[0030] Specific Embodiment 1: A charging quick-connect connector with locking function, characterized in that it includes a plug 1, a socket 2 and a locking device 3.

[0031] like Figure 2 , 3 As shown, the left end of the plug 1 has a cylindrical protrusion extending outward from the inside, serving as the charging insertion end 101, and the right end of the socket 2 has a cylindrical recess, serving as the charging matching end 201. The recess of the charging matching end 201 matches the charging insertion end 101, and the two are movably connected.

[0032] The charging insertion end 101 has a number of charging terminals inside, and the charging matching end 201 has a charging socket corresponding to each of the charging terminals inside. When the charging insertion end 101 is connected to the charging matching end 201, the charging terminals contact and are electrically connected to the charging socket.

[0033] The locking device 3 includes a hook 301 and a locking seat 302.

[0034] like Figure 2 , 4As shown, the hook 301 is fixedly arranged at the upper central part of the plug 1, and is horizontally protruded to the left as a columnar protrusion. The head end of the left side of the hook 301 is protruded upward to form a hook end for clamping.

[0035] As shown, Figure 3 the locking seat 302 is fixedly arranged at the upper central part of the socket 2. The lower part of the locking seat 302 is horizontally provided with a locking cavity 3021. The locking cavity 3021 corresponds to the spatial position of the hook 301 when the hook 301 is installed. When the plug 1 is inserted into the socket 2, the hook 301 is embedded in the locking cavity 3021. Figure 7

[0036] As shown, Figure 5 , 6 the locking seat 302 is vertically protruded upward above the locking cavity 3021. The protrusion is centrally provided with a cylindrical sliding groove vertically communicating with the locking cavity 3021. A cylindrical lock 3022 is slidingly embedded in the sliding groove. Two vertical slots are provided on both sides of the protrusion embedding the lock 3022, and the lock 3022 is provided with a horizontal protruding sliding groove 3023. The lock 3022 and the sliding groove 3023 are slidingly moved along the slots within a limited distance. When the plug 1 is inserted into the socket 2, the sliding groove 3023 is clamped at the lowermost end of the slot, and the lower end of the lock 3022 is lower than the hook end of the protruding hook 301. When the sliding groove 3023 is clamped at the uppermost end of the slot, the lower end of the lock 3022 is higher than the hook end of the protruding hook 301.

[0037] As shown, Figure 2 , 8 the unlocking lever 102 is arranged above the hook 301. The unlocking lever 102 is composed of two parallel rods with rod ends flush. The two rods are fixedly connected by a plate at the end away from the hook 301. The two rods of the unlocking lever 102 are arranged in the direction of the protruding hook 301. The middle parts of the two rods are hingedly connected to the plug 1, and can be freely rotated around the hinge points. When the plug 1 is inserted into the socket 2, the rod ends of the two rods of the unlocking lever 102 close to the hook 301 are respectively extended below the protruding sliding grooves 3023 of the two ends of the lock 3022. The connecting plate at the end of the unlocking lever 102 away from the hook 301 is provided with a flat lower pressing button.

[0038] ​Installation and locking: Press down the push button, and the end of the unlocking torsion bar 102 located below the lever 3023 will rotate upward around the hinge point. During the rotation, the end of the lever lifts the lever 3023 above and drives the latch 3022 to move upward together. When the lever 3023 presses against the uppermost end of the slot, the cylindrical lower end of the latch 3022 is higher than the protruding hook end of the hook 301. The hook end of the hook 301 is not obstructed and extends into the locking cavity 3021 during insertion. Release the push button, and the latch 3022 slides down under the action of gravity. When the plug 1 and the socket 2 are inserted into place, the latch 3022 falls down and engages with the hook end of the hook 301 to lock, realizing the locking connection between the plug 1 and the socket 2.

[0039] Quick unlock: Press down the push button, and the end of the unlocking torsion lever 102 located below the lever 3023 will rotate upward around the hinge point. During the rotation, the end of the lever lifts the lever 3023 above and drives the latch 3022 to move upward together. When the lever 3023 presses against the uppermost end of the slot, the cylindrical lower end of the latch 3022 is higher than the protruding hook end of the hook 301. The hook 301 and the latch 3022 are no longer locked, and the plug 1 and the socket can be pulled apart.

[0040] Specific Implementation Example 2: As shown in the example Figure 4 , 6 As shown, the upper part of the hook end of the hook 301 faces the socket 2 and is inclined at an angle, while the lower end of the latch 3022 faces the plug 1 and is also inclined at an angle. During the above installation and locking process, it is no longer necessary to press the down button to lift the latch 3022 to allow the hook 301 to enter the space. When the hook 301 is inserted inward, the latch 3022 can be automatically lifted by the inclined surface.

[0041] Specific embodiment three: Based on the above specific embodiments, a handle-shaped grip 4 is added to the rear of the plug 1. The grip 4 is adjacent to the pressing button of the unlocking torsion bar 102. When the user holds the plug 1 with one hand through the grip 4, the thumb of the holding hand is directly facing the pressing button, and the above-mentioned quick unlocking process can be easily performed with one hand.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the invention. All variations, modifications and substitutions within the spirit and principle of the present invention are within the protection scope of the present utility model.
