Abstract
The invention discloses a USB plugging apparatus. The USB plugging apparatus comprises a cavity. The cavity is internally provided with a USB joint; the bottom of the cavity is provided with four fixation clamping pins; the fixation clamping pins are symmetrically arranged at the two sides of the cavity; the back surface of the cavity is provided with a rectangular opening for a lead wire to penetrate; and the lead wire can be movably arranged in the rectangular opening. According to the USB plugging apparatus, the four fixation pins are arranged at the bottom of the cavity and are fixed on a circuit board through fixation screws so that the firmness of a USB connector is greatly improved. Besides, the back surface of the cavity is provided with the rectangular opening for the lead wire to penetrate, and the lead wire can be movably arranged in the rectangular opening such that the service life of the USB connector can be substantially prolonged.
Description
Technical field
The present invention relates to a kind of USB device, or rather, is a kind of USB plug assembly.
Background technology
USB device is a kind of very common communication connected mode, is widely used in the field such as computer, mobile phone.Existing USB connector, after using for a long time, joint can be become flexible, and causes user's operation that is difficult to peg graft, and even causes USB connector to be scrapped.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby a kind of USB plug assembly is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of USB plug assembly, comprise a cavity, in described cavity, be provided with a USB joint, the bottom of described cavity is provided with four fixing card bases, described fixing card base is arranged on the both sides of described cavity symmetrically, the back side of described cavity is provided with the rectangle opening running through for lead-in wire, and described lead-in wire is arranged in described rectangle opening movably.
As preferred embodiment of the present invention, described fixing card base comprises a flat stationary body, the top of described stationary body is respectively equipped with an engaging protrusion, is provided with an engaging groove between described engaging protrusion, and described engaging groove matches with a hold-down screw.
As preferred embodiment of the present invention, described cavity is that elastic alloy is one-body molded.
USB plug assembly of the present invention utilization is arranged on four fixing card bases of cavity bottom, and is fixed on circuit board by hold-down screw, has greatly improved the firmness of USB connector.In addition, the back side of cavity is provided with the rectangle opening running through for lead-in wire, because lead-in wire is arranged in described rectangle opening movably, and the useful life that can greatly improve like this USB connector.

Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
As shown in Fig. 1 to Fig. 4, a kind of USB plug assembly 1, comprise a cavity 2, in this cavity 2, be provided with a USB joint 3, the bottom of this cavity 2 is provided with four fixing card bases 4, this fixing card base 4 is arranged on the both sides of this cavity 2 symmetrically, and the back side of this cavity 2 is provided with for lead-in wire 5 rectangle openings that run through 21, and this lead-in wire 5 is arranged in this rectangle opening 21 movably.
This fixing card base 4 comprises a flat stationary body 41, and the top of this stationary body 41 is respectively equipped with an engaging protrusion 42, is provided with an engaging groove 43 between this engaging protrusion 42, and this engaging groove 43 matches with a hold-down screw.
This cavity 2 is that elastic alloy is one-body molded.
The USB plug assembly utilization of this invention is arranged on four fixing card bases of cavity bottom, and is fixed on circuit board by hold-down screw, has greatly improved the firmness of USB connector.In addition, the back side of cavity is provided with the rectangle opening running through for lead-in wire, because lead-in wire is arranged in described rectangle opening movably, and the useful life that can greatly improve like this USB connector.
Below only with an execution mode, mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to external more functional module simultaneously, thereby expands to greatest extent its function.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claims were limited.
