Abstract

In an existing interconnection assembly for an electronics cabinet back panel, a cable is connected through an adapter module to a conventional connector. The connector electrically and mechanically connects to a corresponding connector mounted to the back of the panel. The module provides filtration for the electrical signals passing through the cable. In particular, diode signal amplitude limiters are provided in the module to prevent excessive voltages from passing from the cable to the electronics within the cabinet. A problem has arisen with regard to the physical size of the components which must be coupled to the outside of the back panel. In addition, a significant labor expense is incurred in the customized hand wiring which must take place in order to fabricate the adapter module.

Modular Piggyback Connector

In an existing interconnection assembly for an electronics cabinet back panel, a cable is connected through an adapter module to a conventional connector. The connector electrically and mechanically connects to a corresponding connector mounted to the back of the panel. The module provides filtration for the electrical signals passing through the cable. In particular, diode signal amplitude limiters are provided in the module to prevent excessive voltages from passing from the cable to the electronics within the cabinet. A problem has arisen with regard to the physical size of the components which must be coupled to the outside of the back panel. In addition, a significant labor expense is incurred in the customized hand wiring which must take place in order to fabricate the adapter module. These problems are overcome by the invention which is shown in the figure. The connector component 5 of the invention consists of a modified multi-pin connector having a plurality of pins 10 mounted in an anchoring medium 12 within the connector body 8. The assembly is bolted by means of a flange to the back panel 27 of the existing cabinet. The pins 10 extend into the box cavity 21 and electrically and mechanically connect with respective ones of conductors in a flexible printed cable 16. The printed cable 16 can also be of a rigid construction, where appropriate. The pins 10 extend rearwardly into the cabinet cavity 21 and terminate at the end 14 which extends beyond the plane of the flexible printed cable 16. A second component of the invention is the filtration module 20. The module 20 consists of a plurality of female connectors 22 which slideably engage the end 14 of the male pins 10 of the connector 5 in a manner shown in the figure. The female connectors 22 are mounted in a potting medium 24 within a housing 26. Female connectors 22 are electrically connected to respective wires of printed circuit cable 28. The printed circuit cable 28 is then connected to respective ones of filtration modules 30 which may be diodes, capacitors, inductors, resistors, or the like, necessary...
