　下記の特許文献１及び特許文献２には、コネクタにおける端子金具のガタ付きを防止する技術が開示されている。 In a connector used for an in-vehicle wire harness, it is important to prevent the terminal fitting from being loosened in order to suppress a decrease in electrical connection performance due to the looseness of the terminal fitting in a vibration environment.
The following Patent Document 1 and Patent Document 2 disclose a technique for preventing the backlash of the terminal fitting in the connector.
　下記特許文献１に開示されたガタ付き防止技術では、図１８に示すように、雌端子金具１１０を収容するハウジング１００が、雌端子金具１１０を収容保持した樹脂製の端子収容部材１２０と、該端子収容部材１２０を挿抜可能な樹脂製のケース１３０と、で構成されている。 In the rattling prevention technique disclosed in Patent Document 1 below, as shown in FIG. 18, the housing 100 that houses the female terminal fitting 110 includes a resin terminal housing member 120 that houses and holds the female terminal fitting 110, and the And a resin case 130 into which the terminal accommodating member 120 can be inserted and removed.
　また、端子収容部材１２０は、雌端子金具１１０が挿入される端子収容孔１２１が画成されている上壁１２２に、端子係止ランス１２３が設けられている。 Further, the terminal receiving member 120 is provided with a terminal locking lance 123 on the upper wall 122 in which the terminal receiving hole 121 into which the female terminal fitting 110 is inserted is defined.
　端子係止ランス１２３は、端子収容孔１２１に対する雌端子金具１１０の挿抜方向（図１８中では、矢印Ｘ１方向）と直交する方向（図１８中では、矢印Ｙ１方向）に撓み変形可能な弾性片１２３ａと、この弾性片１２３ａから端子収容孔１２１の内方に突出した端子係止突起１２３ｂと、端子係止突起１２３ｂから端子収容孔１２１の外方に突出したガタ止め用突起１２３ｃと、を備えている。 The terminal locking lance 123 is an elastic piece that can be bent and deformed in a direction (arrow Y1 direction in FIG. 18) orthogonal to the insertion / extraction direction of the female terminal fitting 110 with respect to the terminal receiving hole 121 (arrow X1 direction in FIG. 18). 123a, a terminal locking protrusion 123b protruding inward of the terminal receiving hole 121 from the elastic piece 123a, and a ratchet protrusion 123c protruding outward of the terminal receiving hole 121 from the terminal locking protrusion 123b. ing.
　特許文献１における端子係止ランス１２３は、端子係止突起１２３ｂが雌端子金具１１０の段差部１１１に係合されることで、雌端子金具１１０が抜け止めされる。また、端子係止ランス１２３は、端子収容部材１２０がケース１３０に挿入された際に、ガタ止め用突起１２３ｃがケース１３０の上部壁１３１により押圧付勢されて、雌端子金具１１０側に弾性変形した状態になる。そして、この時にガタ止め用突起１２３ｃから上部壁１３１に作用する弾性反力により、端子収容部材１２０がガタ止めされる。 In the terminal locking lance 123 in Patent Document 1, the terminal locking projection 123b is engaged with the step portion 111 of the female terminal fitting 110, so that the female terminal fitting 110 is prevented from coming off. Further, when the terminal accommodating member 120 is inserted into the case 130, the terminal locking lance 123 is elastically deformed toward the female terminal fitting 110 side by the backlash projection 123c being pressed and urged by the upper wall 131 of the case 130. It will be in the state. At this time, the terminal accommodating member 120 is rattled by the elastic reaction force acting on the upper wall 131 from the ratchet projection 123c.
　下記特許文献２に開示されたガタ付き防止技術は、ハウジング内に、雌端子金具の外面に対向する可撓性バンド部と、該可撓性バンド部に突設されて前記雌端子金具の外面に前記雌端子金具の挿抜方向と直交する方向の押圧力を付与する位置規制用突起と、を設けたものである。即ち、特許文献２では、ハウジング内の雌端子金具に、直接、挿抜方向と直交する方向の押圧力が付与されることで、雌端子金具のガタ付きが防止される。 The backlash prevention technology disclosed in Patent Document 2 below includes a flexible band portion facing the outer surface of the female terminal fitting in the housing, and an outer surface of the female terminal fitting protruding from the flexible band portion. And a position regulating protrusion for applying a pressing force in a direction orthogonal to the insertion / extraction direction of the female terminal fitting. That is, in Patent Document 2, the female terminal fitting in the housing is directly applied with a pressing force in a direction orthogonal to the insertion / extraction direction, thereby preventing the female terminal fitting from being loose.

(1) A first housing having a female terminal accommodating portion for holding a female terminal fitting, and a male terminal fitting having a tongue-shaped terminal tip fitted to the female terminal fitting, A second housing to be fitted and connected,
The female terminal accommodating portion is connected to the female terminal accommodating hole for accommodating the female terminal fitting, the female terminal accommodating hole is opened at the distal end surface of the female terminal accommodating portion, and the tongue-shaped terminal distal end portion is A male terminal insertion hole that can be inserted, a restriction piece insertion hole that communicates with one side of the female terminal accommodation hole and extends in parallel with the female terminal accommodation hole and opens at a distal end surface of the female terminal accommodation portion, With
The second housing includes a cylindrical portion in which the female terminal accommodating portion is fitted, and the terminal tip portion is fitted in the female terminal fitting in the female terminal accommodating portion fitted in the cylindrical portion. The male terminal accommodating portion that holds the male terminal fitting, and the cylindrical shape that faces the distal end surface of the female terminal accommodating portion so as to be inserted into the restriction piece insertion hole of the female terminal accommodating portion fitted into the cylindrical portion. A backlash regulating piece projecting on the inner bottom surface of the part,
In a state in which the first housing and the second housing are fitted and connected, the backlash restricting piece presses and urges one surface of the female terminal fitting in the female terminal housing portion, and the female terminal fitting has a backlash. Connector that suppresses
　（２）　上記（１）に記載のコネクタであって、
　前記雌端子収容部は、前記雌端子金具の挿入途中では前記雌端子金具との干渉によって前記雌端子収容孔の外方側に弾性変位し、前記雌端子金具の挿入が完了した時には弾性復元力で前記雌端子収容孔内に突出した状態に戻って前記雌端子金具を抜け止めする端子係止ランスを備えると共に、前記規制片挿入孔内が前記端子係止ランスの弾性変位を許容する空間となるように前記端子係止ランスが配置されているコネクタ。 (2) The connector according to (1) above,
The female terminal receiving portion elastically displaces outward of the female terminal receiving hole due to interference with the female terminal fitting during the insertion of the female terminal fitting, and an elastic restoring force is obtained when the insertion of the female terminal fitting is completed. And a terminal locking lance that returns to the state protruding into the female terminal receiving hole and prevents the female terminal fitting from coming off, and the inside of the restricting piece insertion hole allows space for elastic displacement of the terminal locking lance. A connector in which the terminal locking lance is arranged to be.
　（３）　上記（１）又は（２）に記載のコネクタであって、
　前記ガタ規制片が、前記端子先端部の先端よりも先方に突出されているコネクタ。 (3) The connector according to (1) or (2) above,
The connector in which the play restricting piece protrudes further forward than the tip of the terminal tip.
　上記（１）の構成によれば、第１ハウジングと第２ハウジングとが嵌合接続されると、それぞれのハウジングに収容されている雌端子金具と雄端子金具とが嵌合する一方、第２ハウジングに設けられているガタ規制片が第１ハウジングの規制片挿入孔に進入する。そして、第１ハウジングの規制片挿入孔に進入したガタ規制片は、第１ハウジング内の雌端子金具の一面を押圧付勢して、雌端子金具のガタ付きを抑止する。 According to the configuration of the above (1), when the first housing and the second housing are fitted and connected, the female terminal fitting and the male terminal fitting housed in each housing are fitted, while the second housing The backlash restricting piece provided in the housing enters the restricting piece insertion hole of the first housing. Then, the backlash restricting piece that has entered the restricting piece insertion hole of the first housing presses and urges one surface of the female terminal fitting in the first housing to suppress the play of the female terminal fitting.
　即ち、上記（１）の構成によれば、雌端子金具のガタ付きの抑止は、第２ハウジングの筒状部の内底面に突設されたガタ規制片によって行われ、第２ハウジング自体は単一部品で済むため、構成部品の増加を招くことがない。 That is, according to the configuration of (1) above, the rattling of the female terminal fitting is performed by the backlash restricting piece projecting on the inner bottom surface of the cylindrical portion of the second housing, and the second housing itself is a single unit. Since only one part is required, the number of components does not increase.
　また、第２ハウジングに設けられるガタ規制片は、当該第２ハウジングへの雄端子金具の挿抜には何ら関与せず、また、第１ハウジングへの雌端子金具の挿抜にも関与しない。即ち、ガタ規制片は、それぞれのハウジングにおける端子金具の挿抜時には、いずれの端子金具にも接触しないため、端子金具の挿抜に大きな操作力が必要となることもない。従って、端子金具の挿抜性の悪化といった問題を招くこともない。 Further, the backlash restricting piece provided in the second housing does not participate in the insertion / extraction of the male terminal fitting to / from the second housing, and does not participate in the insertion / extraction of the female terminal fitting in the first housing. In other words, the backlash restricting piece does not contact any of the terminal fittings when inserting or removing the terminal fittings in the respective housings, so that a large operating force is not required for inserting or removing the terminal fittings. Therefore, the problem of deterioration of the insertion / extraction of the terminal fitting is not caused.
　従って、上記（１）の構成によれば、構成部品の増加や端子金具の挿抜性の悪化といった問題を招くことなく、振動環境下における端子金具のガタ付きを抑制して、安定した電気的接続性能を維持することができる。 Therefore, according to the configuration of (1) above, stable electrical connection can be achieved by suppressing the backlash of the terminal fitting in a vibration environment without causing problems such as an increase in the number of components and deterioration of the insertion / extraction of the terminal fitting. The performance can be maintained.
　上記（２）の構成によれば、第１ハウジングの雌端子収容孔に挿入された雌端子金具が嵌合途中で停止した半嵌合状態の場合、端子係止ランスが規制片挿入孔内に撓んで突出している。そのため、半嵌合状態の第１ハウジングと第２ハウジングとを嵌合接続しようとすると、規制片挿入孔内に進入する第２ハウジングのガタ規制片が、規制片挿入孔内に撓んで突出している端子係止ランスと衝突し、ハウジング相互の嵌合を完了させることができない。
　即ち、ガタ規制片が雌端子金具の半嵌合状態を検知する半嵌合検知機構として機能し、雌端子金具の半嵌合状態の見落としを防止することができる。 According to the configuration of (2) above, when the female terminal fitting inserted into the female terminal receiving hole of the first housing is in a half-fitted state where it is stopped in the middle of fitting, the terminal locking lance is in the restriction piece insertion hole. It bends and protrudes. For this reason, when trying to fit and connect the first housing and the second housing in the semi-fitted state, the backlash regulating piece of the second housing entering the regulating piece insertion hole is bent and protrudes into the regulating piece insertion hole. It collides with the terminal locking lance which is present, and the mutual fitting of the housing cannot be completed.
That is, the backlash regulating piece functions as a half-fitting detection mechanism that detects the half-fitted state of the female terminal fitting, and can prevent oversight of the half-fitted state of the female terminal fitting.
　上記（３）の構成によれば、ガタ規制片が端子先端部の先端よりも先方に突出しているため、第２ハウジングの保管時や運搬時において、外部機材等が筒状部内に進入しても、雄端子金具の舌片状の端子先端部と外部機材等との接触が、ガタ規制片により防がれる。即ち、ガタ規制片が雄端子金具の端子先端部を保護し、前記端子先端部の変形や破損を防止することができる。 According to the configuration of (3) above, since the backlash restricting piece protrudes further forward than the tip of the terminal tip, external equipment or the like enters the cylindrical part during storage or transportation of the second housing. However, the contact between the tongue-shaped terminal tip of the male terminal fitting and the external equipment is prevented by the backlash regulating piece. That is, the backlash regulating piece protects the terminal tip of the male terminal fitting, and can prevent deformation and breakage of the terminal tip.

　ガタ規制片４３は、図１３に示すように、雌端子収容部２１の先端面と対向する筒状部４１の内底面４１ｂに突設されている。ガタ規制片４３は、筒状部４１に嵌合した雌端子収容部２１の規制片挿入孔２１４に挿通するように、内底面４１ｂから雌端子収容部２１の嵌合方向に沿って突出している。
　本実施形態の場合、このガタ規制片４３は、図１３に示すように、端子先端部３１の先端よりも先方に突出している。 As shown in FIG. 13, the backlash regulating piece 43 protrudes from the inner bottom surface 41 b of the cylindrical portion 41 that faces the front end surface of the female terminal accommodating portion 21. The play restricting piece 43 protrudes from the inner bottom surface 41b along the fitting direction of the female terminal accommodating portion 21 so as to be inserted into the restricting piece insertion hole 214 of the female terminal accommodating portion 21 fitted to the cylindrical portion 41. .
In the case of the present embodiment, the backlash regulating piece 43 protrudes further forward than the tip of the terminal tip 31 as shown in FIG.
　本実施形態のコネクタ１では、図１及び図２に示したように第１ハウジング２０と第２ハウジング４０とが嵌合接続された状態では、図１４にも示すように、第２ハウジング４０のガタ規制片４３が第１ハウジング２０の規制片挿入孔２１４に進入し、雌端子収容部２１内の雌端子金具１０の一面（図１４では、下面）を押圧付勢して、雌端子金具１０のガタ付きを抑止する。 In the connector 1 of the present embodiment, in the state where the first housing 20 and the second housing 40 are fitted and connected as shown in FIGS. 1 and 2, as shown in FIG. The play restricting piece 43 enters the restricting piece insertion hole 214 of the first housing 20, and presses and urges one surface (the lower surface in FIG. 14) of the female terminal fitting 10 in the female terminal accommodating portion 21. Suppress backlash.
　以上に説明した本実施形態のコネクタ１の場合、第１ハウジング２０と第２ハウジング４０とが嵌合接続されると、第１及び第２ハウジング２０，４０にそれぞれ収容されている雌端子金具１０と雄端子金具３０とが図１４に示すように、嵌合される一方、第２ハウジング４０に設けられているガタ規制片４３が第１ハウジング２０の規制片挿入孔２１４に進入する。そして、第１ハウジング２０の規制片挿入孔２１４に進入したガタ規制片４３は、第１ハウジング２０内の雌端子金具１０の一面（図１４では、下面）を押圧付勢して、雌端子金具１０のガタ付きを抑止する。 In the case of the connector 1 of the present embodiment described above, when the first housing 20 and the second housing 40 are fitted and connected, the female terminal fitting 10 accommodated in the first and second housings 20 and 40, respectively. As shown in FIG. 14, the male terminal fitting 30 and the male terminal fitting 30 are fitted, while the backlash restricting piece 43 provided in the second housing 40 enters the restricting piece insertion hole 214 of the first housing 20. The backlash restricting piece 43 that has entered the restricting piece insertion hole 214 of the first housing 20 presses and urges one surface (the lower surface in FIG. 14) of the female terminal fitting 10 in the first housing 20, thereby Suppresses 10 rattles.
　即ち、本実施形態のコネクタ１では、雌端子金具１０のガタ付きの抑止は、第２ハウジング４０の筒状部４１の内底面４１ｂに突設されたガタ規制片４３によって行われ、第２ハウジング４０自体は単一部品で済むため、構成部品の増加を招くことがない。 That is, in the connector 1 of the present embodiment, the rattling of the female terminal fitting 10 is performed by the backlash regulating piece 43 protruding from the inner bottom surface 41b of the cylindrical portion 41 of the second housing 40, and the second housing Since 40 itself may be a single component, the number of components does not increase.
　また、第２ハウジング４０に設けられるガタ規制片４３は、当該第２ハウジング４０への雄端子金具３０の挿抜には何ら関与せず、また、第１ハウジング２０への雌端子金具１０の挿抜にも関与しない。即ち、ガタ規制片４３は、それぞれの第１及び第２ハウジング２０，４０における各雌雄端子金具１０，３０の挿抜時には、いずれの雌雄端子金具１０，３０にも接触しないため、各雌雄端子金具１０，３０の挿抜に大きな操作力が必要となることもない。従って、各雌雄端子金具１０，３０の挿抜性の悪化といった問題を招くこともない。 Further, the backlash restricting piece 43 provided in the second housing 40 is not involved in the insertion / extraction of the male terminal fitting 30 to / from the second housing 40 and is used for the insertion / extraction of the female terminal fitting 10 to / from the first housing 20. Also not involved. That is, the backlash restricting piece 43 does not contact any of the male and female terminal fittings 10 and 30 when the male and female terminal fittings 10 and 30 are inserted and removed from the first and second housings 20 and 40, respectively. , 30 does not require a large operating force. Therefore, the problem of deterioration of the insertion / extraction of the male and female terminal fittings 10 and 30 does not occur.
　従って、本実施形態のコネクタ１では、構成部品の増加や端子金具の挿抜性の悪化といった問題を招くことなく、振動環境下における雌雄端子金具１０，３０のガタ付きを抑制して、安定した電気的接続性能を維持することができる。 Therefore, in the connector 1 according to the present embodiment, the rattling of the male and female terminal fittings 10 and 30 in a vibration environment is suppressed without causing problems such as an increase in the number of components and the deterioration of the insertion / extraction characteristics of the terminal fittings. Connection performance can be maintained.
　また、本実施形態のコネクタ１の場合、図１５に示すように、第１ハウジング２０の雌端子収容孔２１１に挿入された雌端子金具１０が嵌合途中で停止した半嵌合状態の場合、端子係止ランス２１３が規制片挿入孔２１４内に撓んで突出している。そのため、半嵌合状態の第１ハウジング２０と第２ハウジング４０とを嵌合接続しようとすると、規制片挿入孔２１４内に進入する第２ハウジング４０のガタ規制片４３が、規制片挿入孔２１４内に撓んで突出している端子係止ランス２１３と衝突し、ハウジング相互の嵌合を完了させることができない。 Further, in the case of the connector 1 of the present embodiment, as shown in FIG. 15, when the female terminal fitting 10 inserted into the female terminal receiving hole 211 of the first housing 20 is in a half-fitted state where it is stopped during fitting, The terminal locking lance 213 is bent and protrudes into the restriction piece insertion hole 214. Therefore, when the first housing 20 and the second housing 40 in the half-fitted state are to be fitted and connected, the play restricting piece 43 of the second housing 40 that enters the restricting piece insertion hole 214 is moved into the restricting piece insertion hole 214. It collides with the terminal locking lance 213 which is bent and protrudes inward, and the fitting between the housings cannot be completed.
　即ち、ガタ規制片４３が雌端子金具１０の半嵌合状態を検知する半嵌合検知機構として機能し、雌端子金具１０の半嵌合状態の見落としを防止することができる。 That is, the backlash restricting piece 43 functions as a half-fitting detection mechanism that detects the half-fitted state of the female terminal fitting 10 and can prevent the half-fitted state of the female terminal fitting 10 from being overlooked.
　また、本実施形態のコネクタ１の場合、図１３に示すように、ガタ規制片４３が端子先端部３１の先端よりも先方に突出しているため、第２ハウジング４０の保管時や運搬時において、外部機材等が筒状部４１内に進入しても、雄端子金具３０の舌片状の端子先端部３１と外部機材等との接触が、ガタ規制片４３により防がれる。即ち、ガタ規制片４３が雄端子金具３０の端子先端部３１を保護し、端子先端部３１の変形や破損を防止することができる。 Further, in the case of the connector 1 of the present embodiment, as shown in FIG. 13, the backlash restricting piece 43 protrudes further forward than the tip of the terminal tip 31, so that the second housing 40 can be stored or transported. Even if an external device or the like enters the cylindrical portion 41, contact between the tongue-shaped terminal tip portion 31 of the male terminal fitting 30 and the external device or the like is prevented by the backlash regulating piece 43. That is, the play restricting piece 43 protects the terminal tip portion 31 of the male terminal fitting 30 and can prevent the terminal tip portion 31 from being deformed or damaged.
