Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a floating board-to-board connector that avoids end-face gaps. Background Technology

[0002] Floating board-to-board connectors are a type of electromechanical interconnect. With the help of the floating structure inside the connector, damage to various components on the PCB can be effectively prevented. In particular, it eliminates the misalignment in the "x" and "y" directions during PCB installation and assembly, and can provide a certain space tolerance between boards, thereby ensuring the stability and reliability of the connector.

[0003] The connector head has a certain floating capability, allowing it to float freely up and down and left and right. This enables the connector head to adaptively adjust its position within a certain range between the connecting boards, thus achieving a precise connection between the boards. However, when the upper and lower connecting components are connected together, the floating structure inside the connector may cause a gap between the upper and lower connector end faces, and may also result in circuit blockage or circuit failure. Misalignment is also prone to occur during installation, thus affecting the normal use of the connector.

[0004] To address this, we propose a floating board-to-board connector that avoids end-face gaps. Utility Model Content

[0005] To overcome the aforementioned drawbacks, this invention provides a floating plate-to-plate connector that avoids end-face gaps.

[0006] The technical solution is as follows: A floating board-to-board connector that avoids end-face gaps includes a first connector, a fixing block, a connecting block, a locking block, a first spring, and screws. The first connector is inserted into a second connector. Fixing blocks are fixedly connected to both sides of the first connector. Connecting blocks are fixedly connected to both sides of the second connector. Locking blocks are slidably connected to the lower side of each connecting block. A first spring is connected between each locking block and the connecting block on the same side. Each locking block engages with the fixing block on the same side. The four corners of the first connector and the second connector are tightened by four screw threads.

[0007] More preferably, it also includes guide cylinders and guide posts. Guide cylinders are symmetrically connected to both sides of the top of the first connector, and guide posts are symmetrically connected to both sides of the bottom of the second connector. The guide posts slide in cooperation with the guide cylinders on the same side.

[0008] More preferably, it also includes a second spring and a buffer block. The upper side of each guide post is slidably connected to a buffer block. The connection between the buffer block and the guide post is damped. The buffer block and the guide post on the same side are connected to a second spring. The buffer block can buffer the guide post when it contacts the guide cylinder.

[0009] More preferably, it also includes a threaded rod and a rotating block, with threaded rods snapped into both sides of the second connector, and rotating blocks connected to the middle of each threaded rod. Threaded holes are opened on both sides of the first connector, and the threaded rods are threadedly engaged with the threaded holes.

[0010] More preferably, the upper wall of the fixing block is inclined, which can contact the locking block and thus push the locking block to move outward.

[0011] More preferably, the guide post is hollow inside, and screws can be inserted into the guide post and threadedly fixed to the second connector through the guide post.

[0012] The beneficial effects of this utility model after adopting the above structure are as follows:

[0013] 1. By engaging the locking block and the fixing block, the first connector and the second connector can be fixed, eliminating any gap between them, preventing shaking when the floating structure floats, and improving the stability between the first connector and the second connector;

[0014] 2. The guide post is inserted into the guide cylinder to guide the insertion of the first connector and the second connector. The screw is also inserted into the guide post to guide the screw.

[0015] 3. The addition of threaded rod and threaded hole threaded fit can further improve the stability between the first connector and the second connector, while the buffer block buffers the guide post and can prevent excessive force from damaging the guide post when it is inserted into the guide cylinder.

Detailed Implementation

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example: A floating board-to-board connector that avoids end-face gaps, such as... Figures 1-4 As shown, it includes a first connector 1, a fixing block 2, a connecting block 6, a locking block 7, a first spring 8, and screws 14. The first connector 1 is inserted into the second connector 5. Fixing blocks 2 are fixedly connected to the front and rear side walls of the first connector 1. Connecting blocks 6 are fixedly connected to the front and rear side walls of the second connector 5. Locking blocks 7 are slidably connected to the lower side of the connecting blocks 6. First springs 8 are connected between the left and right sides of the locking blocks 7 and the connecting blocks 6 on the same side. The locking blocks 7 are engaged with the fixing blocks 2 on the same side. The upper wall of the fixing block 2 is inclined and can contact the locking blocks 7, thereby pushing the locking blocks 7 to move outward. The four corners of the first connector 1 and the second connector 5 are tightened by four screws 14.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a guide cylinder 3 and a guide post 9. The top left and right sides of the first connector 1 are symmetrically connected with the guide cylinder 3, and the bottom left and right sides of the second connector 5 are symmetrically connected with the guide post 9. The guide post 9 slides with the guide cylinder 3 on the same side. The guide post 9 is aligned with the guide cylinder 3 and can slide into the guide cylinder 3 to guide the insertion of the first connector 1 and the second connector 5. The guide post 9 is hollow inside, and the screw 14 can be inserted into the guide post 9 and threadedly fixed to the second connector 5 through the guidance of the guide post 9.

[0025] like Figure 4 and Figure 5 As shown, it also includes a second spring 10 and a buffer block 11. The upper side of the guide post 9 is slidably connected to the buffer block 11. The connection between the buffer block 11 and the guide post 9 is damped. The second spring 10 is connected between the buffer block 11 and the guide post 9 on the same side. The buffer block 11 moves with the guide post 9 and is fitted into the guide cylinder 3. The contact between the buffer block 11 and the guide cylinder 3 can buffer the guide post 9.

[0026] like Figure 1 and Figure 4 As shown, it also includes a threaded rod 12 and a rotating block 13. The threaded rod 12 is snapped into both the left and right sides of the second connector 5. The rotating block 13 is connected to the middle of the threaded rod 12. The threaded holes 4 are opened on both the left and right sides of the first connector 1. The threaded rod 12 is threaded into the threaded holes 4.

[0027] When connecting the first connector 1 and the second connector 5, insert the screw 14 into the guide post 9, hold the second connector 5, align the guide post 9 with the guide cylinder 3, and insert the guide post 9 into the guide cylinder 3. The second connector 5 will then be close to the first connector 1, and the threaded rod 12 on the second connector 5 will also be close to the threaded hole 4. When the locking block 7 contacts the inclined surface of the fixing block 2, the threaded rod 12 contacts the threaded hole 4. Simultaneously, the buffer block 11 contacts the guide cylinder 3. The operator rotates the rotating block 13, causing the threaded rod 12 to rotate. The top cap pushes the second connector 5 downward, causing the threaded rod 12 to screw into the threaded hole 4. The downward movement of the second connector 5 compresses the buffer block 11, compressing the second spring 10. The buffer block 11 acts as a buffer for the guide post 9. Simultaneously, the locking block 7 moves downward, causing the fixing block 2 to push the locking block 7 outward. The first spring 8 is compressed. After the locking block 7 passes the fixing block 2, it moves inward to reset under the reset action of the first spring 8, thus locking the fixing block 2. After tightening the threaded rod 12, tools can be used to tighten the screw 14, making the screw... 14 engages with the first connector 1 threadedly, thereby connecting and fixing the first connector 1 and the second connector 5. Thus, the insertion is completed. The fixing block 2 and the locking block 7 are fixed. When the floating structure inside the second connector 5 floats, there is no gap between the end faces of the first connector 1 and the second connector 5, and it is not easy to vibrate. When separating the first connector 1 and the second connector 5, loosen the screw 14 so that it no longer fixes the first connector 1, and reverse the rotating block 13 to drive the threaded rod 12 to reverse, disengaging the threaded rod 12 from the threaded hole 4. The threaded rod 12 is in a loose state on the first connector 1. Then, pull the locking block 7 outward to compress the first spring 8. After the locking block 7 no longer locks the fixing block 2, the first connector 1 can be pulled upward to separate the first connector 1 and the second connector 5. Then, release the locking block 7 so that the locking block 7 moves inward to reset under the reset action of the first spring 8. After the first connector 1 is released, it moves upward with the guide post 9 to disengage from the guide cylinder 3. The buffer block 11 is no longer subjected to the squeezing force and will rebound to reset under the reset action of the second spring 10.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
