Description
Technical field
The present invention relates to the Waterproof connector of cable of cable gland, specially locking.
Background technology
Waterproof connector of cable, also known as cable gland, it is widely used in the terminal box of all kinds of motors, for fastening electric wire
Cable, tension, the anti-twisting property of electric wire are improved, play a part of protecting cable, and there is certain sealing effectiveness, can
Connection box for motor is set to reach certain degree of protection.Current existing water joint includes the inner cylinder 1 being through in terminal box, described
Annular ridge is provided with the middle part of the outer wall of inner cylinder 1, the fin is machined with external screw thread towards the outer wall on the outside of terminal box, twisted on external screw thread
There is locking nut 2, the inwall of inner cylinder 1 is machined with step hole towards terminal box lateral ends, sealing ring 3 is cased with shoulder hole,
The internal diameter of sealing ring 3, the internal diameter of locking nut 2, the internal diameter of inner cylinder 1 towards terminal box inner opposite end it is equal and with the diameter of cable 4
It is adapted.Cable is passed through by inner cylinder center, and locking nut internal diameter, internal diameter of the seal ring and inner cylinder are towards terminal box inner opposite end
Internal diameter is equal and is adapted with cable size, ensures that cable is formed with three respectively after passing through and seals, cable is fixed on and connect
In line box, it is allowed to that axial float does not occur.The structure can play for most of middle and small motor and protect cable well
Effect, but for the larger large and middle size motor of some terminal boxes, it is undesirable applied to the effect of the motor of vibration environment.It is existing
Water joint has the disadvantages that：1st, the cable of side outside connection box for motor, the cable of junction box side are only secured
Can not effectively it fix；2nd, there is wedge angle in the position of cable through water joint, and cable is easily hurt under vibration environment.Therefore,
Design is a kind of to be applied under vibration environment, can effectively fix large and middle size motor cable, and the waterproof for being not easy to hurt cable connects
Head is extremely necessary.
The content of the invention
The present invention solves current existing Waterproof connector of cable and is not suitable for vibration environment, can only link box outside one
The cable at end, and the problem of easy incised wound cable, there is provided a kind of Waterproof connector of cable of locking.
The present invention is achieved by the following technical solutions：It is provided with the middle part of the Waterproof connector of cable of locking, including outer wall
The inner cylinder of annular ridge, external screw thread is machined with respectively on the outer wall of fin both sides, be cased with horn mouth lock on the external screw thread of both sides respectively
Tight nut, one end internal diameter of the horn mouth locking nut towards inner cylinder are machined with step hole, the step hole
The internal thread coordinated with external screw thread is inside machined with, the other end oral area of the horn mouth locking nut is provided with continuous circular arc transition shape
Into outwardly open bell mouth shape flange, the inner cylinder inwall is lined with sealing ring, and internal diameter and the horn mouth of the sealing ring are locked
The minimum diameter of tight nut is equal and diameter with cable is adapted.Inner cylinder both ends outer wall is machined with external screw thread, on external screw thread
Horn mouth locking nut is cased with respectively, can be docked the inside and outside cable of line box respectively and be played fixation, horn mouth locking nut mouth
Portion is the outwardly open bell mouth shape flange that continuous circular arc transition is formed, and inner cylinder inwall is lined with sealing ring, and sealing ring is interior
Footpath is equal with the minimum diameter of horn mouth locking nut and diameter with cable is adapted, it is ensured that cable passes through under vibration environment
The inlet and an outlet portion of water joint will not occur to hurt the situation of cable, the internal diameter in step hole is loudspeaker without wedge angle fin
The minimum diameter of mouth locking nut is equal with internal diameter of the seal ring, serves position-limiting action to sealing ring, prevents under vibration environment
Axial float occurs for sealing ring, avoids that poorly sealed leakage accident occurs.
The present invention has advantages below：1st, slightly improved on the basis of existing water joint, you can existing to utilize
Water joint inner cylinder, has saved production cost；2nd, dock the inside and outside cable of line box and play fixation；3rd, bell mouth shape is convex
Edge can effectively prevent the cable of medium-and-large-sized motor under vibration environment from being hurt in water joint oral area.

Fig. 2 is structure half sectional view of the present invention；
In figure：1- inner cylinders, 2- locking nuts, 3- sealing rings, 4- cables, 5- horn mouth locking nuts.
Embodiment
The inner cylinder 1 of annular ridge is provided with the middle part of the Waterproof connector of cable of locking, including outer wall, is divided on the outer wall of fin both sides
External screw thread is not machined with, is cased with horn mouth locking nut 5, the direction of horn mouth locking nut 5 on the external screw thread of both sides respectively
One end internal diameter of inner cylinder 1 is machined with step hole, and the internal thread coordinated with external screw thread is machined with the step hole,
The other end oral area of the horn mouth locking nut 5 is provided with the outwardly open bell mouth shape flange that continuous circular arc transition is formed,
The inwall of inner cylinder 1 is lined with sealing ring 3, the internal diameter of the sealing ring 3 it is equal with the minimum diameter of horn mouth locking nut 5 and with
The diameter of cable 4 is adapted.
When it is implemented, the outer wall of horn mouth locking nut 5 is provided with the fin that outer rim encloses regular hexagon.Horn mouth is locked
Tight nut outer wall is provided with regular hexagon fin, is easy to use spanner locking horn mouth locking nut so that operation is more convenient, lock
It is tight more reliable.
