[0027] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0028] Example 1:

[0029] like Figures 1 to 6As shown, this embodiment provides a protective cover for a temperature sensor and wiring harness connector of a commercial vehicle retarder, including two covers that can be mated and clamped together; the two covers can be tightly attached to the outside of the temperature sensor 1 and wiring harness connector 2 of the retarder in the circumferential direction, and the inner sidewall shape of the complete cover formed by the mating of the two covers matches the shape of the temperature sensor 1 and wiring harness connector 2 so that they will not rotate relative to each other, and both ends of the covers are provided with axial limiting rings that can clamp the temperature sensor 1 and wiring harness connector 2 in the axial direction so that they will not move relative to each other in the axial direction.

[0030] The shape and structure of the cover are designed based on the structure of the retarder temperature sensor and the wiring harness connector, so that it can fit tightly to the appearance of the temperature sensor and the wiring harness connector. The upper and lower ends of the cover are fixed locking structures that match the shape of the temperature sensor and the wiring harness connector. When the cover covers the temperature sensor and the wiring harness connector, the protrusions or grooves on the cover correspond perfectly with the protrusions or grooves on the temperature sensor and the wiring harness connector and lock them tightly. There will be no relative rotational movement between the cover and the temperature sensor and the wiring harness connector in the circumferential direction. The upper and lower ends of the cover are tightened and fitted with one end face of the temperature sensor and one end face of the wiring harness sensor, respectively, to firmly fix and lock the wiring harness sensor and the temperature sensor. The wiring harness connector cannot move axially, thus achieving fixation.

[0031] One of the covers has a male end matching latch, serving as the male end 31 of the protective cover; the other cover has a female end matching latch, serving as the female end 32 of the protective cover. After the two covers are placed over the temperature sensor 1 and the wiring harness connector 2, the protrusion of the male end matching latch engages with the slot of the female end matching latch, thus securing the protective cover 3, temperature sensor 1, and wiring harness connector 2 in a fixed and locked manner. This reliably connects the temperature sensor and wiring harness connector, preventing loosening or detachment due to road bumps or vibrations, and preventing axial loosening and damage to the sensor. It also avoids damage to the sensor and wiring harness connector during driving or loading, protecting the normal operation of the retarder.

[0032] After the above components are assembled, as follows Figure 1 and 2 As shown, the retarder temperature sensor and wiring harness connector are assembled without a protective cover. Figure 3 As shown, the protective cover and its male and female ends are as follows: Figures 4 to 6 As shown.

[0033] The male end matching latches are located on the two mating edges of the housing, and the multiple male end matching latches on each mating edge are aligned with the positions of the temperature sensor 1 and the wire harness connector 2, respectively; the female end matching latches are located on the two mating edges of the housing, and correspond one-to-one with the multiple male end matching latches.

[0034] Temperature sensor 1 includes a hexagonal outer section 11 and a rotary mating section 12; in other embodiments, for other sensors, such as pressure sensors, the outer shape may be other shapes.

[0035] The wire harness connector 2 includes a rotating housing 21 and an internal pin connector 22; the internal pin connector 22 can be connected and engaged with the pins of the temperature sensor 1, and the rotating housing 21 of the wire harness connector 2 rotates on the rotating engagement section 12 of the temperature sensor 1.

[0036] The covers are connected axially in sequence as follows: temperature sensor end face tensioning assembly surface 131, temperature sensor appearance clamping fitting section 132, connector rotating housing axial clamping fitting section 232, and connector rotating housing end face tensioning assembly surface 231; the temperature sensor end face tensioning assembly surfaces 131 of the two covers form an axial limiting stop ring at one end of the cover; the connector rotating housing end face tensioning assembly surfaces 231 of the two covers form an axial limiting stop ring at the other end of the cover.

[0037] The temperature sensor end face tensioning mounting surface 131 is tightly attached to the end face of the hexagonal outer section 11; in other embodiments, for other sensors, such as pressure sensors, when their shape is different, the sensor end face tensioning mounting surface can be matched and tightly attached to other shaped outer sections.

[0038] The temperature sensor's outer clamping section 132 fits snugly against the hexagonal outer section 11; in other embodiments, for other sensors, such as pressure sensors, when their shape is different, the sensor's outer clamping section can match and fit snugly against other shaped outer sections.

[0039] The axial clamping section 232 of the connector rotating housing fits tightly against the rotating housing 21; the end face tensioning assembly surface 231 of the connector rotating housing fits tightly against the rear end face of the rotating housing 21.

[0040] In this embodiment, the two covers are two symmetrical half-shells along the central axis.

[0041] The usage process of this utility model is as follows:

[0042] (1) Assemble the retarder temperature sensor onto the retarder housing or water outlet pipe and fasten it with threads.

[0043] (2) Assemble the retarder wiring harness connector onto the temperature sensor, such as... Figure 2 As shown, the internal pin connector is connected to the pin of the temperature sensor, and the connector's rotating housing is rotated onto the rotating mating section of the temperature sensor.

[0044] (3) Assemble the male end of the protective cover onto the retarder temperature sensor and the retarder wiring harness connector: Align the external clamping section of the temperature sensor with the hexagonal shape of the temperature sensor, align the protective cover with the end face of the temperature sensor, align the protective cover with the end face of the connector rotating housing, and snap the male end of the protective cover onto the retarder temperature sensor and the retarder wiring harness connector. The external clamping section of the protective cover and the six sides of the hexagonal shape of the temperature sensor should fit tightly together so that there is no relative movement between the male end of the protective cover and the retarder temperature sensor. There is a small gap between the axial clamping section of the protective cover and the connector rotating housing.

[0045] (4) Assemble the female end of the protective cover onto the retarder temperature sensor and the retarder wiring harness connector: Align the outer clamping section of the protective cover with the hexagonal outer section of the temperature sensor, align the end face of the protective cover with the end face of the temperature sensor, align the cross-section of the protective cover and the rotating housing of the connector with the end face of the connector, and snap the female end of the protective cover onto the retarder temperature sensor and the retarder wiring harness connector. Ensure that the six faces of the outer clamping section of the protective cover and the hexagonal outer section of the temperature sensor are tightly fitted so that there is no relative movement between the female end of the protective cover and the retarder temperature sensor. There is a small gap between the axial clamping section of the protective cover and the rotating housing of the connector and the rotating housing of the connector. Snap the female end of the protective cover onto the retarder temperature sensor and the retarder wiring harness connector. At this point, the protective cover has fixed and locked the wiring harness connector and the temperature sensor, preventing relative movement between them.

[0046] (5) Fasten the male and female ends of the protective cover together using the male end protrusion and the female end slot, such as Figure 3 As shown, lock the retarder temperature sensor, retarder wiring harness connector, and protective cover, as shown. Figure 1 As shown, the axial positioning of the wiring harness connector, temperature sensor, and protective cover is achieved by tightening the protective cover with the end face of the temperature sensor and the rotating housing section of the connector, ensuring no relative axial movement. The circumferential fixation of the protective cover and temperature sensor is achieved by tightly fitting the protective cover with the six faces of the hexagonal outer section of the temperature sensor, preventing relative rotational movement. Therefore, during vehicle operation, the temperature sensor, wiring harness connector, protective cover, and retarder housing or water pipe maintain a fixed fit, with no relative axial or circumferential movement.

[0047] This design ensures that the wiring harness connector remains firmly fixed to the temperature sensor throughout the vehicle's operation, preventing loosening or detachment due to vehicle vibrations and ensuring the sensor remains axially securely attached, thus significantly improving the reliability of the vehicle's electrical connections. It also effectively prevents damage to the temperature sensor and wiring harness connector from impacts during retarder installation; furthermore, it effectively prevents damage to the sensor and wiring harness connector from flying stones or other objects during driving, thus reducing the retarder failure rate.

However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0049] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0050] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
