DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] like Figures 1 to 5 As shown, an elongated flexible rod antenna includes a connector A, the tail of which is connected to a coaxial cable D and a hollow cable C that is sleeved over the coaxial cable D. The coaxial cable D is connected to a circuit board H, which is connected to a spring I. The outer end of the spring I is connected to a flexible axis E. Both the spring I and the flexible axis E are made of flexible materials and have flexibility when connected as a whole.

[0023] The circuit board H is fixed on a transfer sleeve G.

[0024] One end of the hollow cable C is fixed by riveting with a first copper tube F1. The hollow cable C is composed of an insulating material, a shielding material and an outer skin. From the outside to the inside, it is an outer skin-shielding layer-insulating layer, and the whole is a flexible material. The first copper tube F1 is riveted to one side end of the adapter sleeve G. In this embodiment, one side end of the adapter sleeve G is provided with a first extension portion similar to a shaft shoulder, and the first copper tube F1 is sleeved and riveted on the first extension portion. The other side end of the adapter sleeve G is also provided with a second extension portion similar to a shaft shoulder, and a slot is provided on the second extension portion. The circuit board H is first inserted into the slot for pre-positioning, and then the two are welded together. The coaxial cable D is inserted from one side end of the adapter sleeve G and welded to the circuit board H.

[0025] The spring I passes through the other side end of the adapter sleeve G and is connected to the circuit board H.

[0026] A second copper tube F2 is provided at the connection between the spring I and the flexible axis E for riveting and fixing.

[0027] The connector A, hollow cable C, adapter sleeve G and spring I are covered with a first plastic shell B1, the flexible axis E is covered with a second plastic shell B2, and the end of the second plastic shell B2 is covered with a plastic cap B3.

[0028] The first plastic shell B1 and the second plastic shell B2 are injection-molded TPE materials. This material is a soft rubber material with the protective properties of plastic and can bend when subjected to external forces without being easily broken.

[0029] The middle main body portion of the adapter sleeve G is an I-shaped hollow structure, and the two side ends of the middle main body portion are respectively a first extension portion and a second extension portion, which are used to insert the coaxial cable D through the middle hollow position.
