Abstract

The utility model discloses an optical fiber adapter, comprising a shell with integral type design. The shell is provided inside with an upper inner liner and a lower inner liner, wherein, the two inner liners are composed of a cylinder with a thru hole and positioning blocks arranged on both sides of the cylinder; the cylinder of the upper inner liner is conjointly arranged inside the shell and the positioning block of the upper inner liner is conjointly arranged on the lower inner liner; the lower inner liner is embedded in the shell through mutually inserted wedge groove and rib. The utility model, which has an easier improved structure, is more convenient to operate and easier to manufacture by taking off the ultrasonic welding technology requested by the split type shell. With an integral type design, the shell is prevented from cracks and burrs, thereby providing the utility model with nicer appearance, more reliable quality and high shock strength. Moreover, the utility model avoids the easy-break of the split type shell and can be designed into parallel type based on requirements.

Description

Fiber adapter

Technical field

The utility model relates to the components and parts that a kind of optical-fibre communications field is used, and refers in particular to the fiber adapter that model is SC.

Background technology

Usually couple together by its inner sleeve pipe by fiber adapter between the optical fiber, fiber adapter (claiming ring flange on the engineering again) is the centering link of fiber active linker, material adopts metal and engineering plastics to make mostly, have extraordinary optical property and higher mechanical stability, fiber adapter can be divided into various models such as PC, SC, ST, LC, MTRJ usually, be widely used in fields such as Optical Distribution Frame (ODF), optical-fibre communications equipment, light instrument and meter, Fibre Optical Sensor, have highly stable and reliable performance.Yet existing fiber adapter, all form as the SC type by the upper and lower casing of split design and the upper and lower inner bag that is plugged in the lower house, need during use housing and inner bag orientation are connected, and use the ultrasonic soldering one, and the structural manufacturing process complexity of this split type adapter, assembling and use trouble, profile is ugly, of poor quality, be easy to occur crack and burr, a little less than the impact resistance, frangibility.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the defective of prior art and provides a kind of simple in structure, easy to manufacture, and is easy to use, reliable in quality, good looking appearance, fiber adapter excellent in cushion effect.

Technical matters of the present utility model is achieved through the following technical solutions:

A kind of fiber adapter, it comprises directed upper shell and the lower house that connects of split, the front of upper and lower casing is provided with the gathering sill of pegging graft for connector, be provided with upper inner-liner in the upper shell, be provided with bottom inner container in the lower house, upper and lower inner bag is made up of right cylinder that has through hole and the locator card that is located at the right cylinder both sides, directed up and down the connection, it is characterized in that described upper and lower casing is the housing of conjoined structure, the right cylinder disjunctor of upper inner-liner is arranged on enclosure interior, the locator card disjunctor design of upper inner-liner is on bottom inner container, and the bottom inner container socket connection is in housing; Described lower housing portion both sides are provided with the clamping sheet of the frame of can pegging graft.

The socket connection of described bottom inner container and housing is that the draw-in groove of bottom inner container and the rib in the housing plug.

Described housing is single structure or a plurality of conjoined structure in parallel.

Compared with prior art, the utility model has adopted the housing of disjunctor design, disjunctor is provided with the right cylinder of upper inner-liner in the housing, the locator card disjunctor of upper inner-liner is located on the bottom inner container, and bottom inner container is plugged in the housing through equipped mutually draw-in groove and rib, and the fiber adapter after the improvement is easy to use, good looking appearance, excellent in cushion effect, have simple in structure, easy to manufacture, the reliable quality advantage; Also can be designed to a plurality of parallel as required.

Embodiment

To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.

As Fig. 1～shown in Figure 11, fiber adapter, include the housing 1 of disjunctor design, this housing can be designed to single structure or a plurality of conjoined structure in parallel, the gathering sill 2 that the front 11 of housing play the guiding role when being provided with for the connector grafting, housing middle part outside surface extends a boss 5 respectively to both sides, boss is provided with the screw hole 4 that can be fixed on the frame, the lower part of frame both sides are provided with clamping sheet 6, one end disjunctor of this clamping sheet is located at the outside surface of housing 1, and the adjustable inclined-plane of the unsettled one-tenth gradient of the other end is when being subjected to external force pressure, gradient disappears, and the two ends of clamping sheet 6 maintain an equal level; When compressing power disappeared, an end of clamping sheet recovered gradient, and when on the distributing frame that is plugged on the communication frame, under the effect of clamping sheet 6, whole housing 1 just can firm being plugged on the frame like this.

Be plugged with inner bag in the housing, this inner bag divides upper inner-liner and bottom inner container, upper and lower inner bag is made up of right cylinder 3 and the locator card 7 that is located at the right cylinder both sides respectively, the right cylinder disjunctor of upper inner-liner is arranged on housing 1 inside, the locator card of upper inner-liner then disjunctor is arranged on the bottom inner container, bottom inner container is by being located at the middle part, being plugged in the housing with the rib 11 slotting draw-in groove 12 that matches in the housing, and described right cylinder is provided with the through hole 8 that imports for optical fiber, is provided with the interior shoulder that guiding fiber passes through hole in this through hole; Described locator card 7 is that the center is symmetricly set on both sides with the right cylinder, and two inside one sides of locator card are provided with triangular bump 9, and when connector was plugged on the adapter under the guiding of gathering sill 2, locator card 7 just can be stuck in the set groove in connector end.

The utility model adopts the housing and the inner bag of disjunctor design; make to make, use convenient; the various defectives of having avoided split type adapter in use to occur simultaneously; the every field that can be widely used in optical-fibre communications; when temporary transient time spent not, the housing two ends can be overlapped again and insert special-purpose dust cap with the protection inner structure.
