Description
Technical field
The utility model relates to a kind of Power tabs, is mainly used in mobile communication antenna feeder part.
Background technology
Development along with the 4th third-generation mobile communication, present mobile communication base station all tends to miniaturization, outdoorization, and replace original antenna feeder part with optical cable and power line gradually, and directly directly pass to the radio frequency remote unit RRU part of base station with photoelectric mixed cable, price is very high.If can utilize original antenna feeder, only add an optical cable and pass to the RRU part, then cost is very low.And the cable in order to connect original antenna feeder and newly to add then need design a kind of new Power tabs.
Summary of the invention
For addressing the above problem, the utility model provides a kind of Power tabs, and this Power tabs can be docked with original female on the antenna feeder, and can access an optical cable, so that the cost of mobile communication antenna feeder part.
For achieving the above object, the concrete technical scheme that the utility model adopts is:
A kind of Power tabs, comprise swivel nut, one end is threaded onto the shell in the swivel nut, be fixed in the insulator in the shell, be embedded in the contact pin in the insulator, sealing ring and embedding spring are arranged between shell and swivel nut, in the other end of described shell, be fixed with successively large sealing packing ring, inner core, the large cable clip that is connected with outer casing screw, described large sealing packing ring, inner core, large cable clip is coaxial with contact pin, described inner core has an edge that extends vertically, described edge is embedded in the large cable clip, there is a blind hole side at described shell and large cable clip homonymy, the axial centre line parallel of the axis of described blind hole and contact pin, described blind hole near its bottom one section above the part that screws that passes shell is arranged, the described part that screws communicates with blind hole is vertical, is fixed with successively small sealing ring in another section of described blind hole, the little cable clip that is connected with outer casing screw.
The head of described large cable clip has the flange of the side that can be stuck in shell, and the head of described little cable clip has the flange of the side that is stuck in shell.
Described screwing packing ring one is arranged between part and the shell.
Further, described screwing between part and the packing ring one packing ring two is arranged.
Described packing ring one is all plain washer with packing ring two.
The described part that screws is soket head cap screw.
The utility model is simple in structure, and this Power tabs can be docked with original female on the antenna feeder, and can access an optical cable, so that the cost of mobile communication antenna feeder part.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the A-A cutaway view among Fig. 1;
Fig. 3 is the B-B cutaway view among Fig. 1.
Wherein: swivel nut 1, sealing ring 2, embedding spring 3, insulator 4, contact pin 5, shell 6, packing ring 1, packing ring 28 screws part 9, small sealing ring 10, little cable clip 11, flange 11-1, large sealing packing ring 12, inner core 13, edge 13-1, large cable clip 14, flange 14-1, blind hole 15.
Embodiment
The below is further described the utility model to closing drawings and Examples.
In Fig. 1～Fig. 3, a kind of Power tabs, comprise that swivel nut 1, an end are threaded onto shell 6 in the swivel nut 1, are fixed in insulator 4 in the shell 6, are embedded in the contact pin 5 in the insulator 4, have sealing ring 2 and embedding spring 3, the flat Ο type circle of the present embodiment sealing ring 2 employings between shell 6 and swivel nut 1; The large cable clip 14 that in the other end of shell 6, be fixed with successively the large sealing packing ring 12 coaxial with contact pin 5, inner core 13, is threaded with shell 6; Inner core 13 has an edge 13-1 who extends vertically, and edge 13-1 is embedded in the large cable clip 14.
The blind hole 15 that the axial centre line parallel of one axis and contact pin 5 is arranged in shell 6 and the side of large cable clip 14 homonymies, blind hole 15 near one section of its bottom above have pass shell 6 screw part 9, screw part 9 and blind hole 15 vertical communicating, packing ring 1, packing ring 28 are arranged screwing between part 9 and the shell 6, the present embodiment screws part 9 and is soket head cap screw, packing ring 1 is all plain washer with packing ring 28, the little cable clip 11 that is fixed with successively small sealing ring 10, is threaded with shell 6 at another section of blind hole 15.
The head of large cable clip 14 has the flange 14-1 of the side that can be stuck in shell 6, and the head of little cable clip 11 has the flange 11-1 of the side that is stuck in shell 6.
The present embodiment is as example take 7/16 Power tabs, the utility model is with reference to the IEC standard of 7/16 joint, the purport of design is in order to save cost, allow original antenna feeder transmit direct current, this 7/16 Power tabs can be docked with original 7/16 female on the antenna feeder, utilize 7/16 interface to make inner wire lead to galvanic positive pole, outer conductor leads to galvanic negative pole, forms DC channel.During installation leader cable passed large cable clip 14, inner core 13, large sealing packing ring 12 and be embedded in the afterbody of contact pin 5, form inner wire; The cable that newly increases is passed little cable clip 11, small sealing ring 10 until arrive at the bottom of blind hole 15, adopt spanner to screw part 9, make its end withstand on the cable surface that newly increases, thereby this cable is fixed, form outer conductor, here large cable clip 14, little cable clip 11 all want opposite shell 6 to screw to lock two cables, and swivel nut 1 end docks with the antenna feeder female.
