Abstract
The utility model discloses a kind of electric shock resistant plug; including shell, power line and inserted sheet; the front end of the inserted sheet is provided with the insulation protective jacket that length is 5mm 15mm; using plug of the present utility model during outside extract; intermediate plate on socket can depart from rapidly with contact chip and be contacted with insulation protective jacket; so as to just cut off circuit when plug is not pulled out completely, avoid user's finger and blade contact and cause electric shock, improve the security that plug uses.
Description
Technical field
It the utility model is related to electric connector technical field, and in particular to a kind of electric shock resistant plug.
Background technology
Plug is one of power supply connecting device being most widely used in actual life, and it mainly includes shell, metal is inserted
Piece and power line, after metal insert inserts socket, circuit realizes conducting, easy to use, but is inserted when needing to extract
During head, because metal insert has larger length, circuit is in the conduction state all the time before it does not thoroughly extract socket, finger
Electric shock accidents occurs may go through the gap between plug and socket and blade contact during pulling the plug out of the socket, therefore
Its security has much room for improvement.
Publication No. CN204130761U Chinese utility model patent discloses a kind of safety on January 28th, 2015 and inserted
Head, including plug and inserted sheet, the inserted sheet are arranged on the lower end of the plug body, and the construction of the inserted sheet from outside to inside is followed successively by
Insulating barrier and conductive layer, the lower end of the inserted sheet are provided with the tactile ear of elasticity, and the centre of the tactile ear of elasticity is connected with conductive layer, described
The both sides of the tactile ear of elasticity encase the inserted sheet, and the tactile ear of elasticity can extend after receiving pressure along the inserted sheet direction；This practicality
New inserted sheet outer layer has insulating barrier parcel completely, causes electric shock accidents to prevent child and powered blade contact, improves
The security of plug.
The content of the invention
Present in prior art, the defects of finger easily causes electric shock with blade contact when pulling the plug out of the socket, this reality
A kind of electric shock resistant plug is disclosed with new, plug described in the utility model can break in advance during the socket of extraction
The circuit between inserted sheet and socket intermediate plate is opened, so as to avoid human body and powered blade contact, improves the security of socket.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of electric shock resistant plug, including shell, inserted sheet and power line, it is characterised in that：The inserted sheet is included before being arranged at
The connection sheet at end and the contact chip for being arranged at rear end；Insulation protective jacket is provided with the connection sheet；The insulation protective jacket
Length is 5mm-15mm.
Anti-slop serrations are provided with the connection sheet outer surface.
The connection sheet is step or taper.
The outer surface of the insulation protective jacket and the flush with outer surface of contact chip.
The thickness of the insulation protective jacket is 0.5mm-1mm.
The insulation protective jacket is made up of PVC plastic
The insulation protective jacket passes through hot injection molding.
Compared with prior art, the utility model has the advantages that：
1st, inserted sheet front end of the present utility model be connection sheet, rear end be contact chip；Insulation is provided with the connection sheet to protect
Sheath, the length of the insulation protective jacket is 5mm-15mm；During outwards pulling the plug out of the socket, the intermediate plate on socket can be rapid
Depart from contact chip and contacted with insulation protective jacket, so as to just cut off circuit when plug is not pulled out completely, avoid using
Person's finger and blade contact and cause electric shock, improve the security that plug uses.
2nd, the outer surface of connection sheet of the present utility model is provided with anti-slop serrations, improves and connects between insulation protective jacket and connection sheet
The fastness connect, avoid that relative displacement occurs between insulation protective jacket and connection sheet, reduce the security of plug.
3rd, connection sheet of the present utility model is step or taper, the outer surface of insulation protective jacket and the appearance of contact chip
Face is concordant, ensures that plug smoothly can extract and insert socket, improves the comfortableness of practicality.
4th, the utility model is searched the use PVC plastic of book insulation protective jacket and is made, and its thickness is 0.5mm-1mm, ensures exhausted
The insulating capacity of edge protective case, improve the security used；Simultaneously by thickening the thickness of insulation protective jacket, insulation protection is avoided
Set is excessively abraded, and extends the service life of insulation protective jacket.
5th, insulation protective jacket of the present utility model is connected by way of hot injection molding with connection sheet, and it is strong to improve connection
Degree, avoid that relative displacement occurs, improve the security of plug.

Embodiment
Below will the utility model is described in further detail by specific embodiment：
Embodiment 1
The present embodiment most preferred embodiment new as this adaptation, it discloses a kind of electric shock resistant plug, as shown in figure 1,
Including shell 1, inserted sheet and power line 2, the inserted sheet includes the connection sheet 3 for being arranged at front end and the contact chip 4 for being arranged at rear end,
The contact chip 4 is connected with power line 2；Insulation protective jacket 5 is provided with the connection sheet 3；The length of the insulation protective jacket 5
For 5mm.
Anti-slop serrations 6 are provided with the outer surface of connection sheet 3.
As shown in Fig. 2 the connection sheet 3 is step.
The outer surface of the insulation protective jacket 5 and the flush with outer surface of contact chip 4.
The thickness of the insulation protective jacket 5 is 0.5mm.
The insulation protective jacket 5 is made up of PVC plastic
The insulation protective jacket 5 passes through hot injection molding.
Embodiment 2
The length of insulation protective jacket described in the present embodiment is 15mm.
As shown in figure 3, the connection sheet is taper.
The thickness of the insulation protection bar is 1mm.
Operation principle of the present utility model：When a plug is to be inserted into the socket, the intermediate plate in socket contacts with the full section of contact chip,
So as to realize the conducting of circuit, when needing to pull the plug out of the socket, socket intermediate plate can just depart from when plug is not pulled out with contact chip
