Abstract
The invention relates to a bidirectional spinning type electric joint, belonging to devices for realizing electric connection of two leads in a spiral press connection manner. A double-head inner sleeve is formed by integrating a left assembly and a right assembly, and the left assembly and the right assembly are symmetrical bilaterally and have the same structure. The left assembly consists of a cylinder and a variable-diameter shrink tube at the outer end of the left assembly, the cylinder of the left assembly is provided with outer thread, and the variable-diameter shrink tube is divided into 4-8 tongue sheets through axial notches. The device further comprises two same conical shells, each conical shell is internally provided with a through hole formed by articulating a cylindrical hole and a conical hole, and inner thread screwed with the outer thread of the double-head inner sleeve is arranged on the cylindrical hole. The bidirectional spinning type electric joint disclosed by the invention has the characteristics of large fastening gripping strength, small contact resistance and convenience for use.
Description
Technical field
The present invention relates to be used for the joint that two wires connect, the connector that particularly adopts spiral crimping mode that two conductor compression jointings are realized being electrically connected.
Background technology
In the electric power, cable connects metal and mainly contains device clamp and line nose.Device clamp need be tightened a plurality of nuts in use, makes troubles to on-site construction operations.The line nose need cooperate the dedicated hydraulic instrument to use, and to site operation, particularly rushes to repair the worker and makes troubles.
Summary of the invention
The purpose of this invention is to provide and a kind ofly adopt spiral crimping mode and the low two-way rotary extrusion type spinning electrical connector of contact resistance.
The objective of the invention is to realize like this: cover is by the identical left part of left-right symmetric, structure with right part is integrated constitutes in a kind of two-way rotary extrusion type spinning electrical connector, double end; This left side part is made up of the reducing shrink cylinder of a cylinder and outer end thereof, and cylinder that should left side part is provided with external screw thread, and this reducing shrink cylinder is divided into 4～8 tongue pieces through axial cut-outs; Two identical tapered jackets: have in it by cylindrical hole and round taper hole to be connected a through hole that forms, and have on the position of this cylindrical hole with double end in the internal thread that spins of the external screw thread that puts.
The cover middle part is provided with turret head in the above-mentioned double end.
The integrated turret head that is provided with on the above-mentioned tapered jacket.
Compared with prior art, the present invention has following characteristics:
1, screw thread crimping structure is installed simply, need not professional tool.
2, torque nut, constant pressure is guaranteed good being electrically connected and damage wires not.
3, terminal connects with the crimping mode, and it is low, moistureproof to have a contact resistance, waterproof, and the anticorrosion advantage prolongs useful life of insulated conductor and joint.
4, be applicable to the connection of two leads (like copper, aluminium material) of unlike material.
5, contact resistance is little, and contact resistance meets the DL/T765.1-2001 standard less than 1.1 times of isometric offset resistance.
6, special surface is handled, anti-illumination and environmental aging, dielectric strength>12KV.
7, multiple design is suitable for various leads and connects, join domain wide (10mm2-400mm2).
8, mechanical performance: the joint grip meets the GB2314-1997 requirement.
9, temperature rise performance: under big current conditions, the temperature rise of joint is less than the temperature rise that connects lead.
10, thermal stability: thermal stability is good, meets national relevant regulations requirement.
11, corrosion resistance: in sulfur dioxide and salt mist environment, do 3 times 14 days loop test, qualified.
12, environmental aging performance: in the environment in ultraviolet ray, drying, humidity, high temperature, severe cold, high height above sea level field, all can normally use.

Fig. 2 is the installation diagram of Fig. 1.
Fig. 3 is the outline drawing of cover in the double end shown in Figure 1.
Fig. 4 is the profile of Fig. 3.
Fig. 5 is the profile of tapered jacket shown in Figure 1.
Embodiment
Fig. 1, Fig. 2 illustrate, and cover 3 is by the identical left part of left-right symmetric, structure with right part is integrated constitutes in this two-way rotary extrusion type spinning electrical connector double end; This left side part is made up of the reducing shrink cylinder of a cylinder and outer end thereof, and cylinder that should left side part is provided with external screw thread 3a, and this reducing shrink cylinder is divided into two identical tapered jackets of 4～8 tongue pieces 1,2 through axial cut-outs; Have in it by cylindrical hole and round taper hole to be connected a through hole that forms, and have on the position of this cylindrical hole with double end in the internal thread that spins of the external screw thread that puts.
Referring to Fig. 3, Fig. 4, cover 3 middle parts are provided with turret head 3b (or anistree head) in the double end, so that use the spanner turn.
Referring to Fig. 5, the integrated turret head (two tapered jackets all have turret head, so that use spanner to pull) that is provided with on the tapered jacket.The osculum diameter of the through hole of tapered jacket is slightly less than the metal core wire diameter of lead, so that the metal core wire of lead is inserted.During use; The insulating barrier of the blank area of two leads is peelled off; The metal core wire of the lead through hole from tapered jacket is inserted, re-use spanner one and tapered jacket is screwed in the double end puts, along with the increase of the screw-in depth of tapered jacket; A plurality of tongue pieces of cover increase the clamping force of metal core wire thereupon in the double end, form and are electrically connected with crimping.
Installation method:
1, each series of adapters and cable are when installing and using, and product must be corresponding one by one with suitable lead, do implement concrete operations with reference to " the corresponding adapted table with cable of joint ".
2, if cover opening elastic tightening in installing and using process in meeting can be with the suitable distending of screwdriver when influence the lead insertion, and then the insertion lead, can not influence the product result of use like this.
3, non-bare wire cable, it is tapered to cut insulated hull; During utilization spanner locking lead, a spanner should be pressed in joint slope root, and the another spanner is stuck on the outer cap turret head, firmly it is wrenched (noting: when the locking lead, must it be wrenched with spanner).
4, lead insert the length of cover in the joint can be with reference to hole depth Laian County dress in this joint, inside and outside cap tightens the degree minimum requirements and is as the criterion with inside and outside cap contact point only surplus one or two screw threads.
5, if screw thread does not damage, this product is reusable.
