Traditional cable fixing head mainly comprises the locknut that adapter body and the cable that is coated at adapter body penetrate end, wherein, adapter body offers the installation through hole that current supply cable passes, the cable traversing through end of adapter body has thread segment, and it is fixed on casing by the nut coordinated with thread segment; Locknut can be tightened in adapter body.During installation, first locknut is enclosed within cable, then makes cable penetrate the installation through hole of adapter body, and make locknut be tightened in adapter body, finally by hex nut, adapter body is fixed on casing, thus realize fixing cable.
But machinery equipment is normal with vibrations in running, cable fixing head can occur loosening because of the vibrations of machinery equipment in machinery equipment, causes the easier electric component from machinery equipment of cable to pull, there is the potential safety hazard of machinery equipment power-off, electric leakage.
In sum, how to improve the steadiness of cable fixing head in machinery equipment, with loosening of reducing that cable joint occurs in machinery equipment because of the vibrations of machinery equipment, thus the situation that minimizing cable pulls from the electric component of machinery equipment, reducing the potential safety hazard of machinery equipment power-off, electric leakage, is current those skilled in the art technical problems urgently to be resolved hurrily.
Utility model content
For above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of cable fixing head avoiding occurring above-mentioned technological deficiency.
In order to realize above-mentioned utility model object, the technical solution adopted in the utility model is as follows:
A kind of cable fixing head, comprises locknut 700, nut 500, thread bush main body 300, cable sealing ring 100 and the first sealing ring 40; Wherein:
In the inner chamber that described first sealing ring 40 is arranged on described thread bush main body 300 and its outer wall is close to the internal chamber wall of described thread bush main body 300;
The first end 302 of described thread bush main body 300 is provided with gear ring 301;
One end of described cable sealing ring 100 embeds in described gear ring 301, and described locknut 700 presses described cable sealing ring 100 and is assemblied on described first end 302;
Described nut 500 is arranged on the second end 303 of described thread bush main body 300, and the outer surface of described second end 303 is provided with screw thread, and described nut 500 is threaded with described second end 303.
Further, described first end 302 is set with packing ring 7.
Further, described thread bush main body 300 connects with cable sealing ring 100 to producing the first sealing ring 40 and extrudes, and makes the first sealing ring 40 produce inside projection 401.
Further, described second end 303 is set with the second sealing ring 600.
The cable fixing head that the utility model provides, mild to the inwall of the tubular installation portion of cable sealing ring by the inwall of thread bush main body, the i.e. plug-in mounting channels open of cable, cable can be avoided too to pull cable sealing ring because passage is narrow, prevent cable sealing ring from coming off, and then guarantee the reliability that cable sealing ring and thread bush main body are assembled, damage can not be produced to cable because of exterior vibration, guarantee cable security, clamping can be formed to cable outer rim, reach sealing effectiveness, the steel wire of cable can clamping fastener on cable fixing head, the needs of practical application can be met well.
