<実施例1>
以下、本発明を具体化した実施例1を図1〜図3を参照して説明する。本実施例1のコネクタAは、1つのワイヤーハーネスWと、ハウジング20とを備えて構成されている。ワイヤーハーネスWは、3本の導電路10と、1つの連結体30とによって構成されている。
<Example 1>
A first embodiment of the present invention will be described below with reference to FIGS. The connector A according to the first embodiment includes a single wire harness W and a housing 20. The wire harness W is composed of three conductive paths 10 and one connecting body 30.

<導電路10>
1本の導電路10は、端子金具11と、端子金具11の後端部に接続された電線16と、電線16の外周に形成した高剛性層19とを備えて構成されている。端子金具11は、銅製の板材に曲げ加工等を施すことにより、全体として前後方向に細長く延びた形状に成形されている。端子金具11の前端側には角筒部12が形成され、端子金具11の後端側にはオープンバレル状の圧着部13が形成されている。圧着部13は、前側に配されたワイヤバレル部14と、後側に配されたインシュレーションバレル部15とから構成されている。インシュレーションバレル部15は端子金具11の後端部に位置する。
<Conductive path 10>
One conductive path 10 includes a terminal fitting 11, an electric wire 16 connected to the rear end of the terminal fitting 11, and a high-rigidity layer 19 formed on the outer periphery of the electric wire 16. The terminal fitting 11 is formed into a shape that is elongated in the front-rear direction as a whole by bending the copper plate material. A square tube portion 12 is formed on the front end side of the terminal fitting 11, and an open barrel-shaped crimping portion 13 is formed on the rear end side of the terminal fitting 11. The crimping part 13 includes a wire barrel part 14 disposed on the front side and an insulation barrel part 15 disposed on the rear side. The insulation barrel portion 15 is located at the rear end portion of the terminal fitting 11.

電線16は、導体17の外周を絶縁被覆18で全周に亘って包囲した周知形態のものである。導体17は、アルミニウム製又は銅製の複数本の素線(図示省略)を撚り合わせた周知形態の撚り線からなり、可撓性を有する。絶縁被覆18は可撓性を有する合成樹脂材料からなる。したがって、電線16は、その長さ方向と交差する方向へ自在に曲げ変形させることができるものである。電線16の前端部においては、絶縁被覆18が皮剥きされて導体17が露出した状態となっている。   The electric wire 16 has a known form in which the outer periphery of the conductor 17 is surrounded by the insulating coating 18 over the entire periphery. The conductor 17 is made of a well-known twisted wire in which a plurality of strands (not shown) made of aluminum or copper are twisted, and has flexibility. The insulating coating 18 is made of a flexible synthetic resin material. Therefore, the electric wire 16 can be freely bent and deformed in a direction intersecting the length direction. At the front end portion of the electric wire 16, the insulating coating 18 is peeled off and the conductor 17 is exposed.

電線16の前端部は、圧着部13において圧着されることにより、端子金具11の後端部に接続されている。即ち、露出した導体17は、ワイヤバレル部14にカシメ付けられることで導通可能に固着されている。また、電線16のうち絶縁被覆18で包囲された領域の前端部は、インシュレーションバレル部15にカシメ付けられることで固着されている。電線16の前端部を端子金具11の後端部の圧着部13に圧着することにより、電線16と端子金具11が接続されて導電路10が構成されている。電線16と端子金具11の圧着は、アプリケータ(自動機)を用いて行われる。   The front end portion of the electric wire 16 is connected to the rear end portion of the terminal fitting 11 by being crimped at the crimping portion 13. That is, the exposed conductor 17 is fixed to the wire barrel portion 14 so as to be conductive by caulking. Further, the front end portion of the region surrounded by the insulating coating 18 in the electric wire 16 is fixed by being caulked to the insulation barrel portion 15. By crimping the front end portion of the electric wire 16 to the crimping portion 13 at the rear end portion of the terminal fitting 11, the electric wire 16 and the terminal fitting 11 are connected to form the conductive path 10. The crimping | compression-bonding of the electric wire 16 and the terminal metal fitting 11 is performed using an applicator (automatic machine).

<ハウジング20>
ハウジング20内には、前後方向に貫通した形態の複数の端子収容室21が形成されている。各端子収容室21内には、ハウジング20の後方から導電路10の前端部(即ち、端子金具11の全体と、電線16におけるインシュレーションバレル部15の後方近傍領域)が挿入されるようになっている。端子収容室21の内壁には、挿入された端子金具11を抜止めするための弾性撓み可能なランス(図示省略)が形成されている。
<Housing 20>
A plurality of terminal accommodating chambers 21 are formed in the housing 20 so as to penetrate in the front-rear direction. In each terminal accommodating chamber 21, the front end portion of the conductive path 10 (that is, the entire region of the terminal fitting 11 and the region near the rear of the insulation barrel portion 15 in the electric wire 16) is inserted from the rear of the housing 20. ing. An elastically deflectable lance (not shown) is formed on the inner wall of the terminal accommodating chamber 21 to prevent the inserted terminal fitting 11 from being pulled out.

端子金具11を端子収容室21に挿入する過程では、ランスが角筒部12の前端と干渉して弾性撓みさせられる。そして、端子金具11が正規挿入位置に到達すると、ランスが弾性復帰して端子金具11に係止し、この係止作用によって端子金具11が抜止め状態に保持される。また、ハウジング20内には、端子収容室21同士を仕切る仕切壁22の後端部を除去することにより、複数室の端子収容室21に連通する収容空間23が形成されている。   In the process of inserting the terminal fitting 11 into the terminal accommodating chamber 21, the lance interferes with the front end of the rectangular tube portion 12 and is elastically bent. When the terminal fitting 11 reaches the normal insertion position, the lance is elastically restored and locked to the terminal fitting 11, and the terminal fitting 11 is held in a retaining state by this locking action. In addition, a housing space 23 communicating with the terminal housing chambers 21 of a plurality of chambers is formed in the housing 20 by removing the rear end portion of the partition wall 22 that partitions the terminal housing chambers 21.

端子金具11を端子収容室21に挿入する際には、作業者が、端子金具11には直に触れずに、電線16を摘むことによって導電路10に前向きの挿入力を付与する。ところが、端子金具11の挿入途中では、端子金具11がランスに当たってランスを弾性撓みさせることから、ランスの弾性復元力に起因する後向きの挿入抵抗が端子金具11に作用する。そのため、電線16が細くてその剛性が低い場合には、電線16のうち操作力を付与した部分よりも前方(端子金具11に近い側)の部分が座屈変形する虞がある。   When inserting the terminal fitting 11 into the terminal accommodating chamber 21, an operator applies a forward insertion force to the conductive path 10 by picking the electric wire 16 without directly touching the terminal fitting 11. However, during the insertion of the terminal fitting 11, the terminal fitting 11 hits the lance and elastically deflects the lance, so that a backward insertion resistance caused by the elastic restoring force of the lance acts on the terminal fitting 11. Therefore, when the electric wire 16 is thin and its rigidity is low, there is a possibility that a portion of the electric wire 16 on the front side (side closer to the terminal fitting 11) is buckled and deformed.

<高剛性層19>
電線16の座屈対策として、電線16のうち端子金具11の後端部に近い位置、即ちインシュレーションバレル部15よりも後方近傍の領域には、電線16と同心の円筒状をなす高剛性層19が形成されている。高剛性層19は、電線16の絶縁被覆18に対し全周に亘って包囲するように固着した状態で形成されている。高剛性層19の内周は、その全領域が絶縁被覆18の外周面に密着している。高剛性層19は、絶縁被覆18の前端近くまで形成されている。したがって、高剛性層19の前端部は絶縁被覆18と一緒にインシュレーションバレル部15に圧着されている。高剛性層19は、その径方向の厚さ寸法が全長に亘って一定である。また、高剛性層19の剛性は、電線16を構成する絶縁被覆18よりも高い。
<High rigidity layer 19>
As a countermeasure against buckling of the electric wire 16, a high-rigidity layer having a cylindrical shape concentric with the electric wire 16 is provided at a position near the rear end of the terminal fitting 11 in the electric wire 16, that is, in a region near the rear of the insulation barrel portion 15. 19 is formed. The high-rigidity layer 19 is formed in a state of being fixed so as to surround the entire circumference of the insulating coating 18 of the electric wire 16. The entire inner periphery of the high-rigidity layer 19 is in close contact with the outer peripheral surface of the insulating coating 18. The high-rigidity layer 19 is formed up to the vicinity of the front end of the insulating coating 18. Therefore, the front end portion of the high-rigidity layer 19 is pressure-bonded to the insulation barrel portion 15 together with the insulating coating 18. The highly rigid layer 19 has a constant thickness dimension in the radial direction over its entire length. In addition, the rigidity of the high-rigidity layer 19 is higher than that of the insulating coating 18 constituting the electric wire 16.

<連結体30>
本実施例のコネクタAは、ハウジング20に形成した複数の端子収容室21に、複数本の導電路10が個別に挿入されるのであるが、作業者が1本ずつ導電路10を摘んで端子収容室21に挿入する場合には、作業に手間と時間が掛かり、作業効率が良くない。その対策として、本実施例では、3本の導電路10を連結体30によって連結することにより、1つのワイヤーハーネスWを構成している。連結体30は、横長のブロック状をなし、端子金具11の後方における近傍に配されている。連結体30は、電線16の外周のうち高剛性層19が形成された領域に固着されており、3本の電線16が連結体30を貫通している。そして、連結体30と3つの高剛性層19は、相対変位を規制された状態に固着されている。
<Connected body 30>
In the connector A of the present embodiment, a plurality of conductive paths 10 are individually inserted into a plurality of terminal accommodating chambers 21 formed in the housing 20. When inserting into the storage chamber 21, work takes time and effort, and work efficiency is not good. As a countermeasure, in the present embodiment, one wire harness W is configured by connecting three conductive paths 10 by a connecting body 30. The connecting body 30 has a horizontally long block shape, and is arranged in the vicinity of the rear of the terminal fitting 11. The connection body 30 is fixed to a region of the outer periphery of the electric wire 16 where the high-rigidity layer 19 is formed, and the three electric wires 16 penetrate the connection body 30. The coupling body 30 and the three high-rigidity layers 19 are fixed in a state where relative displacement is restricted.

また、高剛性層19は、電線16の座屈変形を規制しているので、電線16のうち高剛性層19で補強された領域(つまり、端子金具11の圧着部13に圧着された領域から、圧着部13よりも後方の所定領域に至る範囲)は、殆ど曲がらずに直線状を保つ。この連結体30と高剛性層19とにより、3本の導電路10の端子金具11は、それらの挿入対象である3室の端子収容室21と同じ配置となるような位置関係で位置決めされる。本実施例では、横一列に並ぶ3室の端子収容室21と対応するように、3本の導電路10の端子金具11が、横一列に、且つ端子収容室21の配列ピッチと同じピッチで位置決めされる。   In addition, since the high-rigidity layer 19 regulates the buckling deformation of the electric wire 16, the region of the electric wire 16 reinforced by the high-rigidity layer 19 (that is, from the region crimped to the crimping portion 13 of the terminal fitting 11). The range extending to the predetermined area behind the crimping part 13) is kept in a straight line with almost no bending. By this connection body 30 and the high-rigidity layer 19, the terminal fittings 11 of the three conductive paths 10 are positioned in a positional relationship such that they are arranged in the same manner as the three terminal receiving chambers 21 into which they are inserted. . In the present embodiment, the terminal fittings 11 of the three conductive paths 10 are arranged in a horizontal row at the same pitch as the arrangement pitch of the terminal storage chambers 21 so as to correspond to the three terminal storage chambers 21 arranged in a horizontal row. Positioned.

<光硬化性樹脂>
高剛性層19と連結体30は、光硬化性樹脂からなる。光硬化性樹脂は、モノマーとオリゴマーと光重合開始剤(光開始剤)と各種添加剤から構成されている。光硬化性樹脂は、液体の状態で光が照射されると、光エネルギーにより硬化する。高剛性層19用の光硬化性樹脂の添加剤としては、硬化後に、電線16に要求される座屈強度に応じて所定の剛性が得られるような材料が選定されている。また、連結体30用の光硬化性樹脂の添加剤としては、硬化後に、3本の導電路10を位置決めした状態で確実に連結するための必要な強度と剛性が得られるような材料が選定されている。また、光硬化性樹脂としては、大きく分けて紫外線硬化性樹脂と可視光線硬化性樹脂があるが、本実施例では高剛性層19及び連結体30の材料として紫外線硬化性樹脂が用いられている。
<Photocurable resin>
The high-rigidity layer 19 and the connection body 30 are made of a photocurable resin. The photocurable resin includes a monomer, an oligomer, a photopolymerization initiator (photoinitiator), and various additives. The photocurable resin is cured by light energy when irradiated with light in a liquid state. As an additive for the photo-curable resin for the high-rigidity layer 19, a material that can obtain a predetermined rigidity according to the buckling strength required for the electric wire 16 after curing is selected. In addition, as the additive for the photo-curable resin for the connection body 30, a material that can provide the necessary strength and rigidity for securely connecting the three conductive paths 10 in a state of being positioned after the curing is selected. Has been. In addition, the photocurable resin is roughly classified into an ultraviolet curable resin and a visible light curable resin. In this embodiment, an ultraviolet curable resin is used as a material for the high-rigidity layer 19 and the connection body 30. .

高剛性層19及び連結体30の材料として紫外線硬化性樹脂を用いる理由は、次の通りである。電線16と端子金具11の圧着工程はアプリケータにより自動化されているが、このアプリケータに光硬化用の設備を付設した自動機(図示省略)を用いることにより、圧着工程と連続して高剛性層19を形成するための光硬化工程及び連結体30を形成して導電路10を連結するための光硬化工程の自動化を図ることが可能である。圧着工程は短時間で行われるため、圧着工程と2つの光硬化工程を連続的に自動処理するためには、光硬化工程に要する時間も短縮化することが望ましい。光硬化性樹脂の硬化時間は、受ける光エネルギーの密度が高いほど短い。そして、紫外線は、可視光線に比べて光エネルギーの密度が高い。したがって、可視光線硬化性樹脂よりも硬化時間の短い紫外線硬化性樹脂を用いた。   The reason why the ultraviolet curable resin is used as the material of the high-rigidity layer 19 and the connection body 30 is as follows. The crimping process of the electric wires 16 and the terminal fittings 11 is automated by an applicator. However, by using an automatic machine (not shown) provided with a photo-curing facility on the applicator, it has high rigidity continuously with the crimping process. It is possible to automate the photocuring process for forming the layer 19 and the photocuring process for forming the coupling body 30 to connect the conductive paths 10. Since the crimping process is performed in a short time, it is desirable to shorten the time required for the photocuring process in order to continuously and automatically process the crimping process and the two photocuring processes. The curing time of the photocurable resin is shorter as the density of received light energy is higher. Ultraviolet light has a higher density of light energy than visible light. Therefore, an ultraviolet curable resin having a shorter curing time than a visible light curable resin was used.

<自動機による導電路10の製造工程及び連結工程>
自動機(図示省略)による導電路10の製造工程及び連結工程を説明する。導電路10の製造は、1本ずつ、皮剥き工程、光硬化工程、圧着工程を順に経て行われる。皮剥き工程では、電線16の前端部の絶縁被覆18を除去して導体17の前端部を露出させる。光硬化工程では、まず、電線16が、モールド型に供給されて、長さ方向に位置決めされた状態でセットされる。次いで、モールド型内に液体状の光硬化性樹脂(紫外線硬化性樹脂)が注入され、その後、モールド型内の液状光硬化性樹脂に紫外線が照射される。
<Manufacturing process and connecting process of conductive path 10 by automatic machine>
A manufacturing process and a connecting process of the conductive path 10 by an automatic machine (not shown) will be described. The conductive path 10 is manufactured one by one through a peeling process, a photocuring process, and a crimping process in order. In the skinning process, the insulating coating 18 on the front end portion of the electric wire 16 is removed to expose the front end portion of the conductor 17. In the photocuring step, first, the electric wires 16 are supplied to the mold and set in a state of being positioned in the length direction. Next, a liquid photocurable resin (ultraviolet curable resin) is injected into the mold, and then the liquid photocurable resin in the mold is irradiated with ultraviolet rays.

紫外線を照射すると、光硬化性樹脂が速やかに硬化し、高剛性層19が絶縁被覆18の外周に固着した状態でモールド成形される。圧着工程では、端子金具11が所定の圧着位置に供給されてアンビルに載置され、次いで、導体17の前端部を露出させた電線16が、端子金具11の圧着部13にセットされる。その後、クリンパが下降することにより、圧着部13が電線16を包囲するようにカシメ付けられ、電線16と端子金具11が接続されて、1本の導電路10の製造が完了する。   When the ultraviolet ray is irradiated, the photo-curing resin is rapidly cured, and the high-rigidity layer 19 is molded in a state of being fixed to the outer periphery of the insulating coating 18. In the crimping step, the terminal fitting 11 is supplied to a predetermined crimping position and placed on the anvil, and then the electric wire 16 exposing the front end portion of the conductor 17 is set on the crimping portion 13 of the terminal fitting 11. Thereafter, when the crimper descends, the crimping portion 13 is crimped so as to surround the electric wire 16, the electric wire 16 and the terminal fitting 11 are connected, and the production of one conductive path 10 is completed.

製造された導電路10は、連結用モールド型(図示省略)にセットされる。3本の導電路10が連結用モールド型にセットされたら、連結用モールド型内に液体状の光硬化性樹脂(紫外線硬化性樹脂)が注入され、その後、連結用モールド型内の液状光硬化性樹脂に紫外線が照射される。紫外線の照射により光硬化性樹脂が速やかに硬化し、連結体30が3つの高剛性層19の外周に固着した状態でモールド成形される。光硬化性樹脂が硬化すると、3本の導電路10が連結体30によって連結された状態となり、ワイヤーハーネスWが構成される。   The manufactured conductive path 10 is set in a connecting mold (not shown). When the three conductive paths 10 are set in the connecting mold, a liquid photocurable resin (ultraviolet curable resin) is injected into the connecting mold, and then liquid photocuring in the connecting mold is performed. UV light is irradiated to the functional resin. The photocurable resin is quickly cured by the irradiation of the ultraviolet rays, and is molded in a state where the connection body 30 is fixed to the outer periphery of the three high-rigidity layers 19. When the photocurable resin is cured, the three conductive paths 10 are connected by the connecting body 30, and the wire harness W is configured.

本実施例のコネクタAは、複数の端子収容室21が形成されたハウジング20と、端子金具11の後端部に電線16を接続した形態であり、ハウジング20の後方から複数の端子収容室21に個別に挿入される複数の導電路10と、光硬化性樹脂からなり、端子金具11よりも後方の領域において電線16に対し相対変位を規制された状態で設けられることで、複数の導電路10同士を連結する連結体30とを備えている。複数本の導電路10を連結体30で連結することによって、1つのワイヤーハーネスWが構成されている。したがって、連結体30に前向きの挿入力を付与すれば、連結体30を介して連結された複数の導電路10を、ワンアクションで複数の端子収容室21に挿入することができる。よって、複数本の導電路10をハウジング20に挿入する際の作業性に優れている。
<Operation and effect of embodiment>
The connector A of the present embodiment has a configuration in which the electric wire 16 is connected to the housing 20 in which a plurality of terminal accommodating chambers 21 are formed and the rear end portion of the terminal fitting 11, and the plurality of terminal accommodating chambers 21 from the rear of the housing 20. A plurality of conductive paths made of a photo-curing resin and provided with a relative displacement restricted with respect to the electric wires 16 in a region behind the terminal fitting 11. 10 is provided. One wire harness W is configured by connecting a plurality of conductive paths 10 with a connecting body 30. Therefore, if a forward insertion force is applied to the connection body 30, the plurality of conductive paths 10 connected via the connection body 30 can be inserted into the plurality of terminal accommodating chambers 21 with one action. Therefore, the workability when inserting the plurality of conductive paths 10 into the housing 20 is excellent.

また、電線16の外周のうち端子金具11の後端から連結体30に至る領域には、連結体30に対して相対変位を規制された光硬化性樹脂からなる高剛性層19が形成されている。この構成によれば、連結体30と端子金具11との間において電線16が座屈変形することが規制されるので、導電路10の挿入作業性に優れている。   Further, a high-rigidity layer 19 made of a photocurable resin whose relative displacement is restricted with respect to the connection body 30 is formed in a region from the rear end of the terminal fitting 11 to the connection body 30 in the outer periphery of the electric wire 16. Yes. According to this configuration, since the electric wire 16 is restricted from buckling deformation between the connecting body 30 and the terminal fitting 11, the insertion workability of the conductive path 10 is excellent.

また、連結体30が、紫外線硬化性樹脂からなっているので、可視光線に比べて光エネルギーの密度が高い紫外線により、光硬化性樹脂を短時間で効果的に硬化させることができる。また、本実施例のコネクタAは、導電路10が端子収容室21に挿入された状態では、連結体30の全体がハウジング20内に形成した収容空間23内に収容されるようになっている。この構成によれば、ハウジング20に対する連結体30の位置関係に基づいて、導電路10が正しく挿入されたか否かを判別することが可能である。   Moreover, since the connection body 30 consists of ultraviolet curable resin, a photocurable resin can be effectively hardened in a short time with the ultraviolet-ray whose density of optical energy is high compared with visible light. Further, the connector A of the present embodiment is configured such that the entire connecting body 30 is accommodated in the accommodating space 23 formed in the housing 20 in a state where the conductive path 10 is inserted into the terminal accommodating chamber 21. . According to this configuration, it is possible to determine whether or not the conductive path 10 is correctly inserted based on the positional relationship of the coupling body 30 with respect to the housing 20.
