Abstract: The invention provides a latch and a connector. The latch includes a handle and two baffles. The baffles are disposed on opposite ends of the handle, and opposite to each other. Each baffle includes a main body and a metal sheet. A front end portion of the main body is recessed with pivoting and locking portions, the main body has first and second openings, the first opening communicates with an inner side surface of the pivoting portion, and the second opening communicates with an inner side surface of the locking portion. The metal sheet is disposed in the main body and has an anti-wear portion exposed through the second opening. Latching columns of a connector assembly are latched into the locking portion through the anti-wear portion, such that it prevents the latching columns from directly rubbing against the main body, thereby effectively prolonging the service life of the latch.

Abstract: The present disclosure discloses a touch key design method based on a touch screen, wherein a plastic part is placed on a touch screen, so that the touch screen is equally divided into a plurality of (such as 4×4) areas with the same size. In this way, the touch screen can be regarded as a plurality of (such as 4×4) matrix touch keys. When one of the touch keys is touched by hand, an MCU (a main control unit of a recording software controller) determines which touch key is pressed through the X and Y coordinate values returned by the touch screen, and then controls the corresponding functions. On the touch screen, not only the function name of the recording software corresponding to each touch key is displayed, but also the state of pressing or releasing the touch key and the state about whether the corresponding function on the recording software is activated or non-activated can be displayed in real time.
