket watertight. Here, the standard is operated with a bayonet switch comprising a bayonet flange attached to the socket and a handle attached to the cover placed on the lowered cover. The cover is therefore substantially similar in design to other reversible covers used in sockets, with the difference that the bracket enables a bayonet connection. The bracket is a relatively large, strong part that extends far over the surface of the cover, which in itself is not more disturbing as it is a question of large CEE rotary plug connectors for industrial use.

The object of the invention is to provide a waterproof socket as mentioned in the preamble of claim 1, the cover of which can be opened by turning the bayonet switch, as shown in particular in DIN 49442, without the need for a bracket which considerably increases the height of the socket and complicates design. However, the cover must be connected to the socket with a hinge so that it cannot be lost.

This task is solved as described in the characterizing part of claim 1. Other embodiments and further developments of the invention are mentioned in the subclaims.

The invention solves the set task in a surprisingly simple way. The cover is an unchanged screw cover with a basic structure suitable for Bajo net mounting. The rotatability of the cover required for the rotational movement is guaranteed by suitably shaping the connecting part connecting the cover to the hinge flap extending over it. The cover can thus be separated from the socket at any time when the socket is used, but it remains connected to the socket via a hinge flap so that it cannot be lost.

The connecting part can be quite different in a further embodiment of the invention. A pin rotatably mounted in the middle of the lid could thus act as a connecting part and, on the other hand, guarantee rotatability when it engages a recess in a part or a hole to which it is not uniformly attached. Holes in the cover or hinge flap are simpler to use for positioning than corresponding recesses. Admittedly, the holes must not ruin the design and, in particular, must not create a leaky cover.

In a suitable embodiment, two hooks are formed in the hinge flap, which engage two symmetrically opposite grooved openings in the cover. Locking lugs are formed in the hooks which hold the lid to the hinge flap.

It is further provided that the grooves of the lid are arranged in a circumference located centrally with respect to the center of the circular lid. Their length exceeds the length of the hooks so much that a sufficient angle of rotation for the bayonet attachment becomes possible. The hooks thus slide in the grooves when the cover is turned. Hooks should not reach through the grooves to avoid damaging the interior of the outlet or the base of the cover on top of it. The locking cams of the hooks must therefore not rest behind the grooves, but the cross section of the grooves has a retaining shoulder to which the locking cams can engage. In order for the cover to be guided well, the hooks are made to correspond to the roundings of the grooves and they grip the gripping shoulders of the cover with pliers.

The sealing of the cover against the socket, but also against the grooves formed in the cover, is ensured by a sealing ring mounted between the frame formed on the cover and the side wall of the cover.

It is important that the locking hooks formed for the bayonet attachment of the cover get into the grooves designed on the bayonet flange of the socket when the cover is placed on top. The position of the grooves and thus the position of the hinge flap relative to the cover is chosen so that the locking hooks made on the cover in the socket made according to DIN 49442 fit into the grooves designed for the socket of the bayonet switch. The length of the groove must then be at least large enough to obtain a sufficient angle of rotation for attaching the cover.

In known sockets, it is necessary to know, on the one hand, the location of the locking hooks and, on the other hand, the location of the grooves formed in the socket flange before placing the cover on the socket so that the cover can be placed on the socket in the correct position. This step is substantially facilitated in the further development of the invention when the part of the front side of the cover which is not covered by the hinge flap is marked with a double arrow, by means of which it is detected when the cover has been opened and can thus be inserted or removed.

The invention is described in more detail below with reference to an embodiment and is shown in the drawings.

As shown in Figure 1, the hinge flap 2 is connected to the socket by a hinge 1. The hinge flap 2 shown in detail in Figures 3-7 in turn supports the cover 3 by means of hooks 5 which engage the slots 6 in the cover 3. The details of the cover are shown in Figures 8-10.

In order to fasten the cover 3 to the socket, a bayonet switch is designed, in which the locking hooks 4 formed on the cover 3 engage behind the socket flange 13.

The slits 6 are placed on the cover 3 concentrically opposite each other. Looking at the cross-section of the slots 6, they have a retaining shoulder 7 about halfway in height, to which the hooks 5 of the hinge flap 2 engage at their tips 8. Hooks 5 of uniformly made of the same material are fitted to the slots 6, especially with respect to their radius of curvature. Thus, the hooks 5 have a movement space inside the shoulder 7, which allows the cover 3 to be rotated about 30 degrees with respect to the hinge flap 2.

To seal the separating seam between the cover 3 and the socket, but also the gap 6, a sealing ring 9 is used, which is placed between the outer wall of the cover 3 and the frame 10 formed on the inner side of the cover.

The front side of the lid 3 is marked with a double arrow 11, which together with the symbols "Closed" and "Open" indicates whether the lid 3 is open or locked. In the "Open" position, the cover can be removed from the socket and also put back on.
