Description

Technical Field

[0001] The utility model relates to the technical field of electric wire connection, in particular to a power line connection device and a conductive device. Background Art

[0002] In some application fields of power equipment, the connection state between two power lines needs to be designed to be switchable, capable of switching between an open circuit state and an on circuit state.

[0003] In the prior art, there are mainly two types of structures for connecting two power cords. The first is a threaded connection structure, which mainly includes two connection cylinders. The two connection cylinders can be threadedly connected. When in use, one of the connection cylinders is sleeved on one of the power cords, and the other connection cylinder is sleeved on the other power cord. The two connection cylinders are then threadedly connected to make the two power cords contact and conduct. However, the threaded connection structure requires the two connection cylinders to be rotated relative to each other to achieve the threaded connection, which causes the power cord to rotate at too large an angle and is subjected to excessive torque. The threaded connection structure has a small application range and is generally only used on power cords with longer lengths. The second is a clip-on structure. However, the current clip-on structure often automatically unlocks, causing the two power cords to separate.

[0004] Therefore, there is an urgent need for a power line connection device and a conductive device to solve the above problems. Utility Model Content

[0045] like Figures 1 to 7 As shown, this embodiment provides a power cord connection device, which includes a first connection seat 1, a second connection seat 3, a rotating shaft 5, a clamping plate 7 and a torsion spring 6. The first connection seat 1 is provided with a first terminal 2; the second connection seat 3 is provided with a second terminal 4, the first connection seat 1 and the second connection seat 3 are detachably connected, and the second connection seat 3 is provided with a clamping groove 31; the rotating shaft 5 is arranged on the first connection seat 1; the clamping plate 7 is rotatably sleeved on the periphery of the rotating shaft 5; the torsion spring 6 is sleeved on the periphery of the rotating shaft 5, and the two ends of the torsion spring 6 are respectively connected or abutted against the first connection seat 1 and the clamping plate 7. When the first connection seat 1 is connected to the second connection seat 3, the torsion spring 6 drives the clamping plate 7 to clamp into the clamping groove 31, locks the first connection seat 1 and the second connection seat 3 and keeps the second terminal 4 in contact with the first terminal 2.

[0046] Specifically, when two power cords 100 need to be connected, the first connecting seat 1 and the second connecting seat 3 are connected, and the card plate 7 is driven by the torsion spring 6 so that the card plate 7 is engaged in the card slot 31, thereby locking the first connecting seat 1 and the second connecting seat 3 to ensure that the first terminal 2 and the second terminal 4 can be in stable contact, thereby ensuring the connection stability of the two power cords 100.

[0047] When the two power cords 100 need to be separated, the user can press the card plate 7 with one hand to disengage the card plate 7 from the card slot 31 to achieve unlocking, thereby separating the first connecting socket 1 and the second connecting socket 3.

[0048] In this embodiment, there are three first terminals 2 and three second terminals 4. The three first terminals 2 are respectively connected to the live wire, neutral wire and ground wire of one power line 100, and the three second terminals 4 are respectively connected to the live wire, neutral wire and ground wire of another power line 100.

[0049] In this embodiment, the two ends of the torsion spring 6 are respectively connected to the first connection seat 1 and the clamping plate 7, and the torsion spring 6 uses elastic thrust to push the clamping plate 7 to rotate around the rotation shaft 5, so that one end of the clamping plate 7 is clamped in the clamping slot 31. In some other embodiments, the two ends of the torsion spring 6 are respectively connected to the first connection seat 1 and the clamping plate 7, and the torsion spring 6 uses elastic tension to pull the clamping plate 7 to rotate around the rotation shaft 5, so that one end of the clamping plate 7 is clamped in the clamping slot 31.

[0050] Optionally, the outer wall of the first connecting seat 1 is provided with a first mounting hole 16, the middle part of the clamping plate 7 is provided with a second mounting hole 73, and the rotating shaft 5 passes through the first mounting hole 16 and the second mounting hole 73. When the torsion spring 6 or the clamping plate 7 needs to be replaced, the rotating shaft 5 can be pulled out from the first mounting hole 16 and the second mounting hole 73.

[0051] Optionally, the first connecting seat 1 is provided with two limit platforms 11, and the two limit platforms 11 are arranged at intervals along the axial direction of the rotating shaft 5. The torsion spring 6 is located between the two limit platforms 11. The two limit platforms 11 are used to limit the axial movement of the torsion spring 6 along the rotating shaft 5 to prevent the torsion spring 6 from axially moving along the rotating shaft 5.

[0052] Optionally, the clamping plate 7 includes a clamping end 71 and a pushing end 72, the clamping end 71 is located on the side of the rotating shaft 5 close to the slot 31, the clamping end 71 is used to clamp into the slot 31, the pushing end 72 and the limit platform 11 are both located on the side of the rotating shaft 5 away from the slot 31, one end of the torsion spring 6 abuts against the pushing end 72, and the other end of the torsion spring 6 falls between the two limit platforms 11 and abuts against the first connecting seat 1.

[0053] The two limit platforms 11 limit the position of one end of the torsion spring 6 that abuts the first connecting seat 1 to prevent the torsion spring 6 from moving axially along the rotating shaft 5; when the first connecting seat 1 and the second connecting seat 3 need to be separated, the pushing end 72 is pressed down, and due to the lever principle, the clamping end 71 is disengaged from the clamping slot 31, and the first connecting seat 1 and the second connecting seat 3 can be easily separated.

[0054] Optionally, a contact groove is provided on a side of the push end 72 facing the first connecting seat 1 , and an end of the torsion spring 6 contacts the contact groove, thereby preventing the torsion spring 6 from moving axially along the rotating shaft 5 .

[0055] Optionally, the surface of the pushing end 72 is provided with a pattern to increase the friction coefficient of the surface of the pushing end 72 to facilitate the user to push the pushing end 72.

[0056] Optionally, the card slot 31 is an inclined slot, and the card connection end 71 is obliquely inserted into the card slot 31 .

[0057] The card plate 7 is rotatably connected to the card slot 31. In this embodiment, the card slot 31 is set as an inclined slot. When the first connecting seat 1 and the second connecting seat 3 are assembled in place, the user loosens the pushing end 72. Due to the elastic thrust of the torsion spring 6, the card plate 7 rotates around the rotating shaft 5, and the card end 71 is inserted into the card slot 31 along the inclined surface of the card slot 31. The card end 71 is in close contact with the inclined surface of the card slot 31 to prevent a gap from appearing between the card end 71 and the inclined surface, so as to ensure the connection stability of the first connecting seat 1 and the second connecting seat 3.

[0058] Optionally, an inclined sliding surface 74 is provided on the side of the clamping end 71 facing the first connecting seat 1. When the second connecting seat 3 is inserted into the first connecting seat 1, if the user applies less pressure to the pushing end 72, the inclined sliding surface 74 abuts against and slides over the outer surface of the second connecting seat 3, thereby preventing the outer surface of the second connecting seat 3 from being scratched. If the user can apply enough pressure to the pushing end 72, the inclined sliding surface 74 will not contact the outer surface of the second connecting seat 3, thereby also preventing the outer surface of the second connecting seat 3 from being scratched.

[0059] In this embodiment, the first terminal 2 is a female terminal, the second terminal 4 is a male terminal, the first connecting seat 1 includes an inner shell 12 and an outer shell 13 arranged on the periphery of the inner shell 12, a limiting groove 14 is formed between the inner shell 12 and the outer shell 13, the first terminal 2 is inserted into the inner shell 12, the inner shell 12 is provided with a connecting opening 121, the second terminal 4 is inserted into the second connecting seat 3, when the peripheral wall of the second connecting seat 3 is embedded in the limiting groove 14, the second terminal 4 is inserted into the first terminal 2 through the connecting opening 121.

[0060] The limiting groove 14 limits and guides the peripheral wall of the second connection seat 3 to ensure that the second terminal 4 can be aligned with the connection opening 121, and because the first terminal 2 is inserted into the inner shell 12, it can ensure that the second terminal 4 can be inserted into the first terminal 2 after passing through the connection opening 121.

[0061] Optionally, a guide groove 131 is provided on the inner wall of the outer shell 13 , and a guide wall 32 is provided on the outside of the second connecting seat 3 . The guide wall 32 is slidably inserted in the guide groove 131 to guide the second connecting seat 3 .

[0062] Optionally, the first connecting seat 1 is provided with a supporting platform 15, which is located on one side of the notch of the limiting groove 14. When the first connecting seat 1 is separated from the second connecting seat 3, the supporting platform 15 abuts against the clamping end 71 to prevent the clamping end 71 from blocking the notch of the limiting groove 14.

[0063] Optionally, one of the outer wall of the first terminal 2 and the inner wall of the inner shell 12 is provided with a positioning groove 21, and the other is provided with a positioning block, which is embedded in the positioning groove 21 to limit the female terminal from being separated from the inner shell 12.

[0064] In this embodiment, the outer wall of the first terminal 2 is provided with a positioning groove 21, and the inner wall of the inner shell 12 is provided with a positioning block.
