[embodiment]
Please refer to shown in Fig. 1 to Fig. 4, the joints of optical fibre 100 of the present invention comprise docking terminal 1, the metal shell 2 being connected with docking terminal 1, are contained in the cable 3 in metal shell 2 and are contained in the inner module 4 in metal shell 2.
Docking terminal 1 is cast and is formed for metal material, and the metal material of the present embodiment is aldary.Docking terminal 1 have be the body 11 of " protruding " font, a pair of docking section 12 of extending forward from body 11, cylindrical pin portion 13 and from the body 11 cylindrical connecting portion 14 that extends back between docking section 12.Body 11 comprises the second segment 112 that is positioned at its anterior first paragraph 111 and is positioned at first paragraph 111 rears, second segment 112 is smaller than first paragraph 111, pin portion 13 front end faces surpass the front end face of docking section 12, connecting portion 14 has from its rear end towards the groove 141 being front recessed to form, pin portion 13 has the center pit 131 running through backward from its front end face, and center pit 131 connects with groove 141.The outside surface of docking section 12 has the projection 121 extending along abutting direction.
Metal shell 2 is for zinc alloy diecasting forms, and it comprises a pair of extension 22, the accepting groove 21 that autonomous body 20 front surfaces are recessed to form backward, the cylindrical protective portion 23 that autonomous body 20 rear surfaces extend back and the accepting hole 231 that connects protection portion 23 rear surfaces and communicate with accepting groove 21 that the main part 20 that is roughly rectangular parallelepiped, autonomous body 20 front surfaces extend forward.Extension 22 ends have the fin perpendicular with abutting direction 221.
Cable 3 comprises and is positioned at the optical fiber 31 at center, the external insulation skin 33 of the insulated hull 32 of clad optical fiber 31, coated insulated hull 32, and optical fiber 31 leading portions expose to interior insulated hull 32 and external insulation skin 33.
Inner module 4 is for plastic rubber ejaculate molding forms, and it has the through hole 41 that runs through front and rear surfaces.
During assembling, the optical fiber 31 of cable 3 is installed forward from docking terminal 1 rear end, and it exposes to pin portion 12 front end faces through groove 141 and 131, one sections of optical fiber 31 of center pit, exposed optical fiber 31 is accommodated and center pit 131, and interior insulated hull 32 is contained in groove 141 and mutually pushes with groove 141.The connecting portion 14 of docking terminal 1 offsets with through hole 41 interference fit of inner module 4, body 11 rear surfaces of docking terminal 1 and the front surface of inner module 4, and through hole 41 and the external insulation skin 33 of inner module 4 push mutually.
Metal shell 2 is connected with docking terminal 1, the accepting groove 21 of metal shell 2 is accommodated the connecting portion 14 of docking terminal 1 and the second segment 112 of body 11, the front surface of metal shell 2 supports the rear surface of the first paragraph 111 of body 11, accepting groove 21 and second segment 112 interference fit of metal shell 2, two surfaces of metal shell 2 are mutually concordant with the outside surface of first paragraph 111, extension 22 is positioned at the both sides of pin portion 13, and docking section 12 lays respectively at four faces of tubular rectangular parallelepiped and is spaced from each other with extension 22.Extension 22 surrounds pin portion 13 with docking section 12, and extension 22 does not exceed the front end face of docking section 12, and the front end face of pin portion 13 exceeds described extension 22 front end faces.The rear surface of the interior rear surface of metal shell 2 and inner module 4 offsets.Cut away the optical fiber 31 that exposes to pin portion 13 front ends, the front surface that makes optical fiber 31 aligns with pin portion 13 front surfaces.
Because the extension 22 of metal shell 2 is positioned at pin portion 13,12 both sides, docking section, when metal shell 2 is connected with docking terminal 1, can do reference with docking section 12 and the relative position of extension 22, make main part 11 aim at accepting groove 21, in the disposable accepting groove 21 that makes main part 11 insert metal shell 2, connect.
