Description

  The present invention relates to an electric wire clip used for temporarily fixing a high voltage underline to a high voltage overhead electric wire.

  The high voltage underline is connected to the high voltage overhead electric wire via a branch connector. In attaching and removing the branch connector, the high voltage underline is temporarily fixed to the high voltage overhead electric wire in order to facilitate the operation. Conventionally, a wire clip that sandwiches a high-voltage underline and a high-voltage overhead wire at the same time has been used for such temporary fixing work.

  As an electric wire clip, the thing of the structure where a front-end | tip part opens by closing a base end part is common. Then, the base end of the electric wire clip is supported by the indirect hot wire tool, the base end portion is closed by operating the indirect hot wire tool, and the electric wire is inserted into and grasped by the open front end portion. Mounted on.

  Conventionally, as this type of technology, there is a technology described in Patent Document 1. Patent Document 1 discloses a mounting clip for a protective sheet that can be securely clamped even by a thin electric wire by attaching an elastic member to the inside of an arm and making the space between the arms dense with the elastic member. Is disclosed.

JP 2010-176878 A

  By the way, when the electric wire clip is attached obliquely from above with respect to the electric wire by the indirect hot wire operation, the electric wire clip rotates and moves around the distal end portion by the weight of the proximal end portion. The position of the part may shift. In this case, the worker may need to change the work position in order to remove the electric wire clip whose base end portion has shifted by indirect hot wire work.

  Moreover, in the clip of patent document 1, an elastic member is comprised by low resilience and a low restoring force like a polyurethane cushion. For this reason, when the clip of patent document 1 is used, there exists a possibility that the polyurethane cushion around an electric wire may deform | transform if the state holding the electric wire continues for a long time. For this reason, there exists a possibility that it may become impossible to hold | grip an electric wire reliably.

  An object of this invention is to provide the electric wire clip which solves such a problem and can clamp an electric wire more reliably.

  In order to achieve the above object, the present invention has the following configuration.

  (1) A pair of clip pieces each having a distal end portion extending in the longitudinal direction and a proximal end portion extending obliquely from the distal end portion, and the pair of clip pieces so that the distal end portion and the proximal end portion face each other. A plurality of gripping members that are arranged and arranged in the longitudinal direction of the distal end on the clip body that is opened and closed by the operation of the proximal end, and on the surface of the distal end that faces each other in the clip body And a spring member that is fixed to the distal end portion and supports the gripping member so as to reciprocate in a direction that makes contact with and away from the surface of the distal end portion.

  According to (1), when the electric wire clip sandwiches the electric wire, the pressing force by the spring member acts on the electric wire via the holding member, so that the force to hold the electric wire becomes strong and the electric wire is securely held. It becomes possible to do. In addition, there are a plurality of gripping members in the longitudinal direction of the clip piece, and when the wire clip sandwiches the wire, the gripping member that sandwiches the wire moves and sinks in a direction approaching the installation surface on the tip side, Other gripping members not sandwiching the electric wires are in a state of moving and floating in a direction away from the installation surface on the distal end side. For this reason, when a clip main body tries to move with respect to an electric wire, the movement of a clip main body is controlled by another holding member. Thereby, it is possible to provide an electric wire clip that is not easily displaced in a state where the electric wire is sandwiched.

  (2) In (1), one gripping member located on the most distal side of the clip piece in the plurality of gripping members is composed of one member, and the other is disposed from the one gripping member to the proximal end side The grip member is divided in the width direction of the clip piece.

  According to (2), since the grip member other than the most advanced grip member of the clip piece is divided in the width direction, for example, when the clip member is sandwiched diagonally, one of the divided grip members sinks. However, there is a portion where the position of the other gripping member does not change. For this reason, when a clip main body tries to move with respect to an electric wire, an electric wire comes to contact | abut to the other holding member which does not change a position, and it becomes possible to provide the electric wire clip which is hard to slip | deviate between the electric wires. . Further, since the most advanced gripping member of the clip piece is not divided, the most distal portion of the clip main body is blocked by the gripping member, so that it is difficult for the electric wire to come off from the most distal end portion of the clip main body. Further, for example, even when the electric wire is sandwiched near the proximal end side in the region on the distal end side where the gripping member is arranged in the pair of clip pieces, the most advanced gripping member of the clip piece urges the spring member. Therefore, the electric wire clip 1 is maintained in a state where the tip of the electric wire clip 1 is closed by the gripping member, and the pinched electric wire is difficult to come off from the tip of the electric wire clip 1.

  (3) The electric wire clip according to (1) or (2), wherein an unevenness is formed on a surface of the gripping member.

  According to (3), since the frictional force between the surface of the gripping member and the electric wire when the electric wire clip is attached to the electric wire is increased, the electric wire can be reliably held.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to hold | grip an electric wire reliably and also to provide the electric wire clip which is hard to slip | deviate in the state which pinched | interposed the electric wire.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing an appearance of an electric wire clip 1 according to an embodiment of the present invention. The electric wire clip 1 includes a clip body 10, a gripping member 14, and a coil spring 16 corresponding to a spring member.

  The clip body 10 includes a pair of clip pieces 12, 12, a connecting member 18, a shaft 20, and a torsion spring 22 (see FIG. 2).

  The clip piece 12 includes a distal end portion 12a extending in the longitudinal direction and a proximal end portion 12b extending obliquely from the distal end portion 12a. The pair of clip pieces 12 and 12 are arranged so that the tip end portion 12a and the base end portion 12b face each other, and the end portion on the base end portion 12b side of the tip end portion 12a of the pair of clip pieces 12 and 12 is a shaft. 20 are connected. For this reason, the pair of clip pieces 12 and 12 are rotatable about the shaft 20, respectively, and a pair of distal end portions 12a facing each other by operating to close the pair of proximal end portions 12b and 12b facing each other. , 12a are separated. On the contrary, a pair of front-end | tip parts 12a and 12a which oppose each other are closed by operating so that a pair of base end parts 12b and 12b which oppose each other may be opened. For the convenience of the following description, in the clip piece 12 shown in FIG. 1, the direction perpendicular to the longitudinal direction (X direction in FIG. 1) and the tip portions 12a, 12a of the pair of clip pieces 12, 12 are opposed to each other. This is referred to as the contact / separation direction (Y direction in FIG. 1). Further, in the clip piece 12 shown in FIG. 1, a direction perpendicular to the longitudinal direction and the approaching / separating direction is referred to as a width direction (Z direction in FIG. 1).

  The connecting member 18 is a rubber cylindrical member disposed around the end portion of the distal end portion 12 a of the clip piece 12 on the base end portion 12 b side. The connecting member 18 prevents the shaft 20 from falling off the clip pieces 12 and 12.

  A cutout portion 30 is formed on a surface of the tip portion 12a where the pair of clip pieces 12 and 12 face each other (hereinafter, this surface is referred to as a facing surface). The notch 30 is formed from the distal end of the distal end portion 12a toward the proximal end portion 12b.

  Further, in FIG. 1, the gripping member 14 is a rectangular parallelepiped member, and a plurality of gripping members 14 are arranged on the surface of the tip end portion 12 a that is opposed to each other in the pair of clip pieces 12 and 12 and in which the notch portion 30 is formed. ing. For this reason, the gripping member 14 comes to face each other in the pair of clip pieces 12 and 12. Further, irregularities are formed on the surfaces of the gripping members 14 facing each other in the pair of clip pieces 12 and 12. In the present embodiment, a plurality of grooves 14c extending in the longitudinal direction as irregularities are formed. The plurality of grooves 14c have a sawtooth shape when viewed from the longitudinal direction.

  The coil spring 16 is interposed between the gripping member 14 and the facing surface of the tip portion 12a, is fixed to the facing surface of the tip portion 12a, and supports the gripping member 14 so as to reciprocate in the contact / separation direction. Here, in the normal state, the coil spring 16 is set so that a part of the gripping member 14 protrudes from the surface of the distal end portion 12a where the notch 30 is not formed. The gripping member 14 is positioned in the region of the notch 30 by being pushed into the facing surface side of 12a.

  FIG. 2 is a plan view showing the configuration of the clip piece 12 and the arrangement of the gripping member 14. The clip piece 12 further includes a bearing portion 12 c, and the bearing portion 12 c is formed at an end portion on the base end portion 12 b side in the distal end portion 12 a of the clip piece 12.

  The bearing portion 12c is composed of a pair of plate-like members standing from both end portions in the width direction on the opposing surface of the tip end portion 12a, and the pair of plate-like members are formed at both end portions perpendicular to the longitudinal direction. The plate surfaces face each other. A through hole (not shown) for inserting the shaft 20 is formed on the plate surfaces of the pair of plate-like members.

  Then, after the bearing portions 12c of the pair of clip pieces 12 and 12 are overlapped so that the through holes of the bearing portion 12c coincide with each other and the torsion spring 22 is disposed between the bearing portions 12c and 12c, The columnar shaft 20 is inserted into the through hole of the bearing portion 12c. At this time, the coil portion of the torsion spring 22 is loosely fitted to the shaft 20, and both end portions of the torsion spring 22 are in contact with the inner surface of the base end portion 12b. Further, both end portions of the shaft 20 are covered with the connecting member 18.

  As described above, the pair of clip pieces 12 and 12 of the clip body 10 are rotatably connected by the shaft 20. In the normal state, the clip main body 10 is maintained in a state in which the base end portions 12b and 12b are expanded by urging in the opening direction from the torsion spring 22, and thus the distal end portions 12a and 12a are closed. For this reason, as for the electric wire clip 1, the holding members 14 which mutually oppose contact | abut in a normal state.

  Next, the configuration of the gripping member 14 will be described.

  There are two types of gripping members 14, a gripping member 14 a corresponding to one gripping member and a gripping member 14 b corresponding to another gripping member. The gripping member 14a has a shape obtained by dividing a virtual rectangular parallelepiped slightly smaller than the cutout portion 30 into four equal parts in the longitudinal direction, and the gripping member 14b further divides the virtual rectangular parallelepiped into four equal parts in the width direction. This is the shape.

  And as shown in FIG. 2, the holding member 14a is arrange | positioned at the forefront side of the front-end | tip part 12a. At this time, the gripping member 14a is arranged so that the long side is parallel to the width direction. The gripping members 14b are arranged in the longitudinal direction while being arranged in the width direction two by two from the gripping member 14a in the distal end portion 12a to the base end portion 12b side. According to this embodiment, the six gripping members 14b are arranged at the distal end portion 12a.

  The coil spring 16 (see FIG. 1) is installed at the distal end portion 12a so as to correspond to one gripping member 14a and six gripping members 14b, respectively.

Next, operation | movement of the electric wire clip 1 is demonstrated, referring FIG. 3, FIG.
FIG. 3 is a side view of the electric wire clip 1 in a normal state, and FIG. 4 is a side view of the electric wire clip 1 when the base end portions 12b and 12b are closed.

  As shown in FIG. 3, the electric wire clip 1 in the normal state is in a state in which the base end portions 12b and 12b are opened and the distal end portions 12a and 12a are closed. At this time, the gripping member 14a and the gripping member 14b facing each other are in contact with each other, and the coil spring 16 is maintained in a contracted state. For this reason, the pair of gripping members 14 a and the pair of gripping members 14 b facing each other are in a state of being pressed against each other by the urging of the torsion spring 22 (see FIG. 2) and the coil spring 16.

  When the base end portions 12b and 12b of the electric wire clip 1 in the normal state shown in FIG. 3 are closed, the distal end portions 12a and 12a are opened as shown in FIG. Further, the gripping member 14a and the gripping member 14b are in a state of protruding from the positions of the gripping member 14a and the gripping member 14b in the normal state when the coil spring 16 extends.

  Next, the attachment operation of the electric wire clip 1 of this embodiment is demonstrated, referring FIG. 5, FIG.

  First, as shown in FIG. 5, the operator operates the hot wire tool 50 to grip the proximal end portions 12 b and 12 b of the electric wire clip 1 with the grip portion 50 a of the hot wire tool 50, and further, FIG. As shown in FIG. 2, the proximal end portions 12b and 12b are sandwiched and brought into contact with the hot wire tool 50 to open the distal end portions 12a and 12a. And after an operator operates the hot wire tool 50 and inserts an electric wire between the front-end | tip parts 12a and 12a and positions between the holding members 14b and 14b which oppose each other, the base end part 12b of the electric wire clip 1 is used. , 12b is opened to hold the electric wire between the holding members 14b, 14b.

  Then, when the worker removes the hot wire tool 50 from the electric wire clip 1, the attachment of the electric wire clip 1 is completed.

  FIG. 7 is an explanatory view showing the position of the electric wire on the clip piece 12 in a state where the electric wire clip 1 is attached to the electric wire, and FIG. 8 is a view of the electric wire clip 1 of FIG.

  For example, when the electric wire clip 1 is attached obliquely to the electric wire 100, the electric wire 100 may be gripped by three or more pairs of gripping members 14b. Specifically, when the electric wire is arranged as shown in FIG. 7 with respect to the distal end portion 12a, the gripping members 14b (1), 14b (2), 14b (5), 14b shown in FIG. The electric wire 100 is gripped by the pair (6). At this time, a pair of the gripping member 14a and the gripping members 14b (3) and 14b (4) come into contact with each other. Further, the gripping members 14b (1), 14b (2), 14b (5), and 14b (6) are pushed into the facing surface side of the distal end portion 12a, and are in a state of sinking to the facing surface side from the normal state. For this reason, when the coil spring 16 contracts, the electric wire 100 is urged by the coil spring 16, and the gripping members 14 b (1), 14 b (2), 14 b (5), and 14 b (6) are paired. It is pinched.

  Further, as shown in FIG. 8, in a state where the electric wire clip 1 is attached to the electric wire 100, the grip members 14 a and 14 a positioned at the most distal end portions of the pair of clip pieces 12 and 12 are in contact with each other. That is, the most distal end portions of the distal end portions 12a and 12a are blocked by the gripping members 14a and 14a. For this reason, in the state where the electric wire clip 1 is attached to the electric wire 100, even if the electric wire clip 1 is rotated by moving the base end portion 12b of the electric wire clip 1 downward, the electric wire 100 is at the forefront of the electric wire clip 1. It is prevented from falling off through the part.

  As shown in FIG. 7, when the electric wire clip 1 is attached to the electric wire 100 at an angle, there is a pair of gripping members 14b that are in contact with each other in addition to the gripping member 14a. In the example shown in FIG. 7, a pair of the gripping member 14b (3) and the gripping member 14b (4) are in contact with each other. For this reason, even if the electric wire clip 1 rotates, the electric wire 100 comes into contact with the gripping members 14b (3) and 14b (4) that are in contact with each other, and the electric wire clip 1 is inclined with respect to the electric wire 100. The installed state is maintained.

  As described above, according to the present embodiment configured as described above, when the electric wire clip 1 sandwiches the electric wire, the urging force by the coil spring 16 together with the urging force by the torsion spring 22 via the gripping member 14 against the electric wire. Therefore, the force for gripping the electric wire is increased, and the electric wire can be securely gripped. A plurality of gripping members 14 are provided in the longitudinal direction of the distal end portion 12 a of the clip piece 12, and the gripping member 14 that sandwiches the electric wire when the electric wire is sandwiched approaches the opposing surface side of the coil spring 16 and sinks. Although it is in a state, the positions of the other gripping members 14 are not changed. For this reason, when the clip main body 10 is about to move with respect to the electric wire, the movement of the clip main body is restricted by coming into contact with the gripping member whose position has not changed. Thereby, it becomes possible to provide the electric wire clip 1 which is hard to shift in a state where the electric wire is sandwiched.

  Further, according to the present embodiment, since the gripping members 14 other than the most advanced gripping member 14 (14a) of the clip piece are divided in the width direction, for example, when the clip member is sandwiched obliquely, There is a portion where the holding member 14 (14b) is sinking but the position of the other holding member 14 (14b) is not changed. For this reason, even if it is sandwiched diagonally between the electric wires, it is possible to maintain the state of being sandwiched between the electric wires, and it is possible to provide an electric wire clip that is not easily displaced.

  Further, since the most advanced gripping member 14 a of the clip piece is not divided, the end of the electric wire clip 1 is blocked by the gripping member 14 a, and the electric wire is difficult to come off from the front end of the power supply clip 1. Furthermore, for example, even when the electric wire is sandwiched near the proximal end side at the distal end portion of the clip main body 10, the most advanced gripping member 14 of the clip piece 12 protrudes due to the bias of the coil spring 16. 1 is maintained in a state in which the tip of 1 is closed by the gripping member 14 a, it is difficult for the pinched electric wire to come out of the tip of the electric wire clip 1.

  Moreover, according to this embodiment, since the unevenness | corrugation is formed in the surface of the holding member 14, when the electric wire clip 1 is attached to an electric wire, the frictional force of the surface of the holding member 14 and an electric wire becomes high. For this reason, it becomes possible to hold | grip an electric wire reliably.
