DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0032] like Figure 1-Figure 5 As shown, a charging gun connector proposed in one embodiment of the present application includes:

[0033] The gun body 1 has a charging end 101 at one end and a connection end 102 at the other end. The charging end 101 of the gun body 1 is used to connect to an electric vehicle, while the connection end 102 is used to connect to a charging pile.

[0034] The double-port connector 2 is provided at the connection end 102 of the gun body 1 and has a spacer 201 in the middle. The double-port connector 2 is mainly used to connect to the charging pile, and the spacer 201 is provided between the two interfaces.

[0035] The socket terminal block 3 is connected to the charging pile and has a socket 301 at its end for socketing with the double-port connector 2. One end of the socket terminal block 3 is connected to the charging pile, and the socket 301 is configured at the other end;

[0036] The clamping member 4 is configured with two horizontal sliding grooves 401 arranged opposite to each other in the sleeve end block 3. A clamping block 402 is slidably installed in the horizontal sliding groove 401. A through groove 403 for the clamping block 402 to be inserted into is configured on the partition plate 201. Under normal circumstances, the clamping block 402 is located inside the horizontal sliding groove 401 and is not inserted into the through groove 403.

[0037] The trigger member 5 includes a transmission member 501 installed in the sleeve end block 3 and used to push the clamping block 402 to move horizontally. The upper end of the transmission member 501 movably penetrates the sleeve end block 3. A pressing plate 502 is hinged on the top of the gun body 1. One end of the pressing plate 502 is configured with a trigger block 503 for driving the transmission member 501. The pressing plate 502 is connected to a water retaining sheet 504 for wrapping the trigger block 503.

[0038] When the gun body 1 and the sleeve end block 3 are connected together, the clamping block 402 is inserted into the through groove 403. At this time, the clamping block 402 limits the gun body 1 horizontally, and the insertion groove 301 of the sleeve end block 3 limits the gun body 1 vertically, thereby realizing the connection. Moreover, the connection structure is located inside the sleeve end block 3 and the double-port joint 2, which can effectively improve the stability of the connection, reduce contact with the outside world, avoid rain erosion, and increase service life.

[0039] When the gun body 1 is detached from the socket end block 3 and replaced, it is necessary to first insert the double-port connector 2 into the socket slot 301 of the socket end block 3, and then use the pressing plate 502 to drive the trigger block 503 to drive the transmission part 501 to operate, so that the two clamping blocks 402 move relative to each other, so that the clamping blocks 402 enter the through groove 403 to achieve clamping connection. At the same time, the water baffle 504 on the pressing plate 502 will wrap the connection between the trigger block 503 and the transmission part 501, so as to reduce contact with the external environment, increase safety and improve service life.

[0040] like Figure 4 and Figure 6 As shown, in some embodiments, the two horizontal sliding grooves 401 are arranged relative to each other and staggered, and the clamping block 402 includes a slider 4021 slidably installed in the horizontal sliding groove 401, and a reset spring 4022 is connected between one end of the slider 4021 and the inner end of the horizontal sliding groove 401. The width of the through groove 403 is equal to the sum of the widths of the two horizontal sliding grooves 401. It should be noted that the transmission member 501 can only drive the two sliders 4021 to move relative to each other in the horizontal sliding groove 401. The trigger block 503 is used to drive the transmission member 501 and also to limit the transmission member 501. When the trigger block 503 disengages from the transmission member 501, the slider 4021 loses its limit, and the reset spring 4022 can automatically pull the slider 4021 out of the through groove 403.

[0041] like Figure 6 As shown, in some embodiments, the opposite ends of the two sliders 4021 are constructed with chamfers, and the width of the through groove 403 is equal to the width of the two sliders 4021. Therefore, the two sliders 4021 can effectively resist the limiting sleeve end block 3 and the double-port joint 2 after entering the through groove 403, and setting chamfers at the ends of the sliders 4021 can make it easier to insert them into the through groove 403, avoid them from getting stuck, and increase safety.

[0042] like Figure 6As shown, in some embodiments, the slider 4021 is constructed with a vertical block 40211 arranged near the return spring 4022, and the vertical block 40211 is constructed with a vertical groove 40212. The sleeve end block 3 is constructed with two movable grooves 302 arranged opposite and staggered. The transmission member 501 includes a pushing lever 5011, the middle part of the pushing lever 5011 is hinged in the movable groove 302, and the lower end of the pushing lever 5011 is constructed with a horizontal axis 5012 movably installed in the vertical groove 40212. The sleeve end block 3 is constructed with an inclined sliding groove 303 connected to the movable groove 302 and passing through the top side of the sleeve end block 3. A guide block 5013 is slidably installed in the inclined sliding groove 303. The bottom of the guide block 5013 is constructed with an arc-shaped connecting rod 5014 movably set in the movable groove 302 and hinged to the other end of the pushing lever 5011. The trigger block 503 is used to push the two guide blocks 5013 to move away from each other. It should be noted that the pushing lever 5011 is initially tilted downward and is arranged in a "V" shape with the inclined sliding groove 303. When the trigger block 503 pushes the two guide blocks 5013 to move away from each other, the guide block 5013 will move in the direction of the inclined sliding groove 303, thereby driving one end of the pushing lever 5011 to flip around its midpoint, thereby causing the other end of the pushing lever 5011 to move up and down in the vertical groove 40212 while driving the vertical block 40211 to move toward the through groove 403, thereby realizing the horizontal movement of the slider 4021. Setting the transmission structure inside the socket end block 3 can effectively reduce contact with the outside world, ensure the smooth operation of the structure, and increase the service life of the mechanical structure.

[0043] like Figure 4 and Figure 6As shown, in some embodiments, the opposite ends of the two guide blocks 5013 are constructed with beveled surfaces 50131, and the trigger block 503 includes a connecting column 5031 fixedly connected to the bottom side of one end of the pressing plate 502. The bottom of the connecting column 5031 is hinged with two triangular blocks 5032 arranged oppositely and used to wrap the connecting column 5031. The inclined surfaces of the triangular blocks 5032 fit with the beveled surfaces 50131. A placement groove 50132 for clamping the two triangular blocks 5032 is constructed between the lower sides of the two guide blocks 5013. The width of the placement groove 50132 is less than the sum of the widths of the two triangular blocks 5032. When the trigger block 503 is driven by the pressing plate 502 to move downward, it will first abut against the two beveled surfaces 50131, and then push the two guide blocks 5013 in opposite directions through the misaligned abutment of the inclined surfaces until the two triangular blocks 5032 enter the beveled When the slider 4021 is inserted into the through-groove 403, it is only necessary to move the trigger block 503 upward so that the connecting column 5031 drives the triangular block 5032 to move upward. At this time, the triangular block 5032 is resisted by the upper side of the placement groove 50132 and flipped toward both sides until it flips to the lower side of its hinge point. The guide block 5013 can be slid out of the placement groove 50132 by using the inclined surface. The engaging and disengaging operations only require the trigger block 503 to move up and down, which increases convenience.

[0044] like Figure 5-Figure 8 As shown, in some embodiments, the pressing plate 502 includes a step plate 5021, the middle part of the step plate 5021 is hinged to the gun body 1 through a hinge shaft 5022, and a torsion spring 5023 is connected between the hinge shaft 5022 and the gun body 1, and the trigger block 503 is connected to the lower side of one end of the step plate 5021. It should be noted that the pressing plate 502 is a lever structure, one end is a pressing end, and the other end is a movable end. When the trigger block 503 needs to enter between the two guide blocks 5013, it is only necessary to press the movable end downward to insert the slider 4021 into the through groove 403, and pressing the pressing end can make the slider 4021 detach from the through groove 403, which is convenient to operate. The torsion spring 5023 is mainly used to ensure that the movable end always has a tendency to move downward, thereby ensuring that the trigger block 503 can be stably placed in the placement groove 50132, thereby increasing safety.

[0045] like Figure 2As shown, in some embodiments, a rubber buffer block 6 is connected to the gun body 1 and is located below the other end of the step plate 5021. When the trigger block 503 is placed in the groove 50132, the two triangular blocks 5032 require a certain force to flip over, so as to disengage from the guide block 5013. Therefore, the pressing end of the pressing plate 502 requires a certain pressing pressure. Repeated pressing during long-term use will cause the end of the pressing plate 502 to collide too much with the gun body 1 and break. Therefore, the provision of the rubber buffer block 6 can buffer the impact force, increase safety and service life.

[0046] like Figure 4-Figure 5 As shown, in some embodiments, the water retaining plate 504 is connected to the edge of the step plate 5021 in a ring shape and wrapped around the trigger block 503. The upper side of the sleeve end block 3 is constructed with a water-isolating ring block 304 for wrapping the top opening of the inclined sliding groove 303. The water-isolating ring block 304 is located on the inner side of the water retaining plate 504. The water-isolating ring block 304 and the water retaining plate 504 are both made of flexible rubber material and can be wrapped around each other to wrap the opening and the trigger block 503, reducing contact with the outside world and increasing safety.

[0047] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
