Description

Technical Field

[0001] This utility model relates to the field of electrical component testing technology, specifically to an electrical component testing wiring device. Background Technology

[0002] In the production and testing of electrical components, it is often necessary to test their electrical performance, which requires reliable connection between the component's wires and the testing instruments. Traditional wiring methods often use screw fastening or plug-in connectors, which are cumbersome to operate. Especially during batch testing, frequent wiring operations can significantly reduce work efficiency.

[0003] For example, the national authorized patent announcement number CN113092830B discloses an electrical component testing rack and its operating process, belonging to the technical field of electrical testing. It includes a test base, two support plates fixedly connected to the test base, a test base plate rotatably mounted between the two support plates, a test disc mounted on the upper side of the test base plate, and a test box mounted on the test base between the two support plates. Rotating rollers are fixedly connected to the side walls of the test base plate near the two support plates, and these rotating rollers pass through adjacent support plates and are rotatably connected to them. A drive motor fixedly connected to the rotating rollers is fixedly connected to one of the support plates; a transmission mechanism connected to the rotating rollers and driving the test box to slide along the upper surface of the test base is mounted on the other support plate. This application has the effect of reducing the possibility that electrical components, after being thrown out, may not accurately land in the test box.

[0004] However, although the aforementioned electrical component test rack and its operating process have solved the positioning and connection problems during electrical component testing, they have not broken through the limitations of traditional methods in the core wire connection process. When connecting the electrical component wires to the test box, the test rack still relies on conventional screw fastening or plug-in connector structures. Not only are the operation steps cumbersome, but in batch testing scenarios, staff need to repeatedly tighten screws and plug and unplug connectors, resulting in low efficiency of the overall testing process. Utility Model Content

[0005] The purpose of this utility model is to provide a wiring device for testing electrical components, so as to solve the problems mentioned in the background art, such as cumbersome operation, low efficiency of batch testing, inaccurate test data due to poor contact between the wire and the test component, poor adaptability to different specifications of wires, and the need to frequently replace connectors or adjust components.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electrical component testing wiring device includes: a tester, one end of which has a corresponding mounting port, a U-shaped frame fixedly installed in the mounting port, a conical cover fixedly installed in the U-shaped frame, a copper pressure plate fixedly installed at one end of the conical cover, and a locking mechanism rotatably installed in the conical cover. When a wire of an electrical component is inserted into the U-shaped frame, the locking mechanism pulls down and drives the copper pressure plate to press the wire into place, thus achieving conductivity.

[0008] Preferably, a contact plate is embedded and fixedly installed at one end of the mounting port. The contact plate is electrically connected to the tester and slides in contact with the copper pressure plate, so that the copper pressure plate can be detected by the tester after it is connected to the wire.

[0009] Preferably, the lower surface of the copper pressure plate is fixedly equipped with anti-detachment teeth.

[0010] Preferably, the locking mechanism includes an insulating rod, which is rotatably mounted on the cone cover and slides out from the lower end of the U-shaped frame and the tester, so that the insulating rod can be pulled down to drive the copper pressure plate to press against the outer surface of the wire inserted into the U-shaped frame.

[0011] Preferably, the upper surface of the insulating rod is fixedly connected to the center of the mainspring, while the outer surface of the mainspring is fixedly connected to the inner ring wall of the cone cap.

[0012] Preferably, one end of the outer surface of the insulating rod is provided with multiple sets of right-angled locking grooves, the locking grooves can be inserted into the locking blocks, the locking blocks are slidably installed in the connecting cylinder, the connecting cylinder is fixedly installed in one end of the U-shaped frame, a rectangular spring is fixedly connected to one end of the connecting cylinder, and the other end of the rectangular spring is fixedly connected to one end of the locking block.

[0013] Preferably, when the insulating rod is pulled down, the inclined sliding surface of the locking groove can generate a top pressure on the locking block, causing the locking block to retract into the interior of the connecting cylinder; after the locking block passes the corresponding mating area of ​​the locking groove at the current position, the rectangular spring can release elastic potential energy to drive the locking block to reset and pop out, thereby making the locking block and the locking groove at the current position form a snap-fit ​​positioning engagement;

[0014] When it is necessary to release the locking block from the locking groove, a rotational force is applied to the insulating rod, which can disengage the locking groove from the outer surface of the locking block. After the locking groove is completely disengaged from the locking block, the spring can release its stored energy to drive the insulating rod to return to its initial assembly position.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Through the linkage design of the insulating rod, cone cap, and copper pressure plate, combined with the progressive locking structure of the locking groove, locking block, and rectangular spring, the operator only needs to insert the wire and pull down the insulating rod to quickly complete the wire clamping without complicated operations. At the same time, the high conductivity of the copper pressure plate and the sliding contact design of the contact plate can form a stable conductive circuit, ensuring accurate test data. After the test, twisting the insulating rod can release the lock, and the spring can drive the insulating rod to automatically reset and re-lock, making it easy to pull out the wire and quickly return the device to the standby state. This not only greatly simplifies the operation process and improves the testing efficiency, but also adapts to different specifications of wires, reduces equipment adjustment and maintenance costs, and balances practicality and economy.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3As shown, this embodiment provides a wiring device for testing electrical components, including: a tester 1, with a corresponding mounting port 101 at one end of the tester 1. A U-shaped frame 102 is fixedly installed inside the mounting port 101, and a conical cover 105 is fixedly installed inside the U-shaped frame 102. A copper pressure plate 103 is fixedly installed at one end of the conical cover 105, and a locking mechanism 2 is rotatably installed inside the conical cover 105. This allows the wire of the electrical component to be inserted into the U-shaped frame 102, and the locking mechanism 2 pulls down, causing the copper pressure plate 103 to press the wire into place, thus achieving conductivity. A contact plate 104 is embedded and fixedly installed at one end of the mounting port 101. The contact plate 104 is electrically connected to the tester 1, and the contact plate 104 slides in contact with the copper pressure plate 103, so that the copper pressure plate 103 can be detected by the tester 1 after it has made contact with the wire. Anti-dislodgement teeth are fixedly installed on the lower surface of the copper pressure plate 103.

[0024] Through the design of the tester 1, U-shaped frame 102, copper pressure plate 103, contact plate 104, conical cover 105, and locking mechanism 2, during use, the operator only needs to align the end of the wire of the electrical component to be tested with the opening end of the U-shaped frame 102 and insert it. The operator can then pull down the locking mechanism 2 to move the copper pressure plate 103 downwards synchronously until the lower surface of the copper pressure plate 103 is tightly attached to the metal conductor of the wire. At this time, the anti-dislodgement teeth on the lower surface of the copper pressure plate 103 will embed into the surface of the wire, increasing the friction and preventing the wire from vibrating during the test. If the wire shifts or falls off due to pulling, the locking component of the locking mechanism 2 will automatically engage, fixing the copper pressure plate 103 in the current pressing position. This eliminates the need for continuous force application by the operator, achieving rapid and stable fixing of the wire. After the wire is pressed by the copper pressure plate 103, because the copper pressure plate 103 is made of highly conductive material, it will form a reliable electrical connection with the metal conductor of the wire. Furthermore, since the copper pressure plate 103 maintains sliding contact with the contact plate 104, and the contact plate 104 is electrically connected to the tester 1, the electrical component to be tested, the wire, the copper pressure plate 103, and the contact plate 104 are all in a secure connection. A complete conductive circuit is formed between the plate 104 and the tester 1. After the operator starts the tester 1, the tester 1 can output test signals to the electrical components through this circuit, and at the same time collect feedback data from the electrical components. The test results are then output through the display panel or data interface of the tester 1, enabling accurate detection of the electrical performance of the electrical components. During this process, the sliding contact design between the copper pressure plate 103 and the contact plate 104 ensures that even if the copper pressure plate 103 undergoes slight positional changes due to different wire specifications, it can still maintain a stable conductive connection, avoiding test data deviations due to poor contact. After a single test is completed, the operator can release the locking component by rotating the locking mechanism 2 and push it back to its original position, releasing the pressure on the wires. The operator can then pull the wires out of the U-shaped frame 102, completing the test process for a single electrical component. The device then automatically returns to the initial standby state, allowing direct testing of the next electrical component. The process does not require additional disassembly or adjustment steps, making it particularly suitable for batch testing scenarios, significantly shortening the test interval time and improving overall work efficiency.

[0025] like Figure 4As shown, the locking mechanism 2 includes an insulating rod 201, which is rotatably mounted on the conical cover 105 and slides through the lower end of the U-shaped frame 102 and the tester 1. This allows the insulating rod 201 to be pulled down to press the copper pressure plate 103 against the outer surface of the wire inserted into the U-shaped frame 102. The upper surface of the insulating rod 201 is fixedly connected to the center of the spring 202, while the outer surface of the spring 202 is fixedly connected to the inner ring wall of the conical cover 105. One end of the outer surface of the insulating rod 201 has multiple sets of right-angled locking grooves 203. Locking blocks 206 can be inserted into the locking grooves 203. The locking blocks 206 are slidably mounted in the connecting cylinder 204. The connecting cylinder 204 is fixedly mounted in one end of the U-shaped frame 102. A rectangular spring 205 is fixedly connected to one end of the connecting cylinder 204, and the other end of the rectangular spring 205 is fixedly connected to one end of the locking block 206.

[0026] When the insulating rod 201 is pulled down, the inclined sliding surface of the locking groove 203 can generate a top pressure on the locking block 206, causing the locking block 206 to retract into the connecting cylinder 204; after the locking block 206 passes the corresponding mating area of ​​the locking groove 203 at the current position, the rectangular spring 205 can release elastic potential energy to drive the locking block 206 to reset and pop out, thereby making the locking block 206 and the locking groove 203 at the current position form a snap-fit ​​positioning engagement;

[0027] When it is necessary to release the locking block 206 from the locking groove 203, a rotational force is applied to the insulating rod 201, which can disengage the locking groove 203 from the outer surface of the locking block 206. After the locking groove 203 and the locking block 206 are completely disengaged, the spring 202 can release its stored energy to drive the insulating rod 201 to reset to the initial assembly position.

[0028] Through the design of the insulating rod 201, the spring 202, the locking groove 203, the connecting cylinder 204, the rectangular spring 205, and the locking block 206, after the operator inserts the wire end of the electrical component to be tested into the open end of the U-shaped frame 102, the operator can pull down the insulating rod 201. Since the insulating rod 201 is rotatably mounted on the cone cover 105, and the cone cover 105 is fixedly connected to the copper pressure plate 103, the pulling action directly drives the copper pressure plate 103 to move down synchronously. As the insulating rod 201 moves down, the multiple sets of right-angled locking grooves 203 on its outer surface move synchronously. When the locking groove 203 moves to the position corresponding to the locking block 206 in the connecting cylinder 204, the inclined sliding surface of the locking groove 203 will press against the locking block 206, causing the locking block 206 to lock down. Overcoming the elastic force of the rectangular spring 205 inside the connecting cylinder 204, the insulating rod 201 slides and retracts into the connecting cylinder 204, and is re-engaged with the arrival of the next set of locking grooves 203, and is then pushed in again. This process is repeated until the insulating rod 201 is pulled down to the lower surface of the copper pressure plate 103 and is tightly attached to the metal conductor of the wire, so that the locking groove 203 at the current position can be locked by the locking block 206, thereby achieving the locking and fixing of the insulating rod 201. At this time, the copper pressure plate 103 is stably limited in the pressed position. After the wire is pressed by the copper pressure plate 103, since the copper pressure plate 103 is a highly conductive material, it forms a reliable electrical connection with the metal conductor of the wire. Also, because the copper pressure plate 103 maintains sliding contact with the contact plate 104, and the contact plate 104 is electrically connected to the tester 1, the electrical component and wire to be tested... A complete conductive circuit is formed between the copper pressure plate 103, the contact plate 104, and the tester 1. After the operator starts the tester 1, the tester 1 outputs a test signal to the electrical component through this circuit, simultaneously collects feedback data from the electrical component, and outputs the test results through the display panel or data interface, achieving accurate detection of the electrical performance of the electrical component. After a single test, the operator can twist the insulating rod 201 to shift the relative position of the locking groove 203 on the insulating rod 201 and the locking block 206, allowing the locking groove 203 to disengage from the outer surface of the locking block 206, thus releasing the locking state. During this process, the insulating rod 201 will also drive the spring 202 to be twisted, and then the insulating rod 201 can be used to drive the copper pressure plate 103 to be twisted. After being pushed back to its higher position, the insulating rod 201 can be released. The torsional force released by the spring 202 causes the insulating rod 201 to rotate back and re-engage with the locking slot 203, re-engaging with the locking block 206. The operator can then pull the wire out of the U-shaped frame 102, and the device returns to its initial standby state. The device, through its progressive adjustment design with multiple sets of locking slots 203, can accommodate wires of different diameters. When the insulating rod 201 is pulled down, the reciprocating engagement of the locking slot 203 and the locking block 206 automatically adjusts the pressing depth of the copper pressure plate 103 according to the wire thickness, eliminating the need to replace pressure plates or connectors of the corresponding specifications. Furthermore, the force with which the copper pressure plate 103 presses the wire is stably maintained by the locking structure, eliminating the need for operators to adjust the tightening force according to the wire specifications.To prevent loosening of the wires due to insufficient force or damage due to excessive force, this strong adaptability allows the device to be compatible with various specifications of electrical component wires. This eliminates the need to purchase additional special connectors or accessories for different testing needs, reducing equipment procurement and maintenance costs, and also simplifying the learning curve for staff operating different wire specifications.

[0029] Based on the above technical solution, the working steps of this solution are summarized as follows: During use, the operator only needs to align the end of the wire of the electrical component to be tested with the opening end of the U-shaped frame 102 and insert it. Then, the operator can pull down the insulating rod 201. Since the insulating rod 201 is rotatably mounted on the cone cover 105, and the cone cover 105 is fixedly connected to the copper pressure plate 103, the pulling action directly drives the copper pressure plate 103 to move downwards synchronously. As the insulating rod 201 moves downwards, the multiple sets of right-angled locking grooves 203 on its outer surface move synchronously. When the locking groove 203 moves to the position corresponding to the locking block 206 inside the connecting cylinder 204, locking occurs. The inclined sliding surface of slot 203 presses against locking block 206, causing locking block 206 to overcome the elastic force of rectangular spring 205 inside connecting cylinder 204 and slide and retract into connecting cylinder 204. As the next set of locking slots 203 arrives, it re-engages and is pressed in again, repeating this process until the insulating rod 201 is pulled down to the lower surface of copper pressure plate 103 and tightly adheres to the metal conductor of the wire. This allows the locking slot 203 at the current position to be locked by locking block 206, thus locking and fixing the insulating rod 201. At this point, copper pressure plate 103 is stably limited to the pressed position. After the wire is pressed by copper pressure plate 103, because copper pressure plate 103 is a highly conductive material, its... A reliable electrical connection is formed between the copper pressure plate 103 and the contact plate 104, and the contact plate 104 is electrically connected to the tester 1. A complete conductive circuit is formed between the electrical component to be tested, the wire, the copper pressure plate 103, the contact plate 104, and the tester 1. After the operator starts the tester 1, the tester 1 outputs a test signal to the electrical component through this circuit, simultaneously collects feedback data from the electrical component, and outputs the test results through the display panel or data interface, achieving accurate detection of the electrical performance of the electrical component. After a single test, the operator can twist the insulating rod 201 to adjust the insulation... The relative positions of the locking groove 203 on the rod 201 and the locking block 206 shift, allowing the locking groove 203 to disengage from the outer surface of the locking block 206, thus releasing the locking state. During this process, the insulating rod 201 will also cause the spring 202 to be twisted. After the insulating rod 201 and the copper pressure plate 103 are pushed back to a higher position, the insulating rod 201 can be released, allowing the insulating rod 201 to rotate back to the locking groove 203 and re-engage with the locking block 206 through the torsional force released by the spring 202. Then, the operator can pull the wire out of the U-shaped frame 102, and the device returns to its initial standby state.

[0030] In summary, staff only need to follow five steps to complete the test of a single electrical component: "insert wire - pull down insulating rod 201 - start test - twist to reset - pull out wire". The entire process does not require screw tightening, connector replacement or complex parameter adjustment. In batch testing scenarios, the device does not need to be stopped frequently for adjustment, and staff can continuously complete multiple sets of tests, greatly reducing operation intervals and significantly improving overall testing efficiency.

[0031] Taking the HH52P relay as the test element and the TH2512 low resistance tester as an example, the following test principle and method are provided:

[0032] I. Testing Principles

[0033] 1. Adaptation logic between the device, the test object, and the test instrument

[0034] The HH52P relay is a small electromagnetic relay. Its core testing requirements are coil continuity verification (determining if the coil is open-circuited) and contact resistance measurement (determining if the contacts are oxidized or have poor connections). Its coil rated resistance is approximately 95-105Ω (12V specification), and the contact resistance requirement is ≤50mΩ. The TH2512 low resistance tester uses a four-terminal measurement method (current terminal + voltage terminal separated), which can eliminate lead resistance interference. The test range is 0.1μΩ-20kΩ, with an accuracy of ±0.05%, and is suitable for the low resistance testing requirements of the HH52P relay.

[0035] This device achieves a reliable connection between the relay and the tester through a dual function of "mechanical fixation + electrical conduction":

[0036] Mechanical fixing layer: The lead wires of the HH52P relay (coil pins 13 / 14 or contact pins 1 / 2) are positioned by the U-shaped frame (102). The insulating rod (201) is pulled down to drive the copper pressure plate (103) (which needs to be corrected to "slide along the built-in groove of the cone cover (105)") to press the wires. The anti-loosening teeth are embedded in the outer surface of the wire insulation layer to avoid the contact resistance fluctuation caused by the displacement of the wire during the test.

[0037] Electrical conduction layer: The copper pressure plate (103) is made of T2 copper (conductivity ≥98%). After pressing the wire, it forms a surface contact with the metal core of the wire. At the same time, the copper pressure plate (103) and the contact plate (104) (tin-plated to prevent oxidation) embedded in the mounting port (101) maintain sliding contact. The contact plate (104) is connected to the “current output terminal (I+, I-)” and “voltage measurement terminal (V+, V-)” of the TH2512 tester through the wire, forming a closed test circuit of “TH2512→contact plate (104)→copper pressure plate (103)→HH52P relay→copper pressure plate (103)→contact plate (104)→TH2512”.

[0038] 2. Key Test Feature Adaptation Principles

[0039] Coil continuity test: The HH52P relay coil resistance is approximately 100Ω, which is in the low to medium resistance range. The TH2512 is set with a constant test current of 1A (to avoid measurement errors caused by too low a current and burnout of the coil by too high a current). The current flows through the coil in the device circuit. The tester collects the voltage across the coil through the voltage terminal and calculates the coil resistance according to Ohm's law (R=U / I). If the resistance is within the range of 95-105Ω, the coil is considered to be conducting normally.

[0040] Contact resistance test: The HH52P relay contacts are made of silver alloy. The normal contact resistance is ≤50mΩ. Switch the TH2512 to "low resistance range (0-200mΩ)" and set a test current of 10A (which meets the test current requirements for contact resistance of IEC60947 standard). When the current flows through the contact, the tester accurately collects the micro voltage (mV level) across the contact and calculates the contact resistance. If it is ≤50mΩ, the contact is considered to be in good contact.

[0041] II. Test Methods (for batch testing of HH52P relays)

[0042] 1. Preparation before testing (1 step, adapter device in "standby state")

[0043] Equipment pretreatment:

[0044] Turn on the TH2512 low resistance tester and preheat for 30 minutes (to ensure the internal reference power supply is stable). Press the "calibration button" and perform two-point calibration using standard resistors (100Ω, 50mΩ). After calibration, connect the tester's "current terminal (I+, I-)" and "voltage terminal (V+, V-)" to the two sets of contact plates (104) of the device through shielded wires (one set corresponds to the relay coil, and the other set corresponds to the contact point. The device needs to be equipped with two sets of independent U-shaped brackets (102) to achieve simultaneous testing).

[0045] Check the status of HH52P relay pins: Confirm that coil pins 13 / 14 and normally open contact pins 1 / 2 are free from oxidation (if oxidation is present, lightly polish with 1000-grit sandpaper), and remove the insulation layer at the pin ends (exposing 5mm of metal core, suitable for the crimping length of the copper pressure plate (103)).

[0046] 2. Testing Operation (5 steps, matching device "five-step operation" design)

[0047] Step 1: Insert the wire (positioning relay)

[0048] Insert the two sets of test leads of the HH52P relay into the corresponding brackets (102) of the device:

[0049] Coil circuit: Insert the lead wire of pin 13 into the "coil test group" frame (102), and insert the lead wire of pin 14 into another frame (102) in the same group;

[0050] Contact circuit: Insert the lead wire of pin 1 into the "contact test group" frame (102), and insert the lead wire of pin 2 into another frame (102) in the same group;

[0051] Wire insertion depth control: The wire metal core is fully inserted directly below the copper pressure plate (103) (the device can be equipped with a "limiting boss" to indicate the insertion depth).

[0052] Step 2: Pull down the insulating rod (mechanical fixation + electrical contact)

[0053] Pull down the insulating rods (201) of the two locking mechanisms (2) simultaneously with both hands:

[0054] Pull-down force: The standard is to feel the "stepped engagement" between the locking block (206) and the locking groove (203) (the engagement is triggered once every 5mm pull down, which is suitable for different wire diameters), until the copper pressure plate (103) completely covers the metal core of the wire (the engagement status can be confirmed through the "observation window" on the side of the device).

[0055] Locking confirmation: After pulling down, gently pull the wire. If the wire does not move, it means that the anti-disengagement tooth has been effectively embedded. The locking block (206) and the current locking groove (203) form a stable engagement. The copper pressure plate (103) forms a reliable electrical contact with the wire and the contact plate (104).

[0056] Step 3: Start the test (data acquisition)

[0057] Set the test parameters on the TH2512 tester:

[0058] Coil test channel: Test mode "Constant Current 1A", range "0-200Ω", sampling time "100ms" (fast batch test);

[0059] Contact test channel: Test mode "Constant Current 10A", range "0-200mΩ", sampling time "200ms" (micro resistance measurement requires a longer stabilization time);

[0060] Press the "Continuous Test" button on the tester, and the instrument will simultaneously collect data on coil resistance and contact resistance, and display them on the screen in real time (the "Pass / Fail" audible and visual alarm can be turned on, and the pass range for coil resistance is set to 95-105Ω, and the pass range for contact resistance is ≤50mΩ).

[0061] Step 4: Twist and reset (unlock)

[0062] After the test is completed (test time for a single relay ≤ 1s), rotate the insulating rod (201) clockwise by 30° simultaneously with both hands (the rotation angle must be clearly marked on the device):

[0063] During rotation, the inclined sliding surface of the locking groove (203) disengages from the locking block (206) and the locking block (206) retracts into the connecting cylinder (204) under the action of the rectangular spring (205), thus releasing the locking state;

[0064] Release the insulating rod (201), and the spring (202) (which needs to be corrected to "only bear circumferential torque"; if a turntable is provided at the upper end of the insulating rod, the center of the spring is fixed to the turntable) releases its stored energy, causing the insulating rod (201) to rotate counterclockwise to reset, and simultaneously pulling the copper pressure plate (103) to move upward along the slide groove and detach from the conductor.

[0065] Step 5: Remove the wire (to replace the relay)

[0066] Directly disconnect the two sets of wires of the HH52P relay. If it is a qualified product, put it in the "qualified area". Mark the fault type of the unqualified product (such as "coil open circuit" or "contact resistance too high"). Then repeat steps 1-5 to test the next HH52P relay (when testing in batches, ≥300 units can be tested per hour, which is much higher than ≤50 units / hour of the traditional screw fastening method).

[0067] 3. Post-test maintenance (1 step, to ensure device stability)

[0068] After the test, turn off the TH2512 tester, wipe the surface of the copper pressure plate (103) and contact plate (104) with anhydrous ethanol (to remove residual oxide debris from the wires), check whether the locking block (206) is stuck (if stuck, drip 1 drop of sewing machine oil for lubrication), and ensure the reliability of the device when used next time.

[0069] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.

A copper pressure plate (103) is fixedly installed at one end of the cone cover (105). A locking mechanism (2) is rotatably installed in the cone cover (105). When the wire of the power supply component is inserted into the U-shaped frame (102), the wire can be pressed into the copper pressure plate (103) by the downward pull of the locking mechanism (2) to achieve conductivity.

2. The electrical component testing wiring device according to claim 1, characterized in that: A contact plate (104) is embedded in one end of the mounting port (101). The contact plate (104) is electrically connected to the tester (1). The contact plate (104) slides in contact with the copper pressure plate (103), so that the copper pressure plate (103) can be detected by the tester (1) after it is connected to the wire.

3. The electrical component testing wiring device according to claim 2, characterized in that: The lower surface of the copper pressure plate (103) is fixedly equipped with anti-detachment teeth.

4. The electrical component testing wiring device according to claim 2, characterized in that: The locking mechanism (2) includes an insulating rod (201) which is rotatably mounted on the cone cover (105) and slides out from the lower end of the U-shaped frame (102) and the tester (1), so that the insulating rod (201) can be pulled down to drive the copper pressure plate (103) to press against the outer surface of the wire inserted into the U-shaped frame (102).

5. The electrical component testing wiring device according to claim 4, characterized in that: The upper surface of the insulating rod (201) is fixedly connected to the center of the spring (202), while the outer surface of the spring (202) is fixedly connected to the inner ring wall of the cone cap (105).

6. The electrical component testing wiring device according to claim 5, characterized in that: The outer surface of the insulating rod (201) has multiple sets of right-angled locking grooves (203) at one end. The locking grooves (203) can be inserted into the locking blocks (206). The locking blocks (206) are slidably installed in the connecting tube (204). The connecting tube (204) is fixedly installed in one end of the U-shaped frame (102). A rectangular spring (205) is fixedly connected to one end of the connecting tube (204). The other end of the rectangular spring (205) is fixedly connected to one end of the locking block (206).

7. The electrical component testing wiring device according to claim 6, characterized in that: When the insulating rod (201) is pulled down, the inclined sliding surface of the locking groove (203) can generate a top pressure on the locking block (206), causing the locking block (206) to retract into the interior of the connecting cylinder (204); after the locking block (206) passes the corresponding mating area of ​​the locking groove (203) at the current position, the rectangular spring (205) can release elastic potential energy to drive the locking block (206) to reset and pop out, thereby making the locking block (206) and the locking groove (203) at the current position form a snap-fit ​​positioning engagement; When it is necessary to release the locking block (206) from the locking groove (203), a rotational force is applied to the insulating rod (201), which can cause the locking groove (203) to disengage from the outer surface of the locking block (206); after the locking groove (203) and the locking block (206) are completely disengaged, the spring (202) can release its stored energy to drive the insulating rod (201) to reset to the initial assembly position.
