Description

Technical Field

[0001] The present application relates to the technical field of electrical connection, and in particular to a secondary equipotential copper cable wiring device. Background Art

[0002] In the power system, secondary wiring is a key link to ensure the normal operation of equipment and data transmission. The traditional wiring method may have potential differences.

[0003] The utility model patent with announcement number CN211579154U proposes an equipotential connector, including a protective sleeve, a wire is fixedly installed inside the protective sleeve, a terminal is fixedly installed at one end of the wire, a filling layer is fixedly installed on one side of the wire, an electrode is fixedly installed at one end of the wire, and a protective layer is provided at one end of the electrode.

[0004] The device connects the cables through an equipotential connector formed by a protective sleeve, a conductor, a terminal block and an electrode. When a potential difference occurs between the circuits connected by the equipotential connector,

[0005] Discharge is carried out through the gap formed between the two electrodes, making the potential between the two electrical appliances equal.

[0006] When connecting the above-mentioned equipotential connector, the cable needs to be wrapped and fixed on the terminal. In order to avoid leakage at the connection and ensure the stability of the connection, it needs to be repeatedly wrapped with waterproof tape after the connection, which is not only unsightly but also has low connection efficiency. Utility Model Content

[0007] The utility model aims to solve or at least alleviate the problem that the existing equipotential connector needs to be repeatedly wrapped with waterproof tape to avoid leakage at the connection and ensure the stability of the connection after wiring, which is not only unsightly but also has low connection efficiency.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A secondary equipotential copper cable wiring device comprises an equipotential connector with connecting sleeves fixedly connected at both ends, a cavity is formed inside the connecting sleeve, and a connecting terminal electrically connected to the internal electrode of the equipotential connector through a wire is arranged in the cavity, a sealing cover is arranged at one end of the connecting sleeve away from the equipotential connector, two symmetrically arranged metal springs are fixedly connected to the inner wall of the sealing cover, a clamping column is fixedly connected to one end of the metal spring located outside the sealing cover, a clamping hole aligned with the clamping column is opened on the side wall of the connecting sleeve, and a clamping structure for clamping and fixing the copper cable body is also fixedly connected to the outer side of the sealing cover.

[0010] By adopting the above technical scheme, when using, the user first passes the copper cable body terminal through the clamping tube and the through hole, and then screws the inner screw ring to squeeze the side wall of the clamping tube and shrink inward along the shrinkage groove until it is tightly fitted with the copper cable body to fix the copper cable body. At this time, the two metal springs are pressed toward each other to make the two metal springs produce elastic deformation, and then the two metal springs are inserted into the connecting sleeve, and the metal springs are released. At this time, the metal springs push the clamping column to be inserted into the clamping hole under the action of their own restoring force. At the same time, the copper cable body terminal that passes through the clamping tube and the through hole is just embedded in the wiring terminal, and is electrically connected to the equipotential connector through the wire. Since the connection between the end of the copper wire body and the wiring terminal is located in a closed structure formed by the combination and splicing of the connecting sleeve and the sealing cover, there is no need to wrap it with waterproof tape, which avoids the problem that the existing equipotential connector needs to be repeatedly wrapped with waterproof tape to avoid leakage at the connection and ensure the stability of the connection after wiring, which is not only unsightly but also has low connection efficiency.

[0011] Optionally, the wiring terminal has a U-shaped structure, a slot is provided inside the wiring terminal, and the inner cavity width of the slot is equal to the diameter of the copper cable body.

[0012] By adopting the above technical solution, when in use, the copper cable body terminal is bent to form a ring structure, and the copper cable body end of the ring structure is inserted into the card slot to increase the contact area between the copper cable body end and the terminal, thereby minimizing the resistance at the connection between the copper cable body end and the terminal.

[0013] Optionally, an insulating plate is fixedly connected to the wiring terminal, a spring is sleeved on the outer surface of the wire, one end of the spring is fixedly connected to the insulating plate, and the other end of the spring is fixedly connected to the inner wall of the connecting sleeve.

[0014] By adopting the above technical solution, an insulating plate is provided to isolate the current, so as to avoid the spring from contacting the terminal as much as possible, thereby preventing the current from leaking easily through the spring.

[0015] Optionally, when the clamping column installed at the end of the metal spring is clamped with the clamping hole opened on the side wall of the connecting sleeve, the spring is squeezed by the end of the copper cable body and is in a compressed state.

[0016] By adopting the above technical solution, the restoring force of the compressed spring is used to push the terminal block toward the end of the copper cable body, so that the terminal block can fit tightly with the end of the copper cable body, thereby ensuring that the terminal block and the end of the copper cable body always maintain a stable contact pressure during the connection process, further improving the conductivity and connection stability.

[0017] Optionally, the clamping column has a cylindrical structure, the length of the clamping column is greater than the thickness of the side wall of the connecting sleeve, and the diameter of the free end of the clamping column is smaller than the aperture of the clamping hole.

[0018] By adopting the above technical solution, the diameter of the free end of the clamping column is set to be smaller than the hole diameter of the clamping hole. After the clamping column and the clamping hole are aligned, the metal spring can push the clamping column to be inserted into the clamping hole through its own elastic force.

[0019] Optionally, a sealing ring with an annular structure is provided on one adjacent side of the two sealing covers, and the sealing ring is bonded to the peripheral side of the end of the sealing cover.

[0020] By adopting the above technical solution, a sealing ring is provided to seal the connection between the sealing cover and the end of the connecting sleeve, thereby improving the waterproof performance of the connection between the sealing cover and the end of the connecting sleeve.

[0021] Optionally, the clamping structure includes a funnel-shaped clamping tube fixedly connected to the outer wall of the sealing cover, a plurality of symmetrically distributed shrinkage grooves are opened on the side wall of the clamping tube, and an inner screw ring threadedly connected to the clamping tube is sleeved on the outer surface of the clamping tube.

[0022] By adopting the above technical solution, when in use, the connection terminal of the copper cable body is passed through the inner cavity of the clamping tube, and then the inner screw ring is screwed so that the inner screw ring squeezes the side wall of the clamping tube and shrinks inward along the shrinkage groove until it fits tightly with the copper cable body, thereby fixing the copper cable body.

[0023] Optionally, a through hole is provided on the side wall of the sealing cover at the side where the sealing cover is connected to the clamping tube, and the inner diameter of the through hole is larger than the diameter of the wire.

[0024] By adopting the above technical solution, a through hole is set so that the copper cable body can extend into the connecting sleeve through the through hole after passing through the clamping tube, and be clamped with the wiring terminal set in the inner cavity of the connecting sleeve. The inner diameter of the through hole is larger than the diameter of the wire, which is convenient for passing through the copper cable body.

[0025] In summary, the beneficial effects of this application are as follows:

[0026] The present application achieves coordinated arrangement among structures such as a connecting sleeve, a wiring terminal, a sealing cover, a metal spring and a clamping column. The wiring terminal is arranged in the cavity of the connecting sleeve. The wiring end of the copper cable body passes through the sealing cover and is clamped and fixed by a clamping tube and then extends into the connecting sleeve to be clamped to the wiring terminal. The sealing cover is clamped to the side wall of the connecting sleeve through the clamping column. The connection between the end of the copper wire body and the wiring terminal is sealed in the connecting sleeve without the need to wrap it with waterproof tape. This avoids the problem that the existing equipotential connector needs to be repeatedly wrapped with waterproof tape after wiring to avoid leakage at the connection and ensure the stability of the connection, which is not only unsightly but also has low connection efficiency.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] See also Figure 1-3 A secondary equipotential copper cable wiring device comprises an equipotential connector 1 with connecting sleeves 2 fixedly connected at both ends.

[0033] A cavity 3 is formed inside the connecting sleeve 2, and a wiring terminal 5 electrically connected to the internal electrode of the equipotential connector 1 through a wire 7 is provided in the cavity 3, so that the copper cable can be electrically connected to the equipotential connector 1 through the wiring terminal 5. When a potential difference is generated, discharge is performed using the gap formed between the two electrodes in the equipotential connector 1, so that the potential between the copper cables at both ends of the equipotential connector 1 is equal.

[0034] A sealing cover 9 is provided at one end of the connecting sleeve 2 away from the equipotential connector 1, and two symmetrically arranged metal springs 10 are fixedly connected to the inner wall of the sealing cover 9. A clamping column 11 is fixedly connected to one end of the metal spring 10 located outside the sealing cover 9, and a clamping hole 12 aligned with the clamping column 11 is opened on the side wall of the connecting sleeve 2. When it is necessary to fix the sealing cover 9 to the end of the connecting sleeve 2, the two metal springs 10 can be pressed toward each other to make the two metal springs 10 produce elastic deformation, and then the two metal springs 10 are inserted into the connecting sleeve 2, and the metal springs 10 are released. At this time, the metal springs 10 push the clamping column 11 to be inserted into the clamping hole 12 under the action of their own restoring force, thereby realizing the installation and fixation of the sealing cover 9.

[0035] A clamping structure for clamping and fixing the copper cable body 17 is also fixedly connected to the outside of the sealing cover 9. The copper cable body 17 is fixed by the clamping structure to prevent the end of the copper cable body 17 electrically connected to the terminal 5 from being separated from the terminal 5 after being received.

[0036] Reference Figure 2The terminal block 5 is a U-shaped structure, and a slot 6 is provided inside the terminal block 5. The inner width of the slot 6 is equal to the diameter of the copper cable body 17. When in use, the terminal of the copper cable body 17 is bent to form a ring structure, and the end of the copper cable body 17 of the ring structure is inserted into the slot 6 to increase the contact surface between the end of the copper cable body 17 and the terminal block 5, thereby minimizing the resistance at the connection between the end of the copper cable body 17 and the terminal block 5.

[0037] Reference Figure 1 The connecting terminal 5 is fixedly connected with an insulating plate 4, and the outer surface of the wire 7 is sleeved with a spring 8, one end of the spring 8 is fixedly connected with the insulating plate 4, and the other end of the spring 8 is fixedly connected with the inner wall of the connecting sleeve 2. The insulating plate 4 is provided to isolate the current and avoid the contact between the spring 8 and the connecting terminal 5 as much as possible, which may cause the current to leak easily through the spring 8.

[0038] Reference Figure 2 When the clamping column 11 installed at the end of the metal spring 10 is clamped with the clamping hole 12 opened on the side wall of the connecting sleeve 2, the spring 8 is squeezed by the end of the copper cable body 17 and is in a compressed state. The restoring force of the spring 8 in a compressed state is used to push the terminal 5 to move toward the end of the copper cable body 17, so that the terminal 5 can fit closely with the end of the copper cable body 17, so as to ensure that the terminal 5 and the end of the copper cable body 17 always maintain a stable contact pressure during the connection process, further improving the conductivity and connection stability.

[0039] Reference Figure 1 The clamping column 11 is cylindrical in structure, the length of the clamping column 11 is greater than the thickness of the side wall of the connecting sleeve 2, and the diameter of the free end of the clamping column 11 is smaller than the aperture of the clamping hole 12. The diameter of the free end of the clamping column 11 is set to be smaller than the aperture of the clamping hole 12. After the clamping column 11 and the clamping hole 12 are aligned, it is convenient for the metal spring 10 to push the clamping column 11 to be inserted into the clamping hole 12 through its own elastic force.

[0040] Reference Figure 2 The adjacent sides of the two sealing covers 9 are each provided with a sealing ring 13 of an annular structure, and the sealing ring 13 is bonded to the peripheral side of the end of the sealing cover 9. The sealing ring 13 is provided to seal the connection between the sealing cover 9 and the end of the connecting sleeve 2, thereby improving the waterproof performance of the connection between the sealing cover 9 and the end of the connecting sleeve 2.

[0041] Reference Figure 1 and Figure 3The clamping structure includes a clamping tube 14 in a funnel-shaped structure fixedly connected to the outer wall of the sealing cover 9, a plurality of symmetrically distributed contraction grooves 15 are provided on the side wall of the clamping tube 14, and an inner screw ring 16 is sleeved on the outer surface of the clamping tube 14 and screwed with the clamping tube 14. When in use, the connection end of the copper cable body 17 is passed through the inner cavity of the clamping tube 14, and then the inner screw ring 16 is screwed to squeeze the side wall of the clamping tube 14 and contract inward along the contraction groove 15 until it is tightly fitted with the copper cable body 17, thereby achieving the fixing of the copper cable body 17.

[0042] Reference Figure 1 A through hole is provided on the side wall of the sealing cover 9 connected to the clamping tube 14, and the inner diameter of the through hole is larger than the diameter of the wire 7. The through hole is provided so that the copper cable body 17 can extend into the connecting sleeve 2 through the through hole after passing through the clamping tube 14, and be clamped with the connecting terminal 5 provided in the inner cavity of the connecting sleeve 2. The inner diameter of the through hole is larger than the diameter of the wire 7, so that the copper cable body 17 can pass through.

[0043] The implementation principle of the present application is as follows: when in use, the user first passes the terminal of the copper cable body 17 through the clamping tube 14 and the through hole, and then screws the inner screw ring 16 to squeeze the side wall of the clamping tube 14 and shrink inward along the shrinkage groove 15 until it fits tightly with the copper cable body 17 to fix the copper cable body 17. At this time, the two metal springs 10 are pressed toward each other to make the two metal springs 10 produce elastic deformation, and then the two metal springs 10 are inserted into the connecting sleeve 2, and the metal springs 10 are released. At this time, the metal springs 10 push the clamping column 11 to be inserted under the action of their own restoring force. To the clamping hole 12, at the same time, the wiring end of the copper cable body 17 that passes through the clamping tube 14 and the through hole is just embedded in the wiring terminal 5, and is electrically connected to the equipotential connector 1 through the wire 7. Since the connection between the end of the copper wire body 17 and the wiring terminal 5 is located in a closed structure formed by the combination of the connecting sleeve 2 and the sealing cover 9, there is no need to wrap it with waterproof tape, which avoids the problem that the existing equipotential connector 1 needs to be repeatedly wrapped with waterproof tape to avoid leakage at the connection and ensure the stability of the connection after wiring, which is not only unsightly but also has low connection efficiency.
