Abstract
Description
Technical Field
[0001] The present invention relates to a connector terminal, a connector including the connector terminal, and a connector assembly including the connector. Background Technology
[0002] In existing technologies, connectors typically include a housing and multiple sheet-like terminals disposed within the housing. Each terminal has a pin for insertion into a socket on a circuit board. This results in an excessive number of sockets on the circuit board, reducing the current-carrying capacity per unit area, i.e., reducing the current density of the circuit board. Therefore, in existing technologies, when it is necessary to increase the current-carrying capacity of the connector, the area of the circuit board must be increased. However, in some space-constrained applications, the area of the circuit board cannot be increased, which makes it difficult for existing connectors to be used in these space-limited applications, severely restricting the application range of the connectors.
