Embodiment
As shown in Figure 1-2, a kind of electromagnetic shielding type joints of optical fibre that plug described in the utility model embodiment, comprise interconnective plug and socket, described plug comprises plug body 1 and is installed on the plug core main body 2 in plug body 1, described socket comprises jack housing 3 and is installed on the socket core main body 4 in jack housing 3, the two ends of plug core main body 2 and socket core main body 4 are provided with respectively joint 5 and protect cable spring 6, one end of described plug body 1 and jack housing 3 is all provided with outer regulating sleeve 7, outer regulating sleeve 7 one end are provided with the fastening shell 8 of tail end, described plug body 1 is interior is equipped with fixedly inner sleeve 9 of cable near the fastening shell 8 of tail end and the outer 3 interior close fastening shell of tail end 8 places of socket, cable is fixedly provided with sealing gasket 10 in inner sleeve 9 one end, the junction of described plug body 1 and jack housing 3 is equipped with anti-skidding pin-and-hole 11, plug body 1 and jack housing 3 are equipped with docking guide groove 12 near anti-skidding pin-and-hole 11 places, described joint 5 one end connect stroke spring 14, joint 5 is provided with latch 13, plug and socket interconnects by described anti-skidding pin-and-hole 11 and latch 14, described latch 14 could insert when inserting butt hole mutually, other any positions all can not be inserted, blindmate and Anti-misplug function have been realized.
Described plug body, jack housing, the fastening shell of tail end, outer regulating sleeve, outer waterproof grommet, light coupling assembling, plug core main body, socket core main body sealing gasket all adopt aluminium alloy, and easily process on surface, sturdy and durable, attractive in appearance; Full metal jacket, can effectively realize electromagnetic screen, removes external disturbance, has strengthened connection reliability.
Described plug and socket is all designed with shockproof de-structure, in the time of docking, in the time of along 60 ° of docking guide groove rotary connector and sockets, the connecting pin of socket and plug can slip into semi-circular connection pin-and-hole, under the effect of socket and plug inside parts stroke spring, firmly locking, has realized under the operating mode of vibration, and plug is closely connected with socket.
The described afterbody that protects cable spring has guaranteed that optical cable is when certain angle bends, and cable does not contact backfin wearing and tearing and rubs with the fastening shell 2 of metal parts tail end, more safe and reliable.
In described Socket casing, be also provided with outer waterproof grommet 15, sealing circle is silica gel sealing ring, effectively dustproof and waterproof after light coupling assembling connects, the flanged dish of outer waterproof grommet, screw via hole and silica gel sealing ring, can pass car wall or other fixed sturctures, realizes and being connected with outside waterproof; Jack housing can regulate the elasticity of connection, guarantees to connect; Plastic cement sealing gasket wringing fit shell and cable, fully guarantee that cable water can not enter enclosure interior, to reach water-proof function.
During concrete use, open the dust cap of plug and socket, latch is aimed to the other side's anti-skidding pin-and-hole, pulled down plug body and jack housing, get out of the way the latch of socket and plug, rotary connector and socket 60 degree, aim at anti-skidding pin-and-hole, naturally unclamps, under the effect of stroke spring, latch is firmly locked in anti-skidding pin-and-hole, then locks the outer regulating sleeve of plug and socket, and connection completes; When separated, only need up pull respectively plug body and jack housing, make latch depart from anti-skidding pin-and-hole, toward opposite spin 60 degree, plug and socket are separable.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
