Abstract

An electrical connector adapted to be electrically connected with a cable includes a fixing assembly, an insulation body, and a conductive terminal overmolded in the insulation body. The fixing assembly includes a receiving portion extending in an axial direction of the electrical connector. An end of the cable is inserted into the receiving portion from a first end of the receiving portion. The insulation body extends from a second end of the receiving portion. The conductive terminal includes a mounting portion mounted in the insulation body and a contact portion extending out of the insulation body. The mounting portion is electrically connected with a conductor of the cable by a bolt member.

First claim

What is claimed is:

1. An electrical connector adapted to be electrically connected with a cable, comprising:
a fixing assembly including a main cylinder in which a receiving portion extending in an axial direction of the electrical connector is formed, an end of the cable is inserted into the receiving portion from a first end of the receiving portion;
an insulation body extending from a second end of the receiving portion;
a conductive terminal overmolded in the insulation body and including a mounting portion mounted in the insulation body and a contact portion extending out of the insulation body, the mounting portion is electrically connected with a conductor of the cable by a bolt member, the insulation body including a keyed portion extending substantially parallel and laterally adjacent to the contact portion for preventing the contact portion from being improperly inserted into a mating terminal of a mating connectors;
a first shielding sleeve extending from the second end of the receiving portion and sleeved over the insulation body;
a second shielding sleeve sleeved over a portion of the conductor of the cable, the first shielding sleeve extending to a portion of the second shielding sleeve from the insulation body;
a third shielding sleeve threaded to a second end of the main cylinder, through which the cable passes to be inserted into the main cylinder; and
a sealing sleeve sleeved over the cable, the sealing sleeve including a first portion having a first diameter and inserted into the first end of the receiving portion and a second portion having a second diameter larger than the first diameter and remaining outside the first end of the receiving portion, the second portion pressed between the first end of the main cylinder and an end of the third shielding sleeve so as to seal the first end of the receiving portion.

2. The electrical connector of claim 1 , wherein the mounting portion is a cylindrical structure extending axially, a side wall of the cylindrical structure has a through hole extending transversely through which the bolt member passes to abut against the conductor within the cylindrical structure.

3. The electrical connector of claim 1 , wherein the insulation body includes an insertion portion inserted into the receiving portion at the second end of the receiving portion and an extension integrally connected with the insertion portion and located outside the receiving portion.

4. The electrical connector of claim 3 , wherein the keyed portion extends from the extension in a direction of extension of the contact portion.

5. The electrical connector of claim 1 , further comprising a first shielding sleeve extending from the second end of the receiving portion and sleeved over the insulation body.

6. The electrical connector of claim 5 , wherein an end of the first shielding sleeve extending from the second end of the receiving portion has a plurality of resilient pieces folded onto the end the first shielding sleeve.

7. The electrical connector of claim 1 , wherein the fixing assembly includes a main cylinder in which the receiving portion is formed.

8. The electrical connector of claim 7 , wherein the fixing assembly includes a sealing ring mounted in a groove formed in an exterior surface of a first end of the main cylinder.

9. The electrical connector of claim 7 , wherein the fixing assembly includes a rotatable sleeve rotatably disposed over the main cylinder.

10. An electrical connector adapted to be electrically connected with a cable, comprising:
a fixing assembly including a main cylinder in which a receiving portion is formed and a rotatable sleeve rotatably disposed over the main cylinder, the receiving portion extending in an axial direction of the electrical connector, an end of the cable is inserted into the receiving portion from a first end of the receiving portion;
an insulation body extending from a second end of the receiving portion;
a conductive terminal overmolded in the insulation body and including a mounting portion mounted in the insulation body and a contact portion extending out of the insulation body, the mounting portion is electrically connected with a conductor of the cable by a bolt member; and
a mounting base mounted on and selectively lockable with the rotatable sleeve, the mounting base including a flange having a mounting hole, a receiving sleeve for receiving a portion of the fixing assembly and a locking member engaged with a mating locking member formed on the rotatable sleeve.

11. The electrical connector of claim 10 , further comprising:
a first shielding sleeve extending from the second end of the receiving portion and sleeved over the insulation body;
an elastic sleeve received in the main cylinder and sleeved over a portion of the cable; and
a second shielding sleeve sleeved over a portion of the conductor of the cable and a portion of the elastic sleeve, the first shielding sleeve extending to a portion of the second shielding sleeve from the insulation body.

12. The electrical connector of claim 11 , further comprising a third shielding sleeve threaded to a second end of the main cylinder, through which the cable passes to be inserted into the main cylinder.

13. The electrical connector of claim 12 , further comprising a sealing sleeve sleeved over the cable, the sealing sleeve including a first portion having a first diameter and inserted into the first end of the receiving portion and a second portion having a second diameter larger than the first diameter and remaining outside the first end of the receiving portion, the second portion pressed between the first end of the main cylinder and an end of the third shielding sleeve so as to seal the first end of the receiving portion.

14. The electrical connector of claim 13 , wherein the third shielding sleeve has a conical inner wall surface tapering outwardly and pressing the second portion of the sealing sleeve against an outer sheath of the cable.

15. The electrical connector of claim 10 , wherein the flange includes a plurality of mounting holes.

16. The electrical connector of claim 15 , wherein the locking member includes an axial protrusion axially protruding from the receiving sleeve and a locking protrusion radially protruding outwardly outside the axial protrusion.

17. The electrical connector of claim 16 , wherein a receiving groove radially recessed inwardly is formed outside of a first end of the main cylinder to receive the axial protrusion of the locking member, and an inner wall of the rotatable sleeve has a locking groove radially recessed outwardly and engaged with the locking projection to lock the fixing assembly and the mounting base together.

18. The electrical connector of claim 17 , wherein each of the locking protrusion and the locking groove has a substantially L-shape mated with each other to allow the fixing assembly to be locked with or separated from the mounting base by rotating the rotatable sleeve relative to the mounting base.

19. An electrical connector adapted to be electrically connected with a cable, comprising:
a fixing assembly including a main cylinder in which a receiving portion is formed and a rotatable sleeve rotatably disposed over the main cylinder, the receiving portion extending in an axial direction of the electrical connector, an end of the cable is inserted into the receiving portion from a first end of the receiving portion;
an insulation body extending from a second end of the receiving portion;
a first shielding sleeve extending from the second end of the
