Description
Technical field
The utility model relates to a kind of connection device in the video signal transmission field, particularly a kind of Novel video wire and cable connector.
Background technology
For guaranteeing the video signal transmission effect, in the video signal transmission process, generally video cables need to be inserted in the accepting device reliably by connector, need simultaneously the connector signal reflection loss low.A kind of Novel video wire and cable connector is arranged in the prior art, comprise housing, attaching nut and be arranged at the contact pin of attaching nut inside, housing is that an end is provided with interface, and the other end is provided with the shell of connection jaws, and the contact pin front end is spherical in shape and stretch out along attaching nut's axis; The front insulating case of suit is arranged in the connection jaws behind the contact pin rear end welding cable, also is provided with top base and bottom base in the housing, and upper and lower pedestal is by snap ring and housing clamping, and contact pin is arranged in top base and the bottom base.
Its weak point is that the contact pin rear end is poor by being welded to connect cable cored wire conductor stretch-proof performance; Snap ring normal operation plastics are made, loss of properties on aging, and after a period of time, video cables and connector position are prone to loosening; Insulating case and upper and lower pedestal are insulating material, do not have the complete metal shielding between housing and the cable, and the signal reflex loss is larger.In addition, attaching nut and external equipment junction do not have seal, and the adapter connector place is waterproof well.
The utility model content
The problem that the utility model exists for prior art, the Novel video wire and cable connector that a kind of signal index is high, reflection loss is low, water resistance good, stretching resistance is strong is provided, be intended to reduce video cables connector place reflection loss, improve video signal transmission quality.
The purpose of this utility model is achieved in that a kind of Novel video wire and cable connector, comprises housing, attaching nut and is arranged at the contact pin of attaching nut inside, and described contact pin front end is spherical in shape and stretch out along attaching nut's axis; The contact pin rear end is stretched into enclosure interior and is set in the housing by rear insulating case, and inside, contact pin rear end also axially offers spliced eye; Contact pin middle part and the joint that is positioned at attaching nut and housing also are set with front insulating case, be provided with front bushing pipe between described attaching nut and the front insulating case, front bushing pipe is divided into large footpath section and path section by step transition, described large footpath section is arranged in the attaching nut, described path section stretch in the housing and with the anterior interference fit setting of housing; The inside of described housing also is provided with rear bushing pipe, the front portion of described rear bushing pipe is stretched between rear insulating case and the housing, and by being arranged at the limited step location of inner walls, the afterbody of described rear bushing pipe is provided with place's pawl groove at least, and described housing afterbody is provided with the thin-walled ring fillister corresponding with the pawl groove.
During the utility model work, the video cables termination is cut to internal layer successively annular by skin, making it be from inside to outside stairstepping distributes, then the cored wire conductor with video cables axially inserts in the rear bushing pipe together with insulating barrier, the bushing pipe tail end inserts first between insulating barrier and the cable sheath after this moment, make cable sheath enter annular gap between housing and the bushing pipe, cored wire conductor inserts in the spliced eye of contact pin rear end, after video cables is pegged graft and is put in place, axially oppress forward the housing afterbody, the pawl groove of rear bushing pipe afterbody and external shell synergy, so that the cannelure inwardly protruding interlocking cable sheath is in the rear bushing pipe afterbody pawl groove in the form of a ring, the video cables position is fixed.Compared with prior art, the beneficial effects of the utility model are: 1, by housing afterbody ring fillister and rear bushing pipe synergy interlocking cable sheath, when video cables is subjected to the axial tractive of external force, the ring fillister inwardly protruding is more obvious, so that video cables more firmly interlocking in the pawl groove, significantly improved the tensile property between video cables and the connector; 2, rear bushing pipe inserts between insulating barrier and the cable sheath, cable sheath and cable heart yearn are effectively isolated, failure line core when avoiding the cable location, also set up front bushing pipe between attaching nut and the front insulating case, when guaranteeing effectively insulation, also form metallic shield in the inner wire periphery, effectively reduce the signal reflex loss of connector, improved the signal transmission objective.The utility model can reliably be used for being connected and fixed of coaxial cable, is particularly useful for being connected and fixed of video cables.
Described backsight inside pipe wall is provided with the anticreep internal thread, during work, the cored wire conductor of video cables axially inserts in the rear bushing pipe together with insulating barrier, rotary shell, drive video cables insulating barrier on the anticreep internal thread rotation until the cable grafting puts in place, implement again axially to oppress forward the follow-up works such as housing afterbody.The anticreep internal thread the further tensile property of having strengthened between video cables and the connector is set, prevent that cable from getting loose, guarantee reliably to connect.
For preventing that rainwater, dust or wet gas etc. from entering cable inside by large footpath section and attaching nut's gap of front bushing pipe, to guarantee good signal transmission, described attaching nut's inwall and the section front portion, large footpath that is positioned at front bushing pipe offer the port sealing groove, are provided with the first sealing ring in the port sealing groove.
Be the further waterproof effect of strengthening, the large footpath section end face of bushing pipe and circumferential double sealing before realizing, the large footpath section periphery of described front bushing pipe is provided with step surface, is provided with the second sealing ring between step surface and the attaching nut's inwall.
The inwall of described spliced eye axially offers some profile grooves, and compressing profile groove clamping lines core conductor guarantees reliably to be electrically connected between the inner wire during rear insulating case stress deformation, and the signal transmission is more stable.
Described housing middle part outer surface is provided with some anti-slip tanks, and the housing middle part is connected by the transition of indent deep-slotted chip breaker with the front portion, make profile more attractive in appearance, be convenient to hand.
The terminal tapered contraction of described rear bushing pipe, convenient rear bushing pipe inserts between insulating barrier and the cable sheath accurate positioning, quick for installation.
