Abstract
The utility model discloses a columnar copper and aluminum wire connecting terminal which is composed of a fixing piece and a connecting piece made of copper or aluminum, wherein the fixing piece and the connecting piece are integrated, one end of the connecting piece is extended out from the fixing piece on which screwed holes are arranged, the connecting piece is a solid columnar body, and the end face of the connecting piece is a circular welding face. The columnar copper and aluminum wire connecting terminal has a structure that identical or different metal conducting wires are welded on the end face of the connecting piece, the connection is reliable, and the effect of electric rot does not occur on a welding joint; the operation of welding can be carried out in a reinforced sleeve for welding seams; the wire connecting terminal can be applied to the field of midfrequency or high frequency welding and is suitable for friction welding; and the utility model is suitable for lead wires of railway steel rails, external cable terminals of electric accessories and electrical connecting wires.
Description
Technical field
The utility model relates to a kind of binding post, especially relates to a kind of column copper al wiring terminal that is mainly used in the railway track lead wire.
Background technology
In the prior art, the end that copper al wiring terminal connects plain conductor is tubular, will weld or crimping in the plain conductor insertion tube in the application.This connected mode can not realize the reliable connection of dissimilar metal lead, and along with the prolongation of conduction time, the galvano-cautery effect takes place the heating of welding point place easily, is difficult to satisfy the use needs.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, a kind of column copper al wiring terminal is provided, its connector is solid column, of the same race or the dissimilar metal lead of welding on the connector end face, connect reliable, the welding point place does not produce the galvano-cautery effect, can implement welding in the weld seam reinforcing sleeve, and application is wide.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of column copper al wiring terminal, fixture and the connector made by copper or aluminium constitute, described fixture and connector are an overall structure, connector one end stretches out fixture, have screwed hole on the described fixture, it is characterized in that: described connector is solid column, and the connector end face is the circular weld face.
Described circular weld face area is 30-300mm

The utility model compared with prior art has the following advantages: 1, connect reliably, the welding point place does not produce the galvano-cautery effect.The utility model connector is solid column, and the connector end face is the circular weld face, is welded to connect of the same race on the connector end face or the dissimilar metal lead, when conduction, the welding point place that this end face is welded to connect connects reliable, does not generate heat, and does not produce the galvano-cautery effect.2, can implement welding in the weld seam reinforcing sleeve, cost is little, is convenient to mechanically actuated operation.3, the utility model can be applied in middle and high frequency welding field, and suitable friction welding.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Description of reference numerals:
1-fixture; 2-connector; 3-screwed hole;
4-connector end face.
Embodiment
A kind of column copper al wiring terminal as depicted in figs. 1 and 2, fixture 1 and the connector 2 made by copper or aluminium constitute.Fixture 1 and connector 2 are an overall structure, and connector 2 is solid column, and connector 2 one ends stretch out fixture 1.Connector end face 4 is the circular weld face, and the area of circular weld face is 30-300mm
2Have screwed hole 3 on the fixture 1.
The utility model uses when of the same race or dissimilar metal wire bonds, selects copper material or aluminium material as required.At the connector end face is the of the same race or dissimilar metal lead of welding on the circular weld face, and it connects reliable, and the welding point place does not generate heat, and does not produce the galvano-cautery effect.The utility model can be implemented welding in the weld seam reinforcing sleeve.
The utility model is applicable to railway track lead wire, the outer terminal of electric power annex cable and electric connection line.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection range of technical solutions of the utility model.
