Abstract

The utility model discloses an insulation terminal for an outlet box of an explosion suppression motor. The insulation terminal comprises a binding post and an insulation connecting sleeve sleeved on the binding post, wherein a locating base is convexly arranged on the outer wall of the insulation connecting sleeve, and a plurality of installing holes are arranged in the locating base. According to the insulation terminal, the insulation terminal is connected and fixed with the outlet box of a motor by using a bolt through the installing holes in the locating base; and compared with the traditional connecting structure, the insulation terminal has the advantages of being simple in structure, lowering production cost, being more stable during installation and fixation, and effectively improving safety property of the motor.

Description

A kind of explosion-proof motor outlet box is used insulated terminal
Technical field
The utility model relates to a kind of insulated terminal, and especially a kind of explosion-proof motor outlet box is used insulated terminal.
Background technology
At present, for the stable and safety of threephase asynchronous work, the flame-proof type threephase asynchronous is generally realized being electrically connected of motor and external equipment through the motor outlet box is installed.Chinese patent Granted publication CN2899253; May 9 2007 Granted publication day; Patent name is for disclosing a kind of motor outlet box in " a kind of motor outlet box "; Include junction box seat, connector cover, and some insulated terminals, the faying face of junction box seat and connector cover is the diagonal plane of motor outlet box.As shown in Figure 1; This figure is the structural representation of conventional motors outlet box; Wherein traditional insulated terminal comprises insulation adapter sleeve 1a and the binding post 2a that is connected on the insulation adapter sleeve 1a, and the end that insulation adapter sleeve 1a goes up away from binding post 2a convexes with gulde edge, the outlet box 3a inwall setting that reclines of this gulde edge; Also comprise being used for gulde edge is pressed on the pressure strip 4a on the 3a wall in the outlet box, this pressure strip 4a and outlet box 3a inwall respectively from both sides the clamping and positioning limit and each other bolt be connected.This pressure strip 4a is the cast iron structure; Through tight fixed bolt that it is fixing with outlet box 3a; Though this structure is firm; But because pressure strip 4a is the cast iron structure, thus when gulde edge compresses mutually on pressure strip 4a and the adapter sleeve 1a that insulate, need be on adjacent outlet box 3a inwall on the gulde edge and pressure strip 4a place pad asbestos pad.In addition, because pressure strip is an electric conducting material, in order to guarantee the high-voltage motor creepage distance, also need increase the length of insulation adapter sleeve 1a, the length direction of insulation adapter sleeve is consistent with axially.
Summary of the invention
In order to overcome the deficiency of prior art, it is a kind of simple in structure, with low cost that the utility model provides, and effectively improves the explosion-proof motor outlet box of motor security performance and use insulated terminal.
The utility model solves the technical scheme that its technical problem adopted: a kind of explosion-proof motor outlet box is used insulated terminal; Comprise binding post and be socketed on the insulation adapter sleeve on the binding post; Convex with positioning seat on the outer wall of said insulation adapter sleeve, offer some installing holes on this positioning seat.
Further be set to: said positioning seat distributes around insulation adapter sleeve excircle.
Adopt technique scheme, positioning seat is positioned at the same plane that radially belongs on the insulation adapter sleeve, guarantees when the insulation adapter sleeve is connected with motor outlet box bolt more stable thus.
Further be set to: said positioning seat is positioned at the medium position of insulation adapter sleeve length direction.
Adopt technique scheme, the medium position of this insulation adapter sleeve length direction is the flame proof junction, and that the positioning seat that is positioned at this flame proof joint can improve the assembling of insulating between adapter sleeve and motor outlet box is stable.
Further be set to: the quantity of said installing hole is three, and installing hole axially evenly distributes around the insulation adapter sleeve.
The employing technique scheme, the most preferred number of installing hole is three, three installing holes are realized fixing between positioning seat and outlet box through bolt, stablizing when this technology has not only guaranteed the insulated terminal installation, but also reduced production cost.
Further be set to: be provided with plurality of strengthening ribs between said positioning seat and insulation adapter sleeve outer wall.
Adopt technique scheme, mainly consider the strength problem of insulating material, the situation of insufficient strength can appear in the connecting portion between positioning seat and insulation adapter sleeve, and reinforcement can address this problem.Wherein, the preferred amount of reinforcement is three, and simultaneously, reinforcement evenly is provided with around insulation adapter sleeve excircle, further improves the intensity effect of reinforcement.
The beneficial effect of the utility model is: insulated terminal is connected fixing through the installing hole of positioning seat with motor outlet box bolt; Traditional relatively syndeton, this structure is not only simple in structure, has reduced production cost; And more stable when installing and fixing, effectively improve the security performance of motor.
Description of drawings
Fig. 1 is the structural representation of conventional motors outlet box.
Fig. 2 is the insulate structural representation of adapter sleeve of the utility model embodiment.
Fig. 3 is the vertical view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Like Fig. 2, shown in 3; Present embodiment comprises the binding post (not shown) and is socketed on the insulation adapter sleeve 1 on the binding post; The medium position of length direction is the flame proof junction on the insulation adapter sleeve 1; This flame proof junction is provided with the ripple male and fomale(M&F) near the excircle of binding post, and this ripple male and fomale(M&F) plays the creepage distance effect of lengthening electrified body.Simultaneously, this flame proof junction convexes with the positioning seat 2 that distributes around insulation adapter sleeve 1 excircle, offers three on this positioning seat 2 around insulation adapter sleeve 1 axial equally distributed installing hole 21.
Insulation adapter sleeve 1 is threaded with binding post, and binding post and the 1 coaxial setting of insulation adapter sleeve.Insulation adapter sleeve 1 is provided with screw, and the end of binding post is provided with external screw thread, and thus, insulating to constitute between adapter sleeve 1 and binding post is threaded.
Also be provided with three reinforcements 3 between positioning seat 2 and insulation adapter sleeve 1 outer wall, reinforcement 3 evenly distributes around insulation adapter sleeve 1 excircle.
In the utility model, insulated terminal is connected fixing with motor outlet box bolt through the installing hole 21 on the positioning seat 2, traditional relatively syndeton; This structure is not only simple in structure; Reduce production cost, and more stable when installing and fixing, effectively improved the security performance of motor.
