Abstract

A radio-frequency coaxial connector with a threaded sleeve structure is provided with a shell (5), which is connected with a threaded sleeve (6) and welded with the outer conductor of a cable (7) via a weld hole (8), and a hexagonal block (9) and a knurling section (10) are arranged outside a nut (1). The threaded sleeve is screwed into the shell by means of screw threads. The core wire of the cable is welded with a pin (2) also via the weld hole (8). The radio-frequency coaxial connector utilizes the threaded sleeve to protect welded parts, so that welding spots are not easily rusted, moreover, because the part of the connector, which is stressed to bend, is shifted to the cable, the bending frequency of a cable assembly is greatly increased, and the service life of the cable assembly is prolonged. The radio-frequency coaxial connector has the advantages of high reliability, simplicity, quickness, convenient operation and good anti-bending property. Furthermore, because of the combination of the knurling section (10) and the hexagonal block (9), the nut of the connector can be operated by a hand as well as a special spanner, so the radio-frequency coaxial connector can be conveniently installed at any places.

Description

The radio frequency (RF) coaxial connector of screw bushing structure

Technical field

The utility model relates to the radio frequency (RF) coaxial connector of a kind of radio frequency (RF) coaxial connector, particularly a kind of screw bushing structure.

Background technology

Along with the development and the raising of mechanics of communication, the interface unit that its equipment is adopted requires also to improve gradually.What the protected mode of radio frequency (RF) coaxial connector assembly great majority adopted in the past was: the solder connector heel also adds heat-shrink tube, or adopts the welding position of giving connector to add method such as injection moulding plastic sheath and protected.The heat-shrink tube structure is applicable in the common connector that the cable assembly of this structure is more easily from the fracture of connector heel, and solder joint is easily by corrosion, and injection structure needs special injection molding machine and professional mould to guarantee.But for the test cable assembly that is applied under laboratory environment or the critical operation condition, adopt conventional heat-shrink tube structure to be difficult to realize more number of bends, though and the employing injection structure can be from the fracture of connector heel, technical matters complexity, expense are comparatively expensive.

Summary of the invention

The technical problems to be solved in the utility model is for overcoming the deficiencies in the prior art, a kind of radio frequency (RF) coaxial connector that can prevent the screw bushing structure of cable assembly fracture being provided.

Technical solution of the present utility model is:

A swivel nut is connected with shell, is welded to connect by welding hole between the outer conductor of cable and the shell.And outside nut, be provided with six side's platform and knurled segments.

Its further technical scheme is:

Spin by screw thread between swivel nut and the shell.

Also be welded to connect between the heart yearn of cable and the contact pin by welding hole.

The utility model utilizes swivel nut to protect the welding position, solder joint is difficult for by corrosion, and has improved the number of bends of cable assembly because of its stressed crooked position is moved to the cable position greatly, has prolonged the useful life of cable assembly.Its reliability height, simple and fast is convenient to operation, and bending resistance is better.This connector nut adopts annular knurl and six sides coexistence in addition, both can also can operate with special spanner with manual manipulation, can make things convenient for installation anywhere.Because the swivel nut part does not participate directly in the connector electric performance test, thereby makes coaxial connector reach good electric property, realizes stronger mechanical performance.Not only make product have better electrical property, and solved effectively that test cable is less because of bending radius, cable is from phenomenons such as the fracture of connector heel, solder joint corrosions, makes the connector mechanical performance improve, and increased the reliability of connector simultaneously.

Embodiment

This connector mainly is to be made of nut 1 (referring to Fig. 2), shell 5 (referring to Fig. 3), packing ring 3 (referring to Fig. 4), contact pin 2 (referring to Fig. 6) and swivel nut 6 (referring to Fig. 7).Wherein, on shell 5 and contact pin 2, be equipped with welding hole 8.

As shown in Figure 1,, insulator 4 is packed in the shell 5, simultaneously packing ring 3 is enclosed within on the shell 5 in when assembling; Again shell 5 is packed into 1 li on nut and nut 1 is carried out roll riveting make between shell 5 and the nut 1 and can rotate freely and unlikely coming off; Push in the shell 5 after then contact pin 2 and cable 7 heart yearns being welded by welding hole 8; Again cable 7 outer conductors and shell 5 are threaded swivel nut 6 after by welding hole 8 welding simultaneously with shell 5 and promptly finish.

Also can falling in shell 5 terminations along being welded fixing with cable 7 outer conductor junctions.

The purpose that six side's platforms 9 is set on nut 1 and knurled segment 10 is set on the surface is can be with spanner or manual fastening nut, to make things convenient for the assembling of connector.

Claims
