Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 As one embodiment of this utility model, a semi-automatic reed switch resistance tester is disclosed. Specifically, the tester includes a test host 2 equipped with a display screen 1 and a base plate 4 equipped with wiring terminals 3. The wiring terminals 3 and the test host 2 are electrically connected. Of course, the test host 2 in this embodiment can be a resistance tester in the prior art. The wiring terminals 3 and the test host 2 can be electrically connected through wires and aviation plugs. This method is a conventional technical means for those skilled in the art and will not be described in detail here.

[0026] A drive unit 5 and a magnetic coil assembly 6 are fixedly installed above the base plate 4. A clamping assembly 7 is provided on the output end of the drive unit 5. The clamping assembly 7 is used to clamp and position the reed switch entering the magnetic coil assembly 6. The magnetic coil assembly 6, the drive unit 5, and the terminal 3 are electrically connected.

[0027] In some embodiments, the driving component 5 in this invention is a cylinder and a solenoid valve mounted on the base plate 4. The cylinder is connected to an external air source through the solenoid valve. The base plate 4 is provided with a switch 51 electrically connected to the solenoid valve. The switch 51 is used to control the circuit conduction of the solenoid valve. For example, when the switch 51 is pressed, the circuit of the solenoid valve is conducted and air is output, and the shaft end of the cylinder extends outward. Of course, the switch 51 can control the solenoid valve by connecting to the input power supply on the terminal block 3. For example, the negative terminal of the terminal block 3 is connected to the negative terminal of the solenoid valve, and the positive terminal of the terminal block 3 is connected to the positive terminal of the solenoid valve through the switch 51. The positive and negative terminals of the terminal block 3 are provided by the test host 2. This control method is a conventional method for those skilled in the art and will not be described in detail here.

[0028] Furthermore, in this embodiment, the magnetic ring assembly 6 includes a magnetic ring seat 61 fixed on the base plate 4. The top of the magnetic ring seat 61 has an insertion port, in which a magnetic ring 62 is fixedly installed. The magnetic ring 62 is electrically connected to the terminal block 3.

[0029] During the specific test, the product is first placed inside the magnetic coil 62. Since the magnetic coil 62 is connected to the test host 2 via wires and terminals 3, the magnetic coil 62 can be powered through the test host 2. After the magnetic coil 62 is powered on, it generates a magnetic field to magnetically attract the contacts inside the reed switch. This keeps the internal circuit of the reed switch product under test conductive, which facilitates the subsequent test of the resistance value.

[0030] Based on the above embodiments, in this embodiment, the magnetic ring seat 61 is slidably connected to a support seat 63 on its side. The support seat 63 is used to support the bottom of the reed switch product. The magnetic ring seat 61 is provided with slide rails 64 through both sides. The back end of the support seat 63 has a slider 65 that slides in the slide rails 64. The slider 65 is locked to the magnetic ring seat 61 by a locking member.

[0031] In one specific embodiment, the locking element described above can be a bolt, i.e., the bolt and the slider 65 are threaded together, and its end abuts against the magnetic ring seat 61. Thus, by turning the bolt, the height position of the support seat 63 can be locked and fixed. The purpose of using this height-adjustable support seat 63 is to ensure that the contact part of the reed switch can be aligned with the magnetic ring 62. If the lead of the reed switch is too short, the position of the support seat 63 can be raised to keep the contact part of the reed switch aligned with the inside of the magnetic ring 62, ensuring the stability of the magnetic attraction operation of the reed switch.

[0032] In some embodiments, the clamping assembly 7 of the present invention includes two fixed shafts 71 fixed on the base plate 4, and clamping arms 72 are rotatably connected to the upper and lower sides of the fixed shafts 71. That is, in this embodiment, a total of four clamping arms 72 are provided. The clamping arms 72 are electrically connected to the terminal block 3 through wires.

[0033] A movable shaft 73 is also slidably mounted on the end face of the base plate 4. The movable shaft 73 is connected to the shaft end of the cylinder. The two clamping arms 72 on the same side cross each other. In this embodiment, "same side" means the same upper side or the same lower side. The two clamping arms 72 on the same side form a clamping structure. The two clamping structures are used to clamp the two ends of the reed switch while maintaining the electrical connection between the two ends of the reed switch. A guide groove 74 is also provided in the middle of the clamping arm 72. The two ends of the movable shaft 73 slide in the guide groove 74 of the two clamping arms 72 on the same side.

[0034] Of course, in order to maintain electrical isolation between the two sets of clamping arms 72, ceramic bearings 75 are sleeved at both ends of the fixed shaft 71 and the movable shaft 73 in this embodiment. The tail end of the clamping arm 72 is sleeved and connected to the ceramic bearing 75 of the fixed shaft 71. The guide groove 74 of the clamping arm 72 and the ceramic bearing 75 of the movable shaft 73 slide in contact. That is, in this embodiment, the ceramic bearings 75 are used to maintain electrical isolation between the upper and lower clamping arms 72. In this way, when the upper and lower clamping arms 72 clamp the two ends of the reed switch, the resistance value of the reed switch can be measured stably.

[0035] Specifically, in this embodiment, a slotted groove 41 is provided at the upper end of the base plate 4, and the end of the movable shaft 73 slides in the slotted groove 41.

[0036] It should be noted that the clamping arm 72 described in this embodiment is made of copper and has an L-shaped structure.

[0037] In the specific testing process, the wires of the solenoid valve and the magnetic coil 62 are first connected to the terminal block 3, and then the terminal block 3 is electrically connected to the test host 2.

[0038] After connection, the carrier 63 is adjusted according to the height of the reed switch product to be tested. After adjustment, the height of the carrier 63 is locked, and the contact part of the reed switch product is kept inside the magnetic ring 62.

[0039] When the magnetic coil 62 is energized, it generates a magnetic field to control the contacts inside the reed switch to close, thus keeping the circuit inside the reed switch conductive. Then, when the switch 51 is pressed, the cylinder shaft drives the movable shaft 73 to extend. The two ends of the movable shaft 73 slide in the guide grooves 74 of the two clamping arms 72 on the same side through the ceramic bearings 75. Since the ends of the clamping arms 72 are restricted by the fixed shaft 71, the two clamping arms 72 on the same side perform clamping movements, thereby clamping both ends of the reed switch.

[0040] Since the clamping arm 72 is electrically connected to the test host 2 via the terminal block 3, after the clamping arm 72 clamps the wire of the reed switch, it simultaneously tests the resistance value of the reed switch and displays it on the display screen 1.

[0041] In summary, during testing, this invention only requires controlling the drive component 5 to move the clamping assembly 7. When the clamping assembly 7 clamps the reed switch, it not only ensures the positional stability of the reed switch, but also, because the clamping assembly 7 is electrically connected to the testing host 2, it can simultaneously complete the resistance detection of the reed switch. The testing operation is simple and convenient. It can quickly test the resistance value of the reed switch, effectively improving testing efficiency.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
