Description
技术领域technical field
本发明设计涉及一种压电传感器接头与信号线焊接固定装置，利用滑块以及弹簧压片分别压紧屏蔽信号线和压电传感器接头，解决了焊接过程中信号线和接头难以固定导致的焊接困难的问题，应用于压电测力领域，特别适用于压电传感器信号传输时，传输介质的制作。The design of the present invention relates to a welding and fixing device for piezoelectric sensor joints and signal lines, which uses sliders and spring pressure pieces to respectively press the shielded signal lines and piezoelectric sensor joints, which solves the welding problem caused by the difficulty in fixing the signal lines and joints during the welding process. Difficult problems, applied to the field of piezoelectric force measurement, especially suitable for the production of transmission media during the transmission of piezoelectric sensor signals.
背景技术Background technique
压电传感器输出的信号为电荷信号，需要用电荷放大器电荷将压电传感器输出的电荷信号转变成电压信号。而从传感器输出的高阻抗电荷信号非常容易受到干扰，为了防止微弱电荷泄露，空气中可能带电的尘土颗粒对电荷的扰动以及外界电场及磁场的干扰，所以使用低噪声屏蔽信号线传输电荷信号。信号线与压电传感器通过接头连接到一起，将信号传输到电荷放大器。由于信号线与传感器接头的焊接困难，焊接时需要一套固定信号线以及传感器接头的装置。The signal output by the piezoelectric sensor is a charge signal, and it is necessary to use a charge amplifier to convert the charge signal output by the piezoelectric sensor into a voltage signal. The high-impedance charge signal output from the sensor is very susceptible to interference. In order to prevent the leakage of weak charges, the disturbance of charges by dust particles that may be charged in the air, and the interference of external electric and magnetic fields, low-noise shielded signal lines are used to transmit charge signals. The signal line and the piezoelectric sensor are connected together through the connector, and the signal is transmitted to the charge amplifier. Due to the difficulty of welding the signal line and the sensor joint, a set of devices for fixing the signal line and the sensor joint is required during welding.
现有的线固定装置，主要采用U形凹槽和U形压块的结构。通过压杆和立杆控制U形凹槽和U形压块之间闭合和开启，无需使用辅助工具即可完成安装，且U形凹槽和U形压块在氧化和上锈的情况下不会贴合在一起，使拆卸更加方便，节省大量时间，提高工作效率。但不满足固定传感器接头的需求，因此需要设计一种方便信号线与传感器接头焊接的装置。The existing wire fixing device mainly adopts the structure of U-shaped groove and U-shaped pressing block. The closing and opening between the U-shaped groove and the U-shaped pressing block is controlled by the pressing rod and the vertical rod, and the installation can be completed without the use of auxiliary tools, and the U-shaped groove and the U-shaped pressing block are not oxidized and rusted. It will fit together, making disassembly more convenient, saving a lot of time and improving work efficiency. However, it does not meet the requirements of fixing the sensor connector, so it is necessary to design a device that facilitates the welding of the signal line and the sensor connector.
