Abstract
Abstract A loadbreak connector having a male contact retractable to a cocked position and positively actuated to an extended position for positive engagement with an associated high voltage connector. Trigger apparatus initially retains the contact in a retracted position. The contact includes venting structure to dissipate and cool arc generating gases evolved upon connection of the contact to the high voltage connector.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
114 words
An electrical connector, comprising: a housing, a conductive shield provided over the housing, an electrical insulation layer provided over the shield, a contact at least partially retractable internally of said housing, connection means associated with said contact for permitting said connector to operate as an electrical termination, urging means in said housing for positively urging said contact to a substantially extended position protruding from said housing, whereby connection of said contact can be accomplished to another electrical connector, trigger means on said connector for additionally retaining said contact in a position at least partially retracted internally of said housing and for subsequently allowing extension of said contact to a position protruding from said housing.
Claim 2
Dependent Claim
114 words
An electrical connector, comprising: a housing, a conductive shield provided over the housing, an electrical insulation layer provided over the shield, a contact at least partially retractable internally of said housing, connection means associated with said contact for permitting said connector to operate as an electrical termination, urging means in said housing for positively urging said contact to a substantially extended position protruding from said housing, whereby connection of said contact can be accomplished to another electrical connector, trigger means on said connector for additionally retaining said contact in a position at least partially retracted internally of said housing and for subsequently allowing extension of said contact to a position protruding from said housing.
Claim 3
Dependent Claim
114 words
An electrical connector, comprising: a housing, a conductive shield provided over the housing, an electrical insulation layer provided over the shield, a contact at least partially retractable internally of said housing, connection means associated with said contact for permitting said connector to operate as an electrical termination, urging means in said housing for positively urging said contact to a substantially extended position protruding from said housing, whereby connection of said contact can be accomplished to another electrical connector, trigger means on said connector for additionally retaining said contact in a position at least partially retracted internally of said housing and for subsequently allowing extension of said contact to a position protruding from said housing.
Claim 4
Dependent Claim
114 words
An electrical connector, comprising: a housing, a conductive shield provided over the housing, an electrical insulation layer provided over the shield, a contact at least partially retractable internally of said housing, connection means associated with said contact for permitting said connector to operate as an electrical termination, urging means in said housing for positively urging said contact to a substantially extended position protruding from said housing, whereby connection of said contact can be accomplished to another electrical connector, trigger means on said connector for additionally retaining said contact in a position at least partially retracted internally of said housing and for subsequently allowing extension of said contact to a position protruding from said housing.
Claim 5
Dependent Claim
39 words
The structure as recited in claim 1, wherein said contact is provided with venting means in communication with the interior of said housing for dissipating and cooling the evolved arc generated gases away from a surface of said contact.
Claim 6
Dependent Claim
27 words
The structure as recited in claim 1, and further including: retainer means for retaining said contact in at least partially protruding relationship with respect to said housing.
Claim 7
Dependent Claim
27 words
The structure as recited in claim 1, wherein said connection means includes a key secured to said contact, and said housing includeS a keyway receiving said key.
Claim 8
Dependent Claim
28 words
The structure as recited in claim 4, wherein said contact means is slidably actuated in respect to said housing, and said key is slidably received in said keyway.
Claim 9
Dependent Claim
19 words
The structure as recited in claim 1, wherein said contact is provided thereon with a subliming arc extinguishing material.
Claim 10
Dependent Claim
49 words
The structure as recited in claim 1, wherein said trigger means includes a portion protruding from said housing and adjacent to said contact, whereby upon engagement of the protruding portion with another electrical connector, said trigger means allows extension of said contact to a position protruding from said housing.
Claim 11
Dependent Claim
60 words
The structure as recited in claim 7 wherein, said trigger means includes a pin engaging said contact, a spring urging said pin into engagement with said contact, and said protruding portion of said trigger means is provided for disengaging said pin against the action of said spring, thereby allowing extension of said contact to a position protruding from said housing.
Claim 12
Dependent Claim
108 words
A load break connector, comprising: a. a housing of dielectric material having an electrical conductor terminated therein; b. a male contact slidably mounted within said housing; c. connection means for connecting said contact to said electrical conductor; d. a pulling eye mounted externally on said load break connector in alignment with the longitudinal axis of said contact and comprising a pin and a loop of strand material pivotally mounted on said pin; and e. first and second mounting means positioned externally on said housing, said first mounting means being co-planar with and angularly displaced from said secmounting means, each of said mounting means adapted to receive said pin.
Claim 13
Dependent Claim
108 words
A load break connector, comprising: a. a housing of dielectric material having an electrical conductor terminated therein; b. a male contact slidably mounted within said housing; c. connection means for connecting said contact to said electrical conductor; d. a pulling eye mounted externally on said load break connector in alignment with the longitudinal axis of said contact and comprising a pin and a loop of strand material pivotally mounted on said pin; and e. first and second mounting means positioned externally on said housing, said first mounting means being co-planar with and angularly displaced from said secmounting means, each of said mounting means adapted to receive said pin.
