Description

  The present invention relates to a universal serial bus connector.

  In today's days when science and technology are making dramatic progress, electronic devices are more widely applied in daily life and used for processing various tasks. Further, as a transmission method between various electronic devices, by connecting a connector having a transmission cable, each electronic device can transmit information and data to each other. Therefore, the transmission speed is very important in the transmission process of each electronic device.

  Currently, there are serial connector types that conform to the standards of Universal Serial Bus (USB) connectors 1.1 and 2.0, and their transmission speeds are 1.5 Mbit / s and 480 Mbit. / S. However, since the amount and capacity of data that needs to be transmitted by the electronic device is increasing, the transmission speed of the conventional connector is insufficient. Therefore, new research and development have been conducted on connectors capable of high-speed transmission.

  For example, the universal serial bus connector 3.0 has a transmission speed of 5 Gbit / s and is backward compatible with the conventional universal serial bus connector 1.1 or 2.0. Therefore, the current universal serial bus connector 3.0 takes a form in which another connection terminal is newly mounted while holding the conventional connection terminal as it is.

  As described above, the universal serial bus connector 3.0 includes two sets of different connection terminals, and is currently formed by the following manufacturing method. That is, first, a conventional terminal part and a new terminal part are formed by using different press dies for the conventional terminal and the new terminal and cutting different conductive pieces. Furthermore, after bending each, the conventional terminal part and the new terminal part are put into the mold, respectively, are molded by insert injection, or each is fitted and fixed to the insulating base, and then this semi-finished product is further protected By housing in a case, a connector conforming to the universal serial bus connector 3.0 is formed.

  However, the above-mentioned method for manufacturing the universal serial bus connector has the following drawbacks.

(1) The conventional 1st terminal part and 2nd terminal part are mutually parallel, exhibit the structure laminated | stacked up and down, respectively, and are fixed to the insulation base. As described above, the first terminal portion and the second terminal portion must be manufactured separately, and it is necessary to develop different press dies and to cut the conductive pieces by the respective press dies. There was a problem of increasing the cost and time of mold development.

  (2) The conventional 1st terminal part and 2nd terminal part are manufactured separately, and are each fixed to the insulation base, after cutting a different conductive piece, respectively. For this reason, when mass-produced, the waste material becomes very large, and the material cost and the assembly cost further increase due to the method in which the first terminal portion and the second terminal portion are fixed to the insulating base. The manufacturing process becomes more complicated and the manufacturing time increases.

  The present invention has been made to solve the above-mentioned problems, and its purpose is to cost and time for mold development by separately manufacturing the first terminal portion and the second terminal portion of the prior art. It is an object of the present invention to provide a universal serial bus connector capable of suppressing the increase in the number of buses.

  In the present invention, the connection end portions of the first terminal portion and the second terminal portion are each provided with an interval and are arranged in an interval form, and the first terminal portion and the second terminal portion have respective base portions. A cut surface corresponding to the pierce hole of the insulating base is provided on one adjacent side. In the manufacture of the first terminal portion and the second terminal portion, the first terminal portion and the second terminal portion are formed by being pressed into a single conductive piece only by a single press die. By connecting them with at least one or more bridges, the two are fixed to the insulating base at the same time, and further, the cut surfaces are formed by removing the bridges through the piercing holes after the mounting is completed.

  As described above, according to the present invention, since a method of pressing a single conductive piece with a single press die is adopted, the cost of developing the die is reduced, and the material is saved and the assembly process is simplified. As a result, time and complexity in manufacturing can be reduced.

  In another aspect of the present invention, a support base is added to one side of the insulating base, and after the first terminal portion and the second terminal portion are mounted on the insulating base, the support base becomes the first terminal portion. And the second terminal portion are pressed so that the soldered end portions of both are coplanar, and the soldered end portions are securely soldered to an external transmission cable or a predetermined circuit board.

(Effect of device)
In the present invention, in particular, a cut surface corresponding to the pierce hole is provided on one side adjacent to each of the base portions of the first terminal portion and the second terminal portion, whereby a single conductive piece is formed by a single mold. It is molded by pressing and fixed inside the insulating base by a single process, thereby reducing the development cost of the mold, realizing the effects of saving material and simplifying the manufacturing process.
