Description
Technical field
The utility model relates to a kind of electric connector, is meant a kind of electric connector of the USB3.0 of being used for specification especially.
Background technology
Along with people becoming clear day by day for the convenient application demand of electronic product, and then cause giving more sustained attention of each manufacturer, because each manufacturer is in order to improve the competitiveness of electronic product, therefore must constantly strengthen and expand the function of electronic product, therefore various electronic product is except towards compact external form, its structure and transmission speed also need constantly to increase, so that the user to be provided the convenience on manipulating.
Since electric connector is used to connect between electronic product or electronic product in signal transmission between each element, therefore the importance of electric connector on electronic product can not speech, therefore how each manufacturer is easy to assembling with electric connector when making, reduce assembly cost, can take into account simultaneously the effect of electric connector again, become and competed part between each manufacturer in succession.
In electric connector, USB connector also has maximum breakthrough, USB (Universal Serial Bus) USB is a universal serial bus that connects external equipment, uses on computers extensively, it is common specifications, also can be used on set-top box and the game machine, even many industrial instrumentations also are that USB not only can provide the peripheral equipment transfer of data by USB and computer binding, also can power, the characteristic of On-The-Go plug and play more can make the direct swap data of portable device.
From the beginning first of USB is the USB1.0 specification, its transmission speed is 1.5Mb/s, and in release USB2.0 specification in 1998, transmission speed then rises to 12Mb/s, and this specification is with in being widely used in electronic product, and the USB3.0 specification of present up-to-date release then more rises to transmission speed 5.0Gb/s, and it is more than 10 times of USB2.0 specification, because it is many that speed promoted more in the past, therefore become the following product of promoting of each manufacturer.
Therefore, but under the USB3.0 specification situation of product phase in future, how the USB3.0 product is reached the purpose of simple and easy manufacturing, more become each manufacturer and need the problem that overcomes badly.
See also the TaiWan, China utility model patent and announce the electric connector that the M357063 patent discloses a kind of USB3.0 specification, this electric connector is provided with the terminal storage tank in first body, make it be able to ccontaining the first terminal, when the first terminal is inserted in the terminal storage tank, its contact site then can be exposed to first body surface, and the first terminal rear end then bends a weld part; Also be provided with the terminal storage tank on second body, make it be able to ccontaining second terminal, the second terminal front end then forms an elastic contact part, and the rear end then bends a weld part; In addition, the second body both sides then are provided with a clamping part, make second body to be fastened on the holding section of first body by clamping part, the front end contact site of the elastic contact part of second terminal and the first terminal then places the top end surface of first body at this moment, the rear end weld part of the first terminal and second terminal is then arranged setting, and it is fixedly welded on the circuit board; First body and the second body outer rim are then covered to close and are fixed a metal shell, and the cover by metal shell closes to make between itself and body and forms the telecommunications interface.
Yet, because this electric connector terminal quantity is more, need respectively the first terminal and second terminal to be inserted in the terminal storage tank of first body and second body with the mode of assembling respectively, just can reach the purpose of manufacturing; Since under the more situation of number of terminals, its assembling process complexity, and electric connector is easier simultaneously takes place because of human factor causes the product quality condition of poor in assembling process; In addition, in said structure, this body is formed by first body and second body again, therefore, when the first terminal is assembled in after first body, second terminal group be loaded on second body, need assemble first body and second body again, cause electric connector to assemble the increase at worker station during fabrication, increase assembly cost.
In addition, because the first terminal and second terminal are all made by the mode that plugs assembling, and its transmission speed of USB3.0 specification improves more than ten times than USB2.0 specification product, therefore also can't pass through high-frequency test by assembling mode, even if the also bad problem of product-free is finished in its assembling, still have the situation that can't be applied to electronic product and take place.
This shows that above-mentioned existing electric connector still has many shortcomings, real non-one kindhearted design, and demand urgently being improved.
Every shortcoming that designer of the present utility model derives in view of above-mentioned existing electric connector is urgently to think to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, successfully electric connector of the present utility model is finished in research and development finally.
