Abstract
The utility model discloses a USB plug, which is mainly provided with a rectangular frame of which the upper part is cut in a U shape to form a fastening elastic sheet, and the inner part of the frame is provided with contact terminals side by side, wherein, the bottom edge of one side of the opening of the front edge of the frame is provided with an inclined chamfering to compose the USB plug. When the USB plug is inserted, due to the guide of the chamfering, the USB plug prevents being reversely inserted so as to raise the practicability of the plug and make the plug be quickly and conveniently inserted.
Description
Technical field
The utility model relates to a kind of USB plug, refers to a kind of anti-misoperation device that has especially, the USB plug that causes product to damage to avoid plug oppositely to misplug.
Background technology
General USB plug is typically provided with a frame shape pedestal, and most terminals side by side are set in pedestal, contacts the transmission that constitutes signal, power supply with the conductive hole of another socket by terminal when pegging graft.Known USB plug is because positive and negative are identical, therefore, misplug as if careless slightly just may the causing oppositely of user during grafting, cause signal to transmit, severe patient causes the damage of product, so, how to improve the structure of USB plug, can correctly peg graft under the aforethought situation in not needing for the user, real be the problem that the dealer institute utmost point of USB plug is thought the research and development solution.
Summary of the invention
The purpose of this utility model is to provide a kind of USB plug, makes USB plug be able to correctly peg graft under quick situation, prevents from oppositely to misplug the damage that causes product.
The purpose of this utility model is achieved in that a kind of USB plug, be provided with the framework of a rectangular shape, surface, framework top is provided with the engaging shell fragment with the cutting of U shape, be provided with a base in the framework, base is provided with spaced most terminal, and the wherein root edge of a side of the opening of framework is provided with intilted chamfering.
Described USB plug, the oblique shape chamfering of being located at framework opening root edge is located at the left side or the right side of opening.
Description of drawings
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a stereogram of the present utility model.
Fig. 2 a is a vertical view of the present utility model.
Fig. 2 b is a front view of the present utility model.
Fig. 3 is that illustration is implemented in use of the present utility model.
Embodiment
Please consult simultaneously shown in Fig. 1 and Fig. 2 a and Fig. 2 b, the utility model mainly is provided with a frame shape framework 1, surface, top in framework 1, be provided with the U shape and cut formed engaging shell fragment 11, the inside of framework 1 then is provided with a base 12, establishes with spaced most terminals 13, wherein in base 12, one side of the root edge of the front openings of framework 1 is made as inside oblique shape chamfering 14, with the USB plug 100 that constitutes a tool anti-misoperation device.
Combination by aforementioned components, USB plug 100 is when pegging graft, chamfering 14 wherein can constitute correct direction guiding, prevent that plug 100 is reversed grafting, cause signal to transmit or the product infringement, tiltedly shape chamfering 14 can be located at the left side or the right side of opening root edge, can constitute equally to prevent the effect that oppositely misplugs.
As shown in Figure 3, when the utility model uses in reality, because a side of the opening root edge of framework 1 is provided with inside oblique shape chamfering 14, if direction is opposite when therefore pegging graft, USB plug 100 can't be plugged in socket 2 smoothly; Otherwise, if in the right direction, then by the guiding of chamfering 14, plug 100 gets final product correct and socket 2 is pegged graft mutually, and so, chamfering 14 forms an anti-misoperation device, can prevent effectively that USB plug 100 is reversed misplugs, and then can prevent that the product that is connected from damaging because of mispluging.
In sum, the utility model is established with inside oblique shape chamfering in opening root edge one side of USB plug, to constitute anti-misoperation device, prevent from that USB plug is reversed to misplug, and be the design of a practicality.
Claims (2)
1, a kind of USB plug, be provided with the framework of a rectangular shape, surface, framework top is provided with the engaging shell fragment with the cutting of U shape, is provided with a base in the framework, base is provided with spaced most terminal, it is characterized in that: the wherein root edge of a side of the opening of framework is provided with intilted chamfering.
