Detailed Description

The following detailed description of the embodiments of the invention is provided in connection with the accompanying drawings. Aside from the detailed description, the invention is capable of general implementation in other embodiments and its several details are capable of modifications in various obvious respects, all without departing from the scope of the invention, as set forth in the claims below. In the description of the specification, numerous specific details and embodiments are set forth in order to provide a thorough understanding of the present invention; however, these specific details and implementation examples should not be construed as limiting the invention. In other instances, well-known steps or elements have not been described in detail so as not to unnecessarily obscure the present invention.

Fig. 1 is an exploded view of an anti-theft USB connection device 100 according to an embodiment of the present invention. Fig. 2A and 2B are partial perspective views of the anti-theft USB connection device 100 of fig. 1 at two different viewing angles, and some elements are not shown in fig. 2A and 2B.

Referring to fig. 1, fig. 2A and fig. 2B, the anti-theft USB connection device 100 may include a USB connector 110, a locking structure 120, an anti-detachment structure 130, an elastic member 140, a carrying seat 150 and a housing 160. The USB connector 110 may be a connection interface supporting 2.0 or 3.0 transmission specifications, and may include a USB plug 111 and a transmission line 112 electrically connected to the USB plug 111. The USB plug 111 is disposed on the carrying seat 150, and the transmission line 112 passes through the carrying seat 150 and is electrically connected to the USB plug 111.

The locking structure 120 is disposed on the carrying seat 150, and includes a seat body 121 and a locking element 122. The locking member 122 extends from the base 121 and forms a hook at a free end thereof. The carrier 150 may include a protrusion 152, and the protrusion 152 has a notch 151 corresponding to the latch 122. When the locking structure 120 is disposed on the carrier 150, each of the locking elements 122 can extend into the USB plug 111 through the corresponding slot 151. Here, the USB plug 111 has a hook hole 111h corresponding to the fastener 122. When the locking member 122 extends into the USB plug 111 through the corresponding notch 151, the hook portion of the free end of the locking member 122 can extend out of the corresponding hook hole 111 h.

The housing 160 may include a first housing 161 and a second housing 162. The locking structure 120, the anti-detachment structure 130, the elastic element 140 and the carrying seat 150 can be accommodated in the first casing 161 and the second casing 162, and the USB plug 111 passes through an opening formed by a first concave portion (not shown) of the first casing 161 and a second concave portion 162p of the second casing 162 and extends to the outside of the casing 160, so that the hook hole 111h is exposed outside the casing 160. The first shell 161 and the second shell 162 may be combined to form the shell 160, for example, but not limited to, by ultrasonic welding. By fixing the housing 160, the aforementioned components can be stably disposed in the housing 160 without shaking. For example, the first housing 161 may form a first accommodating space (not shown), the second housing 162 may form a second accommodating space 162S, and the protrusion 152 of the bearing seat 150 may be rightly disposed in the accommodating space formed by the first accommodating space and the second accommodating space 162S, so that the bearing seat 150 can obtain a reliable limiting effect in the direction of the X, Y, Z axis.

The elastic element 140 is connected to the locking structure 120 and provides a force for the locking element 122 to protrude from the hook hole 111h of the USB plug 111. Therefore, when the elastic member 140 is in a relaxed state (i.e., the elastic member 140 is not stressed or is stressed less), at least a portion of the locking member 122 (e.g., the hook portion of the free end) protrudes from the hook hole 111 h. In this embodiment, the elastic member 140 may be a spring, such as but not limited to a torsion spring. The elastic members 140 can be abutted against the seat body 121 in the X-axis direction, respectively, so as to absorb tolerance in the X-axis direction, thereby preventing the components from shaking and generating abnormal sound during operation. The elastic member 140 has a first end 141 and a second end 142. The first end 141 is accommodated in the notch 121c of the seat 121, and the second end 142 abuts against the front inner wall 162w of the second shell 162. When the elastic member 140 is under the action of force, the locking member 122 can exit the hook hole 111h, and the elastic member 140 can store the energy of the force; when the force is no longer applied to the elastic member 140, the elastic member 140 releases the stored energy, so as to drive at least a portion (e.g., the hook portion of the free end) of the locking member 122 to extend out of the hook hole 111 h. For example, when the locking structure 120 is forced to rotate counterclockwise on the YZ plane facing the positive direction of the X-axis, the notch 121c of the seat body 121 presses the first end 141 of the elastic element 140, so that the elastic element 140 is twisted to store energy. Once the locking structure 120 is no longer stressed, the elastic member 140 can utilize the stored energy to reversely rotate and reset the locking structure 120.

The anti-detach structure 130 includes a head portion 131 and a shaft portion 132 connected to each other. The elastic member 140 can be sleeved on the rod portion 132. The anti-detaching structure 130 is engaged with the seat body 121 by the rod portion 132, so as to be linked with the locking structure 120. Therefore, when the anti-detaching structure 130 rotates, for example, rotates counterclockwise on the YZ plane facing the positive direction of the X axis, the locking structure 120 is driven to rotate synchronously, so that the locking structure 120 can rotate around the anti-detaching structure 130, and the elastic element 140 stores energy due to the stress. In this embodiment, the shaft 132 may have a threaded section 132a and further include a nut 132 b. A nut 132b is threaded onto the threaded segment 132a and is located at the end of the shank 132 that is connected to the head 131. Correspondingly, the base 121 may have a first through hole 121a, and the shape of the first through hole 121a is matched with that of the nut 132 b. For example, the nut 132b can be a hexagonal nut, and the first through hole 121a can be hexagonal, so that the nut 132b can be matched with the first through hole 121a to be fastened with the seat body 121. In addition, the seat body 121 may further have a second through hole 121b, and the second through hole 121b has a thread, so that the other end of the rod portion 132 can be locked to the seat body 121 by combining the threaded segment 132a with the second through hole 121 b. Therefore, the anti-detachment structure 130 can be coupled with the locking structure 120 and firmly combined with the locking structure 120.

The tamper-evident structure 130 may further include a shim 133. As shown in fig. 2B, a washer 133 is sleeved on the rod 132 and disposed between the flange 131f of the head 131 and the nut 132B to absorb tolerance in the X-axis direction.

Referring to fig. 1 and 2A, the head 131 of the detachment prevention structure 130 has a torque groove (torque access) 131 r. When a tool with a shape matching with the torque groove 131r extends into the torque groove 131r, the tool can apply torque to the head 131, so as to drive the anti-detaching structure 130 to rotate integrally. Here, the torque groove 131r has a special geometric shape, and the shape thereof conforms to a screw groove shape of a safety screw (stud-proof security screw), and a special tool is required to apply a torque to the head 131. For example, the screw groove of the safety screw may be a quincunx (torx), a quincunx with pin (torx with pin), a cross-shaped groove, an offset cross (offset cross), a triangle with post, a square with post, a pentagon with post, a one-way groove (one-way), a double-hole groove, a Y-type, a skew Y-with, an S-shape, but is not limited thereto. That is, the geometry of the torque slot 131r is not a straight, cross or hexagonal shape of a common standard, so that a common straight, cross or hexagon socket screwdriver cannot cooperate with the torque slot 131r to rotate the anti-dismounting structure 130. In addition, the anti-tamper structure 130 is further hidden in the housing 160 and does not protrude from the housing 160 (shown in fig. 3). Here, the head 131 may be exposed from the opening 161h of the first housing 161, and the opening 161h may be smaller than the flange 131f of the head 131, ensuring that the detachment prevention structure 130 does not fall off from the negative direction of the X-axis. The threaded section 132a may be inserted into the insertion hole 162h of the second housing 162 such that the detachment prevention structure 130 is interposed between the first housing 161 and the second housing 162. Furthermore, the head 131 of the anti-detachment structure 130 does not protrude from the housing 160, so that the head cannot be rotated by hand. Therefore, a special tool matched with the geometry of the torque groove 131r of the head 131 must be used to rotate the anti-detaching structure 130, so as to drive the fastener 122 to exit the hook hole 111 h.

In this embodiment, the geometry of the torque slot 131r may be a quincunx with a post, so that a special screwdriver head is needed to rotate. This is merely an example, and the geometry of the torque groove 131r of the present invention is not limited thereto. Furthermore, as the geometry becomes more complex, the difficulty in obtaining a screwdriver becomes greater, and the level of safety can be increased.

Fig. 3 is a schematic diagram illustrating the connection device 100 to be connected to an electronic device 100'. Fig. 4A is a cross-sectional view of the process of inserting the connection device 100 into the electronic device 100'. Fig. 4B is a sectional view of the connecting device 100 in a locked state. Fig. 4C is a sectional view of the connection device 100 in an unlocked state.

Referring to fig. 3, the electronic device 100 'includes a housing 120' and a USB base 110 'exposed from the housing 120' for electrically connecting the anti-theft USB connection device 100 thereto. The USB base 110 'includes a USB socket 111'. When the USB plug 111 is inserted into the USB socket 111 ', the locking member 122 can lock the USB socket 111 ', and even if a pulling force is applied to the anti-theft USB connection device 100 in the Y-axis positive direction, the anti-theft USB connection device 100 cannot be easily separated from the electronic device 100 '.

As shown in fig. 4A, the hook portion of the locking element 122 may have an inclined surface 122a, and the inclined surface 122a will contact with the outer frame 112 'of the USB socket 111' first, so that the locking element 122 is pushed. The USB plug 111 may further have a communication channel 111c, the communication channel 111c is communicated with the hook hole 111h, so that the locking element 122 extends from the hook hole 111h through the communication channel 111c, and the communication channel 111c further provides a space for the locking element 122 to gradually move away from the hook hole 111 h. When the locking member 122 is pushed by the outer frame 112', the locking structure 120 rotates counterclockwise as a whole. At this time, the elastic member 140 gradually stores energy generated by twisting the elastic member 140 due to the rotation of the locking structure 120.

Next, as shown in fig. 4B, when the hook portion of the locking element 122 is no longer pressed by the outer frame 112 'of the USB socket 111', the locking structure 120 rotates clockwise by the energy stored in the elastic element 140, so that the locking element 122 extends out of the hook hole 111h and is locked to the outer frame 112 'of the USB socket 111'. When the anti-theft USB connection device 100 is in the locked state, the plane 122b of the hook portion of the locking member 122 is firmly abutted against the outer frame 112'; on the other hand, the inclined surface 122a also abuts against the elastic arm 113 'of the USB socket 111'.

To separate the anti-theft USB connection device 100 from the electronic device 100', the user may rotate the anti-tamper structure 130 using a special tool that mates with the geometry of the torque groove 131r of the head 131 of the anti-tamper structure 130. As shown in fig. 4C, the user can utilize the special tool to rotate the anti-detaching structure 130 counterclockwise, so as to drive the locking member 122 to exit from the hook hole 111 h. Thus, the locking member 122 is no longer locked to the outer frame 112 'of the USB socket 111', and the anti-theft USB connection device 100 can be removed.

FIG. 5 is an exploded view of the anti-theft USB connection device 200 according to another embodiment of the present invention. Fig. 6A and 6B are partial perspective views of the anti-theft USB connection device 200 of fig. 5 at two different viewing angles, and some elements are not shown in fig. 6A and 6B.

Referring to fig. 5, fig. 6A and fig. 6B, the anti-theft USB connection device 200 may include a USB connector 210, a locking structure 220, an anti-detachment structure 230, an elastic member 240, a carrying seat 250 and a housing 260. The USB connector 210 may be similar to the aforementioned USB connector 110, wherein the transmission line 212 is connected to each electrical connection portion 211e of the USB plug 211 by soldering, for example.

Referring to fig. 5, fig. 6A and fig. 6B, the supporting base 250 may include a front wall 254, a base 253 and side ears 251 and 252 at two sides of the base 253. The front wall 254 of the carrier 250 and the housing 260 can be combined by, for example, but not limited to, ultrasonic welding to enclose the components (such as the locking structure 220, the anti-detachment structure 230, the elastic member 240, etc.) contained in the housing 260. The USB plug 211 is disposed on the carrying seat 250 and extends outside through the opening 254p of the front wall 254, so that the hook hole 211h (shown in fig. 7) is exposed.

The locking structure 220 is disposed on the bearing seat 250, and includes a seat body 221 and a locking member 222. The locking member 222 extends from the base 221 and forms a hook at a free end thereof. The base 253 of the supporting base 250 may have an accommodating groove 253c, and two side portions of the base body 221 having the first through hole 221a and the second through hole 221b may be respectively accommodated in the accommodating groove 253 c. The latch 222 may extend through the opening 254p of the front wall 254 toward the inside of the USB plug 211, and the hook portion thereof may protrude from the corresponding hook hole 211h (shown in fig. 7).

The elastic member 240 is connected to the locking structure 220, and functions as the elastic member 140, which will not be described again. In this embodiment, the elastic member 240 may be a spring, such as but not limited to a compression spring. The elastic member 240 is connected to the base 221 and the carrying base 250, respectively. Further, one end of the elastic element 240 is connected to the seat 221, and the other end is connected to the base 253 of the carrying seat 250. In one embodiment, the anti-theft USB connection device 200 may further include a support pillar 270. The support column 270 may include a cylinder 271 and an end seat 272. The cylinder 271 can pass through the circular hole 253h of the base 253 and the circular hole 221c of the seat body 221 from the bottom of the base 253 of the carrying seat 250, so as to be sleeved by the elastic member 240, and further assist the elastic member 240 to be positioned between the seat body 221 and the carrying seat 250. The support column 270 may be coupled to the base 253 by an end mount 272. In other embodiments, the supporting posts 270 can be integrally formed with the supporting base 250.

Similar to the anti-detachment structure 130, the anti-detachment structure 230 is engaged with the seat body 221 via the rod portion 232 to be linked with the locking structure 220. The head 231 is connected to the first end 232a of the stem 232. In this embodiment, the shaft portion 232 can include a cylindrical structure 232c disposed between the first end 232a and the second end 232b of the shaft portion 232. The second end 232B of the rod portion 232 can sequentially pass through the through hole 251h of the side ear portion 251, the first through hole 221a of the seat body 221, the second through hole 221B of the seat body 221, and the through hole 252h of the side ear portion 252, such that the second end 232B passes through the through hole 252h of the side ear portion 252, as shown in fig. 6B. In contrast, the head 231 abuts against the side ear 251 and does not pass through the through hole 251h of the side ear 251, as shown in fig. 6A and 6B.

The shapes of the first through hole 221a and the second through hole 221b of the base 221 can be matched with the pillar-shaped structure 232 c. For example, the columnar structure 232c may be a hexagonal column, and the first through hole 221a and the second through hole 221b may be hexagonal, so that the columnar structure 232c can be inserted through the first through hole 221a and the second through hole 221b of the seat 221, and simultaneously, just match with the first through hole 221a and the second through hole 221b to be fastened with the seat 221. Thus, the detachment prevention structure 230 can be coupled with the locking structure 220.

In addition, the anti-detach structure 230 may further include a fastener 233. As shown in fig. 5 and 6B, the fastener 233 can be fastened to the second end 232B of the rod portion 232 passing through the through hole 252h of the side ear 252, so as to prevent the anti-detaching structure 230 from moving along the negative direction of the X axis and prevent the rod portion 232 from coming out of the seat body 221 along the negative direction of the X axis. In other embodiments, however, the fastener 233 may be omitted. For example, the second end 232b of the rod 232 and the head 231 can respectively abut against the housing 260, so that the housing 260 limits the movement of the anti-detach structure 230 in the X-axis direction.

Referring to fig. 5 and 6A, the head 231 of the detachment prevention structure 230 has a torque groove 231 r. The shape and function of the torque groove 231r are as described above for the torque groove 131r, and a description thereof will not be repeated. In addition, the anti-tamper structure 230 is further hidden in the housing 260 and does not protrude from the housing 260 (fig. 7). Here, the head 231 may be exposed from the opening 260h of the housing 260, and the opening 260h may be smaller than the maximum outer diameter of the head 231, ensuring that the detachment prevention structure 230 does not fall off from the negative direction of the X-axis. The head 231 of the anti-detach structure 230 does not protrude from the housing 260 and thus cannot be rotated by hand. Therefore, a special tool matched with the geometry of the torque groove 231r of the head 231 must be used to rotate the anti-detaching structure 230, so as to drive the fastener 222 to exit the hook hole 211 h.

Fig. 7 is a schematic diagram of the connection device 200 to be connected with an electronic device 200'. Fig. 8A is a sectional view of a process in which the connection device 200 is inserted into the electronic device 200'. Fig. 8B is a sectional view of the connector 200 in a latched state. Fig. 8C is a sectional view of the connection device 200 in the unlocked state.

Referring to fig. 7, the electronic device 200 'includes a housing 220' and a USB base 210 'exposed from the housing 220' for electrically connecting the anti-theft USB connection device 200 thereto. The USB cradle 210 'includes a USB socket 211'. When the USB plug 211 is inserted into the USB socket 211 ', the locking member 222 can lock the USB socket 211 ', and even if a pulling force is applied to the anti-theft USB connection device 200 in the Z-axis negative direction, the anti-theft USB connection device 200 cannot be separated from the electronic device 200 '.

As shown in fig. 8A, the hook portion of the locking element 222 may have an inclined surface 222a, and the inclined surface 222a will contact the outer frame 212 'of the USB socket 211' first, so that the locking element 222 is pushed. Here, the USB plug 211 may further have a communication channel 211c, the communication channel 211c is communicated with the hook hole 211h, so that the locking element 222 extends from the hook hole 211h through the communication channel 211c, and the communication channel 211c further provides a space for the locking element 222 to gradually move away from the hook hole 211 h. When the locking member 222 is pushed by the outer frame 212', the locking structure 220 rotates counterclockwise as a whole. At this time, the elastic member 240 gradually stores energy generated by the rotation of the locking structure 220 to compress the elastic member 240.

Next, as shown in fig. 8B, when the hook portion of the locking element 222 is no longer pressed by the outer frame 212 'of the USB socket 211', the locking structure 220 rotates clockwise by the energy stored in the elastic element 240, so that the locking element 222 is locked in the hook hole 211h and locked in the outer frame 212 'of the USB socket 211'. When the anti-theft USB connecting device 200 is in the locked state, the plane 222b of the hook portion of the locking member 222 is firmly abutted against the outer frame 212'.

To separate the anti-theft USB connecting device 200 from the electronic device 200', the user can rotate the anti-tamper structure 230 using a special tool that mates with the torque groove 231r geometry of the head 231 of the anti-tamper structure 230. As shown in fig. 8C, the user can use the special tool to rotate the anti-detachment structure 230 counterclockwise, so as to drive the locking member 222 to exit from the hook hole 211 h. Thus, the locking member 222 is no longer locked to the outer frame 212 'of the USB socket 211', and the anti-theft USB connecting device 200 can be removed.

As shown in the foregoing embodiments of fig. 4B, 4C, and fig. 8B and 8C, when the anti-theft USB connecting device 100, 200 respectively assumes the locking state and the unlocking state, the locking structures 120, 220 only slightly rotate, for example, by an angle difference of about 5 °, and no excessive shaking occurs to cause a possibility of misalignment between the other structures.

The electronic devices 100 ', 200' may be any one of the following devices: the home broadband access device supporting EASY MESH, the enterprise-level intelligent switch, the wireless access point using 6GHz unauthorized frequency band, the 5G gigabit mobile access home gateway, the home gateway supporting 4 x 411 ax WiFi, the hybrid set-top box supporting AV1 decoding and 11ax WiFi, the enterprise-level wireless network access point and the enterprise-level network router. That is, the anti-theft USB connection device 100, 200 of the present invention can be used with any of the aforementioned devices.

As mentioned above, the torque groove of the head of the anti-tamper structure is a screw groove conforming to the safety screw, rather than a straight, cross or hexagonal shape of a common standard specification, so that a special tool capable of matching with the geometric shape of the torque groove is required to apply torque to the head to rotate the anti-tamper structure to release the locking state of the locking structure, thereby improving the anti-theft effect.

The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
