Description

Technical Field

[0001] The invention belongs to the field of electric power equipment, and in particular relates to a multi-hole electric energy metering wiring device. Background Art

[0002] An electric energy metering device is a metering instrument used to measure and record electricity data such as power generation, line loss, and power consumption. It is mainly composed of an electric energy meter (active energy meter, reactive energy meter, maximum demand meter, multi-rate energy meter, etc.), a metering transformer (including a voltage transformer and a current transformer), and secondary connecting wires. An electric energy metering wiring device is required between each component to achieve convenient and quick wiring. Existing electric energy metering wiring devices generally include a plug, a socket, and a shell, wherein the plug includes an insulating shell, pins, and a wiring harness. The insulating shell is generally rectangular, with rectangular holes on the front and rear opposite sides. The end of the wiring harness extends into the insulating shell from the rear side. A plurality of the above-mentioned pins are provided at the end of the wiring harness. The pins extend evenly and dispersedly from the front side of the insulating shell. A filler is provided in the insulating shell. The filler fills the gap between the wiring harness, the pins, and the inner surface of the insulating shell, which can prevent dust from entering and provide a certain degree of protection for the pins. Prior art plugs present a problem during transportation or on-site use. Due to the plug's structure and size, using existing standard-sized boxes to hold the plugs results in a significant waste of box space. Specifically, the width of the plug's insulating housing is larger than the diameter of the wiring harness connected to its rear side, resulting in a significant gap between adjacent plugs when placed, wasting box space. Furthermore, because the box's dimensions are generally standard, the total width of the side-by-side plugs often struggles to fit within the box's dimensions, further wasting space. Furthermore, the gap between the plug and the box's inner wall can easily cause the plug to wobble or shift within the box, potentially causing scratches during transportation. Summary of the Invention

[0003] The object of the present invention is to provide a multi-hole electric energy metering wiring device, which can effectively solve the problem of large space waste when packing plug accessories in the multi-hole electric energy metering wiring device in the prior art.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a porous electric energy metering wiring device, comprising a plug, the plug comprising an insulating shell, a filler provided in the insulating shell, the filler being a flexible body, the insulating shell comprising a left side portion and a right side portion, the left side portion comprising a left top plate, a left vertical plate and a left bottom plate connected vertically in sequence, the right side portion comprising a right top plate, a right vertical plate and a right bottom plate connected vertically in sequence, the filler being fixedly bonded to the inner surfaces of the left vertical plate and the right vertical plate respectively; the right vertical plate being provided with a through groove in the vertical direction, the right top plate An upper slide is fixedly provided on the upper part and is slidably connected to the through groove. A lower slide is fixedly provided on the right bottom plate and is slidably connected to the through groove. The upper slide and the lower slide slide slide away from each other to drive the right top plate and the right bottom plate to form an accommodating cavity for the left side part to extend into. A snap assembly is provided between the left part and the right side part, and the snap assembly is used to clamp and fix the left part and the right side part after the left side part extends into the accommodating cavity. An elastic member and a locking member are provided between the upper slide and the lower slide, and the locking member is used to overcome the elastic force of the elastic member to lock the upper slide and the lower slide relative to the right vertical plate.

[0005] Preferably, the snap assembly includes an elastic card and a limiting protrusion, wherein the elastic card is provided on both the left top plate and the left bottom plate, and the limiting protrusion is provided on both the right top plate and the right bottom plate. When the left side portion is inserted into the accommodating cavity, the limiting protrusion overcomes the elastic force of the elastic card and drives the elastic card to tilt relative to the right top plate and the right bottom plate. The elastic card is provided with a groove for the limiting protrusion to engage with. In this way, when the left side portion is inserted into the accommodating cavity, the limiting protrusion abuts against the elastic card and slides relative to the elastic card. The elastic card tilts upward under the action of the limiting protrusion. When the groove aligns with the limiting protrusion, the elastic card automatically presses downward due to the elastic deformation of the elastic card itself, causing the limiting protrusion to engage with the groove, thereby achieving relative fixation of the left side portion and the right side portion.

[0006] Preferably, the end of the elastic card facing the limiting protrusion is provided with a first guiding slope, and the first guiding slope is used to slide and abut against the limiting protrusion. By providing the first guiding slope, after the elastic card slides into contact with the limiting protrusion, the elastic card will automatically tilt upward due to the force applied to the first guiding slope.

[0007] Preferably, there are multiple grooves, each parallel and spaced apart along the direction in which the left side extends into the accommodating cavity. This allows the extent to which the left side extends into the accommodating cavity to be adjusted according to the size of the box, thereby maximizing the use of the box space. Furthermore, the plugs placed in rows in the box abut against the inner wall of the box along the width direction, maintaining a certain degree of stability and preventing the plugs from shaking and scratching during transportation.

[0008] Preferably, the elastic card has a snap portion at the end facing the limiting protrusion, and the right top plate and the right bottom plate are both provided with a slot for the snap portion to engage with. In this way, on the basis of the limiting protrusion and the groove cooperating to limit the position, the snap portion and the slot cooperating to limit the position further enhance the stability of the connection between the left and right parts.

[0009] Preferably, the buckle portion is provided with a second guide slope at one end thereof facing the limiting protrusion, the second guide slope being configured to slide in contact with the protrusion. By providing the second guide slope, the buckle portion will automatically tilt upwards due to the force exerted on the second guide slope after the buckle portion slides into contact with the limiting protrusion.

[0010] Preferably, the right top plate and right bottom plate are each provided with a plurality of slots, arranged parallel and spaced apart along the direction in which the left side portion extends into the accommodating cavity, and the elastic card is provided with a plurality of corresponding grooves. This allows the extent to which the left side portion extends into the accommodating cavity to be adjusted according to the size of the box, thereby maximizing the utilization of the box space. At the same time, the plugs placed in rows in the box abut against the inner wall along the width direction, maintaining a certain degree of stability and preventing the plugs from shaking and scratching during transportation.

[0011] The locking member is an L-shaped clip, and the two ends of the elastic member are respectively connected to the upper slide plate and the lower slide plate, the upper end of the locking member is connected to the upper slide plate, and the lower slide plate is provided with a vertical slot for the sliding connection of the lower section of the locking member, and the inner wall of the vertical slot is provided with a guide slot communicating with the vertical slot, and the guide slot is provided with an upper limit position and a lower limit position. When the right top plate and the right bottom plate are pressed to drive the L-shaped clip to engage the upper limit position, the upper slide plate and the lower slide plate slide closer to each other relative to each other, and when the right top plate and the right bottom plate are pressed to drive the L-shaped clip to engage the lower limit position, the upper slide plate and the lower slide plate slide away relative to each other to form the accommodating cavity. By providing the compression spring, the L-shaped clip and the guide slot, the relative sliding of the upper slide plate and the lower slide plate is easy to control. The operator only needs to press the right top plate and the right bottom plate in the vertical direction and then release the hand to realize the relative opening and returning of the right top plate and the right bottom plate, which is very simple to operate.

[0012] Preferably, the L-shaped clamp includes a vertical rod and a pin vertically fixedly connected to the bottom end of the vertical rod, and the upper end of the vertical rod is rotatably hinged to the right top plate.

[0013] Preferably, the wiring device further comprises a socket, wherein the right top plate and the right bottom plate are each provided with a plug post on their end surfaces facing the socket, and the socket is provided with a slot for inserting the plug post. The insertion of the plug post into the slot is used to prevent the right top plate and the right bottom plate from sliding relative to the right vertical plate. The provision of the slot and the plug post can prevent misoperation after the plug is inserted into the socket, and prevent the right top plate and the right bottom plate of the plug from opening after insertion into the socket.

[0014] Compared with the prior art, the present invention has the following beneficial effects: by splitting the insulating shell of the plug into two parts and selecting a flexible body as the filler, the left and right sides of the filler are fixedly bonded to the inner surfaces of the left vertical plate and the right vertical plate respectively, thereby maintaining the stability of the connection between the insulating shell and the filler; when the plug needs to be transported, by unlocking the locking piece, the elastic force of the elastic piece is used to drive the upper slide and the lower slide to slide relative to the right vertical plate, so that the right top plate and the right bottom plate slide relative to each other and away from each other to form an accommodating cavity for the left side part to extend into, and then squeezing left and right can reduce the size of the plug in the width direction (the filler is a flexible body that can be squeezed), and after squeezing into place, the left and right parts can be clamped and fixed by the snap assembly, thereby reducing the occupied volume and improving the utilization rate of the internal space of the box; when it needs to be used, the left and right parts are restored to their original state, and the upper and lower slides are locked by the locking piece to ensure stability.

[0028] Embodiment 1: This embodiment provides a multi-hole electric energy metering wiring device, which includes a plug, such as Figures 1 to 5As shown, the plug includes an insulating housing 1. The insulating housing 1 is rectangular and has rectangular holes on opposite front and rear sides. The end of the wiring harness 6 extends into the insulating housing 1 from the rear. The end of the wiring harness 6 is provided with multiple pins 7, which extend evenly and dispersedly from the front of the insulating housing 1. A filler 8 is provided within the insulating housing 1 to fill the gaps between the wiring harness 6, the pins 7, and the inner surface of the insulating housing 1, preventing dust from entering and providing some protection for the pins 7. In this embodiment, the filler 8 is a flexible material, specifically rubber. The insulating shell 1 includes a left side portion 2 and a right side portion 3. The left side portion 2 includes a left top plate 21, a left vertical plate 20 and a left bottom plate 22 connected vertically in sequence. The right side portion 3 includes a right top plate 31, a right vertical plate 30 and a right bottom plate 32 connected vertically in sequence. The filler 8 is fixedly bonded to the inner surfaces of the left vertical plate 20 and the right vertical plate 30 respectively; the right vertical plate 30 is provided with a through groove 300 in the vertical direction, the right top plate 31 is fixedly provided with an upper slide plate 33 slidably connected in the through groove 300, and the right bottom plate 32 is fixedly provided with a The lower slide plate 34, the upper slide plate 33 and the lower slide plate 34 in the 300 slide away from each other to drive the right top plate 31 and the right bottom plate 32 to form an accommodating cavity 10 for the left side portion 2 to extend into. A snap assembly is provided between the left side portion 2 and the right side portion 3. The snap assembly is used to clamp the left side portion 2 and the right side portion 3 after the left side portion 2 extends into the accommodating cavity 10. An elastic member and a locking member are provided between the upper slide plate 33 and the lower slide plate 34. The locking member is used to overcome the elastic force of the elastic member and lock the upper slide plate 33 and the lower slide plate 34 relative to the right vertical plate 30. It should be noted that the "front", "rear", "left" and "right" in this embodiment refer to the front, rear and left sides of the 300. Figure 1 In the direction shown in , that is, the direction pointed by the pin 7 is the front, and the side where the wiring harness 6 is located is the rear.

[0029] In this embodiment, the insulating shell 1 of the plug is designed to be divided into two parts, and a flexible body is selected as the filler 8. The left and right sides of the filler 8 are fixedly bonded to the inner surfaces of the left vertical plate 20 and the right vertical plate 30 respectively, so as to maintain the stability of the connection between the insulating shell 1 and the filler 8. When the plug needs to be transported, the locking member is unlocked and the elastic force of the elastic member is used to drive the upper slide plate 33 and the lower slide plate 34 to slide relative to the right vertical plate 30. In this way, the right top plate 31 and the right bottom plate 32 slide relative to each other and move away from each other to form an accommodating cavity 10 for the left side part 2 to extend into. Then, the left and right squeezing can reduce the width dimension of the plug (the filler 8 is a flexible body that can be squeezed). After squeezing into place, the left side part 2 and the right side part 3 can be clamped and fixed by the snap assembly, so as to reduce the occupied volume and improve the utilization rate of the internal space of the box. When it is needed, the left side part 2 and the right side part 3 are restored to their original state, and the upper slide plate 33 and the lower slide plate 34 are locked by the locking member to ensure stability.

[0030] Specifically, such as Figure 3 and Figure 4 As shown, the snap assembly in this embodiment includes an elastic clip 23 and a limiting protrusion 35. The elastic clip 23 is provided on both the left top plate 21 and the left bottom plate 22, and the limiting protrusion 35 is provided on both the right top plate 31 and the right bottom plate 32. When the left side portion 2 is inserted into the accommodating cavity 10, the limiting protrusion 35 overcomes the elastic force of the elastic clip 23 and drives the elastic clip 23 to tilt relative to the right top plate 31 and the right bottom plate 32. The elastic clip 23 is provided with a groove 230 into which the limiting protrusion 35 engages. As the left side portion 2 is inserted into the accommodating cavity 10, the limiting protrusion 35 abuts against and slides relative to the elastic clip 23. The elastic clip 23 tilts upward under the action of the limiting protrusion 35. When the groove 230 aligns with the limiting protrusion 35, the elastic clip 23 automatically presses downward due to its own elastic deformation, causing the limiting protrusion 35 to engage with the groove 230, thereby achieving relative fixation between the left side portion 2 and the right side portion 3. To facilitate the automatic engagement of the stop protrusion 35 with the groove 230, a first guide slope 231 is provided on the end of the elastic clip 23 facing the stop protrusion 35 in this embodiment. The first guide slope 231 is configured to slide in contact with the stop protrusion 35. By providing the first guide slope 231, once the elastic clip 23 slides into contact with the stop protrusion 35, the force exerted on the first guide slope 231 causes the elastic clip 23 to automatically tilt upward.

[0031] To further maximize the space within the box and prevent the plugs from shaking and scratching during transport, multiple grooves 230 are provided in this embodiment. These grooves 230 are arranged parallel and spaced apart along the direction in which the left side portion 2 extends into the accommodating cavity 10. This allows the extent to which the left side portion 2 extends into the accommodating cavity 10 to be adjusted according to the box size, thereby maximizing the use of the box space. Furthermore, the plugs placed in rows within the box abut against the inner wall along the width direction, maintaining a certain degree of stability and preventing the plugs from shaking and scratching during transport.

[0032] like Figure 5 、 Figure 6 and Figure 7As shown, the elastic member in this embodiment is a compression spring 4, and the locking member is an L-shaped clip 5. The two ends of the elastic member are respectively connected to the upper slide plate 33 and the lower slide plate 34. The upper end of the locking member is connected to the upper slide plate 33, and the lower slide plate 34 is provided with a vertical groove 340 for the sliding connection of the lower section of the locking member. The inner wall of the vertical groove 340 is provided with a guide groove 341 connected to the vertical groove 340, and the guide groove 341 is provided with an upper limit position 342 and a lower limit position 343. When the right top plate 31 and the right bottom plate 32 are pressed to drive the L-shaped clip 5 to be clamped into the upper limit position 342, the upper slide plate 33 and the lower slide plate 34 slide closer to each other. When the right top plate 31 and the right bottom plate 32 are pressed to drive the L-shaped clip 5 to be clamped into the lower limit position 343, the upper slide plate 33 and the lower slide plate 34 slide away from each other and form an accommodating cavity 10. The compression spring 4, L-shaped clamp 5, and guide slot 341 facilitate the controlled relative sliding of the upper and lower slides 33 and 34. The operator simply presses the right top plate 31 and right bottom plate 32 vertically and then releases them to open and return them to their original positions, making operation extremely simple. The L-shaped clamp 5 comprises a vertical rod 50 and a pin 51 vertically fixed to the bottom end of the vertical rod 50. The top end of the vertical rod 50 is pivotally hinged to the right top plate 31.

[0033] In order to prevent the plug from being operated incorrectly after being inserted into the socket and to prevent the right top plate 31 and the right bottom plate 32 of the plug from being opened after being inserted into the socket, the wiring device provided in this embodiment also includes a socket, and the right top plate 31 and the right bottom plate 32 are provided with plug-in posts on the end surfaces facing the socket, and the socket is provided with slots for inserting the plug-in posts. The insertion of the plug-in posts into the slots is used to prevent the right top plate 31 and the right bottom plate 32 from sliding relative to the right vertical plate 30. In this way, by providing the slots and the plug-in posts, it is possible to prevent the plug from being operated incorrectly after being inserted into the socket and to prevent the right top plate 31 and the right bottom plate 32 of the plug from being opened after being inserted into the socket.

[0034] Embodiment 2: This embodiment also provides a multi-hole electric energy metering wiring device, such as Figure 8 and Figure 9 As shown, the difference between this embodiment and the above embodiment is that in this embodiment, a buckle portion 24 is provided at the end of the elastic card 23 facing the limiting protrusion 35, and a slot 36 for the buckle portion 24 to be inserted into is provided on the right top plate 31 and the right bottom plate 32.

[0035] Based on the above-mentioned distinguishing technical features, on the basis of the limiting protrusion 35 and the groove 230 cooperating to limit, the buckle part 24 and the card slot 36 cooperate to limit, further enhancing the stability of the connection between the left part 2 and the right part 3.

[0036] Similarly, to facilitate the automatic insertion of the latch portion 24 into the latch slot 36, in this embodiment, a second guide slope 240 is provided on the end of the latch portion 24 facing the limiting protrusion 35. The second guide slope 240 is configured to slide against the protrusion. By providing the second guide slope 240, after the latch portion 24 slides into contact with the limiting protrusion 35, the force exerted on the second guide slope 240 causes the latch portion 24 to automatically tilt upward. Furthermore, in this embodiment, multiple latch slots 36 are provided. Specifically, multiple latch slots 36 are provided on both the right top plate 31 and the right bottom plate 32. The multiple latch slots 36 are arranged parallel and spaced apart along the direction in which the left side portion 2 extends into the accommodating cavity 10. The elastic card 23 is correspondingly provided with multiple grooves 230. In this way, the extent to which the left side portion 2 extends into the accommodating cavity 10 can be adjusted according to the size of the box, thereby making the most of the box space. At the same time, the plugs placed in rows in the box can abut against the inner wall of the box along the width direction, thereby maintaining a certain degree of stability and preventing the plugs from shaking and causing scratches during transportation.

[0037] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
