[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0040] Example 1

[0041] refer to Figures 1 to 3This embodiment provides a board-to-board connector, including a male seat structure 1 and a female seat structure 2, which are plugged into each other. Specifically, the male seat structure 1 includes a male seat housing 11 and a plurality of male seats 12, and the plurality of male seats 12 are mounted on the male seat housing 11. Specifically, the female seat structure 2 includes a female seat housing 21 and a plurality of female seats 22, and the plurality of female seats 22 are mounted on the female seat housing 21, and each male seat terminal 12 is electrically connected to each female seat terminal 22.

[0042] Furthermore, the female socket terminal 22 is provided with a plurality of gaps 221, which are spaced apart along the width direction of the female socket terminal 22. As one embodiment, the plurality of gaps 221 may be distributed in parallel, and the width of the gaps 221 is smaller than the interval width between the gaps 221.

[0043] The multiple gaps 221 provide deformation space for the female socket terminal 22, so that the female socket terminal 22 can adapt to the deviation of the installation position during installation, and produce corresponding deformation according to the deviation to meet the floating requirements during installation. At the same time, by opening multiple gaps 221 on the female socket terminal 22, the female socket terminal 22 can also carry a larger current to meet the transmission requirements of large currents and achieve efficient transmission. In this example, the female socket terminal can carry a current of 3A.

[0044] Furthermore, the male terminal 12 includes a first contact portion 121 and a first floating portion 122 connected to the first contact portion 121, and the first contact portion 121 includes two contact arms 1211. As one embodiment, the two contact arms 1211 are connected in parallel to one end of the first floating portion 122. It can be understood that the two contact arms 1211 are electrically connected to one female terminal 22. At this time, the first contact portion 121 of the male terminal 12 is formed with two contact positions on the female terminal 22, which can make the signal transmission between the male terminal 12 and the female terminal 22 more stable, especially under high-frequency vibration environment conditions, which can ensure high stability of signal transmission.

[0045] Example 2

[0046] refer to Figures 4 to 7 As a further optimization of Embodiment 1, a plurality of male terminals 12 are arranged in two rows at equal intervals and in a mirror image distribution, and a plurality of female terminals 22 are arranged in two rows at equal intervals and in a mirror image distribution. It can be understood that the number and position of the plurality of male terminals 12 correspond to the number and position of the plurality of female terminals 22, and one male terminal 12 is electrically connected to one female terminal 22.

[0047] As a further optimization, a bent structure 1212 is formed at one end of the contact arm 1211 away from the first floating portion 122, and the bent structure 1212 is used to electrically connect with the female terminal 22. It can be understood that the bend on the bent structure 1212 contacts the female terminal 22 to achieve electrical connection, thereby changing the contact position between the male terminal 12 and the female terminal 22 from a contact surface to a contact point, which can make the transmission of signals or currents more concentrated and more efficient. In addition, the bent structure 1212 has an elongated floating space that can meet the floating requirements during installation, and can produce corresponding deformation according to the deviation of the installation position during installation to achieve a stable connection and ensure the stability of transmission.

[0048] As a further optimization, the female socket terminal 22 includes a second contact portion 222 and a second floating portion 223 connected to the second contact portion, and the second contact portion 222 is used to be electrically connected to the two contact arms 1211. Specifically, the second contact portion 222 is electrically connected to the bending structures 1212 on the two contact arms 1211.

[0049] Specifically, the second floating portion 223 is a U-shaped structure 2231, and a plurality of first bends A are formed at both ends of the U-shaped structure 2231. A rounded bend is formed in the U-shaped structure 2231, which, on the one hand, provides a deformation space for the structures at both ends of the rounded bend, and can meet the floating requirements when the female terminal is installed; on the other hand, it can disperse the stress of the female terminal when floating, so that the female terminal can be restored to its original state in time after the floating ends.

[0050] Furthermore, the angle of the first bend A is an obtuse angle. Setting the angle of the first bend A to an obtuse angle can make the female socket terminal 22 better elongated and extended when floating. By setting multiple first bends A, the female socket terminal 22 can be elongated and extended at different positions, thereby meeting the floating requirements of different installation positions and achieving a better floating effect. In this example, the floating range of the female socket terminal 22 is ±1.0mm.

[0051] In some embodiments, the first floating portion 122 may also be formed with a plurality of second bends B, and the angles of the second bends B are obtuse angles, thereby achieving the same floating effect as the female socket terminal 22 .

[0052] Example 3

[0053] refer to Figures 8 to 10 As a further optimization of Example 1, the male socket housing 11 includes a male socket rubber core 111, and a first mounting groove 1111 is formed on the male socket rubber core 111. The first contact portions 121 of the two rows of male socket terminals 12 are respectively installed on the inner walls on both sides of the first mounting groove 1111.

[0054] Furthermore, the female socket shell 21 includes an inner female socket rubber core 211 and an outer female socket rubber core 212 which is sleeved on the outside of the inner female socket rubber core 211. The inner female socket rubber core 211 is formed with a second mounting groove 2111. A protrusion 2112 is formed at the bottom of the second mounting groove 2111. The second contact portions 222 of the two rows of female socket terminals 22 are respectively installed on the two side surfaces of the protrusion 2112.

[0055] In some embodiments, a snap-fit ​​structure is formed at one end of the second contact portion 222 away from the second floating portion 223, and a mounting position matching the snap-fit ​​structure is formed on the protrusion 2112. By snapping the snap-fit ​​structure to the mounting position, the second contact portion 222 can be more firmly mounted on the protrusion 2112, thereby making the connection between the second contact portion 222 and the first contact portion 121 more stable, thereby ensuring the stability of the transmission.

[0056] In some embodiments, an empty cavity is further formed on the male rubber core 111, and the empty cavity is located below the first mounting groove 1111, and the first floating portion 122 is installed in the empty cavity. During installation, the first contact portion 121 passes through the through hole at the bottom of the first mounting groove 1111 and enters the first mounting groove 1111, and is installed on the inner wall of the first mounting groove 1111, and the first floating portion 122 is installed in the empty cavity.

[0057] In some embodiments, a cavity is formed between the female base inner rubber core 211 and the female base outer rubber core 212, and the second floating portion 223 is installed in the cavity. During installation, the second contact portion 222 penetrates into the second installation groove 2111 through the through hole at the bottom of the second installation groove 2111 and is installed on the side of the protrusion 2112, and the second floating portion 223 is installed in the cavity between the female base inner rubber core 211 and the female base outer rubber core 212.

[0058] The first mounting groove 1111 matches the second mounting groove 2111, so that the first mounting groove 1111 can be inserted into the second mounting groove 2111. In the specific implementation process, the first mounting groove 1111 can be selected to be fully inserted into the second mounting groove 2111, or it can be selected to be incompletely inserted, so as to achieve different matching heights between the male seat structure 1 and the female seat structure 2. In this example, the insertion distance between the first mounting groove 1111 and the second mounting groove 2111 is allowed to be 0 to 0.6 mm. For example, the matching height when the male seat structure 1 and the female seat structure 2 are fully inserted is 13.0 mm, and the matching height when the male seat structure 1 and the female seat structure 2 are incompletely inserted can reach up to 13.6 mm. By adjusting the insertion distance, different matching heights can be achieved to meet different installation requirements, and it has strong versatility.

[0059] As a further optimization, a snap-in groove is formed on the outer wall of the first mounting groove 1111, and a snap-in column matching the snap-in groove is formed on the inner wall of the second mounting groove 2111. In some embodiments, the snap-in groove of the first mounting groove 1111 can also be set as a snap-in column, and the snap-in column of the second mounting groove 2111 can be set as a snap-in groove. In this example, zero-gap snapping can be achieved between the snap-in groove and the snap-in column, so that the first mounting groove 1111 and the second mounting groove 2111 can be tightly plugged in, ensuring that the first mounting groove 1111 and the second mounting groove 2111 are not easy to loosen or fall off even under environmental conditions such as high-frequency vibration, ensuring the stability of the connection between the male terminal 12 and the female terminal 22, and achieving high-stability transmission.

[0060] As a further optimization, both ends of the male seat rubber core 111 and the female seat outer rubber core 212 are provided with slots 3, and a fixing sheet 31 is provided in the slot 3. The fixing sheet 31 is used to connect with the circuit board, so that the male seat structure 1 and the female seat structure 2 can be fixedly installed on the corresponding circuit board respectively to realize the transmission of current or signal.
