[0040] Embodiment 1:

[0041] like Figures 1 to 6 As shown, a dual-hole vehicle power socket includes:

[0042] Housing 1, terminal 2, panel 3 and cover 4;

[0043] The housing 1 is gradually contracted from the panel 3 toward the terminal 2, and elastically compressed blocks 11 are provided on both side walls of the housing 1, and the blocks 11 protrude from the side walls of the housing 1;

[0044] The two groups of terminals 2 are symmetrically installed in the housing 1. The terminals 2 are arranged in a spring sheet structure. Specifically, the terminals 2 are arranged in an arrow shape. The terminals 2 are arranged by bending a conductive metal sheet.

[0045] The panel 3 is disposed on the housing 1 , and two groups of jacks 31 are provided on the panel 3 , and the jacks 31 are disposed one-to-one correspondingly with the terminals 2 ;

[0046] The cover 4 is rotatably mounted on one end of the housing 1 on which the panel 3 is provided through a pin 5. The cover 4 and the housing 1 are locked and matched through a buckle group 6. The buckle group 6 includes a locking tongue 61 and a buckle block 62. The locking tongue 61 extends outward from the cover 4. The locking tongue 61 is arranged in a broken line shape. The buckle block 62 extends outward from the housing 1. A protrusion 621 is provided at the end of the buckle block 62 and the locking tongue 61 for locking.

[0047] Among them, the card block 11 is integrally injection-molded with the shell 1, and the elastically compressed end of the card block 11 is stepped. The stepped end is used to form a limit block after the shell 1 is installed on the vehicle body to prevent the shell 1 from withdrawing backward from the vehicle body, and the card block 11 is a group of elastic extrusion settings. When the shell 1 is inserted into the vehicle body, the card block 11 will be compressed. Once the shell 1 is inserted into place, the card block 11 will open and clamp the mounting plate of the vehicle body to prevent the shell 1 from falling off.

[0048] It should be noted that the housing 1 is installed on the car, and the panel 3 is set outward. The functional end jack 31 is located on the panel 3 and connected to the terminal 2. When in use, the plug is inserted through the jack 31 to form contact with the terminal 2. When the plug is inserted, the spring sheet structure of the terminal 2 will be squeezed by the plug to form a close contact with the plug. The two groups of terminals 2 are respectively set as positive and negative poles, and the terminal is located at the end inside the housing 1, and is connected to the vehicle power cord through a connector and an inverter.

[0049] It is further explained that when the socket is waterproof and dustproof, a flip-up cover 4 is provided on the panel 3, and the cover 4 is used to protect the socket 31. When the cover 4 protects the panel 3, the lock of the cover is achieved through the concave-convex fit between the lock tongue 61 and the buckle block 62, wherein the concave-convex fit ends of the lock tongue 61 and the buckle block 62 are locked by respectively adopting the method of slope and circular arc convex fit. When unlocking, the slope of the lock tongue 61 is just squeezed by the circular arc convex point and moves inward, smoothly releasing the concave-convex interference fit between the lock tongue 61 and the buckle block 62.

[0050] Embodiment 2:

[0051] With reference to Example 1, the difference between Example 2 of the utility model and Example 1 is described as follows:

[0052] like Figure 2As shown, a support plate 12 is extended outwardly from the housing 1, and the support plate 12 is located below the pin 5, and the support plate 12 supports the flipped cover 4. Moreover, the support plate 12 is arranged in an arc shape, and the support plate 12 and the outer end surface of the cover 4 are arranged in a contour.

[0053] Since the existing shell 1 and cover 5 are mostly made of plastic parts and are connected by a pin 5, the cover 4 can easily fall off the shell 1 when the cover 5 is turned over, which greatly reduces the service life of the cover 4 and also reduces the safety protection capability.

[0054] Embodiment 4:

[0055] With reference to Example 1, the difference between Example 4 of the utility model and Example 1 is described as follows:

[0056] like Figure 3 , Figure 6 As shown, the outer ring of the locking tongue 61 on the cover 4 is provided with a blocking ring 41, and the blocking ring 41 is arranged around the panel 3. Two groups of sealing plugs 42 are arranged on the cover 4 at positions directly opposite to the insertion hole 31.

[0057] It should be noted that in order to enhance the protective capability of the cover 4 on the socket 31, when the cover 4 covers the socket 31, the blocking ring 41 will be wrapped around the outside of the panel 3, thereby providing a second waterproof and dustproof effect. The sealing plug 42 is made of an insulating and elastically stretchable insulating rubber material. When the cover 4 covers the socket 31, the sealing plug 42 will be inserted into the socket 31 to block and seal the socket 31. The sealing plug 42 is slightly larger than the socket 31. Therefore, after the sealing plug 42 is inserted into the socket 31, it will completely fill the socket 31, thereby providing a second waterproof and dustproof effect.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
