Description

Technical Field

[0001] This utility model relates to electrical connector technology, and in particular to a small-diameter, automation-friendly shielded connector suitable for lightweight, high-density integrated electronic devices. Background Technology

[0002] As equipment in consumer electronics, industrial control, and other fields develops towards "thinner and lighter designs with higher density integration," the size, production efficiency, and reliability of internal electrical connectors have become key limiting factors. Existing shielded connectors suffer from the following core problems in application:

[0003] The contradiction between size and strength: In order to adapt to the miniaturization requirements of equipment, traditional connectors need to reduce the thickness of the metal shell, but this will directly sacrifice mechanical strength (resistance to extrusion and deformation) and destroy the integrity of the shielding structure, resulting in a decrease in electromagnetic interference (EMI) protection performance and failing to meet the electromagnetic compatibility requirements of precision electronic equipment.

[0004] The conflict between structural complexity and reliability: Existing shielded connectors mostly adopt a "discrete metal shell + multi-part assembly" design (such as separate assembly of shell, shield, and locking parts). The large number of parts and complicated assembly process not only increase the risk of structural failure (such as loose parts leading to shield gaps) but also reduce overall reliability.

[0005] Poor adaptability to automated production: Most connector terminals and cables are connected by manual soldering, resulting in low production efficiency and poor quality consistency. Even if some automated processes are adopted, the complex layout of parts (such as multiple positioning structures) makes it difficult to integrate into the automated assembly and testing process of the production line, resulting in high production costs and failing to meet the needs of mass production.

[0006] High cost of shielding solutions: Some connectors achieve shielding and protection through "secondary injection molding and encapsulation", but this solution requires encapsulation of the entire connector, which not only increases material costs, but also covers the main body area of ​​the connector - which is not the optimal solution for scenarios that do not require overall protection and need to maintain the solid feel of the main body (such as handheld device interfaces).

[0007] Therefore, the market urgently needs a connector solution that can simultaneously address the issues of "excessive size, difficulty in automation adaptation, balance between shielding and strength, and controllable cost". Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a small outer diameter automated and user-friendly shielded connector to solve the problems of existing connectors such as "contradiction between size and strength, complex structure and low reliability, difficulty in automation and high shielding cost".

[0009] To achieve the above and other related objectives, the technical solution provided by this utility model is: a small outer diameter connector, comprising:

[0010] A male connector, wherein the insertion end of the male connector is configured as a plug structure and has a male terminal and a female terminal at the end;

[0011] A female connector, wherein the insertion end of the female connector is configured as a socket structure and is provided with a male terminal two and a female terminal two at the end;

[0012] The socket structure corresponds to and matches the plug structure and has a metal shielding structure surrounding the outer periphery of the plug structure; the male terminal one and the female terminal two are correspondingly matched and matched.

[0013] The preferred technical solution is as follows: the end of the plug structure is formed with region one and region two, region two is formed with a slot extending inward along the axial direction relative to region one, female terminal one is disposed in region one, and male terminal one is disposed in region two.

[0014] The preferred technical solution is as follows: the end of the socket structure is formed with region three and region four, region four is formed with a plug extending outward along the axial direction relative to region three, male terminal two is disposed in region three, and female terminal two is disposed in region four.

[0015] The preferred technical solution is that the outer periphery of the plug structure has multiple sets of convex ribs arranged at equal angles and extending along the axial direction, and the end of the convex ribs near the plug end is provided with a guide slope.

[0016] A preferred technical solution is that an annular groove is formed on the outer periphery of the plug structure, and a sealing ring is provided in the annular groove.

[0017] The preferred technical solution is that the metal shielding structure is composed of a metal ring embedded in the peripheral wall of the socket structure, or a metal layer formed by electroplating on the peripheral wall of the socket structure, or a metal layer formed by spraying on the peripheral wall of the socket structure.

[0018] The preferred technical solution is that the first male terminal, the second male terminal, the first female terminal, and the second female terminal are all crimp terminals.

[0019] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0020] Miniaturization: By providing both male and female terminals on the male end and corresponding female and male terminals on the female end, the problem of "excessive terminal spacing and difficulty in reducing the outer diameter" caused by the traditional female end only having female terminals is avoided; combined with the compact division of the plug / socket area, the final installation outer diameter of the connector is reduced compared to the traditional solution, perfectly adapting to the needs of thin and light devices.

[0021] Automation: The terminals adopt a crimping structure, which can realize the integrated connection of terminals and cables through high-speed precision automatic crimping machines, improving production efficiency and quality consistency. At the same time, the connector only includes four types of core components: male / female terminals, terminals, metal shielding structure, and sealing ring. The assembly process is simplified and can be directly integrated into automated assembly and testing on the production line, significantly reducing production costs.

[0022] Balancing shielding and strength: The metal shielding structure surrounds the plug structure, forming a complete and continuous shielding cavity, avoiding the shielding gaps of discrete structures, thus improving electromagnetic interference (EMI) protection performance; if an embedded metal ring solution is adopted, the mechanical strength of the socket structure can also be enhanced simultaneously, completely resolving the contradiction between "size reduction and strength / shielding".
