During operation, the testing head is usually connected to the testing instrument sequentially via wires and electrical connectors for measurement. However, during testing, the wires are easily pulled by external forces, which can cause them to detach from the electrical connectors. This instability in the connection between the testing head and the testing instrument can negatively impact the test results. Utility Model Content

[0003] This utility model discloses a testing instrument to solve the problem that the wires of the testing instruments involved in the related technology are easily separated from the electrical connector when pulled by external force, making it difficult to stably connect the testing head to the testing instrument.

[0005] This application discloses a testing instrument, which includes a housing, a first clamping member, a second clamping member, and a testing component;

[0006] The housing is provided with an electrical interface. The first clamping member and the second clamping member are disposed opposite to each other on the housing, and the two form an accommodating space between them. The accommodating space is opposite to the electrical interface. The first clamping member is fixedly connected to the housing, and the second clamping member is slidably connected to the housing so that the second clamping member can switch between a first position and a second position. The detection component includes an electrical connector, a wire, and a detection head. The detection head and the electrical connector are respectively connected to the wire.

[0007] When the second clamping member is in the first position, the electrical interface is used to connect with the electrical connector, the receiving space is used to receive the wire, and the second clamping member and the first clamping member are used to clamp and fix the wire.

[0008] When the second clamping member is in the second position, the second clamping member separates from the first clamping member.

[0010] The detection instrument disclosed in this application improves the structure of detection instruments related to the relevant technology by setting a first clamping member and a second clamping member. The first clamping member and the second clamping member are disposed opposite to each other on the housing, so that the accommodating space formed by the first clamping member and the second clamping member is opposite to the electrical interface of the housing. The first clamping member is fixedly connected to the housing, and the second clamping member is slidably connected to the housing, so that the second clamping member can switch between a first position and a second position. In the first position, the electrical interface can be connected to the detection head in sequence through the electrical connector and the wire. The accommodating space can accommodate the wire, and the second clamping member and the first clamping member can clamp and fix the wire to prevent the wire from being pulled and separated from the electrical connector by external force.

[0029] Please refer to Figures 1 to 5 This application discloses a testing instrument, which includes a housing 100, a first clamping member 210, a second clamping member 310, and a testing component.

[0030] The housing 100 is the basic component of the testing instrument, providing mounting positions for other components of the testing instrument. The first clamping member 210 and the second clamping member 310 are both located in the housing 100. In addition, the housing 100 is also used to form some functional spaces or structures, such as the electrical interface 110, the protrusion 120, the mounting groove 130, and the inner cavity, as described later.

[0031] The detection assembly is the core component of the detection instrument, which includes an electrical connector, a wire, and a detection head. The detection head and the electrical connector are connected to the wire. The detection head is used for detection, and the electrical connector is used to connect to the electrical interface 110 of the housing 100. This allows the detection head to be connected to the electrical interface sequentially through the wire and the electrical connector for detection. Specifically, the detection head and the electrical connector can be connected to the two ends of the wire, respectively.

[0032] The first clamping member 210 and the second clamping member 310 are the core components of the testing instrument for clamping and fixing the wires. For example... Figure 1 As shown, the first clamping member 210 and the second clamping member 310 are disposed opposite to each other on the housing 100, and the two form a receiving space 400. The receiving space 400 is opposite to the electrical interface 110 to accommodate wires. The first clamping member 210 is fixedly connected to the housing 100, and the second clamping member 310 is slidably connected to the housing 100 so that the second clamping member 310 can switch between a first position and a second position.

[0033] During operation, the second clamping member 310 can slide towards the first clamping member 210 to switch to the first position. When the second clamping member 310 is in the first position, the electrical interface 110 is used to connect to the electrical connector, allowing the electrical interface 110 to connect to the detection head sequentially through the electrical connector and the wire, enabling detection. Simultaneously, the receiving space 400 is used to receive the wire, and the second clamping member 310 and the first clamping member 210 clamp and secure the wire. This allows the wire located in the receiving space 400 to be clamped and secured by the second clamping member 310 and the first clamping member 210 during detection.

[0034] The second clamp 310 can slide away from the first clamp 210 to switch to the second position. When the second clamp 310 is in the second position, the second clamp 310 is separated from the first clamp 210. At this time, the electrical connector can be separated from the electrical interface 110, and the wire can be moved out of the receiving space 400, thereby ending the detection.

[0035] The detection instrument disclosed in this application improves the structure of detection instruments related to the relevant technology by setting a first clamping member 210 and a second clamping member 310. The first clamping member 210 and the second clamping member 310 are positioned opposite each other on the housing 100, so that the receiving space 400 formed between the first clamping member 210 and the second clamping member 310 is opposite to the electrical interface 110. Furthermore, the first clamping member 210 is fixedly connected to the housing 100, and the second clamping member 310 is slidably connected to the housing 100, thereby... The second clamping member 310 can switch between a first position and a second position, so that when the second clamping member 310 is in the first position, the electrical interface 110 can be connected to the detection head in sequence through the electrical connector and the wire, the accommodating space 400 can accommodate the wire, and the second clamping member 310 and the first clamping member 210 can clamp and fix the wire to prevent the wire from being pulled apart from the electrical connector by external force; and when the second clamping member 310 is in the second position, the second clamping member 310 can be separated from the first clamping member 210.

[0036] When the second clamping member 310 is in the first position, this structure can clamp and fix the wire by the second clamping member 310 and the first clamping member 210, so as to prevent the wire from being pulled by external force and separated from the electrical connector. This allows the detection head to be stably connected to the electrical interface 110 through the wire and the electrical connector, which helps to improve the stability of the connection between the detection head and the electrical interface 110, and thus helps to ensure the stability of the detection.

[0037] Please continue to refer to this. Figure 1 In one embodiment, there can be multiple electrical interfaces 110, multiple first clamping members 210, multiple second clamping members 310, and multiple detection components. Multiple first clamping members 210 can be paired one-to-one with multiple second clamping members 310, such that each first clamping member 210 and each second clamping member 310 can form a receiving space 400. Multiple receiving spaces 400 can be paired one-to-one with the electrical interfaces 110, and are used to receive the wires of multiple detection components.

[0038] This structure allows the wires of each detection component to be clamped and fixed by the corresponding second clamp 310 and the corresponding first clamp 210, thereby preventing the wires of each detection component from being pulled apart by external force and separating from the electrical connector of the corresponding detection component. This allows the detection head of each detection component to be stably connected to the corresponding electrical interface 110 through the wires and electrical connectors of the corresponding detection component.

[0039] In a further technical solution, the housing 100 may include a protrusion 120, which may be provided with a groove 121. The second clamping member 310 is slidably disposed in the groove 121, and the opening of the groove 121 may be opposite to the first clamping member 210. This allows the second clamping member 310 to slide outward through the opening of the groove 121, so that the second clamping member 310 can approach the first clamping member 210, thereby allowing the second clamping member 310 to switch to a first position. At the same time, it also allows the second clamping member 310 to slide inward through the opening of the groove 121, so that the second clamping member 310 can move away from the first clamping member 210, thereby allowing the second clamping member 310 to switch to a second position.

[0040] In other words, the sliding direction of the second clamping member 310 can be parallel to the opening of the groove 121, so that the sliding of the second clamping member 310 can be guided by the groove 121, making the sliding of the second clamping member 310 more stable, thereby enabling the second clamping member 310 to switch stably between the first position and the second position.

[0041] In the specific operation, when the second clamping member 310 is in the first position, the second clamping member 310 can be at least partially disposed outside the slide groove 121, so that the second clamping member 310 and the first clamping member 210 are clamped together, thereby clamping and fixing the wire located in the receiving space 400. When the second clamping member 310 is in the second position, the second clamping member 310 can be disposed within the slide groove 121, so that the second clamping member 310 is separated from the first clamping member 210, thereby allowing the electrical connector to be separated from the electrical interface 110, and the wire to be moved out of the receiving space 400, so that the testing can be completed.

[0042] Of course, in other embodiments, the housing 100 may be provided with a guide rail, and the second clamping member 310 may be slidably connected to the housing 100 via the guide rail, thereby allowing the second clamping member 310 to switch between a first position and a second position.

[0043] In an optional technical solution, the housing 100 may further include a reinforcing portion 140, which may be distributed on the outer surface of the housing 100. The protrusion 120 and the first clamping member 210 may both be fixed to the reinforcing portion 140. This structure can improve the overall strength of the housing 100 through the reinforcing portion 140, thereby enabling the first clamping member 210 and the second clamping member 310 to be more stably connected to the housing 100.

[0044] Please refer to Figure 2 and Figure 3In this embodiment, the protrusion 120 may have a through hole 122, which can communicate with the slide groove 121. The detection instrument may also include a drive rod 320, and the second clamping member 310 may be fixedly connected to the drive rod 320. The drive rod 320 may pass through the through hole 122 and slide with the through hole 122, thereby driving the second clamping member 310 to slide and switch between a first position and a second position. Specifically, the drive rod 320 may be a round rod or a rectangular rod, and this embodiment does not limit the specific structure of the drive rod 320.

[0045] This structure makes operation more convenient for users by setting up a drive rod 320, thereby reducing the difficulty of driving and making it easier for the second clamping member 310 to switch between the first position and the second position.

[0046] In the more preferred technical solutions, such as Figure 2 As shown, the detection instrument may also include a limiting member 330. The first end of the drive rod 320 may be fixedly connected to the second clamping member 310, and the second end of the drive rod 320 may extend through the through hole 122 to the outside of the slide groove 121 and be fixedly connected to the limiting member 330.

[0047] During operation, when the second clamping member 310 is in the first position, the limiting member 330 can abut against the port of the through hole 122 facing away from the slide groove 121 to restrict the second clamping member 310 from sliding further out of the slide groove 121. This limits the sliding stroke of the second clamping member 310 and prevents it from sliding excessively and impacting the first clamping member 210, which could affect the stability of the first clamping member 210 on the housing 100. It also prevents the second clamping member 310 from sliding further out of the slide groove 121 and falling off, thus preventing its loss.

[0048] When the second clamping member 310 is in the second position, the limiting member 330 can be separated from the protrusion 120, so as not to affect the second clamping member 310 from sliding into the groove 121, so that the second clamping member 310 can be switched to the second position normally.

[0049] In a feasible technical solution, the detection instrument may further include a first magnetic element 220 and a second magnetic element 340. The first magnetic element 220 may be fixed to the first clamping member 210, and the second magnetic element 340 may be fixed to the second clamping member 310. Specifically, both the first magnetic element 220 and the second magnetic element 340 may be permanent magnets or electromagnets, and the embodiments of this application do not limit this.

[0050] In the specific working process, when the second clamping member 310 is in the first position, the first magnetic member 220 can magnetically engage with the second magnetic member 340 to further assist the clamping engagement between the second clamping member 310 and the first clamping member 210. The first magnetic member 220 can contact the second magnetic member 340 to achieve a more effective magnetic engagement. When the second clamping member 310 is in the second position, the first magnetic member 220 can separate from the second magnetic member 340, allowing the second clamping member 310 to detach from the first clamping member 210.

[0051] This structure, through the cooperation between the first magnetic component 220 and the second magnetic component 340, enables the second clamping component 310 and the first clamping component 210 to be quickly clamped together or separated, thereby improving operating efficiency, reducing wear, and extending service life.

[0052] Of course, in other embodiments, when the second clamping member 310 is in the first position, the second clamping member 310 and the first clamping member 210 can be connected by snap-fit ​​or threaded engagement to assist the clamping engagement of the second clamping member 310 and the first clamping member 210.

[0053] Furthermore, such as Figure 4 As shown, the end of the first clamping member 210 away from the housing 100 may be provided with a positioning groove 211. The opening of the positioning groove 211 may be opposite to the second clamping member 310 so that the second magnetic member 340 can cooperate with the positioning groove 211.

[0054] In the specific working process, when the second clamping member 310 is in the first position, the second magnetic member 340 can be located in the positioning groove 211, so that the second magnetic member 340 can be positioned and engaged with the positioning groove 211, thereby enabling the second magnetic member 340 to be more stably magnetically engaged with the first magnetic member 220, which in turn helps to improve the stability of the clamping engagement between the second clamping member 310 and the first clamping member 210.

[0055] When the second clamping member 310 is in the second position, the second magnetic member 340 can be located outside the positioning groove 211 so that the first magnetic member 220 can be separated from the second magnetic member 340, thereby allowing the second clamping member 310 to be separated from the first clamping member 210.

[0056] Optionally, the first magnetic component 220 can be disposed within the positioning groove 211 and fixed to the inner bottom wall of the positioning groove 211, thereby making the magnetic attraction between the first magnetic component 220 and the second magnetic component 340 more effective. Of course, the first magnetic component 220 can also be disposed outside the positioning groove 211 and fixed to the outer bottom wall of the positioning groove 211, so as to reduce the installation difficulty of the first magnetic component 220 and facilitate its installation.

[0057] Please refer to Figure 1 and Figure 5 In this embodiment of the application, the housing 100 may be provided with a mounting groove 130, and the side wall of the mounting groove 130 may be provided with a plurality of openings 131. The mounting groove 130 can communicate with the inner cavity of the housing 100 through the plurality of openings 131, so that water vapor in the inner cavity can enter the mounting groove 130 through the plurality of openings 131.

[0058] The testing instrument may also include a moisture-proof container 510, which may be provided with a receiving groove 511. The moisture-proof container 510 may be detachably installed in the mounting groove 130. The groove of the receiving groove 511 is used to face multiple openings 131, which allows moisture in the inner cavity to enter the receiving groove 511 through the multiple openings 131 and the groove of the receiving groove 511 when the moisture-proof container 510 is installed in the mounting groove 130.

[0059] Meanwhile, the receiving tank 511 is used to house the moisture-proof component, which absorbs moisture entering the receiving tank 511 from the inner cavity, keeping the inner cavity relatively dry. This improves the working environment of the inner cavity and allows the electronic components inside to operate more stably. Specifically, the moisture-proof component can be a temperature-sensitive hydrogel, activated carbon, or silica gel desiccant. This application embodiment does not limit the specific type of moisture-proof component.

[0060] To ensure stable moisture absorption, the moisture-proof container 510 can be periodically removed from the mounting slot 130 for regular replacement. To facilitate the removal and installation of the moisture-proof container 510, the opening of the mounting slot 130 can be located on the outer surface of the housing 100. Furthermore, to enhance moisture absorption capacity, multiple moisture-proof containers 510 and mounting slots 130 can be used.

[0061] Optionally, the testing instrument may also include an auxiliary operation unit 530, which can be fixedly connected to the moisture-proof container 510 and can be located outside the mounting groove 130. This allows for easier disassembly of the moisture-proof container 510 via the auxiliary operation unit 530, thereby reducing disassembly difficulty and facilitating maintenance. Specifically, the auxiliary operation unit 530 can be a pull rope or a pull ring; the specific structure of the auxiliary operation unit 530 is not limited in this embodiment.

[0062] In one embodiment, the detection instrument may also include multiple filters 600, which may cover multiple openings 131 respectively, thereby preventing impurities, dust and the like from entering the inner cavity through the multiple openings 131 and easily affecting the working environment of the inner cavity, so that the electronic components in the inner cavity can work more stably.

[0063] In optional technical solutions, the testing instrument may further include a third magnetic component and a fourth magnetic component 520. The third magnetic component can be fixed in the mounting groove 130, and the fourth magnetic component 520 can be fixed in the moisture-proof container 510. When the moisture-proof container 510 is installed in the mounting groove 130, the third magnetic component and the fourth magnetic component 520 can magnetically engage, thereby preventing the moisture-proof container 510 from shaking in the mounting groove 130 and ensuring that the moisture-proof container 510 is stably installed in the mounting groove 130. Specifically, both the third magnetic component and the fourth magnetic component 520 can be permanent magnets or electromagnets, and this application embodiment does not limit this.

[0064] Of course, in other embodiments, the moisture-proof container 510 can also be detachably installed in the mounting groove 130 by means of snap-fit ​​or threaded engagement.

[0065] To reduce manufacturing difficulty, the third magnetic component can be located near the opening of the mounting groove 130. When the moisture-proof container 510 is installed in the mounting groove 130, the fourth magnetic component 520 can be positioned opposite the third magnetic component.

[0066] In feasible technical solutions, the testing instrument may also include a display screen 700 and an operation button 800. The display screen 700 and the operation button 800 may both be located in the housing 100. The display screen 700 can display testing information, and the operation button 800 can input testing commands.

[0067] In the examples of this application, the testing instrument may be a multimeter, oscilloscope, or grounding resistance tester, etc. The embodiments of this application do not limit the specific type of testing instrument.

[0068] The above embodiments of this utility model focus on describing the differences between the various embodiments. As long as the different optimization features of the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0069] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
