  • Patent number: 10418735
    Abstract: A micro-electro-mechanical systems (MEMS) terminal structure of board-to-board electrical connector and manufacturing method thereof are provided. The terminal of the terminal structure includes a side arm, a bent portion, and a flexible arm integrally formed as one component. The flexible arm includes a first portion and a second portion. The first portion and the side arm form an insertion space. The second portion and the side arm form a locking space. The second portion of the flexible arm has a contact portion. The insertion space is greater than the locking space. The terminal has curved and locking features to extend the moment arm of the terminal for improving the terminal flexibility. The terminal contacts a mating terminal through multiple points, thereby improving the contact stability and providing the locking function. Furthermore, by using the MEMS techniques for semiconductor industries, the terminal of micro board-to-board electrical connector can be manufactured.

  • Patent number: 10069224
    Abstract: An electrical plug connector includes a plug insulated housing which is integrally formed and plug terminals. A transition segment connected between first and second contact portions of each plug terminal allows the first contact portion to be in contact with and arranged substantially parallel to the second contact portion, so that connectors with reduced width can be manufactured. In addition, the shaping space between a first recessed portion and a second recessed portion of each plug terminal receive materials for forming the plug insulated housing, thus improving the structural strength of the connector. Moreover, embedded ends allow the plug terminals to be secured with the plug bottom wall, so that the plug terminals would not detach from the plug insulated housing easily during manufacturing or operation. The structural strength of the electrical plug connector can be improved, and the plug terminals can be properly assembled with the plug insulated housing.
