Definitions
- the invention relates to a security element for closing contact openings of the front part of a power socket according to the preamble of claim 1.
- Such security elements are intended to prevent the insertion of a pin-shaped object into a contact opening in the Metz socket. Only when two contact pins of a plug are pushed into the contact openings at the same time should the security element release the contact openings.
- Known security elements of this type are held movably essentially transversely to the connecting line of the contact openings of the mains socket. If a plug with contact pins is inserted into the contact openings, the security element is pushed out of the area of the openings due to the inclined surfaces arranged on it, so that the contacts of the connecting lines inside the mains socket are released for contacting. If a force is only exerted on an inclined surface, the safety element should tilt in its guides and thus be blocked, so that the contacts of the connecting lines inside the mains socket are not released.
- Such security elements are known for example from EP 539.093 and EP 646.990.
- the aim of the invention is to avoid these disadvantages and to propose an alternative solution for a security element or a power socket with a security element of the type mentioned at the outset, which guarantees safe opening and closing of the contact openings with smooth movement of the security element and at the same time the release of the contact openings Inserting an object in only one contact opening reliably prevented.
- the proposed measures ensure that when only a single pointed object is inserted into one of the contact openings of the power socket, the second paragraph of the inclined surface of the security element that extends into the other contact opening still makes it impossible to move it.
- the feature of claim 2 also ensures the exact displacement of the security element in depth. In order to move the shoulders of the inclined surfaces of the security element out of the contact openings, it is necessary not only to move the security element laterally along the guide slot, but also in depth. This will lift the heels out of the contact openings and only then will it be possible to move them sideways.
- the bridge and collar prevent the lateral guidance from being lost due to the depth shift.
- Fig.l is an axonometric view of the security element
- Mains socket Fig. 7 is an inside view of a front part of a mains socket without a security element
- FIG. 9 shows a detailed view from FIG. 8
- FIG. 10 shows a detailed view from FIG. 10
- FIG. 1 shows an axonometric view of a security element 1.
- This has inclined surfaces 2a, 2b, which on the one hand end on a surface of the security element 1 in a preferably curved section 3a, 3b and on the other hand in an opening 7a or partial opening 7b.
- the security element furthermore has a guide slot 5, which is partially surrounded by a collar 4, and guide cams 6, which are attached to the shoulders 3a, 3b opposite surface of the security element 1 are arranged.
- a spring 15 is mounted in a spring chamber 16 formed by the collar 4 and is supported on the one hand on the web 11 (shown in broken lines) protruding through the guide slot 5 and on the other hand on the collar 4.
- the spring 15 In its position shown in FIG. 2, the spring 15 is in the pretensioned state.
- the entire security element in FIG. 2 would shift to the left, as a result of which the web 11 moves into the spring chamber 16 and the spring 15 is preloaded even more.
- the security element 1 After removing the contact pins from the contact openings, the security element 1 is pushed back into its position blocking the contact openings (to the right in FIG. 2) by pressing the spring 15 on the web 11.
- FIG. 6 shows a front part 9 of a mains socket with a view from the outside of the contact openings 8.
- locking edges 10 are arranged, via which the front part 9 can be connected to a box-shaped part 12 (see FIG. 10) of the mains socket is.
- a lid (not shown) can be pivotally connected to the front part 9 via a hinge 11.
- FIG. 7 shows this front part 9 in a view from the inside without security element 1.
- the contact openings 8 are unprotected. After assembly of the front part 9 with the can-shaped part 12 of the mains socket and connection to the mains, a pointed object can be pushed from the outside through the contact openings 8 into the interior of the mains socket, as a result of which there is a high risk of electric shock.
- a security element 1 according to the invention, as can be seen in FIG protrude.
- inserts 10 projecting inwards are provided on the inside of the front part 9, which allow the security element 1 to be positioned exactly and permit movement only in the direction of the connecting line of the two contact openings 8 or, to a small extent, in accordance with the guide cams 6, to lift the paragraphs 3a, 3b out of the contact openings 8.
- FIG. 9 shows a detailed view of the security element 1 from FIG. 8.
- the web 11 is guided through the slot 5 and is fixedly connected to the front part 9.
- the spring 15 is arranged between the collar 4 and the web 11 in the prestressed position.
- the embodiment according to the invention also makes it unnecessary to maintain extreme tolerances around the production area in order to guarantee the functioning of the security element, and the contact openings are blocked by the shoulders of the inclined surfaces of the security element.
