Abstract

The utility model discloses a wire connection fixing device, which comprises an end button, a copper bar, an elastic copper sheet, and a wire pressuring screw, wherein the end button is cuboid, junction square holes are arranged on an end face, and tops of the junction square holes are provided with installation screw holes; the copper strip is cuboid and flat; the elastic copper sheet is an inverted triangular shape, a lower part of which is opening design, and an upper part of which is provided with a circular hole greater than the installation screw holes; the copper bar and the elastic copper sheet are respectively inserted into the junction square holes, and the copper bar is arranged below the elastic copper sheet; a wire coupling end is inserted into the elastic copper sheet, the wire pressuring screw through the installation screw holes arranged on the end button and the circular hole of the elastic copper sheet fixes the wire coupling end, and completely attaches with the contact surface of the copper bar of the lower part. The surrounding of a wire connection end provided by the utility model is forced to be fixed on the central position of the elastic copper sheet, guaranteeing the electrical connection performance thereof, effectively preventing the wire from vibrating upon shaking, and avoiding the loose phenomenon of the conducting joint.

Description

A kind of wire is connected and fixed device
Technical field
The utility model relates to a kind of wire and is connected and fixed device.
Background technology
General wire connecting ends head inserts in terminal wiring hole, the main line pressing bolt that relies on terminal top is fixed on wire in terminal, when wire is easy to occur left and right vibration in the time being subject to (producing when line pressing bolt is moved) spin friction power downwards, while particularly inserting the wire of less wire diameter, thereby it is loosening to make to conduct electricity junction, increases resistance heat; Because wiring hole is circular hole design, and wire itself is also a circle, and conductive area space is between the two larger, can not ensure the stability of electric conductivity, thereby can shorten the useful life of circuit, increases the maintenance rate of circuit.In order to address the above problem, some ways are to insert the copper billet of one " protruding " shape at wiring circular hole lower opening place, to increase wire conductive area, but when insert be the wire of less wire diameter time, still can (produce) spin friction power downwards when line pressing bolt is moved being subject to time, there is left and right vibration phenomenon in wire; Also the way having is one block of the riveting metal with circular arc below screw, but makes poor reliability because sheet metal easily falls down.
Utility model content
The purpose of this utility model is to provide a kind of wire to be connected and fixed device in order to address the above problem.
The technical scheme that the utility model adopts is:
A kind of wire is connected and fixed device, a kind of wire is connected and fixed device, comprise terminal, copper bar, elastic copper sheet, line pressing bolt, it is characterized in that, described terminal is rectangular-shaped, its end face is provided with wiring square hole, the top of wiring square hole is provided with installation screw, its installation screw is vertical with wiring square hole, the top of described elastic copper sheet is provided with the circular hole corresponding with installation screw, described copper bar and elastic copper sheet insert respectively in wiring square hole, described copper bar is positioned at elastic copper sheet below, line pressing bolt is fixed wire connecting ends through the installation screw above terminal and the circular hole of elastic copper sheet,
Further, the circular hole of described elastic copper sheet top is greater than installation screw;
Further, described elastic copper sheet is upside-down triangle shape, the lower opening corresponding with the circular hole of elastic copper sheet, and be provided with angle;
Further, the thickness of described elastic copper sheet is 0.5mm ~ 0.8mm;
Further, described copper bar both sides are provided with ledge.
The beneficial effect that the utility model produces is: can better wire be fixed in terminal wiring hole, prevent wire generation vibration, it is loosening to avoid conducting electricity junction, reduce the generation of resistance heat, thereby ensure the stability of electric conductivity, the useful life of extension wire, the maintenance rate of reduction circuit.
Brief description of the drawings
Figure 1 shows that the utility model terminal schematic diagram;
Figure 2 shows that the utility model copper bar schematic diagram;
Figure 3 shows that the utility model elastic copper sheet schematic diagram;
Figure 4 shows that the utility model fixes little wire diameter wire connecting ends schematic diagram;
Figure 5 shows that the utility model fixes large wire diameter wire connecting ends schematic diagram.
Embodiment
Terminal 1 as shown in Figure 1, is rectangular-shaped, is brass material, and its end face is provided with wiring square hole 2, and the top of wiring square hole 2 is provided with installation screw 9.
Copper bar 3 as shown in Figure 2, is cuboid flat, and its both sides are provided with outstanding position, is wiring square hole terminal and copper bar location.
Elastic copper sheet 4 as shown in Figure 3, is upside-down triangle shape, and its below is opening design, and its top is provided with the circular hole 6 that is greater than installation screw, and the thickness of elastic copper sheet is 0.5mm ~ 0.8mm.
Fix as shown in Figure 4 little wire diameter wire connecting ends schematic diagram, be screwed into line pressing bolt 5 in the position of installation screw 9, when tightening, line pressing bolt 5 directly runs through the circular hole 6 of elastic copper sheet 4, by fixing little wire diameter wire connecting ends 7, little wire diameter wire connecting ends 7 be subject to line pressing bolt 5 tighten press down fixing in again with below the contact-making surface of copper bar 3 fit completely; Meanwhile, the both sides of little wire diameter wire connecting ends 7 have been subject to again the elastic force extruding of elastic copper sheet 4, make its left and right can only be fixed on the center (being the center of wiring square hole 2) of elastic copper sheet 4; By the cooperation of above terminal 1, copper bar 3, elastic copper sheet 4 and line pressing bolt 5, make the equal energy up and down of little wire diameter wire connecting ends 7 stressed, thereby ensure its conduction switching performance, effectively prevent that wire from vibration occurring in the time being subject to vibrating, avoided the loosening phenomenon of conduction junction.
Fix as shown in Figure 5 large wire diameter wire connecting ends schematic diagram, it is the same with the method for fixing little wire diameter wire connecting ends.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
