The clamp 301 also includes a wire holding plate 302 connected to the wire holding portion 310 by pins 320 . In this clamp 301, the movable contact table 312 is lifted so that the contact blade 311 comes into contact with the coating (insulating coating) of the electric wire and penetrates the coating.

The wire holding portion 310 is provided with a concave groove 315 having a width substantially equal to the diameter of a normal wire. The wire holding plate 302 is provided with a groove 323 having a width narrower than the width of the groove 315 and substantially equal to the diameter of the small-diameter wire. Further, the wire holding plate 302 can take a posture overlapping the wire holding portion 310 and a posture not overlapping the wire holding portion 310 by rotating around the pin 320 . By changing the posture of the wire holding plate 302 in the clamp 301 according to the diameter of the wire, the clamp 301 can stably hold both large and small wires. For example, when penetrating the coating of a thin electric wire, when the electric wire holding plate 302 is placed on the electric wire holding portion 310, the thin electric wire is sandwiched between the grooves 323 of the narrow electric wire holding plate 302, so that the electric wire can be stably inserted. is clamped by the clamp 301.

The fixing part 20 can be fixed, for example, to the upper jaw part 10 of the clamp 1 . Specifically, the fixing part 20 is fixed to the upper jaw part 10 by hooking the fixing means, which is part of the fixing part 20, on a part of the upper jaw part 10 (see FIGS. 1 and 4 to 7). . The fixing portion 20 of this embodiment has a pair of claw portions 201 as fixing means. Further, the fixing portion 20 of the present embodiment includes a pair of plate portions 202 respectively connected to the body portion 21 and the pair of claw portions 201, and a pair of opening/closing means 203 respectively connected to the pair of plate portions 202. have.

The pair of claws 201 are configured to be able to approach and separate from each other, and are fixed to the upper jaw 10 by hooking on both side surfaces 107 of the upper jaw 10 in the approached state (see FIG. 1). Specifically, the pair of claw portions 201 are configured to be fitted and locked to the concave portions 108 of the side surfaces 107 . Also, the pair of claw portions 201 are fixed inside the pair of plate portions 202 by fastening means (for example, bolts). More specifically, a part of the inner peripheral surface 204 of the pair of claws 201 is in surface contact with the recesses 108 of both side surfaces 107 of the upper jaw 10 (see FIG. 6).

The pair of opening/closing means 203 includes biasing means (for example, compression coil springs) biased inward. Therefore, the pair of opening/closing means 203 can be opened and closed (can be moved toward and away from each other). Specifically, the pair of opening/closing means 203 are opened (away from each other, see FIG. 7) in an outwardly biased state, and closed (close to each other, see FIG. 6) in an unloaded state. Further, the pair of opening/closing means 203 is fixed inside the pair of plate portions 202 by fastening means (for example, bolts). The inner surfaces of the pair of plate portions 202 are in surface contact with, for example, portions of both side surfaces 107 of the upper jaw 10 excluding the concave portion 108 .

With the above configuration, when the pair of opening/closing means 203 is pulled outward to open the fixing portion 20, the pair of plate portions 202 are also opened outward and the pair of claw portions 201 are separated from each other. It is removed from the upper jaw 10 (see Figure 7). In addition, when the pair of opening/closing means 203 are closed in a state where no force is applied to the fixing portion 20, the pair of plate portions 202 are also closed inward, and the pair of claw portions 201 are also brought close to each other. (see Figure 6). The pair of opening/closing means 203 may be opened by being pulled to both sides, or may be opened by being pulled outward while one is fixed.

The main body portion 21 is formed on the first inner peripheral surface of the upper jaw portion 10 so that the narrow groove 23 faces the lower jaw portion 11 when the fixing portion 20 is fixed to the clamp 1 (hereinafter also referred to as a fixed state). 101 (see FIG. 1). Further, the body portion 21 has, for example, an inner peripheral surface 230 defining the narrow groove 23 and an outer peripheral surface 231 provided on the opposite side of the inner peripheral surface 230 (see FIG. 2).

The body portion 21 has positioning means for aligning the central axis C of the wide groove 15 of the upper jaw 10 and the central axis of the narrow groove 23 of the spacer 2 . By engaging with the first inner peripheral surface 101 defining the wide groove 15 , the positioning means aligns the horizontal center axis of the narrow groove 23 with the center axis C of the wide groove 15 . , to position the narrow groove 23 .

Specifically, the inner peripheral surface 230 has a pair of inclined surfaces 232 extending horizontally on both sides of the central axis C, and a pair of flat surfaces 233 extending outward from the pair of inclined surfaces 232 . . With such a configuration of the inner peripheral surface 230, the narrow groove 23 has a tapered receiving portion 235 whose width in the horizontal direction becomes narrower toward the upper side, and a tapered receiving portion 235 that is continuous with the receiving portion 235 at the lower side and extends in the horizontal direction. and a downwardly extending portion 236 that is uniform in width. The boundary between the pair of inclined surfaces 232 and the boundary between the inclined surface 232 and the flat surface 233 are chamfered.

The outer peripheral surface 231 of this embodiment is in contact with at least a portion of the inner peripheral surface 100 of the upper jaw 10 in the fixed state. Specifically, in the fixed state, the outer peripheral surface 231 is in surface contact with the entire inner peripheral surface 100 (for example, both the pair of inclined portions 103 and the pair of flat portions 104). Thus, the outer peripheral surface 231 of the present embodiment serves as a positioning means (a positioning means for positioning the narrow groove 23 so that the central axis of the narrow groove 23 in the horizontal direction is on the central axis C of the wide groove 15). , a pair of inclined surfaces 234 are provided. Of the pair of inclined surfaces 234, the inclined surface 234 located on the doorway 12 side is inclined at the same angle as the inclined portion 103 located on the doorway 12 side of the pair of inclined portions 103 of the inner peripheral surface 100 of the upper jaw 10. ing. Also, the inclined surface 234 located on the opposite side of the entrance 12 among the pair of inclined surfaces 234 and the inclined portion 103 located on the opposite side of the entrance 12 among the pair of inclined portions 103 of the inner peripheral surface 100 of the upper jaw 10 . inclined at the same angle.

The distal end portion 22 extends in the direction in which the second inner peripheral surface 102 of the upper jaw portion 10 extends in the fixed state. Further, the tip portion 22 is arranged between the second inner peripheral surface 102 and the lower jaw portion 11 in order to narrow the entrance 12 for the electric wire in the fixed state. The distal end portion 22 of the present embodiment has an inner peripheral surface 220 that defines the entrance/exit 12 side, and an outer peripheral surface 221 located on the opposite side of the inner peripheral surface 220 . The outer peripheral surface 221 extends in a direction along the second inner peripheral surface 102 of the upper jaw 10 and faces the second inner peripheral surface 102 . As a result, the inner peripheral surface 220 is positioned below the second inner peripheral surface 102 by at least the thickness of the distal end portion 22 (thickness in the vertical direction).

With such a configuration of the tip portion 22, the width (dimension in the vertical direction) W2 of the doorway 12 in the fixed state is equal to the width W1 of the doorway 12 in the state in which the spacer 2 is removed from the clamp 1 (hereinafter also referred to as the attached state). (see Figure 1). The difference between the width W2 of the entrance 12 in the fixed state and the width W1 of the entrance 12 in the attached state is larger than the diameter W3 of the small-diameter electric wire 3 (see FIG. 8), and It is smaller than the diameter W4 (see FIG. 9).

With the configuration of the clamp 1 and the spacer 2 described above, the small-diameter wire 3 or the normal-diameter wire (where the diameter of the wire is equal to or both the horizontal width of the narrow groove 23 and the width W2 of the entrance/exit 12 in the fixed state). (Electric wire smaller than the wire) is clamped between the narrow groove 23 and the lower jaw 11 (see FIG. 8). In addition, a large-diameter electric wire 4 (the diameter of the electric wire is larger than the width W2 of the doorway 12 in the fixed state and is equal to or larger than the width W1 of the doorway in the state where the spacer 2 is removed from the clamp 1). A small wire) is clamped between the wide groove 15 of the upper jaw 10 and the lower jaw 11 (see FIG. 9).

According to the spacer 2 described above, when the spacer 2 is attached to the clamp 1 , the narrow groove 23 is arranged to face the lower jaw 11 . can be held stably (see FIG. 8). Further, in the state where the spacer 2 is attached to the clamp 1, the distal end portion 22 of the spacer 2 is arranged between the lower jaw portion 11 and the second inner peripheral surface 102 of the upper jaw portion 10 so as to narrow the entrance 12. Therefore, it is possible to prevent the large-diameter electric wire 4 from entering from the doorway 12 .

Further, in the spacer 2 of this embodiment, the spacer 2 is stably attached to the clamp 1 by hooking the pair of claws 201 on both side surfaces 107 of the upper jaw 10 of the clamp 1 .

Furthermore, in the spacer 2 of the present embodiment, the spacer 2 is securely attached to the clamp 1 by fitting and locking the pair of claws 201 into the concave portions 108 of the side surfaces 107 of the upper jaw 10 .

Since the spacer 2 of the present embodiment has positioning means for aligning the central axis C of the wide groove 15 of the upper jaw 10 and the central axis of the narrow groove 23 of the spacer 2, when attaching the spacer 2 to the upper jaw 10 Positioning between the spacer 2 and the upper jaw 10 is properly performed. Specifically, the pair of inclined surfaces 234 of the outer peripheral surface 231 of the main body portion 21 of the spacer 2 are equally inclined with the pair of inclined portions 103 of the first inner peripheral surface 101 of the upper jaw 10 (see FIG. 2). ), the spacer 2 and the upper jaw 10 are properly positioned when the spacer 2 is attached to the upper jaw 10, and the attachment of the spacer 2 to the upper jaw 10 is stabilized.

In addition, in the spacer 2 of the present embodiment, the narrow groove 23 has a tapered receiving portion 235 whose width in the horizontal direction becomes narrower toward the upper side, and the receiving portion 235 that continues to the lower side of the receiving portion 235 and has a uniform width in the horizontal direction. , the width in the horizontal direction of the lower end of the narrow groove 23 is narrowed. Therefore, when the thin wire 3 is arranged in the narrow groove 23 , the wire 3 is less likely to shift in the horizontal direction, and the wire 3 can be held more stably together with the lower jaw 11 .

Furthermore, in the spacer 2 of the present embodiment, when the pair of opening/closing means 203 are closed by being in a state where no force is applied, the fixing portion 20 is attached to the upper jaw portion 10, so attachment of the spacer 2 to the clamp 1 is difficult. The spacer 2 can be easily attached to the clamp 1 without the need for a member such as a fastening member. Further, when the spacer 2 is opened by the pair of opening/closing means 203 being urged outward, the fixing portion 20 is removed from the upper jaw portion 10, so the spacer 2 can be easily removed from the clamp 1.

It should be noted that the spacer of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, some of the configurations of certain embodiments can be deleted.

For example, the outer peripheral surface 231 of the body portion 21 of the spacer 2 may be in surface contact with only one of the pair of inclined portions 103, as shown in FIG. The outer peripheral surface 221 of the tip 22 may be far away from the second inner peripheral surface 102 of the upper jaw 10 . Specifically, the outer peripheral surface 221 of the distal end portion 22 may be arranged below the second inner peripheral surface 102 with a space therebetween. Further, the outer peripheral surface 231 of the body portion 21 may be in contact with a portion of each of the pair of inclined portions 103 as shown in FIG. 11 . Even in such a case, when the spacer 2 is attached to the clamp 1, the small-diameter electric wire 3 can be stably held in the narrow groove 23, and the large-diameter electric wire 4 from the entrance/exit 12 can be stably held. Intrusion can be suppressed.

The outer peripheral surface 221 of the distal end portion 22 may be in surface contact with the second inner peripheral surface 102 . In this case, the inner peripheral surface 220 is located below the second inner peripheral surface 102 by the thickness of the tip portion 22 (thickness in the vertical direction).

In the spacer 2 of the above embodiment, the fixed part 20 is hooked on both side surfaces 107 of the upper jaw 10 in the thickness direction, but it may be hooked on another part of the upper jaw 10 . The pair of claws 201 may be hooked on the inner peripheral surface 101 that defines the wide groove 15 of the upper jaw 10, as shown in FIG. The inner peripheral surface 101 has an upwardly extending portion 109 that extends further upward from the tapered receiving portion 105 . The upwardly extending portion 109 defines a cylindrical space. In addition, the upwardly extending portion 109 has a pair of engaging portions 110 recessed outward. The pair of locked portions 110 are, for example, opposed in the horizontal direction and define a hemispherically recessed space. As shown in FIG. 13 , the fixing portion 20 includes a pair of hemispherical claw portions 201 corresponding to the engaged portion 110 and a cylindrical portion 205 corresponding to the space defined by the upwardly extending portion 109 . , and a pair of biasing members 206 connecting each of the pair of claw portions 201 and the cylindrical portion 205 . A pair of through-holes are provided at positions facing each other in the horizontal direction on the side surface of the cylindrical portion 205 . The biasing members 206 are arranged in a pair of through holes provided in the cylindrical portion 205 .

When the fixed portion 20 enters the space defined by the upwardly extending portion 109 , the pair of claw portions 201 are pushed inward by the inner peripheral surface 101 and housed in the through holes provided in the cylindrical portion 205 . At this time, the pair of biasing members 206 are biased outward by elastically deforming so that the length in the horizontal direction is shortened. Furthermore, when the pair of claws 201 reaches the position facing the pair of locked portions 110 of the upwardly extending portion 109, the biasing force of the biasing member 206 changes the shape (length before elastic deformation) before elastic deformation. ), it is arranged in the pair of locked portions 110 and is fitted and locked to the locked portions 110 . Also in this case, the spacer 2 is reliably attached to the clamp 1 by fitting and locking the pair of claws 201 to the pair of locked portions 110 of the upper jaw 10 .

Further, in the spacer 2 of the above embodiment, a pair of claw portions 201 are provided, but one claw portion 201 or a plurality of three or more claw portions 201 may be provided. It should be noted that the means for fixing the spacer 2 may be another fixing member such as a fastening member (bolt), a magnet, or the like, other than the claw portion 201 .
