Description

Technical Field

[0001] The utility model is applied to the technical field of B2B connector testing, and in particular relates to a B2B connector adaptive testing structure. Background Art

[0002] In the current 3C industry, electronic products are becoming increasingly sophisticated and intelligent, integrating more and more functions. B2B connectors are often used to connect components within these products. Therefore, during the product production process, B2B connectors must undergo various performance tests to ensure they meet factory requirements. During B2B connector testing, the connector is typically initially positioned and secured to a Nest locating block. Testing is then performed using a B2B test pin adapter. This method is suitable for conventional B2B connectors, but for connectors with unusual shapes and sizes, such as those with multiple deflections, these test fixtures are unable to meet the testing requirements. Furthermore, during the pin insertion process, due to factory tolerances for each B2B connector, the deflection angles vary, leading to some offset during the B2B connector positioning process. Furthermore, during testing, the connector is typically secured at the B2B end, preventing floating. Excessive pressure from the pin block can cause the B2B connector to be pulled in the Nest locating block, potentially causing deformation and crushing. If a B2B connector adaptive test structure with a simple structure, easy-to-operate flip-up structure, accurate positioning, strong applicability, and a multi-directional floating design to reduce pin insertion errors can be designed, the above problems can be solved.

[0023] like Figures 1 to 9 As shown, in this embodiment, the utility model includes a base plate 1, a test needle block module 2 and a floating module 3, the floating module 3 includes a floating mounting plate 31, a flip cover 32 and a floating plate 33, one side of the flip cover 32 is hinged to one side of the floating mounting plate 31 through a rotating shaft 4, the upper end face of the flip cover 32 is provided with a floating plate profiling groove 34, the floating plate 33 cooperates with the floating plate profiling groove 34, the lower end face of the floating plate 33 is provided with a B2B profiling groove 35, the connecting end of the B2B connector 5 is connected to the floating plate 33 through the B2B profiling groove 35, the floating plate 33 is floatingly connected to the flip cover 32 through a number of equal height screws 6 and a number of floating springs, the probe end of the test needle block module 2 cooperates with the connecting end of the B2B connector 5 on the floating plate 33. It can be seen that the flip cover 32 and the floating mounting plate 31 cooperate to realize the opening and closing of the clamp, and the B2B connector 5 is arranged at the lower end of the floating plate 33. The connection end of the B2B connector 5 is facing upward in the pressed state, and the positioning is precise, so that the test needle block module 2 can be pressed down and docked. During the needle insertion process, the other side of the B2B connector 5 is in contact with the floating mounting plate 31, and the B2B connector 5 will not be separated from the B2B contoured groove 35. After the test is completed, the flip cover 32 can be opened for replacement. The structure is simple and the operation is convenient.

[0024] like Figure 2 and Figure 7As shown, in this embodiment, the test needle block module 2 includes a needle block support plate 21 and a needle block 22. The upper end surface of the needle block support plate 21 is provided with a needle block limiting groove 23. The needle block 22 is connected to the needle block limiting groove 23 by a plurality of locking screws 24. The needle block limiting groove 23 is provided with a needle block through-hole 25. The probe end of the needle block 22 mates with the connecting end of the B2B connector 5 on the floating plate 33 through the needle block through-hole 25. Thus, the needle block 22 is fixed to the external lifting mechanism or manipulator via the needle block support plate 21. The needle block 22 and the needle block support plate 21 are fixedly connected. The external lifting mechanism or manipulator drives the needle block 22 to connect and conduct with the B2B connector 5 on the floating plate 33.

[0025] like Figure 6 and Figure 7 As shown, in this embodiment, the lower end surface of the needle block support plate 21 is provided with a plurality of positioning guide shafts 7, and the floating plate 33 is provided with a plurality of positioning guide sleeves 8. The plurality of positioning guide shafts 7 and the plurality of positioning guide sleeves 8 cooperate with each other. As can be seen, during the descent of the needle 22, the plurality of positioning guide shafts 7 and the plurality of positioning guide sleeves 8 cooperate to achieve preliminary positioning, making the downward positioning process more accurate.

[0026] like Figure 2 and Figure 5 As shown, in this embodiment, the base plate 1 is provided with a floating mounting groove 9, and the floating mounting plate 31 is limitedly engaged with the floating mounting groove 9. Thus, it can be seen that the floating mounting groove 9 enables the floating mounting plate 31 to be stably mounted on the base plate 1 without deviation.

[0027] like Figures 1 to 4 As shown, in this embodiment, a flip handle 10 is provided on one side of the flip cover 32, and the middle portion of the flip handle 10 is rotatably engaged with the rotating shaft 4. Thus, by turning the flip handle 10 to open the flip cover 32, it is possible to avoid accidental contact when directly opening the flip cover 32, which may cause the product to shift and fall off.

[0028] like Figures 1 to 5 As shown, in this embodiment, a handle movable groove 11 is provided on the side of the floating mounting groove 9 corresponding to the flip cover handle 10, and the flip cover handle 10 cooperates with the handle movable groove 11. Thus, when the base plate 1 is placed on an operating machine, the flip cover 32 can be opened and closed at the lower end of the base plate 1, allowing both hands to simultaneously open the cover and change materials without interfering with each other, making operation more efficient.

[0029] like Figure 2 and Figure 4As shown, in this embodiment, a plurality of torsion springs 12 are further provided in the middle of the rotating shaft 4, and the plurality of torsion springs 12 respectively cooperate with the flip cover 32 and the floating mounting plate 31. Thus, it can be seen that the plurality of torsion springs 12 provide the flip cover 32 with the function of loading and restoring and providing downward pressure.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, a pressure-prevention gap 13 is provided on one side of the needle block limiting groove 23 and the needle block support plate 21. The pressure-prevention gap 13 cooperates with the deflected end of the B2B connector 5. Thus, the pressure-prevention gap 13 can adapt to a variety of B2B connectors. During the downward pressing process, the deflected portion of the B2B connector 5 passes through the pressure-prevention gap 13, preventing the needle block 22 from pressing on the deflected portion and causing damage to the B2B connector 5.

[0031] like Figure 9 As shown, in this embodiment, the floating plate 33 and the floating plate contoured groove 34 are provided with floating allowances in both the X-axis and Y-axis directions. This allows the floating plate 33 and the flip cover 32 to have a 0.2 cm planar floating allowance in both the X-axis and Y-axis directions. This ensures that the floating plate 33 can achieve adaptive adjustment in both the X-axis and Y-axis directions during the downward pressure of the needle block 22. Furthermore, the plurality of contour screws 6 and the floating spring enable floating in the Z-axis direction, achieving multi-directional linkage to prevent overpressure caused by inaccurate positioning and achieve adaptive adjustment.

[0032] The working principle of the utility model is as follows: before the equipment is started, the flip cover handle 10 is driven to rotate the flip cover 32 around the rotating shaft 4, the B2B connector 5 to be tested is installed at the lower end of the floating plate 33, the connection end of the B2B connector 5 is limited by the B2B profiling groove 35 to realize product positioning, the flip cover handle 10 is released, the flip cover 32 is restored to the compressed state, the needle block 22 is lowered, and the plurality of positioning guide shafts 7 are matched with the plurality of positioning guide sleeves 8 to realize preliminary positioning, and the probe end of the needle block 22 is aligned with the positioning guide sleeve 8. The connecting end of the B2B connector 5 contacts and continues to press down. The edge of the probe end of the needle block 22 contacts the edge of the connecting end of the B2B connector 5 and pushes the floating plate as a whole to adaptively adjust in multiple directions to achieve precise positioning. Continue to press down to make the needle block 22 tightly pressed against the B2B connector 5. After completing the power-on test, the needle block 22 rises, drives the flip cover handle 10 to open the flip cover 32, replaces the B2B connector 5 to be tested, and repeats the above steps to achieve the adaptive adjustment test of the B2B connector.

[0033] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
