Abstract
The utility model relates to an anti-jamming shielded cable for a mining variable-frequency governor, which comprises a cable core wire, an outer insulation layer, a shielding layer and an inner insulation layer; and two ends of a cable of which the outer insulation layer, the shielding layer and the inner insulation layer are peeled off are crimped and sleeved with a copper wiring terminal, a first layer of heat shrinkable tube and a second layer of heat shrinkable tube in sequence. The utility model has the benefits that firstly, the anti-jamming performance for electromagnetic harmonic wave is superior to that of the cable in the traditional rejoining method; secondly, the measured electromagnetic disturbance value is lower than the electromagnetic disturbance value in the national GB12668.3 standard for the provisions of Articles 5 and 6 according to the electromagnetic compatibility EMC inspection performed via Shanghai Coal Academy Inspection Center; and thirdly, the temperature rise of a three-point crimping cable terminal is lower than that of the conventional crimping cable terminal.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of anti-interference shielded type cable that is used for mining variable-frequency governor.
Background technology
Be used for the effectively electromagnetism harmonic wave of the direct conduction of filtering of big-power transducer cable of the prior art and lead at present, pollute electrical network, disturb other electronic equipments.The cable junction easily produces local overheating in big current signal transmittance process in addition, and local temperature rise is too high, directly influences the electronic component operating characteristic, causes electric fault.
The utility model content
The utility model is to overcome above-mentioned weak point, purpose is to provide a kind of anti-interference shielded type cable that is used for mining variable-frequency governor, two layers of sleeve pipe outside original cable, have been added, and carry out 3 crimping, the electromagnetism harmonic wave that effective filtering is directly conducted, reduce the temperature rise of cable socket, solved problems of the prior art.
The utility model is to achieve the above object by the following technical programs: a kind of anti-interference shielded type cable that is used for mining variable-frequency governor, comprise cable core, external insulation layer, screen, inner insulating layer, copper binding post, ground floor heat-shrink tube, second layer heat-shrink tube on the pressure welding case of the two ends of the cable core of peeling off external insulation layer, screen, inner insulating layer successively.
As preferably, be welded with the ground connection termination that yellowish green lead the end of a thread connects at screen one end of peeling off external insulation layer.
As preferably, copper binding post is a silver-plated binding post after the surface finish.
The beneficial effects of the utility model: 1. anti-electromagnetism Harmonic Interference performance is better than traditional connection cable; 2. carry out electromagnetic compatibility EMC through inspection center of Shanghai coal science institute and detect, actual measurement electromagnetic disturbance value is lower than the electromagnetic disturbance value of 5～6 regulations in the national GB12668.3 standard; 3. 3 crimping cable termination temperature rises are lower than the cable socket temperature rise of conventional crimping.
