Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of radio-frequency (RF) coaxial terminate load, and it reduces costs, and shortens manufacturing time.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of radio-frequency (RF) coaxial terminate load, it is characterized in that, it comprises connection swivel nut, the first silica gel ring, insulator, rubber ring, housing, inner wire, screw, the second silica gel ring, ceramic resistor, end cap nut, housing comprises groove, escape and left end step, the first silica gel ring is positioned on left end step, rubber ring is positioned at groove, inner wire coordinates with the left end of ceramic resistor, the right-hand member of ceramic resistor and screw interference fit, inner wire and insulator compression fit form an assembly, the second silica gel ring is positioned at escape, connecting swivel nut is enclosed within on one end of housing, end cap spiro cap is on the other end of housing.
Preferably, described end cap nut is provided with a cavity.
Preferably, described housing inner side is provided with hangnail.
Positive progressive effect of the present utility model is: the utility model reduces costs, and shortens manufacturing time.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model radio-frequency (RF) coaxial terminate load.
Embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model radio-frequency (RF) coaxial terminate load comprises connection swivel nut 1, the first silica gel ring 2, insulator 3, rubber ring 4, housing 5, inner wire 6, screw 7, the second silica gel ring 8, ceramic resistor 9, end cap nut 10, housing 5 comprises groove 52, escape 54 and left end step 57, the first silica gel ring 2 is positioned on left end step 57, rubber ring 4 is positioned at groove 52, inner wire 6 coordinates with the left end of ceramic resistor 9, the right-hand member of ceramic resistor 9 and screw 7 interference fit, inner wire 6 forms an assembly with insulator 3 compression fit, the second silica gel ring 8 is positioned at escape 54, connecting swivel nut 1 is enclosed within on one end of housing 5, end cap nut 10 is enclosed within on the other end of housing 5.
End cap nut 10 is provided with a cavity 12.Housing 5 inner sides are provided with hangnail 51.
The manufacture process of radio-frequency (RF) coaxial terminate load is as follows:
Step 1, insulator 3 compression fit that are polytetrafluoroethylene by an inner wire 6 and material form an assembly; Housing 5 inner sides are provided with hangnail 51, and have straight burr on hangnail 51, prevent that insulator 3 and housing 5 from axial rotation and radial displacement occurring.
Step 2, on the left end step 57 of housing 5, joining first silica gel ring 2 seals, on the maximum outside diameter of whole housing, overlap one and connect swivel nut 1, then at a groove 52 of housing 5 outside processing, in groove 52, put a rubber ring 4 that plays fixed position effect.
Step 3, inner wire 6 coordinates a ceramic resistor 9, the left end 91 of ceramic resistor 9 and the fluting end tight fit of inner wire, screw 7 interference fit that 92 right-hand members of ceramic resistor and can adjustable ranges.The screw thread 53 of screw 7 and housing 5 screws and is engaged to suitable position.
Step 4 is joined second silica gel ring 8 in the escape 54 of the external screw thread end face of housing 5, then the screw thread 55 of end cap nut 10 and housing is torqued-up to motionless till.So far, this radio frequency coaxial load completes.
The utility model radio-frequency (RF) coaxial terminate load has following characteristics:
One, inner wire adopts the pole materials processing of tin bronze, elastic properties of materials is good, toughness is strong, and fluting is held the Elastic Contact of partly remaining valid for a long time that contacts with ceramic resistor, and service time is long, the wear-resisting wiping of bronze material, long-term plug rear surface wearing and tearing are little, and contact resistance variation is little, and electric property does not change substantially.
Two, what the other end of ceramic resistor was used is to rotate fixing screw 7, between screw 7 and ceramic resistor, adopts interference fit, and then torsion on demand, is tightened to corresponding position by screw threads, the risk that can avoid interference fit to cause ceramic resistor to damage.In addition, interference fit has Stress Release effect, has exposure risk.
Three, the right side trisection of screw 7, processing three diameters is that 2.0mm, the degree of depth are the hole 71 of 2.500 mm, and the convenient screwdrivers with three nails screw screw thread, has avoided burr that the way of traditional flat recess or cruciform slot screw causes the screw thread that spins etc. to be unfavorable for the way of assembling.
Four, a cavity 12 of end cap nut 10 processing, both can save rapidoprint; can increase the surface area of inner chamber again, when loading on work, temperature can raise; the temperature that can allow large surface area reduces faster, thereby has protected the whole load can be not damaged because of excess Temperature.
Five, on the external diameter of housing 5, process a groove 52, in groove 52, join a rubber ring, be fixedly connected with swivel nut 1, this kind of method materials are economized, without independent processing metal part, housing processing is simple, easy to assembly, because there is no Snap ring structure, without special tooling, assemble, the operation of simple hand, installation time can reduce 1/3, reduces costs, and shortens manufacturing time.
Above-described specific embodiment; the technical problem of solution of the present utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
