Description
Technical field
The utility model relates to stove technical field of motors, specifically belongs to a kind of stove connection box for motor.
Background technology
Existing stove motor all designs with explosion-proof structure usually, terminal box on stove motor comprises insulating barrier and binding post, the cylindrical of binding post is suppressed with insulating barrier, whole termination is fixed in outlet box support installing hole by bolt by insulating barrier, due to the insulating barrier that bolt junction is step-like, in order to consider bonding strength, the insulating barrier of binding post cylindrical can not be too thick, the cylindrical often suppressing insulating barrier can be less than the largest circumference size of the junction of binding post motor internal, thus binding post is first fixed in outlet box, and then at motor internal, the outlet cable of motor internal and binding post are linked together, and stove with motor operationally, its inside will reach certain vacuum degree, and existing stove motor usually there will be air enters motor internal, vacuum degree is caused to decline, the service behaviour of stove motor is declined.
Utility model content
For the deficiency that prior art exists, it is good that the purpose of this utility model is to provide a kind of sealing, ensures that air can not enter the stove connection box for motor of motor internal by terminal box.
For achieving the above object, the utility model provides following technical scheme: a kind of stove connection box for motor, comprise junction box seat, Binding post/stud, described Binding post/stud to be fixedly arranged on junction box seat and described Binding post/stud is arranged with insulated column, one end of described insulated column is arranged with insulating case, offer seal groove in described insulated column, in described seal groove, be sealedly connected with the first sealing ring.
As preferably, one end that described Binding post/stud is positioned at described junction box seat is connected with binding post, and the junction of described binding post and Binding post/stud is sealedly connected with the second sealing ring.
As preferably, described Binding post/stud is fixedly connected with locking nut relative to the other end of binding post, is also arranged with copper sheathing between described insulating case and described Binding post/stud.
As preferably, described insulating case and described insulated column are made by polytetrafluoroethylmaterial material.
As preferably, described first sealing ring and the second sealing ring are made by hydrogenated nitrile-butadiene rubber.
The utility model has following advantage compared to existing technology: by the first sealing ring be tightly connected between Binding post/stud and insulated column and the second sealing ring be tightly connected between binding post and insulated column; effectively can ensure that the sealing of junction box seat; air will be caused to carry out in motor because of the connecting hole on junction box seat; ensure vacuum degree during dynamo-electric operation; the phenomenon of leaking gas can not be there is, improve the job stability of stove motor; By copper sheathing fixing on insulating case, can ensure that insulating case can be set on Binding post/stud closely, avoid coming off of insulating case.
Accompanying drawing explanation
A kind of stove junction box structure of electrical machine schematic diagram of Fig. 1 the utility model;
A kind of stove connection box for motor cutaway view of Fig. 2 the utility model;
A kind of stove connection box for motor A portion enlarged diagram of Fig. 3 the utility model.
In figure: 1, junction box seat; 11, insulating case; 12, Binding post/stud; 13, connecting hole; 14, insulated column; 15, the first sealing ring; 16, binding post; 17, locking nut; 18, the second sealing ring; 2, motor body.
Embodiment
Be described further referring to figs. 1 through a kind of stove connection box for motor of Fig. 3 utility model embodiment.
A kind of stove connection box for motor, this terminal box is bolted on motor body 2, this terminal box comprises junction box seat 1, Binding post/stud 12, wherein, junction box seat 1 offers the connecting hole 13 for connecting Binding post/stud 12, Binding post/stud 12 to be fixedly arranged on junction box seat 1 and this Binding post/stud 12 is arranged with insulated column 14, insulating case 11 is arranged with in one end of insulated column 14, seal groove is offered in insulated column 14, sealing groove is connected with the sidewall of junction box seat 1, is sealedly connected with the first sealing ring 15 in seal groove; The air that can be ensured outside junction box seat 1 by the sealing ring 15 be tightly connected between wiring screw rod and insulated column 14 can not carry out in junction box seat 1 from connecting hole 13, and then ensure that vacuum degree in motor body 2, make motor operationally gas leak phenomenon can not occur, improve the stability of machine operation.
Further optimization such scheme, the Binding post/stud 12 being located at the inside of junction box seat 1 is connected with binding post 16, the second sealing ring 18 is sealedly connected with between this binding post 16 and insulated column 14, can be sealed by butted line cassette holder 1 further by the second sealing ring 18 be tightly connected between binding post 16 and insulated column 14, avoid entering of gas, improve the sealing of junction box seat entirety 1.
Further optimization such scheme, to be threaded locking nut 17 relative to the other end of binding post 16 at Binding post/stud 12, also copper sheathing is arranged with between insulating case 11 and Binding post/stud 12, the insulating case 11 on Binding post/stud 12 can be made so fastening to be set on Binding post/stud 12, by the copper sheathing reinforced on insulating case 11, insulating case 11 can not be come off, also make Binding post/stud 12 leaky can not occur.
Further optimization such scheme, this insulating case 11 all has polytetrafluoroethylmaterial material to make with insulated column 14, and this polytetrafluoroethylmaterial material is produced by Suzhou Yan Nuo packaging material Co., Ltd, is prior art, too much do not repeat at this; The insulating case 11 made by polytetrafluoroethylmaterial material and insulated column 14 have good high temperature resistant, corrosion-resistant and can resist 1500 volts of high-tension characteristics; First sealing ring 15 and the second sealing ring 18 are made by hydrogenated nitrile-butadiene rubber, this hydrogenated nitrile-butadiene rubber is produced by the Dongguan power RunddichtringO of resistance to O Products Co., Ltd, there is splendid anticorrosive, tear-proof, high temperature resistant and not easily aging characteristic, sealing ring 15 should be made for prior art by hydrogenated nitrile-butadiene rubber, too much not repeat at this; Effectively can be ensured the sealing of terminal box by this first sealing ring 15 and the second sealing ring 18, prevent entering of air, ensure the vacuum degree of electric body 2 inside.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
