Abstract
The utility model relates to an electric power stranded conductor connector.
The utility model discloses it has toper plug wire hole 2 to open on the metal wiring body 1, downthehole taper bolt 3 that has, and its rear portion has screw thread 4, cooperatees with screw 5 on the wiring body 1, and groove 6 is established to taper bolt 3's tail end face. The twisted wire can be tightly squeezed between the conical wire inserting hole 2 and the bolt 3 by screwing the bolt 3. Use the utility model discloses the stub that connects is firm reliable, contact resistance reduces greatly, and it is convenient to trade the line, is a better electric power connector.
Description
The utility model relates to a kind of electric power twisted wire electric wire connecting junction.
Chinese patent literature CN87206798 discloses a kind of " expansion-pressure type circuit electric wire connecting junction ".The metal connection device in a tubular form, twisted wire inserts the taper mouth of pipe, and the circular cone wedge is arranged in the pipe, the rearmounted gunpowder of wedge, the thrust that gunpowder explosion produces is inserted the circular cone wedge between the twisted wire, and twisted wire is firmly squeezed between the taper mouth of pipe and circular cone wedge, reaches good connection.But this programme also has following deficiency, the one, because the wedge expansive force is huge, connects and be permanent, and can't satisfy the needs that power line is changed; Two are to use gunpowder that many unsafe factors are arranged.
The purpose of this utility model is to provide a kind of gunpowder that do not use in order to overcome above-mentioned the deficiencies in the prior art, can make things convenient for the electric wire connecting junction of attaching.
The utility model is finished by following scheme.Have the taper plug wire hole on the metal connection body, taper bolt is arranged in the hole, the bolt front portion is a circular cone, and there is screw thread at the rear portion, matches with screw on the wiring body, establishes groove, hole so that turn at the bolt breech face.This taper bolt is free to advance or retreat, and thread-changing is convenient, and the expansive force after it is screwed into still can guarantee the twisted wire jam-packed is reached good contact.
Fig. 1 is a schematic diagram of the present utility model.
Now in conjunction with the accompanying drawings the utility model is further described.1 is the wiring body among the figure, which is provided with taper plug wire hole 2, establishes taper bolt 3 in the hole, and there is screw thread 4 at its rear portion, matches with screw 5 on the wiring body 1, and the breech face of taper bolt 3 is established groove 6 so that turn.During use, with the flush taper plug wire hole 2 of packing into of electric power twisted wire, firmly turn groove 6 with instruments such as screwdrivers, taper bolt 3 can be that the guide clamp-ons in the twisted wire and goes to bore point just, and the power that turns is big more, and bolt squeezes deeply more.When reaching as shown in Figure 1 projected depth, because the plug wire hole 2 on the wiring body 1 is tapered, so pressed the conical surface on the plug wire hole 2 by the twisted wire of tensioner and can not deviate from.When needing the transposing wiring, as long as the anti-bolt of twisting retreats it, twisted wire just can get loose.
For improving the expanding force of single taper bolt in plug wire hole 2 and tightening speed, the bus of bolt circle wimble fraction also can be designed to broken line, forms awl apical segment and awl figure.Usually, awl figure axial length is longer than the awl apical segment, and its tapering is also less than the awl apical segment.In the present embodiment, the ratio of two sections axial length is 1:4, and awl figure tapering is about 17 °, and the awl apical segment is about 73 °.
Experiment also shows, after the plug wire hole tapering is determined, the design of bolt awl figure tapering is preferably satisfied, the plug wire annulus area that hole and awl figure form on the basal cross section of plug wire hole hole can be slightly larger than hole and the annulus area of boring figure formation on the cross section, aperture, when guaranteeing the stressed complete tensioner in aperture, good contact is just arranged, to reach best effects at the bottom of the hole.The base ring area is bigger than choma area, can guarantee that tensioner is in the aperture, but big too much, then during the tensioner of aperture, still loosening at the bottom of the hole, obviously do not meet the wiring requirement; Can only say so is slightly larger than, and specific design can be determined by experiment according to different twisted wires, is not difficult.In this example, get 11 ° of 36 ' times when the plug wire hole tapering, the base ring area is bigger by 12.5% than choma area.
The end of a thread with the utility model attaching is solid and reliable, and contact resistance is little, and thread-changing is convenient, is a kind of electric wire connecting junction of power line preferably.
Claims (3)
1, a kind of expansion electric wire connecting junction has taper plug wire hole 2, and it is characterized in that has taper bolt 3 in the hole, and the breech face of taper bolt 3 is established groove 6, and its rear portion has screw thread 4 to match with screw 5 on the electric wire connecting junction 1.
2, expansion electric wire connecting junction as claimed in claim 1 is characterized in that the element of cone of described taper bolt 3 front portions is broken line, formed awl figure, and its axial length is longer than the awl apical segment, and its tapering is less than the sharp degree of awl.
3, expansion electric wire connecting junction as claimed in claim 2 is characterized in that after plug wire hole 2 taperings are determined, the annulus area that the hole becomes with the awl figure on the basal cross section of hole is slightly larger than the annulus area that the hole becomes with the awl figure on the cross section, aperture.
