[First embodiment]

  FIG. 1 is a perspective view showing a conducting wire used in a first embodiment of a conducting wire connecting method according to the present invention.

  In FIG. 1, reference numeral 10 generally indicates a conducting wire, and the conducting wire 10 has a conductor 14 composed of a plurality of conductive thin plates 12 stacked so as to directly contact each other. The conductive thin plate 12 may be a strip-like thin plate of metal having excellent conductivity such as gold, copper, aluminum, or an alloy thereof. In the illustrated embodiment, each conductive thin plate 12 has the same rectangular cross-sectional shape and cross-sectional dimensions.

  The conductive thin plate 12 is encapsulated by a cylindrical reinforcing layer 16 having a rectangular cross section, and the reinforcing layer 16 is encapsulated by a cylindrical covering 18 having a rectangular cross section. The reinforcing layer 16 is formed of a material having electrical insulation properties such as rubber and resin and excellent in elasticity, and imparting an appropriate compressive stress to the plurality of conductive thin plates 12 from the periphery thereof, and thereby the plurality of conductive thin plates 12. Are held as if they were one conductor. Further, the coating 18 is formed of a material having an electrical insulation property such as a resin such as vinyl chloride and having excellent deformability and weather resistance, and protects the conductive thin plate 12 and the reinforcing layer 16.

  Next, a method of connecting the two conductive wires 10 configured as described above will be described with reference to FIGS. In FIG. 2 to FIG. 9, one lead wire is indicated by a symbol with A, and the other lead wire is indicated by a symbol with B.

  First, as shown in FIG. 1, the coating 18 at the ends of the two conductors 10 is cut off, and a reinforcing layer 16 having a certain length from the ends of the coating 18 remains and is longer than the remaining length of the reinforcing layer 16. The reinforcing layer 16 is cut so that the conductive thin plate 12 extends from the end of the reinforcing layer 16 long (step A1). Next, as shown in FIG. 2, the tips of the conductive thin plates 12 of the two conductive wires 10 are moved away from each other in the stacking direction of the conductive thin plates 12, thereby separating the tips of the conductive thin plates 12 from each other (step A2). .

  Next, as shown in FIG. 3, the two conductive wires are positioned so that the plate surfaces of the conductive thin plates 12A and 12B are parallel to each other and the two conductive wires 10A and 10B form an acute angle, and in this state, the conductive thin plate 12A. And the tip of the conductive thin plates 12A and 12B are engaged with each other so that the tips of the conductive thin plates 12A and 12B are alternately arranged in the thickness direction. (Step A3).

  Next, as shown in FIG. 4, the angle formed by the two conductors 10A and 10B is increased while maintaining the state where the tips of the conductive thin plates 12A and 12B are alternately arranged, and the axis 20A of the two conductors is increased. And the extending direction of the two conducting wires 10A and 10B is changed along the plate surface of the thin plate around the tips of the conductive thin plates 12A and 12B until the two wires 20B extend in parallel with each other (step A4). . As shown in FIG. 5, the overlapping margin of the conductive thin plates 12A and 12B at this stage is small.

  Then, as shown in FIG. 6, the two conductors 10A and 10B are pressed in directions toward each other along the parallel axes 20A and 20B, thereby causing the conductive thin plates 12A and 12A and The overlap margin of 12B is increased (step A5).

  Next, as shown in FIG. 8, an electrically insulating tape 22 is wound around the conductive thin plates 12A and 12B to apply a compressive stress to the conductive thin plates 12A and 12B from the surroundings. As shown, the contact surface pressure of the conductive thin plates 12A and 12B is increased to fix the conductive thin plates 12A and 12B in a crimped state, and the connection of the two conductors 10A and 10B is completed (step A6).

  As shown in FIG. 10, a cover 26 having a shape in which a slit 24 is formed in the longitudinal direction of the covering 18 may be attached to a connecting portion between the two conducting wires 10 </ b> A and 10 </ b> B. Further, in that case, the slit 24 may be closed by an electrically insulating tape after the cover 26 is mounted, and the gap between the both ends of the cover 26 and the two conductors 10A and 10B and the coverings 18A and 18B is electrically insulating. It may be blocked by a tape.

  Thus, according to the illustrated first embodiment, the conductive thin plates 12A and 12B of the two conductors 10A and 10B are arranged alternately and integrated with the electrically insulating tape 22 in close contact with each other. Therefore, it is possible to connect the conductive wires well and firmly without requiring a special tool and without causing environmental pollution due to lead of solder.

Further, according to the first embodiment shown in the drawing, the tape 22 wound around the plurality of conductive thin plates 12A and 12B is partially or completely removed, or the tape 22 is formed along the axes 20A and 20B by the blade. After the incision is made, the connection state of the two conductors can be easily released simply by pulling the two conductors 10A and 10B away from each other.
[Second Example]

  FIG. 11 is a perspective view showing a terminal member used in the second embodiment of the connecting method of the conducting wire according to the present invention.

  In FIG. 11, reference numeral 30 denotes a terminal member as a whole. The terminal member 30 includes a conductive terminal plate 32 such as a copper plate, and a plurality of conductive thin plates 34 stacked so as to be in direct contact with each other. And a lock cover 36 made of rubber or resin having elasticity and electrical insulation. The lock cover 36 fixes the plurality of conductive thin plates 34 to the terminal plate 32 in a state where the plurality of conductive thin plates 34 abut against each other and is pressed against the terminal plate 32, and is attached to the conductive thin plate 34 and the terminal plate 32. On the other hand, they can be displaced relative to each other in the longitudinal direction.

  Next, a method for connecting the conductive wire 10 and the terminal member 30 configured as described above will be described with reference to FIGS. In these drawings, the same members as those shown in FIG. 1 are denoted by the same reference numerals as those shown in FIG.

  First, as in the case of the step A1 of the first embodiment described above, the coating 18 at the end of the conductor 10 is cut off, and the reinforcing layer 16 having a length remaining from the end of the coating 18 remains and the reinforcing layer 16 is formed. The reinforcing layer 16 is cut so that the conductive thin plate 12 extends from the end of the reinforcing layer 16 longer than the remaining length (step B1).

  Next, although not shown in the figure, as in the case of step A2 in the first embodiment described above, the conductive thin plate 12 of the conductive wire 10 is made conductive by squeezing the tip of the conductive thin plate 12 in the stacking direction of the conductive thin plate 12. The distal ends of the thin plates 12 are separated from each other, and the distal ends of the conductive thin plates 34 of the terminal member 30 are moved away from each other in the stacking direction of the conductive thin plates 34, thereby separating the distal ends of the conductive thin plates 34 from each other (step B2). .

  Next, as shown in FIG. 12, the conducting wire 10 and the terminal member 30 are positioned so that the plate surfaces of the conductive thin plates 12 and 34 are parallel to each other and the conducting wire 10 and the terminal member 30 form an acute angle. By pressing the leading end portions of the conductive thin plates 12 and 34 along the plate surface of the thin plate, the conductive thin plates 12 and 34 are arranged so that the leading end portions of the conductive thin plates 12 and 34 are alternately arranged in the thickness direction. The tip is engaged (step B3).

  Next, as shown in FIG. 13, while maintaining the state where the tips of the conductive thin plates 12 and 34 are alternately arranged, the angle formed by the conductor 10 and the terminal member 30 is increased, and the axis 20 of the conductor 10 and Until the axis 38 of the terminal member 30 extends in parallel with each other, the extending direction of the conducting wire 10 and the terminal member 30 is changed along the plate surface of the thin plate around the tips of the conductive thin plates 12 and 34. (Step B4). The overlapping margin of the conductive thin plates 12 and 34 at this stage is small.

  Next, as shown in FIG. 14, the conductor 10 and the terminal member 30 are pressed toward each other along the axes 20 and 38 parallel to each other, thereby increasing the overlap margin of the conductive thin plates 12 and 34 (process). B5).

  Next, as shown in FIG. 15, the lock cover 36 is moved in the longitudinal direction relative to the conductive thin plate 34 and the terminal plate 32 so that the lock cover 36 approaches the conductor 10, and the conductive thin plate 12 and 34, an electrically insulating tape 22 is wound around the conductive thin plates 12 and 34, thereby applying a compressive stress to the conductive thin plates 12 and 34, and increasing the contact surface pressure of the conductive thin plates 12 and 34. 34 is fixed in a crimped state, and the connection of the conducting wire 10 and the terminal member 30 is completed (step B6).

  Thus, according to the second embodiment shown in the drawing, the lock cover 36 and the tape in a state where the conductive wires 12 and the plurality of conductive thin plates 12 and 34 of the terminal member 30 are alternately arranged in the thickness direction and in close contact with each other. Since they are integrally held by the wire 22, the lead wire and the terminal member can be connected well and firmly without requiring a special tool and without causing environmental pollution due to lead of solder.

  Further, according to the second embodiment shown in the drawing, after the lock cover 36 that integrally holds the plurality of conductive thin plates 12 and 34 is moved away from the conductive wire 10, the conductive wire 10 and the terminal member 30 are connected to each other. Only by pulling away, the connection state of the conducting wire and the terminal member can be easily released.

  According to the first and second embodiments described above, the tips of the conductive thin plates 12 and 34 are spaced apart from each other by rubbing the tips of the conductive thin plates 12 and 34 in the stacking direction of the conductive thin plates. Therefore, as compared with the case where this step is not performed, the step of meshing the leading end portions of the two types of conductive thin plates so that the leading end portions of the conductive thin plates 12A and 12B or the conductive thin plates 12 and 34 are alternately arranged.

However, as shown in FIG. 16, the lock cover 36 may be moved to the overlapping portion of the conductive thin plates 12 and 34, and in that case The winding of the tape 22 may be omitted. Also in this case, a part of the conductive thin plate of the conductive wire 10 or the terminal member 30 may be cut off as necessary.
