Abstract

The invention relates to a pin assembly for an optical fiber adapter. The pin assembly comprises a sheath, two ceramic pins respectively assembled on two ends of the sheath, and a sheathed optical cable connected with the two ceramic pins, wherein, the optical cable is positioned in the sheath; inserting ends of the two ceramic pins respectively extend outside the corresponding ends of the sheath; and as the pin assembly for the optical fiber adapter comprises the two ceramic pins and the sheathed optical cable which is connected between wire inlet ends of the two ceramic pins, the two ceramic pins are connected through the optical cable and then are fixedly assembled in the sheath. The pin assembly for the optical fiber adapter has the beneficial effects that by adopting the common sheathed optical cable, the two ceramic pins can be connected with the optical cable by a conventional technology and the length of the optical cable and the sheath can be adjusted to adapt to the length of the pin assembly when in use so that the conventional standard pins can be utilized as the ceramic pins, which greatly lowers the machining difficulty of the pin assembly and solves the problems of the existing optical fiber adapter such as long machining period and low production efficiency resulting from overlong pins.

Description

A kind of fiber optic adapter contact pin assembly

Technical field

The present invention relates to joints of optical fibre field, especially a kind of fiber optic adapter contact pin assembly.

Background technology

Therefore the optical fiber adaptor connector in use needs two ends to plug together with adaptive connector simultaneously owing to will transfer to light path, requires adaptor connector through walls in some occasions; Be that its two ends lay respectively at inside and outside the body of wall, this just requires the length of its inner switching contact element longer, and in the prior art; The switching contact element of most of optical fiber adaptor connectors is single ceramic contact pin; Because this ceramic contact pin is slim-lined construction, therefore processing and assembly technology are extremely complicated, and product percent of pass is low; Thereby increased the production cycle of product, can't satisfy the production needs.

Summary of the invention

The object of the present invention is to provide a kind of fiber optic adapter contact pin assembly, solved the problem that process-cycle is long, production efficiency is low that existing fiber optic adapter causes owing to contact pin is long.

In order to address the above problem; Fiber optic adapter contact pin assembly of the present invention adopts following technical scheme: a kind of fiber optic adapter contact pin assembly; Comprise sheath; Be assemblied in two ceramic contact pins at sheath two ends places respectively and connect the optical cable of the belt leather of two ceramic contact pins, said optical cable is positioned at sheath, and the inserted terminal of two ceramic contact pins all stretches out the corresponding end of sheath.

Said sheath comprises first, second half cover that radially fastens mutually along said ceramic contact pin.

In said first, second half cover one is provided with bayonet socket and/or card key in the two relative side, and another is provided with corresponding card key and/or bayonet socket, and first, second half cover is through said card key and bayonet socket snap fit.

The outside wall surface of said first, second half cover is provided with corresponding groove, and first, second groove that partly puts is spliced into annular groove after first, second fastens, and hoop is provided with O-ring seal in the said annular groove.

In said first, second half cover at least one is provided with glue filling opening.

The end of incoming cables of said two ceramic contact pins be oppositely arranged and two ceramic contact pins all with the coaxial setting of said sheath.

The coaxial spring that is sheathed on the optical cable periphery that is equipped with in the said sheath, the place, two ends in said spring on the internal face of sheath is provided with interior convex edge respectively, and spring is mounted between the said two interior convex edges.

Because said fiber optic adapter contact pin assembly comprises two ceramic contact pins and is connected in the optical cable of the belt leather between the end of incoming cables of two ceramic contact pins that said two ceramic contact pins connect the back through said optical cable and fixedly are assemblied in the sheath; Because said optical cable is the ordinary optical cable of belt leather; Therefore can said two ceramic contact pins be connected with described optical cable through conventional technology in use; The length that adapts to the contact pin assembly through the length of regulating said optical cable and sheath; Thereby make said ceramic contact pin can adopt the contact pin of standard, routine, greatly reduce difficulty of processing, solved the problem that process-cycle is long, production efficiency is low that existing fiber optic adapter causes owing to contact pin is long the contact pin assembly.

Embodiment

The embodiment 1 of fiber optic adapter contact pin assembly shown in Fig. 1-7, has two ceramic contact pins 1, and ceramic contact pin 1 adopts the LC contact pin, is provided with the optical cable 2 of belt leather between 1 coaxial setting of two ceramic contact pins and the end of incoming cables of the two and passes through optical cable 2 to connect; Two ceramic contact pins 1 connect the corresponding end that the back fixedly is assemblied in the sheath 3 and the inserted terminal of the two all stretches out sheath through optical cable 2; Sheath 3 adopts nonmetal covers and is made up of the first half cover 3-1, the second half cover 3-2; First, second half cover radially fastening mutually along ceramic contact pin 1; Specifically; Promptly the first half cover 3-1 are provided with bayonet socket 3-1.1 and card key 3-1.2 towards the side of the second half cover 3-2; The second half cover face 3-2 are provided with the card key bayonet socket and card key corresponding with bayonet socket that puts with the first half to a side of the first half covers, and first, second partly overlaps the relative side back of fitting and connects and fixes through said card key and bayonet socket, and the structure of sheath 3 employing two halves buckle-types can realize the quick of two ceramic contact pins 1 fixed easily; The outside wall surface of first, second half cover is provided with corresponding groove and first, second groove that partly puts is spliced into annular groove after first, second fastens; Hoop is provided with O-ring seal 4 in the said annular groove, and the sealing when O-ring seal 4 can be realized this contact pin assembly and corresponding connector shell on the one hand can prevent that together the two from getting loose with first, second half cuff after fastening on the other hand; First, second partly puts and is equipped with glue filling opening 3-3; Glue filling opening 3-3 is used to supply glue to pass through to fill the inner chamber of sheath 3; Can realize the further fixing of first, second half cover on the one hand; Then realized the sealing to two ceramic contact pins 1 and optical cable 2 on the other hand, simultaneously, glue has also strengthened the cooperate intensity of optical cable 2 with ceramic contact pin 1 after solidifying; The coaxial spring 5 that is sheathed on optical cable 2 peripheries that is equipped with in the sheath 3; On the internal face of sheath 3 in place, the two ends of spring 5 is provided with respectively convex edge 3-4; Spring 5 is mounted between the two interior convex edges; Spring 5 is used to guarantee that ceramic contact pin 1 can grind through the existing special-purpose frock of grinding, and then improves the performance of ceramic contact pin aspect face type and loss.
