Abstract
The utility model discloses a kind of pin protective-cover types to protect plug; each pin on plug sets elastic insulated sheath; elastic insulated sheath is subject to external force and shrinking to allow pin and plug conductive when pin is inserted into socket; pin sets elastic insulated sheath escape groove with plug body intersection, and escape groove can accommodate length of the elastic insulated sheath when working condition is compressed completely.In pin insertion socket process elastic non-conductive sheath pin can be allowed to remain not exposed, accomplish to completely cut off the possibility that pin is contacted with plug user, and reach electrocution-proof protection effect.This protection plug carries out separating the pin that may be got an electric shock using insulating sheath and human contact, electrocution-proof protection effect are guaranteed.
Description
Technical field
The utility model is related to be electrically connected field, a kind of electrical prong structure is referred specifically to.
Background technology
With enriching for social material civilization, more and more electric appliances enter huge numbers of families, and people also more focus on electricity consumption
Safety, present most of attaching plugs are traditional pin bareing plug, can be gone out during insertion socket or extraction socket
Existing one section of charged pin so that user has larger electric shock risk.
Notification number is the Chinese utility model patent of CN206313198U, discloses " a kind of electric shock resistant plug ", passes through
Mounted on plug body front end proof rubber set, plug proof rubber set during plug is made to be close to socket under external force
Surface prevents user's false touch pin and gets an electric shock.It is such to exist by way of being mounted on plug body front end proof rubber set
Defect, since the rubber sleeve for being fixed on case nose substantially completely covers pin when plug is not inserted into socket, thus is made
User cannot see the specific location of pin clearly, and exist quick and precisely to be inserted into socket and influence insulation easy to wear by plug
Effect, appearance and conventional socket differ greatly, and numerous users are difficult to rapidly adapt to, plug manufacturer mold is difficult to adjust and lead
Cause production cost it is more high-leveled and difficult in popularization the problem of.
The content of the invention
In order to overcome in the prior art, user cannot see the specific location of pin clearly, and existing will quick and precisely insert
Head insertion socket and influence insulation effect easy to wear, appearance and conventional socket differ greatly, and numerous users are difficult to quickly
Adaptation, plug manufacturer mold, which are difficult to adjust, causes production cost more high-leveled and difficult in popularizing the defects of using, and the utility model carries
Electrocution-proof protection is carried out using pin dielectric resilience sheath mode for a kind of, elastic insulated sheath is arranged on each pin,
And elastic insulated sheath escape groove is set in header body pin junction.
Technical solution is used by the utility model solves its technical problem：A kind of pin protective-cover type protects plug, bag
It includes：1 plug body, 2 pins, 3 elastic insulated sheaths, 4 elastic insulated sheath escape groove.
A kind of above-mentioned pin protective-cover type protection plug, the plug body are pin and electrical appliance connecting wire and elastic insulated
The fixed structure of sheath, the isolation materials such as plug body generally use makrolon (PC), polyvinyl chloride (PVC).
A kind of above-mentioned pin protective-cover type protection plug, the pin connect conductive media, a usual socket for electric appliance
A whole set of pin is formed by two pins or three pins（Depending on three-pin plug or two-pin plug）, consolidated by plug body
Fixed, pin material is using conductive materials such as brass, copper alloys.
A kind of above-mentioned pin protective-cover type protection plug, the elastic insulated sheath are plug shock preventing protector of electric, bullet
Property insulating sheath one end is connected with plug body, is sleeved on pin, with plug body connecting pin at the escape groove bottom that main body is set
Portion, the other end are movable end, and flexible sheath length when there be not external force effect is concordant substantially with pin and shorter slightly than pin
（About 1 millimeter）Enable it more sturdy and durable under the premise of ensuring safety and user is allowed to see prong position clearly, inserted in plug
When entering socket, the living spring sheath end of pin contact head one end is bonded in socket, as pin is inserted into bullet during socket
Property sheath will be compressed in plug body escape groove to accomplish can to obstruct possibility that pin contacts with user not shadow again
The electric conductivity of pin and socket is rung, elastic insulated sheath cross-sectional shape is identical with pin cross-sectional shape, and making material is not by
Different materials, shape may be employed with use environment, such as：It will be in relatively adverse circumstances using fluorine glue may be employed（KFM）, it is poly-
Tetrafluoroethene（PTFE）Corrugated shape is made etc. heat-resisting, oily and friction material（Main body bullet is compressed to beneficial to elastic insulated sheath
In property insulating sheath escape groove）；And in preferable use environment（In average family）Foam may be employed（Ethyl vinyl acetate
The rubber and plastics hermetic type bubble structure such as ethylene copolymer EVA）Rectangular Elastic sheath is made（Foam has favorable elasticity, without being made
Corrugated can directly punching press foamed cotton plate be made）It greatly reduces cost of manufacture and is beneficial to popularization use.
A kind of above-mentioned pin protective-cover type protection plug, the elastic insulated sheath escape groove is to set plug body portion
One avoidance groove avoids groove location as pin and plug body junction, and depth is to collect elastic insulated sheath compression enough
When length, shape is identical with elastic insulated sheath cross section（Mostly rectangle）, geomery is not interfere elastic insulated sheath
Subject to compression（Elastic insulated sheath is clearance fit with escape groove）.
The beneficial effects of the utility model are that a kind of pin protective-cover type protection plug of the utility model effectively eliminates
Traditional plug is in use（It is inserted into the process of socket）The exposed charged possibility that user is caused to have Danger Electric shock risk of pin or
Existing electric shock resistant plug can not quick and precisely be inserted into use socket, be easily damaged it is big with appearance and traditional plug difference
User is difficult to receive, manufacturer's mold is difficult to adjust, production cost is more high-leveled and difficult in popularizing the defects of using.
Description of the drawings:
Below in conjunction with the accompanying drawings（By taking bipod blade inserting pin plug as an example）The utility model is further illustrated with embodiment.
Fig. 1 is the main schematic diagram of the utility model appearance；
Fig. 2 is along line A-A schematic diagram in Fig. 1；
Fig. 3 is to the schematic diagram of Fig. 1 along line B-B in Fig. 2；
Fig. 4 is the working state schematic representation along line B-B in Fig. 2；
1. plug body in figure, 2. pins, 3. elastic insulated sheaths, 4. elastic insulated sheath escape groove.
