Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electrical equipment, and specifically relates to a novel connection type straight insertion stepping motor. BACKGROUND

[0002] In the traditional motor design, the circuit connection and the common end processing usually depend on the PCB board. However, the use of the PCB board has many disadvantages. On the one hand, the PCB board increases the structural complexity of the motor, and the numerous parts not only increase the assembly difficulty in the manufacturing process, but also make the overall volume of the motor difficult to effectively reduce, which is not conducive to the miniaturization of the motor. On the other hand, with the increase of the number of parts, the manufacturing cost of the motor increases substantially, including the procurement cost of the PCB board itself and the labor cost in the assembly process. At the same time, as a relatively complex electronic component, the PCB board has a high probability of failure, and once a failure occurs, it is easy to cause damage to the motor, which seriously affects the reliability and stability of the motor, which is a problem that cannot be ignored in various application scenarios with extremely high requirements for motor stability.

DETAILED DESCRIPTION

[0012] The utility model will be further described with reference to the drawings.

[0013] As Figs. 1 to 3 The motor is provided with a skeleton 1 that plays a supporting role. This skeleton 1 provides stable support for the internal structure of the motor; inside the skeleton 1, a rotor 2 is installed. Outside the skeleton 1, two groups of winding type windings 3 are wound. The two groups of winding type windings 3 are respectively connected to two groups of guide needles 4 provided on the skeleton 1. The guide needles 4 serve as a bridge for connecting the winding type windings 3 to the external circuit and have good electrical conductivity. The innovation of the utility model lies in that a series connection circuit 5 is provided between the two groups of guide needles 4. In traditional motor design, a PCB board is usually used to realize circuit connection and common end processing. However, the utility model ingeniously connects the original common end, that is, the two groups of guide needles 4 in series by using the series connection circuit 5. In this way, the use of the PCB board is successfully saved. This improvement not only simplifies the structure of the motor, reduces the number of parts, and reduces the manufacturing cost, but also improves the overall reliability and stability of the motor, reduces the risk of motor damage caused by PCB board failure. At the same time, it also provides more favorable conditions for the miniaturization and lightweight design of the motor, so that it can better adapt to various complex application scenarios and installation requirements.

[0014] In this embodiment, the motor is also provided with a casing 6 and a straight insertion type wire protection box 7. The straight insertion type wire protection box 7 has staggered clamping blocks 8 on both sides, and the casing 6 is provided with a window 601 corresponding to the straight insertion type wire protection box 7. When the straight insertion type wire protection box 7 is inserted into the window 601 through the clamping blocks 8 on both sides, it can be firmly fixed on the casing 6, forming a complete and stable whole, and can be wrapped around the periphery of the guide needle 4 to provide protection.

[0015] In addition, the wire harness port 701 is also provided on the direct insertion wire protection box 7. The wire harness port 701 is an important interface for connecting the motor and the external wire harness 9. The wire harness port 701 is provided with clamping grooves 702 on both sides, which can be matched with the elastic buckles 901 on the wire harness 9. When the wire harness 9 needs to be connected, the elastic buckles 901 of the wire harness 9 are only needed to be aligned with the clamping grooves 702 and inserted gently, so that the quick connection of the wire harness 9 is completed. This connection mode is not only simple to operate, but also firm in connection, which can effectively prevent the wire harness 9 from loosening or falling off during use, and ensures the stable power transmission between the motor and the external equipment.

These descriptions are only for explaining the principles of the utility model, and cannot be interpreted as limiting the protection scope of the utility model in any way. Based on the explanations herein, other specific embodiments of the utility model can be conceived by those skilled in the art without creative labor, and these embodiments will all fall within the protection scope of the claims of the utility model.
