Description

Technical Field

[0001] This application relates to the field of testing technology, and in particular to a foolproof inspection tool. Background Technology

[0002] In the production and application of special heat sinks for 5G communication, due to differences in factors such as power consumption, cost and weight of internal components, it is necessary to develop similar materials with different numbers of RBC teeth. These heat sinks exist in two states: full teeth and missing teeth, and their shapes are similar, which places high demands on detection accuracy and error prevention.

[0003] Currently, error-proofing inspections for radiator fins with full / missing teeth mainly rely on three traditional methods: First, manual visual inspection, which depends on the operator's visual judgment. Prolonged operation can easily lead to visual fatigue, making it difficult to consistently distinguish the differences in fins between similar materials and posing a risk of mixed materials flowing out. Second, conformal tooling inspection, which requires inserting conformal tooling into the gaps between radiator fins and manually judging whether the tooling is fully inserted to determine the fin condition. This process is cumbersome and inefficient, failing to meet the high-efficiency inspection requirements of mass production. Third, CCD visual inspection, while achieving a certain degree of automation, involves lengthy equipment setup and high equipment purchase and maintenance costs, hindering cost control and making it difficult to widely apply in small and medium-sized production scenarios or cost-sensitive projects.

[0004] Existing testing methods suffer from drawbacks such as low efficiency, poor reliability, high cost, or reliance on human experience. There is an urgent need for a foolproof inspection tool that is simple in structure, intuitive in judgment, cost-controllable, and adaptable to the testing needs of special heat sinks for 5G communication, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0005] One object of this application is to provide a foolproof inspection tool that at least solves the above-mentioned problems.

[0006] To achieve the above objectives, some embodiments of this application provide a foolproof inspection tool for inspecting heat sinks, including:

[0007] The base has at least one mounting slot.

[0008] The front panel covers the opening side of the base mounting groove and has a through groove corresponding to the mounting groove.

[0009] The contact assembly includes a pair of first conductive blocks and second conductive blocks. The first conductive block is disposed in the mounting groove, and the second conductive block is slidably disposed in the through groove. The second conductive block can reciprocate along the axial direction of the through groove.

[0010] The lamp assembly, located on the side of the base away from the front panel, includes an indicator lamp and a power supply unit, which is electrically connected to the indicator lamp to provide operating power.

[0011] The first conductive block, the second conductive block, the indicator light, and the power supply unit form a series circuit through wires. When the heat sink to be tested pushes the second conductive block and moves along the through groove toward the first conductive block, and the second conductive block contacts the first conductive block, the series circuit is turned on, the indicator light is powered on, and it emits an indicator light.

[0012] Compared with related technologies, the solution provided in this application constructs an automated detection mechanism of mechanical contact-circuit conduction-light indication through the collaborative design of the base, front panel, contact assembly, and lamp assembly. When the heat sink under test pushes against the second conductive block and contacts the first conductive block, the series circuit is activated, causing the indicator light to illuminate, directly feeding back the detection result. This fundamentally avoids the shortcomings of traditional methods, such as easy fatigue from manual visual inspection, the need for manual judgment of contouring fixtures, and the complexity and high cost of CCD equipment debugging. It eliminates the need to rely on operator experience, simplifies the detection process, and makes the results intuitive, meeting the error-proof detection requirements of 5G special heat sinks in full / missing tooth states.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] Combination Figures 1 to 10 As shown in the figure, an embodiment of this disclosure provides a foolproof inspection tool for inspecting a heat sink, including: a base 10, a front panel 20, a contact assembly, and a lamp assembly.

[0039] The base 10 has at least one mounting groove 101; the front panel 20 covers the opening side of the mounting groove 101 of the base 10 and has a through groove 201 corresponding to the mounting groove 101; the contact assembly includes a pair of first conductive blocks 30 and second conductive blocks 40, the first conductive blocks 30 are disposed in the mounting groove 101, the second conductive blocks 40 slide through the through groove 201, and the second conductive blocks 40 can reciprocate along the axial direction of the through groove 201; the lamp assembly is disposed on the side of the base 10 away from the front panel 20, including an indicator lamp 60 and a power supply unit, the power supply unit is electrically connected to the indicator lamp 60 to provide working power; wherein, the first conductive block 30, the second conductive block 40, the indicator lamp 60 and the power supply unit form a series circuit through wires; when the heat sink to be tested pushes the second conductive block 40 to move along the through groove 201 toward the first conductive block 30, and the second conductive block 40 contacts the first conductive block 30, the series circuit is turned on, the indicator lamp 60 is powered on and emits an indicator light.

[0040] The foolproof inspection fixture provided in this embodiment constructs an automated detection mechanism of mechanical contact-circuit conduction-light indication through the collaborative design of the base 10, front panel 20, contact assembly, and lamp assembly. When the heat sink under test pushes the second conductive block 40 into contact with the first conductive block 30, the series circuit is activated, causing the indicator lamp 60 to light up, directly feeding back the detection result. This fundamentally avoids the shortcomings of traditional methods such as easy fatigue from manual visual inspection, the need for manual judgment of contouring fixtures, and the complexity and high cost of CCD equipment debugging. It eliminates the need to rely on operator experience, simplifies the detection process, and makes the results intuitive, meeting the foolproof detection requirements of 5G special heat sinks in full / missing tooth states.

[0041] One end of the first conductive block 30 is electrically connected to the output terminal of the power supply unit, and the other end of the first conductive block 30 is a conductive contact terminal; one end of the second conductive block 40 is electrically connected to the signal input terminal of the indicator lamp 60 through a wire, and the other end of the second conductive block 40 is a conductive contact terminal; the first conductive block 30, the second conductive block 40, the indicator lamp 60 and the power supply unit form a series circuit through wires; when the heat sink to be tested pushes the second conductive block 40 to move along the through groove 201 toward the first conductive block 30, and the conductive contact terminal of the second conductive block 40 contacts the conductive contact terminal of the first conductive block 30, the series circuit is turned on, the indicator lamp 60 is powered on and emits an indicator light.

[0042] By establishing specific electrical connection paths between the first conductive block 30 and the output terminal of the power supply unit, and between the second conductive block 40 and the signal input terminal of the indicator light 60, the conduction logic of the series circuit is ensured to be clear and stable.

[0043] In some embodiments, when multiple sets of contact components are provided, connecting multiple first conductive blocks 30 in series ensures that all first conductive blocks 30 are in the same circuit path, and connecting multiple second conductive blocks 40 in series also ensures that all second conductive blocks 40 are included in the same circuit path. This series connection method avoids the confusion of detection logic caused by the independent circuits of each set of contact components. It is only necessary to determine whether the overall series circuit is conductive (whether the indicator light 60 is lit) to complete the detection, without having to check the status of each set of contacts one by one.

[0044] Compared to designing multiple sets of contact components as parallel circuits or independent circuits, the method of connecting multiple first conductive blocks 30 in series and multiple second conductive blocks 40 in series can reduce the number of wire connections and circuit nodes, making the internal circuit layout of the fixture simpler.

[0045] Because multiple sets of contact components are connected in series to form a "one-vote veto" detection logic (if any set of key contacts is not connected, the entire circuit is broken), the detection result is presented intuitively by the indicator light 60 "on / off", without the need for the operator to judge or perform complex analysis on the conduction status of multiple sets of contacts one by one.

[0046] Optionally, the first conductive block 30 and the second conductive block 40 are made of conductive material. This ensures conductivity when the two conductive blocks are in contact, guaranteeing effective conduction of the series circuit.

[0047] Optionally, the front panel 20 is detachably connected to the base 10 by screws. Using screws to achieve a detachable connection between the front panel 20 and the base 10 facilitates the disassembly, maintenance, and replacement of the front panel 20.

[0048] Optionally, the foolproof inspection tool also includes a reset spring 50, which is disposed between the first conductive block 30 and the second conductive block 40, for automatic reset after the second conductive block 40 is moved by pressure.

[0049] The reset spring 50 automatically resets after the second conductive block 40 is pressed and moved, eliminating the need for manual adjustment of the second conductive block 40's position by the operator. This reduces operator steps and labor intensity, while also allowing the inspection fixture to quickly switch to the next inspection state, avoiding interruptions in the inspection process caused by manual reset and improving overall inspection efficiency.

[0050] Optionally, one end of the first conductive block 30 is electrically connected to the output terminal of the power supply unit, and the other end of the first conductive block 30 is a conductive contact terminal; one end of the second conductive block 40 is electrically connected to the signal input terminal of the indicator lamp 60 through a wire, and the other end of the second conductive block 40 is a conductive contact terminal; wherein, one end of the reset spring 50 is sleeved or embedded in the conductive contact terminal of the first conductive block 30, and the other end is sleeved or embedded in the conductive contact terminal of the second conductive block 40.

[0051] By sleeved or embedded at both ends of the reset spring 50 on the conductive contact ends of the first conductive block 30 and the conductive contact ends of the second conductive block 40, the reset failure problem caused by displacement or detachment of the reset spring 50 during the detection process can be prevented. At the same time, it ensures that the reset force of the reset spring 50 on the second conductive block 40 is uniform, and ensures the consistency of the position of the second conductive block 40 after each reset.

[0052] Optionally, the first conductive block 30 is detachably connected to the bottom of the mounting groove 101 of the base 10 by screws, and is also electrically connected to the wire by screws.

[0053] The screw-removable connection design facilitates the disassembly and maintenance of the first conductive block 30. When the first conductive block 30 is worn or its conductivity decreases, it can be quickly disassembled and replaced, reducing the difficulty of fixture maintenance. On the other hand, the screw enables the electrical connection between the first conductive block 30 and the wire, making the connection more secure. This avoids poor circuit contact caused by loose wires, ensures stable conduction of the series circuit, and improves the reliability of the test.

[0054] Optionally, the bottom wall of the mounting groove 101 has a groove 102, and the surface of the first conductive block 30 that fits the bottom of the mounting groove 101 has a protruding positioning part 301. The positioning part 301 is embedded in the groove 102, and the first conductive block 30 is fixed to the bottom wall of the mounting groove 101 by screws.

[0055] The groove 102 on the bottom wall of the mounting groove 101 forms a fitting structure with the positioning part 301 of the first conductive block 30, which can accurately position the first conductive block 30 in the mounting groove 101 and avoid poor contact between the first conductive block 30 and the second conductive block 40 due to installation misalignment. At the same time, the screw fixing further enhances the stability of the installation of the first conductive block 30 and ensures the consistency of the contact position of the two conductive blocks.

[0056] Optionally, the conductive contact end of the first conductive block 30 is formed in a protruding structure to ensure complete contact with the conductive contact end of the second conductive block 40.

[0057] The conductive contact end of the first conductive block 30 has a protruding structure, which can increase the contact area with the conductive contact end of the second conductive block 40, ensuring that the two conductive blocks can fit together completely when in contact, and avoiding problems such as poor circuit conduction or open circuit due to insufficient contact area.

[0058] Optionally, the positioning part 301 of the first conductive block 30 is coaxially arranged with the conductive contact end of the first conductive block 30.

[0059] The positioning part 301 is coaxially arranged with the conductive contact end of the first conductive block 30, which can ensure that after the first conductive block 30 is accurately installed by the positioning part 301, its conductive contact end can be coaxially aligned with the conductive contact end of the second conductive block 40, avoiding problems such as contact offset and insufficient contact area caused by the two being out of axis.

[0060] Optionally, a frustum 302 is further formed on the surface of the conductive contact end of the first conductive block 30 for mounting the reset spring 50. The reset spring 50 is sleeved on the frustum 302 and abuts against the conductive contact end of the first conductive block 30.

[0061] The frustum 302 at the conductive contact end of the first conductive block 30 provides a precise mounting and positioning reference for the return spring 50, ensuring that the return spring 50 is stably fitted onto the frustum 302 and abuts against the conductive contact end, preventing the return spring 50 from being misaligned or falling off. Simultaneously, the frustum 302 restricts the radial displacement of the return spring 50, ensuring uniform force during compression and reset, and guaranteeing the stability and consistency of the reset of the second conductive block 40.

[0062] Optionally, the conductive contact end of the first conductive block 30 and / or the conductive contact end of the second conductive block 40 are provided with a receiving groove 401 to receive the compressed return spring 50.

[0063] The receiving groove 401 can provide a receiving space for the return spring 50 when it is compressed, so as to prevent the return spring 50 from deforming or twisting due to lack of receiving space after compression, or from hindering the contact between the two conductive blocks.

[0064] Optionally, the conductive contact end of the first conductive block 30 and / or the conductive contact end of the second conductive block 40 are constructed with a protruding structure so that the reset spring 50 is sleeved and the height of the protruding structure is sufficient to accommodate the compressed reset spring 50.

[0065] The protruding structure serves two purposes: firstly, it provides a positioning reference for the reset spring 50, ensuring accurate installation and preventing it from easily falling off; secondly, the height of the protruding structure is adapted to the length of the compressed reset spring 50, allowing it to be fully accommodated when compressed, avoiding structural interference or deformation caused by the spring being exposed after compression. This prevents interference with the contact and conductivity between the two conductive blocks.

[0066] Optionally, the base 10 may also be constructed with a wire groove 103 that connects to the mounting groove 101 for burying wires.

[0067] The wire groove 103 can bury and store the wires of the series circuit, avoiding wear, entanglement or accidental pulling caused by exposed wires, protecting the wires from damage and extending their service life; at the same time, it makes the internal structure of the fixture more regular and reduces the interference of wires on other components (such as the sliding of the second conductive block 40).

[0068] Similarly, the front panel 20 can also be constructed with a groove 103 for burying wires.

[0069] Optionally, the second conductive block 40 is provided with a boss 402 along the circumferential direction, and the boss 402 stops the edge of the through groove 201; wherein, the front panel 20 is provided with an annular groove 202 surrounding the through groove 201 on the surface of the side that is attached to the base 10, the annular groove 202 is adapted to the boss 402 to accommodate the boss 402, so as to prevent the second conductive block 40 from coming out of the through groove 201 after the front panel 20 and the base 10 are assembled;

[0070] The boss 402 of the second conductive block 40 forms a stop and receiving fit with the annular groove 202 of the front panel 20, which can limit the range of movement of the second conductive block 40 along the axial direction of the through groove 201, prevent the second conductive block 40 from falling out of the through groove 201, and ensure the installation stability of the second conductive block 40. At the same time, the design of the annular groove 202 to receive the boss 402 avoids structural interference caused by the exposed boss 402, and ensures the flatness of the overall structure of the fixture after the front panel 20 and the base 10 are assembled, so as not to affect the contact testing of the heat sink under test and the front panel 20.

[0071] Optionally, the conductive contact end of the second conductive block 40 is formed with a protruding structure, and the reset spring 50 is sleeved on the outside of the conductive contact end of the second conductive block 40.

[0072] The reset spring 50 is sleeved on the outside of the conductive contact end of the second conductive block 40. The reset spring 50 can be directly driven to compress and reset by the movement of the second conductive block 40, so that the reset spring 50 is subjected to force more directly and the reset response is faster. At the same time, it avoids interference between the reset spring 50 and other components, and improves the timeliness and stability of the reset of the second conductive block 40.

[0073] Optionally, the conductive contact end of the second conductive block 40 is provided with a receiving groove 401, and the reset spring 50 is inserted into the receiving groove 401. When the first conductive block 30 is in contact with the second conductive block 40, the conductive contact end of the first conductive block 30 is inserted into the receiving groove 401 of the conductive contact end of the second conductive block 40.

[0074] The receiving slot 401 allows the conductive contact end of the first conductive block 30 to be inserted when the two conductive blocks are in contact. This increases the contact area between the two conductive blocks, ensuring stable circuit conduction. Furthermore, the insertion mechanism ensures precise alignment of the two conductive blocks, preventing poor conduction due to contact misalignment. Simultaneously, a return spring 50 can be installed within the receiving slot 401, allowing for more organized spring storage without affecting the contact between the two conductive blocks, thus improving the compactness and reliability of the fixture structure.

[0075] Optionally, the foolproof inspection tool also includes a positioning component, located on the base 10, for positioning the heat sink to be inspected.

[0076] The positioning component can accurately position the heat sink under test, preventing displacement of the heat sink during the test and avoiding deviation in the pushing position with the second conductive block 40, which could lead to false judgments. The positioning component ensures that the heat sink is placed in the same position for each test, guaranteeing the consistency of the test conditions.

[0077] Optionally, the positioning component includes: a positioning plate 70, disposed on the edge of the base 10 and perpendicular to the front panel 20; used to abut against the heat sink to be tested and limit the displacement of the heat sink to be tested.

[0078] The positioning plate 70 is perpendicular to the front panel 20 and located on the edge of the base 10. It can limit the displacement of the heat sink in the direction parallel to the front panel 20 by abutting against the heat sink to be tested, so as to avoid the heat sink shifting laterally and causing the position of the second conductive block 40 to be inaccurate.

[0079] Optionally, the positioning plate 70 is detachably connected to the base 10 by screws.

[0080] The detachable screw connection makes the installation and replacement of the positioning plate 70 more convenient. When it is necessary to adjust the position of the positioning plate 70 to adapt to different specifications of heat sinks or to replace the positioning plate 70 of different sizes, there is no need to modify the base 10. The adjustment can be completed simply by removing the screws, which improves the adaptability of the fixture to heat sinks of different specifications.

[0081] Optionally, the positioning plate 70 can be one or two pieces. In this embodiment, there are two positioning plates 70, which are arranged sequentially along the side of the base 10. The number of positioning plates 70 can be flexibly set according to the shape of the heat sink to be tested and the positioning requirements.

[0082] Optionally, the positioning component further includes: a positioning pin 80, disposed on the surface of the base 10 and passing through the front panel 20; used for insertion and positioning with the heat sink to be tested, limiting the displacement of the heat sink to be tested.

[0083] The positioning pin 80 passes through the front panel 20 and is located on the surface of the base 10. It can be inserted into the positioning hole on the heat sink to be tested to achieve precise positioning of the heat sink and restrict the translation and rotation of the heat sink in the direction parallel to the front panel 20. In conjunction with the positioning plate 70, it can further ensure the accurate pushing position of the heat sink and the second conductive block 40, avoid detection misjudgment caused by heat sink misalignment, and improve the accuracy of the detection results.

[0084] Optionally, multiple locating pins 80 can be provided on the base 10 as needed. Multiple locating pins 80 can be provided as needed according to the number and position of the locating holes of the heat sink to be tested. Multi-point insertion positioning further enhances the positioning stability of the heat sink and avoids possible rotation or displacement of the heat sink when a single locating pin 80 is used for positioning.

[0085] Optionally, the front panel 20 is provided with a clearance groove 203, which is used to avoid the protruding structure of the heat sink under test when the heat sink under test is attached to the front panel 20.

[0086] The clearance groove 203 can avoid protruding structures (such as teeth or protrusions of a specific shape) on the heat sink when it is attached to the front panel 20, so as to avoid interference between the protruding structure and the front panel 20, which would prevent the heat sink from being completely attached to the front panel 20 and thus affect the normal pushing and detection of the second conductive block 40.

[0087] Optionally, at least some of the second conductive blocks 40 are arranged in a position corresponding to the toothed position of the heat sink under full tooth state, and at least some of the second conductive blocks 40 are arranged in a position corresponding to the toothed gap position of the heat sink under full tooth state.

[0088] By aligning the arrangement of the second conductive block 40 with the position of the toothed plate in the full-tooth state of the heat sink, the conductivity of the second conductive block 40 during testing can determine whether the heat sink is in a full-tooth state. If the second conductive block 40 at the corresponding toothed plate position is pushed and connected, it can be determined that the heat sink is in a full-tooth state and is qualified; otherwise, it is in a missing tooth state or mixed with other materials. This embodiment achieves accurate identification of the full-tooth / missing-tooth state of the heat sink.

[0089] It should be noted that, since different heat sinks require different tooth positions, the position of the contact assembly can be set as needed according to the actual situation, that is, it can be adjusted according to the actual situation.

[0090] When the arrangement position of the second conductive block 40 corresponds to the position of the tooth gap in the full tooth state of the heat sink to be tested, the second conductive block 40 can play a positioning role, that is, the second conductive block 40 is inserted into the tooth gap to prevent the heat sink from moving.

[0091] Optionally, the lamp assembly also includes a lamp holder 90, detachably connected to the side of the base 10 away from the front panel 20, for mounting the indicator lamp 60 and the power supply unit.

[0092] The lamp holder 90 is detachably connected to the base 10, facilitating the installation, maintenance, and replacement of the indicator lamp 60 and the power supply unit. When the indicator lamp 60 is damaged or the power supply unit (such as a battery) is depleted, the lamp holder 90 can be quickly disassembled for repair or replacement without disassembling the entire fixture, reducing maintenance difficulty and time costs. Simultaneously, the lamp holder 90 allows for the orderly installation of the indicator lamp 60 and the power supply unit, protecting electrical components from damage and improving the operational stability of the lamp assembly.

[0093] For example, the specific details of testing a full-tooth radiator are as follows:

[0094] The 5G special full-tooth heat sink to be inspected (the number and position of the teeth meet the design requirements) is placed on one side of the front panel 20 of the foolproof inspection fixture, and positioned by the positioning components on the base 10: the edge of the heat sink abuts against the positioning plate 70, restricting its lateral displacement; at the same time, the positioning holes on the heat sink and the positioning pins 80 passing through the front panel 20 are precisely inserted, preventing the heat sink from rotating or translating, and ensuring that the heat sink and the front panel 20 are accurately fitted. At this time, the clearance groove 203 on the front panel 20 precisely avoids the protruding structure on the heat sink, with no structural interference.

[0095] A force perpendicular to the base 10 is applied to push the full-tooth radiator to fit against the front panel 20. During this process, some of the radiator's teeth push against the second conductive block 40 in the through groove 201 of the front panel 20. Since the position of the teeth of the full-tooth radiator is perfectly matched with the arrangement position of some of the second conductive blocks 40, the second conductive block 40 pushed by the teeth moves axially along the through groove 201 towards the first conductive block 30 in the mounting groove 101.

[0096] As the thrust continues, the conductive contact end of the second conductive block 40 gradually approaches the conductive contact end of the first conductive block 30, eventually making full contact with the first conductive block 30. At this point, the series circuit consisting of the first conductive block 30 (connected to the output end of the power supply unit via a wire), the second conductive block 40 (connected to the signal input end of the indicator lamp 60 via a wire), the indicator lamp 60, and the power supply unit is activated. The power supply unit provides operating power to the indicator lamp 60, and the indicator lamp 60 emits an indicator light after being powered on.

[0097] When indicator light 60 illuminates, it indicates that the series circuit is conducting normally and that the number and position of the fins on the heatsink under test meet the full-tooth design requirements. After the test is completed, the force applied to the heatsink is removed, and the return spring 50 between the first conductive block 30 and the second conductive block 40 releases its elastic potential energy, pushing the second conductive block 40 to move in the opposite direction along the through slot 201 and return to its initial position. The inspection fixture can then proceed to the next full-tooth heatsink inspection process.

[0098] For example, the specific details of detecting a radiator with missing teeth are as follows:

[0099] The 5G special toothed heat sink to be inspected (with at least one missing tooth and fewer teeth than required for a full tooth design) is placed on one side of the front panel 20 of the foolproof inspection fixture. It is also positioned by the positioning components: the positioning plate 70 abuts against the edge of the heat sink and the positioning pin 80 is inserted into the positioning hole of the heat sink to ensure that the heat sink fits in the same position as the reference during the full tooth inspection. The clearance groove 203 of the front panel 20 avoids the existing teeth of the heat sink, so there is no interference problem.

[0100] A force perpendicular to the base 10 is applied to push the finned radiator to fit against the front panel 20. Due to the missing fins on the radiator, the second conductive block 40 in the through slot 201 of the front panel 20 corresponding to the missing fins is not pushed by any fins and remains in its initial position, unable to move towards the first conductive block 30. Only the existing fins can push the second conductive block 40 at the corresponding position, causing it to move towards and make contact with the first conductive block 30. However, because the second conductive block 40 corresponding to the missing fins does not make contact with the first conductive block 30, the series circuit cannot form a complete circuit (the series circuit requires all the second conductive blocks 40 at the corresponding full-fin positions to make contact with the first conductive block 30 to conduct, or the circuit is directly cut off if the second conductive block 40 at the position corresponding to the missing fins does not make contact).

[0101] Even if part of the second conductive block 40 is in contact with the first conductive block 30, the current from the power supply unit cannot be transmitted to the indicator light 60 through the complete circuit because of the circuit break. The indicator light 60 is always in a non-powered state and does not emit indicator light.

[0102] If indicator light 60 does not illuminate, it indicates that the series circuit is not conducting, and the heat sink under inspection has missing teeth, which meets the design requirements for a missing tooth. After the thrust is removed, the return spring 50 pushes the moved second conductive block 40 back to its initial position, and the inspection fixture can be used for the next inspection of a heat sink with missing or full teeth.
