Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, in particular to an outdoor power distribution cabinet that is protected from electric shock. Background Art

[0002] Distribution cabinet is a general term for motor control center. Distribution cabinet is used in the occasions where the load is relatively dispersed and there are fewer circuits, as well as in the occasions where the load is concentrated and there are more circuits. They distribute the electric energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 10 The present invention provides a technical solution: an outdoor power distribution cabinet for preventing electric shock, comprising a power distribution cabinet 1, a power-off switch 2 is installed in the power distribution cabinet 1, and further comprising:

[0038] A wiring slot 3 is provided on the power-off switch 2, and a wiring post is provided in the wiring slot 3;

[0039] An extension part 4 is fixed below the power-off switch 2 and corresponds to the wiring slot 3, an insulating strip 5 is installed on the extension part 4, a connection fork 7 is rotatably installed on the top of the insulating strip 5 through a torsion spring, and the torsion spring applies a torsional force away from the terminal to the connection fork 7, and the wire 8 is inserted into the connection fork 7 and extends from the end thereof, and an insulating wrapping layer 6 is provided on the top of the insulating strip 5 away from the terminal;

[0040] The crimping part is arranged in the wiring slot 3, and the crimping part can rotate to press the power fork 7 downward so that the wire 8 extending from the end thereof is pressed on the terminal post to realize electrical connection, and the torsion spring is twisted and accumulates elastic potential energy;

[0041] The locking part locks the pressed crimping part when the power-off switch 2 remains powered on, and releases the locking of the crimping part when the power-off switch 2 is disconnected.

[0042] When the electric shock prevention outdoor power distribution cabinet is in use, when making wiring connections, the electric wire 8 needs to be inserted into the power fork 7 so that it extends from the end, and the insulation skin of the front end of the electric wire 8 is peeled off so that it can be wound around the terminal, and then the power fork 7 is twisted to rotate it toward the terminal, and at the same time, the torsion spring accumulates elastic potential energy. When the power fork 7 is pressed to the terminal position, the exposed wire at the front end of the electric wire 8 is wound around the terminal, and then the power fork 7 is pressed by the crimping part, and the exposed wire wrapped around the terminal is also crimped together, thereby completing the connection process between the electric wire 8 and the terminal, and at the same time, the locking part also locks the crimping part, thereby ensuring that the crimping part and the power fork 7 are always kept in a crimped state;

[0043] When the distribution cabinet is in use and the circuit has excessive current or overload, the power-off switch 2 will automatically cut off the power. The power-off switch 2 can adopt an existing air switch or a fuse switch, which will not be described in detail in this case. When the power-off switch 2 cuts off the power to the circuit, the locking part will contact and lock the crimping part, and then the crimping part will bounce up under the torsional force of the power fork 7, releasing the squeezing of the terminal and the wire 8. At the same time, the power fork 7 will rotate away from the terminal under the action of the torsional force until it hits the insulating wrapping layer 6, and the wire 8 and its exposed conductor are embedded in the insulating wrapping layer 6 under the action of the torsional force, so that the wire 8 can be disconnected from the terminal and the exposed part of the wire 8 can be insulated, so as to avoid the risk of electric shock to the maintenance personnel who perform subsequent maintenance due to the residual current carried by the exposed conductor. Moreover, disconnection from the terminal can also avoid the failure of the power-off switch 2, which will cause the current in the circuit to be in a semi-disconnected state, thereby reducing safety hazards.

[0044] It is worth mentioning that a grounded power connection plate can be added to the insulating wrapping layer 6. After the wire 8 is inserted into the insulating wrapping layer 6, it will contact with it and release the residual current, which can further reduce the risk of electric shock and improve safety performance.

[0045] In one of the more preferred embodiments, an outer ring tube 9 is fixed to the bottom of the wiring groove 3, and an inner ring tube 10 is integrally formed at the center of the outer ring tube 9. The terminal includes an outer sheath tube 11 and a conductive core 12 that are arranged in an inner and outer shell. The outer sheath tube 11 is installed on the inner wall of the inner ring tube 10, and a gasket ring 13 is fixed to the outer wall of the conductive core 12 near the top, and a section of the conductive core 12 located above the gasket ring 13 is set as a winding area, and the bottom end of the conductive core 12 is connected to the circuit through a connecting wire.

[0046] See the terminal for Figure 4 and Figure 8 When the connecting fork 7 rotates to the outer ring tube 9, the fork at its end will be sleeved on the outer periphery of the outer tube 11, and then the stripped bare wire is wound around the winding area above the conductive core 12 above the gasket ring 13, and then the crimping part is pressed down and pressed tightly against the wire 8 with the gasket ring 13 to ensure a stable electrical connection.

[0047] In one of the more preferred embodiments, an implementation of a crimping portion is provided;

[0048] The crimping part includes a crimping frame 19 rotatably mounted on the inner wall of the wiring groove 3. A hollow is provided in the middle of the crimping frame 19, and an outer cover shell 15 is fixed at the hollow position. The outer diameter of the outer cover shell 15 is smaller than the inner diameter of the outer ring tube 9. The outer wall of the outer cover shell 15 is provided with a slot for the connecting fork 7 to pass through. A pressing sheet 23 is integrally formed on the inner wall of the outer cover shell 15. A wire pressing ring 18 is also installed on the inner wall of the pressing sheet 23 through a bracket. The inner diameter of the wire pressing ring 18 is larger than the diameter of the conductive core 12, and the wire pressing ring 18 can be sleeved on the conductive core 12.

[0049] For details, please refer to Figure 4 , Figure 6 and Figure 7 After the connection fork 7 rotates and completes the winding of the wire 8, the crimping frame 19 is rotated to make the outer cover shell 15 rotate into the outer ring tube 9, and the end of the connection fork 7 is pressed by the pressing sheet 23. At the same time, the wire pressing ring 18 in the outer cover shell 15 presses the wound wire 8 to complete the connection process;

[0050] At the same time, after the crimping frame 19 rotates to press the power connection fork 7, the locking part locks it.

[0051] In one of the more preferred embodiments, an implementation of a locking portion is provided;

[0052] The locking portion includes a slide groove opened at the top of the extension portion 4, and a slidable electric control slider 26 is installed in the slide groove. The electric control slider 26 is electrically connected to the power-off switch 2, and the contact surfaces of the crimping frame 19 and the electric control slider 26 are both embedded with magnets 27.

[0053] For details, please refer to Figure 6 and Fig.10 When the crimping frame 19 is crimped, the magnet 27 embedded at the end thereof will contact and attract the magnet 27 at the top of the electric control slider 26, thereby completing the adsorption and fixation of the crimping frame 19;

[0054] When the power-off switch 2 is disconnected, it will control the electric-controlled slider 26 to slide through an electrical signal so that the magnet 27 on it and the magnet 27 at the bottom of the crimping frame 19 are offset from each other, thereby releasing the adsorption and fixing effect on the crimping frame 19, thereby achieving the purpose of unlocking the crimping frame 19 and completing the subsequent wire 8 disengagement process.

[0055] It is worth mentioning that in the locked state, the force required to move the two magnets 27 away from each other is greater, so the locking effect is better. When unlocking, the two magnets 27 are staggered from each other, which will cause the like poles of the magnets 27 to approach each other, thereby producing a repulsive effect. Therefore, the staggered manner makes it easier to separate the two, which is more conducive to unlocking them.

[0056] In one of the more preferred embodiments, an implementation method for wrapping and isolating the terminal post is provided;

[0057] Two partitions 20 are provided near the top of the outer cover shell 15, and the two partitions 20 divide the space above the inner part of the outer cover shell 15 into two sealed cavities, and the two sealed cavities are respectively filled with base glue and curing agent, which can form an elastomer or a hardened solid when mixed. The top of the outer cover shell 15 is set as an elastic arc surface layer, and a puncture needle 21 is fixed to the inner wall.

[0058] For details, please refer to Figure 5 As can be seen from the previous content, when the crimping frame 19 is unlocked, the power fork 7 will drive the crimping frame 19 to rotate while rotating, similar to the form after the mousetrap is triggered, and then the crimping frame 19 will rotate under the action of the power fork 7, and the elastic arc surface layer on the top will hit the inner wall of the wiring groove 3 and deform, so that the puncture needle 21 will pierce the two partitions 20, and the elastic arc surface layer will reset in the process of driving the crimping frame 19 to rebound, so that the two sealed cavities are connected and the outer cover shell 15 is covered on the outer ring tube 9 again, so that the base glue and curing agent in the two sealed cavities flow downward through the through hole pierced by the puncture needle 21, and the two will form an elastomer or a solid formed after hardening after the flow and mixing, and the conductive core 12 below will be coated to isolate it, thereby achieving a protective effect;

[0059] Furthermore, the deformation of the elastic curved surface layer when it is impacted will cause a certain amount of compression to its internal space, which can help the base glue and curing agent in the two sealing cavities to be squeezed downward for mixing;

[0060] The base glue and curing agent may be silicone potting glue or epoxy resin AB glue, and a mixture of the two can form an insulating material to insulate the conductive core 12 to further reduce the risk of electric shock.

[0061] In this way, by insulating the terminal position and the exposed portion of the wire 8, the safety performance is further improved and the risk of electric shock is reduced.

[0062] In one of the more preferred embodiments, a spring 17 is installed between the outer cover shell 15 and the inner bottom of the outer ring tube 9 , and a torsion spring is installed between the crimping frame 19 and the inner wall of the wiring groove 3 .

[0063] The setting of the spring 17 can increase the force of the crimping frame 19 to rotate and bounce after being unlocked, thereby increasing the impact force between the outer cover shell 15 and the inner wall of the wiring slot 3, thereby ensuring that the puncture needle 21 can penetrate the two partitions 20, and when the crimping frame 19 bounces up, the spring 17 will also pop out from the outer ring tube 9, so that the crimping frame 19 can cover the terminal more deeply after impact and rebound, which can improve the covering effect of the insulating material;

[0064] The torsion spring can exert a certain torsion force to ensure that the outer cover shell 15 can cover the terminal.

[0065] In one of the more preferred embodiments, an implementation method is provided that can improve the degree of compression of the wire 8 to ensure the stability of the electrical connection.

[0066] The side wall of the inner ring tube 10 is provided with a sliding groove 24 that is set through, and a sliding block 14 is slidably installed in the sliding groove 24. The middle part of the sliding block 14 is set as a hollow and inclined inclined portion 25. The outer tube 11 is slidably installed on the inner wall of the inner ring tube 10, and the outer wall of the outer tube 11 is provided with an embedding groove in the same direction as the inclined portion 25. The inclined portion 25 can slide in the embedding groove. Wedge blocks 16 are fixed to the inner walls on both sides of the outer cover shell 15, and the inclined surfaces on the opposite surfaces of the two wedge blocks 16 are in the same direction. The outer walls on both sides of the sliding block 14 are also provided with inclined surfaces that are compatible with the wedge blocks 16.

[0067] See also Figure 4 and Figure 8 , 9When the outer cover shell 15 is pressed down and the electric fork 7 is pressed by the pressing piece 23, the wedge blocks 16 at the bottom of both sides thereof will contact the inclined surface of the outer wall of the sliding block 14 and move to one side against the sliding block 14 while the outer cover shell 15 moves down. Due to the sliding fit between the inclined portion 25 and the groove embedded in the outer wall of the outer package tube 11, the outer package tube 11 will move upward, thereby moving the internal conductive core 12 and the gasket ring 13 upward. In this way, the upward movement of the gasket ring 13 and the downward movement of the wire pressing ring 18 in the outer cover shell 15 can make the wire wound on the conductive core 12 more tightly crimped and the electrical connection more stable.

[0068] In one of the more preferred embodiments, a guide ring 22 is fixed above the wire pressing ring 18, and the top of the guide ring 22 is designed to be an open cone shape.

[0069] See also Figure 5 The guide ring 22 can guide the base glue and curing agent flowing down, so that they can flow down from the gap between the conductive core 12 and the wire pressing ring 18 and wrap around the conductive core 12 to form an insulating layer.

[0070] In one of the more preferred embodiments, the opening portion of the outer ring tube 9 is configured as a flared portion, and the outer cover shell 15 can be rotated in or out.

[0071] Since the outer cover shell 15 will have a certain deviation compared to the straight up and down as the crimping frame 19 rotates, the opening part of the outer ring tube 9 is set as a flared part. Figure 8 This can avoid affecting the moving trajectory of the outer cover shell 15 and avoiding interfering with its travel.

[0072] In one of the more preferred embodiments, the end of the crimping frame 19 is set to be a plane, and when the crimping frame 19 is in a clamped state, the adsorption surfaces between the two magnets 27 embedded on the opposite surfaces of the crimping frame 19 and the electric control slider 26 are both in a horizontal state.

[0073] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0074] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
