摘要： An arrangement in a telecommunications system for fitting a connection block in a cover so that a complete connecting unit is obtained, which can be connected to the front edge of a circuit board or in the back plane of a rack containing circuit boards. The arrangement is characterized by a cover formed so that a standardized connection block can be inserted into the cover guidance via guiding pins in the cover through the screw holes in the block normally used for screwing the block to the cover. The cover is provided with resilient end walls from which bosses project towards the interior of the cover. When the block is inserted into the cover, the end walls (3) deflect outwardly but reassume their original position when the block is engaged against stops in the cover, the projecting bosses engaging over the edges of the short ends of the connection block to lock the block to the cover.

摘要： The invention relates to a device in a telecommunication system for connecting a first connecting units to a second connecting means, each comprising a connection block and a cover, to lock the connecting units to each other to form a bus member, and for connecting the bus member or either of the connecting units to the front edge of a circuit board or to the back plane of a magazine containing circuit boards. Each cover (2) is provided with a plurality of channel-like through recesses (2), so-called locking holes, along one long side. Lamellar locking springs (7) are insertable into these locking holes. The locking springs are formed with a wide and a narrower portion, the narrower portion being insertable from one side of the cover and retained by resilient snap action. The narrower portion of the locking spring projects in approximately to the middle of the locking hole, and the wide portion projects outside the front edge of the cover. The locking hole (2) is provided with a locking protuberance (6) at its rear edge. When connecting a first connecting units, the cover of which is provided with locking springs (7) to a second connecting means, the first portion of the locking spring lying outside the locking hole (2) on the first connecting units is inserted into the rear portion of the locking hole in the second connecting units, the locking protuberance (6) in the locking hole engaging, by resilient snap action in a recess (12) in the locking spring (7) to lock the connecting units to each other. On two sides of the recess (12) the locking spring is provided with sloping surfaces (13) which, when a locking spring is inserted into a locking hole without a locking protuberance, permits a solid but unlocked attachment by friction between the locking hole edge and the sloping surfaces.
