Description

本発明は、電気接続に使用されるコネクタに関する。   The present invention relates to a connector used for electrical connection.

電気接続に使用されるコネクタの一例として、車両に搭載されるコネクタが特許文献1に記載されている。この特許文献1に記載されたコネクタ100は、図12に示すように、略円筒形状の雌端子110と、略円筒形状の雄端子120と、略円筒形状の弾性部材130とで構成される。弾性部材130は、環状の枠部を接続する複数本のバネ部133が、弾性力を持ちかつ隙間をあけて平行に配設されている形状である。   As an example of a connector used for electrical connection, a connector mounted on a vehicle is described in Patent Document 1. As shown in FIG. 12, the connector 100 described in Patent Document 1 includes a substantially cylindrical female terminal 110, a substantially cylindrical male terminal 120, and a substantially cylindrical elastic member 130. The elastic member 130 has a shape in which a plurality of spring portions 133 that connect the annular frame portions have an elastic force and are arranged in parallel with a gap therebetween.

雌端子110の内側には、雌端子110と電気的接触を持つ状態で弾性部材130が組み込まれている。雌端子110に雄端子120が挿入されると、雄端子120の外周面に弾性部材130の複数本のバネ部133が接触する。この複数の接触点によって、雌端子110と雄端子120とが電気的に接続される。弾性部材130の接触荷重(バネ荷重)によって雄端子120に与えられる摩擦力は、コネクタ100の振動に起因した雌端子に対する雄端子の相対的な動きを抑制する。   An elastic member 130 is incorporated inside the female terminal 110 so as to be in electrical contact with the female terminal 110. When the male terminal 120 is inserted into the female terminal 110, the plurality of spring portions 133 of the elastic member 130 come into contact with the outer peripheral surface of the male terminal 120. The female terminal 110 and the male terminal 120 are electrically connected by the plurality of contact points. The frictional force applied to the male terminal 120 by the contact load (spring load) of the elastic member 130 suppresses the relative movement of the male terminal with respect to the female terminal due to the vibration of the connector 100.

特開2013−187170号公報JP 2013-187170 A

上記特許文献1に記載されたコネクタの構造では、コネクタへ印加される振動によって生じる雌端子に対する雄端子の相対的な動きの抑制は、バネ部の接触荷重による押圧力に依存する。このため、コネクタへ印加される振動の大きさが押圧力を越えてしまうと、コネクタにおける雌端子に対する雄端子の相対的な動きを抑制できなくなるおそれがある。雌端子に対する雄端子の相対的な動きは、端子間の接点摺動を引き起こし、ひいては接点磨耗による抵抗値の増大を生じさせる。   In the structure of the connector described in Patent Document 1, suppression of relative movement of the male terminal with respect to the female terminal caused by vibration applied to the connector depends on the pressing force due to the contact load of the spring portion. For this reason, if the magnitude of vibration applied to the connector exceeds the pressing force, the relative movement of the male terminal with respect to the female terminal in the connector may not be suppressed. The relative movement of the male terminal with respect to the female terminal causes contact sliding between the terminals, which in turn causes an increase in resistance due to contact wear.

本発明は、上記課題を鑑みて、コネクタへ印加される振動によって生じる雌端子に対する雄端子の相対的な動きを抑制できる構造を有した、コネクタを提供することを目的とする。   In view of the above problems, an object of the present invention is to provide a connector having a structure capable of suppressing the relative movement of a male terminal with respect to a female terminal caused by vibration applied to the connector.

上記課題を解決するために、本第1の発明のコネクタは、円柱形状の雄端子と、雄端子を挿入する筒部を有した円筒形状の雌端子と、雌端子の筒部の内部に組み込まれる弾性部材とを備え、雌端子の筒部の内壁には、内側に突出した複数の突起部が形成されており、複数の突起部は、少なくとも、筒部の軸心と垂直かつ第1のなす角で軸心上の一点から伸びる二本の直線が筒部の内壁と交わる位置に設けた2つの第1の突起部と、筒部の軸心と垂直かつ第2のなす角で軸心上の一点から伸びる二本の直線が筒部の内壁と交わる位置に設けた2つの第2の突起部とを、軸心と平行な方向に設けて構成され、弾性部材が、筒部に挿入された雄端子を複数の突起部側に付勢する、ことを特徴としている。 In order to solve the above problems, the connector of the present first invention comprises a male terminal cylindrical, and the female terminal of the cylindrical shape having a cylindrical portion for inserting a male terminal, incorporated in the cylindrical portion of the female terminal A plurality of protrusions projecting inwardly are formed on the inner wall of the cylindrical portion of the female terminal, and the plurality of protrusions are at least perpendicular to the axis of the cylindrical portion and the first Two first protrusions provided at positions where two straight lines extending from one point on the axis at the angle formed intersect with the inner wall of the cylinder part, and an axis centered at a second angle formed perpendicular to the axis of the cylinder part Two second protrusions provided at positions where two straight lines extending from one point above the inner wall of the cylinder part are provided in a direction parallel to the axis, and an elastic member is inserted into the cylinder part The male terminal thus formed is biased toward the plurality of protrusions.

この本第1の発明のコネクタによれば、雄端子を挿入して嵌合する雌端子の筒部の内部に、筒部に挿入された雄端子を保持する弾性部材が組み込まれている。また、雌端子の筒部の内壁には、内側に突出した突起部を形成している。これにより、雌端子の筒部に挿入された雄端子を、雌端子の筒部の内壁に形成された突起部と、弾性力を有した弾性部材とで、狭持することができる。弾性部材は、筒部に挿入された雄端子を複数の突起部側に付勢する。この突起部は、弾性力を有さないので雄端子の動きが規制される。従って、コネクタへ印加される振動によって生じる雌端子に対する雄端子の相対的な動きを抑制できる。例えば、コネクタへ印加される振動の大きさが雄端子を保持する押圧力を越えても、突起部によって雄端子の動きが規制されるので、雄端子と雌端子(バネ部材)との間の接点摺動が生じて接点磨耗による抵抗値が増大するおそれを低減させることができる。   According to the connector of the first aspect of the present invention, the elastic member that holds the male terminal inserted into the cylindrical portion is incorporated into the cylindrical portion of the female terminal into which the male terminal is inserted and fitted. In addition, a protrusion projecting inward is formed on the inner wall of the cylindrical portion of the female terminal. Thereby, the male terminal inserted into the cylindrical portion of the female terminal can be held between the protrusion formed on the inner wall of the cylindrical portion of the female terminal and the elastic member having elastic force. The elastic member biases the male terminal inserted into the cylindrical portion toward the plurality of protruding portions. Since this protrusion has no elastic force, the movement of the male terminal is restricted. Therefore, the relative movement of the male terminal with respect to the female terminal caused by the vibration applied to the connector can be suppressed. For example, even if the magnitude of the vibration applied to the connector exceeds the pressing force for holding the male terminal, the movement of the male terminal is restricted by the protrusion, so the gap between the male terminal and the female terminal (spring member) It is possible to reduce the possibility of contact sliding and increasing the resistance value due to contact wear.

また、本第2の発明のコネクタは、第1の発明において、2つの第1の突起部の第1のなす角と、2つの第2の突起部の第2のなす角とが、同じ角度であることを特徴とする。   In the connector according to the second invention, in the first invention, the angle formed by the first of the two first protrusions and the angle formed by the second of the two second protrusions are the same angle. It is characterized by being.

さらに、本第3の発明のコネクタは、2つの第1の突起部と、2つの第2の突起部とが、筒部の軸心と平行な同一平面上に設けられることを特徴とする。   Furthermore, the connector according to the third aspect of the invention is characterized in that the two first protrusions and the two second protrusions are provided on the same plane parallel to the axis of the cylindrical portion.

この第2および本第3の発明のコネクタによれば、このように設けられた2つの第1の突起部および2つの第2の突起部と弾性部材とによって雄端子を保持することにより、上下左右方向の振動および上下こじり方向の振動を、効果的に抑制することができる。   According to the connector of the second and third inventions, the male terminal is held by the two first protrusions and the two second protrusions and the elastic member provided in this way, so that The vibration in the horizontal direction and the vibration in the vertical direction can be effectively suppressed.

以上述べたように、本発明のコネクタによれば、コネクタへ印加される振動によって生じる雌端子に対する雄端子の相対的な動きを抑制できる。   As described above, according to the connector of the present invention, the relative movement of the male terminal with respect to the female terminal caused by the vibration applied to the connector can be suppressed.

以下、本発明に係るコネクタの一実施形態について、図面を参照しながら説明する。   Hereinafter, an embodiment of a connector according to the present invention will be described with reference to the drawings.

[概要]
本発明に係るコネクタは、丸ピン型の雄端子と嵌合する円筒型の雌端子の円筒部の内壁に、内側に突出した突起部を形成している。また、一部に弾性力を持つバネ部を有した弾性部材を、雌端子の円筒部内に組み込んでいる。この際、弾性部材を、バネ部が突起部と対向する位置となるように組み込む。この突起部と弾性部材のバネ部とによって、雌端子の円筒部に嵌合された雄端子を押圧して保持する。これにより、コネクタへ印加される振動の大きさが雄端子を保持する押圧力を越えても、突起部によって動きが規制される。従って、雌端子に対する雄端子の相対的な動きを抑制できる。
[Overview]
The connector which concerns on this invention forms the protrusion part which protruded inward on the inner wall of the cylindrical part of the cylindrical female terminal fitted to a round pin type male terminal. In addition, an elastic member having a spring part having an elastic force in part is incorporated in the cylindrical part of the female terminal. At this time, the elastic member is incorporated so that the spring portion is positioned opposite the protrusion. The male terminal fitted to the cylindrical portion of the female terminal is pressed and held by the protrusion and the spring portion of the elastic member. Thereby, even if the magnitude of the vibration applied to the connector exceeds the pressing force for holding the male terminal, the movement is restricted by the protrusion. Therefore, the relative movement of the male terminal with respect to the female terminal can be suppressed.

FIG. 1A is a perspective view for explaining the shape of each component constituting the connector 1. FIG.1 (b) is a perspective view which shows the state of the connector 1 with which the terminal was fitted. In FIG. 1A, in order to make the part shape easy to understand, a part of the configuration is transmitted and the inside is drawn. FIG. 2A is a cross-sectional view taken along line AA in FIG. FIG. 2B is a cross-sectional view taken along line B-B in FIG. FIG.2 (c) is CC sectional view taken on the line in Fig.2 (a). FIG.2 (d) is the DD sectional view taken on the line in FIG.2 (b).

図1に示すように、本実施形態に係るコネクタ1は、雌端子10と、雄端子20と、弾性部材30とを備えている。雌端子10の内部には、弾性部材30が組み込まれる。雄端子20は、弾性部材30が組み込まれた雌端子10の中に挿入される。本実施形態に係るコネクタ1は、雄端子20が雌端子10内に挿入されて嵌合されることにより(図1(b))、弾性部材30を介して雄端子20と雌端子10とが電気的に接続される。   As shown in FIG. 1, the connector 1 according to this embodiment includes a female terminal 10, a male terminal 20, and an elastic member 30. An elastic member 30 is incorporated in the female terminal 10. The male terminal 20 is inserted into the female terminal 10 in which the elastic member 30 is incorporated. In the connector 1 according to the present embodiment, the male terminal 20 and the female terminal 10 are connected via the elastic member 30 when the male terminal 20 is inserted into and fitted into the female terminal 10 (FIG. 1B). Electrically connected.

雄端子20は、導電性を有した金属材料で形成される略円柱形状の部材であり、いわゆる丸ピン型の端子である。雄端子20は、円柱状の挿入部21と、挿入部21に連設される導体バレル部22とで構成される。挿入部21の外周径は、後述する弾性部材30の枠部の内径および雌端子10の円筒部の内径よりも小さい(図2(b))。挿入部21の先端は、テーパー状になっており、雄端子20を雌端子10(弾性部材30)へ挿入し易くしている。導体バレル部22は、図示しない被覆電線の露出した導体部分と、カシメによる圧着や半田付けによって電気的に接続される箇所である。   The male terminal 20 is a substantially cylindrical member formed of a conductive metal material, and is a so-called round pin type terminal. The male terminal 20 includes a columnar insertion portion 21 and a conductor barrel portion 22 provided continuously to the insertion portion 21. The outer peripheral diameter of the insertion portion 21 is smaller than the inner diameter of the frame portion of the elastic member 30 and the inner diameter of the cylindrical portion of the female terminal 10 (FIG. 2B). The distal end of the insertion portion 21 is tapered to facilitate insertion of the male terminal 20 into the female terminal 10 (elastic member 30). The conductor barrel portion 22 is a portion that is electrically connected to an exposed conductor portion of a covered electric wire (not shown) by crimping or soldering with caulking.

弾性部材30は、導電性および弾力性を有した金属材料で形成される部材である。この弾性部材30は、環状の枠部31および32と、バネ部33とで構成される。枠部31および32の内周径は、雄端子20の挿入部21の外周径よりも大きい(図2(a))。バネ部33は、枠部31と枠部32とを、両枠部の軸心を略一致させて接続する。図1(a)の例では、3本のバネ部33で枠部31と枠部32とが接続されている。このバネ部33は、枠部31および32の軸心側に、中央部が湾曲した形状で成形されている(図1(a)、図2(a))。弾性部材30は、湾曲した中央部によって、嵌合する雄端子20を押圧して保持する(図2(b)、(d))。   The elastic member 30 is a member formed of a metal material having conductivity and elasticity. The elastic member 30 includes annular frame portions 31 and 32 and a spring portion 33. The inner peripheral diameters of the frame parts 31 and 32 are larger than the outer peripheral diameter of the insertion part 21 of the male terminal 20 (FIG. 2A). The spring part 33 connects the frame part 31 and the frame part 32 so that the axial centers of both frame parts substantially coincide. In the example of FIG. 1A, the frame portion 31 and the frame portion 32 are connected by three spring portions 33. The spring portion 33 is formed on the axial center side of the frame portions 31 and 32 so as to have a curved central portion (FIGS. 1A and 2A). The elastic member 30 presses and holds the mating male terminal 20 by the curved center portion (FIGS. 2B and 2D).

雌端子10は、導電性を有した金属材料で形成される略円筒形状の部材である。雌端子10は、円筒状の円筒部11と、円筒部11に連設される導体バレル部12とで構成される。導体バレル部12は、上述した導体バレル部22と同じく、図示しない被覆電線の露出した導体部分と、カシメによる圧着や半田付けによって電気的に接続される箇所である。   The female terminal 10 is a substantially cylindrical member formed of a conductive metal material. The female terminal 10 includes a cylindrical cylindrical portion 11 and a conductor barrel portion 12 provided continuously to the cylindrical portion 11. The conductor barrel portion 12 is a portion that is electrically connected to the exposed conductor portion of a covered electric wire (not shown) by crimping or soldering by caulking, like the conductor barrel portion 22 described above.

円筒部11は、雄端子20の挿入部21が挿入される箇所である。この円筒部11の内壁には、内側に突出した突起部が設けられている(図2(c))。この突起部は、例えば円筒部11の打ち出し加工などによって形成される。本実施形態の突起部は、円筒部11の雄端子20が挿入される側(以下、前側という)に形成された2つの前側突起部11a、および円筒部11の導体バレル部12が連設される側(以下、後側という)に形成された2つの後側突起部11bから構成される(図1(a))。2つの前側突起部(第1の突起部)11aは、円筒部11の軸心と垂直かつ所定のなす角(第1のなす角)で軸心上の一点から伸びる二本の直線が筒部の内壁と交わる位置に設けられる。2つの後側突起部(第2の突起部)11bは、円筒部11の軸心と垂直かつ所定のなす角(第2のなす角)で軸心上の一点から伸びる二本の直線が筒部の内壁と交わる位置に設けられる。すなわち、4つの前側突起部11aおよび後側突起部11bは、円筒部11の軸心と平行な同一平面上に設けられる。また、2つの前側突起部11aと2つの後側突起部11bとの間隔は、弾性部材30の長手方向の寸法(枠部31から枠部32までの長さ)よりも長い。   The cylindrical part 11 is a place where the insertion part 21 of the male terminal 20 is inserted. On the inner wall of the cylindrical portion 11, a protruding portion protruding inward is provided (FIG. 2C). This protrusion is formed, for example, by punching the cylindrical portion 11 or the like. In the protrusion of the present embodiment, two front protrusions 11a formed on the side of the cylindrical part 11 where the male terminal 20 is inserted (hereinafter referred to as the front side) and the conductor barrel part 12 of the cylindrical part 11 are connected. 1 is formed of two rear projections 11b formed on the rear side (hereinafter referred to as the rear side) (FIG. 1A). The two front protrusions (first protrusions) 11a are formed by two straight lines extending from one point on the axis at a predetermined angle (first angle) perpendicular to the axis of the cylinder 11 It is provided at a position that intersects the inner wall of the. The two rear protrusions (second protrusions) 11b are formed by two straight lines extending from one point on the axis perpendicular to the axis of the cylindrical part 11 and at a predetermined angle (second angle). It is provided at a position that intersects the inner wall of the section. That is, the four front protrusions 11 a and the rear protrusion 11 b are provided on the same plane parallel to the axis of the cylindrical part 11. Further, the distance between the two front protrusions 11a and the two rear protrusions 11b is longer than the length of the elastic member 30 in the longitudinal direction (the length from the frame part 31 to the frame part 32).

つまり、弾性部材30は、円筒部11の内部において、2つの前側突起部11aと2つの後側突起部11bとで挟まれる位置に、組み込まれる(図2(a))。この弾性部材30は、円筒部11の軸心を挟んで前側突起部11aおよび後側突起部11bと反対側にバネ部33が位置するように、円筒部11の内部に組み込まれる(図2(c))。従って、弾性部材30が、雌端子10の円筒部11に挿入された雄端子20を、前側突起部11aおよび後側突起部11bの方へ付勢することになる。   That is, the elastic member 30 is incorporated in the cylindrical portion 11 at a position sandwiched between the two front protrusions 11a and the two rear protrusions 11b (FIG. 2A). The elastic member 30 is incorporated into the cylindrical portion 11 so that the spring portion 33 is positioned on the opposite side of the front protruding portion 11a and the rear protruding portion 11b across the axis of the cylindrical portion 11 (FIG. 2 ( c)). Accordingly, the elastic member 30 biases the male terminal 20 inserted into the cylindrical portion 11 of the female terminal 10 toward the front protrusion 11a and the rear protrusion 11b.

図3を用いて、4つの前側突起部11aおよび後側突起部11bを設けることができる他の位置について説明する。図3(a)は、本コネクタ1に用いることができる他の雌端子10の断面図である。図3(b)は、図3(a)におけるC1−C1線断面図およびC2−C2線断面図の一例である。図3(c)は、図3(a)におけるC1−C1線断面図およびC2−C2線断面図の他の一例である。   With reference to FIG. 3, another position where the four front protrusions 11a and the rear protrusion 11b can be provided will be described. FIG. 3A is a cross-sectional view of another female terminal 10 that can be used for the connector 1. FIG. 3B is an example of a cross-sectional view taken along line C1-C1 and a cross-sectional view taken along line C2-C2 in FIG. FIG. 3C is another example of a cross-sectional view taken along line C1-C1 and a cross-sectional view taken along line C2-C2 in FIG.

図3(b)で示すように、2つの前側突起部11aのなす角θ1は、2つの後側突起部11bのなす角θ2と異なっていてもよい(θ1≠θ2)。また、図3(c)で示すように、2つの前側突起部11aの組が円筒部11の軸心に対して傾く角度θ3は、2つの後側突起部11bの組が円筒部11の軸心に対して傾く角度θ4と異なっていてもよい(θ3<θ4)。換言すれば、2つの前側突起部11aおよび2つの後側突起部11bは、円筒部11の軸心と平行な同一平面上に設けられていなくてもよい。   As shown in FIG. 3B, the angle θ1 formed by the two front projections 11a may be different from the angle θ2 formed by the two rear projections 11b (θ1 ≠ θ2). Further, as shown in FIG. 3C, the angle θ3 at which the set of the two front protrusions 11a is inclined with respect to the axial center of the cylindrical part 11 indicates that the set of the two rear protrusions 11b is the axis of the cylindrical part 11. It may be different from the angle θ4 inclined with respect to the heart (θ3 <θ4). In other words, the two front protrusions 11 a and the two rear protrusions 11 b may not be provided on the same plane parallel to the axis of the cylindrical part 11.

円筒部11の内壁に内側に突出した4つの前側突起部11aおよび後側突起部11bが少なくとも設けられていれば、この4つの突起部は整列して配置されていなくても、弾性部材30が、雌端子10の円筒部11に挿入された雄端子20を、4つの前側突起部11aおよび後側突起部11bの方へ付勢することが可能である。   If at least four front protrusions 11a and rear protrusions 11b projecting inwardly are provided on the inner wall of the cylindrical part 11, the elastic member 30 can be used even if the four protrusions are not aligned. The male terminal 20 inserted into the cylindrical portion 11 of the female terminal 10 can be urged toward the four front protrusions 11a and the rear protrusion 11b.

次に、図4乃至図6を参照して、内部に弾性部材30が組み込まれた雌端子10と雄端子20とが嵌合接続された状態のコネクタが、コネクタへ印加される振動に対してどのように作用するかについて説明する。この説明では、従来のコネクタ100との違いを比較しつつ本発明のコネクタの作用を説明する。
[Action of connector]

(1)挿抜方向の振動に対する作用
挿抜方向の振動とは、雄端子20を雌端子10へ挿入する方向および雄端子20を雌端子10から抜き出す方向に生じる振動である。この挿抜方向の振動では、雄端子20の軸心は、平行方向にもねじれ方向にも移動しない。
(1) Action on vibration in insertion / removal direction Vibration in the insertion / removal direction is vibration generated in a direction in which the male terminal 20 is inserted into the female terminal 10 and a direction in which the male terminal 20 is extracted from the female terminal 10. With this vibration in the insertion / extraction direction, the axis of the male terminal 20 does not move in either the parallel direction or the twist direction.

従来のコネクタ100は、図4(b)に示すように、弾性部材130を構成する複数本のバネ部133の接触荷重(バネ荷重)による摩擦力(白抜き矢印)で、雄端子120の外周面を全方向から保持する構造である。この構造のため、従来のコネクタ100では、挿抜方向の振動(実線矢印)による力が、複数本のバネ部133の接触荷重による摩擦力を越えてしまうと、雄端子120が挿抜方向に動いて雌端子110との間に相対的な動きが生じる。   As shown in FIG. 4B, the conventional connector 100 has a frictional force (white arrow) due to a contact load (spring load) of a plurality of spring parts 133 constituting the elastic member 130, and the outer periphery of the male terminal 120. This structure holds the surface from all directions. Due to this structure, in the conventional connector 100, when the force due to the vibration in the insertion / removal direction (solid arrow) exceeds the frictional force due to the contact load of the plurality of spring portions 133, the male terminal 120 moves in the insertion / removal direction. A relative movement occurs with the female terminal 110.

これに対し、本実施形態のコネクタ1は、図4(a)に示すように、弾性部材30を構成する3本のバネ部33の接触荷重(バネ荷重)による摩擦力(白抜き矢印)で、雄端子20の外周面の第1領域(図面では下側領域)を保持する構造である。加えて、本実施形態のコネクタ1は、雌端子10に設けられた4つの前側突起部11aおよび後側突起部11bによる摩擦力で、雄端子20の外周面の第2領域(図面では上側領域)を保持する構造である。この構造では、弾性部材30が有するバネ部33の接触荷重による保持力が従来に比べて少なくなるが、4つの前側突起部11aおよび後側突起部11bによる摩擦力で雄端子20の外周面の第2領域を保持する。つまり、弾性部材30が、雌端子10の円筒部11に挿入された雄端子20を、前側突起部11aおよび後側突起部11bの側へ付勢する。よって、挿抜方向の振動に対して、本実施形態のコネクタ1は、従来とほぼ同等の効果を発揮する。   On the other hand, as shown in FIG. 4A, the connector 1 of the present embodiment is a friction force (white arrow) due to the contact load (spring load) of the three spring portions 33 constituting the elastic member 30. The first terminal area (the lower area in the drawing) of the outer peripheral surface of the male terminal 20 is held. In addition, the connector 1 according to the present embodiment has a second region (an upper region in the drawing) of the outer peripheral surface of the male terminal 20 by frictional force generated by the four front protrusions 11a and the rear protrusions 11b provided on the female terminal 10. ). In this structure, the holding force due to the contact load of the spring portion 33 of the elastic member 30 is reduced as compared with the conventional case, but the frictional force of the four front protrusions 11a and the rear protrusion 11b causes the outer peripheral surface of the male terminal 20 to Hold the second region. That is, the elastic member 30 biases the male terminal 20 inserted into the cylindrical portion 11 of the female terminal 10 toward the front protrusion 11a and the rear protrusion 11b. Therefore, the connector 1 of the present embodiment exhibits substantially the same effect as the conventional one against vibration in the insertion / extraction direction.

(2)上下左右方向の振動に対する作用
上下左右方向の振動とは、上述した挿抜方向と直交する方向に生じる振動である。よって、振動方向は上下左右の4方向だけではなく、挿抜方向(円筒部11の軸心)を中心として360°の方向に生じる振動である。この上下左右方向の振動では、雄端子20の軸心は、平行方向に移動する。
(2) Action on vertical / horizontal vibration The vertical / horizontal vibration is a vibration generated in a direction perpendicular to the above-described insertion / extraction direction. Therefore, the vibration direction is vibration generated in a 360 ° direction centering on the insertion / extraction direction (axial center of the cylindrical portion 11) as well as the four directions of up, down, left and right. In this vertical and horizontal vibration, the axis of the male terminal 20 moves in the parallel direction.

従来のコネクタ100は、図5(b)に示すように、弾性部材130を構成する複数本のバネ部133(図面では8本)の接触荷重(バネ荷重)による押圧力(白抜き矢印)で、雄端子120の外周面を全方向から保持する構造である。この構造のため、従来のコネクタ100では、上下左右方向の振動(実線矢印)による力が、押圧力を越えてしまうと、雄端子120が上下左右方向に動いて雌端子110との間に相対的な動きが生じる。   As shown in FIG. 5B, the conventional connector 100 has a pressing force (white arrow) due to a contact load (spring load) of a plurality of spring parts 133 (eight in the drawing) constituting the elastic member 130. The outer peripheral surface of the male terminal 120 is held from all directions. Due to this structure, in the conventional connector 100, when the force due to the vibration in the vertical and horizontal directions (solid arrows) exceeds the pressing force, the male terminal 120 moves in the vertical and horizontal directions and is relative to the female terminal 110. Moves.

これに対し、本実施形態のコネクタ1は、図5(a)に示すように、弾性部材30を構成する3本のバネ部33の接触荷重(バネ荷重)による押圧力(白抜き矢印)で、雄端子20の外周面の第1領域(図面では下側領域)を保持する構造である。加えて、本実施形態のコネクタ1は、雌端子10に設けられた2つの前側突起部11aまたは2つの後側突起部11bで、雄端子20の外周面の第2領域(図面では上側領域)を保持する構造である。つまり、弾性部材30が、雌端子10の円筒部11に挿入された雄端子20を、前側突起部11aおよび後側突起部11bの方へ付勢する。この構造により、図5(a)左図のように、左右方向の振動(実線矢印)による力が押圧力を越えたとしても、本実施形態のコネクタ1では、2つの前側突起部11aまたは2つの後側突起部11bによって雄端子20を挟み込んで左右方向の動きを規制する。また、この構造により、図5(a)右図のように、上下方向の振動(実線矢印)による力が押圧力を越えたとしても、本実施形態のコネクタ1では、2つの前側突起部11aまたは2つの後側突起部11bによって雄端子20の上方向の動きを規制する。よって、上下左右方向の振動に対して、本実施形態のコネクタ1は、雄端子20が上下左右方向に動いて雌端子10との間に相対的な動きが生じることを抑制できる。   On the other hand, as shown in FIG. 5A, the connector 1 of the present embodiment has a pressing force (white arrow) due to a contact load (spring load) of the three spring portions 33 constituting the elastic member 30. The first terminal area (the lower area in the drawing) of the outer peripheral surface of the male terminal 20 is held. In addition, the connector 1 of the present embodiment has two front protrusions 11a or two rear protrusions 11b provided on the female terminal 10, and a second region (upper region in the drawing) of the outer peripheral surface of the male terminal 20. Is a structure that holds That is, the elastic member 30 biases the male terminal 20 inserted into the cylindrical portion 11 of the female terminal 10 toward the front protrusion 11a and the rear protrusion 11b. With this structure, as shown in the left diagram of FIG. 5A, even if the force caused by the vibration in the left-right direction (solid arrow) exceeds the pressing force, the connector 1 of this embodiment has two front protrusions 11a or 2 The male terminal 20 is sandwiched between the two rear protrusions 11b to restrict the movement in the left-right direction. Further, with this structure, as shown in the right diagram of FIG. 5A, even if the force caused by the vertical vibration (solid arrow) exceeds the pressing force, the connector 1 of this embodiment has two front protrusions 11a. Alternatively, the upward movement of the male terminal 20 is restricted by the two rear protrusions 11b. Therefore, the connector 1 of this embodiment can suppress the relative movement between the female terminal 10 due to the male terminal 20 moving in the vertical and horizontal directions with respect to the vibration in the vertical and horizontal directions.

(3)こじり方向の振動に対する作用
こじり方向の振動とは、雌端子10へ挿入した雄端子20の導体バレル部22側を上下に動かす方向に生じる振動である。このこじり方向の振動では、雄端子20の軸心は、ねじれ方向に移動する。
(3) Action on the vibration in the twisting direction The vibration in the twisting direction is a vibration generated in a direction in which the conductor barrel portion 22 side of the male terminal 20 inserted into the female terminal 10 is moved up and down. With this twisting vibration, the axis of the male terminal 20 moves in the twisting direction.

従来のコネクタ100は、図6(b)に示すように、弾性部材130を構成する複数本のバネ部133の接触荷重(バネ荷重)による押圧力(白抜き矢印)で、雄端子120の中央部の外周面を全方向から保持する構造である。この構造のため、従来のコネクタ100では、雄端子120の中央部以外の箇所で雄端子20と雌端子10(弾性部材30)との間に隙間(クリアランス)が存在する。よって、こじり方向の振動(実線矢印)が生じると、この隙間内において雄端子20が動いてしまい、雌端子10との間に相対的な動きが生じる。   As shown in FIG. 6 (b), the conventional connector 100 has a pressing force (white arrow) due to a contact load (spring load) of a plurality of spring parts 133 constituting the elastic member 130, and the center of the male terminal 120. It is the structure which holds the outer peripheral surface of a part from all directions. Due to this structure, in the conventional connector 100, there is a gap (clearance) between the male terminal 20 and the female terminal 10 (elastic member 30) at a place other than the central portion of the male terminal 120. Accordingly, when vibration in the twisting direction (solid arrow) occurs, the male terminal 20 moves in the gap, and a relative movement occurs between the female terminal 10 and the male terminal 20.

これに対し、本実施形態のコネクタ1は、図6(a)に示すように、弾性部材30を構成する3本のバネ部33の接触荷重(バネ荷重)による押圧力で、雄端子20の中央部の外周面の第1領域(図面では下側領域)を保持する構造である。加えて、本実施形態のコネクタ1は、雌端子10に設けられた前側突起部11aと後側突起部11bとで、雄端子20の中央部より外側となる外周面の第2領域(図面では上側領域)を保持する構造である。つまり、弾性部材30が、雌端子10の円筒部11に挿入された雄端子20を、前側突起部11aおよび後側突起部11bの方へ付勢する。この構造により、図6(a)上図のように、上こじり方向の振動(実線矢印)が生じても、本実施形態のコネクタ1では、前側突起部11aと弾性部材30とによって雄端子20を保持することで上こじり方向の動きを規制する。また、この構造により、図6(a)下図のように、下こじり方向の振動(実線矢印)が生じても、本実施形態のコネクタ1では、後側突起部11bと弾性部材30とによって雄端子20を保持することで上こじり方向の動きを規制する。よって、こじり方向の振動に対して、本実施形態のコネクタ1は、雄端子20がこじり方向に動いて雌端子10との間に相対的な動きが生じることを抑制できる。   On the other hand, as shown in FIG. 6A, the connector 1 of the present embodiment has a male terminal 20 with a pressing force caused by a contact load (spring load) of the three spring portions 33 constituting the elastic member 30. This is a structure that holds the first region (the lower region in the drawing) of the outer peripheral surface of the central portion. In addition, the connector 1 according to the present embodiment includes a front region 11a and a rear region 11b provided on the female terminal 10, and a second region (in the drawing) on the outer peripheral surface that is outside the center of the male terminal 20. This is a structure that holds the upper region). That is, the elastic member 30 biases the male terminal 20 inserted into the cylindrical portion 11 of the female terminal 10 toward the front protrusion 11a and the rear protrusion 11b. With this structure, as shown in the upper diagram of FIG. 6A, the male terminal 20 is formed by the front protruding portion 11 a and the elastic member 30 in the connector 1 of the present embodiment even if vibration in the upward direction (solid arrow) occurs. The movement in the upward direction is restricted by holding In addition, with this structure, as shown in the lower diagram of FIG. 6A, even if vibration in the downward twisting direction (solid arrow) occurs, the connector 1 of the present embodiment has the male projections 11b and the elastic member 30 to provide Holding the terminal 20 restricts the movement in the upward prying direction. Therefore, the connector 1 of the present embodiment can suppress the relative movement between the male terminal 20 and the female terminal 10 caused by the male terminal 20 moving in the twisting direction with respect to the vibration in the twisting direction.

[実施形態の効果]
以上のように、本発明のコネクタ1によれば、雄端子20と嵌合する雌端子10の円筒部11の内壁に、内側に突出した前側突起部11aおよび後側突起部11bを形成する。また、前側突起部11aおよび後側突起部11bと円筒部11の軸心を挟んで反対側に、弾性部材30を構成する弾性力を持つバネ部33を配置する。そして、この前側突起部11aおよび後側突起部11bと、弾性部材30のバネ部33とによって、雌端子10の円筒部11に嵌合された雄端子20を狭持する。つまり、弾性部材30が、雌端子10の円筒部11に挿入された雄端子20を、前側突起部11aおよび後側突起部11bの方へ付勢する。これにより、コネクタ1へ印加される振動の大きさが雄端子20を保持する押圧力を越えても、前側突起部11aおよび後側突起部11bによって動きが規制される。従って、雌端子10に対する雄端子20の相対的な動きを抑制できる。さらに、雄端子20と雌端子10(弾性部材30)との間の接点摺動が生じ、接点磨耗による抵抗値が増大するおそれを低減させることができる。
[Effect of the embodiment]
As described above, according to the connector 1 of the present invention, the front protrusion 11 a and the rear protrusion 11 b protruding inward are formed on the inner wall of the cylindrical portion 11 of the female terminal 10 that fits with the male terminal 20. In addition, a spring portion 33 having an elastic force constituting the elastic member 30 is disposed on the opposite side across the axial center of the cylindrical portion 11 with respect to the front protruding portion 11a and the rear protruding portion 11b. Then, the male terminal 20 fitted to the cylindrical portion 11 of the female terminal 10 is sandwiched by the front and rear protruding portions 11a and 11b and the spring portion 33 of the elastic member 30. That is, the elastic member 30 biases the male terminal 20 inserted into the cylindrical portion 11 of the female terminal 10 toward the front protrusion 11a and the rear protrusion 11b. Thereby, even if the magnitude of the vibration applied to the connector 1 exceeds the pressing force for holding the male terminal 20, the movement is restricted by the front protrusion 11a and the rear protrusion 11b. Therefore, the relative movement of the male terminal 20 with respect to the female terminal 10 can be suppressed. Further, the contact sliding between the male terminal 20 and the female terminal 10 (elastic member 30) occurs, and the possibility that the resistance value due to contact wear increases may be reduced.

なお、上述した本実施形態に係るコネクタ1は、略円筒形状の雌端子10に略円筒形状の雄端子20を挿入する、いわゆる丸ピン型端子によるコネクタ構造である。この構造の場合、弾性部材30が雌端子10に与える接触荷重が同じであっても、円筒部11の内壁に形成する前側突起部11aおよび後側突起部11bの位置を変えることで、前側突起部11aおよび後側突起部11bが雌端子10に与える接触荷重を変化させることができる。例えば、図7を参照。よって、弾性部材30を設計変更することなく、必要とする接触荷重を設定することができる。   Note that the connector 1 according to the present embodiment described above has a so-called round pin type connector structure in which a substantially cylindrical male terminal 20 is inserted into a substantially cylindrical female terminal 10. In the case of this structure, even if the contact load applied to the female terminal 10 by the elastic member 30 is the same, by changing the positions of the front projection 11a and the rear projection 11b formed on the inner wall of the cylindrical portion 11, the front projection The contact load applied to the female terminal 10 by the portion 11a and the rear projection 11b can be changed. For example, see FIG. Therefore, the required contact load can be set without changing the design of the elastic member 30.

[Modification 1]
FIG. 8A is a side sectional view of the female terminal 10 alone in the connector according to the first modification. FIG. 8B is a side cross-sectional view when the female terminal 10 and the male terminal 20 are fitted in the connector according to the first modification. FIG.8 (c) is the EE sectional view taken on the line in Fig.8 (a). FIG.8 (d) is the FF sectional view taken on the line in FIG.8 (b).

この変形例1に係るコネクタでは、円筒部11の内側に形成される2つの前側突起部11aおよび2つの後側突起部11bの代わりとして、円筒部11の軸心方向に延びかつ内側に突出した2つのビード部11cを用いている。2つのビード部11cは、円筒部11の軸心と垂直かつ所定のなす角で軸心上の一点から伸びる二本の直線が筒部の内壁と交わる位置に、軸心と平行に設けられる。さらに、変形例1に係るコネクタでは、弾性部材30の枠部31および32が、環状ではなく半円状に形成されている。この枠部31および32は、ビード部11cに干渉しない範囲に形成されればよく、その形状は図示した半円状に限られない。このような形状の弾性部材30は、図示しない保持機構によって、円筒部11の内部に組み込まれる。   In the connector according to the first modification, instead of the two front protrusions 11a and the two rear protrusions 11b formed inside the cylindrical part 11, it extends in the axial direction of the cylindrical part 11 and protrudes inward. Two bead portions 11c are used. The two bead portions 11c are provided in parallel to the shaft center at a position where two straight lines extending from one point on the shaft center at a predetermined angle and perpendicular to the shaft center of the cylindrical portion 11 intersect the inner wall of the tube portion. Furthermore, in the connector according to the first modification, the frame portions 31 and 32 of the elastic member 30 are formed in a semicircular shape instead of an annular shape. The frame portions 31 and 32 may be formed in a range that does not interfere with the bead portion 11c, and the shape thereof is not limited to the illustrated semicircular shape. The elastic member 30 having such a shape is incorporated into the cylindrical portion 11 by a holding mechanism (not shown).

上記変形例1の構造では、雌端子10に嵌合する雄端子20を、2つのビード部11cと弾性部材30のバネ部33とで押圧して保持することができる。よって、変形例1に係るコネクタでも、上述した実施形態の効果を同様に奏することができる。   In the structure of the first modification, the male terminal 20 fitted to the female terminal 10 can be pressed and held by the two bead portions 11 c and the spring portion 33 of the elastic member 30. Therefore, the effect of the above-described embodiment can be similarly achieved with the connector according to the first modification.

この変形例2に係るコネクタでは、弾性部材30のバネ部33として、枠部31および32の軸心側に湾曲した凸部33aを2箇所に形成した形状を用いている。なお、凸部33aは、3箇所以上に形成しても構わない。   In the connector according to the second modification, as the spring portion 33 of the elastic member 30, a shape in which convex portions 33a curved on the axial center side of the frame portions 31 and 32 are formed in two places is used. In addition, you may form the convex part 33a in three or more places.

上記変形例2の構造では、雌端子10に嵌合する雄端子20を弾性部材30の複数の凸部33aで押圧して保持することができる。よって、変形例2に係るコネクタでも、上述した実施形態の効果を同様に奏することができる。   In the structure of the second modification, the male terminal 20 fitted to the female terminal 10 can be pressed and held by the plurality of convex portions 33 a of the elastic member 30. Therefore, the effect of the above-described embodiment can be similarly achieved with the connector according to the second modification.

FIG. 10A is a side sectional view of the female terminal 10 alone in the connector according to the third modification. FIG. 10B is a side cross-sectional view of the connector according to Modification 3 when the female terminal 10 and the male terminal 20 are fitted. FIG.10 (c) is the II sectional view taken on the line in Fig.10 (a). FIG.10 (d) is the JJ sectional view taken on the line in FIG.10 (b).

この変形例3に係るコネクタでは、弾性部材30のバネ部33の代わりとして、円筒部11の一部を円筒部11の軸心側に弾性力を持つように切り起こして形成された、切り起こしバネ部11dを用いている。   In the connector according to the third modification, instead of the spring portion 33 of the elastic member 30, a cut and raised portion formed by cutting and raising a part of the cylindrical portion 11 so as to have an elastic force on the axial center side of the cylindrical portion 11. The spring part 11d is used.

上記変形例3の構造では、雌端子10に嵌合する雄端子20を、切り起こしバネ部11dで押圧して保持することができる。よって、変形例3に係るコネクタでも、上述した実施形態の効果を同様に奏することができる。   In the structure of the modification 3, the male terminal 20 fitted to the female terminal 10 can be cut and raised by the spring portion 11d and held. Therefore, the connector according to the third modification can also achieve the effects of the above-described embodiment in the same manner.

[その他の変形例]

In the above-described embodiment, the connector structure by the combination of the round pin type male terminal and the cylindrical type female terminal has been described. However, in addition to this structure, a connector structure using triangular pin terminals (FIG. 11A) or a connector structure using square pin terminals (FIG. 11A) may be used. Further, a connector structure (FIG. 11C) may be formed by combining a triangular pin type female terminal and a round pin type male terminal.
