Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a dustproof structure for electric connectors. Background Art

[0002] A USB connector is an interface connector used to connect external devices to a computer. It follows the Universal Serial Bus (USB) standard for data transmission and power supply. USB connectors usually have a convenient plug-in design and support hot-plugging. They can connect various external devices such as printers, keyboards, mice, cameras, speakers, mobile storage devices, etc. to exchange data and control devices with computers.

[0003] The plug part of the existing USB connector is usually provided with a dust cap to play a protective and dust-proof role, but the existing dust cap is separately provided with the USB connector body, so that the dust cap will be completely separated from the USB connector body during use, which may easily lead to the loss of the dust cap, and thus the protection and dust-proof role cannot be played. Therefore, corresponding improvements are needed according to the above problems. Utility Model Content

[0006] Preferably, a toggle block is installed on the outer side of the dust cover, and a hand-holding groove is provided at the top and bottom ends of the toggle block.

[0007] Preferably, the size of the outer frame of the limiting block is matched with the size of the inner frame of the limiting groove.

[0008] Preferably, the two groups of iron rods are equal in size, and one end of the two groups of iron rods is adsorbed and fixed to the corresponding side of the corresponding magnet block respectively.

[0009] Preferably, the two groups of magnet blocks are of equal size, and the sizes of the vertical cross-sections of the two groups of magnet blocks are respectively adapted to the sizes of the top surfaces of the corresponding iron plates.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The arrangement of components such as limit grooves, iron plates, mounting blocks, iron rods, mounting sleeves, telescopic ropes, magnet blocks, dust covers and limit blocks can effectively solve the problem that the existing dust cap is separated from the USB connector body, so that the dust cap will be completely separated from the USB connector body during use, which may easily lead to the dust cap being lost and thus failing to provide protection and dustproofing.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figures 1 to 3The utility model provides a technical solution: a dustproof structure for an electrical connector, comprising a USB connector 1, a limiting groove 11 is provided at the middle position of the top of the USB connector 1, and iron plates 12 are installed at the middle position of the top of both sides of the USB connector 1, mounting blocks 13 are installed at the middle position of both sides of the USB connector 1, and iron rods 14 are installed at one side of two groups of mounting blocks 13, the two groups of iron rods 14 are equal in size, and one end of the two groups of iron rods 14 is respectively adsorbed and fixed to the corresponding side of the corresponding magnet block 2, mounting sleeves 15 are installed at the positions of the corresponding mounting blocks 13 on both sides of the USB connector 1, and retractable ropes 16 are installed at one end of the two groups of mounting sleeves 15.

[0018] The other ends of the two sets of telescopic ropes 16 are both installed with magnet blocks 2, and one side of the two sets of magnet blocks 2 is respectively installed with the corresponding side of the dust cover 21, the two sets of magnet blocks 2 are equal in size, and the vertical cross-sectional sizes of the two sets of magnet blocks 2 are respectively adapted to the top surface size of the corresponding iron plate 12, and the inner side of the dust cover 21 is installed with a limit block 22. In the initial state (i.e. Figure 1 In the state shown), the limit block 22 will be located inside the plug of the USB connector 1 for corresponding storage, the outer frame size of the limit block 22 is adapted to the inner frame size of the limit slot 11, a toggle block 23 is installed on the outer side of the dust cover 21, and a hand-holding slot 24 is provided at the top and bottom of the toggle block 23.

[0019] In the initial state (i.e. Figure 1 In the state shown), the dust cover 21 will be located and fixed at the end of the plug part of the USB connector 1, so that under the setting of the dust cover 21, the plug part of the USB connector 1 can be protected and dustproofed accordingly.

[0020] When the user needs to use the USB connector 1, the user can move the dust cover 21 accordingly through the two groups of hand-held slots 24, so that it can be separated from the plug part of the USB connector 1, so that one end of the two groups of iron rods 14 is separated from the corresponding side of the corresponding magnet block 2, so that the two groups of telescopic ropes 16 can be retracted accordingly. At this time, the user can place the dust cover 21 on the top of the USB connector 1 through the toggle block 23 and the hand-held slot 24, so that the limit block 22 will be located inside the limit slot 11 for corresponding limit changes. The bottom surfaces of the two groups of magnet blocks 2 will be adsorbed and fixed with the top surfaces of the corresponding iron plates 12. During this process, the two groups of telescopic ropes 16 will be telescoped accordingly, so that the dust cover 21 can be fixed at the middle position of the top of the USB connector 1, so that the USB connector 1 can be normally plugged and electrically connected. When the USB connector 1 is used up, the above operation can be performed in reverse order to place the dust cover 21 at the initial position and fix it accordingly, and at the same time, the plug part of the USB connector 1 can be protected and dustproof.
