Description

本発明は、電線と端子の接続構造に関する。 The present invention relates to a connection structure between an electric wire and a terminal.

図１１（ａ）〜図１１（ｅ）は、下記特許文献１に開示された電線と端子の接続構造である。
この電線と端子の接続構造は、被覆電線１００を、金属製の端子金具１１０に導通接続する構造である。 FIG. 11A to FIG. 11E are electric wire and terminal connection structures disclosed in Patent Document 1 below.
The connection structure between the electric wire and the terminal is a structure in which the covered electric wire 100 is conductively connected to the metal terminal fitting 110.

被覆電線１００は、図１１（ａ）に示すように、複数本の素線を撚り束ねた芯線１０２と、この芯線１０２の周囲を覆う絶縁被覆１０３と、を有した構造である。この被覆電線１００は、図１１（ｂ）に示すように、先端部を、偏平に押しつぶした偏平部１０５に整形する。そして、図１１（ｃ）に示すように、偏平部１０５を端子金具１１０に縦添えする。 As shown in FIG. 11A, the covered electric wire 100 has a structure having a core wire 102 in which a plurality of strands are twisted and bundled, and an insulating coating 103 covering the periphery of the core wire 102. As shown in FIG. 11B, the covered electric wire 100 shapes the tip portion into a flat portion 105 that is flattened. Then, as shown in FIG. 11 (c), the flat portion 105 is vertically attached to the terminal fitting 110.

端子金具１１０は、図１１（ｃ）に示すように、被覆電線１００を縦添え状態に載置する略棒状の電線縦添え部１１１を有している。更に、この電線縦添え部１１１の一側には、電線縦添え部１１１に縦添えされる被覆電線１００に突き刺さることで芯線１０２と導通接続状態になる突刺針部１１２が一体形成されている。突刺針部１１２は、電線縦添え部１１１の延在方向と直交する方向に突出して設けられた針状突起で、電線縦添え部１１１に縦添えされる偏平部１０５を垂直に貫通する。 As shown in FIG. 11C, the terminal fitting 110 has a substantially rod-shaped electric wire vertical attachment portion 111 on which the covered electric wire 100 is placed in the vertical attachment state. Further, a piercing needle portion 112 that is in a conductive connection state with the core wire 102 by being pierced into the covered electric wire 100 vertically attached to the electric wire vertical attachment portion 111 is integrally formed on one side of the electric wire vertical attachment portion 111. The piercing needle portion 112 is a needle-like protrusion provided so as to protrude in a direction orthogonal to the extending direction of the electric wire vertical attachment portion 111 and penetrates the flat portion 105 vertically attached to the electric wire vertical attachment portion 111 vertically.

特許文献１に開示の電線と端子の接続構造では、図１１（ｄ）に示すように、電線縦添え部１１１に縦添えすることで偏平部１０５に突刺針部１１２が貫通した状態となった被覆電線１００は、矢印Ｍ１で示すように、芯線１０２の撚り方向に電線自体を捻って、芯線１０２と突刺針部１１２との密着性を高める。次いで突刺針部１１２の貫通部位の外側に、断面コ字状の加締め金具１２０を取り付ける。 In the connection structure between the electric wire and the terminal disclosed in Patent Document 1, as shown in FIG. 11 (d), the piercing needle portion 112 penetrates the flat portion 105 by being vertically attached to the electric wire vertical attachment portion 111. The covered electric wire 100 twists the electric wire itself in the twisting direction of the core wire 102 as shown by an arrow M1, and improves the adhesion between the core wire 102 and the piercing needle portion 112. Next, a caulking fitting 120 having a U-shaped cross section is attached to the outside of the penetrating portion of the puncture needle portion 112.

加締め金具１２０は、偏平部１０５の上に被さる上壁部１２１に、偏平部１０５を貫通した突刺針部１１２の先端を挿通させる針通し穴１２２が貫通形成されている。また、上壁部１２１の後端側内面には、被覆電線１００の外周を位置決めする円弧面状の電線押え部１２３が形成されている。 In the caulking metal fitting 120, a needle through hole 122 is formed through the upper wall portion 121 that covers the flat portion 105 so that the tip of the piercing needle portion 112 that passes through the flat portion 105 is inserted therethrough. Further, on the inner surface of the rear end side of the upper wall portion 121, an arc-shaped wire pressing portion 123 for positioning the outer periphery of the covered wire 100 is formed.

特許文献１の電線と端子の接続構造では、図１１（ｅ）に示すように、突刺針部１１２の貫通部位の外側に、加締め金具１２０を加締め付けたら、被覆電線１００と端子金具１１０の導通接続が完了する。 In the electric wire and terminal connection structure of Patent Document 1, as shown in FIG. 11 (e), when the caulking metal fitting 120 is caulked outside the penetrating portion of the piercing needle portion 112, the covered electric wire 100 and the terminal metal fitting 110 are connected. Conductive connection is completed.

被覆電線１００の導通接続が完了した端子金具１１０は、この後、不図示のコネクタハウジングの端子収容孔に挿入装着されて、相手端子への嵌合接続が可能になる。 Thereafter, the terminal fitting 110 for which the conductive connection of the covered electric wire 100 has been completed is inserted and mounted in a terminal receiving hole of a connector housing (not shown) so that the fitting connection to the mating terminal becomes possible.

この特許文献１における電線と端子の接続構造の場合、端子金具を接続する被覆電線は、被覆を剥がさずに、端子金具に接続することができる。そのため、被覆電線の被覆を所定長に渡って剥ぎ取った後に、露出した電線導体の上に端子金具の加締め片を加締め付ける従来の圧着式の端子金具を用いる場合と比較すると、電線の接続作業を容易にすることができる。 In the case of the connection structure between the electric wire and the terminal in Patent Document 1, the covered electric wire connecting the terminal fitting can be connected to the terminal fitting without removing the coating. Therefore, compared to the case of using a conventional crimp-type terminal fitting, in which the sheath of the covered wire is stripped over a predetermined length and then the crimped piece of the terminal fitting is crimped on the exposed wire conductor, the wire connection Work can be facilitated.

The electric wire and terminal connection structure according to (1) or (2) above, wherein

上記（１）の構成によれば、複数の端子金具と複数の絶縁被覆と接続した接続構造を得る場合、次の第１の作業と、第２の作業を順に行えば良い。 According to the configuration of (1) above, when obtaining a connection structure in which a plurality of terminal fittings and a plurality of insulating coatings are connected, the following first operation and second operation may be performed in order.

第１の作業は、複数の端子金具が端子収容部に配列済みのコネクタハウジングの電線収容部に、複数の被覆電線を配列する作業である。電線収容部に収容する被覆電線は、被覆の剥ぎ取りをせずに、被覆を付けたまま単純に配列していくだけで良い。 The first operation is an operation of arranging the plurality of covered wires in the wire housing portion of the connector housing in which the plurality of terminal fittings are already arranged in the terminal housing portion. The covered electric wires to be accommodated in the electric wire accommodating portion may be simply arranged with the covering attached, without peeling off the covering.

第２の作業は、被覆電線の配列を済ませたコネクタハウジングの開口部に、ハウジングカバーを取り付ける作業である。 The second operation is an operation of attaching the housing cover to the opening portion of the connector housing in which the covered electric wires are arranged.

第２の作業を行うと、ハウジングカバーの内面に装備されている複数の電線接続針の突刺針部が、一括して、複数の被覆電線の芯線に突き刺さり、それぞれの被覆電線と導通状態になる。また、同時に、複数の電線接続針の端子接触部が、一括して、複数の端子金具の端子嵌合部に重なって、それぞれの端子金具と導通状態になる。 When the second operation is performed, the piercing needle portions of the plurality of electric wire connecting needles provided on the inner surface of the housing cover are collectively pierced into the core wires of the plurality of covered electric wires and become conductive with the respective covered electric wires. . At the same time, the terminal contact portions of the plurality of wire connecting needles collectively overlap the terminal fitting portions of the plurality of terminal fittings, and are brought into conduction with the respective terminal fittings.

従って、第２の作業を行うことで、複数の端子金具と複数の被覆電線とを一括して導通接続することができる。 Therefore, by performing the second operation, the plurality of terminal fittings and the plurality of covered electric wires can be collectively connected to each other.

また、第２の作業が完了すると、コネクタハウジングの開口部がハウジングカバーによって閉じられた状態になり、複数の端子金具はコネクタハウジングに収容されて保護された状態となる。そのため、端子金具と被覆電線との接続部が外部の構造物等と干渉することがなく、安全に取り扱うことができる。 When the second operation is completed, the opening of the connector housing is closed by the housing cover, and the plurality of terminal fittings are housed in the connector housing and protected. Therefore, the connection part of a terminal metal fitting and a covered electric wire does not interfere with an external structure etc., and can be handled safely.

従って、上記（１）の構成によれば、複数の端子金具と複数の絶縁被覆と接続した接続構造を得る場合、第１の作業と第２の作業との２つの作業を順に行えば良く、複数の被覆電線と複数の端子金具との接続作業性を大幅に改善することができる。 Therefore, according to the configuration of (1) above, when obtaining a connection structure in which a plurality of terminal fittings and a plurality of insulating coatings are connected, the two operations of the first operation and the second operation may be performed sequentially. Connection workability between the plurality of covered electric wires and the plurality of terminal fittings can be greatly improved.

上記（２）の構成によれば、電線接続針の突刺針部は、芯線に対して傾斜した状態で突き刺さっており、突刺針部が芯線に対して直交方向に突き刺さる従来の接続構造の場合と比較すると、芯線と突刺針部との接触長が長くなり、電気的な接続性能を向上させることができる。 According to the configuration of (2) above, the piercing needle portion of the electric wire connecting needle is pierced in an inclined state with respect to the core wire, and the piercing needle portion is pierced in a direction orthogonal to the core wire and In comparison, the contact length between the core wire and the puncture needle is increased, and the electrical connection performance can be improved.

上記（３）の構成によれば、構成部品の組立誤差等によって、コネクタハウジング内の端子金具の端子嵌合部と、該端子嵌合部上に重ねられる電線接続針の端子接触部との間の寸法にばらつきが発生する場合でも、端子嵌合部と端子接触部との間に介在するばね部材の圧縮変形が、寸法のばらつきを吸収して、端子嵌合部と端子接触部との間に安定した接触圧を確保することができる。従って、組立誤差の影響で端子金具と電線接続針との電気的な接続性能が低下することがなく、良好な接続性能を維持することができる。 According to the configuration of (3) above, between the terminal fitting portion of the terminal fitting in the connector housing and the terminal contact portion of the wire connecting needle overlaid on the terminal fitting portion due to assembly errors of the component parts, etc. Even if there is a variation in the dimensions of the spring, the compression deformation of the spring member interposed between the terminal fitting portion and the terminal contact portion absorbs the variation in the size, so that there is a gap between the terminal fitting portion and the terminal contact portion. A stable contact pressure can be ensured. Therefore, the electrical connection performance between the terminal fitting and the wire connection needle is not deteriorated due to the influence of the assembly error, and good connection performance can be maintained.

本発明による電線と端子の接続構造によれば、複数の端子金具が端子収容部に配列済みのコネクタハウジングの電線収容部に複数の被覆電線を配列する第１の作業と、第１の作業を済ませたコネクタハウジングの開口部にハウジングカバーを取り付ける第２の作業と、を順に行うだけで、複数の端子金具と複数の被覆電線とを一括して導通接続することができる。また、同時に、第２の作業が完了すると、コネクタハウジングの開口部がハウジングカバーによって閉じられた状態になり、複数の端子金具はコネクタハウジングに収容されて保護された状態となる。そのため、端子金具と被覆電線との接続部が外部の構造物等と干渉することがなく、安全に取り扱うことができる。 According to the connection structure between the electric wire and the terminal according to the present invention, the first operation of arranging the plurality of covered electric wires in the electric wire housing portion of the connector housing in which the plurality of terminal fittings are arranged in the terminal housing portion, and the first operation are performed. The plurality of terminal fittings and the plurality of covered electric wires can be collectively connected by simply performing the second operation of attaching the housing cover to the completed opening of the connector housing. At the same time, when the second operation is completed, the opening of the connector housing is closed by the housing cover, and the plurality of terminal fittings are housed in the connector housing and protected. Therefore, the connection part of a terminal metal fitting and a covered electric wire does not interfere with an external structure etc., and can be handled safely.

従って、本発明による電線と端子の接続構造によれば、複数の端子金具と複数の被覆電線と接続した接続構造を得る場合、次の第１の作業と、第２の作業を順に行えば良く、複数の被覆電線と複数の端子金具との接続作業性を大幅に改善することができる。 Therefore, according to the connection structure of the electric wire and the terminal according to the present invention, when a connection structure in which a plurality of terminal fittings and a plurality of covered electric wires are connected is obtained, the following first operation and second operation may be performed in order. The connection workability between the plurality of covered electric wires and the plurality of terminal fittings can be greatly improved.

Further, by performing the cover attaching operation, as shown in FIGS. 3 and 4, the plurality of covered electric wires 100 and the plurality of terminal fittings 10 are accommodated in the connector housing 20 and protected.

以上に説明した第１実施形態の電線と端子の接続構造では、複数の端子金具１０と複数の絶縁被覆１０３と接続した接続構造を得る場合、次の第１の作業と、第２の作業を順に行えば良い。 In the electric wire and terminal connection structure according to the first embodiment described above, when obtaining a connection structure in which a plurality of terminal fittings 10 and a plurality of insulating coatings 103 are connected, the following first operation and second operation are performed. Just go in order.

第１の作業は、図１に示したように複数の端子金具１０が端子収容部２１に配列済みのコネクタハウジング２０の電線収容部２２に、複数の被覆電線１００を配列する作業である。電線収容部２２に収容する被覆電線１００は、被覆の剥ぎ取りをせずに、被覆を付けたまま単純に配列していくだけで良い。
第２の作業は、図２に示すように、被覆電線１００の配列を済ませたコネクタハウジング２０の開口部２３に、ハウジングカバー３０を取り付ける作業である。 The first operation is an operation of arranging the plurality of covered electric wires 100 in the electric wire accommodating portion 22 of the connector housing 20 in which the plural terminal fittings 10 are already arranged in the terminal accommodating portion 21 as shown in FIG. The covered electric wires 100 accommodated in the electric wire accommodating portion 22 may be simply arranged with the coverings attached, without peeling off the covering.

The core wires 102 are pierced and become conductive with the respective covered wires 100.

また、同時に、複数の電線接続針４０の端子接触部４２が、一括して、複数の端子金具１０の端子嵌合部１１に重なって、それぞれの端子金具１０と導通状態になる。 At the same time, the terminal contact portions 42 of the plurality of wire connecting needles 40 are collectively overlapped with the terminal fitting portions 11 of the plurality of terminal fittings 10 and are brought into conduction with the respective terminal fittings 10.

従って、第２の作業を行うことで、複数の端子金具１０と複数の被覆電線１００とを一括して導通接続することができる。 Therefore, by performing the second work, the plurality of terminal fittings 10 and the plurality of covered electric wires 100 can be collectively connected to each other.

また、第２の作業が完了すると、コネクタハウジング２０の開口部２３がハウジングカバー３０によって閉じられた状態になり、複数の端子金具１０はコネクタハウジング２０に収容されて保護された状態となる。そのため、端子金具１０と被覆電線１００との接続部が外部の構造物等と干渉することがなく、安全に取り扱うことができる。 When the second operation is completed, the opening 23 of the connector housing 20 is closed by the housing cover 30, and the plurality of terminal fittings 10 are housed in the connector housing 20 and protected. Therefore, the connection part between the terminal fitting 10 and the covered electric wire 100 does not interfere with an external structure or the like and can be handled safely.

従って、以上に説明した第１実施形態の電線と端子の接続構造では、複数の端子金具１０と複数の絶縁被覆１０３と接続した接続構造を得る場合、第１の作業と第２の作業との２つの作業を順に行えば良く、複数の被覆電線１００と複数の端子金具１０との接続作業性を大幅に改善することができる。 Therefore, in the connection structure of the electric wire and the terminal of the first embodiment described above, when obtaining the connection structure connected to the plurality of terminal fittings 10 and the plurality of insulating coatings 103, the first work and the second work are performed. Two operations may be performed in order, and the connection workability between the plurality of covered electric wires 100 and the plurality of terminal fittings 10 can be greatly improved.

The contact length with the core wire 102 is L1.

これに対して、図５（ａ）に示すように、突刺針部４１が芯線１０２に対して直交方向に突き刺さる従来の接続構造の場合は、芯線１０２との接触長がＬ２となり、第１実施形態の場合よりも接触長が短い。 On the other hand, as shown in FIG. 5A, in the case of the conventional connection structure in which the piercing needle portion 41 is pierced in a direction orthogonal to the core wire 102, the contact length with the core wire 102 is L2, which is the first implementation. The contact length is shorter than in the case of the form.

この第２実施形態の電線と端子の接続構造は、第１実施形態に示した端子金具１０の一部を改良した端子金具１０Ａが使用される。ハウジングカバー３０には穴３０ａが形成され、コネクタハウジング２０には穴３０ａに係止される突起２０ａが形成されている。 In the connection structure between the electric wire and the terminal of the second embodiment, a terminal fitting 10A obtained by improving a part of the terminal fitting 10 shown in the first embodiment is used. A hole 30 a is formed in the housing cover 30, and a protrusion 20 a that is locked to the hole 30 a is formed in the connector housing 20.

この第２実施形態の端子金具１０Ａは、図６に示すように、端子嵌合部１１の端子接触部４２が重なる位置に、導電材料製のばね部材１５を追加装備したものである。ばね部材１５は、所謂板ばねで、電線接続針４０の端子接触部４２が重なったときに圧縮変形して、所定の接触圧を発生する。 As shown in FIG. 6, the terminal fitting 10 </ b> A according to the second embodiment is additionally provided with a spring member 15 made of a conductive material at a position where the terminal contact portion 42 of the terminal fitting portion 11 overlaps. The spring member 15 is a so-called leaf spring, and is compressed and deformed when the terminal contact portion 42 of the wire connecting needle 40 overlaps to generate a predetermined contact pressure.

図１０（ａ）は、ばね部材１５が圧縮変形する前の無負荷時の高さ寸法ｈ１を示し、図１０（ｂ）はばね部材１５が端子接触部４２による押圧力で圧縮変形した時の高さ寸法ｈ２を示している。 10A shows the height dimension h1 when no load is applied before the spring member 15 is compressed and deformed, and FIG. 10B shows the state when the spring member 15 is compressed and deformed by the pressing force of the terminal contact portion 42.

Therefore, the description is omitted.

この第２実施形態の電線と端子の接続構造の場合も、複数の端子金具１０Ａと複数の絶縁被覆１０３と接続した接続構造を得るには、前述の第１の作業と、第２の作業を順に行えば良い。 Also in the case of the electric wire and terminal connection structure of the second embodiment, in order to obtain a connection structure in which a plurality of terminal fittings 10A and a plurality of insulating coatings 103 are connected, the first operation and the second operation described above are performed. Just go in order.

この第２実施形態の電線と端子の接続構造の場合は、第１実施形態の場合の作用・効果に加えて、次の作用・効果を得ることができる。 In the case of the connection structure between the electric wire and the terminal according to the second embodiment, the following actions / effects can be obtained in addition to the actions / effects of the first embodiment.

即ち、第２実施形態の電線と端子の接続構造の場合は、構成部品の組立誤差等によって、コネクタハウジング２０内の端子金具１０Ａの端子嵌合部１１と、該端子嵌合部１１上に重ねられる電線接続針４０の端子接触部４２との間の寸法にばらつきが発生する場合でも、端子嵌合部１１と端子接触部４２との間に介在するばね部材１５の圧縮変形が、寸法のばらつきを吸収して、端子嵌合部１１と端子接触部４２との間に安定した接触圧を確保することができる。従って、組立誤差の影響で端子金具１０Ａと電線接続針４０との電気的な接続性能が低下することがなく、良好な接続性能を維持することができる。 That is, in the case of the electric wire and terminal connection structure of the second embodiment, the terminal fitting portion 11 of the terminal fitting 10A in the connector housing 20 and the terminal fitting portion 11 are overlapped due to an assembly error of components. Even if the dimension between the terminal contact portion 42 of the electric wire connecting needle 40 to be generated varies, the compression deformation of the spring member 15 interposed between the terminal fitting portion 11 and the terminal contact portion 42 causes the variation in dimension. Thus, a stable contact pressure can be ensured between the terminal fitting portion 11 and the terminal contact portion 42. Therefore, the electrical connection performance between the terminal fitting 10A and the wire connecting needle 40 does not deteriorate due to the influence of assembly errors, and good connection performance can be maintained.

被覆電線１００と端子金具１０Ａとの接続は、ハウジングカバー３０に形成された穴３０ａに、コネクタハウジング２０に形成された突起２０ａが係止されることにより維持されると共に、電線接続針４０を被覆電線１００に挿入した時の圧力により発生する金属間結合（凝着）により保持される。 The connection between the covered electric wire 100 and the terminal fitting 10A is maintained by locking the protrusion 20a formed in the connector housing 20 in the hole 30a formed in the housing cover 30, and the electric wire connecting needle 40 is covered. It is held by a metal-to-metal bond (adhesion) generated by pressure when inserted into the electric wire 100.

In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

例えば、端子金具は、芯線１０２が電線接続針４０を介して端子嵌合部１１に導通接続されるため、端子嵌合部１１に連設されている電線載置部１２を省略する構造としてもよい。 For example, since the core wire 102 is conductively connected to the terminal fitting portion 11 via the electric wire connecting needle 40, the terminal fitting may have a structure in which the electric wire placement portion 12 connected to the terminal fitting portion 11 is omitted. Good.
