Description

Signal connector socket with equidistant signal terminal and grounding terminal

Technical Field

The present invention relates to a connector, and more particularly to a signal connector socket having equidistant signal terminals and ground terminals, which can stably and rapidly transmit signals in a state of being less susceptible to electromagnetic interference.

Background

The signal Connector (Connector) generally refers to all the connecting elements and accessories thereof applied to electronic signals and power supplies, and is a bridge for all signals, and the quality of the signal Connector affects the reliability of current and signal transmission and is related to the operation of the electronic device. Generally, various types of connectors are installed on various electronic devices (e.g., smart phones, tablet computers, desktop computers, notebook computers, digital cameras, etc.) to enable the electronic devices to exchange information with each other, so that the connectors can electrically connect and transmit signals between the devices, the components, and the systems to form a basic component required by a complete system.

As a result of research, in the last decade, the connector industry has been a profitable industry for many taiwan manufacturers entering the connector industry, compared with other component industries, and the main reason is that the technical differences used in the high-low level connector products in the connector industry are very large, and the aforementioned characteristics make the positioning of the related products between the international factories and taiwan manufacturers very clear and definite, and in addition, because each international factory also needs to have a wide application capability for the various connector products manufactured by entrustment, this strict product requirement also forces the taiwan manufacturers who accept the entrustment to have different special attacks, thereby avoiding the subsequent red sea (related china manufacturers) competition.

However, as early as ten years since the financial storm in 2008, taiwan manufacturers related to connectors have experienced and experienced an industrial crisis, and therefore, many taiwan manufacturers clearly recognize that they rely on the PC industry only, and are easily confronted with the dilemma of the PC industry being unstable, entering threshold being too low, and industry competition being fierce, which results in a survival crisis that the operators cannot continue to operate. Therefore, many taiwan manufacturers have made some corresponding adjustments on the operation strategy, and hope to utilize the multi-transformation strategy to cover the application level of the connector product to the communication or consumer electronic products, such as: therefore, taiwan manufacturers, who originally rely on a large number of connectors for computers and peripheral devices, have been turning to the "litz connectors" for developing and producing various consumer electronic products, displays, etc. in recent years.

However, as mentioned above, the financial storm in 2008 has broken through the industry implication that many practitioners have been following for a long time in taiwan connector industry, for example, the manufacturers in the united states, europe and japan originally producing high-level or high-end technology connectors are forced to be in shortage of profit, considering that the manufacturers start to produce low-level or low-level connectors and seriously invade the dominant product line mastered by taiwan connector manufacturers for many years, in the face of this severe change, taiwan connector manufacturers must accelerate the step adjustment, add new strategies to the points and faces that have not been discussed in the past, and conduct research, development and improvement on various characteristics of connectors to provide better connector products in the industry, so that the manufacturers can occupy a lot in the market.

Now, only a conventional signal connector is taken as an example, and the following description is given. Generally, signal connectors are used as an important bridge for signal exchange and communication between different electronic devices, and therefore, with the development of information industry, the requirements of the general public on the quality and Speed of signal transmission between electronic devices are increasing, and various signal connectors on the market gradually develop from the early USB 1.0 specification to the USB 2.0 specification, and have now further developed to the USB 3.0(Super Speed USB) specification and the USB3.1 Gen 2 specification; among them, the maximum transmission Speed of the early USB 1.0 specification is 12Mbps, the maximum transmission Speed of the USB 2.0 specification is only 480Mbps, however, in the signal connector generation of the USB 3.0(Super Speed USB), the maximum transmission Speed has been increased to 5Gbps, even more, in the signal connector generation of the USB3.1 Gen 2 specification, the transmission Speed is increased to 10Gbps at a time, so as to meet the urgent need of high-Speed signal transmission and exchange between electronic devices, in view of this, the signal connector industry has developed various high-frequency signal connectors for transmitting signals at high Speed, and in addition, in order to ensure that the high-frequency signal connectors can not be interfered by electromagnetic waves around when transmitting high-frequency signals at high Speed, the signal connector industry has developed various high-frequency signal connectors for anti-electromagnetic interference to the greatest extent, and the high-frequency signal connectors have been developed in "light, thin" state, Under the strict market requirement of short and small, in order to take into account the functions and characteristics of high-speed signal transmission and electromagnetic wave interference resistance, the structure of each high-frequency signal connector is not only increasingly complex, but also the manufacturing process is increasingly complicated, so that the manufacturing cost and the reject ratio are always high. Therefore, how to develop a signal connector socket, which not only has a simple structure design and can greatly simplify the manufacturing process, thereby effectively reducing the product reject ratio and the manufacturing cost, but also can enable the signal connector socket to stably and rapidly transmit signals under the state of not being easily subjected to electromagnetic interference, becomes an important issue for various current large connector design and manufacturing manufacturers to find improvements urgently, and is also an important issue to be discussed and solved in the following.
