Description

Technical Field

[0001] This utility model relates to the field of automotive oxygen sensor technology, and in particular to a ceramic fastener for connecting automotive oxygen sensor wiring harnesses. Background Technology

[0002] Ceramic fasteners for automotive oxygen sensor wiring harnesses are typically used to securely fix the oxygen sensor wiring harness in a suitable position, ensuring that the sensor can function properly and that the wiring harness is not damaged by vibration or environmental factors. Ceramic material has good insulation properties, which can effectively prevent the oxygen sensor wiring harness from contacting the vehicle's metal parts or other objects that may cause electrical short circuits. The ceramic material can firmly connect the wiring harness and the sensor together, maintaining a good fixing effect even in high temperature and vibration environments.

[0003] Cars are frequently subjected to vibrations, impacts, and other external physical shocks during driving. Ceramic fasteners are relatively fragile, and when repeatedly subjected to external forces, their surfaces will show varying degrees of damage, which will cause the wiring harness and fasteners to loosen, affecting the normal operation of the car oxygen sensor. Therefore, a ceramic fastener for connecting car oxygen sensor wiring harnesses is designed. Utility Model Content

The wrapping sleeve and the protective sleeve are movable at one end of the ceramic fastener body. The bottom surfaces of multiple second magnet blocks gradually approach the surfaces of multiple first magnet blocks. Due to their magnetic connection, the first and second magnet blocks are attracted to each other, allowing the auxiliary sleeve and the wrapping sleeve to be installed. The protective sleeve then covers the outer surface of the ceramic fastener body. The protective sleeve is made of glass fiber composite material, which is lightweight and has resistance to external forces, enhancing the resistance of the ceramic fastener body to external forces. The wear-resistant layer is made of aluminum nitride material, which has thermal conductivity and wear resistance, extending the service life of the ceramic fastener body.

The anti-pressure pad is made of aluminum alloy, which provides hardness, and the anti-slip texture increases the friction between the anti-pressure pad and the mounting surface, thus improving the stability of the ceramic fastener body. When the protective sleeve is placed on the outer surface of the ceramic fastener body, the two arc-shaped blocks are aligned with the arc-shaped groove in sequence to quickly achieve the fitting of the protective sleeve and the ceramic fastener body, accelerating the splicing speed.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a ceramic fastener for connecting automotive oxygen sensor wiring harnesses:

[0022] Example 1:

[0023] like Figure 1-3 As shown, a ceramic fastener for connecting an automotive oxygen sensor wiring harness includes a ceramic fastener body 1 and multiple slots 2. The multiple slots 2 are respectively opened at the top of the ceramic fastener body 1. An auxiliary sleeve 3 is fixedly sleeved at one end of the ceramic fastener body 1. A protruding plate 4 is fixedly installed on both sides of the auxiliary sleeve 3. Multiple first magnet blocks 5 are provided on the top of the auxiliary sleeve 3. A wrapping sleeve 7 is sleeved at one end of the ceramic fastener body 1. Multiple second magnet blocks 9 are provided at the bottom of the wrapping sleeve 7. Due to the magnetic connection between the two, after the first magnet blocks 5 and the second magnet blocks 9 are attracted, the auxiliary sleeve 3 and the wrapping sleeve 7 can be installed. The protective sleeve 12 can then cover the outer surface of the ceramic fastener body 1. The protective sleeve 12 is made of glass fiber composite material, which is lightweight and has external force resistance, enhancing the external force resistance of the ceramic fastener body 1. The wear-resistant layer 15 is made of aluminum nitride material, which has thermal conductivity and wear resistance, extending the service life of the ceramic fastener body 1.

[0024] Example 2:

[0025] Based on Example 1, such as Figure 1 and Figure 4As shown, the top of each of the two protruding plates 4 is provided with an arc-shaped groove 6, and arc-shaped blocks 8 are fixedly installed on both sides of the cover 7. A protective sleeve 12 is fixedly installed on the top of the cover 7. The inner surface of the protective sleeve 12 is coated with a wear-resistant layer 15. By setting the protruding plates 4, arc-shaped grooves 6, arc-shaped blocks 8 and pressure-resistant pads 10, the slot 2 is connected to the automotive oxygen sensor wiring harness. The pressure-resistant pad 10 is made of aluminum alloy material, which has hardness, and the anti-slip texture 11 can increase the friction between the pressure-resistant pad 10 and the mounting surface, thereby improving the firmness of the ceramic fastener body 1. When the protective sleeve 12 is put on the outer surface of the ceramic fastener body 1, the two arc-shaped blocks 8 are aligned with the arc-shaped grooves 6 in sequence, so that the protective sleeve 12 and the ceramic fastener body 1 can be put on quickly.

[0026] Working Principle: The ceramic fastener for automotive oxygen sensor wiring harness connections is typically used to stably fix the oxygen sensor wiring harness in a suitable position, ensuring the sensor functions normally and preventing damage to the wiring harness due to vibration and environmental factors. Ceramic material has excellent insulation properties, effectively preventing the oxygen sensor wiring harness from contacting vehicle metal parts or other objects that could cause electrical short circuits. The ceramic material can firmly connect the wiring harness and sensor together, maintaining good fixation even in high-temperature and vibration environments. During vehicle operation, cars frequently encounter vibrations, impacts, and other external physical shocks. Ceramic fasteners are relatively fragile; repeated external forces can cause varying degrees of surface damage, leading to loosening of the wiring harness and fastener, affecting the normal operation of the automotive oxygen sensor. Therefore, a ceramic fastener for automotive oxygen sensor wiring harness connections is designed. The sheath 7 and protective sleeve 12 are movable at one end of the ceramic fastener body 1, and the bottom surface of multiple second magnet blocks 9... As the first magnet 5 and the second magnet 9 gradually approach each other, they become magnetically connected. After the first magnet 5 and the second magnet 9 are attracted, the auxiliary sleeve 3 and the wrapping sleeve 7 can be installed. The protective sleeve 12 can then cover the outer surface of the ceramic fastener body 1. The protective sleeve 12 is made of glass fiber composite material, which is lightweight and has resistance to external forces, thus enhancing the resistance to external forces of the ceramic fastener body 1. The wear-resistant layer 15 is made of aluminum nitride material, which has thermal conductivity and wear resistance, thus extending the service life of the ceramic fastener body 1. The slot 2 is connected to the automotive oxygen sensor wiring harness. The pressure pad 10 is made of aluminum alloy material, which has hardness, and the anti-slip texture 11 increases the friction between the pressure pad 10 and the mounting surface, thus improving the firmness of the ceramic fastener body 1 installation. When the protective sleeve 12 is put on the outer surface of the ceramic fastener body 1, the two arc-shaped blocks 8 are aligned with the arc-shaped groove 6 in sequence, so that the protective sleeve 12 and the ceramic fastener body 1 can be put on quickly, thus speeding up the splicing speed.
