Abstract

The utility model relates to a mechanical continuous type socket for fiber-optic connectors which can be repeatedly plugged and pulled. The socket for fiber-optic connectors is composed of three components: a socket body, a casing tube and a spring expansion ring, wherein, the socket body comprises a head sleeve for placing the casing tube, the ring groove of the spring expansion ring which is tabled with the socket body, thread outer tubes which is positioned at the two ends of the socket body and is screwed with the plug of a fiber-optic connector, etc. The socket body is made into in an integral forming processing method to ensure the concentric precision of the fiber-optic socket and plug after being tabled; consequently the loss of the splicing points of the optical transmission is decreased, and the change of the loss value caused by being repeatedly used is made to be minimum. The socket for fiber-optic connectors has convenient assembly, only the casing tube is loaded in the head sleeve, and the spring expansion ring is inserted to fix.

Description

Socket for fiber-optic connector

Socket of the present utility model is to be used for the usefulness that optical fiber connector plug inserts connection, can repeat to plug the fiber connector socket of use for a kind of mechanical type continuous type.

The fiber connector socket of commonly using, the body that its two ends and Optical fiber plug outer tube sleeve are share divides two to make, the headgear of loading sleeve pipe is also made two, during assembling, two headgears are inserted in from the sleeve pipe two ends respectively it are gripped, again this assembly is packed between two jack bodies, fix with screw in jack body gabarit diagonal position.Because it is many to form the assembly of socket, not only assembling is taken a lot of work, and no matter make or assemble, all may be because of cumulative errors, be difficult for keeping accurate concentric fit each other, because Optical Fiber Transmission, very strict to two optical fiber its mutual concentricity requirement when engaging, a little deviation can cause the conduction loss between splicing point.

The purpose of this utility model is to overcome the disappearance of the fiber connector socket of commonly using, and designs a kind of integrated body, the concentricity precision when connecting to improve optical fiber.

It is by a jack body for the utility model, one sleeve pipe and a spring piston ring are formed, jack body comprises the screw thread outer tube that the annular groove of the headgear of loading sleeve pipe, the spring piston ring chimeric with it and two ends and optical fiber connector plug thereof screw togather, jack body system forms with one-body molded job operation manufacturing, simplified assembly quantity, improve concentricity precision, reduce the loss of light transmission splicing point, it is minimum that the loss value of heavily covering use is changed, its degree of stability is under environmental test, and small variable is lost in the 0.1db.

Structure content of the present utility model, characteristics and effect can further be understood from the detailed description of conjunction with figs..

Brief Description Of Drawings:

Fig. 1 is the stereographic map of the utility model fiber connector socket embodiment.

Figure 1A is the annular groove part enlarged drawing that the piston ring spring is used among Fig. 1.

Fig. 2 is the planimetric map of this practical fiber connector socket embodiment.

Fig. 2 A is the longitudinal component cut-open view of the utility model fiber connector socket embodiment.

Fig. 3 is the optical fiber connector plug stereographic map that the utility model socket is used.

Consult Fig. 1 and 2, the stereographic map of the utility model fiber connector socket embodiment, wherein include: a jack body 11 with one-body molded job operation manufacturing, three assemblies such as one sleeve pipe 12 and a spring piston ring 13, during assembling, sleeve pipe 12 is packed in the sleeve pipe headgear 15 in the socket, embed to be fixed in the annular groove 17 of headgears one end with turn 13 again and getting final product.

More detailed explanation, described jack body 11 central authorities are provided with a headgear 15 that is oval tubular, and an end of this headgear 15 is provided with the flange 16 of invagination, and the other end is provided with a circle annular groove 17, the periphery of this headgear is provided with a screw thread outer tube 14, and the periphery of this screw thread outer tube 14 is provided with a flange 18.The diagonal position of this flange is provided with bolt penetration hole 19.Described sleeve pipe is cylindric, and the tube wall of this sleeve pipe is provided with axially open 10 one.Described piston ring spring 13 utilizes the telescopic resilience of 13 tools of this spring piston ring can be embedded in the annular groove 17 and sleeve pipe 12 can be fixed in the headgear 15 in the form of a ring.Headgear 15 set on the described jack body 11 is a concentric with screw thread outer tube 14.

The utility model system cooperates the optical fiber connector plug 2 of Fig. 3 to use together, when connecting, the optic fibre headgear 21 of plug, insert in the sleeve pipe 12 in the socket 1, the sleeve pipe headgear 15 of socket then enters in the fixedly headgear 22 of plug, have externally threaded outer tube 14 on the outer tube sleeve 23 that will have internal thread again and the socket and be tightened, because body series of the present utility model is one-body molded, so mutual center accurately cooperates can guarantee the optical fiber connection time.
