[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Reference Figures 1-7 The present invention provides an embodiment of a multi-dimensional system integration interconnection component, wherein the interconnection component is disposed between printed circuit boards, and the interconnection component includes: a protection unit 1; a receiving cavity is formed inside the protection unit 1, and a connecting unit 2 is disposed inside the receiving cavity; the connecting unit 2 extends in multiple end face directions of the protection unit 1 and passes through to the outside of the protection unit 1, and the printed circuit boards located at different end faces of the interconnection component are connected through the connecting unit 2.

[0038] In this embodiment, parallel printed circuit boards and vertical printed circuit boards, as well as parallel printed circuit boards and parallel printed circuit boards, are connected by interconnect components to achieve three-sided interconnection. A connecting unit 2 is provided inside the protection unit 1. The connecting unit 2 is installed, guided, and protected. The connecting unit 2 extends from multiple end faces of the protection unit 1 to connect with external printed circuit boards, realizing three-dimensional interconnection. This improves the assembly density of subsequent products, reduces product size, shortens the length of interconnect line transmission, reduces signal noise, and solves the problem that in high-performance systems, excessively long interconnect lines not only affect signal transmission quality but can even cause logic errors.

[0039] The protection unit 1 includes a first housing 11, a second housing 12 and a third housing 13. The first housing 11 and the second housing 12 are arranged opposite to each other, and the third housing 13 is arranged above the first housing 11 and the second housing 12, and are spliced ​​together to form a receiving cavity.

[0040] In this embodiment, the first housing 11 and the second housing 12 are arranged opposite to each other and connected by screws to form an inwardly recessed rectangular groove structure. The third housing 13 is disposed on the first housing 11 and the second housing 12 and connected by screws to form a receiving cavity for placing the connecting unit 2 and protecting the connecting unit 2 on the inner side.

[0041] The first housing 11, the second housing 12 and the third housing 13 have slots on their end faces, allowing the connecting unit 2 to extend to the outside, and the third housing 13 limits the connection unit.

[0042] In this embodiment, the connecting unit 2 extends to the outside through the slot for electrical connection with the external printed circuit board. The first housing 11, the second housing 12 and the third housing 13 can limit the surrounding area of ​​the connecting unit 2 to prevent the connecting unit 2 from rotating or deforming during interconnection, thus affecting the connection effect.

[0043] The connecting unit 2 includes a first insulating member 21 and a second insulating member 22. There are two first insulating members 21, and the second insulating member 22 is vertically disposed between the two first insulating members 21.

[0044] In this embodiment, two first insulating members 21 are provided and are arranged opposite to each other, located at the first housing 11 and the second housing 12 respectively. The second insulating member 22 is perpendicular to the first insulating member 21 and is located between the two first insulating members 21 to prevent the first insulating member 21 from being displaced.

[0045] One side of each of the two first insulating members 21 is coplanar with the end faces of the first housing 11 and the second housing 12 respectively through the slot, and one side of the second insulating member 22 is coplanar with the end face of the third housing 13.

[0046] In this embodiment, one side of the two first insulating members 21 is coplanar with the end face of the first housing 11 and the second housing 12, and one side of the second insulating member 22 is coplanar with the end face of the third housing 13. When interconnecting, the end face is attached to the external printed circuit board to ensure that the connection unit 2 can be effectively connected and to avoid the problem of poor connection contact.

[0047] The first insulating member 21 or the second insulating member 22 is provided with a plurality of through holes, so that the first insulating member 21 and the second insulating member 22 are connected.

[0048] In this embodiment, the first insulating member 21 is provided with 12 through holes in a single row, and the second insulating member 22 is provided with 12 through holes in two rows. The through holes on the first insulating member 21 are connected to the row of through holes on the second insulating member 22 that are close to each other, so as to achieve interconnection.

[0049] An elastomer 23 and a conductor 24 connected to one side of the elastomer 23 are provided inside the through hole. One side of the conductor 24 extends to the outside of the first insulator 21 or the second insulator 22 for elastic interconnection.

[0050] In this embodiment, the elastic body 23 is a button connector with conductive and stretchable characteristics. It is vibration resistant, resistant to insertion and removal, and has better high-frequency performance than ordinary spring pins. It replaces rigid pins and reduces insertion and removal wear. The elastic body 23 is clearance-fitted with the through hole. The conductor 24 is connected to one side of the elastic body 23, and part of the conductor 24 extends to the outside of the first insulating member 21 or the second insulating member 22. When performing plug-in interconnection, the conductor 24 is springed back by the elastic body 23, and the springback margin is 0.3mm.

[0051] The other side of the elastic body 23 extends into the second insulating member 22. The second insulating member 22 has a cavity, and a connector 25 is provided inside the cavity. The connector 25 is connected to the elastic body 23.

[0052] In this embodiment, the other side of the elastic body 23 extends into the inner cavity of the second insulating member 22 and is connected to the connector 25. The inner cavity of the second insulating member 22 is divided into multiple cavity areas to place the connector 25. The position of the connector 25 corresponds to the position of the through hole and is used to electrically connect with the elastic body 23 to realize electrical signal transmission.

[0053] The second insulating member 22 is provided with a pressure block 26, which is used to limit the connection body 25.

[0054] In this embodiment, a pressure block 26 is provided on the second insulating member 22. The pressure block 26 is used to install on one side of the cavity to limit the connector 25 inside the cavity, so as to prevent the connector 25 from moving during the plug-in interconnection, which would result in poor contact with the elastic body 23 and affect the connection effect.

[0055] The first housing 11 and the second housing 12 are provided with pins 3, and the end face of the third housing 13 is provided with a positioning pin 4.

[0056] In this embodiment, the pin 3 and the positioning pin 4 are provided to facilitate rapid positioning during plug-in interconnection.
