Abstract

The utility model relates to the structure of the inner frame body of a plug, comprising at least two embedding grooves used for embedding conductive terminals. The bottom of the embedding grooves or the bottom of the inner frame body is provided with a groove bottom wall block; one side wall of the embedding grooves can be provided with a foldable and movable cover body on the top; the outer end edge of the movable cover body is provided with a lock body; the top part of the other symmetric side wall of the embedding grooves is provided with another corresponding lock body; the groove bottom wall block of the embedding grooves depresses inwards from the front side and the back side of the inner frame body, thus forming a location groove passage which provides the space in which the section parts of the conductor terminals in the front and in the back of a neck section. Therefore, the neck section can depress again to contact with the groove bottom wall block which forms a compact coat to the neck section, thus each outer margin of the conductive terminals can be coated completely and compactly. The utility model also has the advantages of definite location, rapid and stable embedding and good stability in electrifying stability, safe operation and convenience of the apparatus.

Description

Plug inner frame body structure

Technical field

The utility model relates to a kind of plug inner frame body structure that is used for appliance plug.

Background technology

Generally plug is in the life of house, and user demand promotes with the electrical equipment diversification, and the power supply of various electrical equipment mainly is by electric wire and plug receives and biography is fast, and therefore various appliance plugs also are subjected to producing with the developer and further pay attention to.By general appliance plug the plug of two utmost point conducting terminals or three utmost point conducting terminals is arranged, when putting the line operation, earlier heart yearn is placed in the trunking of conducting terminal, again the conducting terminal latter end is being pressed the heart yearn (putting the line operation) of electric wire with terminal press entrainment kenel; Then conducting terminal is inserted in an inner frame body, forms conducting terminal and electric wire in this secondary operations mode and be arranged at inner frame body and form preliminary semi-finished product after fixing, again it is inserted mould, finish one through ejection formation and have the shape of plug box.

See also shown in Figure 1, there is a kind of plug inner frame body structure at present, two embedding slots 11 that provide conducting terminal 15 to set are provided this inner frame body 1 at least, these embedding slot 11 bottom lands, bottom apart from inner frame body is provided with a bottom land wall piece 12, an and sidewall of embedding slot 11, be connected with the Moveable lid body that to destroy or force to yield 13 in the top, the outside ora terminalis of this Moveable lid body 13 is established a buckling body 131, the symmetrical top side wall of another of embedding slot 11 is established a relative buckling body 14 in addition, make Moveable lid body 13 in the state that covers embedding slot 11, the buckling body 131 of its ora terminalis can fasten with relative buckling body 14.Yet this kind commonly used when conducting terminal 15 is planted, because the outer rim of conducting terminal 15, inboard with embedding slot 11 2 sidewalls, the gap that causes fit on easily because the precision of construction easily has flaw, it is the space that conducting terminal 15 still has activity to get loose in embedding slot 11 inside, especially artificially when manual, make conducting terminal 15 produce defective productss easily.This kind situation is all indeterminate by commonly using the location of planting, and it is relatively poor to show stability, therefore is difficult to meet multinational family safety requirements, safety requirementses such as UL, Australia SAA.

The utility model content

The purpose of this utility model provides a kind of embedding slot that increases for more careful, the strong plug inner frame body structure of conducting terminal covering property, steadiness.

For achieving the above object, solution of the present utility model is: a kind of plug inner frame body structure, two embedding slots that provide conducting terminal to set are provided this inner frame body at least, this embedding slot bottom land, bottom apart from inner frame body is provided with a bottom land wall piece, and a sidewall of embedding slot, is connected with the Moveable lid body that can destroy or force to yield in the top, the outside ora terminalis of this Moveable lid body is established a buckling body, and the symmetrical top side wall of another of embedding slot is established a relative buckling body in addition; Wherein this embedding slot bottom land wall piece is caved inward by the forward and backward two side faces of inner frame body, forms a location conduit.

Described embedding slot cell wall apical margin forms an edged surface with gradient to the cell wall inner edge.

Described embedding slot cell wall apical margin is to the cell wall inner edge, and formation one has the edged surface of radian.

After adopting such scheme, because this embedding slot bottom land wall piece, cave inward by the forward and backward two side faces of inner frame body, form a location conduit, the space that the location conduit provides the conducting terminal section portion before and after the cervical part of esophagus to plug, therefore make cervical part of esophagus can sink again to contacting with bottom land wall piece, bottom land wall piece forms careful coating to cervical part of esophagus, therefore conducting terminal is subjected to complete, careful coating in each outer rim, and the location is clear and definite, set fast, but more firm, on the fail safe of stability and electrical equipment use of switching on, convenience, present preferable stability.

Embodiment

See also shown in Figure 2, the utility model is about a kind of plug inner frame body structure, two embedding slots 21 that provide conducting terminal to set are provided this inner frame body 2 at least, these embedding slot 21 bottom lands, bottom apart from inner frame body is provided with a bottom land wall piece 22, an and sidewall of embedding slot 21, be connected with the Moveable lid body that to destroy or force to yield 23 in the top, the outside ora terminalis of this Moveable lid body 23 is established a buckling body 231, the symmetrical top side wall of another of embedding slot 21 is established a relative buckling body 24 in addition, make Moveable lid body 23 in the state that covers embedding slot 21, the buckling body 231 of its ora terminalis can fasten with relative buckling body 24.Wherein:

Please cooperate shown in Figure 3, these embedding slot 21 bottom land wall pieces 22 of the utility model, cave inward by inner frame body 2 forward and backward two side faces, form a location conduit 221, (pressing the forward and backward definition of inner frame body), preceding is when inserting with conducting terminal, with the inner frame body body is the boundary, with the front end of conducting terminal person in the same way, after be when inserting with conducting terminal, with the trunking of conducting terminal in the same way.And embedding slot 21 cell wall apical margins are to the cell wall inner edge, form an edged surface 211 with gradient (perhaps equivalent radian).

The assembling and the advantage explanation of deriving:

See also Fig. 3, cooperate shown in Fig. 4,5, the utility model provides conducting terminal 25 to plant by embedding slot 21, and covers, fixes with 23 pairs of conducting terminals 25 of Moveable lid body.Illustrate further the utility model characteristic part:

When the utility model conducting terminal 25, when inserting embedding slot 21, generally speaking, conducting terminal more than 25 has a recess comparatively, is called cervical part of esophagus 251.And the space that location conduit 221 provides 25 sections portions of conducting terminal (this section portion is with respect to the protruding slightly relatively height of cervical part of esophagus) of cervical part of esophagus 251 front and back to plug, therefore make cervical part of esophagus 251 can sink again to contacting with bottom

land wall piece

22,22 pairs of cervicals part of esophagus of bottom land wall piece 251 form careful coating, therefore conducting terminal 2 is subjected to complete, careful coating in each outer rim, and the location is clear and definite, set fast, but more firm, on the fail safe of stability and electrical equipment use of switching on, convenience, present preferable stability.
