Specific implementation mode
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
Referring to Fig. 1, the cable entry in the present embodiment, cable is introduced electrical equipment, including to examine
Survey cable connector humidity the first Humidity Detection part 1, to the humidity of cable connector be more than the first default humidity value when give
Cable connector carries out the first air-heater 2 of air blast, the humidity of humidity detector detection cable connector to be less than or equal to
Leading-in terminal 3, the cable to introduce leading-in terminal 3 of the cable introducing of default humidity value compress, cable are introduced to electricity
The compression terminal 5 of device equipment be connected to through-hole 4, detecting compression terminal 5 to be connected to leading-in terminal 3 with compress terminal 5
Second Humidity Detection part 6 of humidity and to compress terminal 5 humidity be more than the second default humidity value when to compress terminal 5 into
Second air-heater 7 of row air blast.
Herein, the humidity of 1 detection cable connector of the first Humidity Detection part, when the humidity of cable connector is more than first default wet
Air blast is carried out to cable connector by the first air-heater 2 when angle value so that the humidity of cable connector is the first default humidity value, is kept away
Exempt from the excessively high damage cable of cable humidity, cable is introduced through connection through-hole 4 to terminal 5 is compressed, compresses terminal 5 by leading-in terminal 3
Cable is compressed, cable is then introduced to electrical equipment, the detection of the second Humidity Detection part 6 compresses the humidity of terminal 5, works as compression
Air blast is carried out to terminal 5 is compressed by the second air-heater 7 when the humidity of terminal 5 is more than the second default humidity value so that from compression
The cable humidity that terminal 5 is drawn is the second default humidity value, ensures the drying for entering the cable in electrical equipment, improves cable
Usability, simple in structure, efficiency is higher.
First Humidity Detection part 1 and the second Humidity Detection part 6 can be humidity sensor.Humidity sensor can pass through survey
After measuring humidity, it is transformed into electric signal or the information output of other required forms according to certain rules.Humidity sensor can be
Lithium chloride humidity sensor, carbon dew cell, aluminium oxide hygrometer or Ceramic Humidity Sensor.
It can be clamp nut to compress terminal 5, can thus be clamped cable.Retainer plate can be equipped on clamp nut
81, the compression strip 82 to clamping cables can be equipped on retainer plate 81.Retainer plate 81 can be bolted on compression end
On son 5.Compression strip 82 can be fixed on by the cooperation of screw bolt and nut on retainer plate 81.Compression strip 82 can be two difference
It is set to and compresses 5 both ends of terminal, be equipped among compression strip 82 to be matched for clamping tightly the concave arc of cable.
4 inside of connection through-hole can be equipped with to seal the sealing element 41 of connection through-hole 4, in this way it is prevented that extraneous ring
Border influences cable, and cable is avoided to moisturize.Sealing element 41 can be elastic seal ring, according to the diameter sealing ring of cable
Diameter can also change, the cable extrusion sealing ring when cable size is larger, and when cable size is smaller, sealing ring abuts cable.
Can also the pressure ring to squeeze sealing member 41 be set in sealing ring and outer surface so that sealing element 41 abuts cable, and pressure ring can
To be close to the setting of sealing element 41.
First default humidity value and the second default humidity value can be equal, can thus so that the humidity of cable is default
Humidity value ensures that cable uses under dry environment, avoids cable from moisturizing and influences the quality of cable.
Cable connector can be equipped with cable to be dragged to the dragging part for compressing terminal 5 from leading-in terminal 3, thus may be used
From 5 side of terminal pulling cable is compressed to terminal 5 is compressed, to avoid pushing cable to enter compression terminal 5 from 3 side of leading-in terminal
Inconvenient user uses.Dragging part can be dismantled when cable is dragged completion from cable.
Dragging part may include being connected to the snap ring 91 of cable connector end and being arranged at 91 center of snap ring, to dynamic
The connecting rod 92 of cable is driven under the driving of power, thus can drive electricity by pulling connecting rod 92 that snap ring 91 is driven to move
Cable moves in leading-in terminal 3.
Snap ring 91 can be the annulus for the diameter that diameter is less than cable, in this way it is prevented that when 91 diameter of snap ring is excessive,
Drive cable movement in connection through-hole 4 that can damage sealing element 41 in dragging part.
Cable entry as the present embodiment can also include the stepper motor 93 for driving dragging part, thus
It can drive dragging part that cable is driven at the uniform velocity to move by stepper motor 93.
Herein, stepper motor 93 can be a kind of induction machine, and direct current is become time sharing power supply by it by electronic circuit,
Multinomial timing control electric current, in the case of non-overload, the rotating speed of motor, the position of stopping are solely dependent upon the frequency of pulse signal
And umber of pulse, without being influenced by load variation, as soon as when step actuator receives a pulse signal, its Driving Stepping Motor
93 by setting directions rotate a fixed angle, referred to as " step angle ", its rotation be with fixed angle step by step
Operation, angular displacement can be controlled by controlling pulse number, to achieve the purpose that accurate positionin；It can pass through simultaneously
Pulse frequency is controlled to control the speed and acceleration of motor rotation, to achieve the purpose that debugging.Stepper motor 93 can be
Reaction stepping motor 93, p-m step motor 93, composite stepper motor 93, single-phase stepper motor 93 or plane stepping electricity
Machine 93.
Specific embodiment described herein is only an example for the spirit of the invention.Technology belonging to the present invention is led
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
