DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-5 A replaceable terminal assembly for a liquid-cooled charging gun includes a charging gun body 1, a mounting port 11 is provided on one side of the charging gun body 1, a power connection module 101 is provided in the mounting port 11, the power connection module 101 is connected to a terminal assembly 4 through a plug-in barrel 3, and the terminal assembly 4 includes a main terminal 411 and an auxiliary terminal 421;

[0026] Furthermore, a plurality of main plugs 41 and auxiliary plugs 42 are installed inside the plug-in barrel 3, wherein a main terminal 411 is sleeved and installed inside the main plug 41, a boss 6 is provided on one side of the main terminal 411, and a threaded wall 5 is provided on the other side, and an auxiliary terminal 421 is sleeved and installed inside the auxiliary plug 42;

[0027] Furthermore, special-shaped clamping strips 9 are respectively provided on both sides of the plug-in tube 3, and the special-shaped clamping strips 9 are clamped and installed in the clamping grooves 10 provided on the inner wall of the mounting opening 11 on one side of the charging gun body 1;

[0028] Furthermore, a pressing groove 12 is provided at the bottom of the charging gun body 1, and a pressing plate 8 is flexibly connected in the pressing groove 12. A rubber strip 81 is provided on one side of the pressing plate 8, and a clamping block 82 is provided on the other side. The clamping block 82 is limitedly installed in a limiting groove 13 provided on the inner wall of the mounting port 11.

[0029] Furthermore, a locking shell 2 is sleeved and installed on the outer side of the charging gun body 1 . The locking shell 2 is in compression contact with the outer wall of the charging gun body 1 , and the bottom end of the inner wall is in friction and compression contact with the rubber strip 81 .

[0030] Furthermore, a mounting opening 11 is provided at one end of the charging gun body 1, a power connection module 101 is provided inside the mounting opening 11, and a limiting groove 13 is provided on the bottom wall of the mounting opening 11, a clamping block 82 is slidably installed in the limiting groove 13, and one side of the clamping block 82 is beveled.

[0031] Furthermore, slots are respectively provided on both sides of the plug-in tube 3, and special-shaped clip-on strips 9 are installed in the slots. A protrusion is provided in the middle of the special-shaped clip-on strip 9, and when the plug-in tube 3 is connected to the installation port 11, the special-shaped clip-on strip 9 is embedded and snap-connected to the clip-on groove 10 provided on the inner wall of the installation port 11, and a groove corresponding to the special-shaped clip-on strip 9 is provided in the middle of the clip-on groove 10.

[0032] Furthermore, a recessed platform 7 is formed at one end of the main plug post 41 , one end of the recessed platform 7 is fitted with the convex seat 6 , and a docking groove 61 is formed at the upper portion of the convex seat 6 .

[0033] Furthermore, when the plug-in sleeve 3 is connected to the installation opening 11, the clamping block 82 is clamped and connected to the plug-in sleeve 3. The clamping block 82 limits the plug-in sleeve 3, and cooperates with the locking shell 2 to continuously tighten the pressing plate 8, which can ensure the stability of the connection between the two.

[0034] Furthermore, the main terminal 411 is connected to the power connection module 101 through the threaded wall 5. The threaded connection ensures the stability of the connection between the two.

[0035] In this embodiment, the charging gun body 1 transmits current to the terminal assembly 4 in the plug-in barrel 3 through the power connection module 101. At the same time, in actual use, the terminal assembly 4 includes a main terminal 411 and a secondary terminal 421, wherein the main terminal 411 is screwed into the power connection module 101 through a threaded wall 5. During later maintenance, a cross screwdriver is used to engage and rotate the docking groove 61 on the protrusion 6, so that the main terminal 411 is rotated and removed to the outside, and because the protrusion 6 fits with the recess 7, a certain stability can be provided after the main terminal 411 is installed.

[0036] At the same time, the locking shell 2 can be disassembled, and the special-shaped snap-in strips 9 on both sides of the plug-in tube 3 can be pushed outward at the same time with the help of tools. A protrusion is provided in the middle of the special-shaped snap-in strip 9, and in the process of pushing it outward, its protruding end is gradually flattened, so that the special-shaped snap-in strip 9 is no longer embedded in the snap-in groove 10 opened on the inner wall of the installation port 11. At this time, the plug-in tube 3 is pulled out with force, so that the plug-in tube 3 is separated from the restriction of the bottom snap-in block 82, and because the snap-in block 82 is no longer subject to the compression and limitation of the locking shell 2, the snap-in block 82 can move freely in the limiting groove 13 opened at the bottom of the installation port 11, and then the plug-in tube 3 can be pulled out.

[0037] Among them, during actual use, when the plug-in tube 3 is connected to the installation port 11, the raised end of the special-shaped clamping strip 9 is clamped and installed in the clamping groove 10 to complete the locking. At the same time, during the advancement of the plug-in tube 3, the plug-in tube 3 presses down the clamping block 82, and after the docking is completed, the clamping block 82 fits and clamps with the plug-in tube 3. At this time, the locking shell 2 is put on to make the connection between the two tighter.

[0038] In actual use, a pressing plate 8 is flexibly connected in the pressing groove 12, and the pressing plate 8 can move freely up and down within a certain range, so that the clamping block 82 can move in the limiting groove 13. At the same time, the rubber strip 81 arranged at the bottom can ensure the installation stability of the locking shell 2 and prevent it from sliding.

[0039] In the utility model, the main terminal 411 is provided with a threaded wall 5 at the tail and cooperates with the boss 6 and the docking groove 61. When the main terminal 411 needs to be replaced, the docking groove 61 is clamped and rotated by a tool and the main terminal 411 is threadedly connected to the power connection module 101. The disassembly and assembly process is convenient and quick, and the plug-in tube 3 can be disassembled from the charging gun body 1 by removing the locking shell 2 and pulling out the special-shaped clamping strip 9. Compared with the traditional integrated charging gun, this mechanism can quickly disassemble the terminal assembly 4 and can also disassemble the main terminal 411 and the auxiliary terminal 421, which effectively improves the maintenance efficiency and ensures the stability of use.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
