Description

  The present invention belongs to the technical field of electrical connectors, and more particularly, to a USB (Universal Serial Bus) socket.

  In recent years, many digital products such as a mobile phone, a digital camera, and a portable HDD are often charged using a USB standard connection cable, or connected to a personal computer for charging and data exchange. In this process, it is necessary to insert a USB plug into a USB socket to realize circuit and communication connection. By the way, in the conventional technology, the USB 2.0 / USB3.0 standard is limited, so the structure design of the USB socket cannot be changed greatly, and the USB plug is inserted into the socket only on either the front or back side. Can not. Therefore, in actual use, there is a possibility that the USB plug and the socket may be damaged due to an inappropriate operation of the user, and at the same time, the connection between the two cannot be realized quickly and easily by the insertion method only on either the front or back side. . Therefore, there is a need for a USB socket that can realize both-side insertion and removal of a USB plug in conformity with the USB 2.0 / USB 3.0 standard.

  The present invention aims to provide a USB socket that is simple in structure and excellent in practicality. In the conventional technology, the USB socket can only be inserted on either the front or back side of the USB plug. Solve a problem.

In order to realize the above-described object, the technical solution according to the present invention is configured as follows. That is,
The USB socket includes a metal case, an insulating main body, and a plurality of pin terminals arranged in parallel in the insulating main body. A positive electrode pin and a negative electrode pin extend from each of the pin terminals, and the positive electrode pin is Projecting from the surface of the insulating body, the negative electrode pin extending to the axis of another pin terminal that is symmetrical to the pin terminal and projecting from the back surface of the insulating body,
The distance from the positive electrode pin to the upper surface of the metal case is equal to the distance from the negative electrode pin to the lower surface of the metal case.

  Preferably, each of the positive electrode pin and the negative electrode pin is provided with a smooth arc-shaped elastic portion.

  Preferably, a through hole is provided at a position corresponding to the positive electrode pin and the negative electrode pin in the insulating main body, and the elastic portion protrudes from the through hole.

  By adopting the above-mentioned technical solution, the USB socket according to the present invention improves the structure of the conventional USB socket in conformity with the USB 2.0 / USB 3.0 standard. A conductive pin structure having front and back duality is formed. Therefore, instead of the conventional method that can be inserted / removed only on either the front or back side, the USB plug can be smoothly inserted / removed on either side, and the practicality of the USB socket is greatly improved. The value of application is extremely high.

It is a schematic diagram which shows the whole structure of the USB socket concerning the Example of this invention. It is a schematic diagram which shows the structure of the pin terminal concerning the Example of this invention.

  Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. However, the present invention can be realized by various different embodiments limited or covered by the scope of the utility model registration request.

  As shown in FIGS. 1 and 2, the USB socket according to the present embodiment includes a metal case 10, an insulating main body 20, and a plurality of pin terminals 30, and the insulating main body 20 is included in the metal case 10. The body portion of the pin terminal 30 is mounted in the insulating body 20. From each pin terminal 30, a positive electrode pin 31 and a negative electrode pin 32 extend. The positive electrode pin 31 protrudes from the surface of the insulating body 20, and the negative electrode pin 32 protrudes from the back surface of the insulating body 20. At the same time, the distance from the positive electrode pin 31 to the upper side surface of the metal case 10 is equal to the distance from the negative electrode pin 32 to the lower side surface of the metal case 10. That is, each pin terminal 30 forms a conductive pin structure having front and back two-sidedness. Therefore, instead of the conventional method that can be inserted / removed only on either the front or back side, the USB plug can be smoothly inserted / removed on either the front / back side.

  In order to ensure a stable connection between the plug and the socket, a smooth arc-shaped elastic part is provided at a portion of the positive electrode pin 31 and the negative electrode pin 32 that contacts the conductive structure of the USB plug. Further, a through hole is provided at a position corresponding to the positive electrode pin 31 and the negative electrode pin 32 in the insulating main body 20, and the elastic portion protrudes from the through hole. Moreover, in order to satisfy the design requirements of different specifications, the elastic part may have a folded structure.

  In order to further describe the USB socket according to the present embodiment, as shown in FIG. 3, a 4PIN USB socket that is currently most widely used is taken as an example. The USB socket has a total of four pin terminals. In order to distinguish each pin terminal, an indicator code is given to each pin terminal. That is, pin terminals 300, 310, 320, and 330. Four pin terminals are arranged in parallel, and the pin terminals 300, 310, 320 and 330 all form positive pins 301, 311, 321 and 331 protruding from the surface of the insulating body 20, and the pin terminal 300 , 310, 320, and 330 form negative electrode pins 302, 312, 322, and 332 that extend further and protrude from the back surface of the insulating body 20. The negative electrode pin 302 extends to the axis where the positive electrode pin 331 is located. That is, the negative electrode pin 302 and the positive electrode pin 331 are configured to face each other. Similarly, the negative electrode pin 312 and the positive electrode pin 321 face each other, the negative electrode pin 322 and the positive electrode pin 311 face each other, and the negative electrode pin 332 and the positive electrode pin 301 face each other. Therefore, by inserting the USB plug into the socket, it is possible to realize the connection between the two regardless of the front and back of the USB plug.

  As described above, the USB socket according to this embodiment is improved in the structure of the conventional USB socket in conformity with the USB 2.0 / USB 3.0 standard, and the USB plug can be inserted / removed regardless of whether the user is front or back. Therefore, the practicality of the USB socket is greatly improved, and the value of its spread and application is extremely high.

  The above description is only a preferred embodiment of the present invention and does not limit the scope of the utility model registration request.
