Description

本発明は、半嵌合防止機能を備えた半嵌合防止コネクタに関する。 The present invention relates to a semi-fitting prevention connector having a semi-fitting prevention function.

この種の半嵌合防止コネクタとして、図５と図６に示すものが知られている。この半嵌合防止コネクタ１は、図５と図６に示すように、雌ハウジング３に雌端子４を有すると共に、雌ハウジング３の外側に一対のロックアーム３ａ，３ａを有する雌コネクタ２と、雄ハウジング６に雄端子７を有すると共に、雌コネクタ２に嵌合した際に、ロックアーム３ａのロック突部３ｂが係止される係止凹部６ａを有する雄コネクタ５と、雄ハウジング６の一対のバネ収容部６ｂ，６ｂ内にスライド自在に設けられ、雌コネクタ２の嵌合方向Ａに沿ってスライドする一対のスライド部材８，８と、雌，雄コネクタ２，５の半嵌合時にスライド部材８を雌コネクタ２の反嵌合方向Ｂに付勢して雌，雄コネクタ２，５を離間させる圧縮コイルバネ９と、を備えている。尚、図５及び図６中符号６ｃは、雄ハウジング６のバネ収容部６ｂを覆うカバーである。 As this kind of semi-fitting prevention connector, those shown in FIGS. 5 and 6 are known. As shown in FIGS. 5 and 6, the semi-fitting prevention connector 1 has a female connector 2 having a female terminal 4 in the female housing 3 and a pair of lock arms 3a, 3a on the outside of the female housing 3. A pair of a male connector 5 having a male terminal 7 in the male housing 6 and having a locking recess 6a in which the lock protrusion 3b of the lock arm 3a is locked when fitted to the female connector 2. A pair of slide members 8 and 8 that are slidably provided in the spring accommodating portions 6b and 6b of the female connector 2 and slide along the fitting direction A of the female connector 2 and slide when the female and male connectors 2 and 5 are half-fitted. It includes a compression coil spring 9 that urges the member 8 in the anti-fitting direction B of the female connector 2 to separate the female and male connectors 2 and 5. Reference numeral 6c in FIGS. 5 and 6 is a cover that covers the spring accommodating portion 6b of the male housing 6.

そして、半嵌合（中途嵌合）を防止するために、雌，雄コネクタ２，５の嵌合時の挿入力より圧縮コイルバネ９の反発力を強くすることで、雌コネクタ２のロックアーム３ａのロック突部３ｂと雄コネクタ５の係止凹部６ａとが係止するまで、雌コネクタ２が圧縮コイルバネ９の弾性力（復元力）により雌端子４と雄端子７が接触しない状態まで押し戻され、雌，雄コネクタ２，５の半嵌合において雌端子４と雄端子７が導通しないようになっている。 Then, in order to prevent half-fitting (halfway fitting), the repulsive force of the compression coil spring 9 is made stronger than the insertion force at the time of fitting the female and male connectors 2 and 5, so that the lock arm 3a of the female connector 2 is used. The female connector 2 is pushed back by the elastic force (restoring force) of the compression coil spring 9 until the female terminal 4 and the male terminal 7 do not come into contact with each other until the locking protrusion 3b of the male connector 5 and the locking recess 6a of the male connector 5 are engaged. , The female terminal 4 and the male terminal 7 do not conduct in the half-fitting of the female and male connectors 2 and 5.

特開平１１−１１１３９０号公報Japanese Unexamined Patent Publication No. 11-11139

しかしながら、前記従来の半嵌合防止コネクタ１では、半嵌合防止用の圧縮コイルバネ９を雄コネクタ５の雄ハウジング６に形成されたバネ収容部６ｂに収容するため、構造が複雑となってコネクタ全体が大型となり、その取扱い性が悪かった。 However, in the conventional semi-fitting prevention connector 1, the compression coil spring 9 for preventing semi-fitting is housed in the spring accommodating portion 6b formed in the male housing 6 of the male connector 5, so that the structure becomes complicated and the connector is connected. The whole was large and its handleability was poor.

そこで、本発明は、前記した課題を解決すべくなされたものであり、半嵌合を防止することができ、かつ、コネクタ全体の小型化及び取扱い性の向上を図ることができる半嵌合防止コネクタを提供することを目的とする。 Therefore, the present invention has been made to solve the above-mentioned problems, and it is possible to prevent semi-fitting, and it is possible to reduce the size of the entire connector and improve the handleability. The purpose is to provide a connector.

本発明は、半嵌合を防止する機能を備えた半嵌合防止コネクタであって、隔壁が設けられた一方の筒状のハウジングと前記一方の筒状のハウジングの隔壁の底面側の方向から見た際の中央部の回りに設けられた複数の一方の端子とロックアームを有する一方のコネクタと、隔壁が設けられた他方の筒状のハウジングと前記一方のコネクタに嵌合した際に前記ロックアームのロック部が係止される係止部と前記他方の筒状のハウジングの隔壁の底面側の方向から見た際の中央部の回りに設けられた複数の他方の端子を有する他方のコネクタと、前記両コネクタの前記両隔壁の各底面側の方向から見た際の中央の相対向する位置にそれぞれ設けられて半嵌合時に該両コネクタを反嵌合方向に付勢する磁性体と、を備え、前記両コネクタに設けられた各磁性体は、同極性の磁力を有し、前記ロックアームのロック部が前記他方のコネクタの係止部に係止されるまでの前記両コネクタの半嵌合時に前記各磁性体の同極性の磁力による反発力が働くようにしたことを要旨とする。 The present invention is a semi-fitting prevention connector having a function of preventing semi-fitting, from the direction of the bottom surface side of the partition wall of one tubular housing provided with a partition wall and the one tubular housing. The connector when fitted to one connector having a plurality of terminals and a lock arm provided around the central portion when viewed, and the other tubular housing provided with a partition wall and the one connector. The other having a locking portion to which the locking portion of the lock arm is locked and a plurality of other terminals provided around the central portion when viewed from the bottom surface side of the partition wall of the other tubular housing.

Each of the magnetic bodies provided in the two connectors has a magnetic force of the same polarity, and the both connectors until the lock portion of the lock arm is locked to the locking portion of the other connector. The gist is that the repulsive force due to the magnetic force of the same polarity of each of the magnetic materials acts at the time of half-fitting.

また、本発明の半嵌合防止コネクタは、前記両コネクタに設けられた各磁性体が同極性の磁力を有する磁石からなることを特徴とする。 Further, the semi-fitting prevention connector of the present invention is characterized in that each magnetic material provided in both connectors is made of a magnet having a magnetic force of the same polarity.

本発明によれば、半嵌合防止用のバネ部材の代わりに同極性の磁力を有する磁性体を用いることで、従来のようなバネ部材を収容する部分が不要となり、その分、構造の簡素化を図ることができる。この構造の簡素化により、コネクタ全体の小型化及び取扱い性の向上を図ることができる。 According to the present invention, by using a magnetic material having a magnetic force of the same polarity instead of the spring member for preventing semi-fitting, a portion for accommodating the spring member as in the conventional case becomes unnecessary, and the structure is simplified accordingly. Can be achieved. By simplifying this structure, it is possible to reduce the size of the entire connector and improve the handleability.

Cylindrical and homogeneous magnets (magnetic material) 29, 39 having a repulsive force (magnetic force) that separates both connectors 20 and 30 when the two connectors 20 and 30 are half-fitted until they are locked to 38. It is equipped with.

雌コネクタ２０の円筒状の内側ハウジング２２と円筒状の外側ハウジング２４を仕切る円板状の隔壁２３の底面側の方向から見た際の中央部の回りには、複数の円筒状の雌端子２５を突設してある。各雌端子２５には電線２６が接続されている。 A plurality of cylindrical female terminals 25 are located around the central portion of the disk-shaped partition wall 23 that separates the cylindrical inner housing 22 and the cylindrical outer housing 24 of the female connector 20 when viewed from the bottom surface side. Is projected. An electric wire 26 is connected to each female terminal 25.

また、雌ハウジング２１の外側ハウジング２４の上下部には、各一対のスリット２４ａ，２４ａを形成してあり、この各一対のスリット２４ａ，２４ａ間には、先端にロック突起２８を有した一対のロックアーム２７，２７を撓み変形自在に一体突出形成してある。 Further, a pair of slits 24a, 24a are formed in the upper and lower portions of the outer housing 24 of the female housing 21, and a pair of slits 24a, 24a having a lock protrusion 28 at the tip thereof are formed between the pair of slits 24a, 24a. The lock arms 27, 27 are flexibly and deformably integrally projected.

さらに、雌ハウジング２１の隔壁２３の底面側の方向から見た際の中央には、例えばＮ極の磁性を有した円柱状の磁石２９の基部２９ａを埋設してある。 Further, in the center of the female housing 21 when viewed from the bottom surface side of the partition wall 23, for example, a base 29a of a columnar magnet 29 having N-pole magnetism is embedded.

雄コネクタ３０の円筒状のフード部３２の円板状の隔壁３３の底面側の方向から見た際の中央部の回りには、複数のピン状の雄端子３５を突設してある。各雄端子３５には電線３６が接続されている。 A plurality of pin-shaped male terminals 35 are projected around the central portion of the cylindrical hood portion 32 of the male connector 30 when viewed from the bottom surface side of the disk-shaped partition wall 33. An electric wire 36 is connected to each male terminal 35.

また、雄ハウジング３１の隔壁３３の底面側の方向から見た際の中央には、例えばＮ極の磁性を有した円柱状の磁石３９の基部３９ａを埋設してある。雌コネクタ２０の磁石２９と雄コネクタ３０の磁石３９は共に同極性を有するため、互いに近接すると反発し合うようになっている。尚、図３において、雄コネクタ３０に対して雌コネクタ２０を反嵌合方向（嵌合方向の逆方向）Ｂに付勢して雌，雄コネクタ２０，３０を離間させる磁石２９，３９の反発力が働く距離（空間）を符号Ｈで示す。 Further, in the center of the male housing 31 when viewed from the bottom surface side of the partition wall 33, for example, a base 39a of a columnar magnet 39 having N-pole magnetism is embedded. Since the magnet 29 of the female connector 20 and the magnet 39 of the male connector 30 both have the same polarity, they repel each other when they are close to each other. In FIG. 3, the repulsion of the magnets 29 and 39 that urge the female connector 20 against the male connector 30 in the anti-fitting direction (opposite direction of the mating direction) B to separate the female and male connectors 20 and 30. The distance (space) in which the force acts is indicated by the symbol H.

さらに、雄ハウジング３１の円筒状のフード部３２の上下部には、ロックアーム２７のロック突起２８が接触して摺動する長溝凹状のロックアーム接触部３７をそれぞれ形成してある。この各長溝凹状のロックアーム接触部３７の中央には、ロックアーム２７のロック突起２８が係止・離脱される係止凹部３８を形成してある。 Further, on the upper and lower portions of the cylindrical hood portion 32 of the male housing 31, a long groove concave lock arm contact portion 37 on which the lock protrusion 28 of the lock arm 27 is in contact and slides is formed. At the center of each of the long groove concave lock arm contact portions 37, a locking recess 38 is formed in which the lock protrusion 28 of the lock arm 27 is locked / detached.

以上実施形態の半嵌合防止コネクタ１０によれば、図３に示すように、雌コネクタ２０と雄コネクタ３０の嵌合開始時に、雄ハウジング３１のロックアーム接触部３７により雌コネクタ２０のロックアーム２７が持ち上げられる。雌ハウジング２１を雄ハウジング３１の方向に移動させることにより、雌ハウジング２１のロックアーム２７のロック突起２８と雄ハウジング３１の係止凹部３８に係止することで、図４に示すように、完全嵌合状態となる。 According to the semi-fitting prevention connector 10 of the above embodiment, as shown in FIG. 3, when the fitting of the female connector 20 and the male connector 30 is started, the lock arm contact portion 37 of the male housing 31 causes the lock arm of the female connector 20 to be locked. 27 is lifted. By moving the female housing 21 toward the male housing 31, the lock protrusion 28 of the lock arm 27 of the female housing 21 and the locking recess 38 of the male housing 31 are locked, thereby completely as shown in FIG. It will be in a mated state.

雌ハウジング２１と雄ハウジング３１にそれぞれ組み込まれた磁石２９，３９を同極性にすることにより、雌，雄コネクタ２０，３０の半嵌合（中途嵌合）時に、雌コネクタ２０と雄コネクタ３０の離脱力を超える反発力が発生する。これにより、両コネクタ２０，３０が完全嵌合状態とならない限り、磁石２９，３９の反発力によって、雌端子２５と雄端子３５は接触しない位置まで戻されるため、半嵌合による雌コネクタ２０の雌端子２５と雄コネクタ３０の雄端子３５の導通を防止することができる。 By making the magnets 29 and 39 incorporated in the female housing 21 and the male housing 31 having the same polarity, the female connector 20 and the male connector 30 can be half-fitted (half-fitted) between the female and male connectors 20 and 30. A repulsive force that exceeds the detachment force is generated. As a result, unless both connectors 20 and 30 are in a completely fitted state, the female terminal 25 and the male terminal 35 are returned to positions where they do not come into contact with each other due to the repulsive force of the magnets 29 and 39. It is possible to prevent conduction between the female terminal 25 and the male terminal 35 of the male connector 30.

また、磁石２９，３９を用いることで、従来のコネクタに設けられているバネ部材を収容する部分が不要となるため、その分、構造の簡素化を図ることができる。この構造の簡素化により、コネクタ全体を小型化することができ、かつ、その取扱い性を向上させることができる。 Further, by using the magnets 29 and 39, the portion for accommodating the spring member provided in the conventional connector becomes unnecessary, so that the structure can be simplified accordingly. By simplifying this structure, the entire connector can be miniaturized and its handleability can be improved.

尚、前記実施形態によれば、Ｎ極同士の磁石で反発させたが、Ｓ極同士の磁石で反発させるようにしても良い。また、磁性体として円柱状の磁石を用いたが、矩形体状の磁石でも良い。 According to the above embodiment, the magnets of the N poles repel each other, but the magnets of the S poles may repel each other. Although using a cylindrical magnet as a magnetic material, but it may also rectangular-like magnet.
