Abstract
The utility model discloses a two phase three channel multi-purpose hermetic plug mainly used for the installation of the motive power of the electric engineering and the equipment. Under the condition of non broken line or line dividing, the cable is sealed and insulated. The utility model is composed of a power line box body and two two-phase electric plugs. The bottom parts of the plugs adopts with cable clips, increasing the tensile strength of the cable, avoiding generating the broken circuit and the short circuit. The inner parts of the plugs adopt the connection of two phase three channel, and adopt the method of the ground electrode firstly connecting with the earth, improving the safety factor. The utility model is suitable for using in the moist environment or exposing in the atmosphere for long term, can be used for the industrial power distribution, and can be used for the power transmission.
Description
The utility model relates to a kind of electric middle separated time plug that uses, and belongs to the electric device class.
In electrical engineering and equipment dynamic are installed, meet the problem of separated time and broken line on occasion, all be broken line in main line earlier according in the past convention, wiring then, finally with the insulating tape wrapping to play an insulating effect.Can not guarantee safety like this.Owing to expose in atmospheric environment for a long time, insulating tape is constantly aging, corrosion, thereby electric leakage, jeopardizes personal safety.In addition, wrap up lead with insulating tape in the environment at the scene, tensile strength is extremely low, forms easily and opens circuit and short circuit, causes electric equipment to work and to damage, and influences normal production work.
The purpose of this utility model is to provide a kind of two phase electricity multipurpose threeway sealing separated time plug, and this separated time plug is convenient and reliable, good seal performance, and adaptability is strong and have an advantages of higher tensile strength.
Multipurpose threeway sealing plug of the present utility model is made up of box body and two two phase electricity plugs.The coverboard that the shell of box body is made by insulating material such as poly-tetrafluoro and nylon 66 is assembled, is fixed together with sealed screw and round section joint ring.Two ends, the box body left and right sides are equipped with power-line plug and fixed mount respectively.Power-line plug is made of insulation shell, seal cover, trapezoidal sealing ring and cable clip.Fixed mount adopts " U " shape slot type bayonet socket to add screw and forces fixing form.The pipe electrode that the inside of box body has three brass materials to make, and three binding posts are arranged.
The outside of two two phase electricity plugs is made up of the stator of insulation shell, trapezoidal sealing ring, seal cover, cable clip, lock ring, phenolic resin material system and fixed screw etc.Three bar electrodes and three binding posts that the inside of plug is made by brass material constitute.The connected mode of two phase electricity plug and box body is a plug-in type, and is tight with lock ring after inserting.The exposed parts of whole two phase electricity multipurpose threeway sealing separated time plug all adopts insulating material to make.
Two phase electricity multipurpose threeway sealing separated time plug of the present utility model compared with prior art has following advantage:
1, under the situation of not having broken line or separated time, cable is sealed, guaranteed good insulation performance, therefore applicable to exposing for a long time in atmosphere or in a humid environment.
2, cable clip is adopted in the bottom of this plug, has increased the tensile strength of cable, avoids opening circuit and short circuit.
3, this plug inside adopts the two-phase three-wire system connection, and adopts the way of grounding electrode elder generation ground connection, makes at first ground connection of electric leakage equipment, has improved safety factor, has guaranteed personal safety.
The embodiment that provides below in conjunction with accompanying drawing 1 is further described the utility model.
Accompanying drawing 1 is the structure chart of two phase electricity multipurpose threeway sealing separated time plug.
Two phase electricity multipurpose threeway sealing separated time plug among the embodiment is made of box case (1), pipe electrode binding post (2), pipe electrode (3), lock ring (4), plug body (5), seal cover (6), cable clip (7), sealed screw (8), fixed mount (9), " O " shape sealing ring (10), bar electrode seat (11), bar electrode (12), bar electrode binding post (13), trapezoidal sealing ring (14), plug fixed screw parts such as (15).
This plug adopts the two-phase three-wire system connection, can use the electric equipment of electric current 15A, and maximum current can use 20A.Contact resistance very little (＜0.001OHM).During use, at first must under the situation of outage, plug be plugged,, cause short circuit and open circuit with unburned ring electrode.Its using method is as follows:
(1) at first the close screw of envelope (8) of box body (1) is opened, then feed cable is passed cable clip (7), seal cover (6), trapezoidal sealing ring (14), inject in the box body (1), on power line access tube electrode connection terminal (2), ground wire inserts on the extra heavy pipe electrode.
(2) the sealing baffle lid with box body (1) is tight then, tightens sealed screw (8), more trapezoidal sealing ring (14) is put into box body (1), tightens seal cover (6), tightens cable clip (7), and power line is not had till the twitch.
(3) open plug (5) fixed screw (15), the line that connects passes cable clip (7), trapezoidal sealing ring (14), seal cover (6), insert on the binding post (13) of three bar electrodes of plug (12), then with plug (5) fixedly spiral shell (15) tighten, put trapezoidal sealing ring (14) in plug (5) bottom, tighten seal cover (6), tighten cable clip (7), lead is not had till the twitch.
(4) plug (5) is inserted box body (1), tightens lock ring (4) by thick, thin electrode, so just finished all the use operations of this plug.
Two phase electricity multipurpose threeway sealing separated time plug is applicable to field, explosion-proof occasion, carries out wiring under the situation of not having broken line.This plug is not suitable for the transmission engineering of portable electric power, as: and tie, separated time in parallel etc. and industrial power distribution and electric power transfer, as factory, machine room, dwelling house, power plant etc.
Claims (4)
1, the two phase electricity multipurpose threeway sealing separated time plug that uses during a kind of electrical engineering and equipment dynamic are installed, comprise power supply wiring part and separated time part, it is characterized in that: power supply wiring partly is a box body, separated time partly is two two phase electricity plugs, and bar electrode and bar electrode binding post and pipe electrode and pipe electrode binding post that optimum electric conducting material is made are housed respectively in box body and the plug.
