Abstract
An optical fiber connector comprises a butt terminal, a metal casing and a cable, wherein the metal casing is connected with the butt terminal, and the cable is provided with an optical fiber and is held in the metal casing and connected with the butt terminal. The butt terminal comprises a body and a pin extending forwards from the body. The metal casing is provided with a holding groove connected with the body. The pin is provided with a center hole which recesses backwards from the front surface of the pin and penetrates to the back surface of butt terminal, and the optical fiber is held in the center hole. The butt terminal further comprises a pair of butt joints which extend forwards from the body and disposed on two sides of the pin. The metal casing is provided with a pair of extension portions extending forwards from the front surface of the metal casing and located on two sides of the butt joints and the pin. Compared with the existing optical fiber connector, the optical fiber connector is more minimized and more convenient to mount.
Description
[technical field]
The relevant a kind of joints of optical fibre that are used for the computer data transmission of the present invention.
[background technology]
In infotech flourishing day by day today; Data transmission is very important, seeks the important topic that speed is faster, information transmitting medium that transinformation is bigger becomes current material science for satisfying application such as computer local network at a high speed, video conferencing, video request program.At present, in message transmitting procedure, operable is to be the copper cable of medium with the metal, is the silica fibre of medium with the quartz glass and is the plastic optical fiber of medium with the macromolecular material.Along with the transfer rate of optical fiber at computer network constantly develops, and the advantages of forming by plastic optical fiber such as that connector had was easy for installation, with low cost, antijamming capability is strong, more and more each computer networks that are applied to of such connector.
The joints of optical fibre are through long-term development, to the joints of optical fibre require increasingly high, the miniaturization of connector with make that to oversimplify be an important trend of development at present.The existing joints of optical fibre generally comprise with butt connector connect dock terminal, be installed on the metal shell of butt joint terminal rear end and be contained in metal shell and dock terminal in optical fiber cable; The butt joint terminal comprises columniform pin portion, be contained in butt connector host cavity housing and have the through hole that after docking terminal surface is through to pin portion front surface; Optical fiber cable is contained in through hole and its front end and pin portion front end face flush, and housing is enclosed by four walls and forms.Realize fool proof though housing and metal shell are joined through breach and boss mutually, because structure is limit, both are not easy breach to be alignd with boss when mounted, need repeatedly to attempt just working good at once.
Therefore, be necessary to provide a kind of joints of optical fibre to overcome the problems referred to above.
[summary of the invention]
Fundamental purpose of the present invention is the joints of optical fibre that miniaturization are provided and are convenient to install.
For realizing above-mentioned purpose; The present invention can adopt following technical scheme: a kind of joints of optical fibre; It comprises butt joint terminal, the metal shell that is connected with said butt joint terminal, has optical fiber and be contained in said metal shell and the said cable that docks terminal; Said butt joint terminal comprises body, from the pin portion that said body extends forward, said metal shell has the accepting groove that is connected with said body, said pin portion has the center pit on surface after its front surface caves in backward and is through to said butt joint terminal; Said optical fiber is contained in said center pit; Said butt joint terminal also comprises a pair of docking section of extending and be positioned at said pin portion both sides from said body forward, and said metal shell has a pair of extension that extends forward from its front surface, said extending part in said docking section, the both sides of said pin portion.
Compared with prior art, the beneficial effect of the joints of optical fibre of the present invention is: with respect to the existing joints of optical fibre, and the miniaturization more of these joints of optical fibre, more convenient installation.

Fig. 1 is the three-dimensional assembly diagram of the joints of optical fibre of the present invention.
Fig. 2 is the three-dimensional exploded view of the joints of optical fibre of the present invention.
Fig. 3 is the three-dimensional exploded view of another angle of the joints of optical fibre shown in Figure 2.
Fig. 4 is the cut-open view of A-A direction along the line shown in Figure 1.
[embodiment]
Please referring to figs. 1 through shown in Figure 4, the joints of optical fibre 100 of the present invention comprise butt joint terminal 1, the metal shell 2 that is connected with butt joint terminal 1, are contained in the cable 3 in the metal shell 2 and are contained in the inner module 4 in the metal shell 2.
Butt joint terminal 1 forms for the metal material casting, and the metal material of present embodiment is an aldary.Butt joint terminal 1 has the body 11 that is " protruding " font, cylindrical pin portion 13 reaches from the body 11 cylindrical connecting portion 14 that extends back from a pair of docking section 12 that body 11 extends forward, between docking section 12.Body 11 comprises second section 112 that is positioned at its anterior first section 111 and is positioned at first section 111 rear; Be smaller than first section 111 for second section 112; 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 that preceding is recessed to form 141, and pin portion 13 has the center pit 131 that runs 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 that extends along the butt joint direction.
During assembling; The optical fiber 31 of cable 3 is installed forward from docking terminal 1 rear end, and it passes groove 141 and exposes to pin portion 12 front end faces with 131, one sections optical fiber 31 of center pit; Exposed optical fiber 31 is accommodated and center pit 131, insulation endothelium 32 be contained in groove 141 and with groove 141 mutual extrusion.The connecting portion 14 of butt joint terminal 1 and through hole 41 interference fit of inner module 4, the surface, body 11 back of butt joint terminal 1 offsets the through hole 41 and external insulation skin 33 mutual extrusion of inner module 4 with the front surface of inner module 4.
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 butt joint terminal 1; Can do reference with the docking section 12 and the relative position of extension 22; Make main part 11 aim at accepting groove 21, connect in the disposable accepting groove 21 that makes main part 11 insert metal shell 2.
