Description

Technical Field

[0001] This utility model relates to the field of locator signal debugging technology, specifically to a quick-release bracket for locator signal debugging. Background Technology

[0002] Straight-through terminal blocks are primarily used for wire connections in electrical connection processes and are the most commonly used electrical connection devices in industrial settings. In existing factory testing procedures, testers must follow a standard process: first, insert the test leads sequentially into the crimping holes of the corresponding straight-through terminals in the control cabinet under test; then, tighten the crimping screws using a tool. After testing, the crimping screws must be loosened before the test leads can be removed for the next test. This method is cumbersome and wastes a significant amount of time when dealing with a large number of positioners or when time is tight. Furthermore, it is easy to connect the test leads incorrectly, damaging the testing equipment and positioners. Summary of the Invention

[0003] To overcome the problem of cumbersome disassembly of test leads when testing multiple positioners, this utility model provides a quick-release bracket for positioner signal debugging.

[0004] To achieve the above objectives, this utility model provides a quick-release bracket for adjusting positioner signals, comprising: Fixture; The test lead terminal block includes a PCB board and multiple spring pins. The PCB board is mounted on the mounting bracket, and the multiple spring pins are mounted on the PCB board. The spring pins are used to insert into the sockets of the general-purpose terminals and abut against the wire clamping screws inside the sockets. The wire clamping screws are connected to the test lead of the positioner. A test lead inlet terminal is provided for connecting the test leads of the testing equipment. The test lead inlet terminal is inserted into the mounting bracket, allowing the test leads of the testing equipment to connect to the spring pin. Two clamping brackets are connected to both sides of the fixing bracket by compression springs. The inner side of the clamping bracket is provided with a slot for engaging with the protrusion on the outer side of the universal terminal. The clamping bracket is made of plastic.

[0005] Optionally, the quick-release bracket for locator signal debugging further includes a fixing screw, one end of which is screwed to a thermoplastic nut, the thermoplastic nut being connected to the fixing frame, a compression spring being sleeved on the outer periphery of the fixing screw, the clamping frame having a sliding cavity, the compression spring being disposed in the sliding cavity, and both ends being connected to the cavity wall of the sliding cavity and the fixing screw, respectively.

[0006] Optionally, multiple sets of the fixing screws, the thermosetting nuts, and the compression springs are provided and symmetrically arranged on both sides of the fixing frame.

[0007] Optionally, the clamping frame is equipped with a handle.

[0008] Optionally, the fixing bracket is provided with a plug hole, and the two opposite holes of the plug hole in the height direction form a first large step and a first small step. The end of the test lead terminal near the plug hole forms a second large step and a second small step, and the first large step and the first small step abut against the second large step and the second small step, respectively.

[0009] Optionally, the universal terminal is provided with multiple sockets.

[0010] Optionally, the PCB board is provided with multiple mounting holes, multiple bolts pass through a portion of the multiple mounting holes to mount the PCB board to the mounting bracket, and multiple spring pins are soldered to the PCB board through another portion of the multiple mounting holes. The technical solutions provided by the embodiments of this utility model may include the following beneficial effects: The positioner's multiple test leads are connected to universal terminals, which are installed inside the control cabinet under test. When testing a positioner, press the two clamping brackets towards the universal terminals, causing the protrusions on the outside of the universal terminals to engage with the slots of the clamping brackets. This allows multiple spring pins on the PCB board to insert into the multiple sockets of the universal terminals. At this time, the spring pins are connected to the positioner's test leads via the wire clamping screws, and the compression springs are in a compressed state, pulling the two clamping brackets inward to ensure a stable connection between the positioner signal debugging quick-release bracket and the universal terminals. Connect the test lead terminals to the multiple test leads of the testing equipment, and then insert the test lead terminals into the base body. This allows the testing equipment's test leads to connect to the spring pins through the PCB board. In other words, the testing equipment's test leads are connected to the positioner's test leads after passing through the PCB board, spring pins, and wire clamping screws, enabling the testing equipment to test the positioner as scheduled. When testing the next positioner, simultaneously pull both clamps outwards to separate the clamp slots from the protrusions on the outside of the universal terminal. Move the clamps away from the universal terminal so that they can move the fixing bracket away from the universal terminal, thus removing the spring pin from contact with the universal terminal's wire screw. Then, snap the positioner signal debugging quick-release bracket onto the universal terminal corresponding to the next positioner for quick and convenient positioner testing. This eliminates the need to connect multiple test leads of the testing equipment to the universal terminal of the positioner under test each time, improving testing efficiency and preventing incorrect wiring sequence of multiple test leads during multiple tests, ensuring the integrity of the testing equipment and the positioner.

[0018] Understandably, the multiple test leads of the positioner are connected to the universal terminal 0, which is installed inside the control cabinet under test. When a positioner needs to be tested, press the two clamping brackets 40 towards the universal terminal 0, causing the protrusion 02 on the outside of the universal terminal 0 to engage with the slot 41 of the clamping bracket 40. This allows the multiple spring pins 22 on the PCB board 21 to be inserted into the multiple sockets 01 of the universal terminal 0.

When testing the next positioner, simultaneously pull both clamping brackets 40 outwards, causing the slots 41 of the clamping brackets 40 to separate from the protrusions 02 on the outside of the universal terminal 0. Move the clamping brackets 40 away from the universal terminal 0, allowing them to move the fixing bracket 10 away from the universal terminal 0, thus preventing the spring pin 22 from contacting the wire screw of the universal terminal 0. Then, snap the positioner signal debugging quick-release bracket onto the universal terminal 0 corresponding to the next positioner for quick and convenient positioner testing. This eliminates the need to connect multiple test leads of the testing equipment to the universal terminal 0 of the positioner under test each time, improving testing efficiency and preventing incorrect wiring sequence of multiple test leads during multiple tests, ensuring the integrity of the testing equipment and the positioner.
