この基板コネクタ１００は、回路基板２００の上に載置される樹脂製のコネクタハウジング１１０と、該コネクタハウジング１１０に埋設装備された針状の複数の雄端子金具１２０と、を備える。 The board connector 100 includes a resin connector housing 110 placed on the circuit board 200 and a plurality of needle-shaped male terminal fittings 120 embedded in the connector housing 110.

各雄端子金具１２０は、その一端１２１がコネクタハウジング１１０内に位置している。そして、雄端子金具１２０の他端１２２は、コネクタハウジング１１０の後端から延出した後、回路基板２００側に折り曲げられ、回路基板２００に形成されたスルーホール２０１に挿通される。 One end 121 of each male terminal fitting 120 is located in the connector housing 110. The other end 122 of the male terminal fitting 120 extends from the rear end of the connector housing 110, is then bent toward the circuit board 200, and is inserted into the through hole 201 formed in the circuit board 200.

また、外部機器からのケーブルを回路基板２００の接点パターンに導通接続させるには、機器側コネクタを基板コネクタ１００に嵌合させて、それぞれのコネクタに保持されている端子金具相互を雌雄嵌合させる必要があるが、端子金具相互を雌雄嵌合させる際に、端子相互の衝突やこじりにより端子金具の破損を招くおそれがあった。 Further, in order to electrically connect a cable from an external device to the contact pattern of the circuit board 200, the device-side connector is fitted to the board connector 100, and the terminal fittings held by each connector are fitted to each other. Although it is necessary, when fitting the male and female terminal fittings, there is a possibility that the terminal fittings may be damaged due to the collision or twisting between the terminals.

そこで、本発明の目的は、上記課題を解消することに係り、回路基板に対して手間のかかる半田付け作業が不要で、しかも、接続時に衝突やこじりによる端子金具の破損を招くおそれがなく、外部機器からのケーブルに接続された端子金具を簡単に回路基板上の接点パターンに導通接続させることのできる基板コネクタを提供することにある。 Therefore, the purpose of the present invention is to eliminate the above-mentioned problems, and it does not require troublesome soldering work to the circuit board, and there is no risk of causing damage to the terminal fitting due to collision or twisting at the time of connection, It is an object of the present invention to provide a board connector that can easily connect a terminal fitting connected to a cable from an external device to a contact pattern on a circuit board.

The base end is provided with a terminal fitting portion that is slidably fitted on the tip of the terminal fitting and slidably connected to the terminal fitting, and is connected to the contact pattern by contacting the contact pattern at the tip. A relay pin terminal having a contact terminal portion to be
A body fitting portion connected to the tip of the connector body, and the relay pin terminal fitted and connected to the terminal fitting when the body fitting portion is connected to the tip of the connector body are slidably received. A plurality of pin terminal receiving holes, a front holder,
The relay pin terminal in the pin terminal accommodation hole is arranged at the tip of the pin terminal accommodation hole so that the contact terminal portion of the relay pin terminal protrudes from the front end of the front holder. A spring member biased to the side,

The relay pin terminal has a structure in which a flange portion that receives the urging force of the spring member is formed in an intermediate portion of a straight rod-shaped body, and a distal end side of the flange portion functions as the contact terminal portion, and the flange portion Than the base end side functions as the terminal fitting part,
The terminal fitting board connector, characterized in that the terminal fitting portion is a female terminal fitting which fits slidably.

上記（１）の構成によれば、まず、ピン端子収容孔に中継ピン端子とばね部材とを収容したフロントホルダを、コネクタ本体の先端に接続して、基端が端子金具に雌雄嵌合する中継ピン端子の先端が、フロントホルダの先端から突出した状態のコネクタ組立体を得る。次いで、このコネクタ組立体を、回路基板に固定されているコネクタ受け部材に係止させると、中継ピン端子の先端が回路基板上の接点パターンに押圧され、中継ピン端子を介して、コネクタ本体内の端子金具と回路基板上の接点パターンとが導通接続された状態が得られる。 According to the configuration of (1) above, first, the front holder that accommodates the relay pin terminal and the spring member in the pin terminal accommodation hole is connected to the distal end of the connector body, and the base end is fitted into the terminal fitting with male and female. A connector assembly is obtained with the end of the relay pin terminal protruding from the end of the front holder. Next, when this connector assembly is locked to the connector receiving member fixed to the circuit board, the tip of the relay pin terminal is pressed against the contact pattern on the circuit board, and the inside of the connector main body is connected via the relay pin terminal. The terminal fitting and the contact pattern on the circuit board are conductively connected.

即ち、上記（１）の構成によれば、外部機器からのケーブルに接続された端子金具と、回路基板上の接点パターンとの導通接続は、基端が端子金具に摺動可能に嵌合した中継ピン端子の先端を、接点パターンに押圧接触させることにより実現する。 That is, according to the configuration of (1) above, the base end of the terminal fitting connected to the cable from the external device and the contact pattern on the circuit board is slidably fitted to the terminal fitting. This is realized by pressing the tip of the relay pin terminal against the contact pattern.

そのため、外部機器からのケーブルを回路基板の接点パターンに導通接続する際に、回路基板に対して手間のかかる半田付け作業が不要である。 Therefore, when the cable from the external device is conductively connected to the contact pattern of the circuit board, a troublesome soldering operation to the circuit board is unnecessary.

しかも、中継ピン端子と回路基板上の接点パターンとの導通接続は、互いの突き合わせによる押圧接触によって行っており、接続時に衝突やこじりの発生原因となる端子金具相互の雌雄嵌合が存在しないため、接続時に衝突やこじりによる端子金具の破損を招くおそれもない。 In addition, the conductive connection between the relay pin terminal and the contact pattern on the circuit board is performed by pressing contact with each other, and there is no male / female fitting between the terminal fittings that causes collision or twisting at the time of connection. In addition, there is no risk of damage to the terminal fitting due to collision or twisting during connection.

従って、外部機器からのケーブルに接続された端子金具を簡単に回路基板上の接点パターンに導通接続させることができる。 Therefore, the terminal fitting connected to the cable from the external device can be easily connected to the contact pattern on the circuit board.

また、端子金具に摺動可能に嵌合接続される中継ピン端子には、ばね部材による付勢力が作用していて、接点パターンに対して所定の接触圧が確保される。そのため、コネクタ本体の寸法誤差や、組立誤差をばね部材の変形によって吸収することができ、寸法誤差や、組立誤差の影響を受けずに安定した電気的接続状態を確保することができ、接点パターンと端子金具との接続信頼性を向上させることができる。 Further, a biasing force by a spring member acts on the relay pin terminal slidably fitted and connected to the terminal fitting, and a predetermined contact pressure is secured to the contact pattern. Therefore, the dimensional error and assembly error of the connector body can be absorbed by the deformation of the spring member, and a stable electrical connection state can be secured without being affected by the dimensional error and assembly error. And the connection reliability between the terminal fittings can be improved.

上記（２）の構成によれば、中継ピン端子は、棒状体の中間部に鍔部を形成した単純構造であるため、製造が容易で、製造コストの増加を抑止することができる。 According to the configuration of (2) above, the relay pin terminal has a simple structure in which the flange portion is formed in the middle portion of the rod-like body, and therefore it is easy to manufacture and the increase in manufacturing cost can be suppressed.

しかも、ケーブルに接続される端子金具には、棒状体が嵌合可能な既存の雌型端子金具を流用することができ、既存部品の流用による製造コストの低減を図ることもできる。 Moreover, existing female terminal fittings that can be fitted with rod-like bodies can be used for the terminal fittings connected to the cables, and the manufacturing cost can be reduced by diverting existing parts.

本発明による基板コネクタによれば、外部機器からのケーブルに接続された端子金具と、回路基板上の接点パターンとの導通接続は、基端が端子金具に摺動可能に嵌合した中継ピン端子の先端を、接点パターンに押圧接触させることにより実現する。 According to the board connector of the present invention, the conductive connection between the terminal fitting connected to the cable from the external device and the contact pattern on the circuit board is a relay pin terminal whose base end is slidably fitted to the terminal fitting. This is realized by pressing the tip of the contact with the contact pattern.

次に、本実施形態の基板コネクタ１の回路基板１０への組み付け手順を説明する。
まず、フロントホルダ６０のピン端子収容孔６２に、中継ピン端子５０及びばね部材７０を装着する。 Next, a procedure for assembling the board connector 1 of the present embodiment to the circuit board 10 will be described.
First, the relay pin terminal 50 and the spring member 70 are attached to the pin terminal accommodation hole 62 of the front holder 60.

次いで、中継ピン端子５０及びばね部材７０を装着したフロントホルダ６０を、図７〜図１１に示すように、コネクタ本体４０の先端に仮係止させる。このとき、コネクタ本体４０には、端子金具３０は装着されていない。従って、コネクタ本体４０の先端にフロントホルダ６０を仮係止する際には、大きな操作力は必要なく、容易に仮係止状態にすることができる。 Next, the front holder 60 to which the relay pin terminal 50 and the spring member 70 are attached is temporarily locked to the tip of the connector main body 40 as shown in FIGS. At this time, the terminal fitting 30 is not attached to the connector main body 40. Therefore, when the front holder 60 is temporarily locked to the tip of the connector main body 40, a large operating force is not required and the temporary locking state can be easily achieved.

次いで、図１２に示すように、フロントホルダ６０が仮係止されているコネクタ本体４０に、ケーブル２０が接続されている端子金具３０を挿入装着する。端子金具３０の挿入は、端子金具３０が端子収容孔４１内のランス４４に係止されるまで、行う。端子金具３０の装着が完了したら、コネクタ本体４０を更にフロントホルダ６０内に押し込んで、図１３〜図１５に示すようフロントホルダ６０がコネクタ本体４０に本係止された状態にする。 Next, as shown in FIG. 12, the terminal fitting 30 to which the cable 20 is connected is inserted and attached to the connector main body 40 to which the front holder 60 is temporarily locked. The terminal fitting 30 is inserted until the terminal fitting 30 is locked to the lance 44 in the terminal accommodating hole 41. When the mounting of the terminal fitting 30 is completed, the connector main body 40 is further pushed into the front holder 60 so that the front holder 60 is fully locked to the connector main body 40 as shown in FIGS.

フロントホルダ６０がコネクタ本体４０に本係止された状態では、図１７に示すように、端子嵌合部５１が所定の深さまで箱部３３内に挿入された状態になり、端子嵌合部５１とばね片３３ａとの間に、安定した電気的接続に必要となる充分な接触面が確保される。また、本係止状態では、図１７に示すように、コネクタ本体４０の先端面４０ａが、ピン端子収容孔６２内のばね部材７０に当接し、ばね部材７０がコネクタ本体４０の先端面と鍔部５３との間に挟まれた状態になる。ばね部材７０は、図１７に示すように、当接端子部５２が最大限にフロントホルダ６０の先端から突出するように、中継ピン端子５０を突出方向に付勢する。 In the state where the front holder 60 is permanently locked to the connector main body 40, the terminal fitting portion 51 is inserted into the box portion 33 to a predetermined depth as shown in FIG. A sufficient contact surface required for stable electrical connection is ensured between the spring piece 33a and the spring piece 33a. Further, in the final locked state, as shown in FIG. 17, the distal end surface 40 a of the connector main body 40 abuts on the spring member 70 in the pin terminal accommodating hole 62, and the spring member 70 is in contact with the distal end surface of the connector main body 40. It is in a state of being sandwiched between the part 53. As shown in FIG. 17, the spring member 70 urges the relay pin terminal 50 in the protruding direction so that the contact terminal portion 52 protrudes from the front end of the front holder 60 to the maximum extent.

次いで、図１８〜図２１に示すように、回路基板１０にコネクタ受け部材８０を固定する。 Next, as shown in FIGS. 18 to 21, the connector receiving member 80 is fixed to the circuit board 10.

次いで、図２２に矢印Ｙ１で示すように、フロントホルダ６０が本係止されたコネクタ本体４０を、コネクタ受け部材８０に挿入し、コネクタ本体４０の受け部材連結突起４３をコネクタ受け部材８０のコネクタ連結部８３に係合させることで、コネクタ本体４０をコネクタ受け部材８０に係止させる。これで、コネクタ本体４０の回路基板１０への接続は完了である。 Next, as indicated by an arrow Y 1 in FIG. 22, the connector main body 40 to which the front holder 60 is permanently locked is inserted into the connector receiving member 80, and the receiving member connecting protrusion 43 of the connector main body 40 is connected to the connector of the connector receiving member 80. By engaging with the connecting portion 83, the connector body 40 is locked to the connector receiving member 80. Thus, the connection of the connector main body 40 to the circuit board 10 is completed.

コネクタ本体４０がコネクタ受け部材８０に係止されると、フロントホルダ６０の先端から突出していた中継ピン端子５０の当接端子部５２は、図２４〜図２６に示すように、先端を回路基板１０の接点パターン１１に押圧接触して、接点パターン１１に導通接続された状態になる。また、当接端子部５２が接点パターン１１に押圧接触する際には、ばね部材７０が図２６の矢印Ｙ２で示す方向に圧縮変形し、中継ピン端子５０を接点パターン１１と押圧状態に保つ所定の付勢力を発生する。 When the connector main body 40 is locked to the connector receiving member 80, the contact terminal portion 52 of the relay pin terminal 50 that protrudes from the front end of the front holder 60 has its front end connected to the circuit board as shown in FIGS. The contact pattern 11 is pressed into contact with the contact pattern 11 and is electrically connected to the contact pattern 11. Further, when the contact terminal portion 52 is in press contact with the contact pattern 11, the spring member 70 is compressed and deformed in the direction indicated by the arrow Y <b> 2 in FIG. 26 to keep the relay pin terminal 50 in a pressed state with the contact pattern 11. Generates an energizing force.

以上に説明した一実施形態の基板コネクタ１によれば、まず、ピン端子収容孔６２に中継ピン端子５０とばね部材７０とを収容したフロントホルダ６０を、コネクタ本体４０の先端に接続して、端子金具３０が雌雄嵌合する中継ピン端子５０の先端がフロントホルダ６０の先端から突出した状態のコネクタ組立体を得る。 According to the board connector 1 of the embodiment described above, first, the front holder 60 in which the relay pin terminal 50 and the spring member 70 are accommodated in the pin terminal accommodation hole 62 is connected to the tip of the connector body 40, A connector assembly is obtained in a state in which the end of the relay pin terminal 50 into which the terminal fitting 30 is male and female is projected from the front end of the front holder 60.

次いで、このコネクタ組立体を、回路基板１０に固定されているコネクタ受け部材８０に係止させると、中継ピン端子５０の先端が回路基板１０上の接点パターン１１に押圧され、中継ピン端子５０を介して、コネクタ本体４０内の端子金具３０と回路基板１０上の接点パターン１１とが導通接続された状態が得られる。 Next, when the connector assembly is locked to the connector receiving member 80 fixed to the circuit board 10, the tip of the relay pin terminal 50 is pressed against the contact pattern 11 on the circuit board 10, and the relay pin terminal 50 is Thus, a state in which the terminal fitting 30 in the connector main body 40 and the contact pattern 11 on the circuit board 10 are conductively connected is obtained.

即ち、一実施形態の基板コネクタ１によれば、外部機器からのケーブル２０に接続された端子金具３０と、回路基板１０上の接点パターン１１との導通接続は、端子金具３０に摺動可能に嵌合した中継ピン端子５０の先端を接点パターン１１に押圧接触させることにより実現する。 That is, according to the board connector 1 of the embodiment, the conductive connection between the terminal fitting 30 connected to the cable 20 from the external device and the contact pattern 11 on the circuit board 10 is slidable on the terminal fitting 30. This is realized by pressing and contacting the end of the fitted relay pin terminal 50 to the contact pattern 11.

そのため、外部機器からのケーブル２０を回路基板１０の接点パターン１１に導通接続する際に、回路基板１０に対して手間のかかる半田付け作業が不要である。 Therefore, when the cable 20 from the external device is conductively connected to the contact pattern 11 of the circuit board 10, a troublesome soldering operation to the circuit board 10 is unnecessary.

しかも、中継ピン端子５０と回路基板１０上の接点パターン１１との導通接続は、互いの突き合わせによる押圧接触によって行っており、接続時に衝突やこじりの発生原因となる端子金具相互の雌雄嵌合が存在しないため、接続時に衝突やこじりによる端子金具の破損を招くおそれもない。 In addition, the conductive connection between the relay pin terminal 50 and the contact pattern 11 on the circuit board 10 is performed by pressing contact with each other, and there is a male-female fitting between the terminal fittings that causes collision and twisting at the time of connection. Since it does not exist, there is no risk of damage to the terminal fitting due to collision or twisting during connection.

従って、外部機器からのケーブル２０に接続された端子金具３０を簡単に回路基板１０上の接点パターン１１に導通接続させることができる。 Accordingly, the terminal fitting 30 connected to the cable 20 from the external device can be easily connected to the contact pattern 11 on the circuit board 10.

また、端子金具３０に摺動可能に嵌合接続される中継ピン端子５０にはばね部材７０による付勢力が作用していて、接点パターン１１に対して所定の接触圧が確保される。そのため、コネクタ本体４０の寸法誤差や、組立誤差をばね部材７０の変形によって吸収することができ、寸法誤差や、組立誤差の影響を受けずに安定した電気的接続状態を確保することができ、接点パターン１１と端子金具３０との接続信頼性を向上させることができる。 Further, a biasing force by the spring member 70 acts on the relay pin terminal 50 slidably fitted and connected to the terminal fitting 30, and a predetermined contact pressure is secured to the contact pattern 11. Therefore, dimensional errors and assembly errors of the connector main body 40 can be absorbed by deformation of the spring member 70, and a stable electrical connection state can be ensured without being affected by the dimensional errors and assembly errors. Connection reliability between the contact pattern 11 and the terminal fitting 30 can be improved.
