The alternating current charging connector includes an alternating current socket and an alternating current plug, wherein the alternating current socket is movably connected with the alternating current plug through a bayonet connection device, the alternating current socket comprises a socket shell body, and the alternating current plug comprises a plug shell body. The alternating current charging connector is characterized in that the socket shell body is provided with an electromagnetic self-locking mechanism which comprises a double-holding electromagnetic lock, an electromagnetic lock pin, an electromagnetic lock push rod and an electromagnetic lock fixing bracket, wherein the electromagnetic lock fixing bracket is arranged on the socket shell body, the electromagnetic lock is arranged on the electromagnetic lock fixing bracket, and the electromagnetic lock push rod is arranged on the electromagnetic lock through the electromagnetic lock pin; the socket shell body is provided with a through hole which allows the electromagnetic lock push rod to pass through; and the plug shell body is provided with a blocking position which is matched with the electromagnetic lock push rod. With the self-locking mechanism, the alternating current charging connector is advantageous in improved safety and reliability, no heating, and long service life.
Description
Technical field
The utility model relates to a kind of electric automobile power supply unit end AC charging connector with self-locking mechanism, specifically a kind of more safe and reliable, without the heating, long service life the electric automobile power supply unit end AC charging connector with self-locking mechanism.
Background technology
Electric automobile is released the electric household automobile one after another because the characteristics such as energy sources is extensive, the peace and quiet of travelling, non-pollution discharge more and more are subject to the attention of each auto vendor.As the charge connector of using to charging electric vehicle, be provided with vehicle-side connector and mains side connector, wherein, vehicle-side connector carries on the electrical storage device on the car body, and is fixed on the car body, and the mains side connector is connected on the power supply of power consumption power.Under the state that the mains side connector is entrenched in vehicle-side connector, charge, charge and again the mains side connector is unloaded down from vehicle-side connector after complete.The AC charging connector if warm swap occurs, will bring great potential safety hazard because the logical electric current that carries is larger, and voltage is higher.Existing product has been only by having designed safety protective circuit at charging device and electric automobile, preventing the generation of warm swap, and can't accomplish 100% safety.
Summary of the invention
The purpose of this utility model provide a kind of more safe and reliable, without the heating, long service life electric automobile power supply unit end AC charging connector.
The purpose of this utility model is achieved through the following technical solutions.
A kind of electric automobile power supply unit end AC charging connector, comprise AC socket and ac plug, be flexibly connected by bayonet mount between AC socket and the ac plug, AC socket comprises Socket casing, ac plug comprises plug casing, it is characterized in that: electromagnetic self-locking mechanism is installed on the described Socket casing, electromagnetic self-locking mechanism comprises two freeze mode electromagnetic locks, the electromagnetic lock pin, electromagnetic lock push rod and electromagnetic lock fixed support, the electromagnetic lock fixed support is installed on the Socket casing, electromagnetic lock is installed on the electromagnetic lock fixed support, and the electromagnetic lock push rod is installed on the electromagnetic lock by the electromagnetic lock pin; Described Socket casing is provided with the through hole that passes for push rod.
The utility model compared with prior art has the following advantages:
The utility model is by having installed electromagnetic self-locking mechanism at AC charging connector body end; and conducting and disconnection by control circuit; direction by electromagnetic lock electric current (voltage) is changed; thereby control electromagnetic lock push rod keeps stretching out or reset mode; reach the purpose of mechanical self-latching; designed safety protective circuit on the charging device of cooperation own and the electric automobile, for product provides second protection, made product more safe and reliable.The utility model adopts two freeze mode electromagnetic locks and by the work of control circuit control electromagnetic lock, makes product reach effect short without heating, reaction time, the high life.
