Specific implementation mode
Pluggable RCU mechanisms built in the present invention are further elaborated below with reference to specific embodiment, to right Technical scheme of the present invention makes more complete and clear explanation.
As shown in Figs. 1-3, built-in pluggable RCU mechanisms of the invention, including the guide rail shell 1 that takes the shape of the letter U of section and RCU moulds Block 2.A pair of symmetrical guide-track groove 4 and a pair of of flight are provided on two opposite side walls of guide rail shell.RCU modules A pair of and matched guide rail 6 of the guide-track groove is provided on 2, it can by the mating connection of the guide rail 6 and the guide-track 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 fallen off, such as the RCU modules when antenna is in high-altitude it is also ensured that when extracting operation It does not fall.As shown in Figures 2 and 3, the flight includes that described lead is extended horizontally near the first end of the guide rail shell Sliding slot near the second end of rail shell and the end slot positioned at second end.The sliding end that pine does not take off screw 5 is installed and is limited in Sliding in the sliding slot, and the fixing end that pine does not take off screw 5 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 offer for the fixed threaded hole of antenna-reflected plate 3.As shown in figure 4, passing 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 connect by the installation threaded hole of guide rail outer casing bottom with antenna-reflected plate Together.The guide rail of RCU modules both sides setting is connected with the guide-track groove of guide rail shell realizes plug function, easy to disassemble RCU modules.When motor breaks down or program needs update, the not de- screw of pine can be unscrewed and plug out by built-in RCU Replace upgrading and refill up.
In the present invention, the guide rail shell uses aluminium alloy machine-shaping, and is arranged on the surface of the aluminium alloy There is the wear-resisting film layer of insulation, the plug that can guarantee repeatedly, which operates, 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 being bent, squeezing again At guide-track groove and flight.Rupture occurs in subsequent bending, extrusion process, becomes for the wear-resisting film layer of insulation formed in order to prevent Shape (surface resistivity of measurement drastically reduces) and influence its electrical insulation capability.Before electrophoretic painting, exist first to aluminium alloy plate It is handled in treatment fluid, to form middle metal oxide layer.The treatment process of recommendation is：80~100 DEG C for the treatment of temperature Under 5~30min is handled in treatment fluid, the thickness of the middle layer of formation is 2.0~5.0 μm；The treatment fluid contains 10~ The Na of 50g/L2CO3, the tetrafluoroborate (such as sodium tetrafluoroborate) of 2~10g/L, the diethanol amine of 1.0~2.0g/L 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 react and be formed needle-shaped or columnar surface with elements startings such as Mg in aluminium alloy, pass through the shape to its section Looks analysis can find that needle-shaped or column structure the length to be formed is 200-500nm.And among the metal oxide of the formation Layer electric conductivity is good, does not influence subsequent electrophoresis coating technique.Wherein, the aluminium alloy is 6XXX series alloys, such as can To select common 6061 type, 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, Not only versatility good yield is big, but also processing performance is excellent, the moderate performance requirement for being fully able to meet the present invention of mechanical property. 6063 aluminium alloy contain the Si of 0.20~0.60wt%, the Mg of 0.45~0.90wt%, the Fe of 0~0.35wt%, 0~ The Ti of the Cu of 0.10wt%, the Mn of 0~0.10wt%, the Cr of 0~0.10wt%, the Zn of 0~0.10wt%, 0~0.10wt%, 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 6063 aluminium alloy is handled, can formation length be 350-500nm needle-shaped or column structure, can significantly carry Bond strength between high-aluminium alloy and the electrophoretic painting film layer being subsequently formed, 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 ripe business electrophoretic coating, 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 illustratively, 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 1013Ohm or more, and after bending and extrusion process, it is more serious in machining deformation On the surface of guide-track groove and flight, surface resistivity also can reach 5 × 1012Ohm or more.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 Its surface resistivity can often be reduced to 10 on the surface of more serious guide-track groove and flight7Even 106Hereinafter, and cannot 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 the surface of the more serious guide-track groove of machining deformation and flight Resistivity can often be reduced to 107Even 106Hereinafter, becoming the electric conductivity for revealing metalloid.
For the ordinary skill in the art, specific embodiment is only exemplarily described the present invention, Obviously the present invention specific implementation is not subject to the restrictions described above, as long as use the inventive concept and technical scheme of the present invention into The improvement of capable various unsubstantialities, or it is not improved by the present invention design and technical solution directly apply to other occasions , within protection scope of the present invention.
