Signal connector assembled using trapezoidal blocks

The present invention is a signal connector assembled by a trapezoidal block, in particular, a plurality of trapezoidal blocks can stably and quickly assemble and position a reinforcing plate base and a plurality of terminal blocks into an assembled tongue plate. The assembled tongue can be assembled into the metal housing in a state in which the sheets are assembled and positioned in each of the terminal blocks to effectively improve assembly convenience and efficiency.

According to the connector, the connector refers to all the connecting components and their accessories that are applied to the electronic signal and the power supply. It is also a bridge between all the signals, and its quality will not only affect the reliability of current and signal transmission. It will also affect the quality of the operation of the entire electronic machine. Among the transmission specifications of many connectors, Universal Serial Bus (USB) is the most popular, because USB is more parallel than parallel (such as EPP, LPT), serial port (such as RS-232). Such as traditional computer standard bus transfer speed is much faster, and the USB specification connector can provide hot plug (plug plug) and plug-and-play (Plug-n-Play) function, allowing users to USB devices can be connected to various USB devices (such as keyboard, mouse, hard disk, printer, digital camera, etc.) without rebooting. Therefore, since USB 1.0 was officially launched in 1996, USB connection The device has become one of the main specifications for interconnecting various electronic devices.

With the gradual evolution of USB technology, USB specifications from USB1.0, USB2.0, and USB3.0 have now fully entered USB 3.1. USB3.1 not only improves the transmission of voltage and current. The transmission, and because of the improved coding loss, can greatly increase the transmission speed to 10GB per second. In addition, compared to the previous USB1.0~USB 3.0 specification, a new Type-C interface has been added to USB 3.1. The Type-C connector structure has a major change compared to other interface connectors. "The configuration is symmetrical up and down", meaning that the user will not need to specifically identify the front and back of the USB 3.1 plug, but can be arbitrarily inserted into the corresponding USB 3.1 socket, which is more convenient to use.

However, in order to achieve the function of plugging both the front and the back, the USB 3.1 connector must be equipped with two sets of identical connection terminals, and the connector has a metal casing, a metal plate, a grounding piece and the like in addition to the connection terminals. Since the current design of electronic devices in the industry is based on "light, thin and short", in the process of assembling many components, the fixing method is often not strong enough to affect the assembly speed, and between components. If the fixing method is not strong enough, it will affect the quality of the signal transmission of the signal connector. Therefore, this specification and condition of the USB 3.1 connector will create new difficulties and challenges for the production and assembly process.

Therefore, how to design a new assembly structure for the special structural requirements of the USB 3.1 connector enables the manufacturer to quickly produce and quickly and securely assemble while taking into account both "product yield" and "production cost". The USB 3.1 connector has become an important topic for this creation.

In view of the fact that the USB 3.1 connector has many metal parts (ie, connection terminals, metal plates, grounding pieces, etc.), it is difficult for the manufacturer to balance the production cost and yield in production, and the assembly of many metal parts is required. With problems such as difficulty in assembly and firmness, the creator, after years of practical experience and continuous research and testing, finally designed a signal connector that uses trapezoidal block assembly to improve the design.
