Description

Technical Field

[0001] The invention belongs to the field of communication technology, and in particular relates to a curved adapter for connecting cables. Background Art

[0002] RF connectors, components connected to RF coaxial cables or installed on communications equipment, primarily facilitate connections between communications equipment or RF coaxial cables. Existing curved RF connectors typically use a method of welding the conductors at both ends, with the outer shell leaving an opening for welding the inner conductor. This welding scheme often results in poor performance after the finished product is assembled into a cable assembly, with high standing wave and insertion loss values, seriously affecting signal transmission performance.

[0003] Furthermore, the current industry's curved adapters are single-purpose and incapable of connecting cables. Instead, they generally employ a straight-weld, integrated structure that matches one cable connector to another. Because the inner conductors between the connector and cable are often connected by direct welding, and the outer conductors are often connected by welding the cable shield to the outer conductor, any repairs to the cable-connector connection require repairing the entire connector, or even scrapping the entire main connector. Furthermore, the structural dimensions of the cable-connecting tail portion of the connector are determined by the dimensions of the connecting cable. Each connector model has unique structural dimensions and cannot be adjusted arbitrarily. Summary of the Invention

[0004] In response to the above technical problems, the present invention provides a curved adapter for matching cables. It adopts a new structure to solve technical problems such as poor applicability of matching cable connectors, complex maintenance, and non-interchangeability of adapters and connectors. The bushings and screw sleeves can be loaded and unloaded through the matching accessories at the rear of the adapter to achieve mutual conversion between the adapter and the connector, which significantly improves the convenience, maintainability and multi-specification of the matching cable curved adapter.

[0005] The present invention solves the above problems through the following technical means:

[0006] A curved adapter for connecting cables includes an outer conductor, an insulator, an inner conductor, an insulating sheet and a bushing, wherein: the outer conductor is a curved tube structure, the interior of the outer conductor is hollow to form a mounting cavity, and the insulator is arranged inside the mounting cavity; the shape of the inner conductor is adapted to the shape of the outer conductor, and is fixed on the axis of the mounting cavity by the insulator, and the two ends of the inner conductor are respectively provided with a female jack and a male pin; the insulating sheet is arranged in the end step hole of the outer conductor and is adjacent to the jack of the inner conductor; the bushing is installed in the end step hole of the outer conductor through the outer step and is adjacent to the insulating sheet.

[0007] Preferably, one end of the outer conductor is provided with an installation screw sleeve for installing a cable through an external thread, and the other end of the outer conductor is provided with a connecting screw sleeve for connecting to a socket housing through a clamping ring.

[0008] Preferably, the insulators are divided into transverse insulators and vertical insulators, and a 45° fitting slope is provided between the transverse insulators and the vertical insulators.

[0009] Preferably, the central step hole of the bushing is sleeved on the cable, the shielding layer of the cable is welded to the bushing and then integrally installed in the end step hole of the outer conductor, and the core of the cable is inserted into the jack of the inner conductor.

[0010] Preferably, the number of the insulating sheets is one or more, and the insulating sheets are provided with a central hole and a plurality of symmetrically arranged circumferential holes. The central hole is used to accommodate the core of the cable, and the circumferential holes are used to increase the air medium.

[0011] Preferably, the inner step of the mounting screw sleeve is used to limit the outer step of the bushing.

[0012] Preferably, the outer conductor is made of stainless steel.

[0013] Preferably, the inner conductor is made of beryllium copper.

[0014] Preferably, the outer conductor and the inner conductor are L-shaped structures.

[0015] Preferably, the method further comprises a washer disposed between the inner conductor insertion hole and the outer step of the bushing.

[0016] The invention provides a curved adapter for connecting cables, which has the following beneficial effects:

[0017] (1) The present invention realizes the mutual conversion between the adapter and the connector by adding a detachable bushing and a screw sleeve as accessories to the tail of the adapter, which significantly improves the convenience, maintainability and multi-specification of the cable bending adapter.

[0018] (2) The present invention can change the size of the detachable bushing at the rear of the connector, so that the same connector can be matched with cables of different specifications, thereby improving applicability.

[0019] (3) The present invention adopts a plug-in connection structure to connect the inner conductor of the connector and the inner conductor of the cable. The structure of optimizing the electrical performance of the transmission part of the connector to the best state remains unchanged. It only needs to adjust the size of the tail accessory bushing to match the cables of different specifications. The use of a plug-in connection method can reduce welding and improve the convenience of assembly. If the size of the inner conductor of the cable is smaller than the size of the inner conductor of the tail of the connector, a single pin of suitable size is used to match the tail of the inner conductor of the cable and then directly connect it to the inner conductor of the connector, thereby improving the convenience of the connector structure.

[0020] (4) The present invention uses a curved inner conductor for integral assembly, which not only reduces standing wave and insertion loss values, improving production efficiency and yield rate, but also reduces radio frequency leakage and insertion loss. In addition, the housing is made into an integral piece, which is compact and occupies little space. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figures 1 to 2 As shown, the curved adapter for connecting cables includes an outer conductor 1, an insulator 2, an inner conductor 3, an insulating sheet 4 and a bushing 5. In the figure, the outer conductor 1 is a curved tube structure, the interior of the outer conductor 1 is hollow to form a mounting cavity 101, the insulator 2 is arranged inside the mounting cavity 101, the shape of the inner conductor 3 is adapted to the shape of the outer conductor 1, and is fixed on the axis of the mounting cavity 101 by the insulator 2. The inner conductor 3 is respectively provided with a female jack 301 and a male pin 302 at both ends. In this embodiment, the outer conductor 1 and the inner conductor 3 are L-shaped structures.

[0031] Specifically, the insulator 2 is divided into a horizontal insulator 201 and a vertical insulator 202, with a 45° fitting bevel provided between the horizontal insulator 201 and the vertical insulator 202. The jack 301 has a split-slot closing structure. In this embodiment, the outer conductor 1 is made of stainless steel, and the inner conductor 3 is made of beryllium bronze.

[0032] It should be noted that a stepped hole is provided at the end of the outer conductor 1, and one or more insulating sheets 4 are provided in the end stepped hole. The insulating sheet 4 is adjacent to the insertion hole 301 of the inner conductor 3. The bushing 5 is installed in the end stepped hole of the outer conductor 1 through the outer step 501 and is used to squeeze and fix the insulating sheet 4.

[0033] Example 2

[0034] like Figures 1 to 3 As shown, one end of the outer conductor 1 is provided with a mounting screw 6 for mounting the cable 8 via an external thread 102, and the other end of the outer conductor 1 is provided with a connecting screw 7 for connecting to the socket housing via a retaining ring 103. Specifically, the central stepped hole of the bushing 5 is sleeved over the cable 8. The shielding layer of the cable 8 is welded to the bushing 5 and then integrally mounted within the terminal stepped hole of the outer conductor 1. The core of the cable 8 is inserted into the jack 301 of the inner conductor 3.

[0035] Specifically, the inner step 601 of the mounting screw sleeve 6 is used to limit the outer step 501 of the bushing 5 .

[0036] During specific implementation, one or more washers may be provided between the insertion hole 301 of the inner conductor 3 and the outer step 501 of the bushing 5 .

[0037] It should be noted that this embodiment uses a plug-in connection structure to connect the connector inner conductor and the cable inner conductor. The structure that optimizes the electrical performance of the connector transmission portion to the optimal state remains unchanged. Only the size of the rear accessory bushing needs to be adjusted to match cables of different specifications. The use of a plug-in connection method can reduce soldering and improve assembly convenience. If the size of the cable inner conductor is smaller than the size of the connector rear inner conductor, a single pin of the appropriate size is used at the rear of the cable inner conductor and then connected to the connector inner conductor through a plug-in connection, which improves the convenience of the connector structure.

[0038] Furthermore, the use of curved inner conductors for integral assembly not only reduces standing wave and insertion loss, improving production efficiency and yield, but also reduces RF leakage and insertion loss. Furthermore, the integrated housing is compact and takes up little space.

[0039] Example 3

[0040] like Figure 4 As shown, there are one or more insulating sheets 4, each having a central hole 401 and multiple symmetrically arranged circumferential holes 402. The central hole 401 is used to accommodate the core of the cable 8, while the circumferential holes 402 are used to increase the air dielectric. The circumferential holes 402 are used to increase the air dielectric and ensure that the insulating sheet 4 has a certain deformation margin to ensure sufficient contact between the bottom of the inner conductor and the core.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
