Description

Engine harness connector anti-disengaging structure Technical field: The utility model relates to the technical field of wire harness connectors, in particular to an engine wire harness connector anti-disengaging structure. The background technology is as follows: At present, a conventional electronic control diesel engine wire harness connector has a once locking function on a sensor (or an actuator). In some special usage environments, due to the actions of pressing other contact objects, manual misoperation (such as pressing the elastic handle of the connector sheath by accident), as shown in fig. 1, the harness connector 2 is provided with the locking bar 21 and the elastic handle 22, and the locking bar 21 can be moved upwards by pressing the elastic handle 22, so that the limit bump 11 on the sensor 1 can be separated, and the harness connector of the engine can be separated from the sensor (or the actuator) when the harness connector of the engine does not need to be separated.
