It is fixed in shell.
Radio frequency (RF) coaxial connector is a kind of coaxial transmission line, and one end is bma-k type adapter, and the other end is microstrip line.Two
Hold and be adapted to after radio frequency connector and wiring board interconnection, connect to the equipment such as signal source, load or antenna.During energising work,
Its outer conductor is grounded, and electric current passes through inner wire outer surface axial direction transmitting radio frequency signal, and it is a kind of distributed constant circuit, transmission
Tem mould, its internal electric field all the time perpendicular to electric current transmission direction, its characteristic impedance z0, can be calculated with formula (1):
In formula (1), εrFor the relative dielectric constant of dielectric, a is inner conductor outer diameter, and b is outer conductor internal diameter.
The adapter of the present invention is used for the connection of radiofrequency signal and transmission, using no float design it is ensured that same when plugging together
Axle degree, improves the reliability of radiofrequency signal interconnection system, meets space flight and aviation electronics towards miniaturization, high reliability, light
The demand that matter direction is developed.The roll riveting of shell two ends, in order to fixing plug pin assembly and insulating supporting it is ensured that shell plates in roll riveting
Layer gold does not fall off, and after Theoretical Calculation and test determine roll riveting, the fixing sexual satisfaction of product center contact requires.
Described contact head is made up of connection end and elastic tip, leans on the first fillet linking, institute between connection end and elastic tip
The connection end stated and elastic tip are integrally formed, and connection end afterbody has 10 ° of taper hole;Described elastic tip is by the first cylindrical section, cone
Platform section and the second cylindrical section composition, be connected by the second fillet and the 3rd fillet between the first cylindrical section and frustum section, frustum section and
Second cylindrical end is directly connected to, axial direction several notches uniform in described elastic tip.Contact head is designed to overall structure, bullet
The wall thickness at property end is designed to uniform sizes it is ensured that uniform wall thickness;Cylindrical section and frustum intersegmental employing round-corner transition, using beryllium-bronze
Excellent precision turning machine-shaping, then with numerical control machining center milling otch;In the afterbody of contact head connection end, design one section
10 ° of taper hole, when connecting, outer cone section engagement corresponding with bma-j type adapter (standard component), and also the 3rd fillet is
The axial diameter of lower is slightly less than the overall diameter of bma-j type adapter, connects in bma-k type adapter and the bma-j type of the present invention
When connecing device and plugging together, the elastic tip of contact head can be strutted by bma-j, so that contact head elasticity is pressed on bma-j type adapter it is ensured that
Under aerospace vibration condition, adapter outer conductor displacement very little (≤0.05mm) diametrically, improves the vibration resistance of contact head
Can, the protection worse inner wire of intensity is injury-free simultaneously.
For being further ensured that resistance to shock under the conditions of aerospace for the contact head, the outer wall of the 3rd fillet of contact head increases
Plus a reinforcing ring.The mechanics mode of operation of contact head script is cantilever beam, after increasing reinforcing ring, after adapter plugs together,
Under aerospace vibration condition, become similar simple beam structure, further enhance its shock resistance.
On material selects, consider that environmental resistance is good, as far as possible using the used material of aerospace product, pin groups first
The contact pin of part is processed using beraloy, and plated surface is firmly golden;Also it is cased with sheath outside contact pin component.In structure design,
