With the rapid development of electronic technology, the requirements for connectors between circuit boards are also increasing, demanding high-speed signal transmission, high integration, and flexible installation adaptability.

[0003] However, traditional board-to-board connectors suffer from problems such as high signal loss, weak anti-interference ability, and low contact reliability during high-speed signal transmission. Utility Model Content

[0004] In view of this, this application provides a micro-rectangular high-speed inter-board connector to improve signal transmission quality and achieve a compact size of the connector, thereby meeting the requirements of efficient space layout of electronic devices.

[0005] This application provides a micro rectangular high-speed inter-board connector, including a male connector and a female connector:

[0006] The male connector includes a male housing, a male insulating body, and a male terminal assembly. The male insulating body is disposed within the male housing, and the male terminal assembly is disposed within the male insulating body. The female connector includes a female housing, a female insulating body, and a female terminal assembly. The female insulating body is disposed within the female housing, and the female terminal assembly is disposed within the female insulating body.

[0007] The male terminal assembly includes multiple male signal terminals, and the female terminal assembly includes multiple female signal terminals. Both the male and female signal terminals are arranged in a micro-rectangular pattern, and the male and female signal terminals are plugged into each other in a one-to-one correspondence.

[0008] Each of the male signal terminals includes a male contact portion, a male connection portion, and a male solder portion.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0030] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 10 This embodiment provides a micro-rectangular high-speed inter-board connector 1, including a male connector 10 and a female connector 20. The male connector 10 includes a male housing, a male insulating body 12, and a male terminal assembly 13. The male insulating body 12 is disposed within the male housing, and the male terminal assembly 13 is disposed within the male insulating body 12. The female connector 20 includes a female housing, a female insulating body 22, and a female terminal assembly 23. The female insulating body 22 is disposed within the female housing, and the female terminal assembly 23 is disposed within the female insulating body 22. The male terminal assembly 13 includes multiple male signal terminals 131, and the female terminal assembly 23 includes multiple female signal terminals 231. Both the male and female signal terminals 131 are arranged in a micro-rectangular pattern, and each male signal terminal 131 is inserted into the female signal terminal 231 in a one-to-one correspondence.

[0032] Optionally, both the male end insulating body 12 and the female end insulating body 22 are made of LCP (liquid crystal polymer) material. LCP material has excellent electrical properties, low dielectric constant and low loss factor, which can effectively reduce signal attenuation and distortion during high-speed signal transmission. At the same time, it has good high temperature resistance and dimensional stability, ensuring reliable operation of the connector in harsh environments.

[0033] Optionally, both the male signal terminal 131 and the female signal terminal 231 have a micro-rectangular structure to achieve a small-pitch, high-density layout. The pins are located on both sides of the insulating body, and the number of pins can be flexibly configured according to different needs to meet the requirements of multi-pin connections.

[0034] Optionally, the rectangular high-speed inter-board connector provided in this embodiment has four different mating heights, namely a first mating height, a second mating height, a third mating height, and a fourth mating height, so that the connector can be selected at four heights during mating, thereby meeting the installation space requirements between different PCB boards.

[0035] Optionally, the surfaces of the male terminal assembly 13 and the female terminal assembly 23 are treated with a special electroplating process to obtain ideal insertion and extraction forces and contact resistance. The mating surfaces of the male terminal assembly 13 and the female terminal assembly 23 are designed with specific contact structures to ensure a good electrical connection during mating, reduce contact resistance, and improve the stability of signal transmission.

[0036] Optionally, both the male signal terminal 131 and the female signal terminal 231 are made of phosphor bronze, thus possessing both high strength (tensile strength ≥ 600 MPa) and high elasticity (elastic modulus ≈ 115 GPa), enabling them to withstand high-frequency vibration stress during 10 Gbps high-speed signal transmission compared to traditional brass. Furthermore, phosphor bronze also exhibits high fatigue resistance and corrosion resistance.

[0037] Alternatively, the surfaces of the male signal terminal 131 and the female signal terminal 231 may be gold-plated or nickel-plated with gold. The nickel layer acts as a diffusion barrier, preventing the copper substrate from diffusing into the gold layer.

[0038] Optionally, the pin spacing between the male signal terminal 131 and the female signal terminal 231 is 1.27mm, and the number of pins in a single row is 20-200.

[0039] Optionally, both the male end housing and the female end housing are provided with a shielding layer, for example, by plating a gold layer or a nickel / gold layer on the surface of the male end housing and the female end housing, in order to shield external electromagnetic interference.

[0040] In summary, the micro-rectangular high-speed board-to-board connector 1 provided in this embodiment reduces the connector's size and improves its integration by arranging the signal terminals in a micro-rectangular pattern, thus meeting the layout requirements of miniaturized electronic devices. Furthermore, the shielding structure formed on the exterior of the housing effectively reduces electromagnetic interference and improves the quality and stability of signal transmission. In addition, the micro-rectangular high-speed board-to-board connector 1 achieves ideal insertion and extraction forces and contact resistance through a special contact design and electroplating process, ensuring the reliability and stability of the connection.

[0041] Please see Figure 1 , Figure 2 , Figure 3 and Figure 8 Both the male end housing and the female end housing are provided with positioning structures 30, the positioning structure 30 including a positioning groove 32 provided on the male end housing and a positioning protrusion 31 provided on the female end housing.

[0042] In this embodiment, by matching the geometric shapes of the positioning protrusion 31 and the positioning groove 32, the male connector 10 and the female connector 20 are precisely aligned in a predetermined direction during the insertion process, avoiding misalignment of the signal terminals due to angular deviation, thereby effectively reducing the terminal contact failure rate and improving contact reliability.

[0043] Please see Figure 5 and Figure 9Both the male end housing and the female end housing are provided with trapezoidal guide surfaces 33 on their peripheral ends. The trapezoidal guide surfaces 33 are located at the front end in the connector insertion and removal direction. Their bottom edge coincides with the end face of the housing, and their top edge is recessed inward toward the center of the housing to form a guide bevel. The angle between the guide bevel and the axis of the housing is 15°-45°.

[0044] In this embodiment, the guide bevel of the trapezoidal guide surface 33 forms a progressive guide structure, providing mechanical guiding force in the initial stage of insertion, allowing the male and female connectors 20 to quickly enter the insertion process without precise alignment. Compared to traditional right-angle end faces, the guide surface can correct the insertion angle, reduce terminal contact deviation, and avoid terminal misalignment damage caused by manual operation or mechanical vibration.
