Its characteristics are as follows:
1) The cover 4 of the junction box is fixed on the junction box body 1 with two screws (that is, the screws will not fall off after the cover is opened);
2) The cover is bolted with a chain 5. When the cover is opened, the chain is bolted so that the cover will not fall;
3) The cover and the junction box body are sealed with heat-resistant black rubber as the sealing ring;
4) The outlet hole is sealed with black rubber as the sealing ring 8, and then the outlet bolt 7 is pressed to clamp the connecting wire;
The splash-proof performance of the splash-proof junction box should withstand the test of artificial rain sputtering at a rainfall of 5 mm/min and a 45° angle to the horizontal for 5 minutes. During the test, the thermocouple and thermal resistance rotate along the longitudinal uranium. Then open the junction box cover for observation, no water can penetrate into the interior,
The thermocouple and thermal resistance products of the junction box with splash-proof performance can be used in the scene where water vapor splashes or is relatively humid or dusty.
