Description

TECHNICAL FIELD

[0001] The utility model relates to driver technical field, especially a kind of driver and motor comprising it. BACKGROUND

[0002] Motor driver is a kind of execution mechanism that converts electric pulse into angular displacement, when receiving a pulse signal, it drives stepper motor to rotate a fixed angle (referred to as "step angle") in the set direction, its rotation is step by step with fixed angle, can control angular displacement by controlling pulse number, to achieve the purpose of accurate positioning, while can control the speed and acceleration of motor rotation by controlling pulse frequency, to achieve the purpose of speed regulation and positioning.

[0003] The existing driver needs to be connected with a large number of cables when in use, and the cables are inserted into the wiring port of the motor driver. Since the interface does not have a mechanism for limiting the cables, the cables are easily separated from the inside of the wiring port under the external pulling force, so that the motor driver cannot be used normally. Therefore, the utility model provides a driver and a motor comprising the same to meet the needs. UTILITY MODEL CONTENTS

[0004] To solve the above technical problems, the utility model provides the following technical scheme:

[0005] A driver includes a driver body, a mounting plate fixedly connected to the back of the driver body, a heat dissipation fin plate fixedly connected to the bottom of the driver body, a top plate fixedly connected to the top of the driver body, a wire insertion hole formed in the front of the driver body, and a fixed plate bolted to the front of the driver body.

[0006] Optionally, the limiting assembly includes a mounting slot formed in the front of the driver body, the mounting slot is located directly in front of the wire insertion hole, guide columns are fixedly connected to the two sides of the mounting slot, two guide plates are symmetrically and slidably connected to the outside of the guide columns, and reset springs are fixedly connected to the side of the two guide plates facing the mounting slot.

[0007] Optionally, guide grooves adapted to the guide columns are formed in the two sides of the guide plates, and the reset springs are in the shape of a Chinese character "".

[0008] Optionally, a square butt joint hole is formed in the inside of the fixed plate, the square butt joint hole is located directly in front of the wire insertion hole, inclined guide springs are fixedly connected to the front of the two guide plates, and the two guide springs are located in the inside of the square butt joint hole.

[0009] Optionally, a guide surface is formed on the contact surface of the two baffles, and a wire limiting hole is formed in the guide surface

[0010] The application further provides a motor comprising the driver, and the motor comprises a motor body, characterized in that a limiting groove is formed at the bottom of each side of the motor body, and two limiting plates are symmetrically and fixedly connected to the top of the top plate.

[0011] Optionally, a limiting protrusion is arranged on the opposite surface of each of the two limiting plates, a deformation cavity is formed in the limiting protrusion, and the limiting protrusion is tightly attached to the inner wall of the limiting groove.

[0012] Compared with the prior art, the utility model has at least the following beneficial effects:

[0013] In the above scheme, when the cable is inserted into the wire insertion hole, the baffle will intelligently slide outward, and the reset spring will deform to absorb the insertion force of the cable. Once the cable is completely inserted, the reset spring quickly recovers the deformation and pushes the baffle to tightly attach to the cable. This mechanism effectively prevents the cable from being accidentally detached under external tension, greatly improves the stability and reliability of the connection, and keeps the baffle closed in the non-use state, naturally forming a barrier and effectively preventing dust, debris and other external factors from entering the wire connection port, thereby playing a good dustproof role and prolonging the service life of the driver.

[0014] In the above scheme, the presence of the guide spring makes the insertion process of the cable smoother and more intuitive. The cable only needs to be inserted according to the guide direction of the guide spring, and can quickly and accurately reach the wire insertion hole, greatly improving the convenience of operation. In addition to the limiting function, the baffle also serves as a protective layer for the cable. After the cable is inserted and fixed, the baffle tightly attaches to the surface of the cable, reducing the direct contact between the cable and the external environment and reducing the risk of accidental damage to the cable.

[0015] In the above scheme, the limiting groove of the motor part cooperates with the limiting plate and the limiting protrusion on the driver to form a stable connection structure. This design allows the motor to be fixed with the driver when not in use, avoiding the loss or damage of parts caused by separate storage. BRIEF DESCRIPTION OF DRAWINGS

[0024] As shown in Figures 1 to 4 The inside of the fixed plate 7 is provided with a square butt joint hole, which is located in front of the wire insertion hole. The front surface of the two baffle plates 602 is fixedly connected with two inclined guide springs 603, which are located inside the square butt joint hole. The contact surface of the two baffle plates 602 is provided with a guide surface 605, and the inside of the guide surface 605 is provided with a wire limiting hole 607. Each wire limiting hole 607 is located in front of a single wire insertion hole. When the cable approaches the wire insertion hole, it first contacts the guide spring 603. Since the guide spring 603 is inclined, it will guide the cable to enter the square butt joint hole along a predetermined path. With the further insertion of the cable, the guide spring 603 is subjected to the thrust of the cable and begins to elastically deform, while pushing the two baffle plates 602 to slide outward along the guide column 601. In this process, the return spring 604 is also compressed and stores elastic potential energy. When the head of the cable enters the wire insertion hole, the side of the cable begins to contact the guide surface 605. The design of the guide surface 605 enables the cable to smoothly transition to the position of the wire insertion hole. With the complete insertion of the cable, the return spring 604 begins to release the stored elastic potential energy, pushing the baffle plate 602 to move closer to the center until it tightly fits the cable. At this time, the wire limiting hole 607 completely surrounds the corresponding part of the cable and forms a tight contact with the cable, thereby limiting the movement of the cable in the horizontal direction. Under the joint action of the return spring 604 and the baffle plate 602, the cable is firmly fixed in the wire insertion hole. At the same time, the square butt joint hole and the guide spring 603 also play a role in preventing the cable from being accidentally pulled out. Through the guidance of the guide spring 603 and the limiting effect of the baffle plate 602, the cable can be accurately inserted into the wire insertion hole and remain stably connected, effectively preventing the cable from loosening and falling off. When there is no cable inserted, the baffle plate 602 and the square butt joint hole form a closed dustproof structure together, effectively blocking the entry of dust and debris. The design of the guide surface 605 and the wire limiting hole 607 reduces the direct contact area and friction between the cable and the internal structure of the driver, reducing the risk of cable wear. The inclined guide spring 603 makes the cable insertion process smoother and more intuitive, and the user can easily insert the cable into place without much effort.

Since the inside of the limit protrusions is provided with the deformation cavity, it can adapt to a certain position deviation and slight deformation in the installation process, and ensure the smooth installation. When the limit protrusions completely enter the limit groove 501 and are tightly combined with the inner wall, the connection between the motor body 5 and the driver is completed. At this time, the limit protrusions and the limit groove 501 jointly form a stable connection structure, which ensures the relative position stability between the motor and the driver.
