Description

Technical Field

[0001] This utility model relates to the field of circuit testing technology, specifically to a circuit testing fixture that is easy to adjust. Background Technology

[0002] Circuit testing is a crucial step in ensuring the correctness, reliability, and performance of circuit designs, and it is integral to the entire process of circuit design, manufacturing, and use. This includes: functional testing: verifying whether the circuit performs its intended function as designed; performance testing: evaluating the circuit's electrical characteristics, such as voltage, current, and frequency response; reliability testing: testing the circuit's performance under extreme conditions, such as high temperature, low temperature, and high humidity; and safety testing: checking whether the circuit meets safety standards, such as insulation testing and leakage current testing.

[0003] A search of existing technology reveals that publication number CN108051618A discloses a tooling fixture for circuit board testing. The fixture comprises a first support, a second support, spring test pins, a spring, and fastening screws. The second support has a connecting block and a first spring groove, while the first support has a limiting groove corresponding to the connecting block. The connecting block extends into the limiting groove and is connected to the first support via fastening screws. One end of the first support has a second spring groove, with the spring positioned between the first and second spring grooves. The other end of the first support has multiple spring test pin through holes into which spring test pins are inserted. In the non-working state, the spring test pin tips contact the second support; in the working state, the spring is compressed, and circuit board pads are placed between the spring test pin tips and the second support.

[0004] The prior art document utilizes the lever principle and spring deformation, along with the deformation of the spring test pin, to generate elastic force, ensuring the fixture reliably clamps onto the solder pads. However, it lacks adjustable fixture limits and provides insufficient protection for the testing device, making it susceptible to damage. Utility Model Content

[0005] The purpose of this invention is to provide an easily adjustable circuit testing fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Preferably, it includes two fixing bars that are rotatably connected to each other. One end of each fixing bar is provided with a support spring, and a limiting mechanism is provided inside the support spring. One end of one fixing bar away from the limiting mechanism is provided with a detection device. A fixing plate is provided on one side of the detection device, and a limiting device is provided on the fixing plate. The limiting device is adapted to the detection device.

[0008] Preferably, one end of the fixing strip has a through hole, a limiting groove is formed in the through hole, a fixing base is slidably connected in the through hole, a positioning strip is provided on the fixing base, a groove is provided in the middle of the side of the fixing base, a connecting thread is provided in the groove, the positioning strip is adapted to the limiting groove, a rotating groove is formed in the through hole, a rotating disk is provided in the rotating groove, and the rotating disk is threadedly connected to the fixing base.

[0009] Preferably, a fixing ring is provided on one side of the two fixed bases that are close to each other, a limiting chain is provided between the fixing rings, and a supporting spring is provided on the outside of the limiting chain.

[0010] Preferably, one side of the fixing strip is provided with an adjustment groove, and one side of the rotating disk extends out from the adjustment disk.

[0011] Preferably, the detection device includes a probe, the probe having a hollow interior, a telescopic rod inside the probe, a contact point at the lower end of the telescopic rod, a cylindrical rod at the upper end of the probe, a supporting spring inside the cylindrical rod, and a connection interface on one side of the probe, the connection interface being connected to the probe.

[0012] Preferably, the limiting device includes a rotating rod, a limiting strip is provided on one side of the rotating rod, and a plurality of arc-shaped grooves are provided on the limiting strip, the arc-shaped grooves being adapted to the telescopic rod.

[0013] Compared with existing technologies, the advantages of this invention are: it can limit the angle of the two fixing strips by adjusting the rotating disk, adapting to circuit detection targets of different sizes, while providing good protection for the detection device and preventing damage. When it is necessary to adjust the included angle of the fixing strips, adjusting the rotating disk, which is threadedly connected to the fixed base, will drive the fixed base to move in the vertical direction. When the fixed base is driven by the rotating disk, the positioning strip of the fixed base is fixed in the limiting groove, preventing the fixed base from rotating with it. When the position of the fixed base relative to the positioning strip changes, it can limit the angle change between the two positioning bases and the positioning strip. When not performing detection, rotating the rotating rod will fix and protect the telescopic rod with the limiting strip on the rotating rod, protecting the telescopic rod from damage.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 The embodiments provided by this utility model are as follows:

[0021] Example: Includes two fixing bars 1, which are rotatably connected. One end of each fixing bar 1 is provided with a support spring 2, and a limiting mechanism 3 is provided inside the support spring 2. One end of one fixing bar 1 away from the limiting mechanism 3 is provided with a detection device 4. A fixing plate 5 is provided on one side of the detection device 4, and a limiting device 6 is provided on the fixing plate 5. The limiting device 6 is adapted to the detection device 4.

[0022] One section of the fixing strip 1 has a through hole 7, and a limiting groove 8 is formed in the through hole 7. A fixing base 9 is slidably connected within the through hole 7. The fixing base 9 has a positioning strip 10, and a groove 11 is formed in the middle of its side. The groove 11 has a connecting thread. The groove 11 can limit the movement range of the positioning base and prevent the positioning base from falling out. The positioning strip 10 is adapted to the limiting groove 8. A rotating groove is formed in the through hole 7, and a rotating disk 12 is formed in the rotating groove. The rotating disk 12 is threadedly connected to the fixing base 9. The rotating disk 12 can adjust the position of the positioning base.

[0023] A fixing ring 13 is provided on one side of the two fixed bases 9 that are close to each other. A limiting chain 14 is provided between the fixing rings 13, and a support spring 2 is provided on the outside of the limiting chain 14. The limiting chain 14 can connect and limit the two fixed bases 9, thereby limiting the angle of the positioning strip 10.

[0024] An adjustment groove is provided on one side of the fixing strip 1, and one side of the rotating disk 12 extends out from the adjustment disk. The extended rotating disk 12 is easy to adjust and drives itself to rotate.

[0025] The detection device 4 includes a probe 15, which has a hollow interior and a telescopic rod 16 inside. The lower end of the telescopic rod 16 has a contact point 17, and the upper end of the probe 15 has a cylindrical rod with a supporting spring 2 inside. One side of the probe 15 has a connection interface that is connected to the probe 15.

[0026] The limiting device 6 includes a rotating rod 18, and a limiting strip 19 is provided on one side of the rotating rod 18. The limiting strip 19 has multiple arc-shaped grooves, which are adapted to the telescopic rod 16.

[0027] When circuit testing is required, pressing the section of the fixing strip 1 near the fixing base 9 opens the end of the fixing strip 1 equipped with the testing device 4. This allows the testing device 4 to connect to the circuit to be tested, and a cable can be inserted into the connection interface for circuit testing. When adjusting the angle of the fixing strip 1, adjusting the rotating disk 12, which is threadedly connected to the fixing base 9, will cause the fixing base 9 to move vertically. When the fixing base 9 is driven by the rotating disk 12, the positioning strip 10 of the fixing base 9 is fixed in the limiting groove 8, preventing the fixing base 9 from rotating. When the position of the fixing base 9 relative to the positioning strip 10 changes, the angle between the two positioning bases and the positioning strip 10 changes. When not testing, rotating the rotating rod 18 fixes and protects the telescopic rod 16 with the limiting strip 19 on the rotating rod 18, preventing damage to the telescopic rod 16.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
