Description

USB connector with protection function

Technical Field

The utility model belongs to the technical field of the USB connector, especially, relate to a USB connector with safeguard function.

Background

USB is the Universal Serial Bus (USB), the name of which is Universal Serial Bus. This is a new interface technology that has become widely used in the PC field in recent years. The USB interface has the characteristics of higher transmission speed, hot plugging support and connection of a plurality of devices. Has been widely adopted in various kinds of external devices. Currently, there are three types of USB interfaces: USB1.1 and USB2.0, and USB3.0, which has emerged in recent years. Theoretically, the transmission speed of the USB1.1 can reach 12 Mbps/second, the speed of the USB2.0 can reach 480 Mbps/second, and the USB1.1 can be downward compatible.

The Micro USB connector (Micro USB) is a portable version of the USB2.0 standard, smaller than the Mini-USB interface used in the current mobile phones, and the Micro USB is the next generation specification of Mini-USB, and is established by USB standardization organization us, standards Forum (USB-IF) on 4/1/2007. Micro-USB supports OTG, which is 5pin like Mini-USB. The definition of the Micro family includes Micro-B family slots used by standard devices; a Micro-AB slot used by OTG equipment; Micro-A and Micro-B plugs, as well as cables. The Micro series are unique in that they contain a stainless steel housing, and ten thousand plugging and unplugging are not a problem.

Most of the existing USB connectors are not provided with protective devices, so that the existing USB connectors cannot be waterproof and dustproof, and the service life is shortened.

SUMMERY OF THE UTILITY MODEL

The utility model provides a USB connector with safeguard function aims at solving the unable waterproof dirt-proof problem of current USB connector that proposes in the background art.

The utility model discloses a realize like this, a USB connector with safeguard function, including USB connector body, its characterized in that, the front end of the upper surface of USB connector body is formed with a ladder groove, the left and right sides of the front end of the upper surface of USB connector body is symmetrically formed with two bosss, every respectively be formed with a first cylinder through-hole on the boss, two be provided with a baffle between the boss, the top of baffle is formed with a second cylinder through-hole, two first cylinder through-hole with wear to be equipped with a round pin axle in the second cylinder through-hole, be formed with a rectangle recess around the front end of USB connector body, fixed mounting has a rectangle sealing washer in the rectangle recess, the baffle with USB connector body passes through the buckle and connects.

Furthermore, the buckle is made of modified ABS plastic materials.

Furthermore, the rectangular sealing ring is made of a perfluororubber material.

Furthermore, the pin shaft is in interference fit with the first cylindrical through hole, and the pin shaft is in clearance fit with the second cylindrical through hole.

Furthermore, the width of the buckle is 5-10 mm.

The utility model has the advantages that: through the cooperation between first cylinder through-hole, second cylinder through-hole, round pin axle and the baffle, can open the baffle and close, through the cooperation between baffle, rectangle sealing washer and the buckle, can be so that baffle and rectangle sealing washer in close contact with, waterproof dustproof can not cause the damage to USB connector body.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, a USB connector with a protection function includes a USB connector body 1, and is characterized in that a step groove 2 is formed at a front end of an upper surface of the USB connector body 1, two bosses 3 are symmetrically formed at left and right sides of the front end of the upper surface of the USB connector body 1, a first cylindrical through hole 4 is formed on each boss 3, a baffle 5 is arranged between the two bosses 3, a second cylindrical through hole 6 is formed at a top of the baffle 5, a pin 7 is penetrated into the two first cylindrical through holes 4 and the second cylindrical through hole 6, a rectangular groove 8 is formed around the front end of the USB connector body 1, a rectangular sealing ring 9 is fixedly installed in the rectangular groove 8, and the baffle 5 is connected with the USB connector body 1 through a buckle 10.

The buckle 10 is made of modified ABS plastic materials, the modified ABS plastic materials have good heat resistance, toughness and flame retardance, and when the USB connector body 1 is overheated, the performance of the buckle 10 cannot be affected.

The rectangular sealing ring 9 is made of a perfluoro rubber material, and the perfluoro rubber is high-temperature resistant and cannot influence the performance of the perfluoro rubber due to overheating.

Pin shaft 7 and first cylinder through-hole 4 interference fit,

pin shaft

7 and 6 clearance fit of second cylinder through-hole, and pin shaft 7 can be at the internal rotation of first cylinder through-hole 4.
