Description

Twist pressure type electric wire connector

[technical field]

The utility model relate to the electric wire joint jockey, spiral fluted cover or circle are arranged, refer to a kind of stubborn pressure type electric wire connector especially.

[background technology]

Referring to Fig. 1-Fig. 6; The high-voltage cable connector of prior art comprises sleeve pipe 1 and screw 2 ' (or 2 "); respectively there are two screws 12 the A-A both sides, horizontal middle section at sleeve pipe 1; said screw 2 ' (or some roads groove 21 ' (or 21 ") are arranged on 2 "), screw 2 ' (or 2 ") and screw 12 link the cable joint at threading 1 two ends twisted to compress and be fixed in the sleeve pipe 1, in stubborn pressure process; Screw 2 ' (or 2 ") receive torsion to locate fracture along groove 21 ' (or 21 "), and the outsourcing isolating shrinkable tube is accomplished the connection of two cables (electric wire) then.But the outer-hexagonal screw 2 as shown in Figure 3 of the high-voltage cable connector of prior art institute adapted ' fracture position imprecise; When cable size is big, have and make broken end protrude in the possibility outside the sleeve pipe 1; Make connector add the bag isolating shrinkable tube after air spots, the portion of exposing can produce the high voltage arc phenomenon; Shown in Figure 5 vertically have draw-in groove 22 " screw 2 " then also can produce the high voltage arc phenomenon because of draw-in groove has the slit, and both of these case all may produce air and blow isolating shrinkable tube, and this is its shortcoming.

[summary of the invention]

Shortcoming to prior art; The purpose of the utility model is to provide a kind of can guarantee that the broken end of said screw can not protrude in outside the sleeve pipe; Connector adds surfacing behind the bag isolating shrinkable tube, can not produce high voltage arc and can not produce the stubborn pressure type electric wire connector that air is blown the isolating shrinkable tube phenomenon thereby there is the draw-in groove slit simultaneously.

The utility model solves the technical scheme that its technical problem adopted: a kind of stubborn pressure type electric wire connector; Comprise sleeve pipe and screw; Respectively there are two screws both sides, horizontal middle section at sleeve pipe, and some roads groove is arranged on the said screw, and screw can be screwed in the screw and link with screw; It is characterized in that: the head of screw of said screw is cylindrical, prismatic endoporus is arranged between wherein; And include box spanner; Said box spanner comprises sleeve, socket cover and prismatic spanner; Prismatic spanner is fixed in the middle of the sleeve; The lower surface of this prismatic spanner is concordant with the lower surface of sleeve, and matches and turn screw with prismatic endoporus in the screw, and sleeve is inserted in the screw rotationally.

Said socket cover and sleeve can be integral structure or split built-in structure, and the fixing of said prismatic spanner and sleeve can be welding or bonding.For socket cover is combined firmly with prismatic spanner, can there be a holding screw to pass sleeve wall and socket cover with prismatic spanner tightening.

Prismatic endoporus in the said head of screw can be triangular prism, quadrangular, pentagonal prism or six prisms; Correspondingly said prismatic spanner is triangular prism, quadrangular, pentagonal prism or six prismatic spanners.

After handling well, the termination of two cables (electric wire) that will connect during use inserts from the sleeve two ends respectively; The screw of screwing on; Then prismatic spanner is inserted the prismatic endoporus of screw head, tighten screw, because the maximum of the suffered torsion of screw is at the place, lower surface of prismatic spanner; Thereby when screw with cable (electric wire) if continue to strengthen torsion after compressing, screw will be at the place, lower surface of prismatic spanner or one groove fracture below the lower surface.The broken end of screw just can not protrude in outside the sleeve pipe like this, and connector adds surfacing behind the bag isolating shrinkable tube, simultaneously owing to there is not draw-in groove slit longitudinally, can not produce air and blows the isolating shrinkable tube phenomenon thereby can not produce high voltage arc.

The beneficial effect of the utility model is: the broken end that can guarantee said screw can not protrude in outside the sleeve pipe; Connector adds surfacing behind the bag isolating shrinkable tube, can not produce high voltage arc and can not produce the stubborn pressure type electric wire connector that air is blown the isolating shrinkable tube phenomenon thereby there is the draw-in groove slit simultaneously.
