Description

Technical Field

[0001] This utility model relates to the field of wiring structure technology, and in particular to a drawer-type wiring structure and an energy meter. Background Technology

[0002] Drawer-type wiring structure is a modular electrical connection system, mainly used in low-voltage distribution cabinets (such as GCK, GCS, MNS models) and switchgear. Its core feature is that flexible power distribution and maintenance are achieved through removable functional units.

[0003] In existing drawer-type junction boxes, electrical components such as circuit breakers and contactors are installed inside the box. Then, multiple electrical components are connected to the terminals on the box via wires. The box is then inserted into the distribution cabinet, and the terminals are inserted into the ports on the distribution cabinet to achieve electrical connection between the electrical components and the distribution cabinet. At the same time, the electricity meter on the box displays the connection status and usage data of the electrical components.

[0004] However, because the box is used in a pull-out manner, the electrical components are hidden inside the box, and the outside cannot see the operating status of the electrical components. This may cause the electrical components to be unable to cut off the power supply to the wires in time when a short circuit or overload occurs, resulting in the electrical components being in a short circuit or overload state for a long time. This can cause the electrical components to heat up and spontaneously combust, affecting the safety of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a drawer-type wiring structure and an energy meter, which aims to solve the problems in the prior art.

[0006] This utility model is implemented as follows: a drawer-type wiring structure includes: a box body, which is placed inside a distribution cabinet for carrying and installing electrical components; a wiring terminal, which is disposed on the box body, wherein the wires connecting the electrical components are electrically connected to the distribution cabinet through the wiring terminal; and a blocking device, which is disposed inside the box body, wherein the blocking device divides the wires connecting the electrical components into two segments and quickly disconnects the power supply of the wires in the event of a short circuit or overload.

[0007] Preferably, the blocking device includes: a shaft frame, which is detachably installed inside the housing via an adjusting assembly, wherein an electric telescopic rod is provided on the shaft frame; a partition plate, which is fixedly connected to the moving end of the electric telescopic rod, wherein the partition plate is an insulating rubber plate, and a temperature sensor is provided on one side of the partition plate; two round hole rods, which are symmetrically sleeved on the shaft frame, and a tension spring is fixedly connected between each of the two round hole rods and the shaft frame, wherein the two ends of the tension spring are fixedly connected to the round hole rod and the shaft frame respectively; and a plurality of terminals, which are evenly fixedly connected to the two round hole rods, wherein a copper plate is fixedly connected to the adjacent ends of the terminals on both sides.

[0008] The aforementioned components achieve the following effect: By setting up a blocking device, the two round-hole rods are first pulled closer together by the extension and retraction of the tension spring, simultaneously moving multiple terminals and copper plates. When the tension spring is fully compressed, the copper plates on both sides are brought into contact with each other. At this point, the wires connecting the electrical components and terminals are divided into two sections and connected to the terminals on both sides. The electrical connection between the electrical components and terminals is completed using the terminals and copper plates on both sides. Simultaneously, the temperature sensor uses a detection module to monitor the temperature of the electrical components inside the housing. When the electrical components generate high temperatures due to short circuits or overloads, the detection module immediately inputs the detected temperature information into the system. In the electrical control unit, the operation of the electric telescopic rod is controlled, causing the electric telescopic rod to move the partition plate closer to the copper plate. During the movement, the partition plate squeezes the copper plates on both sides, causing them to separate and disconnecting the electrical connection between the wires on both sides. This cuts off the power supply to the electrical components, thus completing the overload protection of the electrical components. This reduces the possibility that the electrical components cannot immediately cut off the power supply when a short circuit or overload occurs, resulting in the electrical components being in a short circuit or overload state for a long time, causing the electrical components to overheat and spontaneously combust. This improves the safety of the electrical components.

[0009] Preferably, a rubber ring is fixed to one side of the shaft bracket, wherein the position of the rubber ring corresponds to that of the circular hole rod.

[0010] The effect achieved by the above-mentioned components is that by setting the rubber ring, the round hole rod can be intercepted during the movement, reducing the collision and wear between the round hole rod and the shaft frame during the movement, thus affecting the service life.

[0011] Preferably, a liquid storage box is fixedly connected to one side of the circular hole rod, wherein the liquid storage box is provided with a feed pipe, wherein a sealing cap is fitted on the feed pipe, and wherein a hole communicating with the inner wall of the circular hole rod is opened inside the liquid storage box.

[0012] The effect achieved by the above components is as follows: by setting up a liquid storage box, personnel can put glue into the liquid storage box, so that the glue flows into the gap between the round hole rod and the shaft frame through the hole to bond and fix the round hole rod, increasing the stability of the round hole rod and reducing the shaking of the round hole rod due to the elastic expansion and contraction of the tension spring during use, which affects the stability of the electrical connection.

[0013] Preferably, the circular hole rod has a threaded groove on the side near the terminal block, wherein a protective cover is threaded onto the inner wall of the threaded groove, and the protective cover is fitted onto the surface of the terminal block.

[0014] The effect achieved by the above-mentioned components is as follows: by setting up a protective cover, the wire is first inserted through the hole on the protective cover, and then the end of the wire inserted inside the protective cover is connected to the terminal. At this time, the protective cover is manually rotated, so that the protective cover moves left and right along the inside of the threaded groove. When the protective cover is completely rotated into the inside of the threaded groove, the protective cover completely encloses the terminal and provides protection for the internal terminal and wire core, reducing the possibility of damage to the terminal and wire core from external objects during maintenance and use, thus affecting their normal use.

[0015] Preferably, multiple rubber blocks are fixed to the inner wall of the holes in the protective cover, wherein the rubber blocks are arranged in a circular pattern.

[0016] The effect achieved by the above-mentioned components is that by setting rubber blocks, the surface of the inserted wire can be squeezed and assisted in limiting its movement, reducing the gap between the wire and the inner wall of the hole, which would cause the wire to sway left and right, affecting the stability of the connection with the terminal.

[0017] Preferably, the adjustment component includes: a perforated frame, which is fixedly connected to the inner wall of the box, wherein the inner wall of the perforated frame is threaded with bolts, and the shaft bracket is placed inside the perforated frame and fixed by bolts; and a wear-resistant plate, which is fixedly connected to the side of the perforated frame near the box, wherein the wear-resistant plate is made of high manganese steel.

[0018] The effects achieved by the above components are as follows: By setting the adjustment component, the shaft bracket is first manually moved to the position inside the insertion hole frame. When the shaft bracket moves to the position where the inner wall coincides with the inner wall of any hole on the hole frame, the bolt is manually screwed into the hole frame and the shaft bracket to fix the position of the shaft bracket. This completes the assembly and fixation between the shaft bracket and the box and the height adjustment. At the same time, the shaft bracket can be freely disassembled later. This reduces the situation where there is a large gap between the height of the terminal block and the electrical components after it is installed inside the box, causing the wires to be bent or folded after connection, affecting the neatness of the wire arrangement and the convenience of connection. At the same time, it improves the flexibility of use and the convenience of maintenance of the blocking device.

[0019] The beneficial effects of the drawer-type wiring structure and the electricity meter disclosed in this utility model are as follows: by setting up a blocking device, the power supply can be quickly cut off as soon as a short circuit or overload occurs in the electrical components. This reduces the situation where the electrical components cannot cut off the power transmission of the wires in time when a short circuit or overload occurs, resulting in the electrical components being in a short circuit or overload state for a long time, causing the electrical components to rise in temperature and spontaneously combust, thus improving the safety of the electrical components.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0024] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] In this embodiment: Reference Figure 1 The diagram shows a preferred embodiment of the present invention.

[0026] This embodiment of a drawer-type wiring structure includes: a box 1, which is placed inside a distribution cabinet and is used to carry and install electrical components; a terminal 2, which is disposed on the box 1, wherein the wires connecting the electrical components are electrically connected to the distribution cabinet through the terminal 2; and a blocking device 4, which is disposed inside the box 1, wherein the blocking device 4 divides the wires connecting the electrical components into two segments and quickly disconnects the power supply of the wires in the event of a short circuit or overload.

[0027] Figures 2-5The blocking device 4 shown includes: a shaft frame 41, which is detachably installed inside the housing 1 via an adjusting assembly 5, wherein an electric telescopic rod 42 is provided on the shaft frame 41; a partition plate 43, which is fixedly connected to the moving end of the electric telescopic rod 42, wherein the partition plate 43 is an insulating rubber plate, and a temperature sensor 44 is provided on one side of the partition plate 43; two round hole rods 46, which are symmetrically sleeved on the shaft frame 41, and a tension spring 47 is fixedly connected between each of the two round hole rods 46 and the shaft frame 41, wherein the tension springs 47 have two... The ends are respectively fixedly connected to the round hole rod 46 and the shaft bracket 41; multiple terminals 48 are evenly fixed to the two round hole rods 46, and copper plates 49 are fixedly connected to the adjacent ends of the terminals 48 on both sides. By setting the blocking device 4, the two round hole rods 46 are first pulled closer to each other by the extension and retraction of the tension spring 47, which at the same time drives the multiple terminals 48 and copper plates 49 to move. When the tension spring 47 is in a fully compressed state, the copper plates 49 on both sides are pressed together. At this time, the wire connecting the electrical component and the terminal 2 is connected. The circuit is divided into two sections and connected to the terminals 48 on both sides. The electrical connection between the electrical component and the terminal 2 is completed using the terminals 48 and the copper plate 49. At the same time, the temperature sensor 44 uses the detection module to monitor the temperature of the electrical component inside the box 1. When the electrical component generates high temperature due to short circuit or overload, the detection module immediately inputs the detected temperature information into the control unit. The control unit controls the operation of the electric telescopic rod 42, which moves the partition plate 43 towards the copper plate 49. During the movement, the partition plate 43 squeezes the copper plates 49 on both sides, causing them to separate and disconnect the electrical connection between the wires on both sides. This cuts off the power supply to the electrical component, thus completing the overload protection of the electrical component. This reduces the possibility that the electrical component cannot be cut off from the power supply in time when a short circuit or overload occurs, resulting in the electrical component being in a short circuit or overload state for a long time, causing the electrical component temperature to rise and spontaneously combust. This improves the safety of the electrical component.

[0028] Figures 2-5A rubber ring 45 is fixed to one side of the shaft bracket 41 shown, and the position of the rubber ring 45 corresponds to that of the round hole rod 46. By setting the rubber ring 45, the round hole rod 46 can be intercepted during the movement, reducing the collision and wear between the round hole rod 46 and the shaft bracket 41 during the movement, which would affect the service life. A liquid storage box 413 is fixed to one side of the round hole rod 46, and the liquid storage box 413 is provided with a feed pipe, which is fitted with a sealing cap. The liquid storage box 413 has a hole that communicates with the inner wall of the round hole rod 46. By setting the liquid storage box 413, personnel can put glue into the liquid storage box 413, so that the glue flows into the gap between the round hole rod 46 and the shaft bracket 41 through the hole to bond and fix the round hole rod 46, increasing the stability of the round hole rod 46 and reducing the shaking caused by the elastic extension and contraction of the tension spring 47 during use, which would affect the stability of the electrical connection.

[0029] Figures 2-5 The circular rod 46 shown has a threaded groove 410 on the side near the terminal 48. A protective cover 411 is threaded onto the inner wall of the threaded groove 410. The protective cover 411 is fitted onto the surface of the terminal 48. By using the protective cover 411, the wire is first inserted through the hole in the protective cover 411, and then one end of the wire inserted into the protective cover 411 is connected to the terminal 48. At this point, the protective cover 411 is manually rotated, causing it to move left and right along the inside of the threaded groove 410. When the protective cover 411 is fully rotated into the position inside the threaded groove 410, the protective cover... The protective cover 411 completely encloses the terminal block 48 and provides protection for the internal terminal block 48 and wire core, reducing the possibility of damage to the terminal block 48 and wire core from external objects during maintenance and use, thus affecting their normal use. Multiple rubber blocks 412 are fixed to the inner wall of the hole of the protective cover 411. The rubber blocks 412 are arranged in a circle. By setting the rubber blocks 412, the surface of the inserted wire can be squeezed and assisted in limiting the position, reducing the gap between the wire and the inner wall of the hole, which would cause the wire to sway left and right, affecting the stability of the connection between the wire and the terminal block 48.

[0030] Figure 6The adjustment assembly 5 shown includes: a hole frame 51, which is fixedly connected to the inner wall of the box 1, wherein bolts 52 are threadedly connected to the inner wall of the hole frame 51, and the shaft bracket 41 is placed inside the hole frame 51 and fixed by bolts 52; and a wear-resistant plate 53, which is fixedly connected to the side of the hole frame 51 near the box 1, wherein the wear-resistant plate 53 is made of high manganese steel. By setting the adjustment assembly 5, the shaft bracket 41 is first manually moved to the position of being inserted into the hole frame 51. When the shaft bracket 41 moves to the inner wall and into any hole on the hole frame 51... When the walls overlap, the bolts 52 are manually screwed into the hole frame 51 and the shaft bracket 41 to fix the position of the shaft bracket 41, thereby completing the assembly and height adjustment between the shaft bracket 41 and the box 1. At the same time, the shaft bracket 41 can be freely disassembled later. This reduces the situation where there is a large gap between the height of the terminal block 48 and the electrical components after it is installed inside the box 1, which causes the wires to be bent or folded after connection, affecting the neatness of the wire arrangement and the convenience of connection. At the same time, it improves the flexibility of use and the convenience of maintenance of the blocking device 4.

[0031] Working principle: In use, electrical components such as circuit breakers and contactors are installed in the box 1. Then, multiple electrical components are connected to the terminals 2 on the box 1 through wires. The box 1 is then inserted into the distribution cabinet, and the terminals 2 are inserted into the ports on the distribution cabinet to realize the electrical connection between the electrical components and the distribution cabinet. At the same time, the electricity meter 3 on the box 1 displays the connection status and usage data of the electrical components.

[0032] First, manually move the shaft bracket 41 to the position inside the insertion hole frame 51. When the inner wall of the shaft bracket 41 coincides with the inner wall of any hole on the hole frame 51, manually screw the bolt 52 into the hole frame 51 and the shaft bracket 41 to fix the position of the shaft bracket 41, thereby completing the assembly and fixation and height adjustment between the shaft bracket 41 and the box body 1. At this time, under the extension and retraction of the tension spring 47, the two round hole rods 46 are pulled closer together, which in turn drives multiple terminals 48 and copper plates 49 to move. When the tension spring 47 is fully compressed, the copper plates 49 on both sides are brought into contact with each other. At this time, the wire connecting the electrical component and terminal 2 is divided into two sections and connected to the terminals 48 on both sides. The electrical connection between the electrical component and terminal 2 is completed by using the terminals 48 and copper plates 49 on both sides. At the same time, the temperature sensor 44, model HE-200A, uses the detection module to detect the electrical components inside the housing 1. Temperature monitoring is performed. When an electrical component generates high temperature due to a short circuit or overload, the detection module immediately inputs the detected temperature information into the control unit. The control unit then controls the operation of the electric telescopic rod 42, which moves the partition plate 43 towards the copper plate 49. During this movement, the partition plate 43 presses against the copper plates 49 on both sides, causing them to separate and disconnect the electrical connection between the wires on both sides. This cuts off the power supply to the electrical component, thus completing the overload protection for the electrical component.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
