Abstract
The utility model discloses a radio frequency leakage prevention SMP double-female adapter which comprises a jack, an insulator, a shell, a shielding ring and a bushing, wherein the insulator consists of two identical sections, the jack, the insulator and the shell are fixed from inside to outside through pouring sealant, the bushing is respectively arranged outside the pouring holes at the left end and the right end of the shell, and the shielding ring is arranged on the outer circle of a contact head at the left end and the right end of the shell. According to the utility model, the metal bushing is used for wrapping the casing hole, so that the radio frequency leakage is reduced, and the isolation of the adapter is improved; the stepped shielding ring is arranged at the contact head part, so that the inserting clearance is reduced after the shielding ring is inserted into the SMP-J connector, the shaking prevention effect is achieved, and the shielding effect is achieved. The utility model can improve the shielding efficiency from-65 dB to more than-80 dB, and has simple operation and high reliability.
Description
Technical Field
The utility model relates to the technical field of connectors, in particular to an SMP double-female adapter capable of preventing radio frequency leakage.
Background
The SMP series products are small push-in radio frequency coaxial connectors, have the characteristics of small volume, light weight, good anti-seismic performance, wide working frequency band, certain axial and radial mutual insertion inaccuracy and the like, and are suitable for occasions of modularized dense installation. The pouring sealant has good fixity, and the use of the pouring sealant for fixing the inner conductor, the insulating medium and the outer conductor is a fixing method commonly used in the connector industry, but radio frequency signal leakage to a certain degree is inevitably caused due to the existence of a pouring hole, and meanwhile, certain radio frequency signal leakage is also caused due to the certain floatability of the SMP connector and the certain gap existing between the inserted parts after the male head and the female head are inserted oppositely.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to an SMP double-female adaptor with radio frequency leakage prevention to solve the above technical problems.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a prevent SMP double-yin adapter of radio frequency leakage, includes jack, insulator, shell, shielding ring, bush, the insulator comprises two sections identical, jack, insulator, shell are fixed through the casting glue by interior and outside, install the bush outside the both ends embedment hole about the shell respectively, install the shielding ring on the contact excircle at both ends about the shell.
Preferably, the outer surface of the shielding ring is provided with a stepped structure.
Compared with the prior art, the utility model has the following advantages: according to the utility model, the metal bushing is used for wrapping the casing hole, so that the radio frequency leakage is reduced, and the isolation of the adapter is improved; the stepped shielding ring is arranged at the contact head part, so that the inserting clearance is reduced after the shielding ring is inserted into the SMP-J connector, the shaking prevention effect is achieved, and the shielding effect is achieved. The utility model can improve the shielding efficiency from-65 dB to more than-80 dB, and has simple operation and high reliability.
Drawings
FIG. 1 is a block diagram of an SMP double female adaptor of the present invention that is resistant to radio frequency leakage.
In the figure: 1. jack, 2, insulator, 3, shell, 4, shielding ring, 5, bush, 6, and pouring sealant.
Detailed Description
The utility model is explained in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1, a SMP double-female adaptor capable of preventing radio frequency leakage comprises a jack 1, an insulator 2, a shell 3, a shielding ring 4 and a bushing 5, wherein the insulator 2 is composed of two identical segments, the jack 1, the insulator 2 and the shell 3 are fixed by a potting adhesive 6 from inside to outside, the bushings 5 are respectively installed outside the potting holes at the left end and the right end of the shell 3, and the shielding ring 4 is installed on the outer circle of the contact head at the left end and the right end of the shell 3. The outer surface of the shielding ring 4 is provided with a step-shaped structure.
After the adapter is inserted into the SMP-J type connector, the insertion gap is reduced, so that the anti-shaking function is realized, the shielding function is realized, and the isolation of the adapter is improved.
The foregoing is a preferred embodiment of the present invention, and it will be apparent to those skilled in the art that variations, modifications, substitutions and alterations can be made in the embodiment without departing from the principles and spirit of the utility model.
