Description

A kind of SC fiber adapter

Technical field

The components and parts that the utility model communications optical cable field is suitable for specifically refer to a kind of SC fiber adapter.

Background technology

Usually couple together through its inner sleeve pipe by fiber adapter between the optical fiber; Fiber adapter; Claim again on the engineering that ring flange is the centering link of fiber active linker, material adopts metal and engineering plastics to process mostly, has extraordinary optical property and higher mechanical stability; Be widely used in fields such as Optical Distribution Frame, optical-fibre communications equipment, light instrument and meter, Fibre Optical Sensor, have highly stable and reliable performance.Yet existing fiber adapter all is made up of with the upper and lower inner bag that is plugged in the lower house the upper and lower casing of split design like the SC type, needs during use housing and inner bag orientation are connected; And use the ultrasonic soldering one, and the structural manufacturing process complicacy 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, frangible.

The utility model content

The utility model purpose is to solve the existing above-mentioned deficiency of SC fiber adapter, and a kind of SC fiber adapter of simple in structure, dependable performance is provided.

A kind of SC fiber adapter comprises upper shell, is connected the lower house of adapted with upper shell, and the housing that upper and lower casing constitutes is provided with the gathering sill that supplies external connector to peg graft; Be provided with upper inner-liner in the said upper shell; Be provided with bottom inner container in the lower house, said upper and lower inner bag is made up of right cylinder that has a through hole and the locator card that is located at the right cylinder both sides, and wherein said locator card is letter " H " shape; Said right cylinder is arranged on an end of locator card; Locator card is clamped on the inner walls with the upper and lower inner bag of fixing, also is provided with the boss that external application connects on the said housing, and the both sides of said housing also are provided with the clamping sheet of the external application frame of can pegging graft.

Be provided with a rib in the said housing, the inner bag that said upper and lower inner bag constitutes is provided with draw-in groove, and said rib injects in the draw-in groove inner bag is connected in the housing.

Said locator card is provided with the barb of projection.

The beneficial effect of the utility model: because the inner bag in the housing is provided with draw-in groove, inner walls is provided with the rib that is connected with the draw-in groove adapted, and said inner bag is made up of right cylinder that has a through hole and the locator card that is located at the right cylinder both sides; Wherein said locator card is letter " H " shape; Said right cylinder is arranged on an end of locator card, and locator card is clamped on the inner walls with the upper and lower inner bag of fixing, 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 as required a plurality of parallel, very convenient and swift.

Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Be to be understood that practical implementation instance described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Shown in Fig. 1～3, the utility model SC fiber adapter includes the housing 1 that disjunctor designs; Said housing 1 is made up of upper shell and the lower house that separate type matches, and the shell wall of said housing 1 is provided with the gathering sill 2 that play the guiding role when the connector that is for external application is pegged graft, and housing 1 middle part outside surface extends a boss 5 respectively to both sides; Boss 5 is provided with and can be fixed on the outer screw hole 4 that connects frame, and the both sides, bottom of housing 1 are provided with clamping sheet 6, and an end disjunctor of this clamping sheet 6 is located at the outside surface of housing 1; The adjustable inclined-plane of the unsettled one-tenth gradient of the other end; When receiving external force pressure, the gradient on inclined-plane disappears, and the two ends of clamping sheet 6 are parallel; When forces disappeared, an end of clamping sheet 6 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.

Combine ginseng shown in Figure 4 again; Be plugged with inner bag in the said housing 1; This inner bag divides upper inner-liner and bottom inner container, and 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, and locator card 7 is letter " H " shape; Said right cylinder 3 is arranged on an end of locator card 7, and locator card 7 is clamped on housing 1 inwall with the upper and lower inner bag of fixing.On said, bottom inner container is provided with draw-in groove 12 at the middle part, is provided with the rib 11 with draw-in groove 12 adapteds in the said housing, in draw-in groove that rib is pegged graft, is about to inner bag and is installed in the housing 1.Described right cylinder 3 is provided with the through hole 8 that supplies optical fiber to import, and is provided with the interior shoulder that guiding fiber passes through hole in this through hole 8.Described locator card 7 is that the center is symmetricly set on both sides with the right cylinder; Be provided with the triangle barb 9 of projection in the inside one side of locator card; When connector was plugged on the adapter under the guiding of gathering sill 2, barb 9 just can be stuck in the set groove in connector end so that connector is connected with adapter closely.

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.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
