Abstract
A dustproof cap for an optical fiber connector is provided. The dustproof cap comprises a dustproof cap body, the outer surface of the front end of the dustproof cap body is provided with a plurality of reinforcing ribs fitted and fixed with a frame sleeve of the optical fiber connector, and root parts of the reinforcing ribs are connected with a guard ring of the front end of the sealed frame sleeve. By adopting the dustproof cap, secondary pollution is avoided, the dustproof protection effect is good, the structure is simple and practical, and the operation is convenient.
Description
Technical field
The utility model belongs to optical communication field, relates to a kind of dust cap that is used for the joints of optical fibre.
Background technology
The existing dust cap that is used for the joints of optical fibre is shown in Fig. 1-4; Comprise connector pin 2 '; Dust cap 1 ' or 1 " can directly be enclosed within contact pin 2 ' on; the mode through interference fit with dust cap 1 ' or 1 " be fixed on contact pin 2 ' on, thereby reach the pollution that protection contact pin 2 ' end face does not receive external environment.Because mostly existing dust cap is injection mo(u)lding, it more or less can be with a little dusts in the process of using, and in the interference fit process, also can bring some extra dusts simultaneously.Connector will bring the pollution of end face in use like this, even can bring extra insertion loss, can cause contact pin 2 ' end face damage when serious.
Summary of the invention
The interference fit that the utility model will solve existing dust cap and contact pin can make the end face of contact pin receive pollution problems, and a kind of dust cap that is used for the joints of optical fibre that can not let the contact pin end face polluted is provided.
The technical scheme that the utility model adopts is:
A kind of dust cap that is used for the joints of optical fibre; Comprise the dust cap body; It is characterized in that: the outside surface of the front end of said dust cap body is provided with many reinforcement ribs with the frame of joints of optical fibre cover matching and fixing, and the root of said reinforcement rib is connected with the guard collar that the sealing frame overlaps front end.
Further, the rear end of said dust cap body is an extension rod, and the tail end of said extension rod is a square structure.
Perhaps, the rear end of said dust cap body is the back seat that enlarges.
Further, said reinforcement rib is to be symmetrically distributed on the outside surface of dust cap body.
The technical conceive of the utility model; Tighten up through the external diameter of dust cap body and the loose mail of connector; To tighten up and the dustproof purpose in order reaching, on the dust cap body, to have designed the reinforcement rib of four symmetrical distributions especially, and guard collar; Thereby the dust cap body is fixed on the connector loose mail closely, reaches the purpose of dustproof protection.And the dust cap body do not contact with the end face of contact pin, between have the gap, avoided the secondary pollution that brings because of cooperation.The setting of dust cap body rear end is conveniently connector to be operated.
The beneficial effect of the utility model: avoided secondary pollution, made that dustproof protection effect is good; And it is simple and practical, easy to operate.

Embodiment
Come the utility model is further specified below in conjunction with specific embodiment, but the utility model is not confined to these embodiments.One skilled in the art would recognize that the utility model contained in claims scope all alternativess, improvement project and the equivalents that possibly comprise.
Embodiment one
Referring to Fig. 5, Fig. 6; A kind of dust cap that is used for the joints of optical fibre; Comprise dust cap body 1, the outside surface of the front end of said dust cap body 1 is provided with the reinforcement rib 2 that many frames with the joints of optical fibre overlap 7 matching and fixing, and the root of said reinforcement rib 2 is connected with the guard collar 3 that the sealing frame overlaps 7 front ends.
The rear end of said dust cap body 1 is an extension rod 4, and the tail end of said extension rod 4 is square structures.
Said reinforcement rib 2 is to be symmetrically distributed on the outside surface of dust cap body 1.
Be that symmetry is evenly equipped with 4 reinforcement ribs on the outside surface of the dust cap body 1 in the present embodiment.
The technical conceive of the utility model; Tighten up through the external diameter of dust cap body 1 and the loose mail of connector; To tighten up and the dustproof purpose in order reaching, on dust cap body 1, to have designed the reinforcement rib 2 of four symmetrical distributions especially, and guard collar 3; Thereby dust cap body 1 is fixed on the connector loose mail closely, reaches the purpose of dustproof protection.And dust cap body 1 do not contact with the end face of contact pin 6, between have the gap, avoided the secondary pollution that brings because of cooperation.The setting of dust cap body 1 rear end is conveniently connector to be operated.
The tail end of the extension rod 4 in the present embodiment comes the handled easily except using square mode, still directly adopts end face to handle the mode of increase friction force, such as frosted etc.; Simultaneously also can come handled easily through the mode of chamfered edge.
Embodiment two
Referring to Fig. 7, Fig. 8, the difference of present embodiment and embodiment one is that the rear end of said dust cap body 1 is the back seat 5 that enlarges.All the other 26S Proteasome Structure and Functions are all identical with embodiment one.
Claims (4)
