Signal connectors for bulkhead positioning using assembled tongues

technical field

The utility model is a signal connector which utilizes an assembled tongue plate to position a spacer plate, especially a tongue plate designed to be composed of a first base body and a second base body embedded in each other for assembling and positioning a spacer plate signal connector.

Background technique

Signal connector (Connector) generally refers to all connection components and accessories used in electronic signals and power supplies. It is a bridge for all signals. Its quality will affect the reliability of current and signal transmission, and it is also related to the operation of electronic systems. closely related. With the increasing development of electronic technology, signal connectors have become an indispensable equipment for various electronic devices in data transmission and connection with other peripheral devices. Among the transmission specifications of many connectors, the Universal Serial Bus (Universal Serial Bus, hereinafter referred to as USB) is the most popular, because the USB specification connector can provide hot plug (Hot Plug) and plug-and-play (Plug-n -Play) allows users to connect various USB devices (such as mice, keyboards, scanners, digital cameras, printers, etc.) After its launch, the USB connector has become one of the main specifications for interconnecting various electronic devices.

At present, the USB specification is about to enter USB 3.1 in an all-round way. USB 3.1 not only increases the transmission capacity of voltage and current, but also can greatly increase the transmission speed to 10GB per second due to the improvement of coding loss. In addition, compared with the past USB1.0~USB 3.0 specifications, the Type-C connector structure in USB 3.1 has a major change, that is, "the configuration is symmetrical up and down", so users will not need to identify USB3. 1, the front and back of the plug can be inserted into the corresponding USB 3.1 socket arbitrarily, making the use more intuitive. However, in order to achieve the pluggable function of both the front and back sides, the USB 3.1 connector must be equipped with two sets of identical connection terminals. This specification condition will bring new difficulties and challenges to the production and assembly process.

In the past, when designing connectors, the industry mostly used "injection molding" or "insert assembly" to fix the connecting terminals into a tongue plate. However, in order to make the connector light enough, the USB 3.1 connector The two sets of signal terminals must be designed very close to save space. In addition, in order to avoid the problem of mutual interference between the signals of the two sets of connection terminals during transmission, the industry must also place between the two sets of connection terminals. Try to install a partition made of metal to block each other's signal and noise interference. All the aforementioned conditions will seriously affect the cost and yield of the industry when producing USB 3.1 connectors. If the "injection molding" process is used to fix the spacer and two sets of connecting terminals in the tongue plate at the same time, the quality requirements for the injection molding will be extremely high, and the production cost will be increased; on the contrary, if the "insert assembly" is used In this way, when assembling the spacer boards and connecting terminals, it is difficult for the industry to accurately control the production process because the structure of the connector is small and precise, and it is not easy to insert and insert.

Therefore, how to design a new assembly structure for the special structural requirements of the USB 3.1 connector, so that the industry can quickly produce and assemble the USB 3.1 connector while taking into account "product yield" and "production cost" , promptly become the important problem that the utility model wants to solve urgently here.
