Description
Technical field
The utility model belongs to frequency converter waterproof connector technical field, more particularly, to a kind of inlet-outlet line of pump variable frequency device
Connector.
Background technique
When pump variable frequency device is connect with cable, usually on the shell of frequency converter setting disengaging wire terminal, cable pass through into
It is electrically connected after the sealing shroud of outlet joint with the electrical part in frequency converter, prevents water or moisture from cable and frequency converter shell with this
Junction disengaging frequency converter inside, and prevent junction cable from loosening, cable after loosening avoided to pull and fall from electrical part.But
It is the existing disengaging leakproofness of wire terminal and all inadequate to the fixing intensity of cable, sealing shroud is after tightening squeezes or becomes
Shape, then after some time of use, leakproofness can fail, cable can loosen.Therefore, it is necessary to be improved.
Summary of the invention
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of disengaging of pump variable frequency device
Wire terminal, it has the characteristics that good airproof performance, high to the fixing intensity of cable.
To achieve the goals above, the technical scheme adopted by the utility model is a kind of inlet-outlet line of pump variable frequency device
Connector, including inlet-outlet line screwed pipe, sealing ring and nut, are fixed with hexagonal shim in the middle part of the inlet-outlet line screwed pipe, and six
Hex nut is bolted on inlet-outlet line screwed pipe on the right side of the shim of angle, the sealing ring includes half circle body A and half circle body B,
The both ends of the half circle body A are provided with connection tenon, and the both ends of the half circle body B are provided with and the company that connect tenon cooperation
Joggle slot；The inner sidewall of the sealing ring is provided with several annular protruding ribs；
The left end of inlet-outlet line screwed pipe is provided with tightening grid circle, is provided with sealing on the inside of the left end of the inlet-outlet line screwed pipe
Seat；
The left end of nut is provided with tightening cap, tightens and is provided with entrance hole at the axis of cap, and the aperture of entrance hole is by left-hand
It is right linear to increase, and with the screw hole of nut is isometrical is connected to；
The sealing ring is mounted in tightening grid circle, and is resisted against on the seal receptacle of inlet-outlet line screwed pipe, and nut is spirally connected
In the left end of inlet-outlet line screwed pipe.
The right end of the inlet-outlet line screwed pipe is additionally provided with seal washer.
After adopting the above structure, the utility model is compared to the prior art advantageously: the utility model it is close
Seal is mutually connected using half circle body A and half circle body B by connection tenon and connection tongue-and-groove, and setting on the inside of sealing ring
There is annular protruding rib, can effectively improve its leakproofness between cable and is connected and fixed intensity.
Detailed description of the invention
Fig. 1 is the structural schematic diagram (main view) of the utility model.
Fig. 2 is the main view of the utility model sealing ring.
Fig. 3 is the right view of the utility model sealing ring.
Specific embodiment
As described below is only the preferred embodiment of the utility model, does not therefore limit the protection model of the utility model
It encloses, the present invention will be further described with reference to the accompanying drawings and examples.
Embodiment, as shown in Fig. 1 to Fig. 3: a kind of disengaging wire terminal of pump variable frequency device, including it is inlet-outlet line screwed pipe 1, close
