Description
Technical field
The utility model is about signal connector, espespecially a kind ofly utilize ground strip to exert pressure and prevent the signal connector of short circuit, to prevent the elastic fatigue of multiple metal terminal in it, and the problem avoided electric short circuit occurs and damage related electronic device, therefore can not only guarantee to be electrically connected quality, more significantly can promote the fail safe in use, and extend the useful life of this signal connector.
Background technology
In recent years, flourish due to Information of Science and Technology and electronic industry, good and cheap and compact various electronic installation (as: flat computer, intelligent mobile phone, driving recorder ... Deng) become people's life and the upper indispensable important tool of work, most people is computer accustomed to using already, process daily life and all kinds of information in working, people are also grown with each passing day to computer application demand, therefore, conveniently people are between different electronic installation, mutual transfer information (as: document shelves, audio and video file, picture ... Deng), dealer usually can on various electronic installation, various types of signal connector is set, with the connecting line by correspondence, making can mutual swap date between multiple stage electronic installation.In the transmission standard of numerous connector, again with universal serial bus (Universal Serial Bus, hereinafter referred to as USB) the most universal, because the connector decapacitation of USB specification is transmitted outside message data, the active voltage of 5 volts and the electric current of 0.5 ampere also can be provided simultaneously, allow connect electronic installation on it need not external power supply again, the electric power smooth operation of the connector from USB specification can be utilized, therefore after USB 1.0 in 1996 formally releases, USB connector has become one of interconnective main specifications of various electronic installation.
At present, USB specification has been about to enter the transmission quantity that USB 3.1, USB3.1 not only increases voltage, electric current comprehensively, and owing to improving coding loss, therefore transmission speed significantly can be promoted to 10GB each second.In addition, compared to USB 1.0 ~ USB 3.0 specification in past, the USB Type-C connector construction completely newly delivered in USB 3.1 more has a great change, i.e. " configuration is symmetrical up and down ", therefore user need not pick out the positive and negative of USB Type-C plug especially, and can at random insert in corresponding USB Type-C socket, allow on using more directly perceived.
But, in order to reach all plug-in function of positive and negative, two groups of identical splicing ears must be configured in USB Type-C connector, that is, in the confined space that USB Type-C connector must use in traditional USB connector, additionally fill in another group splicing ear again, make the space that in USB Type-C connector, each interelement is spaced more narrow, therefore, certainly will easily because of the conductor (as: splicing ear in USB Type-C connector, ground strip and metal shell etc.) too close each other, and there is the situation of electric short circuit (Short circuit), not only can cause the damage of associated electronic components, more entail dangers to is to the safety of user's lives and properties, be obliged to go to pay attention to.
