[0023] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 7 As shown, this utility model provides a floating plate-to-plate connector assembly, which includes a first connector 100 and a second connector 500 that can be floatingly inserted into the first connector 100. The first connector 100 includes a first insulating body 1 and a plurality of first conductive terminals 2 fixed in the first insulating body 1. The first insulating body 1 includes a fixed body 11 and a movable body 12 that can be floatingly connected to the fixed body 11. Each first conductive terminal 2 includes a floating portion 21 fixed in the fixed body 11 and a fixed portion 23 fixed in the movable body 12. The fixed portion 23 has a flat contact portion 231 that contacts the second connector 500. The fixed portion 23 is detachably connected to the floating portion 21 and can move relative to the fixed body 11 under the action of the floating portion 21.

[0025] The floating board-to-board connector assembly of this utility model achieves floating connection by setting the first conductive terminal 2 as a detachably connectable floating part 21 and fixed part 23, thus forming a segmented terminal structure. This enables the floating board-to-board connector assembly to float in the horizontal and vertical directions with limited floating, thereby improving product reliability. The segmented terminal structure also reduces manufacturing difficulty and gives the floating board-to-board connector assembly better elasticity and fault tolerance, allowing for slight offset of the connector in various directions. Users can more easily operate the docking between the first and second connectors 100 and 500 without complete and precise alignment, improving operational convenience while maintaining a reliable electrical connection.

[0026] Furthermore, by setting the first conductive terminal 2 as a segmented terminal structure, it is possible to accommodate positioning errors of multiple products during mating and improve the reliability of the products under complex conditions such as vibration.

[0027] In one embodiment of the present invention, the floating part 21 includes a first holding section 211 fixed within the fixed body 11 and a connecting section 212 connected to the fixed part 23. The floating part 21 also has an elastic section 213 formed by bending from the first holding section. The elastic section 213 connects the connecting section 212 and the first holding section 211. The elastic section 213 is suspended to be elastic, thereby enabling the end of the elastic section 213 connected to the connecting section 212 to move in multiple directions.

[0028] The floating portion 21 also has a first solder foot 214 formed by bending from the first retaining section 211. The first solder foot 214 is exposed on the underside of the first insulating body 1 for soldering to a circuit board (not shown). The first solder foot 214 and the elastic section 213 are respectively located on both sides of the first retaining section 211 in the vertical direction, and the extending direction of the elastic section 213 is opposite to the extending direction of the first solder foot 214. The elastic sections 213 of the two rows of first conductive terminals 2 extend from their first retaining sections 211 in a direction toward each other, so that the distance between the first retaining sections 211 of the two rows of first conductive terminals 2 is greater than the distance between their connecting sections 212.

[0029] The fixing portion 23 further includes a second retaining section 232 fixed to the movable body 12, the second retaining section 232 abutting against the connecting section 212. In this embodiment, the fixing portion 23 is not only stably held in the movable body 12 by the second retaining section 232, but also achieves mechanical and electrical connection with the connecting section 212 by the second retaining section 232.

[0030] The second retaining segment 232 is fixed to the movable body 12 on both sides in the first direction and abuts against the connecting segment 212 on one side in the second direction, the second direction being perpendicular to the first direction. Thus, in this embodiment, by using the second retaining segment 232 on both sides in the first direction to maintain its position with the movable body 12, and by using the second retaining segment 232 on one side in the second direction to achieve connection with the connecting segment 212, not only can the fixed part 23 be stably held within the movable body 12, but it can also be reliably connected to the floating part 21, thereby achieving floating transmission.

[0031] At least one of the connecting segment 212 and the second retaining segment 232 is provided with a protrusion 2321 that abuts against the other. In this embodiment, the protrusion 2321 is provided on the side of the second retaining segment 232 facing the connecting segment 212 and is an elongated strip extending in the vertical direction. In other embodiments, the protrusion 2321 may also be provided on the connecting segment 212 and protrude towards the second retaining segment 232. In other embodiments, the protrusion 2321 may also be provided as one or more protrusion-like structures. Thus, in this embodiment, by providing the protrusion 2321, the connecting segment 212 and the second retaining segment 232 can be more tightly fixed within the movable body 12, thereby reliably transmitting the movement of the connecting segment 212 to the second retaining segment 232 and the movable body 12.

[0032] The second retaining section 232 is provided with a first interference portion 2322 and a second interference portion 2323 spaced apart in the height direction. The first and second interference portions 2322 and 2323 are respectively located on the upper and lower sides of the protrusion 2321. In this embodiment, the second retaining section 232 is reliably fixed in the movable body 12 on both the upper and lower sides of the protrusion 2321, and a reliable connection between the second retaining section 232 and the connecting section 212 is achieved through the protrusion 2321 located in the middle, thereby realizing follow-up.

[0033] The movable body 12 includes a main body 121 located on the upper side and an extension 123 located on the lower side. The extension 123 is movably connected to the fixed body 11. The main body 121 is suspended in the air and disposed inside the fixed body 11. The fixed body 11 has a pair of end walls 112 disposed opposite to each other in a first direction and a pair of limiting walls 113 disposed opposite to each other in a second direction. The pair of end walls 112 and limiting walls 113 are connected to form a receiving space 110 for the main body 121 to move within it.

[0034] The main body 121 is provided with a receiving groove 1212 extending in the vertical direction to receive and fix the second retaining section 232. The connecting section 212 is inserted upward into the receiving groove 1212 and abuts against the second retaining section 232 in the receiving groove 1212.

[0035] The main body 121 is provided with a docking space 1210 that is open upward for insertion of the second connector 500. The contact portion 231 extends straight upward from the second retaining section 232, and two rows of the contact portions 231 are exposed in the docking space 1210 and are arranged face to face.

[0036] The fixing portion 23 also has a limiting section 234 formed by bending from the bottom end of the second retaining section 232. The limiting section 234 is located below the main body 121 and abuts against the bottom end of the main body 121. Thus, by providing a limiting section 234 extending in the second direction at the bottom end of the fixing portion 23, the position of the fixing portion 23 in the vertical direction is restricted by the limiting section 234, thereby stopping and limiting the fixing portion 23 when it is assembled to a predetermined position of the movable body 12.

[0037] In one embodiment of the present invention, the first connector 100 further has a pair of fixing members 3 installed on both sides of the insulating body 1. The fixing members 3 are inserted into both sides of the fixing body 11 in a first direction to fix the fixing body 11 onto the circuit board.

[0038] like Figure 7As shown, in one embodiment of the present invention, the second connector 500 includes a second insulating body 5 and a plurality of second conductive terminals 6 fixed within the second insulating body 5. The second conductive terminal 6 has a holding portion 61 fixed within the second insulating body 5, a pair of contact arms 62 extending downward from the holding portion 61, and a second solder foot 63 extending from the holding portion 61 along a second direction. The pair of contact arms 62 are cantilevered and arranged side by side in the second direction. Each contact arm 62 can move elastically in the second direction under the pressure of the first conductive terminal 2, thereby achieving better electrical contact with the first conductive terminal 2.

[0039] The second connector 500 is inserted into the mating space 1210 of the first connector 100, and the second conductive terminal 6 contacts the contact portion 231 on the fixing portion 23 of the first conductive terminal 2 within the mating space 1210.

[0040] In the pair of contact arms 62, one contact arm 62 extends downward beyond the other contact arm 62 to form a pair of contact points with a height difference, thereby effectively increasing the number of electrical contact points and achieving more stable electrical conductivity.

[0041] Therefore, in summary, the floating plate-to-plate electrical connector assembly of this utility model, by configuring the first conductive terminal 2 of the first connector 100 to include a floating portion 21 fixed within the fixed body 11 and a fixed portion 23 fixed within the movable body 12, wherein the fixed portion 23 has a flat contact portion 231 for contacting the second connector 500, and the fixed portion 23 is detachably connected to the floating portion 21 and can move relative to the fixed body 11 under the action of the floating portion 21, gives the first connector 100 good elasticity and fault tolerance, allowing the second connector 500 to move freely. The 500's limited floating in both horizontal and vertical directions accommodates positioning errors during mating of multiple products, improving product reliability under complex conditions such as vibration. While enhancing operational convenience, it maintains reliable electrical connections. In some fields, such as automotive electronics, aerospace, and industrial control, connectors are easily affected by external forces. The floating plate-to-plate electrical connector combination can also mitigate the impact of external stress on the connector combination, reduce wear and damage, extend the service life of the entire system, and improve reliability. Furthermore, the segmented first conductive terminal 2 simplifies the structure of the first connector 100, making assembly easier and reducing the manufacturing difficulty of the product.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0043] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application 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 application without departing from the spirit and scope of the technical solutions of this application.
