Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a lead frame for filter testing. Background Technology

[0002] A filter is a frequency-selective device that allows specific frequency components of a signal to pass through while greatly attenuating other frequency components. By utilizing this frequency-selective function of filters, interference noise can be filtered out or spectrum analysis can be performed. In other words, any device or system that allows specific frequency components of a signal to pass through while greatly attenuating or suppressing other frequency components is called a filter. A filter is a device that filters waves.

[0003] A filter test lead frame is a special wire structure or support device used to connect filters to test equipment. Its core function is to ensure the stable transmission of test signals, thereby reducing the impact of external interference on test results.

[0004] A current filter test lead frame has the following shortcomings:

[0005] Existing filter test lead frames have limitations. Insufficient clamping force can cause filter leads to displacement or loosening during testing, affecting the accuracy and repeatability of test results. Excessive clamping force can damage filter leads. Furthermore, relying solely on manual lead handling is inefficient and inconsistent, impacting the stability and reliability of test data. This can lead to lead connection position deviations, poor electrical connections, unstable signal transmission, or even prevent normal testing. Utility Model Content

[0006] This invention proposes an adaptive lead frame assembly, in which two electric cylinders drive the clamps to clamp the filter wires in opposite directions, which can keep the filter wires in a fixed and stable position. Furthermore, the spring between the clamps and the electric cylinders can buffer and dampen shocks and make adaptive adjustments, thereby effectively solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a filter test lead frame, comprising an adaptive lead frame assembly, a support base, and a fixed base, wherein the adaptive lead frame assembly is installed on the top of the support base;

[0008] The adaptive lead frame assembly includes two electric cylinders, each with a connecting piece sleeved on its shaft end. The two electric cylinders convert electrical energy into mechanical energy to drive the two connecting pieces to perform linear motion. The outer walls of the two connecting pieces are bolted with support pieces, and the outer walls of the two support pieces are elastically connected with three springs. Each set of three springs is elastically connected with a clamp on its outer wall.

[0009] Preferably, the adaptive lead frame assembly also includes two slide rails, each with a servo electric cylinder installed at both ends of its inner surface wall. Each pair of servo electric cylinders has a roller connected to its shaft end, and two pulleys are fixedly installed at both ends of the outer wall of each roller.

[0010] Preferably, a filter housing is fixedly installed on the top of the support base, and a set of connection ports is installed on one side of the outer wall of the filter housing.

[0011] Preferably, the top of the filter housing has a heat dissipation vent, and a set of support frames is fixedly connected to the top of the fixed base.

[0012] Preferably, a support plate is bolted to the top of a set of support frames, and the top of the fixed base is connected to the bottom of two servo cylinders and one electric cylinder, respectively.

[0013] Preferably, the outer surfaces of the eight pulleys are slidably connected to the inner wall of a corresponding slide rail, the top of an electric cylinder is fixedly connected to the bottom of a support plate, and the bottoms of the two slide rails are bolted to the top of a fixed base.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, an adaptive lead frame assembly is provided. Two electric cylinders drive the clamps to clamp the filter leads in opposite directions, ensuring a fixed and stable position. The springs between the clamps and the electric cylinders provide cushioning, shock absorption, and adaptive adjustment, reducing the shaking or displacement of the filter leads caused by external forces or minor variations in their own size. This helps ensure a stable connection between the lead and the filter pins, preventing problems such as loosening or poor contact due to changes in filter position, thus guaranteeing the reliability of the electrical connection and reducing signal transmission interruptions or instability. Simultaneously, the rollers slide in the groove, allowing for flexible height adjustment to accommodate filter leads of different sizes. During testing, the lead maintains appropriate tension and angle when connecting the filter and testing equipment, preventing uneven stress due to excessive bending, stretching, or twisting. The stable clamp system prevents excessive local stress on the lead due to filter movement during testing, extending lead lifespan and reducing the probability of test failures caused by lead damage.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, according to Figures 1-6 As shown, this utility model provides a technical solution: a filter test lead frame, including an adaptive lead frame assembly 7, a support base 1, and a fixed base 4, wherein the adaptive lead frame assembly 7 is installed on the top of the support base 1;

[0026] The adaptive lead frame assembly 7 includes two electric cylinders 701. Each of the shaft ends of the two electric cylinders 701 is fitted with a connector 702. The two electric cylinders 701 convert electrical energy into mechanical energy to drive the two connectors 702 to make linear motion. The outer walls of the two connectors 702 are bolted with support members 703. The outer walls of the two support members 703 are elastically connected with three springs 704. The outer walls of every three springs 704 are elastically connected with clamps 705.

[0027] The overall effect achieved by embodiment 1 is as follows: By pre-setting the above components, a complete adaptive lead frame assembly 7 is formed. First, connecting parts 702 are sleeved on the shaft ends of the two electric cylinders 701, and support parts 703 are bolted to the outer walls of the connecting parts 702. Three springs 704 are elastically connected to the outer walls of the two support parts 703, and clamps 705 are elastically connected to the outer walls of every three springs 704. The two electric cylinders 701 convert electrical energy into mechanical energy, which drives the two clamps 705 to move linearly through the two connecting parts 702 and the two support parts 703. At the same time, the springs 704 can play a buffering role when the clamps 705 clamp the lead wire. When the electric cylinders 701 push the clamps 705 to quickly approach the lead wire and apply clamping force, the springs 704 can play a buffering role when the clamps 705 clamp the lead wire. Spring 704 can absorb some of the impact force, preventing hard collisions between clamp 705 and the wire, thus protecting the wire from damage by instantaneous impact. An adaptive wire holder assembly 7 is provided, with two electric cylinders 701 driving clamps 705 to clamp in opposite directions, which can keep the filter wire in a fixed and stable position. The spring 704 between clamp 705 and electric cylinder 701 can buffer shock and adaptively adjust, thereby reducing the shaking or displacement of the filter wire caused by external force or its own slight differences. This helps to ensure that the connection between the wire and the filter pin remains stable, avoiding problems such as loose wires and poor contact caused by changes in the filter position, ensuring the reliability of the electrical connection, and reducing the occurrence of signal transmission interruption or instability.

[0028] Example 2, according to Figures 1-6 As shown, the adaptive lead frame assembly 7 also includes two slide rails 706. Servo cylinders 707 are installed at both ends of the inner surface of each slide rail 706. A roller 708 is connected to the shaft end of each pair of servo cylinders 707. Two pulleys 709 are fixedly installed at both ends of the outer wall of each roller 708. A filter housing 2 is fixedly installed on the top of the support base 1. A set of connection ports 3 is installed on one side of the outer wall of the filter housing 2. A heat dissipation vent 8 is opened on the top of the filter housing 2. A set of support frames 5 is fixedly connected to the top of the fixed base 4. A support plate 6 is bolted to the top of the set of support frames 5. The top of the fixed base 4 is connected to the bottom of the two servo cylinders 707 and one electric cylinder 701, respectively. The outer surfaces of the eight pulleys 709 are slidably connected to the inner surface of the corresponding slide rail 706. The top of one electric cylinder 701 is fixedly connected to the bottom of the support plate 6. The bottoms of the two slide rails 706 are bolted to the top of the fixed base 4.

[0029] The overall effect of Embodiment 2 is as follows: By pre-setting the above components, servo cylinders 707 are first installed at both ends of the inner surface of the two slide rails 706, and the shaft ends of every two servo cylinders 707 are connected to rollers 708. Two pulleys 709 are fixedly installed at both ends of the outer wall of the two rollers 708. The four servo cylinders 707 convert electrical energy into mechanical energy to drive a roller 708 to move linearly on the inner surface of the slide rail 706. The roller 708 slides in the slide rail 706, and its height can be flexibly adjusted to accommodate filter wires of different sizes. During the test, the wire can maintain appropriate tension and angle when connecting the filter and the test equipment, avoiding uneven force on the wire due to excessive bending, stretching or twisting. The roller 708 can be accurately adjusted to a suitable height to ensure that the connection position between the wire and the filter and the test equipment is accurate, thereby improving the accuracy and consistency of the test.

[0030] The working principle of the entire equipment is as follows: During the installation phase: Place the components to be assembled in a safe area to provide a safe assembly environment for subsequent assembly. First, determine the specific installation position of the support base 1. Then, fix the support base 1 in place with bolts. Next, fix the filter housing 2 to the top of the support base 1 with bolts, and install a set of connection ports 3 on one side of the outer wall of the filter housing 2. A heat dissipation vent 8 is opened on the top of the filter housing 2. Next, a set of support frames 5 are fixedly connected to the top of the fixed base 4, and a support plate 6 is bolted to the top of the support frames 5. The bottom of the support plate 6 is bolted to the top of one of the electric cylinders 701. Finally, the top of the fixed base 4 is connected to two servo electric cylinders 707... The bottom of one electric cylinder 701 is connected, and the shaft ends of two electric cylinders 701 are fitted with connecting parts 702. Supporting parts 703 are bolted to the outer wall of the connecting parts 702. Three springs 704 are elastically connected to the outer wall of the two supporting parts 703. Clamps 705 are elastically connected to the outer wall of each of the three springs 704. Servo electric cylinders 707 are installed at both ends of the inner wall of the two slide rails 706. The shaft ends of each pair of servo electric cylinders 707 are connected to rollers 708. Two pulleys 709 are fixedly installed at both ends of the outer wall of the two rollers 708. The bottom of the two slide rails 706 is bolted to the top of the fixed base 4. The outer surfaces of the eight pulleys 709 are slidably connected to the inner wall of the corresponding slide rail 706.

[0031] The working principle of this device is as follows: The working stage is as follows: After all components are assembled, check whether each component is properly installed and fixed to ensure there is no looseness. Once confirmed, connect the required power supply to an external power source. First, fully connect the test equipment's wires to the filter. Then, activate the two electric cylinders 701 through the external power supply. The two electric cylinders 701 convert electrical energy into mechanical energy, which drives the two clamps 705 to move linearly through the two connecting parts 702 and the two supporting parts 703, firmly fixing the wires between the two clamps 705. Simultaneously, the spring 704 acts as a buffer when the clamps 705 hold the wires. An adaptive wire support assembly 7 is provided, with the two electric cylinders 701 driving the clamps 705 to clamp in opposite directions, ensuring the filter wires remain in a fixed and stable position. Furthermore, the spring 704 between the clamps 705 and the electric cylinders 701 can buffer, dampen, and adaptively adjust, thereby reducing the impact of external forces or self-damage on the filter wires. The slight variations in wire size and the resulting wobbling or displacement help ensure a stable connection between the wire and the filter pins, preventing issues such as loose wires or poor contact due to changes in filter position. This guarantees the reliability of the electrical connection and reduces signal transmission interruptions or instability. Furthermore, an external power supply activates four servo cylinders 707, which convert electrical energy into mechanical energy to drive a roller 708 in a linear motion relative to the inner wall of a slide rail 706. The roller 708 slides within the slide rail 706, allowing for flexible height adjustment to accommodate filter wires of different sizes. During testing, this ensures the wire maintains appropriate tension and angle when connecting to the filter and testing equipment, preventing uneven stress caused by excessive bending, stretching, or twisting. It also allows for precise adjustment of the roller 708 to the appropriate height, ensuring accurate connection between the wire, filter, and testing equipment, thereby improving testing accuracy and consistency.
