Problems solved by technology

[0007] However, when the tightening force P increases during the crimping operation, such as Figure 7B As shown, since the interior of the insulator 22 of the coaxial cable 20 is extremely squeezed, the core wire 21 is occasionally disconnected.

Abstract

A shield terminal includes a braided part crimping member. The shield terminal is connected to a coaxial cable including a core wire, an insulator covering an outer periphery of the core wire, a braided portion covering an outer periphery of the insulator, and an outer sheath covering an outer periphery of the braided portion . The knitted portion crimping member crimps and surrounds a knitted portion exposed portion formed by removing the outer sheath to expose the knitted portion. A wall portion of the braided portion crimping member that is in direct contact with the braided portion is formed with a circular hole so that in a state where the braided portion crimping portion is crimped to the braided portion exposed portion, the braided portion A portion enters the circular hole.

Description

technical field [0001] The present invention relates to a shield terminal for a coaxial cable having a braided portion crimping member connected to a braided portion of the coaxial cable through a crimping operation. Background technique [0002] A coaxial cable used to transmit high-frequency signals, such as an antenna wire, usually sequentially includes from the center to the outside: a core wire as a central conductor; an insulator as a dielectric covering the outer circumference of the core wire; a braid covering the outer periphery of the dielectric body; and an outer sheath (also referred to as an insulating sheath) covering the outer periphery of the braid. In the coaxial cable having this structure, a coaxial connector is provided at an end portion thereof in order to connect the coaxial cable to a device or a coaxial cable on the mating side. The coaxial connector has a shield terminal for electrically connecting the braided portion to the coaxial connector in a g...
