第１ケーブル１２の一端部には、第１圧着端子２２が取り付けられている。また、第２ケーブル１４の一端部には、第２圧着端子２４が取り付けられている。第１圧着端子２２の第１先端部２２ｂには、第１取付孔２２ａが形成されている。また、第２圧着端子２４の第２先端部２４ｂには、第２取付孔２４ａが形成されている。第１取付孔２２ａおよび第２取付孔２４ａは、丸孔であってよい。 A first crimp terminal 22 is attached to one end of the first cable 12. A second crimp terminal 24 is attached to one end of the second cable 14. A first attachment hole 22 a is formed in the first tip portion 22 b of the first crimp terminal 22. A second attachment hole 24 a is formed in the second tip portion 24 b of the second crimp terminal 24. The first mounting hole 22a and the second mounting hole 24a may be round holes.

本実施形態に係る中継コネクタ１０は、絶縁性の基台１６と、基台１６の内部に設置された導電性の板バネ１８と、固定用支柱２０とを備える。 The relay connector 10 according to this embodiment includes an insulating base 16, a conductive leaf spring 18 installed inside the base 16, and a fixing column 20.

基台１６は、樹脂材料で形成された直方体形状の物体である。基台１６の第１側面１６ａには、第１ケーブル１２の第１圧着端子２２を挿入するための第１挿入孔１６ｃが形成されている。基台１６の第１側面１６ａと対向する第２側面１６ｂには、第２ケーブル１４の第２圧着端子２４を挿入するための第２挿入孔１６ｄが形成されている。 The base 16 is a rectangular parallelepiped object formed of a resin material. A first insertion hole 16 c for inserting the first crimp terminal 22 of the first cable 12 is formed in the first side surface 16 a of the base 16. A second insertion hole 16 d for inserting the second crimp terminal 24 of the second cable 14 is formed in the second side surface 16 b facing the first side surface 16 a of the base 16.

図５は、基台１６の一部を示す。図５に示すように、本実施形態において、基台１６は、第１分割基台５０と第２分割基台５１とを結合することにより形成される。このように基台１６を分割構成とすることにより、容易に基台１６内に板バネ１８を組み込むことができる。図５に示すように、第１分割基台５０の端部には凸部５０ａが形成されており、第２分割基台５１の端部には凹部５１ａが形成されている。この凸部５０ａと凹部５１ａとを嵌合することにより、第１分割基台５０と第２分割基台５１とが結合される。なお、基台１６は分割構成に限定されず、一体的に構成されてもよい。基台１６を一体構成とする場合、板バネ１８を基台１６の側面から嵌め入れる構成をとることができる。 FIG. 5 shows a part of the base 16. As shown in FIG. 5, in the present embodiment, the base 16 is formed by joining a first divided base 50 and a second divided base 51. Thus, by making the base 16 into a divided configuration, the leaf spring 18 can be easily incorporated into the base 16. As shown in FIG. 5, a convex portion 50 a is formed at the end of the first split base 50, and a concave portion 51 a is formed at the end of the second split base 51. The first divided base 50 and the second divided base 51 are coupled by fitting the convex portion 50a and the concave portion 51a. In addition, the base 16 is not limited to a division | segmentation structure, You may be comprised integrally. In the case where the base 16 is configured integrally, a configuration in which the leaf spring 18 is fitted from the side surface of the base 16 can be employed.

図６は、板バネ１８を示す。板バネ１８は、一枚の金属板を折り曲げ加工することにより形成される。板バネ１８は、導電性が高く且つバネ性が高い材質を用いて形成される。好適な材質としては、りん青銅を例示できる。 FIG. 6 shows the leaf spring 18. The leaf spring 18 is formed by bending a single metal plate. The leaf spring 18 is formed using a material having high conductivity and high spring property. An example of a suitable material is phosphor bronze.

板バネ１８は、第１ケーブル１２の第１圧着端子２２を保持するための第１保持部１８ａと、第２ケーブル１４の第２圧着端子２４を保持するための第２保持部１８ｂとを有する。第１保持部１８ａおよび第２保持部１８ｂは、それぞれ、金属板が微小な隙間を挟んで重なり合うように形成されている。第１保持部１８ａと第２保持部１８ｂは、圧着端子の先端部の挿入口が互いに反対方向を向くように形成される。 The leaf spring 18 has a first holding portion 18 a for holding the first crimping terminal 22 of the first cable 12 and a second holding portion 18 b for holding the second crimping terminal 24 of the second cable 14. . The first holding part 18a and the second holding part 18b are formed so that the metal plates overlap each other with a minute gap therebetween. The 1st holding | maintenance part 18a and the 2nd holding | maintenance part 18b are formed so that the insertion port of the front-end | tip part of a crimp terminal may face the mutually opposite direction.

圧着端子を保持していない状態において、金属板間の隙間は、圧着端子の先端部の厚さよりも小さい。金属板間に圧着端子の先端部が挿入されると、金属板間の隙間が拡開される。第１保持部１８ａ、第２保持部１８ｂは、それぞれ、第１圧着端子２２の第１先端部２２ｂ、第２圧着端子２４の第２先端部２４ｂを挟み込むよう弾性的に付勢されている。第１圧着端子２２の第１先端部２２ｂが第１保持部１８ａに狭持され、第２圧着端子２４の第２先端部２４ｂが第２保持部１８ｂに狭持されることにより、板バネ１８を介して第１ケーブル１２と第２ケーブル１４とが導通される。 In a state where the crimp terminal is not held, the gap between the metal plates is smaller than the thickness of the tip portion of the crimp terminal. When the tip end portion of the crimp terminal is inserted between the metal plates, the gap between the metal plates is widened. The first holding portion 18a and the second holding portion 18b are elastically biased so as to sandwich the first tip portion 22b of the first crimp terminal 22 and the second tip portion 24b of the second crimp terminal 24, respectively. The first tip 22b of the first crimp terminal 22 is sandwiched by the first holding portion 18a, and the second tip 24b of the second crimp terminal 24 is sandwiched by the second holding portion 18b. The first cable 12 and the second cable 14 are electrically connected via the cable.

板バネ１８は、第１分割基台５０と第２分割基台５１とを結合する際に、第１分割基台５０と第２分割基台５１との間に組み込まれる。基台１６内に装着された状態において、第１保持部１８ａの挿入口は、基台１６の第１挿入孔１６ｃに面しており、第２保持部１８ｂの挿入口は、基台１６の第２挿入孔１６ｄに面している。 The leaf spring 18 is incorporated between the first split base 50 and the second split base 51 when the first split base 50 and the second split base 51 are coupled. When mounted in the base 16, the insertion port of the first holding portion 18 a faces the first insertion hole 16 c of the base 16, and the insertion port of the second holding portion 18 b is connected to the base 16. It faces the second insertion hole 16d.

本実施形態に係る中継コネクタ１０において、基台１６および板バネ１８には、基台１６および板バネ１８を共に貫通する貫通孔３０が設けられている。この貫通孔３０は、板バネ１８の第１保持部１８ａおよび第２保持部１８ｂを貫通している。この貫通孔３０は、丸孔であってよい。貫通孔３０は、第１圧着端子２２の第１取付孔２２ａおよび第２圧着端子２４の第２取付孔２４ａと略同じ直径を有する。図４に示すように、第１圧着端子２２の第１先端部２２ｂが板バネ１８の第１保持部１８ａに挿入され、第２圧着端子２４の第２先端部２４ｂが板バネ１８の第２保持部１８ｂに挿入された状態において、貫通孔３０と第１取付孔２２ａおよび第２取付孔２４ａは連通する。すなわち、貫通孔３０と第１取付孔２２ａおよび第２取付孔２４ａは、孔の中心軸が揃うように配置される。 In the relay connector 10 according to the present embodiment, the base 16 and the leaf spring 18 are provided with through holes 30 penetrating the base 16 and the leaf spring 18 together. The through hole 30 passes through the first holding part 18 a and the second holding part 18 b of the leaf spring 18. The through hole 30 may be a round hole. The through hole 30 has substantially the same diameter as the first attachment hole 22 a of the first crimp terminal 22 and the second attachment hole 24 a of the second crimp terminal 24. As shown in FIG. 4, the first tip 22 b of the first crimp terminal 22 is inserted into the first holding portion 18 a of the leaf spring 18, and the second tip 24 b of the second crimp terminal 24 is the second of the leaf spring 18. In the state inserted in the holding part 18b, the through hole 30, the first mounting hole 22a, and the second mounting hole 24a communicate with each other. That is, the through hole 30, the first mounting hole 22a, and the second mounting hole 24a are arranged so that the central axes of the holes are aligned.

固定用支柱２０は、貫通孔３０の直径よりも若干小さい直径を有する絶縁性の棒状体である。固定用支柱２０は、例えば樹脂製であってよい。図４に示すように、固定用支柱２０は、第１圧着端子２２の第１先端部２２ｂが板バネ１８の第１保持部１８ａに挿入され、且つ第２圧着端子２４の第２先端部２４ｂが板バネ１８の第２保持部１８ｂに挿入された状態で、基台１６および板バネ１８の貫通孔３０と、第１圧着端子２２の第１取付孔２２ａおよび第２圧着端子２４の第２取付孔２４ａとを貫通するように挿入される。固定用支柱２０を挿入することにより、第１圧着端子２２および第２圧着端子２４が中継コネクタ１０に固定される。 The fixing column 20 is an insulating rod-like body having a diameter slightly smaller than the diameter of the through hole 30. The fixing column 20 may be made of resin, for example. As shown in FIG. 4, in the fixing column 20, the first tip portion 22 b of the first crimp terminal 22 is inserted into the first holding portion 18 a of the leaf spring 18 and the second tip portion 24 b of the second crimp terminal 24. Is inserted into the second holding portion 18b of the leaf spring 18, the through hole 30 of the base 16 and the leaf spring 18, the first attachment hole 22a of the first crimp terminal 22, and the second of the second crimp terminal 24. It is inserted so as to penetrate the mounting hole 24a. By inserting the fixing column 20, the first crimp terminal 22 and the second crimp terminal 24 are fixed to the relay connector 10.

本実施形態において、固定用支柱２０の上端部には鍔状部２０ａが形成されており、固定用支柱２０の下端部には傘状部２０ｂが形成されている。鍔状部２０ａおよび傘状部２０ｂは、固定用支柱２０が貫通孔３０から抜け落ちるのを防止するためのストッパ部として機能する。鍔状部２０ａおよび傘状部２０ｂは、貫通孔３０よりも大きい直径を有する。固定用支柱２０を貫通孔３０に挿入しようとすると、貫通孔３０の上端縁部３０ａによって傘状部２０ｂが内側に撓む。これにより、貫通孔３０内に固定用支柱２０を挿入可能となる。固定用支柱２０が貫通孔３０内に完全に挿入されると、鍔状部２０ａが貫通孔３０の上端縁部３０ａと係止するとともに、傘状部２０ｂが貫通孔３０の下端縁部３０ｂから外に出て外側に拡がり、貫通孔３０の下端縁部３０ｂと係止する。このように、固定用支柱２０がストッパ部を備えることにより固定用支柱２０の抜け落ちが防止され、安定的に第１ケーブル１２と第２ケーブル１４を接続できる。また、第１ケーブル１２と第２ケーブル１４を中継コネクタ１０から外す際には、傘状部２０ｂを指で摘んで内側に撓ませることで、貫通孔３０から固定用支柱２０を抜くことができる。 In the present embodiment, a hook-shaped portion 20 a is formed at the upper end portion of the fixing column 20, and an umbrella-shaped portion 20 b is formed at the lower end portion of the fixing column 20. The hook-shaped portion 20 a and the umbrella-shaped portion 20 b function as stopper portions for preventing the fixing column 20 from falling out of the through hole 30. The hook-shaped portion 20 a and the umbrella-shaped portion 20 b have a larger diameter than the through hole 30. When the fixing column 20 is to be inserted into the through hole 30, the umbrella-shaped portion 20 b is bent inward by the upper edge 30 a of the through hole 30. As a result, the fixing column 20 can be inserted into the through hole 30. When the fixing column 20 is completely inserted into the through hole 30, the hook-shaped portion 20 a is engaged with the upper end edge 30 a of the through hole 30, and the umbrella-shaped portion 20 b extends from the lower end edge 30 b of the through hole 30. It goes out and spreads outside and engages with the lower edge 30 b of the through hole 30. As described above, since the fixing support 20 includes the stopper portion, the fixing support 20 is prevented from falling off, and the first cable 12 and the second cable 14 can be stably connected. Further, when the first cable 12 and the second cable 14 are removed from the relay connector 10, the fixing column 20 can be removed from the through hole 30 by pinching the umbrella-shaped portion 20 b with a finger and bending it inward. .

以上説明したように、本実施形態に係る中継コネクタ１０によれば、第１ケーブル１２と第２ケーブル１４を電気的に接続するとともに、第１ケーブル１２と第２ケーブル１４を確実に固定することができる。第１ケーブル１２と第２ケーブル１４の接続作業は、まず基台１６に第１ケーブル１２の第１圧着端子２２と第２ケーブル１４の第２圧着端子２４を挿入し、その後貫通孔３０に固定用支柱２０を挿入するだけであるので、従来の端子台のように圧着端子をネジ止めする作業が不要となり、非常に簡易である。これにより、端子台を用いた場合よりも非常に少ない工数でケーブル同士を接続できる。 As described above, according to the relay connector 10 according to the present embodiment, the first cable 12 and the second cable 14 are electrically connected, and the first cable 12 and the second cable 14 are securely fixed. Can do. The first cable 12 and the second cable 14 are connected by first inserting the first crimp terminal 22 of the first cable 12 and the second crimp terminal 24 of the second cable 14 into the base 16 and then fixing them to the through holes 30. Since only the support column 20 is inserted, the work of screwing the crimp terminal as in the conventional terminal block is not required, which is very simple. As a result, the cables can be connected with much fewer man-hours than when a terminal block is used.

また、本実施形態に係る中継コネクタ１０によれば、基台１６の内部に導電性の第１圧着端子２２、第２圧着端子２４および板バネ１８が配置されるため、絶縁性の確保を目的とした熱収縮チューブ等を中継コネクタ１０の周囲に取り付ける必要がない。そのため、従来の端子台に比べ、大幅な工数の削減を図ることができる。 In addition, according to the relay connector 10 according to the present embodiment, the conductive first crimping terminal 22, the second crimping terminal 24, and the leaf spring 18 are disposed inside the base 16. There is no need to attach the heat-shrinkable tube or the like around the relay connector 10. Therefore, a significant reduction in man-hours can be achieved compared to the conventional terminal block.

さらに、本実施形態に係る中継コネクタ１０によれば、従来の端子台のようにネジ止めするためのスペースを確保する必要がないため、中継コネクタの小型化を図ることができる。 Furthermore, according to the relay connector 10 according to the present embodiment, it is not necessary to secure a space for screwing as in the conventional terminal block, so that the relay connector can be reduced in size.

以上、本発明を実施の形態をもとに説明した。この実施の形態は例示であり、それらの各構成要素の組合せにいろいろな変形例が可能なこと、またそうした変形例も本発明の範囲にあることは当業者に理解されるところである。 The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to the combinations of the respective constituent elements, and such modifications are also within the scope of the present invention.
