Further, the opening form for installing nutplate includes for rectangular or V-arrangement.
The installation nutplate is opening design, for multi-thread cable also cross using, while making antenna erection sequence
More flexible, antenna dismounting is more convenient.This design simultaneously can shield to the installation of antenna.The torque that installation nutplate is tightened
When excessive, automatic sliding teeth avoids damage to antenna.Advantage is as follows when use:
When cable 8 is more than 2, the N connector of the tail portion of cable can not pass through the installation nutplate that tradition is not open
This problem is not present using the design in centre bore.Such as ceiling mount antenna installation scenario is generally mounted on the buckle of furred ceiling, is detained
Plate opening diameter is slightly larger than the diameter of connecting screw but need to be less than installation nutplate outer dimension.When the antenna cable 8 needed to change
When more than 2, the cable diameter of 1 N connector diameter power-up cable 8 is greater than the diameter of bore of installation nutplate, installs nutplate
It can not remove, antenna is caused to can not be successfully taking-up, cable need to be cut, so that antenna is not reusable.The peace of the embodiment of the present invention
Loading nut plate can solve this problem.
Using the installation nutplate of opening design, do not influence to dismount process, such as can be first by the communications cable (such as antenna)
It is fixed with installation nutplate, connects other cables afterwards；First antenna can also be connect with other cables, after be put into designated mounting position
Set, then by antenna cable pass through installation nutplate opening, after tighten fixation.
Refer to the installation protective effect of antenna: when the torque that installation nutplate is tightened is excessive, opening design can make to pacify
The automatic sliding teeth of loading nut plate does not destroy connecting screw and installs the screw thread of nutplate.When torque is excessive, plastic part screw thread is easy to wear
It destroys.
The present invention proposes that the ground strip of the radiator is formed by material buckles of slotting, and one end of the ground strip
One is kept with radiator.
Further, the shell of the radiator, processing method uses drawing and moulding principle, by a flat metal material
Cylindrical portion is produced with drawing die, then produces conus portion, then stamp out outwardly projecting interconnecting piece in conus portion bottom,
And process the connecting hole at interconnecting piece center.
In embodiment, the integrated molding method of the radiator are as follows: the first step, using drawing and moulding principle, first by one
Flat metal material produces cylindrical portion with drawing die, then produces conus portion；Second step stamps out in conus portion bottom
Outwardly projecting interconnecting piece, and process the connecting hole at interconnecting piece center.
Further, the groove body of the radiator, processing method use stamping die, laser processing or other it is equivalent plus
Work method operates the conus portion designated position of radiator, processes ground strip outer dimension, and one end of ground strip with
Shell keeps one.Ground strip is then folded into required size to bending on the outside of radiator.
In embodiment, the ground strip forming method of the radiator are as follows: the first step, using stamping die, to the circle of radiator
Tapering designated position carries out punching press, goes out ground strip outer dimension, and remove extra material；Second step, by ground strip to radiator
Outside bending folds required angle.At 60 ° or other angles, the second bending is parallel with bottom plate 4 for first bending and bottom plate 4.
Attached drawing 10, attached drawing 11, attached drawing 12, the comparison of attached drawing 13 are it is found that groove body is to the horizontal and vertical of antenna set by the present invention
Surface radiation performance has optimization.
Attached drawing 10, attached drawing 11 are the embodiment of uniformly distributed 3 groove bodies, attached drawing 12, the embodiment that attached drawing 13 is fluting.Attached drawing 12
It is compared with attached drawing 10, the out-of-roundness index of horizontal directivity pattern, fluting embodiment is better than embodiment of not slotting；Attached drawing 13 and attached drawing 11
Angle index is directed toward in comparison, the vertical plane gain of height pattern, and fluting embodiment is better than embodiment of not slotting.
The above disclosure is only a preferred embodiment of the invention, cannot limit the right of the present invention with this certainly
Range, therefore according to equivalent variations made by scope of the present invention patent, it is still within the scope of the present invention.
