Abstract
A field bus module assembly includes a generally rectangular base module adapted for mounting on a fixed support, an input/output module, and a connecting module for connecting the input/output module with the base module, the base module including a lateral projecting portion adapted for insertion in sealed relation within a corresponding recess contained in the base module of an adjacent assembly. The base module includes a housing formed of a synthetic plastic insulating material, a plurality of bus bar conductors mounted on the housing, a protective cover member covering the bus bar conductors, and a mass of encapsulating material hermetically sealing the space around the cover.
Claims18
A field bus module assembly, comprising:
- (a) a generally rectangular base module (100) adapted for connection with a fixed horizontal support;
- (b) an input/output module (300);
- and
- (c) a generally rectangular connecting module (200) mounting said input/output module on said base module;
- (d) said base module including:
- (1) a base body (101) formed of synthetic plastic electrical insulating material, said base body having a lateral projecting portion (114) that is adapted to extend within a corresponding lateral recess (115) contained in an adjacent second base module, said base body having a horizontal lower surface containing an upwardly extending second recess (106) having a top wall;
- (2) a plurality of bus bar electrical contacts (102) mounted in transversely-arranged, laterally-spaced relation within said second recess adjacent said top wall;
- (3) a horizontal cover member (103) arranged in said second recess below said bus bar electrical contacts, said cover member being spaced upwardly above the horizontal plane containing said base body lower surface, thereby to define a chamber (110) in the bottom portion of said second recess;
- and
- (4) a first mass of encapsulating material (M) filling said chamber, thereby to hermetically seal said bus bar electrical contacts against moisture.
