Description

Technical Field

[0001] This utility model belongs to the technical field of power adapter equipment, specifically relating to an external power adapter for motors that is easy to wire. Background Technology

[0002] A power adapter is a device that converts household voltage into low-voltage power for small electrical appliances. Traditional power adapters mostly use screw-fastening connections. In practice, workers need to use screwdrivers and other tools to tighten screws to secure the wires. This process is extremely tedious, especially when wiring large quantities. A significant amount of time is spent on tightening screws, severely impacting work efficiency. Furthermore, motors often vibrate during operation, and prolonged exposure to this environment can easily cause screws to loosen, leading to poor wire contact. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing an external power adapter for motors that is easy to wire.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an external power adapter for motors that facilitates wiring, comprising a power housing with an inner cavity, a circuit board with a DC-AC conversion circuit being provided on the bottom inner side of the power housing, vertically arranged mounting notches being provided on opposite sides of both ends of the power housing and penetrating the end and side of the power housing, power cord connectors being provided in the mounting notches, the end of the circuit board extending into the mounting notch and being fixedly connected to the power cord connector, the power cord connector being provided with a plurality of wiring holes, the power cord connector being provided with terminals connected to the circuit board, and a quick-connect component being movably provided on the power cord connector to connect the power cord to the terminals when the power cord is inserted into the wiring hole.

[0005] In the aforementioned easy-to-wire external power adapter for motors, the power supply housing has a split rectangular box structure, consisting of an upper housing and a lower housing connected by a snap-fit ​​assembly. The mounting notch penetrates the upper housing and extends to the lower housing. This split rectangular box structure, with the upper and lower housings connected by the snap-fit ​​assembly, facilitates the assembly and disassembly of the power supply housing. When internal circuit boards and other components need to be inspected or maintained, the operation is more convenient, reducing maintenance costs. Simultaneously, the mounting notch, penetrating the upper housing and extending to the lower housing, ensures the integrity of the power cord connector installation position, avoiding misalignment or instability issues caused by the split housing design, and ensuring structural harmony.

[0006] In the aforementioned easy-to-wire external power adapter for motors, the snap-fit ​​assembly includes several upper snap-fit ​​pieces located at the lower opening of the upper housing, and several lower snap-fit ​​pieces corresponding one-to-one with the upper snap-fit ​​pieces located at the upper opening of the lower housing. Each upper snap-fit ​​piece has a snap-fit ​​portion on one side, and each lower snap-fit ​​piece has a slot for snap-fitting the snap-fit ​​portion. Through the design of the upper and lower snap-fit ​​pieces corresponding one-to-one and the snap-fit ​​portion engaging with the slot, a stable connection between the upper and lower housings is achieved. Compared to screw-based connections, the snap-fit ​​structure offers higher assembly efficiency, requires no additional tools, and simplifies the production process. Furthermore, the multiple sets of snap-fits allow for fixation of the housing from multiple positions, enhancing the stability of the housing connection and reducing the risk of loosening due to vibration during use.

[0007] In the aforementioned motor external power adapter that facilitates wiring, the mounting notch includes a rectangular upper notch respectively provided on the corner of the upper housing. The upper notch penetrates two adjacent sides of the upper housing, and one side of the upper notch penetrates the end face of the upper housing to form an upper mounting groove. The corner of the lower housing has a lower notch corresponding to the upper notch. The lower notch penetrates the end face of the lower housing to form a lower mounting groove that communicates with the upper mounting groove.

[0008] In the aforementioned easy-to-wire external power adapter for motors, the circuit board extends to the bottom of the lower notch, and the power cord connector is rectangular and installed within the lower notch, fixed to the circuit board. This achieves precise positioning of the power cord connector, preventing misalignment during installation and ensuring the accuracy of subsequent wiring operations.

[0009] In the aforementioned easy-to-wire external power adapter for motors, the upper end of the power cord connector does not extend beyond the upper notch, and one side of the power cord connector does not extend beyond the lower mounting slot. One power cord connector has a 210V-240V AC input port, and the other power cord connector has a 24V DC output port. This design avoids excessive extension of the power cord connector, reduces the risk of damage from external impacts, and prevents accidental contact, thus improving safety.

[0010] In the aforementioned easy-to-wire external power adapter for motors, the quick-connect assembly includes several push-buttons located on the upper end of the power cord connector and on one side of the wiring hole. The power cord connector contains a flexible connecting piece secured by a fixing component. The two sides of the flexible connecting piece are respectively connected to the wiring terminal and the power cord. The lower end of the push-button contacts the upper end of the flexible connecting piece, and a limiting part is provided circumferentially at the lower end of the push-button. The push-button design eliminates the need for tools such as screwdrivers during wiring; simply pressing the button connects the power cord to the wiring terminal, simplifying the wiring process and reflecting the design goal of easy wiring. The limiting part restricts the range of motion of the push-button, preventing it from detaching from the power cord connector.

[0011] In the aforementioned motor external power adapter that facilitates wiring, the fixing component includes a fixing post located below the push button, the wiring hole is located on one side of the fixing post, the other side of the fixing post is provided with a connecting piece insertion groove, and the upper end of the fixing post near the wiring hole has an inclined portion.

[0012] In the aforementioned easy-to-wire external power adapter for motors, one side of the elastic connecting piece has a vertical portion located within a connecting piece insertion slot. This vertical portion is connected to a terminal block. The upper end of the vertical portion has a pressing part that contacts a pressing button, and the end of the pressing part away from the vertical portion has an arc-shaped portion located within a wiring hole. The vertical portion inserts into the connecting piece insertion slot and connects to the terminal block, ensuring a stable connection to the circuit board. The pressing part contacts the pressing button, realizing the transmission logic of pressing operation, elastic piece deformation, and connection / disconnection.

[0013] In the aforementioned motor external power adapter that facilitates wiring, the bottom of the power housing is provided with several support blocks circumferentially, the circuit board is disposed on the upper end of the support blocks, and the upper side of the support blocks at both ends of the power housing is provided with guide protrusions corresponding to the two ends of the circuit board.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. This device, through the cooperation of a press button and a flexible connecting piece, allows for quick connection and disconnection of the power cord and the terminal block simply by pressing the button after the power cord is inserted into the wiring hole, without the need for tools such as screwdrivers. This greatly simplifies the wiring process and saves time and effort.

[0016] 2. The power supply housing of this device adopts a split rectangular box structure. The upper and lower housings can be quickly connected and separated through snap-fit ​​components. This facilitates the installation, inspection and maintenance of internal circuit boards and other components, and ensures the stability of the housing connection. Assembly can be completed without additional tools, improving production and maintenance efficiency.

[0017] 3. The installation notch of the device is located at the corner of the housing, which makes clever use of the corner space and avoids occupying the main internal space. At the same time, the cooperation of the upper and lower notches forms a continuous installation groove, providing a precise and stable installation position for the power cord connector, allowing the components to be distributed in an orderly manner within a limited space.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-5 As shown, an external power adapter for motors that facilitates wiring includes a power housing 1 with an inner cavity. A circuit board 11 with a DC-AC conversion circuit is provided on the bottom inner side of the power housing 1. Vertical mounting notches 12 are provided on opposite sides of both ends of the power housing 1, penetrating the ends and sides of the power housing 1. Power cord connectors 2 are provided in the mounting notches 12. The end of the circuit board 11 extends into the mounting notch 12 and is fixedly connected to the power cord connector 2. The power cord connector 2 is provided with a plurality of wiring holes 21. The power cord connector 2 is provided with terminals 22 connected to the circuit board 11. A quick-connect component 3 is movably provided on the power cord connector 2 so that the power cord can be connected to the terminals 22 when the power cord is inserted into the wiring hole 21.

[0026] Combination Figures 1-3 As shown, the power supply housing 1 has a split rectangular box structure, consisting of an upper housing 13 and a lower housing 14 connected by a snap-fit ​​assembly 4. An installation notch 12 penetrates the upper housing 13 and extends to the lower housing 14. This split rectangular box structure, with the upper housing 13 and lower housing 14 connected by the snap-fit ​​assembly 4, facilitates the assembly and disassembly of the power supply housing 1. When internal components such as the circuit board 11 need to be inspected or maintained, the operation is more convenient, reducing maintenance costs. Simultaneously, the installation notch 12, penetrating the upper housing 13 and extending to the lower housing 14, ensures the integrity of the power cord connector 2's installation position, avoiding misalignment or instability caused by the split housing design, and ensuring structural harmony.

[0027] The snap-fit ​​assembly 4 includes several upper snap-fit ​​pieces 41 located at the lower opening of the upper housing 13, and several lower snap-fit ​​pieces 42 located at the upper opening of the lower housing 14, each corresponding to one of the upper snap-fit ​​pieces 41. Each upper snap-fit ​​piece 41 has a snap-fit ​​portion 43 on one side, and each lower snap-fit ​​piece 42 has a slot 44 that engages with the snap-fit ​​portion 43. Through the design of the upper snap-fit ​​pieces 41 and lower snap-fit ​​pieces 42 corresponding to each other, and the snap-fit ​​portion 43 engaging with the slot 44, a stable connection between the upper housing 13 and the lower housing 14 is achieved. Compared to screw-based connections, the snap-fit ​​structure offers higher assembly efficiency and requires no additional tools, simplifying the production process. Furthermore, the multiple sets of snap-fits allow for fixation of the housing from multiple positions, enhancing the stability of the housing connection and reducing the risk of loosening due to vibration during use.

[0028] Specifically, the mounting notch 12 includes an upper notch 15 that is rectangular and is respectively provided on the corner of the upper housing 13. The upper notch 15 penetrates two adjacent sides of the upper housing 13 and one side of the upper notch 15 penetrates the end face of the upper housing 13 to form an upper mounting groove. The lower housing 14 has a lower notch 16 at the corner that corresponds to the upper notch 15. The lower notch 16 penetrates the end face of the lower housing 14 to form a lower mounting groove that communicates with the upper mounting groove.

[0029] Meanwhile, the end of the circuit board 11 extends to the bottom of the lower notch 16, and the power cord connector 2 is rectangular and installed inside the lower notch 16 and fixed to the circuit board 11. This achieves precise positioning of the power cord connector 2, avoids misalignment during installation, and ensures the accuracy of subsequent wiring operations.

[0030] Clearly, the upper end of the power cord connector 2 does not extend beyond the upper notch 15, and one side of the power cord connector 2 does not extend beyond the lower mounting groove. Furthermore, one power cord connector 2 has a 210V-240V AC input port 21, while the other power cord connector 2 has a 24V DC output port 21. This design avoids excessive extension of the power cord connector 2, reduces the risk of damage from external impacts, and prevents accidental contact, thus improving safety.

[0031] Combination Figure 1 and Figure 5 As shown, the quick-connect assembly 3 includes several push buttons 31 disposed on the upper end of the power cord connector 2 and located on one side of the wiring hole 21. An elastic connecting piece 32 is provided inside the power cord connector 2 via a fixing assembly 5. The two sides of the elastic connecting piece 32 are respectively connected to the wiring terminal 22 and the power cord. The lower end of the push button 31 contacts the upper end of the elastic connecting piece 32, and a limiting part 33 is provided circumferentially at the lower end of the push button 31. The push button 31 eliminates the need for tools such as screwdrivers during wiring operations; simply pressing it connects the power cord to the wiring terminal 22, simplifying the wiring process and reflecting the design goal of easy wiring. The limiting part 33 restricts the range of motion of the push button 31, preventing it from detaching from the power cord connector 2.

[0032] The fixing component 5 includes a fixing post 51 located below the pressing button 31, a wiring hole 21 located on one side of the fixing post 51, a connecting piece insertion groove 52 on the other side of the fixing post 51, and an inclined portion 53 on the upper end of the fixing post 51 near the wiring hole 21.

[0033] Specifically, one side of the elastic connecting piece 32 has a vertical portion 34 located within the connecting piece insertion slot 52. The vertical portion 34 is connected to the terminal block 22. The upper end of the vertical portion 34 is provided with a pressing portion 35 that contacts the pressing button 31, and the end of the pressing portion 35 away from the vertical portion 34 is provided with an arc-shaped portion 36 located within the wiring hole 21. The vertical portion 34 is inserted into the connecting piece insertion slot 52 and connected to the terminal block 22, ensuring a stable connection with the circuit board 11. The pressing portion 35 contacts the pressing button 31, realizing the transmission logic of pressing operation, elastic piece deformation, and connection / disconnection.

[0034] Combination Figure 3 and Figure 4 As shown, the bottom of the power supply housing 1 is provided with several support blocks 17, the circuit board 11 is set on the upper end of the support blocks 17, and the upper side of the support blocks 17 at both ends of the power supply housing 1 is provided with guide protrusions 18 corresponding to the two ends of the circuit board 11.

[0035] The principle of this embodiment is as follows:

[0036] The power cord connector 2 is electrically connected to the circuit board 11 via internal terminals 22. When a power cord needs to be connected, the end of the power cord is inserted into the wiring hole 21. When the power cord is inserted, it contacts the arc-shaped portion 36 of the elastic connecting piece 32. The arc-shaped portion 36 of the elastic connecting piece 32 is located inside the wiring hole 21. Initially, it maintains a close fit with the inner wall of the wiring hole 21 due to its elasticity. As the power cord is inserted, the arc-shaped portion 36 is compressed and undergoes elastic deformation, bending towards the fixing post 51, and finally making close contact with the power cord. At the same time, the vertical portion 34 of the elastic connecting piece 32 contacts the wiring hole 21. Terminal 22 remains connected, thus enabling circuit conduction between the power cord and circuit board 11. When the power cord needs to be removed, press the button 31 on the power cord connector 2. The lower end of the button 31 contacts the pressing part 35 of the elastic connecting piece 32. After pressing, the pressing part 35 is pushed downward to deform, causing the arc-shaped part 36 to bend further away from the power cord, releasing the clamping force on the power cord. At this time, the power cord can be easily pulled out. After releasing the button 31, the elastic connecting piece 32 returns to its original position due to its elasticity, and the arc-shaped part 36 returns to its initial position in the wiring hole 21, waiting for the next wiring.
