Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of terminal strip wiring test, and particularly relates to a terminal strip wiring test device. BACKGROUND

[0002] A terminal strip is usually arranged on a control cabinet of a power system, and the terminal strip has a plurality of wiring terminals insulated from each other, and the control cabinet is in conduction with an external device through the wiring terminals; when wiring test of the terminal strip is performed, a test wire joint needs to be inserted into different wiring terminals by a test personnel, and in this process, wiring between the test wire joint and the wiring terminals is not tight due to operation error of the test personnel, and thus the test result is inaccurate. SUMMARY

[0003] Therefore, it is necessary to provide a terminal strip wiring test device in view of the problem that wiring between a test wire joint and a wiring terminal is not tight due to operation error of a test personnel, and thus a test result is inaccurate.

[0004] The technical scheme is as follows:

[0005] One embodiment provides a terminal strip wiring test device, which comprises:

[0006] A first clamping mechanism, the first clamping mechanism has a first holding end and an electrical connection end arranged oppositely, the electrical connection end is provided with an electrical connection piece, the electrical connection piece is used for being matched with a wiring terminal, and the first clamping mechanism is provided with a first rotating part;

[0007] A second clamping mechanism, the second clamping mechanism has a second holding end and a clamping end arranged oppositely, the second clamping mechanism is provided with a second rotating part, and the second rotating part is rotatably connected with the first rotating part, so that the electrical connection end can be close to or away from the clamping end;

[0008] A power measurement mechanism, the power measurement mechanism is electrically connected with the electrical connection piece, and the power measurement mechanism is used for detecting whether the electrical connection piece has current passing through; and

[0009] A wiring mechanism, the wiring mechanism is electrically connected with the electrical connection piece, and the wiring mechanism is used for being matched with a test wire.

[0010] In the aforementioned terminal block wiring test device, the tester first assembles the test lead with the wiring mechanism. The test lead is electrically connected to the connector through the wiring mechanism. Then, the connector at the connector end is wired to the terminal block. The tester controls the relative movement between the first and second gripping ends to bring the connector end closer to the clamping end, so that the clamping end abuts against the outer wall of the terminal block, preventing the connector from moving relative to the terminal block. At this time, when the measuring mechanism detects current flowing through the connector, it indicates that the connection between the connector and the terminal block is tight. When the measuring mechanism detects no current flowing through the connector, it indicates that the connection between the connector and the terminal block is not tight enough. The operator then adjusts the connector to ensure the tightness of the connection between the connector and the terminal block. Compared with traditional technology, the aforementioned terminal block wiring test device can ensure the tightness of the connection between the test lead and the terminal block through the abutment of the clamping end against the outer wall of the terminal block and the detection results of the measuring mechanism, thereby ensuring the accuracy of the test results.

The first conductive part is disposed in the first mounting cavity and is electrically connected to the wiring mechanism. The power receiving part is connected to the first conductive part and passes through the first opening. The power receiving part is used to assemble with the wiring terminal.

The terminal block wiring test device further includes a clamping member, which includes a second conductive part and a clamping part. The second conductive part is disposed in the second mounting cavity. The clamping part is connected to the second conductive part and passes through the second opening. The wiring mechanism is electrically connected to the second conductive part, and the second conductive part is electrically connected to the first conductive part.

[0017] In one embodiment, the terminal block wiring test device further includes a mounting shaft and a torsion spring.

Detailed Implementation

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] Please see Figures 1 to 3One embodiment of this application provides a terminal block wiring test device, including a first clamping mechanism 100, a second clamping mechanism 200, an electrical measuring mechanism 300, and a wiring mechanism 400. The first clamping mechanism 100 has a first gripping end 111 and a connecting end 112 disposed opposite to each other. The connecting end 112 is provided with a connecting element 500 for assembling with a terminal block. The first clamping mechanism 100 is provided with a first rotating part 113. The second clamping mechanism 200 has a first rotating part 113 disposed opposite to each other. The second gripping end 211 and clamping end 212 are provided. The second clamping mechanism 200 is provided with a second rotating part 213, which is rotatably connected to the first rotating part 113 so that the power receiving end 112 can approach or move away from the clamping end 212. The measuring mechanism 300 is electrically connected to the power receiving component 500 and is used to detect whether current flows through the power receiving component 500. The wiring mechanism 400 is electrically connected to the power receiving component 500 and is used to assemble with the test lead.

[0033] In the aforementioned terminal block wiring test device, the tester first assembles the test lead with the wiring mechanism 400. The test lead is electrically connected to the connector 500 through the wiring mechanism 400. Then, the connector 500 of the connector 112 is connected to the terminal block. The tester controls the relative movement between the first gripping end 111 and the second gripping end 211, so that the connector 112 approaches the clamping end 212, causing the clamping end 212 to abut against the outer wall of the terminal block, preventing the connector 500 from moving relative to the terminal block. At this time, when the current measuring mechanism 300 detects current flowing through the connector 500... If the current is not flowing through the connector 500, it indicates that the connection between the connector 500 and the terminal is tight. If the current measuring mechanism 300 detects no current flowing through the connector 500, it indicates that the connection between the connector 500 and the terminal is not tight enough. The operator then adjusts the connector 500 to ensure the tightness of the connection between the connector 500 and the terminal. Compared with traditional technology, the above-mentioned terminal block wiring test device can ensure the tightness of the connection between the test wire and the terminal by the contact of the clamping end 212 with the outer wall of the terminal and the detection result of the current measuring mechanism 300, thereby ensuring the accuracy of the test results.

[0034] As an explanation, the terminal block on the control cabinet includes multiple terminals arranged vertically (i.e., in the direction of gravity). During the wiring test of the terminal block, the tester needs to insert the plug of the test lead into different terminals. In this process, due to the large number and dense arrangement of the terminals, the long-term test will lead to an increase in the operator's error rate, which in turn will result in the test lead connector not being inserted to the trigger depth of the terminal, making the connection between the connector 500 and the terminal not tight enough, affecting the test results. In this application, the current measuring mechanism 300 is used to detect whether current flows through the connector 500 after the terminal is inserted, thereby ensuring the tightness of the connection between the connector 500 and the terminal and improving the accuracy of the test results.

[0035] Furthermore, to prevent the electrical connector 500 from being improperly connected to the terminal block wiring test device after the test personnel insert it into the terminal block, the operator can operate the first gripping end 111 and the second gripping end 211 to control the clamping end 212 to approach the electrical connector 112, so that the clamping end 212 can abut against the outer wall of the terminal block. At this time, the electrical connector 500 and the clamping end 212 can abut against the inside and outside of the terminal block respectively and generate friction, ensuring a stable connection between the terminal block wiring test device and the terminal block.

[0036] Optionally, the current measuring mechanism 300 can be a resistive current sensing element, a current transformer, a Hall element, etc., without specific limitations.

[0037] Furthermore, the wiring mechanism 400 is provided with wiring holes. When in use, the tester first inserts the plug of the test lead into the wiring hole to achieve electrical connection between the test lead and the electrical connector 500.

[0038] Optionally, in some embodiments, the first clamping mechanism 100 and the second clamping mechanism 200 can be cross-connected and rotatably connected (i.e., the first clamping mechanism 100 and the second clamping mechanism 200 cross to form an X-shape). When the tester controls the first gripping end 111 to move closer to the second gripping end 211, the power receiving end 112 can also move closer to the clamping end 212; when the tester controls the first gripping end 111 to move away from the second gripping end 211, the power receiving end 112 can also move away from the clamping end 212. In other embodiments, as shown in the accompanying drawings... Figures 1 to 2As shown, both the first clamping mechanism 100 and the second clamping mechanism 200 are bent (that is, both the first clamping mechanism 100 and the second clamping mechanism 200 are V-shaped). The first rotating part 113 is located at the bend of the first clamping mechanism 100, and the second rotating part 213 is located at the bend of the second clamping mechanism 200. The first rotating part 113 located at the bend of the first clamping mechanism 100 and the second rotating part 213 located at the bend of the second clamping mechanism 200 are rotatably connected. When the tester controls the first gripping end 111 to move closer to the second gripping end 211, the power-connecting end 112 moves away from the clamping end 212. When the tester controls the first gripping end 111 to move away from the second gripping end 211, the power-connecting end 112 moves closer to the clamping end 212.

[0039] Furthermore, the staff can control the electrical terminal 112 and the clamping terminal 212 to move closer or further apart by holding the first gripping end 111 and the second gripping end 211, which saves effort.

[0040] Please see Figures 1 to 3 In one embodiment, the first clamping mechanism 100 includes a first clamping member 110, which has a first gripping end 111 and a power receiving end 112 disposed opposite to each other. A first rotating part 113 is disposed in the first clamping member 110 and located between the first gripping end 111 and the power receiving end 112. The first clamping member 110 has a first mounting cavity and a first opening 114 that are connected to each other. The first opening 114 is opened at the power receiving end 112. The power receiving member 500 includes a first conductive part 510 and a power receiving part 520. The first conductive part 510 is disposed in the first mounting cavity and is electrically connected to the wiring mechanism 400. The power receiving part 520 is connected to the first conductive part 510 and passes through the first opening 114. The power receiving part 520 is used to assemble with a terminal block.

[0041] After the test lead is assembled with the wiring mechanism 400, the test lead can pass through the wiring mechanism 400, the first conductive part 510 and the connecting part 520 in sequence to achieve electrical connection with the terminal block. The first conductive part 510 is located in the first mounting cavity, which not only protects the first conductive part 510, but also prevents the operator from accidentally touching the first conductive part 510 and causing safety hazards. The connecting part 520 connected to the first conductive part 510 passes through the first opening 114 to achieve assembly with the terminal block, making the overall structure of the terminal block wiring test device compact.

[0042] In one embodiment, the first conductive part 510 includes a first conductive sheet whose shape matches the shape of the inside of the first mounting cavity, so as to fix the first conductive sheet in the first mounting cavity.

[0043] Furthermore, the first conductive sheet is fixed inside the first mounting cavity by a threaded component, which is low in implementation cost and has a reliable fixing effect.

[0044] In one embodiment, the contact part 520 includes a spring pin with a certain elasticity, which can better contact the terminal block.

[0045] Please see Figure 3 In one embodiment, the measuring mechanism 300 includes a resistive element 310, a neon tube 320, and a grounding element 330. The resistive element 310 is disposed in the first mounting cavity and electrically connected to the grounding part 520. The neon tube 320 is electrically connected to the resistive element 310. The first clamping member 110 also has a first contact window 115 communicating with the first mounting cavity. The grounding element 330 is electrically connected to the neon tube 320 and passes through the first contact window 115.

[0046] In use, when the tester touches the grounding element 330, and current flows through the energized part 520, the current will sequentially pass through the resistive element 310, the neon tube 320, the grounding element 330, and the tester, and finally flow to the ground to form a circuit. When there is current at the terminal, there is a certain potential difference between the terminal and the ground. At this time, the neon tube 320 will light up; otherwise, the neon tube 320 will not light up. The tester can confirm whether there is current flowing through the energized part 520 by observing the lighting of the neon tube 320, and thus confirm the tightness of the connection between the test lead and the terminal. The implementation process is convenient.

[0047] For explanation, the neon tube 320 contains neon gas. When the voltage of the neon tube 320 reaches a certain value, the neon gas ionizes and produces a glow effect, causing the neon tube 320 to emit light.

[0048] Furthermore, the detection range of the neon tube 320 is 50V-500V. For alternating current, the neon tube 320 emits light from both poles, while for direct current, the neon tube 320 emits light from only one pole.

[0049] In one embodiment, both the contact portion 520 and the contact element 300 are made of conductive metal.

[0050] Please see Figures 1 to 3 In one embodiment, the first clamping mechanism 100 further includes a first insulating sleeve 120, which is sleeved on the outside of the first clamping member 110 and has a second contact window 121, which is correspondingly provided with the first contact window 115.

[0051] The first insulating sleeve 120, which is fitted over the first clamp 110, can prevent workers from being electrocuted. The second contact window 121 is correspondingly provided with the first contact window 115. In this way, workers can touch the grounding element 330 through the second contact window 121 and the first contact window 115 in sequence, thereby improving the safety and convenience of using the terminal block wiring test device.

[0052] In one embodiment, the side wall of the first clamping member 110 is further provided with a first mounting port communicating with the first mounting cavity, so as to install the resistor element 310, the neon tube 320, the grounding element 330 and the power connector 500 into the first mounting cavity through the first mounting port.

[0053] Please see Figure 1 and Figure 3 In one embodiment, the first clamping member 110 is provided with at least two positioning portions 116, all of which are spaced apart circumferentially along the first contact window 115, and the positioning portions 116 abut against the inner wall of the second contact window 121.

[0054] This configuration ensures accurate alignment between the first contact window 115 and the second contact window 121, preventing test personnel from being unable to touch the grounding element 330 through the second contact window 121, and improving the reliability of the first insulating sleeve 120 and the first gripper.

[0055] Please see Figure 2 In one embodiment, the first insulating sleeve 120 is provided with an observation hole 122, which is correspondingly provided with the neon tube 320.

[0056] With this configuration, the light emitted by the neon tube 320 can pass through the observation hole 122, so that the test personnel can determine whether there is current flowing through the connector 500 after the terminal is inserted.

[0057] Furthermore, the neon tube 320 is provided with a light-emitting part, which passes through the observation hole 122 so that the test personnel can observe whether the light-emitting part emits light, and thus determine whether current flows through the electrical connector 500 after it is inserted into the terminal block.

[0058] Please see Figures 1 to 3 In one embodiment, the second clamping mechanism 200 includes a second clamping member 210, which has a second gripping end 211 and a clamping end 212 disposed opposite to each other. A second rotating part 213 is disposed in the second clamping member 210 and located between the second gripping end 211 and the clamping end 212. The second clamping member 210 has a second mounting cavity 214 and a second opening 215, which is located at the clamping end 212. The terminal block wiring test device also includes a clamping member 600, which includes a second conductive part 610 and a clamping part 620. The second conductive part 610 is disposed in the second mounting cavity 214. The clamping part 620 is connected to the second conductive part 610 and passes through the second opening 215. The wiring mechanism 400 is electrically connected to the second conductive part 610 and the second conductive part 610 is electrically connected to the first conductive part 510.

[0059] After the test lead is assembled with the wiring mechanism 400, the test lead can pass through the wiring mechanism 400, the second conductive part 610, the first conductive part 510 and the connecting part 520 in sequence to achieve electrical connection with the terminal block. The second conductive part 610 is located in the second mounting cavity 214, which not only protects the second conductive part 610, but also prevents personnel from accidentally touching the second conductive part 610 and causing safety hazards. The clamping part 620 passes through the second opening 215 and can abut against the outer wall of the terminal block. While ensuring a stable connection between the terminal block wiring test device and the terminal block, it also makes the overall structure of the terminal block wiring test device compact.

[0060] In one embodiment, the clamping part 620 is provided with a plurality of spaced friction protrusions to increase the friction between the clamping part 620 and the outer wall of the terminal block, thereby further ensuring a stable connection between the terminal block wiring test device and the terminal block.

[0061] Furthermore, the power connector 500 is also provided with a clamping engagement part, which is connected to the power connector 520. The clamping engagement part can cooperate with the clamping part 620 to abut against the inside and outside of the terminal block and generate friction force, thereby ensuring a stable connection between the terminal block wiring test device and the terminal block.

[0062] Furthermore, the clamping part 620 and the clamping mating part are a shark clip structure that meshes with each other.

[0063] Please see Figure 3 In one embodiment, the terminal block wiring test device further includes a mounting shaft 710 and a torsion spring 720. The first rotating part 113 is provided with a first mounting hole, and the second rotating part 213 is provided with a second mounting hole. The mounting shaft 710 passes through the first mounting hole and the second mounting hole. The torsion spring 720 is sleeved on the outer wall of the mounting shaft 710. One end of the torsion spring 720 abuts against the first conductive part 510 and is electrically connected to the first conductive part 510. The other end of the torsion spring 720 abuts against the second conductive part 610 and is electrically connected to the second conductive part 610.

[0064] The torsion spring 720 can abut against the first conductive part 510 and the second conductive part 610 through its own elasticity, so that the energized end 112 and the clamping end 212 tend to move closer to each other, ensuring a stable connection between the terminal block wiring test device and the terminal block. In addition, the torsion spring 720 can also conduct electricity. When the test wire is assembled with the wiring mechanism 400, the test wire can pass through the wiring mechanism 400, the second conductive part 610, the torsion spring 720, the first conductive part 510 and the energized part 520 in sequence to achieve electrical connection with the terminal block, and then the terminal block can be tested by the terminal block wiring test device.

[0065] Furthermore, since the internal installation space of the first clamping member 110 and the second clamping member 210 is limited, in order to ensure the compactness of the overall structure of the terminal block wiring test device, in this embodiment, the first conductive part 510 and the second conductive part 610 are respectively disposed in the first mounting cavity and the second mounting cavity 214, and the electrical connection between the first conductive part 510 and the second conductive part 610 is realized by the coil spring. In this way, while effectively utilizing the installation space, the first conductive part 510 and the second conductive part 610 can also be made conductive.

[0066] In one embodiment, two first rotating parts 113 are provided and are arranged parallel to each other and spaced apart, and two second rotating parts 213 are provided and are arranged parallel to each other and spaced apart. One first rotating part 113 is paired with one second rotating part 213, and the other first rotating part 113 is paired with the other second rotating part 213. The mounting shaft 710 passes through the first mounting holes of the two first rotating parts 113 and the second mounting holes of the two second rotating parts 213 to realize the rotatable connection between the first rotating parts 113 and the second rotating parts 213.

[0067] Furthermore, the mounting shaft 710 includes a pin and a screw. The pin passes through a first mounting hole of one of the first rotating parts 113 and a second mounting hole of one of the second rotating parts 213, and also passes through a first mounting hole of another first rotating part 113 and a second mounting hole of another second rotating part 213. It is then screwed to the screw. A coil spring is located between one of the first rotating parts 113 and the second rotating part 213 and the other first rotating part 113 and the second rotating part 213 to realize the assembly of the terminal block wiring test device.

[0068] Please see Figure 3 In one embodiment, the wiring mechanism 400 includes a terminal block disposed in the second mounting cavity 214. One end of the terminal block has a first wiring hole for the test wire to pass through, and the other end of the terminal block is electrically connected to the second conductive part 610.

[0069] The test lead is electrically connected to the terminal block through the first terminal hole. The end of the terminal block away from the first terminal hole is electrically connected to the second conductive part 610, thereby enabling the test lead to be electrically connected to the terminal block. This method is low in cost and has a reliable connection effect.

[0070] In one embodiment, the second conductive part 610 includes a second conductive sheet whose shape matches the shape inside the second mounting cavity 214, so as to fix the second conductive sheet inside the second mounting cavity 214.

[0071] Furthermore, the second conductive sheet is fixed inside the second mounting cavity 214 by a threaded component, which is low in implementation cost and has a reliable fixing effect.

[0072] In one embodiment, both the first conductive sheet and the second conductive sheet are copper conductive sheets.

[0073] Please see Figures 1 to 3 In one embodiment, the second clamping mechanism 200 further includes a second insulating sleeve 220, which is sleeved on the second clamping member 210 and has a second wiring hole 221, which is correspondingly provided with the first wiring hole.

[0074] The second insulating sleeve 220, which is fitted over the second clamp 210, can prevent workers from being electrocuted. The second wiring hole 221 is set in correspondence with the first wiring hole, so that workers can connect the test wire to the terminal block in sequence through the second wiring hole 221 and the first wiring hole, thereby improving the safety and convenience of using the terminal block wiring test device.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
