[0035] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0036] Embodiment 1

[0037] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 shown, a high-density elastic contact high-speed connector assembly is fixed on a PCB board 50 and used in cooperation therewith. The connector assembly includes a base 10, a plurality of ground contact members 30 and a plurality of signal contact members 40. The plurality of ground contact members 30 and the plurality of signal contact members 40 are both assembled inside the base 10 and are spaced apart.

[0038] The ground contact member 30 includes a contact member body A35. The head of the contact member body A35 has a docking structure A33, and the tail has an elastic structure A34. The signal contact member 40 includes a contact member body B45. The head of the contact member body B45 has a docking structure B43, and the tail has an elastic structure B44.

[0039] The docking structure A33 at the head of the ground contact member 30 and the docking structure B43 at the head of the signal contact member 40 are hidden inside the base 10 for docking with the connector assembly. The elastic structure A34 at the tail of the ground contact member 30 and the elastic structure B44 at the tail of the signal contact member 40 both extend outside the base 10 for elastic contact and cooperation with the PAD on the PCB board 50.

[0040] In this technical solution, the plurality of ground contact members 30 and the plurality of signal contact members 40 are spaced apart and assembled inside the base 10 to form a complete high-density elastic contact high-speed connector assembly. The complete high-density elastic contact high-speed connector assembly is fixed on the PCB board 50. The elastic structure A34 at the tail of the ground contact member 30 and the elastic structure B44 at the tail of the signal contact member 40 both extend outside the base 10 for elastic contact and cooperation with the PAD on the PCB board 50, realizing the transmission function between signals.

[0041] In the technical solution of this high-density elastic contact high-speed connector assembly, the reliable contact function is realized by adopting the elastic contact mode between the grounding contact 30, the signal contact 40 and the PAD on the PCB board 50, ensuring the reliable signal transmission between the PCB board 50 and the connector; through the docking structure A33 at the head of the grounding contact 30 and the docking structure B43 at the head of the signal contact 40 hidden inside the base 10 and docking with the connector assembly, the reliable contact between the contact and the docking end is realized, thus realizing the reliable high-speed signal transmission between PCB boards and between the PCB board and the device.

[0042] The high-density elastic contact high-speed connector assembly in this technical solution is applied to the PCB board. Due to its high contact reliability, it is more suitable for application scenarios with very high contact performance requirements.

[0043] To further optimize the reliable contact between the grounding contact 30 and the docking end, as Figure 3 shown, the docking structure A33 is a spring piece A arranged crosswise with the contact body A35; during the docking operation, the spring piece A arranged crosswise with the contact body A35 is deformed by force, and under the action of the reaction force of the spring piece A, the contact between the grounding contact 30 and the docking end is more stable.

[0044] To further optimize the reliable contact between the grounding contact 30 and the PCB board 50, as Figure 3 shown, the elastic structure A34 is composed of two juxtaposed elastic rod bodies I, and the elastic rod body I has a curvature. When the relative position between the connector assembly and the PCB board 50 is fixed, the elastic rod body I contacts the PAD, the elastic rod body I is deformed by force, and the elastic rod body I makes elastic contact with the PAD.

[0045] The elastic rod body I is set to be two juxtaposed ones, so that it has a certain supporting ability and at the same time has sufficient elastic deformation ability to ensure the reliable contact between the grounding contact 30 and the PCB board 50.

[0046] In this embodiment, the elastic rod body I is in a wavy shape as a whole, and the deformation of the elastic rod body I is manifested as elastic compression. In other embodiments, the elastic rod body I can be set to other shapes that meet the curvature requirements, such as a V shape.

[0047] To further optimize the reliable contact between the signal contact 40 and the docking end, as Figure 4 shown, the docking structure B43 is a spring piece B arranged crosswise with the contact body B45; during the docking operation, the spring piece B arranged crosswise with the contact body B45 is deformed by force, and under the action of the reaction force of the spring piece B, the contact between the signal contact 40 and the docking end is more stable.

[0048] To further optimize the reliable contact between the signal contact 40 and the PCB board 50, as Figure 4 shown, the elastic structure B44 is set as the second elastic rod body. The second elastic rod body has a curvature. When the relative position between the connector assembly and the PCB board 50 is fixed, the second elastic rod body contacts the PAD. The second elastic rod body deforms under force, and the second elastic rod body makes elastic contact with the PAD.

[0049] In this embodiment, the whole of the second elastic rod body is wavy, and the deformation of the second elastic rod body is manifested as elastic compression. In other embodiments, the second elastic rod body can be set to other shapes that meet the curvature requirement, such as a V shape.

[0050] To increase the contact area, improve the contact stability, and at the same time endow it with a certain supporting ability, a block 441 is provided on the second elastic rod body.

[0051] In this technical solution, the grounding contact 30 and the signal contact 40 are structurally optimized, further improving the transmission rate of the product, and being applicable to the reliable transmission of high-speed signals of the connector.

[0052] To meet the setting requirement of fixing the density elastic contact high-speed connector assembly to the PCB board 50 and cooperating with it in this technical solution, as Figure 1 、 Figure 5 shown, an installation seat 13 is provided on the outside of the base 10. A rivet 20 passes through the installation seat 13 and is riveted after passing through the PCB board 50.

[0053] The rivet 20 passes through the installation seat 13, passes through the PCB board 50, and then is riveted to realize the fixing function between the connector assembly and the PCB board 50.

[0054] To realize the setting method of assembling the grounding contact 30 inside the base 10, as Figure 2 、 Figure 3 shown, a first square groove 11 for accommodating the grounding contact 30 is provided inside the base 10, and a first stepped structure 111 is provided in the first square groove 11;

[0055] A convex structure A31 is provided on the contact body A35. When the grounding contact 30 is assembled into the first square groove 11, the convex structure A31 abuts against the first stepped structure 111, preventing the grounding contact 30 from moving towards the docking end inside the first square groove 11, playing a role of limiting and fixing.

[0056] After the relative position between the connector assembly and the PCB board 50 is fixed, the first stepped structure 111 cooperates with the PCB board 50 to limit the grounding contact 30 inside the first square groove 11, realizing the stable assembly of the grounding contact 30 inside the first square groove 11.

[0057] AsFigure 2 , Figure 3 As shown in Figure 3 , a barb structure A32 is provided on the contact body A35, and the barb structure A32 cooperates with the first square groove 11; the function of preventing the contact body A35 from moving up and down in the base 10 is realized, ensuring that the position of the contact body A35 is fixed when the connector is docked.

[0058] The provision of the boss structure A31 and the barb structure A32 on the ground contact 30 improves the stability of the ground contact 30 assembled inside the base 10, and further optimizes the design requirements for reliable contact.

[0059] To implement the setting method of the signal contact 40 assembled inside the base 10, as Figure 2 , Figure 4 shown, a second square groove 12 for accommodating the signal contact 40 is opened inside the base 10, and a second step structure 121 is provided inside the second square groove 12;

[0060] A boss structure B41 is provided on the contact body B45. When the signal contact 40 is assembled into the second square groove 12, the boss structure B41 abuts against the second step structure 121, preventing the signal contact 40 from moving in the direction of the docking end inside the second square groove 12, playing a role of limiting and fixing.

[0061] After the relative position of the connector assembly and the PCB board 50 is fixed, the boss structure B41 cooperates with the PCB board 50 to limit the signal contact 40 inside the second square groove 12, realizing the stable assembly of the signal contact 40 inside the second square groove 12.

[0062] As Figure 2 , Figure 4 shown, a barb structure B42 is provided on the contact body B45, and the barb structure B42 cooperates with the second square groove 12; the function of preventing the contact body B45 from moving up and down in the base 10 is realized, ensuring that the position of the contact body B45 is fixed when the connector is docked.

[0063] The provision of the boss structure B41 and the barb structure B42 on the signal contact 40 improves the stability of the signal contact 40 assembled inside the base 10, and further optimizes the design requirements for reliable contact. The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
