MAGNETIC DETECTION APPARATUS AND METHOD OF MANUFACTURING SAME |
摘要 |
A magnetic detection apparatus (magnetic locator) comprises a housing constituted by a first integral molded plastic unit and a second integral molded plastic unit that are joined. The first unit has a tube with a plate at one end thereof transverse to the length of the tube, the plate having an opening through which a magnetic sensor assembly is inserted into the tube. The second unit has a cover open at one end and having a tubular handle at the opposite end, by which the user may grasp the apparatus. Attachment of the cover to the plate closes the open end of the cover to provide a casing. Magnetic sensors are mounted on a channel or angle structural member that is rigidly attached to the chassis of an electrical unit mounted in the casing. Sound from a loudspeaker mounted on the chassis is transmitted through the handle to the exterior of the apparatus. The chassis also supports a meter that is visible through an opening in an end wall of the cover adjacent to the handle.
