专利汇可以提供Method and connector having conductive elastomeric material encircled by a continuous layer of insulation in intimate contact therewith专利检索，专利查询，专利分析的服务。并且An electrical connector comprising: an explosive charge and a plurality of radially movable electrically conducting jaws contained within an electrically conducting housing. The housing is completely encircled by and bonded to a continuous insulation layer which is impervious to moisture. The bared conductor ends of two lengths of high voltage electrical cable are inserted through the insulation layer, between the jaws and in engagement with electrical contact rivets protruding from the propellant charge. The conductor of one of the cable lengths is grounded to its outer shielding. The second length of cable is provided with a current source impressed between its conductor and cable shielding. As a result, an electrical path for the current source is provided through the contact rivets and through the propellant charge. The charge is thereby detonated to propel the jaws into radial engagement on the cable conductors and in mechanical and electrical contact with the housing. The insulation layer remains undisturbed and bonded to the housing. This advantageously allows detonation of the propellant charge without entry through the insulation layer, or, in the alternative, requiring a multiple piece insulation layer which must be assembled over the cable subsequent to termination.，下面是Method and connector having conductive elastomeric material encircled by a continuous layer of insulation in intimate contact therewith专利的具体信息内容。

权利要求

1. An electrical connector, comprising: an electrically conducting housing, a propellant charge in said housing, two pistons slidably mounted in said housing and having electrical contacts thereon electrically engaging said charge, a group of radially movable electrically conducting jaws mechanically and electrically connected to a corresponding piston, an electrical contact through each piston connected to said charge, each electrical contact being encircled by a corresponding group of said jaws, said housing having an opening in communication with each corresponding contact and in communication with a space defined between each corresponding group of said jaws, a voltage distributing means encircling said housing, and a continuous unseamed layer of insulation completely encircling said housing and said distribution means, said layer of insulation extending generally in cylindrical fashion beyond each opening of said housing, said layer of insulation being formed of a resiliently radially compressible sealant material having generally central openings therethrough and in communication with corresponding openings of said housing, whereby said layer of insulation will compressibly encircle and form moisture impervious seals around corresponding end portions of electrical cables when inserted into said openings of said layer of insulation, and whereby said electrical cables when further inserted into corresponding openings of said housing will engage said contacts and provide a circuit path for a voltage applied through said electrical cables and through said propellant charge, thereby discharging said propellant charge to force said pistons and said groups of jaws slidably along said tapered housing and further to force said groups of jaws radially inwardly into electrical engagement on said electrical cables.

2. The structure as recited in claim 1, wherein said distributing means includes a molded seamless layer of electrically conducting elastomeric material bonded in intimate contact with said housing, said layer of electrically conducting elastomeric material being provided with terminal end portions adjacent to corresponding openings of said housing, thereby assuring distribution of voltage from said housing throughout the entire mass of said layer of electrically conducting elastomeric material, said layer of insulation material substantially encircling and being bonded to and in intimate contact with said layer of electrically conducting elastomeric material, and a tough layer of conducting material provided over said layer of insulation material forming an outer moisture impervious jacket for said connector.

3. A method of terminating an electrical cable, comprising the steps of: providing a propellant charge within an electrically conducting housing, providing a group of spaced apart and radially movable conducting jaws in said housing, providing an electrical contact disposed between said jaws and electrically connecting said conducting jaws with said charge, encircling said housing with voltage distribution means, encircling said voltage distributing means with a molded seamless continuous layer of electrical insulation material in intimate encircling contact with said housing, inserting an electrically conducting cable between said jaws and in contact with said electrical contact, said molded seamless continuous layer of electrical insulation material being received in intimate encircling contact around said cable to form a moisture impervious seal therearound, and applying an electrical charge across said propellant charge to detonate said propellant charge and to propel said jaws into radial wedged relationship between and in electrical contact with said cable and said housing to result in a completed electrical and mechanical connection.

4. The method as recited in claim 3, wherein, the step of applying an electrical charge across said propellant charge includes the step of: applying an electrical charge on said cable and electrically grounding said propellant charge to a reference potential, thereby causing detonation of said propellant charge.

5. An electrical connector, comprising: an electrically conducting housing generally of cylindrical form having two openings therein, a propellant charge generally centrally within said housing, two pistons slidably mounted in said housing, each of said pistons having an electrical contact thereon engaging said propellant charge, a group of spaced apart electrically conducting jaws in contact with a corresponding piston and defining a space therebetween, each group of said jaws encircling a corresponding contact received in the space defined therebetween, a voltage distributing means adjacent said two openings of said housing and in contact with said housing, a generally cylindrical unseamed layer of insulation material encircling said housing and said voltage distributing means, said layer of insulation material extending beyond the openings of said housing to define moisture impervious seals adjacent the openings of said housing, each of said seals having an opening centrally thereof in communication with the space defined between a corresponding group of said jaws, and an outer shell of metal encircling said layer of insulation material and defining a tough and moisture impervious jacket, whereby ends of electrical cables when inserted through the openings of said insulation material will be radially compressed and encircled by said insulation material to form moisture impervious seals encircling said electrical cables, and whereby said ends of electrical cables when inserted between corresponding groups of said jaws will engage corresponding electrical contacts and provide a circuit path through said electrical cables and through said propellant charge, whereby said propellant charge will be detonated to force said pistons slidably within said housing and further to force said groups of jaws both slidably within said housing and radially inwardly into electrical engagement on said electrical cables.

6. The structure as recited in claim 5, wherein said distributing means includes a molded seamless continuous layer of electrically conducting elastomeric material bonded to and in intimate contact with and encircling said housing, said electrically conducting elastomeric material having generally flared end portions adjacent to said openings of said housing to assure distribution of voltage from said housing throughout the entire mass of said continuous layer of electrically conducting elastomeric material, said layer of insulation material being bonded to and encircling said layer of electrically conducting elastomeric material.
