Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a connector for connecting an electricity meter. Background Technology

[0002] An electricity meter connector is an interface device used to connect an electricity meter to a power system. As a key component of electricity metering equipment, the reliability and durability of the connector's terminals directly affect the long-term stable operation of the electricity meter.

[0003] Existing connectors typically use a split cover plate structure to protect the screws. Specifically, during operation, the cover plate covering the outside of the screw must be completely removed and placed independently. After the cable connection is completed, the cover plate is reassembled. However, the removed cover plate needs to be temporarily stored in the external environment, and it is easy to lose or become contaminated under complex working conditions. This causes contaminants to adhere to the screw surface during reassembly, accelerating metal corrosion and increasing disassembly resistance. Moreover, the cover plate's sealing performance is insufficient, especially for carbon steel screws. In dark and humid environments, moisture can penetrate, accelerating oxidation and corrosion. In severe cases, it can cause the screw to fail to engage with the screw hole, which is detrimental to cable installation and removal. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a connector for connecting electricity meters.

[0005] The technical solution of this utility model is as follows:

[0006] A connector for connecting an electricity meter includes a connector body, which includes a conductive element and a conductive base connected thereto. The conductive base is provided with a screw for connecting a cable corresponding to the conductive element and a through hole for the cable corresponding to the screw. One side of the conductive base where the screw is located is a disassembly surface, and the other side of the conductive base where the through hole is located is a through surface. A rotating shaft is rotatably provided at the intersection of the disassembly surface and the through surface. A cover plate is provided on the rotating shaft along its length. A first sealing element is provided on the side of the cover plate that is close to the screw. The first sealing element has a closed-loop structure and is located outside multiple screws when the cover plate is close to the outside of the screws, and is in close contact with the disassembly surface.

[0007] The cover plate is detachably connected to the conductive base via a first connector;

[0008] The first sealing element contains multiple second sealing elements corresponding to the screws;

[0009] The cover plate has multiple cable limiting components on the side away from the pivot, corresponding to the cable threading holes.

[0010] Furthermore, the disassembly surface has screw mounting holes that are compatible with screws, and the tip of the screw can be located inside the screw mounting hole when tightened. The thickness of the second seal is greater than that of the first seal.

[0011] The specific structure of the aforementioned cable limiting component is as follows: the cable limiting component includes an elastic damping strip, and the cover plate has multiple limiting arc-shaped holes corresponding to the wire through holes on the side away from the rotating shaft. The damping strip is arranged around the inner wall of the limiting holes, and the opening of the limiting arc-shaped holes is consistent with the outer diameter of the cable. The damping strip has a certain friction force, and the cable can pass through the damping strip when wiring. Under the friction and clamping force of the damping strip, the cable can be limited, which facilitates the wiring operation of the cable.

[0012] In order to clamp the cable during wiring, the notches formed at both ends of the damping strip are located outside the limiting arc hole, and the size of the notch is smaller than the outer diameter of the cable.

[0013] To ensure that the damping strip does not interfere with the mounting hole of the sealing screw of the first sealing strip, the thickness of the side of the damping strip protruding near the cover plate where the first sealing strip is located shall not exceed the thickness of the first sealing element.

[0014] The specific structure of the first sealing element is as follows: the first sealing element is made of elastic rubber material, and the structure of the first sealing element is elliptical or rectangular.

[0015] To ensure that the cover plate can rotate to be parallel to both the disassembly surface and the perforation surface, the axis of the rotating shaft is located outside the horizontal plane containing both the disassembly surface and the perforation surface, and the vertical distance between the axis and the disassembly surface and the vertical distance between the axis and the perforation surface are the same.

[0016] Furthermore, the perpendicular distance between the center of the limiting arc hole and the axis of the rotating shaft is the same as the perpendicular distance between the center of the threading hole and the axis of the rotating shaft.

[0017] The conductive base is provided with a rotating seat adapted to the rotating shaft, and the rotating seat is provided with a second connecting member. One end of the second connecting member can pass through the rotating seat and abut against the outer surface of the rotating shaft.

[0018] The beneficial effects of this utility model are as follows:

[0019] The rotating shaft is located at the lower part of the disassembly surface and at the intersection of the disassembly surface and the wire threading surface, so that when the cover plate on it rotates upward, it can cover the disassembly surface. The first seal is in contact with the disassembly surface, and the second seal can be inserted into the screw mounting hole where the screw is located after tightening. By tightening the first connector, the first seal is pressed down and pressed tightly against the disassembly surface, and the second seal is pressed tightly against the outer end of the screw. The first seal and the second seal work together to seal and protect the screw and the inside of the screw mounting hole, reducing the occurrence of rust, corrosion and other phenomena in the screw. After the cover plate is removed from the disassembly surface, it will be hung on the conductive base, and there will be no loss or contamination.

[0020] The cover plate has a limiting function on the side away from the pivot to limit the cables to be connected. The head of the cable to be connected passes through the limiting arc hole, so that the damping strip contacts the insulation of the cable. The damping strip has a large friction force. The structure formed by the damping strip around the limiting arc hole can clamp the cable. It can limit the movement of the cable after the head of the cable is inserted into the wire hole and before the screw is tightened. The operator does not need to hold the cable all the time. The heads of multiple cables can be inserted into the corresponding wire holes. After being limited by the cover plate and the damping strip, multiple screws can be tightened at the same time, which improves the wiring efficiency.

[0021] To ensure that the cable threading and clamping are not affected when the cover plate is rotated downwards to the cable threading surface, a second connector is provided on the conductive base to connect the rotating shaft and the rotating seat. The second connector can restrict the rotation of the rotating shaft, thereby restricting the rotation of the cover plate and the cable on it, so that the clamped cable can be held at a certain fixed angle, which is convenient for installing the cable by tightening the screws.

[0032] See Figure 1 , Figure 2 and Figure 7 As shown, a connector for connecting an electricity meter includes a connector body 1. The connector body 1 is a prior art technology and is used vertically. The connector body 1 includes conductive elements 101 and conductive bases 102 connected thereto. In this embodiment, there are four conductive elements 101. The conductive elements 101 are electrically connected to the electricity meter and are vertically connected by plugging. The conductive base 102 is provided with screws 2 for connecting cables corresponding to the conductive component 101 and wire holes 103 for passing cables through the screws 2. One side of the conductive base 102 where the screws 2 are located is the disassembly surface 1022, and the other side of the conductive base 102 where the wire holes 103 are located is the wire passing surface 1023. A rotating shaft 3 is rotatably provided at the intersection of the disassembly surface 1022 and the wire passing surface 1023. A cover plate 5 is provided on the rotating shaft 3 along its length direction. A first sealing element 6 is provided on the side of the cover plate 5 that is close to the screws 2. The first sealing element 6 is a closed-loop structure. When the cover plate 5 is close to the outside of the screws 2, the first sealing element 6 is located outside the four screws 2 and is in close contact with the disassembly surface 1022.

[0033] The conductive base 102 is provided with a rotating seat 4 adapted to the rotating shaft 3. There are two rotating seats 4, located at both ends of the rotating shaft 3. The rotating shaft 3 is rotatably connected to the rotating seat 4 and will not detach from the rotating seat 4. The connection method between the rotating seat 4 and the rotating shaft 3 is the prior art. One of the rotating seats 4 is provided with a second connecting member 9. One end of the second connecting member 9 can pass through the rotating seat 4 and abut against the outer surface of the rotating shaft 3. The first connecting member 8 is threadedly connected to the rotating seat 4.

[0034] The cover plate 5 is detachably connected to the conductive base 102 via a first connector 8. The first connector 8 can be a fastening bolt. A first threaded hole 502 is provided in the middle of the cover plate 5, away from the rotating shaft 3. A second threaded hole 1021 corresponding to the first threaded hole 502 is provided on the disassembly surface 1022. The first connector 8 passes through the first threaded hole 502 and is threadedly connected to the second threaded hole 1021. By tightening the first connector 8, the first sealing member 6 can be pressed against the disassembly surface 1022, providing a sealing and protective function for the screw 2.

[0035] See Figure 3 As shown, in order for the cover plate 5 to rotate to be parallel to the disassembly surface 1022 during rotation (see... Figure 4 It can also be rotated to be parallel to the perforated surface (see...). Figure 5The axes of the rotating shaft 3 are all located outside the horizontal plane containing the disassembly surface 1022 and the threading surface 1023, and the vertical distance between the axis and the disassembly surface 1022 and the vertical distance between the axis and the threading surface 1023 are the same. The vertical distance between the center of the limiting arc hole 501 and the axis of the rotating shaft 3 and the vertical distance between the center of the threading hole 103 and the axis of the rotating shaft 3 are the same.

[0036] See Figure 6 As shown, the specific structure of the first sealing element 6 is an elliptical or rectangular structure. The first sealing element 6 contains four second sealing elements 7, each corresponding to a screw 2. Both the first sealing element 6 and the second sealing element 7 are made of waterproof and elastic rubber, which serves a sealing function.

[0037] The disassembly surface 1022 has four screw mounting holes 1024 that are compatible with the screw 2. The top of the screw 2 can be located inside the screw mounting hole 1024 when it is tightened. The thickness of the second sealing element 7 is greater than that of the first sealing element 6. The first sealing element 6 works with the second sealing element 7 to seal and protect the screw 2 and the inside of the screw mounting hole 1024, reducing the occurrence of rust and corrosion of the screw 2. After the cover plate 5 is removed from the disassembly surface 1022, it will be hung on the conductive base 102, and there will be no loss or contamination.

[0038] Four cable limiting components corresponding to the wire-passing holes 103 are provided on the side of the cover plate 5 away from the rotating shaft 3. The specific structure of these cable limiting components is as follows: each cable limiting component includes an elastic damping strip 10. The damping strip 10 has a certain degree of hardness, especially at its end, allowing the cable to pass through while providing some support. The material is selected based on actual conditions. Multiple limiting arc-shaped holes 501 corresponding to the wire-passing holes 103 are provided on the side of the cover plate 5 away from the rotating shaft 3. The damping strip 10 is arranged around the inner wall of the limiting arc-shaped holes 501. The damping strip 10 can be fixed inside the limiting arc-shaped holes 501 by means of adhesive or other methods. The opening of the limiting arc-shaped holes 501 is consistent with the outer diameter of the cable. The damping strip 10 has a certain frictional force, allowing the cable to pass through it during wiring. Under the friction and clamping force of the damping strip 10, the cable is limited, facilitating the wiring operation.

[0039] It should be noted that the side of the cover plate 5 away from the rotating shaft 3 is designed to limit the cables to be connected. The head of the cable to be connected passes through the limiting arc hole 501, allowing the damping strip 10 to contact the cable insulation. The damping strip has a large frictional force, and the structure formed by the damping strip 10 around the limiting arc hole 501 can clamp the cable, squeezing it tightly within the damping strip 10. This restricts cable movement after the cable head is inserted into the wire hole 103, before tightening the screw 2. This eliminates the need for the operator to hold the cable continuously; multiple cable heads can be inserted into their corresponding wire holes 103, and the second connector 9 can be tightened. After being limited by the damping strip, multiple screws 2 can be tightened simultaneously, improving wiring efficiency. It should be noted that before threading the cable through the arc hole, the first connector 8 must be removed to prevent it from interfering with the rotation of the cover plate 5 to the wire threading surface 1023.

[0040] To clamp the cable during wiring, the notches formed at both ends of the damping strip 10 are located outside the limiting arc-shaped hole 501, and the notch size is smaller than the outer diameter of the cable. To ensure that the damping strip 10 does not affect the mounting hole 1024 of the sealing screw of the first sealing strip, the thickness of the side of the damping strip 10 protruding near the cover plate where the first sealing strip is located is no greater than the thickness of the first sealing element 6.
