Description

本発明は、複数の電線を備えた配線部品に関する。 The present invention relates to a wiring component including a plurality of electric wires.

従来、複数の電線を備えた配線部品が、接続対象間を電気的に接続するために用いられている（例えば、特許文献１参照）。 Conventionally, a wiring component including a plurality of electric wires has been used to electrically connect the connection objects (see, for example, Patent Document 1).

特許文献１に記載の配線部品は、３本の電線（動力線）を備え、接続対象である三相モータと端子台とを接続する。３本の電線のそれぞれの一端部には端子が圧着され、この端子が端子台に接続される。３本の電線のそれぞれの他端部は、三相モータの溶接部に溶接によって接続される。 The wiring component described in Patent Document 1 includes three electric wires (power lines) and connects a three-phase motor to be connected and a terminal block. A terminal is crimped to one end of each of the three electric wires, and this terminal is connected to the terminal block. The other end of each of the three wires is welded to the welded portion of the three-phase motor.

また、特許文献１には、３本の電線が固定部材によって相互に連結されたものが第２実施形態として記載されている。この固定部材は、３本の電線のそれぞれの一部を挿通させる棒状である。３本の電線は、この固定部材によって一体化されている。 Further, Patent Document 1 describes as a second embodiment in which three electric wires are connected to each other by a fixing member. This fixing member has a rod shape through which a part of each of the three electric wires is inserted. The three electric wires are integrated by this fixing member.

配線部品の電流容量や接続対象の構成によっては、対をなす２本の電線を平行に配置した電線対を複数備えて配線部品が構成されることがある。このような複数の電線対を連結部によって一体に連結する場合、この連結部をモールド成形によって形成することが考えられる。 Depending on the current capacity of the wiring component and the configuration of the connection target, the wiring component may be configured by providing a plurality of wire pairs in which two pairs of electric wires are arranged in parallel. When such a plurality of electric wire pairs are integrally connected by a connecting portion, it is conceivable to form the connecting portion by molding.

しかし、このような連結部をモールド成形する場合、金型に注入されたモールド樹脂が対をなす２本の電線の間から漏れ出すことを防ぐため、各電線対を一対のスライド型によって挟持し、２本の電線の間の隙間を塞ぐ必要がある。 However, when molding such a connecting portion, each wire pair is sandwiched by a pair of slide molds in order to prevent the mold resin injected into the mold from leaking from between the two pairs of wires. It is necessary to close the gap between the two wires.

図７は、上記のように連結部をモールド成形する場合のスライド型の構成例を示す説明図である。図７では、第１乃至第３の電線対９１〜９３を、一対のスライド型９４，９５によって挟持する場合の構成例を示し、（ａ）は第１乃至第３の電線対９１〜９３が一対のスライド型９４，９５によって挟持された状態を、（ｂ）は第１乃至第３の電線対９１〜９３が解放された状態を、それぞれ示している。第１の電線対９１は２つの電線９１１，９１２からなり、第２の電線対９２は２つの電線９２１，９２２からなり、第３の電線対９３は２つの電線９３１，９３２からなる。 FIG. 7 is an explanatory view showing a configuration example of a slide type when the connecting portion is molded as described above. FIG. 7 shows a configuration example in which the first to third electric wire pairs 91 to 93 are sandwiched by the pair of slide types 94 and 95, and FIG. 7A shows the first to third electric wire pairs 91 to 93. The state of being sandwiched by the pair of slide types 94 and 95, and the state of (b) showing the state in which the first to third wire pairs 91 to 93 are released, respectively. The first wire pair 91 is composed of two wires 911 and 912, the second wire pair 92 is composed of two wires 921 and 922, and the third wire pair 93 is composed of two wires 931 and 932.

この場合、第１の電線対９１と第２の電線対９２との間、及び第２の電線対９２と第３の電線対９３との間には、スライド型９４，９５が移動できるだけのスペースを確保しなければならず、このことが配線部品の小型化を図る上での妨げとなっていた。 In this case, there is enough space for the slide type 94 and 95 to move between the first wire pair 91 and the second wire pair 92, and between the second wire pair 92 and the third wire pair 93. This has been an obstacle to the miniaturization of wiring parts.

そこで、本発明は、複数の電線を一体に連結する連結部をモールド成形により形成しながら、小型化を図ることが可能な配線部品を提供することを目的とする。 Therefore, an object of the present invention is to provide a wiring component capable of miniaturization while forming a connecting portion for integrally connecting a plurality of electric wires by molding.

The connecting portion includes a holder that holds a part of the conductive portion, and a resin mold portion made of a mold resin formed so as to cover the conductive portion of the portion held by the holder. The holder provides a wiring component having a plurality of intervening portions, each interposing between a pair of wires.

また、本発明は、上記課題を解決することを目的として、接続対象に接続される接続部を両端部に有する複数対の電線からなる導電部と、前記複数対の電線を一体に連結する連結部とを備えた配線部品の製造方法であって、前記導電部の一部を保持すると共に対をなす電線の間にそれぞれ介在する複数の介在部を有するホルダを準備する準備工程と、前記ホルダを前記複数の介在部が対をなす電線の間に介在するように金型に配置する配置工程と、前記金型に溶融したモールド樹脂を注入して前記ホルダに保持された部分の前記導電部を覆うように樹脂モールド部を成形して前記連結部を構成する成形工程と、を有する配線部品の製造方法を提供する。 Further, for the purpose of solving the above problems, the present invention is a connection in which a conductive portion composed of a plurality of pairs of electric wires having connection portions connected to a connection target at both ends and the plurality of pairs of electric wires are integrally connected.

The specific procedure at that time is not particularly limited, but for example, the electric wires 112, are placed on the lower mold 52 so that a part of the electric wires 112, 122, 132 is accommodated in the concave grooves 52a, 52b, 52c of the lower mold 52. This can be done by arranging 122, 132, arranging the holder 3 on the holder 3, and arranging the electric wires 111, 121, 131 on the holder 3.

上型５１には、電線１１１，１２１，１３１の一部が収容される凹溝５１ａ，５１ｂ，５１ｃが形成され、上型５１が下型５２に突き合わされると、上型５１の凹溝５１ａ，５１ｂ，５１ｃと下型５２の凹溝５２ａ，５２ｂ，５２ｃが、第１乃至第３電線対１１〜１３及びホルダ３を挟んでそれぞれ向かい合う。 The upper mold 51 is formed with recessed grooves 51a, 51b, 51c in which a part of the electric wires 111, 121, 131 is accommodated, and when the upper mold 51 is abutted against the lower mold 52, the concave groove 51a of the upper mold 51 is formed. , 51b, 51c and the concave grooves 52a, 52b, 52c of the lower mold 52 face each other with the first to third electric wire pairs 11 to 13 and the holder 3 interposed therebetween.

下型５２は、本体５２０と、電線１１２，１２２，１３２をホルダ３の第１乃至第３介在部３３〜３５にそれぞれ押し付けるピン５２１，５２２，５２３とを有している。上型５１は、本体５１０と、電線１１１，１２１，１３１をホルダ３の第１乃至第３介在部３３〜３５にそれぞれ押し付けるピン５１１，５１２，５１３とを有している。下型５２の本体５２０と上型５１の本体５１０との間には、成形工程において溶融したモールド樹脂が注入されるキャビティ５０が形成される。 The lower mold 52 has a main body 520 and pins 521, 522, 523 that press the electric wires 112, 122, and 132 against the first to third intervening portions 33 to 35 of the holder 3, respectively. The upper die 51 has a main body 510 and pins 511, 512, 513 that press the electric wires 111, 121, and 131 against the first to third intervening portions 33 to 35 of the holder 3, respectively. A cavity 50 into which the mold resin melted in the molding process is injected is formed between the main body 520 of the lower mold 52 and the main body 510 of the upper mold 51.

なお、下型５２のピン５２１〜５２３、及び上型５１のピン５１１〜５１３を省略してもよい。また、これらのピン５２１〜５２３及びピン５１１〜５１３を可動式とし、配置工程の完了後、成形工程の前もしくは成形工程の実行中に、ピン５２１〜５２３が下型５２の本体５２０に、またピン５１１〜５１３が上型５１の本体５１０に、それぞれ収容されるように構成してもよい。 The pins 521 to 523 of the lower mold 52 and the pins 511 to 513 of the upper mold 51 may be omitted.

成形工程では、下型５２の本体部５２０に設けられた注入孔５２０ａから金型５のキャビティ５０内に加熱によって溶融したモールド樹脂を注入する。この際、ホルダ３の貫通孔３０１，３０２にモールド樹脂が充填される。このモールド樹脂は、キャビティ５０内の導電部１０を覆い、固化して樹脂モールド部４となる。これにより、連結部２が形成される。ホルダ３の第１及び第２の板部３１，３２は、キャビティ５０に注入されたモールド樹脂が漏れ出すことを防ぐ側壁として機能する。 In the molding step, the mold resin melted by heating is injected into the cavity 50 of the mold 5 from the injection hole 520a provided in the main body 520 of the lower mold 52. At this time, the through holes 301 and 302 of the holder 3 are filled with the mold resin. This mold resin covers the conductive portion 10 in the cavity 50 and solidifies to become the resin mold portion 4. As a result, the connecting portion 2 is formed. The first and second plate portions 31 and 32 of the holder 3 function as side walls to prevent the mold resin injected into the cavity 50 from leaking out.

その後、下型５２から上型５１を外し、下型５２から形成された連結部２を導電部１０と共に取り出すことで、配線部品１が得られる。 After that, the wiring component 1 is obtained by removing the upper mold 51 from the lower mold 52 and taking out the connecting portion 2 formed from the lower mold 52 together with the conductive portion 10.
