The embodiment of the disclosure provides a signal connector between printed circuit boards, which solves the problems that the existing signal connector between printed circuit boards is unreasonable in design, poor in heat dissipation effect and incapable of meeting user requirements by enabling a shielding component in the signal connector to have a heat dissipation effect, and achieves the purpose of improving the heat dissipation effect of the signal connector between printed circuit boards.
Fig. 1 is a schematic partial structure diagram of a signal connector between printed circuit boards according to an embodiment of the present invention. Fig. 2 is a perspective view of the signal connector between the printed circuit boards in fig. 1 mounted between two printed circuit boards facing each other. FIG. 3 is a schematic sectional view taken along line A1-A2 in FIG. 2. Fig. 4 is a schematic top view of the signal connector between the printed circuit boards of fig. 1. Referring to fig. 1 to 4, the signal connector 30 between the printed wiring boards is adapted to be mounted between the first printed wiring board 10 and the second printed wiring board 20 which are opposed to each other; at least one first connecting pin 11 is arranged on one side of the first printed circuit board 10 close to the second printed circuit board 20; the second printed wiring board 20 is provided with at least one second connection pin 21 on a side thereof adjacent to the first printed wiring board 10.
The signal connector 30 includes a first shielding wall 311, a second shielding wall 312 and at least one conductive connecting member 32; the first shielding wall 311 is opposite to the second shielding wall 312; the first shielding wall 311, the second shielding wall 312, the first printed circuit board 10 and the second printed circuit board 20 together enclose a closed annular hollow area; a plurality of partition walls 35 are arranged in the annular hollow area, and the partition walls divide the annular hollow area into a plurality of closed sub-areas; the first shielding wall 311, the second shielding wall 312 and the partition wall 35 are made of metal materials; the first shield wall 311 and the second shield wall 312 are each multiplexed as a support member so that the interval between the first printed wiring board 10 and the second printed wiring board 20 is kept constant; a conductive connection 32 is provided in at least some of the sub-regions; the conductive connecting member 32 includes a first end and a second end opposite to each other, the first end is electrically connected to the first connecting pin 11, and the second end is electrically connected to the second connecting pin 21; the conductive connection member 32 is electrically insulated from the first shielding wall 311, the second shielding wall 312, and the partition wall 35.
The first shielding wall 311, the second shielding wall 312 and the partition wall 35 are used to effectively suppress various electromagnetic interferences propagating through the space, and simultaneously, the radiation of the electrical signal transmitted by the conductive connecting member 32 can be reduced, and the probability of the electrical signal leakage can be reduced.
Those skilled in the art will appreciate that in practice, the side of the first printed wiring board 10 adjacent to the second printed wiring board 20 will often be provided with a plurality of components; similarly, the side of the second printed wiring board 20 adjacent to the first printed wiring board 10 is often provided with a plurality of components. Assuming that the height of the component disposed on the side of the first printed circuit board 10 close to the second printed circuit board 20 in the Y-axis direction is H1, and the height of the component disposed on the side of the second printed circuit board 20 close to the first printed circuit board 10 in the Y-axis direction is H2, the distance H between the first printed circuit board 10 and the second printed circuit board 20 needs to be equal to or greater than H1+ H2, so that each component on the printed circuit board is not damaged by being squeezed. In the above technical solution, the purpose of multiplexing the first shielding wall 311 and the second shielding wall 312 as the supporting component is to make the distance H between the first printed circuit board 10 and the second printed circuit board 20 equal to or greater than H1+ H2 and keep the distance H unchanged.
In order to reuse the first shielding wall 311 and the second shielding wall 312 as the supporting component, the first shielding wall 311 and the second shielding wall 312 have a certain thickness in the X direction in fig. 3, so that the first shielding wall 311 and the second shielding wall 312 have a certain carrying capacity in the Y direction in the figure, and thus the distance between the first printed circuit board 10 and the second printed circuit board 20 can be kept unchanged. Therefore, when the first shielding wall 311 and the second shielding wall 312 are reused as the support member, the first shielding wall 311 and the second shielding wall 312 need to be made large in volume.
On the basis, the material of the first shielding wall 311, the second shielding wall 312 and the partition wall 35 is a metal material, such as copper. Since the metal material has a better heat conduction capability, and the overall size of the first shielding wall 311, the second shielding wall 312 and the partition wall 35 is larger, which is beneficial to heat dissipation, the first shielding wall 311 and the second shielding wall 312 have a better heat dissipation effect. In the using process, the heat generated by the conductive connecting piece 32 due to signal transmission can be led out through the first shielding wall 311 and the second shielding wall 312, the possibility of heat accumulation around the conductive connecting piece 32 is reduced, the problems that the existing signal connector between printed circuit boards is unreasonable in design, poor in heat dissipation effect and incapable of meeting user requirements are solved, and the purpose of improving the heat dissipation effect of the signal connector between the printed circuit boards is achieved.
Alternatively, the first shielding wall 311, the second shielding wall 312 and the partition wall 35 may be grounded to the first printed circuit board 10 at a single point, or may be grounded to multiple points, which is not limited in this application. Compared with single-point grounding, the area of the part, electrically connected with the grounding pin, of the first shielding wall 311, the second shielding wall 312 and the partition wall 35 in multipoint grounding is larger, so that the impedance of a grounding loop can be reduced, the risk of leakage of an electric signal transmitted by the conductive connecting part 32 in any direction is reduced, and the multipoint grounding structure is suitable for high-frequency electric signal transmission.
If multi-point grounding is adopted, optionally, referring to fig. 3, the first printed circuit board 10 is provided with the first grounding pin 12, and when the signal connector 30 is installed between the first printed circuit board 10 and the second printed circuit board 20, the vertical projections of the first shielding wall 311, the second shielding wall 312 and the partition wall on the first printed circuit board 10 are all located within the vertical projection of the first grounding pin 12 on the first printed circuit board; and the first shielding wall 311, the second shielding wall 312 and the partition wall are electrically connected to the first ground pin 12 at various positions of the surface of the first printed wiring board 10.
Optionally, with continued reference to fig. 3 and 4, the signal connector 30 further comprises an insulating sleeve 33, the insulating sleeve 33 being located in the sub-region where the conductive connection 32 is located and surrounding the conductive connection 32. On the one hand, the insulating sleeve 33 can fix the position of the conductive connecting piece 32, ensure that the conductive connecting piece 32 is always electrically insulated from the first shielding wall 311, the second shielding wall 312 and the partition wall 35, and avoid the bad condition of electric conduction caused by the shaking of the mainboard comprising the signal connector; on the other hand, the insulating sleeve 33 may further serve as a support so that the distance between the first printed wiring board 10 and the second printed wiring board 20 is kept constant to improve the stability of the main board including the signal connector.
Alternatively, in practice, the conductive connecting member 32, the first shielding wall 311, the second shielding wall 312 and the partition wall 35 may be fabricated first, and then the formed sub-regions may be filled with an insulating material. Alternatively, the insulating material is a liquid insulating material, and after the liquid insulating material is filled between the conductive connecting member 32 and the conductive metal layer 34, the liquid insulating material is cured to form the insulating sleeve 33.
It should be noted that, in fig. 4, only a part of the sub-regions is provided with one conductive connecting member 32, which is only a specific example of the present application and is not a limitation of the present application. Fig. 5 is a schematic top view of another signal connector between printed circuit boards according to an embodiment of the present invention. Illustratively, in fig. 5, one conductive connection 32 is provided in all sub-regions.
In addition, in fig. 4, the first shielding wall 311 and the second shielding wall 312 both enclose a rectangle, the second shielding wall 312 is located inside the first shielding wall 311, and the first shielding wall 311 and the second shielding wall 312 together form a zigzag structure, which is only a specific example of the present application and is not limited to the present application. In actual installation, the pattern enclosed by the first shielding wall 311 and the pattern enclosed by the second shielding wall 312 may be the same or different. And the pattern enclosed by the first shielding wall 311 and the pattern enclosed by the second shielding wall 312 may be other polygons, circles, ellipses, and the like. Fig. 6 is a schematic top view of another signal connector between printed circuit boards according to an embodiment of the present invention. Illustratively, in fig. 6, the first printed wiring board 10 and the second printed wiring board 20 collectively enclose a herringbone structure.
On the basis of the above technical solutions, optionally, at least one of the first end and the second end of the conductive connecting member 32 is electrically connected to the corresponding connecting pin in a direct contact manner; the first printed wiring board 10 and the second printed wiring board 20 are fixed as one body by a detachable structure. Wherein the detachable structure comprises at least one of a screw and a snap.
In the conventional soldering method, the solder used, i.e., tin, has poor conductivity, and the soldering method increases the impedance between the conductive connecting member 32 and the corresponding connecting pin. In addition, the electrical connection yield of the soldering manner is low due to process limitations. According to the technical scheme, the conductive connecting piece 32 is electrically connected with the corresponding connecting pin in a direct contact mode, the traditional mode that the conductive connecting piece 32 is electrically connected with the corresponding connecting pin by soldering tin welding is replaced, the impedance between the conductive connecting piece 32 and the corresponding connecting pin can be reduced, and the electric connection yield of the printed circuit board and the conductive connecting piece 32 can be improved. The method is particularly suitable for the transmission of signals with the voltage of 3.5GHz and above. In addition, the conductive connecting piece 32 is only in direct contact with the corresponding connecting pin, and is not welded, so that the printed circuit board can be reused, and the later maintenance procedure and cost of the printed circuit board can be reduced.
Fig. 7 is a schematic cross-sectional view of another signal connector between printed circuit boards according to an embodiment of the present invention when the signal connector is mounted on the first printed circuit board but not mounted on the second printed circuit board. In fig. 7, the second end of the conductive connection member 32 is electrically connected to the corresponding connection pin by direct contact, for example. The first end of the conductive connecting member 32 is electrically connected to the corresponding connecting pin by soldering.
On the basis of the above technical solutions, in order to enable the conductive connecting member to effectively perform electrical signal transmission between the first printed circuit board and the second printed circuit board, optionally, a direction perpendicular to a plane of the first printed circuit board is taken as a first direction; the conductive connecting piece can stretch in a first direction; the conductive connector is in a compressed state in a first direction when the signal connector is mounted between the first printed wiring board and the second printed wiring board.
Illustratively, with continued reference to fig. 7, when the signal connector is mounted on the first printed wiring board 10 but not on the second printed wiring board, the height of the conductive connecting member 32 in the first direction (i.e., Y direction in fig. 7) is higher than the height of the first shielding wall 311 (or the second shielding wall 312). Fig. 8 is a schematic sectional view showing a structure after a second printed circuit board is mounted on the base of fig. 7. Comparing fig. 7 and 8, when the second printed wiring board is mounted, the conductive connection member 32 is at the same height as the first shielding wall 311 (or the second shielding wall 312) in the first direction (i.e., the Y direction in fig. 8). Since the first printed wiring board 10 and the second printed wiring board 20 are fixed as a single body, when the signal connector is mounted between the first printed wiring board 10 and the second printed wiring board 20, the conductive connecting member 32 is compressed in the first direction (i.e., Y direction in fig. 8), and the conductive connecting member 32 applies a pressure to the second printed wiring board 20, which is directed from the conductive connecting member 32 to the second printed wiring board 20. This pressure causes the second end of the conductive connector 32 to press against the corresponding connection pin on the second printed circuit board 20, which may improve the stability of the electrical connection there.
Optionally, the conductive connection 32 is a metal spring.
The first end of the conductive connecting piece is electrically connected with the first connecting pin in a welding mode, and the second end of the conductive connecting piece is electrically connected with the corresponding connecting pin in a direct contact mode. Like this, when the installation, can be earlier with the first end of electrically conductive connecting piece through welded mode and first connection pin electricity be connected, the rigidity of electrically conductive connecting piece and first printed circuit board this moment, the follow-up second end and the connection pin electricity that corresponds of electrically conductive connecting piece of mode through direct contact of being convenient for are connected, can reduce the degree of difficulty of installation.
