The invention relates to a novel electric power connector, comprising a screw sleeve, a casing, an insulator fixedly arranged in the casing, and a contact pin embedded in the insulator, wherein one end of the casing is screwed in the screw sleeve; a cylinder body which is coaxial with the contact pin and extends along a central shaft of the casing is arranged on the side surface at the other end of the casing; a thread is arranged in the surface of the cylinder body; one end part of the cylinder body is in a tapered structure; the end part of the cylinder body is embedded in a rear casing; the cylinder body and the rear casing are internally matched with each other through threads; a blind hole is arranged on the side surface of the casing and is in the same side with the cylinder body; the axis of the blind hole is in parallel with the axial central line of the contact pin; a screwing part penetrating through the casing is arranged above a section of blind hole, close to the bottom of the blind hole; the screwing part is vertically communicated with the blind hole; and a small seal ring and a small cable clip in threaded connection with the casing are fixedly arranged on the other section of blind hole in sequence. According to the novel electric power connector, the structure is simple, the novel electric power connector can be butted with an original mother connector on an antenna feeder, an optical cable can be connected into the electric power connector, and the cost on the mobile communication antenna feeder is reduced.
Description
Technical field
The present invention relates to a kind of novel electric power joint, be 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 photoelectricity mixing 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 novel electric power joint.
Summary of the invention
For addressing the above problem, the present invention provides a kind of novel electric power joint, and this novel electric power joint can dock with original female head on the antenna feeder, and can insert an optical cable, makes the cost of mobile communication antenna feeder part reduce.
For achieving the above object, the concrete technical scheme that the present invention adopted is:
A kind of novel electric power joint; Comprise that swivel nut, an end are threaded onto the interior shell of swivel nut, are fixed in the interior insulator of shell, are embedded in the contact pin in the insulator; Sealing ring and embedding spring are arranged between shell and swivel nut, have along the central shaft extension of shell and the cylinder coaxial, screw thread is arranged on the surface of said cylinder with contact pin in the other end side of said shell; End at said cylinder is cone structure; The end of said cylinder is embedded in the rear casing, and said cylinder cooperates with the internal whorl of rear casing, and there is a blind hole side with the cylinder homonymy on said shell; The axial centre line parallel of the axis of said blind hole and contact pin; Said blind hole near one section of its bottom above the part of screwing that passes shell is arranged, the said part of screwing communicates with blind hole is vertical, the little cable clip that is fixed with small sealing ring successively, is connected with outer casing screw at another section of said blind hole.
Between the other end side of the leading section of said rear casing and shell, the sealing ring that is placed in cylinder is arranged.
The head of said little cable clip has the flange of the side that may be stuck in shell.
Said screwing packing ring one is arranged between part and the shell.
Between part and the packing ring one packing ring two is arranged said screwing.
Said packing ring one is all plain washer with packing ring two.
The said part of screwing is a soket head cap screw.
The present invention is simple in structure, and this novel electric power joint can dock with original female head on the antenna feeder, and can insert an optical cable, makes the cost of mobile communication antenna feeder part reduce.

Wherein: swivel nut 1, sealing ring 2, embedding spring 3, insulator 4, contact pin 5, shell 6, cylinder 6-1, screw thread 6-2, packing ring 1, packing ring 28, the part 9 of screwing, small sealing ring 10, little cable clip 11, flange 11-1, rear casing 12, sealing ring 13, blind hole 14.
Embodiment
Give below and close accompanying drawing and embodiment is further described the present invention.
In Fig. 1～Fig. 3; A kind of novel electric power joint; 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 present embodiment sealing ring 2 employings between shell 6 and swivel nut 1; Have in the other end side of shell 6 along the central shaft extension of shell 6 and the cylinder 6-1 coaxial with contact pin 5; On the surface of cylinder 6-1 screw thread 6-2 is arranged; End at cylinder 6-1 is cone structure, and the end of cylinder 6-1 is embedded in the rear casing 12, and cylinder 6-1 cooperates with the internal whorl of rear casing 12.Between the other end side of the leading section of rear casing 12 and shell 6, the sealing ring 13 that is placed in cylinder 6-1 is arranged.
The blind hole 14 that the axial centre line parallel of one axis and contact pin 5 is arranged with the side of cylinder 6-1 homonymy on shell 6; Blind hole 14 near its bottom one section above the part 9 of screwing that passes shell 6 is arranged; Screw part 9 and blind hole 14 vertical communicating; Packing ring 1, packing ring 28 are arranged screwing between part 9 and the shell 6; Screw part 9 of present embodiment is soket head cap screw, and packing ring 1 is all plain washer with packing ring 28, the little cable clip 11 that is fixed with small sealing ring 10 successively, is threaded with shell 6 at another section of blind hole 14.
The head of little cable clip 11 has the flange 11-1 of the side that may be stuck in shell 6.
Present embodiment is to be example with 7/16 novel electric power joint; The present invention is with reference to the IEC standard of 7/16 joint, and the purport of design is in order to save cost, to let original antenna feeder transmit direct current; This 7/16 novel electric power joint can be docked with original 7/16 female head 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 is passed rear casing 12, cylinder 6-1 until the afterbody that is embedded in contact pin 5 to shell 6 inside, form inner wire; The cable that increases newly is passed little cable clip 11, small sealing ring 10 until the bottom of arriving at blind hole 14; Adopt the spanner part 9 of screwing; Make its end withstand on the cable surface that increases newly, thereby this cable is fixed, form outer conductor; Here rear casing 12, little cable clip 11 all want opposite shell 6 to screw to lock two cables, and swivel nut 1 end docks with the female head of antenna feeder.
