Description

Technical Field

[0001] The utility model relates to the technical field of electrical components, and more specifically, to a low-height connector. Background Art

[0002] Electrical connectors are electro-thermo-mechanical devices that allow for detachable connections to transmit power and electrical signals. Signals or electrical power are transmitted through metal conductors, and plastic housings are used in connectors to isolate the metal conductors from each other. The plastic housing is also used to align the conductors and ensure that the conductors are securely locked to the insulator. For interconnect solutions on circuit boards, typical on-board connectors, whether male or female, are assembled on the circuit board.

[0003] In the pursuit of miniaturization, various components are trying to reduce their height as much as possible. This trend of reducing height also occurs in the design of electrical connectors. However, although electrical connectors are used in circuits and need to meet the electrical requirements in the specifications, they also need to meet the standards for mechanical properties listed in the specifications in mechanical applications. These two factors make electrical connectors inherently limited in miniaturization. In electrical transmission, in order to achieve the required current, the spacing and size of the conductors must be kept at a certain size. Less than this size will increase resistance, thereby increasing force and temperature, thereby limiting the current. In terms of mechanical properties, electrical connectors need to be able to withstand the insertion and removal force and retention force in the application, as well as various requirements for structural performance. Electrical connectors that are too thin and too fine will not be able to meet the mechanical requirements of the specifications in terms of mechanical performance. The height of the electrical connector becomes the determining factor of the height of the entire circuit system.

[0004] Therefore, after the miniaturization of electrical connectors has reached a bottleneck, it is necessary to find a breakthrough in connectors and circuit boards. Utility Model Content
