The bottom of the lower shell in the sensor housing is placed in the lower shell material clamping groove 24, the top of the lower shell is placed in the lower shell boss positioning groove 23, and the bottom of the upper shell in the sensor housing is placed in the upper shell assembling groove 22. The ultrasonic welding machine is started to drive the upper die 41 of the joint to drive the T-shaped welding pressure head 46 to press downward on the left and right sides of the upper shell of the sensor housing, driving the upper shell to vibrate rapidly and rub against the lower shell, so that the connection part between the upper shell and the lower shell melts locally to connect the two.

[0039] The above-mentioned assembling lower die module 2 is placed in the center of the welding workbench 1. The assembling lower die module 2 includes: a lower die base 21, an upper shell assembling groove 22, a lower shell boss positioning groove 23, and a lower shell material clamping groove 24. Among them, the lower die base 21 is placed in the center of the top of the welding workbench 1. The lower die base 21 is in an inverted T shape. An upper shell assembling groove 22 is opened in the center of the top of the lower die base 21. A lower shell boss positioning groove 23 is opened at the bottom of the upper shell assembling groove 22. The upper shell assembling groove 22 and the lower shell boss positioning groove 23 are circular grooves. The upper shell assembling groove 22 and the lower shell boss positioning groove 23 are coaxially arranged. The inner diameter of the upper shell assembling groove 22 is larger than the inner diameter of the lower shell boss positioning groove 23. A lower shell material clamping groove 24 is longitudinally opened in the center of the top of the welding workbench 1. The lower shell material clamping groove 24 is a square groove. The groove width of the lower shell material clamping groove 24 is smaller than the inner diameters of the upper shell assembling groove 22 and the lower shell boss positioning groove 23. The groove depth of the lower shell material clamping groove 24 is larger than the groove depths of the upper shell assembling groove 22 and the lower shell boss positioning groove 23.

Installation rotating rods 45 are inserted into the second keyways 44. The installation rotating rods 45 are more convenient for exerting force and rotating when the welding pressure-applying upper die module 4 is installed. After the upper die 41 for connection is installed on the ultrasonic welding machine, the installation rotating rods 45 need to be removed. The T-shaped welding pressure head 46 is located below the upper die 41 for connection. A relief square groove 47 is opened in the middle of the bottom of the T-shaped welding pressure head 46. The groove diameter of the relief square groove 47 is the same as that of the lower shell material clamping groove 24. The bottom width of the T-shaped welding pressure head 46 is greater than the inner diameter of the upper shell assembly groove 22 and less than the width of the top of the lower die base 21.
