[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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.

[0053] Reference Figures 1 to 7 As shown, this embodiment provides an ADMU quick-plug structure, which includes an outer cover 100, a first terminal block 200, a digitization unit module 300, and a locking module 400.

[0054] Specifically, the first terminal block 200 is located inside the outer cover 100; the digital unit module 300 is detachably inserted into the outer cover 100, and the digital unit module 300 is electrically connected to the first terminal block 200; the locking module 400 is located on the digital unit module 300 and can be adapted to the outer cover 100 to lock and unlock the digital unit module 300.

[0055] When the digital unit module 300 needs to be replaced, firstly, the digital unit module 300 is unlocked via the locking module 400. Then, the digital unit module 300 is pulled out from the outer casing 100 for replacement. When the newly replaced digital unit module 300 is inserted into the outer casing 100 and electrically connected to the first terminal 200, the locking module 400 locks the digital unit module 300 inside the outer casing 100, preventing it from being pulled out. This ensures a stable and reliable electrical connection between the digital unit module 300 and the first terminal 200, facilitating the disassembly and replacement of the digital unit module 300. Furthermore, the outer casing 100 provides excellent protection for the digital unit module 300, reducing the probability of damage caused by external particles such as dust and moisture.

[0056] For example, the locking module 400 engages with the outer cover 100, thereby locking the digitizing unit module 300 inside the outer cover 100, and the digitizing unit module 300 maintains an electrical connection with the first terminal 200. For example, when the locking module 400 is separated from the outer cover 100, the digitizing unit module 300 can detach from the outer cover 100.

[0057] When the digital unit module 300 needs to be replaced, firstly, the locking module 400 is separated from the outer cover 100. Then, the digital unit module 300 is pulled out from the outer cover 100 for replacement. When the newly replaced digital unit module 300 is inserted into the outer cover 100 and electrically connected to the first terminal 200, the locking module 400 is snapped into the outer cover 100 to lock the digital unit module 300 inside the outer cover 100, preventing the digital unit module 300 from coming out of the outer cover 100. This ensures a stable and reliable electrical connection between the digital unit module 300 and the first terminal 200, facilitating the disassembly and replacement of the digital unit module 300.

[0058] For example, the first terminal block 200 is plugged into the digital unit module 300.

[0059] For example, the outer cover 100 may be in the shape of a cuboid, and the digital unit module 300 is inserted into the outer cover 100 along the length direction of the outer cover 100.

[0060] In this embodiment, reference is made to Figures 1 to 5 As shown, the outer cover 100 is provided with a limiting hole 101. The locking module 400 includes a locking tongue 410, an elastic element 420, and an unlocking element 430. The locking tongue 410 is disposed on the digital unit module 300, and the locking tongue 410 slides relative to the digital unit module 300 to have a first position and a second position. The elastic element 420 is connected to the locking tongue 410. The elastic element 420 can drive the locking tongue 410 to move to the first position, and the locking tongue 410 is inserted into the limiting hole 101 at the first position to achieve a locking connection between the locking module 400 and the outer cover 100. The unlocking element 430 can abut against the locking tongue 410 and push the locking tongue 410 to the second position, and the locking tongue 410 disengages from the limiting hole 101 at the second position to achieve separation between the locking module 400 and the outer cover 100.

[0061] When the digital unit module 300 needs to be replaced, firstly, the locking tongue 410 is pushed from the first position to the second position by the unlocking member 430 so that the locking tongue 410 disengages from the limiting hole 101; then, the digital unit module 300 is pulled out from the outer cover 100 for replacement. When the newly replaced digital unit module 300 is inserted into the outer cover 100 and electrically connected to the first terminal 200, the locking tongue 410 is reset to the first position and inserted into the limiting hole 101 under the action of the elastic member 420, so as to prevent the digital unit module 300 from exiting out of the outer cover 100, thereby preventing the digital unit module 300 from separating from the first terminal 200. This is stable and reliable, and facilitates the disassembly and replacement of the digital unit module 300.

[0062] In one feasible embodiment, the outer cover 100 is provided with a locking cover 900, which covers the outer end of the limiting hole 101. The locking cover 900 is provided with a relief groove. The locking tongue 410 is inserted into the limiting hole 101 and the relief groove in the first position. While protecting the locking tongue 410, it can prevent external particles from entering the outer cover 100 through the limiting hole 101.

[0063] For example, a sealing gasket (not shown) is sandwiched between the lock cover 900 and the outer cover 100 to form a good seal.

[0064] For example, the lock cover 900 and the outer cover 100 can be fastened together by lock cover fasteners 630. There are at least two lock cover fasteners 630.

[0065] In this embodiment, reference is made to Figure 2 , Figure 4 and Figure 5 As shown, the locking module 400 also includes a locking seat 440 disposed in the digital unit module 300. The locking seat 440 is provided with a sliding groove 441. The locking tongue 410 is slidably disposed in the sliding groove 441, and the elastic element 420 is disposed in the sliding groove 441 and abuts against the locking tongue 410, which facilitates the positioning and assembly of the locking tongue 410 and the elastic element 420.

[0066] For example, the slide groove 441 has a rectangular cross-section, and both long side walls of the slide groove 441 are provided with arc-shaped grooves 442 for accommodating the elastic member 420.

[0067] In this embodiment, reference continues to be made to... Figure 2 , Figure 6 and Figure 7 As shown, the digital unit module 300 includes an inner cover 310, and a locking tongue 410, an elastic element 420, and a locking seat 440 are all located inside the inner cover 310.

[0068] In one feasible embodiment, the inner cover 310 is provided with a first clearance hole 3111, and the locking tongue 410 includes a sliding part 411 and a locking part 412. A stepped surface 413 is formed between the sliding part 411 and the locking part 412. The sliding part 411 is slidably inserted into the sliding groove 441. When the locking tongue 410 is in the first position, the locking part 412 is inserted into the limiting hole 101, and the stepped surface 413 abuts against the inner cover 310 to form a limit and prevent the locking tongue 410 from disengaging from the inner cover 310.

[0069] For example, the locking seat 440 and the inner cover 310 can be fastened together by locking seat fasteners 640. At least two locking seat fasteners 640 are provided.

[0070] For example, the locking part 412 is provided with a first chamfered surface 414 at one end away from the sliding part 411, and the first chamfered surface 414 faces the first plug-in terminal to facilitate the locking part 412 sliding into the outer cover 100.

[0071] In one feasible embodiment, the inner cover 310 is provided with a second clearance hole 3131, and the locking seat 440 is provided with a blind hole 443 communicating with the slide groove 441. The end face of the locking seat 440 with the slide groove 441 and the end face with the blind hole 443 both abut against the inner cover 310, which helps to reduce the risk of external particles entering the inner cover 310 through the slide groove 441 and the blind hole 443. The locking tongue 410 is provided with an unlocking hole 415, and an unlocking member 430 is sequentially inserted through the second clearance hole 3131, the blind hole 443, and the unlocking hole 415. The unlocking member 430 can push the locking tongue 410 to a second position by pushing against the wall of the unlocking hole 415, facilitating the locking tongue 410 to disengage from the limiting hole 101. When the locking tongue 410 is in the first position, the axis of the blind hole 443 and the axis of the unlocking hole 415 are misaligned. When the locking tongue 410 is in the second position, the axis of the blind hole 443 and the axis of the unlocking hole 415 can coincide.

[0072] For example, the combined shape between the groove 441 and the blind hole 443 is cross-shaped.

[0073] For example, the unlocking element 430 is rod-shaped.

[0074] For example, the first end of the unlocking member 430 is provided with a second chamfered surface 431 to form a clearance, so that the first end of the unlocking member 430 is adapted to pass through the unlocking hole 415 and push the latch 410 to the second position.

[0075] For example, the first end of the unlocking element 430 can be threaded into the blind hole 443, and the digital unit module 300 is connected to the unlocking element 430 to prevent the unlocking element 430 from being lost.

[0076] For example, the second end of the unlocking member 430 is provided with a protrusion 432 to facilitate hand operation. The protrusion 432 may be annular.

[0077] In this embodiment, reference is made to Figure 2 and Figure 6 As shown, the digital unit module 300 includes not only an inner cover 310, but also a module main board 320 disposed inside the inner cover 310, and a second terminal block 330 electrically connected to the module main board 320. The second terminal block 330 is plugged into the first terminal block 200.

[0078] In one feasible embodiment, the inner cover 310 includes a cover body 311, a top cover 312 and a bottom cover 313, with the top cover 312 covering the top opening of the cover body 311 and the bottom cover 313 covering the bottom opening of the cover body 311.

[0079] For example, the material of the cover body 311 can be a metal material, such as aluminum alloy.

[0080] For example, the top cover 312 may be made of plastic.

[0081] For example, the bottom cover 313 may be made of aluminum alloy or plastic.

[0082] For example, the first clearance hole 3111 is provided on the periphery of the cover body 311, and the end face of the locking seat 440 with the groove 441 abuts against the cover body 311.

[0083] For example, the cover body 311 has slots 3112 on both sides along its width direction, and the module motherboard 320 is inserted into the slots 3112, which facilitates assembly and positioning.

[0084] For example, the second clearance hole 3131 is provided on the bottom cover 313, and the end face of the locking seat 440 with the blind hole 443 abuts against the bottom cover 313.

[0085] For example, the top cover 312 is provided with a plug portion 3121, and the plug portion 3121 is provided with a through hole (not shown). The second terminal 330 is exposed through the through hole so that the second terminal 330 is suitable for plugging into the first terminal 200.

[0086] For example, the top cover 312 and the cover body 311 can be fastened together by top cover fasteners 650. There are multiple top cover fasteners 650, such as three, four or six.

[0087] For example, the bottom cover 313 and the cover body 311 can be fastened together by bottom cover fasteners 660. There are multiple bottom cover fasteners 660, such as three, four or six.

[0088] In this embodiment, reference is made to Figure 1 and Figure 3 As shown, the outer casing 100 is provided with a terminal hole 102, and the first wiring terminal 200 is exposed in the terminal hole 102 so that the first wiring terminal 200 is suitable for electrical connection with external products. For example, the digital unit module 300 is electrically connected to the circuit breaker of the primary equipment through the first wiring terminal 200.

[0089] In one feasible implementation, the ADMU quick-plug structure further includes a face shield frame 510, which can fill the gap between the outer cover 100 and the external product, and the ADMU quick-plug structure and the external product form a channel at the face shield frame 510 to protect the electrical connection between the ADMU quick-plug structure and the external product.

[0090] Exemplarily, the ADMU quick-plug structure further includes a first sealing gasket 520 and a second sealing gasket 530. The first sealing gasket 520 is sandwiched between the outer cover 100 and the face mask frame 510, and the second sealing gasket 530 is located on the side of the face mask frame 510 away from the first sealing gasket 520. The second sealing gasket 530 can form a seal with external products. It is understood that the design of the first sealing gasket 520 and the second sealing gasket 530 provides a good sealing effect for the channel formed between the ADMU quick-plug structure and the external products at the face mask frame 510, which is beneficial for protecting the electrical connection between the ADMU quick-plug structure and the external products.

[0091] For example, both ends of the mask frame 510 are provided with recesses (not shown), the first sealing gasket 520 is located in one of the two recesses, and the second sealing gasket 530 is located in the other of the two recesses to achieve positioning assembly.

[0092] Exemplarily, the first sealing gasket 520 can be fastened to the face mask frame 510 via a first screw connector 610. Multiple first screw connectors 610 are provided, such as three, four, or six. The first screw connectors 610 can pass through the outer cover 100 and the first sealing gasket 520 and be fastened to the face mask frame 510, thus enabling connection between the outer cover 100, the face mask frame 510, and the first sealing gasket 520 for easy assembly. Of course, the first sealing gasket 520 can also be fixed to the face mask frame 510 by adhesive (e.g., waterproof adhesive) or other methods; this embodiment is not limited to these methods.

[0093] Exemplarily, the second sealing gasket 530 can be fastened to the face mask frame 510 by a second screw (not shown). Multiple second screws are provided, for example, three, four, or six. Of course, the second sealing gasket 530 can also be fixed to the face mask frame 510 by adhesive (e.g., waterproof adhesive) or other means; this embodiment is not limited to this method.

[0094] In this embodiment, reference is made to Figure 1 , Figure 3 and Figure 6 As shown, the ADMU quick-plug structure also includes a terminal block 700, which is located inside the outer cover 100. The terminal block 700 is provided with a first wiring terminal 200, which facilitates the assembly of the first wiring terminal 200 inside the outer cover 100.

[0095] For example, the terminal block 700 may be made of plastic.

[0096] In one feasible implementation, the ADMU quick-plug structure further includes a first fastener 620. The first fastener 620 passes through the terminal block 700 and the outer cover 100 and is fastened to the faceplate frame 510. That is, the first fastener 620 enables the connection between the terminal block 700, the outer cover 100, and the faceplate frame 510, facilitating assembly. It is understood that the first terminal 200 is fixed inside the outer cover 100 by the terminal block 700 with a threaded fastener, which facilitates disassembly and assembly and ensures a stable and reliable connection.

[0097] For example, at least two first fasteners 620 are provided, for example, two are spaced apart along the width direction of the outer cover 100.

[0098] In one feasible implementation, the first terminal block 200 includes a first terminal piece 210, an electrical connection plate 220, and a second terminal piece 230 that are electrically connected in sequence. The first terminal piece 210 is electrically connected to the digital unit module 300, and the second terminal piece 230 is used for electrical connection with external products.

[0099] For example, the first terminal piece 210 is plugged into the digital unit module 300, for instance, the first terminal piece 210 is plugged into the second wiring terminal 330.

[0100] For example, the second terminal 230 is plugged into an external product.

[0101] Exemplarily, at least a portion of the second terminal member 230 is located within the face mask frame 510 for easy connection to external products. Exemplarily, the second terminal member 230 protrudes from the face mask frame 510 for easy connection to external products.

[0102] In one possible implementation, the terminal block 700 is provided with a mounting channel 701, and at least a portion of the structure of the first terminal 200 is disposed within the mounting channel 701 to protect the first terminal 200.

[0103] For example, the first end of the mounting channel 701 faces the terminal hole 102. It is understood that the digitization unit module 300 is electrically connected to the first terminal 200 at the second end of the mounting channel 701.

[0104] For example, the first terminal piece 210 is located within the mounting channel 701.

[0105] In one feasible implementation, a sealing sleeve 800 is provided in the installation channel 701, and the digital unit module 300 can be inserted into the sealing sleeve 800 and electrically connected to the first terminal 200 (e.g., the first terminal piece 210 of the first terminal 200) to form a seal, which helps to reduce the risk of external particles coming into contact with the first terminal 200.

[0106] For example, the first terminal piece 210 is located within the sealing sleeve 800.

[0107] For example, the plug portion 3121 passes through the second end of the mounting channel 701 and extends between the sealing sleeve 800 and the first terminal 210 to form a seal, which helps to reduce the risk of external particles coming into contact with the first terminal 210 and the second terminal 330.

[0108] In one possible implementation, the terminal block 700 includes a block body 710 and a block cover 720 disposed on the block body 710, with an installation channel 701 formed between the block body 710 and the block cover 720.

[0109] For example, the seat body 710 is fastened to the outer cover 100 by a first fastener 620.

[0110] For example, at least a portion of the electrical connection plate 220 is located within the mounting channel 701 and sandwiched between the sealing sleeve 800 and the seat cover 720, which helps to reduce the risk of external particles reaching the second end of the mounting channel 701 through the mounting channel 701, thereby protecting the electrical connection between the digital unit module 300 and the first terminal block 200.

[0111] For example, the seat body 710 has an installation groove 702 in the installation channel 701, and the sealing sleeve 800 is disposed in the installation groove 702.

[0112] For example, along the insertion / removal direction of the digital unit module 300 relative to the outer cover 100, a cover 720 is disposed on the end of the base body 710 away from the digital unit module 300, and a notch 703 is provided on the periphery of the end of the base body 710 away from the digital unit module 300. The first end of the mounting channel 701 is formed at the notch 703, and the electrical connection plate 220 passes through the notch 703. It is understood that the cover 720, together with the electrical connection plate 220 and the sealing sleeve 800, can form a seal on the notch 703.

[0113] Exemplarily, the seat body 710 and the seat cover 720 can be fastened together by a second fastener (not shown). Exemplarily, there are multiple second fasteners, such as three, four, or six. In this embodiment, the second fasteners may also pass through the first terminal member 210 and the electrical connection plate 220 to press the first terminal member 210 and the electrical connection plate 220 between the seat body 710 and the seat cover 720.

[0114] In this embodiment, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the outer cover 100 includes a first housing 110 and a second housing 120. An opening groove 103 is formed between the first housing 110 and the second housing 120. A first wiring terminal 200 is disposed in the opening groove 103, and the digital unit module 300 is inserted into the opening groove 103. The second housing 120 is provided with a limiting hole 101, which communicates with the opening groove 103. The extending direction of the limiting hole 101 forms an angle (e.g., a 90° angle) with the opening direction of the opening groove 103, so that the locking tongue 410 is inserted into the limiting hole 101 in the first position, preventing the digital unit module 300 from exiting the outer cover 100. It can be understood that the digital unit module 300 is inserted into the outer cover 100 through the opening of the opening groove 103.

[0115] For example, the first housing 110 and the second housing 120 can be made of metal, such as aluminum alloy.

[0116] For example, the opening of the slot 103 can be located at the bottom of the outer cover 100 along its length, which helps to reduce the risk of external particles entering through the opening of the slot 103.

[0117] In one feasible embodiment, the first housing 110 includes a first base plate 111 and a first surrounding plate 112 bent at the edge of the first base plate 111. The side of the first surrounding plate 112 away from the first base plate 111 has a folded edge 113. The second housing 120 is located between the first base plate 111, the first surrounding plate 112, and the folded edge 113. The projection of the folded edge 113 of the first surrounding plate 112 along the thickness direction of the outer cover 100 is located on the first base plate 111. The second housing 120 has a terminal hole 102. A face mask frame 510 is disposed on the second housing 120 and surrounds the terminal hole 102. A sealing groove 511 is provided on the outer periphery of the face mask frame 510. The folded edge 113 is slidably inserted into the sealing groove 511 to achieve a positioning connection, facilitating assembly and reducing the risk of external particles entering the opening groove 103 through the gap between the outer periphery of the face mask frame 510 and the folded edge 113 of the first surrounding plate 112.

[0118] For example, the sealing groove 511 may be U-shaped.

[0119] For example, the ADMU quick-plug structure also includes a sealing strip (not shown), which is disposed in the sealing groove 511. The folded edge 113 is slidably inserted into the sealing groove 511 and abuts against the sealing strip, which helps to reduce the risk of external particles entering the opening groove 103 through the gap between the outer periphery of the mask frame 510 and the folded edge 113 of the first enclosure 112.

[0120] For example, the sealing strip can be U-shaped.

[0121] Exemplarily, the second housing 120 includes a second base plate 121 and a second surrounding plate 122 bent along the edge of the second base plate 121. Terminal holes 102 and limiting holes 101 are both located on the second base plate 121, and the terminal seat 700 is fastened to the second base plate 121, which helps ensure the positional accuracy between the locking tongue 410 and the limiting hole 101. It is understood that both the second surrounding plate 122 and the second base plate 121 are located inside the first housing 110, and an opening groove 103 is formed between the first base plate 111 and the second base plate 121. Exemplarily, both the first surrounding plate 112 and the second surrounding plate 122 can be U-shaped.

[0122] For example, the first enclosure 112 is bent to provide a first connecting ear 114, and the second enclosure 122 is bent to provide a second connecting ear 123. The ADMU quick-plug structure also includes a third fastener (not shown) and a screw sleeve (not shown). The third fastener passes through the first connecting ear 114 and the second connecting ear 123 and is fastened to the screw sleeve. It is inserted into the sealing groove 511 with the folded edge 113 to realize the positioning assembly between the first housing 110 and the second housing 120.

[0123] For example, both the first connecting ear 114 and the second connecting ear 123 have holes for the third fastener to pass through, and at least one of the first connecting ear 114 and the second connecting ear 123 has a waist-shaped hole, which is beneficial for the folded edge 113 of the first enclosure plate 112 to be pressed against the sealing strip.

[0124] For example, the first housing 110 is provided with first connecting ears 114 on both sides along the width direction, and the first connecting ears 114, the second connecting ears 123, the third fastener and the screw sleeve are provided in a one-to-one correspondence.
