Description

本発明は、圧接端子に関する。   The present invention relates to a press contact terminal.

従来、一対の挟持片の間に被覆電線が挿通されることにより一対の挟持片が絶縁被覆を切り込み、その内側の芯線に接触する圧接端子が知られている。   2. Description of the Related Art Conventionally, a press contact terminal is known in which a pair of sandwiching pieces cuts an insulating coating by inserting a covered electric wire between the pair of sandwiching pieces and contacts an inner core wire.

このような圧接端子は、時間の経過等により一対の挟持片間の間隔が広がる方向に各挟持片が変形し、電線を圧接する際の接触圧が弱くなるおそれがある。   Such a press contact terminal may be deformed in a direction in which the interval between the pair of sandwich pieces is widened with the passage of time or the like, and the contact pressure at the time of pressing the electric wire may be weakened.

そこで、特許文献1に示すように、圧接端子を雄形圧接端子と雌形圧接端子とから構成し、雌形圧接端子の両側に形成されたカール部の先端と圧接部との間隙に雄形圧接端子の圧接部を受け入れるようにすることが考えられた。このようにすれば、雄形圧接端子の圧接部は左右から狭圧されてU字状スロットを強制圧縮し、雄形圧接端子がカール部の先端を拡幅することで雌形圧接端子のU字状スロットが強制圧縮される強制狭着機構を構成することができる。   Therefore, as shown in Patent Document 1, the press contact terminal is composed of a male press contact terminal and a female press contact terminal, and the male contact is formed in the gap between the tip of the curl portion and the press contact portion formed on both sides of the female press contact terminal. It was considered to accept the pressure contact portion of the pressure contact terminal. In this way, the pressure contact portion of the male pressure contact terminal is narrowed from the left and right to forcibly compress the U-shaped slot, and the male pressure contact terminal widens the front end of the curled portion, thereby the U shape of the female pressure contact terminal. A forced constriction mechanism in which the slot-like slot is forcibly compressed can be configured.

ところで、上記特許文献1の構成は、雄形圧接端子の圧接部については、カール部の先端で直接的に挟圧しているため、時間が経過しても比較的強い力で圧接されているのに対して、雌形圧接端子の圧接部については、雄形圧接端子がカール部の先端を拡幅する力の反動により圧接部を圧縮する構成であり、圧接部を直接的に挟圧する場合と比較すると時間の経過により圧接部と電線との接触圧が弱くなって(スロット径が広くなって電線との圧接部分が緩み)接触不良が生じることが懸念される。   By the way, since the structure of the said patent document 1 is directly clamped by the front-end | tip of a curl part about the press-contact part of a male press-contact terminal, it is press-contacted by comparatively strong force even if time passes. On the other hand, with regard to the pressure contact portion of the female pressure contact terminal, the male pressure contact terminal is configured to compress the pressure contact portion by the reaction of the force that widens the tip of the curled portion, and compared with the case where the pressure contact portion is directly pinched. Then, with the passage of time, the contact pressure between the press contact portion and the electric wire becomes weak (the slot diameter becomes wide and the press contact portion with the electric wire becomes loose), and there is a concern that contact failure may occur.

本発明は上記のような事情に基づいて完成されたものであって、電線との接触不良を防止することが可能な圧接端子を提供することを目的とする。   This invention is completed based on the above situations, Comprising: It aims at providing the press-contact terminal which can prevent the poor contact with an electric wire.

本発明の圧接端子は、一対の第1挟持片の間に電線が挿通されて圧接される第1圧接端子と、一対の第2挟持片の間に電線が挿通されて圧接される第2圧接端子とを前記第1挟持片と前記第2挟持片とが重なるように組み合わせて構成される圧接端子であって、前記第1圧接端子には、前記一対の第2挟持片間の間隔が広がる方向への前記第2挟持片の変形を規制する第1変形規制部が設けられるとともに、前記第2圧接端子には、前記一対の第1挟持片間の間隔が広がる方向への前記第1挟持片の変形を規制する第2変形規制部が設けられているところに特徴を有する。   The press contact terminal of the present invention includes a first press contact terminal in which an electric wire is inserted and pressed between a pair of first clamping pieces, and a second press contact in which the electric wire is inserted and pressed between a pair of second holding pieces. A press contact terminal configured such that the first sandwiching piece and the second sandwiching piece overlap with each other, and the first press contact terminal has a wide gap between the pair of second sandwiching pieces. A first deformation restricting portion for restricting deformation of the second sandwiching piece in the direction is provided, and the second press-contact terminal includes the first sandwiching in a direction in which a gap between the pair of first sandwiching pieces is widened. It is characterized in that a second deformation restricting portion for restricting the deformation of the piece is provided.

本構成によれば、第1圧接端子の第1変形規制部により一対の第2挟持片間の間隔が広がる方向への第2挟持片の変形が規制されるため、電線と第2挟持片との間の接触圧が弱くなることによる接触不良を防止することができる。また、第2圧接端子の第2変形規制部により一対の第1挟持片間の間隔が広がる方向への第1挟持片の変形が規制されるため、電線と第1挟持片との間の接触圧が弱くなることによる接触不良を防止することができる。よって、電線と圧接端子との間の接触不良を防止することができる。   According to this configuration, since the deformation of the second clamping piece in the direction in which the interval between the pair of second clamping pieces widens is regulated by the first deformation regulating portion of the first pressure contact terminal, the electric wire and the second clamping piece It is possible to prevent contact failure due to weakening of the contact pressure between the two. Further, since the deformation of the first clamping piece in the direction in which the distance between the pair of first clamping pieces is widened is regulated by the second deformation regulating portion of the second pressure contact terminal, the contact between the electric wire and the first clamping piece. Contact failure due to weak pressure can be prevented. Therefore, poor contact between the electric wire and the press contact terminal can be prevented.

上記構成に加えて以下の構成を有すればより好ましい。
(1)前記第1変形規制部及び前記第2変形規制部は、前記各挟持片の側縁部から前記挟持片が重なる側に突出している。
このようにすれば、圧接端子の構成を簡素化することができる。
It is more preferable to have the following configuration in addition to the above configuration.
(1) The said 1st deformation | transformation control part and the said 2nd deformation | transformation control part protrude in the side where the said clamping piece overlaps from the side edge part of each said clamping piece.
In this way, the configuration of the press contact terminal can be simplified.

(2)前記第1変形規制部及び前記第2変形規制部は、前記挟持片の側縁部から前記挟持片の面に沿う方向に折り返す折り返し片である。
このようにすれば、第1及び第2圧接端子のうちの一方の折り返し片の内側に第1及び第2圧接端子のうちの他方の挟持片を保持することが可能になる。
(2) The first deformation restricting portion and the second deformation restricting portion are folded pieces that are folded back in a direction along a surface of the sandwiching piece from a side edge portion of the sandwiching piece.
If it does in this way, it will become possible to hold | maintain the other clamping piece of the 1st and 2nd press-contact terminal inside one folding piece of the 1st and 2nd press-contact terminal.

(3)前記挟持片に設けられた折り返し片は、当該挟持片に重ねられた挟持片の面に当接している。
このようにすれば、第1及び第2圧接端子間の接触面積を大きくすることができるため、電気抵抗を少なくすることが可能になる。
(3) The folded piece provided on the sandwiching piece is in contact with the surface of the sandwiching piece superimposed on the sandwiching piece.
In this way, since the contact area between the first and second press contact terminals can be increased, the electrical resistance can be reduced.

(4)前記第1変形規制部及び前記第2変形規制部は、前記各挟持片の基端部であって、当該挟持片に重ねられた挟持片における先端側寄りの位置に形成されている。
このようにすれば、第1変形規制部及び第2変形規制部を挟持片の基端部に形成することで比較的挟持片の変形による影響を受けないようにすることができる。また、この挟持片を重ねられた挟持片における先端側寄りの位置とすることで、重ねられた挟持片について変形が生じやすい先端側の変形を有効に防止することができる。
(4) The first deformation restricting portion and the second deformation restricting portion are proximal end portions of the respective holding pieces, and are formed at positions closer to the distal end side of the holding pieces stacked on the holding pieces. .
If it does in this way, it can avoid being comparatively influenced by the deformation | transformation of a clamping piece by forming a 1st deformation | transformation control part and a 2nd deformation control part in the base end part of a clamping piece. In addition, by setting the sandwiching piece at a position closer to the distal end side of the stacked sandwiching pieces, it is possible to effectively prevent the deformation on the distal end side where the stacked sandwiching pieces are likely to be deformed.

(5)前記電線は、金属素線が撚り合わされた撚り線であり、前記第1圧接端子は、前記一対の第1挟持片を複数個平行に配置して構成されているとともに、前記第2圧接端子は、前記一対の第2挟持片を複数個平行に配置して構成されている。
このようにすれば、撚り線を複数箇所で圧接することになるため、撚り線がほどけるような圧接端子の回転を防止することをできる。また、圧接端子の個数が多くなることで電線との接触面積を多くなるとともに、組み合わされた状態の圧接端子の形状が安定しやすくなる。
(5) The electric wire is a stranded wire in which metal strands are twisted together, and the first pressure contact terminal is configured by arranging a plurality of the pair of first sandwiching pieces in parallel, and the second The press contact terminal is configured by arranging a plurality of the pair of second clamping pieces in parallel.
If it does in this way, since a strand wire will be press-contacted in multiple places, rotation of the press-contact terminal which can unwind a strand wire can be prevented. Further, as the number of the press contact terminals increases, the contact area with the electric wire increases, and the shape of the press contact terminal in the combined state is easily stabilized.

(6)前記第1圧接端子及び前記第2圧接端子のうちの一方には、電線端末が接続される接続部が設けられている。
(7)前記第1圧接端子及び前記第2圧接端子は、同一形状である。
このようにすれば、第1及び第2圧接端子を共通化できるため、第1及び第2圧接端子を形成するための金型を共通化することができる。
(6) One of the first press contact terminal and the second press contact terminal is provided with a connection portion to which an electric wire terminal is connected.
(7) The first press contact terminal and the second press contact terminal have the same shape.
In this way, since the first and second press contact terminals can be shared, the molds for forming the first and second press contact terminals can be shared.

本発明の圧接端子によれば、電線との接触不良を防止することが可能になる。   According to the press contact terminal of the present invention, it is possible to prevent poor contact with the electric wire.

本実施形態によれば、以下の効果を奏する。
(1)一対の第1挟持片14,14の間に電線W1が挿通されて圧接される第1圧接端子11と、一対の第2挟持片23,23の間に電線W1が挿通されて圧接される第2圧接端子20とを第1挟持片14,14と第2挟持片23,23とが重なるように組み合わせて構成される圧接端子10であって、第1圧接端子11には、一対の第2挟持片23,23間の間隔が広がる方向への第2挟持片23,23の変形を規制する第1変形規制部17,17が設けられるとともに、第2圧接端子20には、一対の第1挟持片14,14間の間隔が広がる方向への第1挟持片14,14の変形を規制する第2変形規制部26,26が設けられている。
According to this embodiment, the following effects can be obtained.
(1) The electric wire W1 is inserted between the pair of first sandwiching pieces 14 and 14, and the first press contact terminal 11 is press-contacted, and the electric wire W1 is inserted between the pair of second sandwiching pieces 23 and 23 and press-contacted. The second press contact terminal 20 is a press contact terminal 10 configured such that the first sandwiching pieces 14, 14 and the second sandwiching pieces 23, 23 overlap with each other. Are provided with first deformation restricting portions 17 and 17 for restricting the deformation of the second sandwiching pieces 23 and 23 in the direction in which the distance between the second sandwiching pieces 23 and 23 is widened. There are provided second deformation restricting portions 26 and 26 for restricting deformation of the first sandwiching pieces 14 and 14 in the direction in which the interval between the first sandwiching pieces 14 and 14 increases.

このようにすれば、第1圧接端子11の第1変形規制部17,17により一対の第2挟持片23,23間の間隔が広がる方向への第2挟持片23,23の変形が規制されるため、電線W1と第2挟持片23,23との間の接触圧が弱くなることによる接触不良を防止することができる。また、第2圧接端子20の第2変形規制部26,26により一対の第1挟持片14,14間の間隔が広がる方向への第1挟持片14,14の変形が規制されるため、電線W1と第1挟持片14,14との間の接触圧が弱くなることによる接触不良を防止することができる。よって、電線W1と圧接端子10との間の接触不良を防止することができる。
また、圧接端子10を1個で構成する場合と比較して、電線W1との接触面積を多くできるため、電気抵抗を少なくすることができる。
If it does in this way, the deformation | transformation of the 2nd clamping pieces 23 and 23 to the direction where the space | interval between a pair of 2nd clamping pieces 23 and 23 spreads by the 1st deformation | transformation control parts 17 and 17 of the 1st press-contact terminal 11 will be controlled. Therefore, it is possible to prevent contact failure due to weakening of the contact pressure between the electric wire W1 and the second holding pieces 23 and 23. In addition, since the deformation of the first sandwiching pieces 14 and 14 in the direction in which the distance between the pair of first sandwiching pieces 14 and 14 is increased is restricted by the second deformation restricting portions 26 and 26 of the second press contact terminal 20, the electric wires Contact failure due to weakening of the contact pressure between W1 and the first sandwiching pieces 14, 14 can be prevented. Therefore, poor contact between the electric wire W1 and the press contact terminal 10 can be prevented.
Moreover, since the contact area with the electric wire W1 can be increased as compared with the case where the pressure contact terminal 10 is configured by one, the electrical resistance can be reduced.

(2)第1変形規制部17及び第2変形規制部26は、各挟持片14,23の側縁部から挟持片14,23が重なる側に突出しているため、圧接端子10の構成を簡素化することができる。
(3)第1変形規制部17及び第2変形規制部26は、挟持片14,23の側縁部から挟持片の面に沿う方向に折り返す折り返し片であるため、第1及び第2圧接端子10,20のうちの一方の折り返し片の内側に第1及び第2圧接端子10,20のうちの他方の挟持片を保持することが可能になる。
(4)各挟持片14,23に設けられた折り返し片は、当該挟持片14(23)に重ねられた挟持片23(14)の面に当接しているため、第1及び第2圧接端子11,20間の接触面積を大きくすることができ、電気抵抗を少なくすることが可能になる。
(2) Since the first deformation restricting portion 17 and the second deformation restricting portion 26 protrude from the side edge portions of the sandwiching pieces 14 and 23 to the side where the sandwiching pieces 14 and 23 overlap, the configuration of the press contact terminal 10 is simplified. Can be
(3) Since the first deformation restricting portion 17 and the second deformation restricting portion 26 are folded pieces that are folded back in the direction along the surface of the sandwiching pieces from the side edges of the sandwiching pieces 14 and 23, the first and second press contact terminals. It becomes possible to hold the other clamping piece of the first and second press contact terminals 10 and 20 inside one folded piece of 10 and 20.
(4) Since the folded piece provided on each clamping piece 14, 23 is in contact with the surface of the clamping piece 23 (14) superimposed on the clamping piece 14 (23), the first and second press contact terminals The contact area between 11 and 20 can be increased, and the electrical resistance can be reduced.

(5)第1変形規制部17,17及び第2変形規制部26,26は、各挟持片の基端部であって、当該挟持片14(23)に重ねられた挟持片23(14)における先端側寄りの位置に形成されている。
このようにすれば、第1変形規制部17,17及び第2変形規制部26,26を挟持片14,23の基端部に形成することで比較的挟持片14,23の変形による影響を受けないようにすることができる。また、この挟持片14(23)を重ねられた挟持片23(14)における先端側寄りの位置とすることで、変形が生じやすい部分である重ねられた挟持片23(14)の先端側の変形を防止することができる。
(5) The first deformation restricting portions 17 and 17 and the second deformation restricting portions 26 and 26 are base end portions of the respective holding pieces, and the holding pieces 23 (14) stacked on the holding pieces 14 (23). Is formed at a position closer to the tip side.
If it does in this way, the 1st deformation | transformation control part 17 and 17 and the 2nd deformation control part 26 and 26 are formed in the base end part of the clamping pieces 14 and 23, and the influence by a deformation | transformation of the clamping pieces 14 and 23 is comparatively produced. It can be made not to receive. In addition, by setting the sandwiching piece 14 (23) closer to the distal end side of the stacked sandwiching piece 23 (14), the distal end side of the stacked sandwiching piece 23 (14), which is a portion that easily deforms, is arranged. Deformation can be prevented.

(6)電線W1は、金属素線が撚り合わされた撚り線であり、第1圧接端子11は、一対の第1挟持片14,14を複数個平行に配置して構成されているとともに、第2圧接端子20は、一対の第2挟持片23,23を複数個平行に配置して構成されている。
このようにすれば、撚り線を複数箇所で圧接することになるため、撚り線がほどけるように圧接端子10が回転することを防止することをできる。また、電線W1との接触面積を多くなるとともに、圧接端子10の形状が安定しやすくなる。
(6) The electric wire W1 is a stranded wire in which metal strands are twisted together, and the first press contact terminal 11 is configured by arranging a plurality of pairs of first sandwiching pieces 14 and 14 in parallel, and The two pressure contact terminals 20 are configured by arranging a plurality of pairs of second clamping pieces 23 and 23 in parallel.
If it does in this way, since a stranded wire will be press-contacted in multiple places, it can prevent that the press-contact terminal 10 rotates so that a stranded wire can be unwound. Further, the contact area with the electric wire W1 is increased, and the shape of the press contact terminal 10 is easily stabilized.

各第1挟持片44の先端部は、その両側がテーパ状に切欠かれている。
The two first pressure contact portions 43, 43 have the same shape and both include a pair of first sandwiching pieces 44, 44 extending downward, and between the pair of first sandwiching pieces 44, 44. Two (a plurality of) electric wires W3 and W4 are inserted between the formed U-shaped first slots 45 and are in pressure contact therewith.
Both ends of the tip of each first clamping piece 44 are notched in a tapered shape.

第1スロット45は、一対の第1挟持片44,44間に一定の間隔を空けるものであり、導体部の直径よりわずかに小さい。第1スロット45の上下方向(圧接方向)の長さは、2本の電線W1,W2を挿通できる長さであるため、実施形態1よりも長くなっている。第1スロット45の基端部は、導体部の形状に対応して半円弧状に縮径して形成されており、第1スロット45のテーパ状に切欠かれた先端側は、電線W1,W2を案内する案内部46とされている。

The first slot 45 is spaced apart from the pair of first sandwiching pieces 44, 44 and is slightly smaller than the diameter of the conductor portion. The length of the first slot 45 in the vertical direction (pressure contact direction) is longer than that of the first embodiment because it is a length through which the two electric wires W1 and W2 can be inserted. The proximal end portion of the first slot 45 is formed to have a reduced diameter in a semicircular arc shape corresponding to the shape of the conductor portion, and the distal end side of the first slot 45 cut out in a tapered shape is the electric wires W1, W2. It is set as the guide part 46 which guides.
