Description

Technical Field

[0002] In existing flexible circuit boards, if multiple circuit boards are to be installed on the same device, connectors are usually used to connect the terminals of two or more circuit boards, so that it is not easy to be confused when installing the circuit boards later, and the installation is also more convenient. Prior art, such as the Chinese patent application number 202320626781.X and the publication date of 2023.12.15, discloses an electrical connector housing and an electrical connector.

However, during the assembly process, whether the connection terminals are inserted into the connector or the connector is sleeved on the connection terminals, the problem of mutual collision needs to be considered when the connector and the connection terminals are close to each other. If there is no limiting function, it is easy for the connector to touch the connection terminals and cause the circuit board to be misaligned, which makes it difficult to install the connector and the connection terminals, resulting in reduced assembly efficiency.
