Detailed Description

The present application is described in further detail below with reference to figures 2-3.

The embodiment of the application discloses a USB shutoff subassembly. With reference to fig. 2 and 3, the blocking assembly comprises a safety lock 2 and a key 3 for removing the safety lock 2 from the USB socket 1.

The safety lock 2 is a shell structure with an opening at one end, and the opening of the safety lock 2 faces the USB socket 1. The outer wall of the safety lock 2 is provided with a yielding hole 21, an elastic clamping tongue 22 is integrally arranged on the hole wall of the yielding hole 21 deviating from the USB socket 1, and a clamping block 23 used for being matched with the key 3 for use is integrally arranged on the clamping tongue 22.

The key 3 comprises a holding part 31 and an extending part 32, and the extending part 32 is provided with a clamping groove 321 matched with the clamping block 23 for use.

The end wall of the safety lock 2 departing from the opening direction is provided with a locking notch 24 for the extending part 32 to extend into the abdicating hole 21. The locking notch 24 has the same cross-section as the protruding portion 32.

Referring to fig. 2 and 3, when the safety lock 2 is inserted into the USB socket 1, so that one end of the latch 22, which is far away from the hole wall of the abdicating hole 21, extends into the latch hole 12 of the USB socket 1 under the elastic action of the latch 22, and abuts against the inner side wall of the latch hole 12, the position of the safety lock 2 is named as a first setting position, at this time, the latch 22 is latched on the inner wall of the latch hole 12 in the USB socket 1, and the safety lock 2 is latched in the inner cavity of the USB socket 1 through the latch 22.

When the key 3 is inserted into the fore shaft 24 until the clamping block 23 enters the clamping groove 321, and the bottom end of the clamping block 23 abuts against the inner wall of the clamping groove 321, the position of the key 3 is named as a second setting position, and the clamping block 23 of the safety lock 2 is clamped in the clamping groove 321 of the key 3 at this time.

When the USB socket is used, a user firstly inserts the safety lock 2 into a first set position, so that the clamping tongue 22 of the safety lock 2 is clamped in the clamping hole 12 to plug the USB socket 1, and other people are prevented from stealing data or files in equipment through the USB socket 1; when a user needs to start the USB socket 1 again to transmit files, the key 3 extends into the lock opening 24 to a second set position, the safety lock 2 is clamped in the clamping groove 321 of the key 3 through the clamping block 23, then the key 3 is pulled to take the safety lock 2 out of the USB socket 1, the USB socket 1 is removed from being blocked by the safety lock 2, and therefore normal use of the USB socket 1 is recovered.

Referring to fig. 2 and 3, the structure of the safety lock 2 is fitted with the inner cavity of the USB socket 1, when the safety lock 2 is located at the first setting position, the outer wall of the safety lock 2 is attached to the inner side wall of the USB socket 1, and the outer wall of the data plug 11 is attached to the inner wall of the safety lock 2. Since the position of the data plug 11 is generally located at the top of the cavity of the USB socket 1. The bottom wall thickness of the inner cavity of the safety lock 2 is greater than the top wall thickness.

The abdicating holes 21 are formed in the lower surface of the safety lock 2, the clamping tongues 22 are two in number, the two clamping tongues 22 correspond to the two clamping holes 12 in the bottom wall of the USB socket 1 one by one, the two clamping blocks 23 in the same shape are located on the top of the side wall of the two clamping tongues 22 facing each other, and the bottom of one end, away from the hole wall of the abdicating hole 21, of each clamping tongue 22 extends downwards into the clamping hole 12 in the bottom wall of the USB socket 1.

Because the bottom wall of the safety lock 2 is thicker, the thickness of the clamping tongue 22 on the bottom wall is allowed to be processed to be thicker, the moving space of the clamping tongue can be more sufficient, and the deformation resistance of the corresponding clamping tongue 22 can be improved.

Referring to fig. 2 and 3, the thickness of the catching block 23 is about half of the thickness of the catching tongue 22. A first inclined surface 231 is arranged between the lower surface of the clamping block 23 and the surface of the clamping block 23 facing the locking notch 24, and the first inclined surface 231 is arranged away from the center of the safety lock 2; a second inclined surface 322 is provided between the upper surface of the key 3 and the end surface of the protruding portion 32 away from the grip portion 31, and the second inclined surface 322 is inclined in the same direction as the first inclined surface 231.

When the key 3 is inserted into the second setting position from the lower part of the clamping block 23, the first inclined surface 231 and the second inclined surface 322 are mutually abutted, so that the clamping block 23 and the key 3 can more conveniently slide relatively, the clamping tongue 22 is propped to deform upwards, and the key 3 can more favorably extend into the second setting position.

The depth of the slot 321 is smaller than the height of the clamping block 23. Specifically, the difference between the thickness of the clamping block 23 and the depth of the clamping groove 321 is not less than the length of the clamping tongue 22 extending into the clamping hole 12.

When the key 3 is in the second setting position, the bottom of joint piece 23 is inconsistent with draw-in groove 321 diapire of key 3, under the support of draw-in groove 321 diapire, joint piece 23 can upwards produce deformation with block tongue 22, the tip that the hole wall 21 hole of stepping down was kept away from to block tongue 22 at this moment deviates from corresponding joint hole 12 along with the production of deformation, safety lock 2 no longer through block tongue 22 joint in USB socket 1, safety lock 2 deviates from USB socket 1 under the drive of key 3 more easily, thereby it is when using key 3 to pull out safety lock 2, the condition of damage such as fracture takes place for block tongue 22 to have reduced the user.

Referring to fig. 3, the locking notch 24 extends down to the lower surface of the security lock 2. When the key 3 is in the second setting position, the lower surface of the key 3 is directly contacted with the bottom wall of the USB socket 1, and the two latch tongues 22 are respectively positioned at two sides of the key 3. When the user pulls the safety lock 2 out of the USB socket 1, the key 3 can be directly taken out from the lower part of the safety lock 2, so that the safety lock 2 and the key 3 can be separated more conveniently.

Furthermore, in order to increase the range of motion and the deformable area of the latch 22, the abdicating hole 21 is communicated with the inner cavity of the safety lock 2; in order to facilitate the user to insert the safety lock 2 into the USB socket 1, a necking structure 25 is provided on the outer wall of the end of the safety lock 2 extending into the USB socket 1. The inner edge of the throat formation 25 is of constant size and the outer edge tapers in a direction away from the mouth 24.

The implementation principle of the USB plugging component in the embodiment of the application is as follows:

when a user does not need to use the USB socket 1, the user firstly inserts the safety lock 2 into the first setting position of the USB socket 1, the safety lock 2 is clamped in the USB socket 1 through the clamping tongue 22 to seal the USB socket 1, and therefore other people are prevented from stealing important data or files in the equipment through the USB socket 1.

When a user needs to transmit files through the USB socket 1, the key 3 extends into the lock opening 24 and is inserted into the second set position, the safety lock 2 is clamped in the clamping groove 321 of the key 3 through the clamping block 23, the clamping tongue 22 is upwards deformed under the support of the key 3 and is completely separated from the clamping hole 12, the key 3 is pulled to take the safety lock 2 out, the USB socket 1 is further plugged by the safety lock 2, and normal use of the USB socket 1 is recovered.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
