Abstract
The utility model belongs to a low voltage explosion-proof electrical field, and in particular relates to a terminal bias open distribution explosion-proof motor connecting box. The connecting box is mainly characterized in that the distribution mode of connecting terminals of the existing low voltage explosion-proof motor connecting box is improved; six connecting terminals are in bias open arrangement; the distance between head and tail connecting terminals and a middle connecting terminal is greater than the distance between other connecting terminals; two temperature measurement terminals are arranged beside a lead port; grounding bolts are arranged on the outer sides of two temperature measurement terminals; an inner cavity space of the improved connecting box is effectively used; a GB3836 specification is met; the size is reduced; and the manufacturing cost is reduced.
Description
Technical field
The utility model belongs to low-voltage explosion-proof technical field of electricity, relates to flame-proof electric motor terminal box, and specifically a kind of terminal deflection is opened distributed flame-proof electric motor terminal box.
Background technology
Existing low-voltage explosion-proof motor connecting cartridge, as the terminal box of YB series, six binding posts in box, its mutual alignment is arranged and is adopted concentric circles mode to distribute, five binding posts be take middle part binding post as the center of circle, first, two binding posts in end are arranged on lead wire outlet one side, line is vertical corresponding with lead wire outlet central axis, distance between six binding posts is completely equal, in terminal box, a side is also provided with earth stud and two thermometric terminal (see figure 1)s, press the regulation of GB3836, between binding post live part, between live part and non-live part and and inwall between spacing must be greater than the distance of regulation, while being 1140V as rated voltage, must be greater than 18mm, and six binding posts are concentric circles, distribute too concentrated, and earth stud is arranged on a side, cause the intracavity space of terminal box rationally not utilize, cause terminal box overall dimension larger, the defect that manufacturing cost is high.
Summary of the invention
Inventor is in being engaged in for many years the production and operating activities of low-voltage explosion-proof electrical equipment, find that existing low-voltage explosion-proof motor connecting cartridge exists certain defect, through investigation, explore and improve, object is to provide a kind of terminal deflection to open distributed flame-proof electric motor terminal box, technical solution problem preferably, overcomes the defect of existence.
Technical solution adopted in the utility model is that a kind of terminal deflection of design is opened distributed flame-proof electric motor terminal box, its structure comprises: low-voltage explosion-proof motor connecting cartridge, box wall, installing hole, six binding posts, earth stud, two thermometric terminals, lead wire outlet, wherein, with lead wire outlet for before just, six binding post mutual alignments are deflection and open shape distribution setting, middle part binding post invariant position, take middle part binding post as axle center, by head, two binding posts in end are together with second, the 3rd, clockwise or the counterclockwise acute angle deflection of the 4th binding post, first, distance between two, end binding post and middle part binding post is greater than first binding post and second binding post, second binding post and the 3rd binding post, the 3rd binding post and the 4th binding post, distance between the 4th binding post and last binding post and middle connecting terminal and the 3rd binding post, two thermometric terminals are arranged on lead wire outlet side, earth stud is arranged on a side of two thermometric terminals.
The utility model adopts technique scheme, existing low-voltage explosion-proof motor connecting cartridge is improved, due to six binding posts are distributed by the original concentric circles that is, change deflection into and open shape distribution setting, and the modulation in addition of the spacing between pair of wire connection terminals, earth stud is arranged on to thermometric terminal one side, thereby changed binding post, mutual alignment between thermometric terminal and earth stud, terminal box intracavity space is utilized effectively, meeting under the prescribed condition of GB3836, terminal box inner chamber is reduced, overall dimension reduces, manufacturing cost reduces.
