Abstract
The utility model discloses a grounding device of a radio frequency connector. The grounding device comprises the radio frequency connector (1) and a cavity (3). A gasket (2) is arranged between the radio frequency connector (1) and the cavity (3) and is made of a purple copper foil. An outer semiconductor of the radio frequency connector (1) is in interference fit with the inner hole wall of the cavity (3). Due to the fact that the gasket is made of the purple copper foil, the grounding device has good conductivity, thermal conductivity and malleability to enable the radio frequency connector to be stressed and pressed to produce micro transformation easily and enable contact to be close and reliable. The radio frequency connector (1), the gasket (2) and the cavity (3) are in interference fit. The grounding device has low requirement for machining tolerance, is simple to assemble and disassemble and easy to locate and ensures batch production pass percent.
Description
Technical field
The utility model relates to a kind of radio frequency connector, particularly a kind of radio frequency connector earthing device.
Background technology
Along with the raising of mobile network quality, the device intermodulation is required also to improve thereupon, and device radio frequency connector ground connection is reliable very large to the stability influence of intermodulation, a high-quality radio-frequency devices must have a reliable earthing method of cover to carry out ground connection to ensure.
Existing radio frequency connector earthing device mainly contains three kinds.The one, outer conductor is threaded, and this kind ground connection is more reliable, but needs inner core to separate with medium and outer conductor, thus cause assembling complicatedly be difficult to guarantee the precision of assembling.Its inner core and resonant column can not adopt and be welded to connect (being difficult to stressed), and be if inner core and main rod spin with screw thread, easily stressed and loosening because rotating when the final assembly coupling.The 2nd, outer conductor and cavity carry out interference crimping mode, and this kind earthing device is also more reliable, but adopt disposable crimping, and be non-dismountable, inapplicable in a lot of occasions.The 3rd, outer conductor screw crimping, this kind earthing device is the most frequently used mode, it is convenient, simple to operate to change, but the reliability of ground connection is unstable, easily because contacting the inhomogeneous intermodulation that affects.
The utility model content
The technical problem that will solve of the present utility model is to provide a kind of radio frequency connector earthing device that overcomes the existing apparatus defective, and it is simple in structure, easy disassembling, reliability are high.
Solve the problems of the technologies described above in order to solve, the utility model radio frequency connector earthing device comprises radio frequency connector, cavity, be provided with pad between radio frequency connector and described cavity, the material of pad is red copper foil, and radio frequency connector outer conductor and cavity inner hole wall gap coordinate.
As a kind of preferred version, the thickness of pad is less than or equal to 0.3mm more than or equal to 0.1mm.
As another preferred version, the inner hole wall gap of the outer conductor of radio frequency connector and cavity more than or equal to 0, is less than or equal to 0.2mm.
With respect to existing radio frequency connector earthing mode, adopt the radio frequency connector earthing device of said structure to have following beneficial effect: the one, install the thin pad of a slice additional between radio frequency connector and cavity, gasket material is red copper foil, good conductivity is arranged, thermal conductivity, ductility easily produces little distortion above making that radio frequency connector is stressed and being pressed in and contacts closelyr, also more reliable, is equivalent to be coated with between radio frequency connector and cavity the rubber cushion that one deck can conduct electricity and elasticity is large.The 2nd, processing and matching requirements are reduced, because the assembly relation between radio frequency connector, pad and cavity three is matched in clearance, so the requirement to machining tolerance is lower, the flatness, roughness, the depth requirements that are no matter flatness, roughness, height and the cavity endoporus of radio frequency connector outer conductor can downgrade, dismounting is also simpler, more easily locate, thus the qualification rate of assurance batch production.

Fig. 2 is the cutaway view of the utility model radio frequency connector earthing device;
Fig. 3 is the partial enlarged drawing of A part in Fig. 2.
Embodiment
radio frequency connector earthing device of the present utility model such as Fig. 1, shown in 2 and 3, main body radio frequency connector 1 adopts screw fastening mode commonly used, but the ground connection of radio frequency connector 1 does not adopt the flange face of outer conductor and cavity 3 directly to coordinate, but install the thin pad of a slice 2 additional between radio frequency connector 1 and cavity 3, the material of this pad 2 is red copper foil, THICKNESS CONTROL is between 0.1mm to 0.3mm, and radio frequency connector 1 outer conductor and cavity 3 inner hole wall gaps coordinate, clearance control is between 0 to 0.2mm, just radio frequency connector can be compressed red copper foil during urgent screw like this, produce reliable ground connection.
The utility model is that ground connection is reliable, changes conveniently, and is simple to operate, and several characteristics can well merge than the distinguishing feature of other radio frequency connector earthing mode; Another distinguishing feature is the innovation of earthing material and earthing mode, other radio frequency connector earthing mode is all that the radio frequency connector outer conductor contacts with the direct of cavity, the relative this patent of brass and aluminium alloy red copper foil used is all harder, and conductivity, ductility are all poor; Another the utility model radio frequency connector earthing mode used is that the mode that adds transition zone (dielectric layer) between outer conductor and cavity realizes, apparatus structure is simple.
Claims (3)
1. radio frequency connector earthing device, comprise radio frequency connector (1), cavity (3), it is characterized in that: be provided with pad (2) between described radio frequency connector (1) and described cavity (3), the material of described pad (2) is red copper foil, and described radio frequency connector (1) outer conductor and described cavity (3) inner hole wall gap coordinate.
2. radio frequency connector earthing device according to claim 1, it is characterized in that: the thickness of described pad (2) is less than or equal to 0.3mm more than or equal to 0.1mm.
