Description

Technical Field

[0001] This application belongs to the field of electrical connection accessories technology, specifically relating to a miniaturized connector that allows for quick insertion / disconnection, high-temperature environments, high current operation, and long-lasting durability. Background Technology

[0002] In existing technologies, connectors, as key components for signal and power transmission in electronic devices, play a crucial role in chip testing, aging tests, and other fields. Especially in scenarios involving frequent replacement of chip test substrates and fixed use within aging chambers, they provide a stable high-current test power supply to the testing equipment, enabling rapid connection between test modules and the substrate, ensuring the continuity and accuracy of the testing process, and thus improving chip testing efficiency and product quality control. However, connectors currently available on the market suitable for sealed, continuous high-temperature environments have some shortcomings and cannot meet the stringent requirements of repeated use.

[0003] In existing technologies, conventional high-temperature connectors are often designed to be large in size to ensure their electrical performance and structural stability in high-temperature environments. This results in a large installation space, making flexible placement difficult in chip testing scenarios with high equipment integration requirements, severely limiting the miniaturization of testing systems. Furthermore, these connectors mostly use cable screw fixing methods. While this method offers some stability, in actual operation, especially in scenarios requiring frequent replacement of chip test substrates, the disassembly and assembly process is extremely cumbersome. This not only consumes a lot of time and reduces testing efficiency, but also lacks a point of leverage during insertion and removal, making it difficult for operators to apply appropriate force to smoothly remove the plug. Forced operation may even damage the connector or test substrate, failing to meet the requirements of frequent chip test substrate replacement and fixed use in aging chambers. In addition, when used continuously in high-temperature environments for extended periods, the internal contacts of some connectors are prone to oxidation and wear, leading to decreased conductivity and difficulty in stably providing high current. Moreover, the durability of the mechanical locking structure is insufficient; after repeated insertion and removal cycles, the locking may become insecure, affecting the overall lifespan and reliability of the connector.

[0004] Therefore, in order to comprehensively improve the connector's spatial adaptability, ease of operation, current transmission stability, and mechanical durability in high-temperature environments, and to meet the needs of chip testing and other scenarios for miniaturization, rapid connection, and long-term durability, it is now urgent to improve the existing connectors to enhance the testing efficiency and operational reliability of the equipment.

[0024] Combination Figures 1 to 7 The content shown further illustrates the technical solution proposed in this application. This application adopts the following technical solution: a fast-connecting, high-temperature, high-current, durable, miniaturized connector, comprising a socket 1, a plug 2 disposed on the socket 1, a connecting component 3 disposed between the socket 1 and the plug 2, and auxiliary connection / disconnection components 4 disposed on both sides of the plug 2. The auxiliary connection / disconnection components 4 include auxiliary support blocks 40 respectively disposed on both sides of the plug 2, and an inclined surface 41 disposed on the auxiliary support blocks 40, the inclined surface 41 being inclined away from the socket 1.

[0025] This application provides a miniaturized connector for rapid insertion / disconnection in high-temperature environments with high current, durability, and long service life. It includes a socket, a plug mounted on the socket, a connecting component between the two, and auxiliary insertion / disconnect components on both sides of the plug. The auxiliary insertion / disconnect components include auxiliary support blocks on both sides of the plug and inclined surfaces tilted away from the socket. This application saves installation space through its compact structural design, adapts to highly integrated chip testing scenarios, and contributes to system miniaturization. By utilizing the inclined surfaces and auxiliary support blocks to form a force point, operators can quickly insert and disconnect the connector without tools, solving the problem of cumbersome disassembly and assembly, and adapting to the needs of frequent substrate replacement and aging chamber use. The connecting component ensures the stability of the mechanical connection at high temperatures, and works with internal contacts to achieve a stable supply of high current, while also improving the durability of the locking structure and avoiding the risk of loosening. It effectively extends service life, reduces maintenance costs, and is simple in structure, easy to operate, and has low implementation costs, making it easy to promote and implement.

[0026] In actual operation, when inserting the plug into the socket, the operator's fingers or tools can rest against the inclined surface of the auxiliary support block. Because the inclined surface is tilted away from the socket, the applied force is decomposed into a force perpendicular to the inclined surface and a component force pointing towards the socket. This component force serves as the driving force for insertion, achieving effortless and precise insertion. The auxiliary support block not only provides a point of application, but its symmetrical structure on both sides also guides the plug during insertion, ensuring precise alignment of the plug and socket's connecting components and preventing insertion damage due to misalignment.

[0027] In practice, the socket's fixed end is soldered onto the chip test substrate, while the plug's free end connects to a high-temperature cable, drawing power from the outside and supplying it to the chip through the socket. Auxiliary support blocks on both sides of the plug facilitate insertion and disconnection, allowing for quick replacement of the chip test board.

[0028] In this embodiment, the tilt angle of the inclined surface 41 relative to the socket 1 is defined as A, and A satisfies the following relationship: 45°≤A≤60°.

[0029] In this embodiment, the plug 2 includes a first housing 20 and a plug portion 21 disposed on the first housing 20. The material of the first housing 20 is polyphenylene sulfide.

[0030] In this embodiment, the socket 1 includes a second housing 10 and a slot 11 disposed on the second housing 10. The plug-in part 21 can be matched and inserted into the slot 11. The material of the second housing 10 is polyphenylene sulfide.

[0031] In this embodiment, the connecting component 3 includes connecting seats 30 at both ends of the socket 1, connecting holes 31 on the connecting seats 30, and connecting posts 32 at both ends of the plug 2 located at corresponding positions on the connecting seats 30. The connecting posts 32 can be matched and extended into the connecting holes 31.

[0032] In this embodiment, the connecting component 3 further includes connecting grooves 33 at both ends of the socket 1, and the connecting seat 30 is matched and disposed in the connecting grooves 33.

[0033] In this embodiment, the connecting component 3 further includes guide sleeves 34 disposed on both sides of the plug 2. The guide sleeves 34 are disposed on the outer periphery of the connecting post 32 to guide the connecting post 32 into the connecting hole 31.

[0034] In this embodiment, a limiting plate 35 is also provided on the outer periphery of the connecting post 32. The limiting plate 35 can abut against the inner wall of the guide sleeve 34 to restrict the connecting post 32 from moving away from the guide sleeve 34.

[0035] In actual implementation, when the plug approaches the socket, the guide sleeves 34 on both sides of the plug first contact the connectors 30 at both ends of the socket. The guide sleeves 34 are fitted around the outer periphery of the connecting posts 32, and their inner walls form guide channels, precisely guiding the connecting posts 32 to the front of the connecting holes 31 on the connectors 30, preventing collisions or wear between the connecting posts and connecting holes due to alignment deviations. Guided by the guide sleeves 34, the connecting posts 32 at both ends of the plug smoothly insert into the connecting holes 31 of the connectors 30, completing the initial mechanical connection between the plug and the socket. Simultaneously, the connectors 30 on the socket are pre-installed in the connecting grooves 33, which fix and position the connectors 30, ensuring that the connectors do not shift during assembly and further improving the docking accuracy. A limiting plate 35 is provided around the outer periphery of the connecting posts 32. When the connecting posts 32 are fully inserted into the connecting holes 31, the limiting plate 35 abuts against the inner wall of the guide sleeves 34. When the connecting posts move away from the socket, the limiting plate 35 also abuts against the inner wall of the guide sleeves 34.

[0036] In this embodiment, the connecting post 32 includes a post body 320 and a handle portion 321 disposed on the end of the post body 320 away from the plug 2. The cross-sectional diameter of the handle portion 321 is larger than the cross-sectional diameter of the post body 320.

[0037] In actual use, the outer periphery of the handheld part is provided with anti-slip texture.
