Abstract
An electrical connection device (1), especially in the form of a connecting box, comprises a housing (2) having a wall (4) delimiting an inner space (3), electrical components (5) arranged in said inner space (3) and having at least two connecting portions (6, 7, 8), and at least two connecting holes (9, 10, 11) passing through the wall (4), through which external elements (12) connectable to the connecting portions (6, 7, 8) can be guided into the inner space (3). The connection device (1) further comprises a mechanical safety element (13) having a number of stop elements (14, 15, 16) that corresponds to the number of connecting portions (6, 7, 8), which stop elements (14, 15, 16) provide a mechanical stop for the external elements (12).
Claims46
An electrical connection device, in particular in the form of a connecting box or a plug-in connector, comprising
- a housing having a wall delimiting an inner chamber,
- electrical components situated in the inner chamber and having at least two connecting portions, and
- at least two connecting openings passing through the wall, through which external elements connectable to the connecting portions can be routed into the inner chamber, wherein
- the connection device further comprises a mechanical fastening element having a number of stop elements which corresponds to the number of connecting portions, which stop elements provide a mechanical stop for the external elements,
- wherein said stop elements are provided, in each case, by a stop surface on the fastening element, by means of which stop surface the mechanical stop can be provided for the external element when the external element is inserted;
- wherein the fastening element comprises at least two recesses, wherein each of the recesses is partially or completely enclosed by one stop surface, and wherein one of the external elements can be routed through one recess in each case, and wherein the stop surface is located behind the recess relative to an insertion direction of the external element;
- and
- wherein the connecting portions are designed essentially as a cylinder having a central axis, wherein the fastening element is designed so as to be movable relative to the housing transversely to the central axis, and/or wherein the recess is designed to cylindrically enclose a central axis at least in sections or entirely, which central axis extends in parallel to the central axis of the connecting portion, wherein the central axes are offset with respect to each other.
