Description

Technical Field

[0001] The utility model belongs to the field of vehicle signal cable connection, in particular to an anti-vibration connection component. Background Art

[0002] The control cable of a vehicle is the nerve of the vehicle's movement, but the inside of the vehicle is a working environment with various complex conditions such as vibration, friction, ozone, oil, high heat, cold and electromagnetic radiation. The cables of the vehicle are required to have various functions such as heat resistance, cold resistance, wear resistance, oil resistance and anti-interference to ensure the driving safety of the vehicle. Nowadays, the cables of vehicles have overcome many technical difficulties due to the rapid development of materials science, but many people have ignored the way of installing and fixing the connector. At present, the connector is directly connected to the mounting panel through fasteners. This connection method is easily affected by the installation environment and causes the connection to fail; for example, when the connector is close to the engine, the huge vibration generated by the engine will seriously affect the transmission of the signal, causing the signal transmission to fail or be interrupted. In terms of car driving, this is related to whether the vehicle stability control system, active body posture control system, cruise control system, anti-collision warning system, driver intelligent support system, steering system, suspension system, wheel hub motor, braking system, intelligent auxiliary motor, electronic vacuum pump, ABS sensor, vehicle speed sensor and other signal control components can operate normally. These control systems are extremely important, which may affect the driving experience at the least and cause the safety of passengers' lives at the worst.

[0004] 1. Connectors connected directly through fasteners are easily affected by the installation environment and cause connection failure;

[0005] 2. After the fasteners are installed, pressing the elastic parts vigorously may cause the elastic parts to age;

[0006] 3. The fasteners installed on the mounting plate are not shockproof, waterproof, and dustproof. Utility Model Content

[0037] Please refer to Figure 1-8 ,

[0038] like Figure 1 As shown, the utility model provides an anti-vibration connection component, including a connector 2, a fastener 3, an elastic member 4, and a support member 5 arranged on a mounting plate 1, characterized in that: the mounting plate 1 is provided with a mounting hole 11, the elastic member 4 can be inserted into the mounting hole 11, the elastic member 4 is provided with a hole 41, the hole 41 can be inserted with the support member 5, and the connector 2 is arranged in the mounting hole 11 through the elastic member 4 and the support member 5. By arranging the elastic member 4 in the mounting hole 11, the forces in the Y-axis and Z-axis directions generated by the connector 2 during vibration can be reduced, and at the same time, the support member 5 is inserted inside the elastic member 4 to provide support for the fastener 3, so as to prevent the elastic member 4 from being damaged by rubber aging under long-term and strong pressure, thereby extending the service life of the connector 2.

[0039] like Figure 2 As shown, a radial annular protruding flange 42 is provided at the top of the elastic member 4. When the fastener 3 is pressed downward, the flange 42 at the top of the elastic member 4 will deform axially inward toward the mounting hole 11, so that the flange 42 fits more closely with the mounting plate 1, thereby achieving the first level of dustproof and waterproof effect.

[0040] like Figure 2 , Figure 3 As shown, the connector 2 is provided with a second hole 21, and the distance a between the outer ring surface 211 of the second hole 21 and the thickness of the mounting plate 1 is smaller than the distance b below the flange 42 of the elastic member 4. When the flange 42 is mounted and fitted on the mounting plate 1, the length b below the flange 42 of the elastic member 4 is larger than the distance a between the outer ring surface 211 of the second hole 21 and the thickness a of the mounting plate 1, and when the fastener 3 is pressed downward, the elastic member 4 will be slightly deformed to achieve the second layer of dustproof and waterproof effect.

[0041] The reason for the two-layer dustproof and waterproof design in this embodiment is that there is a support member 5 inside the elastic member 4, and the waterproof level cannot reach the waterproof effect of dozens or even hundreds of atmospheres, but ordinary people do not need to drive vehicles diving in daily life. Although the elastic member 4 and the support member 5 are used together to lose the redundant daily waterproof needs, the stability of the connector 2 is greatly enhanced, and the two-layer waterproof structure can meet the driving needs in most conditions.

[0042] like Figure 4 As shown, the axial height c of the elastic member 4 is greater than the axial height d of the support member 5. When the axial height c of the elastic member 4 is greater than the axial height d of the support member 5, the elastic member 4 has a margin for pressing downwards, and if c≤d, the dustproof and waterproof performance will be greatly reduced or the dustproof and waterproof effects cannot be achieved.

[0043] like Figure 5 As shown, the fastener 3 is provided with a fastening end face 321, and the fastening end face 321 can simultaneously press the elastic member 4 and the support member 5. The fastening end face 321 of the fastener 3 can simultaneously press the elastic member 4 and the support member 5, and the support member 5 provides a hard limit when the fastener 3 is pressed downward, so as to prevent the elastic member 4 from being rapidly aged due to excessive pressure for a long time, and at the same time, the elastic member 4 acts as an elastic gasket, which can be used to prevent the fastener 3 from loosening, thereby avoiding the inconvenience of applying screw glue, which is easy to age and inconvenient to disassemble.

[0044] like Figure 6 As shown, the connector 2 has an elastic ring 6 near the outer edge of the fitting surface 22. The elastic ring 6 on the fitting surface 22 of the connector 2 can achieve the third layer of dustproof and waterproof. The elastic ring 6 can resist the mounting plate 1, so that the mounting plate 1 is subjected to an inward tightening force and an outward counter-thrust force at the same time.

[0045] like Figure 1 , Figure 6 As shown, the height of the elastic ring 6 is higher than all features other than the joint on the fitting surface 22 of the connector 2, and the connector 2 can only contact the mounting plate 1 through the elastic ring 6. When the connector 2 can only contact the mounting plate 1 through the elastic ring 6, the entire connector 2 is fixed to the mounting plate 1 through the elastic component, and at this time, the force from the X-axis direction received by the connector 2 is filtered through the elastic component.

[0046] By using the elastic member 4 and the elastic ring 6 in combination, the vibration force from the three directions of the X, Y and Z axes is mitigated, thereby enhancing the connection stability of the cable of the connector 2.

[0047] like Figure 6 As shown, the elastic ring 6 is made of elastic material on the outside and inelastic material on the inside. When the operator uses the fastener to fix the connector, when it is fixed to a certain degree, it suddenly cannot be fixed downwards. This is a warning method of the elastic ring 6. At this time, the operator should loosen the fastener upwards by 0.5mm-1mm to avoid crushing the elastic ring 6 and extend the service life of the elastic ring 6.

[0048] like Figure 7As shown, a column 23 is provided behind the corresponding position of the second hole 21 of the connector 2, and the depth of the second hole 21 can extend into the column 23, increasing the contact surface 231 in the second hole 21. The depth of the second hole 21 can extend into the column 23, which is a method of achieving connection stability by increasing the contact area.

[0049] like Figure 8 As shown, the mounting plate 1 includes a port hole 12, and the connector 2 includes a connection port 24, which can extend from the port hole 12. The connection port 24 extends from the port hole 12 to facilitate male and female plug-in connection.
