Abstract
The utility model discloses an improved three-phase four-line power source socket, the upper part and lower part of the wall of the hole of the socket are respectively provided with a transverse groove (3), and a steel wire spring ring (4) is arranged in the groove (3), when a plug is inserted into the socket hole, the plug and the socket hole fit properly due to the fastening function of the two steel wire spring rings, the surface contact between the plug and the socket hole forms a big section through which the current flows, and heat generation does not happen; and since the fit is proper and the insertion and pull of the plug is easy, the plug does not be cracked and broken when pulled, danger and waste do not occur.
Description
The utility model relates to a kind of improvement of electric outlet structure.
At port and pier, all kinds of operation boats and ships are gone out operation when returning pontoon bridge and stopping, and generally connect the bank electricity, are connected the electric supply power mode electricity consumption of employing bank by the cable plug on the ship with socket in the shore connection box.The present socket that uses, with process that plug is connected in exist below some problems and shortcomings: because plug and the socket aperture angle is irregular and fit clearance is improper, be to contact between plug and the socket aperture, the cross section that the formation electric current is flowed through is little, cause heating, and cause socket plug to burn out; Because plug and the socket aperture angle is irregular and fit clearance is improper, cause the plug difficulty, usually plug is pulled out and split, pull out broken, produce dangerous, cause waste, before the utility model design is finished, not seeing the improved three-phase four-wire power socket identical with the utility model structure as yet uses in people's routine work, not seeing the improved three-phase four-wire power socket identical with the utility model structure has sale on market, it is on the books in the literature also not see the improved three-phase four-wire power socket identical with the utility model structure.
The purpose of this utility model is to provide a kind of improved three-phase four-wire power socket, realizes that plug cooperates with socket aperture suitably, is that face contacts between plug and the socket aperture, and the cross section that the formation electric current is flowed through is big, can not cause heating; And owing to cooperate suitably, plug can not pulled out plug and split easily, pulls out brokenly, produces dangerously, causes waste.
For achieving the above object, the utility model adopts following technical proposals:
A kind of improved three-phase four-wire power socket, form by housing, wiring cylinder and three the wiring cylinders that have socket aperture that have socket aperture, the wiring cylinder comprises socket hole wall and the wiring hole wall that links together, socket hole wall in the vertical direction has two slits of symmetry, form two socket aperture sheets, it is characterized in that a horizontal groove respectively being arranged, in groove, place the wire spring circle in the upper and lower of socket hole wall.
In such scheme, can on said two socket aperture sheets, weld a lead and connect.
The said lead of such scheme can be welded on the position of the socket aperture sheet between the two wire spring circles.
The said lead of such scheme can be made of copper.
The utility model has more following effects and good effect:
The utility model provides a kind of improved three-phase four-wire power socket, owing to a horizontal groove is respectively arranged in the upper and lower of socket aperture, in groove, place the wire spring circle, when with the plug insertion socket hole, being subjected to the fastening effect of two wire spring circles, realizing that plug cooperates with socket aperture suitably, is that face contacts between plug and the socket aperture, the cross section that the formation electric current is flowed through is big, can not cause heating; And owing to cooperate suitably, plug can not pulled out plug and split easily, pulls out brokenly, produces dangerously, causes waste.
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail:
Fig. 1 is structure (main looking) schematic diagram of the included wiring cylinder of the utility model;
Fig. 2 is structure (side-looking) schematic diagram of the included wiring cylinder of the utility model;
Fig. 3 is structure (overlooking) schematic diagram of the included wiring cylinder of the utility model;
Fig. 4 is the included socket aperture chip architecture schematic diagram of the utility model.
In the drawings,
The 1st, wiring cylinder, the 2nd, slit, the 3rd, groove, the 4th, wire spring circle, the 5th, socket aperture sheet, the 6th, lead, the 7th, solder joint, the 8th, socket aperture, the 9th, wiring hole screw hole, the 10th, wiring hole, the 11st, wiring hole wall, the 12nd, wiring cylinder fixing screw hole.
A kind of improved three-phase four-wire power socket, form by housing, wiring cylinder and three the wiring cylinders 1 that have socket aperture that have socket aperture, wiring cylinder 1 comprises socket hole wall and the wiring hole wall 11 that links together, socket hole wall in the vertical direction has two slits 2 of symmetry, form two socket aperture sheets 5, it is characterized in that a horizontal groove 3 respectively being arranged, in groove 3, place wire spring circle 4 in the upper and lower of socket hole wall.
In such scheme, can on said two socket aperture sheets 5, weld a lead 6 and connect.
The said lead 6 of such scheme can be welded on the position of the socket aperture sheet 5 between the two wire spring circles 4.
The said lead 6 of such scheme can be made of copper.
