Description

Technical Field

[0001] This utility model relates to the technical field of PCB module current testing equipment, and in particular to a high-current output clamp that can be quickly clamped. Background Technology

[0002] Currently, when performing high-current output tests on PCB modules, it is necessary to stably connect the testing device to the output terminals of the PCB module.

[0003] In existing technologies, OT6-4 terminals are typically cold-pressed onto cables and directly connected to the output terminals of the PCB module. Installation requires the use of an electric screwdriver to remove and install the screws. This method is cumbersome and time-consuming, which seriously affects the production efficiency of PCB module debugging. Moreover, repeated use of a screwdriver to tighten the screws can easily damage the threads on the output terminals, leading to terminal failure and increasing testing costs. This method cannot meet the requirements for efficient and reliable testing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-current output clamp that can be quickly clamped.

[0005] This utility model is achieved using the following technical solution: a high-current output fixture capable of rapid clamping, comprising a PCB module, a test component capable of rapidly testing the current of the output terminals of the PCB module on one side, a reset component capable of automatically resetting the test component when current testing is not required on one side, the test component comprising a pressing block disposed on one side of the top of the PCB module terminals, the pressing block being hollow and convex, a plurality of output heads disposed on the bottom side of the pressing block, a metal rod fixedly mounted on the top of each output head, the top of each metal rod extending upwards into the interior of the pressing block and fixedly mounted with a metal sheet, and an electrical wire connected to one side of each metal sheet.

[0006] Through the above technical solution, the hollow convex pressure block can stably support components such as output heads and metal rods. Multiple output heads can be precisely connected to multiple sets of output terminals of the PCB module to meet the requirements of high current testing. The metal rod and metal sheet form a conductive path, which, together with the wire, realizes current transmission and ensures stable current output during the test.

[0007] As a further improvement to the above solution, each of the metal rods is fitted with a spring, and the two ends of each spring are fixedly installed with the adjacent output head and the lower pressure block, respectively.

[0008] Through the above technical solution, the spring has an elastic buffering effect. When the output head contacts the output terminal of the PCB module, the spring can compensate for the contact gap through compression, so that the output head and the terminal fit tightly and improve the conductivity stability. At the same time, the spring's rebound force can prevent the output head from rigidly squeezing the terminal and protect the terminal from damage.

[0009] As a further improvement to the above solution, the PCB module is covered with a protective shell, and a quick clamp is fixedly installed on the top side of the protective shell, with a pressure head fixedly installed on the pushing end of the quick clamp.

[0010] Through the above technical solutions, the protective shell can protect the PCB module and internal test components, preventing external dust and impurities from affecting the test accuracy; the quick clamp, as the core operating component, can move the pressure head up and down by manual drive, without the need for power tools, realizing the quick clamping and disassembly of the PCB module, and greatly shortening the test preparation time.

[0011] As a further improvement to the above solution, the reset assembly includes a general assembly bracket fixedly installed inside the protective shell. The general assembly bracket is concave in shape. A linear guide rail is fixedly installed inside the general assembly bracket. An output module bracket is fixedly installed on the slide of the linear guide rail. A top plate is hinged to one side of the top of the output module bracket. The top plate is concave in shape. The top of the lower pressure block is located inside the top plate and is fixedly installed with the top plate.

[0012] Through the above technical solution, the concave assembly bracket provides a stable mounting foundation for the linear guide rail and the output module bracket; the linear guide rail limits the movement direction of the output module bracket, ensuring that it moves only in the vertical direction, avoiding misalignment caused by test component displacement; the concave top plate is fixedly connected to the lower pressure block, which can drive the lower pressure block to move synchronously with the output module bracket, and the hinge structure facilitates flipping the top plate and removing the PCB module after subsequent testing.

[0013] As a further improvement to the above solution, two first limiting rods are symmetrically fixedly installed on one side of the inner wall of the assembly bracket, and two second limiting rods are fixedly installed on the side of the output module bracket near the linear guide rail. Each of the two first limiting rods is fitted with a tension spring, and the other end of each of the two tension springs is fitted on the adjacent second limiting rod.

[0014] Through the above technical solution, the first limiting rod and the second limiting rod provide fixed fulcrums for the tension spring. The tension of the tension spring can pull the output module bracket back to the initial position when the test component is not subjected to external force, thereby achieving automatic reset. At the same time, the elastic force of the tension spring can balance the weight of the test component and prevent the component from falling freely and impacting the PCB module.

[0015] As a further improvement to the above solution, the same end of both second limiting rods is fitted with the inner wall of the assembly bracket to prevent the tension spring from falling off.

[0016] Through the above technical solution, the fitting structure between the second limiting rod and the inner wall of the assembly bracket can limit the stretching direction of the tension spring, preventing the tension spring from falling off the limiting rod during the extension and retraction process, and ensuring the long-term stable operation of the reset assembly.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention replaces the traditional screwdriver method of screwing in and out by setting up a quick clamp and pressure head. The clamping and disassembly of the PCB module can be completed by manually driving the quick clamp, which is convenient to operate, greatly shortens the testing and assembly time, and improves production efficiency. With the elastic buffer of the spring and the automatic reset function of the tension spring, it can ensure a tight contact between the output head and the output terminal of the PCB module, ensuring stable transmission of high current, and avoid damage to the terminal caused by rigid contact, thus reducing testing costs.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Please combine Figures 1-4This embodiment provides a high-current output fixture capable of quick clamping, including a PCB module 1. One side of the PCB module 1 is provided with a test component capable of quickly testing the current of the output terminals of the PCB module 1, and the other side of the test component is provided with a reset component that automatically resets the test component when the current test is not required.

[0022] The test assembly includes a pressure block 201 located on one side of the top of the terminal of PCB module 1. The pressure block 201 is hollow and convex. Multiple output heads 202 are provided on the bottom side of the pressure block 201. A metal rod 203 is fixedly installed at the top of each output head 202. The top of each metal rod 203 extends upward into the interior of the pressure block 201 and is fixedly installed with a metal sheet 204. A wire 205 is electrically connected to one side of each metal sheet 204.

[0023] The hollow convex pressing block 201 can stably support components such as the output head 202 and the metal rod 203. Multiple output heads 202 can be precisely connected to multiple sets of output terminals of PCB module 1 to meet the requirements of high current testing. The metal rod 203 and the metal sheet 204 form a conductive path, which, together with the wire 205, realizes current transmission and ensures stable current output during the test.

[0024] Each metal rod 203 is fitted with a spring 4, and the two ends of each spring 4 are fixedly installed to the adjacent output head 202 and the lower pressure block 201, respectively.

[0025] Spring 4 has an elastic buffering function. When the output head 202 contacts the output terminal of PCB module 1, spring 4 can compensate for the contact gap through compression, so that the output head 202 and the terminal fit tightly together, improving conductivity stability. At the same time, the rebound force of spring 4 can prevent the output head 202 from causing rigid compression to the terminal, protecting the terminal from damage.

[0026] The PCB module 1 is covered with a protective shell 5. A quick clamp 6 is fixedly installed on the top side of the protective shell 5. A pressure head 7 is fixedly installed on the pushing end of the quick clamp 6.

[0027] The protective shell 5 can protect the PCB module 1 and the internal test components, preventing external dust and impurities from affecting the test accuracy; the quick clamp 6, as the core operating component, can drive the pressure head 7 up and down by manual drive, without the need for power tools, to realize the quick clamping and disassembly of the PCB module 1, which greatly shortens the test preparation time.

[0028] The reset assembly includes a general assembly bracket 301 fixedly installed inside the protective housing 5. The general assembly bracket 301 is concave. A linear guide rail 302 is fixedly installed inside the general assembly bracket 301. An output module bracket 303 is fixedly installed on the slide of the linear guide rail 302. A top plate 304 is hinged to one side of the top of the output module bracket 303. The top plate 304 is concave. The top of the lower pressure block 201 is located inside the top plate 304 and is fixedly installed with the top plate 304.

[0029] The concave assembly bracket 301 provides a stable mounting base for the linear guide rail 302 and the output module bracket 303; the linear guide rail 302 limits the movement direction of the output module bracket 303, ensuring that it moves only in the vertical direction, avoiding misalignment caused by test component displacement; the concave top plate 304 is fixedly connected to the lower pressure block 201, which can drive the lower pressure block 201 to move synchronously with the output module bracket 303, and the hinge structure facilitates the flipping of the top plate 304 after subsequent testing to remove the PCB module 1.

[0030] Two first limiting rods 8 are symmetrically fixedly installed on one side of the inner wall of the assembly bracket 301. Two second limiting rods 9 are fixedly installed on the side of the output module bracket 303 near the linear guide rail 302. A tension spring 10 is sleeved on each of the two first limiting rods 8. The other end of each tension spring 10 is sleeved on the adjacent second limiting rod 9. The same end of each of the two second limiting rods 9 is in contact with the inner wall of the assembly bracket 301 to prevent the tension spring 10 from falling off.

[0031] The first limiting rod 8 and the second limiting rod 9 provide fixed fulcrums for the tension spring 10. The tension of the tension spring 10 can pull the output module bracket 303 back to its initial position when the test component is not subjected to external force, thus achieving automatic reset. At the same time, the elastic force of the tension spring 10 can balance the weight of the test component and prevent the component from falling freely and impacting the PCB module 1.

[0032] The implementation principle of a high-current output clamp capable of quick clamping in this application embodiment is as follows: Initially, the tension spring 10 is in a naturally stretched state, and its tension drives the output module bracket 303 to slide along the linear guide rail 302 to the top through the second limiting rod 9; under the initial positioning of its own hinge structure, the top plate 304 drives the lower pressure block 201 to be in a flipped state, and the output head 202 is away from the output terminal of the PCB module 1; the handle of the quick clamp 6 is downward, and the pressure head 7 is located at the top and does not contact the top plate 304.

[0033] When testing PCB module 1, install PCB module 1 inside the protective shell 5, and then manually flip the top plate 304. Since the top plate 304 is hinged to the output module bracket 303, the top plate 304 can rotate around the hinge point until the bottom surface of the lower pressure block 201 faces the output terminal of PCB module 1. At this time, the top plate 304 remains horizontal and the output head 202 is directly facing the terminal.

[0034] Next, pull the handle of the quick clamp 6 upwards. The pushing end of the quick clamp 6 drives the pressure head 7 to move downwards. The pressure head 7 first contacts the top of the top plate 304. Continue to pull the handle upwards. The pressure head 7 applies downward pressure to the top plate 304. The top plate 304 drives the lower pressure block 201 to move downwards synchronously.

[0035] When the pressure block 201 moves downward, it pushes the output head 202 closer to the output terminal of the PCB module 1 through the metal rod 203. At the same time, the output module bracket 303 slides vertically downward along the slide of the linear guide rail 302 under the drive of the top plate 304. The linear guide rail 302 limits the output module bracket 303 to move only in the vertical direction to avoid deviation.

[0036] After the end face of the output head 202 contacts the top surface of the output terminal, continue to pull up the handle of the quick clamp 6. The output head 202 is subjected to the reaction force of the output terminal, which compresses the spring 4 on the metal rod 203 upward, and the spring 4 undergoes elastic deformation. Until the handle of the quick clamp 6 moves to the locked position, the quick clamp 6 remains locked. At this time, the compression of the spring 4 reaches the preset value. Under the action of the spring 4's rebound force, the output head 202 is tightly pressed against the output terminal to ensure good conductive contact.

[0037] Finally, the power supply wire 205 is connected to the external test circuit. The current is transmitted through the power supply wire 205 to the metal plate 204, and then through the metal rod 203 to the output head 202, and finally input to the output terminal of the PCB module 1 to complete the high current test connection.

[0038] After the test is completed, first pull the handle of the quick clamp 6 upwards. The locking state of the quick clamp 6 is released, and the pushing end drives the pressure head 7 to move upwards. The pressure of the pressure head 7 on the top plate 304 disappears.

[0039] At this time, the tension of the tension spring 10 begins to take effect. The tension spring 10 is sleeved between the first limiting rod 8 and the second limiting rod 9. Its tension pulls the second limiting rod 9 upward, and the second limiting rod 9 drives the output module bracket 303 to slide upward along the slide of the linear guide rail 302.

[0040] When the output module bracket 303 moves upward, it drives the top plate 304 to rise synchronously. The top plate 304 pulls the lower pressure block 201, metal rod 203 and output head 202 away from the terminal of PCB module 1, and the spring 4 gradually returns to its natural state. Until the output module bracket 303 slides to the top of the linear guide rail 302, the tension spring 10 returns to its natural tension state, and the output head 202 is completely separated from the output terminal.

[0041] Finally, manually flip the top plate 304. The top plate 304 rotates around the hinge point with the output module bracket 303, causing the lower pressure block 201 to return to the initial flipped state. At this time, there is no obstruction above the PCB module 1, and the PCB module 1 can be directly removed to complete one test process.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
