[0036] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. [Specific implementation method]

[0037] Please refer to Figures 1 to 6 As shown, a mating assembly 100 in accordance with the first embodiment of the present invention comprises a conductive terminal 10 and a mating terminal 20 mating with the conductive terminal 10. The conductive terminal 10 is an elastic terminal, and the mating terminal 20 is a flat structure as a whole.

[0038] The conductive terminal 10 includes a base 11 and a mating end 13 located in front of the base 11 and mating with the mating terminal 20. The mating end 13 includes a first mating portion 130 mating with the mating terminal 20 and a second mating portion 140 disposed in front of the first mating portion 130 and mating with the mating terminal 20. The first mating portion 130 includes a first protrusion 131, and the second mating portion 140 includes a second protrusion 141. The first protrusion 131 and the second protrusion 141 protrude toward the same side of the terminal. The first protrusion 131 is a non-elastic protrusion structure formed by stamping, and the first protrusion 131 includes a pair of stamping surfaces 133 formed by stamping. The second protrusion 141 is an elastic protrusion structure bent from the second mating portion 140.

[0039] The mating terminal 20 includes a straight mating contact portion 21, and the mating contact portion 21 includes a first surface 201 facing the conductive terminal. The mating contact portion 21 includes a first mating contact portion 230 and a second mating contact portion 240 connected to the first mating contact portion 230. The first mating contact portion 230 includes a groove 231 along the front-to-back direction, and the groove 231 includes two opposite side walls 233. The groove 231 passes through the front end of the mating terminal 20 forward so as to receive the first protrusion 131 in the groove 231 from the front end.

[0040] After the conductive terminal 10 is matched with the docking terminal 20, the second protrusion 141 is in contact with the second mating contact portion 240, and the first protrusion 131 is in contact with the first mating contact portion 230. The first protrusion 131 and the second protrusion 141 are in contact with the mating contact portion 21 of the docking terminal 20 in different ways. Specifically, in this embodiment, the first protrusion 131 is non-elasticly matched with the docking terminal 20, and the second protrusion 141 is elastically pressed against the first surface 201 of the docking terminal 20. In addition, the first protrusion 131 and the second protrusion 141 are in different matching directions with the docking terminal 20. Specifically, in this embodiment, the second protrusion 141 is in contact with the first surface 201 of the docking terminal 20 along a first direction. The first direction is the direction in which the first protrusion 131 and the second protrusion 141 are raised relative to other positions of the mating end 13. The first protrusion 131 is in contact with the docking terminal 20 along a second direction perpendicular to the first direction and perpendicular to the front-back direction. In this embodiment, the dimension of the first protrusion 131 along the second direction is greater than the dimension of the slot 231 in the second direction, so that the two opposite stamping surfaces 133 of the slot 231 can clamp the side wall 233 to form an effective contact fit.

[0041] In this embodiment, the conductive terminals 10 and the docking terminals 20 in the mating component 100 are mostly designed in pairs, and are used for the structural design of differential signal terminal interconnection. This structural design can be used for related connector products with high-speed signal transmission specifications such as backplane connectors. Of course, it can also be adapted to the structural design of other non-differential pair terminal interconnections.

[0042] Please refer to Figures 5 to 8 As shown in the figure, the second embodiment of the mating assembly 100' of the present invention is in accordance with the first embodiment. Compared with the first embodiment, the second mating portion 140' of the conductive terminal 10' of the present invention includes a narrow groove 40 extending in the front-to-back direction, and the narrow groove 40 divides the second mating portion 140' into a pair of elastic mating arms each having a second protrusion 141'. The provision of the narrow groove 40 reduces the flexural strength of the second mating portion 140', making it easier for the first mating portion 130' to contact and mate with the butt terminal 20.

[0043] The mating component of the present invention adds a contact point on the basis of the traditional structural design, which effectively solves the influence of the capacitance effect of single-point contact on impedance matching during high-speed signal transmission, improves the impedance matching after mating, and improves insertion loss. In addition, the mating direction and mating method of the first protrusion of the mating component of the present invention and the mating terminal are different from the mating direction and mating method of the second protrusion and the mating terminal, so as to ensure that the first mating part and the second mating part can achieve reliable contact and mating with the mating terminal, so that the conductive terminal of the mating component can reliably achieve multi-point contact and mating with the mating terminal.

[0044] The above is only one embodiment of the present invention, not all or the only embodiment. Any equivalent changes made to the technical solution of the present invention by ordinary technicians in this field after reading the specification of the present invention are covered by the claims of the present invention.
