しかしながら、前記コネクタでは、端子の可動部が固定ハウジングの上下方向に屈曲しながら前後方向に延びるように形成されているため、可動部の前後方向の寸法が大きくなり、コネクタ全体が大型化するという問題点があった。また、可動部の寸法を小さくすると、可動部の変形量が十分に得られず、固定ハウジングに対する可動ハウジングの位置ずれ吸収効果が不十分になるとともに、可動部の応力が大きくなり、端子の耐久性を低下させるという問題点があった。 However, in the connector, since the movable part of the terminal is formed to extend in the front-rear direction while bending in the vertical direction of the fixed housing, the dimension of the movable part in the front-rear direction is increased, and the entire connector is increased in size. There was a problem. Also, if the size of the movable part is reduced, the amount of deformation of the movable part cannot be obtained sufficiently, the effect of absorbing the displacement of the movable housing relative to the fixed housing becomes insufficient, the stress of the movable part increases, and the durability of the terminal is increased. There was a problem of reducing the performance.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、端子の可動部の寸法を小さくすることができるとともに、可動部の変形量を十分に得ることのできるコネクタを提供することにある。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a connector capable of reducing the size of the movable part of the terminal and sufficiently obtaining the deformation amount of the movable part. It is to provide.

本発明は前記目的を達成するために、基板に固定され、接続対象物が上下方向に挿抜される固定ハウジングと、固定ハウジングに対して移動自在に設けられた可動ハウジングと、一端側を可動ハウジングに保持されるとともに、他端側を固定ハウジングに保持された複数の端子とを備え、固定ハウジングに対する可動ハウジングの移動を端子の弾性変形によって許容するようにしたコネクタにおいて、前記端子の一端側と他端側との間に板厚方向に弾性変形可能な複数の板状の可動部を設け、各可動部を互いに板厚方向が異なる方向となるように形成し、各可動部のうち、一部の可動部を板厚方向に弾性変形可能に形成し、他の可動部を一部の可動部と同一方向に弾性変形するように板厚方向に直交する方向に弾性変形可能に形成している。 In order to achieve the above object, the present invention provides a fixed housing that is fixed to a substrate and into which an object to be connected is inserted and removed in a vertical direction, a movable housing that is movably provided with respect to the fixed housing, and a movable housing on one end side. A connector having a plurality of terminals held at the other end and held by the fixed housing, and allowing the movement of the movable housing relative to the fixed housing by elastic deformation of the terminals; the movable portion in the thickness direction of the plurality of elastically deformable plate-like between the other end is provided, formed to the thickness direction of the movable portion to each other is different directions, of the movable part, one The movable part of the part is formed to be elastically deformable in the plate thickness direction, and the other movable part is formed to be elastically deformable in the direction perpendicular to the plate thickness direction so as to be elastically deformed in the same direction as some of the movable parts. Yes.

これにより、端子に互いに板厚方向が異なる方向となるように形成された複数の可動部がそれぞれ弾性変形することから、各可動部による変形量が十分に得られるとともに、各可動部全体の寸法が一方向に大きくなることもない。この場合、一部の可動部が板厚方向に弾性変形可能に形成され、他の可動部が一部の可動部と同一方向に弾性変形するように板厚方向に直交する方向に弾性変形可能に形成されていることから、一部の可動部の板厚方向への変形量が大きくなる。 As a result, since the plurality of movable parts formed so that the thickness directions of the terminals are different from each other are elastically deformed, the amount of deformation by each movable part can be sufficiently obtained, and the dimensions of each movable part as a whole are obtained. Does not grow in one direction. In this case, some of the movable parts can be elastically deformed in the plate thickness direction, and other movable parts can be elastically deformed in the direction perpendicular to the plate thickness direction so as to be elastically deformed in the same direction as some of the movable parts. Therefore, the amount of deformation of some of the movable parts in the plate thickness direction increases.

本発明によれば、各可動部全体の寸法が一方向に大きくなることがないので、コネクタ全体の小型化を図ることができる。この場合、各可動部による変形量を十分に得ることができるので、固定ハウジングに対する可動ハウジングの位置ずれ吸収効果を高めることができるとともに、可動部の応力を小さくすることができ、端子の耐久性を向上させることもできる。この場合、一部の可動部の板厚方向への変形量を大きくすることができるので、同方向への変形量を大きくしたい場合に極めて有利である。 According to the present invention, since the dimensions of the entire movable parts do not increase in one direction, the entire connector can be reduced in size. In this case, since the amount of deformation by each movable part can be sufficiently obtained, the effect of absorbing the displacement of the movable housing relative to the fixed housing can be enhanced, the stress of the movable part can be reduced, and the durability of the terminal Can also be improved. In this case, the amount of deformation of some of the movable parts in the plate thickness direction can be increased, which is extremely advantageous when it is desired to increase the amount of deformation in the same direction.

At that time, when the counterpart terminal 2 is inserted into the movable housing 20, the counterpart terminal 2 is sandwiched between the contact pieces 31a and 31b while spreading the contact pieces 31a and 31b of the contact portion 31 of the terminal 30, When the contact pieces 31 a and 31 b are in pressure contact with the mating terminal 2, the mating terminal 2 and the terminal 30 are connected.

前記接続状態において、例えば一方の基板１または他方の基板の撓みや振動により基板同士が互いに位置ずれを生ずると、各端子３０の可動部３３，３４，３５の弾性変形によって可動ハウジング２０の移動が許容され、基板同士の位置ずれが吸収される。即ち、基板同士が前後方向（Ｘ方向）に位置ずれを生ずると、第１の可動部３３が前後方向に弾性変形する。その際、接触部３１では、図２０に示すように、各接触片３１ａ，３１ｂによって挟持された相手側端子２が、二つの第１の接点部３１ａ−１と、各第１の接点部３１ａ−１の間に位置する一つの第２の接点部３１ｂ−１に三点で圧接していることから、各接点部３１ａ−１，３１ｂ−１を中心とする相手側端子２の回動（図２０中実線矢印方向の回動）が抑制される。また、基板同士が幅方向（Ｙ方向）に位置ずれを生ずると、第１の可動部３３が幅方向に弾性変形し、基板同士が上下方向（Ｚ方向）に位置ずれを生ずると、第２の可動部３４及び第３の可動部３５がそれぞれ上下方向に弾性変形する。 In the connected state, when the substrates are displaced from each other due to, for example, bending or vibration of one substrate 1 or the other substrate, the movable housing 20 is moved by elastic deformation of the movable portions 33, 34, and 35 of each terminal 30. It is allowed and the positional deviation between the substrates is absorbed. That is, when the substrates are displaced in the front-rear direction (X direction), the first movable portion 33 is elastically deformed in the front-rear direction. In that case, in the contact part 31, as shown in FIG. 20, the other party terminal 2 pinched | interposed by each contact piece 31a, 31b is the two 1st contact parts 31a-1 and each 1st contact part 31a. -1 is in contact with one second contact portion 31b-1 located between the three contact points 31a-1 and 31b-1 , so that the counterpart terminal 2 is rotated ( The rotation in the direction of the solid arrow in FIG. 20 is suppressed. When the substrates are displaced in the width direction (Y direction), the first movable portion 33 is elastically deformed in the width direction, and when the substrates are displaced in the vertical direction (Z direction), the second is generated. The movable portion 34 and the third movable portion 35 are elastically deformed in the vertical direction.

このように、本実施形態によれば、端子３０の一端側と他端側との間に弾性変形可能な複数の板状の第１、第２及び第３の可動部３３，３４，３５を設け、第１の可動部３３を第２及び第３の可動部３４，３５と板厚方向が異なる方向となるように形成したので、各可動部３３，３４，３５全体の寸法が一方向に大きくなることがなく、コネクタ全体の小型化を図ることができる。この場合、各可動部３３，３４，３５による変形量を十分に得ることができるので、固定ハウジング１０に対する可動ハウジング２０の位置ずれ吸収効果を高めることができるとともに、可動部３３，３４，３５の応力を小さくすることができ、端子３０の耐久性を向上させることもできる。 As described above, according to the present embodiment, the plurality of plate-like first, second, and third movable portions 33, 34, and 35 that are elastically deformable between the one end side and the other end side of the terminal 30 are provided. Since the first movable part 33 is formed so that the plate thickness direction is different from that of the second and third movable parts 34, 35, the overall dimensions of the movable parts 33, 34, 35 are in one direction. The entire connector can be reduced in size without becoming large. In this case, a sufficient amount of deformation can be obtained by the movable parts 33, 34, and 35, so that the effect of absorbing the displacement of the movable housing 20 with respect to the fixed housing 10 can be enhanced, and the movable parts 33, 34, and 35 are The stress can be reduced, and the durability of the terminal 30 can be improved.

更に、前記各可動部３３，３４，３５のうち、第２及び第３の可動部３４，３５を板厚方向（上下方向）に弾性変形可能に形成し、第１の可動部３３を第２及び第３の可動部３４，３５と同一方向に弾性変形するように板厚方向（前後方向）に直交する方向（上下方向）に弾性変形可能に形成したので、上下方向への変形量を大きくしたい場合に極めて有利である。 Further, among the movable parts 33, 34, 35, the second and third movable parts 34, 35 are formed so as to be elastically deformable in the plate thickness direction (vertical direction), and the first movable part 33 is the second movable part 33. And, since it is formed to be elastically deformable in the direction (vertical direction) perpendicular to the plate thickness direction (front-rear direction) so as to be elastically deformed in the same direction as the third movable parts 34, 35, the amount of deformation in the vertical direction is increased. It is extremely advantageous if you want to do so.

また、端子３０の第１の可動部３３を固定ハウジング１０の前後方向に直交する方向（上下方向及び幅方向）に延びるように形成し、第１の可動部３３の前後方向の弾性変形によって可動ハウジング２０の前後方向の移動を許容するようにしたので、第１の可動部３３を前後方向に長く形成することなく第１の可動部３３の前後方向への変形量を十分に得ることができる。これにより、第１の可動部３３の前後方向の寸法を小さくすることができ、コネクタ全体２の前後方向の小型化を図ることができる。 Further, the first movable portion 33 of the terminal 30 is formed so as to extend in a direction (vertical direction and width direction) orthogonal to the front-rear direction of the fixed housing 10, and is movable by elastic deformation of the first movable portion 33 in the front-rear direction. Since the housing 20 is allowed to move in the front-rear direction, the first movable part 33 can be sufficiently deformed in the front-rear direction without forming the first movable part 33 long in the front-rear direction. . Thereby, the dimension of the front-back direction of the 1st movable part 33 can be made small, and size reduction of the front-back direction of the whole connector 2 can be achieved.

この場合、第１の可動部３３を板厚方向が前後方向となる板状に形成したので、第１の可動部３３を前後方向に容易に弾性変形させることができるとともに、第１の可動部３３の前後方向の寸法をより一層小さくすることができる。 In this case, since the first movable portion 33 is formed in a plate shape whose plate thickness direction is the front-rear direction, the first movable portion 33 can be easily elastically deformed in the front-rear direction, and the first movable portion The size in the front-rear direction of 33 can be further reduced.

また、第１の可動部３３に、上下方向の一部を他の部分よりも幅方向一方に突出させた第１の突出部３３ｈと、上下方向の一部を他の部分よりも幅方向他方に突出させた第２の突出部３３ｉとを設け、互いに幅方向に隣り合う端子３０の第１の可動部３３同士を、第１の突出部３３ｈと第２の突出部３３ｉとが互いに上下に位置するように配置したので、各端子３０を各突出部３３ｈ，３３ｉ同士が上下に位置するように互いに幅方向に近接させて配置することができる。これにより、各端子３０の第１の可動部３３の配置スペースを固定ハウジング１０の幅方向に拡大させることなく第１の可動部３３の幅方向の長さを大きくすることができ、第１の可動部３３の変形量を大きくする場合に極めて有利である。 Also, the first movable portion 33 has a first protruding portion 33h in which a part in the vertical direction protrudes in one width direction from the other part, and a part in the vertical direction in the other width direction than the other part. And the first movable portions 33 of the terminals 30 adjacent to each other in the width direction, and the first protruding portion 33h and the second protruding portion 33i are vertically Since it arrange | positions so that it may be located, each terminal 30 can be mutually arrange | positioned in the width direction so that each protrusion part 33h, 33i may be located up and down. Thereby, the length in the width direction of the first movable portion 33 can be increased without increasing the arrangement space of the first movable portion 33 of each terminal 30 in the width direction of the fixed housing 10. This is extremely advantageous when the deformation amount of the movable portion 33 is increased.

更に、基板接続部３２の接続部３２ｂに、前後方向に延びる切り欠き部３２ｅを設けたので、半田が接続部３２ｂの外周縁のみならず切り欠き部３２ｅ内の縁部にも回り込み、基板接続部３２と基板１との半田付け部分を十分に確保することができる。これにより、半田付け部分の接合強度を高めることができるので、切り欠き部３２ｅを有する分だけ基板接続部３２の接続部３２ｂを前後方向に小さく形成することができ、コネクタ全体の前後方向の小型化に極めて有利である。 Further, since the notch 32e extending in the front-rear direction is provided in the connecting part 32b of the board connecting part 32, the solder wraps around not only the outer peripheral edge of the connecting part 32b but also the edge in the notch 32e. A sufficient soldering portion between the portion 32 and the substrate 1 can be secured. Thereby, since the joining strength of the soldered portion can be increased, the connecting portion 32b of the board connecting portion 32 can be formed smaller in the front-rear direction by the amount of the notch 32e, and the entire connector can be reduced in the front-rear direction. It is extremely advantageous for the conversion.

また、端子３０の第１及び第２の接触片３１ａ，３１ｂによって挟持された相手側端子２を、二つの第１の接点部３１ａ−１と、各第１の接点部３１ａ−１の間に位置する一つの第２の接点部３１ｂ−１に三点で圧接させるようにしたので、各接点部３１ａ−１，３１ｂ−１を中心とする相手側端子２の回動を抑制することができ、相手側端子２の回動による各接触片３１ａ，３１ｂとの摺動を防止することができる。これにより、端子３０の接触部３０または相手側端子２の表面にメッキ等の導電被膜が設けられている場合の導電被膜の剥離、接触信頼性の低下、抵抗の増加など、接触部分における摺動による不具合の発生を効果的に防止することができる。 Further, the counterpart terminal 2 sandwiched between the first and second contact pieces 31a and 31b of the terminal 30 is placed between the two first contact portions 31a-1 and the first contact portions 31a-1. Since one second contact portion 31b-1 is press-contacted at three points, rotation of the counterpart terminal 2 around each contact portion 31a-1, 31b-1 can be suppressed. The sliding with the contact pieces 31a and 31b due to the rotation of the counterpart terminal 2 can be prevented. As a result, when the conductive film such as plating is provided on the contact portion 30 of the terminal 30 or the surface of the mating terminal 2, the conductive film is peeled off, the contact reliability is lowered, the resistance is increased, and the sliding at the contact portion is performed. It is possible to effectively prevent the occurrence of problems due to the above.

尚、前記実施形態では、第２の接触片３１ｂに一つの第２の接点部３１ｂ−１を設けたものを示したが、二つ以上設けるようにしてもよい。 In the above embodiment, the second contact piece 31b is provided with one second contact portion 31b-1, but two or more may be provided.

また、前記実施形態では、第１の可動部３３を第２及び第３の可動部３４，３５と板厚方向が直交するように形成したものを示したが、各可動部を９０゜以外の角度をなすように形成することにより、互いに板厚方向が異なる方向となるように形成してもよい。 In the above-described embodiment, the first movable portion 33 is formed so that the plate thickness direction is orthogonal to the second and third movable portions 34 and 35. You may form so that a plate | board thickness direction may become a mutually different direction by forming so that an angle may be made.
