Description

Technical Field

[0001] This application relates to the field of terminal blocks, and more particularly to an electronic wire harness terminal block. Background Technology

[0002] Terminal blocks are used to facilitate the connection of wires. They are actually a metal plate encased in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. For example, if two wires need to be connected sometimes and disconnected at other times, they can be connected with terminals and disconnected at any time without having to solder or twist them together, which is convenient and quick.

[0003] Terminal blocks are a type of terminal block that connects single terminals in parallel to form multiple terminals. A terminal block is an insulating component that carries multiple or more sets of mutually insulated terminal assemblies and is used for fixing and supporting components. The function of terminal blocks is to connect the wiring of equipment inside and outside the panel, facilitating signal (current and voltage) transmission. Terminal blocks make wiring neat, maintenance convenient, and connections between long-distance lines reliable, simplifying construction and maintenance.

[0004] In the prior art, the terminal block includes a body and terminals. The body has a wire insertion hole. After the wire harness is inserted into the wire insertion hole, the terminal is tightened to clamp the wire harness in the wire insertion hole. The connection between the terminal and the body is a bolt connection.

[0005] However, when equipment such as substations includes a large number of terminal blocks and a large number of electronic wire harnesses that need to be assembled on the terminal blocks, the workload of manually rotating, loosening and tightening the terminals is very large, and installation and disassembly are inconvenient. Especially during commissioning and maintenance, repeated disassembly and assembly are often required. Frequent twisting of the terminals can easily cause stripping of the threads, and frequent twisting of the terminals can easily damage the anti-rust layer, leading to rust and malfunction, affecting normal use. Summary of the Invention

[0006] To improve the efficiency of installing electronic wire harnesses, this application provides an electronic wire harness terminal block.

[0007] The electronic wire harness terminal block provided in this application adopts the following technical solution:

[0008] An electronic wire harness terminal block includes a base, a conductive sheet, a torsion spring, and a clamping plate. The conductive sheet is fixedly connected to the base, the clamping plate is rotatably connected to the base, one end of the torsion spring is connected to the base, and the other end of the torsion spring is connected to the clamping plate. The conductive sheet and the clamping plate together clamp the electronic wire harness.

[0009] By adopting the above technical solution, the torsion spring enables the clamping plate and the conductive sheet to clamp the electronic wire harness placed on the conductive sheet. When installing the electronic wire harness, it is only necessary to apply force to the clamping plate to control the torsion spring to deform, so that an opening is created between the clamping plate and the conductive sheet for the electronic wire harness to be placed. After the electronic wire harness is placed, the hand force is released, and the torsion spring returns to its deformation and automatically clamps the electronic wire harness. The operation is simple and the installation efficiency is improved.

[0010] Preferably, it also includes a limiting post, which is fixedly connected to the end of the conductive sheet away from the base. The end of the clamping plate facing the conductive sheet is provided with a limiting groove, which is used for the limiting post to be inserted.

[0011] By adopting the above technical solution, the limiting post can easily limit the position of the electronic wire harness. The end of the electronic wire harness can be wound into a loop and placed outside the limiting post, making the connection of the electronic wire harness more stable and less likely to fall off the terminal block due to external pulling. The operation is simple.

[0012] Preferably, the device further includes a mounting plate, an abutment block, and a pressure rod. The base body has a mounting groove for the mounting plate to be embedded in. The end of the mounting plate near the torsion spring is rotatably connected to the groove wall. The rotation axis of the mounting plate is parallel to the rotation axis of the clamping plate. The conductive sheet is fixedly connected to the end of the mounting plate away from the bottom of the mounting groove. The abutment block is connected to the end of the conductive sheet away from the mounting plate. The abutment block has an abutment interface. The axis of the abutment interface is perpendicular to the rotation axis of the mounting plate. One end of the pressure rod is rotatably connected to the base body. The pressure rod is located on the side of the clamping plate away from the mounting plate. The rotation axis of the pressure rod is parallel to the rotation axis of the clamping plate. The length direction of the pressure rod is perpendicular to the rotation axis of the pressure rod. The other end of the pressure rod is embedded in the abutment interface. The end of the pressure rod facing the base body is used to abut against the clamping plate. The clamping plate has a clearance opening for the abutment block to pass through.

[0013] By adopting the above technical solution, rotating the clamping plate causes the torsion spring to deform under force, the clamping plate abuts against the seat, and rotating the pressure rod causes one end of the pressure rod to extend into the abutment interface. The pressure rod limits the position of the clamping plate. When the electronic wire harness is placed on the conductive sheet, the mounting plate is controlled to rotate, causing the pressure rod to fall out of the abutment interface. The torsion spring restores its deformation and automatically controls the rotation of the clamping plate and the conductive sheet to clamp the electronic wire harness together, thereby improving the efficiency of installing the electronic wire harness.

[0014] Preferably, the outer wall of the mounting plate is connected to a pressure block, which is used for the operator to apply force.

[0015] By adopting the above technical solution, when the electronic wire harness is placed on the conductive sheet, pressing the clamping block will automatically clamp the wire harness with the mounting plate, which is simple to operate and improves the installation efficiency of the electronic wire harness.

[0016] Preferably, it also includes a first spring, the bottom of the mounting groove is provided with a placement groove, one end of the first spring is connected to the bottom of the placement groove, and the other end of the first spring is connected to the mounting plate.

[0017] By adopting the above technical solution, the first spring makes the clamping plate and the mounting plate clamp more tightly, making the placement of the electronic wire harness more stable.

[0018] Preferably, it further includes a guide post and a guide block. A retaining ring is coaxially connected to the inner circumference of the placement groove. The retaining ring is coaxially provided with a guide opening. The guide post is slidably embedded in the guide opening. One end of the guide post abuts against the mounting plate. The other end of the guide post is fixedly connected to the guide block. The guide block is slidably embedded in the placement groove. The end of the guide block facing the bottom of the placement groove is provided with a clearance groove. One end of the first spring is connected to the bottom of the clearance groove, and the other end of the first spring is connected to the bottom of the placement groove.

[0019] By adopting the above technical solution, the first spring is easily damaged by the force when it directly abuts against the mounting plate. The guide post abuts against the mounting plate, which can protect the abutting spring.

[0020] Preferably, the device further includes a warning post and a second spring. The groove wall of the placement slot is provided with a warning opening, which extends to the end away from the pressure rod and penetrates the base body. The warning post is slidably embedded in the warning opening, with one end of the warning post abutting against a guide block. The inner wall of the warning opening is provided with an abutting groove, and a protrusion is connected to the outer periphery of the warning post. The second spring is disposed in the abutting groove, with the axis of the second spring parallel to the axis of the warning opening. One end of the second spring is connected to the protrusion, and the other end of the second spring is connected to the groove wall of the abutting groove.

[0021] By adopting the above technical solution, when the clamping plate and the conductive sheet clamp the electronic wire harness, the guide block slides, causing the warning post to slide, reminding the operator to complete the installation. When the torsion spring is damaged after long-term use, the first spring pushes the guide block upward, causing the second spring to push the warning post to move towards the placement slot, reminding the operator that the electronic wire harness is not clamped, thus improving the installation efficiency of the electronic wire harness.

[0022] Preferably, the end of the guide block facing the warning post is provided with a guide surface, and the distance from the guide surface to the retaining ring increases as the distance from the guide surface to the warning opening increases.

[0023] By adopting the above technical solution, the guide surface can be easily controlled by controlling the sliding of the guide block to control the sliding of the warning post, thus making the warning post work stably.

[0024] Preferably, the end of the pressure plate away from the torsion spring is connected to an operating block, which is used for the operator to apply force.

[0025] By adopting the above technical solution, the operating block makes it easy for operators to apply force with their hands and to control the rotation of the clamping plate to remove the electronic wire harness.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The torsion spring causes the clamping plate and the conductive plate to clamp the electronic wire bundle placed on the conductive plate. When installing the electronic wire bundle, it is only necessary to apply force to the clamping plate to control the torsion spring to deform, so that an opening is made between the clamping plate and the conductive plate for the electronic wire bundle to be placed. After the electronic wire bundle is placed, the hand force is released, and the torsion spring returns to its deformation and automatically clamps the electronic wire bundle. The operation is simple and the installation efficiency is improved.

[0028] 2. Rotating the clamping plate causes the torsion spring to deform under force. The clamping plate abuts against the base. Rotating the pressure rod causes one end of the pressure rod to extend into the abutment interface. The pressure rod limits the position of the clamping plate. When the electronic wire harness is placed on the conductive sheet, the mounting plate is rotated to cause the pressure rod to fall out of the abutment interface. The torsion spring returns to its original deformation and automatically controls the rotation of the clamping plate and the conductive sheet to clamp the electronic wire harness together, improving the efficiency of installing the electronic wire harness.

[0029] 3. When the clamping plate and conductive sheet clamp the electronic wire harness, the guide block slides, causing the warning post to slide, reminding the operator to complete the installation. When the torsion spring is damaged after long-term use, the first spring pushes the guide block upward, causing the second spring to push the warning post to move towards the placement slot, reminding the operator that the electronic wire harness is not clamped, thus improving the installation efficiency of the electronic wire harness.
