Abstract

The present disclosure provides a tightly mountable optical fiber adapter which has a plurality of mating parts formed at front and rear sides of a base of a shell member thereof, and the base is combined with a base plate and two opposite side panels, each side panel is extended to form a first elastic part, and ends of second elastic parts are respectively outwardly bent and extended to form stop parts whose inner sides are bent towards the first elastic part and extended to form third elastic parts. While shell member is transversely mounted into an installing hole, first elastic parts are abutted and deformed to cross installing hole to clasp back side, second elastic parts are located in installing hole, so that shell member cooperating with mounting spring clip can be tightly fastened in installing hole, whereby the entire structure can be more securer.

First claim

What is claimed is:

1. An optical fiber adapter, comprising:
a shell member comprising a base defining a transverse cavity extending through the base, the base adapted to receive optical fiber connectors; and
a spring clip disposed at the outside of the base and cooperating with the shell member to transversely mount into an installing hole of a panel,
wherein the spring clip comprises a base plate having two opposite side panels formed at two opposite sides thereof, each side panel defines a first elastic part forwardly obliquely extended therefrom and configured to cross the installing hole for clasping a back side of the panel while the shell member is mounted, and each of the side panels has a front part disposed adjacent the first elastic part and a second elastic part extended therefrom in the same direction and configured to be located in the installing hole, and an end of the second elastic part is respectively outwardly bent and extended to form a stop part, each stop part extends towards the first elastic part to form a third elastic part for abutting with a front side of the panel.

2. The optical fiber adapter according to claim 1 , wherein the base of the shell member has wing parts protruded at two opposite sides of a central portion thereof, the base further defines a recessed part formed at a bottom wall and two lateral walls thereof after the wing parts for combining with the spring clip, and the stop parts on the two side panels of said spring clip are stopped on said wing parts in a flat state.

3. The optical fiber adapter according to claim 2 , wherein the base of the shell member is constructed of a front shell member and a rear shell member, a plurality of lips are respectively protruded from two sides of a junction between the front shell member and the rear shell member, and each two lips are combined to form the wing parts.

4. The optical fiber adapter according to claim 1 , wherein a compartment wall is formed at a central portion of the cavity between each of two mating parts of the shell member, and the compartment wall defines two mounting parts having hollow structures, and a pipe is fastened in the two mounting parts.

5. The optical fiber adapter according to claim 1 , wherein the base of the shell member defines recessed parts respectively disposed at a bottom wall and two lateral walls of a rear end thereof, and a fastening groove is formed at each of the recessed parts on the bottom wall of the base for mounting the base plate of the spring clip, and two sides of said fastening groove are respectively upwardly extended to two lateral walls of the base to form mounting grooves for receiving the side panel and fastening the spring clip in the recessed parts.

6. The optical fiber adapter according to claim 5 , wherein lower parts of the mounting grooves of the recessed part of the shell member define stop parts opposite inwardly bent and formed adjacent to the fastening grooves, arms are respectively formed at lower parts of the two side panels of the spring clip and adjacent to the base plate, and each of the arms has front and back sides which are adjacent to the side panel and opposite inwardly bent to form jointing surfaces for clasping the stop parts for fastening.

7. The optical fiber adapter according to claim 1 , wherein a central part of the front side of the side panel of the spring clip defines a hole therethrough and extended near the rear side of the side panel, and the first elastic part which is forwardly obliquely extended from the inner edge of the hole defines a supporting surface at an external surface thereof, a free end of the first elastic part is bent towards the hole and extended to form a clasping end located in parallel with the side panel and configured to clasp a peripheral surface of the installing hole of the panel, and a predetermined distance smaller or equal to the thickness of the predetermined panel is formed between the clasping end of the first elastic part and a free end of the third elastic part.

8. The optical fiber adapter according to claim 1 , wherein external surfaces of the second elastic parts of the side panels of the spring clip are outwardly extended to form first pushing surfaces configured to abut against an inner sidewall of the installing hole of the panel with elastic deformation.

9. The optical fiber adapter according to claim 1 , wherein the third elastic parts at the side panels of the spring clip respectively define second pushing surfaces formed on external surfaces thereof towards the first elastic part and configured to abut with the front side of the panel with elastic deformation.

10. The optical fiber adapter according to claim 1 , wherein said spring clip is a U-shaped metal sheet having two symmetrical side-walls and made of elastic steel material integrally.

11. An optical fiber adapter, comprising:
a shell member comprising a base defining a transverse cavity extending through the base, the base adapted to receive optical fiber connectors; and
a spring clip disposed at the outside of the base and cooperating with the shell member to transversely mount into an installing hole of a panel,
wherein the spring clip comprises a base plate having two opposite side panels formed at two opposite sides thereof, each side panel defines a first elastic part forwardly obliquely extended therefrom and configured to cross the installing hole for clasping a back side of the panel while the shell member is mounted, and each of said side panels has front parts disposed respectively above and below the first elastic part and have second elastic parts extended therefrom in the same direction and configured to be located in the installing hole, and ends of the second elastic parts are respectively outwardly bent and extended to form stop parts, each two stop parts are bent opposite to each other and extended towards said first elastic part to form third elastic parts for abutting with a front side of said predetermined panel.

12. The optical fiber adapter according to claim 11 , wherein the base of the shell member has wing parts protruded at two opposite sides of a central portion thereof, the base further defines a recessed part formed at a bottom wall and two lateral walls thereof after the wing parts for combining with the spring clip, and the stop parts on the two side panels of the spring clip are stopped on the wing parts in a flat state.

13. The optical fiber adapter according to claim 2 , wherein the base of the shell member is constructed of a front shell member and a rear shell member, a plurality of lips are respectively protruded from two sides of a junction between the front shell member and the rear shell member, and each two lips are combined to form the wing parts.

14. The optical fiber adapter according to claim 11 , wherein a compartment wall is formed at a central portion of the cavity between each of two mating parts of the shell member, and the compartment wall defines two mounting parts having hollow structures, and a pipe is fastened in the two mounting parts.

15. The optical fiber adapter according to claim 11 , wherein the base of the shell member defines recessed parts respectively disposed at a bottom wall and two lateral walls of a rear end thereof, and a fastening groove is formed at each of the recessed parts on the bottom wall of the base for mounting the base plate of the spring clip, and two sides of the fastening groove are respectively upwardly extended to two lateral walls of the base to form mounting grooves for receiving the side panel and fastening the spring clip in the recessed parts.
