Abstract
The utility model provides a device for attachment plugs, cable couplers, equipment couplers, and the like, which are used in electric tools and machines that are particularly adapted for indoor and outdoor usage. The utility model of electric connector comprises a guide location groove, a rotary rebound adaptor for a metal contact spring A, and a rotary rebound joint seat whose pore wall is provided with a guide location lug boss and a metal contact spring B. The electric connection is achieved by the engagement between the metal contact spring A and the metal contact spring B. The utility model can be widely used, ensure safety, and prevent accidental electrical shock (The conductive elements can not be touched even though a conductive body is put into an open hole. No conductive body is exposed after or when the connector is connected, thereby effectively increasing the assurance coefficient and preventing the occurrence of accidental electric shock). The utility model can greatly reduce the striking of arc; material is easy to get; the process is simple; the brass product can be saved greatly; the costs is low and standardization can be achieved. Besides, the utility model has the advantages of appropriate structure, simple operation, and reliable connectivity. In particular when the power supply is turned on, the connector has the function of self-locking, therefore the electric connecting is good because such external force as vibration and collision can be prevented (Here, because the connecting elements are engaged and fastened with each other, and are powered on, the abilities of vibration resisting, collision resisting, drop resistance are fine. Only hand correct manual operation can pull them out).
Description
Technical field
The utility model relates to a kind of electric tool and utensil novel electric connector, and this connector mainly is applicable to the electric tool of indoor and outdoor use and plugs and sockets and cable coupler, utensil coupler etc. that utensil is used.
Background technology
