Abstract

The invention relates to a power joint. The power joint comprises a threaded sleeve, a housing with one end screwed into the threaded sleeve, an insulator fixed in the housing and a contact pin embedded into the insulator, wherein a large seal ring, an inner core and a large cable clamp in threaded connection with the housing are sequentially fixed into the other end of the housing and coaxial with the contact pin; the inner core is provided with a clamp edge extending axially and embedded into the large cable clamp; a blind hole is formed in the side surface of the side of the housing, where the large cable clamp is arranged; the axis of the blind hole is parallel with the axial center line of the contact pin; a screwing piece penetrating the housing is arranged above one segment of the blind hole close to the bottom, and perpendicularly communicated with the blind hole; and a small seal ring and a small cable clamp in threaded connection with the housing are sequentially fixed at the other segment of the blind hole. The power joint has a simple structure and can be butted with a female contact originally arranged on an antenna feeder; and an optical cable can be accessed into the power joint, so that the cost of the mobile communication antenna feeding part is lowered.

Description

A kind of Power tabs

Technical field

The present invention relates to a kind of Power tabs, 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 Power tabs.

Summary of the invention

For addressing the above problem, the present invention provides a kind of Power tabs, and this Power tabs can be docked 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 Power tabs; Comprise that swivel nut, an end are threaded onto shell in the swivel nut, are fixed in insulator in the shell, are embedded in the contact pin in the insulator, sealing ring and embedding spring are arranged between shell and swivel nut, the big cable clip that in the other end of said shell, be fixed with large sealing packing ring, inner core successively, is connected with outer casing screw; Said large sealing packing ring, inner core, big cable clip are coaxial with contact pin; Said inner core has the edge that extends vertically, and said edge is embedded in the big cable clip, in the side of said shell and big cable clip homonymy one blind hole is arranged; 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.

The head of said big cable clip has the flange of the side that can be stuck in shell, and the head of said little cable clip has the flange of the side that is stuck in shell.

Said screwing packing ring one is arranged between part and the shell.

Further, 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 Power tabs can be docked with original female head on the antenna feeder, and can insert an optical cable, makes the cost of mobile communication antenna feeder part reduce.

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, the part 9 of screwing, small sealing ring 10, little cable clip 11, flange 11-1, large sealing packing ring 12, inner core 13, edge 13-1, big cable clip 14, flange 14-1, blind hole 15.

Embodiment

Give below and close accompanying drawing and embodiment is further described the present invention.

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 present embodiment sealing ring 2 employings between shell 6 and swivel nut 1; The big cable clip 14 that in the other end of shell 6, be fixed with the large sealing packing ring 12 coaxial, inner core 13 successively, is threaded with shell 6 with contact pin 5; Inner core 13 has the edge 13-1 that extends vertically, and edge 13-1 is embedded in the big cable clip 14.

The blind hole 15 that the axial centre line parallel of one axis and contact pin 5 is arranged in the shell 6 and the side of big cable clip 14 homonymies; Blind hole 15 near its bottom one section above the part 9 of screwing that passes shell 6 is arranged; 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; 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 15.

The head of big 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.

Present embodiment is to be example with 7/16 Power tabs; 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 Power tabs 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 passed big 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 increases newly is passed little cable clip 11, small sealing ring 10 until the bottom of arriving at blind hole 15; 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 big 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 female head of antenna feeder.
