Switching module of USB electrical connector

Abstract

The invention provides a switching module of a USB electrical connector. An insulating seat body on a base and a tongue portion of the USB electrical connector is used for a plurality of terminals of a terminal group to respectively penetrate terminal slots of the base and used for linkage faces of a plurality of signal terminals to extend to the surface of the tongue portion, welding portions of a plurality of terminals and welding sides of a plurality of signal terminals respectively extends out of the base, the insulating seat body is covered by a shielding housing, the shielding housing is provided with an assembly portion on one side of an accommodating space, the assembly portion is used for a shielding cover body of a switching device to be movably assembled, an insulating body and a plurality of switching terminals are arranged in the shielding cover body, and the abutting-against sides of the switching terminals can electrically abut against the linkage faces of a plurality of signal terminals to enable the switching device to be movably flipped on the shielding housing. The switching module can be used for switching application of different specifications of USB electrical connectors.

Description

technical field [0001] The invention relates to an adapter module of a USB electrical connector, especially an adapter module that can be easily replaced with USB electrical connectors of different specifications. The assembly part on the shielding side covered by the outer cover of the insulating seat body is used for movable installation. The transfer device, and after the transfer device is lifted off the assembly part, the signal transmission can be carried out through a plurality of transfer terminals, and the purpose of avoiding bursting phenomenon is achieved. Background technique [0002] With the advancement of electronic technology, many electronic and electrical products bring people comfort and convenience in work and life, and also lead people to rely more and more on the use of electronic and electrical products. Through the application and operation of various electronic signals, To control the operation and execution of electronic and electrical products, and...

Problems solved by technology

[0003] However, as the volume of various electronic products is designed towards light, thin, short, and small models, such as commonly used smart phones, tablet computers, desktop computers or notebook computers, electronic products can use In a space of limited size, if it is installed in conjunction with various types of transmission interfaces to facilitate electronic signal transmission, it will occupy the internal circuit layout space of electronic products, and also occupy the peripheral space of the body, resulting in the circuit layout of electronic products. And the space of the body is not enough to use, so it is impossible to install a variety of electrical connectors in the limited space of electronic products, and it will be limited by the specifications of the electrical connectors during use, causing inconvenience to users

[0004] The applicant of this case had filed an application for a Taiwan invention patent with the "USB electrical connector structure" on June 11, 2013. The application number is No. 102120771. Please refer to Figure 20 As shown, the outer part of the insulating base B and one side of the base B1 of the USB electrical connector A of the invention patent covers the shielding case C and the housing C1 respectively, and because the housing C1 completely covers the periphery of the base B1 , when the USB electrical connector A is mated with the opposite type of socket electrical connector D, the power transmission terminal inside the socket electrical connector D will first touch the surface of the shell seat C1, and then contact the power terminal B2 of the insulating seat body B Electrical contact, but when the power transmission terminal first touches the surface of the housing C1, there will be an instantaneous high current (or high voltage) burst phenomenon of the power transmission terminal, which will affect the instability of the electronic signal and power transmission between the electrical connectors It is also easy to cause a short circuit between the electrical connectors, and there is still room for improvement

[0005] Therefore, how to solve the problems and troubles of instantaneous high current or high voltage burst phenomenon when the electrical connectors are relatively plugged in, and the specifications of electronic products cannot be expanded and used, and the use is easily restricted, etc., is to engage in this The relevant manufacturers in the industry are eager to study the direction of improvement
