Abstract
Abstract A connection system for host equipment is disclosed. The system includes a plug-in electronic module and a power supply cable for plug-in connection to said module. The host equipment includes a housing for the module which effectively precludes access to the module except at one exterior end thereof. An end plate at an exterior end of the module includes a handle facilitating removal of the module from the housing. The end plate further comprises a power supply cable jack for mating with a plug of the power supply cable. The jack and the plug are so located and adapted to render ineffective the handle when the plug is mated with the jack, thereby requiring the service personnel to remove the power supply plug from the jack before removing the module from the housing.

Claim 1
Independent Claim
138 words
A connection system for a host system including a plug-in electronic module and a power supply cable for plug-in connection to said module, said system comprising: said host system including a housing for said module effectively precluding access to said module except at one exterior end thereof, said module including an end plate at said exterior end, said end plate including handle means facilitating removal of said module from said housing, said module end plate further comprising power supply cable jack means for mating with a plug of said power supply cable, said jack means and said plug being so located and adapted to render ineffective said handle means when said plug is mated with said jack, thereby requiring service personnel to remove said power supply plug from said jack means before removing said module from said housing.
Claim 2
Dependent Claim

A connection system for a host system including a plug-in electronic module and a power supply cable for plug-in connection to said module, said system comprising: said host system including a housing for said module effectively precluding access to said module except at one exterior end thereof, said module including an end plate at said exterior end, said end plate including handle means facilitating removal of said module from said housing, said module end plate further comprising power supply cable jack means for mating with a plug of said power supply cable, said jack means and said plug being so located and adapted to render ineffective said handle means when said plug is mated with said jack, thereby requiring service personnel to remove said power supply plug from said jack means before removing said module from said housing.
Claim 3
Dependent Claim
76 words
The connection system set forth in claim 1 wherein said handle includes an opening to provide a finger grip to facilitate removal of said module from said host equipment housing, and wherein said jack means is placed adjacent to said handle means, and further wherein said plug is sized so as to block off said opening when mated with said jack means, thereby effectively preventing removal of said module before disconnection of said power supply cable.
Claim 4
Dependent Claim
49 words
The connection system set forth in claim 1 wherein said handle is effectively surrounded by said plug when mated with said jack so that service personnel must remove said plug from said jack means in order to gain access to said handle for removing said module from said housing.
