Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a test lead connector. Background Technology

[0002] In daily routine inspections, tests, troubleshooting, and high-voltage testing of distribution network automation and relay protection, temporary shorting of secondary control and signal circuits using test jumpers is necessary. Currently, the main methods are direct wiring or clamping the test leads for shorting. However, direct wiring often leads to wiring difficulties due to the numerous existing connections in the terminal holes, resulting in screw damage and loosening. Using clamps or pliers for fixing is not only inefficient but also carries high operational risks.

[0003] To address the above issues, there is an urgent need for a device that can quickly and stably fix the test leads. Summary of the Invention

[0004] The purpose of this invention is to provide a test lead connection terminal that can quickly and securely connect test leads, improve work efficiency, and reduce operational risks.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Test lead connection terminals, including:

[0007] The housing has an internal mounting space, and a connection hole is provided on the side wall of the housing, the connection hole communicating with the mounting space.

[0008] The clamping mechanism includes a clamping drive assembly and two clamping plates disposed in the mounting space. One end of the test line passes through the connection hole and is placed between the two clamping plates. The clamping drive assembly is used to drive the two clamping plates to clamp the test line.

[0009] Preferably, the clamping drive assembly includes a clamping button and a lever assembly. The clamping button is mounted on the housing and partially placed within the mounting space. One end of the lever assembly is connected to the clamping button, and the other end is driven to connect to the two clamping plates. Pressing the clamping button drives the lever assembly to move, causing the two clamping plates to move away to place the test wire. Releasing the clamping button drives the lever assembly to move, causing the two clamping plates to move closer together to clamp the test wire.

[0010] Preferably, the rod assembly includes two symmetrically arranged connecting rods and two rotating rods. The rotating rods include a horizontal part and an inclined part connected to each other. One end of the connecting rod is hinged to the clamping button, and the other end is hinged to the horizontal part of the rotating rod. The end of the inclined part of the rotating rod is hinged to the clamping plate, and the middle position of the inclined part is rotatably connected to the inner wall of the housing through a fixed shaft.

[0011] Preferably, the end of the horizontal part of the rotating rod is provided with teeth to assist rotation, and the teeth of the two horizontal parts mesh with each other; or, the end of the horizontal part of the rotating rod can also be provided as an arc surface, and the arc surfaces of the two horizontal parts are tangent to each other.

[0012] Preferably, the clamping button is an I-shaped button, and the housing has a first through hole. The clamping button is sleeved on the housing through the first through hole. The clamping drive assembly also includes a clamping return spring. The upper surfaces of both sides of the bottom of the clamping button are provided with grooves. One end of the clamping return spring is fixedly connected to the end face of the groove, and the other end is fixed to the inner wall of the housing.

[0013] Preferably, the test lead connection terminal further includes a power-off mechanism, which includes a disconnection drive component and a conductive plate disposed in the installation space. One end of the conductive plate is electrically connected to an external power connection device. One end of the test lead passes through the connection hole and the clamp and contacts and conducts electricity with the other end of the conductive plate. The disconnection drive component can drive the conductive plate to move so that the other end of the conductive plate is disconnected from one end of the test lead.

[0014] Preferably, the conductive plate includes an arc-shaped portion and a connecting portion connected together. The arc-shaped portion of the conductive plate contacts one end of the test line, and the connecting portion of the conductive plate is connected to an external power connection device. The connection between the arc-shaped portion and the connecting portion of the conductive plate is fixed at the opening of the housing, and the connecting portion of the conductive plate is on the outside of the housing. The disconnection drive assembly can drive the arc-shaped portion of the conductive plate to bend and deform, so that the arc-shaped portion of the conductive plate is disconnected from one end of the test line.

[0015] Preferably, the disconnect drive assembly includes a disconnect button and a slanted panel. The disconnect button is mounted on the housing and partially placed within the installation space. One end of the slanted panel is fixedly connected to the disconnect button, and the other end of the slanted panel contacts the arc-shaped portion of the conductive plate. The cross-sectional width of the slanted panel gradually increases from bottom to top. Pressing the disconnect button causes the slanted panel to move, and the slanted panel drives the arc-shaped portion of the conductive plate to bend and deform, thereby disconnecting the arc-shaped portion of the conductive plate from one end of the test lead.

[0016] Preferably, the disconnect button has protrusions on both sides of its bottom, and the housing has a second through hole. The disconnect button is sleeved on the housing through the second through hole, and the bottom of the disconnect button is disposed inside the housing.

[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] In daily routine inspections, tests, troubleshooting, and high-voltage testing of distribution network automation and relay protection, temporary shorting of secondary control and signal circuits using test jumpers is necessary. Currently, the main methods are direct wiring or clamping the test leads for shorting. However, direct wiring often leads to wiring difficulties due to the numerous existing connections in the terminal holes, resulting in screw damage and loosening. Using clamps or pliers for fixing is not only inefficient but also carries high operational risks.

[0038] To address the aforementioned problems, this embodiment provides a convenient and quick test lead connection terminal. For example... Figure 1 As shown, the test lead connection terminal includes a housing 1 and a clamping mechanism. The housing 1 has a connection hole 11 on its side wall and an installation space inside, which communicates with the connection hole 11. Specifically, as shown... Figure 2 and Figure 3 As shown, the clamping mechanism is set in the installation space. The clamping mechanism includes a clamping drive assembly and two clamping plates 21. In use, one end of the test wire is passed through the connection hole 11 and placed between the two clamping plates 21. The clamping drive assembly drives the two clamping plates 21 to move closer together and clamp the test wire.

[0039] like Figure 4 As shown, the clamping surfaces of the two clamping plates 21 can be arc-shaped, which can better fit the circular structure of the test line, thereby preventing loosening and achieving stable clamping.

[0040] Preferably, insulating elastic rubber pads are provided on the end faces of the arc-shaped surfaces of the two clamps 21 to prevent electric shock during operation.

[0041] In this embodiment, the operator can use the clamping drive assembly to drive the two clamping plates 21 to clamp the test wires to quickly connect and fix the test wires. The operation is convenient, the work efficiency is greatly improved, the operation risk is significantly reduced, and a strong guarantee is provided for the operation of the equipment.

[0042] Optionally, such as Figure 3 , Figure 4 As shown, the clamping drive assembly includes a clamping button 22 and a rod assembly. The clamping button 22 is mounted on the housing 1 and partially placed within the installation space. One end of the rod assembly is connected to the clamping button 22, and the other end drives and connects to two clamping plates 21. In use, pressing the clamping button 22 drives the rod assembly to move. When the rod assembly moves the two clamping plates 21 away, it releases the test wire; when the rod assembly moves the two clamping plates 21 closer, it clamps the test wire.

[0043] like Figure 3 , Figure 4As shown, the clamping button 22 is an I-shaped button. A first through hole 12 is provided on the housing 1, through which the clamping button 22 is fitted onto the housing 1. Grooves 221 are provided on the upper surfaces of both sides of the bottom of the clamping button 22. Correspondingly, the clamping drive assembly of this embodiment also includes a clamping return spring 25. One end of the clamping return spring 25 is fixedly connected to the end face of the groove 221 at the bottom of the clamping button 22, and the other end is fixed to the inner wall of the housing 1. When the clamping button 22 is not pressed, the clamping return spring 25 is in its natural state, and the two clamping plates 21 are close together. When the clamping button 22 is pressed, the clamping return spring 25 is in a stretched state, the rod assembly moves, and the two clamping plates 21 move away. At this time, the clamping button 22 is released, and the clamping return spring 25 returns to its natural state under its own elastic force, driving the clamping button 22 back to its initial position. In this embodiment, by setting the clamping return spring 25, the reset process is made simpler and faster, and the structure is easy to implement.

[0044] In this embodiment, two grooves 221 are provided, and the two grooves 221 are symmetrically distributed on both sides of the bottom of the clamping button 22. Two clamping reset springs 25 are provided, and each clamping reset spring 25 is placed in one groove 221. It can be understood that multiple clamping reset springs 25 can also be provided, and multiple clamping reset springs 25 are provided in each groove 221 to make the reset process more stable.

[0045] Preferably, the housing 1, the clamping button 22, and the clamping return spring 25 are all made of insulating material.

[0046] Optionally, such as Figure 4 , Figure 5 As shown, the rod assembly may include two symmetrically arranged connecting rods 23 and two rotating rods 24. To better move the two clamping plates 21 closer or further apart, the rotating rods 24 have a connected horizontal portion 241 and an inclined portion 242. One end of the connecting rod 23 is hinged to the clamping button 22, and the other end is hinged to the horizontal portion 241 of the rotating rod 24. The inclined portion 242 of the rotating rod 24 is hinged to the clamping plate 21. To make the rotation process more stable, the middle position of the inclined portion 242 of the rotating rod 24 is rotatably connected to the inner wall of the housing 1 through a fixed shaft 243. In the initial state, both connecting rods 23 are at their highest positions, and the horizontal portion 241 of the rotating rod is at the same horizontal position. When the clamping button 22 is pressed, the clamping button 22 moves downward, causing the connecting rod 23 to move downward. The connecting rod 23 then drives the horizontal portion 241 of the rotating rod 24 to rotate, and the inclined portion 242 of the rotating rod 24 rotates in the opposite direction, causing the clamping plate 21 to move away. When the clamping button 22 is released, the clamping button 22 returns to its initial position, causing the connecting rod 23 to move upward and the rotating rod 24 to rotate, restoring the initial state and causing the two clamping plates 21 to gradually move closer together. In this embodiment, the rod assembly has a simple and stable structure, and the structure of the rod assembly is easy to implement.

[0047] Preferably, both the connecting rod 23 and the rotating rod 24 are made of insulating material.

[0048] like Figure 5 As shown, in this embodiment, an auxiliary rotation tooth 244 is provided at the end of the horizontal part 241 of the rotating rod, and the teeth 244 of the two horizontal parts 241 mesh with each other. When the end of the horizontal part 241 of the rotating rod 24 is pressed against the rotating part, the rotation is smooth. In other embodiments, the end of the horizontal part 241 of the rotating rod 24 can also be set as an arc surface, and the arc surfaces of the two horizontal parts 241 are tangent to each other, so that the ends are in full contact during the rotation process, making the rotation process smooth.

[0049] Preferably, such as Figure 3 , Figure 4 As shown, the installation space is equipped with two slide rails 4, which are located at the upper and lower ends of the connecting hole, as follows. Figure 7 As shown, the upper and lower ends of the clamping plate 21 are provided with sliders 6. The slide rail 4 is slidably connected to the two clamping plates 21 through the sliders 6, so that the two clamping plates 21 can move smoothly in a fixed horizontal position, and the sliding directions of the two clamping plates 21 on the slide rail 4 are opposite.

[0050] Preferably, such as Figure 3 , Figure 4 As shown, auxiliary rods 5 are hinged to the side of the two clamping plates 21 near the housing 1. The end of the auxiliary rods 5 away from the clamping plates 21 is rotatably connected to the inner wall of the housing 1, thereby better limiting the slide rail 4.

[0051] In this embodiment, when the clamping button 22 is not pressed, the clamping return spring 25 is in its natural state, the two connecting rods 23 are at their highest positions, the horizontal portion 241 of the rotating rod 24 is at the same horizontal position, and the two clamping plates 21 are close together. When using the clamping mechanism, pressing the clamping button 22 stretches the clamping return spring 25, causing the clamping button 22 to move downwards, which in turn moves the connecting rod 23 downwards. The connecting rod 23 then drives the horizontal portion 241 of the rotating rod 24 to rotate, and the inclined portion 242 of the rotating rod 24 rotates in the opposite direction, causing the clamping plates 21 to move away from each other. After one end of the test wire is passed through the connecting hole 11 and placed between the two clamping plates 21, the clamping button 22 is released. The clamping return spring 25 returns to its natural state under its own elastic force, causing the clamping button 22 to return to its initial position, which in turn causes the connecting rod 23 to move upwards and the rotating rod 24 to rotate, returning to the initial state. This causes the two clamping plates 21 to gradually move closer together, thereby stably clamping the test wire. This structure makes the operation of this embodiment simple and risk-free.

[0052] Optionally, in this embodiment, a plurality of connection holes 11 are provided on the side wall of the housing 1, and the plurality of connection holes 11 are equally spaced, with a clamping mechanism correspondingly provided in each connection hole 11. By providing multiple clamping mechanisms, multiple test lines can be tested simultaneously, thereby significantly improving efficiency.

[0053] Example 2

[0054] This embodiment provides a test lead connection terminal, which adds a power-off mechanism to the first embodiment to perform a power-off test on the test lead, such as... Figure 7 As shown, the power-off mechanism includes a disconnection drive assembly and a conductive plate 31 disposed within the installation space. One end of the conductive plate 31 is electrically connected to an external power connection device, such as... Figure 3 , Figure 4 , Figure 7 As shown, one end of the test lead passes through the connection hole 11 and the clamp 21, and contacts and conducts electricity with the other end of the conductive plate 31. In use, disconnecting the drive assembly can drive the conductive plate 31 to move, causing the other end of the conductive plate 31 to disconnect from one end of the test lead, thus achieving the purpose of power disconnection. This is simple, quick, and without operational risks.

[0055] Optionally, such as Figure 7 and Figure 8 As shown, the disconnect drive assembly includes a disconnect button 32 and a slanted panel 33. A second through-hole 13 is provided on the housing 1. The disconnect button 32 is fitted onto the housing 1 through the second through-hole 13. The cross-sectional width of the slanted panel 33 gradually increases from bottom to top. One end of the slanted panel 33 is fixedly connected to the disconnect button 32, and the other end contacts the conductive plate 31. When power disconnection is required, pressing the disconnect button 32 causes the slanted panel 33 to move downwards. Due to the large cross-sectional width at the upper end of the slanted panel 33, pressure is applied to the conductive plate 31, driving the conductive plate 31 to move and thus disconnecting it from one end of the test lead, achieving the purpose of power disconnection. The operation is simple and risk-free.

[0056] Optionally, the inclined panel 33 and the disconnect button 32 are both made of insulating materials, and the conductive plate 31 is made of materials such as copper, aluminum, and alloys that have conductive properties and elasticity.

[0057] Specifically, such as Figure 7 As shown, the conductive plate 31 includes an arc-shaped portion 311 and a connecting portion 312 connected to each other. In the working state, the arc-shaped portion 311 of the conductive plate 31 is in contact with the test line, and the connecting portion 312 of the conductive plate 31 is connected to an external power supply device. Through the connection with the external power supply device, the conductive plate 31 and the test line are energized.

[0058] Specifically, in this embodiment, such as Figure 7 , Figure 8As shown, the connection between the arc-shaped portion 311 of the conductive plate 31 and the connecting portion 312 is fixed at the opening of the housing 1, and the connecting portion 312 extends to the outside of the housing 1. In use, when the disconnect button 32 is pressed, the inclined plate 33 moves down. Since the upper cross-sectional width of the inclined plate 33 is large, it can exert pressure on the conductive plate 31. Since the conductive plate 31 is fixed to the housing 1 and the conductive plate 31 is elastic, the arc-shaped portion 311 of the conductive plate 31 will bend, thereby disconnecting from one end of the test lead.

[0059] Preferably, in this embodiment, the end of the connecting portion 312 of the conductive plate 31 is configured as a claw shape. In other embodiments, the end of the connecting portion 312 may be configured as other shapes that facilitate the connection of the power connection device.

[0060] Optionally, such as Figure 7 , Figure 8 As shown, the disconnect button 32 has protrusions on both sides of its bottom, and its bottom is located within the installation space. The disconnect drive assembly also includes a disconnect reset spring 34. One end of the disconnect reset spring 34 is fixedly connected to the upper surface of the protrusions on both sides of the bottom of the disconnect button 32, and the other end is fixed to the inner wall of the housing 1. When the disconnect button 32 is not pressed, the disconnect reset spring 34 is in its natural state, and the inclined panel 33 is in contact with the conductive plate 31. When the disconnect button 32 is pressed, the disconnect reset spring 34 is in a stretched state. When the disconnect button 32 is released, the disconnect reset spring 34 returns to its original state under its own elastic force, driving the disconnect button 32 and the inclined panel 33 back to their initial positions. During the process of the inclined panel 33 returning to its initial position, the pressure acting on the arc-shaped part 311 of the conductive plate 31 gradually decreases to zero. The conductive plate 31 returns to its original position under its own elastic force, maintaining contact with the test lead and restoring the energized state. This embodiment makes the reset process simple, quick, and easy to implement by setting the disconnect reset spring 34.

[0061] In this embodiment, there are two disconnect reset springs 34, distributed on the upper surface of the protrusions on both sides of the bottom of the disconnect button 32. It can be understood that multiple disconnect reset springs 34 can be provided, with multiple disconnect reset springs 34 provided on the upper surface of each protrusion of the disconnect button 32, so as to make the reset process more stable.

[0062] In this embodiment, when power needs to be cut off, pressing the disconnect button 32 stretches the disconnect reset spring 34, and the disconnect button 32 moves downward. The inclined panel 33 moves downward accordingly. Because the upper section of the inclined panel 33 has a large width, it can exert pressure on the conductive plate 31. Since the conductive plate 31 is fixed to the housing 1 and has elasticity, the arc-shaped portion 311 of the conductive plate 31 bends, thus disconnecting from one end of the test lead. When power needs to be restored, releasing the disconnect button 32 causes the disconnect reset spring 34 to return to its natural state under its own elastic force, driving the disconnect button 32 and the inclined panel 33 back to their initial positions. During the process of the inclined panel 33 returning to its initial position, the pressure acting on the arc-shaped portion 311 of the conductive plate 31 gradually decreases to zero. The conductive plate 31 returns to its original position under its own elastic force, maintaining contact with the test lead and restoring power. The power-off mechanism in this embodiment simplifies the power-off process and eliminates operational risks.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
