The optical-electrical connector according to any one of claim 10, wherein a cable groove (812) is formed in the straight sleeve (801) at a position between the two insertion holes (806), the cable groove (812) faces the central hole of the straight sleeve (801), a plurality of lower limiting convex inclined blocks (8121) are arranged at the bottom of the cable groove (812), a plurality of upper limiting convex inclined blocks (8044) corresponding to the lower limiting convex inclined blocks (8121) are arranged on the flip cover (804), and when the flip cover (804) is buckled on the straight sleeve (801), the upper limiting convex inclined blocks (8044) and the lower limiting convex inclined blocks (8121) compress the optical fibers placed in the cable groove (812).

12. The optical-electrical connector according to claim 11, wherein pre-positioning blocks (8122) are arranged on two sides of the cable trough (812), and the optical cable is placed in the cable trough (812) and then the pre-positioning blocks (8122) on the two sides contact the optical cable.

13. The optoelectronic connector of claim 12, wherein the receptacle (806) has a deformation groove (8062) on the inner side opposite to the positioning block (8122).

14. The optical-electrical connector according to claim 1, wherein the inner core assembly (805) comprises an optical-fiber ferrule (8051), an inner core (8052), an inner cover (8053) and a support spring (8054), the inner core (8052) is attached to the inner cover (8053), and an aperture is formed between the inner core (8052) and the inner cover (8053) for passing through an optical fiber, the support spring (8054) is sleeved on the inner core (8052) and the inner cover (8053) for applying pressure to the inner core (8052) and the inner cover (8053) to attach the inner core (8052) to the inner cover (8053), and one end of the optical-fiber ferrule (8051) is disposed between the inner core (8052) and the inner cover (8053).

15. The optical-electrical connector according to claim 14, wherein a cylindrical spring (813) is further arranged between the inner core assembly (805) and the straight sleeve (801), and the cylindrical spring (813) is used for applying pressure to the inner core assembly (805) to enable the ferrule (8051) to extend out of the straight sleeve (801).

16. A method of terminating a telecommunications cable, wherein the telecommunications cable is terminated using an opto-electrical connector according to any one of claims 1 to 15, the telecommunications cable being an optical fibre or an opto-electrical hybrid/composite cable.

17. The method of claim 16, wherein the optical fiber is terminated using an opto-electronic connector that is used as a fiber optic connector, wherein the terminating method is field or factory pre-terminated, and wherein the cable is accessed independently of the optical fiber in an application scenario requiring simultaneous access to the cable.
