A fixing structure for a connector for a vehicle lamp

Abstract

The present invention provides a fixing structure for a connector for a vehicle lamp, comprising a base and a limiting wall. The connector is mounted within an area formed by the base and the limiting wall. The base is integrated into a lamp housing of the vehicle lamp. A printed circuit board is connected to the connector. The base is used to prevent the connector from falling off and half-locking. The base and the bottom of the connector are clearance-matched, thereby preventing the base from docking with the connector and generating pressure along the connector to the printed circuit board connected to the connector, thereby avoiding the problem of microcrystalline corrosion caused by friction between the connector and the connected printed circuit board due to vibration, which may lead to connector connection failure.

Description

Technical Field

[0001] The present invention relates to the field of mechanical connection of automobile lamps, and in particular to a fixing structure of a connector for automobile lamps. Background Art

[0002] With the continuous development of automotive lighting, the use of connectors and printed circuit boards is becoming more and more widespread. However, during transportation and assembly, connectors often become dislodged or not properly inserted. Furthermore, due to vibration, connectors and printed circuit boards (PCBs) can cause microcrystalline corrosion, which can lead to failure of the connection between the connector and the PCB, causing the lamp to malfunction and become scrapped. Therefore, solving the problem of microcrystalline corrosion caused by friction between connectors and PCBs is particularly important. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a fixing structure for a connector for a vehicle lamp, which ensures the limiting position of the connector and the printed circuit board, avoids the phenomenon that the connector is easily dislodged or not inserted properly after installation, and avoids the phenomenon of microcrystalline corrosion caused by friction between the connector and the printed circuit board due to vibration, thereby solving the problem of microcrystalline corrosion caused by friction between the connector and the printed circuit board.

[0004] The present invention provides a fixing structure for a connector for a vehicle lamp, comprising a base and a limiting wall. The connector is mounted within an area formed by the base and the limiting wall. The base is integrated into a lamp housing of the vehicle lamp. A printed circuit board is connected to the connector. The base is used to prevent the connector from falling off and half-locking. The base and the bottom of the connector are clearance-matched, thereby preventing the base from docking with the connector and generating pressure along the connector to the printed circuit board connected to the connector, thereby avoiding the problem of microcrystalline corrosion caused by friction between the connector and the connected printed circuit board due to vibration, which may lead to connector connection failure.

[0005] A further improvement is that the limiting wall is in a non-fully enclosed rectangular ring shape, and an opening structure 1 is provided on the left and right sides of the limiting wall respectively. The two opening structures 1 are used to reserve installation space to ensure the installation of the printed circuit board connected to the connector. The limiting wall ensures the limitation of the connector in the up and down directions and the left and right directions.

[0006] A further improvement is that four limiting ribs are respectively provided on the upper and lower sides of the inner side of the limiting wall, and the cross-section of the limiting rib gradually increases according to the draft angle of the limiting wall, that is, it gradually increases from the top of the limiting wall to the bottom of the limiting wall. The top of the limiting rib and the connector are in a clearance fit, and the gap between the limiting rib and the connector gradually decreases as the cross-section of the limiting rib increases from the top to the bottom. The fit between the limiting rib and the connector gradually changes from a clearance fit to an interference fit, thereby avoiding the shaking of the connector in the up and down directions and ensuring the reliability of the limit. The gap between the top of the limiting rib and the connector serves as a guide for the docking connector during installation, which is conducive to installation.

[0007] A further improvement is that the inner walls on the left and right sides of the limit wall are clearance-fitted with the connector, compensating for the problem that the printed circuit board connected to the connector is easily deformed in the length direction, resulting in installation deviation of the connector in the left and right directions and the inability to ensure the connection accuracy between the connector and the printed circuit board.

[0008] A further improvement is that a second opening structure is provided below the retaining wall to provide space for the wiring harness on the connector, ensuring installation of the wiring harness. The size and shape of the second opening structure are not limited, and the number and position of the second opening structures on the retaining wall can be adjusted accordingly based on the orientation and configuration of the connector wiring harness, and are not limited to the area below the positioning structure.

[0009] The present invention provides a beneficial effect by ensuring the proper positioning of the connector and the printed circuit board, preventing the connector from being easily dislodged or improperly inserted after installation, and preventing microcrystalline corrosion caused by friction between the connector and the printed circuit board due to vibration. This solves the problem of connector failure and lamp failure caused by these factors. The vehicle lamp connector's fixing structure is simple in design, easy to install, and reliable, significantly reducing design and production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0018] The coordinate system in the figure is the three-dimensional vehicle body coordinate system of the automotive industry, the positive direction of the X-axis is the negative direction of the vehicle's driving direction, and the positive direction of the Z-axis is the negative direction of the gravity direction. In the description of the present invention, it should be noted that the terms "top", "bottom", "inside", "outside", "left", "right", "up", "down", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the automotive industry and the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the system or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0019] like Figure 1-6 As shown, this embodiment provides a positioning structure for a connector, wherein the positioning structure includes a base 1 and a limiting wall 2 .

[0020] like Figure 2 As shown, the connector 3 is mounted within the area enclosed by the base 1 and the limiting wall 2 (the connector is a universal component and is not a limitation of this embodiment). The base 1 is integrated into the headlight housing (which does not affect this embodiment and is therefore not shown in this embodiment), but this is not a limitation of this embodiment and is used to prevent the connector 3 from being disengaged or partially locked.

[0021] The limiting wall 2 is a non-fully enclosed rectangular ring, and a total of two opening structures 5 are designed on the left and right sides of the limiting wall 2. The two opening structures 5 are to reserve installation space to ensure the installation of the printed circuit board 4 connected to the positioning structure and the connector 3. The limiting wall 2 ensures that the connector 3 is limited in the upper and lower directions of the headlight housing, i.e., the positive and negative directions of the Z axis, and the left and right directions, i.e., the positive and negative directions of the Y axis.

[0022] The inner walls on the left and right sides of the limiting wall 2 are clearance-fitted with the connector in the positive and negative directions of the Y-axis, compensating for the problem that the printed circuit board 4 connected to the connector 3 is easily deformed in the length direction, resulting in installation deviation of the connector 3 in the left and right directions, that is, the positive and negative directions of the Y-axis, and the connection accuracy of the connector 3 and the printed circuit board 4 cannot be guaranteed.

[0023] like Figure 3 As shown in FIG4 , the base 1 and the bottom of the connector 3 are clearance-fitted, which prevents the base 1 from docking with the connector 3 and generating pressure in the opposite direction of the installation of the connector 3 to the printed circuit board 4 connected to the connector 3, that is, the positive direction of the X-axis, thereby avoiding the problem of microcrystalline corrosion caused by friction between the connector 3 and the connected printed circuit board 4 due to vibration, which leads to failure of the connector connection.

[0024] Four limiting ribs 6 are designed on the upper and lower sides of the inner side of the limiting wall 2 respectively. The cross section of the limiting rib 6 gradually increases from the top of the limiting rib 6 to the bottom of the limiting rib 6 according to the draft angle of the limiting wall 2. The top of the limiting rib 6 and the connector 3 are in a clearance fit. The gap between the limiting rib 6 and the connector 3 gradually decreases as the cross section of the limiting rib 6 increases from the top to the bottom, so that the fit between the limiting rib 6 and the connector 3 gradually changes from a clearance fit to an interference fit, avoiding the shaking of the connector in the up and down directions and ensuring the reliability of the limit. The gap between the top of the limiting rib 6 and the connector 3 plays a guiding role in connecting the connector 3 during installation, which is conducive to installation.

[0025] like Figure 5 As shown, an opening structure 27 is designed below the limiting wall 2. The opening structure 27 is to leave space for the installation of the wiring harness on the connector 3 to ensure the installation of the wiring harness. The size and shape of the opening structure 27 are not limited, and the number and position of the opening structure 27 on the limiting wall 2 can be changed accordingly according to the direction and configuration of the wiring harness of the connector 3, and are not limited to the bottom of the positioning structure. The wiring harness on the connector is a universal structure and is not described in detail in this embodiment.

[0026] like Figure 6 As shown, the limiting wall 2 can be designed with opening structures 7 at the top and bottom according to the configuration of the wiring harness on the connector 3, leaving space for the installation of the wiring harness on the connector 3 to ensure the installation of the wiring harness. The size, shape and position of the opening structure 7 are not restricted and can be changed accordingly according to the configuration of the wiring harness on the connector 3.
