Abstract

The present disclosure provides a stackable optical fiber adapter including shell members, a base with mating parts formed at front and rear sides thereof, and an accommodating cavity being transversely formed therein and communicated with the two opposite mating parts. One positioning part and wedged-jointing part are at two adjacent bases, and one clasping block and position-limiting groove are on the positioning part and the wedged-jointing part. By such a way, each two adjacent bases can be stacked, arranged or formed by a modularized manner, so that more shell members can be installed on a panel. The adapter can be easy to design the corresponding mold, the mating parts of each shell member is constant, and necessary to develop different molds, so the manufacturing process and the mold can be simplified, and the optical fiber adapter of the present disclosure can have stable structure and low cost, and further facilitate mass production.

First claim

What the invention claimed is:

1. A stackable optical fiber adapter, comprising:
a plurality of shell members, and bases of the plurality of shell members defining a plurality of mating parts formed at front and rear opposite sides thereof, and each two opposite mating parts having an accommodating cavity transversely communicated therethrough to insert with predetermined optical fiber connectors, and
at least one positioning part and a wedged-jointing part on each lateral side of adjacent bases of adjacent shell members,
said positioning part and said wedged-jointing part respectively having a dovetail-shaped clasping block and a position-limiting groove which can be mounted and fastened with each other to make the plurality of shell members be modularized as an integral structure,
said position-limiting groove of said wedged-jointing part defining a sliding slot with a step-like stop wall outwardly formed at a bottom opening of said sliding slot to abut with an end surface of a clasping block of a positioning part of an adjacent shell member positioned within said sliding slot and facilitate lateral sides of two adjacent bases to be flush with each other.

2. The stackable optical fiber adapter according to claim 1 , wherein said shell member defines at least one protruding wing plate disposed at one side or two opposite sides of a center portion of said base thereof.

3. The stackable optical fiber adapter according to claim 1 , wherein said shell member defines a compartment wall formed at a center portion of said accommodating cavity between each two mating parts, and said compartment wall defines a hollow mounting part transversely extended toward said accommodating cavity and having an insertion channel, and a pipe is fastened in said insertion channel, a fastening part is fastened in said accommodating cavity at other side of said compartment wall opposite to said mounting part, and a fastening channel is formed inside said fastening part to be inserted by an end of said pipe projected out of said compartment wall.

4. The stackable optical fiber adapter according to claim 1 , wherein said base of said shell member defines a plurality of positioning parts and corresponding wedged-jointing parts transversely disposed at said accommodating cavities of top and bottom sides thereof and adjacent to said mating parts thereof, and said positioning parts of said shell member can be mounted and fastened with said wedged-jointing parts of other shell member to make said plurality of shell members be vertically stacked as an integral assembly by a modularized manner.

5. The stackable optical fiber adapter according to claim 1 , wherein said base of said shell member defines a plurality of positioning parts and corresponding wedged-jointing parts vertically disposed respectively at left and right sides thereof and near said center portion thereof, said positioning parts of said shell member and said wedged-jointing parts of other shell member can be mounted with each other to make the plurality of shell members be horizontally arranged in parallel to form as an integral assembly by a modularized manner.

6. The stackable optical fiber adapter according to claim 1 , wherein said base of said shell member defines a plurality of positioning parts and corresponding wedged-jointing parts vertically or transversely disposed respectively at each two adjacent lateral sides thereof, and said positioning parts of said shell member and said wedged-jointing parts of said other shell member can be mounted with each other to make the plurality of shell members be assembled as an integral array structure by a modularized manner.

7. An optical fiber adapter, comprising:
a shell member with a base, said base comprising:
a plurality of mating parts formed at front and rear opposite sides of said base, each two opposite mating parts having an accommodating cavity transversely communicated therethrough to insert with predetermined optical fiber connectors; and
at least one positioning part with a dovetail-shaped clasping block protruding from said base and at least one wedged-jointing part with a position-limiting groove recessed in said base, said position-limiting groove defined for another dovetail-shaped clasping block of an adjacent shell member to slide therewithin;

wherein said position-limiting groove comprises a sliding slot with a step-like stop wall outwardly formed at a bottom opening of said sliding slot to abut with an end surface of another dovetail-shaped clasping block of the adjacent shell member positioned within said sliding slot and facilitate lateral sides of two adjacent bases to be flush with each other.

8. The optical fiber adapter according to claim 7 , wherein said shell member defines at least one protruding wing plate disposed at one side or two opposite sides of a center portion of said base thereof.

9. The optical fiber adapter according to claim 7 , wherein said shell member defines a compartment wall formed at a center portion of said accommodating cavity between each two mating parts, and said compartment wall defines a hollow mounting part transversely extended toward said accommodating cavity and having an insertion channel.

10. The optical fiber adapter according to claim 9 , furthering comprising:
a pipe fastened in said insertion channel;
a fastening part fastened in said accommodating cavity at a side of said compartment wall opposite to said hollow mounting part; and
a fastening channel formed inside said fastening part to be inserted by an end of said pipe projected out of said compartment wall.
