Embodiment Construction

[0022] See Figure 1 to Figure 3 , The waterproof digital TV antenna with amplification function includes a main body 100, an inner shaft sleeve 200, a pull tube antenna 300, a front plug 400, a rear plug 500, a circuit board assembly 600 and an injection molded body 700. Among them, the main body 100, the inner shaft sleeve 200, the front plug 400 and the rear plug 500 are all injection molded.

[0023] The main body 100 has a hollow circular tube shape. The main body 100 is composed of an outer sleeve 110 and a support 120. One end of the support 120 is fixed to one end of the outer sleeve 110. The support 120 has a slot 121, and the support 120 defines an opening 122. The main body 100 may also be an integrally injection-molded hollow tube, one end of which is partially cut away to form a slot 121.

[0024] Please refer to image 3 To FIG. 6, the inner shaft sleeve 200 also has a hollow round tube shape, and the inner shaft sleeve 200 is inserted into the outer sleeve 110. ...

Abstract

The invention discloses a novel waterproof digital television antenna with amplifying function, which comprises a tube drawing antenna. The tube drawing antenna is arranged in a hollow-shaped inner shaft sleeve that one end is sealed. The inner shaft sleeve is arranged in a hollow-shaped main body part. The main body part is arranged with a circuit plate component mutually induced with the tube drawing antenna. An injection molded part sealing the main body part is injected and molded outside the main body part. Because the circuit plate component is not directly contacted with the tube drawing antenna, and the circuit plate component is mutually induced with the tube drawing antenna, and the circuit plate component is sealed in the main body part by the injection molded part, thereby reaching the waterproof function with good induction effect and strong signal reception.

Description

Technical field [0001] The invention relates to small household appliances, belonging to the field of radio technology, and specifically relates to an antenna with an amplification function for receiving digital television signals. Background technique [0002] At present, the digital TV signal receiving antennas on the market are all of a single shape, made of steel wire or copper pipe, with backward technology, poor reception signal, and not waterproof. Summary of the invention [0003] The purpose of the present invention is to provide a waterproof digital TV antenna with an amplifying function with good waterproof performance and strong received signal in response to the above-mentioned defects in the prior art. [0004] In order to achieve the above objective, the present invention provides a waterproof digital TV antenna with amplification function, including a pull tube antenna. The pull tube antenna is installed in a hollow inner shaft sleeve whose one end is sealed. The i...
