Technical field
The present invention relates to the inner bag signal transmission path design field of light station and amplifier in Hybrid Fiber Coaxial, is specifically a kind of transmission path structure of liner signal.
Background technology
In the Hybrid Fiber Coaxial (HFC) of prior art, adopt in the coaxial cable framework of plug-in RF module design, a kind of exchanging structure must be utilized, the radio-frequency (RF) signal (RF) on coaxial cable and coaxial cable power supply (CablePower) electric current are passed on inner bag pcb board by the joint male seat on housing pcb board (printed circuit board) and the joint female seat on inner bag pcb board.Its structure (as Fig. 1) comprises housing 1 ', housing pcb board 2 ', inner bag 6 ', inner bag pcb board 8 ', joint female seat 7 ', joint male seat 3 ' and PIN needle 4 ' (electronics contact pin).Described housing pcb board 2 ' is fixedly mounted on housing 1 ', described joint male seat and PIN needle are all fixedly connected on housing pcb board, described joint female seat is fixedly connected on inner bag pcb board, and joint female seat is fixedly mounted on inner bag by attaching nut 9 ', the lower end of described joint female seat is connected in joint male seat, the lower surface of joint female seat is provided with a jack 5 ' inserted for PIN needle free end, and the top of described PIN needle is plugged in jack.The radio-frequency (RF) signal of this transmission path structure of liner signal is passed on inner bag pcb board by the joint male seat on housing pcb board and PIN needle with coordinating of joint female seat, the inner bag that this inner bag adopts aluminium alloy to make, and its center tap male seat plays the effect of ground connection.The comparatively inconvenience of the transmission path structure of liner signal more complicated of this structure, assembling, production cost are high; In addition, radio-frequency (RF) signal is passed on inner bag pcb board by the joint male seat on housing pcb board and PIN needle with coordinating of joint female seat, distance between its housing pcb board and inner bag pcb board is comparatively large, thus makes the volume of transmission path structure of liner signal comparatively large, and space availability ratio is low.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defect of above prior art, provides that a kind of structure is simple, easy to assembly, cost is low and the transmission path structure of liner signal that space availability ratio is high.
Technical solution of the present invention is, there is provided a kind of transmission path structure of liner signal with following structure: it comprises housing, housing pcb board, inner bag, inner bag pcb board, joint female seat and PIN needle, described housing pcb board is fixedly mounted on housing, described inner bag is provided with a through hole inserted for joint female seat, the free end end face of described joint female seat is provided with a jack inserted for PIN needle, described inner bag pcb board is fixedly mounted on inner bag, the lower end of described joint female seat is fixedly connected on housing pcb board, the top of described PIN needle is connected with inner bag pcb board, the bottom of PIN needle is arranged in the jack on the free end end face of joint female seat, the described lateral wall of joint female seat is connected with the through-hole wall of inner bag.
After adopting above structure, transmission path structure of liner signal of the present invention compared with prior art, have the following advantages: in this transmission path structure of liner signal, inner bag pcb board is fixedly mounted on inner bag, the lower end of joint female seat is fixedly connected on housing pcb board, the top of PIN needle is connected with inner bag pcb board, the bottom of PIN needle is arranged in the jack on the free end end face of joint female seat, the lateral wall of joint female seat is connected with the through-hole wall of inner bag, owing to eliminating joint male seat, and the lateral wall of joint female seat is connected with inner bag through-hole wall, play the effect of joint female seat ground connection, therefore this transmission path structure of liner signal is simple, easy to assembly, production cost is low, and the Distance Shortened between housing pcb board and inner bag pcb board, thus reduce overall volume, improve space availability ratio.
As preferably, the through hole both ends of the surface of described inner bag are equipped with a cylindrical wall, described cylindrical wall and inner bag are formed in one structure, and the internal diameter of cylindrical wall equals the internal diameter of through hole, and described inner bag pcb board is fixedly connected with the cylindrical wall upper surface of inner bag by fixed screw; The described lateral wall of joint female seat is connected with the inwall of cylindrical wall.When inner bag pcb board is installed, only with fixed screw, inner bag pcb board need be fixed on cylindrical wall upper surface.Install very convenient, the cylindrical wall in these inner bag through hole both ends of the surface and through-hole wall instead of the joint male seat of prior art, and play ground connection effect.
