[0030] In current technology, the connection between the motor leads and the internal components is prone to breakage due to external pulling, leading to poor contact or short circuit risks, and subsequent maintenance is very inconvenient. On the other hand, the fixed length of the leads makes it difficult to replace them with different lengths, limiting the flexibility of motor layout in different operating environments.
[0031] The following is a preferred embodiment of a motor provided by this utility model that can solve the above-mentioned technical problems.
[0032] Please refer to Figure 1 and Figure 2 In the diagram, units with similar structures are represented by the same labels.
[0033] This embodiment provides a motor, which includes a housing 11, a wiring structure, a first coil assembly 14, and a second coil assembly 15.
[0034] The housing 11 has a mounting port on one side of its circumference, and the wiring structure is located at the mounting port. The first coil assembly 14 and the second coil assembly 15 are stacked inside the housing 11. The first coil assembly 14 has multiple terminals 16 extending from the side near the mounting port, and the wiring structure includes a terminal housing 13 and a fixing housing 12.
[0035] The fixed housing 12 is detachably encapsulated and connected to the mounting port. A mounting groove 122 is provided on one side of the fixed housing 12. The terminal housing 13 is detachably connected in the mounting groove 122, which facilitates the replacement of different models of terminal housing 13 to connect with different models of external plugs. The plug-in compatibility is high, and the terminal housing 13 is easy to replace if it is damaged.
[0036] The terminal housing 13 has a terminal hole 131 corresponding to each terminal post 16. The end of the terminal post 16 away from the coil assembly extends through the fixing housing 12 into the terminal hole 131. The terminal housing 13 is used to connect to an external plug so that multiple terminals 16 are electrically connected to the plug. In this way, the conductive leads are not directly connected to the coil assembly, and the electrical connection between the conductive leads and the coil assembly is less likely to be damaged or fail. The external plug can have leads of different lengths, which facilitates flexible layout in different usage environments.
[0037] Please refer to Figure 2 In this embodiment, slots 1221 are provided on two opposite side walls of the mounting groove 122. Receiving holes extending into the terminal holes 131 are provided on both sides of the terminal housing 13. An elastic plate 132 is provided within each receiving hole. A pressure block protruding into the terminal hole 131 is provided on one side of the elastic plate 132, and a fixing block 133 for engaging with the slots 1221 is provided on the other side of the elastic plate 132. The elastic movement of the elastic plate 132 facilitates the assembly and disassembly of the terminal housing 13 from the fixed housing 12.
[0038] When the terminal housing 13 is not plugged into an external plug, the fixing block 133 is engaged in the slot 1221, and the side of the fixing block 133 away from the terminal hole 131 is at a set initial distance from the inner wall of the slot 1221. At this time, the terminal housing 13 can form a certain connection with the fixed housing 12 through the engagement of the fixing block 133 and the slot 1221, and at the same time, the terminal housing 13 can be easily disassembled from the fixed housing 12.
[0039] When the terminal housing 13 is plugged into the external plug, the external plug presses the pressure block and moves it closer to the slot 1221. The distance between the fixing block 133 and the inner wall of the slot 1221 is less than the initial set distance. That is, the pressure of the external plug causes the fixing block 133 to further engage with the slot 1221, making the engagement more secure. In this way, after the external plug is inserted into the terminal housing 13, the terminal housing 13 is less likely to detach from the fixing housing 12, and the connection structure is very stable.
[0040] In this embodiment, one end of the terminal housing 13 includes a holding portion 134, which is located outside the mounting groove 122. The width of the end of the holding portion 134 away from the mounting groove 122 is greater than the width of the end close to the mounting groove 122. By operating the holding portion 134, it is convenient to disassemble and assemble the terminal housing 13.
[0041] The mounting slot 122 connects to the terminal housing 13, and the insertion slot faces the same direction as the axial direction of the housing 11. A clearance groove is provided on one side of the fixed housing 12 near the insertion slot. The holding part 134 is located in the clearance groove, making the connection structure between the terminal housing 13 and the fixed housing 12 more compact and less obtrusive.
[0042] Please refer to Figure 2 In this embodiment, the mounting groove 122 penetrates the side of the fixed housing 12 along the radial direction of the housing 11 to form a through opening, so that the two side walls of the mounting groove 122 with the slot 1221 have contraction and expansion properties, making it easy to assemble and disassemble the terminal housing 13 from the mounting groove 122. The side of the terminal housing 13 facing the through opening is flush with the side of the fixed housing 12, so that the overall structure of the terminal housing 13 and the fixed housing 12 is good after connection.
[0043] Please refer to Figure 2 In this embodiment, the terminal 16 has a Z-shaped structure, and the middle part of the terminal 16 is connected to the fixed housing 12. The fixed housing 12 can provide stable support for the terminal 16 so that the terminal 16 can be stably plugged into the external plug and is less likely to damage the connection between the terminal 16 and the first coil assembly 14.
[0044] In this embodiment, there are five terminals 16, arranged in a line on one side of the first coil assembly 14. The two outer terminals 16 are connected to the conductive wires of the first coil assembly 14, the middle terminal 16 is connected to the conductive wires of both the first coil assembly 14 and the second coil assembly 15, and the remaining two terminals 16 are connected to the conductive wires of the second coil assembly 15. The middle terminal 16 is used to connect to the COM terminal (common terminal) for controlling the forward and reverse rotation of the motor.
[0045] In this embodiment, the first coil assembly 14 includes a first fixing frame 141, and five terminals 16 are arranged in a row on one side of the first coil assembly 14. The side of the first fixing frame 141 where the terminals 16 are provided is provided with a plurality of first wire grooves 1411. The first wire grooves 1411 are used to guide the conductive wires of the first coil assembly 14 and the conductive wires of the second coil assembly 15.
[0046] The second coil assembly 15 includes a second fixing frame 151, and a second wire groove 1511 is provided on one side of the second fixing frame 151. The second wire groove 1511 is used to guide the conductive wire of the second coil assembly 15.
[0047] The first wire groove 1411 and the second wire groove 1511 are used to allow the conductive wire to extend more stably to connect with the terminal 16.
[0048] In this embodiment, a locking plate 123 is provided on both sides of the fixed housing 12, and a locking hole 1231 is provided on the locking plate 123. The first fixing frame 141 is provided on both sides with locking blocks for engaging with the locking hole 1231, so that the fixed housing 12 and the first fixing frame 141 are fixedly connected.
[0049] In this embodiment, positioning plates 121 are provided on both sides of the fixed housing 12, the clamping plate 123 contacts the inner wall of the housing 11, and the positioning plate 121 contacts the outer wall of the housing 11, so that the fixed housing 12 is stably encapsulated and connected to the mounting port of the housing 11.
[0050] In this embodiment, the housing 11 includes a main housing 111 and a cover 112 connected to one end of the main housing 111, and the second coil assembly 15 is located between the first coil assembly 14 and the inner bottom wall of the main housing 111.
[0051] A limiting plate 124 is provided at one end of the fixed housing 12. The second coil assembly 15 is limited between the limiting plate 124 and the inner bottom wall of the main housing 111. The first coil assembly 14 is limited between the clamping plate 123 and the second coil assembly 15, so that the first coil assembly 14, the second coil assembly 15 and the fixed housing together form a stable connection structure with the housing 11.
[0052] The two ends of the limiting plate 124 protrude from the side of the fixed housing 12, and the limiting plate 124 contacts the inner wall of the housing 11.
[0053] The working principle of this embodiment is as follows: During assembly, the clamping plates 123 on both sides of the fixed housing 12 are first engaged with the clamping blocks on both sides of the first fixed frame 141. At the same time, the clamping plates 123 are in contact with the inner wall of the housing 11, the positioning plate 121 is in contact with the outer wall of the housing 11, and the limiting plate 124 is in contact with the inner wall of the housing 11.
[0054] Next, the terminal housing 13 is inserted into the mounting slot 122, which will cause the terminal post 16 to be inserted into the terminal hole 131. At the same time, during this process, the elastic plate 132 allows the fixing block 133 to move to the position where it engages with the slot 1221, so that the terminal housing 13 can form a certain connection with the fixing housing 12, and at the same time, the terminal housing 13 can be easily disassembled from the fixing housing 12.
[0055] When the external plug is inserted into the terminal housing 13, the external plug presses the pressure block and moves it closer to the slot 1221, causing the fixing block 133 to further engage with the slot 1221, making the engagement even tighter. In this way, after the external plug is inserted into the terminal housing 13, the terminal housing 13 is less likely to detach from the fixing housing 12, and the connection structure is very stable.
[0056] In this preferred embodiment, the wiring terminals of the motor extend into the terminal holes, allowing the external plug to be inserted into the terminal housing to achieve an electrical connection with the motor. This electrical connection is less prone to damage or failure. The external plug can have leads of different lengths, facilitating flexible layout in different usage environments. Furthermore, the terminal housing is detachably connected to the fixed housing, allowing for the replacement of different terminal housing models to connect with different types of external plugs, resulting in high compatibility and easy replacement if the terminal housing is damaged.
[0057] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
