Detailed Description

The embodiments of the present invention will be described with reference to fig. 1 to 6.

In the first embodiment, the first step is,

as shown in fig. 1-3 and 4, a capless USB protective socket structure includes a mounting portion 2 installed at a socket of a USB female socket 1, the mounting portion 2 has an opening 21, the opening 21 expands under a stressed condition to allow a USB male connector 4 to pass through the opening 21 and be inserted into the socket of the USB female socket 1, and the opening 21 is closed under an unstressed condition to close the socket of the USB female socket 1.

The opening 21 comprises a flexible diaphragm 22, a gap 23 is formed between the flexible diaphragm 22 and the main body of the mounting part 2, the gap 23 is C-shaped, and when the flexible diaphragm 22 and the main body of the mounting part 2 are in a stressed state, the distance between the flexible diaphragm 22 and the main body of the mounting part 2 at the gap 23 is gradually increased so that the opening 21 is expanded; when the stressed state is converted into an unstressed state, the distance between the flexible diaphragm 22 and the main body of the mounting portion 2 at the slit 23 is gradually reduced under the elastic action of the flexible diaphragm 22 itself to close the opening 21.

The mounting structure further comprises a shell 3, the mounting part 2 is fixed in a groove 31 of the shell 3, the groove 31 penetrates through the shell 3, the mounting part 2 is provided with an annular convex edge 24 matched with the inner wall of the groove 31, and the mounting part 2 can be fixed in the shell 3 through plastic coating. The mounting portion 2 is made of a soft elastic plastic material, and the housing 3 is made of a hard material (e.g., hard plastic, metal, etc.). The shell 3 is used for being connected with an equipment panel, and the installation part 2 is connected with the USB female socket 1.

The mounting part 2 is provided with a mounting groove 25 at the rear side of the opening 21, and the socket end of the USB female socket 1 is embedded in the mounting groove 25.

The thickness of the flexible membrane 22 at the gap 23 accounts for one seventh to one fifth of the width of the socket of the USB female socket 1.

In the second embodiment, the first embodiment of the method,

as shown in fig. 1 to 3 and 5, the difference from the first embodiment is that the opening 21 includes two flexible diaphragms 22, a gap 23 between the flexible diaphragm 22 and the main body of the mounting portion 2 extends between the two flexible diaphragms 22 so that the two flexible diaphragms 22 can be separated from each other under a force, and the gap 23 is H-shaped. The two flexible diaphragms 22 are symmetrically arranged on two sides of the USB female socket 1 in the width direction. The sides of the two flexible membranes 22 facing the USB male connector 4 are flat, so that the two flexible membranes 22 form a complete plane on the sides, which is lower than the end surface of the mounting portion 2 to form a flat-bottomed groove.

In the third embodiment, the first step is that,

according to a further improvement of the second embodiment, the flexible membrane 22 is provided with a slope 27 inclining to the gap 23 on the side far away from the socket of the USB female socket 1, and the two slopes 27 of the two flexible membranes 22 form a V-shaped guide surface.

In the fourth embodiment, the first step is that,

as shown in fig. 1-3 and 6, the fourth embodiment is a preferred embodiment, and differs from the first, second and third embodiments in that the opening 21 includes two flexible diaphragms 22, a gap 23 between the flexible diaphragms 22 and the main body of the mounting portion 2 is only provided between the two flexible diaphragms 22, and the gap 23 is a straight-line-shaped gap 23.

The two flexible diaphragms 22 are symmetrically arranged on two sides of the width direction of the socket of the USB female socket 1, the side surface of the flexible diaphragm 22 far away from the socket of the USB female socket 1 is provided with an inclined surface 27 inclined towards the gap 23, and the two inclined surfaces 27 of the two flexible diaphragms 22 form a V-shaped guide surface. The two flexible diaphragms 22 have a transition contour 26 therebetween. When the USB male connector 4 is inserted from the opening 21, the USB male connector 4 stretches the two flexible diaphragms 22 at the gap 23, and at this time, the two flexible diaphragms 22 and the two transition arc surfaces 26 are equivalently sleeved at the front end of the USB male connector 4.

The fourth embodiment may also be developed, that is, the straight slit 23 between the two flexible diaphragms 22 extends to the connection between the flexible diaphragm 22 and the transition arc 26 to form an H-shaped slit 23, so as to reduce the resistance of the USB male connector 4 when inserted into the opening 21.

In the fifth embodiment, the first step is,

the difference from the first embodiment is that the mounting part 2 is integrally injection moulded on the housing 3, both the housing 3 and the mounting part 2 being made of a soft, resilient plastic material.

The utility model has reasonable structure, novel design and strong practicability, the elastic installation part 2 forms an opening 21 which is normally closed and can be expanded when stressed at the socket of the USB female socket 1 through the flexible membrane 22, and under the normal state of no stress, the opening 21 automatically closes under the elastic action of the flexible membrane 22 to play the functions of water resistance and dust resistance; when receiving external force, when public head 4 of USB inserts from opening 21 to female seat 1 socket of USB promptly, public head 4 front end of USB begins to strut flexible diaphragm 22 from gap 23 department, and opening 21 expansion makes public head 4 of USB insert smoothly to female seat 1 of USB and charge or data transmission to can cancel sealed lid, convenience of customers' operation is used, has reduced the required technological requirement of connector product production and assembly.

The above is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications to the above embodiments are all within the scope of the present invention.
