[Prior Art] Nowadays, with the trend of miniaturization of various electronic products, the corresponding electrical connectors also need to be correspondingly miniaturized, so that the miniature electrical connectors are used in various microelectronic products, and the miniature electrical connectors and docking When the connector is docked, the connector is small in size, and the docking connector is unstable. It is easy to disconnect the connector from the docking connector, so that the signal cannot be stably transmitted. Therefore, the micro-electric connector is often provided with a locking member for engaging with the corresponding butt-locking member of the mating connector, so that the electrical connector and the mating connector are stably connected, and the signal is stabilized. However, the lock member is usually held in the electrical connector by the self-setting clip. Since the micro-electric connector is small in size, the lock member assembled therein is also small in size, and the clip is provided on the lock member. Also correspondingly small 'cannot stably hold the locking member in the electrical connector. It is therefore desirable to provide an electrical connector having a stable retention latch. 'New Content' The purpose of this creation is to provide an electrical connector with a stable retention latch. In order to achieve the above object, the present invention provides an electrical connector including a metal case, an insulative housing received in the y metal case, a terminal set housed in the insulating body, and a locking component assembled in the insulating body, wherein The outer surface of the metal casing is provided with a first bent piece and a second bent piece which are bent inwardly.
