Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0027] Reference example Figures 1 to 4 A modular power plug includes an upper housing 1 and a lower housing 2. A plug assembly 3 is provided between the upper housing 1 and the lower housing 2. The plug assembly 3 includes a base 4 and an upper cover 5. The upper cover 5 is detachably connected and fixed to the base 4. A plurality of insert terminals 6 are provided between the base 4 and the upper cover 5. The insert terminals 6 are provided with wiring terminals 7. The lower housing 2 is provided with at least one connecting part 21 and is pressed against the base 4 to connect and fix the base 4 to the lower housing 2.

[0028] By designing the plug assembly 3 as a modular structure and using the connecting part 21 to achieve a fixed connection with the lower housing 2, stable support is provided for the wiring process, improving the convenience and reliability of wiring operations. The modular design facilitates assembly and replacement, enhances the overall structure and maintenance convenience, and the setting of the connecting part 21 effectively restricts the displacement of the plug assembly 3 during the wiring process, reduces external force interference, and improves connection stability.

[0029] By setting a detachable base 4 and a top cover 5, the plug-in terminal 6 and wiring terminal 7 can be quickly replaced, improving maintenance convenience and equipment lifespan. The detachable structure enhances the flexibility of component replacement, adapts to different usage scenarios, and improves the maintainability and economy of the product.

[0030] It is worth mentioning that the base 4 is provided with a fixing hole 41 for the connecting part 21 to pass through, and the upper shell 1 and the lower shell 2 are connected and fixed to each other by fastening screws 72;

[0031] It is worth mentioning that a protrusion 22 is provided on one side of the connecting part 21. The protrusion 22 has a first inclined surface 23 at the entry into the fixing hole 41. As the base 4 slides on the first inclined surface 23, it drives the connecting part 21 to bend towards the center of the fixing hole 41 and store elastic potential energy. When the protrusion 22 enters the fixing hole 41 and is above it, the connecting part 21 releases energy, so that the protrusion 22 is above the base 4, preventing the base 4 from detaching from the lower housing 2, thus fixing the base 4 to the lower housing 2. If the base 4 needs to be disassembled, the upper cover 5 must be removed first. With the help of tools, the protrusion 22 is moved towards the center of the fixing hole 41. Then, the base 4 is pulled upward to detach from the connecting part 21, thereby completing the replacement of the plug assembly 3. This structure realizes a reliable connection and convenient disassembly between the base 4 and the lower housing 2, improving assembly and maintenance efficiency.

[0032] It is worth mentioning that the outer wall of the base 4 is provided with anti-retraction parts 42 on both sides, and the entrance of the anti-retraction parts 42 is provided with a second inclined surface 43. The base 4 is provided with a chamber 44 that independently accommodates the plug-in terminals 6 and the wiring terminals 7. The chamber 44 is provided with wiring holes 45. The chamber 44 increases the electrical performance and safety of adjacent plug-in terminals 6.

[0033] It is worth mentioning that the top cover 5 has ear clips 51 on both sides. The ear clips 51 abut against the anti-retraction part 42. The ear clips 51 are detachable, which makes it easy to replace one of the plug terminals 6 or the wiring terminal 7 individually.

[0034] It is worth mentioning that an insulating sleeve 8 is provided between the base 4 and the upper cover 5. The insulating sleeve 8 has a through groove 81 for the insert terminal 6 to pass through. The insulating sleeve 8 is located near the end face of the insert terminal 6 near the upper housing 1 and the lower housing 2 to prevent the user from accidentally touching the insert terminal 6 during the insertion and removal operation, thereby improving the safety of use.

[0035] It is worth mentioning that the terminal 7 includes a crimping plate 71 and a fastening screw 72. The terminal 7 is provided with a lead-out foot 61, which is located inside the crimping plate 71. The fastening screw 72 is threaded to the crimping plate 71 and abuts against the lead-out foot 61. As the fastening screw 72 is rotated, the crimping plate 71 moves up and down on the lead-out foot 61. After placing the exposed part of the wire on the back of the lead-out foot 61 and inside the crimping plate 71, the fastening screw 72 is tightened. The crimping plate presses the exposed part of the wire onto the lead-out foot 61, thus completing the electrical connection.

[0036] It is worth mentioning that the top cover 5 is provided with an operating hole 52 corresponding to the fastening screw 72.

[0037] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
