Description

Technical Field

[0001] This invention relates to the field of data acquisition cards, and in particular to a computer data acquisition card. Background Technology

[0002] Data acquisition refers to the automatic acquisition of non-electrical or electrical signals from analog and digital devices under test, such as sensors and other devices under test, and sending them to a host computer for analysis and processing. A data acquisition card is a computer expansion card that realizes the data acquisition (DAQ) function.

[0003] Most existing data acquisition cards have slots for inserting and connecting data cables. However, since the slots and acquisition cards are mostly fixed in a relatively fixed manner, dust or impurities can easily enter the slots when the data acquisition card is not used for a long time, thus affecting the connection between the slot and the data cable. Summary of the Invention

[0004] The purpose of this invention is to provide a computer data acquisition card that can prevent dust or impurities from easily entering the slot and affecting the connection effect.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A computer data acquisition card includes a card body, a protective cover fixed to one end of the card body, and a connecting block slidably connected to the protective cover. The outer side of the connecting block is provided with multiple insertion holes.

[0007] A horizontal plate is fixed to the upper end of the connecting block, and a spring is provided between the horizontal plate and the card body.

[0008] The lower end of the connecting block has a protruding edge extending outward.

[0009] The data acquisition card is processed using a processing device, which includes a base frame, two support plates connected to the base frame, and two fixed rings fixed to the two support plates respectively. Rotating rings are rotatable inside the two fixed rings, and brackets are fixed inside the two rotating rings. Two clamping plates slide symmetrically on each bracket, and a spring is provided between each clamping plate and the bracket to clamp the two clamping plates on the same bracket.

[0010] Both ends of the clamp are provided with guide ramps.

[0011] Each clamp is provided with a through hole in the middle, and baffles slide in the two through holes on the two clamps on the same bracket.

[0012] The through hole extends outward from the clamp plate and has a groove. A threaded sleeve is fixed in the middle of the outer side of the baffle plate. The threaded sleeve is located in the groove and has an adjusting screw that rotates. The adjusting screw is rotatably connected to the corresponding bracket.

[0013] The base frame has a bidirectional screw that rotates, with its two ends threadedly connected to two support plates respectively.

[0014] Both support plates have rotating transmission sleeves, which are respectively engaged with two rotating rings for transmission. Both transmission sleeves have sliding key shafts inside them.

[0015] One end of the base frame has a worm gear that rotates, and the worm gear is engaged with a worm wheel at one end of the key shaft for transmission. Attached Figure Description

[0032] like Figure 1-4 The following is a detailed description of the computer data acquisition card:

[0033] A computer data acquisition card includes a card body 101, a protective cover 102, and a connecting block 103; the protective cover 102 is fixed to one end of the card body 101, and the connecting block 103 is slidably connected inside the protective cover 102, and the outer side of the connecting block 103 is provided with multiple slots.

[0034] When in use, the data cable is connected through the slot on the connector block 103, and then connected to the PC motherboard. When not in use, the connector block 103 can be slid into the cover 102, so that the cover 102 covers the slot on the connector block 103, thereby preventing dust or impurities from entering the slot and affecting the connection and use of the slot.

[0035] Further:

[0036] The horizontal plate 104 is fixed to the upper end of the connecting block 103, and a spring 105 is provided between the horizontal plate 104 and the card body 101.

[0037] When not in use, the spring force of the spring 105 will push the horizontal plate 104 to drive the connecting block 103 into the protective cover 102, forming automatic protection for the slot without the need for additional pushing.

[0038] When in use, after the connector of the data cable is inserted into the slot, the connector will move into the protective cover 102 along with the connecting block 103, thereby pressing against the protective cover 102 and automatically locking the connecting block 103.

[0039] Further:

[0040] The lower end of the connecting block 103 has a protruding edge 106 extending outward.

[0041] With the protruding edge 106, during use, the connecting block 103 can be slid out from the protective cover 102 by pressing down the protruding edge 106, and then the data cable can be plugged in, which improves the convenience of sliding the connecting block 103 out from the protective cover 102.

[0042] like Figure 1-10 The following is a detailed description of the processing apparatus:

[0043] The data acquisition card is processed using a processing device, which includes a base frame 201, a support plate 301, a fixing ring 302, a rotating ring 304, a bracket 305, a clamping plate 401, and a spring 403. The two support plates 301 are connected to the base frame 201. The two fixing rings 302 are respectively fixed to the two support plates 301. The two rotating rings 304 rotate within the two fixing rings 302. The bracket 305 is fixed within each of the two rotating rings 304. Two clamping plates 401 slide symmetrically on each bracket 305. A spring 403 is provided between each clamping plate 401 and the bracket 305 to clamp the two clamping plates 401 on the same bracket 305.

[0044] The card body 101 is generally manufactured by integrating electronic components such as multiplexers, amplifiers, sample-and-hold circuits, A / D and D / A converters on a circuit board. Therefore, it is necessary to solder the electronic components onto the circuit board. During soldering, the circuit board needs to be fixed. The two ends of the circuit board are inserted between two sets of clamping plates 401. The elastic force of the spring 403 causes the two sets of clamping plates 401 to clamp the two ends of the circuit board, thereby fixing the circuit board. Then, the terminals of the electronic components can be inserted into the corresponding positions on the circuit board and soldered. Furthermore, the two rotating rings 304 can be rotated within the two fixed rings 302 to flip the circuit board, thereby soldering the back of the circuit board, improving the convenience of soldering the circuit board and electronic components.

[0045] Further:

[0046] Both ends of the clamping plate 401 are provided with guide slopes 402.

[0047] By providing guide slopes 402 at both ends of the clamping plate 401, a V-shaped groove is formed at the side ends of the two clamping plates 401. When clamping and fixing the circuit board, the clamping plate 401 can be directly inserted into the V-shaped groove. Guided by the guide slopes 402, the circuit board can be quickly inserted between the two clamping plates 401, forming a clamping of the circuit board end; thus achieving the effect of quickly clamping and fixing the circuit board.

[0048] Further:

[0049] Each clamping plate 401 has a through hole 405 in the middle, and a baffle 501 slides in the two through holes 405 on the two clamping plates 401 on the same bracket 305.

[0050] By setting the baffle 501, when the circuit board is inserted between the two clamping plates 401, the baffle 501 can limit the circuit board, thereby limiting the area of ​​the circuit board clamped by the two clamping plates 401, and preventing the clamping part of the two clamping plates 401 from being too large, which would affect the installation of electronic components.

[0051] Further:

[0052] The through hole 405 extends outward from the clamping plate 401 and has a groove 404. A threaded sleeve 502 is fixed in the middle of the outer side of the baffle 501. The threaded sleeve 502 is located in the groove 404 and has an adjusting screw 503 that rotates with the thread. The adjusting screw 503 is rotatably connected to the corresponding bracket 305.

[0053] By rotating the adjusting screw 503, the threaded sleeve 502 can be moved axially through the threaded drive, which in turn drives the baffle 501 to move axially within the through hole 405. The distance between the baffle 501 and the inner end of the clamping plate 401 is adjusted, thereby forming a limit adjustment of the area of ​​the two clamping plates 401 clamping the circuit board, so that the processing device can adapt to the edge clamping and fixing of different circuit boards.

[0054] Moreover, by sliding the baffle 501 within the through hole 405, the baffle 501 is limited, ensuring that the rotating adjusting screw 503 can drive the threaded sleeve 502 to move axially.

[0055] Meanwhile, the groove 404 provides space for the position of the threaded sleeve 502, thus avoiding affecting the clamping of the clamping plate 401.

[0056] Further:

[0057] The bidirectional screw 202 rotates on the base frame 201, and its two ends are threadedly connected to two support plates 301 respectively.

[0058] By rotating the bidirectional screw 202, the two support plates 301 can be moved closer or further away simultaneously by the threaded drive, thereby adjusting the spacing between the two sets of clamping plates 401, and further enabling the device to be fixed when soldering circuit boards of different sizes.

[0059] like Figure 1-10 As shown:

[0060] Two transmission sleeves 303 rotate on two support plates 301 respectively, and the two transmission sleeves 303 are respectively engaged and connected to two rotating rings 304. A key shaft 203 slides inside each of the two transmission sleeves 303.

[0061] By slidingly connecting the two transmission sleeves 303 with the key shaft 203, the two transmission sleeves 303 rotate synchronously, which in turn causes the two rotating rings 304 to rotate synchronously, thereby keeping the two sets of clamping plates 401 in a parallel state. This makes it easier to align the two sets of clamping plates 401 simultaneously when inserting the circuit board into them, thus improving insertion efficiency.

[0062] Further:

[0063] The worm 204 rotates at one end of the base frame 201, and the worm 204 is engaged with the worm wheel at one end of the key shaft 203 for transmission.

[0064] The self-locking function between the worm gear 204 and the worm wheel on the key shaft 203 locks the rotation of the key shaft 203, preventing the two sets of clamping plates 401 from rotating freely with the two rotating rings 304, thus making it easier to align the circuit board with the two V-grooves for force insertion; further improving insertion efficiency.

[0065] Moreover, it can ensure the stability of the circuit board during soldering, guaranteeing the soldering effect. When the circuit board needs to be flipped, rotating the worm gear 204 adjusts the rotation of the circuit board. Furthermore, it can keep the circuit board at any angle, further facilitating soldering and ensuring the soldering effect.
