The first board 01 may be specifically a PCB, and the second board 02 may be specifically an FPC, that is, the first seat 1 and the PCB may adopt SMT (Surface mount Technology), and the second seat 2 and the FPC may also adopt SMT for connection; of course, the first board 01 and the second board 02 may also be other types of circuit boards.

The first housing 1 has a cylindrical body 11, the second housing 2 has a docking hole 21, the cylindrical body 11 can be inserted into the docking hole 21, and the first housing 1 and the second housing 2 are coupled when the cylindrical body 11 is in contact with an inner wall of the docking hole 21.

In order to connect the first board 01 and the second board 02, the pillar 11 and the mating hole 21 are made of conductive material, such as copper, so that electrical signals can be transmitted between the first board 01, the second board 02, the first socket 1 and the second socket 2.

The cylindrical body 11 may be cylindrical, and the size of the docking hole 21 is matched with the cylindrical body 11, so that when the cylindrical body 11 extends into the docking hole 21, the outer sidewall of the cylindrical body 11 can contact with the inner wall of the docking hole 21, thereby realizing the transmission of the electrical signal.

Of course, the cylindrical body 11 can be provided with other shapes, and the size of the docking hole 21 is matched with the cylindrical body 11, and a specific embodiment of the docking hole 21 will be given later.

Referring to fig. 2 of the specification, the first seat 1 is provided with a disk-shaped body 12, the disk-shaped body 12 is located at a first end of the column-shaped body 11, the cross-sectional dimension of the disk-shaped body 12 may be larger than that of the column-shaped body 11, and the outer periphery of the disk-shaped body 12 has a first connection end 13.

The disk-shaped body 12 may be a flat cylinder, and the axis of the disk-shaped body 12 and the axis of the column-shaped body 11 may be arranged in a collinear manner, the first connection end 13 extends outward along the radial direction of the flat cylinder, and the plurality of first connection ends 13 may be uniformly distributed on the periphery of the disk-shaped body 12.

The first seat 1 may be integrally formed, that is, a conductive bar such as a copper bar is machined by a machining method to obtain the cylindrical body 11, the disc-shaped body 12 and the first connection end 13.

The first connecting end 13 can be regarded as a welding leg for welding and fixing with the first board 01; the disk-shaped body 12 can increase the contact area with the first plate 01 to ensure reliable connection of the first housing 1 and the first plate 01.

The second end of the columnar body 11 can be arranged to be tapered, that is, a conical structure without a sharp corner, as shown in fig. 2 in the description, the two ends of the columnar body 11 are respectively provided with the disc-shaped body 12 and the conical structure, and the second end of the columnar body 11 can be formed by turning and other processing methods, so that when the columnar body 11 needs to be inserted into the butt joint hole 21, the conical structure can play a role in guiding, thereby facilitating installation and improving assembly efficiency.

Referring to the description of fig. 3, the second seat 2 includes at least two elastic bodies 22, and two adjacent elastic bodies 22 are arranged at intervals, and the description of fig. 3 shows the case of four elastic bodies 22, all the elastic bodies 22 form the abutting holes 21, and all the elastic bodies 22 can be symmetrically distributed.

It can be seen that the wall of the docking hole 21 is not necessarily closed, but may be formed by a plurality of elastic bodies 22 arranged at intervals, each elastic body 22 has certain elasticity, and can move towards the outside for a certain distance after contacting the columnar body 11, that is, the docking hole 21 is wholly expanded outwards for a certain angle, similar to the opening process of the petals.

The elastomer 22 thus arranged, when the column 11 does not extend into the docking hole 21, the diameter of the docking hole 21 may be smaller than the diameter of the cross section of the column 11, and when the column 11 extends into the docking hole 21, the elastomer 22 is expanded after being pressed by the column 11, so that the column 11 and the inner wall of the docking hole 21 are tightly attached.

Of course, when the column 11 does not extend into the docking hole 21, the diameter of the docking hole 21 may be equal to the diameter of the cross section of the column 11, and the elastic body 22 will not be elastically deformed after the column 11 extends into the docking hole 21 without assembly error.

No matter how the diameter of the abutting hole 21 and the cross section diameter of the column body 11 are set, when assembly error occurs or the column body 11 falls off, acting force is applied to one or some elastic bodies 22 by the column body 11, the elastic bodies 22 with the acting force are elastically deformed, and at the moment, the column body 11 and the elastic bodies 22 with the elastic deformation can still keep contact, so that the first seat 1 and the second seat 2 are reliably connected.

By adopting the arrangement mode, the assembly error can be effectively compensated through the elastic deformation of the elastic body 22, and the connection reliability of the columnar body 11 and the butt joint hole 21 can still be ensured after the relative positions of the first seat 1 and the second seat 2 are changed.

The elastic body 22 is provided with a body part 221 in a necking shape, the inner wall of the body part 221 is contacted with the columnar body 11, and the body part 221 can be bent into an arc shape, namely, the opening sizes of two ends of the butt joint hole 21 are larger, and the middle size is smaller; the elastic body 22 may be formed by bending a material such as copper sheet.

In this way, the reduced position of the docking hole 21 clamps the cylindrical body 11 to ensure the stable connection between the first seat 1 and the second seat 2.

The second seat 2 is provided with an insulating coating member 23, and the insulating coating member 23 can be integrally formed by injection molding of a Polyamide (PA) material; the insulating coating 23 may be annular, and the insulating coating 23 is located at the end of the elastic body 22, as shown in fig. 3 in the specification.

The second seat 2 that so sets up can play better insulating effect through setting up insulating cladding piece 23 its week, can set up other sensitive components around insulating cladding piece 23 to avoid the emergence of creepage phenomenon, promoted the design flexibility.
