AI Technical Summary
然而，现有高频电连接器的绝缘支撑结构在稳固性设计上存在明显不足：传统结构多依赖单一的卡接或螺纹连接方式实现固定，防止在安装时对内部的绝缘支撑结构造成损坏，多数情况下会采用卡接的方式对其安装，而卡接机构的弹性卡块多采用弹簧与卡块的结合进行连接，在高频电连接器长期工作过程中，若使用环境存在温度波动（如工业设备启停时的温差、航空航天场景中的极端温度变化），弹簧的弹性材质会因热胀冷缩产生疲劳形变，尤其在-40℃~150℃的频繁温度循环下，材质内部分子结构逐渐松弛，弹性回复能力大幅下降，进而导致连接时会出现晃动的情况；
本实用新型中，通过稳固机构中，连接器本体底部的稳固板与绝缘卡套内底壁的滑动槽适配，可限制二者在水平方向的相对晃动，同时，导杆活动穿设通孔，橡胶球与通孔外侧的孔圆倒角贴合，且橡胶球能够对稳固板起到限位的作用，减少高频工作或外部轻微碰撞时的结构松动，确保长期使用中连接状态稳定，避免因结构晃动导致的信号传输损耗或接触不良。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-frequency electrical connector technology, specifically to an insulation support structure based on a high-frequency electrical connector. Background Technology
[0002] In fields such as communications, aerospace, and rail transportation, high-frequency electrical connectors are core components for signal transmission. Their connection stability directly determines the operational accuracy and reliability of the entire system. With the rapid development of technologies such as 5G communications, radar detection, and high-frequency testing instruments, high-frequency electrical connectors need to achieve low-loss and highly stable signal transmission under higher frequencies (usually ≥3GHz) and more complex operating conditions. The operating environment of high-frequency electrical connectors is often accompanied by interference factors such as vibration, shock, and temperature fluctuation. For example, the continuous mechanical vibration in the operation of rail transit equipment, the impact load that aerospace equipment bears during take-off and landing, and the frequent external collisions in industrial scenarios will all have a continuous impact on the connection structure of the connector. However, the insulation support structure of existing high-frequency electrical connectors has obvious shortcomings in terms of stability design: traditional structures mostly rely on a single snap-fit or threaded connection to achieve fixation and prevent damage to the internal insulation support structure during installation. In most cases, snap-fit is used for installation. The elastic blocks of the snap-fit mechanism are mostly connected by a combination of springs and blocks. During the long-term operation of high-frequency electrical connectors, if there are temperature fluctuations in the operating environment (such as temperature differences when starting and stopping industrial equipment, extreme temperature changes in aerospace scenarios), the elastic material of the spring will undergo fatigue deformation due to thermal expansion and contraction. Especially under frequent temperature cycles of -40℃ to 150℃, the internal molecular structure of the material gradually relaxes, and the elastic recovery ability decreases significantly, which leads to shaking during connection. Therefore, an insulation support structure based on high-frequency electrical connectors is proposed to address the above problems. Utility Model Content
[0003] The purpose of this invention is to provide an insulating support structure based on a high-frequency electrical connector to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: An insulating support structure based on a high-frequency electrical connector includes a connector body and a protective shell. An insulating sleeve is installed inside the protective shell, and the protective shell is located outside the connecting end of the connector body. A snap-fit mechanism is provided between the insulating sleeve and the connector body, and a stabilizing mechanism is provided inside the insulating sleeve. The snap-fit mechanism includes a connecting plate, an elastic snap block is provided on the outer side of the connecting plate, and a snap groove is provided in the side wall of the connector body; The stabilizing mechanism includes a stabilizing plate, a guide rod fixedly connected to the outer side of one end of the stabilizing plate, a rubber ball fixedly connected to the outer side of the guide rod, a sliding groove fixedly connected to the inner wall of the insulating sleeve, and a through hole opened in the inner wall of one end of the sliding groove.
[0005] As a further optimization of this utility model, the connecting plate is symmetrically and fixedly connected to the outside of the protective shell, and one side of the elastic block is provided with a chamfer.
[0006] As a further optimization of this utility model, the card slots are symmetrically distributed in the side wall of the connector body, and the card slots are adapted to the elastic card blocks.
[0007] As a further optimization of this utility model, the stabilizing plates are fixed and symmetrically distributed at the bottom of the connector body, and one end of the stabilizing plate is flush with one side of the bottom of the connector body.
[0008] As a further optimization of this utility model, the sliding grooves are symmetrically distributed on the inner bottom wall of the insulating sleeve, and the sliding grooves are adapted to the stabilizing plate.
[0009] As a further optimization of this utility model, the guide rod is movably connected inside the through hole, and one end of the guide rod is located outside the through hole.
[0010] As a further optimization of this utility model, the through hole is provided with chamfered edges on both sides, and the chamfered edges on the outer side of the rubber ball sliding groove fit together.
[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the stabilizing mechanism allows the stabilizing plate at the bottom of the connector body to be fitted with the sliding groove on the inner bottom wall of the insulating sleeve, thus limiting their relative swaying in the horizontal direction. At the same time, the guide rod moves through the through hole, and the rubber ball fits into the chamfer of the hole on the outside of the through hole. The rubber ball also acts as a limiter for the stabilizing plate, reducing structural loosening during high-frequency operation or minor external impacts, ensuring stable connection during long-term use, and avoiding signal transmission loss or poor contact caused by structural swaying.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0016] Please see Figures 1-6 This utility model provides a technical solution: The insulating support structure based on the high-frequency electrical connector includes a connector body 2 and a protective shell 1. An insulating sleeve 3 is installed inside the protective shell 1, and the protective shell 1 is located outside the connection end of the connector body 2. A snap-fit mechanism 4 is provided between the insulating sleeve 3 and the connector body 2, and a stabilizing mechanism 5 is provided inside the insulating sleeve 3. The snap-fit mechanism 4 includes a connecting plate 41, an elastic snap-fit block 42 is provided on the outer side of the connecting plate 41, and a snap-fit groove 21 is provided in the side wall of the connector body 2. The stabilizing mechanism 5 includes a stabilizing plate 51, a guide rod 52 is fixedly connected to the outer side of one end of the stabilizing plate 51, a rubber ball 53 is fixedly connected to the outer side of the guide rod 52, and a sliding groove 54 is fixedly connected to the inner wall of the insulating sleeve 3. A through hole 55 is opened in the inner wall of one end of the sliding groove 54.
[0017] It should be noted that: the connecting plate 41 is symmetrically and fixedly connected to the outside of the protective shell 1, one side of the elastic block 42 is provided with a chamfer, and the slots 21 are symmetrically distributed in the side wall of the connector body 2, and the slots 21 are adapted to the elastic block 42. Furthermore: the stabilizing plate 51 is fixed and symmetrically distributed at the bottom of the connector body 2, and one end of the stabilizing plate 51 is flush with one side of the bottom of the connector body 2. The sliding groove 54 is symmetrically distributed on the inner bottom wall of the insulating sleeve 3, and the sliding groove 54 is adapted to the stabilizing plate 51. Specifically: the guide rod 52 is movably connected inside the through hole 55, and one end of the guide rod 52 is located outside the through hole 55. Both sides of the through hole 55 are provided with rounded chamfers 56, which fit into the rounded chamfers 56 on the outside of the sliding groove 54 of the rubber ball 53. As a further implementation of this solution, the protective housing 1 not only serves as the mounting carrier for the insulating sleeve 3, but its material can also be selected according to the usage scenario. In industrial high-impact environments, high-strength aluminum alloy can be used to improve impact resistance. In humid or corrosive environments, it can be upgraded to corrosion-resistant stainless steel or engineering plastics to prevent the housing from rusting and affecting the stability of the internal insulating sleeve 3. In addition to its basic insulation function, the insulating sleeve 3 can be made of materials with lower dielectric loss, such as polytetrafluoroethylene or epoxy glass cloth, according to the transmission frequency requirements of the high-frequency electrical connector, to further reduce the insulation loss of high-frequency signals during transmission, making it suitable for scenarios with extremely high signal transmission accuracy requirements, such as 5G communication and radar equipment. Meanwhile, the chamfered design of the elastic block 42 can be extended to a "double chamfered structure", which not only facilitates the guidance during assembly, but also reduces the frictional wear between the elastic block 42 and the side wall of the slot 21 during disassembly, thus extending the service life of the locking mechanism 4. Workflow: When the insulating support structure based on the high-frequency electrical connector is in operation, the precise docking of each component is first achieved through the assembly process: During assembly, the protective shell 1 with the insulating sleeve 3 is aligned with the connecting end of the connector body 2. Because the elastic block 42 on the outer side of the connecting plate 41 in the snap-fit mechanism 4 has a chamfer on one side, the chamfer will guide the elastic block 42 to produce elastic deformation when it contacts the side wall of the connector body 2. As the protective shell 1 and the connector body 2 gradually approach each other, the elastic block 42 will smoothly slide into the symmetrically distributed slots 21 on the side wall of the connector body 2. The elastic reset characteristic of the elastic block 42 is used to achieve automatic locking, and the initial fixation of the protective shell 1, the insulating sleeve 3 and the connector body 2 is completed. Simultaneously, the stabilizing plates 51 symmetrically distributed at the bottom of the connector body 2 will slide into the sliding groove 54 adapted to the inner bottom wall of the insulating sleeve 3, and the guide rod 52 on the outer side of one end of the stabilizing plate 51 will penetrate into the through hole 55 on the inner wall of one end of the sliding groove 54. The rubber ball 53 on the outer side of the guide rod 52 is elastic and will deform slightly during the insertion process and fit tightly with the chamfer 56 on the outer side of the through hole 55, further strengthening the connection stability of the three. In the subsequent use of the high-frequency electrical connector, the insulating sleeve 3 wraps around the outer side of the connector body 2 connection end, which can effectively block external conductive impurities and moisture, avoid short circuits or leakage problems caused by insulation failure, and reduce the impact of external interference on high-frequency signal transmission. The elastic locking block 42 and the slot 21 of the locking mechanism 4, and the stabilizing plate 51 and the sliding groove 54 of the stabilizing mechanism 5 restrict the relative offset between the connector body 2 and the insulating sleeve 3 from the side and bottom, respectively. The cooperation between the guide rod 52 and the through hole 55 and the elastic compression of the rubber ball 53 can also buffer the vibration caused by high-frequency operation or slight external collisions, avoid signal transmission loss or poor contact caused by structural loosening, and ultimately ensure that the high-frequency electrical connector operates stably under reliable insulation protection and a stable structure.
