[0045] The invention discloses a method for connecting a circular wire and a terminal device. The invention facilitates the bridging between the circular wire and the terminal device by setting a connecting terminal structure, which not only ensures the stability of the connection between the circular wire and the terminal device, but also ensures the convenience of the connection between the circular wire and the terminal device.

[0046] Furthermore, in step 2 described in the present invention, a fastening bolt 31 in the locking mechanism 3 is first used to pre-tighten the round wire in the plug-in hole 21; after the pre-tightening of the round wire is completed; it is detected whether the round wire is plugged in place, and after it is plugged in place; the round wire is locked and fixed using each fastening bolt 31 in the locking mechanism 3; such an assembly method can ensure the stability of the connection between the round wire and the connecting sleeve 2, and ensure that the round wire is assembled in place in the connecting sleeve 2.

[0047] The connection terminal structure disclosed in the present invention mainly includes a connection plate 1, and a connection hole 11 is provided on the connection plate 1; a connection sleeve 2 is connected to the end of the connection plate 1, and the connection sleeve 2 includes a sleeve body 22, and a plug hole 21 is provided in the sleeve body 22, and a locking mechanism 3 is provided on the connection sleeve 2; the present invention discloses a convenient connection terminal structure, and the present invention can be directly used for connecting copper, aluminum, and aluminum alloy round wires with terminals through the coordinated use of the connection sleeve 2 and the connection plate 1.

[0048] Specifically, the connection terminal structure disclosed in the present invention mainly includes a connection plate 1, which mainly plays a basic connection role and is provided with a connection hole 11. The connection plate 1 can be directly connected to the device terminal through the connection hole 11 and the matching bolts. In addition, the connection plate 1 is connected to a connection sleeve 2, and the connection sleeve 2 is provided with a plug hole 21. The end of the connecting wire is plugged into the connection sleeve 2, thereby realizing the connection assembly between the wire and the terminal.

[0049] In addition, in the present invention, a locking mechanism 3 is also provided on the connecting sleeve 2. The setting of the locking mechanism 3 can ensure the stability of the connection of the wire in the connecting sleeve 2; specifically, in the present invention, the locking mechanism 3 includes a fastening bolt 31 provided on the connecting sleeve 2; the fastening bolt 31 passes through the sleeve body 22 of the connecting sleeve 2 and extends to the plug-in hole 21; the present invention finally achieves the stability of the installation of the wire in the connecting sleeve 2 by squeezing the fastening bolt 31.

[0050] In addition, in the present invention, the fastening bolt 31 includes a screw rod, a nut is provided at the end of the screw rod, and the nut adopts a structure similar to a twist-off nut. The design of the twist-off nut can ensure a good clamping torque while preventing damage to the wire.

[0051] Specifically, in the present invention, the locking mechanism of the present invention is a locking mechanism with a rated torque to break; in other words, the fastening bolt in the present invention is a torsion-off structure with a rated torque; specifically, the fastening bolt of the present invention includes a stud rod 314, a nut is provided at the end of the stud rod 314, the nut includes a lower nut 312 and an upper nut 311, the lower nut 312 is connected to the upper nut 311 through a fixed torque sleeve 313, the lower nut 312 is connected to the stud rod 314, during actual assembly, the upper nut 311 is clamped, the fastening bolt is tightened, and the fastening bolt is continuously rotated, and the fixed torque sleeve 313 is tightened. It can be designed according to needs, and the torque-fixing sleeve 313 has a certain torque bearing capacity. During specific assembly, a tool is used to clamp the upper nut 311. By rotating the upper nut 311, the upper nut 311 drives the lower nut 312 to rotate through the torque-fixing sleeve 313. When the fastening bolt continues to rotate, the fastening bolt squeezes and fixes the wiring harness. When continuously tightened, the tightening torque exceeds the bearing torque of the torque-fixing sleeve 313, and the torque-fixing sleeve 313 is damaged, thereby disconnecting the upper nut 311 and the lower nut 312, thereby preventing the fastening bolt from continuously squeezing the clamping block and damaging the wiring harness.

[0052] Furthermore, in the present invention, the connecting hole 11 is a waist-shaped hole; such a setting can make the connecting plate 1 have a certain adjustment ability when connected to the terminal, which greatly increases the scope of application of the present invention and improves the versatility of the present invention; based on such a setting, even if the wiring harness changes, the wiring harness can be clamped and fixed by replacing the lower clamp block, avoiding the cost waste caused by changing the upper clamp block.

[0053] Furthermore, in the present invention, at least two connecting holes 11 are provided on the connecting plate 1, and at least one connecting hole 11 on the connecting plate 1 is a waist-shaped hole; the connecting hole 11 of the present invention is designed as a waist-shaped groove in order to increase the adjustment ability of the connecting terminal structure. In addition, in the present invention, one connecting hole 11 can be designed as a circular hole. Such a setting can stably realize the connection and fixation between the connecting plate 1 and the terminal device; during the actual connection, through the cooperation of the circular connecting hole 11 and the waist-shaped connecting hole 11, it can be ensured that the connecting plate 1 can better realize the stable connection to the terminal device.

[0054] Furthermore, in the present invention, an internal thread is provided in the plug-in hole 21 ; the provision of the internal thread facilitates the stability of the wire plugged into the connecting sleeve 2 , and ensures the stability of the connection between the wire and the connecting sleeve 2 .

[0055] Furthermore, in the present invention, at least two fastening bolts 31 are provided on the connecting sleeve 2, and adjacent fastening bolts 31 are staggered. Such a design can realize the locking mechanism 3 squeezing the wire in different directions, and can better ensure the stability of the wire placed in the connecting sleeve 2.

[0056] Furthermore, in the present invention, a limiting plate 4 is provided at the end of the connecting plate 1, and a placement groove is provided on the limiting plate 4, and the connecting sleeve 2 is placed inside the placement groove of the limiting plate 4; here, the limiting plate 4 acts as a supporting rib to ensure the structural strength of the connection between the connecting sleeve 2 and the connecting plate 1; in addition, in the present invention, the connecting sleeve 2 and the connecting plate 1 can be designed as an integrated structure, and of course, they can also be made into a detachable connection method as needed, and the detachable connection method can be a snap-on connection or other connection methods.

[0057] In actual implementation, the connecting sleeve can be connected to the placement sink through threads; this connection method can realize the step-by-step connection between the connecting plate and the connecting sleeve, which facilitates the actual assembly of the entire device.

[0058] Furthermore, in the present invention, a protective pattern 12 is provided on the connecting plate 1; the provision of the protective pattern 12 increases the stability of the connection between the connecting plate 1 and the terminal device, and better ensures the stability of the connection of the connecting plate 1 on the terminal device; the protective pattern can be provided on multiple sides of the connecting plate, and the specific selection can be made according to needs.

[0059] Furthermore, in the present invention, a guide inclined surface 23 is provided on the side of the connecting sleeve 2 close to the connecting plate 1; such a configuration plays a good avoidance role and prevents the connecting sleeve 2 from interfering with the side of the terminal device.

[0060] Furthermore, in the present invention, the connecting sleeve 2, the connecting plate 1 and the limiting plate 4 are all coated with a tin coating; the surface tin plating can make the connection more conductive and more resistant to acid and alkali corrosion.
