Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
268 words
An electrical connector for connecting two leads together, comprising: a housing having a cylindrical opening formed therethrough, electrical insulating cylindrical means located in said opening, said electrical insulating cylindrical means being separate from said housing and removable from said opening, said electrical insulating cylindrical means having an opening formed therethrough, a metallic cylinder located in the opening of said insulating cylindrical means and having threads formed in its inside wall at opposite ends thereof, said metallic cylinder having an opening formed therethrough and having two contacts received through its opposite ends, each contact adapted to have an electrical lead connected thereto, said two contacts having shoulders extending outwardly therefrom, two holding means adapted to be fitted around said contacts and having threads formed on their outer surfaces and adapted to be threaded into opposite ends of said metallic cylinder for applying a holding force to said shoulders of said contacts for holding said contacts in said metallic cylinder, said housing having threads formed on its outer surface at opposite ends thereof, and two cup-shaped end caps, each having an inside cylindrical wall with threads formed therein, a first end with a large opening, and a rear wall at an opposite end with a small opening formed therethrough, said small opening of each end cap having a diameter less than the outside diameter of the ends of said housing and of a size sufficient to receive one of said leads, the size of said large opening of each end cap being sufficient to allow each end cap to be fitted around and threaded to one end of said housing.
Claim 2
Dependent Claim
268 words
An electrical connector for connecting two leads together, comprising: a housing having a cylindrical opening formed therethrough, electrical insulating cylindrical means located in said opening, said electrical insulating cylindrical means being separate from said housing and removable from said opening, said electrical insulating cylindrical means having an opening formed therethrough, a metallic cylinder located in the opening of said insulating cylindrical means and having threads formed in its inside wall at opposite ends thereof, said metallic cylinder having an opening formed therethrough and having two contacts received through its opposite ends, each contact adapted to have an electrical lead connected thereto, said two contacts having shoulders extending outwardly therefrom, two holding means adapted to be fitted around said contacts and having threads formed on their outer surfaces and adapted to be threaded into opposite ends of said metallic cylinder for applying a holding force to said shoulders of said contacts for holding said contacts in said metallic cylinder, said housing having threads formed on its outer surface at opposite ends thereof, and two cup-shaped end caps, each having an inside cylindrical wall with threads formed therein, a first end with a large opening, and a rear wall at an opposite end with a small opening formed therethrough, said small opening of each end cap having a diameter less than the outside diameter of the ends of said housing and of a size sufficient to receive one of said leads, the size of said large opening of each end cap being sufficient to allow each end cap to be fitted around and threaded to one end of said housing.
Claim 3
Dependent Claim
29 words
The electrical connector of claim 1 wherein: said contacts have flat ends, said holding means hold said contacts in said metallic cylinder with their flat ends in abutting relationship.
Claim 4
Dependent Claim
45 words
The connector of claim 1 comprising: means for securing said housing to a bulk head or the like with said housing extending through an opening formed in said bulk head and with opposite ends of said housing located on opposite sides of said bulk head.
Claim 5
Dependent Claim
113 words
The connector of claim 1 comprising: a relatively soft annular insulating member located in each of said cup-shaped end caps at its rear end and adapted to engage an end of said housing and an end of said one of said holding means when each end cap is fitted around and threaded to said housing, said housing having projections extending from its opposite ends to be embedded in said annular insulating members when said end caps are fitted around and threaded to said housing, said holding means having projections extending from their ends to be embedded in said annular insulating members when said end caps are fitted around and threaded to said housing.
Claim 6
Dependent Claim
24 words
The connector of claim 1 wherein: each of said holding means has a cylindrically shaped opening formed therethrough to be fitted around said contacts.
Claim 7
Dependent Claim
28 words
The connector of claim 5 wherein: said contacts have flat ends, said holding means hold said contacts in said metallic cylinder with their flat ends in abutting relationship.
Claim 8
Dependent Claim
113 words
The connector of claim 6 comprising: a relatively soft annular insulating member located in each of said cup-shaped end caps at its rear end and adapted to engage an end of said housing and an end of said one of said holding means when each end cap is fitted around and threaded to said housing, said housing having projections extending from its opposite ends to be embedded in said annular insulating members when said end caps are fitted around and threaded to said housing, said holding means having projections extending from their ends to be embedded in said annular insulating members when said end caps are fitted around and threaded to said housing.
Claim 9
Dependent Claim
15 words
The connector of claim 1 wherein: said contacts are fixedly connected to said electrical leads.
Claim 10
Dependent Claim
25 words
The electrical connector of claim 8 wherein: each of said holding means has a cylindrically shaped opening formed therethrough to be fitted around said contacts.
Claim 11
Dependent Claim
258 words
An electrical connector for connecting two leads together, comprising: a metallic housing having a cylindrical opening formed therethrough, electrical insulating cylindrical means located in said opening, said electrical insulating cylindrical means having an opening formed therethrough, a metallic cylinder located in the opening of said insulating cylindrical means and having threads formed in its inside wall at opposite ends thereof, said metallic cylinder having an opening formed therethrough and having two contacts received through its opposite ends, each contact adapted to have an electrical lead connected thereto, said two contacts having shoulders extending outwardly therefrom, two holding means having cylindrically-shaped openings formed therethrough to be fitted around said contacts and having threads formed on their outer surfaces and adapted to be threaded into opposite ends of said metallic cylinder for applying a holding force to said shoulders of said contacts for holding said contacts in said metallic cylinder, said housing having threads formed on its outer surface at opposite ends thereof, and two cup-shaped end caps, each having an inside cylindrical wall with threads formed therein, a first end with a large opening, and a rear wall at an opposite end with a small opening formed therethrough, said small opening of each end cap having a diameter less than the outside diameter of the ends of said housing and of a size sufficient to receive one of said leads, the size of said large opening of each end cap being sufficient to allow each end cap to be fitted around and threaded to one end of said housing.
