Description

[Technical field]

[0001] The present disclosure relates to a wire end cover that is attached to the end of an electric wire. [Background technology]

[0002] The ends of high-voltage insulated electric wires are protected by covering them with electric wire end covers to ensure electrical insulation. As one such technique, for example, Patent Document 1 discloses an electric wire end cover that can be attached by inserting it through an opening. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2003-143745 A Summary of the Invention [Problem to be solved by the invention]

[0004] The wire end cover is intended to prevent short circuits, leakage current due to ground faults, electric shock, etc. Therefore, it is highly desirable that the inserted wires are securely fixed to the wire end cover. An object of the present disclosure is to propose a wire end cover that can effectively prevent the wire from falling off. [Means for solving the problem]

[0005] One aspect of the present disclosure is an electric wire end cover that covers an end of an electric wire, and includes a cover body and a moving part. The cover body has an insertion hole. The moving part is disposed inside the insertion hole. When an electric wire is inserted from an opening of the insertion hole, the moving part is pushed by the electric wire and moves from the opening toward the back of the insertion hole. The moving part also includes at least one pressing part. The at least one pressing part is configured to move toward a side surface of the electric wire and press the electric wire as the moving part moves toward the back of the insertion hole. When the moving part moves to a predetermined locking position of the insertion hole, a first locking part provided on the cover body and a second locking part provided on the moving part are locked to prevent the moving part from coming out of the insertion hole.

[0006] With this configuration, when an electric wire is inserted into the opening of the insertion hole and the moving part is pushed deep into the insertion hole, the pressing part presses the side of the electric wire. As a result, for example, friction between the pressing part and the electric wire or the pressing part bites into the electric wire occurs, and the electric wire is fixed to the pressing part. When the moving part is pushed by the electric wire and moves to a predetermined locking position, the first locking part and the second locking part are locked to each other, preventing the electric wire from falling off the insertion hole. Therefore, the state in which the electric wire is fixed to the pressing part is maintained, and the electric wire end cover can be effectively prevented from falling off the electric wire.

[0007] In the above-mentioned electric wire end cover, the at least one pressing portion may include at least two pressing portions. The at least two pressing portions may move to pinch the electric wire as the moving portion moves toward the back of the insertion hole. With this configuration, the electric wire can be pinched and fixed by the at least two pressing portions.

[0008] In the above-mentioned electric wire end cover, at least one pressing portion may include a first portion and a second portion, and when the moving portion is inserted to a predetermined position in the insertion hole, the first portion may move to a position closer to a central axis of the electric wire inserted into the insertion hole than the second portion.

[0009] In this configuration, the first and second parts can press and fix electric wires of different diameters. The first part can fix an electric wire of a relatively small diameter, and the second part can fix an electric wire of a relatively large diameter. Therefore, the above-mentioned electric wire end cover can be appropriately attached to the ends of electric wires of different diameters.

[0010] In the above-mentioned electric wire end cover, the pressing portion may have a contact surface that faces the opening side from the back of the insertion hole and that contacts the electric wire and receives a load from the electric wire toward the back of the insertion hole when the electric wire is inserted into the insertion hole. With this configuration, the load from the electric wire can be appropriately received by the contact surface, and the moving portion can be smoothly moved toward the back of the insertion hole.

[0011] In the above-mentioned electric wire end cover, the pressing portion may have a protrusion protruding toward the electric wire. With such a configuration, the protrusion can bite into a side surface of the electric wire, so that the electric wire can be more firmly fixed to the pressing portion, and the electric wire end cover can be more effectively prevented from falling off from the electric wire.

[0012] In the above-mentioned wire terminal cover, when the moving part is located at a secondary locking position, which is a position closer to the opening of the insertion hole than the above-mentioned locking position, a first secondary locking portion provided on the cover body and a second secondary locking portion provided on the moving part may be configured to engage with each other to prevent the moving part from slipping out of the insertion hole.

[0013] With this configuration, when the moving part is in the secondary locking position, the moving part is located closer to the opening than when the moving part is in the locking position. Therefore, when the moving part is in the secondary locking position, the amount of movement of the pressing part toward the side of the electric wire is small, making it easier to insert the electric wire. With the above configuration, the first secondary locking part and the second secondary locking part are locked together, so that the electric wire can be maintained in a state where it is easy to insert, thereby simplifying the task of attaching the electric wire end cover to the electric wire.

[0015] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. [1. Embodiment] [1-1. Configuration of wire terminal cover] FIG. 1 shows an electric wire end cover 1 of this embodiment. The electric wire end cover 1 is attached to an end of an electric wire 3 to cover the end of the electric wire 3 and suppress leakage of electricity from the end of the electric wire 3. The electric wire end cover 1 is formed of an insulating material such as synthetic resin. The electric wire 3 here refers to an electric wire covered with an insulator, and includes a high-voltage insulated electric wire that is hung on a utility pole. The electric wire end cover 1 has a cover body 10 and a moving part 20.

[0016] 2A-2D and 3 show the cover body 10. The cover body 10 has an approximately conical outer shape and has an insertion hole 11 extending in the height direction. As shown in Figs. 2C, 2D and 3, the insertion hole 11 is a through hole penetrating the cover body 10. The opening 12a at the bottom of the cone is wider than the tip opening 12b at the tip of the cone. In the following description, the side where the opening 12a is formed is defined as the lower side, and the side where the tip opening 12b is formed is defined as the upper side, and the description will be given using the up-down direction. The directions perpendicular to the up-down direction are defined as the front-rear and left-right directions. These directions are used merely for convenience of description and do not limit the manner of use of the electric wire terminal cover 1.

[0017] The insertion hole 11 includes an insertion space 11a, which is a space into which an electric wire is mainly inserted, and a pair of left and right insertion grooves 11b, which are grooves into which the moving part 20 is mainly disposed. The insertion space 11a is a substantially cylindrical space, and as shown in FIG. 3, has a portion in the vertical center that narrows toward the upper side. The pair of insertion grooves 11b are portions recessed toward the outside on the inner wall surface of the insertion hole 11, and extend vertically. The pair of insertion grooves 11b are located on opposite sides facing each other with the insertion space 11a as the center. The distance between the pair of insertion grooves 11b narrows toward the upper side.

[0018] A locking hole 13, which is a through hole, is formed near the lower end of the cover body 10. The locking hole 13 is formed at a position where the pair of insertion grooves 11b are formed. The locking hole 13 corresponds to a first locking portion and a first sub-locking portion.

[0019] A first flange portion 14 that spreads outward from the periphery is formed at the bottom end of the cover body 10. A second flange portion 15 that spreads outward from the periphery is formed at approximately the center of the cover body 10 in the vertical direction. The first flange portion 14 and the second flange portion 15 function as anti-slip when the cover body 10 is grasped by hand or with a tool. A pair of protrusions 16 that extend up and down are formed from the bottom end to the top of the cover body 10. The protrusions 16 are portions that protrude in accordance with the insertion groove 11b, and one is formed on each side.

[0020] 4A-4C show the moving part 20. Also, FIGS. 5A-5C show the moving part 20 inserted into the cover body 10. The moving part 20 is disposed inside the insertion hole 11. The moving part 20 has two pressing parts 21 and a connecting part 22 that connects the two pressing parts 21. The pressing part 21 is a rod-shaped member that has a length in the vertical direction. The connecting part 22 connects the upper ends of the two pressing parts 21 together. The connecting part 22 is formed thinner than the pressing parts 21, and the two pressing parts 21 can approach and separate from each other by elastically deforming the connecting part 22.

[0021] 5A, the two pressing portions 21 are disposed in the pair of insertion grooves 11b, respectively. In other words, the two pressing portions 21 are disposed at positions opposite to each other with respect to the electric wire 3 inserted into the insertion hole 11 as the center.

[0022] 4A-4C, the pressing portion 21 has a second locking portion 23, a second sub-locking portion 24a and a second sub-locking portion 24b, a first contact surface 25, a second contact surface 26, a third contact surface 27, and a plurality of protrusions 28. In the following description, when the second sub-locking portion 24a and the second sub-locking portion 24b are not to be distinguished from each other, they will be simply referred to as the second sub-locking portion 24.

[0023] The second locking portion 23 is a protrusion provided at the lower end of the pressing portion 21 and protruding outward in the left-right direction. As shown in Figs. 5C and 6, when the moving portion 20 moves to the locking position, the second locking portion 23 enters the locking hole 13. This prevents the moving portion 20 from coming out of the insertion hole 11. The locking position in this embodiment is the position when the moving portion 20 is inserted to the deepest extent into the insertion hole 11. In the following description, the state in which the moving portion 20 is in the locking position is also referred to as the locked state.

[0024] The explanation will be returned to Figs. 4A-4C. The second sub-locking portion 24 is formed at a position above the second locking portion 23 in the pressing portion 21. The second sub-locking portion 24a is disposed relatively on the upper side and the front side, and the second sub-locking portion 24b is disposed relatively on the lower side and the rear side. As shown in Figs. 1 and 5B, when the moving portion 20 is inserted to the sub-locking position, the second sub-locking portion 24 engages with the locking hole 13, preventing the moving portion 20 from coming out of the insertion hole 11. The sub-locking position is a position closer to the opening 12a of the insertion hole 11 than the locking position. The second sub-locking portion 24a and the second sub-locking portion 24b are protrusions that protrude slightly forward and backward. Therefore, the second sub-locking portion 24a and the second sub-locking portion 24b are more likely to be disengaged from the locking hole 13 than when the second locking portion 23 is inserted into the locking hole 13 and engaged therewith. In the following description, the state in which the moving part 20 is in the secondary locking position will also be referred to as the secondary locking state.

[0025] The first contact surface 25, the second contact surface 26, and the third contact surface 27 are formed on the surfaces of the two pressing parts 21 facing each other. These contact surfaces face the opening 12a from the back of the insertion hole 11, in other words, face downward. Here, downward also includes the diagonally downward direction. The first contact surface 25 is provided at a position near the upper end of the pressing part 21 and spreads in the horizontal direction. The second contact surface 26 is a surface provided below the first contact surface 25 and is an inclined surface that slopes inward toward the upper side. The third contact surface 27 is a surface provided below the second contact surface 26 and is an inclined surface that slopes inward toward the upper side. When the electric wire 3 is inserted into the insertion hole 11, these contact surfaces come into contact with the electric wire 3 and receive a load from the electric wire 3 toward the back of the insertion hole 11.

[0026] The first portion 21a is a portion of the pressing portion 21 from the height where the first contact surface 25 is formed to the height where the second contact surface 26 is formed. The second portion 21b is a portion of the pressing portion 21 from the height where the second contact surface 26 is formed to the height where the third contact surface 27 is formed. The third portion 21c is a portion of the pressing portion 21 from the lower end of the moving portion 20 to the height where the third contact surface 27 is formed.

[0027] 5C, when the moving portion 20 is inserted to the locked position, the first portion 21a moves to a position closer to the axis A, which is the center of the electric wire inserted into the insertion hole 11, compared to the second portion 21b. Also, the second portion 21b moves to a position closer to the axis A, compared to the third portion 21c. Thus, in the locked state, if the distance between the first portions 21a of the two pressing portions 21 is L1, the distance between the second portions 21b is L2, and the distance between the third portions 21c is L3, then L1 <L2<L3となる。

[0028] The left-right width of the lower end portion of the moving part 20 when no load is applied (L4 in FIG. 5A) is greater than the left-right width of the lower end of the insertion hole 11 including the insertion groove 11b (L5 in FIG. 5C). Therefore, as the moving part 20 moves deeper into the insertion hole 11, the pressing part 21 approaches the axis A side.

[0029] The protrusions 28 protrude toward the electric wire. As shown in Fig. 4A and 4B, the protrusions 28 are provided at three locations on both the left and right pressing portions 21 for the first portion 21a. Meanwhile, the protrusions 28 are provided at two locations on the left pressing portion 21 for the second portion 21b and the third portion 21c, but are provided at only one location on the electric wire end cover for the right pressing portion 21. Furthermore, the protrusions 28 are arranged at staggered positions on the left and right pressing portions 21 so as not to face each other.

[0030] [1-2. Operation of the wire terminal cover] Before inserting the electric wire 3 into the electric wire end cover 1, the cover body 10 and the moving part 20 are assembled. As shown in FIG. 5A, the moving part 20 is inserted from the upper end (i.e., the connecting part 22 side) into the insertion hole 11 through the opening 12a. At this time, the pair of pressing parts 21 are inserted so as to fit into the pair of insertion grooves 11b. As shown in FIG. 5B, when the moving part 20 is inserted to the secondary locking position, the second secondary locking part 24 is locked into the locking hole 13. This loosely fixes the position of the moving part 20 relative to the cover body 10. The moving part 20 in the secondary locking position can be relatively easily released from the locked state and moved by applying force. In addition, the pair of pressing parts 21 of the moving part 20 in the secondary locking position are slightly closer to each other than in a natural state where no external load is applied.

[0031] When the electric wire end cover 1 is in the secondary locking state, the electric wire 3 can be inserted and attached. As described above, when the electric wire end cover 1 is in the secondary locking state (FIG. 5B), the amount of movement of the pressing portion 21 toward the side surface of the electric wire 3, in other words, the amount of movement toward the axis A, is smaller than when the electric wire end cover 1 is in the locked state (FIG. 5C). When the electric wire end cover 1 is in the secondary locking state, the distance between the pressing portions 21 is narrow and the electric wire 3 cannot be inserted, so the electric wire 3 is inserted when the electric wire end cover 1 is in the secondary locking state.

[0032] In the secondary locking state, similarly to the locked state, the intervals between the first portions 21a, between the second portions 21b, and between the third portions 21c are different from each other, that is, the diameters of the wires that can be inserted are different.

[0033] The electric wires 3a-3c shown in Figs. 7A-7C have different diameters, with the electric wire 3a being the thinnest and the electric wire 3c being the thickest. When the moving part 20 is in the secondary locking position, if the electric wire 3a is inserted upward from the opening 12a, the electric wire 3a is inserted until it abuts against the first abutment surface 25 (Fig. 7A). The electric wire 3b is inserted until it abuts against the second abutment surface 26 (Fig. 7B). The electric wire 3c is inserted until it abuts against the third abutment surface 27 (Fig. 7C). The electric wire 3b cannot be inserted deeper than the second abutment surface 26 due to its thickness, and the electric wire 3c cannot be inserted deeper than the third abutment surface 27 due to its thickness. In the following description, when the electric wires 3a-3c are not particularly distinguished from each other, they are referred to as electric wires 3.

[0034] When the electric wire 3 is further pushed upward in a state where the electric wire 3 is in contact with any of the contact surfaces, any of the contact surfaces receives a load from the electric wire 3 toward the back of the insertion hole 11. As a result, the moving part 20 is pressed into the electric wire 3 and moves from the opening 12a toward the back of the insertion hole 11. The two pressing parts 21 move toward the back along the insertion groove 11b, but since the two insertion grooves 11b are formed so as to approach each other toward the back, the two pressing parts 21 also approach each other as they move toward the back. As a result, the pressing parts 21 move toward the side of the electric wire 3 and press the electric wire 3. In other words, the two pressing parts 21 sandwich the electric wire 3 as the moving part 20 moves toward the back of the insertion hole 11. As shown in Figs. 8A-8C, the electric wire 3 fits into a portion spaced apart according to its thickness, is sandwiched between the pair of pressing parts 21, and is firmly fixed by the protrusions 28.

[0035] As described above, when the moving part 20 is inserted to the locking position, the locking hole 13 and the second locking part 23 are locked, and the falling off of the moving part 20 is effectively prevented. In other words, the locking hole 13 and the second locking part 23 form the falling off prevention part 30 that prevents the moving part 20 from falling off the insertion hole 11.

[0036] [1-3. Effects] According to the embodiment described above in detail, the following effects can be obtained. (1a) In the electric wire end cover 1 of this embodiment, when the electric wire 3 is inserted into the opening 12a of the insertion hole 11 and the moving part 20 is moved to a predetermined locking position, the electric wire 3 is fixed by the pressing part 21 and the moving part 20 (i.e., the pressing part 21) is prevented from falling off from the insertion hole 11. Therefore, the electric wire end cover 1 can be effectively prevented from falling off from the electric wire 3.

[0037] (1b) The two pressing parts 21 of the electric wire end cover 1 are disposed at positions opposite to each other with respect to the electric wire 3 inserted into the insertion hole 11, and move so as to pinch the electric wire 3 as the moving part 20 moves toward the back of the insertion hole 11. Therefore, the electric wire 3 can be pinched and fixed by these two pressing parts 21.

[0038] (1c) The pressing parts 21 each have a first part 21a, a second part 21b, and a third part 21c. The respective parts have different distances to the axis A when the moving part 20 is inserted to the locking position. Therefore, the first part 21a, the second part 21b, and the third part 21c are suitable for clamping the electric wire 3a, the electric wire 3b, and the electric wire 3c, respectively, as shown in Figs. 8A-8C. Therefore, the electric wire end cover 1 can be appropriately attached to the ends of the electric wires 3a-3c having different diameters.

[0039] (1d) The pressing portion 21 has a first abutment surface 25, a second abutment surface 26, and a third abutment surface 27 which are surfaces facing the opening 12a from the depth of the insertion hole 11 and which abut against the electric wire 3 when the electric wire 3 is inserted into the insertion hole 11 and receive a load from the electric wire 3 toward the depth of the insertion hole 11. Therefore, the load from the electric wire 3 can be appropriately received at each abutment surface, and the moving portion 20 can be smoothly moved toward the depth of the insertion hole 11.

[0040] Furthermore, when the moving part 20 is in the secondary locking position, the distance between the first contact surfaces 25 of the two pressing parts 21, the distance between the second contact surfaces 26, and the distance between the third contact surfaces 27 are all different. Therefore, when the ends of the electric wires 3a-3c are inserted through the opening 12a, they come into contact with the contact surfaces according to their diameters, and the moving part 20 is pushed inward from there. That is, even if electric wires 3 with different diameters are inserted, the moving part 20 can be moved.

[0041] (1e) The pressing portion 21 has a plurality of protrusions 28 protruding toward the electric wire 3. Therefore, the protrusions 28 bite into the side surfaces of the electric wire 3, so that the electric wire 3 can be more firmly fixed to the pressing portion 21, and the electric wire end cover 1 can be more effectively prevented from falling off from the electric wire 3.

[0042] (1f) When the electric wire end cover 1 is in the secondary locking state, the pressing portions 21 are spaced apart from each other more than when it is in the locked state, so that the electric wire 3 can be easily inserted. Therefore, the work of attaching the electric wire 3 can be simplified.

[0043] [2. Other embodiments] Although the embodiments of the present disclosure have been described above, it goes without saying that the present disclosure is in no way limited to the above-described embodiments, and can take various forms as long as it falls within the technical scope of the present disclosure.

[0044] (2a) In the above embodiment, the moving part 20 is illustrated as having two pressing parts 21. However, the number of pressing parts provided in the moving part is not limited to two. For example, the moving part may have only one pressing part, and may be configured to pinch the electric wire 3 between the pressing part and the inner wall of the insertion hole. Also, for example, the moving part may have three or more pressing parts.

[0045] (2b) In the above embodiment, a configuration has been exemplified in which the moving part 20 is locked to the cover body 10 when the moving part 20 is deeply inserted into the insertion hole 11 of the cover body 10. Specifically, a configuration has been exemplified in which the moving part 20 is locked when it is located at either the locking position or the secondary locking position. However, a configuration may also be used in which the moving part 20 is not locked at the secondary locking position, i.e., the secondary locking position does not exist.

[0046] Also, in the illustrated configuration, the locking hole 13 and the second locking portion 23 are locked together in the locking position, and the locking hole 13 and the second sub-locking portion 24 are locked together in the sub-locking position. That is, the illustrated configuration has the locking hole 13 functioning as both a first locking portion that locks with the second locking portion 23, and a first sub-locking portion that locks with the second sub-locking portion 24. However, the first sub-locking portion that locks with the second sub-locking portion 24 may be a portion separate from the locking hole 13.

[0047] (2c) In the above embodiment, the pressing portion 21 has three parts, the first part 21a, the second part 21b, and the third part 21c, which can clamp and fix the electric wires 3 having different diameters. However, the pressing portion 21 may have only one or two of the three parts. Also, the pressing portion 21 may have four or more parts, i.e., four or more types of electric wires having different diameters, which can be properly fixed. The shape of the surface of the pressing portion facing the electric wire is not particularly limited as long as it can hold down the electric wire.

[0048] (2d) In the above embodiment, the pressing portion 21 has a contact surface including the first contact surface 25, which faces downward, and the second and third contact surfaces 26 and 27, which face downward and are inclined inwardly toward the upper side. However, the shape of the contact surface is not limited to this. For example, the contact surface may be a wall portion that protrudes inward from the inner wall surface of the insertion hole 11.

[0049] (2e) In the above embodiment, a configuration in which a plurality of protrusions 28 are formed on the pressing portion 21 is exemplified. The number, arrangement, and shape of the protrusions 28 are not limited to the configuration disclosed in the embodiment. In addition, the protrusions 28 may not be provided.

[0050] (2f) The wire end cover 1 disclosed in the above embodiment can be modified into various shapes. For example, the external shape of the cover body 10, the shape of the inner wall surface constituting the insertion hole 11, and the shape of the moving part 20 can be modified into various shapes within a range in which the intended function can be realized. For example, in the cover body 10, the insertion hole 11 does not have to be a through hole. Furthermore, when the moving part 20 has multiple pressing parts 21, it may not have a connecting part 22 and may be configured to move separately within the insertion hole 11.

[0051] Also, for example, as in the electric wire terminal cover 101 shown in Figs. 9A-9C, the cover body 110 may include a guard 111 that covers the pressing portion 21 of the moving portion 20. The guard 111 covers three faces, other than the inner face, of the moving portion 20 in the secondary locking state, at a portion that protrudes downward from the first flange portion 14. The inner face here refers to the face where the two moving portions 20 face each other. Also, the guard 111 extends to a position lower than the lower end of the moving portion 20 in the secondary locking state. With this configuration, it is possible to prevent the moving portion 20 in the secondary locking state from coming into contact with something other than the electric wire 3 (for example, a hand or a tool), and as a result, it is possible to prevent the moving portion 20 from being erroneously pushed into the cover body 110. The shape of the guard 111 is not particularly limited. For example, the guard 111 may have a shape that covers the inner face of the moving portion 20, or may not cover any one or more faces of the three faces other than the inner face. Also, it is not necessary for the guard 111 to extend to a position lower than the lower end of the moving portion 20. In other words, the guard 111 may have any shape as long as it prevents the moving part 20 from being accidentally pushed in by a hand or the like.

[0052] 10, the cover body 210 may include guards 211 and a cylindrical connecting plate 212 connecting two guards 211. The guards 211 have the same shape as the guards 111 in FIGS. 9A-9C. With this configuration, it is possible to more effectively prevent the moving part 20 from being pushed in by mistake. In addition, the strength of the guards 211 is increased by connecting the guards 211 and the connecting plate 212, so that damage to the guards 211 can be prevented.

[0053] 11, the cover body 310 may have a large diameter portion 311 formed at the end on the tip opening 12b side, the large diameter portion 311 extending outward. The upper surface of the large diameter portion 311 may be flat, but need not be flat.
