Embodiment
Pluggable RCU mechanisms built in the present invention are further elaborated below with reference to specific embodiment, to right
Technical scheme makes more complete and clear explanation.
As Figure 1-3, built-in pluggable RCU mechanisms of the invention, including the guide rail shell 1 and RCU moulds that section takes the shape of the letter U
Block 2.A pair symmetrical guide grooves 4 and a pair of flights are provided with two relative side walls of guide rail shell.RCU modules
A pair of guide rails 6 being engaged with the guide groove are provided with 2, can by the mating connection of the guide rail 6 and the guide groove 4
Realize the plug of RCU modules, and the both sides of RCU modules 2 are locked using the not de- screw 5 of pine with guide rail shell 1, so as to prevent
Only RCU modules and the guide rail shell are come off, for example, when antenna in high space-time it is also ensured that extract operate when RCU modules
Do not drop.As shown in Figures 2 and 3, the flight includes extending horizontally to described lead near the first end of the guide rail shell
Chute near second end of rail shell and the end slot positioned at the second end.The sliding end of the not de- screw 5 of pine is installed and is limited in
Slided in the chute, and the fixing end of the not de- screw 5 of pine is fixedly connected and can be placed in described with the both sides of the RCU modules
In end slot.The bottom of the guide rail shell offers the screwed hole 3 for being fixed with antenna-reflected plate.As shown in figure 4, pass through spiral shell
The guide rail shell can be fixed on antenna-reflected plate by nail.
The built-in pluggable RCU mechanisms of the present invention are connected by the installation screwed hole of guide rail outer casing bottom with antenna-reflected plate
Together.The guide groove of the guide rail that RCU modules both sides are set and guide rail shell, which is connected, realizes plug function, easy to disassemble
RCU modules.When motor breaks down or program needs renewal, the not de- screw of pine can be turned on and plug out by built-in RCU
Replacing upgrading is carried out to refill up.
In the present invention, the guide rail shell uses aluminium alloy machine-shaping, and is set on the surface of the aluminium alloy
There is the wear-resisting film layer of insulation, it can guarantee that plug operation repeatedly remains to keep excellent pluggable property and insulating properties, can will be right
The intermodulation effects of antenna are reduced to floor level.Specifically, the aluminum alloy guide rail shell is made of aluminium alloy plate.It is first
First, forms on aluminium alloy plate the wear-resisting film layer that insulate by the method for electrophoretic painting, then the method shape by bending, extruding again
Into guide groove and flight.In order to prevent the wear-resisting film layer of insulation to be formed from rupture occurring in subsequent bending, extrusion process, become
Shape (surface resistivity of measurement drastically reduces) and influence its electrical insulation capability.Before electrophoretic painting, aluminium alloy plate is existed first
Handled in treatment fluid, to form middle metal oxide layer.The handling process of recommendation is：80~100 DEG C for the treatment of temperature
Under 5~30min is handled in treatment fluid, the thickness in the intermediate layer of formation is 2.0~5.0 μm；The treatment fluid contains 10~
50g/L Na2CO3, 2~10g/L tetrafluoroborate (such as sodium tetrafluoroborate), 1.0~2.0g/L diethanol amine, it is and remaining
The water of amount.The basic component of addition such as sodium carbonate and diethanol amine can form the oxide membranous layer of predominantly aluminium, and tetrafluoro
Borate can pass through the shape to its section with the element initial action such as the Mg in aluminium alloy and forming the surface of needle-like or column
Looks analysis can find that the length for the needle-like or column structure to be formed is 200-500nm.And among the metal oxide of the formation
Layer electric conductivity is good, does not influence follow-up electrophoresis coating technique.Wherein, the aluminium alloy is 6XXX series alloys, such as can
To select 6061 conventional types, 6063 types, 6066 types, 6082 types, 6A02 types, 6351 types.Preferably 6063 type aluminium alloys, such as
6063 aluminium alloys, 6063A aluminium alloys, 6463 aluminium alloys, 6763 aluminium alloys, 6963 aluminium alloys etc., most preferably 6063 aluminium alloys, its
Not only versatility good yield is big, and processing characteristics is excellent, the moderate performance requirement for being fully able to meet the present invention of mechanical property.
6063 aluminium alloy contain 0.20~0.60wt% Si, 0.45~0.90wt% Mg, 0~0.35wt% Fe, 0~
0.10wt% Cu, 0~0.10wt% Mn, 0~0.10wt% Cr, 0~0.10wt% Zn, 0~0.10wt% Ti,
And the Al of surplus and other inevitable impurity, and the summation of other impurities is not higher than 0.15wt%.Using above-mentioned place
Reason liquid is handled 6063 aluminium alloy, can be formed needle-like or column structure that length is 350-500nm, can significantly be carried
Bond strength between high-aluminium alloy and the electrophoretic painting film layer being subsequently formed, so as to which the bending then carried out can be subjected to
And extrusion process, and keep the stability and electrical insulating property of electrophoretic painting film layer.The electrophoretic coating of acrylic acid or fluorine-containing
For the business electrophoretic coating of maturation, by electrophoretic painting on the basis of the middle metal oxide layer of formation, formation
The thickness of electrophoresis film layer, which is 10~25 μm, can meet requirement.As exemplarily, using fluorine-containing electrophoretic coating
Under conditions of electrophoretic voltage is 50V, the electrophoresis film of 10~25 μm of thickness can be obtained after electrophoresis 20-100s, measurement can
The surface resistivity for obtaining film is 1013More than ohm, and after bending and extrusion process, in machining deformation than more serious
On the surface of guide groove and flight, its surface resistivity also can reach 5 × 1012It is more than ohm.And if not being initially formed gold
Belong to intermediate oxide layer and the directly acrylic acid or fluorine-containing film of above-mentioned 10~25 μ m-thick of electrophoretic painting, in machining deformation
10 can be often reduced to than its surface resistivity on the surface of more serious guide groove and flight7Even 106Hereinafter, can not
Meet the application requirement of the present invention.In addition, in advance using sour (such as inorganic acid HCl, HF) or alkali (NaOH, Na2CO3) roughening
Although processing can form 0.10~0.30 μm of surface roughness Ra, the acrylic acid subsequently formed or fluorine-containing electrophoresis
Film can not be through by bending and pressure processing, its surface on surface of the machining deformation than more serious guide groove and flight
Resistivity can often be reduced to 107Even 106Hereinafter, the electric conductivity for revealing metalloid is become.
For the ordinary skill in the art, simply the present invention is exemplarily described for specific embodiment,
Obviously present invention specific implementation is not subject to the restrictions described above, and is entered as long as employing the inventive concept and technical scheme of the present invention
The improvement of capable various unsubstantialities, or it is not improved by the present invention design and technical scheme directly apply to other occasions
, within protection scope of the present invention.
