Utility model content
The utility model is for the problems referred to above, propose a kind of mesh grid coaxial cable crimping structure, can effectively improve radio frequency (RF) coaxial connector crimp with mesh grid coaxial cable after the axial force of connecting portion and moment of torsion, make crimping position more firm, not easily get loose, also strengthen the water resistance of connecting portion simultaneously, reduce the probability that electric fault occurs, improve security performance.
For solving above technical problem, the technical scheme that the utility model provides is:
A kind of mesh grid coaxial cable crimping structure, it is characterized in that, comprising: heat-shrink tube, aluminium hydraulic pressed connecting pipe, metallic sheath and coaxial cable, described coaxial cable is mesh grid coaxial cable, coaxial cable one end is pressure connection terminal, and the pressure connection terminal of described coaxial cable has outwardly directed cable shielding mesh; Described metallic sheath is hollow cutting ferrule, comprises pipe and bayonet socket, and described pipe is cylindrical, and described bayonet socket is positioned at metallic sheath front end, is truncated cone-shaped; The pressure connection terminal outer layer covers of described coaxial cable has metallic sheath, the pressure connection terminal of coaxial cable and metallic sheath interference fit, and the reverse turnup of the outwardly directed cable shielding mesh of the described pressure connection terminal from coaxial cable is also wrapped in the skin of the pipe of metallic sheath; Described aluminium hydraulic pressed connecting pipe is wrapped in the skin of cable shield, the mouth of pipe edge of aluminium hydraulic pressed connecting pipe and bayonet socket be for the bottom surface of truncated cone-shaped fits; Described heat-shrink tube parcel and aluminium hydraulic pressed connecting pipe, metallic sheath and coaxial outer.
Be different from the existing cable shielding mesh that makes and wrap up annular knurl shell, re-use the method for metallic sheath crimping cable gauze screen, the interference fit by metallic sheath and coaxial cable that the utility model proposes, the pressure connection terminal of coaxial cable just can be combined more closely before crimping, and during crimping, not only only cable shielding mesh is crimped, also coaxial cable is crimped on the inside simultaneously, the outer protection skin of coaxial cable is made to there occurs some metamorphosis, improve torsion and the axial force of coaxial cable pressure connection terminal, reduce the probability that coaxial cable gets loose; The reverse turnup of cable shielding mesh is also wrapped in the skin of the pipe of metallic sheath, not only reduce the probability that coaxial cable gets loose, improve the shielding properties of the pressure connection terminal of coaxial cable simultaneously, reduce because of crimping operation, make the pressure connection terminal of coaxial cable impaired, thus the possibility causing the pressure connection terminal shielding properties of coaxial cable impaired.
The beneficial effects of the utility model are:
A kind of mesh grid coaxial cable crimping structure that the utility model provides, the interference fit of metallic sheath and coaxial cable, the pressure connection terminal of coaxial cable just can be combined more closely before crimping, and during crimping, not only only to cable shielding mesh crimping, also coaxial cable is crimped on the inside simultaneously, makes the outer protection skin of coaxial cable there occurs some metamorphosis, improve torsion and the axial force of coaxial cable pressure connection terminal, reduce the probability that coaxial cable gets loose; The reverse turnup of cable shielding mesh is also wrapped in the skin of the pipe of metallic sheath, not only reduce the probability that coaxial cable gets loose, improve the shielding properties of the pressure connection terminal of coaxial cable simultaneously, reduce because of crimping operation, make the pressure connection terminal of coaxial cable impaired, thus the possibility causing the pressure connection terminal shielding properties of coaxial cable impaired, the truncated cone-shaped design of the bayonet socket of metallic sheath makes heat-shrink tube laminating after carrying out pyrocondensation operation tightr, also reduces the probability that coaxial cable gets loose; Pressure connection terminal after simultaneously affixed, metallic sheath, coaxial cable, close gap between cable shielding mesh and heat-shrink tube are S type, greatly reduce the possibility that infiltration occurs at crimping position, improve water resistance, reduce the probability that electric fault occurs simultaneously, improve security performance.
