[0002] A display instrument is installed in the car to show the battery capacity, vehicle speed, and whether the headlights and turn signals are on, etc. The display instrument needs to be connected to the vehicle's control panel via a wiring harness. One end of the wiring harness needs to be soldered to the circuit board inside the display instrument, and the other end of the wiring harness is equipped with a wiring harness connector, which is plugged into the vehicle's main control line.

[0003] Existing display instrument wiring harnesses are typically covered with simple protective sleeves, but the interfaces between the wiring harness and the connectors lack adequate protection. Frequent use leads to bending, which easily causes wear and tear, resulting in poor contact, short circuits, and a short lifespan. Therefore, this paper proposes a display instrument wiring harness assembly that provides protection at the interfaces, preventing bending and wear damage. Furthermore, it allows for real-time temperature monitoring of the wiring harness, facilitating timely maintenance and replacement by workers, and extending its service life.

The temperature control detector is installed on the top of the upper fixing cover by screws. The temperature control detector and a small storage battery are respectively installed on one side of the upper fixing cover. Long bolts are inserted through the reserved threaded holes at the center of both sides of the upper and lower fixing covers.

[0008] Based on the above scheme and as a preferred option: mounting plates are provided on both sides of the fixed frame, and a bolt is used to connect the mounting plate to the wiring head through a reserved opening on one side.

[0009] Based on the above scheme and as a preferred option: small telescopic rods are provided on both sides inside the fixed frame. The driving end of the small telescopic rods is connected to the arc-shaped pressure plate by screws, and an anti-slip pad is attached to one side of the arc-shaped pressure plate.

[0010] Based on the above scheme and as a preferred option: the top of the protective sleeve has an insertion hole, and the protective sleeve is wrapped with an insulating sleeve and multiple sets of connecting wire harnesses. The two ends of the connecting wire harnesses are electrically connected to the output end of the connector through wires.

[0011] Based on the above scheme and as a preferred embodiment: the bottom probe of the temperature controller is inserted through the socket and in contact with the connecting wire harness; the input terminals of the temperature controller and the alarm are electrically connected to the output terminal of the small storage battery through power cords; and the output terminal of the temperature controller and the other input terminal of the alarm are electrically connected through wires.

[0012] Based on the above scheme and as a preferred option: long bolts are respectively fitted into the reserved threaded holes on both sides of the upper and lower fixing covers, and the bottom periphery of the long bolts is threadedly connected to the nuts.

[0013] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0014] This utility model discloses a display instrument connection harness assembly. Multiple sets of connection harnesses are passed through a fixed frame. A small telescopic rod pushes an arc-shaped pressure plate to press the two sides of the connection harnesses together, preventing the connection harnesses from sliding within the fixed frame and causing wear on their surface. It also provides some protection for the front end of the connection harness where a protective sleeve is wrapped.

[0015] This utility model discloses a display instrument connection harness assembly. The probe of the temperature control detector passes through a reserved opening on the surface of the insulating sleeve and contacts the surface of the connection harness. A small storage battery supplies power to the temperature control detector and the alarm via a wire. The temperature of the connection harness can be detected in real time.

[0026] Multiple sets of connecting wire harnesses 7 are passed through the fixed frame 2. The arc-shaped pressure plate 5 is pushed by the small telescopic rod 4 to press the two sides of the connecting wire harnesses 7 to prevent the connecting wire harnesses 7 from sliding in the fixed frame 2 and causing wear on its surface. It also provides some protection for the front end of the connecting wire harnesses 7 where the protective sleeve 9 is wrapped.

[0028] After the protective sleeve 9 wraps around multiple sets of connecting wire harnesses 7, the probe of the temperature control detector 13 passes through the reserved opening on the surface of the insulating sleeve 8 and contacts the surface of the connecting wire harnesses 7. The small storage battery 14 outputs power to the temperature control detector 13 and the alarm 15, which can detect the temperature of the connecting wire harnesses 7 in real time. When the real-time temperature is too high, it will transmit to the alarm 15 to sound a warning sound, so as to remind personnel to check in time, thereby reducing the probability of accidents.

[0029] To provide some protection for both ends of the connecting wire harness, as exemplarily shown in Figures 1 and 2, this utility model also includes mounting plates 3 on both sides of the fixing frame 2, with a pre-reserved opening on one side of the mounting plate 3 connected to the connector 1 by bolts.

[0030] In use, the fixing frame 2 is connected to the connector 1 by passing bolts through the mounting holes of the mounting plate 3. This can protect both ends of the connecting wire harness 7 and facilitate the connection of the connector 1 to both ends of the connecting wire harness 7, making it convenient for workers to carry out maintenance and replacement.

[0035] As exemplarily shown in Figures 1, 3, and 4, the present invention further includes a bottom probe portion of the temperature control detector 13 that penetrates the socket 10 and contacts the connecting wire harness 7. The input terminals of the temperature control detector 13 and the alarm 15 are electrically connected to the output terminals of the small storage battery 14 via power cords. The output terminal of the temperature control detector 13 and the other input terminal of the alarm 15 are electrically connected via wires.

[0036] When in use, the protective sleeve 9 wraps around multiple sets of connecting wire harnesses 7, and the probe of the temperature control detector 13 contacts its surface. When the real-time temperature is too high, it will transmit the signal to the alarm 15 to sound an alarm, so as to remind personnel to check in time and reduce the probability of accidents.
