Abstract: A card edge connector allows a modular jack to be electronically connected to a PCMCIA Type III communications card. The card edge connector includes a modular jack with a main body portion having a top surface, a bottom surface, a front surface and a rear surface. A receptacle is disposed entirely within the front surface of the modular jack and the receptacle is sized and configured to receive a RJ series connector plug such that no portion of the plug extends through either the top surface or the bottom surface of the modular jack. A connector attached to the rear surface of the modular jack and the connector includes a socket sized and configured to receive a portion of a printed circuit board disposed within the communications card. Desirably, the card edge connector includes at least one contact pin including a plug engaging portion that extends into the receptacle and a printed circuit board engaging portion that extends into the socket.

Abstract: A housing for receiving printed circuit boards whose components form at least parts of a communication system, comprising a housing cover and a connection area which is accessible from the outside. A main printed circuit board is arranged between the base housing part and a cover part. Plug-in devices for at least one extension printed circuit board are provided in an extension area of the main printed circuit board. A first hood is provided in order to cover the extension area. The hood has push-through openings arranged towards the connection area, corresponding to plug-in devices on at least one extension printed circuit board in an assembled state. The first hood can engage with the cover part by means of a lock connection whereby said lock connection can only be released using a tool.

Abstract: The invention relates to a plug-in adapter for establishing an electrical connection between contacts of a plug, which is fixed to the end of a cable, and contact surfaces of a patch panel, which are formed on the edge of a printed circuit board. The plug-in adapter comprises a base body with a first receiving shaft designed for the insertable reception of the plug, a second receiving shaft designed for the insertable reception of the patch panel, and with contact bodies in the first and second receiving shafts. The electrical connection is established between corresponding contact bodies by a respective connecting element situated in the base body.

Abstract: The invention relates to a patch panel for mounting on a wall or in a subrack, comprising a housing part, which can be mounted on ends located on respective faces by means of angle brackets and which has a front cover provided in the form of a patch panel for routing data waiting on lines of an incoming cable to lines that can be connected via connecting devices on the front cover. An angle bracket is provided on each end and has a fork-type spring detent that can be inserted at the front and rear into guide slots, which are provided for insertably accommodating the fork-type spring detent on the ends that are situated on opposite sidewalls of the housing part, and the fork-type spring detent can be snapped in by means of corresponding detent means.

Abstract: A first printed circuit board (principal printed circuit board) is placed onto a housing frame having a stepped contour in a front edge region of the housing. The first printed circuit board is introduced into a receptacle of the frame provided with an entry bevel and, when put in place, is automatically interlocked by interlocked elements preferably arranged at an opposite side. Additional printed circuit boards can be inserted into guide elements present at the backplane, being inserted under this first printed circuit board. Their ultimate position is compelled by corresponding holder elements. In this ultimate position, each printed circuit board that is introduced and lies parallel to the backplane is interlocked by an interlock element that takes effect in this position. The additional, second printed circuit boards can be inserted independently of the first printed circuit board and are preferably provided for optional add-ons.

Abstract: A housing is provided with a base part to receive a plurality of equipment units, such as primed circuit boards. To facilitate access to terminal regions of the circuit boards, a two-part cover is securable to the base part, wherein a first cover part has an access opening to the terminal regions, and a ventilated second cover part covers the terminal region in a snap-fit manner. The terminal regions are thus easily accessible for measuring or testing. Preferably, the second cover part is manually releasable, without use of a tool.
