The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0022] The following is combined with Figure 1-3 The utility model is described in further detail.

[0023] The utility model embodiment discloses a braided copper belt threading tool.

[0024] Reference Figure 1 , Figure 2 , Figure 3 A braided copper belt threading tool comprises a base, an upper clamping block 3 rotatably arranged on the base, and a locking assembly. The base is provided with a limit groove 1 5 adapted to the copper nose 7, and the upper clamping block 3 is provided with a limit groove 2 6. The limit groove 2 6 is used to limit the lateral displacement of the copper nose 7. The locking assembly is used to lock the upper clamping block 3 to the base. The upper clamping block 3 is buckled into the limit groove 1 5 and the limit groove 2 6 of the base to clamp the copper nose 7. The right side of the base and the upper clamping block 3 are both provided with a connecting hole 9 for the cable to pass through. Compared with the original manual threading process, the efficiency of threading is greatly improved by the braided copper belt threading tool, and the process is also simplified and safe. The products of the braided copper belt threading tool can well meet the production requirements.

[0025] The base is made of carbon steel, which has high strength, wear resistance and rigidity. The base includes a base 1 and a lower clamping block 2. The lower clamping block 2 is fixed on the base 1 by bolts, and the upper clamping block 3 is rotatably matched with the lower clamping block 2 by a latch.

[0026] The base is provided with a stopper 4, which is used to limit the inward movement of the copper nose 7, and the longitudinal section formed between the stopper 4 and the lower clamping block 2 is C-shaped. The stopper 4 is arranged on the left side of the lower clamping block 2, and the lower clamping block 2 is arranged on the right side of the base and the upper plane is higher than the upper plane of the stopper 4 to form a step. The limiting groove 1 5 is opened on the top of the lower clamping block 2, and the top of the copper nose 7 extends from the limiting groove 1 5 and is located in the step. The stopper 4 is used to limit the movement of the copper nose 7 to the left, and the step is used to limit the movement of the copper nose 7 to the right. The limiting groove 1 5 and the limiting groove 2 6 are used to limit the lateral displacement of the copper nose 7, and the overall positioning and fixing of the copper nose 7 is completed.

[0027] The locking assembly includes a buckle 8 and a spring. The buckle 8 is rotatably arranged on the upper clamp block 3. A slot is arranged on the lower clamp block 2. The buckle 8 can be clamped in the slot. The spring is a torsion spring, which is coaxially installed on the latch. The spring is used to apply an inward pre-tightening force to the buckle 8 so that the buckle 8 is clamped in the slot. When the buckle 8 is locked in the slot under the action of the spring, the upper clamp block 3 and the lower clamp block 2 are pressed against each other and the copper nose 7 is clamped. The buckle 8 can be fastened in the slot by the setting of the spring and fixed firmly.

[0028] An exhaust channel 10 is provided on the side wall of the limiting groove 1 5. An exhaust channel 2 11 is provided on the side wall of the limiting groove 2 6. After the upper clamping block 3 and the lower clamping block 2 are pressed against each other, the exhaust channel 10 and the exhaust channel 2 11 are connected to each other, and the exhaust channel 10 and the exhaust channel 2 11 are used to squeeze the excess air of the limiting groove 1 5 and the limiting groove 2 6 into the exhaust channel 1 10 or the exhaust channel 2 11, so that the upper clamping block 3 and the lower clamping block 2 are pressed against each other more tightly.

[0029] The connecting hole 9 is opened on the right side of the base and the right side of the upper clamping block 3, and is used for the cable to pass through the installation part of the copper nose 7. The cross section of the connecting hole 9 is conical, and the large end of the connecting hole 9 is located on the outside (right side) of the base. The conical design and the large end of the connecting hole 9 located on the right side of the base and the right side of the upper clamping block 3 can facilitate the insertion of the cable, and the cable is tightened through the gradually narrowing channel of the connecting hole 9, which is convenient for threading.

[0030] The installation steps are as follows:

[0031] Step 1: Open the upper clamping block 3 of the braided copper tape threading tooling, put the copper nose 7 into the limiting groove 5 of the lower clamping block 2, and the right stopper 4 is used to limit the copper nose 7 to limit the installation part of the copper nose 7 in the limiting groove 5, so that the position remains unchanged in subsequent processing;

[0032] Step 2: Close the clamp block 3 on the braided copper tape threading tool and buckle it with a locking assembly to lock the copper nose 7;

[0033] Step 3: Insert the prepared cable from the connecting hole 9 on the right;

[0034] Step 4: After the threading is completed, release the locking assembly, loosen the upper clamping block 3, and then open the threading tool to take out the threaded copper nose 7 and the cable.

[0035] Compared with the original manual threading process, the utility model uses a braided copper belt threading tool to greatly improve the threading efficiency, simplify the process and make it safer. The products of the braided copper belt threading tool can meet the production requirements well.
