Description

Connectors with terminal groups with specific spacing

This invention relates to connectors, and in particular refers to a connector with multiple terminal groups in the same plug slot, and the separation distance between the terminal groups is not less than 4.13 millimeters (mm).

Press, a connector is an electronic device used to connect two or more electronic devices together to realize the transmission of power and signals. Therefore, connectors have been widely used in various industrial fields, such as: communications , information technology, automobiles, consumer electronics, etc. Generally speaking, female connectors and male connectors are two main components. Female connectors (or socket connectors) usually have one or more female slots to accommodate corresponding male connectors. terminal connector, and each slot is usually provided with one or more sets of metal terminals for transmitting electrical signals. In addition, the male connector (or plug connector) is usually equipped with one or more convex tongue plates for insertion into the slot of the female connector, and the shape and size of the tongue plates need to match the slot. Matching the shape and size can ensure that the male connector and the female connector can be connected correctly to transmit electrical signals normally.

However, in some cases, when the receptacle connector needs to meet different transmission purposes (such as transmitting signals or power), terminal groups of different specifications will be provided inside the receptacle connector. In the aforementioned cases, if different specifications When the terminal groups are too close, electromagnetic interference (EMI) may be generated, which will lead to a reduction in the quality of signal transmission. Therefore, manufacturers often set up separation walls between different terminal groups to reduce the aforementioned problems. For this reason, the tongue plate of the male connector needs to have one or more grooves, so that when the male connector and the female connector are plugged in, the dividing wall can smoothly enter the groove to ensure The male connector and the female connector can be plugged in correctly. However, the aforementioned design also limits the compatibility between the male connector and the female connector. In other words, when the tongue plate of the male connector does not have a corresponding groove, it will not be able to mate with the female connector. Correct plugging may cause plugging failure.

In addition, in recent years, there has been an increasing demand for thinner and lighter electronic devices. As the size of the connector shrinks, the strength of its components may decrease. Therefore, when the user plugs the groove-less tongue plate into the female connector When using too much force, the tongue plate or partition wall may be broken and damaged. The broken fragments may fall into the female connector, causing subsequent undesirable problems, such as failure to successfully plug in (obstructed by fragments), Signal transmission is unstable, electrical performance is degraded, maintenance costs are increased, user experience is degraded, etc. Therefore, how to effectively solve the aforementioned problems is a major topic discussed in this creation.

In order to stand out in the fiercely competitive market, the creators rely on their rich practical experience in the design, processing and manufacturing of various power or signal connectors for many years, and adhere to the research spirit of excellence.
