Conventional connectors and PCB boards (printed circuit boards) have been connected mainly by soldering or crimping. In such a structure, connectors that require soldering require specialized soldering equipment, and connectors that require crimping require large equipment for the crimping operation, making assembly very inconvenient. Therefore, when elements are densely arranged on conventional PCB boards, it causes great inconvenience in processing and production. Summary of the Invention

[0016] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described below clearly and completely with reference to the drawings of the embodiments of the present disclosure. Of course, the described embodiments are only some of the embodiments of the present disclosure, and are not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without using inventive ability also belong to the protection scope of the present disclosure.

[0017] It should be noted that when an element is said to be "fixed" to another element, it may be directly connected to the other element, or there may be other elements in between. When an element is said to be "connected" to another element, it may be directly connected to the other element, or there may be other elements in between.

[0018] As shown in FIG. 1, some embodiments of the present disclosure provide a high-density elastic-contact high-speed transmission connector assembly. This high-density elastic-contact high-speed transmission connector assembly includes an upper base 1 and a lower base 2. Contacts 4 are provided inside the upper base 1 and the lower base 2, and the number and positions of the contacts 4 correspond to the PADs on the PCB board to be connected (the distribution of the PADs on the PCB board is shown in FIG. 5, for example). The heads of the contacts 4 are located inside the upper base 1 and connect to the connection ends to realize signal transmission. The tails of the contacts 4 extend to the outside of the lower base 2 and connect to the PADs on the PCB board to bring the connector and the PCB board into elastic contact to realize signal transmission.

[0019] The high-density elastic contact high-speed transmission connector assembly further includes pins 3. As shown in Fig. 4, the pins 3 are connected to openings of the PCB board through through holes opened in the upper base 1 and the lower base 2 and are crimped to fix the connector and the PCB board.

[0020] In the high-density elastic contact high-speed transmission connector assembly according to some embodiments of the present disclosure, the upper base 1 and the lower base 2 are connected to restrict the up-down and left-right movement of the contacts 4, and the pins 3 realize a fixed connection between the connector and the PCB board. When the connector is fixedly connected to the PCB board, the heads of the contacts 4 connect to the connection ends, and the tails of the contacts 4 connect to the PADs on the PCB board. This makes elastic contact between the connector and the PCB board to realize signal transmission.

[0021] 1, 2 and 3, a square groove structure for mounting the contact 4 may be provided inside the lower base 2. A protrusion 21 may be provided inside the square groove structure.

[0022] The head portion of the contact 4 is a tip 41, which connects to a connection end to realize signal transmission. The tail portion of the contact 4 is made of an arc-shaped structure (curved structure) 46, which connects to a PAD on the PCB board and realizes signal transmission by elastically contacting the connector and the PCB board. The contact 4 is provided with an assembly guide structure 42 for guiding assembly, a stopper structure 44 that engages with the protrusion 21 to ensure the fixing performance of the contact 4 within the upper base 1 and the lower base 2, and a cantilever structure 45 that contacts the PAD on the PCB board by elastic deformation to realize signal transmission between the connector and the PCB board.

[0023] The contact 4 is further provided with a barbed structure 43. Accordingly, the square groove structure is provided with a through hole structure 22. The engagement between the barbed structure 43 provided on the contact 4 and the through hole structure 22 provided on the square groove structure prevents the contact 4 from moving up and down within the upper base 1 and the lower base 2, and ensures that the contact 4 does not move when the connectors are connected.

[0024] The high density elastic contact high speed transmission connector assembly according to the embodiment of the present disclosure realizes reliable contact by elastic contact in the design of the contacts 4 of the product. Specifically, the contacts 4 are fixed by the upper base 1 and the lower base 2, and the finished connector is assembled. The connector is fixed to the PCB board by the pins 3. Such contact by the contacts 4 can ensure the reliability of signal transmission between the PCB board and the connector, and the reliability of contact between the contacts 4 and the connection ends, thereby realizing reliable signal transmission between PCB boards and between the PCB board and the device.
