Description

TECHNICAL FIELD

[0001] The present application relates to the field of adapters, in particular to a planar interconnection connector and integrated assembly. BACKGROUND

[0002] The integrated interconnection adapter is used to solve the problems of vibration, non-uniform thermal expansion and small inter-plate spacing. It has reliability characteristics such as mechanical stress resistance, solder-free maintenance and long-term stability, and meets the needs of small spacing, planar elastic connection and high density integration. The existing integrated interconnection adapter uses elastic connection to eliminate the plate tolerance. Due to the poor isolation between channels caused by planar interconnection, signal reflection and self-excitation are easily caused. If the existing SMP connector elastic integrated connection method is used, the problem of poor isolation between channels can be solved, but the plate height is generally not less than 17.5mm. The large interconnection height brings difficulties to integration. At the same time, due to factors such as multi-layer printed board thickness processing error, the problem of large interconnection height error between plates is caused. SUMMARY

[0038] 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.

[0039] Existing SMP connectors with flexible integration can solve the problem of poor isolation between channels, but the inter-board height is generally not less than 17.5mm. The large interconnect height brings difficulties to integration. At the same time, due to factors such as the thickness processing error of multilayer printed circuit boards, there is a large error in the inter-board interconnect height. To solve the above problems, it is necessary to design a planar interconnect structure with low inter-board interconnect, planar flexible connection, large axial tolerance, and high isolation.

[0040] The applicant designed several solutions in the research. Solution 1: To achieve a 50-ohm impedance match between the socket mating size and the pin outer diameter, the pin could use a button or spring pin structure. Using the button design, the button would need to be embedded inside the pin to achieve impedance matching within the adapter. From an assembly perspective, embedding the button into the pin is difficult. Furthermore, the pin design with barbs to secure it to the insulator to prevent the socket from falling out during adapter compression is flawed because the insulator thickness for pin fixation is insufficient. Therefore, this solution is not feasible.

[0041] Option 2: Considering the inability to assemble the raw button, a spring pin is used instead. One end of the spring pin needs to be fully compressed and in contact with the insert pin to achieve impedance matching. Simultaneously, barbs are required on both the insert pin and the spring pin for fixation. The barbs on the insert pin must overcome the spring force of the spring pin while also ensuring fixation during compression, placing excessive demands on the barb's design dimensions. In vibration and shock testing environments, the risk of using a spring pin is higher than that of a raw button, limiting its usability. If the barb design of the spring pin lacks sufficient fixation, it is highly likely that the spring pin will fall off during transportation.

[0042] To solve the aforementioned technical problems and avoid the problems arising from the two aforementioned solutions, the applicant has designed the implementation scheme of this application.

[0043] Reference Figures 1-4 An embodiment of the present invention provides a planar interconnect connector, comprising: a first plug-in component 1; the first plug-in component 1 is mounted on a first housing 2; a second housing 3 is disposed on the other side of the first housing 2, and a second plug-in component 4 is mounted on the other end of the second housing 3; an adapter component is disposed inside the first housing 2 and the second housing 3; an elastic member 5 is sleeved on the outer side of the second housing 3, and the elastic member 5 abuts against the first housing 2 and the second plug-in component 4; during plugging, the second housing 3 extends into the inner side of the first housing 2, and the adapter component is compressed by force, causing the first plug-in component 1 and the second plug-in component 4 to move towards each other along the same axial direction.

[0044] In this embodiment, during insertion, the first insertion component 1 and the second insertion component 4 move towards each other along the same axis, cooperating with the adapter component to ensure minimal coaxiality error throughout the signal transmission path. This design significantly reduces reflection, VSWR, and insertion loss in high-frequency signal transmission, ensuring signal integrity. The nested fit between the first housing 2 and the second housing 3 allows the second housing 3 to extend into the inner side of the first housing 2 during insertion, guided by the first housing 2 to ensure coaxial movement. The elastic element 5 on the outer side of the second housing 3 is compressed during insertion, absorbing the impact force during the insertion process and reducing component wear. After insertion, the elastic element 5 pushes the second insertion component to elastically reset. The elastic element 5 is a spring made of stainless steel with a passivated surface. During insertion, the second housing 3 retracts into the inner side of the first housing 2, while the adapter component is compressed. The two insertion structures form a floating compression distance, ensuring a 1mm compression stroke in the axial direction, achieving a large axial compression stroke while ensuring insertion isolation.

[0045] The first plug-in assembly 1 includes a first contact 101, and a second contact 102 is provided on one side of the first contact 101. One end of the second contact 102 is inserted into the inside of the first contact 101.

[0046] The outer diameter of one side of the first contact 101 matches the inner diameter of the first housing 2. The second contact 102 is located inside the first housing 2, with one side matching the inner diameter of the first contact 101 and the other side inserted into the inner side of the second housing 3.

[0047] In this embodiment, the outer diameter of the first contact 101 is adapted to the inner diameter of the first housing 2. One side of the second contact 102 is fitted with the inner diameter of the first contact 101, and the other side is inserted into the inner side of the second housing 3, which restricts the radial wobble of the first contact 101 and the second contact 102, ensuring the coaxiality of the first plug-in assembly 1 with the first housing 2 and the adapter assembly. The first contact 101 is directly connected to the first housing 2, and the second contact 102 is located on the inner side, responsible for the transition connection with the first contact and the second housing, dispersing the force to the housing, avoiding deformation or damage caused by the concentrated force on a single component. The first contact 101 and the second contact 102 form a double-layer shielding structure, which can effectively block external radio frequency interference. The structure of the second contact 102 inserted into the inner side of the second housing 3 plays a guiding role during the plugging process, guiding the second housing 3 into the first housing 2.

[0048] The first contact 101 and the second contact 102 form a cavity, and a first insulator 103 is disposed inside the cavity. The first contact 101 and the second contact 102 limit the end face of the first insulator 103, and the first insulator 103 extends to the outside along the inner diameter of the first contact 101.

[0049] In this embodiment, the cavity formed by the first contact 101 and the second contact 102 limits the two end faces of the first insulator 103, preventing the first insulator 103 from moving in the axial direction. The first insulator 103 isolates the first contact 101, the second contact 102, and the internal first pin 104, ensuring the electrical safety of signal transmission. The first insulator 103 can be removed and replaced by disassembling the second contact 102 without damaging the main structure of the contact, reducing maintenance costs. The first insulator 103 extends along the inner diameter of the first contact 101 to the outer side, forming a connection structure with the external insertion hole 12.

[0050] The inner side of the first insulator 103 is provided with a first pin 104 and a first button 105, which are connected to the adapter assembly through the first button 105.

[0051] In this embodiment, the first button 105 forms an elastic contact with the adapter assembly. The elastic deformation capability of the first button 105 can compensate for assembly tolerances. When the adapter is subjected to mechanical vibration, the button maintains continuous contact with the adapter assembly through elastic deformation, avoiding signal interruption due to loosening. This ensures that the first pin 104 and the first button 105 inside the first insulator 103 maintain a stable connection with the adapter assembly. The first insulator 103 provides precise radial and axial positioning for the first pin 104 and the first button 105, ensuring alignment accuracy with the adapter assembly.

[0052] The second plug-in assembly 4 includes a third contact 401, the inner diameter of one side of the third contact 401 being matched with the outer diameter of the second housing 3.

[0053] In this embodiment, the inner diameter of one side of the third contact 401 is adapted to the outer diameter of the second housing 3 to ensure the coaxiality of the second plug-in assembly 4 and the second housing 3, and reduce signal transmission loss. The third contact 401 and the second housing 3 are both made of metal, and after connection, they form a shielding layer to ensure isolation.

[0054] A cavity is formed between the second housing 3 and the third contact 401. A second insulator 402 is provided inside the cavity. The second housing 3 and the third contact 401 limit the end face of the second insulator 402, and one side of the second insulator 402 extends to the outside of the third contact 401.

[0055] In this embodiment, the cavity formed by the second housing 3 and the third contact 401 clamps and limits the two end faces of the second insulator 402, preventing axial movement of the second insulator 402. The second insulator 402 is made of high-frequency insulating material, such as polytetrafluoroethylene or alumina ceramic, to avoid the risk of short circuit or leakage. The portion of the second insulator 402 extending to the outside of the third contact 401 forms an external plug for inter-board connection.

[0056] The inner side of the second insulator 402 is provided with a fourth pin 403 and a second button 404, which cooperates with the adapter assembly.

[0057] In this embodiment, the fourth pin 403, as the core conductor for signal transmission, is made of a high-conductivity material, such as beryllium bronze, and is gold-plated on the surface to reduce contact resistance. The second button 404, as an elastic contact, abuts against the adapter assembly and can generate a compression of 0.3-0.5mm during the insertion process to compensate for pin manufacturing tolerances and assembly errors.

[0058] The adapter assembly includes a second pin 6 and a third pin 7, wherein the second pin 6 mates with the first insulator 103 and the third pin 7 mates with the second insulator 402;

[0059] The other end of the second pin 6 extends along the inner diameter of the second contact 102 to the inner side of the second housing 3. The third pin 7 has a socket 71 on the side near the second pin 6. One side of the second pin 6 extends into the socket 71 and cooperates with the third pin 7.

[0060] In this embodiment, one end of the second pin 6 is fitted with the inner diameter of the first insulator 103, extends into the inner side of the first insulator 103 and abuts against the first button 105 for electrical connection. One end of the third pin 7 is fitted with the inner diameter of the second insulator 402 and abuts against the second button 404 for electrical connection. The second pin 6 is connected to the insertion hole 71 of the third pin 7. When plugging in, the second pin 6 is inserted into the insertion hole 71 of the third pin 7 to achieve floating plugging.

[0061] The socket 71 adopts a gradually expanding inlet design and has an opening on the radial arc surface to facilitate the insertion of the second pin 6. The mating area between the second pin 6 and the third pin 7 is located inside the second housing 3, forming a closed space to protect the adapter assembly.

[0062] At least one slot is provided on the inner side of the first insulator 103 and the second insulator 402, and the slot cooperates with one end of the second pin 6 and the third pin 7 to limit their movement.

[0063] In this embodiment, the slot cross-section is triangular, forming a barbed structure. Corresponding protrusions are provided on the second pin 6 and the third pin 7. After assembly, the protrusions limit the end face of the slot, preventing the second pin 6 and the third pin 7 from falling out of the first insulator 103 and the second insulator 402. At the same time, coaxiality is ensured during assembly and insertion.

[0064] Reference Figure 5 It also includes an embodiment of an integrated component, wherein the interconnect component is adapted to any of the connectors described above, comprising:

[0065] The first integrated socket 8 is mounted on the first circuit board 9;

[0066] The second integrated socket 10 is mounted on the second circuit board 11;

[0067] The first integrated socket 8 and the second integrated socket 10 are provided with a plurality of plug holes 12;

[0068] The first integrated socket 8 and the second integrated socket 10 are arranged opposite to each other, so that the positions of the plug holes 12 correspond to each other;

[0069] The two ends of the connector are respectively inserted into the insertion holes 12 of the first integrated socket 8 and the second integrated socket 10, and electrically connected to the first circuit board 9 and the second circuit board 11 to ensure that the flatness of the first circuit board 9 and the second circuit board 11 is consistent.

[0070] In this embodiment, the insertion holes 12 of the first integrated socket 8 and the second integrated socket 10 are arranged in an array, forming at least one row of insertion holes 12 for integrated insertion. This ensures that both ends of the connector can be simultaneously inserted into the corresponding insertion holes 12. The connector generates axial compression during insertion, which can compensate for the flatness deviation between the first circuit board 9 and the second circuit board 11. The inner wall of the insertion hole 12 of the integrated socket is gold-plated and electrically connected to the first insertion component 1 or the second insertion component 4 of the connector.

[0071] The first integrated socket 8 and the second integrated socket 10 are connected to the first circuit board 9 and the second circuit board 11 via screws. Both ends of the connector are electrically connected to the first circuit board 9 and the second circuit board 11 via insertion holes 12, respectively. The spacing between the first circuit board 9 and the second circuit board 11 is 11-12mm. The connector ensures a 1mm compression stroke, forming a 50Ω impedance match at the circuit board end face. This structural design utilizes the connector's secondary compression of 1mm to solve the problem of spacing variations caused by errors and other factors between the 11-12mm boards. The first integrated socket 8 and the second integrated socket 10 are interconnected at both ends via screws, eliminating the need for soldering. This reduces the number of soldering steps on the circuit board and optimizes the soldering temperature gradient, making it more cost-effective than other types of connectors.
