For example, CN216055316U discloses a high-temperature and high-voltage multi-line terminal block, including a substrate with a first through hole and a second through hole on one side. A conductive post passes through the first through hole, and a power post passes through the second through hole. A sensor is mounted on the conductive post, a locking block is located below the sensor, and a first encapsulation is located below the locking block. A collar is mounted on the power post, and a second encapsulation is located below the collar. A pressure-reducing plate is located within the second encapsulation. This high-temperature and high-voltage multi-line terminal block achieves effective heat dissipation and dual heat resistance by incorporating a heat insulation plate, a heat dissipation plate, and heat dissipation channels. The pressure-reducing plate, buffer layer, and wear-resistant plate protect the conductive post and power post from damage, extending the device's service life. The first encapsulation, second encapsulation, and locking block facilitate the installation and removal of the conductive post and substrate, the power post and second through hole, and the sensor and conductive post.
