Description

Technical Field

[0001] This invention relates to the field of computer peripheral interface testing, specifically to a computer peripheral interface testing device. Background Technology

[0002] A computer peripheral interface (PII) is a bridge for data exchange and communication between a computer and external devices. It is a logical circuit that connects the computer's CPU and memory to peripheral devices, or between two peripheral devices, or between two machines, via a system bus. It acts as a relay station for information exchange between the CPU and the outside world. The basic functions of a PPI are: first, to select peripheral devices for information transmission; and second, to exchange information between the selected peripheral devices and the host, ensuring that the peripheral devices send or receive information in the form required by the computer system. The interface consists of interface circuitry, connecting cables, and interface software. The PPI acts as a bridge between a microcomputer and peripheral devices, and its main functions include:

[0003] 1. Addressing function: Selects one port from multiple I / O interfaces;

[0004] 2. Data storage and buffering functions;

[0005] 3. Data conversion function;

[0006] 4. Communication function;

[0007] 5. Interrupt management or DMA management functions;

[0008] 6. Command control.

[0009] Among them, the Universal Serial Bus (USB) interface is a brand-new peripheral device interface introduced in recent years. It is a high-speed communication interface with better performance than the standard serial and parallel interfaces used by the system.

[0010] When testing USB interfaces, the frequent plugging and unplugging within a short period causes the interface temperature to rise. Due to thermal expansion and contraction, the USB interface may deform slightly, affecting the test results. Newer USB connectors and interfaces, being less worn, experience greater friction during plugging and unplugging, making connection testing more difficult. Conversely, older USB connectors and interfaces, having undergone more severe wear, experience less friction during plugging and unplugging, making connections unstable and connectors prone to detachment during connection testing.

[0011] Therefore, based on the above problems, we have invented a computer peripheral interface testing device. Summary of the Invention

[0012] In view of the shortcomings of the prior art, the present invention provides a computer peripheral interface testing device to solve the problems mentioned in the background art.

[0015] Furthermore, the upper end of the fixing plate is provided with a smooth inclined surface, which faces away from the bottom of the groove.

[0016] Furthermore, the heat-conducting mechanism includes a transmission groove disposed on the side wall of the rotating ring. An active push plate and a passive push plate are slidably connected in the transmission groove. The transmission groove is provided with through holes that match the active push plate and the passive push plate. The active push plate and the passive push plate are connected by a gear set. A power push plate is installed at the front end of the active push plate. Two fixed plates are installed outside the rotating ring. A fixed shaft is installed between the two fixed plates. A winding roller and a feeding roller are rotatably installed outside the fixed shaft. A main pull wire is fixedly wound on the winding roller. The main pull wire is connected to the rear side of the active push plate. A pulled wire is wound on the feeding roller. The pulled wire is connected to the front side of the passive push plate. A vertical plate is provided on the side of the passive push plate away from the active push plate. The passive push plate and the vertical plate are connected by a buffer telescopic rod. The pulled wire slides through the passive push plate and is connected to the vertical plate. A temperature control mechanism is provided on the vertical plate.

[0017] Furthermore, the gear set includes two drive shafts, both of which are rotatably connected to the inner wall of the drive groove. Both drive shafts are coaxially mounted with drive gears, which mesh with each other. The active push plate and the passive push plate are provided with tooth grooves that mesh with the two drive gears respectively.

[0018] Furthermore, the temperature control mechanism includes a buffer groove on the vertical plate, a buffer block slidably connected in the buffer groove, a stop plate installed at the end of the buffer block away from the buffer groove, a semiconductor cooling chip embedded in the stop plate, the buffer block and the inner wall of the buffer groove being connected by a reset telescopic rod, two metal contact plates installed between the buffer block and the buffer groove, the two metal contact plates being matched and electrically connected to the semiconductor cooling chip, a switching groove provided on the rotating ring, two sets of electrodes installed in the switching groove, the current directions of the two sets of electrodes being opposite, a switching slider slidably installed in the switching groove, the switching slider being matched with the two sets of electrodes, and the two sets of electrodes being electrically connected to the metal contact plates.

[0019] Furthermore, the outer diameter of the winding roller is smaller than the outer diameter of the unwinding roller.

[0020] Furthermore, the clamping mechanism includes two connecting plates, both of which are fixedly installed on the outer wall of the rotating ring. The two connecting plates are fixed together by a U-shaped plate. A clamping plate is slidably installed on the connecting plates.

Two arc-shaped plates are mounted on the U-shaped plate, and the two arc-shaped plates are matched with the upper and lower sides of the synchronous belt respectively.

[0022] Furthermore, the upper end of the abutment is provided with a smooth inclined surface, which faces away from the buffer block.

[0023] Compared with the prior art, the present invention provides a computer peripheral interface testing device, which has the following beneficial effects:

[0024] 1. By setting up a heat conduction mechanism, on the one hand, when the USB connector heats up after repeated plugging and unplugging, the thermoelectric cooler 34 can cool it down, keeping it at room temperature and avoiding affecting the plugging and unplugging test results. On the other hand, when the USB connector is new and difficult to plug and unplug with the computer peripheral interface, the thermoelectric cooler 34 cools the USB connector. Under the effect of thermal expansion and contraction, the size of the USB connector is slightly reduced, making it easier to plug into the computer peripheral interface. When the USB connector is worn, the switching slider 37 is pushed, connecting the switching slider 37 to another set of electrodes 36. At this time, the current direction of the thermoelectric cooler 34 is changed. The part of the thermoelectric cooler 34 that contacts the USB connector heats up the USB connector. Under the effect of thermal expansion and contraction, the USB connector expands, and its size increases slightly, making it more stable when plugged into the computer peripheral interface and preventing it from falling off. At the same time, when the USB connector is plugged and unplugged from the computer peripheral interface, the thermoelectric cooler 34 can automatically separate and contact the USB connector, regulating and controlling the temperature of the USB connector for subsequent testing.

[0025] 2. By setting up a clamping mechanism and a stop mechanism, the clamping position of the USB connector can be adjusted when clamping the USB connector, so that the USB connector is in a suitable position, which facilitates the insertion and testing of computer peripheral interfaces.

[0026] This application provides good clamping effect for USB connectors, allows for temperature adjustment of USB connectors, and provides good results for plug-in testing of computer peripheral interfaces. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a computer peripheral interface testing device.

[0038] like Figures 1-8 As shown, a computer peripheral interface testing device includes a rotating ring 1, a fixed ring 2 rotatably sleeved on the outside of the rotating ring 1, a motor 46 mounted on the fixed ring 2, a drive shaft of the motor 46 rotatably passing through the fixed ring 2 and a drive gear 47 coaxially mounted thereon, an annular toothed groove matching the drive gear 47 provided on the outer wall of the rotating ring 1, a camera mounted on the fixed ring 2 matching the motor 46, a placement groove 3 provided inside the rotating ring 1, a clamping mechanism 4 for clamping a USB connector provided inside the placement groove 3, a heat conduction mechanism 5 for conducting heat to the USB connector provided on the rotating ring 1, and a clamping mechanism 7 for clamping the USB connector provided on the rear side of the rotating ring 1.

[0039] In this invention, the clamping mechanism 4 includes a groove 8 set on the inner wall of the placement groove 3. A limiting rod 10 is fixedly installed in the groove 8. Two limiting sliders 11 are slidably sleeved on the limiting rod 10. Two buffer springs 12 are sleeved on the limiting rod 10. The two ends of the two buffer springs 12 are fixedly installed to the limiting sliders 11 and the inner wall of the groove 8, respectively. A fixed clamping plate 9 is slidably installed in the groove 8. A deflection rod 13 is rotatably installed on each of the two limiting sliders 11. The end of the deflection rod 13 away from the limiting slider 11 is rotatably connected to the fixed clamping plate 9. It is worth mentioning that the upper end of the fixed clamping plate 9 is provided with a smooth inclined surface, which faces away from the bottom of the groove 8.

[0040] Through the above technical features: when the USB connector is placed in the placement slot 3, the plastic part of the USB connector will open the fixing plate 9. The fixing plate 9 clamps the USB connector under the action of the buffer spring 12. At the same time, the abutment 31 abuts against the metal part of the USB connector, making it more convenient to clamp the USB interface.

[0041] In this invention, the heat-conducting mechanism 5 includes a transmission groove 14 disposed on the side wall of the rotating ring 1. An active push plate 15 and a passive push plate 16 are slidably connected within the transmission groove 14. The transmission groove 14 has through holes 17 that match the active push plate 15 and the passive push plate 16. The active push plate 15 and the passive push plate 16 are connected by a gear set 18. It should be noted that the gear set 18 includes two transmission shafts 19, both of which are rotatably connected to the inner wall of the transmission groove 14. Transmission gears 20 are coaxially mounted on the outside of each of the two transmission shafts 19, and the two transmission gears 20 are meshed together. The active push plate 15 and the passive push plate 16 have toothed grooves that mesh with the two transmission gears 20 respectively. A power push plate 49 is mounted at the front end of the active push plate 15. Two [unclear - possibly referring to a specific type of plate] are mounted outside the rotating ring 1. A fixed plate 21 is provided, and a fixed shaft 22 is installed between the two fixed plates 21. It should be noted that the fixed shaft 22 is installed to the fixed plate 21 by a spiral spring. A winding roller 23 and a feeding roller 24 are rotatably installed on the fixed shaft 22. It should be noted that the outer diameter of the winding roller 23 is smaller than the outer diameter of the feeding roller 24. A main pull line 25 is fixedly wound on the winding roller 23. The main pull line 25 is connected to the rear side of the active push plate 15. A pulled line 26 is wound on the feeding roller 24. The pulled line 26 is connected to the front side of the passive push plate 16. A vertical plate 27 is provided on the side of the passive push plate 16 away from the active push plate 15. The passive push plate 16 and the vertical plate 27 are connected by a buffer telescopic rod 28. The pulled line 26 slides through the passive push plate 16 and is connected to the vertical plate 27. A temperature control mechanism 6 is provided on the vertical plate 27.

[0042] In this invention, the temperature control mechanism 6 includes a buffer groove 29 disposed on a vertical plate 27, a buffer block 30 slidably connected in the buffer groove 29, a stop plate 31 installed at the end of the buffer block 30 away from the buffer groove 29, a semiconductor cooling chip 34 embedded in the stop plate 31, the buffer block 30 and the inner wall of the buffer groove 29 being connected by a reset telescopic rod 32, two metal contact pieces 33 being installed between the buffer block 30 and the buffer groove 29, the two metal contact pieces 33 being matched, and both metal contact pieces 33 being electrically connected to the semiconductor cooling chip 34, a switching groove 35 disposed on the rotating ring 1, two sets of electrodes 36 being installed in the switching groove 35, the current directions of the two sets of electrodes 36 being opposite, a switching slider 37 being slidably installed in the switching groove 35, the switching slider 37 being matched with the two sets of electrodes 36, and both sets of electrodes 36 being electrically connected to the metal contact pieces 33.

[0043] It should be noted that a thermoelectric cooler, also called a semiconductor refrigeration chip, is a type of heat pump. Its advantage is the absence of moving parts, making it suitable for applications where space is limited, reliability is critical, and refrigerant contamination is undesirable. Utilizing the Peltier effect of semiconductor materials, when direct current passes through a coupler composed of two different semiconductor materials connected in series, heat is absorbed and released at the two ends of the coupler, achieving cooling. It is a cooling technology that generates negative thermal resistance, characterized by the absence of moving parts and relatively high reliability. Its working principle is as follows:

[0044] like Figure 8 As shown, when an N-type semiconductor material and a P-type semiconductor material are connected to form an electrical couple, energy transfer occurs when a direct current is applied to this circuit. The current flows from the N-type element to the P-type element, absorbing heat at the junction, which becomes the cold end, and from the P-type element to the N-type element, releasing heat at the junction, which becomes the hot end. The magnitude of heat absorption and release is determined by the magnitude of the current and the number of element pairs in the N and P semiconductor materials. The thermoelectric stack inside the cooling chip consists of hundreds of electrical couples to enhance the cooling (heating) effect.

[0045] Where Qc: heat absorbed at the condenser, T: condenser temperature, Qh: heat released, Th: temperature at the heat-releasing end, V: voltage, p: current, n: current, Qj: Joule heat, Qk: cooling capacity.

[0046] It should be noted that when the direction of the current is opposite, the cooling direction of the thermoelectric cooler is correspondingly reversed.

[0047] Through the above technical features, when the USB interface is plugged into the computer peripheral interface, the power push plate 49 abuts against the computer casing and pushes the power push plate 49 to move in the opposite direction. The power push plate 49 drives the active push plate 15 to move. The active push plate 15 drives the passive push plate 16 to move through two transmission gears 20. The passive push plate 16 drives the vertical plate 27 to move through the buffer telescopic rod 28. At the same time, the active push plate 15 pulls the main pull cable 25 during its movement. The main pull cable 25 drives the winding roller 23 to rotate. The winding roller 23 drives the unwinding roller 24 to rotate through the fixed shaft 22. The unwinding roller 24 winds the pulled cable 26. The pulled cable 26 pulls the vertical plate 27 to move, causing the vertical plate 27 to separate from the metal part of the USB connector until the USB connector is connected to the computer peripheral interface. When the USB connector is pulled out of the computer peripheral interface, the fixed shaft 22 returns to its original position under the action of the spiral spring. At this time, the power push plate 49 and the abutment plate 31 return to their original positions. At this time, the abutment plate 31 and the metal part of the USB connector are separated. The two metal contact pieces 33 make partial contact, abutting each other to connect the power supply to the thermoelectric cooler 34. On the one hand, when the USB connector heats up after repeated plugging and unplugging, the thermoelectric cooler 34 can cool it down to keep it at room temperature, avoiding affecting the plugging and unplugging test results. On the other hand, when the USB connector is new and difficult to plug and unplug into the computer peripheral interface, the thermoelectric cooler 34 cools the USB connector. Under the effect of thermal expansion and contraction, the size of the USB connector is slightly reduced, making it easier to plug into the computer peripheral interface. When the USB connector is worn, the switching slider 37 is pushed, connecting the switching slider 37 to another set of electrodes 36. At this time, the current direction of the thermoelectric cooler 34 is changed. The contact part between the thermoelectric cooler 34 and the USB connector heats the USB connector. Under the effect of thermal expansion and contraction, the USB connector expands, and the size of the USB connector increases slightly, making it more stable when plugged into the computer peripheral interface and preventing it from falling off.

[0048] In this invention, the clamping mechanism 7 includes two connecting plates 38, both of which are fixedly installed on the outer wall of the rotating ring 1. The two connecting plates 38 are fixed together by a U-shaped plate 39. A clamping plate 40 is slidably installed on the connecting plates 38. A pushing screw 41 is fixedly installed on one end of the clamping plate 40. A transmission sleeve 48 is threaded onto the external thread of the pushing screw 41. The transmission sleeve 48 is rotatably inserted through the U-shaped plate 39. The two transmission sleeves 48 are connected by a transmission mechanism 43. Furthermore, the transmission mechanism 43 includes two pulleys 44, which are coaxially installed with the two transmission sleeves 48 respectively. The two pulleys 44 are connected by a synchronous belt. Two arc-shaped plates 45 are installed on the U-shaped plate 39. The two arc-shaped plates 45 are matched with the upper and lower sides of the synchronous belt respectively. A handle 42 is fixedly installed on one end of one of the transmission sleeves 48.

[0049] Through the above technical features: by rotating the handle 42, the handle 42 drives the two transmission sleeves 48 to rotate, the transmission sleeves 48 drive the push screw 41 to move, the push screw 41 drives the clamping plate 40 to move, and the clamping plate 40 drives the USB connector to move until the appropriate position is reached, the clamping position of the USB connector can be adjusted. At the same time, the clamping plate 40 can provide support force when the USB connector is plugged in and unplugged, so as to prevent the USB connector from slipping during plugging and unplugging, resulting in poor plugging and unplugging effect.

[0050] Working principle:

[0051] 1) Fixing and securing the USB connector: Place the USB connector in the placement slot 3. The plastic part of the USB connector will open the fixing plate 9. The fixing plate 9 clamps the USB connector under the action of the buffer spring 12. At the same time, the abutment plate 31 abuts against the metal part of the USB connector. By rotating the handle 42, the handle 42 drives the two transmission sleeves 48 to rotate. The transmission sleeves 48 drive the push screw 41 to move. The push screw 41 drives the abutment plate 40 to move. The abutment plate 40 drives the USB connector to move until it is in the appropriate position.

[0052] 2) USB connector connection to computer peripheral interface: When the USB connector is plugged into the computer peripheral interface, the power push plate 49 abuts against the computer casing and pushes the power push plate 49 to move in the opposite direction. The power push plate 49 drives the active push plate 15 to move. The active push plate 15 drives the passive push plate 16 to move through two transmission gears 20. The passive push plate 16 drives the vertical plate 27 to move through the buffer telescopic rod 28. At the same time, the active push plate 15 pulls the main pull cable 25 during its movement. The main pull cable 25 drives the winding roller 23 to rotate. The winding roller 23 drives the unwinding roller 24 to rotate through the fixed shaft 22. The unwinding roller 24 winds the pulled cable 26. The pulled cable 26 pulls the vertical plate 27 to move, causing the vertical plate 27 to separate from the metal part of the USB connector until the USB connector is connected to the computer peripheral interface. When the USB connector is pulled out of the computer peripheral interface, the fixed shaft 22 returns to its original position under the action of the spiral spring. At this time, the power push plate 49 and the abutment plate 31 return to their original positions. The metal part of the USB connector is in contact with the electrode 31, and the two metal contact pieces 33 abut against each other, connecting the power supply to the thermoelectric cooler 34. On the one hand, when the USB connector heats up after repeated plugging and unplugging, the thermoelectric cooler 34 can cool it down to keep it at room temperature, avoiding affecting the plugging and unplugging test results. On the other hand, when the USB connector is new and difficult to plug and unplug with the computer peripheral interface, the thermoelectric cooler 34 cools the USB connector. Under the effect of thermal expansion and contraction, the size of the USB connector is slightly reduced, making it easier to plug into the computer peripheral interface. When the USB connector is worn, the switching slider 37 is pushed, connecting the switching slider 37 to another set of electrodes 36. At this time, the current direction of the thermoelectric cooler 34 is changed. The part of the thermoelectric cooler 34 that is in contact with the USB connector heats up the USB connector. Under the effect of thermal expansion and contraction, the USB connector expands, and the size of the USB connector increases slightly, making it more stable when plugged into the computer peripheral interface.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.
