Abstract
Abstract The disclosure relates to mateable electrical connector block for connecting or disconnecting plural electrical signal lines one at a time when the blocks are mated together or uncoupled as the case may be; with sequent connections being separated from each other a maximum distance across the connector blocks thereby eliminating arcing over between such connections as they are being made or disconnected. The connector blocks further include means for automatically disconnecting residual high voltage from the contacts when the connector blocks are uncoupled from each other and the high voltage carrying contacts become dangerously exposed thereby.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A connector for mixed voltage signals with an auxiliary positive disablement of dangerous high voltage, comprising: a first connector block having a plurality of electrical receptacles recessed within protruding insulative sleeves, a second connector block having a plurality of cavities matingly receiving said insulation sleeves therein, electrical conductors projecting into said cavities and secured to male electrical contacts for pluggable connection to said electrical receptacles, said second electrical connector block having a dielectric piston slidably mounted in a piston chamber and having a pair of conductive shorting rods engaging two of said male electrical contacts thereby connecting them together electrically, said first connector block having a projecting dielectric plunger insertable in said piston chamber for displacing said piston and disengaging said shorting rods from said corresponding male contacts prior to pluggable connection of said male contacts and said receptacle contacts but after receipt of said sleeves in said cavities.
Claim 2
Dependent Claim
149 words
A connector for mixed voltage signals with an auxiliary positive disablement of dangerous high voltage, comprising: a first connector block having a plurality of electrical receptacles recessed within protruding insulative sleeves, a second connector block having a plurality of cavities matingly receiving said insulation sleeves therein, electrical conductors projecting into said cavities and secured to male electrical contacts for pluggable connection to said electrical receptacles, said second electrical connector block having a dielectric piston slidably mounted in a piston chamber and having a pair of conductive shorting rods engaging two of said male electrical contacts thereby connecting them together electrically, said first connector block having a projecting dielectric plunger insertable in said piston chamber for displacing said piston and disengaging said shorting rods from said corresponding male contacts prior to pluggable connection of said male contacts and said receptacle contacts but after receipt of said sleeves in said cavities.
Claim 3
Dependent Claim
40 words
The structure as recited in claim 1, wherein, said piston is provided with spring means for resiliently urging said shorting rods into engagement with said corresponding male contacts, said plunger slidably displacing said piston in opposition to said spring means.
Claim 4
Dependent Claim
29 words
The structure as recited in claim 2, and further including latching means for latching together said first and second connector blocks with said receptacles matingly engaging said male contacts.
Claim 5
Dependent Claim
44 words
The structure as recited in claim 1, wherein, said male contacts are mounted in said cavities at varied distances from open ends of said cavities thereby matingly engaging corresponding contacts at varied points in time as said sleeves are progressively inserted within said cavities.
