Description

Technical Field

[0001] The utility model relates to the technical field of stepping motors, and more specifically to a stepping motor connecting wire and a stepping motor. Background Art

[0002] At present, the common stepper motor connection wires are mostly external PVC sleeves wrapped around the wire cores, while the internal wire cores are scattered. The structure of the entire connection wire is fixed by tying the PVC sleeve tightly with a cable tie, which has the following problems:

[0003] 1. Even if the PVC sleeve is tied with a cable tie, there is still a risk of loosening and sliding during transportation or use; and the exposed length of the cable tie section should not be too long, otherwise the cable tie will easily fall off, resulting in a deviation in the exposed length of the connecting wire core, which cannot meet the requirements;

[0004] 2. Since the internal wire cores are in a dispersed state, the wire core sequences cross each other during threading, which can easily lead to errors in the wire core sequence threading. It is necessary to subsequently increase the manual detection of the wire sequence process, which increases the cost.

[0005] 3. Due to its thin wall thickness, the PVC casing is prone to wear and tear in an environment with large burrs, and has poor wear resistance, which can cause damage to the internal wire core. Severe wear can cause the connecting line to fail. Utility Model Content

[0006] The technical problem to be solved by the utility model is how to prevent the wire core from loosening so as to stabilize the wire core sequence, avoid wire core sequence threading errors, accurately control the exposed length of the wire core, and avoid wear in an environment where the cape has large burrs.

[0007] The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0008] In order to solve the above technical problems, the utility model provides a stepper motor connecting wire, which includes a wire core and a sheath, wherein there are at least 4 wire cores and they are arranged in sequence; the sheath completely wraps all the wire cores and the gaps between adjacent wire cores.

[0009] As a preferred implementation of the stepper motor connecting wire provided by the utility model, the outer sheath is an insulating outer sheath.

[0010] As a preferred implementation of the stepper motor connecting wire provided by the utility model, the outermost layer of each wire core is provided with an insulating shielding layer.

[0011] As a preferred implementation of the stepper motor connecting wire provided by the utility model, all the wire cores are stacked into multiple layers.

[0012] As a preferred implementation of the stepper motor connecting wire provided by the utility model, the wire cores at both ends are exposed outwards.

[0013] As a preferred implementation of the stepper motor connecting wire provided by the utility model, the material of the outer sheath is PVC or PE.

[0014] As a preferred implementation of the stepper motor connecting wire provided by the utility model, the thickness of the outer sheath is 0.3mm-1.2mm.

[0015] A stepper motor comprises the stepper motor connecting wire as described in any one of the above items.

[0016] As a preferred implementation of the stepping motor provided by the utility model, one end of the wire core is connected to a plastic shell, a terminal is arranged inside the plastic shell, and a locking piece is arranged below the plastic shell.

[0017] As a preferred embodiment of the stepper motor provided by the utility model, an upper baffle and a lower baffle are arranged on the side of the plastic shell, a slider is arranged on the side of the locking plate, and the slider can be arranged between the upper baffle and the lower baffle.

[0018] The utility model has the following beneficial effects:

[0019] Because the outer sheath completely wraps the wire core, the wire core is completely confined inside the outer sheath to avoid the risk of loosening and sliding, thereby stabilizing the wire core sequence. The wire core sequence will not cross each other during threading, preventing the wire core sequence from being threaded incorrectly. There is no need to add manual detection of the connection line sequence process in the future, which reduces costs, and the exposed length of the wire core can also be accurately controlled; the outer sheath is thicker and will not wear out even when encountering large burrs. It has good wear resistance, avoids damage to the internal wire core, and thus avoids failure of the connecting line. And because the gaps between adjacent wire cores are also completely wrapped by the outer sheath, it further avoids loosening of the wire core and stabilizes the wire core sequence.
