Description

Technical Field

[0001] This utility model belongs to the field of connector testing technology, and in particular relates to a floating board insertion mechanism. Background Technology

[0002] In modern electronics manufacturing, various printed circuit boards, such as computer motherboards and automotive control boards, widely use high-speed serial bus standards (such as PCI-e) slot connectors as key interfaces. To ensure product quality, functional testing of these slots during the manufacturing process is an essential step. A common testing method is to directly insert input / output cards (IO cards) with power supply and signal transmission testing functions into the slot under test to simulate real-world usage scenarios and verify the functional integrity of the slot.

[0003] However, this direct insertion and removal testing method for I / O cards has significant drawbacks in practice. Firstly, in mass production environments, the same I / O card often needs to be frequently inserted and removed into multiple slots under test for repeated testing. This direct, rigid, repeated insertion and removal operation easily causes physical wear and damage to the I / O card's gold fingers. This not only significantly shortens the I / O card's lifespan and increases testing costs, but may also lead to unstable test signals or distorted test results. Secondly, the slots under test themselves also face the risk of damage. During rigid insertion and removal, improper force may cause deformation or damage to the precision contacts inside the slot, thus introducing new defective products.

[0004] Therefore, there is an urgent need for a floating board insertion mechanism that can avoid wear and tear on the I / O card. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a floating board insertion mechanism. This mechanism effectively avoids direct contact and wear between the I / O card and the slot under test by using an adapter board. It has floating adjustment capability, reduces the risk of slot damage caused by forced insertion and removal, improves testing efficiency, reduces maintenance costs, and ensures testing reliability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A floating board insertion mechanism, comprising: Mounting block, the mounting block is used to mount and fix to the upper needle plate of the fixture, the mounting block is provided with a movable groove; A floating block, which is located below the mounting block and can float relative to the mounting block; An adapter board is mounted on the floating block and fixed relative to the floating block. The upper end of the adapter board passes through the movable slot and is positioned above the mounting block. The adapter board is provided with an adapter slot. The lower edge of the adapter board is provided with a plug-in part that is connected to the adapter slot for wiring. The plug-in part is located below the floating block and is used to connect to the slot to be tested. An I / O card that can be detachably inserted into the adapter slot is used to implement testing functions.

[0007] Furthermore, the adapter card includes an adapter card fixing plate and an adapter card detachably installed in the adapter card fixing plate. The adapter card fixing plate is installed on the floating block, the adapter slot is provided on the adapter card, and the plug-in part is provided at the lower edge of the adapter card.

[0008] Furthermore, the adapter card fixing plate includes a support plate and a clamping plate detachably mounted on the support plate, the adapter card is clamped between the support plate and the clamping plate, and the insertion portion is exposed at the lower ends of the support plate and the clamping plate.

[0009] Furthermore, the upper end of the clamping plate is provided with a clearance groove, and the adapter slot on the adapter card is exposed to the side of the clamping plate through the clearance groove.

[0010] Furthermore, the IO card inserted into the adapter slot is parallel to the adapter card.

[0011] Furthermore, the support plate and the clamping plate are fixed together by screws.

[0012] Furthermore, the floating block is provided with a fixed groove corresponding to the movable groove, and the adapter plate is vertically installed and fixed in the fixed groove.

[0013] Furthermore, the upper surface of the floating block is provided with a plurality of first spring grooves, and the lower surface of the mounting block is provided with a plurality of second spring grooves. The first spring grooves and the second spring grooves correspond one-to-one, and a floating spring is installed between the first spring grooves and the second spring grooves.

[0015] Furthermore, the mounting block is provided with adjustable fixing blocks at both ends, and the mounting block is mounted and fixed to the upper needle plate of the fixture through the adjustable fixing blocks.

[0016] The beneficial effects of this utility model are: This invention achieves physical isolation between the I / O card and the slot under test by setting a floating block and an adapter board. By allowing the floating block to float relative to the mounting block, the insertion part can connect to the slot under test in a floating manner, avoiding damage to the slot under test caused by rigid insertion and removal. The adapter board is designed as a detachable adapter card fixing plate and adapter card, facilitating individual replacement of the adapter card. The structure of the adapter card being detachably held by the support plate and clamping plate facilitates quick installation, removal, or replacement of the adapter card. The maximum floating stroke of the floating block is limited by the use of equal-height screws.

[0022] See appendix Figure 1 To be continued Figure 5 The figure shows a specific embodiment of the floating board insertion mechanism provided by this utility model.

[0023] See appendix Figure 1 The floating board insertion mechanism includes: Mounting block 1 is used to mount and fix it to the upper needle plate of the fixture. Mounting block 1 is provided with a movable groove 110. Floating block 2 is located below mounting block 1 and can float relative to mounting block 1; An adapter board 3 is mounted on the floating block 2 and fixed relative to the floating block 2. The upper end of the adapter board 3 passes through the movable groove 110 and is positioned above the mounting block 1. The adapter board 3 is provided with an adapter slot 321. The lower edge of the adapter board 3 is provided with a plug part 322 that is connected to the adapter slot 321 for wiring. The plug part 322 is located below the floating block 2 and is used to connect to the slot 7 to be tested. The IO card 4 is detachably inserted into the adapter slot 321 for implementing test functions.

[0024] See appendix Figure 1 In the above embodiment, the mounting block 1 is rectangular and horizontally arranged. The movable groove 110 is rectangular and located in the middle of the mounting block 1, penetrating vertically through the mounting block 1. The floating structure of the floating block 2 allows the floating block 2 to move closer to or further away from the mounting block 1 below it. The adapter plate 3 is vertically arranged, passing through the movable groove 110 and detachably fixed to the floating block 2. In use, the mounting block 1 is fixed to the upper needle plate of the external fixture, and the upper mold assembly of the fixture drives the mounting block 1 to move vertically to abut against the slot 7 to be tested. Due to the floating structure of the floating block 2, when the insertion part 322 below the floating block 2 does not abut against the slot 7 to be tested, there is a floating space between the mounting block 1 and the floating block 2. When the insertion part 322 abuts against the slot 7 to be tested and applies pressure to the slot 7, the floating block 2 floats upward toward the mounting block 1. At the same time, the adapter plate 3 moves vertically relative to the mounting block 1 in the movable groove 110. By using a floating connection to the slot under test 7, damage to the slot under test 7 caused by rigid insertion and removal is avoided. The adapter board 3 is used to connect the IO card 4 to the connector 322 of the adapter board 3, achieving physical isolation between the IO card 4 and the slot under test 7. Since the adapter board 3 is a consumable, wear and tear on the IO card 4 is avoided, significantly reducing testing and maintenance costs.

[0025] See appendix Figure 2 and attached Figure 3 In the above embodiment, the adapter board 3 includes an adapter card fixing plate 310 and an adapter card 320 detachably installed within the adapter card fixing plate 310. The adapter card fixing plate 310 is mounted on the floating block 2, the adapter slot 321 is provided on the adapter card 320, and the insertion part 322 is provided on the lower edge of the adapter card 320. In this embodiment, the adapter card 320 can be installed on or removed from the adapter card fixing plate 310, enabling individual replacement of the adapter card 320. This facilitates the replacement of the adapter card 320 as a consumable when the insertion part 322 wears down and affects testing, without having to replace the entire adapter board 3, further reducing maintenance costs caused by adapter card wear.

[0026] See appendix Figure 2 and attached Figure 3 In the above embodiment, the adapter card fixing plate 310 includes a support plate 311 and a clamping plate 312 detachably mounted on the support plate 311. The adapter card 320 is clamped between the support plate 311 and the clamping plate 312, and the insertion part 322 is exposed at the lower end of the support plate 311 and the clamping plate 312. In the embodiment, the support plate 311 and the clamping plate 312 are fixed together by screws. Specifically, the screws pass through the clamping plate 312, the adapter card 320, and the support plate 311 simultaneously. The screw fixation makes the installation of the adapter card 320 more stable and avoids displacement or misalignment during the pressure test.

[0027] See appendix Figure 2 and attached Figure 3 In the above embodiment, the upper end of the clamping plate 312 is provided with a clearance groove 3121, and the adapter slot 321 on the adapter card 320 is exposed to the side of the clamping plate 312 through the clearance groove 3121. In the embodiment, the IO card 4 inserted into the adapter slot 321 is parallel to the adapter card 320, realizing a compact insertion direction, which makes the entire insertion mechanism more space-saving in the height direction, and facilitates integration into the test fixture.

[0028] See appendix Figure 4 and attached Figure 5 In the above embodiment, the floating block 2 is provided with a fixed groove 210 corresponding to the movable groove 110, and the adapter plate 3 is vertically installed and fixed in the fixed groove 210. In the embodiment, the adapter plate 3 is installed in the fixed groove 210, and the side of the floating block 2 is provided with screws that pass through the floating block 2 and are fixed to the adapter plate 3, thereby realizing the fixation between the adapter plate 3 and the floating block 2.

[0029] See appendix Figure 4 and attached Figure 5 In the above embodiment, the upper surface of the floating block 2 is provided with multiple first spring grooves 220, and the lower surface of the mounting block 1 is provided with multiple second spring grooves 120. The first spring grooves 220 and the second spring grooves 120 correspond one-to-one, and a floating spring 5 is installed between the first spring grooves 220 and the second spring grooves 120. In this embodiment, each of the two sides along the length of the floating block 2 is provided with four first spring grooves 220, for a total of eight first spring grooves 220. Correspondingly, the lower surface of the mounting block 1 is also provided with eight second spring grooves 120, achieving stable and controllable elastic floating, effectively absorbing deviations and impacts during the insertion process, and protecting the test slot 7 and the insertion mechanism itself. The first spring grooves 220 and the second spring grooves 120 limit the floating spring 5, preventing unexpected displacement of the floating spring 5. In this embodiment, an equal-height screw 6 connects the floating block 2 and the mounting block 1 to limit the maximum floating stroke of the floating block 2 relative to the mounting block 1.

[0030] See appendix Figure 4 and attached Figure 5 In the above embodiment, the mounting block 1 is provided with adjustable fixing blocks 130 at both ends, and the mounting block 1 is mounted and fixed to the upper needle plate of the fixture through the adjustable fixing blocks 130. In this embodiment, the adjustable fixing block 130 is provided with a waist hole, which can realize a small range of horizontal adjustment, so as to flexibly and finely adjust the mounting block 1 to different positions of the upper needle plate of the fixture, in order to deal with the situation that the insertion part 322 cannot be aligned with the slot 7 to be tested due to processing errors.

[0031] In summary, this embodiment provides a floating board insertion mechanism. By setting the floating block 2 and the adapter board 3, physical isolation between the IO card 4 and the slot under test 7 is achieved. By allowing the floating block 2 to float relative to the mounting block 1, the insertion part 322 can connect to the slot under test 7 in a floating manner, avoiding damage to the slot under test 7 caused by rigid insertion and removal. By designing the adapter board 3 as a detachable adapter card fixing plate 310 and adapter card 320, it is easy to replace the adapter card 320 individually. The detachable support plate 311 and clamping plate 312 facilitate the connection between the adapter card and the slot under test. The structure of the unclamping adapter card 320 facilitates quick installation, disassembly, or replacement of the adapter card 320. By setting the equal-height screws 6, the maximum floating stroke of the floating block 2 is limited. By setting the adjustable fixing block 130, the mounting block 1 can be flexibly and finely adjusted to different positions on the upper needle plate of the fixture. In this embodiment, the adapter card 3 effectively avoids direct contact and wear between the IO card 4 and the slot under test 7, has floating adjustment capability, reduces the risk of slot damage caused by forced insertion and removal, improves testing efficiency, reduces maintenance costs, and ensures testing reliability.

[0032] The embodiments described above are merely one of the preferred embodiments of this utility model.
