Abstract
The invention discloses a power cable switching device which comprises a plug, a socket, a socket insulting pedestal, a safe cover and a pressure spring. The socket is fixed in the socket insulating pedestal; one end of the plug is connected to a power cable in a crimping manner; the safe cover penetrates the end, connected to the power cable, of the plug, and covers the plug; the conical degree of the other end of the plug and the conical degree of a contact hole of the socket are both 1:50; the pressure spring is fixed at the inner side of the safe cover; and the pressure spring has a pre-stress when the safe cover is connected with the socket insulating pedestal. The power cable switching device has the advantages of being large in the current bearing area, high in the power cable switching reliability, high in vibration resistance, compact and reasonable in structure, long in service life, low in maintenance cost and safe and reliable.
Description
Technical field
What this technology related to is a kind of power cable switching device (being namely commonly called as: junction box).
Background technology
After the nineties in last century, along with the development of power consumption equipment, power line safety problem is outstanding day by day, the switching of power line is because loosening, by water or protect improper, constantly accidents caused, the electric power accident of about 80% is about had to be caused by cable loose contact according to data introduction, the mode of connection of traditional line ball nose+stud also exists wiring and loosens tendency, therefore the problem of power line conversion is the hidden danger of electric power safety all the time.
Summary of the invention
The technical scheme that this technology will solve is to provide one compared with prior art, has the power cable switching device of self-locking and fail safe.For solving the problem, this technology adopts following scheme: this technology comprises plug, socket, socket insulator foot, safety guard, stage clip; Socket is fixed in socket insulator foot, and by connecting reliably bottom socket, can realize the parallel connection of many group sockets: one end of plug is connected with power cable by crimping mode, the contact hole of the other end and socket is with the tapering having 1: 50.During use, plug should be rotated 0 °-5 ° relative to socket: one end that safety guard is connected with power cable through plug, cover on plug, a stage clip is equipped with in its cover inner side, when safety guard and socket insulator foot are tightened, stage clip has prestressing force, and safety guard is threaded with socket insulator foot is the most handy: when socket insulator foot is static, fixing occasion, rubber dust-proof safety guard used instead by safety guard.
Owing to adopting technique scheme, a kind of power cable switching device that this technology provides has following beneficial effect, namely large by flow area, power line switching reliability is high and have advantage, its compact conformation that shock resistance is good, safe and reliable, rationally, long service life, maintenance cost are low.
Accompanying drawing explanation
Fig. 1 is this technical pattern schematic diagram: 1, plug; 2, socket; 3, socket insulator foot; 4, safety guard; 5, stage clip.
Specific embodiment
Below in conjunction with accompanying drawing and embodiment, a kind of power cable switching device of this technology is further described.In Fig. 1, socket is 2, and socket insulator foot is 3, socket 2 is fixed in socket insulator foot 3, and plug is 1, and its one end is connected with power cable by the mode of crimping, the other end is the inserting column coordinated with socket 2, and the contact hole of socket 2 and the inserting column of plug 1 are with 1: 50 tapering had.Like this, when the inserting column of plug 1 and the contact hole of socket 2 form a pair Contact Pair, under the effect necessarily screwing power, the maximization by flow area can be realized, there is reliable self-locking property, and temperature rise is low, contact resistance is little.Safety guard 4, through plug 1 and power cable link, covers on plug 1, fills stage clip 5 inside safety guard; Safety guard 4 and socket insulator foot 3 are with being threaded, and now, the inserting column of plug 1 reliably inserts socket 2 contact hole, and the stage clip 5 in safety guard 4 has prestressing force.This makes the contact-making surface of plug and socket be in pressured state all the time, and the security protection performance of power cable transmission is further ensured.In addition, safety guard 4 and the cooperation place of socket insulator foot 3, can add sealing ring, and safety guard 4 can be coated with the line ball nose mating holes place of plug 1 and break marine glue, can realize water resistance more thoroughly like this.
Previous embodiment is only preferred embodiment of the present invention; should not be considered as restriction of the present invention; by all any personages being familiar with association area of the present invention; according to the technology contents disclosed by the present invention; can think easily and change or the modification of structure; or the equivalence change utilizing other structure or device to be realized, all should belong to and not depart from protection category of the present invention.
