Abstract

Provided is an optical fiber connector, comprising a plug member, a socket member clamped with the plug member, and a fastener arranged in the plug member and the socket member. The plug member comprises a housing seat, two buckle holes formed on the housing seat at opposite positions, and a guide groove formed on the housing seat and extended along the length direction of the housing seat. The socket member comprises a base, a penetrating portion extended from the base to penetrate into the plug member, two buckle blocks which are protrudingly extended from the penetrating portion and are corresponding to the buckle holes of the plug member, and a guide block which is protruded from the penetrating portion and is tightly matched with the guide groove of the plug member correspondingly. AsAsAsAs AAs the guide groove of the plug member is deformed only at two sides of the guide block of the socket member during the combination of the guide groove and the guide block, the deformation is reduced, thereby increasing the strength in clamping the guide block.

Description

The joints of optical fibre

Technical field

The utility model relates to a kind of fibre-optical splice, particularly relates to a kind of joints of optical fibre.

Background technology

Consult Fig. 1; For TaiWan, China is announced " joints of optical fibre " M387259 number; Be used for being connected with an optical fiber, these joints of optical fibre comprise a procapsid 11, one with this procapsid 11 back casing 12 of clamping mutually, and the core pipe 13 be located in this procapsid 11 and the back casing 12.

This procapsid 11 comprises that a shell block 111, two is formed on the engaging projection 114 that the blocking hole 112 of 111 liang of opposite location of this shell block, is protruded out by these pressure bullet portion 113 both sides by the pressure bullet portion of these shell block 111 oblique extensions 113, two; And the assembling guide groove 115 that is formed on this shell block 111, because 112 in this blocking hole that concerns at visual angle shows one.

This back casing 12 comprise a pedestal 121, one by this pedestal 121 extend and be used to stretch into this procapsid 11 assembled portion 122, two by this assembled portion 122 protrude out and respectively with the blocking hole 112 corresponding blocking projections 123 of this procapsid 11; And one by this assembled portion 122 protrusions and the assembling raised line 124 that matches with the assembling guide groove 115 of this procapsid 11, because 123 of this blocking projections that concern at visual angle show one.

These core pipe 13 two ends are located at respectively in this procapsid 11 and the back casing 12, and comprise first contact pin 132 that a pedestal 131, is extended by these pedestal 131 1 ends, and second contact pin 133 that extended by these pedestal 131 other ends.

Be this core pipe 13 to be stretched insert this procapsid 11 and make this first contact pin 132 partly protrude out this procapsid 11 in the use; Afterwards; Stretch into this core pipe 13 with a fiber-optic signal line (figure does not show) by this second contact pin 133; At last this back casing 12 is fixed with this procapsid 11 again; This back casing 12 is to be fixed togather with the blocking projection 123 blocking hole 112 with this procapsid 11, utilizes the assembling guide groove 115 of this procapsid 11 to cooperate to guarantee assembling rightness with the assembling raised line 124 of back casing 12 simultaneously, make this procapsid 11 and back casing 12 can turned upside down, instead adorn; The pressure bullet portion 113 that just can push this procapsid 11 thus reaches the function of transmission signals to insert a bogey (figure does not show).

Because the assembling raised line 124 of above-mentioned back casing 12 is directly to be extended by this pedestal 121 walls protrusion and join with this pedestal 121; Therefore behind the assembling guide groove 115 that inserts this procapsid 11; Assembling guide groove 115 can make that the deflection of this assembling guide groove 115 is more and more big towards openend because receive the cause that assembling raised line 124 struts, and causes folder to establish the dynamics deficiency of this assembling raised line 124; Take place easily to become flexible, have influence on the degree of stability that procapsid 11 combines with back casing 12.
