Description

本発明は、複数の電線を備えた配線部品及びその製造方法に関する。 The present invention relates to a wiring component including a plurality of electric wires and a manufacturing method thereof.

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 connection targets (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 Literature 1 includes three electric wires (power lines), and connects a three-phase motor to be connected to 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 connected to the welded portion of the three-phase motor by welding.

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。 Patent Document 1 describes a second embodiment in which three electric wires are connected to each other by a fixing member. The 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 including a plurality of wire pairs in which two electric wires forming a pair 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 between a pair of slide dies in order to prevent the mold resin injected into the mold from leaking out between the two wires forming a pair. 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 mold when the connecting portion is molded as described above. FIG. 7 shows a configuration example when the first to third electric wire pairs 91 to 93 are sandwiched by a pair of slide molds 94 and 95, and FIG. 7A shows the first to third electric wire pairs 91 to 93. (B) shows a state in which the first to third electric wire pairs 91 to 93 are released. The first electric wire pair 91 includes two electric wires 911 and 912, the second electric wire pair 92 includes two electric wires 921 and 922, and the third electric wire pair 93 includes two electric 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, a space in which the slide molds 94 and 95 can 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 components.

また、本発明は、その趣旨を逸脱しない範囲で適宜変形して実施することが可能である。例えば、上記実施の形態では、電線１１１，１１２，１２１，１２２，１３１，１３２がエナメル線からなる場合について説明したが、これに限らず、電線１１１，１１２，１２１，１２２，１３１，１３２を、銅等の良導電性の金属からなる導線が絶縁体によって被覆された絶縁電線によって構成してもよい。この場合、各電線１１１，１１２，１２１，１２２，１３１，１３２の両端部では、絶縁体が除去されて導線が露出する。 Further, the present invention can be appropriately modified and implemented without departing from the spirit of the present invention. For example, in the above embodiment, the case where the electric wires 111, 112, 121, 122, 131, 132 are made of enameled wires has been described. However, the present invention is not limited thereto, and the electric wires 111, 112, 121, 122, 131, 132 are You may comprise by the insulated wire with which the conducting wire which consists of highly conductive metals, such as copper, was coat | covered with the insulator. In this case, at both ends of each of the electric wires 111, 112, 121, 122, 131, 132, the insulator is removed and the conductive wires are exposed.
