Description
本發明係有關於一種緊線器及使用此之活線排序工具。更具體而言，有關於可防止當鋁電線被夾固並拉到切斷位置時損壞到鋁電線之包覆構件的緊線器及使用此之活線排序工具。 The invention relates to a thread tightening device and a thread sorting tool using the thread tightening device. More specifically, it relates to a wire tightener that can prevent damage to the covering member of the aluminum wire when the aluminum wire is clamped and pulled to the cutting position, and a live wire sorting tool using the same.
傳統上，為了要在期望的位置上切斷架設在空中的電線桿等且為導電狀態下的電線(以下，稱之為活線(hot line))，就要使用一對緊線器分別夾固電線中欲切斷位置兩側的部分，再藉由使用伸縮桿等之拉伸用工具使此等一對緊線器彼此靠近，就可以在切斷位置附近彎曲且切斷電線。 Traditionally, in order to cut a conductive wire (hereinafter referred to as a hot line), such as a telegraph pole in the air, at a desired position, a pair of wire tensioners are used to clamp the wires respectively. Fix the parts on both sides of the position where the wire is to be cut, and then use a stretching tool such as a telescopic rod to bring the pair of tensioners close to each other, and the wire can be bent and cut near the cutting position.
傳統的緊線器，例如如專利文獻1中所述，具備有上側緊線體和下側緊線體作為從上下方夾固電線的部分。在上側緊線體和下側緊線體的對向面上，分別形成有半圓形剖面的凹溝。在將上側緊線體固定在底座等之狀態下，藉由向上移動下側緊線體，可以在嵌合於上側緊線體和下側緊線體的各個凹溝狀態下夾固電線。 A conventional wire tightening device, for example, as described in
此種緊線器通常在上側緊線體和下側緊線體的凹溝內部中設置有一突起(所謂尖釘(spike))，使得當電線被夾固並被拉向切斷位置時讓電線固定不會滑移。當電線被夾固並被拉向切斷位置時，藉由尖釘咬入到電線中以防止電線往軸向滑動。 This kind of wire tensioner is usually provided with a protrusion (so-called spike) in the recesses of the upper wire body and the lower wire body, so that when the wire is clamped and pulled to the cutting position, the wire Fixed and will not slip. When the wire is clamped and pulled to the cutting position, the spike is bitten into the wire to prevent the wire from sliding in the axial direction.
各種電線中最普及化的銅電線，具有以包覆構件覆蓋銅線的構造。若以緊線器夾固此種銅線時，可確實地防止當銅電線被尖釘咬入包覆構件 內部的銅線而拉動銅線時之滑動。 The most popular copper wire among various wires has a structure in which the copper wire is covered with a covering member. If a wire tensioner is used to clamp such a copper wire, it can be reliably prevented from sliding when the copper wire is bitten into the copper wire inside the covering member by a spike.
另一方面，具備近年來普及的鋁製的線材(以下稱為鋁電線)，雖其具有比銅線更便宜且輕量化的優點，但是當尖釘咬入鋁線材時，其比銅線更容易損壞，此外，有可能發生電氣性之影響，例如，加大電阻或火花等。因此，具有尖釘的緊線器不能用於夾固鋁電線。 On the other hand, aluminum wires (hereinafter referred to as aluminum wires), which have become popular in recent years, have the advantages of being cheaper and lighter than copper wires, but when spikes bite into the aluminum wires, they are more expensive than copper wires. It is easy to be damaged. In addition, electrical effects may occur, such as increased resistance or sparks. Therefore, a wire tensioner with spikes cannot be used to clamp aluminum wires.
傳統上，為了要在沒有尖釘的情況下夾固鋁電線，在上側緊線體和下側緊線體的相對面上，在此等上側緊線體和下側緊線體的全程上形成具有半圓形剖面的凹槽，該凹槽與鋁電線的外圍面緊密接觸。然而，當鋁電線從兩側拉到切斷位置並向上彎曲時，因為鋁電線的上側部分在遠離上側緊線體的半圓形剖面凹槽中的切斷位置的端部處被集中地強按壓在凹槽的最深部分上，所以鋁電線的上側部分可能會損壞鋁電線的包覆構件。 Traditionally, in order to clamp the aluminum wire without sharp nails, the upper side and the lower side of the wire body are formed on the opposite side of the upper side wire body and the lower side wire body. A groove with a semicircular cross-section that is in close contact with the outer surface of the aluminum wire. However, when the aluminum wire is pulled from both sides to the cut position and bent upward, because the upper part of the aluminum wire is concentrated and strong at the end away from the cut position in the semicircular cross-sectional groove of the upper tightening body Press on the deepest part of the groove, so the upper part of the aluminum wire may damage the covering member of the aluminum wire.
因此，為了分散施加在鋁電線上的應力，會想到將上側緊線體的凹槽形成為V字形而當鋁電線被拉到切斷位置時，分散施加到鋁電線上側部分的應力。然而，即使在此種情況下，也無法防止在遠離上側緊線體的V字形凹槽中的切斷位置的端部之鋁電線的包覆構件被損壞。 Therefore, in order to disperse the stress applied to the aluminum wire, it is conceivable to form the groove of the upper side tightening body into a V shape so that when the aluminum wire is pulled to the cutting position, the stress applied to the upper part of the aluminum wire is dispersed. However, even in this case, it is impossible to prevent the covering member of the aluminum electric wire from being damaged at the end far from the cut position in the V-shaped groove of the upper side tightening body.

本發明係為了解決上述之習知技術的問題而發明之。其目的將提供一種緊線器及使用此之活線排序工具，其可防止當鋁電線被夾固並拉到切斷位置時損壞到鋁電線之包覆構件。 The present invention is invented to solve the above-mentioned problems of the conventional technology. Its purpose is to provide a wire tightening device and a live wire sorting tool using the same, which can prevent damage to the covering member of the aluminum wire when the aluminum wire is clamped and pulled to the cutting position.
本發明之緊線器，其特徵係用以鋁電線且為了切斷在空中架設狀 態下之鋁電線，該鋁電線係被包覆構件覆蓋鋁材質的線材，用以在切斷位置附近夾固鋁電線，其具備：一支架部，其下面形成有嵌合溝，該嵌合溝係從該鋁電線的上方嵌入；一凸輪構件，配置於該支架部的下側，且在其上表面形成有支撐槽用於從下方支撐鋁電線；一間隔調整部，用以調整該凸輪構件和支架部之間隔；以及一連結部，能夠在上下方向擺動自如地連接到拉伸用工具，該拉伸用工具往接近鋁電線的切斷位置的方向拉伸該緊線器；其中，該支架部的該嵌合溝，在接近該切斷位置的一側之第一端部中具有一V字形剖面，且在遠離該切斷位置的一側之第二端部中具有一半圓形剖面，更進一步，該嵌合溝具有一剖面變化部，該剖面變化部在包含該嵌合溝中遠離切斷位置的一側的第二端部的至少一部分，沿著該嵌合溝而逐漸接近該遠側的第二端部，從V字形剖面逐漸變為半圓形剖面。 The wire tightening device of the present invention is characterized by using aluminum wires to cut the aluminum wires in the aerial state. The aluminum wires are aluminum wires covered by a covering member to be clamped near the cutting position An aluminum electric wire comprising: a bracket portion with a fitting groove formed on the lower surface, and the fitting groove is fitted from above the aluminum wire; a cam member arranged on the lower side of the bracket portion and formed on the upper surface There are support grooves for supporting the aluminum wire from below; an interval adjusting part for adjusting the interval between the cam member and the bracket part; and a connecting part that can be swingably connected to the stretching tool in the vertical direction. Use a tool to stretch the wire tensioner in the direction close to the cutting position of the aluminum wire; wherein the fitting groove of the bracket part has a V-shaped cross section in the first end of the side close to the cutting position , And has a semicircular cross-section in the second end on the side far from the cutting position, and further, the fitting groove has a cross-sectional change portion, and the cross-sectional change portion includes the fitting groove away from the cut At least a part of the second end on the side of the position gradually approaches the second end on the distal side along the fitting groove, and gradually changes from a V-shaped cross section to a semicircular cross section.
於本發明之緊線器上，當為了切斷在空中架設狀態下之鋁電線而在切斷位置附近夾固鋁電線時，支架部的嵌合溝將被嵌合到鋁電線的上側部分，在此狀態下，藉由間隔調整部來調整為往縮小凸輪構件和支架部之間的間隔之方向，讓鋁電線的下側部分嵌合到凸輪構件的支撐槽內。藉此，鋁電線被夾固在凸輪構件和支架部之間並處於緊線狀態。 In the wire tightening device of the present invention, when the aluminum wire is clamped near the cutting position in order to cut the aluminum wire in the aerial state, the fitting groove of the bracket part will be fitted to the upper part of the aluminum wire, In this state, the gap adjustment portion is used to adjust to reduce the gap between the cam member and the bracket portion, and the lower part of the aluminum wire is fitted into the support groove of the cam member. Thereby, the aluminum electric wire is clamped between the cam member and the bracket part and is in a tight wire state.
當藉由拉伸用工具往接近切斷位置的方向拉伸緊線器時，鋁電線在切斷位置附近彎曲。此時，對應於彎曲度，緊線器在與拉伸用工具的連結部往上下方向擺動，且凸輪構件和支架部位在遠離切斷位置一側的端部下降。同時，鋁電線的上側部分用力地按壓在支架部之嵌合溝的內表面上。 When the tensioner is pulled in the direction close to the cutting position by the stretching tool, the aluminum wire bends near the cutting position. At this time, in accordance with the degree of curvature, the tensioner swings in the up and down direction at the connection portion with the stretching tool, and the cam member and the bracket portion are lowered at the end away from the cutting position. At the same time, the upper part of the aluminum wire is strongly pressed against the inner surface of the fitting groove of the bracket part.
嵌合溝在接近切斷位置的一側之第一端部中具有一V字形剖面，且在遠離切斷位置的一側之第二端部中具有一半圓形剖面，且具有一剖面變化部，該剖面變化部在包含該嵌合溝中遠側的第二端部的至少一部分，沿著該嵌合溝而逐漸接近該遠側的第二端部，從V字形剖面逐漸變為半圓形剖面。 The fitting groove has a V-shaped cross section at the first end on the side close to the cutting position, and has a semicircular cross section at the second end on the side far from the cutting position, and has a cross-sectional change portion , The cross-sectional change portion includes at least a part of the distal second end of the fitting groove, and gradually approaches the distal second end along the fitting groove, gradually changing from a V-shaped cross section to a semicircular shape profile.
因此，在嵌合溝中接近切斷位置附近的部分，藉由讓構成V字形剖面的兩個表面分別用力地按壓在鋁電線的上側部分，從寬度方向的兩側夾固鋁電線就可以穩定地支撐鋁電線，使得鋁電線不會在鋁電線的軸向或寬度方向上移位。 Therefore, in the part near the cutting position in the fitting groove, the two surfaces constituting the V-shaped cross-section are firmly pressed against the upper part of the aluminum wire, and the aluminum wire is clamped from both sides in the width direction to stabilize. Ground the aluminum wire so that the aluminum wire will not be displaced in the axial or width direction of the aluminum wire.
此外，在包含嵌合溝中遠側的第二端部的剖面變化部，具有隨著接近嵌合溝遠側的第二端部，而讓嵌合溝之剖面從V字形剖面逐漸變為半圓形剖面之形狀。故，鋁電線上側部分的支撐狀態，係隨著遠離切斷位置，藉由V字形剖面的兩個表面，從由在寬度方向兩側以兩個點被支撐的狀態平滑地變化到由半圓形剖面的彎曲面在寬度方向上以寬接觸面支撐的狀態。因此，即使在接近嵌合溝遠側的第二端部的部分中，也可以抑制在該軸向和寬度方向上的位移，同時可穩定地支撐鋁電線。 In addition, the cross-sectional change portion including the distal second end of the fitting groove gradually changes the cross-section of the fitting groove from a V-shaped cross section to a semicircle as it approaches the second distal end of the fitting groove. The shape of the cross-section. Therefore, the supporting state of the upper part of the aluminum wire changes smoothly from the state of being supported at two points on both sides in the width direction to the semicircle The curved surface of the cross-sectional shape is supported by a wide contact surface in the width direction. Therefore, even in the portion close to the second end portion on the far side of the fitting groove, the displacement in the axial and width directions can be suppressed, and the aluminum electric wire can be stably supported.
此外，鋁電線在切斷位置向上彎曲狀態下，由於嵌合溝之遠側的第二端部係位於第一端部下方，所以鋁電線的上側端部會受到最用力的按壓。然而，遠側的第二端部具有半圓形剖面，所以即使鋁電線的上側端部被用力按壓在嵌合溝上，也可利用在嵌合溝的遠側的第二端部的半圓形剖面的彎曲面，在寬度方向上將力量分散到寬的接觸面上且加以支撐。 In addition, when the aluminum wire is bent upward at the cutting position, since the distal second end of the fitting groove is located below the first end, the upper end of the aluminum wire is pressed most strongly. However, the distal second end has a semicircular cross section, so even if the upper end of the aluminum wire is pressed against the fitting groove forcibly, the semicircular shape of the second end distal to the fitting groove can be used The curved surface of the section distributes the force to the wide contact surface and supports it in the width direction.
結果，鋁電線被穩定地支撐，使其在支架部之嵌合溝的整個長度上不會在軸向和寬度方向上移位，且由於鋁電線被按壓在嵌合溝的遠側之第二端部，所以可防止鋁電線的包覆構件受到破損或損壞。 As a result, the aluminum wire is stably supported so that it will not be displaced in the axial and width directions over the entire length of the fitting groove of the stent part, and since the aluminum wire is pressed on the second distal side of the fitting groove End, so it can prevent the aluminum wire coating member from being damaged or damaged.
該支架部在該嵌合溝中遠離切斷位置的一側上的第二端部的邊緣較佳為倒角。 The edge of the second end of the bracket portion on the side away from the cutting position in the fitting groove is preferably chamfered.
藉由此種構造，當以緊線器夾固鋁電線並將其拉到切斷位置時，即使鋁電線的上側部分被按壓在遠離嵌合溝的切斷位置一側的第二端部的邊緣上，該力量將藉由該邊緣之倒角所形成的寬接觸面而分散。因此，可確實地防止或抑制因鋁電線與嵌合溝的邊緣的接觸而讓鋁電線的包覆構件受到破損或損壞。 With this structure, when the aluminum wire is clamped with a wire tensioner and pulled to the cutting position, even if the upper part of the aluminum wire is pressed at the second end on the side away from the cutting position of the fitting groove On the edge, the force will be dispersed by the wide contact surface formed by the chamfer of the edge. Therefore, it is possible to reliably prevent or suppress damage or damage to the covering member of the aluminum wire due to the contact between the aluminum wire and the edge of the fitting groove.
該嵌合溝中的該第二端部的半圓形剖面，係形成為比該第一端部的V字形剖面的深度更深，從相對於該剖面變化部中該V字形剖面的底部延伸的線的V字形剖面，逐漸變化為半圓形剖面的部分的底部延伸的線之角度，較佳基於在該鋁電線被拉到切斷位置的狀態下之鋁電線的彎曲度來設定。 The semicircular cross-section of the second end of the fitting groove is formed deeper than the depth of the V-shaped cross-section of the first end, and extends from the bottom of the V-shaped cross-section relative to the cross-sectional change portion The V-shaped cross-section of the wire gradually changes to the angle of the line extending from the bottom of the semicircular cross-sectional portion, which is preferably set based on the degree of curvature of the aluminum wire when the aluminum wire is pulled to the cutting position.
鋁電線依據鋁電線的電線粗細度等，當鋁電線被拉到切斷位置時，其彎曲度有所不同。因此，為了應對此種鋁電線的彎曲度，在上述構造中，該嵌合溝中的該第二端部的半圓形剖面，在形成為比該第一端部的V字形剖面的深度更深之構造中，從相對於該剖面變化部中該V字形剖面的底部延伸的線的V字形剖面，逐漸變化為半圓形剖面的部分的底部延伸的線之角度，係基於在該鋁電線被拉到切斷位置的狀態下之鋁電線的彎曲度來設定。因此，當鋁電線被拉向切斷位置時，雖鋁電線在向上彎曲狀態下鋁電線被按壓在支架部上，但鋁電線按壓於支架部的力量係可被分散且支撐在整個剖面變化部。此結果，可確實地防止力量集中在該嵌合溝的遠側的第二端部上，且可更確實地抑制在嵌合溝的遠側的第二端部的鋁電線的包覆構件受到破損或損壞。 According to the thickness of the aluminum wire, the bending degree of the aluminum wire is different when the aluminum wire is pulled to the cutting position. Therefore, in order to cope with the curvature of such aluminum wires, in the above-mentioned structure, the semicircular cross section of the second end of the fitting groove is formed deeper than the depth of the V-shaped cross section of the first end. In the structure, the angle of the line extending from the line extending from the bottom of the V-shaped cross section to the bottom of the V-shaped cross section in the section changing part gradually changes to the line extending from the bottom of the semicircular cross section is based on the aluminum wire being Set the bending degree of the aluminum wire when it is pulled to the cut position. Therefore, when the aluminum wire is pulled to the cutting position, although the aluminum wire is pressed on the bracket part when the aluminum wire is bent upward, the force system of the aluminum wire pressing the bracket part can be dispersed and supported in the entire section change part . As a result, it is possible to reliably prevent the force from being concentrated on the distal second end of the fitting groove, and it is possible to more reliably prevent the aluminum wire covering member at the distal second end of the fitting groove from receiving Broken or damaged.
該支架部較佳係以可裝卸方式安裝在該間隔調整部。利用此種構造，可以更換為具有與該鋁電線的粗細度相對應的嵌合溝之該支架。 Preferably, the bracket part is detachably installed on the interval adjusting part. With this structure, it is possible to replace the bracket with a fitting groove corresponding to the thickness of the aluminum wire.
該凸輪構件及該支架部，較佳係以裝卸方式安裝於該間隔調整部。藉由此種構造，不僅可以更換為具有與該鋁電線的粗細度相對應的嵌合溝之該支架，也可以更換為具有尖釘(突起)之凸輪構件和支架部，該尖釘(突起)適合於夾固由鋁電線以外的材質的電線，例如具有銅線的線。結果，廣泛使用緊線器。 The cam member and the bracket part are preferably installed on the interval adjusting part in a removable manner. With this structure, it is possible to replace not only the bracket with a fitting groove corresponding to the thickness of the aluminum wire, but also a cam member and bracket with spikes (protrusions). ) Is suitable for clamping wires made of materials other than aluminum wires, such as wires with copper wires. As a result, wire tensioners are widely used.

The aluminum wire is an aluminum wire covered by a covering member, and the aluminum wire is clamped on both sides near the cutting position. And pull the aluminum wire to the cutting position from both sides. The wire tensioner is provided with a pair of wire tensioners for clamping the aluminum wire on both sides of the cutting position; and a stretching tool for A pair of wire tensioners are respectively stretched in the direction close to the cutting position of the aluminum wire; the stretching tool includes a telescopic rod that can be stretched freely; and the connecting parts of the pair of wire tensioners are connected to the two telescopic rods. The end is connected to the telescopic rod for the pair of tensioners to swing up and down freely.
藉由此種構造，藉由如上所述構成的一對緊線器來夾固鋁電線的切斷位置的兩側，藉由拉伸用工具的伸縮桿將一對緊線器分別往接近鋁電線的切斷位置的方向上拉伸。藉此，鋁電線可以很容易地從兩側將鋁電線拉到切斷位置，同時，可以防止在鋁電線中的切斷位置的兩側部分由緊線器所夾固的部分中的鋁電線的包覆構件受到破損或損壞。 With this structure, a pair of wire tensioners constructed as described above is used to clamp both sides of the cutting position of the aluminum wire, and the pair of wire tensioners are respectively approached to the aluminum by the telescopic rod of the stretching tool. The wire is stretched in the direction of the cut position.

其次，將參考附圖更詳細地說明本發明的緊線器及使用此之活線排序工具之實施例。 Next, with reference to the accompanying drawings, the embodiment of the thread tightening device and the thread sorting tool of the present invention will be described in more detail.
圖1為表示具備本發明之實施例的鋁電線(W)用的緊線器(2)的活線排序工具(1)。 Fig. 1 shows a live thread sorting tool (1) equipped with a wire tensioner (2) for an aluminum wire (W) according to an embodiment of the present invention.
圖1所示之活線排序工具(1)，係為了切斷架設在空中狀態下之鋁電線(W)，該鋁電線(W)係被包覆構件覆蓋鋁材質的線材，在該切斷位置(CT)附近的兩側夾固鋁電線，並從兩側將該鋁電線(W)拉到該切斷位置(CT)。 The live thread sorting tool (1) shown in Figure 1 is designed to cut the aluminum wire (W) that is installed in the air. The aluminum wire (W) is an aluminum wire covered by a covering member. The aluminum wire is clamped on both sides near the position (CT), and the aluminum wire (W) is pulled to the cutting position (CT) from both sides.
具體而言，活線排序工具(1)，其具備：一對緊線器(2)，在切斷位置(CT)之兩側夾固鋁電線(W)；以及一拉伸用工具(3)，將該一對緊線器(3)分別往接近鋁電線(W)切斷位置的方向(P)拉伸。又，為一對緊線器(2)指定左右任一緊線器稱呼時，圖1的右側緊線器稱為緊線器(2R)，左側緊線器稱為緊線器(2L)。 Specifically, a live thread sorting tool (1) is provided with: a pair of wire tensioners (2) for clamping aluminum wires (W) on both sides of the cutting position (CT); and a stretching tool (3) ), pull the pair of tensioners (3) in the direction (P) close to the cutting position of the aluminum wire (W). In addition, when a pair of tensioners (2) is designated as either left or right tensioner, the right tensioner in Figure 1 is called the tensioner (2R), and the left tensioner is called the tensioner (2L).
拉伸用工具(3)，包含伸縮自如的伸縮桿(3a)及設置於伸縮桿(3a)兩端部之支撐部(3b)。 The stretching tool (3) includes a telescopic rod (3a) that can stretch freely and support parts (3b) arranged at both ends of the telescopic rod (3a).
圖2和圖3所示的緊線器(2)，具有可以在切斷位置(CT)附近夾固鋁電線(W)以便切斷在空中架設狀態下之鋁電線的構造。又，圖2顯示出切斷位置(CT)右側的緊線器(2R)，圖3顯示出切斷位置(CT)左側的緊線器(2L)。此等右側緊線器(2R)和左側緊線器(2L)，基本構造雖相同，但相對於切斷位置(CT)為對稱。 The wire tightener (2) shown in Figures 2 and 3 has a structure that can clamp the aluminum wire (W) near the cutting position (CT) to cut the aluminum wire in the air-installed state. Also, Figure 2 shows the thread tensioner (2R) on the right side of the cutting position (CT), and Figure 3 shows the thread tensioner (2L) on the left side of the cutting position (CT). Although the basic structure of the right thread tensioner (2R) and the left thread tensioner (2L) are the same, they are symmetrical with respect to the cutting position (CT).
圖2和圖3所示之任一緊線器(2)，具備：一支架部(4)、配置於支架部(4)下方之凸輪構件(5)、一間隔調整部(6)，用以調整支架部(4)與凸輪構件(5)之間隔及一連結部(7)，與上述拉伸用工具(3)之支撐部(3b)連結(如圖1所示)。於配置在上下的支架部(4)及凸輪構件(5)之間，藉由夾固該鋁電線(W)，可讓緊線器(2)夾固鋁電線(W)。 Any one of the tensioners (2) shown in Figures 2 and 3 is provided with: a bracket part (4), a cam member (5) arranged below the bracket part (4), and an interval adjusting part (6). The distance between the bracket part (4) and the cam member (5) and a connecting part (7) are connected with the supporting part (3b) of the stretching tool (3) (as shown in Figure 1). The aluminum wire (W) is clamped between the upper and lower bracket parts (4) and the cam member (5), so that the wire tensioner (2) can clamp the aluminum wire (W).
以下，舉出緊線器(2R)的支架部(4)、凸輪構件(5)、間隔調整部(6)和連結部(7)為示例且說明緊線器(2)之具體構造。 Hereinafter, the bracket part (4), the cam member (5), the interval adjusting part (6) and the connecting part (7) of the tensioner (2R) are taken as examples and the specific structure of the tensioner (2) is described.
支架部(4)係用於從上方支撐鋁電線的金屬製之塊狀構件。在支架部(4)的下表面，形成一從上方嵌合到鋁電線(W)中的嵌合溝(4a)。 The bracket part (4) is a metal block member for supporting the aluminum wire from above. A fitting groove (4a) fitted into the aluminum wire (W) from above is formed on the lower surface of the bracket part (4).
圖4為表示圖1的右側緊線器中的32平方鋁電線用的支架部圖，其中(a)為表示前視圖，(b)為表示底視圖，(c)為表示從箭頭C方向觀察(a)的緊線器的圖，(d)為示意性表示嵌合溝的第一端部的V字形剖面圖，(e)為示意性表示(a)的E-E線剖面中的嵌合溝的剖面變化部的剖面圖，(f)為示意性表示嵌合溝的第二端部的半圓形剖面圖。 Figure 4 is a diagram showing the bracket part for the 32 square aluminum wire in the right tightening device of Figure 1, in which (a) is a front view, (b) is a bottom view, and (c) is a view from the direction of arrow C (a) is a drawing of the tensioner, (d) is a V-shaped cross-sectional view schematically showing the first end of the fitting groove, and (e) is a diagram schematically showing the fitting groove in the EE line cross section of (a) (F) is a cross-sectional view of the cross-sectional change portion of, (f) is a semicircular cross-sectional view schematically showing the second end of the fitting groove.
如圖(4a)至4(f)所示，支架部(4)的嵌合溝(4a)在接近切斷位置(CT)之一側的第一端部(4a1)中，具有V字形剖面(如圖4(d)所示)。另外，在遠離嵌合溝(4a)之切斷位置(CT)之一側的第二端部(4a2)中，具有半圓形剖面(如圖4(f)所示)。 As shown in Figures (4a) to 4(f), the fitting groove (4a) of the bracket part (4) has a V-shaped cross-section in the first end part (4a1) on one side close to the cutting position (CT) (As shown in Figure 4(d)). In addition, the second end (4a2) on one side away from the cutting position (CT) of the fitting groove (4a) has a semicircular cross section (as shown in FIG. 4(f)).
再者，該嵌合溝(4a)具有一剖面變化部(4c)，該剖面變化部(4c)在包含該嵌合溝(4a)中遠離切斷位置(CT)的一側的第二端部(4a2)的至少一部分，沿著嵌合溝(4a)而逐漸接近遠側的第二端部(4a2)，從V字形剖面逐漸變為半圓形剖面。具體而言，在此嵌合溝(4a)的剖面變化部(4c)中，如圖4(e)所示，嵌合溝(4a)從V字形剖面從下方逐漸變為半圓形剖面。Furthermore, the fitting groove (4a) has a cross-sectional change portion (4c), and the cross-sectional change portion (4c) includes the second end of the fitting groove (4a) on the side away from the cutting position (CT) At least a part of the portion (4a2) gradually approaches the second distal end portion (4a2) along the fitting groove (4a), and gradually changes from a V-shaped cross section to a semicircular cross section. Specifically, in the cross-sectional change portion (4c) of this fitting groove (4a), as shown in FIG. 4(e), the fitting groove (4a) gradually changes from a V-shaped cross section to a semicircular cross section from below.
剖面變化部(4c)之範圍，在嵌合溝(4a)的全長中，只要涵蓋有第二端部(4a2)的至少一部分即可，在本發明中並沒有特別限定。例如，將其設定在嵌合溝(4a)的總長度之約1/2至1/4的範圍內，但是剖面變化部(4c)也可以形成在嵌合溝(4a)的整個長度上。 The range of the cross-sectional change portion (4c) is not particularly limited in the present invention as long as it covers at least a part of the second end portion (4a2) over the entire length of the fitting groove (4a). For example, it is set in the range of about 1/2 to 1/4 of the total length of the fitting groove (4a), but the cross-sectional change portion (4c) may be formed over the entire length of the fitting groove (4a).
如圖4(a)所示，嵌合溝(4a)中的該第二端部(4a2)的半圓形剖面，係形成為比第一端部(4a1)的V字形剖面的深度更深。於此構造中，從相對於剖面變化部(4c)中V字形剖面的底部延伸的線(4e)的V字形剖面，逐漸變化為半圓形剖面的部分的底部延伸的線(4f)之角度θ1，係基於在鋁電線(W)被拉到切斷位置(CT)的狀態下之鋁電線(W)的彎曲度來設定。 As shown in Fig. 4(a), the semicircular cross section of the second end (4a2) in the fitting groove (4a) is formed deeper than the V-shaped cross section of the first end (4a1). In this structure, the V-shaped cross-section from the line (4e) extending from the bottom of the V-shaped cross-section in the section changing part (4c) gradually changes to the angle of the line (4f) extending from the bottom of the semicircular cross-section θ1 is set based on the degree of bending of the aluminum wire (W) when the aluminum wire (W) is pulled to the cutting position (CT).
細的鋁電線(W)，(例如，在32平方的情況下(亦即，額定剖面積為32平方毫米的鋁電線)，因鋁電線(W)彎曲很大，因此會考慮到彎曲度，上述角度θ1設定為約2度。另一方面，在粗鋁電線(W)的情況下(例如，120平方(亦即，額定剖面積為120平方毫米的鋁電線)，鋁電線(W)的彎曲度小於32平方之鋁電線的彎曲度。因此，考慮到這一點，在對應於如圖(6a)至6(c)所示的120平方鋁電線的支架部4中，角度θ2被設定為約1度。 Thin aluminum wires (W), (for example, in the case of 32 square meters (that is, aluminum wires with a rated cross-sectional area of 32 square millimeters), because the aluminum wires (W) bend a lot, the degree of bending will be considered. The above-mentioned angle θ1 is set to about 2 degrees. On the other hand, in the case of a thick aluminum wire (W) (for example, 120 square (that is, an aluminum wire with a rated cross-sectional area of 120 square millimeters), the aluminum wire (W) The degree of curvature of the aluminum wire is less than 32 square. Therefore, in consideration of this point, in the
此外，在圖4(a)和(f)所示的支架部(4)中，在嵌合溝(4a)中遠離切斷位置(CT)的一側的第二端部(4a2)的邊緣為倒角。具體而言，在第二端部(4a2)的遠離嵌合溝(4a)中的切斷位置(CT)的一側的邊緣，形成一倒角部分(4d)，該倒角部分(4d)為圓形(所謂R)，以便可以去除該邊緣的角部。又，倒角部分(4d)只要去除嵌合溝(4a)的邊緣的角部即可，或也可傾切邊緣的角並移除的部分(所謂C面)。 In addition, in the bracket portion (4) shown in Figures 4(a) and (f), the edge of the second end portion (4a2) on the side away from the cutting position (CT) in the fitting groove (4a) For chamfering. Specifically, a chamfered portion (4d) is formed on the edge of the second end (4a2) on the side away from the cutting position (CT) in the fitting groove (4a), and the chamfered portion (4d) It is round (so-called R) so that the corners of the edge can be removed. In addition, the chamfered portion (4d) only needs to remove the corner portion of the edge of the fitting groove (4a), or the portion (so-called C-face) that the corner of the edge is chamfered and removed.
如圖1至3所示，凸輪構件(5)配置在支架部(4)下側，且具有能夠從下方支撐鋁電線(W)的構造。 As shown in Figs. 1 to 3, the cam member (5) is arranged on the lower side of the bracket part (4) and has a structure capable of supporting the aluminum wire (W) from below.
具體而言，如圖5(a)至5(c)所示，於凸輪構件(5)的上表面，形成有用於從下方支撐鋁電線(W)的支撐槽(5a)。 Specifically, as shown in Figs. 5(a) to 5(c), a support groove (5a) for supporting the aluminum wire (W) from below is formed on the upper surface of the cam member (5).
支撐槽(5a)在其整個長度上具有V字形剖面。因此，無論鋁電線(W)的粗細度如何，都可讓構成支撐槽(5a)的兩個表面從寬度方向的兩側支撐電線。 The supporting groove (5a) has a V-shaped cross section over its entire length. Therefore, regardless of the thickness of the aluminum wire (W), the two surfaces constituting the supporting groove (5a) can support the wire from both sides in the width direction.
此外，可防止凸輪構件(5)的支撐槽(5a)的內表面經過金屬材料等的熱噴塗等加工處理，而當使用活線排序工具(1)將鋁電線(W)拉到切斷位置(CT)時鋁電線(W)在支撐槽(5a)內部滑動。 In addition, it can prevent the inner surface of the support groove (5a) of the cam member (5) from being processed by thermal spraying of metal materials, etc., and when the wire sorting tool (1) is used to pull the aluminum wire (W) to the cutting position (CT) The aluminum wire (W) slides inside the support groove (5a).
此外，在凸輪構件(5)的下表面形成有一插槽(5b)，該插槽(5b)係用以***後述的間隔調整部(6)的箭頭部(6d1)。 In addition, a slot (5b) is formed on the lower surface of the cam member (5), and the slot (5b) is used to insert the arrow portion (6d1) of the interval adjusting portion (6) described later.
間隔調整部(6)，只要具有用於調整凸輪構件(5)和支架部(4)之間的間隔的構造即可，在本發明中，間隔調整部的具體構造並無特別限制。 The interval adjusting portion (6) only needs to have a structure for adjusting the interval between the cam member (5) and the bracket portion (4). In the present invention, the specific structure of the interval adjusting portion is not particularly limited.
例如，圖2所示的間隔調整部(6)具備：一基底部(6a)、以可裝卸方式將支架部(4)固定到基底部(6a)的固定部(6b)、用於將凸輪構件(5)安裝到基底部(6a)，以便可在上下方向移動之安裝部(6c)、及向上按壓凸輪構件(5)之按壓部(6d)。 For example, the interval adjusting portion (6) shown in Figure 2 has: a base portion (6a), a fixing portion (6b) that detachably fixes the bracket portion (4) to the base portion (6a), and a cam The member (5) is mounted to the base portion (6a) so that the mounting portion (6c) that can move in the up and down direction, and the pressing portion (6d) that presses the cam member (5) upward.
在基底部(6a)的頂部，安裝有固定部(6b)。固定部(6b)具有用以夾固(箝制)設置在支架部(4)頂部的突起機構。因此，在嵌合溝(4a)朝下的狀態下，支架部(4)可以裝卸方式安裝到基底部(6a)。 A fixing part (6b) is installed on the top of the base part (6a). The fixing part (6b) has a protruding mechanism for clamping (clamping) the protrusion provided on the top of the bracket part (4). Therefore, with the fitting groove (4a) facing downward, the bracket part (4) can be detachably mounted to the base part (6a).
安裝部(6c)具有圍繞上下部分(6a1)的外圍邊的形狀，該形狀係往基底部(6a)的上下方向延伸。凸輪構件(5)透過螺栓等且以可裝卸方式安裝在安裝部(6c)上。藉此，凸輪構件(5)可以配置成在支架部(4)下方沿上下方向移動。 The mounting portion (6c) has a shape surrounding the outer periphery of the upper and lower portions (6a1), and the shape extends in the vertical direction of the base portion (6a). The cam member (5) is detachably mounted on the mounting part (6c) through bolts and the like. Thereby, the cam member (5) can be arranged to move in the vertical direction under the bracket portion (4).
按壓部(6d)具有：可往水平方向移動的箭頭部(6d1)、可往上下方向移動的楔形部(6d2)、及用於向上按壓楔形部(6d2)的螺釘部(6d3)。箭頭部(6d1)的下方傾斜面(S1)抵靠在楔形部(6d2)的上方傾斜面(S2) 上。箭頭部(6d1)的上方，以微小的間隙嵌合在凸輪構件(5)的插槽(5b)中。因此，在插槽(5b)內部允許箭頭部(6d1)往水平方向上移動。 The pressing portion (6d) has an arrow portion (6d1) that can move in the horizontal direction, a wedge portion (6d2) that can move up and down, and a screw portion (6d3) for pressing the wedge portion (6d2) upward. The lower inclined surface (S1) of the arrow portion (6d1) abuts against the upper inclined surface (S2) of the wedge-shaped portion (6d2) on. The upper part of the arrow portion (6d1) is fitted into the slot (5b) of the cam member (5) with a small gap. Therefore, the arrow portion (6d1) is allowed to move in the horizontal direction inside the slot (5b).
螺釘部(6d3)係一桿狀的構件，其在外圍面上形成有螺紋，其被螺合到形成在水平部分(6a2)中的螺孔(未圖示)中，該水平部分(6a2)從基底部(6a)的垂直部分(6a1)的下端部分往水平方向延伸。因此，藉由旋轉螺釘部(6d3)，讓螺釘部(6d3)的上端部抬起楔形部(6d2)和箭頭部(6d1)。同時，箭頭部(6d1)的頂部在***到凸輪構件(5)的插槽(5b)的狀態下抬起凸輪構件(5)。結果，凸輪構件(5)可靠近支架部(4)並且可縮小支架部(4)和凸輪構件(5)之間的距離。可藉由此等支架部(4)和凸輪構件(5)而從上下方向夾固鋁電線(W)。 The screw portion (6d3) is a rod-shaped member with threads formed on the outer surface, which is screwed into a screw hole (not shown) formed in the horizontal portion (6a2), the horizontal portion (6a2) It extends horizontally from the lower end part of the vertical part (6a1) of the base part (6a). Therefore, by rotating the screw portion (6d3), the upper end portion of the screw portion (6d3) lifts the wedge portion (6d2) and the arrow portion (6d1). At the same time, the top of the arrow portion (6d1) lifts the cam member (5) in a state of being inserted into the slot (5b) of the cam member (5). As a result, the cam member (5) can be close to the bracket portion (4) and the distance between the bracket portion (4) and the cam member (5) can be reduced. The aluminum wire (W) can be clamped from the vertical direction by the bracket part (4) and the cam member (5).
如圖1至2所示，連結部(7)係可以在上下方向擺動自如地連接到支撐部(3b)的部分，該支撐部(3b)係設置在拉伸用工具(3)的伸縮桿(3a)的兩端部，用於在接近鋁電線(W)的切斷位置(CT)的方向(P)上拉伸緊線器(2)。 As shown in Figures 1 to 2, the connecting portion (7) is a part that can be swingably connected to the support portion (3b) in the vertical direction, and the support portion (3b) is set on the telescopic rod of the stretching tool (3) The ends of (3a) are used to stretch the wire tensioner (2) in the direction (P) approaching the cutting position (CT) of the aluminum wire (W).
圖2所示的連結部(7)係設置在間隔調整部(6)的按壓部(6d)的箭頭部(6d1)的端部。因此，箭頭部(6d1)透過連結部(7)和該支撐部(3b)而與拉伸用工具(3)的伸縮桿(3a)連接。因此，當伸縮桿(3a)收縮時，箭頭部(6d1)與連結部(7)都會在接近切斷位置(CT)的方向(P)上被拉出。此時，箭頭部(6d1)將沿著楔形部(6d2)的頂部斜面(S2)往上推。結果，位於箭頭部(6d1)上方的凸輪構件(5)也被向上推，從而增加了由支架部(4)和凸輪構件(5)夾固鋁電線(W)的力量(所謂拉緊)，進而可確實地抑制鋁電線(W)往軸向滑移。 The connecting portion (7) shown in FIG. 2 is provided at the end of the arrow portion (6d1) of the pressing portion (6d) of the interval adjusting portion (6). Therefore, the arrow portion (6d1) is connected to the telescopic rod (3a) of the stretching tool (3) through the connecting portion (7) and the support portion (3b). Therefore, when the telescopic rod (3a) contracts, both the arrow portion (6d1) and the connecting portion (7) are pulled out in the direction (P) approaching the cutting position (CT). At this time, the arrow portion (6d1) will be pushed up along the top slope (S2) of the wedge portion (6d2). As a result, the cam member (5) located above the arrow portion (6d1) is also pushed up, thereby increasing the force (so-called tightening) to clamp the aluminum wire (W) by the bracket portion (4) and the cam member (5), Furthermore, the sliding of the aluminum wire (W) in the axial direction can be reliably suppressed.
又，本實施例的連結部(7)係設置在間隔調整部(6)的按壓部(6d)之箭頭部(6d1)接近切斷位置(CT)的端部，但本發明並不限定於此。 例如，在沒有箭頭部(6d1)的緊線器(2)的情況下，連結部(7)也可以配置在基底部(6a)等處。 In addition, the connecting portion (7) of this embodiment is provided at the end of the arrow portion (6d1) of the pressing portion (6d) of the interval adjusting portion (6) close to the cutting position (CT), but the present invention is not limited to this. For example, in the case of the tensioner (2) without the arrow portion (6d1), the connecting portion (7) may be arranged at the base portion (6a) or the like.
此外，間隔調整部(6)雖藉由固定支架部(4)並讓凸輪構件(5)往上下方向移動來調整支架部(4)和凸輪構件(5)之間的間隔，但本發明並不限於此。作為另一個間隔調整部(6)，可採用固定凸輪構件(5)並讓支架部(4)往上下方向移動的構造，或者也可採用讓支架部(4)和凸輪構件(5)一起往上下方向移動的構造。 In addition, the interval adjusting portion (6) adjusts the interval between the bracket portion (4) and the cam member (5) by fixing the bracket portion (4) and moving the cam member (5) up and down, but the present invention does not Not limited to this. As another interval adjusting part (6), a structure in which the cam member (5) is fixed and the bracket part (4) moves up and down can be adopted, or the bracket part (4) and the cam member (5) can be moved together Structure to move up and down.
使用如以上所構成之緊線器(2)，當要切斷在空中架設狀態下之鋁電線(W)且在切斷位置(CT)附近夾住鋁電線(W)時，如圖1和2所示，支架部(4)的嵌合溝(4a)被嵌合在鋁電線(W)的頂部，在此狀態下，藉由間隔調整部(6)來調整為往縮小凸輪構件(5)和支架部(4)之間的間隔之方向，以便讓鋁電線(W)的下側部分嵌合到凸輪構件(5)的支撐槽(5a)內。結果，鋁電線(W)夾固在凸輪構件(5)和支架部(4)之間，並且處於緊線狀態。 Use the wire tightener (2) constructed as above, when cutting the aluminum wire (W) in the air erected state and clamp the aluminum wire (W) near the cutting position (CT), as shown in Figure 1 and As shown in 2, the fitting groove (4a) of the bracket part (4) is fitted to the top of the aluminum wire (W). In this state, the gap adjustment part (6) is used to adjust the cam member (5). ) And the direction of the interval between the bracket part (4) so that the lower part of the aluminum wire (W) fits into the support groove (5a) of the cam member (5). As a result, the aluminum wire (W) is sandwiched between the cam member (5) and the bracket part (4), and is in a tight wire state.
且，當藉由拉伸用工具(3)中的伸縮桿(3a)使緊線器(2)拉向接近切斷位置(CT)的方向(P)時，鋁電線(W)將在切斷位置(CT)附近往上彎曲。此時，對應到彎曲度，緊線器(2)在與拉伸用工具(3)的連結部(7)往上下方向來擺動，且凸輪構件(5)和支架部(4)位在遠離切斷位置(CT)的一側的端部下降。同時，鋁電線(W)的上側部分被用力地按壓在支架部(4)的嵌合溝(4a)的內表面上。 Also, when the tensioner (2) is pulled in the direction (P) approaching the cutting position (CT) by the extension rod (3a) in the stretching tool (3), the aluminum wire (W) will be cut Bend upward near the breaking point (CT). At this time, corresponding to the degree of curvature, the tensioner (2) swings up and down at the connection part (7) with the stretching tool (3), and the cam member (5) and the bracket part (4) are positioned far away The end on one side of the cutting position (CT) drops. At the same time, the upper part of the aluminum wire (W) is strongly pressed against the inner surface of the fitting groove (4a) of the bracket part (4).
如圖4(d)所示，嵌合溝(4a)在靠近切斷位置(CT)的一側的第一端部(4a1)處具有V字形剖面，如圖4(f)所示，在遠離切斷位置(CT)一側的第二端部(4a2)中，具有比第一端部(4a1)的V字形剖面更深的半圓形剖面。此外，如圖4(a)和4(e)所示，嵌合溝(4a)具有一剖面變化部(4c)，該剖面變化部 (4c)在包含該嵌合溝(4a)中遠側的第二端部(4a2)的至少一部分，沿著嵌合溝(4a)而逐漸接近遠側的第二端部(4a2)，從V字形剖面逐漸變為半圓形剖面。因此，在嵌合溝(4a)中接近切斷位置(CT)的部分，藉由讓構成V字形剖面的兩個表面分別用力地壓靠在鋁電線(W)的上側部分上，從寬度方向的兩側夾固鋁電線(W)就可以穩定地支撐鋁電線(W)，使得鋁電線(W)不會在鋁電線的軸向或寬度方向上移位。 As shown in Figure 4(d), the fitting groove (4a) has a V-shaped cross section at the first end (4a1) on the side close to the cutting position (CT), as shown in Figure 4(f), The second end (4a2) on the side away from the cutting position (CT) has a semicircular cross section that is deeper than the V-shaped cross section of the first end (4a1). In addition, as shown in Figures 4(a) and 4(e), the fitting groove (4a) has a cross-sectional change portion (4c), which (4c) At least a part of the distal second end (4a2) including the fitting groove (4a) is gradually approaching the distal second end (4a2) along the fitting groove (4a), from V The glyph profile gradually becomes a semicircular profile. Therefore, in the part of the fitting groove (4a) close to the cutting position (CT), the two surfaces constituting the V-shaped cross-section are pressed against the upper part of the aluminum wire (W) from the width direction. The aluminum wire (W) can be clamped on both sides of the aluminum wire to stably support the aluminum wire (W) so that the aluminum wire (W) will not shift in the axial or width direction of the aluminum wire.
在包含嵌合溝(4a)遠側的第二端部(4a2)的剖面變化部(4c)，具有隨著接近嵌合溝(4a)遠側的第二端部(4a2)，而讓嵌合溝(4a)之剖面從V字形剖面逐漸變為半圓形剖面之形狀。故，鋁電線(W)上側部分的支撐狀態，係隨著遠離切斷位置(CT)，藉由V字形剖面的兩個表面，從由在寬度方向兩側以兩個點被支撐的狀態平滑地變化到由半圓形剖面的彎曲面在寬度方向上以寬接觸面支撐的狀態。因此，即使在接近嵌合溝(4a)的遠側的第二端部(4a2)的部分中，也可以抑制在該軸向和寬度方向上的位移，同時可穩定地支撐鋁電線(W)。 The cross-sectional change portion (4c) including the second end (4a2) on the distal side of the fitting groove (4a) has the second end (4a2) on the distal side of the fitting groove (4a), allowing the insertion The cross section of Hegou (4a) gradually changes from a V-shaped cross section to a semicircular cross section. Therefore, the support state of the upper part of the aluminum wire (W) is as far away from the cutting position (CT), and the two surfaces of the V-shaped cross-section are smooth from the state supported by two points on both sides in the width direction. The ground changes to a state where the curved surface of the semicircular cross-section is supported by a wide contact surface in the width direction. Therefore, even in the portion close to the second end (4a2) on the distal side of the fitting groove (4a), the displacement in the axial and width directions can be suppressed, and the aluminum wire (W) can be stably supported at the same time .
此外，鋁電線(W)在切斷位置(CT)向上彎曲狀態下，由於嵌合溝(4a)之遠側的第二端部(4a2)係位於第一端部(4a1)下方，所以鋁電線(W)的上側端部會受到最用力的按壓。然而，遠側的第二端部(4a2)具有半圓形剖面，所以即使鋁電線(W)的上側端部被用力按壓在嵌合溝(4a)上，也會利用在嵌合溝(4a)的遠側的第二端部的半圓形剖面的彎曲面，在寬度方向上將力量分散到寬的接觸面上且加以支撐。 In addition, when the aluminum wire (W) is bent upward at the cutting position (CT), the second end (4a2) on the far side of the fitting groove (4a) is located below the first end (4a1). The upper end of the wire (W) will be pressed hardest. However, the distal second end (4a2) has a semicircular cross section, so even if the upper end of the aluminum wire (W) is pressed against the fitting groove (4a), it will be used in the fitting groove (4a). The curved surface of the semicircular cross-section of the second distal end of) disperses the force on the wide contact surface and supports it in the width direction.
結果，鋁電線(W)被穩定地支撐，使其在支架部(4)之嵌合溝(4a)的整個長度上不會在軸向和寬度方向上移位，且由於鋁電線(W)被按壓在嵌合溝(4a)的遠側之第二端部，所以可防止鋁電線(W)的包覆構件受到破損或損壞。 As a result, the aluminum wire (W) is stably supported so that it does not shift in the axial and width directions over the entire length of the fitting groove (4a) of the bracket portion (4), and the aluminum wire (W) It is pressed on the second end of the distal side of the fitting groove (4a), so that the covering member of the aluminum wire (W) can be prevented from being damaged or damaged.
此外，在該實施例的支架部(4)中，如圖4(a)和(f)所示，該支架部(4)在嵌合溝(4a)中遠離切斷位置的一側上的第二端部的邊緣為倒角且形成一倒角部分(4d)。因此，當以緊線器(2)夾固鋁電線(W)並將其拉到切斷位置(CT)時，即使鋁電線(W)的上側部分被按壓在遠離嵌合溝(4a)的切斷位置(CT)一側的第二端部(4a2)的邊緣上，該力量也會藉由該邊緣之倒角部分(4d)所形成的寬接觸面而分散。因此，可確實地防止或抑制因鋁電線(W)與嵌合溝(4a)的邊緣的接觸而讓鋁電線(W)的包覆構件受到破損或損壞。 In addition, in the bracket portion (4) of this embodiment, as shown in Figures 4(a) and (f), the bracket portion (4) is located on the side away from the cutting position in the fitting groove (4a) The edge of the second end is chamfered and forms a chamfered portion (4d). Therefore, when the aluminum wire (W) is clamped with the wire tensioner (2) and pulled to the cutting position (CT), even if the upper part of the aluminum wire (W) is pressed away from the fitting groove (4a) On the edge of the second end (4a2) on the side of the cutting position (CT), the force is also distributed by the wide contact surface formed by the chamfered portion (4d) of the edge. Therefore, it is possible to reliably prevent or suppress damage or damage to the covering member of the aluminum wire (W) due to the contact between the aluminum wire (W) and the edge of the fitting groove (4a).
除此之外，於本實施例上，鋁電線(W)具有一剖面變化部(4c)，該剖面變化部(4c)係根據粗細度等條件，當鋁電線(W)被拉到切斷位置(CT)時，嵌合溝(4a)具有與彎曲度相對應的形狀。具體而言，在上述實施例的構造中，為了對應於鋁電線(W)的彎曲度，如圖(4a)所示，嵌合溝中的第二端部(4a2)的半圓形剖面，在形成為比第一端部(4a1)的V字形剖面的深度更深之構造中，從相對於剖面變化部(4c)中V字形剖面的底部延伸的線(4e)的V字形剖面，逐漸變化為半圓形剖面的部分的底部延伸的線(4e)之角度θ1，係基於在鋁電線(W)被拉到切斷位置(CT)的狀態下之鋁電線(W)的彎曲度來設定。因此，當鋁電線(W)被拉向切斷位置(CT)時，雖鋁電線(W)在向上彎曲狀態下鋁電線(W)被按壓在支架部(4)上，但鋁電線(W)按壓於支架部(4)的力量係可被分散且支撐在整個剖面變化部。此結果，可確實地防止讓力量集中在嵌合溝(4a)的遠側的第二端部上，且可更確實地抑制在該嵌合溝(4a)的遠側的第二端部(4a2)的鋁電線(W)的包覆構件受到破損或損壞。 In addition, in this embodiment, the aluminum wire (W) has a cross-sectional change part (4c), the cross-sectional change part (4c) is based on conditions such as thickness, when the aluminum wire (W) is pulled to cut In the position (CT), the fitting groove (4a) has a shape corresponding to the curvature. Specifically, in the configuration of the above-mentioned embodiment, in order to correspond to the curvature of the aluminum wire (W), as shown in Figure (4a), the semicircular cross section of the second end (4a2) in the fitting groove, In a structure formed to be deeper than the depth of the V-shaped cross-section of the first end (4a1), the V-shaped cross-section of the line (4e) extending from the bottom of the V-shaped cross-section in the cross-sectional change portion (4c) gradually changes The angle θ1 of the line (4e) extending from the bottom of the semicircular section is set based on the bending degree of the aluminum wire (W) when the aluminum wire (W) is pulled to the cutting position (CT) . Therefore, when the aluminum wire (W) is pulled to the cutting position (CT), although the aluminum wire (W) is pressed on the bracket part (4) in the upward bending state, the aluminum wire (W) ) The force system pressing on the bracket part (4) can be dispersed and supported in the entire section change part. As a result, it is possible to reliably prevent the force from being concentrated on the distal second end of the fitting groove (4a), and it is possible to more reliably restrain the distal second end of the fitting groove (4a) ( The covering member of the aluminum wire (W) of 4a2) is damaged or damaged.
此外，在本實施例的緊線器(2)中，支架部(4)係以可拆卸方式安裝在間隔調整部(6)的固定部(6b)上。因此，可以更換為具有與鋁電線(W)的粗細度相對應的嵌合溝(4a)之支架(4)。例如，在圖2至圖3所示的緊線器(2)中，雖32平方鋁電線(W)用的支架部(4)係安裝到間隔調整部(6)的固定部(6b)，但也可將圖6所示的120平方鋁電線支架部(4)以可裝卸方式 安裝到該固定部(6b)作為對應於粗的鋁電線的支架部來取代此支架部(4)。 In addition, in the tensioner (2) of this embodiment, the bracket part (4) is detachably mounted on the fixing part (6b) of the interval adjusting part (6). Therefore, it can be replaced with a bracket (4) having a fitting groove (4a) corresponding to the thickness of the aluminum wire (W). For example, in the tensioner (2) shown in Figures 2 to 3, although the bracket part (4) for the 32 square aluminum wire (W) is installed to the fixed part (6b) of the interval adjustment part (6), However, the 120 square aluminum wire bracket (4) shown in FIG. 6 can be detachably mounted to the fixed portion (6b) as a bracket corresponding to the thick aluminum wire instead of the bracket (4).
此外，圖6所示的120平方鋁電線用的支架部(4)，與圖4所示的32平方鋁電線用的支架部(4)相比，以正好相對應的電線的粗細度，嵌合溝(4a)之形狀略有不同，至於其他部分，若具有共同的構造，則也可以將其更換為上述的32平方用的支架部(4)。 In addition, the bracket part (4) for the 120 square aluminum wire shown in FIG. 6 is embedded with the thickness of the wire exactly corresponding to the bracket part (4) for the 32 square aluminum wire shown in FIG. The shape of the joint groove (4a) is slightly different. As for other parts, if they have a common structure, they can also be replaced with the above-mentioned 32 square bracket part (4).
此外，在本實施例的緊線器(2)中，凸輪構件(5)和支架部(4)係以可裝卸方式安裝在間隔調整部(6)上。因此，不僅可以更換為具有與鋁電線(W)的粗細度相對應的嵌合溝(4a)之支架(4)，也可以更換為具有尖釘(突起)之凸輪構件(5)和支架部(4)，該尖釘(突起)適合於夾固由鋁電線(W)以外的材質的電線，例如具有銅線的線。其結果，廣泛使用緊線器(2)。 In addition, in the tensioner (2) of this embodiment, the cam member (5) and the bracket portion (4) are detachably mounted on the interval adjusting portion (6). Therefore, not only can it be replaced with a bracket (4) with a fitting groove (4a) corresponding to the thickness of the aluminum wire (W), but also with a cam member (5) and a bracket with spikes (protrusions) (4) The spike (protrusion) is suitable for clamping wires made of materials other than aluminum wires (W), such as wires with copper wires. As a result, the tightening device (2) is widely used.
在具備有本實施例的緊線器(2)的活線排序工具(1)中，藉由如上所述構成之一對緊線器(2)，在切斷位置(CT)之兩側夾固鋁電線(W)，藉由拉伸用工具(3)的伸縮桿(3a)將一對緊線器(2)分別往接近鋁電線(W)的切斷位置(CT)的方向上拉伸，藉此，鋁電線(W)就可容易地從兩側將鋁電線(W)拉到切斷位置(CT)。同時，可以防止在鋁電線(W)中的切斷位置(CT)的兩側部分由緊線器(2)所夾固的部分中的鋁電線(W)的包覆構件受到破損或損壞。 In the live thread sorting tool (1) equipped with the thread tensioner (2) of this embodiment, a pair of thread tensioners (2) are formed as described above and clamped on both sides of the cutting position (CT) To fix the aluminum wire (W), use the extension rod (3a) of the stretching tool (3) to pull the pair of wire tensioners (2) to the direction close to the cutting position (CT) of the aluminum wire (W). By this, the aluminum wire (W) can be easily pulled to the cutting position (CT) from both sides. At the same time, it is possible to prevent the covering member of the aluminum wire (W) in the portion clamped by the wire tensioner (2) on both sides of the cutting position (CT) in the aluminum wire (W) from being damaged or damaged.
本發明係可廣泛用於鋁電線用的緊線器及使用緊線器之活線排序工具，並且可防止當鋁電線被夾固並拉到切斷位置時讓鋁電線的包覆構件受到損壞。 The invention can be widely used in wire tightening devices for aluminum wires and live wire sequencing tools using wire tightening devices, and can prevent the aluminum wires from being damaged when the aluminum wires are clamped and pulled to the cutting position .
