Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1, the utility model relates to a butt joint structure suitable for between unidimensional radio frequency coaxial cable, including the joint inner conductor 31 of reducing, surround in the joint medium body 32 that connects outside the joint inner conductor 31 and surround in the joint outer conductor 33 that connects outside the medium body 32, the thin end inboard that connects inner conductor 31 has the little concave cavity 311 of pegging graft with thin coaxial cable's first inner conductor 11, the thick end inboard that connects inner conductor 31 has the big concave cavity 312 of pegging graft with thick coaxial cable's second inner conductor 21, the outside that connects outer conductor 33 is the taper shape, the thin end that connects outer conductor 33 welds with thin coaxial cable's first outer conductor 13, the thick end that connects outer conductor 33 welds with thick coaxial cable's second outer conductor 23. The joint medium body 32 is used to ensure that the joint inner conductor 31 and the joint outer conductor 33 are not directly conducted. The thin coaxial cable has a first dielectric body 12 that does not directly connect the first inner conductor 11 to the first outer conductor 13, and the thick coaxial cable has a second dielectric body 22 that does not directly connect the second inner conductor 21 to the second outer conductor 23. When the coaxial cable is used, two radio-frequency coaxial cables with different sizes are connected by one middle part, wherein the inner conductor is exposed out of the corresponding medium body and is conducted with the joint inner conductor 31 in a splicing mode, and an enough gap is reserved between the outer conductor of the coaxial cable and the joint outer conductor 33 to be connected through solder, so that the coaxial cable is easy to mount and is not easy to damage. The joint outer conductor 33 may be made of a material that facilitates soldering of tin and lead, such as gold plating of brass, tin plating of red copper, and the like. The butt joint structure only needs one group of parts for transition, and is simple in structure and very small in signal distortion. Because the transition of the outer side of the outer conductor of the connector is smooth, auxiliary materials such as a waterproof sleeve can be easily sleeved on the outer side of the outer conductor of the connector for multi-directional protection. The flexible cable butt joint device is easy to wire and suitable for butt joint among flexible cables, rigid cables and rigid cables. The above-mentioned medium body is preferably made up by using engineering plastics with excellent electric properties of solid PTFE, PI and PEEK, etc.
As shown in fig. 1, the thin end of the joint outer conductor 33 is provided with a first solder hole (not labeled) for filling solder 4a, the solder 4a integrally welds the inner side of the joint outer conductor 33 and the outer side of the first outer conductor 13, and the first solder hole is provided with two opposite first solder holes. The first solder hole allows the solder 4a to directly diffuse from the inside of the joint outer conductor 33 to the outside, causing the solder 4a to fill the gap. The two first welding holes can avoid impedance unevenness caused by diffusion and gas trapping of the welding flux 4a, and influence on connection performance.
As shown in fig. 1, the thick end of the joint outer conductor 33 is provided with a second solder hole (not labeled) for filling solder 4b, the solder 4b integrally welds the inner side of the joint outer conductor 33 and the outer side of the second outer conductor 23, and the second solder hole is provided with two opposite solder holes. The second solder hole allows the solder 4b to diffuse directly from the inside of the joint outer conductor 33 to the outside, causing the solder 4b to fill the gap. The two second solder holes can avoid impedance unevenness caused by diffusion and gas trapping of the solder 4b, and influence on connection performance.
The outer walls of the small concave cavity 311 and the large concave cavity 312 are both of a multi-petal elastic structure. The joint inner conductor 31 can be made of beryllium bronze, tin phosphor bronze and other elastic materials, and the multi-petal structure can generate certain clamping force on the inner conductor of the radio frequency cable, so that the multi-petal structure is suitable for size change of the inner conductor within a certain range, and conductive connection is ensured.
As shown in fig. 2, the outer wall of the joint inner conductor 31 is provided with a barb 313 for catching the joint medium body 32. The inner side of the joint inner conductor 31 and the inner side of the joint dielectric body 32 are closely stepped, and the barb 313 prevents the both from coming off.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
