Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a detection card holder. Background Technology

[0002] In the field of medical diagnostics, the lipid testing card holder is a key connecting component, and its performance directly affects the accuracy of test results and the reliability of the equipment. Traditional card holders use a straight spring-loaded structure, which is prone to poor contact under high-frequency insertion and removal and vibration environments, leading to signal transmission interruptions or fluctuations.

[0003] For example, in the hundreds of operations performed daily in medical institutions, shrapnel gradually loses its elasticity due to mechanical fatigue, resulting in decreased contact pressure and distorted test data. Such malfunctions not only affect diagnostic efficiency but may also delay patient treatment due to misdiagnosis.

[0004] Especially in portable blood lipid testing devices, space constraints exacerbate the difficulty of aligning the spring and sensor, further deteriorating contact stability.

[0005] Existing solutions often rely on manual calibration or periodic component replacement, failing to fundamentally address the contact impedance variations caused by vibration and insertion / removal. Therefore, a novel structural design is urgently needed to ensure constant contact pressure and reliable signal transmission over long-term use, thereby improving the overall performance of medical devices. Summary of the Invention

[0011] Furthermore, the channel matches the cross-sectional shape of the wedge.

[0012] Furthermore, the window is positioned directly above the end bullet piece.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Sensor installation and positioning issues: The design of straight-lined windows and chamfered openings solves the guidance and positioning problems when inserting the sensor; the chamfered opening design can prevent the sensor from being misaligned or stuck when inserted.

Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0024] like Figure 1-7 As shown, this utility model provides a detection card holder, including a circuit board 1, wherein the circuit board 1 is provided with a through hole 11 and a through hole 12, and further includes: The housing 2 is disposed above the circuit board 1, and the housing 2 has a cavity 21 for accommodating the sensor 3. Multiple end-capsule pieces 4 are arranged in a straight line and snapped into the cavity 21; Sensor 3 is disposed in the cavity 21 and abuts against the end bullet piece 4; The cavity 21 has windows 22 arranged in a straight line above it, and the side of the cavity 21 has chamfered openings 23 for inserting the sensor 3. Each of the aforementioned end bullet pieces 4 includes a bullet piece base 41, the upper end of which is connected to a forward-bent bullet piece welding part 42, and the lower end of which is connected to a backward-bent bullet piece abutment part 43; the bent end of the bullet piece abutment part 43 faces the direction of the chamfered opening 23.

[0025] Sensor 3 installation and positioning problem: The design of straight-line arranged windows 22 and chamfered openings 23 solves the guidance and positioning problem when inserting sensor 3; the chamfered openings 23 design can prevent sensor 3 from being misaligned or stuck when inserted.

[0026] Electrical connection reliability issues: The linear arrangement of the end springs 4 ensures consistency of the contact points with the sensor 3; the J-shaped spring abutment part 43 provides stable elastic contact pressure; the slide-type spring welding part 42 enhances the welding reliability with the circuit board 1.

[0027] Structural compactness: The integrated design of the housing 2 cavity 21 and the circuit board 1 saves space; the matching design of the wedge 5 and the channel 24 enhances structural stability.

[0028] Production assembly efficiency issues: The standardized linear arrangement of the end spring pieces 4 facilitates automated assembly; the alignment of the window 22 with the spring pieces facilitates quality inspection.

[0029] Heat dissipation and signal transmission issues: The 22-window design is conducive to heat dissipation; the linear arrangement of spring contacts optimizes the signal transmission path.

[0030] Mechanical strength issues: The design of the wedge 5 embedded in the channel 24 enhances the overall structural strength; the bending angle between the spring base 41 and the welded part optimizes the stress distribution.

[0031] Through the aforementioned structural innovations, this technical solution achieves precise positioning of sensor 3 installation, reliable and stable electrical connection, and a compact and efficient overall structure, making it particularly suitable for electronic devices requiring high-precision detection.

[0032] See Figure 4 The spring-loaded welding part 42 has a slide-shaped structure and is welded to the circuit board 1.

[0033] See Figure 4The spring contact part 43 has a J-shaped structure. The curved part of the J-shaped structure can provide progressive elastic deformation. During the insertion and removal process, it absorbs mechanical impact through geometric deformation, reduces instantaneous pressure fluctuations caused by vibration or insertion and removal, and ensures stable contact pressure with the sensor 3 contact point. Traditional straight springs are prone to plastic deformation due to stress concentration after repeated insertion and removal, while the arc design of the J-shaped spring can disperse stress distribution, reduce the risk of local fatigue, and significantly improve the durability of the spring.

[0034] See Figure 3 The housing 2 has channels 24 on both sides of the window 22. Wedges 5 are provided in the channels 24. The wedges 5 are fully embedded in the channels 24 and extend to the first through hole 11. The wedges 5 are embedded in the channels 24 through an interference fit or a snap-fit ​​structure, forming a mechanical reinforcement of the housing 2. This can effectively suppress the deformation of the window 22 area caused by frequent insertion and removal or external vibration, and avoid poor contact problems caused by loosening of the housing 2. The wedges 5 extending to the first through hole 11 can further disperse stress, prevent the edge of the through hole from cracking due to long-term stress, and improve the overall structural durability.

[0035] See Figure 3 The channel 24 matches the cross-sectional shape of the wedge 5. Through the asymmetrical or specific geometric cross-sectional design, it is ensured that the wedge 5 can only be embedded in the channel 24 in a single direction, avoiding failure of the card holder structure due to assembly errors.

[0036] See Figure 1 The window 22 is located directly above the end spring piece 4. In the blood lipid detection card holder, the window 22 faces the spring piece position, which makes it easy to visually inspect the contact status of the spring piece, such as oxidation, deformation or contamination. The cause of the fault can be quickly determined without disassembly. During maintenance, the spring piece or contact can be cleaned directly through the window 22, avoiding frequent disassembly of the housing 2 and improving the availability of the equipment. The window 22 serves as a heat dissipation channel 24, which can accelerate the dissipation of heat generated by the current passing through the spring, and prevent the spring from losing its elasticity or increasing its contact resistance due to high temperature. It is especially suitable for high-frequency detection scenarios. In humid environments, the window 22 design helps air circulation and reduces the risk of short circuit caused by condensation accumulation. The correspondence between the window 22 and the spring can serve as a visual positioning reference, helping the operator to accurately insert the detection card and avoid excessive bending or poor contact of the spring due to misalignment.
