Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be noted that the drawings of the present invention are simplified and use non-precise ratios, and are only used for the purpose of facilitating and clearly assisting the description of the embodiments of the present invention.
As shown in fig. 1, the utility model provides a radio frequency pencil that can repeatedly bend, include:
a flexible tube composed of a spring 20 and a winding tape 30 coated on the surface of a tubular spring 20;
the micro-coaxial cable 10 is arranged at the hollow position of the spring 20, one end of the micro-coaxial cable 10 is connected with a first coaxial connecting end 41, the other end of the micro-coaxial cable 10 is connected with a second coaxial connecting end 42, and waterproof glue 50 is arranged at the connecting position of the micro-coaxial cable 10 and the coaxial connecting ends (41 and 42) for coating;
at least one coaxial connecting fixed seat 60 is connected with the flexible pipe to form a connecting seat of the coaxial connecting ends (41, 42), the coaxial connecting fixed seat 60 is in threaded connection with other structural parts to form protection, the connecting strength of the radio frequency wire harness and other structural parts is enhanced, and the coaxial connecting ends (41, 42) are prevented from being separated from other structural parts during assembly;
and the mark part 70 is arranged at one end of the coaxial connecting fixing seat 60.
In one embodiment, as shown in fig. 1, the micro-coaxial cable 10 is spirally disposed in the spring 20, so that the micro-coaxial cable 10 can have a certain stretching space. In the process of rotating or stretching the flexible pipe, the tubular structure of the spring 20 can prevent the coaxial cable 10 from being damaged by external structures, meanwhile, the structure of the spring 20 has certain pressure resistance to prevent the coaxial cable 10 from being damaged by clamping, and the winding belt 30 can also form a shield to prevent the coaxial cable 10 from being exposed when covering the surface of the spring 20.
In addition, annular grooves (not shown) are provided on the two coaxial connection ends (41, 42), in which a waterproof sealing ring 90 is mounted, so that the coaxial connection ends form a seal when assembled with other structural members, preventing moisture from entering the connection and contacting the micro coaxial cable 10.
In addition, the winding band 20 is a stainless steel winding band to obtain a strong structural strength, and the tensile and compressive capacity of the flexible pipe can be enhanced by winding the winding band on the surface of the spring 20.
In the above structure, the fixing device further includes a fixing portion (not shown), the fixing portion is solidified on the two coaxial connecting ends (41, 42) through structural adhesive, a groove is formed on the fixing portion, and the coaxial connecting fixing seat 60 is movably disposed on the groove, so that the coaxial connecting fixing seat 60 can rotate relative to the fixing portion. When the coaxial connection fixing base 60 is connected with other structures, the rotation of the coaxial connection fixing base 60 will not be linked with the rotation of the coaxial connection ends (41, 42), thereby avoiding the deformation of the flexible tube or the micro coaxial cable 10 caused by the rotation. Specifically, the coaxial connecting fixing seat 60 is provided with an internal thread in threaded connection with other structural members.
As shown in fig. 2, the coaxial connection fixing base 60 is preferably provided with a waterproof gasket 80, so as to form a seal for the coaxial connection end when being connected with other structures, and the coaxial connection end is matched with a sealing ring 90, so that the micro coaxial cable 10 can obtain better waterproof performance.
Preferably, the surface of the radio frequency wiring harness is provided with a baking paint layer.
It will be apparent to those skilled in the art that various changes and modifications may be made to the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
