JP 2011-24371 A

  However, when these aggregates are connected, in the end portion of the aggregate, a small work is required to bend each column of each connecting member and insert the tip of each column into a small hole of the adjacent connecting member.

For this reason, workers wearing rubber gloves to prevent electric shock may not be able to connect well depending on the work environment.
Further, the conventional connecting member has a structure in which the support member of one connecting member is twisted, and the tip of the connecting member is put back into the hole of the other connecting member.

  Therefore, among the connecting members that are connected more than one, because some of them are affected by the wind and rotate around the electric wire, twisting occurs and the connection is broken, or the column has a shape that allows twisting, In some cases, the connecting members approach each other and become a dumpling.

  The present invention provides a connecting member, a drop-off preventing member, and a bird damage prevention device that can be easily connected even when an operator wears a rubber glove for preventing electric shock, and that prevents coming off from a twist. The purpose is to do.

The connecting member according to claim 1 is:
A body portion (30) formed in a frame shape forming an insertion hole for inserting an electric wire;
A plurality of needle-like parts (31) erected outward from the main body part;
A pedestal portion (32) which is erected outward from the main body portion and has a contact surface (32a) on one side in the axial direction of the insertion hole;
A strut portion erected from the pedestal portion, the strut portion erected along the axial direction from the other side of the axial direction of the insertion hole (33);
An attachment piece (34) having a tip surface (34a) that is provided at the tip of the support column and is in surface contact with the contact surface of the pedestal portion of the adjacent connecting member;
A protrusion (35) provided on the pedestal or the mounting piece,
A retaining hole portion (36) provided in the pedestal portion or the attachment piece portion;
With
As for the adjacent connecting members, when the protruding portion is inserted into the retaining hole portion, the protruding portion is retained from the retaining hole portion, and the contact surface of the pedestal portion and the mounting piece portion are retained in the retained state. It is characterized in that the tip surface of the abutment comes into contact.

  According to this, for example, when connecting adjacent connecting members through which an electric wire is passed through the insertion hole, the support member of one connecting member is sandwiched between the index finger and the middle finger, and the thumb is hooked on the base portion of the adjacent connecting member, When the index finger and the middle finger are brought close to the thumb (or vice versa), the attachment piece part of one connection member of the pair of connection members to be connected and the base part of the other connection member come close to each other, and the protrusion part of the base part is It hits the contact surface or the tip of the mounting piece.

When the finger sandwiching the support column is moved in this state, the tip of the projection moves on the contact surface or the tip surface, and eventually the tip of the projection falls to the retaining hole.
At this time, when the thumb that is in contact with the pedestal and the index finger and middle finger that are in contact with the mounting piece are pushed from both sides so that the pedestal and the mounting piece are close to each other, the protrusion is inserted into the retaining hole and is removed as it is. Further, the contact surface comes into contact with the tip surface.

Thus, the connection member of the present invention can be easily connected using three fingers when connecting adjacent connection members.
For this reason, the connecting member of the present invention can be easily connected even when an operator wears a rubber glove for preventing electric shock.

  In addition, since the pedestal portion and the mounting piece portion are in surface contact with each other after the connection member of the present invention is connected, a plurality of connection members are connected to form a bird damage prevention device. When it is moved by pushing it with a hand while being applied to it, the force of pushing the bird harm prevention tool can be smoothly transmitted to each connecting member. Therefore, the bird harm prevention tool moves smoothly along the electric wire while being hung on the electric wire.

  The shape of the insertion hole may be circular, elliptical, or other shapes. In addition, as described in claim 6, a pair of pedestal portions may be provided on both sides of the main body portion. For example, two or more pedestal portions are provided at equidistant positions at three locations around the main body portion. You may make it prepare.

Next, as in the connection member described in claim 2, the support column may be positioned closer to the center axis side of the insertion hole than the protrusion and the retaining hole.
If it does in this way, since a support | pillar part is located near the center part of a main-body part, connection members are stably joined, and a projection part and a retaining hole part can be located in a near side seeing from an operator. Therefore, it becomes easy to insert the protruding portion into the retaining hole portion.

For this reason, the connecting member of the present invention can easily connect the members even when the operator wears gloves, and can maintain a stable connected state after the connection.
Next, as in the connecting member according to claim 3, the pedestal portion or the attachment piece portion is provided with a displacement prevention portion (32c) for preventing the attachment piece portion contacting the pedestal portion from being displaced from the pedestal portion. You may make it prepare.

  When the projection is inserted into the retaining hole and the mounting piece and the pedestal are connected, there is a possibility that they will be displaced with the projection as a fulcrum, and the mounting piece and the pedestal will be in surface contact. However, by providing this misalignment prevention part, such misalignment and twist can be prevented.

  For this reason, when this misalignment prevention part is provided, the pedestal part and the mounting piece part can be brought into surface contact without reducing the area where they come into surface contact. And when this bird damage prevention tool is pushed and moved with the hand applied to the electric wire, the force pushing the bird damage prevention tool can be smoothly transmitted to each connecting member. Therefore, the bird harm prevention tool moves smoothly along the electric wire while being hung on the electric wire.

Next, like the connection member described in claim 4, ribs thicker than the main body may be provided at the edge of the insertion hole.
If it does in this way, since a main-body part intensity | strength increases with a rib, the thickness of a main-body part can also be made thinner than what is not equipped with the rib (30b).

  In addition, when the connecting member is attached to the electric wire, it comes into surface contact with the electric wire by the rib. Therefore, even if the connecting member is pushed in the longitudinal direction of the electric wire while being attached to the electric wire, the sleeve cover, the drainage cover, etc. can be smoothly moved. Get over. Therefore, even if a bird damage prevention tool is constituted by connecting a plurality of connecting members and the bird damage prevention tool is pushed and moved by hand while being applied to an electric wire, the bird damage prevention tool can be moved smoothly.

  Next, as in the connecting member described in claim 5, when a cut (30d) for inserting an electric wire into the insertion hole is formed in the main body portion, the cut is located outside the insertion hole. It is preferable that the electric wires are provided inclined with respect to the direction toward the center of the insertion hole.

  In this way, when inserting the electric wire into the insertion hole, if the electric wire is applied to the main body portion where the cut is provided and pressed toward the main body portion, the electric wire enters the cut and follows the cut. Move diagonally and enter the insertion hole. As described above, when the electric wire enters the insertion hole, the notch is inclined, so that the electric wire is difficult to be removed from the insertion hole. Therefore, this connecting member can be easily and reliably attached to the electric wire.

This notch is provided with a pair of wide needle-like parts (31a) wider than the other needle-like parts in the main body part to serve as a weight, and a gap between the wide needle-like parts is provided at the starting point. May be.
Moreover, it is good to provide this notch | incision so that the edge part of the notch provided in the insertion hole may not come directly under an electric wire, when passing an electric wire through an insertion hole. This is because if the notch is directly underneath, the possibility of falling off and coming off easily from the electric wire increases. In this case, when the bird damage prevention device in which a plurality of connecting members are connected is arranged on the electric wire so that the notch is arranged at a position facing the electric wire and pushed downward from above, it is obliquely deformed in the connected state. It is inserted with slipping.

Next, like the connection member described in claim 8, the following drop-off preventing member may be connected to the connection member.
The drop-off prevention member includes a main body portion (50), a needle-like portion (51), a pedestal portion (50), a support post portion (53), a mounting piece portion (54), a protruding portion (55), and a retaining portion. The main body portion is provided with a recess portion (50a) in which an electric wire is arranged instead of the insertion hole, and the pedestal portion is on both sides of the opening portion of the recess portion. Is different from the connecting member in that it is provided on both sides of the main body and is provided so as to be erected from the main body.

This drop-off preventing member is used by being connected to a connecting member having a notch described in claim 5.
Specifically, after placing the connecting member so that the notch is positioned downward, it is pushed into the electric wire from above, and the drop prevention member is inserted upward from below so that the electric wire enters the recess, These connecting members and drop-off preventing members are connected and attached to the electric wire.

  In this case, when the connecting member is detached from the electric wire, it is pulled upward and the electric wire comes out of the notch and comes off. Can be prevented from coming off the electric wire.

  In addition, as described in claim 7, a bird damage prevention tool may be configured by connecting a plurality of the connecting members according to any one of claims 1 to 6, or as described in claim 9. Moreover, you may comprise a bird damage prevention tool by connecting the some connection member of any one of Claims 1-6, and the at least 1 drop-off prevention member described in Claim 8.

As shown in FIG. 1, the bird harm prevention tool 1 of the present embodiment is used by being attached to an electric wire, and is configured by connecting a plurality of connecting members 3, and at least one drop-off preventing member 5. Are connected.
<Connecting member 3>
As shown in FIGS. 2 and 3, the connecting member 3 includes a main body portion 30, a needle-like portion 31, a pedestal portion 32, a support column portion 33, a mounting piece portion 34, and a protruding portion 35. .

  The main body 30 is formed in a ring shape, and forms an insertion hole 30a through which the electric wire is inserted. A rib 30b that is thicker in the axial direction of the insertion hole 30a than other portions is provided at the edge of the insertion hole 30a.

  The needle-like part 31 is formed to have the same thickness as the part other than the rib 30 b of the main body part 30, and from the outer peripheral edge part of the main body part 30 along the same plane as the main body part 30. A plurality of erections are provided radially outward from the center.

  Of these needle-like portions 31, two adjacent needle-like portions that are positioned below when the connecting member 3 is attached to the electric wire are formed wider than the other needle-like portions. . These wide needle-like portions are hereinafter referred to as wide needle-like portions 31a in order to distinguish them from other needle-like portions 31.

The main body 30 is formed with a cut 30d for inserting an electric wire from the crotch portion of the wide needle-like portion 31a into the insertion hole 30a.
This notch 30d is provided so as to be inclined with respect to the direction in which the electric wire located outside the insertion hole 30a is directed toward the center of the insertion hole 30a (the direction from the lower side to the upper side in FIG. 3A).

  A pair of pedestal portions 32 are provided, each formed in a long plate shape. When the connecting member 3 is attached to the electric wire so that the wide needle-like portion 31a is positioned below, these pedestal portions 32 are in the height direction of the main body portion 30 (in the direction from the bottom to the top in FIG. 3A). From the outer peripheral edge near the intermediate height position, it is erected in the left-right direction along the same plane as the main body 30.

  The pedestal portions 32 pass through the center in the width direction (the vertical direction in FIG. 3A), and the center line along the longitudinal direction is positioned below the center point of the body portion 30. Is provided against. Further, the pedestal 32 is provided such that when the connecting member 3 is attached to the electric wire, the center line in the center in the width direction is positioned below the central axis of the electric wire as shown in FIG. ing.

Note that one of the two surfaces perpendicular to the axial direction of the insertion hole 30a on the surface of the pedestal portion 32 is referred to as an abutment surface 32a. A surface on the back side of the contact surface is referred to as a contact back surface 32b.
As shown in FIG. 3A, each contact surface 32 a is on the contact surface 32 a when the connecting member 3 is viewed from the side where the support column portion 33 is erected. Above and below the installation position, a pair of protrusion-shaped deviation preventing portions 32c are provided.

  These misalignment prevention portions 32c abut attachment portions 34, which will be described later, of the other connecting members 3 so that projecting portions 35, which will be described later, of the other connecting members 3 enter the retaining holes 36 (see FIG. 2), which will be described later. It is provided at a position where it comes into contact with the upper and lower edges of the mounting piece 34 when it is brought into contact with the surface 32a.

As shown in FIGS. 2 and 3, the support column 33 is erected along the axial direction of the insertion hole 30 a from the contact back surface 32 b of each pedestal unit 32.
The column portion 33 is provided on the contact surface 32a on the inner axis side of the pedestal portion 32, which is closer to the main body portion 30, that is, on the center axis side of the insertion hole 30a than the projection portion 35 and the retaining hole portion 36. It is erected along a straight line passing through the center position of the shift prevention portion 32c.

  The attachment piece 34 is a plate-like member provided at the tip of each support column 33, and is attached perpendicularly to each support column 33, and is paired as viewed from the attachment position to each support column 33. It is extended toward the opposite side to the side which goes to the attaching piece part 34 which becomes.

In this attachment piece 34, a side 342 opposite to the side 341 on the side facing the paired attachment piece 34 is formed in a semicircular shape having a larger diameter than the side 341 on the opposite side.
And the protrusion part 35 is standingly arranged from the front end surface 34a which is a surface on the opposite side to the surface where the support | pillar part 33 is attached among this attachment piece part 34. As shown in FIG.

  The projection 35 is erected around the center of the side 342 of the mounting piece 34 and has a shape like an arrow when viewed from the side, and has a conical tip 351 on the base 352. It is formed in the shape which has.

  Looking again at the pedestal portion 32, the side of the pedestal portion 32 on the outer side (opposite to the side closer to the main body portion 30) is formed in a semicircular shape. A retaining hole portion 36 into which the protruding portion 35 is inserted is formed.

  The retaining hole 36 is formed at a position where the protrusion 35 of the pedestal 32 can be inserted when the attachment piece 34 is brought close to the contact surface 32a of the pedestal 32 so as to connect the adjacent connecting members 3. ing.

  As shown in FIG. 3 (d), the retaining hole portion 36 has a recessed portion on the side of the peripheral edge portion 36 a (a portion having a constant width from the edge of the retaining hole portion 36) that is in contact with the protruding portion 35. It is formed in a shape that becomes thinner toward the center.

  Therefore, when the projection 35 is inserted into the retaining hole 36, the tip 351 hits the retaining hole 36 and proceeds while bending the peripheral edge 36 a of the retaining hole 36. And if the front-end | tip part 351 passes, the peripheral part 36a of the retaining hole part 36 will return to the original shape, and will catch the front-end | tip part 351, and will prevent removal.

At this time, the contact surface 32a of the pedestal portion 32 of the adjacent connecting member 3 and the distal end surface 34a of the attachment piece 34 come into contact with each other, and the inner wall surface of the displacement prevention portion 32c is on the small diameter side of the attachment piece 34. Since the sides abut and both ends of the shift prevention portion 32c are formed in a small amount and straight, the attachment piece portion 34 is fixed to the pedestal portion 32.
<Characteristic effects of the connecting member 3 of this embodiment>
The connecting member 3 configured as described above, for example, when connecting adjacent connecting members 3 through which electric wires are passed through the insertion holes 30a, sandwiches the support 33 of one connecting member 3 between the index finger and the middle finger, When a thumb is hooked on the pedestal 32 of the adjacent connecting member 3 and the index and middle fingers are brought close to the thumb (or vice versa), the attachment piece 34 and the other of the connecting member 3 of the pair of connecting members 3 to be connected The pedestal 32 of the connecting member 3 approaches each other, and the protrusion 35 abuts against the contact surface 32 a of the pedestal 32.

When the finger sandwiching the support column 33 is moved in this state, the tip of the projection 35 moves on the contact surface 32a, and the tip of the projection 35 eventually falls into the retaining hole 36.
Therefore, when the thumb that is in contact with the pedestal 32 and the index finger and middle finger that are in contact with the attachment piece 34 are pushed from both sides so that the pedestal 32 and the attachment piece 34 are close to each other, the projection 35 is retained in the retaining hole 36. The contact surface 32a contacts the tip end surface 34a.

Thus, the connection member 3 of this embodiment can be easily connected using three fingers of one hand.
Therefore, even if each connecting member 3 of this embodiment is small, an operator can attach rubber gloves and can connect each member well.

The connection method may be other than the method using three fingers, and the above is only an example.
Moreover, the connection member 3 of this embodiment is provided with the support | pillar part 33 inside, and the projection part 35 and the retaining hole part 36 outside.

  In this case, since the support column 33 is positioned closer to the center of the main body 30, when the connecting member 3 is connected, these are stably connected, and the protrusion 35 and the retaining hole 36 are provided to the operator. Therefore, the protrusion 35 can be easily inserted into the retaining hole 36.

Therefore, the connection member 3 of this embodiment can connect each connection member 3 well, even if the worker wears rubber gloves, and can maintain a stable connection state after connection.
Moreover, since the base part 32 and the attachment piece part 34 surface-contact after the connection member 3 of this embodiment is connected, the some damage prevention tool 1 is comprised by connecting the some connection member 3, and this When the bird harm prevention tool 1 is pushed and moved by hand while being applied to the electric wire, the force pushing the bird harm prevention tool 1 can be smoothly transmitted to each connecting member 3. Therefore, the bird harm prevention tool 1 moves smoothly along the electric wire while being attached to the electric wire.

  In addition, since the connecting member 3 according to the present embodiment is provided with the misalignment prevention portion 32c, the attachment piece portion 34 and the pedestal portion 32 are less likely to be misaligned with respect to the protruding portion 35 inserted into the retaining hole portion 36. The piece 34 is fixed to the pedestal 32.

For this reason, when the shift preventing portion 32c is provided, the adjacent connecting members 3 are stably fixed.
Further, in the connecting member 3 of the present embodiment, the main body portion 30 includes a rib 30b, and the strength of the main body portion 30 is increased by the rib 30b. Therefore, the thickness of the main body portion 30 (part other than the rib 30b) is set to the rib. It can also be made thinner than those not provided with 30b.

  Further, since the connecting member 3 comes into surface contact with the electric wire by the rib 30b when attached to the electric wire, even if the connecting member 3 is pushed and moved in the longitudinal direction of the electric wire while being attached to the electric wire, a sleeve cover, a drain cover, etc. Get through smoothly. Therefore, even if the bird damage prevention tool 1 is constituted by connecting a plurality of connecting members 3 and the bird damage prevention tool 1 is pushed and moved by hand while being applied to the electric wire, the bird damage prevention tool 1 is moved smoothly. be able to.

Further, the connecting member 3 of the present embodiment is provided with an inclined cut 30 d in the main body 30.
The connecting member 3 of the present embodiment is provided with the notches 30d, so that when the electric wires are inserted into the insertion holes 30a, the connecting members 3 are directed toward the main body portion 30 by applying the electric wires to the main body portion 30 where the cuts 30d are provided. Just press it.

If it does in this way, it is because an electric wire enters into the notch 30d, moves diagonally along this notch 30d, and enters into the insertion hole 30a.
In addition, when the notch 30d is provided, after the electric wire enters the insertion hole 30a, the notch 30d is inclined, and the inclination direction is different from the direction in which the electric wire is about to come out. It becomes difficult for the electric wire to come out of the insertion hole 30a.

Therefore, the connecting member 3 can be easily and reliably attached to the electric wire.
<Falling prevention member 5>
Next, the dropout prevention member 5 will be described.

As for the drop-off preventing member 5, only the configuration different from the connecting member 3 described above will be described.
As shown in FIGS. 4 and 5, the drop-off preventing member 5 includes a main body base portion 50, a needle-like portion 51, a support portion 53, an attachment piece portion 54, a projection portion 55, and a retaining hole portion 56. Have

  Among these, for the column part 53, the mounting piece part 54, the projection part 55, the retaining hole part 56, and the displacement preventing part 50d, the column part 33, the mounting piece part 34, the projecting part 35, the retaining hole part 36 of the connecting member 3, Since the configuration is the same as that of the misalignment prevention unit 32c, description thereof is omitted.

The main body pedestal 50 has a configuration corresponding to the main body 30 and the pedestal 32 of the connecting member 3.
As for the connecting member 3, since the vertical width of the pedestal portion 32 is smaller than that of the main body portion 30, these are distinguished and called, but the drop-off prevention member 5 has no big difference between them, so call them all together. Yes.

  In this drop-off prevention member 5, a recess 50 a in which an electric wire is arranged is provided instead of the insertion hole 30 a, but the portion provided with this recess 50 a may be called a main body. And the part provided with the support | pillar part 53 and the retaining hole part 56 may be called a base part. In addition, the rib 50c is provided in this recessed part 50a similarly to the connection member 3. FIG.

In this case, the pedestal portion is provided on both sides of the opening 50b of the recess 50a and on both sides of the body portion, and corresponds to a portion standing from the body portion.
Next, two needle-like portions 51 of the drop-off preventing member 5 are provided, unlike the needle-like portions 31 of the connecting member 3, and each needle-like portion 51 extends upward from both ends of the recess 50a. ing.

As shown in FIG. 1, the drop-off prevention member 5 is connected one by one every time a certain number of connection members 3 are connected when the bird damage prevention tool 1 is configured.
In this case, the connecting member 3 is arranged so that the notch 30d is positioned downward, and then pushed into the electric wire from above, and the drop-off prevention member 5 is directed upward from below so that the electric wire enters the recess 50a. The connecting member 3 and the drop-off preventing member 5 are connected and attached to the electric wire.

In this case, when the connecting member is detached from the electric wire, it is pulled upward and the electric wire comes out of the notch and comes off. Can be prevented from coming off the electric wire.
<Characteristic effects of the drop-off prevention member 5 of this embodiment>
If it does in this way, when connecting member 3 comes off from an electric wire, it will come off from the side in which cut 30d was provided, but even if connecting member 3 comes off like this, since an electric wire is caught in crevice 50a of drop-off prevention member 5, It is possible to prevent the bird damage prevention tool 1 from being detached from the electric wire.
