[0019] Please refer to Figures 1-9 The technical solutions provided by the present invention specifically include the following embodiments: Embodiment: An automotive ambient light conversion electrical connector includes a first connecting component 1, and a second connecting component 2 is provided at the rear side of the first connecting component 1; The first connecting component 1 includes a mounting frame 101. The inner wall of the mounting frame 101 is fixedly connected with a first connector housing 103. The front surface of the first connector housing 103 is fixedly connected with a conversion head 104. Protection holes 110 are formed on both the left and right sides of the front side of the conversion head 104. On both the left and right sides of the front side inside the first connector housing 103, first support plates 113 are fixedly connected. A screw rod 116 is rotatably connected to the inner wall of the first support plate 113. A thread groove 121 is formed on the surface of the screw rod 116. A moving plate 115 is arranged on the surface of the screw rod 116. An insulating plate 114 is fixedly connected to the rear side of the moving plate 115. A bearing tube 111 is rotatably connected to the inner wall of the protection hole 110. A screw hole 119 that cooperates with the thread groove 121 is formed through one side of the moving plate 115. The wall of the screw hole 119 is in threaded connection with the wall of the thread groove 121. A sliding groove 118 is formed through one side of the moving plate 115. A limiting rod 117 is slidably connected to the wall of the sliding groove 118. The outer side of the limiting rod 117 is fixedly connected to the inner side of the first support plate 113. Positioning plates 106 are fixedly connected to both the left and right sides of the first connector housing 103. The surface of the positioning plate 106 is slidably connected to the wall of the positioning groove 206. A buckle 105 is fixedly connected to the top of the first connector housing 103. A first bevel gear 112 is fixedly connected to the rear side of the bearing tube 111. A second bevel gear 120 is fixedly connected to the inner end of the screw rod 116. The first bevel gear 112 meshes with the second bevel gear 120. A limiting sleeve 107 is fixedly connected to the inner wall of the bearing tube 111. A synchronous convex block 124 is fixedly connected to the inner wall of the limiting sleeve 107. A telescopic tube 123 is fixedly connected to the inner wall of the bearing tube 111. A telescopic rod 109 is slidably connected to the inner wall of the telescopic tube 123. A second support plate 125 is fixedly connected to the rear side of the telescopic tube 123. Third support plates 122 are fixedly connected to both the top and bottom of the second support plate 125. The front side of the third support plate 122 is fixedly connected to the front side inside the first connector housing 103. A spiral groove 108 that cooperates with the synchronous convex block 124 is formed on the surface of the telescopic rod 109. The surface of the synchronous convex block 124 is slidably connected to the wall of the spiral groove 108; A positioning pin with the same inner diameter as the protection hole 110 is installed on the connector of the automotive wiring harness. When the connector of the automotive wiring harness is inserted into the adapter 104, if the connector of the automotive wiring harness does not match, the following three situations will occur. In the first situation, the positioning pin on the connector of the automotive wiring harness that matches the protection hole 110 can only push the expansion rod 109 on one side to move inward. At this time, the insulating plate 114 on the other side blocks the electrical connector 205, and the connector of the automotive wiring harness cannot touch the electrical connector 205, resulting in an open circuit in the circuit connection and having no impact on the automotive circuit. In the second situation, the connector of the automotive wiring harness is short and cannot be fully pushed into the expansion rod 109. At this time, the expansion rod 109 moves backward. Through the cooperation between the synchronizing projection 124 and the spiral groove 108, since the expansion rod 109 is pushed horizontally, the synchronizing projection 124 drives the limit sleeve 107 and the bearing tube 111 to rotate, causing the first bevel gear 112 to drive the second bevel gear 120 to rotate, thereby driving the screw 116 to rotate. With the limitation of the limiting rod 117, the two moving plates 115 drive the two insulating plates 114 to move horizontally outward synchronously. And when the connector is fully connected, the insulating plate 114 still blocks the electrical connector 205, and the connector of the automotive wiring harness cannot touch the electrical connector 205, resulting in an open circuit in the circuit connection and having no impact on the automotive circuit. In the third situation, when the automotive connector is too short, the automotive connector cannot touch the electrical connector 205, resulting in an open circuit in the circuit connection and having no impact on the automotive circuit. When encountering the correct connector, the expansion rod 109 moves backward. Through the cooperation between the synchronizing projection 124 and the spiral groove 108, since the expansion rod 109 is pushed horizontally, the synchronizing projection 124 drives the limit sleeve 107 and the bearing tube 111 to rotate, causing the first bevel gear 112 to drive the second bevel gear 120 to rotate, thereby driving the screw 116 to rotate. With the limitation of the limiting rod 117, the two moving plates 115 drive the two insulating plates 114 to move horizontally outward synchronously, so that the insulating plate 114 moves to the outermost side, without blocking the contact between the electrical connector 205 and the connector, facilitating the connection of the automotive wiring harness.

[0020] The second connecting component 2 includes a second connector housing 204. A protection frame 201 is fixedly connected inside the second connector housing 204. An electrical connector 205 is installed inside the protection frame 201. Positioning grooves 206 are formed on the left and right sides of the front side of the second connector housing 204. A buckle position 203 that cooperates with the buckle 105 is fixedly connected to the top of the second connector housing 204. The hook of the buckle 105 is clamped with the groove wall of the buckle position 203. An insulating ring 202 is fixedly connected to the rear side of the protection frame 201, and the rear side of the insulating ring 202 abuts against the rear side inside the second connector housing 204. By installing the insulating ring 202 at the rear side of the protective frame 201, the insulating ring 202 and the protective frame 201 form a protective component, and then the protective component is fixed on the electrical connector 205 to prevent fingers from touching the electrical connector 205 during assembly, which may cause the electrical connector 205 to carry static electricity. After assembly, there will be static electricity in the automotive wiring harness, resulting in the in - vehicle atmosphere lamp being unable to be used normally. Then, the buffer pad is fixed on the buffer groove 102, the adapter 104 is installed on the front side of the first connector housing 103, the first connector housing 103 is installed inside the installation frame 101. Then, align the positioning groove 206 and the positioning plate 106, and push the positioning plate 106 along the positioning groove 206 so that the hook of the buckle 105 is stuck on the groove wall of the buckling position 203, completing the assembly of the first connecting component 1 and the second connecting component 2. Then, insert the connecting head of the automotive wiring harness into the adapter 104 to complete the insertion of the automotive wiring harness plug. Then, insert the plug at the rear side of the second connector housing 204 into the wiring harness plug of the atmosphere lamp to complete the connection between the vehicle and the atmosphere lamp, enabling the in - vehicle atmosphere lamp to be used normally.

[0021] The insulating plate 114, the moving plate 115 and the first support plate 113 are made of plastic, the screw 116 and the bearing tube 111 are made of steel. The surface of the screw 116 is coated with insulating paint, and the surface of the bearing tube 111 is coated with a PVD coating. A buffer groove 102 is opened on the front side of the installation frame 101, and a buffer pad is installed in the buffer groove 102; By setting the surface of the screw 116 coated with insulating paint, it is avoided that the screw 116 conducts electricity. By setting the surface of the bearing tube 111 coated with a PVD coating, the friction coefficient on the surface of the bearing tube 111 is reduced, making the bearing tube 111 not easily worn and improving the service life of the bearing tube 111.

[0022] The first bevel gear 112 and the second bevel gear 120 are both made of steel, and the surfaces of the first bevel gear 112 and the second bevel gear 120 are both coated with insulating paint; By setting the surfaces of the first bevel gear 112 and the second bevel gear 120 both coated with insulating paint, it is avoided that the first bevel gear 112 and the second bevel gear 120 conduct electricity.

[0023] The limiting sleeve 107, the telescopic rod 109 and the synchronous convex block 124 are all made of iron, and the surfaces of the limiting sleeve 107, the telescopic rod 109 and the synchronous convex block 124 are all coated with a PVD coating. The telescopic tube 123, the second support plate 125 and the third support plate 122 are all made of plastic; The surfaces of the provided limit sleeve 107, telescopic rod 109, and synchronous convex block 124 are all coated with a PVD coating, reducing the friction coefficient on the surfaces of the limit sleeve 107, telescopic rod 109, and synchronous convex block 124, making the limit sleeve 107, telescopic rod 109, and synchronous convex block 124 not easily worn, and improving the service life of the limit sleeve 107, telescopic rod 109, and synchronous convex block 124; The PVD coating is a technology where, under vacuum conditions, the plating target material is heated and evaporated, causing a large number of atoms and molecules to vaporize and leave the liquid plating material or the surface of the solid plating material, and ultimately depositing on the surface of the substrate. During this entire process, the gaseous atoms and molecules will undergo very few collisions in the vacuum and directly migrate to the substrate and deposit on the surface of the substrate to form a thin film. The evaporation methods include resistance heating, high-frequency induction heating, electron beam, laser beam, ion beam high-energy bombardment of the plating material, etc. After coating, the surface of the material has a low friction coefficient and can effectively reduce the wear caused by friction of the material; Insulating paint, also known as insulating coating, is a type of paint with excellent electrical insulation properties. It has good electrochemical properties, thermal properties, mechanical properties, and chemical properties. It is mostly varnish, and there are also colored paints. Insulating paint is a special type of paint among paints. Insulating paint is based on high molecular polymers and is an important insulating material that can cure into an insulating film or an insulating whole under certain conditions.

[0024] When assembling a car ambient light conversion electrical connector in this solution, first install the insulating ring 202 at the rear side of the protective frame 201, so that the insulating ring 202 and the protective frame 201 form a protective component. Then fix the protective component on the electrical connector 205 to prevent fingers from touching the electrical connector 205 during assembly, which may cause the electrical connector 205 to carry static electricity, resulting in static electricity existing in the car wiring harness after assembly and causing the ambient light in the car to be unable to be used normally. Then fix the buffer pad on the buffer groove 102, install the conversion head 104 on the front side of the first connector housing 103, install the first connector housing 103 inside the installation frame 101. Then align the positioning groove 206 and the positioning plate 106, and push the positioning plate 106 along the positioning groove 206 so that the hook of the buckle 105 is stuck on the groove wall of the buckle position 203 to complete the assembly of the first connection component 1 and the second connection component 2. Then insert the connection head of the car wiring harness into the conversion head 104 to complete the insertion of the car wiring harness plug. Then insert the plug at the rear side of the second connector housing 204 into the wiring harness plug of the ambient light to complete the connection between the car and the ambient light, enabling the ambient light in the car to be used normally; A positioning pin with the same inner diameter as the protective hole 110 is installed on the connector of the automotive wiring harness. When the connector of the automotive wiring harness is inserted into the adapter 104, if the connector of the automotive wiring harness does not match, the following three situations will occur. In the first situation, the positioning pin on the connector of the automotive wiring harness that matches the protective hole 110 can only push the expansion rod 109 on one side to move inward. At this time, the insulating plate 114 on the other side blocks the electrical connector 205, and the connector of the automotive wiring harness cannot touch the electrical connector 205, resulting in an open circuit in the circuit connection and having no impact on the automotive circuit. In the second situation, the connector of the automotive wiring harness is short and cannot be fully pushed into the expansion rod 109. At this time, the expansion rod 109 moves backward. Through the cooperation between the synchronizing convex block 124 and the spiral groove 108, since the expansion rod 109 is horizontally pushed, the synchronizing convex block 124 drives the limit sleeve 107 and the bearing tube 111 to rotate, causing the first bevel gear 112 to drive the second bevel gear 120 to rotate, thereby driving the screw 116 to rotate. With the limitation of the limiting rod 117, the two moving plates 115 drive the two insulating plates 114 to move horizontally outward synchronously. And when the connector is fully connected, the insulating plate 114 still blocks the electrical connector 205, and the connector of the automotive wiring harness cannot touch the electrical connector 205, resulting in an open circuit in the circuit connection and having no impact on the automotive circuit. In the third situation, when the automotive connector is too short, the automotive connector cannot touch the electrical connector 205, resulting in an open circuit in the circuit connection and having no impact on the automotive circuit; When encountering the correct connector, the expansion rod 109 moves backward. Through the cooperation between the synchronizing convex block 124 and the spiral groove 108, since the expansion rod 109 is horizontally pushed, the synchronizing convex block 124 drives the limit sleeve 107 and the bearing tube 111 to rotate, causing the first bevel gear 112 to drive the second bevel gear 120 to rotate, thereby driving the screw 116 to rotate. With the limitation of the limiting rod 117, the two moving plates 115 drive the two insulating plates 114 to move horizontally outward synchronously, so that the insulating plate 114 moves to the outermost side, without blocking the contact between the electrical connector 205 and the connector, facilitating the connection of the automotive wiring harness.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
