Retaining frame

Abstract

Disclosed is a retaining frame for retaining plug connector modules and for installation in plug connector housings or for screwing onto wall surfaces, wherein the plug connector modules are inserted in the retaining frame, and retaining means on the plug connector modules interact with cut-outs or recesses provided on opposite wall parts (lateral parts) of the retaining frame. According to the disclosure, the retaining frame is designed in two halves connected to one another in an articulated manner and the cut-outs or recesses for retaining the plug connector modules are designed as openings in the lateral parts of the retaining frame. The retaining frame for inserting the plug connector modules is opened and subsequently closed, wherein the plug connector modules are held form-fittingly in the retaining frame via the retaining means on the plug connector modules.

DETAILED DESCRIPTION

(9) Represented in FIGS. 1 and 2 is a holding frame 1 for plug-in connector modules 2, wherein in FIG. 1 the holding frame is open, and is closed in FIG. 2. The holding frame 1 is designed, following the fitting of plug-in connector modules, to be mounted in plug-in connector housings (for which, see FIG. 4) or to be fastened, via an opening, to a fastening surface/mounting wall.

(10) The holding frame 1 is composed of two halves 4, 5, connected via hinge joints 3, having fastening ends 6, which are provided with fastening screws 7. The hinge joints in this case are provided at the fastening ends 6 of the holding frame 1, wherein the pivot capability of the frame halves 4, 5 is provided transversely to the lateral parts 8 of the holding frame 1. Shaped elements, which engage in corresponding recesses, are respectively provided at the fastening ends 6 of the holding frame, or of the lateral parts, to form the hinge joints 3. These shaped elements in this case are inserted into the recesses by lateral displacement of the lateral parts, wherein the lateral parts can then be pivoted (rotated) about the longitudinal axis A.

(11) After the lateral parts 8 are joined together, delimitation studs 16, realized here as grounding contacts, are fitted into the fastening ends, wherein the delimitation studs are each provided at the outer ends of the lateral parts 8, and the hinge joints 3 are thus located between the delimitation studs 16. This arrangement of the delimitation studs 16 prevents axial displacement of the lateral parts 8.

(12) The plug-in connector modules are provided with projecting, approximately rectangular holding means 9 (e.g., projections, lugs) and elastic latching hooks 10. Provided in the lateral parts 8 of the frame halves 4, 5 there are recesses 11, realized as openings that are closed on all sides, into which the holding means 9 go when the plug-in connector modules 2 are fitted into the holding frame 1.

(13) For the purpose of fitting the plug-in connector modules 2, the holding frame 1 is folded open, i.e., opened, wherein the frame halves 4, 5 are folded open about the hinge joints 3 to such an extent that the plug-in connector modules 2 can be inserted. For the purpose of pre-fixing the plug-in connector modules 2, during fitting the latching hooks 10 first engage beneath the lower edges 12 of the lateral parts 8 of the frame halves 4, 5.

(14) The frame halves 4, 5 are then folded together, i.e., the holding frame is closed, wherein the holding means 9 go into the recesses 11, causing the plug-in connector modules 2 to be held in the holding frame 1 in a secure, form-fitting manner.

(15) A detail view of a holding means 9 on a plug-in connector module 2 is represented in FIG. 3. According to an embodiment of the invention, the holding means 9 is realized substantially as a rectangular parallelepiped, and formed on the plug-in connector module 2. Two mutually adjacent corner regions of the holding means 9 are beveled and in each case form a triangular surface 9.1.

(16) The purpose of the beveled corner regions of the holding means 9 is that, according to an embodiment of the invention, the lower surface of the holding means 9 here is larger than the upper surface of the holding means 9.

(17) FIG. 4 shows a sectional representation through a recess 11 with a holding means 9 accommodated therein. In this case, the section of the representation is located in the outer region of the lateral part 8. The figure shows the corner regions in the lower region of the recess 11, which are beveled. The gap that can be seen between the recess 11 and the holding means 9 is only to aid illustration and, according to an embodiment of the invention, exists only to a minimal extent or is not present.

(18) To aid illustration, a recess 11 according to an embodiment of the invention is shown yet again in FIGS. 5 and 6. In this case, the recess 11 is shown in FIG. 5 as viewed toward the interior of the lateral part 8. The recess 11 is surrounded by six delimiting surfaces 11.1. Two triangular surfaces can be seen in the lower region of the rectangular recess 11. The triangular surfaces are part of the surfaces 11.1 delimiting the recess 11, and are provided to correspond to the triangular surfaces 9.1 of the holding means 9 of the plug-in connector module 2.

(19) The recess 11 of FIG. 5 is illustrated in greater detail, in three sectional representations, in FIG. 6. The lateral part 8 in this case has a first side 8.1, which is oriented inward and assigned to an inserted plug-in connector module 2. And a second side 8.2, which is disposed on the exterior of the holding frame 1.

(20) In this case, the section A-A is located in the central region of the recess 11. Fully visible at the bottom of the section is the triangular surface, which is a part of the surfaces 11.1 delimiting the recess 11. The section B-B is located centrally through one of the triangular surfaces. Also visible, in the lower region of the section B-B, is the complete triangular surface located behind. The section C-C is located in the outermost region of the recess 11, as a result of which, in the view C-C, the corner region has the tapering form according to an embodiment of the invention. The delimiting surface 11.1 shown at the bottom is in this case disposed at an angle of approximately 45 degrees in relation to the first side 8.1 and the second side 8.2.

(21) In general, in the following claims, the terms used should not be construed to limit the claims to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled.
