As shown in Figure 1, 2, this is novel to be that a kind of power supply is connected plug configuration, be that the simple and easy convertible insurance fiber tube of a kind of energy uses phase place, have the linking Power supply safety plug structure of repeatedly protection use concurrently, it comprises that seat (2), a linking group (3) and a multicore cartridge fuse (4) etc. are formed in the case (1),, wherein; Case (1) is the colloid insulation structure body of a hollow shape injection mo(u)lding, the leading edge opening, it is closely ccontaining that the inner edge space just can be interior seat (2), leading edge is provided with slightly outstanding catch (11), and in case (1) rim surface right position, offer a saturating slotted eye and the positioning pressuring plate (12) of a movable sliding displacement is set, this positioning pressuring plate (12) rear end recess, be provided with the positioning strip (120) of micro-protuberance shape, in the embedding ditch (13) for engaging case (1) rear end submerged plate inner edge, reach the effect that the location is provided with, and positioning pressuring plate (12) leading portion upper limb right position, the gap slot (121) of invaginated type is set, this gap slot (121) is to cooperate case (1) leading edge catch (11) thickness and establish, and makes positioning pressuring plate (12) when gap slot (121) aligns catch (11), can have the permission space of gap slot (121) angle perk; In seat (2) be the colloid insulation structure body of integrated injection molding, be to cooperate case (1) inner space and establish, its inner rim is provided with for linking group (3) and the ccontaining space of cartridge fuse (4); Linking group (3) is the assembly body of a linking power supply, be provided with two conduction inserted sheets (31) (32) and be connected power line (301) (302), wherein an inserted sheet (32) is adopted the mode that separately is connected power line (302), fixed point U groove (320) is set in inserted sheet (32) termination, and power line (302) end is connected the copper guide card of  shape (33), and the section of arranging in pairs or groups is

Shape colloid insulated top is moved body (34), after making guide card (33) and top move body (34) to combine, also form the connecting groove of a ㄩ shape, and just can a ccontaining cartridge fuse (4) between inserted sheet (32) fixed point U groove (320), make between inserted sheet (32) and power line (302) and be connected, and body (34) is moved on the top can adopt independent setting or directly one-body molded by corresponding right position in the interior seat (2), its lateral margin wall is provided with the outstanding convex arc piece (340) of arcuation, make cartridge fuse (4) termination can compress into the ㄩ shape connecting groove energized line (302) that body (34) and guide card (33) formation are moved in the top, but during this end perk of cartridge fuse (4), must be subjected to convex arc piece (340) influence to produce the phenomenon of slightly outwards moving; Cartridge fuse (4) is the structure body that a multicore fuse and tool use phase place more, as shown in Figure 3, its inside is provided with heterogeneous slot space axle (41), the transparent casing (42) of collocation appearance edge, form the little space of perforation of array independence shape, many group fuse cores can be set respectively in the little space of this independence, and the many groups of order fuse core one end respectively is connected respectively on the conductive junction point (430) of ratchet headgear (43), end then can be connected in a common headgear (44) or another ratchet headgear in addition, make cartridge fuse (4) form the structure body that each core all can be connected power supply and security insurance use separately, and do not hinder the position that is connected power supply in cartridge fuse (4) below, be provided with and lift spring (45) (sign is arranged) on one group in Fig. 2, lift spring (45) one ends on this and can be fixed in the corresponding right position of interior seat (2) inner space, end then keeps the state that support cartridge fuse (4) rises in addition, make cartridge fuse (4) under the situation of no external force, can be and lift spring (45) effect and the phenomenon of generation ratchet headgear (43) rising perk; Overall structure combination setting be with linking group (3) in conjunction with cartridge fuse (4) after, be arranged at the location in the interior seat (2), and interior seat (2) sleeve be incorporated in the inner space of case (1), the group of setting of promptly finishing plug structure body is upright.

At this moment, cartridge fuse in the plug (4) just is under the positioning pressuring plate (12) of case (1), shown in Fig. 4,5,6, on lift spring (45) and be the contraction of being extruded of positioning pressuring plate (12), cartridge fuse (4), the cartridge fuse (4) and positioning pressuring plate (12) also bears down on one, making the ratchet head of cartridge fuse (4) cover into guide card (33) and top moves in the space that body (34) formed, and conductive junction point (430) A contacts in guide card (33), promptly, bring into play the protection effect of safe handling with the fuse core turn-on power of A phase place; When the fuse core of A phase place blows or other factors need be changed when using phase place, can press down by the positioning pressuring plate (12) of case (1) and retire, the fastening state that breaks away from positioning strip (120) and embedding ditch (13), and leading portion gap slot (121) is in case (1) leading edge catch (11) below, this moment, positioning pressuring plate (12) leading portion must stretch out outside the catch (11), be that plug is not as pulling out on socket, catch (11) is when replacing socket, positioning pressuring plate (12) can't be located outer removing by catch (11) and open, but get final product simple and easy carrying out after pulling out the state of plugging together, be to open by mistake the safeguard measure that opens for a kind of know-nothing of avoiding such as child etc., and gap slot (121) is in catch (11) when below, because of positioning pressuring plate (12) lose Ka Ding and on lift spring (45) bounce effect, must make the ratchet headgear (43) of cartridge fuse (4) produce the perk state with positioning pressuring plate (12), as Fig. 7, shown in 8, after ratchet headgear (43) perk, the state that touches that not only breaks away from A phase contact (430) and guide card (33), and move convex arc piece (340) effect of body (34) because of the top, make the perk vertical motion of ratchet headgear (43), the phenomenon that generation outwards moves according to convex arc piece (340), conductive junction point (430) B of ratchet headgear (43) is become to be in directly over guide card (33) apical margin, and positioning pressuring plate (12) is when pressing down once more, cartridge fuse (4) ratchet headgear (43) is vertically moved down, make guide card (33) top touch top conductive junction point (430) B, as Fig. 9, shown in 10, formation is with the state of B phase place fuse core turn-on power, that is action is opened and pressed off to one-time positioning pressing plate (12), made the state of cartridge fuse (4) by A phase place turn-on power, be transformed into the state of B phase place turn-on power, and by the effect of ratchet ratchet relation property, when ratchet headgear (43) conductive junction point (430) B contacts guide card (33), continue to press to the location by positioning pressuring plate (12) again, must make cartridge fuse (4) rotate a phase place according to the ratchet inverse time of ratchet headgear (43); Operation so in regular turn, make in the cartridge fuse (4) each phase place fuse core all can give full play to safe handling, and replacing formality each time, also only open and press off action for one-time positioning pressing plate (12), thoroughly improve and all need dig sled at present at every turn and take out the shortcoming of changing cartridge fuse, but and increased the repeatedly economic efficacy of phase place use of root cartridge fuse multicore one of is not arranged in the past.

In sum, originally novel have above-mentioned good characteristic, though its structure is very simple and easy, can proposes thorough solution at now with the shortcoming of article and the effect that does not reach, and then increase the benefit value of its use.
