Definitions

  • the present invention relates to a connector housing with a housing body that is formed with at least one contact opening for mounting a contact element therein, and with at least one locking element for securing the contact element in the contact opening, the locking element comprising a locking member with a fixed end that is affixed to the housing body in a swivelling manner, and with a latching element for holding the locking element in its securing position.
  • the present invention relates to a set comprising at least two connector housings.
  • Connector housings with locking elements are known in the art. The locking elements are at least sectionwise inserted into contact openings for securing a contact element in a form- or force-fit manner.
  • known locking elements In order to protect the locking elements in this securing position, known locking elements have latching elements for establishing a latch connection with the housing body. With the known latching elements, however, insertion or mounting forces necessary for pushing the locking element in its securing position vary with differently shaped locking elements, which influences the ease of utilization of the connector housing.
  • an object underlying the invention is to provide a connector housing, which can be utilized independent of the shape of its locking element.
  • the object is achieved according to the invention for the connector housing mentioned in the beginning in that the latching element is arranged on a side of the locking element that faces away from the fixed end.
  • the object is achieved according to the invention in that the at least two connector housings are formed according to the invention, wherein the at least one locking element of one of the two connector housings differs in width from the at least one locking element of another of the at least two connector housings and in that the type and number of the latching elements of the one connector housing corresponds to or equals the type and number of the latching elements of the other connector housing.
  • latching element can be formed independently of the remaining locking element. Hence, it can be optimized with respect to utilization of the connector housing and in particular with respect to insertion or mounting forces that have to be applied for moving the locking element into its securing position and more particularly for establishing the latch connection between the latching element and the housing body.
  • the latching element can have a width, this width being less than half of the width of the locking element.
  • the latching element can be narrow compared to the locking element and the width of the latching element can be less than or equal to 40%, 30, 20%, 10%, 5% or 3% of the width of the locking element.
  • the width of the latching and of the locking element can be measured parallel to a width direction that extends from one side of the locking element to another side of the locking element, the sides extending away from the fixed end. A predetermined and in particular small width keeps the insertion or mounting forces stable and preferably small.
  • the locking element can comprise a predetermined amount of latching elements and in particular at least two, three, four, five or more latching elements per locking element.
  • the predetermined amount of latching elements can be independent of the shape and in particular of the width of the locking element.
  • latching elements when moving the locking element into its securing position, the same amount of latching elements have to be brought into the latching connection with the housing body, resulting in a constant mounting force, which is independent of the shape and particularly of the width of the locking element.
  • the latching elements can be formed separate from each other.
  • connection between the locking member and the housing body via the fixed end facilitates a movement of the locking element towards its securing position.
  • An easy way to establish such a connection is, if the fixed end is formed as a film hinge, which may be resiliently deformable in and against the swivelling direction.
  • the latching elements can be arranged spaced apart from each other, either at a constant distance to each other or at constant distances to certain structures of the locking element.
  • the latching elements can be arranged at constant distances to sides of the locking element.
  • the connector housing can comprise more than one and e.g. two, three, four, five or more locking elements.
  • each of the locking elements can be equipped with the same amount, e.g. two, of latching elements.
  • the latching elements of each of the locking elements can be similarly arranged, e.g. at selected distances to each other or to chosen structures of the connector housing.
  • the amount and the arrangement of the latching elements of one of the locking elements can correspond to or equal the amount and the arrangement of the latching elements of another one of the locking elements.
  • the latching element can be formed as a latching protrusion.
  • a latching protrusion can easily be detected by the user, who can therefore identify the actuating sections of the locking element, which he has to actuate for pressing the locking element into the securing position. If a visual or tactile detection of the latching elements is not necessary for handling the connector housing, the latching element can of another shape and can i.e. be formed as a latching recess in the alternative.
  • the latching protrusion can project away from the fixed end of the latching member. Such an embodiment of the latching protrusion avoids that it unintentionally interferes with one of the contact openings or the contact elements arranged in such openings.
  • the latching element can be formed as latching nose, the bridge of said nose facing away from the fixed end.
  • a width of the latching nose is preferably less than the width of the locking element and in particular less than or equal to 50%, 40%, 30%, 20%, 10%, 5% or 3% of the width of the locking element.
  • the width of the latching element can be less than and particularly a fraction of the width of the locking element, even reduced by the width of the latching element.
  • the locking element can be formed with the securing protrusion that projects from the locking member.
  • the latching element can be arranged between a base end of the securing protrusion, which base end is affixed to the locking member, and a free end of the securing protrusion.
  • the latching element does not protrude from the connector housing in the securing position of the locking element, preventing the creation of additional interference structures of the connector housing.
  • the locking element can plunge into the housing body without unintentional interference with one of the contact openings or the contact element arranged therein. This results in a compact design of the contact housing.
  • the securing protrusion can project from the locking member in a swivelling direction, in which the locking member can be swivelled towards its securing position.
  • a design with the securing protrusion projecting in the swivelling direction further improves the utilization of the connector housing, as the securing protrusion is not arranged in any of the actuating areas for the user.
  • the actuating areas can be shaped for ease of use and can in particular be flat, such that unpleasant pressure peaks to the user's fingers are avoided.
  • the latching elements can be aligned with each other, e.g. perpendicular to one of the contact openings.
  • the latching elements can be arranged at the same distance to the actuating area of each of the locking elements.
  • the housing body can be formed with the locking opening for at least sectionwise receiving a locking end of the locking element.
  • the locking protrusion of the locking element can be part of the locking end and can at least sectionwise or even fully be received in the locking opening in the securing position.
  • the locking end can comprise the latching element and the locking opening can be formed with a counter latching element for the latching element.
  • the counter latching element can be arranged on a side of the locking opening that faces the latching element in the securing position and that in particular faces the fixed end of the locking member.
  • the counter latching element can be shaped as a latching projection that protrudes towards the fixed end. If a visual or tactile detection of the counter latching element is not necessary, the counter latching element can be of another shape, for instance a latching recess.
  • the locking member can have a length between its fixed and its locking end that is larger than its width perpendicular to its length and to the swivelling direction.
  • the locking member may be a locking arm.
  • the connector housing comprises a larger amount of contact openings, e.g. up to seven, up to ten, up to sixteen or more contact openings, the width of the locking member can exceed its length.
  • the locking member can be shaped as a locking cover covering upper and/or lower sides of the housing body at least sectionwise or even fully and in particular the locking opening.
  • the locking arm may, however, cover one side the housing body at least sectionwise, too.
  • the securing protrusion can have a width which at least facilitates that a certain subset or amount of contact elements can be secured in their contact openings.
  • the securing protrusion may be designated as a securing beam or securing bar that essentially extends perpendicular to the one contact opening. If the securing protrusion is formed with a security lug, this lug can be a security bead extending perpendicular to the contact openings instead.
  • each contact opening may comprise one locking opening.
  • the locking opening may extend continuously perpendicular to the contact openings and intersect several contact openings.
  • the locking opening can be designated as a locking groove.
  • the counter latching element may also extend continuously perpendicular to the contact openings and may therefore be designated a counter latching rail. If, however, the counter latching element does not protrude towards the fixed end but away from the fixed end, it may be designated as a counter latching groove.
  • the type of latching elements may correspond to the size, form or cross-section and/or to the arrangement of the latching elements.
  • at least one of the locking elements of one connector housing can comprise latching elements that are essentially identical to the latching elements of the at least one of the locking elements of the other connector housing.
  • the at least one latching element of the connector housing can be arranged in a position on the locking element that is essentially identical to a position of the at least one latching element at the other connector housing.
