[0001] This application relates to the field of terminal block technology, for example to a safety terminal block for power engineering that is operable under live conditions. Background Technology

[0002] Currently, wire connectors, also known as terminal blocks, are metal pieces encased in insulating plastic. They have sockets and fastening screws at both ends for quickly connecting or disconnecting wires, avoiding soldering or tangling. For safety, power is typically disconnected before installing wire connectors, and then restored after installation.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] In some emergency situations, power outages can cause significant losses to equipment. Therefore, installing wiring terminals requires live installation, and reducing the risks associated with live wiring becomes an urgent problem to be solved.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a safety connector for power engineering that allows for live-line work, thereby reducing the risk of live wiring and meeting the requirement that equipment can be operated without power interruption.

[0008] In some embodiments, a safety connector for live-line working in electrical engineering includes: an insulating box, a first connecting piece, a second connecting piece, a blocking assembly, and a pressing assembly. The first connecting piece has a first abutting end extending into the insulating box; the second connecting piece has a second abutting end extending into the insulating box; the blocking assembly is partially movably disposed within the insulating box to block the first and second abutting ends, and partially extends through the insulating box to the outside of the insulating box; the pressing assembly is partially movably disposed within the insulating box to push the first and second abutting ends into contact, and partially extends through the insulating box to the outside of the insulating box.

[0009] Optionally, the partition assembly includes a sliding block and a pull rod. The sliding block is slidably connected to the inner wall of the insulating box and is located between the first abutment end and the second abutment end to isolate the first abutment end and the second abutment end; the pull rod is slidably connected to a sliding hole in the insulating box, with one end connected to the sliding block and the other end extending outside the insulating box.

[0010] Optionally, the inner wall of the insulating box is provided with a groove corresponding to the sliding block, the sliding hole is connected to the groove, and the sliding block can be slidably embedded in the groove to block the sliding hole.

[0011] Optionally, the end of the pull rod connected to the sliding block gradually narrows to form a breakable section.

[0012] Optionally, the pressing assembly includes a pressure plate and a pressure rod. The pressure plate is movably disposed within the insulating box, located on the side of the second connecting piece facing away from the first connecting piece; one end of the pressure rod is fixedly connected to the pressure plate, and the other end extends through a threaded hole in the insulating box to the outside of the insulating box.

[0013] Optionally, the free end of the pressure bar is provided with a thread that engages with the threaded hole.

[0014] Optionally, a locking block is provided on the inner wall of the insulating box, and the locking block engages with the slot on the first connecting piece.

[0015] Optionally, a limiting block is provided on the inner wall of the insulating box, and the limiting block abuts against the second connecting piece to prevent the second connecting piece from coming out of the insulating box.

[0016] Optionally, the first connecting piece is provided with a connecting hole.

[0017] Optionally, the pressing assembly is made of an insulating material.

[0018] The safety connector for live-line work provided in this disclosure can achieve the following technical effects:

[0019] Connect the first connecting piece to the location where wiring is required. Pull the portion of the isolation assembly outside the insulating box, causing the portion inside the insulating box to move within the box. This disengages the isolation assembly from the first and second connecting pieces, releasing the separation between the first and second abutting ends. Then press the pressing assembly, causing it to slide relative to the insulating box and press the second abutting end towards the first abutting end until they abut. The first and second connecting pieces then come into contact and become energized, completing the live installation. Since both the first and second abutting ends abut within the insulating box, the risk of external discharge is reduced, thus lowering the risk of live wiring and meeting the requirement of not needing to shut down the equipment.

[0033] Unless otherwise stated, the term "multiple" means two or more.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0035] Combination Figures 1-5As shown, this embodiment of the present disclosure provides a safety connector for live-line work in electrical engineering, comprising: an insulating box 100, a first connecting piece 200, a second connecting piece 300, a blocking assembly 400, and a pressing assembly 500. The first connecting piece 200 has a first abutting end 210 extending into the insulating box 100; the second connecting piece 300 has a second abutting end 310 extending into the insulating box 100; the blocking assembly 400 is partially movably disposed within the insulating box 100 to block the first abutting end 210 and the second abutting end 310, and partially extends through the insulating box 100 to the outside of the insulating box 100; the pressing assembly 500 is partially movably disposed within the insulating box 100 to push the first abutting end 210 and the second abutting end 310 to abut against each other, and partially extends through the insulating box 100 to the outside of the insulating box 100.

[0036] Using the live-line working safety connector provided in this embodiment, the first connecting piece 200 is connected to the position where wiring is required. The portion of the isolation assembly 400 outside the insulating box 100 is pulled, thereby causing the portion of the isolation assembly 400 inside the insulating box 100 to move within the insulating box 100. This disengages the isolation assembly 400 from the first connecting piece 200 and the second connecting piece 300, releasing the separation between the first abutment end 210 and the second abutment end 310. Then, the pressing assembly 500 is pressed, causing it to slide relative to the insulating box 100. The pressing assembly 500 presses the second abutment end 310 towards the first abutment end 210 until the first abutment end 210 and the second abutment end 310 abut against each other. The first connecting piece 200 and the second connecting piece 300 then come into contact with each other to conduct electricity, completing the live installation. Both the first contact end 210 and the second contact end 310 are in contact within the insulating box 100, reducing the risk of external discharge and thus reducing the risk of live wiring, meeting the requirement that the equipment does not need to be powered off.

[0037] Combination Figure 3 and Figure 4 As shown, optionally, the end of the second connecting piece 300 facing away from the insulating box 100 is provided with a connecting piece 320, which is used to clamp the wire. In this way, the wire can be clamped by the connecting piece 320, so that the connecting piece 320 abuts against the wire core inside the wire, making the operation more convenient.

[0038] Specifically, the connector 320 is coiled. This makes it easier for the internal wire core to be inserted into the connector 320.

[0039] Optionally, the first connecting piece 200 is provided with a connecting hole 201. In this way, the first connecting piece 200 can be fixed at the position where wiring is required through the connecting hole 201 and screws, resulting in a more secure connection and easier installation.

[0040] Optionally, the partition assembly 400 includes a sliding block 410 and a pull rod 420. The sliding block 410 is slidably connected to the inner wall of the insulating box 100 and is located between the first abutment end 210 and the second abutment end 310 to isolate the first abutment end 210 and the second abutment end 310. The pull rod 420 is slidably connected to the sliding hole 101 of the insulating box 100, with one end connected to the sliding block 410 and the other end extending outside the insulating box 100. In this way, after the first connecting piece 200 is installed and fixed, pulling the pull rod 420 causes the sliding block 410 to move within the insulating box 100 until the sliding block 410 disengages from the contact between the first connecting piece 200 and the second connecting piece 300, releasing the restriction of the first abutment end 210 and the second abutment end 310 abutting, making the operation more convenient.

[0041] Optionally, the inner wall of the insulation box 100 is provided with a groove 102 corresponding to the sliding block 410. The sliding hole 101 communicates with the groove 102, and the sliding block 410 can be slidably embedded in the groove 102 to seal the sliding hole 101. In this way, the sliding block 410 can slide into the groove 102, and the groove 102 limits and fixes the sliding block 410, reducing the risk of disorderly shaking of the sliding block 410 inside the insulation box 100. Moreover, the sliding block 410 can seal the sliding hole 101, improving the sealing effect of the insulation box 100.

[0042] Optionally, an exhaust hole 103 is provided on the inner sidewall of the groove 102. In this way, the sliding block 410 can be vented through the exhaust hole 103 when it slides into the groove 102, thereby reducing the resistance of the sliding block 410 sliding into the groove 102.

[0043] Optionally, both the sliding block 410 and the pull rod 420 are provided in multiple sets, preferably two sets, with the two sets of sliding blocks 410 disposed on opposite sides of the second connecting piece 300. In this way, by setting the two sliding blocks 410 between the first connecting piece 200 and the second connecting piece 300, the stability of the partition is relatively good, and the two sets of sliding blocks 410 slide in opposite directions, reducing the risk of mutual interference.

[0044] Optionally, each groove 102 has two guide bars 110 at its groove edge, and the guide bars 110 are slidably connected to the sliding block 410. In this way, the guide bars 110 provide power for the sliding block 410 to slide, guide the sliding block 410 to slide into the groove 102, and reduce the risk of the sliding block 410 deviating.

[0045] Optionally, the end of the pull rod 420 connected to the sliding block 410 gradually narrows to form a breakable portion 421. In this way, after the sliding block 410 is pulled to the designated position, the pull rod 420 can be rotated, causing the breakable portion 421 of the pull rod 420 to break, reducing the risk of interference caused by residual pull rod 420, and improving the overall integrity of the insulating box 100.

[0046] Optionally, the pressing assembly 500 includes a pressure plate 510 and a pressure rod 520. The pressure plate 510 is movably disposed within the insulating box 100, located on the side of the second connecting piece 300 facing away from the first connecting piece 200. One end of the pressure rod 520 is fixedly connected to the pressure plate 510, and the other end extends through the threaded hole 104 of the insulating box 100 to the outside of the insulating box 100. In this way, pressing the pressure rod 520 moves the pressure plate 510 toward the second connecting piece 300, pressing the second abutting end 310 of the second connecting piece 300 to abut against the first abutting end 210, thus completing the connection. The operation is relatively convenient and the risk is relatively low.

[0047] Specifically, the pressure plate 510 has a circular plate structure. In this way, the contact area between the pressure plate 510 and the second connecting piece 300 is relatively large, and the pressing stability is relatively high.

[0048] Optionally, the free end of the pressure rod 520 is provided with a thread that engages with the threaded hole 104. In this way, the front section can press the pressure rod 520, causing the pressure rod 520 and the threaded hole 104 to slide relative to each other, resulting in a faster pressing speed and higher efficiency. The thread of the rear pressure rod 520 rotates and engages with the threaded hole 104, resulting in relatively greater pressing strength and support force, and better stability.

[0049] Optionally, the length of the thread is less than the length of the pressure rod 520, and the length of the thread is greater than the length of the threaded hole 104. In this way, the relatively short length of the thread allows the pressure rod 520 to press the first abutment end 210 and the second abutment end 310 at a faster speed.

[0050] Optionally, the free end of the pressure rod 520 is provided with a slot. This facilitates the rotation of the pressure rod 520.

[0051] Optionally, a locking block 120 is provided on the inner wall of the insulating box 100, and the locking block 120 engages with the locking groove 202 on the first connecting piece 200. In this way, the engagement of the locking block 120 and the locking groove 202 restricts the sliding of the first connecting piece 200 relative to the insulating box 100.

[0052] Optionally, both the card block 120 and the card slot 202 have multiple slots. This results in a relatively large number of restrictive positions and a relatively strong restrictive force.

[0053] Combination Figure 5 As shown, optionally, a limiting block 130 is provided on the inner sidewall of the insulating box 100. The limiting block 130 abuts against the second connecting piece 300 to prevent the second connecting piece 300 from coming out of the insulating box 100. In this way, the second connecting piece 300 is prevented from coming out of the insulating box 100, and the stability is relatively high.

[0054] Optionally, the second connecting piece 300 has protrusions 330 on both sides of the second abutting end 310. In this way, the protrusions 330 cooperate with the limiting block 130 to prevent the second connecting piece 300 from coming out of the insulating box 100, thus achieving relatively high stability.

[0055] Optionally, the isolation component 400 is made of insulating material. This reduces the risk of external discharge.

[0056] Optionally, the pressing assembly 500 is made of insulating material. This reduces the risk of external discharge.

[0057] Understandably, the insulation material can be cross-linked polyethylene (XLPE).
