Description

本発明は、電線の電気的特性を測定する際に用いられる電気測定補助具に係り、特に、コネクタなどに設けられた電線挿入穴に挿入された電線の電気的特性測定に有用な電気測定補助具に関する。   The present invention relates to an electric measurement auxiliary tool used when measuring electric characteristics of electric wires, and more particularly, electric measurement auxiliary useful for measuring electric characteristics of electric wires inserted into electric wire insertion holes provided in connectors and the like. Concerning ingredients.

従来から、電線に流れる電気の特性、例えば、通電の有無や、電圧値、電流値などを測定するために種々の電気測定器が提案されている。このような電気測定器は、電気測定器本体と電線に接触するための接触棒や接触クリップなどを備えている（例えば、下記特許文献１、２など）。そして接触棒等を電線に接触させることにより電気的特性の測定を行う。   Conventionally, various electric measuring instruments have been proposed for measuring the characteristics of electricity flowing in an electric wire, such as the presence / absence of energization, voltage value, current value, and the like. Such an electric measuring device is provided with a contact rod or a contact clip for contacting the electric measuring device main body and the electric wire (for example, Patent Documents 1 and 2 below). Then, electrical characteristics are measured by bringing a contact rod or the like into contact with the electric wire.

測定対象の電線の中には、昇降機の配線中継コネクタに接続された電線などもある。このような電線は、コネクタに設けられた電線挿入穴に挿入されており、電線挿入穴から突出している部分には、絶縁性の被膜が施されている。したがって、このような電線の電気的特性を測定する場合は、電線のうち、被膜が施されていない部分、電線挿入穴に挿入されている部分に電気測定器の接触棒などを接触させなければならない。   Among the electric wires to be measured, there are electric wires connected to the wiring relay connector of the elevator. Such an electric wire is inserted into an electric wire insertion hole provided in the connector, and an insulating film is applied to a portion protruding from the electric wire insertion hole.

しかしながら、通常、電線挿入穴は、電線の径に応じて形成されており、電線と電線挿入穴との間隙は小さいことが多い。一方、汎用的な電気測定器の接触棒やクリップなどは、電線挿入穴内の電線に接触することが考慮されておらず、耐久性などを考慮して比較的大きく形成されている。したがって、このような接触棒やクリップを電線挿入穴と電線との間隙に挿入することは困難であり、無理に挿入しようとすると、電線や電線挿入穴を傷つけることがある。電気測定器の接触棒などの形状を小さくすることも考えられるが、電気測定器そのものを電線挿入穴内の電線という比較的限られた用途のために改良することは、コストや手間などの観点から望ましくない。   However, the electric wire insertion hole is usually formed according to the diameter of the electric wire, and the gap between the electric wire and the electric wire insertion hole is often small. On the other hand, contact bars and clips of general-purpose electrical measuring instruments are not considered to contact the electric wires in the electric wire insertion holes, and are formed relatively large in consideration of durability and the like. Therefore, it is difficult to insert such a contact rod or clip into the gap between the electric wire insertion hole and the electric wire, and if the insertion is forced, the electric wire or the electric wire insertion hole may be damaged. Although it is conceivable to reduce the shape of the contact rod of the electric measuring device, it is possible to improve the electric measuring device itself for a relatively limited use of the electric wire in the electric wire insertion hole from the viewpoint of cost and labor. Not desirable.

そこで、本発明では、電線挿入穴に挿入された電線についても簡易に電気的特性測定ができる電気測定補助具を提供することを目的とする。   Therefore, an object of the present invention is to provide an electrical measurement auxiliary tool that can easily measure electrical characteristics of an electric wire inserted into an electric wire insertion hole.

本発明の電気測定補助具は、コネクタの電線挿入穴に挿入された電線の電気的特性測定を補助する電気測定補助具であって、操作者が把持する把持部と、把持部から突出して設けられ、電線と電線挿入穴との間隙に挿入可能な径の導電性針状部材である接触針と、接触針と電気的に接続され、電気的特性を測定する電気測定器に接続可能な接続部と、を有することを特徴とする。   The electrical measurement auxiliary tool of the present invention is an electrical measurement auxiliary tool that assists in measuring the electrical characteristics of the electric wire inserted into the electric wire insertion hole of the connector, and is provided with a gripping portion that is gripped by an operator and protruding from the gripping portion. A contact needle that is a conductive needle-shaped member having a diameter that can be inserted into the gap between the electric wire and the electric wire insertion hole, and a connection that is electrically connected to the contact needle and can be connected to an electric measuring instrument that measures the electrical characteristics. And a portion.

好適な態様では、さらに、接触針を電線挿入穴に挿入したときに電線挿入穴の外側に延びる電線に、電気測定補助具を取り付ける電線取付具を有する。望ましくは、電線取付具は、電線を挟持する方向に弾性体により付勢された一対の挟持部材を有する。   In a preferred embodiment, the electric wire attaching tool further includes an electric measuring tool for attaching an electric measurement auxiliary tool to the electric wire extending outside the electric wire insertion hole when the contact needle is inserted into the electric wire insertion hole. Desirably, an electric wire fixture has a pair of clamping member urged | biased by the elastic body in the direction which clamps an electric wire.

他の好適な態様では、接触針の先端が電線に接触する方向に、接触針を付勢する弾性部材を有する。他の好適な態様では、接触針の先端は他のところに比べて大径である。他の好適な態様では、接触針は、電線に向かって傾斜している。   In another preferred aspect, the elastic member biases the contact needle in a direction in which the tip of the contact needle contacts the electric wire. In another preferred embodiment, the tip of the contact needle has a larger diameter than elsewhere. In another preferred embodiment, the contact needle is inclined toward the electric wire.

本発明によれば、接触針が、電線挿入穴と電線との間隙に挿入可能であるため、電気挿入穴の内部の電線と接触針とを容易に接触できる。そのため、電線挿入穴に挿入された電線についても簡易に電気的特性測定ができる。   According to the present invention, since the contact needle can be inserted into the gap between the electric wire insertion hole and the electric wire, the electric wire inside the electric insertion hole and the contact needle can be easily contacted. Therefore, electrical characteristics can be easily measured for the electric wires inserted into the electric wire insertion holes.

以下、本発明の実施の形態について図面を参照して説明する。図１に本発明の実施の形態である電気測定補助具１０の斜視図を、図２に図１におけるＡ−Ａ断面図を示す。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an electrical measurement auxiliary tool 10 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA in FIG.

この電気測定補助具１０は、電線の電気測定を行う場合に用いられる補助具で、特に、電気コネクタに設けられた電線挿入穴に電線を挿入した状態のままで測定する場合に用いられる。   This electrical measurement auxiliary tool 10 is an auxiliary tool used when performing electrical measurement of electric wires, and is particularly used when measuring with the electric wires inserted into the electric wire insertion holes provided in the electric connector.

電気測定補助具１０は、操作者が把持する把持部１２と、電線を保持する電線取付具１６、および、電線に接触する接触針１４に大別される。   The electrical measurement auxiliary tool 10 is roughly classified into a grip portion 12 that an operator grips, an electric wire fixture 16 that holds an electric wire, and a contact needle 14 that contacts the electric wire.

把持部１２は、操作者が把持するための略半円筒形状の内空部材で、その内部には、接触針１４の一部や、電気測定器との接続部２２などが設けられている。把持部１２の側面の途中には、接触針１４の操作レバー４２を収納するために突出部２０が形成されている。この突出部２０は、比較的肉薄に形成されており、操作者の押圧により弾性変形可能となっている。   The grip portion 12 is a substantially semi-cylindrical hollow member for gripping by an operator, and a part of the contact needle 14, a connection portion 22 with an electric measuring instrument, and the like are provided therein. In the middle of the side surface of the gripping portion 12, a protruding portion 20 is formed to accommodate the operation lever 42 of the contact needle 14. The protrusion 20 is formed to be relatively thin and can be elastically deformed by an operator's pressing.

また、把持部１２の先端付近には、電線取付具１６が取り付けられている。電線取付具１６は、電気測定補助具１０を測定対象の電線に取り付けるもので、把持部１２と直交する方向に設けられた鋏状部材である。電線取付具１６は、支点３３を中心として交差して設けられた一対の挟持部材２４，２６を有している。この一対の挟持部材２４，２６は、圧縮バネ２８で接続されており、一対の挟持部材２４，２６が閉じる方向（図１におけるａ方向）に付勢されている。   An electric wire fixture 16 is attached near the tip of the grip portion 12. The electric wire attachment 16 attaches the electric measurement auxiliary tool 10 to the electric wire to be measured, and is a hook-shaped member provided in a direction orthogonal to the grip portion 12. The electric wire fixture 16 has a pair of clamping members 24 and 26 provided so as to intersect with each other about the fulcrum 33. The pair of clamping members 24 and 26 are connected by a compression spring 28, and are urged in a direction in which the pair of clamping members 24 and 26 close (a direction in FIG. 1).

接触針１４は、電線挿入穴に挿入された電線に接触するもので、後述する接続部２２とケーブル４６を介して電気的に接続されている。この接触針１４は、把持部１２から突出する針状部材である針部３４と、把持部１２内に収納される基部３８とに大別される。   The contact needle 14 is in contact with the electric wire inserted into the electric wire insertion hole, and is electrically connected via a connecting portion 22 and a cable 46 described later. The contact needle 14 is roughly divided into a needle part 34 that is a needle-like member protruding from the grip part 12 and a base part 38 that is accommodated in the grip part 12.

針部３４は、把持部１２の後端から突出する針状部材である。この針部３４は、電線と電線挿入穴との間隙にも挿入できるように十分に小さい径となっている。また、中間位置で角度がついており、電線に向かって傾斜している。針部先端３６は、電線に接触しやすいように、折り返されており、他の部分より大径となっている。   The needle part 34 is a needle-like member protruding from the rear end of the grip part 12. The needle portion 34 has a sufficiently small diameter so that it can be inserted into the gap between the electric wire and the electric wire insertion hole. Moreover, the angle is attached in the intermediate position and it inclines toward the electric wire. The needle tip 36 is folded back so as to be easily in contact with the electric wire, and has a larger diameter than other portions.

基部３８は、符号４０で示される支持位置４０で把持部１２に保持されており、基部３８に設けられた操作レバー４２を押圧することにより針部３４とともに支持位置４０を中心として可動できるようになっている。また、把持部１２の内側面に設けられた引張バネ４４により電線押圧方向（図面左側）に付勢されている。   The base portion 38 is held by the grip portion 12 at a support position 40 indicated by reference numeral 40, and can be moved around the support position 40 together with the needle portion 34 by pressing an operation lever 42 provided on the base portion 38. It has become. Moreover, it is urged | biased by the tension | pulling spring 44 provided in the inner surface of the holding part 12 in the electric wire press direction (drawing left side).

基部３８の後端には上述した針部３４が、先端にはケーブル４６が接続されている。このケーブル４６は、電気測定器と接続する接続部２２に接続されている。接続部２２は、電気的特性を測定する電気測定器（例えば、電圧計など）の計測棒が挿脱自在の穴である。この接続部２２に、計測棒を挿入することにより、電気測定器と接触針１４とが電気的に接続される。   The needle portion 34 described above is connected to the rear end of the base portion 38, and the cable 46 is connected to the tip end. This cable 46 is connected to the connection part 22 connected to the electrical measuring instrument. The connection part 22 is a hole through which a measuring rod of an electrical measuring instrument (for example, a voltmeter) for measuring electrical characteristics can be inserted and removed. By inserting a measuring rod into the connecting portion 22, the electrical measuring instrument and the contact needle 14 are electrically connected.

次に、この電気測定補助具１０を用いて、コネクタに取り付けられた電線の電気的特性の測定をする流れについて図３を用いて説明する。図３は、電気測定補助具１０を用いた電気的特性測定の状態を示す図である。   Next, the flow of measuring the electrical characteristics of the electric wire attached to the connector using the electrical measurement auxiliary tool 10 will be described with reference to FIG. FIG. 3 is a diagram illustrating a state of electrical characteristic measurement using the electrical measurement auxiliary tool 10.

電気的特性の測定対象である電線５４は、コネクタ５０に設けられた電線挿入穴５２に挿入されている。この電線５４のうち、電線挿入穴５２から突出した部分は、絶縁材料からなる被膜５６で覆われている。一方、電線挿入穴５２の内部に挿入されている部分は、被膜５６が剥離されている。したがって、電線５４の電気的特性を測定する場合、電線５４のうち電線挿入穴５２に挿入されている部分５８と電気測定器６０（例えば、電流計など）とを電気的に接続する必要がある。   An electric wire 54 that is a measurement target of electrical characteristics is inserted into an electric wire insertion hole 52 provided in the connector 50. A portion of the electric wire 54 that protrudes from the electric wire insertion hole 52 is covered with a coating 56 made of an insulating material. On the other hand, the coating 56 is peeled off from the portion inserted into the electric wire insertion hole 52. Therefore, when measuring the electrical characteristics of the electric wire 54, it is necessary to electrically connect a portion 58 of the electric wire 54 inserted into the electric wire insertion hole 52 and an electric measuring instrument 60 (for example, an ammeter). .

通常、電気測定器６０には、測定対象の電線５４に接触するための金属棒６４（計測棒）が設けられている。しかし、この計測棒６４は、耐久性などを考慮して比較的大径となっている。したがって、この計測棒６４を、電線挿入穴５２とこれに挿入されている電線５４との間隙に挿入することは困難な場合が多く、無理に計測棒６４を挿入した場合、電線５４や電線挿入穴５２を傷つけることが多い。   Usually, the electric measuring instrument 60 is provided with a metal bar 64 (measuring bar) for contacting the electric wire 54 to be measured. However, the measuring rod 64 has a relatively large diameter in consideration of durability and the like. Therefore, it is often difficult to insert the measuring rod 64 into the gap between the electric wire insertion hole 52 and the electric wire 54 inserted therein. When the measuring rod 64 is forcibly inserted, the electric wire 54 or the electric wire is inserted. The hole 52 is often damaged.

そこで、このような電線５４の電気的特性を測定する場合は、上述した電気測定補助具１０を用いる。操作者は、まず、把持部１２を手に持ち、測定したい電線５４近傍に電気測定補助具１０を持ってくる。   Therefore, when measuring the electrical characteristics of such an electric wire 54, the electrical measurement auxiliary tool 10 described above is used. First, the operator holds the grip portion 12 in his hand and brings the electrical measurement auxiliary tool 10 near the electric wire 54 to be measured.

そして、接触針１４の針部先端３６を電線挿入穴に挿入する。このとき、操作者は突出部２０を押圧する。これにより、把持部１２内部の操作レバー４２を押圧され、針部先端３６が引張バネ４４の弾性力に抗して、電線５４と反対側（図２における右側）に移動する。その状態で、針部３４を確実に電線挿入穴５２に挿入すれば、突出部２０への押圧を解除する。これにより、針部先端３６は、引張バネ４４の弾性力より電線５４方向（図２における左側）に付勢される。   Then, the needle tip 36 of the contact needle 14 is inserted into the wire insertion hole. At this time, the operator presses the protruding portion 20. As a result, the operation lever 42 inside the grip portion 12 is pressed, and the tip end 36 of the needle moves against the elastic force of the tension spring 44 to the opposite side (right side in FIG. 2). In this state, if the needle portion 34 is securely inserted into the electric wire insertion hole 52, the pressure on the protruding portion 20 is released. As a result, the needle tip 36 is biased in the direction of the electric wire 54 (left side in FIG. 2) by the elastic force of the tension spring 44.

ここで、針部３４は、十分に小さい径で形成されているため、電線５４や電線挿入穴５２に過大な負荷をかけることなく挿入することができる。また、針部３４は引張バネ４４により電線５４方向に付勢されるとともに、針部先端３６が大径となっているため、針部先端３６が電線５４に接触しやすくなっている。さらに、針部３４は電線５４に向かって傾斜しているため、より、針部先端３６が電線５４に接触しやすくなっている。   Here, since the needle part 34 is formed with a sufficiently small diameter, the needle part 34 can be inserted without applying an excessive load to the electric wire 54 and the electric wire insertion hole 52. Further, the needle portion 34 is urged in the direction of the electric wire 54 by the tension spring 44 and the needle portion distal end 36 has a large diameter, so that the needle portion distal end 36 is easily in contact with the electric wire 54. Furthermore, since the needle portion 34 is inclined toward the electric wire 54, the needle portion tip 36 is more likely to come into contact with the electric wire 54.

また、挿入の際には、突出部２０を押圧することにより、針部先端３６と電線５４とを離しておくことができる。これにより、挿入の際に、針部先端３６で電線５４を擦ることがなく、電線５４の破損を防止できる。   Further, at the time of insertion, the needle tip 36 and the electric wire 54 can be separated by pressing the protrusion 20. Thereby, at the time of insertion, the electric wire 54 is not rubbed by the needle tip 36, and the electric wire 54 can be prevented from being damaged.

針部先端３６を電線５４に接触させることができれば、電気測定補助具１０を電線取付具１６で電線に取り付ける。これは、次の手順で行う。まず、一対の挟持部材２４，２６を手で開方向（図１におけるｂ方向）に押し広げて挟持部材２４，２６の開角度を広げる。開角度を広げた状態で、挟持部材２４，２６を電線５４に押し当てる。そして、挟持部材２４，２６から手を外せば、一対の挟持部材２４，２６には、圧縮バネ２８により閉方向（図１におけるａ方向）の力がかかる。これにより、一対の挟持部材２４，２６は電線５４を挟持した状態となり、電気測定補助具１０は電線５４に取り付けられる。   If the needle tip 36 can be brought into contact with the electric wire 54, the electric measurement auxiliary tool 10 is attached to the electric wire with the electric wire fixture 16. This is done by the following procedure. First, the pair of sandwiching members 24 and 26 are spread by hand in the opening direction (direction b in FIG. 1) to widen the opening angle of the sandwiching members 24 and 26. The clamping members 24 and 26 are pressed against the electric wire 54 in a state where the opening angle is widened. When the hands are removed from the clamping members 24 and 26, a force in the closing direction (a direction in FIG. 1) is applied to the pair of clamping members 24 and 26 by the compression spring 28. As a result, the pair of clamping members 24 and 26 sandwich the electric wire 54, and the electrical measurement auxiliary tool 10 is attached to the electric wire 54.

次に、電気測定器６０の計測棒６４を、接続部２２に挿入する。これにより計測棒６４と接触針１４とが電気的に接続、ひいては、電線５４と電気測定器６０とが電気的に接続される。これにより、電気測定器６０で電線５４の電気的特性測定が可能となる。また、この計測棒６４を挿入する際には、電気測定補助具１０は、電線５４に取り付けられている。したがって、計測棒６４の挿入操作の際には、操作者は電気測定補助具１０から両手を離してもよく、より簡易に計測棒６４の挿入操作ができる。つまり、電線取付具１６を設けることにより、簡易に電気測定器６０との接続操作ができる。   Next, the measuring rod 64 of the electrical measuring instrument 60 is inserted into the connecting portion 22. As a result, the measuring rod 64 and the contact needle 14 are electrically connected. As a result, the electric wire 54 and the electric measuring instrument 60 are electrically connected. As a result, it is possible to measure the electric characteristics of the electric wire 54 with the electric measuring instrument 60. Further, when inserting the measuring rod 64, the electrical measurement auxiliary tool 10 is attached to the electric wire 54. Therefore, when inserting the measuring rod 64, the operator may remove both hands from the electrical measurement auxiliary tool 10, and the measuring rod 64 can be inserted more easily. That is, by providing the electric wire fixture 16, a connection operation with the electric measuring device 60 can be easily performed.

なお、計測棒６４を挿入した時点では、接触針１４の針部先端３６と電線５４との接触が不十分となっている場合がある。これは、電線取付具１６を電線５４に取り付ける操作をしている途中で、電気測定補助具１０全体の姿勢が動くことがあるからである。その場合は、適宜、電気測定補助具１０の姿勢を手で調整し、確実に針部先端３６と電線５４とを接触させる。上述したように針部３４は、引張バネ４４により電線５４方向に付勢されているため、多少の姿勢調整で針部先端３６を電線５４に接触させることができる。   Note that when the measuring rod 64 is inserted, the contact between the needle tip 36 of the contact needle 14 and the electric wire 54 may be insufficient. This is because the posture of the electrical measurement auxiliary tool 10 as a whole may move during the operation of attaching the wire fixture 16 to the wire 54. In that case, the posture of the electrical measurement auxiliary tool 10 is adjusted by hand as appropriate, and the needle tip 36 and the electric wire 54 are reliably brought into contact with each other. As described above, since the needle portion 34 is urged in the direction of the electric wire 54 by the tension spring 44, the needle portion tip 36 can be brought into contact with the electric wire 54 with a slight attitude adjustment.

電気的特性の測定ができれば、再度、一対の挟持部材２４，２６を手で開方向に押し広げ、電線５４から電線取付具１６を取り外す。そして、把持部１２の突出部２０を手で押し、針部３４を引張バネ４４の付勢力に抗して電線５４から離れる方向に可動させる。そして、針部３４と電線５４とが離れた状態で、電気測定補助具１０全体を持ち上げ、電線挿入穴５２から針部３４を抜き取る。このように、突出部２０を押圧し、針部３４と電線５４とを離してから、針部３４を引き抜くことにより、針部先端３６による電線５４の引っ掻きを防止できる。   If the electrical characteristics can be measured, the pair of holding members 24 and 26 are again spread in the opening direction by hand, and the wire fitting 16 is removed from the wire 54. And the protrusion part 20 of the holding part 12 is pushed by hand, and the needle part 34 is moved in the direction away from the electric wire 54 against the urging force of the tension spring 44. Then, with the needle portion 34 and the electric wire 54 separated from each other, the entire electrical measurement auxiliary tool 10 is lifted and the needle portion 34 is extracted from the electric wire insertion hole 52. In this manner, by pressing the protruding portion 20 and separating the needle portion 34 and the electric wire 54, the needle portion 34 is pulled out, whereby the electric wire 54 can be prevented from being scratched by the needle tip 36.

以上、説明したように、本実施の形態の電気測定補助具１０を用いれば、簡易に電線挿入穴５２に挿入された電線５４の電気的特性を測定することができる。また、測定時に、電線５４や電線挿入穴５２を傷つけることがない。さらに、接触針１４を簡単な操作で可動できる構成としているため、電線挿入穴５２への挿脱時に、接触針１４による電線５４の引っ掻きを防止できる。   As described above, by using the electrical measurement auxiliary tool 10 of the present embodiment, it is possible to easily measure the electrical characteristics of the electric wire 54 inserted into the electric wire insertion hole 52. Moreover, the electric wire 54 and the electric wire insertion hole 52 are not damaged at the time of measurement. Furthermore, since the contact needle 14 is configured to be movable by a simple operation, it is possible to prevent the electric wire 54 from being scratched by the contact needle 14 when being inserted into and removed from the electric wire insertion hole 52.

なお、電気測定補助具１０を構成する各部材の形状、材質などは、その機能を損なわない範囲であれば、適宜、変更してもよい。   In addition, you may change suitably the shape, material, etc. of each member which comprises the electrical measurement auxiliary tool 10 as long as the function is not impaired.
