Description

Technical Field

[0001] The present invention belongs to the technical field of heaters and relates to a wiring method for heater cables, and in particular to a wiring method for heater cables and a wire stripper. Background Art

[0002] In the field of heaters, the wiring method of cables is one of the key factors to ensure the performance and safety of the equipment. The traditional wiring method of heaters is usually to directly insert the cable into the PIN hole of the heater to achieve electrical connection. However, this wiring method has some significant defects, such as easy loosening and even virtual connection, which directly affects the performance and reliability of the heater.

[0003] Since the outer diameter of the heater cable is usually smaller than the inner diameter of the PIN hole, this size mismatch causes the cable to become loose in the PIN hole. The looseness of the cable not only leads to poor contact, but also increases the resistance, thus affecting the heating efficiency and stability of the heater. In some extreme cases, this poor contact can easily lead to safety hazards such as overheating, short circuit and even fire.

[0004] In addition, the traditional wiring method lacks precise control over the relationship between the cable size and the PIN hole size. In actual operation, it is very easy to cause the cable to be over-stretched or compressed, which in turn affects the electrical performance and mechanical strength of the cable. In addition, due to the lack of standardized stripping tools, operators are prone to damaging the conductor inside the cable when stripping the cable insulation layer, further increasing the instability of the wiring.

[0005] It can be seen that how to provide a wiring method and a wire stripping tool for a heater cable to improve the contact stability between the cable and the PIN hole and reduce performance problems and safety hazards caused by poor contact has become an urgent problem that technical personnel in this field need to solve. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a wiring method and wire stripper for a heater cable, which improves the contact stability between the cable and the PIN hole, reduces performance problems and safety hazards caused by poor contact, and is conducive to large-scale promotion and application.

[0011] (3) Insert the connection end obtained in step (2) into the PIN hole to complete the wiring operation.

[0012] Wherein, the clamping part of the wire stripper in step (2) is provided with at least one circular hole for clamping the folded end of the heater cable; the diameter of the circular hole is smaller than the inner diameter of the PIN hole, and the difference is 0.1-0.3mm.

[0013] The wiring method provided by the present invention achieves a stable connection between the cable and the PIN hole by folding the cable in half and accurately matching the aperture of the wire stripper, reduces performance problems and safety hazards caused by poor contact, and extends the service life of the heater. At the same time, it is easy to operate and does not require expensive and complicated wiring equipment, which is conducive to large-scale promotion and application.

[0046] The present invention limits the ratio of the force arms of the clamping part 1 and the pressure rod part 3 of the wire stripper, and fully utilizes the lever principle to amplify the force applied by the operator, so that the operator can achieve a larger clamping force of the clamping part 1 with a smaller force, thereby improving the operating efficiency.
