Description

Technical Field

[0001] This utility model relates to the field of USB technology, and in particular to a USB connector with an anti-disconnection structure. Background Technology

[0002] USB (Universal Serial Bus) is a standard interface widely used for connecting electronic devices. USB has many outstanding advantages. First, it supports plug-and-play and hot-swapping, making it extremely convenient to use. No complicated installation programs are required, and devices can be connected or disconnected at any time without affecting computer operation. Second, it has fast transmission speeds. USB 3.0 and later versions have significantly improved data transfer rates, meeting the needs of fast transfer of large files. It can also provide a certain power supply to connected devices, facilitating the use of low-power devices. USB has a variety of interface types, the most common being USB-A, USB-B, and USB-C. Among them, USB-C has a reversible plug-and-play feature, making it even more convenient.

[0003] The USB connector is an important interface for data transfer and power supply between devices. It typically consists of a metal contact part and a plastic body.

[0004] In daily work, we have found that existing USB connectors are usually simply inserted into the interface, relying solely on the friction between the two to maintain connection stability. However, under external pulling, vibration, or frequent plugging and unplugging, they are prone to detachment, causing inconvenience to users and affecting the normal operation of devices and secure data transmission. This leads to the problem that existing USB connectors are easily detached from the interface due to external forces and other factors. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that are easily detached due to external forces and other factors, and to propose a USB connector with an anti-detachment structure.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a USB connector with an anti-disconnection structure, comprising a connector, a connector head, and an anti-disconnection device. The connector head is located on one side of the connector and is inserted into the inner wall of the connector. A circuit is provided on one side of the connector head. The anti-disconnection device is disposed on the surface of the connector head and includes a square frame. The square frame is fixedly connected to the surface of the connector and sleeved with the connector. Hollow plates are fixedly connected to both sides of the connector head. Two locking rods are slidably connected to the inner wall of the hollow plates, and the surfaces of the locking rods are fixedly connected to... The device includes a wedge block, a spring fixedly connected to the side of the locking rod corresponding to the inner wall of the hollow block, a control component slidably connected to the inner wall of the hollow plate, four sets of slots on the surface of the square frame, the locking rod engaging with the inner wall of the slots, and a support assembly between the connector and the square frame. When connecting the connector to the connector, the control component can push the wedge block, causing the wedge block to move and the spring to be stressed. The connector can then be inserted into the connector, and the locking rod into the slot. Releasing the control component allows the spring to reset the locking rod and wedge block, with the locking rod abutting against the inner wall of the slot, thus preventing detachment.

[0007] Preferably, the control component includes a sliding plate, which is slidably connected to the inner wall of the hollow plate. Two push blocks are fixedly connected to the lower surface of the sliding plate. By pushing the sliding plate through the above components, the sliding plate can drive the push blocks to move, and the push blocks can cooperate with the inclined blocks to drive the lever to move.

[0008] Preferably, there are multiple springs, which are evenly distributed between the lever and the inner wall of the hollow plate. Through the above-mentioned components, the multiple springs can push the lever evenly, and at the same time, the multiple springs can keep the lever stable.

[0009] Preferably, the support component includes six protrusions, which are fixedly connected to the four sides of the square frame. Two support blocks are fixedly connected to the upper and lower surfaces of the connector, and support blocks are fixedly connected to the other two sides of the connector. With the above components, when the connector is connected to the connector, support blocks one and support blocks two can fit against the surfaces of the square frame and the protrusions respectively. When the connector is subjected to thrust, support blocks one and support blocks two, together with the square frame and the protrusions, can play a supporting and reinforcing role, reducing the possibility of the connector being easily deformed due to stress, thus affecting its use.

[0010] Preferably, both support block one and support block two are arranged in a right-angled trapezoidal shape.

[0011] Preferably, cylindrical rods are fixedly connected to the surfaces of support block one and support block two, and circular holes are opened on the surface of the protrusion. The cylindrical rods are inserted into the inner wall of the circular holes. Through the above-mentioned components, the cylindrical rods on the surfaces of support block one and support block two are inserted into the circular holes, which can strengthen support block one and support block two.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting an anti-disconnection device, the USB connector can be positioned after it is inserted into the interface, effectively reducing the risk of the USB connector accidentally coming out of the interface due to external impact, pulling, or device movement. This ensures the stability of the overall connection, reduces the phenomenon of frequent plugging and unplugging due to detachment, which causes wear and tear on the USB connector and interface, affecting its lifespan, and thus improves the overall usability of the device.

[0014] In this invention, by setting up a support component, the four sides of the USB connector can be supported respectively, reducing the possibility of deformation and damage to the USB after being subjected to force on the four sides, thereby improving the overall strength of the device.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a USB connector with an anti-disconnection structure, including a connector 1, a connector head 2 and an anti-disconnection device 4. The connector head 2 is located on one side of the connector 1 and is inserted into the inner wall of the connector 1. A line 3 is provided on one side of the connector head 2, and the anti-disconnection device 4 is provided on the surface of the connector head 2.

[0023] Specifically, the anti-detachment device 4 includes a square frame 41, which is fixedly connected to the surface of the connector 1 and sleeved with the connector 1. Hollow plates 42 are fixedly connected to both sides of the connector 2. Two locking rods 45 are slidably connected to the inner wall of the hollow plate 42. An inclined block 47 is fixedly connected to the surface of the locking rod 45. A spring 46 is fixedly connected to the side of the locking rod 45 corresponding to the inner wall of the hollow block. A control component 44 is slidably connected to the inner wall of the hollow plate 42. Four sets of slots 48 are opened on the surface of the square frame 41. The locking rods 45 are engaged with the inner wall of the slots 48. A support component 43 is provided between the connector 2 and the square frame 41.

[0024] In this implementation scheme: when connecting the connector 2 to the connector 1, the control component 44 can push the inclined block 47, which drives the locking rod 45 to move. The spring 46 is stressed, and then the connector 2 can be inserted into the connector 1, and the locking rod 45 is inserted into the slot 48. Then, the control component 44 is released, and the spring 46 can drive the locking rod 45 and the inclined block 47 to reset. The locking rod 45 abuts against the inner wall of the slot 48, thus achieving the anti-disengagement function.

[0025] Specifically, the control component 44 includes a slide plate 441, which is slidably connected to the inner wall of the hollow plate 42, and two push blocks 442 are fixedly connected to the lower surface of the slide plate 441.

[0026] In this implementation scheme: Pushing the slide plate 441 can drive the push block 442 to move, and the push block 442 can cooperate with the inclined block 47 to drive the lever 45 to move.

[0027] Specifically, there are multiple springs 46, which are evenly distributed between the latch 45 and the inner wall of the hollow plate 42. The multiple springs 46 can push the latch 45 evenly, and at the same time, the multiple springs 46 can keep the latch 45 stable.

[0028] Specifically, the support component 43 includes six protrusions 433. The six protrusions 433 are fixedly connected to the four sides of the square frame 41 respectively. Two support blocks 431 are fixedly connected to the upper and lower surfaces of the connector 2 respectively. Support blocks 432 are fixedly connected to the other two sides of the connector 2 respectively.

[0029] In this implementation scheme: after the connector 2 is connected to the connector 1, the first support block 431 and the second support block 432 can be attached to the surface of the square frame 41 and the protrusion 433 respectively. When the connector 2 is subjected to a pushing force, the first support block 431 and the second support block 432, together with the square frame 41 and the protrusion 433, can play a supporting and reinforcing role, reducing the situation where the connector 2 is easily deformed by the force, which affects its use.

[0030] Specifically, both support block 1 (431) and support block 2 (432) are arranged in a right-angled trapezoidal shape.

[0031] Specifically, cylindrical rods 435 are fixedly connected to the surfaces of support block 1 431 and support block 2 432 respectively, and a circular hole 434 is opened on the surface of protrusion 433. The cylindrical rod 435 is inserted into the inner wall of the circular hole 434.

[0032] In this embodiment, the cylindrical rods 435 on the surfaces of support block 1 431 and support block 2 432 are inserted into the circular holes 434, which can strengthen support block 1 431 and support block 2 432.

[0033] Working principle: When connecting the connector 2, the sliding plate 441 can be pushed, which in turn moves the push block 442. The push block 442 presses against the inclined block 47, which in turn moves the locking rod 45. The spring 46 is then stressed, and the connector 2 can be inserted into the connector 1. The locking rod 45 is inserted into the slot 48. Then, the control piece 44 is released, and the spring 46 can reset the locking rod 45 and the inclined block 47. The locking rod 45 abuts against the inner wall of the slot 48, achieving an anti-disengagement effect. At the same time, after the connector 2 is connected to the connector 1, the cylindrical rods 435 on the surfaces of the support block 1 431 and support block 2 432 can be inserted into the protrusion. In the circular hole 434 on the surface of block 433, and the support block 1 431 and support block 2 432 are attached to the surface of square frame 41 and protrusion 433. When pushed by external force, support block 1 431 and support block 2 432 can play a supporting and reinforcing role. When it is necessary to pull out the connector 2, simply slide the slide plate 441 towards the side closer to line 3. The slide plate 441 can drive the push block 442 to move. The push block 442 can press on the inclined block 47, so the inclined block 47 can drive the locking rod 45 to move. The spring 46 is under force. At this time, the locking rod 45 loses its restraint on the locking groove 48. With the same force, the connector 2 can be pulled out and the use is completed.
