Advanced drill string inground isolator housing in an MWD system and associated method
First Claim
1. A housing arrangement for use as part of an inground tool for receiving a transmitter to transmit a locating signal from the inground tool, said housing arrangement comprising:
- a main housing for supporting the transmitter in an operating position while emanating the locating signal; and
a lid configured for removable installation on the housing such that at least a portion of the main housing and a portion of the lid are disposed in a confronting relationship to cooperatively define at least one elongated slot leading from an exterior of the housing arrangement to the transmitter with the transmitter received in the housing.

Abstract
A housing defines a through passage along its length and is configured to support a group of electrical isolators surrounding the through passage to form an electrically isolating break in a drill string such that each isolator of the group of isolators is subject to no more than a compressive force responsive to extension and retraction of the drill string. The housing defines a housing cavity to receive an electronics package having a signal port and is configured for electrical connection of the signal port across the electrically isolating break. A housing lid can cooperate with a main housing body to define elongated slots for purposes of enhancing the emanation of a locating signal. A housing arrangement can support electrical connections from an electronics package to bridge an electrically isolating gap.

5. A housing for use as part of an inground tool for supporting an electronics package having an output cable for carrying an output signal, said housing comprising:
-
a housing body that is electrically conductive and defines a cavity for receiving said electronics package such that the electronics package forms a first electrical connection to the housing body; and an intermediate housing that is electrically conductive and which is receivable on one end of the housing body to cooperate with the housing body in a way that forms an electrical isolation gap between the intermediate housing and the housing body, and the intermediate housing forms a second electrical connection with said cable such that the electronics package is electrically bridged across the gap.
