このようなカバー９は、ハウジング５にヒンジ１７を介して開閉可能にハウジング５と一体に設けられている。 Such a cover 9 is provided integrally with the housing 5 so as to be openable and closable on the housing 5 via a hinge 17.

このようにカバー９をハウジング５にヒンジ１７を介して一体に設けることにより、ハウジング５とカバー９とを別体で取り扱うことがなく、部品点数を低減することができる。 By integrally providing the cover 9 to the housing 5 via the hinge 17 in this way, the housing 5 and the cover 9 are not handled separately, and the number of parts can be reduced.

ここで、端子７の端子接続部３５には、底壁から切り起こされ、所定の付勢力を有するガタ詰めバネ１１が設けられている。 Here, the terminal connection portion 35 of the terminal 7 is provided with a backlash-filling spring 11 that is cut up from the bottom wall and has a predetermined urging force.

このガタ詰めバネ１１は、カバー９がハウジング５に組付けられた状態で、カバー９に設けられたガタ詰めリブ１３に当接される。 The backlash filling spring 11 comes into contact with the backlash filling rib 13 provided on the cover 9 in a state where the cover 9 is assembled to the housing 5.

ガタ詰めリブ１３は、カバー９のハウジング５に対する閉塞面から外方に向けて突設され、カバー９をハウジング５に組付けた状態で、挿入開口２９から端子収容室３内に挿入される。 The backlash filling rib 13 is projected outward from the closing surface of the cover 9 with respect to the housing 5, and is inserted into the terminal accommodating chamber 3 through the insertion opening 29 with the cover 9 assembled to the housing 5.

このガタ詰めリブ１３は、端子収容室３内に挿入された状態で、端子７のガタ詰めバネ１１と当接し、端子７を端子収容室３の挿入方向に押圧する。 The backlash filling rib 13 comes into contact with the backlash filling spring 11 of the terminal 7 in a state of being inserted into the terminal accommodating chamber 3, and presses the terminal 7 in the insertion direction of the terminal accommodating chamber 3.

このようなガタ詰めリブ１３による端子７の押圧により、端子７の端子接続部３５の端面が接続開口３１が設けられた壁部に当接され、端子収容室３内における端子７の挿抜方向のガタ詰めが行われる。 By pressing the terminal 7 with the backlash-filling rib 13, the end surface of the terminal connection portion 35 of the terminal 7 is brought into contact with the wall portion provided with the connection opening 31, and the terminal 7 is inserted and removed in the terminal accommodation chamber 3. The backlash is packed.

このため、ハウジング５にカバー９を組付けた状態では、ガタ詰めバネ１１とガタ詰めリブ１３との当接により、端子収容室３内で端子７が挿抜方向にガタつくことがなく、車両の走行などの振動によって、異音が発生することを防止することができる。 Therefore, in the state where the cover 9 is assembled to the housing 5, the terminal 7 does not rattle in the terminal accommodating chamber 3 due to the contact between the backlash-filling spring 11 and the backlash-filling rib 13, and the vehicle does not rattle in the insertion / removal direction. It is possible to prevent abnormal noise from being generated due to vibration such as running.

ここで、端子収容室３に端子７の端子接続部３５を挿入したときに、係止部１５の係止突起４７が端子接続部３５の係合孔４９に挿入されず、端子収容室３に対して端子７が中途挿入状態となってしまうことがある。 Here, when the terminal connecting portion 35 of the terminal 7 is inserted into the terminal accommodating chamber 3, the locking projection 47 of the locking portion 15 is not inserted into the engaging hole 49 of the terminal connecting portion 35, and the terminal accommodating chamber 3 is inserted. On the other hand, the terminal 7 may be inserted halfway.

このような端子７の中途挿入状態であっても、カバー９をハウジング５に組付けることにより、ガタ詰めバネ１１とガタ詰めリブ１３とが当接し、端子７が端子収容室３への挿入方向に押圧され、端子７が端子収容室３の正規位置に配置される。 Even in such a state where the terminal 7 is inserted halfway, by assembling the cover 9 to the housing 5, the backlash filling spring 11 and the backlash filling rib 13 come into contact with each other, and the terminal 7 is inserted into the terminal accommodating chamber 3. , And the terminal 7 is arranged at the regular position of the terminal accommodating chamber 3.

このガタ詰めリブ１３の押圧による端子７の移動により、係止部１５の係止突起４７を端子接続部３５の係合孔４９に挿入させることができ、端子収容室３に対する端子７の中途挿入状態を防止することができる。 By moving the terminal 7 by pressing the backlash filling rib 13, the locking projection 47 of the locking portion 15 can be inserted into the engaging hole 49 of the terminal connecting portion 35, and the terminal 7 is inserted halfway into the terminal accommodating chamber 3. The condition can be prevented.

このようなコネクタ１では、カバー９に、カバー９がハウジング５に組付けられた状態でガタ詰めバネ１１と当接して端子７を端子収容室３の挿入方向に押圧し端子収容室３に対する端子７の挿抜方向のガタを詰めるガタ詰めリブ１３が設けられている。 In such a connector 1, the cover 9 is in contact with the backlash spring 11 in a state where the cover 9 is assembled to the housing 5, and the terminal 7 is pressed in the insertion direction of the terminal accommodating chamber 3 to press the terminal 7 with respect to the terminal accommodating chamber 3. A backlash filling rib 13 for filling the backlash in the insertion / removal direction of 7 is provided.

このため、カバー９がハウジング５に組付けられた状態では、端子収容室３内において、端子７が挿抜方向にガタつくことがなく、車両の走行などの振動によって、端子７のガタつきに起因する異音の発生を防止することができる。 Therefore, when the cover 9 is assembled to the housing 5, the terminal 7 does not rattle in the insertion / removal direction in the terminal accommodating chamber 3, and the terminal 7 rattles due to vibration such as running of the vehicle. It is possible to prevent the generation of abnormal noise.

従って、このようなコネクタ１では、端子収容室３内における端子７のガタつきを防止し、異音の発生を防止することができる。 Therefore, such a connector 1 can prevent rattling of the terminal 7 in the terminal accommodating chamber 3 and prevent generation of abnormal noise.

また、端子収容室３には、端子収容室３に対して端子７が正規に配置された状態で端子７に係止される係止部１５が設けられているので、端子収容室３から端子７が離脱することをさらに防止することができる。 Further, since the terminal accommodating chamber 3 is provided with a locking portion 15 that is locked to the terminal 7 in a state where the terminal 7 is normally arranged with respect to the terminal accommodating chamber 3, the terminal is provided from the terminal accommodating chamber 3 to the terminal. It is possible to further prevent the 7 from coming off.

加えて、端子収容室３に対して端子７が正規に配置されていない状態であっても、ハウジング５にカバー９を組付けることにより、ガタ詰めバネ１１とガタ詰めリブ１３とが当接し、端子７を端子収容室３の正規位置に配置させることができ、端子７の中途挿入を防止することができる。 In addition, even when the terminal 7 is not properly arranged with respect to the terminal accommodating chamber 3, by assembling the cover 9 to the housing 5, the backlash filling spring 11 and the backlash filling rib 13 come into contact with each other. The terminal 7 can be arranged at a regular position in the terminal accommodating chamber 3, and the terminal 7 can be prevented from being inserted in the middle.

さらに、カバー９は、ハウジング５にヒンジ１７を介して一体に設けられているので、ハウジング５とカバー９とを一体に取り扱うことができ、部品点数を低減することができる。 Further, since the cover 9 is integrally provided on the housing 5 via the hinge 17, the housing 5 and the cover 9 can be handled integrally, and the number of parts can be reduced.

なお、本発明の実施の形態に係るコネクタでは、係止部が端子収容室に撓み可能に設けられた係止ランスとなっているが、これに限らず、例えば、係止部が端子収容室に挿入されるスペーサなどであってもよく、端子収容室の正規位置で端子を係止できるものであれば、係止部はどのようなものであってもよい。 In the connector according to the embodiment of the present invention, the locking portion is a locking lance provided in the terminal accommodating chamber so as to be flexible, but the present invention is not limited to this, and for example, the locking portion is the terminal accommodating chamber. It may be a spacer inserted into the terminal, and any locking portion may be used as long as the terminal can be locked at a regular position in the terminal accommodating chamber.
