Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted power socket structures, in particular to a vehicle-mounted power socket with an anti-misinsertion structure. Background Art

[0002] The anti-misinsertion car power socket is a specially designed car power socket that is designed to prevent users from inserting the power plug into the socket incorrectly, thereby avoiding possible electrical short circuits, equipment damage or other safety issues. This design is crucial to improving safety during use, especially when facing electrical devices with high current or requiring precise control.

[0003] Common ways to prevent mis-insertion are as follows:

[0004] 1. Unique plug and socket design:

[0005] Anti-mating sockets use an asymmetrical design or unique shape to ensure that a plug can only be inserted when it is in the correct orientation. This physical fit prevents incorrect insertion.

[0006] 2. Mechanical positioning and locking:

[0007] To further increase safety, these sockets may contain additional locking mechanisms that activate only when the plug is fully and correctly inserted.

[0008] 3. Electronic testing:

[0009] In some advanced designs, the socket may also include electronic detection capabilities that can identify whether the plug is correct and decide whether to allow current to flow accordingly.

[0010] 4. Coding and marking:

[0011] Anti-misplugging car power sockets may also use intuitive methods such as color coding and shape marking to help users identify and operate correctly.

[0012] The application number is 201220626934.2. A vehicle-mounted power socket and a vehicle. The vehicle-mounted power socket includes a shell and a retaining frame arranged in the shell. The shell is provided with a shell plug hole. A retaining frame plug hole is provided at a position corresponding to the shell plug hole on the retaining frame. A slider is provided between the retaining frame and the shell. The slider has two working positions: covering the retaining frame plug hole and exposing the retaining frame plug hole.

[0013] However, during the use of the above-mentioned sockets, errors still occur because the sockets are all square. Utility Model Content

[0014] In view of the above problems, the utility model provides a vehicle-mounted power socket with an anti-misinsertion structure. The shape of the socket is modified to be different. When the plug and the socket do not correspond one to one, the plug cannot be inserted into the socket. At the same time, a protective mechanism is provided under the socket to avoid misinsertion and leakage, thereby providing leakage protection.

[0015] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0016] A vehicle-mounted power socket with an anti-misinsertion structure, comprising:

[0017] Body, panel and wiring harness assembly;

[0018] The body is T-shaped, and includes a connecting plate and a mounting seat. The connecting plate is horizontally arranged, and the mounting seat is vertically arranged. Sockets A, B and C are respectively arranged in the mounting seat.

[0019] The panel is installed at the opening of the mounting seat, and a first jack and a second jack are provided on the panel. The second jack is symmetrically arranged in two groups, and the first jack and the second jack correspond to the socket A, the socket B and the socket C respectively.

[0020] The wiring harness assembly is extended outward from the body, and the wiring harness assembly is connected to two non-grounded sockets among the socket A, the socket B and the socket C.

[0021] As an improvement, a guide block and a clamping block are provided on the side wall of the mounting seat;

[0022] The guide block is in the shape of an elongated strip and is arranged on the side wall of the mounting seat;

[0023] The clamping block is arranged at an opening on the side wall of the mounting seat, and the clamping block is arranged to protrude from the side wall of the mounting seat in a pointed angle.

[0024] As an improvement, a positive pressure plate is arranged in the mounting seat, and the positive pressure plate is connected to a group of sockets used as positive sockets among the socket A, socket B or socket C, and the positive pressure plate is connected to the wiring harness assembly.

[0025] As an improvement, a grounding pressure plate is arranged in the mounting seat, and the grounding pressure plate is connected to a group of sockets among the socket A, the socket B or the socket C used as grounding sockets.

[0026] As an improvement, a protective mechanism is provided below the first plug hole and the second plug hole, and the protective mechanism seals the first plug hole and the second plug hole.

[0050] Embodiment 1:

[0051] like Figures 1 to 5 As shown, a vehicle-mounted power socket with an anti-misinsertion structure comprises:

[0052] Main body 1, panel 2 and wiring harness assembly 3;

[0053] The body 1 is T-shaped, and includes a connecting plate 11 and a mounting seat 12. The connecting plate 11 is horizontally arranged, and the mounting seat 12 is vertically arranged. The mounting seat 12 is provided with a socket A121, a socket B122, and a socket C123 respectively.

[0054] The panel 2 is installed at the opening of the mounting base 12, and a first plug hole 21 and a second plug hole 22 are provided on the panel 2. The second plug holes 22 are symmetrically arranged in two groups, and the first plug holes 21 and the second plug holes 22 correspond to the socket A121, the socket B122 and the socket C123 respectively. The first plug hole 21 is arranged in a keyhole shape, and the first plug hole 21 and the second plug hole 22 are arranged in a triangular distribution;

[0055] The wiring harness assembly 3 extends outward from the body 1 and connects two non-grounded sockets among the socket A121, the socket B122 and the socket C123.

[0056] In order to facilitate the installation of the mounting seat 12, a guide block 124 and a clamping block 125 are provided on the side wall of the mounting seat 12;

[0057] The guide block 124 is arranged on the side wall of the mounting seat 12 in a long strip shape. When the socket is installed on the vehicle body, the guide block 124 cooperates with the card slot on the vehicle body to install the socket and avoid misalignment of the socket.

[0058] The card block 125 is arranged at the opening on the side wall of the mounting seat 12, and the card block 125 protrudes from the side wall of the mounting seat 12 in a pointed angle. Specifically, the card block 125 is arranged in a triangular structure. When the socket is installed, the card block 125 will be squeezed into the opening on the side wall of the mounting seat 12. When the mobile socket is installed in place, the card block 124 will pop out and cooperate with the concave and convex card slot on the vehicle body to fix the mounting seat 12.

[0059] In addition, a positive pressure plate 4 is arranged in the mounting seat 12 , and the positive pressure plate 4 is connected to a group of sockets used as positive sockets among the socket A121 , the socket B122 or the socket C123 , and the positive pressure plate 4 is connected to the wiring harness assembly 3 .

[0060] The socket of the utility model is a three-hole socket, one of the sockets A121, B122 or C123 is a grounding socket, and the other two are positive and negative sockets. Therefore, the positive pressure plate 4 is connected to one of the three groups of sockets as the positive socket, and the positive pressure plate 4 is in the vehicle-mounted socket, and the positive pressure plate plays the role of connecting the power supply to transmit the power supply to the device or device.

[0061] In addition, a grounding pressure plate 5 is provided in the mounting base 12, and the grounding pressure plate 5 is connected to a group of sockets used as grounding sockets among the socket A121, the socket B122 or the socket C123. The grounding pressure plate is used to connect the grounding wire to ensure that the equipment has good grounding when working, so as to prevent safety problems such as leakage of electrical equipment.

[0062] As a preferred embodiment, the wiring harness assembly 3 includes a wiring harness 31, a sheath 32 and a buckle 33;

[0063] The wire harness 31 is connected to the sheath 32 , and a buckle 33 is provided on the sheath 32 to fix the sheath 32 .

[0064] It should be noted that the wiring harness assembly 3 is used to connect the socket and the vehicle power supply. The sheath 32 in the wiring harness assembly 3 is fixed to the vehicle body by a buckle 33, which can prevent the sheath 32 from shaking and causing the sheath 32 to fall off from the connecting wire.

[0065] Embodiment 2:

[0066] With reference to Example 1, the difference between Example 2 of the utility model and Example 1 is described as follows:

[0067] like Figures 6 to 8 As shown, a protective mechanism 6 is disposed below the first plug hole 21 and the second plug hole 22 , and the protective mechanism 6 seals the first plug hole 21 and the second plug hole 22 .

[0068] Specifically, the protection mechanism 6 includes a slider 61 and a spring 62;

[0069] The slider 61 is slidably disposed below the first plug hole 21 and the second plug hole 22, respectively, and the upper end surface of the slider 61 is inclined;

[0070] The spring 62 is installed between the slider 61 and the body 1 in a resisting manner.

[0071] Furthermore, a limiting hole 611 is provided on the slider 61 . When the slider 61 slides to open the first socket 21 and the second socket 22 , the plug inserted into the first socket 21 is inserted into the limiting hole 611 to limit the slider 61 .

[0072] It should be noted that in the initial state, the slider 61 blocks and seals the first and second sockets 21, 22, which can achieve the purpose of dust and water resistance. When the plug is inserted into the first and second sockets 21, 22, the plug and the slider 61 are pressed together to squeeze the spring 62 on the slider 61, thereby pushing the slider 61 to move, so that the first and second sockets 21, 22 are opened. When the plug is inserted into the first and second sockets 21, 22, the spring 62 on the slider 61 is pressed together to squeeze the spring 62 on the slider 61, thereby pushing the slider 61 to move, so that the first and second sockets 21, 22 are opened. The insert in the hole 21 will intersect and cooperate with the limiting hole 611, thereby limiting the slider 61, changing the original method of limiting by the mutual interference between the slope end of the slider and the plug insert. Since the thickness of the slope end of the slider is relatively thin and the thickness of the plug insert is also relatively small, the mutual interference between the slope end of the slider and the plug insert can easily cause wear of the slope end of the slider. However, limiting by the mutual interference between the limiting hole 611 and the insert can greatly reduce the wear of the slope end of the slider and extend the service life of the slider.

[0073] 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.
