Description
Technical field
This application involves interphone antennas, and in particular to intercom built-in antenna base.
Background technique
Existing antenna base is not easy to assemble, and causes high production cost.
Summary of the invention
The application provides a kind of intercom built-in antenna base convenient for assembling.
According in a first aspect, provided in a kind of embodiment a kind of intercom built-in antenna base, including ontology, insulator with
And PIN needle, ontology one end periphery are equipped with external screw thread, for docking with male connector, the base other end extends to form ring external screw thread
Shape thin slice, the first passage and second channel of connection are additionally provided in ontology, and the diameter value of first passage is less than the diameter value of second channel；
The diameter value at the insulator both ends is less than the diameter value at middle part, and both ends constitute convex shape frustum cone structure, which is set to ontology
The convex shape rotary table of in first passage and second channel and insulator one end is arranged between first passage and second channel, described
It is engaged after annular flake bending with the convex shape rotary table of the insulator other end；Third channel is equipped in insulator, the PIN needle is inserted
In the intracorporal third channel that insulate.
Preferably, the body peripheral is equipped with hex nut.
Preferably, the inner wall of the insulator is equipped at least one groove, and the PIN needle periphery is equipped with and number of recesses phase
Same tapered protrusion portion, the lug boss and groove, which are mutually matched, is arranged in PIN needle in insulator.
Preferably, the wall surface of the recessed third channel of the groove, the groove is by an inclined-plane, a horizontal plane and a vertical plane structure
At horizontal plane is in vertical plane.
Make according to the intercom built-in antenna base of above-described embodiment since insulator both ends are convex shape frustum cone structure
Obtaining the insulator one end may be stuck between the first passage of ontology and second channel, and the other end of insulator can then pass through annular
It is clasped after thin slice bending, insulator is fixed in the body, so as to achieve the purpose that quickly to assemble.Further, in PIN needle
Periphery sets lug boss, and groove is arranged in insulator inner wall, PIN needle is fixed on insulator by the cooperation of groove and lug boss
In, so that the electrical connection of base is relatively reliable.
Detailed description of the invention
Fig. 1 is the exploded view of the application intercom built-in antenna base；
Fig. 2 is the assembling figure of the application intercom built-in antenna base.
Specific embodiment
Below by specific embodiment combination attached drawing, invention is further described in detail.Wherein different embodiments
Middle similar component uses associated similar element numbers.In the following embodiments, many datail descriptions be in order to
The application is better understood.However, those skilled in the art can recognize without lifting an eyebrow, part of feature

Periphery is held to be equipped with external screw thread 11, for docking with male connector, the base other end extends to form annular flake 12 external screw thread 11, this
The first passage 13 and second channel 14 of connection are additionally provided in body 1, the diameter value of first passage 13 is less than the diameter value of second channel 14；
The diameter value at 2 both ends of insulator is less than the diameter value at middle part, and both ends constitute convex shape frustum cone structure, which is set to ontology 1
First passage 13 and second channel 14 in and the convex shape rotary table of 2 one end of insulator be arranged in first passage 13 and second channel
Between 14, it is engaged after the bending of annular flake 12 with the convex shape rotary table of 2 other end of insulator；The is equipped in insulator 2
Triple channel 21, the PIN needle 3 are inserted in the third channel in insulator 2.
In a preferred embodiment, 1 periphery of ontology is equipped with hex nut 15.
In a preferred embodiment, the inner wall of the insulator is set there are two groove 22, the PIN needle periphery be equipped with it is recessed
The identical tapered protrusion portion 31 of slot number, the lug boss 31 and groove 22, which are mutually matched, is arranged in PIN needle in insulator.
In a preferred embodiment, the wall surface of the recessed third channel 21 of the groove 22, the groove is by an inclined-plane, a level
Face and a vertical plane are constituted, and horizontal plane is in vertical plane.
Use above specific case is illustrated the present invention, is merely used to help understand the present invention, not to limit
The system present invention.For those skilled in the art, according to the thought of the present invention, can also make several simple
It deduces, deform or replaces.
