Abstract
The utility model relates to a British calibration plug housing. The British calibration plug housing comprises an upper cover body and a lower cover body which are jointly buckled through a concave part and a convex part; the concave part and the convex part are respectively arranged on an opening of the upper cover body and the opening of the lower cover body; a plastic pin and two metal pins are vertically arranged on the lower cover body; the plastic pin is longer than the metal pins, so that the two metal pins can be unlocked easily; a first gap beneficial for a power line to pass through is arranged in the opening of the lower cover body; and a second gap is correspondingly arranged in the upper cover body. The British calibration plug housing is reasonable in design, and simple in structure; as the plastic pin for unlocking is arranged, compared with conventional British calibration plug, the British calibration plug housing saves the quantity of the used metal materials, and reduces the cost.
Description
Technical field
The utility model relates to a kind of English rule plug casing.
Background technology
English rule plug is three-pin plug, wherein has long pin to be used for release, and two other metal pin can be smoothly contacted with the interior power supply contact of socket.Yet the release pin of existing English rule plug has also been taken into account the function of ground connection, therefore, most release pin all also makes metalwork, for example the patent No. is: 201120347731.5 disclosed a kind of English rule plugs, comprise plug casing, be fixedly installed a grounding leg and two copper pins on this housing, described copper pin and housing adjacent segment are coated with insulating part, described copper pin forms by pin head, copper bar with as the pin insulating case of insulating part, this insulating case is provided with through hole, the internal diameter of through hole and copper bar external diameter coupling; Described pin head is fixedly connected with the copper bar, and the copper bar passes the pin insulating case and fixes with housing and be electrically connected with corresponding line, described pin insulating case and housing close contact.Although the copper pin that this English rule plugs has adopted adopts the structure of pin head and copper bar, structure relatively in the past, the copper consumption of copper pin has been saved more than 30%, but only need in the plug of release at some, because it does not need ground connection, therefore, the release pin can also be designed to working of plastics, further reduce cost.
Summary of the invention
The purpose of this utility model is to provide a kind of English rule plug casing, and this English rule plug casing is reasonable in design, simple structure, and have plastic pins for release, and relatively traditional English rule plug, cost has been saved in the use of having saved metal material.
The technical solution of the utility model is: a kind of English rule plug casing, comprise upper cover body and lower cover, described upper cover body and lower cover are realized fastening by the jog that is arranged on its opening, be vertically installed with a plastic pins and two metal pin on the described lower cover, the length of described plastic pins is greater than the length of metal pin, in order to being two metal pin releases.
Further, be provided with the first breach that passes in order to power line on the described lower cover opening, correspondence is provided with the second breach on the described upper cover body.
Further, described plastic pins and the lower cover structure that is formed in one, and described plastic pins has for the internal cavity that inserts sheet metal, and with the structural rigidity of reinforced plastics pin, described internal cavity communicates with the inner chamber of lower cover.
Further, described metal pin is comprised of pin head, intermediate plate and the insulating case that is nested with on intermediate plate, and this insulating case is provided with through hole, and the internal face of through hole and intermediate plate outer surface are complementary; Described pin head is fixedly connected with intermediate plate, and intermediate plate passes the pin insulating case and housing is fixed, described pin insulating case and housing close contact.
Further, also be provided with annular protrusion on the described lower cover opening, be provided with the annular groove that cooperates with annular protrusion on the opening of described upper cover body.
Further, be provided with the buckle in the lower cover opening that vertically stretches on the described upper cover body inwall, be provided with on the described lower cover inwall and the clamping floor that is clasped.Locating convex twistings near also being provided with on the upper cover body inwall of the second breach for two of Positioning Power line.
The utility model has the advantage of: the one, this English rule plug casing designs according to British Standard, and reasonable in design, simple structure meets the user demand of Britain; The 2nd, this English rule plug casing has the plastic pins for release, relatively traditional English rule plug, and cost has been saved in the use of having saved metal material; The 3rd, adopt the up and down form of lid fastening, not only when making housing itself, make things convenient for the die sinking manufacturing, and when the assembling internal structure, ease of assembly is enhanced productivity.
