Holding frame for a plug connector and methods of populating same

1. A holding frame arrangement for a plug connector for receiving similar and/or different modules, comprising:

a base frame which defines a plane transverse to an insertion direction of a module into the holding frame arrangement, and which has mutually opposite end faces and mutually opposite side walls; and

one or more mounting clips, each of which having two mutually opposite flanges,

wherein each of the flanges has a window for receiving a respective latching lug of a module and a fixing tab, and

wherein each mounting clip is adapted to be mounted on a respective module, such that the module fitted with the mounting clip and inserted into the base frame abuts with the latching lugs of the module against respective upper edges of the side walls, in the insertion direction, wherein the fixing tabs engage with respective lower edges of the side walls, in the insertion direction, so that the inserted module is fixed in place at least along the insertion direction.

2. The holding frame arrangement according to claim 1 , wherein the flanges are connected to each other.

3. The holding frame arrangement according to claim 1 , wherein each flange has at least one latching tab adapted to engage with a lower edge of the module, in the insertion direction.

4. The holding frame arrangement according to claim 1 , wherein the base frame has recesses which extend in the insertion direction from an upper edge of the base frame, in the insertion direction, each of the recesses being adapted to at least partially accommodate a latching lug of a module.

5. The holding frame arrangement according to claim 1 , wherein the fixing tabs are adapted for engagement with the lower edges of the side walls of the base frame.

6. A holding frame for a plug connector for receiving similar and/or different modules, comprising:

a base frame which defines a plane transverse to an insertion direction of a module into the holding frame, and which has mutually opposite end faces and mutually opposite side walls,

wherein the side walls of the base frame each have stops for latching lugs of the module,

wherein adjacent to at least one of the stops, the base frame has a portion which protrudes in the opposite direction to the insertion direction and which is provided with a locking member which is pivotable about a pivot axis oriented transversely to the side walls, and

wherein the locking member is adapted to adopt an insertion position that allows the module to be inserted in the insertion direction into the holding frame, and a holding position in which an inserted module is held by the latching lug of the module between the at least one of the stops and the locking member.

7. The holding frame according to claim 6 , wherein the locking member has a yielding portion which projects into a path of the latching lug in the insertion position and is adapted to yield in such a way, when the latching lug is inserted, that the locking member is pivoted at least partially from the insertion position to the retention position by insertion of the module.

8. The holding frame according to claim 6 , comprising a blocking member which is adapted to prevent the locking member from pivoting back to the insertion state when the holding frame is in the holding state.

9. A holding frame arrangement for a plug connector for receiving similar and/or different modules, comprising:

a base frame which defines a plane transverse to an insertion direction of a module into the holding frame and which has mutually opposite end faces and mutually opposite side walls; and

at least two flange parts, which are attached to the side walls of the base frame opposite each other, wherein each flange part extends inside the base frame along an inner face of the base frame in the opposite direction to the insertion direction and beyond an edge of the base frame in the opposite direction to the insertion direction, wherein each flange part has at least one latching window, in the region extending beyond the edge of the base frame, as a latching element for receiving a latching lug of the module, wherein the flange parts are designed to undergo elastic bending and deformation between an insertion state which allows the module to be inserted into the holding frame in the insertion direction, and a holding state in which an inserted module is fixed in place at least along the insertion direction by the latching lug engaging into the latching window,

wherein each flange part is in form-locking engagement with the base frame, at least with regard to a relative displacement along the insertion direction, and has at least one clip section extending above a lower edge of the base frame into the base frame, through the base frame and/or around an edge of the base frame, and

wherein release of the form-locking engagement is prevented by the inserted module.

10. The holding frame according to claim 9 , wherein the form-locking engagement between the flange part and the base frame is provided by engagement of at least one undercut on and/or in the flange part with at least one undercut on and/or in an inside of one of the side walls of the base frame, and

wherein the flange part and the base frame are designed so that:

a) engagement can be produced and/or released by pivoting the flange part about the edge of the base frame; or

b) engagement can be achieved by de-tensioning an elastic deformation of at least a part of the flange part when moving the flange part relative to the base frame in the insertion direction along an inner side of one of the side walls.

11. The holding frame according to claim 10 , wherein the flange parts are connected to each other by a web extending along the end face of the base frame, wherein the outer dimensions of the flange parts, including the web in the plane defined by the base frame, are determined according to the inner dimensions of the base frame.

12. The holding frame according to claim 10 , wherein the engagement of the undercuts produces a form fit that prevents movement of the flange part relative to the base frame in the opposite direction to the insertion direction, wherein such a form fit that also prevents movement of the flange part relative to the base frame in the insertion direction is formed by the at least one clip section with the base frame.

13. The holding frame according to claim 10 , wherein the clip section has a guide portion which is guided in a groove and/or a slot in the base frame when the flange part is moved relative to the base frame.

14. The holding frame according to claim 9 , wherein the at least one clip section extends into a recess and/or an opening in one of the side walls of the base frame and fills the recess and/or the opening.
