Abstract
The utility model relates to a kind of three-phase outlet integrated base, comprise A phase first cable cone, B phase first cable cone, C phase first cable cone, the conductor that described A phase first cable cone, B phase first cable cone, C phase first cable cone are all integrated, this A phase first cable cone, B phase first cable cone, C phase first cable cone are directly cast on three-phase outlet integrated base by epoxy resin, form an overall transmission line circuit; Described A phase first cable cone, B phase first cable cone, C phase first cable cone top are flat structure and are connected with cutting blade with isolating switch main shaft; Bottom is that leading-out terminal conductor is for connecting extraneous wire.The beneficial effects of the utility model are: 1, avoid the defect being connected between original structure fixed contact with base conductor and easily loosening; 2, improve insulation level, be applicable to height above sea level and use at 2000m and above area; 3, save cost, substantially increase production efficiency and product qualified rate.
Description
Technical field
The utility model belongs to electrical equipment technical field, and particularly relating to a kind of is Three-phase common-body solid insulation cabinet auxiliary products, with the three-phase outlet integrated base connected for outlet.
Background technology
Conventional structure be three independently part assembly: fixed contact 6 and three-phase integral base 9 and A phase second cable cone 11, B phase second cable bore 12, C phase second cable bores 13.Wherein each fixed contact 6 (totally 3) is fixed on the base conductor 7 of three-phase integral base 9 by the bolt assembly 4 of a M10, A phase second cable cone 11, B phase second cable cone 12, C phase second cable cone 13 are connected with three-phase integral base 9 by watchband-shaped contactor 8, form a transmission line circuit; A phase second cable cone 11, B phase second cable cone 12, C phase second cable are bored between 13 and three-phase integral base 9 and are also needed to come auxiliary seal and insulating effect by silica gel sheath 10.Refer to assembling schematic diagram 1,2.There is following shortcoming in this structure: 1, each fixed contact 6 is connected with the bolt assembly 4 of three-phase integral base 9 by a M10, and it is unreliable that this organization plan connects.Because fixed contact 6 is the operation pivot point of isolating/grounding switch, adopt a bolt fixing easily loosening, be coated with the locking of screw thread glue although can add in screwed hole, life-span of 3000 times or unreliable be born, unreliablely cause heating once loosen will cause to connect and switch is burnt.2, A phase second cable cone 11, B phase second cable cone 12, C phase second cable cone 13 pass through watchband-shaped contactor 8 and are connected with three-phase integral base 9, because many individual overlap joint T-Rings save, cause loop resistance to increase; And it is silica gel sheath 10 auxiliary seals and the insulation of 40mm by height, this structure withstand voltage level is not suitable for high altitude localities and uses.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of and independently assembly part original three, is all integrated into the three-phase outlet integrated base of a product.
The purpose of this utility model has been come by following technical solution.This three-phase outlet integrated base, comprise A phase first cable cone, B phase first cable cone, C phase first cable cone, the conductor that described A phase first cable cone, B phase first cable cone, C phase first cable cone are all integrated, this A phase first cable cone, B phase first cable cone, C phase first cable cone are directly cast on three-phase outlet integrated base by epoxy resin, form an overall transmission line circuit.Described A phase first cable cone, B phase first cable cone, C phase first cable cone top are flat structure and are connected with cutting blade with isolating switch main shaft; Bottom is that leading-out terminal conductor is for connecting extraneous wire.
The beneficial effects of the utility model are: 1, avoid the defect being connected between original structure fixed contact with base conductor and easily loosening; 2, eliminate the link of watchband-shaped contactor and silicon rubber auxiliary seal, improve insulation level, be applicable to height above sea level and use at 2000m and above area; 3, save cost, substantially increase production efficiency and product qualified rate.

Label in accompanying drawing is respectively: 1, cutting blade; 2, isolating switch main shaft; 3, three-phase outlet integrated base; 4, bolt assembly; 6, fixed contact; 7, base conductor; 8, watchband-shaped contactor; 9, three-phase integral base; 10, silica gel sheath; 11, A phase second cable cone; 12, B phase second cable cone; 13, C phase second cable cone; 14, A phase first cable cone; 15, B phase first cable cone; 16, C phase first cable cone.
Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in accompanying drawing 3,4, the utility model comprises A phase first cable cone 14, B phase first cable cone 15, C phase first cable cone 16, the conductor that described A phase first cable cone 14, B phase first cable cone 15, C phase first cable cone 16 are all integrated, this A phase first cable cone 14, B phase first cable cone 15, C phase first cable cone 16 are directly cast on three-phase outlet integrated base 17 by epoxy resin, form an overall transmission line circuit; The advantage of this structure compared with existing structure is: the first, substantially increase production efficiency and product qualified rate.Formerly need produce 4 products: three-phase integral base 9, A phase second cable cone 11, B phase second cable cone 12, C phase second cable bore 13,4 machine configurations, 4 groups of operative employees are needed to produce, a machine configuration one group operation is only needed now to produce, greatly enhance productivity, thus improve production capacity; In addition, the single product qualification rate of A phase second cable cone 11, B phase second cable cone 12, C phase second cable cone 13 is lower, and three-phase outlet integrated base 3 improves in this respect, increases insulation thickness, greatly can improve product qualified rate.The second, eliminate 3 fixed contacts, 6,3 base conductors 7,3 and overlap watchband-shaped contactor 8, copper piece cost can reduce much, although epoxy resin total amount can increase, and the cost that the cost increased is saved far below copper piece.
Described A phase first cable cone 14, B phase first cable cone 15, C phase first cable are bored 16 tops and are flat structure and are connected with cutting blade 1 with isolating switch main shaft 2; Bottom is that leading-out terminal conductor is for connecting extraneous wire.
The utility model is not limited to above-mentioned execution mode; no matter do any change on its shape or material are formed; every employing structural design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection range.
