Description

The invention relates to a cover for arrangement on a multi-pole plug element.

Covers are usually used to cover certain areas or elements to which they are arranged in order to protect them, for example, from dirt and dust, but also from moisture. Covers can have different shapes and configurations. A cover according to the preamble of claim 1 is made US 4,842,547 A known.

The invention is based on the object to provide a cover available, which is suitable for use on a multi-pin plug element, the cover can allow targeted guidance of the plurality of cables attached to the plug element.

In a cover of the type described in more detail above, this object is achieved by a cover according to claim 1.

Advantageous embodiments and advantageous developments of the invention are specified in the dependent claims.

The cover according to the invention is substantially formed in two parts by the cover has a first housing part and a second housing part. Due to the two-part design of the cover, the handling of the cover for a user can be simplified. When mounting the cover on the plug element, only the first housing part is initially mounted on the plug element. In a next step, the cables fastened to the plug element are brought into the correct position before the second housing part is mounted on the plug element and connected to the first housing part. The cover has two spaced-apart openings through which the cable mounted on the plug element can be passed, wherein the cables are guided into the cover via a first opening and the cables are led out of the cover again via the second opening, wherein the Openings allow a targeted and orderly leadership of the cable from the plug element and also from the cover. The direction of the leadership of the cable is determined by the position of the two openings to each other. The two openings each extend over both housing parts, so that the cables in the not yet connected state of the housing parts with each other in the openings of the one housing part, which is already mounted on the plug element, laterally inserted or can be inserted and thus not in a complicated manner by a completely limited opening, which would be given if the two housing parts at this time the positioning of the cable in the cover would be already connected to each other, must be passed. The two openings are arranged offset to one another, wherein the two openings are arranged offset from one another such that a plane spanned by the first opening to a plane spanned by the second opening at an angle between 40 ° and 90 °, preferably at an angle between 50 ° and 80 °, is formed. The two openings are thus not arranged directly above one another, and thus not arranged parallel to one another. Due to the staggered arrangement of the openings, in that the planes respectively defined by the openings are each arranged at an angle of> 0 ° relative to one another, the cables are guided in a deflected manner within the cover, so that the cables emerge bent out of the cover, starting from the connector element, and thus can be led away laterally from the plug element and the cover. This can be advantageous, in particular in the case of small or spatially limited installation spaces. The curved guidance of the cables within the cover and the staggered arrangement of the openings to each other, the view of a user on the openings of the cover on the slots of the male member through which the cables are inserted into the male member, can be efficiently blocked, whereby the visual impression can be improved for the user. Furthermore, this can be particularly effective by means of the special design of the cover the penetration and deposition of dust and dirt on the plug element and in particular on the slots of the Plug element can be prevented. The cover is further adapted in shape to the multi-pin plug element that it can produce the effect of an arrangement of a further connector element that would be placed on the multi-pin plug element for the user. Preferably, the outer dimensions of the cover correspond to the outer dimensions of the plug element, so that in the mounted state, the walls of the cover can be substantially flush with the walls of the plug element.

In order to facilitate the mounting of the cover on or on the plug element, it may be provided that on the first housing part and on the second housing part in each case two oppositely arranged guide portions are formed, by means of which the first housing part and the second housing part separated by means a sliding movement can be mounted on the plug element. By means of the guide areas, the housing parts can each be pushed laterally separated from each other on the plug element. Due to the possibility of pushing the housing parts onto the plug element, the mounting of the cover on the plug element can be done safely and specifically. In addition, the sliding over the guide areas allows a positive connection of the cover with the plug element. The Aufschiebeweg the housing parts on the connector element is preferably limited such that the housing parts can only be pushed from the outside to the connector element until they are flush with their trained perpendicular to the guide walls wall with the plug element, so that the housing parts not on the entire length of the Plug element can be moved. If the two housing parts are connected to one another, it is possible to prevent the cover from being removed from the plug element in the installed state in which the two housing parts are connected to one another. This allows a secure attachment of the cover to the plug element. A removal or removal of the housing parts of the plug element is then only possible if the two housing parts were previously separated from each other again, so that the housing parts can be pushed off in opposite directions from the male member to the outside and removed. The guide regions are preferably formed in the region of the first opening, wherein the guide regions preferably at least partially delimit the first opening.

The guide regions can be designed in such a way that they each have a curved guide rail which, in the mounted state, engages behind fastening elements formed on the plug element. The bending of the guide rails may be formed such that the guide rails are each U-shaped or C-shaped bent, so that the guide rails can engage behind the fastening elements formed on the plug element, which may be hook-shaped example, preferably from below and thus the Guide rails can surround the fasteners at least partially. In this way, a secure and stable attachment of the housing parts of the cover to the connector element can be achieved.

In order to prevent the cables led out of the covering hood via the second opening from being damaged at an edge region of the second opening, the second opening may be surrounded by a bead of material. The bulge material is preferably formed as a material thickening in the edge region of the opening, which is formed round, so that the edge region of the opening has a radius. A sharp-edged edge area around the opening can be prevented.

For joining the two housing parts together, it is preferably provided that the first housing part and the second housing part via a plug connection are detachably connected to each other.

The connector may have a plurality of pins, preferably cylindrical pins, which can engage in the mounted state in each case a receiving opening. For example, the pins may be formed on the first housing part and the receiving openings on the second housing part, or vice versa. Furthermore, it is also possible that both pins and receiving openings can be formed on the first housing part and on the second housing part. When plugged or mounted state of the housing parts, the pins can be locked in each case a receiving opening, so that a secure and easy to handle plug connection can be formed by means of the pins and the receiving openings.

In order to bundle the guided through the cover cable and thus to allow an orderly and directed removal of the cable out of the cover, the cover may have a cable bundling element. The cable bundling element may be fastened to the first housing part and to the second housing part, wherein the cable bundling element may be guided by a through opening formed on the first housing part and by a through opening formed on the second housing part. The cable bundling element can thus form a further connection between the first housing part and the second housing part, wherein the force applied by the cable bundling element when bundling the cables can be evenly distributed to both housing parts by the leadership of the cable bundling element by both housing parts.

Preferably, the cable bundling element may be a cable tie. However, the cable bundling element can also be formed by other elements, such as a cord, a hose or a clamp.

To identify the cover or the lead out of the cover cable, the cover may have a receiving area for receiving a marking element. The marking element may preferably have a labeling surface, which may be labeled as desired. The receiving area may be formed in the form of a groove formed on an outer surface of the cover, wherein for attaching the marking element to the cover, the marking element, which may be formed, for example, as a marker plate, can be inserted into the groove.

In order to increase the capabilities of the cover and in particular to be able to increase the flexibility in the leadership of the cable within the cover and out of the cover, on one wall of the first housing part and / or on a wall of the second housing part one or more of the Wall be formed detachable wall sections. The detachable wall sections may be limited, for example, by a perforation, so that the user himself can easily separate these wall sections via the perforation as needed from the respective wall of the cover.

The invention will be explained in more detail below with reference to the accompanying drawings with reference to a preferred embodiment.
