The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of waterproof DC charging head comprising:
Shell, the shell is interior to have an installation cavity, and the installation cavity extends transversely through the shell, and circumferential on its inner wall
It is provided with a circle boss；
Needle is connected, is provided with the plastic pad being adapted to the installation cavity on the connection needle, the connection needle is from the peace
The one end behaveing affectedly is inserted into and is fixed in the installation cavity by the cooperation of the inner wall of the plastic pad and the installation cavity；
Sealing ring, the outer diameter of the sealing ring be adapted to the installation cavity and press in the plastic pad and the boss it
Between.
Preferably, the plastic pad is plastic products.
Preferably, the internal diameter of the sealing ring is adapted to the connection needle.
Preferably, the connection needle includes linkage section and construction section, the diameter of the construction section is greater than the connection
The diameter of section has stepped hole be adapted to the construction section and the linkage section on the plastic pad and passes through the stepped hole
And it is sheathed on the connection needle.
Preferably, the internal diameter of the sealing ring is adapted to the linkage section.
Preferably, the plastic pad is riveted in the installation cavity.
Preferably, the plastic pad is riveted on the connection needle.
Preferably, the outside of the shell is circumferentially arranged limit floor.
The beneficial effects of the utility model are: the utility model is by being arranged a sealing ring in the inside of DC charging head, it is close
Sealing property is more preferable, and waterproofness is stronger, and appearance is more beautiful.And in the outside of DC charging head be arranged limit floor replace it is traditional recessed
Slot, circlip optimize structure design, can reduce production cost, human cost, improve production efficiency, practical.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is traditional structure schematic diagram.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Usually here in attached drawing description and
The component of the utility model embodiment shown can be arranged and be designed with a variety of different configurations.Therefore, below to attached
The detailed description of the embodiments of the present invention provided in figure is not intended to limit the range of claimed invention,
But it is merely representative of the selected embodiment of the utility model.
Referring to Figures 1 and 2, the utility model discloses a kind of waterproof DC charging head comprising:
Shell 1, the shell 1 is interior to have an installation cavity, and the installation cavity extends transversely through the shell 1, and on its inner wall
Circumferentially it is provided with a circle boss；
Needle 4 is connected, is provided with the plastic pad 2 being adapted to the installation cavity on the connection needle 4, the connection needle 4 is from institute
It states one end insertion of installation cavity and the installation cavity is fixed on by the inner wall cooperation of the plastic pad 2 and the installation cavity
It is interior；
The outer diameter of sealing ring 3, the sealing ring 3 is adapted to the installation cavity and presses in the plastic pad 2 and described convex
Between platform.
Since DC charging head needs to carry out the plug of plug at work, in order to avoid connection needle 4 is by the related extraction of plug,
As shown, set linkage section 402 and construction section 401 for the connection needle 4 in the present embodiment, the construction section 401 it is straight
Diameter is greater than the diameter of the linkage section 402, has on the plastic pad 2 and is adapted to the construction section 401 and the linkage section 402
Stepped hole and be sheathed on the connection needle 4 by the stepped hole.Linkage section 402 is set to be inserted into installation cavity forward simultaneously
The sealing ring 3 is abutted to plastic pad 2.In this way, plastic pad 2 is limited by sealing ring 3 and boss when choosing plug, installation
Section 401 is limited by plastic pad 2, to avoid connection needle 4 by related extraction.The linkage section 402 is used for banjo, and installs
Section 401 is then attached for the circuit with electrical appliance.
Further, the plastic pad 2 is first riveted on connection needle 4, is riveted in installation cavity again later.And it is corresponding to it
, the internal diameter of the sealing ring 3 is adapted to the linkage section 402, to keep and connect the sealing between needle 4.
In addition, different two sections of internal diameter are set by the installation cavity in the present embodiment, to be formed for the ease of production
The boss.The outer diameter of plastic pad 2 is adapted to biggish one section of internal diameter in installation cavity.Also, the outside of the shell 1 is circumferentially
It is provided with limit floor 5, the specific structure of the limit floor 5 can reasonably be changed according to the actual situation, such as be changed to edge
Multiple retention beads of shell 1 being circumferentially arranged etc..
Since the main structure of DC charging head belongs to the content that the prior art is covered, and the improvement of the utility model is simultaneously
It is not directed to, such as the elastic slice 6 cooperated in shell 1 with the connection needle 4, is not repeated in the present embodiment.
The utility model being arranged using the above structure, by the way that a sealing ring 3, leakproofness is arranged in the inside of DC charging head
Can be more preferable, waterproofness is stronger, and appearance is more beautiful.And it is known in the industry as row, plastic pad 2 is plastic products, passes through the plastic cement
Pad 2 abuts sealing ring 3, and installation is more stable, will not cause to damage to connection needle 4, shell 1.Also, after compressing plastic pad 2
By judging that the exposed junction of plastic pad 2 can decide whether that, equipped with sealing ring 3, there is no the risk of neglected loading, processing quality is high.This
Outside, in the outside of DC charging head, setting limit floor 5 replaces traditional groove 7, circlip 8, optimizes structure design, can reduce life
Cost, human cost are produced, production efficiency is improved, it is practical.
Above-described embodiment is the preferred embodiment of the utility model, and the utility model can also have other embodiments.Ability
The technical staff in domain can also make equivalent deformation or replacement without departing from the spirit of the present invention, these equivalent changes
Type or replacement are all contained in range set by the claim of this application.
