Abstract

A cable connector includes socket body, terminal set, telescopic sleeve, elastic element, fastening member, locking element and cable sleeved with positioning ring piece and insulating sleeve. The socket body has screw hole on middle, plug-in portion and fixed portion located at two sides, and locking hole located on fixed portion. A glue seat is formed on the soldering area between the soldering ends of the plug-in terminals of the terminal set and the core wires of the cable. A fixing sleeve is movably joined to terminal block and then fitted to the outside of glue seat. The outer diameter of plug-in portion of socket body is sequentially sleeved with elastic element and movable telescopic sleeve. The socket body and terminal block and socket body and cable can be fixed together by fastening member and locking element in combination with screw hole and locking hole of socket body.

First claim

What the invention claimed is:

1. A cable connector, comprising a socket body, a terminal set, a telescopic sleeve, an elastic element, a fastening member, a locking element and a cable sleeved with a positioning ring piece and an insulating sleeve, wherein:
said socket body is a hollow pipe, comprising a plug-in portion located on one side, a fixed portion located on an opposite side, a locking hole located on a rear side of an outer diameter surface of said fixed portion, a plug-in space defined in said plug-in portion and a fixed space defined in said fixed portion in communication with said plug-in space;
said terminal set comprises a terminal block, a plurality of plug-in terminals, a glue seat and a fixing sleeve, said terminal block having a butt end located in said plug-in space of said socket body;
said plug-in terminals being set in said terminal block, said plug-in terminals each having a soldering end exposed on the outside of said terminal block and respectively soldered with one respective core wire of said cable, said glue seat being provided at the soldering area between said core wires of said cable and said soldering ends of said plug-in terminals, said fixing sleeve being movably joined to one side of said terminal block and fitted to the outside of said glue seat;
said telescopic sleeve is movably attached onto said socket body, said telescopic sleeve having a limiting space formed therein;
said elastic element is located between said limiting space of said telescopic sleeve and the outer diameter of said plug-in portion of said socket body;
said locking element is locked into said locking hole of said fixed portion of said socket body and pressed against said positioning ring piece of said cable to form a positioning, so that said insulating sleeve covers said fixed portion and said locking element.

2. The cable connector as claimed in claim 1 , wherein said socket body further comprises a base portion connected between said plug-in portion and said fixed portion and a stepped stop portion turned downward and formed between said base portion and said plug-in portion; said telescopic sleeve is provided with a protruding stop portion at the inner diameter of said limiting space; said elastic element has two ends thereof respectively abutted between said stepped stop portion and said protruding stop portion.

3. The cable connector as claimed in claim 2 , wherein said socket body further comprises said base portion connected between said plug-in portion and said fixed portion and a screw hole located on said base portion; said terminal block is integrally formed with a metal fixing ring on the outer diameter of an opposite end thereof remote from said butt end; said fastening member is locked into said screw hole of said base portion of said socket body and then pressed against said metal fixing ring to form a positioning.

4. The cable connector as claimed in claim 1 , wherein said terminal block further comprises a plurality of accommodating holes, and said plug-in terminals are respectively set in said accommodating holes.

5. The cable connector as claimed in claim 1 , wherein said terminal block further comprises a stepped surface formed at the outer diameter of said butt end.

6. The cable connector as claimed in claim 1 , wherein the outer diameter of said plug-in portion of said socket body is provided with a plurality of guide blocks equidistant in the axial direction.

7. The cable connector as claimed in claim 1 , wherein said plug-in portion of said socket body is provided with button holes at two sides.

8. The cable connector as claimed in claim 1 , wherein said glue seat is fixed to said soldering area with an insulating glue by molding.

9. The cable connector as claimed in claim 1 , wherein said socket body further comprises a guide rail extending axially and protruded in said fixed space; said terminal block further comprises a guide groove extending axially on a bottom thereof for sliding on said guide rail of said socket body.

10. The cable connector as claimed in claim 1 , wherein said terminal block further comprises a guide groove extending axially on a bottom thereof, a bearing surface located on an outer diameter surface edge thereof remote from said butt end and a snap groove formed in said guide groove; said fixing sleeve comprises a resisting portion abutted against said bearing surface of said terminal block, and a hook snapped into said snap groove of said guide groove.

11. The cable connector as claimed in claim 1 , wherein said positioning ring piece has a section; said locking element locks into said locking hole of said fixed portion of said socket body and then presses against said section of said positioning ring piece to form positioning.

12. The cable connector as claimed in claim 2 , wherein said socket body further comprises said base portion connected between said plug-in portion and said fixed portion and a screw hole located on said base portion; the outer diameter of said terminal block is molded in one piece with a metal fixing ring; said fastening member is locked into said screw hole of said socket body and then pressed against said metal fixing ring of said terminal block to form a positioning.

13. The cable connector as claimed in claim 1 , wherein said telescopic sleeve is provided with a through hole at an outer diameter surface thereof for said fastening member to pass through and lock into said socket body.

14. A method of assembling a cable connector comprising a socket body, a terminal set, a telescopic sleeve, an elastic element, a fastening member, a locking element and a cable sleeved with a positioning ring piece and an insulating sleeve, the method comprising the steps of:
passing a plurality of plug-in terminals of said terminal set through respective accommodating holes of a terminal block of said terminal set to expose respective soldering ends of said plug-in terminals on the outside of said terminal block;
setting said positioning ring piece and said insulating sleeve on the outer diameter of said cable in sequence, and squeezing said positioning ring piece on said cable;
soldering respective core wires of said cable to the respective said soldering ends of said plug-in terminals;
attaching a fixing sleeve to one side of said terminal block and gluing the soldering area between said core wires of said cable and said soldering ends of said plug-in terminals with insulating glue to form a glue seat, and then placing said elastic element on the outer diameter of a limiting space of said telescopic sleeve and a plug-in portion of said socket body and positioning a rear side of said telescopic sleeve at the outer diameter of said socket body to let two ends of said elastic element be respectively pressed against the outer diameter of said socket body and the inner diameter of said telescopic sleeve;
pushing the assembled said terminal set and said cable into a fixed space of a fixed portion of said socket body to let the front butt end of said terminal block of said terminal set be located in the leading edge of a plug-in space of said socket body;
locking said fastening member into a screw hole of said socket body to fix said terminal block, so that said telescopic sleeve is in a movable and retractable state by the elastic support of said elastic element outside said plug-in portion of said socket body; and
