Abstract
The embodiment of the utility model provides an external antenna of an interphone. The external antenna comprises an SMA joint, an inner core wire, a vibrator and a silica gel shell, wherein the front end of the SMA joint is connected with the interphone body, the rear end of the SMA joint is connected with the inner core wire, and the vibrator is sleeved outside the inner core wire and connected with the rear end of the SMA joint; the silica gel shell wraps the SMA joint and the outer part of the vibrator. According to the utility model, the problem that the antenna is damaged or scratched when a user wears the interphone due to the fact that the shell of the interphone antenna is made of the hard rubber material in the related art is solved, and the bending performance of the antenna is improved.
Description
Technical Field
The utility model relates to the technical field of antennas, in particular to an external antenna of an interphone.
Background
The antenna is an important component of the interphone and is used for communication between the interphones. The antenna shell of the existing interphone is mostly made of hard rubber materials such as PC and TPU, so that when a user of the interphone wears the interphone, the user is damaged or scratched by an external antenna.
Disclosure of Invention
The embodiment of the utility model provides an external antenna of an interphone, which at least solves the problem that in the related art, as a shell of the interphone antenna is made of a hard glue material, a user is damaged or scratched by the antenna when wearing the interphone.
According to an embodiment of the present invention, there is provided an interphone external antenna including: an SMA (SubMinengagement version A) joint, wherein the front end of the SMA joint is connected with the interphone body; the inner core wire is connected with the rear end of the SMA joint; the vibrator is sleeved outside the inner core wire and is connected with the rear end of the SMA connector; and the silica gel shell wraps the SMA joint and the outer part of the vibrator.
In one exemplary embodiment, wherein the inner core wire and the rear end of the SMA joint are connected by welding.
In one exemplary embodiment, the vibrator is a spring structure.
In an exemplary embodiment, the silicone shell is integrally formed by a silicone mold.
In one exemplary embodiment, the material of the silicone shell is soft silicone.
In an exemplary embodiment, the vibrator is connected with the rear end of the SMA joint in a riveting mode.
In one exemplary embodiment, the vibrator is connected with the rear end of the SMA joint in a welding mode.
In one exemplary embodiment, the material of the vibrator is metallic copper.
In one exemplary embodiment, the SMA joints are made of a metal material.
In an exemplary embodiment, the front end of the SMA joint is screwed or plugged with the interphone body.
According to the embodiment of the utility model, as the antenna shell of the interphone is made of the soft silica gel material, the flexibility of the interphone antenna is good, the antenna can deform at any angle, the performance of the antenna is not affected, and the problem that a user is damaged or scratched by the antenna when wearing the interphone because the shell of the interphone antenna is made of the hard silica gel material in the related art can be solved.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is a schematic structural diagram of an external antenna of an intercom according to an embodiment of the present invention, and as shown in fig. 1, the external antenna of the intercom includes an SMA joint 1, an inner core wire 2, a vibrator 3, and a silica gel housing 4.
In this embodiment, the front end of the SMA joint 1 may be connected to the interphone body, the inner core wire 2 is connected to the rear end of the SMA joint 1, and the vibrator 3 is sleeved outside the inner core wire 2 and connected to the rear end of the SMA joint 1. And the silica gel shell 4 wraps the SMA joint 1 and the oscillator 3.
In this embodiment, the SMA joint 1 may be made of a metal material, such as copper.
In one embodiment, the SMA connector 1 may include an SMA shell and an SMA jack in the SMA shell, and a front insulator between the SMA jack and the SMA shell, a rear insulator in a rear section of the SMA shell and a rear port, a front end of the SMA jack being used for connecting an inserted external connector pin, a rear section of the SMA jack being riveted with a front end of a spring vibrator inserted into the rear port of the SMA connector, and a front end of the spring vibrator passing through the rear insulator.
In this embodiment, the inner core wire 2 may be connected to the rear end of the SMA joint 1 by welding.
In one embodiment, the vibrator 3 may be made of a metal spring, because the metal spring has high strength, more stable connection signal, longer service life, and reduced antenna length.
In one embodiment, the silicone shell 4 may be made of a soft silicone material and integrally formed by a silicone mold, so that the silicone shell has good flexibility and can deform at any angle without affecting the natural performance.
In the embodiment of the utility model, the antenna can deform at any angle by adopting the soft silica gel material and integrally forming through the silica gel mold, the performance of the antenna is not influenced, the problem that a user is damaged or scratched by the antenna when wearing the interphone due to the fact that the shell of the interphone antenna adopts the hard silica gel material in the related art can be solved, and the bending performance of the antenna is improved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the principle of the present invention should be included in the protection scope of the present invention.
