Abstract

An optical fiber connector comprises a first connector; a second connector; a sleeve which is coaxially arranged in the first connector and the second connector; a shell, wherein a holding chamber is defined in the shell and can hold the first connector and the second connector, a fastener is inwardly formed on the inner wall of the holding chamber so that the first connector can be limited and positioned by the fastener, and the shell is provided with at least one slot leading to the holding chamber; and at least one U-shaped clamp which is inserted into the slot of the shell to limit the second connector held in the shell so that the first connector and the second connector can be forced to be firmly arranged in the shell. Because the shell of the connector is integrally formed, the ultrasonic fusion process is not needed, the external damage-resisting strength of the optical fiber connector can be greatly enhanced, and moreover, since the connector utilizes the U-shaped clamp to firmly combine the first and the second connectors and the shell together, the reliability of the optical connector is further improved.

Description

The joints of optical fibre

Technical field

The relevant a kind of joints of optical fibre of the present invention refer to that especially a kind of shell body is formed in one, and do not need ultrasound wave to fuse the joints of optical fibre of operation.

Background technology

The joints of optical fibre are widely used in the connection work of fibre-optical splice; Its major function is two optical fiber cables that continue; Make light signal through carrying out the transmission of signal between the optical fiber cable of connector by the optical fiber cable of an end and the other end; Make the telecommunications dealer can see through connected mode according to this signal is passed to client, so these joints of optical fibre are played the part of important role in fiber-to-the-home, optical communication transmission.

Shown in Figure 1A, Figure 1B, known fiber optic connector 10 comprises that one first shell body, 11, one second shell bodies 12 make it engage with first shell body 11 with the ultrasound wave mode of fusing; One first conjunction 13 is placed in first shell body 11, and this first conjunction 13 has one first inner sleeve 14 and a pair of geometrical clamp 15; One second conjunction 16 is placed in second shell body 12, and this second conjunction 16 has one second inner sleeve 17 and a pair of geometrical clamp 18; And a sleeve 19 coaxial being arranged in this first inner sleeve 14 and second inner sleeve 17, and the headgear (Ferrule) 21 of fibre-optical splice 20 is inserted in this sleeve 19, and make this fibre-optical splice 20 be linked to this joints of optical fibre 10.

These joints of optical fibre 10 have several intrinsic problems in assembling: the first, and fuse and stay in the joint of first shell body 11 and second shell body 12 and to fuse vestige with ultrasound wave, visually more not attractive in appearance.The second, because the engaging force that utilizes ultrasound wave to fuse is firm inadequately, the joints of optical fibre 10 receive when clashing into, and are prone to make first shell body 11 to separate with second shell body 12.

Need a kind of integrated shell body at present, it can protect the mechanical connection between part forever, and does not need the other operation that fuses.

Summary of the invention

Fundamental purpose of the present invention provides a kind of joints of optical fibre, and its shell body is formed in one, and can improve bulk strength, and does not need other ultrasound wave to fuse operation.

Secondary objective of the present invention provides a kind of joints of optical fibre, and it utilizes at least one U-shaped anchor clamps to make a pair of conjunction and shell body form firm combining.

For reaching above-mentioned purpose and effect, the joints of optical fibre of the present invention comprise:

One first conjunction has an end plate, and one first inner sleeve is arranged on this end plate, and a pair of geometrical clamp is arranged on the both sides of this first inner sleeve;

One second conjunction has an end plate, and one second inner sleeve is arranged on the end plate of this second conjunction, and a pair of geometrical clamp is arranged on the both sides of this second inner sleeve;

One sleeve, coaxial setting should be in first, second inner sleeve;

One shell body, its inside has the room of first, second conjunction of receivability, and the internal face of this room inwardly is formed with a clamping piece, makes the end plate of this first conjunction receive the engaging of clamping piece and locatees; One first connectivity port can supply a fibre-optical splice to connect; One second connectivity port can supply another fibre-optical splice to connect; And at least one groove leads to this room from the outer wall of this shell body; And

At least one U-shaped anchor clamps, the groove of this shell body inserts certainly, and the end plate of this second conjunction is limited, and forces first conjunction and second conjunction firmly to be arranged on the inside of this shell body.

These U-shaped anchor clamps comprise a sheet body and a two side arms, and it is terminal that this two side arms is located at this sheet noumenon respectively.

Compared with prior art; The beneficial effect that the present invention had is: the shell body of the joints of optical fibre of the present invention structure that is formed in one; Can significantly improve the intensity of opposing outside destroy; And the vestige that does not fuse in appearance, and the present invention utilizes at least one U-shaped anchor clamps to make first, second conjunction form firm combining with this shell body, further improved the reliability of these joints of optical fibre.

According to above-mentioned purpose, lift preferred embodiment now and cooperate technological means that the graphic the present invention of explanation adopts and effect.
