The 210 core wire (conductor) may be damaged by excessive bending stress.

特に、電線210の芯線が、曲げに弱いアルミニウム製又はアルミニウム合金製の場合には、電線係止装置100による屈曲によって芯線が受けるダメージが大きく、最悪の場合には、電線係止装置100による屈曲によって芯線切れが発生するおそれがあった。   In particular, when the core wire of the electric wire 210 is made of aluminum or aluminum alloy which is vulnerable to bending, the core wire is greatly damaged by the bending by the electric wire locking device 100. In the worst case, the bending by the electric wire locking device 100 is performed. There was a possibility that the core wire may be broken.

The above-described object of the present invention is achieved by the following configuration.

(2) 前記係止装置カバーを、前記係止装置本体の上面を開閉可能に、前記係止装置本体に結合する薄肉ヒンジ部を備えたことを特徴とする上記(1)に記載の電線係止装置。   (2) The wire device according to (1), wherein the locking device cover includes a thin hinge portion that is coupled to the locking device body so that an upper surface of the locking device body can be opened and closed. Stop device.

(3) 前記係止装置本体に装備されて、前記コネクタハウジングに装備された係止装置連結部との係合により前記係止装置本体を前記コネクタハウジングに結合するハウジング係合部を備えたことを特徴とする上記(1)又は(2)に記載の電線係止装置。   (3) A housing engaging portion that is provided in the locking device main body and couples the locking device main body to the connector housing by engaging with a locking device connecting portion provided in the connector housing. The wire locking device according to the above (1) or (2), characterized in that:

(4) 前記電線は、アルミ電線又はアルミ合金電線であることを特徴とする上記(1)〜(3)のいずれかに記載の電線係止装置。   (4) The electric wire locking device according to any one of (1) to (3), wherein the electric wire is an aluminum electric wire or an aluminum alloy electric wire.

上記(1)の構成によれば、コネクタハウジングの一端に組み付けられた係止装置本体には、コネクタハウジングから導出した電線を、前記係止装置本体の上方から、電線導入溝及び電線ガイド溝及び電線導出溝に順に挿通させることで、簡単に電線を組み付けることができる。また、電線を組付け後に、係止装置本体の上に係止装置カバーを組み付けると、係止装置本体に収容された電線の上が係止装置カバーで覆われて、係止装置本体に収容された電線が保護される。   According to the configuration of (1) above, the locking device main body assembled to one end of the connector housing is connected with the electric wire led out from the connector housing from above the locking device main body, the wire introduction groove, the wire guide groove, An electric wire can be easily assembled by inserting it through the electric wire outlet groove in order. Also, when the locking device cover is assembled on the locking device main body after assembling the electric wire, the electric wire accommodated in the locking device main body is covered with the locking device cover and accommodated in the locking device main body. The protected electric wire is protected.

即ち、コネクタハウジングから導出した電線は、簡単に係止装置本体に挿通することができ、また、係止装置カバーにより保護される。   That is, the electric wire led out from the connector housing can be easily inserted into the locking device main body and is protected by the locking device cover.

また、係止装置本体に組み付けられた電線は、螺旋状に係止装置本体内の支柱部を周回して、電線導出溝から外部に導出されている。そのため、電線係止装置から導出した電線に張力や振動がかかると、電線は係止装置本体内の支柱部を締め付けて、電線に作用する張力を支柱部が受ける。   Moreover, the electric wire assembled | attached to the latching device main body goes around the support | pillar part in a latching device main body helically, and is derived | led-out outside from the electric wire extraction groove | channel. Therefore, when tension or vibration is applied to the electric wire led out from the electric wire locking device, the electric wire tightens the column portion in the locking device main body, and the column portion receives the tension acting on the electric wire.

即ち、電線が巻き付く係止装置本体内の支柱部が、張力がかかった電線を係止し、電線に作用している張力を受けて、電線に作用する張力や振動が端子金具や端子金具を係止しているコネクタハウジング内の端子係止部に作用することを防止するストレインリリーフ構造を実現する。   That is, the struts in the locking device main body around which the electric wire wraps locks the tensioned electric wire, receives the tension acting on the electric wire, and the tension and vibration acting on the electric wire are affected by the terminal fitting and terminal fitting. A strain relief structure that prevents the terminal locking portion in the connector housing that locks the terminal from being acted on is realized.

そして、係止装置本体内の支柱部への巻き付きによる電線の係止は、電線を緩やかに湾曲させた状態でしっかりと固定することができ、電線に急角度の折曲が形成されないため、電線の芯線に過大な曲げ応力が作用することがなく、電線に負担をかけないストレインリリーフ構造を実現することができる。   And the locking of the electric wire by wrapping around the support column in the locking device main body can be firmly fixed in a state where the electric wire is gently curved, and the electric wire is not formed with a sharp bend. Therefore, an excessive bending stress does not act on the core wire, and a strain relief structure that does not place a burden on the electric wire can be realized.

上記(2)の構成によれば、電線係止装置を構成する係止装置本体と係止装置カバーとが薄肉ヒンジ部により繋がっているため、電線係止装置を単一部品とすることができ、電線係止装置の部品管理を容易にすることができる。   According to the configuration of (2) above, since the locking device main body and the locking device cover constituting the wire locking device are connected by the thin hinge portion, the wire locking device can be a single component. The parts management of the wire locking device can be facilitated.

上記(3)の構成によれば、係止装置本体は、当該係止装置本体に装備されているハウジング係合部をコネクタハウジングに装備されている係止装置連結部に係合させることでコネクタハウジングに結合することができ、係止装置本体のコネクタハウジングへの取り付けを容易にすることができる。   According to the configuration of (3) above, the locking device main body engages the locking device connecting portion provided in the connector housing by engaging the housing engaging portion provided in the locking device main body with the connector. It can couple | bond with a housing and can make attachment to the connector housing of a locking device main body easy.

上記(4)の構成によれば、電線係止装置が係止する電線が、曲げに弱いアルミ電線又はアルミ合金電線でも、電線係止装置内での電線の係止は電線を緩やかな湾曲状態に支柱部に巻き付けることで行っており、電線に急激な折曲部を形成しないため、電線の芯線切れを防止することができる。   According to the configuration of the above (4), even if the electric wire locked by the electric wire locking device is an aluminum wire or an aluminum alloy wire that is weak against bending, the electric wire locking in the electric wire locking device is a gently curved state. Since the wire is wound around the support and does not form a sharp bent portion in the electric wire, it is possible to prevent the core wire from being cut.

即ち、コネクタハウジングから導出する電線がアルミ電線又はアルミ合金電線の場合でも、安全に電線を係止するストレインリリーフ構造を実現することができる。   That is, even when the electric wire led out from the connector housing is an aluminum electric wire or an aluminum alloy electric wire, a strain relief structure that can safely lock the electric wire can be realized.

本発明による電線係止装置によれば、電線を無理に屈曲させずに、緩やかに湾曲させた状態でしっかりと固定することができ、電線に負担をかけないストレインリリーフ構造を実現することができる。   According to the electric wire locking device of the present invention, it is possible to realize a strain relief structure that can be firmly fixed in a gently curved state without forcibly bending the electric wire and that does not place a burden on the electric wire. .

即ち、電線6が巻き付く係止装置本体41内の支柱部413が、張力がかかった電線6を係止し、電線6に作用している張力を受けて、電線6に作用する張力が端子金具や端子金具を係止しているコネクタハウジング5内の端子係止部に作用することを防止するストレインリリーフ構造を実現する。   That is, the support column 413 in the locking device main body 41 around which the electric wire 6 wraps locks the electric wire 6 under tension, receives the tension acting on the electric wire 6, and the tension acting on the electric wire 6 becomes the terminal. A strain relief structure that prevents the terminal locking portion in the connector housing 5 locking the metal fitting or the terminal metal fitting from being applied is realized.

そして、係止装置本体41内の支柱部413への巻き付きによる電線6の係止は、電線6を緩やかに湾曲させた状態でしっかりと固定することができ、電線6に急角度の折曲が形成されないため、電線6の芯線に過大な曲げ応力が作用することがなく、電線6に負担をかけないストレインリリーフ構造を実現することができる。   And the lock | rock of the electric wire 6 by the winding to the support | pillar part 413 in the latching | locking apparatus main body 41 can be fixed firmly in the state which bent the electric wire 6 gently, and an acute angle bending is carried out to the electric wire 6. Since it is not formed, an excessive bending stress does not act on the core wire of the electric wire 6, and a strain relief structure that does not place a burden on the electric wire 6 can be realized.

また、一実施形態の電線係止装置4の場合、電線係止装置4を構成する係止装置本体41と係止装置カバー42とが薄肉ヒンジ部43により繋がっているため、電線係止装置4を単一部品とすることができ、電線係止装置4の部品管理を容易にすることができる。   In the case of the wire locking device 4 according to the embodiment, the locking device main body 41 and the locking device cover 42 constituting the wire locking device 4 are connected by the thin hinge 43, and therefore the wire locking device 4. Can be made into a single component, and component management of the wire locking device 4 can be facilitated.

また、一実施形態の電線係止装置4の場合、係止装置本体41は、当該係止装置本体41に装備されているハウジング係合部411をコネクタハウジング5に装備されている係止装置連結部51に係合させることでコネクタハウジング5に結合することができ、係止装置本体41のコネクタハウジング5への取り付けを容易にすることができる。   In the case of the wire locking device 4 according to the embodiment, the locking device main body 41 includes a housing engaging portion 411 provided in the locking device main body 41 and a locking device connection provided in the connector housing 5. By engaging with the portion 51, it can be coupled to the connector housing 5, and attachment of the locking device main body 41 to the connector housing 5 can be facilitated.

更に、一実施形態の電線係止装置4の場合、電線係止装置4が係止する電線6が、曲げに弱いアルミ電線でも、電線係止装置4内での電線6の係止は電線6を緩やかな湾曲状態に支柱部413に巻き付けることで行っており、電線6に急激な折曲部を形成しないため、電線6の芯線切れを防止することができる。   Furthermore, in the case of the wire locking device 4 according to the embodiment, even if the wire 6 locked by the wire locking device 4 is an aluminum wire that is weak against bending, the locking of the wire 6 in the wire locking device 4 is the wire 6. Is wound around the support column 413 in a gently curved state, and since a sharp bent portion is not formed in the electric wire 6, the core wire of the electric wire 6 can be prevented from being cut.

即ち、コネクタハウジング5から導出する電線6がアルミ電線の場合でも、安全に電線6を係止するストレインリリーフ構造を実現することができる。   That is, even when the electric wire 6 led out from the connector housing 5 is an aluminum electric wire, it is possible to realize a strain relief structure for safely locking the electric wire 6.

本実施形態の電線係止装置4が係止する電線6は、アルミ電線に限るものではなく、アルミ合金電線の場合でも、芯線切れの防止に有用である。又、芯線が一般的な銅線、又は銅合金の場合も、芯線切れの防止に有用である。   The electric wire 6 which the electric wire locking device 4 of this embodiment latches is not restricted to an aluminum electric wire, and even in the case of an aluminum alloy electric wire, it is useful for prevention of a core wire breakage. Further, when the core wire is a general copper wire or copper alloy, it is useful for preventing the core wire from being cut.
