Frequency connector is that one group of Central Symmetry is distributed, and this mounting means, which not only improves, to be avoided installing caused stress secundly, is made
Stress is dispersed, is also beneficial to the integrally-built reliability of complete machine.
Technique fillet is provided between the first flange front end face and outer shell outer wall of this lightweight radio frequency connector, after second flange
Technique fillet also is provided between end face and outer shell outer wall；After such structure, gone out by simulation analysis in structure and be easiest to
By the position destroyed and carry out finishing optimizing for structure, technique fillet is added at shell dangerouse cross-section (can play reinforcement
The effect of muscle), to increase connector shell intensity.
The shell of this lightweight radio frequency connector uses extra super duralumin alloy material, and the density of material is 2.7g/cm3；Employ
The minimum extra super duralumin alloy material of proportion, as connector shell new material, through groping, testing, large-scale application, show that this is super
Duralumin, hard alumin ium alloy material is the excellent material for harsh force environment or strict loss of weight requirement, and the application of extra super duralumin alloy material solves
Determine loss of weight requirement, reached the purpose of lightweight, product weight is mitigated to about the 1/3 of like product.
The second flange of this lightweight radio frequency connector to the distance of outer casing back is assumed to be L, and the length of shell is assumed to be H,
Following ratio should be met：
L:H=(4.0~4.5):(7.0~7.3).
After such structure, this lightweight radio frequency connector is assumed to be L in the distance of second flange to outer casing back, outside
The length of shell is assumed to be H, L:H=(4.0~4.5):(7.0~7.3), this lightweight radio frequency company can be increased after meeting aforementioned proportion
Device anti-torsional strength is connect, in Materials Yield Limit safety coefficient within a predetermined range, fully meets the high intensity requirement of needs.
