[0026] Embodiment 1:

[0027] Please pay attention to Figures 1 to 5A pin connection terminal comprises a male terminal 1 and a female terminal 2, wherein the male terminal 1 comprises a first end tail 11 and an inner tube head 12, wherein the inner tube head 12 is fixedly mounted on the right end face of the first end tail 11, wherein the outer wall of the inner tube head 12 is symmetrically provided with a clamping assembly 3, wherein a pin terminal 13 is arranged inside the inner tube head 12, wherein the female terminal 2 comprises a second end tail 21 and an outer tube head 22, wherein the outer tube head 22 is fixedly mounted on the left end face of the second end tail 21, wherein the outer tube head 22 is symmetrically provided with an unlocking assembly 4, wherein a connecting end sleeve 23 is arranged inside the outer tube head 22, wherein the pin terminal 13 can be inserted into the inside of the connecting end sleeve 23.

[0028] Specifically, the design of the clamping component 3 can firmly connect the male terminal 1 and the female terminal 2 together, and the unlocking component 4 can release the male terminal 1 and the female terminal 2 in the locked state to facilitate disassembly.

[0029] Please pay attention to Figure 1 The ends of the first end tail 11 and the second end tail 21 that are away from each other are respectively provided with a first cable groove 111 and a second cable groove 211 that are recessed inwardly. This design allows cables to be connected for power supply.

[0030] The chamfer between the right end face of the inner tube head 12 and the outer wall is designed to be arc-shaped; the chamfer between the left end face of the outer tube head 22 and the inner wall is designed to be arc-shaped. The arc-shaped design can easily and quickly plug the male terminal 1 and the female terminal 2 together.

[0031] The outer wall of the pin terminal 13 is provided with a cushion block 131 , and the design of the cushion block 131 can play a certain protective role on the connection end sleeve 23 during multiple plugging and unplugging processes.

[0032] The connection end sleeve 23 is provided with a plug-in slot 231 connected to the pin terminal 13 . This design enables the pin terminal 13 to be connected.

[0033] The outer wall of the inner tube head 12 is symmetrically provided with an inwardly recessed mounting hole 121, and the clamping assembly 3 includes an arc-shaped metal spring piece 31 symmetrically installed in the mounting hole 121, and a clamping head 32 is provided on the symmetrically arranged arc-shaped metal spring piece 31, and the clamping head 32 extends out of the mounting hole 121. The arc-shaped metal spring piece 31 is provided with the clamping head 32, which can enable the clamping head 32 to clamp the outer tube head 22, thereby achieving the purpose of stably installing the male terminal 1 and the female terminal 2.

[0034] The inner wall of the outer tube head 22 is symmetrically provided with limiting holes 221 , and the limiting hole 221 is provided with a through groove 222 penetrating the outer wall of the outer tube head 22 . The limiting hole 221 is designed to be connected to the clamp 32 to achieve the function of connecting the outer tube head 22 .

[0035] The unlocking component 4 includes an arc-shaped pressing block 41, and an unlocking rod 42 slidably installed in the through groove 222 is arranged inside the arc-shaped pressing block 41. The inner wall of the arc-shaped pressing block 41 is provided with a spring 421 surrounding the unlocking rod 42, and the other end of the spring 421 is fixedly connected to the outer wall of the outer tube head 22. The design of the unlocking component 4 can release the male terminal 1 and the female terminal 2 in the plugged state.

[0036] The specific operation method of the utility model is as follows: when in use, first install the two cables in the first cable groove 111 and the second cable groove 211 respectively, then grab the first end tail 11 and align the inner tube head 12 with the outer tube head 22. When the centers of the inner tube head 12 and the outer tube head 22 are on the same horizontal line, the first end tail 11 can be pushed toward the direction of the outer tube head 22, so that the inner tube head 12 is plugged into the outer tube head 22. When it is fully plugged into place, the pin terminal 13 will be in the plug-in groove 231 of the connecting end sleeve 23. When the inner tube head 12 is inserted into the outer tube head 22, the clamping head 32 contacts the inner wall of the outer tube head 22, is squeezed, and begins to shrink toward the mounting hole 121. At the same time, the arc-shaped metal spring piece 31 will also be deformed due to squeezing. Until it is fully installed in place, the arc-shaped metal spring piece 31 rebounds and fits the clamping head 32 into the limiting hole 221 to improve the firmness of the plug-in connection between the male terminal 1 and the female terminal 2.

[0037] When it is necessary to release the male terminal 1 and the female terminal 2 in the plugged state, first press the arc-shaped pressing block 41 in opposite directions, and the synchronous unlocking rod 42 will press the clamping head 32 into the mounting hole 121. When the clamping head 32 is in the mounting hole 121, the male terminal 1 and the female terminal 2 can be separated.
