Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a radio frequency signal miniature connector. Background Technology

[0002] With the development of communication technology, the integration level of modules is becoming increasingly higher, and the size of various microwave communication devices, mobile communication devices, and precision testing instruments is becoming increasingly miniaturized and micro-sized. RF connectors are connectors used to transmit RF signals, often serving to connect substrates or RF modules to substrates.

[0003] Traditional RF connectors typically employ a plug-receptacle structure. A plug is soldered onto one substrate, and a receptacle onto the other. The plug and receptacle are then inserted to achieve electrical conductivity between the two substrates. However, the relatively large size of the plug and receptacle contributes to a bulky overall module structure, making it unsuitable for use in miniaturized devices. To address this, another type of RF connector has emerged. This type uses an insulating sleeve around a conductor, with both ends of the conductor soldered or crimped to the substrates on either side to achieve conductivity. However, existing RF connectors of this type also have some drawbacks:

[0004] 1. Although connectors using welding can connect and fix the conductor to the two substrates, the small size of the connector makes welding difficult, which makes the installation process more complicated and affects the assembly efficiency.

[0005] 2. Although the crimp connector is relatively easy to install, the conductor and the substrate make hard contact. If vibration or shaking occurs during use, the contact point between the conductor and the substrate may shift, resulting in poor contact and affecting signal transmission. Utility Model Content

The shell is a hollow tubular structure, the insulator is disposed inside the shell, and the outer side wall of the insulator abuts against the inner side wall of the shell. An axial mounting hole is provided inside the insulator, and the conductive component is connected to the axial mounting hole.

Conductive elements are respectively provided at both ends of the elastic element, extending out of the end face of the insulator, and the conductive elements are limited and connected to the insulator.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figure 1-3As shown, a radio frequency (RF) signal miniature connector includes a housing 1, an insulator 2, and a conductive assembly coaxially arranged. The housing 1 is a hollow tubular structure. The insulator 2 is fixedly installed inside the housing 1, with its outer sidewall abutting against the inner sidewall of the housing 1. An axial mounting hole 21 is provided inside the insulator 2, and the central axis of the axial mounting hole 21 coincides with the central axis of the insulator 2. The conductive assembly is connected to the axial mounting hole 21. The housing 1, as the overall support component of the RF signal miniature connector, can be made of a rigid material to ensure sufficient rigidity. The insulator 2 isolates the conductive assembly from other conductors, preventing short circuits and improving operational stability. The insulator 2 can be made of insulating materials such as rubber or ceramic. The conductive assembly connects two substrates or RF modules, enabling signal transmission between them.

[0026] The conductive component includes an elastic element 3, which is made of conductive material. The elastic element 3 is disposed in the axial mounting hole 21. Conductive elements 4 are respectively disposed at both ends of the elastic element 3. The conductive elements 4 extend out of the end face of the insulator 2 and are limitedly connected to the insulator 2.

[0027] During use, the RF signal miniature connector is placed between two substrates or RF modules, so that the two conductive elements 4 are respectively connected to the contacts of the two substrates or RF modules, and the conductive elements 4 can appropriately compress the elastic element 3; thus, through the reaction force of the elastic element 3, the conductive elements 4 can make stable contact with the contacts of the substrates or RF modules, reducing the problem of displacement of the conductive elements 4 due to vibration and other factors; during operation, the RF signal can be transmitted between the two substrates or RF modules through the conductive elements 4 and the elastic element 3.

[0028] During use, the conductive element 4 and the substrate of this RF signal miniature connector adopt an elastic contact conduction method, which not only avoids the trouble of soldering and reduces the assembly difficulty, but also improves the assembly efficiency. At the same time, the elastic element 3 can provide a certain buffer force to avoid the problem of loosening and displacement caused by hard contact, thus improving the stability of the connector operation.

[0029] To improve structural stability, two limiting steps 22 are provided within the axial mounting hole 21, and limiting bosses 41 are provided on the outer wall of the conductive member 4. The limiting bosses 41 can abut against the corresponding limiting steps 22. Under normal circumstances, under the elastic force of the elastic member 3, the two limiting bosses 41 can be pushed to abut against the corresponding limiting steps 22, thereby limiting the conductive member 4 through the limiting steps 22 and preventing the conductive member 4 and the elastic member 3 from falling out of the axial mounting hole 21. During use, the conductive member 4 can slide within the axial mounting hole 21 by pressing it against the substrate or RF module, thereby compressing the elastic member 3, and the reaction force of the elastic member 3 will limit the contact between the conductive member 4 and the substrate or RF module.

[0030] For ease of manufacturing, in this embodiment, the insulator 2 includes a first part 23 and a second part 24 with identical structures, which are mirror images of each other within the housing 1. By dividing the insulator 2 into two parts, it is easier to install the elastic element 3 and the conductive element 4 into the axial mounting hole 21, thus improving assembly convenience. In other embodiments, the two parts of the insulator 2 may have different structures; as long as the two parts can separate the axial mounting hole 21, it is convenient to assemble the conductive element 4 and the elastic element 3. On the other hand, in other embodiments, the insulator 2 may also be a single integral component.

[0031] To improve structural stability, a protective sleeve 5 is fixedly installed inside the axial mounting hole 21. The protective sleeve 5 is fixedly connected to the first part 23 and the second part 24, and both ends of the protective sleeve 5 abut against the limiting step 22 inside the axial mounting hole 21. The conductive member 4 and the elastic member 3 are respectively disposed inside the protective sleeve 5, and the conductive member 4 slides against the side wall of the protective sleeve 5. The first part 23 and the second part 24 can be connected and fixed through the protective sleeve 5, and the limiting step 22 limits the protective sleeve 5, thereby connecting and fixing the two parts of the insulator 2, and also limiting and fixing the protective sleeve 5 inside the insulator 2.

[0032] In this embodiment, the elastic element 3 is a metal spring; in other embodiments, the elastic element 3 may also be other elastic devices or structures such as a sheet made of conductive material.

[0033] The insulator 2 is provided with grounding springs 6 at both ends, and the grounding springs 6 are respectively connected to the outer shell 1. When using the radio frequency signal miniature connector, the grounding springs 6 are used for grounding, so that the outer shell 1 is grounded as a whole, making the outer shell 1 a shield for shielding signals, realizing the function of shielding electromagnetic signals, reducing the interference of external electromagnetic signals on the connection and conduction of the conductive element 4, and improving the stability of signal transmission.

[0034] Specifically, each end of the insulator 2 is provided with a mounting step surface 25, and the grounding spring 6 is respectively attached to the mounting step surface 25, and the grounding spring 6 abuts against the side wall of the insulator 2 and the inner side wall of the outer shell 1. By setting the mounting step surface 25, the installation position of the grounding spring 6 can be positioned, and the grounding spring 6 abuts against the insulator 2 and the outer shell 1 respectively, thereby limiting and fixing the grounding spring 6 on the mounting step surface 25, so that the grounding spring 6 can be connected and limited to the outer shell 1, thus improving the stability of the structure.

[0035] In this embodiment, multiple grounding claws 61 are arranged in a circular array on the grounding spring 6. By setting multiple grounding claws 61, it can be adapted to the usage requirements of different installation positions, thereby improving the convenience of installation. At the same time, multiple grounding points can also be achieved through multiple grounding claws 61, so that the grounding spring 6 can be stably grounded, thereby improving the stability of operation.

[0036] In this embodiment, the grounding claw 61 and the grounding spring 6 are integrally formed. In other embodiments, the grounding claw 61 and the grounding spring 6 can also be two independent components, which can be connected and fixed together by welding, snap-fitting or other methods.

[0037] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
