The differential pressure sensor 4 is fixed to the mounting portion 6.
As further shown in fig. 2 and 3, the differential pressure sensor 4 is provided with a third plug connector 42. The junction box (1) further comprises a circuit board 13. The first and second connectors 2 and 3 are electrically connected to the circuit board 12, and the third connector 42 is electrically connected to the second connector 3 to transmit the signal of the differential pressure sensor 4 to the circuit board 12. The third plug 42 and the second plug 3 can be electrically connected by a cable. The signal of the differential pressure sensor 4 is transmitted to the second connector 3 via the third connector 42, then to the circuit board 12 and then to the first connector 2. The signal is transmitted to an external device through the first connector 2.
The junction box 1 includes a first housing 11 and a second housing 13 fixed together with the first housing 11. The first housing 11 and the second housing 13 are fixed together to form an accommodating space in which the circuit board 12 is placed. The shell plays a role in protecting the circuit board. The first connector 2, the second connector 3 and the mounting portion 6 may be integrated with the first housing 11, or may be fixed to the first housing 11 by assembling.

The first post portion 62 is also provided with at least one recess 623 that extends downwardly from the end 621 to the base 622. The groove 623 divides the pillar portion 62 into a first elastic portion and a second elastic portion. The first pillar portion 62 protrudes into the through-hole 411 and the end portion 621 is disposed outside the through-hole 411. The first and second elastic parts are inclined to both sides from the groove 623. When the elastic part is pressed inward, the elastic part generates an elastic force.
The bottom 622 is cylindrical and the end face of the end 621 is spherical. This configuration is advantageous in that the end 621 is formed into a spherical surface, thereby reducing resistance when the first pillar portion 62 is inserted into the through hole 411.
