Description

Technical Field

[0001] The present invention belongs to the technical field of USB flash drives, and specifically relates to an integrated package storage module with one male and one female dual USB interfaces. Background Art

[0002] A USB flash drive is short for USB (universal serial bus) drive, and is also called a "thumb drive" according to its homophone. A USB flash drive is a type of flash memory, so it is sometimes also called a flash drive. The biggest difference between a USB flash drive and a hard disk is that it does not require a physical drive, is plug-and-play, and its storage capacity far exceeds that of a floppy disk, making it extremely convenient to carry. A USB flash drive integrates disk storage technology, flash memory technology, and universal serial bus technology. The USB port is connected to the computer and is the channel for data input / output; the main control chip enables the computer to recognize the USB flash drive as a removable disk and is the "brain" of the USB flash drive; the USB flash drive's Flash (flash memory) chip stores data. Different from the computer's memory, the data will not be lost even after power-off; the PCB board connects all components together and provides a platform for data processing.

[0003] The existing USB flash drives only have a storage function and cannot be charged through the USB flash drive. For example, when a music USB flash drive is plugged into the USB interface on a car stereo, it cannot be charged through the USB interface, which is inconvenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated package storage module with one male and one female dual USB interfaces to solve the problem that the existing USB flash drives only have a storage function and cannot be charged through the USB flash drive. For example, when a music USB flash drive is plugged into the USB interface on a car stereo, it cannot be charged through the USB interface, which is inconvenient to use.

When the connection hole moves to the position of the second locking block, the third spring makes the second locking block move upward into the connection hole through its elastic force to fix the connection block. The pin is inserted into the connection plate through the first fixing groove. When the pin moves to the left, it squeezes the first locking block, causing the first locking block to move to the right. When the pin fixing groove moves to the position of the first locking block, the first locking block moves to the left through the elastic force of the second spring, enabling the first locking block to enter the pin fixing groove, thus fixedly connecting the connection block and the connection plate. When the USB connector is connected to the USB female connector, the outer wall of the USB connector is fixed by the fixing spring piece, making the internal connection of the module more stable.

[0018] 3. In the present invention, when the USB connector enters the USB female connector, it squeezes the connection terminal, causing the connection terminal to move inward. Through the elastic force of the first spring, a thrust is given to the connection terminal to move outward, making the connection between the USB connector and the USB female connector tighter.

[0028] Refer to Figure 1-7, a dual USB interface integrated package storage module with one male and one female, including a USB female head connector 1 and a USB male head connector 2. The USB female head connector 1 and the USB male head connector 2 are integrally packaged. The USB male head connector 2 is in a "concave" shape structure. Connection grooves 3 are opened on the outer walls on both the left and right sides of the USB female head connector 1. Fixed elastic pieces 4 are fixedly connected inside the connection grooves 3. A connecting plate 6 is fixedly connected inside the USB female head connector 1. The USB male head connector 2 is divided into a USB male head upper surface 201 and a USB male head lower surface 202. Gold fingers 5 are fixedly connected to the outer wall of the USB male head upper surface 201, and charging terminals 7 are fixedly connected to the outer wall of the USB male head lower surface 202. The gold fingers 5 and the charging terminals 7 share VCC and GND. A number of terminal grooves 8 are opened on the outer wall of the connecting plate 6. First springs 9 are fixedly connected inside the terminal grooves 8. One end of the first spring 9 far from the terminal groove 8 is fixedly connected with a connecting terminal 10. The number of connecting terminals 10 is four, corresponding to DM, DP, GND, and VCC respectively, and the arrangement is VCC, DM, DP, GND. And DM and DP are differential signals. A first fixing groove 11 is opened at the bottom of the connecting plate 6, and a first locking groove 12 is opened on the right side of the first fixing groove 11. A second spring 13 is fixedly connected inside the first locking groove 12. A first locking block 14 is fixedly connected to the left side of the second spring 13. The left side of the first locking block 14 and the top of the connecting terminal 10 are both in a bevel structure. A second fixing groove 15 is opened on the left outer wall of the USB male head connector 2, and a second locking groove 16 is opened at the bottom of the second fixing groove 15. A third spring 17 is fixedly connected inside the second locking groove 16. A second locking block 18 is fixedly connected to the top of the third spring 17. A connecting block 19 is clamped inside the second fixing groove 15. When the connecting block 19 moves inward, the second locking block 18 is squeezed by the connecting block 19 and moves downward. When the connection hole 20 moves to the position of the second locking block 18, the third spring 17 makes the second locking block 18 move upward into the connection hole 20 through its rebounding force to fix the connecting block 19. A connection hole 20 is opened on the upper surface of the connecting block 19. The USB male head connector 2 is fixedly connected with the connecting block 19 by inserting the second locking block 18 into the connection hole 20. A number of pins 21 are fixedly connected to the left side of the connecting block 19. Pin fixing grooves 22 are opened on the outer walls of the pins 21. The connecting plate 6 is fixedly connected with the connecting block 19 by inserting the first locking block 14 into the pin fixing grooves 22. The pins 21 are inserted into the connecting plate 6 through the first fixing groove 11. When the pins 21 move to the left, the first locking block 14 is squeezed, making the first locking block 14 move to the right. When the pin fixing groove 22 moves to the position of the first locking block 14, the first locking block 14 moves to the left through the rebounding force of the second spring 13, making the first locking block 14 enter the pin fixing groove 22, so that the connecting block 19 and the connecting plate 6 are fixedly connected. When the USB connector is connected to the USB female head connector 1, the outer wall of the USB connector is fixed by the fixed elastic piece 4.Meanwhile, when the USB connector enters the USB female connector 1, it presses the connection terminal 10, causing the connection terminal 10 to move inward. Through the resilience of the first spring 9, a thrust force for the connection terminal 10 to move outward is given, making the connection between the USB connector and the USB female connector 1 tighter. Inside the USB male connector 2, there is a fixed insulating partition 23. At the top of the insulating partition 23, there is a fixed FLASH chip 24. The top of the FLASH chip 24 is in contact with the bottom of the gold finger 5. At the bottom of the insulating partition 23, there is a coupler 25. The bottom of the coupler 25 is in contact with the top of the charging terminal 7. When the USB male connector 2 is inserted into the USB interface, the data in the FLASH chip 24 is transmitted through the gold finger 5. At the same time, the charging terminal 7 is connected to the coupler block 25, and the coupler block 25 transmits the current to the USB connector through the connection terminal 10, enabling both data transmission and charging. By setting the insulating partition 23, the FLASH chip 24 and the coupler block 25 are separated to prevent the circuits from mixing together.

[0029] Working principle: Insert the connection block 19 into the second fixing groove 15. When the connection block 19 moves inward, the second locking block 18 is pressed by the connection block 19 and moves downward. When the connection hole 20 moves to the position of the second locking block 18, the third spring 17 makes the second locking block 18 move upward through its resilience and enter the connection hole 20 to fix the connection block 19. Insert the pin 21 into the connection plate 6 through the first fixing groove 11. When the pin 21 moves to the left, it presses the first locking block 14, causing the first locking block 14 to move to the right. When the pin fixing groove 22 moves to the position of the first locking block 14, the first locking block 14 moves to the left through the resilience of the second spring 13, and the first locking block 14 enters the pin fixing groove 22, making the connection block 19 and the connection plate 6 fixedly connected. When the USB connector is connected to the USB female connector 1, the outer wall of the USB connector is fixed by the fixing spring piece 4. Meanwhile, when the USB connector enters the USB female connector 1, it presses the connection terminal 10, causing the connection terminal 10 to move inward. Through the resilience of the first spring 9, a thrust force for the connection terminal 10 to move outward is given, making the connection between the USB connector and the USB female connector 1 tighter. When the USB male connector 2 is inserted into the USB interface, the data in the FLASH chip 24 is transmitted through the gold finger 5. At the same time, the charging terminal 7 is connected to the coupler block 25, and the coupler block 25 transmits the current to the USB connector through the connection terminal 10, enabling both data transmission and charging. By setting the insulating partition 23, the FLASH chip 24 and the coupler block 25 are separated to prevent the circuits from mixing together.
