Embodiment
Referring to figs. 1 through Fig. 3, the utility model ammeter box is described further with hub slot embodiment.
A kind of ammeter box hub slot, the madial wall of described hub slot 1 convexes with for the erection column 2 through electric wire 3, described erection column 2 inside are provided with stepped hole 21, described stepped hole 21 is provided with sealing gasket 22, described erection column 2 inside are also provided with the snap ring 23 for securing electric lines 3, depart from ring 24, metallic sheath 25 and columnar lock sleeve 26, described metallic sheath 25 is fixedly connected on the inwall of erection column 2, conflict and be connected with sealing gasket 22 in described lock sleeve 26 one end, the sidewall of described lock sleeve 26 is provided with for forming the spacing conical surface coordinating 261 with metallic sheath 25, the described conical surface 261 is conflicted and is connected with the bottom surface of metallic sheath 25, described disengaging ring 24 is arranged in snap ring 23, described snap ring 23 is nested in lock sleeve 26 inwalls.When electric wire 3 need to be from hub slot 1 during through erection column 2, operating personnel directly insert erection column 2 by electric wire 3 from hub slot 1 inner side laterally, lock sleeve 26 moves to metallic sheath 25 directions under the conflict of sealing gasket 22, the conical surface 261 of the bottom surface conflict lock sleeve 26 of metallic sheath 25 makes stressed towards axis direction of lock sleeve 26, thereby drive snap ring 23 to lock electric wire 3, therefore make hub slot 1 there is the function of securing electric lines 3, avoid electric wire 3 easily in hub slot 1, to be pulled out out; When will more rewiring 3 time, only need press and depart from ring 24, the bottom that departs from ring 24 just can outwards strut the blade tooth of snap ring 23 2321, make electric wire 3 depart from the locking of snap ring 23, directly extract just detachable electric wire 3, therefore this structure handled easily personnel's wiring is installed, and is conducive to reduce operating personnel's installation difficulty.
Described snap ring 23 comprises the ring body portion 231 being wholely set and the blade tooth portion 232 being made up of some blade tooths 2321, described ring body portion 231 is cylindrical shape, described blade tooth 2321 all, towards the 231 axis direction settings of ring body portion, is provided with blade tooth portion breach 2324 between adjacent blade tooth 2321.Blade tooth portion breach 2324 on snap ring 23 facilitates blade tooth 2321 to arrange towards the axle center of ring body portion 231, is convenient to be departed from ring 24 and struts, and makes snap ring 23 have larger coupling mechanism force; Snap ring 23 is made as to cylindrical shape, guarantees that snap ring 23 can firmly be arranged on erection column 2 inside.
Described ring body portion 231 is made up of some solid sheet 2311, between adjacent solid sheet 2311, be provided with ring body portion breach 2312, described ring body portion breach 2312 quantity are identical with blade tooth 2321 quantity, described blade tooth portion breach 2324 quantity are identical with solid sheet 2311 quantity, described ring body portion breach 2312 extends to blade tooth portion 232, and described blade tooth portion breach 2324 extends to ring body portion 231.In ring body portion 231, be provided with ring body portion breach 2312, using ring body portion 231 also as locking the application of force a part, blade tooth portion breach 2324 on blade tooth 2321 extends to ring body portion 231 simultaneously, ring body portion breach 2312 in ring body portion 231 extends to blade tooth 2321, make snap ring 23 there is the elastic force towards axle center, strengthen the coupling mechanism force of snap ring 23, also made blade tooth 2321 more easily be departed from ring 24 and strut.
Described ring body portion's breach 2312 and blade tooth portion breach 2324 intervals arrange.Coupling mechanism force and the elastic force of snap ring 23 are evenly distributed, and coupling mechanism force is larger, has avoided causing electric wire 3 by blade tooth 2321 crimps because of discontinuity.
Described snap ring 23 forms (it should be noted that, described metal material can be copper product) herein by good springiness, on-deformable metal material.Utilize metal material good springiness, on-deformable feature, after making blade tooth portion 232 repeatedly be strutted, lock by electric wire 3, can also keep higher coupling mechanism force, and be difficult for rupturing, damaging, the mission life-span is long.
