Description

Self-locking plug and endoscope system with same Technical Field The present utility model relates to a medical apparatus, and more particularly, to a self-locking plug and an endoscope system having the same. Background At present, in order to facilitate free insertion and extraction between an endoscope and external equipment comprising a light source device and an image processor, an external cable with a plug is led out from a circuit board of the endoscope so as to be matched with a socket in the external equipment by means of the plug on the external cable, thereby realizing the purpose of free insertion and extraction between the endoscope and the external equipment. However, in the existing plug of the external cable, the button of the plug cannot provide a self-locking function for the hook. Accordingly, there is a need for a self-locking plug and an endoscope system having the same that overcomes the above-mentioned drawbacks. Disclosure of utility model An object of the present utility model is to provide a self-locking plug in which the operation member is used to self-lock the hook.
