Embodiment Construction
[0036] The present invention will be further described in detail below with reference to the accompanying drawings.
[0037] Such as Figure 1 to 2 As shown, a wheel speed sensor chip module 100 provided in the first embodiment of the present invention is provided, and the wheel speed sensor chip module 100 is mounted on a wheel of the vehicle for detecting the wheel speed of the vehicle in real time. The wheel speed sensor chip module 100 includes a chip 10, a first terminal 20, a second terminal 30, a first gold wire (not shown), the second gold (not shown), a third electrical connector (not shown) Show) and insulating housing 40. The first gold wire is connected between the chip 10 and the first terminal 20 to form a first connector, in particular, one end of the first gold wire is soldered to the chip 10, and the other end of the first gold wire is welded to the first terminal 20. The second gold wire is coupled between the chip 10 and the second terminal 30 to form a second co...
