AI Technical Summary
When installing thermistors using existing through-wall terminals, the thermistor probes are easily damaged and poor contact occurs, leading to temperature measurement failure.
Design a through-wall terminal with a thermistor installed. By setting a plastic-coated part on the copper busbar, the thermistor is placed into the notch of the plastic-coated part and held tightly against the copper busbar by a fixing sleeve. Combined with a sealing ring and a glue injection groove, a stable contact and seal are achieved.
It achieves good contact between the thermal probe and the copper busbar, ensuring accurate temperature measurement, and provides a sealed and waterproof effect, avoiding problems such as damage to the thermal probe and poor contact.

Abstract
Claims
1. A wall bushing provided with a thermistor, characterized in that include: The device comprises a terminal housing, a copper busbar, and a thermistor. The terminal housing has mounting holes, and the copper busbar has a plastic-coated component with notches and grooves. The thermistor's thermistor probe is inserted into the notches, and the signal line portion of the thermistor is inserted into the grooves. A fixing sleeve is fitted onto the plastic-coated component, which holds the thermistor probe tightly against the copper busbar. The plastic-coated component is inserted into the mounting holes.
2. The thermal sensor-equipped wall bushing according to claim 1, wherein The upper end of the copper busbar is connected to a wiring bolt and a nut.
3. The thermal sensor-equipped wall bushing according to claim 1 or 2, wherein The sealing groove on the plastic-coated part is fitted with a sealing ring, and the sealing ring makes sealing contact with the side wall of the mounting hole.
4. The thermal sensor-equipped wall bushing according to claim 1, wherein The mounting hole consists of an injection groove and a through hole at the bottom of the injection groove. The injection groove is filled with sealant that covers the upper part of the plastic-coated part and the thermal probe.
5. The thermal sensor-equipped wall bushing according to claim 4, wherein The edge of the plastic-coated part in the middle contacts the bottom surface of the injection groove.
6. The thermal sensor-equipped wall bushing according to claim 1, wherein The plastic-coated part is provided with an annular groove, and the fixing sleeve is fitted inside the annular groove.
7. A through-wall terminal with a thermistor installed according to claim 5, characterized in that, The plastic-coated part is provided with snap-fit grooves on its left and right sides, and the inner wall of the mounting hole is provided with snap-fit heads that engage with the snap-fit grooves.
8. The thermal sensor-equipped wall bushing according to claim 1, wherein The bent portion at the left end of the copper busbar is inserted into the slot inside the terminal housing and is fixed to the terminal housing by screws.
