Abstract: A plug-and-socket connection includes a socket part on a mother board and a plug part on a daughter board. The plug part comprises a plug housing axially displaceably mounted on a daughter board. A securing mechanism latches the socket part in a latched position. The plug housing, in the insertion direction, is directly or indirectly supported on a push element in the form of a leaf spring with an angled part. The spring force of this leaf spring maintains the support until reaching the latching position. With a continued pushing movement, the support is automatically released by yielding of the leaf spring. In this manner the daughter board, after reaching the latching position, may be decoupled from the mother board.

Abstract: An insert-rack plug connection can be created between at least one sleeve portion (2) on a relatively fixed-position mother board (3) and at least one plug portion (4) on a relatively mobile daughter board (5).

In addition, engagement means (8) for engagement of the plug housing into an engagement position in the sleeve portion are provided on the plug housing. In the insertion direction (x), the plug housing (6) is supported either directly of indirectly on a spring-action thrust element (9), the spring force of said thrust element maintaining the support until the engagement position has been reached, and subsequently automatically releasing said support on continued thrust movement.

Abstract: A pre-fitted optical fiber section (2) is held in a plug ferrule (1) in such a way that it extends from a face (3) up to a lateral fusion access aperture in the plug ferrule (1). From the direction of an entry surface (7) at the cable-end, a bore (6) running coaxially to the optical fiber section also leads into the fusion access aperture. Within the fusion access aperture, the pre-fitted optical fiber section can be welded to the optical fiber (27) of an optical fiber cable (24) in the field. The plug ferrule is assembled from at least two components, of which one (8) possesses the outer jacket serving to center the plug ferrule and the other (10) possesses the fusion access aperture (4) and the bore (6). Both components comprise differing materials, which considerably facilitates manufacture.
