[0037] Please refer to Figures 1 to 7 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a main body 10, a plurality of terminals 20, and two latches 30.

[0038] The main body 10 has an upward-facing slot 11, within which multiple terminal slots 12 are formed. Both ends of the main body 10 have locking slots 13 communicating with the slot 11. Each locking slot 13 contains a shaft hole 14. In this embodiment, the shaft hole 14 is a through hole, designed so that a pin can push the connecting shaft 34 out of the shaft hole 14, facilitating the disassembly of the locking buckle 30. Additionally, a fixing groove 15 is formed on the lower side of the main body 10, within which a fixing member 40 is provided, effectively enhancing the strength of the main body 10 and preventing the main body from... 10 exhibits a back-and-forth swaying motion; specifically, the fixing member 40 extends downward with two fixing feet 41, and a first groove 42 is provided between the two fixing feet 41 to enhance the elasticity of the fixing feet 41 and give the fixing feet 41 a buffering effect. A second groove 43 is provided on the outer side of the extension of the two fixing feet 41 to enhance the elasticity of the fixing feet 41. When a back-and-forth swaying occurs, the elasticity can be restored and the main body 10 can be reset. A third groove 44 is provided on the upper side of the fixing member 40 to provide deformation space inside the main body 10 and prevent the main body 10 from deforming as much as possible.

[0039] The multiple terminals 20 are respectively disposed in the corresponding terminal slots 12, the contact portion 21 of each terminal 20 extends into the slot 11 from the terminal slot 12, and the solder portion 22 of each terminal extends downward from the lower side of the main body 10.

[0040] The two latches 30 are respectively installed in the latch grooves 13. Each latch 30 includes an integrally formed first latch portion 31, a body portion 32, and a second latch portion 33. The first latch portion 31 is exposed outside the latch groove 13, and the body portion 32 is located inside the latch groove 13. The body portion 32 has a connecting shaft 34, which is inserted into the shaft hole 14 for axial connection. The connecting shaft 34 has a first inclined portion 341 and a second inclined portion 342. The thickness of the first inclined portion 341 gradually decreases from top to bottom, and the thickness of the second inclined portion 342 gradually decreases from the outside to the inside. Specifically... The thickness of the second inclined portion 342 of the latch 30 installed on the left side of the main body 10 gradually decreases from left to right, while the thickness of the second inclined portion 342 of the latch 30 installed on the right side of the main body 10 gradually increases from left to right. The second latch portion 33 can be installed at the lower end of the latch groove 13, which can enter or leave the slot 11. In this embodiment, the cross-section of the connecting shaft 34 is a partially circular shape. The design of the partially circular shape can reduce the contact area between the connecting shaft 34 and the inner wall of the latch groove 13 during assembly, thereby reducing the strength it bears during assembly. Furthermore, the first latch portion 31 is provided with multiple steps 311.

[0041] The assembly process of this embodiment is described in detail below:

[0042] If the operator is accustomed to performing the assembly process first, the second locking part 33 first enters the locking groove 13 downwards, and the locking 30 moves downwards. Then, the first inclined part 341 contacts the opening edge of the locking groove 13. During the downward movement of the locking 30, the first inclined part 341 opens the locking groove 13 and contacts the inner wall of the locking groove 13. After moving downwards to the correct position, the operator moves the locking 30 to the left or right. The specific direction of movement depends on whether the locking 30 is installed on the left or right side of the main body 10. After moving to the correct position, the locking 30 is moved downwards again, and the connecting shaft 34 enters the shaft hole 14.

[0043] If the operator is accustomed to performing the left and right assembly processes first, the operator first moves the latch 30 to the left or right. The specific direction of movement depends on whether the latch 30 is installed on the left or right side of the main body 10. The second inclined surface 342 contacts the opening edge of the latch groove 13. During the movement of the latch 30 to the left or right, the second inclined surface 342 opens the latch groove 13. After the movement is in place, the latch 30 is then moved downwards. After the downward movement is in place, the latch 30 is then moved to the left or right, so that the connecting shaft 34 enters the shaft hole 14.

[0044] It is evident that the design of the two beveled surfaces can meet the needs of operators with different operating habits, bringing more convenience to the installation of the lock.

[0045] The key design feature of this utility model is:

[0046] By setting a first inclined surface and a second inclined surface on the connecting shaft, the thickness of the first inclined surface gradually decreases from top to bottom, and the thickness of the second inclined surface gradually decreases from the outside to the inside. During the assembly of the latch and the main body, the design of the two inclined surfaces allows the connecting shaft to slowly open the latch groove in both the vertical assembly direction and the horizontal direction, and quickly assemble the latch onto the main body. This satisfies the operating habits of different assemblers, and assembly can be achieved without applying a large force. The connecting shaft is subjected to relatively weak strength, which will not cause the connecting shaft to be scratched or cracked.

[0047] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
