Embodiment Construction

[0018] figure 1 and figure 2 A plurality of juxtaposed electronic modules M of a programmable automation controller are shown.

[0019] The module comprises a housing 1 with side walls 1a, a front wall 1b and a metal rear wall 1c, which will also be referred to as the bottom of the module. It includes processor electronics on a printed circuit board in an enclosure.

[0020] The printed circuit is electrically connected to the interconnected printed circuit 2 at the base side via corresponding connectors 100 and 200 .

[0021] The interconnected printed circuit is carried by a support 3 , such as a metal panel, which is grounded. The interconnected printed circuit includes openings 20 .

[0022] The frame ground connection 4 connects the module to the panel from which it is insulated, through an opening 20 in the interconnection printed circuit. The insulator consists of an air gap or a layer of insulating material surrounding the opening.

[0023] The device 4 of the p...

Abstract

The invention discloses a frame grounding device of automation equipment. The device includes at least one movable interface module including processor electronics on at least one printed circuit electrically connected with an interconnect printed circuit carried by a support through a respective connector, the printed circuit is housed in a housing of a module fixed to the support and is electrically connected with the conductive portion of the support by a frame ground connection device, the frame ground connection device has a connection member fixed to the support and the module to establish mutual electrical contact between the module and the support. The connection member includes male and female members adapted to mate in a plug-in manner, and the interconnection printed circuit includes an opening through which at least one connection member passes when the module is mounted on the support.

Description

technical field [0001] The present invention relates to a frame ground connection, eg a ground connection, for automation equipment such as a modular programmable automation controller. Background technique [0002] A programmable automation controller comprising one or more juxtaposed removable interface modules, each module containing in a housing one or more processing electronics on printed circuit cards that can be accessed via appropriate connectors Electrically connected to interconnected printed circuits carried by one or more printed circuit boards. Supports interconnection between modules and connection to the central processing unit. The housing may be secured to the frame and electrically connected to the conductive portion of the frame through the frame ground connection. [0003] When the module is secured to the support and connected to the interconnection bus, it is preferred that the conductive parts of the support and the module are in electrical contact ...
