## Abstract

The present invention provides an optical connector comprising an optical receptacle, a coupling terminal, and a coil structure, wherein the optical receptacle has an accommodation space and a positioning structure, the coupling terminal is arranged into the accommodation space, and the coil structure has a first fixing coil and an elastic coil wherein the coupling terminal is inserted into the elastic coil and the first fixing coil is arranged onto the positioning structure.

## Claims

### Claim 1

An optical connector, comprising:
a housing, having a positioning structure, an accommodation space disposed into the housing;
a coupling terminal, disposed into the accommodation space; and
a coil structure, having an elastic coil and a first fixing coil, the elastic coil sleeved on the coupling terminal, and the first fixing coil sleeved on the positioning structure,
wherein a second fixing coil is connected between the elastic coil and the first fixing coil, and is fixed with the coupling terminal.

### Claim 2 (depends on 1)

The optical connector of claim 1, wherein outer diameter of the first fixing coil is larger than outer diameter of the elastic coil.

### Claim 3 (depends on 1)

The optical connector of claim 1, wherein the positioning structure is disposed into the accommodation space, and has an accommodation groove and a plurality of leaning structures, the accommodation groove is disposed on a wall surface of the accommodation space, the plurality of leaning structures are connected to a wall surface of the housing and correspond to the accommodation groove, and the first fixing coil is disposed into the accommodation groove and restrained by the plurality of leaning structures.

### Claim 4 (depends on 1)

The optical connector of claim 1, wherein outer diameter of the second fixing coil is equal to outer diameter of the elastic coil, and is smaller than outer diameter of the first fixing coil.

### Claim 5 (depends on 1)

The optical connector of claim 1, wherein the positioning structure is disposed on an end of the housing, and has an accommodation groove and a leaning structure connected to a side of the accommodation groove, the first fixing coil is disposed into the accommodation groove, and an end section of the first fixing coil is leaned against the positioning structure.

### Claim 6 (depends on 1)

The optical connector of claim 1, wherein outer diameter of the second fixing coil is equal to outer diameter of the elastic coil, and is smaller than outer diameter of the first fixing coil.

### Claim 7 (depends on 5)

The optical connector of claim 5, wherein the accommodation groove has an opening, a positioning groove is disposed on a side of the opening.

### Claim 8 (depends on 7)

The optical connector of claim 7, wherein the first fixing coil has an extending section and at least one winding section, the extending section extends from the accommodation space to the opening of the accommodation groove, an end of the at least one winding section is connected to the extending section, another end of the at least one winding section is connected to the end section, and the at least one winding section is wound on the accommodation groove, the end section extends toward the positioning structure and is leaned against the positioning groove.
