DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The electric wire insulation displacement connector 1 in this embodiment is a connector capable of electrically connecting a plurality of electric wires, and in particular, capable of connecting a plurality of electric wires having different diameters. The electric wire has a core wire made of a plurality of conductive metal wires and an insulating coating that covers the outside of the core wire. The wire insulation displacement connector 1 comprises at least a conductive member 2 . FIG. 1 is a schematic diagram of a conductive member.

[0016] The conductive member 2 is a conductive (metallic) member for electrically connecting a plurality of electric wires. The conductive member 2 has a number of grooves 3 (3A, 3B, 3C described below). A plurality of grooves 3 are arranged in the conductive member 2 at predetermined intervals. Each of the grooves 3 is a groove that extends substantially linearly and is open on the upper side (hereinafter, sometimes referred to as an upper groove). In the conductive member 2, the side where the groove 3 is open is the upper side, and the side opposite the upper side is the lower side. The groove 3 includes a tapered portion 31 near the opening, and a straight portion 32 extending straight from the tapered portion 31. In another embodiment, the tapered portion 31 may not be present and only the straight portion 32 may be present. The plurality of grooves 3 are arranged along a direction (x direction or z direction in FIG. 1) perpendicular to the direction in which the grooves 3 extend (y direction in FIG. 1).

[0017] A method for connecting the electric wire W to the conductive member 2 will be described. The electric wire W placed on the tapered portion 31 of the groove 3 is pushed downward along the groove 3, whereby the coating of the electric wire W is cut by the side end of the conductive member 2 constituting the groove 3. As a result, the conductive member 2 and the core wire come into contact with each other inside the groove 3, and the conductive member 2 and the electric wire W are electrically connected to each other.

[0018] At least one of the plurality of grooves 3 in the conductive member 2 has a width different from the widths of the other grooves 3. The conductive member 2 in this embodiment has three types of grooves 3 each having a different width. The conductive member 2 includes a first groove 3A having the greatest width, a second groove 3B having a width smaller than that of the first groove 3A, and a third groove 3C having a width smaller than that of the second groove 3B. This configuration makes it possible to more stably hold a plurality of electric wires of different diameters.

[0019] The straight portion 32 of the first groove 3A is, for example, 1.25 to 2.0 mm 2 The width may be optimized for connecting an electric wire having a core wire of 10 mm or more. The straight portion 32 of the second groove 3B is, for example, 0.5 to 0.85 mm. 2 The width may be optimized for connecting an electric wire having a core wire of 10 mm or more. The straight portion 32 of the third groove 3C is, for example, 0.18 to 0.36 mm. 2 The width may be optimized for connecting an electric wire having a core wire of 10 mm or more.

[0020] The conductive member 2 is bent along the direction in which the plurality of grooves 3 are arranged. In Fig. 1, the conductive member 2 is bent along a horizontal direction (x or z) perpendicular to the vertical direction y. In this embodiment, the conductive member 2 is bent along the arrangement direction to have a substantially hexagonal (annular) shape. With this configuration, the wire insulation displacement connector 1 can be made more compact. In another embodiment, the conductive member may be in the shape of a non-circular arc that curves along the direction in which the multiple grooves are arranged. In other embodiments, when the conductive member is annular, it may be substantially circular or polygonal.

[0021] The conductive member 2 includes six units that form each side of a substantially hexagonal shape. Each unit has at least one groove 3 . Among the multiple units, the width of the grooves 3 in each pair of opposing units is the same. As shown in FIG. 1, for example, a unit having a first groove 3A and an opposing unit similarly have a first groove 3A.

[0022] The width of the groove 3 in a first unit, which is one of the multiple units, is different from the width of the groove 3 in the second unit and the third unit adjacent to the first unit. As shown in FIG. 1, the unit adjacent on one side to the unit having the first groove 3A has the second groove 3B, and the unit adjacent on the other side has the third groove 3C.

[0023] In other embodiments, the conductive member may have two or more grooves in each unit. In other embodiments, the conductive member may include units that do not have grooves. The conductive member 2 in this embodiment includes three types of grooves 3 each having a different width as described above, but in other embodiments, it may include at least two or more types of grooves each having a different width.

[0024] FIG. 2 is a schematic diagram of the conductive member 2 and the holding member 4 (hereinafter referred to as the first holding member 4). The wire insulation displacement connector 1 may include a first holding member 4 . The first holding member 4 is an insulating member (made of synthetic resin) for holding the conductive member 2. The first holding member 4 is located below the conductive member 2.

[0025] FIG. 3 is a top view (the view shown in the upper part) and an AA end view (the view shown in the lower part) of FIG. The first holding member 4 has a groove for accommodating the conductive member 2 (hereinafter, referred to as an accommodating groove 41). The accommodation groove 41 is a groove provided in the first holding member 4 so as to have a substantially hexagonal shape similar to that of the conductive member 2 (so as to correspond to the shape of the conductive member 2) when viewed from above. As shown in the AA end view of FIG. 3, the lower portion of the conductive member 2 is embedded in the accommodating groove 41, whereby the conductive member 2 is held by the first holding member 4. The overall shape of the first holding member 4 may be a substantially hexagonal shape corresponding to the receiving groove 41, as shown in FIG.

[0026] FIG. 4 is a first diagram showing the wire insulation displacement connector 1 in use. FIG. 4 shows the electric wire insulation displacement connector 1 in a state where three electric wires are connected. The three electric wires shown in FIG. 4 are a first electric wire W1 which is the thickest, a second electric wire W2 which is thinner than the first electric wire W1, and a third electric wire W3 which is thinner than the second electric wire W2.

[0027] The two opposing first grooves 3A hold the first electric wire W1, the two corresponding second grooves 3B hold the second electric wire W2, and the single third groove 3C holds the third electric wire W3. The first electric wire W1 and the second electric wire W2 may be sandwiched between two grooves 3, or the third electric wire W3 may be sandwiched between only one groove 3. Each electric wire W is not only held by being clamped in the corresponding groove 3, but is also electrically connected to other electric wires via the conductive member 2 as described above.

[0028] The first holding member 4 may have a groove for receiving the clamped electric wire W (hereinafter, referred to as a receiving groove 42). The receiving groove 42 is provided at a position corresponding to the groove 3 of the conductive member 2 . The groove 3 of the conductive member 2 may be configured so that the lower end (bottom) of the groove 3 is located inside the receiving groove .

[0029] FIG. 5 is a second diagram showing the wire insulation displacement connector 1 in use. FIG. 5 is a diagram showing a state in which a cover member 5 is attached above the first holding member 4 shown in FIG. The cover member 5 is an insulating member (made of synthetic resin) for covering the upper part of the conductive member 2. The cover member 5 has a shape corresponding to the first holding member 4. The cover member 5 has an accommodating groove for accommodating the conductive member 2, although this is not shown. The cover member 5 may have a receiving groove 51 having a shape corresponding to the receiving groove 42 of the first holding member 4 at a position corresponding to the receiving groove 42 .

[0030] 3 and other figures, the first holding member 4 may have a recess 43 in a region (hereinafter, sometimes referred to as a central region) surrounded by the annular conductive member 2 (accommodating groove 41). With this configuration, the plurality of electric wires W can be prevented from becoming bulky upward in the central region where the electric wires intersect, so that the cover member 5 can be attached to the first holding member 4 more reliably. The recess 43 may have the same shape as the conductive member 2 (approximately hexagonal) when viewed from above as in this embodiment, or may have another polygonal or circular shape in other embodiments. In this embodiment, the recess of the first holding member 4 has a bottomed recess shape, but in other embodiments, the first holding member may have a through hole.

[0031] An electric wire insulation displacement connector 1' will be described as another embodiment different from the embodiment described with reference to Figs. FIG. 6 is a diagram illustrating the wire insulation displacement connector 1'. FIG. 7 is a cross-sectional view taken along line BB of FIG.

[0032] As shown in FIG. 6, the wire displacement connector 1' has an external appearance in which the wire displacement connector 1 described above in FIGS. 1 to 5 is combined with another wire displacement connector 1, which is inverted upside down. However, as shown in FIG. 7, a conductive member 2' in the electric wire insulation displacement connector 1' penetrates a holding member 4' (hereinafter referred to as a second holding member).

[0033] As shown in FIG. 6, the upper end of the conductive member 2′ has an upper groove 3U which is a groove that opens upward, and the lower end of the conductive member 2′ has a lower groove 3D which is a groove that opens downward. The insulating second holding member 4' is located between the upper groove 3U and the lower groove 3D and holds the conductive member 2'.

[0034] Although the present invention has been described in detail above, the present invention is not limited to the above-described embodiment, and various modifications and improvements are possible without departing from the gist of the present invention. [Explanation of symbols]
