Description

Low-height connector

Technical Field

The utility model relates to the technical field of electrical components, in particular to a low-height connector.

Background

An electrical connector is an electro-thermal mechanical device that allows for a detachable connection to transmit electrical power and electrical signals. Signals or electrical power are transmitted through the metal conductors, while plastic housings are used for connectors to isolate the metal conductors from each other. The plastic housing also serves 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, either male or female, are assembled on the circuit board.

In the trend of miniaturization, various components are being reduced in height as much as possible. This trend to reduce height also occurs in the design of electrical connectors, however, although electrical connectors are used in electrical circuits, it is necessary to meet the electrical requirements of the specification, and in mechanical applications, it is also necessary to meet the standards listed in the specification for the relevant electrical performance. Both of these make electrical connectors inherently limited in miniaturization. In electrical transmission, in order to achieve the required amount of current, the spacing of the conductors and the size of the conductors must be maintained at a certain dimension, less than which increases resistance, thereby increasing temperature and thus limiting the amount of current. In terms of mechanical properties, the electrical connector needs to be able to withstand the insertion and removal forces and retention forces applied, and there are various requirements for structural properties, and an electrical connector that is too thin and thin may not meet the mechanical requirements of specifications in terms of mechanical properties, and the height of the electrical connector becomes a determining factor for the height of the entire circuit system.

It is therefore necessary to find breaks in the connector and the circuit board after the miniaturization of the electrical connector has reached a bottleneck.
