しかしながら従来のコネクタは、車両の振動に伴って電線が振動した際に、リアホルダとハウジングが相対的に変位することで、互いに係合状態にあるリアホルダ（ホルダ）の凹状係合部及びハウジングの凸状係合部にせん断力が作用する場合があった。 However, in the conventional connector, when the electric wire vibrates due to the vibration of the vehicle, the rear holder and the housing are relatively displaced, so that the concave engaging portion of the rear holder (holder) and the convex of the housing are engaged with each other. A shearing force may act on the shape engaging portion.

本発明は、車両の振動に伴ってホルダ及びハウジングが相対的に変位することの抑制を図ったコネクタを提供することを目的とする。 An object of the present invention is to provide a connector that suppresses the relative displacement of the holder and the housing due to the vibration of the vehicle.

前記課題を解決し目的を達成するために、請求項１に記載された発明は、複数の電線の端部を収容する筒状のハウジングと、該ハウジングの端部に設けられて前記電線を保持するホルダと、を備え、前記ホルダは、前記複数の電線それぞれを挿通させる複数の電線挿通部を有して該複数の電線を挟み込むことが可能な２部材から構成されたホルダ本体と、該ホルダ本体から突出して設けられて前記ハウジングの外面を係止する係止部と、を有し、前記ホルダ本体は、前記複数の電線挿通部間に噛合い部を有し、前記噛合い部は、前記２部材のうち一方に設けられた第１噛合い部と、他方に設けられた第２噛合い部と、を有して構成され、前記第１噛合い部は、前記一方の所定面から他方に突出した複数の第１凸部と、前記複数の第１凸部間に設けられかつ前記一方の所定面に凹の第１凹部と、を有し、前記第２噛合い部は、前記他方の所定面に凹に設けられて前記第１凸部に嵌る複数の第２凹部と、前記複数の第２凹部間に設けられかつ前記他方の所定面から前記一方に突出して設けられて前記第１凹部に嵌る第２凸部と、を有していることを特徴とするコネクタである。 In order to solve the above-mentioned problems and achieve the object, the invention according to claim 1 has a tubular housing for accommodating the ends of a plurality of electric wires and a tubular housing provided at the ends of the housing to hold the electric wires. The holder is composed of a holder body composed of two members having a plurality of electric wire insertion portions through which the plurality of electric wires are inserted and capable of sandwiching the plurality of electric wires, and the holder. The holder main body has a meshing portion between the plurality of electric wire insertion portions, and the meshing portion has a locking portion that is provided so as to project from the main body and locks the outer surface of the housing. It is configured to have a first meshing portion provided on one of the two members and a second meshing portion provided on the other, and the first meshing portion is formed from the predetermined surface of the one. The second meshing portion has a plurality of first convex portions protruding from the other side and a first concave portion that is provided between the plurality of first convex portions and is concave on one of the predetermined surfaces. The said The connector is characterized by having a second convex portion that fits into the first concave portion.

請求項２に記載された発明は、請求項１に記載の発明において、前記係止部は、前記２部材が前記複数の電線を挟み込む方向の前記電線挿通部の両側に一対設けられていることを特徴とするものである。 The invention according to claim 2 is the invention according to claim 1, wherein the locking portions are provided on both sides of the electric wire insertion portion in a direction in which the two members sandwich the plurality of electric wires. It is characterized by.

請求項１に記載の発明によれば、第１噛合い部の第１凸部と第２噛合い部の第２凹部とが嵌合し、第１噛合い部の第１凹部と第２噛合い部の第２凸部とが嵌合していることにより、車両の振動に伴って電線が振動した際、ホルダ本体に作用する力が複数の電線が並ぶ方向に分散され、大きなせん断力が作用し難くされ、ホルダ本体を構成する２部材の電線が並ぶ方向の相対的な変位が抑制される。また、車両の振動により、ホルダ本体がハウジング内で変位しても、係止部がハウジングの外面を係止するように構成されていることで、ホルダのハウジングに対する係止が維持され、ホルダが電線を保持した状態を継続することができる。 According to the first aspect of the invention, the first convex portion of the first meshing portion and the second concave portion of the second meshing portion are fitted, and the first concave portion and the second meshing of the first meshing portion are fitted. Since the second convex portion of the invention is fitted, when the electric wire vibrates due to the vibration of the vehicle, the force acting on the holder body is dispersed in the direction in which the plurality of electric wires are lined up, and a large shearing force is generated. It is made difficult to act, and the relative displacement in the direction in which the electric wires of the two members constituting the holder body are lined up is suppressed. Further, even if the holder body is displaced in the housing due to the vibration of the vehicle, the locking portion is configured to lock the outer surface of the housing, so that the holder can be kept locked to the housing and the holder can be held. The state of holding the electric wire can be continued.

It is configured to have a formed facing plate 512 and a lock hole 513 provided in the facing plate 512 and into which the lock protrusion 32 of the first housing portion 3 can be fitted.

上述した構成の一対の電線２，２、シール部材４及びホルダ５を、第１ハウジング部３に収容する手順を説明する。シール部材４の一対のシール挿通部４０、４０それぞれに、各電線２を挿通（圧入）する。シール部材４は、各電線２の先端２Ｆから所定寸法だけ後方に離間した位置に装着される。そして、各電線２の先端２Ｆを、第１ハウジング部３の後端部から挿入する。さらに挿入することで、シール部材４が第１ハウジング部３の第１内部空間３０に圧入されて、シール部材４がシール収容空間３０Ａに収容される。これにより防水領域が形成される。 A procedure for accommodating the pair of electric wires 2 and 2, the seal member 4 and the holder 5 having the above-described configuration in the first housing portion 3 will be described. Each electric wire 2 is inserted (press-fitted) into each of the pair of seal insertion portions 40, 40 of the seal member 4. The seal member 4 is mounted at a position separated rearward by a predetermined dimension from the tip 2F of each electric wire 2. Then, the tip 2F of each electric wire 2 is inserted from the rear end of the first housing portion 3. By further inserting, the seal member 4 is press-fitted into the first internal space 30 of the first housing portion 3, and the seal member 4 is accommodated in the seal accommodating space 30A. This forms a waterproof area.

この後、各電線２のシール部材４の後方側にて、各電線２を挟んで上下の両側に下側挿通部５２Ａと上側挿通部５２Ｂとを位置させ、下側分割面５００Ａと上側分割面５００Ｂとを近づける。これにより、第１凸部５４Ａ１と第２凹部５４Ｂ１とが嵌合し、第１凹部５４Ａ２と第２凸部５４Ｂ２とが嵌合して、変位抑制部５４が形成される。これと略同時に、凸状係合部５３Ａと凹状係合部５３Ｂが係合する。これにより、下部材５０Ａ及び上部材５０Ｂに一対の電線２、２が挟み込まれて、下部材５０Ａの下側分割面５００Ａ及び上部材５０Ｂの上側分割面５００Ｂが接触した状態が維持される。 After that, on the rear side of the seal member 4 of each electric wire 2, the lower insertion portion 52A and the upper insertion portion 52B are positioned on both the upper and lower sides of the electric wire 2 with the lower insertion portion 52A and the upper division surface 500A and the upper division surface. Bring it closer to 500B. As a result, the first convex portion 54A1 and the second concave portion 54B1 are fitted, and the first concave portion 54A2 and the second convex portion 54B2 are fitted to form the displacement suppressing portion 54. At about the same time, the convex engaging portion 53A and the concave engaging portion 53B engage with each other. As a result, the pair of electric wires 2 and 2 are sandwiched between the lower member 50A and the upper member 50B, and the state in which the lower split surface 500A of the lower member 50A and the upper split surface 500B of the upper member 50B are in contact with each other is maintained.

この後、ホルダ５を各電線２の先端２Ｆ側に移動させ、第１ハウジング部３の後端部から挿入する。さらに挿入することで、ホルダ５の各ロックアーム５１が一対の突条部３３０、３３０間に進入し、一対の突条部３３０、３３０間で前方に案内されて、ロック孔５１３がロック突起３２に嵌合する。これと略同時に、ホルダ本体５０はホルダ収容空間３０Ｂに収容される。このようにして、一対の電線２，２、シール部材４及びホルダ５を、第１ハウジング部３に収容する。 After that, the holder 5 is moved to the tip 2F side of each electric wire 2 and inserted from the rear end portion of the first housing portion 3. By further inserting, each lock arm 51 of the holder 5 enters between the pair of ridges 330 and 330, is guided forward between the pair of ridges 330 and 330, and the lock hole 513 is locked by the lock protrusion 32. Fit into. At about the same time, the holder body 50 is housed in the holder housing space 30B. In this way, the pair of electric wires 2, 2 and the seal member 4 and the holder 5 are housed in the first housing portion 3.

上述した構成のコネクタ１によれば、下側噛合い部５４Ａ（第１噛合い部）の第１凸部５４Ａ１と上側噛合い部５４Ｂ（第２噛合い部）の第２凹部５４Ｂ１とが嵌合し、下側噛合い部５４Ａの第１凹部５４Ａ２と上側噛合い部５４Ｂの第２凸部５４Ｂ２とが嵌合していることにより、車両の振動に伴って電線２が振動した際、ホルダ本体５０に作用する力が左右方向Ｘ（複数の電線が並ぶ方向）に分散され、大きなせん断力が作用し難くなって、ホルダ本体５０を構成する２部材５０Ａ、５０Ｂの左右方向Ｘ（電線が並ぶ方向）の相対的な変位が抑制される。これによれば、下部材５０Ａ及び上部材５０Ｂの保持力強度が増加して、ホルダ５が各電線２を保持した状態を継続することができる。 According to the connector 1 having the above-described configuration, the first convex portion 54A1 of the lower meshing portion 54A (first meshing portion) and the second concave portion 54B1 of the upper meshing portion 54B (second meshing portion) are fitted. When the electric wire 2 vibrates due to the vibration of the vehicle due to the fitting of the first concave portion 54A2 of the lower meshing portion 54A and the second convex portion 54B2 of the upper meshing portion 54B, the holder The force acting on the main body 50 is dispersed in the left-right direction X (the direction in which a plurality of electric wires are lined up), and it becomes difficult for a large shearing force to act. Relative displacement in the line-up direction) is suppressed. According to this, the holding force strength of the lower member 50A and the upper member 50B is increased, and the state in which the holder 5 holds each electric wire 2 can be continued.

また、車両の振動により、ホルダ本体５０が第１ハウジング部３（ハウジング）内で変位しても、ロックアーム５１（係止部）が第１ハウジング部３の外面を係止するように構成されていることで、ホルダ５の第１ハウジング部３に対する係止が維持されて、より一層、ホルダ５が各電線２を保持した状態を継続することができる。 Further, even if the holder body 50 is displaced in the first housing portion 3 (housing) due to the vibration of the vehicle, the lock arm 51 (locking portion) is configured to lock the outer surface of the first housing portion 3. By doing so, the locking of the holder 5 to the first housing portion 3 is maintained, and the state in which the holder 5 holds each electric wire 2 can be further maintained.

また、ロックアーム５１（係止部）は、下部材５０Ａ及び上部材５０Ｂの各外面に２個ずつ設けられているとともに、各電線挿通部５２を挟んで上下の両側に設けられている。これによれば、車両の振動に伴って各電線２を介して、ホルダ本体５０を構成する２部材５０Ａ、５０Ｂに互いに離れる方向に力が作用したとしても、ロックアーム５１が電線挿通部５２を上下に挟む位置に設けられていることで、車両の振動に伴ってホルダ５及び第１ハウジング部３（ハウジング）の上下方向Ｙ（２部材５０Ａ、５０Ｂが互いに離れる方向）の相対的な変位の抑制が図られる。このように、車両の振動に伴ってホルダ５及び第１ハウジング部３（ハウジング）の左右方向Ｘ及び上下方向Ｙの変位が抑制されることにより、より一層、ホルダ５の第１ハウジング部３に対する係止が維持されて、ホルダ５が各電線２を保持した状態を継続することができる。 Further, two lock arms 51 (locking portions) are provided on each outer surface of the lower member 50A and the upper member 50B, and are provided on both upper and lower sides of the electric wire insertion portion 52. According to this, even if a force acts on the two members 50A and 50B constituting the holder body 50 in a direction away from each other via each electric wire 2 due to the vibration of the vehicle, the lock arm 51 pushes the electric wire insertion portion 52. Since it is provided at a position where it is sandwiched between the upper and lower parts, the relative displacement of the holder 5 and the first housing portion 3 (housing) in the vertical direction Y (the direction in which the two members 50A and 50B are separated from each other) due to the vibration of the vehicle. Suppression is achieved. In this way, the displacement of the holder 5 and the first housing portion 3 (housing) in the left-right direction X and the vertical direction Y is suppressed due to the vibration of the vehicle, so that the holder 5 is further relative to the first housing portion 3. The locking is maintained, and the state in which the holder 5 holds each electric wire 2 can be continued.
