When the wiring harness is energized, the external connector is inserted into the inner sides of the first connector, the second connector, and the third connector and connects to the first motor contact wire, the second motor contact wire, and the sensor connection wire. By protecting the sensor of the new energy vehicle, the sensor can be kept stable during use. In addition, this invention uses the movable arc head to slide under pressure during sensor connection, which causes the support spring to contract, so that the movable arc head drives the first contact post to contact the second contact post. At this time, the first contact post and the second contact post are energized and conductive. When the external connector becomes loose, the movable arc head moves away from the sealing seat, and the first contact post and the second contact post separate. Then, the detection circuit sends a signal to the outside to achieve the purpose of loosening monitoring. This is conducive to timely detection and elimination of faults. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figure 1 and Figure 2 This utility model provides an embodiment of an automotive sensor assembly, comprising a sensor mounting housing 1. One end of the upper part of the sensor mounting housing 1 has a second connector 4, and the other end has a first connector 3. A third connector 5 is located below the second connector 4 on the sensor mounting housing 1. Multiple rivet mounting holes 2 are provided on the outer side of the sensor mounting housing 1. A time scale 6 is provided on the surface of the sensor mounting housing 1, which is directly formed during the injection molding process. The time scale 6 allows for quick identification of product production time, batch number, and other information, providing crucial reference data in quality control, after-sales service, or product recall. A covering base 7 is fixed inside the sensor mounting housing 1, facilitating the fixed installation and protection of the covering base 7 and effectively maintaining its stability.

[0019] Please see Figures 2 to 4The bottom of the base frame 7 is provided with two motor contact mounting sleeves 8. Inside the base frame 7, there is a cable group 9. The cable group 9 consists of a first motor contact wire 10, a second motor contact wire 11, and six sensor connection wires 12. The two motor contact mounting sleeves 8 are fixedly connected to the first motor contact wire 10 and the second motor contact wire 11. The upper ends of the six sensor connection wires 12 pass through the base frame 7 and extend to the inside of the first plug-in interface 3. The first motor contact wire 10, the second motor contact wire 11, and the six sensor connection wires 12 are all made of conductive metal. The sensors can easily transmit electrical signals between multiple ports through the first motor contact wire 10, the second motor contact wire 11, and the six sensor connection wires 12.

[0020] To improve structural stability, it is preferable to integrate the base frame 7, the cable assembly 9, and the two motor contact mounting sleeves 8 into a single injection molded unit. The two motor contact mounting sleeves 8 are located inside the third connector 5. The bottom end of the base frame 7 extends to the inside of the second connector 4, and the top end of the base frame 7 extends to the inside of the first connector 3. External wiring can be quickly connected via plug-in connection through the first connector 3, the second connector 4, and the third connector 5.

[0021] Please see Figure 2 and Figure 5 A loosening monitoring unit 13 is installed on the sensor mounting housing 1. To accommodate the installation of the loosening monitoring unit 13, a mounting hole is provided on the sensor mounting housing 1. The mounting hole is a stepped hole. The loosening monitoring unit 13 is installed in the mounting hole. The loosening monitoring unit 13 includes a sealing seat 14 and a movable arc-shaped head 15. The movable arc-shaped head 15 is adapted to move towards and away from the sealing seat 14. The sealing seat 14 is threadedly connected to the large-diameter end of the mounting hole. The movable arc-shaped head 15 is movably disposed at the small-diameter end of the mounting hole and extends to the inside of the second insertion interface 4. A support spring 16 is provided between the sealing seat 14 and the movable arc-shaped head 15. The sealing seat 14 and the movable arc-shaped head 15 are respectively provided with a first contact post. Under normal conditions, the first contact post 17 and the second contact post 18 are separated by the elastic force of the support spring 16. During installation and use, the first contact post 17 and the second contact post 18 are connected to an external detection circuit (such as an indicator light circuit, a buzzer circuit, etc.). When the external connector is inserted into the second plug interface 4, a pushing force is applied to the movable arc head 15, causing the first contact post 17 and the second contact post 18 to come into contact. When the external connector becomes loose, the movable arc head 15 moves away from the sealing seat 14, and the first contact post 17 and the second contact post 18 separate. Then, a signal is sent to the outside through the detection circuit to achieve the purpose of loosening monitoring. This is conducive to timely detection and elimination of faults.

[0022] Preferably, the movable arc head 15 is connected to the first contact post 17 and the sealing seat 14 is connected to the second contact post 18 by injection molding, and the first contact post 17 and the second contact post 18 are coaxially arranged.

[0023] When using the sensor in a new energy vehicle, the rivet is passed through the rivet mounting hole 2 and the sensor mounting housing 1 is fixed inside the new energy vehicle. The surface of the sensor mounting housing 1 is provided with a first plug interface 3, a second plug interface 4 and a third plug interface 5, so that the covering frame 7 drives the first motor contact wire 10, the second motor contact wire 11 and the sensor connection wire 12 in the wiring group 9 to extend to the inside of the third plug interface 5, the second plug interface 4 and the first plug interface 3 respectively.

[0024] When powering the cable group 9, the external connector is inserted into the inner side of the first connector 3, the second connector 4, and the third connector 5, and connected to the first motor contact wire 10, the second motor contact wire 11, and the sensor connection wire 12. At this time, the movable arc head 15 is squeezed and slides inside the sealing seat 14, causing the support spring 16 to contract. This causes the movable arc head 15 to drive the first contact post 17 to contact the second contact post 18. At this time, the first contact post 17 and the second contact post 18 are connected to conduct electricity, which enables the determination of the looseness of the external connector and the sensor connection, facilitating maintenance and preventing accidents.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
