It piece and effectively can prevent shell fragment from rotating, can also improve installation accuracy.By ceramic bottom board 2 and shell fragment soldering one, pricker
Weldering can guarantee that the high bond strength of ceramic bottom board 2 and shell fragment, and ceramics insulating properties ensure auxiliary stationary contact bridge 6 with
The insulation safety of the dynamic tactile bridge 5 of auxiliary, the upper end metal that the structure of shell fragment can not only preferably with the mounting hole 12 at wire
Layer conducting, while the resilience of the adhesive moment of relay 100 can be reduced, improves the job stability of relay 100.
As shown in Figures 4 to 7, the upper end of shell 1 is provided with two mounting holes 12, the upper and lower end face of mounting hole 12 and peace
Dress hole 12 inner surface be equipped with metal level, by wire and the soldering of shell 1 one, the upper and lower surface of mounting hole 12 and
Metal level in mounting hole 12 can preferably ensure the accuracy connected, and prevent from also normally detecting conducting when wire from misplacing.
Relay 100 is in release conditions as shown in figure 5, contact 21 and binding post 11 are separated, and relay 100 is not
Conducting, can detect the circuit to conductor signal and be not turned on, it was demonstrated that relay 100 is not turned on.When relay 100
As shown in fig. 6, contact 21 and binding post 11 are contacted after the start-up operation adhesive of pushing mechanism 4, shell fragment and shell 1, lead
Line is turned on, and the normal work of relay 100 can detect the line conduction, it was demonstrated that relay 100 is normal to conductor signal
Work.
The present invention carries out overload protection using fuse 3, effectively avoids that load current is too high or short circuit is caused
Danger.The present invention improves the use longevity of relay 100 using the rapid arc extinguishing of arc-chute on ceramic bottom board 2
Life.The present invention insulated high-low pressure using ceramic bottom board 2, it is to avoid the danger that relay 100 punctures.Comparatively speaking,
