Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Referring to accompanying drawing 1, accompanying drawing 1 is exemplarily described out the security with four interfaces and is inserted.Security insert by: shell 1, inner core 2, unlock button 3, conductor 4 and shell fragment 5 are formed.Wherein shell 1 is processed by engineering plastics, and inner core 2 is processed by engineering plastics, and unlock button 3 is processed by engineering plastics, and conductor 4 is made of copper, and shell fragment 5 is processed by stainless steel.
Referring to accompanying drawing 2, the top of shell 1 is inverted right-angled trapezium, and the bottom is the U font, and wherein, the middle position, top of shell 1 is provided with engaging opening 1a, should recognize that this engaging opening 1a has two, is arranged at respectively on two sides of shell 1; Referring to accompanying drawing 3, the top of shell 1 is provided with rectangular aperture 1b, and shell 1 inner bottom is provided with and holds passage 1c.
Referring to accompanying drawing 4, inner core 2 is inverted right-angled trapezium on the whole, and the middle position, top of inner core 2 is provided with engaging button 2a, is fixed with the opening 1a that engages of shell 1 when being used to assemble; Should recognize that this engaging button 2a has two equally, be arranged at respectively on two sides of inner core 2; In addition, shown in accompanying drawing 1, during nature; The engaging button 2a of inner core 2 is outside overshooting shape, but it has certain elasticity, can inwardly shrink; Referring to attaching Figure 4 and 5, the top of inner core 2 is provided with rectangular protrusions 2b, and after assembling was accomplished, this projection 2b can be connected (referring to accompanying drawing 1) with the opening 1b engaging of shell; Referring to accompanying drawing 5 and 6, inner core 2 also has the lead-in wire macropore 2c and lead-in wire aperture 2d of perforation; Referring to accompanying drawing 6, the inside of inner core 2 has cannelure 2e and transverse groove 2f, and wherein cannelure 2e and transverse groove 2f are vertical relation.
Referring to accompanying drawing 7; Unlock button 3 is the crescent of hollow on the whole; Comprise crescent moon oblique crank Z 3a, be arranged on the pivot 3b at middle part and be arranged on the operating grip 3c of outer end, wherein crescent moon oblique crank Z 3a is right-angled intersection arranged perpendicular (referring to accompanying drawing 1) with pivot 3b and operating grip 3c; In addition, shown in accompanying drawing 1, the exterior periphery of operating grip 3c is provided with projection, conveniently pushes this operating grip 3c.
Referring to accompanying drawing 8, copper conductor 4 form plane (referring to accompanying drawing 1) long limit 4a, form curved concave minor face 4b, be positioned at the bottom and connect U type 4c of portion and the superposed peristome 4d of long limit 4a, minor face 4b.
Referring to accompanying drawing 9, similar with copper conductor 4, shell fragment 5 comprises the long limit 5a, the minor face 5b that forms curved concave that form plane (referring to accompanying drawing 1), be positioned at the bottom and connect U type 5c of portion and the superposed peristome 5d of long limit 5a, minor face 5b; Different with copper conductor 4 is, shell fragment 5 also comprises the upwardly extending inclined-plane 5e that tilts from long limit 5a, and inclined-plane 5e is provided with ligule shell fragment 5f (referring to accompanying drawing 1).
See that from size greater than the size of copper conductor 4, promptly copper conductor 4 can be contained among the shell fragment 5 size of shell fragment 5 on the whole.
Should recognize that the global shape of the global shape of shell 1 and copper conductor 4 and shell fragment 5 is similar, thereby can make copper conductor 4 and shell fragment 5 easily be received in the shell 1.
During assembling, at first, copper conductor 4 is packed in the corresponding shell fragment 5; Wherein, The long limit 4a of copper conductor 4 is corresponding with the long limit 5a of shell fragment 5, and the minor face 4b of copper conductor 4 is corresponding with the minor face 5b of shell fragment 5, and the U type 4c of portion of copper conductor 4 is corresponding with the U type 5c of portion of shell fragment 5; At this moment, the ligule shell fragment 5f on the inclined-plane 5e of shell fragment 5 places on the long limit 4a of copper conductor 4 (referring to accompanying drawing 10); Then, will assemble all-in-one-piece copper conductor 4 and be fit into together in the shell 1 with shell fragment 5, wherein, the U type portion of copper conductor and shell fragment is received into holding in the passage 1c of shell 1, and the inclined-plane 5e of shell fragment 5 is then corresponding to the rectangular aperture 1b of shell 1; Again, the pivot 3b of unlock button 3 is installed in the inner core 2 corresponding transverse groove 2f, at this moment the crescent moon oblique crank Z 3a of unlock button 3 just is installed in the inner core 2 corresponding cannelure 2e; At last, with packing in the shell 1 with the inner core 2 of unlock button 3 assembling, in this process; When the engaging button 2a of inner core 2 touches the side of shell 1, elastic deformation takes place inwardly shrink, after engaging button 2a passes through the engaging opening 1a of shell 1; Outwards eject; The engaging opening 1a of shell 1 and the engaging button 2a of inner core 2 are fixed and are in the same place, and arrive this, and whole assembling process is accomplished.At this moment; The outer end of unlock button 3 (near the part of operating grip 3c) between the rectangular protrusions 2b of the rectangular aperture 1b of shell 1 and inner core 2 (referring to accompanying drawing 1; 10); Because obviously greater than the length (referring to accompanying drawing 3 and 4) of inner core 2, i.e. assembling has obvious gaps after accomplishing to the length of the rectangular aperture 1b of shell 1, so unlock button 3 can move freely between them.
Shown in the security method for using of inserting: when needs are installed lead: the about 15mm of insulating barrier that peels off lead (copper conductor) the end of a thread; Lead-in wire macropore 2c from inner core 2 inserts with lead (copper conductor); Draw from lead-in wire aperture 2d then, all come in contact until the copper core and the copper conductor 4 bilateral (face) of lead.Because stainless steel shell fragment 5 two ends are withstood in shell 1 both sides; Utilize the ligule shell fragment 5f of stainless steel shell fragment 5 that the copper core of lead is fastened; Thereby the copper core that makes lead can both fully contact with minor face 4b with the long limit 4a of copper conductor 4 and fixing; Because the special construction (similar hair fastener type) of copper conductor is compared with the copper conductor that has only on one side (or one side) in the prior art, contact-making surface is bigger, contact is more firm; And the heating in the time of can not occurring using for a long time in the prior art causes the plastic molting problem, thereby has increased fail safe.
When needs are removed lead: with pointing upwards pressing operation handle 3c, make the ligule shell fragment 5f of shell fragment 5 leave the copper core of lead, thereby make the copper core release of lead during dismounting, easily extract lead.
The foregoing description only shows the security with four interfaces and inserts, but should recognize, this is not can also be 2-50 quantity that waits those skilled in the art's anticipation as the restriction to the utility model.
The security of the utility model is inserted rated voltage 24V-1000V, and rated current 1A-200A is suitable for conductor cross-section 0.3mm
2-35mm
2
The utility model is easy for installation, reduces artificial the installation, keep in repair easy, the generation of minimizing fire, electric shock and other safety accidents.
Although above-mentioned explanation by way of example; The best embodiment of the utility model has been described; The protection range of the utility model is not limited in above-mentioned explanation; Persons skilled in the art it is understandable that, under the prerequisite that does not deviate from essence that the utility model instructs and marrow, and any modification and change the protection range that all falls into the utility model.
