Description

Lock formula safety plug and jack assemblies in 3 holes

Technical field

The utility model be related to a kind of 3 hole lock formula safety plug and jack assemblies, especially one kind can be by powered gold Category is hidden locks formula safety plug and socket group installed in 3 holes of the socket insulation crust back side of panel not reached from the outside Part.

Background technology

At present, known plug, socket be made up of metal insertion cover and metal bolt, straight metal bolt is inserted directly into gold Category sleeve switch on power electricity supply and use equipment operation, it is this be inserted directly into mode exist easily produce loose contact be mistakenly inserted etc. it is hidden Suffer from and easily drop, in order to which contact is good after inserting and stabilization does not drop, metal bolt is all made very long, raw material usage It is many, even prevent that drops also to install screw bolt reinforcing additional.Exposed socket hole can directly see the powered metal in the inside, Powered socket hole is inserted to young and ignorant children with metal object out of curiosity easily to get an electric shockAccident, in order to prevent with gold Category touches socket charged metal sleeve and caused danger, and people do not stint increase cost and individual layer or double shielding are mounted with socket Door, a kind of by the movable part that charged metal sleeve is covered up in exposed socket hole, activity protection door during due to masking It is that thrust from socket hole both sides by spring force to middle close up during plug pins insertion is directly born against on spring But be pressed on protection door side, on inspection time length any protection door it is many damaged to lose charged metal sleeve is covered The effect got up, the socket having for this there is also mounted protection against electric shock smart circuit, be inserted separately into any pole will not get an electric shock but work as When inserting metal simultaneously fire and electric shock accidents still can occur for L, N pole.It is this be inserted directly into conducting, extract disconnection mode, it is all As long as being that can be inserted directly into plug and equally can also be inserted directly into other metalworks easily to occur Danger Electric shock risk, if do not noted with wet Hand plug attaching plug is even more the presence of Danger Electric shock risk.

The content of the invention

In order to overcome existing plug, socket it is this be inserted directly into, extraction mode and the powered gold of socket hole and the inside Thrust when category is straight-through, plug pins are inserted is not the deficiency for directly bearing against on spring but being pressed on protection door side, this practicality Formula safety plug and jack assemblies are locked in a kind of 3 holes of new offer, and formula safety plug is locked in 3 hole and jack assemblies, positioning are protected Protect door and telescopic spring with plug insertion, extract that direction is consistent, straight-through socket hole the inside also without powered metal, be exactly All socket holes are inserted directly into metalwork all without electric shock simultaneously, and also non-contact electric is dangerous for wet hand plug attaching plug, contacts good Well, do not fall out, and save material.

Formula safety plug and jack assemblies are locked in 3 holes of the utility model one kind, and socket includes insulation crust, with terminals The quiet metal contact chip of current-carrying, the quiet metal contact chip of the ground connection with terminals, positioning protection door, spring, bottom plate, 2 with terminals The quiet metal contact chip of piece current-carrying and 1 with the terminals quiet metal contact chip of ground connection are by 60 degree uniform one end through catheter wall installation Hole be arranged on socket insulation crust back side of panel with it is same by 60 degree of uniform plug insertion positions separate 60 degree, the other end and Terminals connection, positioning protection door are connected with spring, spring is on bottom plate.

Formula safety plug and jack assemblies are locked in 3 holes of the utility model one kind, and plug includes front end inserting with target seeker It is head, sealing ring, wire ferrule, 2 carried flow metal contact chips with terminals, the dynamic metal contact chip of 1 with terminals ground connection, tight Gu plug, 2 piece dynamic metal contact chips of the plug head with target seeker, with terminals and the dynamic metal contact of 1 ground connection with terminals Piece is uniformly arranged on target seeker reverse side by 60 degree, and opening a taper to plug end before target seeker center leads directly to threading hole, threading hole Communicated with the dynamic metal contact chip mounting hole with terminals at the target seeker back side, the dynamic metal with terminals in insertion mounting hole In contact chip one end connecting wire, wire sleeve wire ferrule from target seeker hub head end penetrate band taper threading hole insert ends pass, The resistance that wire ferrule is reduced by taper threading hole locks wire, the fastening plug locking of wiring inlet target seeker centre bore.

The beneficial effects of the utility model are that all socket holes are inserted directly into metalwork all without electric shock, socket simultaneously Positioning protection door is consistent with plug insertion, extraction direction with telescopic spring, by plug angle of rotation when service life length, deenergization Degree to insertion hole site, spring drive positioning protection door return, is not required to pulling force plug also can outwards eject automatically, solve directly Insertion pull-out plug mistake breaks the unsafe problems of electric wire, and wet hand plug attaching plug will not also get an electric shock, contact is good, Do not fall out, it is simple in construction, compared the 20%-50% that saves material be inserted directly into pull-out, plug, the socket of phase homogenous quantities.
