Abstract
Abstract Disclosed herein is a shield connection device for connecting EMI shielded cable shield to an EMI enclosure, the device includes an electrically conductive body defining a shield termination enclosure, the body having a plurality of openings extending through the body, the openings substantially parallel to longitudinal axis of the body and the body having means for accessing the opening. The connection device includes means adjacent the access means for applying fixable electrically conductive material to the opening through the access means for electrically connecting EMI cable shield thereto. In a preferred embodiment of the invention, the means for applying fixable electrically conductive material in the form of solder defines a heat-recoverable sleeve with a preform of solder on its interior. Sufficient material is provided for filling the opening with electrically conductive material to block EMI paths through the opening.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
144 words
A shield termination enclosure for terminating one or more EMI shielded cables to be inserted therein and connected thereto, the enclosure comprising: an electrically conductive body having a longitudinal axis and an outer periphery and having a plurality of openings extending therethrough, the openings being substantially parallel to said axis and each opening having a corresponding access means for accessing the opening, each access means comprising a groove in the outer periphery of the body which defines means for inspecting the EMI cable shield within the opening and for inspecting a joint formed between the body and the EMI cable shield, said openings capable of receiving EMI cable shield to be inserted within the openings and said access means allowing the flow of fixable electrically conductive material to connect cable shield to the body and to block radiated EMI from passing through the openings.
Claim 2
Dependent Claim
144 words
A shield termination enclosure for terminating one or more EMI shielded cables to be inserted therein and connected thereto, the enclosure comprising: an electrically conductive body having a longitudinal axis and an outer periphery and having a plurality of openings extending therethrough, the openings being substantially parallel to said axis and each opening having a corresponding access means for accessing the opening, each access means comprising a groove in the outer periphery of the body which defines means for inspecting the EMI cable shield within the opening and for inspecting a joint formed between the body and the EMI cable shield, said openings capable of receiving EMI cable shield to be inserted within the openings and said access means allowing the flow of fixable electrically conductive material to connect cable shield to the body and to block radiated EMI from passing through the openings.
Claim 3
Dependent Claim
166 words
A shield connection device, comprising: an electrically conductive body defining a shield termination enclosure including an electrically conductive body having a longitudinal axis and an outer periphery and having a plurality of openings extending therethrough, the openings being substantially parallel to said axis and each opening having a corresponding access means for accessing the opening, each access means comprising a groove in the outer periphery of the body which defines means for inspecting the EMI cable shield within the opening and for inspecting a joint formed between the body and the EMI cable shield, said openings capable of receiving EMI cable shields to be inserted within the openings; and means adjacent and in contact with each access means for applying fixable electrically conductive material to each opening through each respective access means for electrically connecting EMI cable shield to be inserted within the opening to the body and for filling the opening with fixable electrically conductive materials to block radiated EMI from passing through the openings.
Claim 4
Dependent Claim
