Description

Signal connector for locating the spacer using an assembled tongue

The present invention relates to a signal connector for locating a partition plate by using an assembled tongue plate, in particular, a tongue plate is designed to be composed of a first seat body and a second seat body embedded with each other for assembling and positioning a space plate signal. Connector.

Button, the connector refers to all connected components and their accessories on the electronic signal and power supply. It is a bridge for all signals. Its quality will affect the reliability of current and signal transmission, and also with electronics. System operation is closely related. With the increasing development of electronic technology, signal connectors have become an indispensable component of various electronic devices for data transmission and connection with other peripheral devices. Among the transmission specifications of many connectors, the Universal Serial Bus (USB) is the most popular, because the USB specification connector can provide hot plug and plug-and-play (Plug- n-Play) allows users to connect various USB devices (such as mouse, keyboard, scanner, digital camera, printer, etc.) via USB connector without rebooting. Since the official launch of USB 1.0 in 1996, USB connectors have become one of the main specifications for interconnecting various electronic devices.

At present, the USB specification is about to fully enter USB 3.1. USB3.1 not only improves the transmission of voltage and current, but also improves the transmission loss to 10GB per second due to improved coding loss. In addition, compared to the past USB1.0~USB 3.0 specification, the connector structure of Type-C in USB 3.1 has a major change, that is, "the configuration is symmetrical up and down", so Users will not need to specifically identify the front and back of the USB3.1 plug, but can be arbitrarily inserted into the corresponding USB 3.1 socket, making the use more intuitive. 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. In the current industry, the "light, thin and short" is the mainstream design electronic device, the USB 3.1 connector This specification will create new difficulties and challenges in the production and assembly process.

In the past, when designing connectors, the manufacturer fixed the connection terminals to a tongue plate by "injection molding" or "insertion assembly". However, in order to make the connector configuration light enough, the USB 3.1 connector The two sets of signal terminals in the middle must be designed to be very close to save the volume. In addition, in order to avoid the mutual interference of the signals of the two sets of connecting terminals during transmission, the operator must still be between the two sets of connecting terminals. Try to install a metal partition plate to block each other's signal and noise interference. All of the above conditions will seriously affect the cost and yield of the manufacturer when producing USB 3.1 connectors. If the "injection molding" process is used and the spacers and the two sets of connection terminals are fixed in the tongue plate at the same time, the quality requirements for injection molding will be extremely high, and the production cost will be increased in tandem; otherwise, if the assembly is "inserted" In the manner of assembling the partition plate and the connecting terminal, it is difficult for the operator to accurately control the production process because the structure of the connector is minute and difficult to be inserted.

Therefore, how to design a new assembly structure for the special structural requirements of the USB 3.1 connector, enabling the manufacturer to quickly manufacture and assemble USB 3.1 connectors while achieving both "product yield" and "production cost". This is an important topic that this creation is intended to solve here.

In view of the fact that the USB 3.1 connector has more metal parts (ie, the connection end) Sub-, spacer, etc.), which makes it difficult for the industry to balance production costs and yields. The creator, after years of practical experience and after continuous research and testing, finally designed a use assembly of this creation. The signal connector of the tongue positioning spacer can improve many of the aforementioned problems.

One of the purposes of this creation is to provide a signal connector that utilizes an assembled tongue to position a spacer that conforms to the USB 3.1 specification and includes an assembled tongue, two grounding lugs, a spacer, and a metal shell. The assembled tongue includes a first seat body and a second seat body, wherein the first seat body is fixed with a plurality of first connecting terminals, and one of the first connecting terminals is exposed One side of the first body is formed to form a plurality of first contacts, and a first assembly groove is recessed on one side of the first body, and the other side of the first body is adjacent to the two corresponding ends Each of the second connecting terminals is provided with a plurality of second connecting terminals, and one of the second connecting terminals is exposed on one side of the second base. Forming a plurality of second contacts, wherein the second contacts correspond to the first contacts, and a second assembly slot is recessed on one side of the second base, and the second base is another a second embedding portion is respectively disposed at a position on one side adjacent to the two corresponding ends, and the second embedding portion is respectively And extending from the other side of the second body, and can be respectively inserted into each of the first engaging portions, so that the first seat and the second seat can be combined into the assembled tongue. And a positioning groove can be formed between the other side of the first body and the second body; each of the grounding plates is matched with each of the assembly grooves to be positioned in each of the assembly grooves; The spacer is a sheet made of metal, and the configuration is matched with the positioning groove so that the spacer can be assembled and fixed into the positioning groove (for example, by inserting one end of the assembled tongue to In the positioning groove, or when the first seat body and the second seat body are combined into the assembled tongue plate, the partition plate is assembled and fixed to the positioning groove, so that the partition plate can be located at the connecting terminals. Preventing signals on the first connection terminal and the second connection terminal from interfering with each other; the configuration of the metal case is matched with the assembled tongue plate to be assembled to the grounding piece and the spacer plate respectively After the assembled tongue, the assembled tongue can be assembled into the metal housing. In this way, the assembly relationship between the first base body and the second base body can provide a more convenient assembly manner, so that the assembler can quickly and stably position the partition plate between the connection terminals. To improve the production efficiency of the signal connector.

Another purpose of the present invention is that each of the first embedded portions is a first bump and a first recess, and each of the second latch portions is a second recess and a second bump. And the position of the second groove corresponds to the first protrusion, and the configuration is the same as the first groove; the position of the second protrusion corresponds to the first groove, and the structure The type is the same as the first protrusion; that is, the configuration of the first seat is the same as the second seat, whereby the first seat and the second seat can be produced by the same mold. Therefore, it can greatly improve production costs.
