Description

Three-phase and quadrupole sealed type cable plug, socket

The utility model relates to electric connector field, is meant three-phase and quadrupole sealed type cable plug, socket especially.

In background technology, the cable joint of being sold in the market, i.e. cable plug, socket, its capacity are more than 60 peaces, its structure is to assemble the insulation stem stem by screw on metal shell, and the structure that has also adopts thrust spring coil or insulating press boards to come fastening insulation stem stem.Its weak point: (1) adopts screw to connect because its product cavity volume is little, the hole wall in insulation stem stem screwing hole as thin as a wafer, so in use, plug inserts, extracts, product is easy to damage.(2) inconvenience, low precision are installed.What (3) have is drilled with screwing through hole on metal shell, cause product hermeticity bad, poor reliability.

The purpose of this utility model is to overcome weak point in the above-mentioned background technology, develop a kind of three-phase and quadrupole sealed type cable plug, socket, improve assembly precision and intensity, eliminate insulator damage, improve product hermeticity, enlarge the scope of application, improve combination properties such as security of products and reliability, avoid accident to take place.

Technical solution of the present utility model is as follows:

Comprise: with locking blind nut 7 assembling procapsids 13, assemble contact pin insulated column 10 in the procapsid 13 on the pedestal 5, it is characterized in that: assembling has the insulation stem stem 1 of chock 20 in the pedestal 5.

Technical solution of the present utility model also comprises:

Notched face-flange 22 is arranged in the pedestal 5, and assembling has the insulation stem stem 1 of plane chock 20 and plane outward flange 21 on the pedestal 5, and its plane chock 20 is corresponding with flange 22.

Notched inclined-plane flange 22 is arranged in the pedestal 5, and assembling has the insulation stem stem 1 of inclined-plane chock 20 and inclined-plane outward flange 21 on the pedestal 5, and its inclined-plane chock 20 is corresponding with flange 22.

Notched helicoid flange 22 is arranged in the pedestal 5, and assembling has the insulation stem stem 1 of helicoid chock 20 and helicoid outward flange 21 on the pedestal 5, and its helicoid chock 20 is corresponding with flange 22.

Assembling phase line, zero

2 and 3 in the insulation stem stem 1, on the jack post with locking spring 25, the fore-set 24 elastic top stressed joint cables 23 of hollow jackscrew 18 and Qi Nei.

Advantage of the present utility model and effect are as follows:

(1) owing to adopt chock and flange coupling mode,, improved the explosion-proof performance in using, improved fail safe and the reliability used so improved assembly precision and intensity.

(2) owing to adopt bind mode in chock and the flange, so there is not screw hole on the housing, in addition, the overall structure junction has sealing ring, pad, so improved the sealing of product, has enlarged the scope of application.

(3) because chock and flange coupling method so the cavity volume of product increases, have improved the insulation property of product, improve combination property and each top index, be applicable to various environment.

It is as follows that this reality acts on novel description of drawings: the straight seat of Fig. 1 formula plug, socket installation diagram, Fig. 2 is a left view among Fig. 1, Fig. 3 is an insulation stem stem schematic diagram, Fig. 4 is the metal shell schematic diagram, Fig. 5 is two wedge shapes insulation stem stem and metal shell assembling complete section schematic diagram, Fig. 6 is three wedge metal shell front views, Fig. 7 be among Fig. 6 A to view, Fig. 8 is the left view of Fig. 6, Fig. 9 is the B-B cut-away view of Fig. 8, and Figure 10 is three a wedge shapes insulation stem stem front view, and Figure 11 is the left view of Figure 10, Figure 12 be the B of Figure 10 to view, Figure 13 is that C amplifies the work cutaway view to the part among Fig. 2.Above-mentioned number in the figure is described as follows: the 1-stem stem that insulate, 2-phase line jack post, 3-zero line jack post, 4-short trouble indicator light, 5-pedestal, the 6-spring coil, 7-locks blind nut, 8-sealing gasket, 9-clamp-screw, 10-contact pin insulated column, 11-zero line contact pin, 12-phase line contact pin, 13-procapsid, the 14-gland, 1 5-cable gland, 16-cable clip, 17-cable clip screw, the 18-jackscrew, 19-screw, 20-chock, 21-outward flange, the 22-flange, 23-cable, 24-fore-set, the locking spring of 25-.

Be description of drawings of the present utility model below: referring to Fig. 1, assemble insulation stem stem 1 by chock and flange mode in the pedestal 5, insulation stem stem 1 internal fixation three a phase line jacks post 2 and a zero line jack post 3 (referring to Fig. 2), a short trouble indicator light 4 is arranged on the pedestal 5, but insulation stem stem 1 left end stube cable does not draw among the figure; Use screw 9 fixing plug pin insulated columns 10 in the procapsid 13, three phase line contact pins 12 of assembling and a zero line contact pin 11 on insulated column 10, with phase line, zero
