Abstract
The current connector is used for detachably connecting a cylindrical wiring terminal for outputting current of an electric appliance and an external wire, and belongs to a line connecting piece. The terminal clamping mechanism of the connector comprises an inner sleeve and an outer sleeve and a back nut, wherein the inner sleeve is in a multi-petal shape, the inner sleeve and the outer sleeve are sleeved in a conical wall, and the back nut axially extrudes the outer sleeve to generate radial component force so that the inner sleeve tightly clamps a terminal. The current connector has good electrical contact with the cylindrical terminal, uniform radial stress of the terminal, large clamping force and firm connection.
Description
The binding post that the invention relates to the electrical equipment projected current is the detachable jointing between cylindrical binding post and the outer lead particularly, belongs to line connector.
Various high and low pressure electrical equipment such as transformer, sleeve pipe are all by the binding post projected current, this binding post has screw shaped, perforated plate shape and cylindrical kinds such as (comprising round bar shape and tubular), and various binding posts all are connected and output current with outer lead by line connecting joint.It not only requires firmly to join between joint and the terminal, guaranteeing doing unlikely getting loose of time spent in wind and snow loading or short circuit current electromagnetic force, and needs the electric contact that keeps good, promptly very little contact resistance, and unlikely heating damaged when electric current was passed through.In the prior art, the current joint of cylindrical binding post adopts the hood type clamping connection more, and lock with bolt at the two ends of anchor ear.Because anchor ear promptly reduces rapidly to two ends from the middle part the distribution of forces inequality of cylindrical binding post, so insufficient clamping force, terminal easily breaks away from, and the bad contact between the anchor ear makes electric current reality by area half less than the apparent area, thereby resistance is big, and heating damages easily.
In view of this, the purpose of this invention is to provide a kind of current joint that is used for cylindrical terminal, its with terminal between have good electric contact and evenly, firm grip power.
One end of current joint of the present invention is the clamp system that connects cylindrical terminal, and the other end is to hold line mechanism with the outer lead that grafting, amplexis or alternate manner connect.Its terminal clamp system is made up of inner sleeve, outer tube and back tightening nut, and the tube wall wall of inner sleeve has several axial pass troughs and is many flaps, and its external diameter is cumulative towards the pipe end direction, thereby the outer wall belt tapering; Outer tube is placed in outside the inner sleeve, and its internal diameter is less than the external diameter of inner sleeve pipe end, and cumulative to the pipe end direction, thereby the inner wall belt tapering; Back tightening nut is connected with the bottom thread of inner sleeve.And axial compression outer tube and outer tube is advanced to the pipe end direction.In this process, outer tube is converted into radial load and clamps terminal securely by the flap tube wall the axial force of inner sleeve tapered wall face.The line mechanism of holding that current joint of the present invention connects outer lead can be a tubulose, also can be Hough or anchor ear shape structure, respectively with peg graft, the mode of amplexis is held lead with a firm grip.This current joint inner sleeve with hold line mechanism and fuse, be referred to as body.Body can be that identical material is made, and also can and hold line mechanism by the inner sleeve made with unlike material and be welded mutually, selects for use according to the material of terminal and outer lead is identical or different in actual the use.If terminal and lead are with a kind of material (as copper), then body is also made by identical material (copper), if the terminal material is a copper, lead material is an aluminium, and then body should be selected the connector that copper, aluminium weld mutually for use.
Current joint of the present invention adopts many valvular structures of internal and external casing taper wall and inner sleeve, and the electric current of terminal conducts by whole even tube wall, and electric contact is good, and resistance is little, is difficult for heating and damages.
Below by the description of drawings embodiments of the invention.
Fig. 1 is an example structure figure of current joint of the present invention.
Fig. 2 is the bulk junction composition of Fig. 1 embodiment.
Fig. 3 is another example structure figure of current joint of the present invention.
Among Fig. 1 embodiment, lead 7 is held line mechanism 6 with tubulose and is plugged, inner sleeve and lead tubulose are held line mechanism and are fused as shown in Figure 2, among Fig. 1 and Fig. 2, inner sleeve 8 outer walls are tapered, and tube wall has the axial pass trough a of symmetrical distribution, and is many flaps, the middle part car of body has external screw thread b, and cylindrical terminal 1 is pegged graft with inner sleeve 8.Outer tube 10 is placed in outside the inner sleeve, and its inwall tapering is consistent with the outer wall tapering of inner sleeve, and the taper wall of internal and external casing contacts, and nut 9 screws in screw thread b and advances the also bottom of axial compression outer tube 10 to the terminal direction, and outer tube promptly advances to the pipe end direction.Its propulsive force acts on inner sleeve by the taper wall and produces radial load and makes inner sleeve be subjected to radial compression to clamp terminal.
Fig. 3 is an alternative embodiment of the invention, and among this embodiment, the line mechanism of holding of lead 7 is a half slide structure, but Hough 11 connect and folding with hinge, hold behind the lead with bolt 12 lockings.Being " T " word between lead 7 and the cylindrical terminal 1 in the present embodiment is connected.
The tapering recommendation of taper wall is 1: 3～1: 15 among this two embodiment.
For preventing the couple corrosion of different metal, can be coated with one deck damp-proof paint at the boundary of two kinds of metal materials (as copper and aluminium), prevent that the moisture content intervention from forming primary cell.In addition, be the power of reducing friction, contact between the conical surface the reduce friction polytetrafluoroethylene of coefficient of plating one deck with overcoat at body.
