Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electrical cabinets, and specifically relates to an electrical cabinet with a wire end protection function. BACKGROUND

[0002] As a core control unit of a power system, the optimization of wire end protection of an electrical cabinet is crucial to equipment safety. Commonly used electrical cabinets, such as GGD cabinets, mainly distribute incoming current to each branch through a busbar, integrate PLC and relays to realize equipment start-stop and interlocking protection, and are configured with sensors for alarm.

[0003] The prior art document with the file number CN118943897B discloses an electrical cabinet with a wire end protection function. In the electrical cabinet, the support assembly cooperates with a spring and a mechanical structure to make the fixing and adjustment of internal components of the electrical cabinet simpler. In the initial stage, the support assembly may not have a large pre-tightening force, so that the support assembly can be more easily inserted or adjusted to the required position in the initial stage of layout, avoiding installation difficulties caused by excessive pre-tightening force. Once positioned, the pre-tightening force can be increased by adjusting the screw rod to ensure stable fixing of the components.

[0004] The above-mentioned electrical cabinet mainly uses a support assembly to stably install components, and uses an external terminal to connect an external line that originally needs to be connected to the components. Although this can avoid the situation that multiple wires share a connection hole, it inevitably brings additional electrical risks, space occupation, cost overhead, maintenance complexity and potential performance degradation. Moreover, since the ignition point of the electrical cabinet is usually highly concentrated in the wire connection head, the main objective reason is that long-term vibration or thermal expansion and contraction causes the bolts to loosen, resulting in insufficient effective contact area, continuously rising contact resistance, and finally causing short circuit, fire and other accidents.

[0021] Adopting the above scheme: the protection mechanism 5 and the positioning mechanism 6 are provided with multiple groups according to installation requirements. When the transverse protection plates 503 are close to each other, the extrusion trapezoidal extrusion plates 504 are moved, and the longitudinal protection plates 505 on both sides of the trapezoidal extrusion plates 504 are also moved towards the direction of the moving sliding blocks 502, that is, towards the direction of the components 4, so that the periphery of the wiring position is covered and protected.

[0023] As shown in Figures 6 to 8 , the middle part of each of the plurality of waist-shaped bases 509 is fixedly connected with a disc 5010, the side wall of the disc 5010 abuts against the sliding groove plate 5012, the upper and lower sides of the disc 5010 are rotatably connected with a fixed bolt 5011, the fixed bolt 5011 movably penetrates through the sliding groove plate 5012, and is fastened by a nut; the inner cavity of the trapezoidal extrusion plate 504 is fixedly and communicatively connected with a plurality of conduits 508, the conduits 508 extend to the side wall of the sliding groove plate 5012, and the outer side of each of the pair of longitudinal protection plates 505 is fixedly connected with a plurality of beveled fins 506 at equal intervals.

[0024] Adopting the above scheme: the installer holds the component 4 with one hand and rotates the bidirectional threaded rod 501 with the other hand, moves the pair of moving sliding blocks 502 closer to each other through the bidirectional threaded rod 501, and further moves the transverse protection plates 503 on both sides closer to each other. The trapezoidal extrusion plate 504 is extruded by the pair of transverse protection plates 503, and is moved towards the direction of the moving sliding block 502 until the side wall of the component 4 abuts against the mounting plate 3, so that the component 4 can be installed on the mounting plate 3 according to the current position. In the later period, when the device is unfolded, the insulating clamp 507 can also be accurately clamped on the wiring bolt 7.

[0025] As shown in Figure 9 and Figure 10 , the positioning mechanism 6 includes a wave-shaped clamp plate 601 movably penetrating through the middle part of the pair of transverse protection plates 503, and the wave-shaped clamp plate 601 is provided with two pairs, and each pair of wave-shaped clamp plates 601 is elastically connected with each other; the outer side of each of the pair of wave-shaped clamp plates 601 abuts against two pairs of adjusting plates 603, the top of each pair of adjusting plates 603 is commonly slidingly penetrated by a horizontal rod, and the bottom is commonly slidingly penetrated by a double-sided slot rod 604.

[0026] As shown in Figure 10 and Figure 11As shown, the two ends of the double-sided groove rod 604 are fixedly connected to the transverse protective plate 503, and the bottom of the double-sided groove rod 604 is provided with a ratchet groove on both sides; the inner cavity of the adjusting plate 603 is rotatably connected with a pawl 605, the pawl 605 is clamped in the ratchet groove, the side wall of the pawl 605 is elastically connected with the adjusting plate 603, and the middle part is fixedly connected with a push rod 606; the top of the push rod 606 is abutted with a vertical plate 607, the middle part of the vertical plate 607 is fixedly connected with a reset pressing plate 602, and the bottom of the reset pressing plate 602 and the vertical plate 607 is commonly fixedly connected with a high-elastic rubber pad 608.

[0027] By adopting the above scheme: the high-elastic rubber pad 608 is fixedly connected in the inner cavity of the transverse protective plate 503. When the wire needs to be replaced, the reset pressing plate 602 is only pressed, so that the push rod 606 is pressed downward through the vertical plate 607, the pawl 605 is rotated through the push rod 606, the pawl 605 is limited with the double-sided groove rod 604, and the wave-shaped clamping plate 601 and the adjusting plate 603 are synchronously pushed to both sides under the spring pressure in the middle part of the wave-shaped clamping plate 601, so that the next use is convenient, and the reset pressing plate 602 is reset under the elastic force of the high-elastic rubber pad 608. Then the bidirectional screw rod 501 is reversely rotated, the transverse protective plate 503 is driven to move outward, and then the trapezoidal extrusion plate 504 is also moved outward, so that the device is unfolded, and the wire or component 4 is removed and replaced.

[0028] The working principle and use process of the present application are as follows: When the component 4 is installed, the wire head of the wire required is passed from the middle of a pair of wave-shaped clamping plates 601 from bottom to top, and is wound on the outer wall of the connecting bolt 7 in sequence and is fastened, and after the connection is completed, the component 4 is installed. The set screw 5011 is loosened, so that the overall position of the insulating clamp head 507 is adjustable, and the specific position of the connecting bolt 7 on the component 4 is adjusted until the insulating clamp head 507 is clamped with the end groove of the connecting bolt 7. Then the set screw 5011 is tightened to limit the position of the insulating clamp head 507. At this time, the installer holds the component 4 with one hand and rotates the bidirectional screw rod 501 with the other hand, moves the pair of moving blocks 502 to each other through the bidirectional screw rod 501, and drives the two transverse protective plates 503 to move closer to each other. The trapezoidal extrusion plate 504 is extruded by the pair of transverse protective plates 503, moves towards the moving block 502, until the side wall of the component 4 abuts against the mounting plate 3, and the component 4 is installed on the mounting plate 3 according to the current position, so that the device is unfolded when the wire is replaced later, and the insulating clamp head 507 can be accurately clamped on the connecting bolt 7. After installation, the end groove of the connecting bolt 7 is clamped and limited by the insulating clamp head 507 and is tightly abutted, so that even if the device vibrates during operation, it is difficult to rotate the connecting bolt 7 back, so that the abutment between the connecting bolt 7 and the wire joint is always tight, avoiding the increase of resistance caused by the loosening of the joint in the prior art; Further, in the process of the transverse protection plates 503 moving close to each other, the extrusion trapezoidal extrusion plates 504 are also moved, and the longitudinal protection plates 505 on both sides of the trapezoidal extrusion plates 504 are also moved towards the direction of the moving slider 502, i.e. towards the direction of the component 4. Since the longitudinal protection plates 505 are elastically connected with the sliding groove plate 5012, when the insulation clamping head 507 clamps the connection bolt 7, the longitudinal protection plates 505 can abut against the surface of the component 4, and cooperate with the transverse protection plates 503 to cover and protect the connection position from all directions. Not only can dust be prevented, but also when a fire breaks out in other positions, the spread of the fire to the adjacent component 4 can be slowed down. When in normal operation, the heat of the connection position can be conducted out through the inclined edge fins 506 on the outside of the longitudinal protection plates 505, and cooperate with the setting of the temperature sensor 8. When the temperature of the connection position exceeds the preset value, the external cold air is introduced through the conduit 508 for spot cooling. The conduit 508 is provided with a plurality of conduits, and when the external cold air is introduced, one of the blocked conduits 508 can be arbitrarily selected for connection, so as to avoid the situation that the insulation clamping head 507 adjusts the position and blocks part of the conduit 508; When the component 4 is installed, the connected wire is passed through a pair of wave-shaped clamping plates 601 downwards. At this time, the installer can manually pinch the end portion of the push rod 606 on both sides to move it to the center. Under the engagement of the pawl 605 and the double-sided slot rod 604, the pawl 605 can only move unidirectionally towards the center. A pair of adjusting plates 603 can extrude the wave-shaped clamping plates 601 in the middle to move close to each other, until the wave-shaped clamping plates 601 stably clamp the hanging wire. After the installer releases his hand, the position of the wave-shaped clamping plates 601 does not change. In this way, the clamping force can be arbitrarily applied according to the thickness of the wire, so as to ensure that the area below the connection position is also stably positioned, and the safety of the connection position is improved. When the wire needs to be replaced, the reset plate 602 is only pressed, so that the push rod 606 is pressed downwards through the vertical plate 607, the pawl 605 is rotated through the push rod 606, the pawl 605 is released from the limitation of the double-sided slot rod 604, and under the spring pressure in the middle of the wave-shaped clamping plate 601, the wave-shaped clamping plate 601 and the adjusting plate 603 are synchronously pushed to both sides for the next use. The reset plate 602 is reset under the elastic force of the high-elastic rubber pad 608. Then, the bidirectional screw rod 501 is reversely rotated, the transverse protection plates 503 are driven to move outward, and the trapezoidal extrusion plates 504 are also moved outward, so that the device is unfolded, and the wire or the component 4 can be removed and replaced.
