[0037] The following will be combined with the appendix Figures 1 to 12 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0038] This utility model provides an improved power monitoring network equipment interface, including a monitoring network controller 1, a first cable 2 and a second cable 3. One end of the first cable 2 is equipped with a device interface component 4, and the first cable 2 and the second cable 3 are connected through the device interface component 4. The device interface component 4 includes a quick-release locking structure and a protective structure.

[0039] The quick-release locking structure includes a high-precision snap-fit ​​mechanism and an elastic reset element 407. The snap-fit ​​mechanism includes a square snap-fit ​​406 and a square interface 412, which are used to achieve an automatic locking function after the interface is inserted, thereby ensuring the stability of the connection. The square snap-fit ​​406 is installed inside the cylindrical insert 403, and the square interface 412 is installed inside the outer sleeve 405.

[0040] The square interface 412 has a square groove inside, and the bottom of the square buckle 406 has a limiting block 410. The bottom of the groove inside the square interface 412 has a guide groove 413. The guide groove 413 is used to guide the alignment during the insertion process of the interface and prevent mechanical damage caused by misoperation. Its function is to guide the alignment during the insertion process of the interface, form a vibration-resistant mechanical locking structure, and ensure that the interface will not loosen due to external force or vibration during the operation of the power monitoring system, thereby ensuring the continuity of data transmission and system stability.

[0041] The top of the square buckle 406 is connected to the elastic reset element 407. By pressing the elastic reset element 407, the interface can be quickly locked and unlocked, thereby realizing the convenient removal of the interface. The reset element 407 is L-shaped. The bottom end of one end of the elastic reset element 407 is fixed to the square buckle 406, and the other end of the elastic reset element 407 is suspended and tilted upward.

[0042] The top of the elastic reset element 407 is provided with a wedge-shaped wedge protrusion 408, and the top of the groove inside the square interface 412 is provided with a spherical protrusion 415. When the square buckle 406 is inserted into the square interface 412, the elastic reset element 407 is pressed downward, and the wedge protrusion 408 is locked after passing the spherical protrusion 415. At this time, the square buckle 406 is fixed with the square interface 412, thus achieving locking. Pressing the end of the elastic reset element 407 compresses it, and the wedge protrusion 408 is released from the locked state with the spherical protrusion 415, thus achieving unlocking.

[0043] The protective structure includes an outer sleeve 405 and a cylindrical plug 403, with one end of the cylindrical plug 403 connected to the second cable 3 and one end of the outer sleeve 405 connected to the first cable 2.

[0044] The outer sleeve 405 is sleeved on the outside of the cylindrical insert 403. The outer sleeve 405 is installed on the outside of the square interface 412. The inner diameter of the outer sleeve 405 and the outer diameter of the cylindrical insert 403 can be the same, or the inner diameter of the outer sleeve 405 can be 0.5mm to 1.5mm larger than the outer diameter of the cylindrical insert 403. The outer sleeve 405 and the cylindrical insert 403 are slidably connected.

[0045] The outer sleeve 405 and the cylindrical insert 403 have mutually cooperating self-locking protrusions 411 and 7-type grooves 404 on their opposite surfaces. The self-locking protrusions 411 and 7-type grooves 404 are connected and fixed in place. The self-locking protrusions 411 and 7-type grooves 404 adopt a precision fit design, and the tolerance is controlled within a preset range to ensure the connection stability of the protective structure and the reliability after repeated disassembly and assembly, thereby adapting to the harsh operating environment of power monitoring equipment.

[0046] When in use, the cylindrical insert 403 and the outer sleeve 405 are disassembled and moved away from each other. Pressing the end of the elastic reset element 407 on the square buckle 406 inside the cylindrical insert 403 will disassemble the square buckle 406 and the square interface 412, thereby providing physical protection for the interface through the protective structure, isolating dust, moisture and external impact, extending the service life of the interface and improving safety.

[0047] The elastic reset element 407 is provided with limit buckles 409 on both sides. The limit buckles 409 limit the movement trajectory to ensure stability during locking and unlocking, thereby avoiding connection failure caused by component displacement and further ensuring safe connection performance. The limit buckles 409 are L-shaped and the bottom end of the limit buckles 409 is fixed to the square buckle 406. The square buckle 406 has an electrical contact groove 416 embedded inside. The bottom and side wall of the electrical contact groove 416 are set as metal connectors. The metal connectors are connected to the cable core of the second cable. The square buckle 406 and the cylindrical plug 403 are separate. The tail end of the square buckle 406 is directly connected to the cable core of the second cable. The cable core is located inside the second connecting buckle 402 and is movably connected to the second connecting buckle 402. When in use, there is enough space to disassemble the square buckle 406 after the cylindrical plug 403 and the outer sleeve 405 are disassembled and moved away.

[0048] The other end of the elastic reset element 407, away from the top of the square interface 412, has an anti-slip groove.

[0049] A second connecting buckle 402 is installed at the connection between the cylindrical plug 403 and the second cable 3. One end of the second connecting buckle 402 is threaded with a first limiting nut 417. The first limiting nut 417 has a wire hole inside, which is adapted to the size of the second cable 3. One end of the second cable 3 is passed through the wire hole of the first limiting nut 417, and the cable core of the second cable 3 is fixedly connected to the square buckle 406. Then, the first limiting nut 417 is threaded to the second connecting buckle 402, and the square buckle 406 is pulled out of the inner part of the plug 403. Next, the second cable 3 is bonded and fixed to the first limiting nut 417. A first connecting buckle 401 is installed at the connection between the outer sleeve 405 and the first cable 2. One end of the first connecting buckle 401 is threaded with the second limiting nut 418, and the outer wall of the other end is fixed with a limiting ring 419. One end of the first cable 2 is passed through the wire hole of the second limiting nut 418, the wire hole being adapted to the size of the first cable 2. The cable core of the first cable 2 is fixedly connected to the square interface 412. Then, the second limiting nut 418 is threadedly connected to the first connecting buckle 401, and the first cable 2 is bonded and fixed to the second limiting nut 418. Figure 12 As shown, the outer sleeve 405 is fitted onto one end of the first connecting buckle 401, which is fixed to the limiting ring 419. One end of the inner wall of the outer sleeve 405 has an integrally formed edge, the diameter of which is smaller than the outer diameter of the limiting ring 419. The outer diameter of the limiting ring 419 is also smaller than the inner diameter of the outer sleeve 405. The outer sleeve 405 can move on the first connecting buckle 401, and its front end can pass over the limiting ring 419 to connect with the 7-shaped groove 404 of the cylindrical insert 403. The limiting ring 419 prevents the outer sleeve 405 from detaching from one end of the first connecting buckle 401. The second limiting nut 418 restricts the outer sleeve 405 from moving further away from the first connecting buckle 401. The other end of the first connecting buckle 401 is detached. The first connecting buckle 401 wraps around the exposed core surface of the first cable 2 to prevent the core from being exposed to the air. The cylindrical plug 403 is fixed to the second connecting buckle 402. The second connecting buckle 402 wraps around the exposed core surface of the second cable 3 to prevent the core from being exposed to the air. The first connecting buckle 401 and the square interface 412 are fixedly connected. An electrical contact block 414 is installed inside the square interface 412. The electrical contact block 414 has four sets of transmission points, which are respectively connected to the core of the first cable. When the square interface 412 and the square buckle 406 are connected, the transmission speed can be improved.

[0050] When the square buckle 406 is connected to the square interface 412, the square buckle 406 can be pulled out through the inside of the cylindrical insert 403. Then, the limiting block 410 at the bottom of the square buckle 406 is inserted into the guide groove 413 of the square interface 412, and the spherical protrusion 414 is inserted into the electrical contact groove 416. The square buckle 406 and the square interface 412 are then connected. The cylindrical insert 403 is then inserted into the inside of the outer sleeve 405, and the self-locking protrusion 411 on the inner wall of the outer sleeve 405 is aligned with the 7-shaped groove 404 on the outer wall of the cylindrical insert 403. The self-locking protrusion 411 is slid to the end inside the 7-shaped groove 404, and then the outer sleeve 405 is rotated to complete the connection between the cylindrical insert 403 and the outer sleeve 405.

[0051] Working principle: First, the snap-fit ​​mechanism includes a square snap-fit ​​406 and a square interface 412 with a square groove inside. The top of the square snap-fit ​​406 is connected to the elastic reset element 407, and the bottom of the square snap-fit ​​406 is provided with a limiting block 410. The bottom of the groove inside the square interface 412 has a guide groove 413, which guides the alignment of the interface during insertion and prevents mechanical damage caused by misoperation, forming a vibration-resistant mechanical locking structure. This ensures that the interface will not loosen due to external force or vibration during the operation of the power monitoring system, thereby ensuring the continuity of data transmission and system stability. In addition, pressing the elastic reset element 407 allows the interface to be quickly locked and unlocked, thus enabling convenient removal of the interface. Limit buckles 409 are provided on both sides of the elastic reset element 407. The limit buckles 409 limit the movement trajectory, ensuring stability during locking and unlocking, thereby avoiding connection failure caused by component misalignment and further ensuring safe connection performance.

[0052] Then, the top of the elastic reset element 407 is provided with a wedge-shaped wedge protrusion 408, and the top of the groove inside the square interface is provided with a spherical protrusion 415. When the square buckle 406 is inserted into the square interface 412, the elastic reset element 407 is squeezed downward. When the wedge protrusion 408 passes the spherical protrusion 415, the two can be locked together. At this time, the square buckle 406 is fixed to the square interface 412. When it is necessary to remove the two, pressing down on the end of the elastic reset element 407 will remove it.

[0053] Finally, the protective structure includes an outer sleeve 405 and an internally hollow cylindrical insert 403. The opposing surfaces of the outer sleeve 405 and the cylindrical insert 403 are provided with mutually cooperating self-locking protrusions 411 and 7-type grooves 404, which facilitates the connection and fixation of the cylindrical insert 403 and the outer sleeve 405. The self-locking protrusions 411 and the 7-type grooves 404 adopt a precision fit design, and the tolerance is controlled within a preset range to ensure the connection stability of the protective structure and its reliability after repeated disassembly and assembly, thereby adapting to the harsh operating environment of power monitoring equipment. In use, the cylindrical insert 403 and the outer sleeve 405 are disassembled and moved away from each other. Pressing the end of the elastic reset element 407 on the square buckle 406 inside the cylindrical insert 403 will disassemble the square buckle 406 and the square interface 412, thereby providing physical protection for the interface through the protective structure, isolating it from dust, moisture and external impact, extending the service life of the interface and improving safety.

[0054] The design of this utility model aims to improve the secure connection performance and ease of operation of the interface of power monitoring network equipment. The device interface component 4 achieves stable connection of the interface under vibration, impact or harsh environment through the synergistic effect of the automatic locking mechanism of the quick-release locking structure and the physical protection mechanism of the protective structure. At the same time, the one-button press unlocking operation reduces maintenance difficulty and improves operation efficiency. The quick-release locking structure is composed of a high-precision snap-on mechanism and an elastic reset element 407, which is used to achieve automatic locking function after the interface is inserted, thereby ensuring the stability of the connection.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
