[0002] With the rapid development of computer high-speed interconnection and data communication, the parallel board-to-board interconnection application has increased from docking through a pair of board-to-board connectors to docking with multiple board-to-board connectors. As the number of board-to-board connectors increases, the positioning accuracy of board-to-board connector installation is also getting higher and higher.

[0003] The current board-to-board connectors have tolerances during processing and assembly. The accumulation of these tolerances will cause the signal terminals to deform in the X, Y, and Z directions during assembly, i.e., positional offset, making it difficult to dock multiple board-to-board connectors. Even if the board-to-board connectors are docked together, the signal terminals will not be in close contact, resulting in poor signal quality or even connector damage.

DETAILED DESCRIPTION

[0052] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0053] Example:

[0054] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 8 , Fig.11 , Fig.12 As shown, this embodiment discloses a floating board-to-board connector, including a male end component 10 and a female end component 20 adapted to each other, the male end component 10 includes a male end socket 100 and a plurality of pairs of male end signal terminals 101, the male end socket 100 is provided with a plurality of pairs of first plugging slots 102, the first plugging slots 102 are matched with the male end signal terminals 101, the male end signal terminals 101 include a first connecting arm 103 and a rigid contact arm 104 connected in sequence, the first connecting arm 103 and the rigid contact arm 104 can be plugged into the first plugging slot 102, and are respectively contacted with the inner side walls on both sides of the first plugging slot 102 for limiting position;

[0055] The female end assembly 20 includes a female end base 200, a female end socket 201 and a plurality of pairs of female end signal terminals 202. One end of the female end socket 201 is arranged in the female end base 200 and is gap-matched with the female end base 200. The female end base 200 is provided with a plurality of pairs of second plug-in slots 203. The female end socket 201 is provided with a plurality of pairs of third plug-in slots 204. The second plug-in slots 203 and the third plug-in slots 204 are matched with the female end signal terminals 202. The female end signal terminals 202 include a second connecting arm 205, a floating arm 206 and an elastic contact arm 207 connected in sequence. The second connecting arm 205 can be plugged into the second plug-in slot 203. The elastic contact arm 207 can be plugged into the third plug-in slot 204. The floating arm 206 is located between the female end base 200 and the female end socket 201.

[0056] The lower end of the male socket 100 can be plugged into the female socket 201, the first connecting arm 103 and the elastic contact arm 207 are located on the same axis, a V-shaped contact portion 208 is provided at one end of the elastic contact arm 207, and a yield groove 209 is provided at one end of the third plug-in slot 204 to cooperate with the V-shaped contact portion 208. When the male socket 100 is inserted into the female socket 201, the rigid contact arm 104 can interfere with the V-shaped contact portion 208 on the elastic contact arm 207.

[0057] The present invention sets the male end component 10 as a male end socket 100 and a plurality of paired male end signal terminals 101, sets the male end signal terminals 101 as a first connecting arm 103 and a rigid contact arm 104, then plugs the first connecting arm 103 and the rigid contact arm 104 into the first plugging slot 102 on the male end socket 100, and makes the first connecting arm 103 and the rigid contact arm 104 contact and limit with the inner side walls on both sides of the first plugging slot 102 respectively, so that the rigid contact arm 104 cannot be deformed, and then sets the female end component 20 as a female end base 200, a female end socket 201 and a plurality of paired female end signal terminals 202, sets one end of the female end socket 201 in the female end base 200, and matches with the female end base 200 with a clearance, sets the female end signal terminals 202 as a second connecting arm 205, a floating arm 206 and an elastic contact arm 207, and at the elastic contact arm 207 A V-shaped contact portion 208 is provided at one end, and then the second connecting arm 205 is inserted into the second plugging groove 203 on the female end base 200, and the elastic contact arm 207 is inserted into the third plugging groove 204 on the female end socket 201, so that the floating arm 206 is located between the female end base 200 and the female end socket 201, and at the same time, a yield groove 209 is provided at one end of the third plugging groove 204 on the female end socket 201, which is matched with the V-shaped contact portion 208, so that when the male end socket 100 and the female end socket 201 are plugged, the V-shaped contact portion 208 can be deformed toward one end of the yield groove 209 while contacting the rigid contact arm 104, and the floating arm 206 can absorb the deformation of the female end signal terminal 202 in the X, Y and Z directions, thereby solving the problem that the signal terminal is offset due to processing and assembly tolerances in the current board-to-board connector, and multiple board-to-board connectors are difficult to connect.

[0058] The female socket 201 and the female base 200 are connected via the female signal terminal 202, so that the female socket 201 itself and the female base 200 are floating. Therefore, in conjunction with the floating arm 206 in the female signal terminal 202, the deformation in the X, Y and Z directions can be absorbed.

[0059] Since the V-shaped contact portion 208 is provided on the elastic contact arm 207 in the female signal terminal 202, when the male socket 100 is plugged into the female socket 201, the rigid contact arm 104 in the male signal terminal 101 can always interfere with the V-shaped contact portion 208 on the elastic contact arm 207. The bottom of the V-shaped contact portion 208 is the contact point with the rigid contact arm 104, and the force generated by the deformation of the elastic contact arm 207 can ensure that the bottom of the V-shaped contact portion 208 always keeps in contact with the rigid contact arm 104, thereby ensuring stable and high-quality signal transmission.

[0060] The arrangement of the V-shaped contact portion 208 and the first connecting arm 103 and the elastic contact arm 207 being located on the same axis can effectively improve the impedance continuity of the mating interface, enhance the coupling of the entire path segment, and thus reduce the insertion loss.

[0061] like Fig.10 , Fig.12 As shown, in order to facilitate the improvement of the stability of the male socket 100 and the female socket 201 when plugged in, this embodiment is improved on the basis of the above embodiment, and the difference from the above embodiment is that the male socket 100 is provided with a first insertion portion 105 at the lower end, and the female socket 201 is provided with a first insertion groove 210 arranged in cooperation with the first insertion portion 105, the first insertion portion 105 can be plugged into the first insertion groove 210, the first insertion groove 210 is connected with a plurality of third insertion grooves 204, and the V-shaped contact portion 208 on the elastic contact arm 207 extends into the first insertion groove 210;

[0062] The female end socket 201 is provided with a second insertion portion 211, and the first insertion portion 105 is provided with a second insertion slot 106 adapted to the second insertion portion 211. The second insertion portion 211 can be inserted into the second insertion slot 106, and the second insertion slot 106 is connected to a plurality of first insertion slots 102, and one end of the rigid contact arm 104 extends into the second insertion slot 106;

[0063] When the male socket 100 is plugged into the female socket 201, the first insertion portion 105 is plugged into the first insertion groove 210, and the second insertion portion 211 is plugged into the second insertion groove 106. One end of the rigid contact arm 104 located in the second insertion groove 106 can interfere with one end of the V-shaped contact portion 208 on the elastic contact arm 207 located in the first insertion groove 210.

[0064] A first insertion portion 105 is provided at the lower end of the male socket 100, a first insertion groove 210 is provided on the female socket 201, a second insertion portion 211 is provided on the female socket 201, and a second insertion groove 106 is provided on the first insertion portion 105, so that the plugging of the male socket 100 and the female socket 201 can be more stable.

[0065] like Figure 4 As shown, in order to facilitate the male signal terminal 101 and the female signal terminal 202 to form a plug-in contact, this embodiment is improved on the basis of the above embodiment. The difference from the above embodiment is that a guide inclined surface 107 is provided at the end of the rigid contact arm 104 located in the second insertion groove 106, and the guide inclined surface 107 is matched with the end of the V-shaped contact portion 208 on the elastic contact arm 207.

[0066] The setting of the guiding slope can ensure that when the male socket 100 and the female socket 201 are plugged together, the male signal terminal 101 can contact the side of the V-shaped contact portion 208 of the female signal terminal 202, thereby forming a plug-in contact.

[0067] like Figure 3 , Fig.12 As shown, in order to facilitate the plugging between the male socket 100 and the female socket 201, this embodiment is improved on the basis of the above embodiment. The difference from the above embodiment lies in that the end of the first insertion portion 105 inserted into the first insertion groove 210 is provided with a first inclination angle 108, and the female socket 201 is provided with a second inclination angle 212 which is arranged to cooperate with the first inclination angle 108, and the second inclination angle 212 is arranged to cooperate with the first insertion groove 210.

[0068] The setting of the first inclination angle 108 and the second inclination angle 212 plays a guiding role when the male end socket 100 and the female end socket 201 are plugged into each other.

[0069] like Figure 6 As shown, in order to conveniently absorb the deformation in the X, Y and Z directions, this embodiment is improved on the basis of the above embodiment. The difference from the above embodiment is that the female signal terminal 202 and the male signal terminal 101 are both integrated structures and are formed by a bending and stamping process. The floating arm 206 in the female signal terminal 202 includes a first bending section 213, a first connecting section 214, a second bending section 215, a second connecting section 216 and a third bending section 217 connected in sequence. One end of the second connecting arm 205 is connected to the first bending section 213, and one end of the elastic contact arm 207 is connected to the third bending section 217. The first connecting section 214 is used to bear the twisting deformation in the X direction and the bending deformation in the Y direction. The second connecting section 216 is used to bear the bending deformation in the Z direction. The widths of the first bending section 213, the first connecting section 214, the second bending section 215, the second connecting section 216 and the third bending section 217 are greater than the widths of the second connecting arm 205 and the elastic contact arm 207.

[0070] The female signal terminal 202 and the male signal terminal 101 are both of an integrated structure and are formed by a bending and stamping process, which can effectively reduce the cost of assembly and production and maintain a high material utilization rate.

[0071] The first bending section 213 , the first connecting section 214 , the second bending section 215 , the second connecting section 216 and the third bending section 217 form a Z-shaped structure as a whole, so that the floating arm 206 can float in the X, Y and Z directions, and thus can absorb the deformation in the X, Y and Z directions.

[0072] The floating arm 206 increases in width and can effectively optimize the performance of signal transmission through smooth transition of the structures such as the first bending section 213 , the first connecting section 214 , the second bending section 215 , the second connecting section 216 and the third bending section 217 .

[0073] Among them, the bending angles on the inner sides of the first bending section 213 and the second bending section 215 are both less than 90°, the bending angle on the inner side of the third bending section 217 is equal to 90°, and the length of the second bending section 215 is longer than the lengths of the first bending section 213 and the third bending section 217, so that the bending angle of the second bending section 215 forms a smoother bending angle, thereby making the structure of the female signal terminal 202 smoother, thereby optimizing the signal transmission performance.

[0074] like Figure 6 , Fig.12 As shown, in order to facilitate the installation of the female signal terminal 202 and the male signal terminal 101, this embodiment is improved on the basis of the above embodiment.
