Abstract

A terminal connector assembly for connecting coaxial cables to a selected device, such as, a cable television is made up of an adaptor and socket in press-fit relation to one another with an end connector at one end of the adaptor having endless sealing rings along an inner wall surface of an outer sleeve of the connector and spaced serrations or gripping edges along an external wall surface of an inner sleeve so that when the cable is inserted into the end connector with the outer conductor and jacket in the annular space between the inner and outer sleeves, the outer sleeve can be crimped inwardly to cause the ribs to advance into uniform sealed engagement with the jacket and the gripping edges will cooperate in resisting any tendency of the cable to separate from the end connector. The socket portion either can be directly attached to a cable television terminal or wall plate or may include a second end connector for crimped connection to another coaxial cable extending from the terminal or wall plate.

Claims

1. A terminal connector assembly for connecting an end of a coaxial cable to a terminal wherein said cable has radially inner and outer conductors separated by an annular dielectric, a tubular jacket encasing said outer conductor and a portion of said outer conductor being exposed at the end of said cable, said assembly comprising:

(a) an end connector having radially inner and outer spaced coaxial sleeves, said inner sleeve being sized for insertion of said inner conductor and said annular dielectric therein, said outer sleeve being sized for insertion of said conductor and said jacket through one end of said connector between said inner and outer sleeves;

(b) at least one rib extending circumferentially around an inner wall surface portion adjacent to the one end of said outer sleeve, said rib engaging an external surface of said jacket when said outer sleeve is deformed radially inwardly until said rib effects sealed engagement with said jacket;

(c) a terminal connector having a hollow generally cylindrical portion, an adaptor at one end of said cylindrical portion, a conductor member extending concentrically within said cylindrical portion and adaptor including contact portions at opposite ends thereof; and

(d) said outer sleeve including a complementary connecting end portion to said adaptor connecting end portion for positively connecting said outer sleeve to said adaptor, said inner conductor electrically connected to one of said contact portions when said outer sleeve is positively connected to said adaptor.

2. A connector assembly according to claim 1, said adaptor connecting end portion and said outer sleeve connecting end portion having complementary threaded end portions.

3. A connector assembly according to claim 1, said inner conductor defined by a pin insertable into said one contact portion.

4. A connector assembly according to claim 1, said hollow generally cylindrical portion including a socket portion, and an adaptor extending at right angles to said socket portion.

5. A connector assembly according to claim 4, said terminal connector including a pin extending from said terminal, and said conductor member extending at right angles to said pin with another of said contact portions engaging said pin.

6. A terminal connector assembly for connecting an end of a coaxial cable to a terminal wherein said cable has radially inner and outer conductors separated by an annular dielectric, a tubular jacket encasing said outer conductor and a portion of said outer conductor being exposed at the end of said cable, said assembly comprising:

(a) an end connector having radially inner and outer spaced coaxial sleeves, said inner sleeve being sized for insertion of said inner conductor and said annular dielectric therein, said outer sleeve being sized for insertion of said conductor and said jacket through one end of said connector between said inner and outer sleeves;

(b) at least one endless sealing ring on an inner surface of said outer sleeve deformable into a portion of said jacket, and said inner sleeve having external projections along an external wall surface portion thereof adjacent to the one end thereof;

(c) a terminal connector having a hollow generally cylindrical portion, an adaptor at one end of said cylindrical portion, a conductor member extending concentrically within said cylindrical portion and adaptor including contact portions at opposite ends thereof; and

(d) said outer sleeve including a complementary connecting end portion to said adaptor connecting end portion for positively connecting said outer sleeve to said adaptor, said inner conductor electrically connected to one of said contact portions when said outer sleeve is positively connected to said adaptor.

7. A connector assembly according to claim 6, there being a plurality of axially spaced sealing rings on said inner wall surface portion of said outer sleeve, said outer sleeve having an external surface portion of substantially uniform diameter throughout.

8. A connector assembly according to claim 7, said rings having intervening spaces therebetween with rounded surfaces of generally circular cross-sectional configuration.

9. A terminal connector assembly for connecting an end of a coaxial cable to a terminal wherein said cable and said terminal each has radially inner and outer, generally cylindrical conductors separated by an annular dielectric, a tubular jacket encasing said outer conductor and a portion of said outer conductor being exposed at the end of each said cable, said assembly comprising:

(a) an end connector for each said cable having radially inner and outer spaced coaxial sleeves, said inner sleeve being sized for insertion of said inner conductor and said annular dielectric therein, said outer sleeve being sized for insertion of said conductor and said jacket through one end of each said connector between said inner and outer sleeves;

(b) at least one endless circular rib extending circumferentially around an inner wall surface portion of each said outer sleeve adjacent to the one end of said outer sleeve, said rib engaging an external surface of said jacket when said cable is fully inserted into said connector and said outer sleeve is deformed radially inwardly until said rib effects sealed engagement with said jacket;

(c) a terminal connector having a generally cylindrical socket portion, an adaptor at one end of said socket portion, a conductor extending concentrically through said socket portion and adaptor including spring-loaded contact portions at opposite ends; and

(d) each said outer sleeve including a complementary connecting end portion to one end of said adaptor and said socket portion for positively connecting each of said outer sleeves to one of said adaptor and said socket portion, said inner conductors electrically connected to said contact portions when said outer sleeves are positively connected to said adaptor and said socket portion.

10. A terminal connector assembly according to claim 9, said complementary connecting end portions defined by complementary threaded end portions.

11. A terminal conductor assembly portion according to claim 9, said inner sleeve being substantially coextensive with said outer sleeve.

12. A terminal conductor assembly according to claim 9, said adaptor being inserted in press-fit relation to one end of said socket portion.

13. A terminal conductor assembly according to claim 12, said socket portion having an expandable sleeve end portion for press-fit insertion of one end of said adaptor.

14. A terminal conductor assembly according to claim 9, said terminal connector conductor including a conductor pin inserted into a complementary sleeve portion when said adaptor is inserted in press-fit relation to said socket portion.
