Abstract
Abstract A read/write head lead assembly includes a terminator with a housing having a space adapted to receive a plurality of leads into which a plurality of electrically conductive contacts, each having a first portion within the space and a second portion extending from the housing to a location external the space, the second portions having contact surfaces in a common plane, to permit soldering to a preamplifier circuit board and a plurality of head leads with each of the head leads electrically connected with one of the contacts at a location within the space.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
131 words
A terminator for a plurality of small diameter leads comprising: a housing forming a space adapted to receive a plurality of leads, said housing having a recess below said space; a plurality of electrically conductive contacts each having a first portion within said space and a second portion extending from within said space to a location external to said housing, said second portions having contact surfaces in a common plane, said contact surfaces having a substantially planar portion adapted for soldering, whereby leads may be electrically fixed to said contacts which extend from said housing to permit said terminator and thus said leads to be attached to a printed circuit board; and a damping resistor electrically connected across two of said contacts and wherein said resistor is disposed within said recess.
Claim 2
Dependent Claim
131 words
A terminator for a plurality of small diameter leads comprising: a housing forming a space adapted to receive a plurality of leads, said housing having a recess below said space; a plurality of electrically conductive contacts each having a first portion within said space and a second portion extending from within said space to a location external to said housing, said second portions having contact surfaces in a common plane, said contact surfaces having a substantially planar portion adapted for soldering, whereby leads may be electrically fixed to said contacts which extend from said housing to permit said terminator and thus said leads to be attached to a printed circuit board; and a damping resistor electrically connected across two of said contacts and wherein said resistor is disposed within said recess.
Claim 3
Dependent Claim
21 words
A terminator according to claim 1 wherein said contacts include portions to permit connection of a resistor outside of said space.
Claim 4
Dependent Claim
13 words
A terminator according to claim 1 wherein said housing is made of plastic.
Claim 5
Dependent Claim
22 words
A terminator according to claim 1 and further including an opening in said housing to receive a tubing which surrounds said leads.
Claim 6
Dependent Claim
106 words
A read/write head lead assembly comprising: a terminator including: a housing forming a space adapted to receive a plurality of leads; a plurality of electrically conductive contacts each having a first portion within said space and a second portion extending from within said space to a location external to said space, said second portions having contact surfaces in a common plane, said contact surfaces having a substantially planar portion adapted for soldering; a plurality of head leads each of said head leads electrically connected with one of said contacts at a location within said space; and a damping resistor electrically connected across two of said contacts.
Claim 7
Dependent Claim
106 words
A read/write head lead assembly comprising: a terminator including: a housing forming a space adapted to receive a plurality of leads; a plurality of electrically conductive contacts each having a first portion within said space and a second portion extending from within said space to a location external to said space, said second portions having contact surfaces in a common plane, said contact surfaces having a substantially planar portion adapted for soldering; a plurality of head leads each of said head leads electrically connected with one of said contacts at a location within said space; and a damping resistor electrically connected across two of said contacts.
Claim 8
Dependent Claim
46 words
A read/write head lead assembly according to claim 5 and further including protective tubing surrounding said head leads and an opening in a wall of said housing through which said leads surrounded by said tubing pass, said tubing adhesively attached to said housing at said opening.
Claim 9
Dependent Claim
18 words
A read/write head lead assembly according to claim 5 wherein said resistor is disposed outside of said space.
Claim 10
Dependent Claim
