[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
[0047] Example 1:
[0048] like Figure 1-5 As shown, the utility model provides an anti-loosening USB interface device, which includes:
[0049] The plug portion 1 is made entirely of metal and is used to plug into and mate with the electronic device port 13. A notch 6 is provided on the side of the plug portion 1 facing in the Y direction.
[0050] The adapter portion 2 is connected to the plug portion 1 and is hollow inside. Specifically, in this embodiment, the end of the plug portion 1 can be inserted into the adapter portion 2 along the X direction and connected by bonding or other means.
[0051] The housing 3 is formed by a first Y-direction side plate 31 and a second Y-direction side plate 32 that are arranged opposite to each other in the Y direction, a top plate 33 connecting the upper end surfaces of the first Y-direction side plate 31 and the second Y-direction side plate 32, and a rear side plate 34 connecting the rear ends of the first Y-direction side plate 31 and the second Y-direction side plate 32, and has a front opening 35, a lower opening 36 and an internal accommodating space (not shown). At the same time, as shown in FIG. Figure 5 As shown, the rear side plate 34 is provided with a housing through hole 341;
[0052] The supporting plate 4 is entirely located in the internal accommodation space of the housing 3 and is used to support the adapter 2;
[0053] a button 8 mounted on the side of the adapter 2 facing in the Y direction, and the adapter 2 and the button 8 are all accommodated in the internal accommodation space of the housing 3;
[0054] A connecting rod 5, one end of which extends into the adapter 2 and is connected to the button 8, and the other end is accommodated in the notch 6 and is freely suspended;
[0055] The block 7 is connected to the outer wall surface of the freely suspended end of the connecting rod 5 and partially / completely extends to the outside of the plug portion 1. In this embodiment, the connecting rod 5 and the block 7 can be integrally formed and both have a sheet-like structure and can be made of metal or plastic. The connecting rod 5 can be bent and deformed. The plug portion 1 and the block 7 are both located outside the adapter portion 2 and extend from the front opening 35, so that the plug portion 1 and the block 7 are simultaneously located outside the housing 3. In this embodiment, the block 7 has an overall wedge-shaped structure.
[0056] A bayonet 10 is provided in a port 13 of an electronic device plugged into the plug portion 1 and can be engaged with the card block 7;
[0057] and a locking device for locking the housing 3 so that the support plate 4, the adapter 2 and the button 8 are continuously located in the internal accommodation space of the housing 3;
[0058] In this embodiment, the length direction, width direction and height direction (i.e., thickness direction) of the adapter part 2 correspond to the X direction, Y direction and Z direction, the direction where the plug part 1 is located is the "front", and the opposite direction, where the rear side panel 34 is located is the "rear".
[0059] Specifically, the locking device includes:
[0060] A locking plate 9 having a locking hole 91 formed therein, one end of which is connected to the support plate 4 and the other end of which passes through the housing through hole 341 , and the locking hole 91 is located outside the housing 3 ;
[0061] And a lock 11 passes through the lock hole 91 to lock the housing 3 and the locking plate 9.
[0062] During use, the plug portion 1 is plugged into the electronic device port 13, and at the same time, the clamping block 7 is engaged with the clamping notch 10 on the electronic device port 13, thereby fixing the plug portion 1. At this time, the button 8 is located inside the housing 3 and cannot be pressed. Therefore, the clamping block 7 and the clamping notch 10 can firmly fix the position of the plug portion 1 and the electronic device port 13, preventing the plug portion 1 from being separated from the electronic device port 13, thereby avoiding data transmission interruption.
[0063] When it is necessary to separate the plug portion 1 and the electronic device port 13, the lock 11 on the housing 3 and the locking plate 9 must first be released, and the support plate 4, the locking plate 9, and the adapter portion 2 on the support plate 4 must be pulled out of the housing 3, so that the button 8 is exposed outside the housing 3. Furthermore, the button 8 is pressed by external force to move the connecting rod 5 and the clamping block 7 synchronously toward the inside of the plug portion 1, so that the clamping block 7 is disengaged from the clamping hole 10 of the electronic device port 13, and the plug portion 1 can be separated from the electronic device port 13.
[0064] After the button 8 is released from being pressed, the button 8 automatically resets to drive the connecting rod 5 and the block 7 to move synchronously toward the outside of the plug portion 1 , so that the connecting rod 5 and the block 7 return to their initial positions.
[0065] Furthermore, the plug part 1 is provided with a slot 6 on both sides in the Y direction. Correspondingly, there are two groups of connecting rods 5, card blocks 7, and buttons 8. By pressing each button 8, a connecting rod 5 and a card block 7 are driven to move synchronously into the inside of the plug part 1.
[0066] Therefore, the USB interface device in this embodiment has a simple structural design. It can achieve a firm connection with the electronic device port 13 through the card block 7, and at the same time, the button 8 is protected by the shell 3. Before the user is unable to release the lock 11 on the shell 3 and the lock plate 9, the plug part 1 and the electronic device port 13 cannot be separated by pressing the button 8, thereby avoiding data transmission interruption.
[0067] At the same time, no other components are arranged around the electronic device port 13 , so there is no sight obstruction, which makes it easy for the user to align the plug part 1 with the electronic device port 13 at one time and complete the plug-in connection.
[0068] Example 2:
[0069] The only difference between this embodiment and embodiment 1 is that Figure 6-7 As shown, the button 8 includes:
[0070] A pressing portion 81 is mounted on the side of the adapter 2 in the Y direction, and the pressing portion 81 partially extends from the adapter 2 to facilitate pressing. At the same time, one end of the connecting rod 5 is connected to the pressing portion 81. Preferably, a protrusion 811 is formed on the outer surface of the pressing portion 81 to increase friction and facilitate the user's pressing operation.
[0071] And a mounting rod 82, which is located inside the adapter part 2, and one end of which is connected to the pressing part 81, and the other end is connected to the inner wall surface of the adapter part 2 by screw connection, bolt connection, bonding, welding, etc.; the mounting rod 82 is a sheet structure that can be bent and deformed, and is made of metal or plastic.
[0072] like Figure 8 As shown, move the plug portion 1 toward the electronic device port 13 (i.e., along Figure 8 In the direction indicated by the solid arrow in part (a), when the block 7 contacts the inner wall of the electronic device port 13, the connecting rod 5 bends under the pressure of the inner wall of the electronic device port 13 until the block 7 moves to be completely accommodated in the bayonet 10. The pressure of the inner wall of the electronic device port 13 on the connecting rod 5 is released, the connecting rod 5 returns to its original shape, and the block 7 is completely engaged in the buckle 10 (as shown in FIG. Figure 8 As shown in part (b) of the figure), the plug portion 1 is snap-fitted with the electronic device port 13, and the button 8 is located inside the housing 3 and cannot be pressed.
[0073] When the plug part 1 and the electronic device port 13 need to be separated, the lock 11 on the housing 3 and the locking piece 9 must be released first, so that the housing 3 and the support plate 4 are separated from each other, and the button 8 is further exposed. Figure 8 As shown in part (c), by pressing with external force (i.e. along Figure 8 The pressing portion 81 (in the direction indicated by the solid arrow in part (c)) causes the mounting rod 82 to bend and deform, thereby driving the connecting rod 5 and the clamping block 7 to move synchronously toward the inside of the plug portion 1, thereby causing the clamping block 7 to disengage from the clamping slot 10 of the electronic device port 13;
[0074] like Figure 8 As shown in part (d), in the direction away from the electronic device port 13 (i.e., along Figure 8 The adapter part 2 is pulled in the direction indicated by the solid arrow in part (d) until the connecting rod 5 and the block 7 are completely disengaged from the electronic device port 13, so that the plug part 1 can be completely disengaged from the electronic device port 13. At this time, after the pressing portion 81 is released, the mounting rod 82 automatically resets, thereby driving the connecting rod 5 and the block 7 to move synchronously toward the outside of the plug part 1, so that the connecting rod 5 and the block 7 return to their initial positions.
[0075] Example 3:
[0076] The difference between this embodiment and embodiment 1 or 2 is that Figure 1-2 , as shown in FIG9 , the free ends of the first Y-direction side plate 31 and the second Y-direction side plate 32 are bent toward the inside of the housing 3 to form a first receiving portion 311 and a second receiving portion 321 respectively, thereby supporting the entire weight of the support plate 4 and the adapter 2 through the first receiving portion 311 and the second receiving portion 321;
[0077] At the same time, in this embodiment, the shell 3 is made of a heat-conducting metal material as a whole to dissipate the heat generated by the adapter 2 when the USB connector is working. At the same time, the lower opening 36 can further enhance the heat exchange between the internal accommodating space and the external environment, thereby improving the heat dissipation effect.
[0078] Furthermore, the lock 11 can be a mechanical lock or a password lock. Therefore, people without operating authority cannot unlock the lock 11 and press the button 8 before they know the password of the password lock or have the key to the mechanical lock, thereby preventing people without operating authority from plugging and unplugging the USB data cable at will.
[0079] In addition, in this embodiment, the height of the connecting rod 5 is less than the height of the slot 6, and the height of the block 7 is less than the height of the connecting rod 5. Therefore, the connecting rod 5 and the block 7 can move through the slot 6 without hindrance, and their movement will not be obstructed due to contact with the slot 6.
[0080] Example 4:
[0081] The only difference between this embodiment and any one of embodiments 1-3 is that Figure 2 As shown, the support plate 4 is an L-shaped structure as a whole, which includes a bottom plate 41 and a vertical plate 42 vertically connected to the bottom plate 41. In this embodiment, the bottom plate 41 and the vertical plate 42 can be formed by bending the same plate;
[0082] Among them, Figure 1 , 9, the bottom plate 41 is mounted on the first receiving portion 311 and the second receiving portion 321, and at the same time, Figure 2 As shown, the locking piece 9 is connected to the free end of the base plate 41 and can be integrally formed with the base plate 41; the vertical plate 42 is used to close the front end opening 35 of the shell 3, and is provided with a vertical plate through hole 421 for the plug part 1 and the card block 7 to pass through, thereby preventing dust, foreign matter, etc. from entering the interior of the shell 3 through the vertical plate 42 to affect the normal operation of the USB interface.
[0083] Further, such as Figure 5 As shown, the rear side panel 34 is further provided with a cable through hole 342 for the data transmission line 12 to pass through.
[0084] To sum up, the USB interface device in this application has a simple structural design. It can achieve a firm connection with the port of the electronic device through a card block, and at the same time protect the button through the shell. Before the user unlocks the shell and the lock plate, the plug part and the electronic device port cannot be separated by pressing the button, thereby avoiding data transmission interruption.
[0085] At the same time, there are no other components around the electronic device port, and there will be no line of sight obstruction, which makes it easy for the user to align the plug with the electronic device port at one time and complete the plug-in connection. Personnel without operating authority cannot unlock the lock and press the button before knowing the password of the password lock or having the key of the mechanical lock, thereby preventing personnel without operating authority from plugging and unplugging the USB data cable at will.
[0086] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
