Description

Technical Field

[0001] This application relates to the field of connector programming boards, and in particular to a connector data programming board. Background Technology

[0002] In the field of electronic equipment manufacturing, connectors are key components for achieving circuit connections, and the programming of their internal integrated chips (ICs) is an important production step. In existing technologies, connector data programming typically involves a programming board that enables signal interaction between the computer and the connector, burning specific data into the connector IC.

[0003] Currently, connector data programming boards on the market face several pressing issues in practical applications. Firstly, power management module design flaws exist. Traditional programming boards often directly utilize external power input, lacking efficient voltage reduction and filtering devices, leading to unstable input voltage. This makes them susceptible to power grid fluctuations or external electromagnetic interference, causing abnormal IC power supply during programming and affecting the accuracy and stability of the programmed data. Secondly, signal transmission path design is not optimized. Signal switching and anti-interference capabilities between the signal input interface and the programming interface are insufficient, easily resulting in signal attenuation or distortion during high-frequency data transmission, reducing programming efficiency and success rate. Furthermore, the interface layout of existing programming boards is poorly designed. The distribution of power interfaces, signal input interfaces, and programming interfaces lacks systematic planning, leading to interference between connecting cables during operation. This not only affects the convenience of device connection but may also cause programming interruptions due to poor wiring contact. Utility Model Content

[0004] The purpose of this application is to provide a connector data programming board with stable power supply, efficient signal processing capabilities and reasonable structural layout, so as to solve the problems of unstable voltage, low signal transmission reliability and unreasonable interface layout in the prior art, which have become technical problems that urgently need to be solved by those skilled in the art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A connector data programming board includes a programming board body. A signal input interface is provided near the front of the programming board surface for connecting to a computer. A first programming interface is provided near the rear of the programming board surface for connecting a connector. A power interface is provided to the left of the signal input interface, and a step-down converter is provided behind the power interface. A filter is provided to the left of the first programming interface, and an analog switch is provided behind the signal input interface. The power interface is connected to the step-down converter, the step-down converter is connected to the filter, the signal input interface is connected to the analog switch, and the analog switch is connected to the first programming interface.

[0007] Furthermore, a second programming interface is provided on the front side of the first programming interface.

[0008] Furthermore, the second programming interface is connected to an analog switch.

[0009] Furthermore, the second programming interface is connected in parallel with the first programming interface.

[0010] Furthermore, an LED indicator is provided on the right side of the first programming interface.

[0011] Furthermore, the analog switch includes a low-frequency input range, a medium-frequency input range, and a high-frequency input range.

[0012] Furthermore, the programming board body is also provided with a power supply reserved solder joint.

[0013] Furthermore, the filter includes a capacitor and a resistor connected in parallel.

[0014] Furthermore, the capacitance value of the capacitor is 50-200μF.

[0015] Furthermore, the resistance value of the resistor is 5-20Ω.

[0016] The beneficial effects of this application are as follows:

[0017] (1) This application achieves precise control of the input power by integrating a multi-stage power processing module with a step-down converter and a filter on the back side of the power interface; the step-down converter can stably convert the external input non-adaptive voltage into the rated operating voltage according to the actual power supply requirements of the programming board and connector IC, avoiding IC damage or programming errors caused by excessively high or low voltage; the filter can effectively filter out high-frequency noise and electromagnetic interference mixed in the power line, providing a clean and stable DC power supply for the IC, eliminating the problem of programming data distortion caused by power fluctuations from the hardware level, and significantly improving the programming success rate.

[0018] (2) An analog switch is set between the signal input interface and the first programming interface to construct a controllable signal transmission channel. The analog switch can turn the signal transmission path on or off in real time according to the programming command to avoid signal crosstalk in the non-programming state. At the same time, it supports time-division multiplexing of multi-channel signals and reserves hardware interfaces for subsequent expansion of multiple programming interfaces. By designing the analog switch and filter in a coordinated manner, a dual anti-interference system for power supply and signal is formed. During high-frequency data transmission, signal attenuation and phase distortion are effectively suppressed, ensuring accurate bidirectional interaction of instructions and data between the computer and the connector IC. The programming efficiency is improved by more than 30% compared with the traditional solution.

[0019] (3) The front signal input interface of this application is connected to the computer, and the rear first programming interface is connected to the connector, forming a straight signal flow of "front input-rear output", reducing signal loss caused by circuit detour; the power interface and signal input interface are set in separate areas, and the power module on the left side and the signal processing module on the right side are physically isolated, reducing the impact of power electromagnetic noise on signal transmission; modular integrated design: core components such as step-down transformers, filters, and analog switches are arranged close to their corresponding interfaces, shortening the internal trace length, reducing the parasitic capacitance / inductance effect of the PCB board, and facilitating component replacement and fault diagnosis during later maintenance.

[0028] The programming board body 1 houses all functional components and provides the physical transmission medium for signals and power. It uses an FR-4 circuit board, integrating the signal transmission layer, power layer, and ground layer, and measures 100mm × 80mm.

[0029] The first programming interface 3 enables physical and signal connection between the programming board and the connector, ensuring low impedance and high reliability of data transmission; the pin-type interface (20 pins) is gold-plated and corresponds one-to-one with the IC pins of the connector, supporting precision connection with a 0.5mm pitch.

[0030] Analog switch 7 switches the input signal frequency according to the connector IC specifications to solve the problem of programming failure under high frequency interference (such as improving the programming success rate by 30% in low frequency mode); it includes a three-position toggle switch, position 1 is low frequency input mode (≤1MHz), position 2 is medium frequency mode (1-10MHz), and position 3 is high frequency mode (≥10MHz), with built-in ESD electrostatic protection.

[0031] Step-down converter 5 provides a stable power supply for the programming process, supports a wide voltage input, and is compatible with different computer models and power adapters. It uses a DC-DC step-down chip (such as LM2596) with an input voltage range of 9-24V and dual output voltages of 5V / 3.3V, achieving an efficiency of ≥90%.

[0032] Filter 6 filters out high-frequency noise in the power supply (such as ripple ≤ 50mV) to avoid IC programming errors caused by voltage fluctuations. It consists of a π-type filter circuit composed of a 100μF electrolytic capacitor and a 10Ω resistor, connected in parallel between power interface 4 and ground.

[0033] In one embodiment, a second programming interface 8 is provided on the front side of the first programming interface 3. The second programming interface 8 is a reserved expansion port to support simultaneous programming of dual ICs.

[0034] In one embodiment, the second programming interface 8 is connected to the analog switch 7.

[0035] In one embodiment, the second programming interface 8 is connected in parallel with the first programming interface 3.

[0036] In one embodiment, an LED indicator 9 is provided on the right side of the first programming interface 3 to provide visual feedback on the programming status and reduce human error (such as green being off when programming fails); the red and green dual-color LEDs indicate the power supply status (red indicates power on / off, and green flashing indicates programming progress (1Hz flashing represents normal programming).

[0037] In one embodiment, the analog switch 7 includes a low-frequency input mode, a medium-frequency input mode, and a high-frequency input mode. The three modes of the analog switch 7 correspond to low-frequency (≤1MHz), medium-frequency (1-10MHz), and high-frequency (≥10MHz) inputs, respectively, and the signal transmission rate is different in each mode.

[0038] In one embodiment, the programming board body 1 is also provided with a power supply reserved solder joint 10.

[0039] In one embodiment, filter 6 includes a capacitor and a resistor connected in parallel.

[0040] In one embodiment, the capacitance value of the capacitor is 50-200μF.

[0041] In one embodiment, the resistance value of the resistor is 5-20Ω.

[0042] The connector data programming board of this application operates on the principle of coordinated design of power processing and signal transmission, as follows:

[0043] The power supply is input through the power interface 4 on the left. First, the non-compatible voltage (such as 5V-24V) is converted by the step-down converter 5 into the rated operating voltage (such as 3.3V / 5V) required by the programming board and connector ICs. The voltage output from the step-down converter 5 is filtered by the rear filter 6 to remove high-frequency noise and electromagnetic interference, forming a clean and stable DC power supply, which provides reliable power to the components of the programming board and connector ICs.

[0044] The front signal input interface 2 (such as USB / HDMI) connects to the computer to receive programming data and control commands. The electrical signal from the signal input interface 2 is controlled by the rear analog switch 7 for on / off switching and path switching, and is only turned on to the first programming interface 3 when a programming command is triggered. In the on state, the analog switch 7 transmits the computer signal to the rear first programming interface 3, through which it physically connects to the connector to program the data into the connector's internal IC. The filter 6 synchronously suppresses the interference of power fluctuations on signal transmission, and the analog switch 7, in conjunction with the filter circuit, reduces signal attenuation, ensuring the accuracy of the programmed data.

[0045] The power interface 4 and signal input interface 2 are separated into two zones. Components such as the step-down converter 5, filter 6, and analog switch 7 are integrated in a modular fashion, shortening internal wiring and reducing power supply noise interference with signals. The programming board only activates signal transmission via analog switch 7 when it receives a computer command, and maintains low-power standby when not in operation, improving safety and energy efficiency.

[0046] This working principle achieves stable power supply and accurate data programming for the connector IC through hardware collaboration between the power processing module and the signal control module, solving problems such as voltage fluctuation and signal distortion in existing technologies.

[0047] The embodiments described above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
