Background technology:
The cable leading-out end is a kind of connector, is mainly used in traction and fixing cable or tubular object.This kind connector uses widely in various device and field.The cable leading-out end generally is applied in the goods such as mechanical control cabinet, affairs instrument, distribution board or electrical equipment, so that its cable is fixed, avoids it to cause impaired because of slippage or rotation accident.Also cable is installed on the connection box for motor by the cable leading-out end.Because the operational environment of motor, particularly outdoor motor will prevent that therefore, the sealing of connection box for motor cable leading-out end is very important because of destroying the motor operate as normal in humidity, dust deposit or the worm ant access arrangement system.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, and waterproof, the connection box for motor cable that moisture effect is good are drawn and used seal nipple.
The utility model is achieved in that
The connection box for motor cable is drawn and is used seal nipple, include: joint body: joint body is the tubular of hollow, the middle part arranged outside of joint body has many ribs fixed part, both sides at fixed part are provided with external screw thread, wherein the externally threaded end axis of a side is to outwards being arranged at intervals with several outer surfaces clamp jaw of inside undergauge gradually, be provided with sealing plug in the clamp jaw, clamp jaw is bolted with the clamping nut that compresses clamp jaw and sealing plug outward.
Above-mentioned sealing plug is a hollow frustum, is to make with elastomeric material.
The big end of diameter of the hollow frustum of above-mentioned sealing plug is the thin-walled blind end.
The afterbody inner surface of above-mentioned clamping nut is the diminishing annular surface of diameter, the head inner surface is provided with joint body on have the external screw thread of clamp jaw one side to cooperate the internal thread that is spirally connected.
The inner surface of above-mentioned joint body has the externally threaded end of clamp jaw one side inner surface to be provided with annular boss, and the end of the sealing plug of the big end of diameter is stuck on the annular boss.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model includes body, sealing plug and forcing piece, and is simple and reasonable for structure, and it is convenient to realize;
2, the utility model adopts between sealing plug and the body and seals, forcing piece forces clamping jaw to be dwindled, and clamp jaw forces sealing plug to dwindle with cable and combines closely good airproof performance, moisture effect is good, can also prevent dust, prevent to destroy function in the worm ant access arrangement system;
3, the utility model is applied in the goods such as mechanical control cabinet, affairs instrument, distribution board or electrical equipment, in order to cable is fixed, moistureproof.

Embodiment:
With specific embodiment the utility model is further described below, referring to Fig. 1-5:
The connection box for motor cable is drawn and is used seal nipple, include: joint body 10: joint body 10 is the tubular of hollow, the middle part arranged outside of joint body 10 has many ribs fixed part 102, be provided with external screw thread 101,103 in the both sides of fixed part 102, wherein the end axis of a side external screw thread 103 is to outwards being arranged at intervals with several outer surfaces clamp jaw 104 of inside undergauge gradually, be provided with sealing plug 20 in the clamp jaw 104, the clamp jaw 104 outer clamping nuts 30 that compress clamp jaw 104 and sealing plug 20 that are bolted with.
Above-mentioned sealing 20 plugs are a hollow frustum, are to make with elastomeric material.
The big end of diameter of the hollow frustum of above-mentioned sealing plug 20 is the thin-walled blind end.
Afterbody 302 inner surfaces of above-mentioned clamping nut 30 are the diminishing annular surface of diameter, the head inner surface is provided with joint body on have the external screw thread 103 of clamp jaw 104 1 sides to cooperate the internal thread 301 that is spirally connected.
The inner surface of above-mentioned joint body 10 has the end inner surface of clamp jaw 104 1 side external screw threads 103 to be provided with annular boss 105, and the end of the sealing plug 20 of the big end of diameter is stuck on the annular boss 105.
Clamp jaw 104 is provided with at interval, is provided with the gap between clamp jaw 104, like this can be by clamping nut 30 with its locking.
Occupation mode of the present utility model:
The utility model is not when installing cable, the external screw thread and the connection box for motor of joint body 10 1 ends are spirally connected, the big end of the diameter of sealing plug 20 is stuck on the annular boss 105, the external screw thread 103 and clamping nut 30 internal threads 301 of clamp jaw 104 1 sides of joint body 10 screw, because an end of sealing plug 20 at this moment, can reach the effect of sealing, protection against the tide, waterproof and dustproof, insect protected ant for what seal, guaranteed that motor in transportation or storing process, does not damage because of external environment;
When cable 40 is installed, the big end of the diameter of sealing plug 20 is stuck on the annular boss 105, the big end of the diameter of sealing plug 20 is the thin-walled blind end, there is the end inner surface of clamp jaw 104 1 side external screw threads 103 to be provided with annular boss 105 sealings with the inner surface of joint body 10, the thin-walled blind end that cable 40 is worn out sealing plug 20 passes joint body 10, clamping nut 30 passes the other end of cable 40, be spirally connected with the external screw thread 103 of clamp jaw 104 1 sides of joint body 10, screw clamping nut 30, force clamp jaw 104 to dwindle, clamp jaw 104 forces sealing plug 20 to dwindle with cable 40 and combines closely, at this moment, just reach sealing, moistureproof, waterproof, dustproof, the effect of insect protected ant has guaranteed that motor does not in use destroy the motor operate as normal because of extraneous factor.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection range of the present utility model.
