Description

  The present invention relates to an insulator binding used when an electric wire is fixed to an insulator.

Conventionally, in order to fix a covered electric wire to a pin insulator, a winding binding for insulated wires and a binding binding for armrests have been used. Also if there is a connection point to the edge line portion, the distance between the cover of the connection point between the winding bind because it is necessary to secure more than 5 cm, insulated wire wrapper server India, with抱腕for gold winding can not be used to bind, vinyl coated Arumiba India (hereinafter, referred to as aluminum bound) is used instead.

The pin insulator 101 has a shoulder portion 105 at the top of a cylindrical body portion 103, and has a neck portion 107 having a diameter smaller than that of the body portion 103 following the shoulder portion 105. Further, a head portion 109 larger than the diameter of the neck portion 107 is provided above the neck portion 107, and a concave portion 113 for fixing an electric wire is provided on an upper surface 111 of the head portion 109.

Comparing the diameter d ₁ = 2r _{1 of} the trunk 103, the diameter d ₂ = 2r _{2 of} the neck 107, and the diameter d ₃ = 2r ₃ of the head 109, d ₁ > d ₃ > d ₂ , and the neck 107 of the smallest diameter of the diameter d _2. The pin lever 101 includes a mounting bolt 115 at the center, and is fixed to the arm metal via the mounting bolt 115.

  The insulator bind 1 is a bind for fixing the electric wire 201 to the pin insulator 101, and an insulator engaging portion 11 that engages with the neck portion 107 of the pin insulator 101, and an electric wire grip portion 31 that engages with the electric wire 201. The indirect live wire tool locking portion 41 is engaged with the indirect live wire tool, and the insulator locking portion 11 and the wire grip portion 31 are connected to each other via the connecting portion 21.

  The insulator binding 1 is a wire in which an insulator engaging portion 11, a connecting portion 21, an electric wire grip portion 31, and an indirect live wire tool engaging portion 41 are insulated and coated with a metal wire such as a steel wire having elasticity and high tension with a resin or the like. It is integrally formed with a body. If an example of the magnitude | size of the insulator bind 1 is shown, the diameter of a metal wire is about 2.5 mm and an outer diameter is about 4.2 mm. The insulator bind 1 may be joined after the respective parts have been manufactured separately, but can be easily and inexpensively manufactured by forming them integrally with a linear body.

Insulator locking portion 11 has a central portion 13 the radius of curvature R ₂ in the vicinity are radius r ₂ and equal to or slightly larger set of neck 107, a portion separated from the central portion 13 of the insulator locking portion 11 The diameter gradually increases as the distance from the central portion 13 increases, and the radius of curvature R ₃ of both end portions 15 is set to be the same as or slightly larger than the radius r ₃ of the head 109 of the pin insulator 101.

  The size of the lever locking portion 11 may be set so that the lever locking portion 11 can be locked to the neck portion 107 of the pin lever 101, but the size of the lever locking portion 11 is set as in this embodiment. By doing so, the lever locking portion 11 can be securely and securely locked to the neck portion 107 of the pin lever 101.

The connecting portion 21 is a portion that connects the insulator locking portion 11 and the wire grip portion 31, and extends linearly from both end portions 15 of the insulator locking portion 11. In the connecting portion 21, the distance between the left and right base end portions 23 is the same as or slightly larger than the diameter d _{3 of the} head, and the distance between the left and right gradually increases as the wire grip portion 31 is approached. Note that both end portions 15 of the lever locking portion 11 and the base end portion 23 of the connecting portion 21 are at the same position.

  As described above, the distance between the left and right sides of the connecting portion 21 is set so that the wire grip portion 31 is at a height higher than the head 109 in a state where the lever locking portion 11 is locked to the neck portion 107 of the lever binding 1. Can be lifted (see FIG. 4). This facilitates fixing of the electric wire 201 to the pin insulator 101 using the insulator bind 1.

In order to lift the wire grip portion 31 to a height higher than the head 109 of the pin lever 101 in a state where the lever lock portion 11 is locked to the neck portion 107 of the pin lever 101, the distance between the right and left of the connecting portion 21 is set. it is necessary to the diameter d ₃ or more heads 109, but stability when fixing the electrical wire 201 to the pin insulator 101 is lowered when widely unnecessarily. To stably fix the pin insulator 101 to the wire 201, the distance between the left and right inner arcuate portion 33 of the wire grip portions 31, having a diameter d ₁ of the body portion 103 of the pin insulator 101 is preferred.

  Further, the length L of the lever locking portion 11 and the connecting portion 21 is set so that the position of the wire grip portion 31 is a predetermined position. This point will be described later.

The support portion 37 may be linear in a plan view. However, if the support portion 37 is bent as described above, only the central portion first contacts the electric wire 201 when fitted into the electric wire 201, and then both end portions thereof are connected to the electric wire 201. Therefore, it is possible to fit into the electric wire 201 without difficulty, and the electric wire 201 can be firmly supported after the fitting.

The length of the support portion 37 is not limited to a specific length, but if it is extremely short, the arc-shaped portions 33 and 35 are close to each other, so that the stability when the electric wire 201 is fixed to the pin insulator 101 is improved. descend. On the other hand, if the support part 37 is lengthened, the electric wire 201 can be stably fixed to the pin insulator 101, but the operability at the time of attachment / detachment is reduced. If the diameter _{d 1} of the body 103 is a pin insulator of about 100 mm, the length of the support 37 may, if the order of 20 to 40 mm.

Distance L between the wire grip portion 31 and the insulator locking portion 11 is equal to or slightly larger setting a value obtained by adding the radius r _w of the wire 201 to the diameter d ₂ of the neck 103 of the pin insulator 101. Here, the distance L between the wire grip portion 31 and the lever locking portion 11 is a distance from the inner wall surface of the central portion 13 of the lever locking portion 11 to the center line M of the wire grip portion 31.

As described above, the radius of curvature R ₄ of the arc-shaped portions 33 and 35 of the wire grip portion 31 is set to be the same as or slightly larger than the radius r _{w of the} wire 201, and the support portion 37 is obliquely below instead of right next to the wire 201. Since it is set to support and the wire grip portion 31 is formed of a member having elasticity, the wire 201 can be firmly held by the wire grip portion 31.

Further insulator bound 1, the distance L between the wire grip portion 31 and the insulator locking portion 11, the diameter d ₂ of the neck 103 of the pin insulator 101 equal to or slightly larger value obtained by adding the radius r _w of the wire 201 Since it is set, the electric wire 201 can be fixed in a state where the electric wire 201 is in contact with the neck portion 107 of the pin insulator 101. Thereby, the electric wire 201 can be firmly fixed to the pin insulator 101.
