[0031] First of all, it is to be noted that in the different embodiments described, equal parts are provided with equal reference numbers and/or equal component designations, where the disclosures contained in the entire description may be analogously transferred to equal parts with equal reference numbers and/or equal component designations. Moreover, the specifications of location, such as at the top, at the bottom, at the side, chosen in the description refer to the directly described and depicted figure and in case of a change of position, these specifications of location are to be analogously transferred to the new position.

[0033] Finally, as a matter of form, it should be noted that for ease of understanding of the structure, elements are partially not depicted to scale and/or are enlarged and/or are reduced in size.

[0034] The electrical built-in plug connector, shown by way of example in the attached figures in a version as an 8+2 built-in plug connector with connection option to an electronic conductor board, has a housing 1. This may be made of a plastic material but also of a metallic material.

[0035] On the front end face, on the insertion side of a complementary cable plug connector, a rectangular and/or square mounting flange 2 is provided as a mounting structure projecting transversely to the longitudinal axis A of the housing 1 At two corners of this mounting flange 2 opposite one another with respect to the longitudinal central axis A, mounting bores 3 are formed in order to be able to fasten the built-in plug connector on a control panel, a device wall or the like by means of mounting screws, rivets or similar fastening means reaching through these mounting bores 3. The mounting flange 2 could also be designed to be circular, elliptical, having any desired polygonal circumferential edge, or in a similar fashion. Alternatively, mounting eyes having bores and laterally projecting from a cylinder-shaped housing 1 are also possible, wherein two eyes opposite one another with respect to the longitudinal axis A of the housing 1 are preferred.

[0036] In the shown exemplary embodiment as a male plug, the housing 1 is surrounded by a total of 10 contact pins 4, 5. They are held in a contact carrier 6 (see FIG. 3 and FIG. 4), which is preferably manufactured separately from the housing 1 and is inserted into the housing 1 in parallel with the longitudinal axis A of the same. The contact carrier 6 consists of an electrically insulating material, in particular of plastic, and leaves the end sections pointing to the complementary plug connector exposed. For the female embodiments, the contact carrier 4, which then extends all the way to the front end face of the housing 1, accommodates annular or hollow-cylindrical contact elements.

[0037] In the 8+2 variant of the built-in plug connector explained here, two contacts 4 are provided for the transfer of energy and eight contacts 5 are intended for data transfer. In this regard, the contacts 4 for the transfer of energy are preferably designed to have a greater diameter than the thinner contacts 5 for data transfer.

[0038] The contact elements, in this case the contact pins 4, 5, extend in parallel with the longitudinal axis A of the housing 1 and are guided outwards on the rear side of the contact carrier 4 at one end of the housing 1 or also through both components 1, 4, also in parallel with the longitudinal axis A of the housing 1, and protrude out of the housing 1 on its end face opposite the insertion side for the cable plug.

[0039] The end sections 41, 51 of the sections of the contacts 4, 5 situated outside the housing 1 are angled with respect to their sections situated inside the housing 1. These end sections 41, 51 typically extend transversely to the longitudinal axis A of the housing 1 and, at least starting from a certain distance from the contacts 4, 5, also in parallel with one another. At their outer-most ends, they transition into connection regions 42, 52 provided for connecting to an electronic conductor board. These end in a common plane E, which is situated parallel to the longitudinal axis A of the housing 1, and preferably also outside its enveloping lateral surface. The connection regions 42, 52 are arranged in groups, wherein the individual groups—as can be seen well in FIG. 4 and FIG. 5—are situated on at least three parallel straight lines G (see FIG. 4), which are part of the common plane E. In FIG. 5, these straight lines G would run through the connection regions 42, 52, perpendicular to the drawing plane.

[0040] The end sections 41, 51 may be designed as a direct continuation of the contacts 4, 5 and be brought from a direction parallel to the longitudinal axis A to a direction transverse thereto and parallel to one another by means of folding or bending. However, an embodiment as shown in the figures is preferred, in which the sections 41, 51 extending in an angled manner are manufactured as separate elements, which are then directly connected to the sections of the contacts 4, 5 guided to the outer side of the housing, for example by riveting, as can be seen in the drawings. Preferably, the end sections 41, 51 are designed as flat metal strips, wherein the connection sections 42, 52 preferably have a smaller width than the majority of the length of the end sections 41, 51.

[0041] The angled sections 41, 51 of the contacts 4, 5 are fixed in a common holding plate 9 just ahead of their connection regions 42, 52, from which holding plate 9 the connections regions 42, 52 jut out on the side facing the conductor board, in order to be connected to said conductor board. The common holding plate 9 is preferably provided with an extension 91 running along the housing 1, which extension 91 together with the holding plate 9 forms a full support and good connectability to the conductor board and also ensures the mechanically stable connection between the housing 1 and the precisely defined position of the connection regions 42, 52.

[0042] Preferably, the ends of the sections of the contacts 4, 5 guided out of the housing 1 in parallel with one another and with the longitudinal axis A have the same distance in the direction of the longitudinal axis A of the housing 1 as the parallel straight lines G and vice versa.

[0043] The contact carrier 6 preferably inserted into the housing 1 is fixed in the housing 1 on that side of the housing 1 on which the contacts 4, 5 are guided on its outer side, by means of a holding element, in this case preferably designed as a ring 7. In this regard, the ring 7 is designed to be projecting inwards, at least partially, from the rear end face of the wall of the housing 1, wherein it overlaps with the rear end face of the contact carrier 6 and thus prevents that it can be pushed rearward out of the housing 1. For this purpose, the ring 7 is fixedly connected to the housing 1 in at least one location. This connection can be established by means of crimping of a tongue 71 of the ring 7, which radially projects outwards and is guided between two dowel pins 8 of the housing 1, with these dowel pins 8.

[0044] The front insertion opening in the housing 1 preferably has a cutout 21 at at least one circumferential position, which cutout 21 continues in parallel with the longitudinal axis A of the housing 1 rearward into the interior of the housing. The contact carrier 6, as well, may have a recess 61 at a corresponding position. This cutout 21 and the recess 61 serve to receive a locking mechanism 10 of a known design, which is schematically shown in FIG. 2.

[0045] The exemplary embodiments show possible embodiment variants, and it should be noted in this respect that the invention is not restricted to these particular illustrated embodiment variants of it, but that rather also various combinations of the individual embodiment variants are possible and that this possibility of variation owing to the technical teaching provided by the present invention lies within the ability of the person skilled in the art in this technical field.
