Abstract

An improved fiber connector dust prevention cap is used to prevent dust for fiber connectors. The utility model additionally connects a block of connection board on the upper end of the original dust prevention cap, the connection board is covered on the upper end of the dust prevention cap and drags a connection strip with the shape like a tail, the connection strip passes through the hole arranged in an open manner on the edge side of the upper part of the dust prevention cap, and the end head of the connection strip is provided with a connection hole which can be fixedly provided with the fiber connector. The center of the connection board is arranged in an open manner with a hole passing through a fiber insertion core dust prevention cap in order to arranged the fiber insertion core, and the center of the upper part of the dust cap body is additionally provided with a column shaped convex head, and the convex head can be used to insert the fiber insertion core dust prevention cap. The utility model can prevent loss of itself and the fiber insertion core prevention cap.

Description

Improved joints of optical fibre dust cap

Technical field

The utility model relates to the components and parts in the optical communications field, especially relates to the dust cap device of the joints of optical fibre.

Background technology

Need components and parts in the transmission channel of light optical fiber is coupled together, these class components and parts claim adapter again, are commonly called as flange, are fixed in during use on the coil holder; In the stringing terminal, the termination of the joints of optical fibre need be covered with dust cap, in case fall into dust; When this terminal again during wiring, must remove dust cap; The dust cap and the joints of optical fibre that use are to be provided with separately separately at present, and are disjunct mutually, and therefore the dust cap that takes off when rewiring is easy to lose.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, a kind of improved joints of optical fibre dust cap to be provided, the dust cap and the joints of optical fibre being connected together, unlikely losing; Another purpose of the present utility model is that the fiber stub dust cap that takes off also can be with wiring the time is also put into this dust cap, to prevent losing of fiber stub dust cap.

For achieving the above object, the technical solution of the utility model is such: a kind of improved joints of optical fibre dust cap, be at web joint of the upper end of former dust cap adjunction, this web joint is covered in the dust cap upper end, and drag a connecting band just as tail, this connecting band passes in the hole that dust cap top avris offers, and the termination of connecting band is provided with connecting hole, can fix with the joints of optical fibre; In order to place the fiber stub dust cap, offer a hole of passing through the fiber stub dust cap at the web joint center, and add a columniform plush copper, this plush copper fiber stub dust cap that can be used to peg graft in dust cap body central upper portion.

Owing to adopted technique scheme, a kind of improved joints of optical fibre dust cap of the present utility model connects together by the web joint and the joints of optical fibre, can not lose during wiring; The plush copper of the She Zhiing fiber stub dust cap that can be used to peg graft is avoided losing of fiber stub dust cap simultaneously.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the joints of optical fibre dust cap synoptic diagram of prior art.

Among the figure: 1, dust cap body, 2, plush copper, 3, the hole, 4, web joint, 401, hole 402, connecting band, 403, the hole.

Embodiment

By shown in Figure 1, the upper end of former joints of optical fibre dust cap is an one flat plate.

By Fig. 2 and shown in Figure 3, a kind of improved joints of optical fibre dust cap of the present utility model, be at web joint 4 of the upper end of former dust cap adjunction, this web joint is covered in the dust cap upper end, and drag a connecting band 402 just as tail, this connecting band 402 passes the hole 3 that dust cap top avris is offered, and the termination of connecting band 4 is provided with connecting hole 403, can fix with the joints of optical fibre; In order to place the fiber stub dust cap, the fiber stub dust cap as shown in Figure 4, offer the hole 401 that to pass through the fiber stub dust cap at web joint 4 centers, and add a columniform plush copper 2, this plush copper 2 fiber stub dust cap that can be used to peg graft in dust cap body 1 central upper portion.

Claims

1. improved joints of optical fibre dust cap, one dust cap body 1 is arranged, it is characterized in that: be provided with a web joint (4) in the upper end of dust cap body (1), this web joint (4) is covered in the dust cap upper end, and drag a connecting band (402) just as tail, this connecting band (402) passes the hole (3) that dust cap top avris is offered, and the termination of connecting band (4) is provided with the joints of optical fibre and is fixedly coupled hole (403); Offer the hole (401) that to pass through the fiber stub dust cap at web joint (4) center; The columniform plush copper (2) of the fiber stub dust cap of can pegging graft is set in dust cap body (1) central upper portion.
