Description
Technical field
The utility model relates to a kind of sealed connector, especially a kind of sealing ring during transportation is not easily to fall off
Sealed connector, belongs to technical field of electronic components.
Background technique
Radio frequency connector is electronic component important in present mobile communication network, each in the various environment of mobile communication
Kind of occasion largely uses, wherein sealed connector is since it is with preferable air-tightness and waterproofness, in some outdoor fields
It is widely used in institute.Sealed connector is arranged sealing ring two-by-two between shell, insulator and jack, at the same in order to plate
It is tightly connected, is usually also provided with sealing ring in shell end face, shell end face seal groove is usually straight trough or straight trough dispensing at present, directly
Slot type seal groove sealing ring during actual shipment easily falls off, poor reliability, using sealing ring stationarity after straight trough dispensing
It can get a promotion, but since colloid is affected by temperature greatly, sealing ring is still easy to fall off when hot environment.
Utility model content
Sealing ring is not easily to fall off in simple, at low cost, transportational process that the purpose of the utility model is to provide a kind of structures
Sealed connector.
The utility model is achieved by the following technical programs:
A kind of sealed connector, including shell, insulator and jack, the insulator are co-axially located at shell inner hole
In, the first sealing ring is equipped between insulator and shell inner hole, the jack midfoot support is in insulator inner hole, in the middle part of jack
The second sealing ring is equipped between insulator, shell one end end face is equipped with annular seal groove, and third sealing ring is crimped on described
In annular seal groove；The annular seal groove cross sectional shape be the small inner big swallow-tail form of mouth, annular seal groove two sides respectively with
Shell one end end face forms double barb structures, and third sealing ring is fixed in annular seal groove by double barb structures.
The purpose of this utility model can also be further realized by following technical measures.
Sealed connector above-mentioned, wherein the ring packing groove depth h is 1mm~2mm.
Sealed connector above-mentioned, wherein the annular seal groove two sides angle α is 20 °~30 °.
Sealed connector above-mentioned, wherein the first sealing ring, the second sealing ring and the third sealing ring is O shape
Sealing ring.
Sealed connector above-mentioned, wherein the first sealing ring, the second sealing ring and the third sealing ring is all made of
Rubber is made.
The annular seal groove cross sectional shape of the utility model shell end face uses swallow-tail form, and swallow-tail form two sides and shell
End face forms double barb structures, is not only simple in structure, at low cost, and under double hangnail barrier effects, and sealing ring is not when transport
It easily therefrom falls off, sealing ring fixing-stable is reliable.It is simultaneously that annular seal groove is deep-controlled in 1mm~2mm, and annular seal groove
Two sides angle α is controlled at 20 °~30 °, and the compression ratio of sealing ring and filling rate can not only be made to be in optimum state, enhancing sealing
The sealing effect of circle, moreover it is possible to effectively extend the service life of sealing ring.
The advantages of the utility model and feature will carry out diagram reconciliation by the non-limitative illustration of preferred embodiment below
It releases, these embodiments, is only provided as an example referring to attached drawing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the utility model includes shell 1, insulator 2 and jack 3, insulator 2 is co-axially located in shell 1
Kong Zhong is equipped with the first sealing ring 4 between 1 inner hole of insulator 2 and shell, and 3 midfoot support of jack is in 2 inner hole of insulator, jack 3
The second sealing ring 5 is equipped between middle part and insulator 2,1 right end end face of shell is equipped with annular seal groove 11, third sealing ring 6
It is crimped in annular seal groove 11.Wherein 11 cross sectional shape of annular seal groove is the small inner big swallow-tail form of mouth, annular seal groove 11
Depth h is 1mm~2mm, and two sides angle α is 20 °~30 °, and h is 1.35mm in the present embodiment, and α is 25 °.Annular seal groove
11 two sides form double barb structures 12 with shell right end end face respectively, and third sealing ring 6 passes through double barb structures 12 and is fixed on
In annular seal groove 11.First sealing ring 4, the second sealing ring 5 and third sealing ring 6 are O-ring seals, and are all made of rubber
It is made.
In addition to the implementation, the utility model can also have other embodiments, all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, is all fallen in the protection scope of the requires of the utility model.
