Problems solved by technology

However, the surface of the USB shell formed by this process will have a small gap, which has the following disadvantages: 1. It affects the structural rigidity of the USB shell; 2. The USB shell forms a capacitance under the action of the electromagnetic field, thereby interfering Data transmission affects the stability of the signal; 3. Affects the appearance of the USB
However, due to the size limitation of the USB interface, the thickness of the seamless pipe needs to meet certain requirements, and there is no seamless pipe that can be mass-produced and can meet this requirement in the prior art

Embodiment Construction

[0027] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0028] Such as figure 1 , figure 2 As shown, the present invention discloses a rectangular tube 1 which can form a seamless USB shell for a USB connector after cutting and related processing.

[0029] The rectangular tube 1 includes a tube wall 10 with a uniform thickness, and the tube wall 10 is closed to form an inner cavity 11 . The outer contour of the rectangular tube 1 and the cross section of the inner cavity 11 are rectangular. In detail, the cross section of the rectangular pipe 1 is a rectangular ring structure with a rectangular inner cavity 11 inside. The tube wall 10 of the rectangular tube 1 does not have any gaps that affect the performance of the seamless USB case.

[0030] The thickness T of the tube wall 10 of the rectangular tube 1 is 0.30-0.35mm, the width W of the rectangular tube 1 is 12.00±0.05mm, and the height H of the ...

Abstract

The invention discloses a rectangular pipe. The rectangular pipe comprises a pipe wall with the uniform thickness, wherein the pipe wall is defined in a closed mode to form an inner cavity; the outer contour of the rectangular pipe and the section of the inner cavity are rectangular; the thickness of the pipe wall is 0.30-0.35mm. According to the rectangular pipe, the size requirement of a universal serial bus (USB) interface on thickness is met, so that a seamless USB shell can be formed by using cutting and related processes. Correspondingly, the invention also discloses a production process for producing the rectangular pipe. According to the process, the rectangular pipes can be produced in batches.

Description

technical field [0001] The invention relates to a rectangular tube for cutting to form a seamless USB case, and at the same time relates to a production process for forming the rectangular tube. Background technique [0002] With the rapid development of science and technology, various electronic products have been produced one after another, such as mobile phones, tablet computers, mobile hard drives, etc., which have become indispensable work and entertainment tools in life. Data transmission between various electronic products is generally connected through a USB data cable. The USB interface of the existing USB data cable usually includes a USB shell, a plastic core and a connecting terminal. The above-mentioned processing method of the USB shell is generally to punch a plate first, and then bend the plate after punching, so that the two edges of the plate merge into a rectangular tubular shape to form a USB shell. However, the surface of the USB shell formed by this p...
