It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0030] SMT (Surface Mount Technology) is a circuit assembly technology that mounts leadless or short-lead surface-mount electronic components onto the surface of a printed circuit board or other substrate, and then solders them using methods such as reflow soldering or dip soldering. Before mounting, the electronic components usually need to be tested. When using traditional probes to obtain the electrical parameters of the electronic components, multiple testing front-ends are often required, which necessitates manual operation, making the process difficult and inefficient.

[0031] To alleviate or solve the above technical problems, this utility model proposes a self-holding probe fixture for electronic devices, including a probe body 30, a clamping assembly 10, and a base assembly 20. The two clamping arms 11 of the clamping assembly 10 can clamp the electronic device and are electrically connected to its two pins. The two clamping arms 11 are respectively connected to the probe body 30 and a grounding component, thereby enabling parameter testing of the electronic device. Since the two clamping arms 11 of the clamping assembly 10 can clamp the electronic device and are connected to it, the electronic device can be tested while clamped. This solves the problem of existing test probes requiring additional grounding operations and introduces less loop interference. Furthermore, it eliminates the need for manual operation during testing, making testing more convenient, efficient, and accurate.

[0032] The self-holding probe fixture for electronic devices provided in this embodiment of the present invention will now be described. The self-holding probe fixture is used to hold electronic devices and is electrically connected to the electronic devices for performing electrical tests. The electronic devices can be capacitors, resistors, inductors, etc.

[0033] Please see Figure 1 and Figure 2 The self-holding probe fixture for electronic devices includes:

[0034] The probe body 30 is used for electrical connection with the testing equipment;

[0035] The clamping assembly 10 includes a clamping base 13, two clamping arms 11, and an elastic element 12. Both clamping arms 11 are rotatably connected to the clamping base 13. The two ends of the elastic element 12 are respectively connected to the two clamping arms 11. The two clamping arms 11 are used to clamp electronic devices and respectively for contacting and conducting with two pins of the electronic devices. The probe body 30 is electrically connected to one of the clamping arms 11, and the other clamping arm 11 is grounded.

[0036] The base assembly 20 is used to support the clamping assembly 10, and the clamping seat 13 is connected to the base assembly 20.

[0037] One end of the probe body 30 is electrically connected to the test equipment for outputting a detection signal, while the other end is used to conduct electricity with an electronic device. When the probe body 30 and the electronic device are connected and a circuit is formed, electrical testing of the electronic device can be performed. For example, the test equipment is an oscilloscope, and the probe body 30 is an oscilloscope probe.

[0038] The clamping assembly 10 is used to clamp electronic devices and is electrically connected to them. The clamping assembly 10 includes a clamping base 13, two clamping arms 11, and an elastic element 12. The clamping base 13 is the main structure of the clamping assembly 10. The clamping base 13 is used to mount the two clamping arms 11, which are rotatable relative to the clamping base 13, allowing the distance between the ends of the two clamping arms 11 to increase or decrease. The elastic element 12 is connected to the two clamping arms 11 at both ends, providing a restoring force for the rotation of the clamping arms 11 relative to the clamping base 13, and also providing a clamping force to clamp the electronic devices, thus clamping the electronic devices between the two clamping arms 11. Simultaneously, at least part of the clamping arms 11 are made of conductive material, with one clamping arm 11 electrically connected to the probe body 30 and the other clamping arm 11 electrically connected to a grounding component. When the two clamping arms 11 clamp the electronic device, the two pins of the electronic device are also electrically connected to the two clamping arms 11 respectively, thereby forming a complete detection circuit to perform electrical detection on the clamped electronic device.

[0039] The base assembly 20 supports the clamping assembly 10. The clamping seat 13 of the clamping assembly 10 is connected to the base assembly 20, allowing the clamping assembly 10 to be mounted on the base assembly 20 and thus suspended in the air. The base assembly 20 can be placed on a desktop, tabletop, floor, or other surface. When the clamping assembly 10 clamps electronic devices, the electronic devices, probe body 30, etc., are kept at a certain distance from the surface, preventing contact between the surface and the electronic devices, probe body 30, etc. This maintains the stability of the connection between the electronic devices and the clamping arm 11, thereby ensuring the accuracy of the electrical testing results.

[0040] The self-holding probe fixture for electronic devices in the above embodiments includes a probe body 30, a clamping assembly 10, and a base assembly 20. The probe body 30 is used to connect the test equipment and the electronic device to perform testing on the electronic device to obtain electrical parameters. The two clamping arms 11 of the clamping assembly 10 clamp the electronic device, and the two clamping arms 11 respectively contact and connect with the two pins of the electronic device. In this way, the two pins of the electronic device can be connected to the probe body 30 and the grounding component respectively, without occupying both hands for operation. This can reduce the difficulty of operation and improve the testing efficiency of electronic devices.

[0041] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The clamping base 13 has multiple adjustment holes 132, and the clamping arms 11 can be selectively installed in different adjustment holes 132. The clamping arms 11 are installed on the clamping base 13 through the adjustment holes 132 on the clamping base 13. The positions of the different adjustment holes 132 are different. When the clamping arms 11 are installed in different adjustment holes 132, the position of the clamping arms 11 changes accordingly. This allows the distance and relative position between the two clamping arms 11 to be adjusted, making the clamping assembly 10 suitable for electronic devices of different specifications and sizes.

[0042] By designing multiple adjustment holes 132 on the clamping base 13, the clamping arms 11 can be installed at different adjustment holes 132, thereby changing the distance between the two clamping arms 11 in the initial state (the state without external force). Users can adjust the position of the clamping arms 11 according to their needs, making it suitable for electronic devices of different specifications and types.

[0043] In some embodiments, multiple adjustment holes 132 can be used to adjust one clamping arm 11, that is, one clamping arm 11 is fixed, while the other clamping arm 11 can be installed in a different adjustment hole 132. In this way, by adjusting the position of one clamping arm 11, the distance between the two clamping arms 11 in the initial state can be adjusted.

[0044] In some embodiments, the multiple adjustment holes 132 can be used to adjust the two clamping arms 11. That is, the two clamping arms 11 can be installed in different adjustment holes 132, and the positions of the two clamping arms 11 can be adjusted. In this way, the positions of the two clamping arms 11 can be adjusted simultaneously during use, so that the adjustment space of the clamping assembly 10 is larger and it can be used for more specifications and types of electronic devices.

[0045] In some embodiments, a plurality of adjustment holes 132 are distributed sequentially at intervals along a straight line. In this embodiment, the center distance between two adjacent adjustment holes 132 is relatively large, which can be applied to electronic devices of different specifications with large size differences.

[0046] In some embodiments, a plurality of adjustment holes 132 are sequentially and continuously distributed along a straight line. Understandably, in this embodiment, two adjacent adjustment holes 132 are interconnected, and the connection point is called a connecting channel. The width of the connecting channel is smaller than the diameter of the adjustment hole 132. In this way, the center distance between two adjacent adjustment holes 132 can be smaller, and the position adjustment accuracy of the clamping arm 11 can be higher.

[0047] In some embodiments, the plurality of adjustment holes 132 are distributed at intervals or in succession along the circumferential direction.

[0048] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The clamping base 13 and the clamping arm 11 are rotatably connected by a hinge pin 14. The clamping arm 11 has a mounting hole 1118. The hinge pin 14 passes through one of the adjustment holes 132 and extends into the mounting hole 1118.

[0049] The clamping base 13 and the clamping arm 11 are connected by a hinge pin 14, which allows the clamping arm 11 to rotate relative to the hinge pin 14. The hinge pin 14 has a simple structure, and the installation steps for installing the clamping arm 11 to the clamping base 13 are also relatively simple, which can reduce the cost of parts and installation.

[0050] In some embodiments, the mounting hole 1118 is a blind hole, and the hinge pin 14 extends into the mounting hole 1118 but does not pass through the mounting hole 1118. In other embodiments, the mounting hole 1118 may also be a through hole, and the hinge pin 14 may pass through the mounting hole 1118 or may only extend into the mounting hole 1118 without passing through the mounting hole 1118.

[0051] In some embodiments of this utility model, the clamping seat 13 and the clamping arm 11 are rotatably connected by a mounting pin and a mating head. The clamping arm 11 has a mounting hole 1118, the mounting pin passes through the mounting hole 1118 and the adjustment hole 132, and the mating head is fixed to one end of the mounting pin, so that the clamping seat 13 and the clamping arm 11 are located between the head of the mating head and the head of the mounting pin, thereby realizing the rotatable connection between the clamping seat 13 and the clamping arm 11.

[0052] Please refer to some embodiments of this utility model. Figure 2 and Figure 3The plurality of adjustment holes 132 includes two sets of adjustment holes 132, each set of adjustment holes 132 including multiple adjustment holes 132 arranged sequentially. Two clamping arms 11 are respectively mounted to the clamping base 13 through the two sets of adjustment holes 132. The plurality of adjustment holes 132 are divided into two sets, with each set containing multiple adjustment holes 132. The two clamping arms 11 are respectively mounted to the clamping base 13 through the two sets of adjustment holes 132. This can be understood as one clamping arm 11 being mounted to the clamping base 13 through one set of adjustment holes 132, and the other clamping arm 11 being mounted to the clamping base 13 through the other set of adjustment holes 132. The positions of both clamping arms 11 are adjustable.

[0053] By dividing the adjustment hole 132 into two groups, the positions of the two clamping arms 11 can be adjusted through different adjustment hole groups.

[0054] In some embodiments, the number of adjustment holes 132 in each set of adjustment holes 132 is the same, which facilitates design and manufacturing. Optionally, the two sets of adjustment holes 132 are symmetrically arranged, that is, the two sets of adjustment holes 132 have the same structure and are symmetrically arranged about the central symmetry line, and the two clamping arms 11 are also symmetrically arranged about the central symmetry line.

[0055] Please refer to some embodiments of this utility model. Figures 2 to 4 The clamping arm 11 includes a conductive part 112 and an insulating base 111 fixedly connected. A first end of the conductive part 112 extends into the insulating base 111, and a second end of the conductive part 112 is exposed outside the insulating base 111 and used for contact and conduction with electronic devices. A probe body 30 or a grounding component extends into the insulating base 111 and contacts and conducts with the first end of the conductive part 112. The conductive part 112 is made of a conductive material, such as copper or aluminum. The insulating base 111 is made of an insulating material, such as plastic. The first end of the conductive part 112 extends into the insulating base 111 and is at least partially enclosed by it. The second end of the conductive part 112 is exposed, and when the electronic device is clamped between the two clamping arms 11, the second end of the conductive part 112 contacts and conducts with the pins of the electronic device. One of the clamping arms 11 is electrically connected to the probe body 30, and in that clamping arm 11, the probe body 30 is in contact with the first end of the conductive part 112 of the clamping arm 11 and conducts electricity. The other clamping arm 11 is electrically connected to the grounding component, and in that clamping arm 11, the grounding component is in contact with the first end of the conductive part 112 of the clamping arm 11 and conducts electricity.

[0056] By setting the conductive part 112 and the insulating seat 111, a portion of the surface of the clamp arm 11 is made into an insulating structure, which can protect and insulate the conductive part 112, and also make the connection between the conductive part 112 and the probe body 30, the conductive part 112 and the grounding component tighter.

[0057] In some embodiments, please refer to Figure 4The insulating base 111 includes a first insulating section 1111 and a second insulating section 1112 fixedly connected. The first insulating section 1111 has a receiving groove 1115 along its extension direction, which communicates with a receiving hole 1116. The first end of the conductive part 112 is located in the receiving groove 1115. The second insulating section 1112 has a receiving hole 1116 arranged along its length direction, and the probe body 30 or the grounding component extends into the receiving hole 1116. Both the first insulating section 1111 and the second insulating section 1112 are made of insulating material. The receiving groove 1115 along the length direction of the first insulating section 1111 can be understood as the first insulating section 1111 being a strip structure, and the extension direction of the receiving groove 1115 being the same as the extension direction of the first insulating section 1111. The first insulating section 1111 can be an arc-shaped strip structure or a straight strip structure; its specific shape is not limited here. The second insulating section 1112 has a receiving hole 1116 arranged along its length direction. It can be understood that the second insulating section 1112 is at least partially hollow, and the hollow part is the receiving hole 1116.

[0058] The receiving groove 1115 ensures that at least a portion of the conductive part 112 is enclosed within the inner wall of the insulating base 111, providing protection and insulation for the conductive part 112. The receiving hole 1116 allows the probe body 30 or the grounding component to extend into the receiving hole 1116 and make contact with the conductive part 112 for conduction.

[0059] In some embodiments, the conductive portion 112 is sheet-shaped, and correspondingly, the receiving groove 1115 is a narrow groove adapted to the shape of the conductive portion 112.

[0060] In some embodiments, the probe body 30 includes a cylindrical portion and a sheet portion connected to each other. The main body of the probe body 30 is cylindrical, and a sheet portion is connected to one end of the cylindrical portion. The sheet portion is more easily connected to the sheet-like conductive portion 112.

[0061] Please refer to some embodiments of this utility model. Figures 2 to 4 The clamping base 13 has a protruding limiting part 131 located between the two clamping arms 11, which limits the rotation angle of the clamping arms 11. When the clamping arms 11 rotate relative to the clamping base 13 to clamp the electronic device, the clamping arms 11 will be stopped by the limiting part 131 after rotating to a predetermined angle to prevent excessive clamping force on the electronic device and damage to it. The opposite sides of the first connecting part 1113 refer to the two sides along the length direction of the clamping arms 11.

[0062] By setting the limiting part 131, the rotation angle of the clamping arm 11 can be limited, thereby preventing the clamping force of the clamping arm 11 on the electronic device from being too large, and thus protecting the electronic device.

[0063] In some embodiments, please refer to Figure 2 and Figure 4 The insulating base 111 has a first connecting portion 1113 for rotatably connecting with the clamping base 13 and a second connecting portion 1114 for connecting with the elastic member 12; the limiting portion 131 and the second connecting portion 1114 are respectively disposed on opposite sides of the first connecting portion 1113.

[0064] By placing the limiting part 131 and the second connecting part 1114 on opposite sides of the first connecting part 1113, the layout of the first connecting part 1113, the second connecting part 1114 and the limiting part 131 is more reasonable, and the space around the connection between the clamping arm 11 and the clamping seat 13 can be fully utilized.

[0065] Optionally, the clamping arm 11 has a clamping end (the second end of the conductive part 112) and a handheld end disposed opposite to each other. The clamping end is used to clamp electronic devices, and the handheld end is for the user to hold and use. The limiting part 131 is disposed opposite to the second connecting part 1114 near the clamping end of the clamping arm 11, and the size of the limiting part 131 is relatively small.

[0066] Optionally, the clamping arm 11 has a clamping end (the second end of the conductive part 112) and a handheld end disposed opposite to each other. The clamping end is used to clamp electronic devices, and the handheld end is for the user to hold. The second connecting part 1114 is disposed away from the clamping end of the clamping arm 11 relative to the limiting part 131. The elastic member 12 is relatively close to the clamping end of the clamping arm 11. In this way, when the user holds the handheld end, the gripping force required is small, which can overcome the elastic force of the elastic member 12 and make the two clamping arms 11 move away from each other.

[0067] In some embodiments, the elastic element 12 is a cylindrical spring, and the second connecting portion 1114 includes a limiting hole 1117, with one end of the cylindrical spring extending into the limiting hole 1117. Both clamping arms 11 are provided with a second connecting portion 1114, and each second connecting portion 1114 is provided with a limiting hole 1117, with both ends of the cylindrical spring extending into the two limiting holes 1117 respectively.

[0068] In some embodiments, the first connecting portion 1113 has the aforementioned mounting hole 1118, which facilitates the rotational connection between the clamping arm 11 and the clamping seat 13.

[0069] Please refer to some embodiments of this utility model. Figure 5 The base assembly 20 includes a base body 21 and a rotating bracket 22 rotatably connected to the base body 21, with a clamping seat 13 connected to the rotating bracket 22. By connecting the clamping seat 13 to the rotating bracket 22, the clamping assembly 10 can be mounted entirely on the rotating bracket 22. When the rotating bracket 22 rotates relative to the base body 21, or when the rotating bracket 22 itself moves, the position and angle of the clamping assembly 10 can be changed.

[0070] By setting the base body 21 and the rotating bracket 22 rotatably connected to the base body 21, the position and angle of the clamping component 10 are adjustable, so that the position and angle of the electronic device clamped by the clamping component 10 are adjustable. This makes it more convenient for users to operate and can be applied to electronic devices of different specifications.

[0071] Please refer to some embodiments of this utility model. Figure 5 The rotating bracket 22 includes a first rotating arm 221, a second rotating arm 222, and a third rotating arm 223. One end of the first rotating arm 221 is ball-jointed to the base body 21, and the other end of the first rotating arm 221 is rotatably connected to the second rotating arm 222. The end of the second rotating arm 222 away from the first rotating arm 221 is ball-jointed to the third rotating arm 223. The clamping seat 13 is connected to the third rotating arm 223. The first rotating arm 221, the second rotating arm 222, and the third rotating arm 223 are connected sequentially. When the first rotating arm 221 rotates relative to the base body 21, when the second rotating arm 222 rotates relative to the first rotating arm 221, and when the third rotating arm 223 rotates relative to the second rotating arm 222, the clamping assembly 10 moves accordingly, thus changing the position and orientation of the electronic device. One end of the first rotating arm 221 is ball-jointed to the base body 21, therefore, one end of the first rotating arm 221 can rotate relative to the base body 21 in multiple directions (three-dimensional rotational connection). The other end of the first rotating arm 221 is rotatably connected to the second rotating arm 222. Therefore, the second rotating arm 222 can rotate relative to the first rotating arm 221 in one direction (two-dimensional rotational connection). The end of the second rotating arm 222 away from the first rotating arm 221 is ball-jointed to the third rotating arm 223. Therefore, the third rotating arm 223 can rotate relative to the second rotating arm 222 in multiple directions (three-dimensional rotational connection).

[0072] By setting the first rotating arm 221, the second rotating arm 222 and the third rotating arm 223, the clamping assembly 10 can be rotated in multiple directions, thereby making it easier to adjust the position of the electronic device.

[0073] In some embodiments, the clamping base 13 is fixedly connected to the third rotating arm 223, making the connection between the clamping assembly 10 and the base assembly 20 more stable.

[0074] In some embodiments, the clamping base 13 is detachably connected to the third rotating arm 223, making the clamping assembly 10 detachable and facilitating the replacement of different clamping assemblies 10.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
