Description

コネクタ式スクリューレス端子台Connector type screwless terminal block
　本開示は、ピンコンタクトに対して接続可能なソケットコンタクトを備えるコネクタ式スクリューレス端子台に関する。 The present disclosure relates to a connector-type screwless terminal block including a socket contact connectable to a pin contact.
　従来、回路基板への電気配線の接続にスクリューレス端子台が使用されている。スクリューレス端子台は、ねじが不要の端子台であり、電線の被覆をむいてダイレクトに結線・解除作業がワンタッチで行える。また、スクリューレス端子台には、回路基板用途のものがあり、回路基板に直接固定するタイプとコネクタで分離できるタイプとの二つがある。後者のソケットコンタクトを備えるスクリューレス端子台は、例えば特許文献１または２において開示がある。 ス ク リ ュ ー Conventionally, screwless terminal blocks have been used to connect electrical wiring to circuit boards. The screwless terminal block is a terminal block that does not require screws, and can be directly connected and released with a single touch by stripping the wires. Further, there are screwless terminal blocks for use on a circuit board, and there are two types: a type directly fixed to the circuit board and a type that can be separated by a connector. A screwless terminal block provided with the latter socket contact is disclosed in, for example, Patent Document 1 or 2.
特表２００９－５３１８１５号公報Japanese Patent Publication No. 2009-531815 特開２００７－２５８０２８号公報JP 2007-258028 A
　特許文献１または２に開示されたスクリューレス端子台（コネクタ）は、一方の端部に端子台を有し、他方の端部にソケットコンタクトを有している。端子台は挿入される電気配線を、ソケットコンタクトはピンコンタクトを、二つの接点端子で狭持するようになっている。 ス ク リ ュ ー The screwless terminal block (connector) disclosed in Patent Document 1 or 2 has a terminal block at one end and a socket contact at the other end. The terminal block holds the electric wiring to be inserted, the socket contact holds the pin contact, and the two contact terminals hold the pin contact.
　特許文献１または２に開示の構成では、端子台における一方の接点端子およびソケットコンタクトにおける一方の接点端子は、同一の接点部材のそれぞれの端部に形成されている。したがって、上記接点部材によって、端子台に挿入される電気配線とソケットコンタクトに挿入されるピンコンタクトとの電気導通が得られるようになっている。 In the configuration disclosed in Patent Document 1 or 2, one contact terminal of the terminal block and one contact terminal of the socket contact are formed at respective ends of the same contact member. Therefore, the contact member can provide electrical continuity between the electric wiring inserted into the terminal block and the pin contact inserted into the socket contact.
　一方、端子台における他方の接点端子は、電気配線を安定して保持できるようにバネ性の高い（バネ定数の大きい）板バネ部材（例えばＳＵＳバネ）とされている。また、ソケットコンタクトは、両方の接点端子とも、電気伝導性の高いバネ用銅材（例えばリン青銅）を使用することが一般的である。また、ソケットコンタクトにおける両方の接点端子は、同一の接点部材において形成されている。 On the other hand, the other contact terminal of the terminal block is a leaf spring member (for example, a SUS spring) having a high spring property (having a large spring constant) so that electric wiring can be stably held. In addition, the socket contact generally uses a copper material for a spring (for example, phosphor bronze) having high electrical conductivity for both contact terminals. Further, both contact terminals of the socket contact are formed of the same contact member.
　ソケットコンタクトにおいて、接触信頼性を確保する（ピンコンタクトに対する十分な通電性を得る）ためには、両方の接点端子間において高い接触圧力を付与することが重要である。特許文献１または２に開示の構成においては、ソケットコンタクトの両方の接点端子をバネ用銅材としているが、バネ用銅材は電気伝導性の面では良好である一方、バネ性の面ではＳＵＳなどと比べて低く、接点端子間の接触圧力を高くすることが難しい。そして、ユーザのニーズによっては、より高い接触信頼性を得るために、接点端子間の接触圧力を高くしたソケットコンタクトが求められている。 In socket contacts, it is important to apply a high contact pressure between both contact terminals in order to ensure contact reliability (obtain sufficient electrical conductivity for pin contacts). In the configuration disclosed in Patent Literature 1 or 2, both contact terminals of the socket contact are made of a copper material for a spring, but the copper material for a spring is good in terms of electrical conductivity, but is SUS in terms of a spring property. Therefore, it is difficult to increase the contact pressure between the contact terminals. Depending on the needs of the user, a socket contact with a high contact pressure between the contact terminals is required in order to obtain higher contact reliability.
　尚、特許文献１には、追加部材を用いてソケットコンタクトの接点端子間の接触圧力を高くする構成も開示されているが、この構成では部材点数が増加するといった問題がある。 Patent Document 1 discloses a configuration in which the contact pressure between the contact terminals of the socket contact is increased by using an additional member. However, this configuration has a problem that the number of members increases.
　本開示は、上記課題に鑑みてなされたものであり、部材点数を増やすことなく、高い接触信頼性が得らえるソケットコンタクトを有するコネクタ式スクリューレス端子台を提供することを目的とする。 The present disclosure has been made in view of the above problems, and has as its object to provide a connector-type screwless terminal block having a socket contact capable of obtaining high contact reliability without increasing the number of members.
　上記の課題を解決するために、本開示の第１の態様であるコネクタ式スクリューレス端子台は、一端にピンコンタクトに対して接続可能なソケットコンタクトを有し、他端にスクリューレス端子台を有しているコネクタ式スクリューレス端子台であって、前記スクリューレス端子台における一方の接点端子と、前記ソケットコンタクトにおける一方の接点端子とが、同一の接点部材のそれぞれの端部に形成されており、前記スクリューレス端子台における他方の接点端子は、前記一方の接点端子との間で電気配線を保持する板バネ部材の一端部に形成されており、前記板バネ部材の他端部は、前記ソケットコンタクト側に延長されており、前記ソケットコンタクトの他方の接点端子を形成していることを特徴としている。 In order to solve the above problems, a connector-type screwless terminal block according to a first aspect of the present disclosure has a socket contact connectable to a pin contact at one end, and a screwless terminal block at the other end.

　以下、本開示の一側面に係る実施の形態について、図面を参照して説明する。図１は、本実施の形態に係るコネクタ１０の斜視図である。図２は、コネクタ１０におけるピンコンタクト１０２とソケットコンタクト２１０との嵌合位置での断面図である。尚、図１では、コネクタ１０が４極の多極コネクタである場合を例示しているが、コネクタの極数は特に限定されるものではない。また、コネクタ１０は単極コネクタであってもよい。 Hereinafter, an embodiment according to one aspect of the present disclosure will be described with reference to the drawings. FIG. 1 is a perspective view of a connector 10 according to the present embodiment. FIG. 2 is a cross-sectional view of the connector 10 at a position where the pin contact 102 and the socket contact 210 are fitted. Although FIG. 1 illustrates a case where the connector 10 is a four-pole multi-pole connector, the number of poles of the connector is not particularly limited. Further, the connector 10 may be a single-pole connector.
　コネクタ１０は、プラグ部品１００とソケット部品２００とによって構成されている。ソケット部品２００は、本発明の「コネクタ式スクリューレス端子台」の一例である。プラグ部品１００は、プラグ用ハウジング１０１とピンコンタクト１０２とによって構成されており、例えば、図示しない回路基板などに設けられるものである。プラグ部品１００では、プラグ用ハウジング１０１に形成された空間１０１ａ内にピンコンタクト１０２が収容され、ピンコンタクト１０２の一端（ソケットコンタクト２１０との接続側）が空間１０１ａ内で露出する。空間１０１ａは、少なくともソケット部品２００の挿入側が開口している。 The connector 10 includes a plug component 100 and a socket component 200. The socket component 200 is an example of the “connector-type screwless terminal block” of the present invention. The plug component 100 includes a plug housing 101 and a pin contact 102, and is provided on, for example, a circuit board (not shown). In the plug component 100, the pin contact 102 is accommodated in a space 101a formed in the plug housing 101, and one end of the pin contact 102 (the side connected to the socket contact 210) is exposed in the space 101a. The space 101a is open at least on the insertion side of the socket component 200.
　ソケット部品２００は、その一端にソケットコンタクト２１０を有しており、他端にスクリューレス端子台２２０を有している。 The socket component 200 has a socket contact 210 at one end and a screwless terminal block 220 at the other end.
　さらに、ソケット部品２００の構成についてより詳細に説明する。ソケット部品２００は、大略的には、ソケット本体２０１とロックレバー２３０とによって構成されている。ロックレバー２３０は、ソケット本体２０１に設けられた支軸２０１ａ（図１参照）の周りで回動可能となるように、ソケット本体２０１に対して取り付けられている。ロックレバー２３０は、本発明の「操作可動部材」の一例である。 Further, the configuration of the socket component 200 will be described in more detail. The socket component 200 generally includes a socket body 201 and a lock lever 230. The lock lever 230 is attached to the socket body 201 so as to be rotatable around a support shaft 201a (see FIG. 1) provided on the socket body 201. The lock lever 230 is an example of the “operation movable member” of the present invention.
　ソケット本体２０１は、図２に示すように、ソケットハウジング２０２、カバーハウジング２０３、接点部材２０４および板バネ部材２０５を具備して構成されている。すなわち、ソケット本体２０１は、ソケットハウジング２０２およびカバーハウジング２０３からなる筐体内に接点部材２０４および板バネ部材２０５を収容している。 (2) As shown in FIG. 2, the socket body 201 includes a socket housing 202, a cover housing 203, a contact member 204, and a leaf spring member 205. That is, the socket body 201 accommodates the contact member 204 and the leaf spring member 205 in a housing including the socket housing 202 and the cover housing 203.
　接点部材２０４は、金属などの導電材にて形成されており、その一端がソケットコンタクト２１０における第１接点端子２０４ａとなり、他端がスクリューレス端子台２２０における第３接点端子２０４ｂとなる。尚、接点部材２０４には、バネ性を有すると共に、高い電気伝導性を有するバネ用銅材（例えば、リン青銅）を使用することが好ましい。板バネ部材２０５は、バネ性の強い材料（例えばＳＵＳ）にて形成されており、その一端がソケットコンタクト２１０における第２接点端子２０５ａとなり、他端がスクリューレス端子台２２０における第４接点端子２０５ｃとなる。また、板バネ部材２０５における第２接点端子２０５ａの先端にはフック部２０５ｂが形成されている。 The contact member 204 is formed of a conductive material such as a metal. One end of the contact member 204 serves as a first contact terminal 204a of the socket contact 210, and the other end serves as a third contact terminal 204b of the screwless terminal block 220. It is preferable that the contact member 204 be made of a spring copper material (for example, phosphor bronze) having high electrical conductivity as well as having spring properties. The leaf spring member 205 is formed of a material having a strong spring property (for example, SUS), one end of which serves as the second contact terminal 205a of the socket contact 210, and the other end of which serves as the fourth contact terminal 205c of the screwless terminal block 220. Becomes A hook portion 205b is formed at the tip of the second contact terminal 205a of the leaf spring member 205.
　ソケット部品２００におけるソケットコンタクト２１０は、接点部材２０４の第１接点端子２０４ａと板バネ部材２０５の第２接点端子２０５ａとが対向配置されることによって構成される。すなわち、ソケット部品２００をプラグ部品１００に嵌合させ、ソケットコンタクト２１０における第１接点端子２０４ａと第２接点端子２０５ａとの間でピンコンタクト１０２が狭持されることにより、コネクタ１０の接続がなされる。尚、ソケットコンタクト２１０において、第２接点端子２０５ａは、板バネ部材２０５の弾性力により第１接点端子２０４ａに圧接するように付勢されている。また、第１接点端子２０４ａも板バネとされて、第２接点端子２０５ａに圧接するように付勢されていてもよい。 The socket contact 210 of the socket component 200 is configured by disposing the first contact terminal 204a of the contact member 204 and the second contact terminal 205a of the leaf spring member 205 to face each other. In other words, the connector 10 is connected by fitting the socket component 200 to the plug component 100 and pinching the pin contact 102 between the first contact terminal 204a and the second contact terminal 205a of the socket contact 210. You. In the socket contact 210, the second contact terminal 205a is urged to press against the first contact terminal 204a by the elastic force of the leaf spring member 205. Further, the first contact terminal 204a may also be a leaf spring, and may be urged to press against the second contact terminal 205a.
　ソケット部品２００におけるスクリューレス端子台２２０は、接点部材２０４の第３接点端子２０４ｂと板バネ部材２０５の第４接点端子２０５ｃとが対向配置されることによって構成される。また、第４接点端子２０５ｃは、板バネ部材２０５の弾性力により第３接点端子２０４ｂに圧接するように付勢されている。また、ソケットハウジング２０２には、配線挿入孔２０２ａおよび結線解除補助孔２０２ｂが設けられている。配線挿入孔２０２ａは、スクリューレス端子台２２０に結線される配線（被覆を剥かれた電線や棒端子）を挿入する孔であり、配線挿入孔２０２ａから挿入した配線を第３接点端子２０４ｂと第４接点端子２０５ｃとの間で狭持することで結線される。結線解除補助孔２０２ｂは、結線の解除を行う時などに、ドライバーなどの工具を差し込み、第４接点端子２０５ｃを第３接点端子２０４ｂから離間させるための孔である。 The screwless terminal block 220 of the socket component 200 is configured by disposing the third contact terminal 204b of the contact member 204 and the fourth contact terminal 205c of the leaf spring member 205 to face each other. Further, the fourth contact terminal 205c is urged to press against the third contact terminal 204b by the elastic force of the leaf spring member 205. The socket housing 202 is provided with a wire insertion hole 202a and a connection release assisting hole 202b. The wire insertion hole 202a is a hole into which a wire (an uncoated wire or a bar terminal) connected to the screwless terminal block 220 is inserted. The wire inserted from the wire insertion hole 202a is connected to the third contact terminal 204b and the third contact terminal 204b. It is connected by holding it between the four contact terminals 205c. The connection release assist hole 202b is a hole for inserting a tool such as a screwdriver to separate the fourth contact terminal 205c from the third contact terminal 204b when disconnecting the connection.
　また、上記説明では、板バネ部材２０５をＳＵＳとした場合を例示しているが、ソケットコンタクト２１０とスクリューレス端子台２２０との間の電気導通は接点部材２０４によって得られるため、板バネ部材２０５は導電性を有していなくてもよい。但し、板バネ部材２０５が導電性を有している場合には、接点部材２０４だけでなく、板バネ部材２０５によってもソケットコンタクト２１０とスクリューレス端子台２２０との間の電気導通が得られるため、ソケット部品２００における電気特性が向上し、好ましい。 In the above description, the case where the leaf spring member 205 is SUS is illustrated. However, since electrical conduction between the socket contact 210 and the screwless terminal block 220 is obtained by the contact member 204, the leaf spring member 205 Need not have conductivity. However, when the leaf spring member 205 has conductivity, electric conduction between the socket contact 210 and the screwless terminal block 220 can be obtained not only by the contact member 204 but also by the leaf spring member 205. This is preferable because the electrical characteristics of the socket component 200 are improved.
　ロックレバー２３０は、ソケット本体２０１の側面に設けられた支軸２０１ａ（図１参照）に係合溝２３１（図１参照）を係合させることで支軸２０１ａの周りで回動可能にソケット本体２０１に取り付けられる。ロックレバー２３０の一端部（図２における上方の端部）は、ユーザが力を加えるための操作部２３２となっている。ロックレバー２３０の他端部（図２における下方の端部）には係合突起部２３３が形成されており、係合突起部２３３は板バネ部材２０５のフック部２０５ｂに係合接続されている。このため、ロックレバー２３０は、板バネ部材２０５の弾性力により、図２に示す矢印Ａ１方向に付勢されている。 The lock lever 230 is rotatable around the support shaft 201a by engaging an engagement groove 231 (see FIG. 1) with a support shaft 201a (see FIG. 1) provided on a side surface of the socket body 201. It is attached to 201. One end (upper end in FIG. 2) of the lock lever 230 is an operation unit 232 for applying a force by the user. An engagement protrusion 233 is formed at the other end (the lower end in FIG. 2) of the lock lever 230, and the engagement protrusion 233 is engaged and connected to the hook 205 b of the leaf spring member 205. . Therefore, the lock lever 230 is urged in the direction of arrow A1 shown in FIG. 2 by the elastic force of the leaf spring member 205.
　続いて、ソケット部品２００をプラグ部品１００に差し込んで嵌合させる時の嵌合動作について、図３（ａ）～（ｃ）を参照して説明する。図３（ａ）は、嵌合前のソケット部品２００とプラグ部品１００とが分離した状態を示している。 Next, the fitting operation when the socket component 200 is inserted into the plug component 100 and fitted will be described with reference to FIGS. 3 (a) to 3 (c). FIG. 3A shows a state where the socket component 200 and the plug component 100 have been separated before fitting.
　図３（ｂ）は、嵌合動作途中の状態を示しており、ユーザはソケット本体２０１とロックレバー２３０の操作部２３２とを挟むようにしてソケット部品２００を持つ。この時、操作部２３２に作用する力により、ロックレバー２３０は矢印Ａ２方向に回動する。ロックレバー２３０が矢印Ａ２方向に回動することで、板バネ部材２０５のフック部２０５ｂが係合突起部２３３に引っ張られ、接点部材２０４の第１接点端子２０４ａと板バネ部材２０５の第２接点端子２０５ａとの間が離間する。そして、第１接点端子２０４ａと第２接点端子２０５ａとの間が離間した状態で、ソケット部品２００をプラグ部品１００に差し込むことで、ピンコンタクト１０２と第１接点端子２０４ａおよび第２接点端子２０５ａとの間に生じる摩擦力を無くす（もしくは大幅に低減する）ことができる。すなわち、ソケット部品２００を極めて小さい挿抜力にてプラグ部品１００に差し込むことができる。 FIG. 3B shows a state in the middle of the fitting operation, and the user holds the socket component 200 so as to sandwich the socket body 201 and the operation part 232 of the lock lever 230. At this time, the lock lever 230 rotates in the direction of arrow A2 due to the force acting on the operation unit 232. When the lock lever 230 rotates in the direction of arrow A2, the hook portion 205b of the leaf spring member 205 is pulled by the engagement protrusion 233, and the first contact terminal 204a of the contact member 204 and the second contact point of the leaf spring member 205. The terminal 205a is separated. Then, by inserting the socket component 200 into the plug component 100 in a state where the first contact terminal 204a and the second contact terminal 205a are separated from each other, the pin contact 102, the first contact terminal 204a, and the second contact terminal 205a are connected. It is possible to eliminate (or greatly reduce) the frictional force generated during the operation. That is, the socket component 200 can be inserted into the plug component 100 with an extremely small insertion / extraction force.
　ソケット部品２００をプラグ部品１００に差し込んだ後は、ユーザが手を離すことで、図３（ｃ）に示すように、ロックレバー２３０は板バネ部材２０５の弾性力によって矢印Ａ１方向に回動する。これにより、ピンコンタクト１０２は第１接点端子２０４ａおよび第２接点端子２０５ａによって挟持される。この時、板バネ部材２０５の弾性力に加え、接点部材２０４の弾性力も合わさって、ピンコンタクト１０２と接点部材２０４との間に十分な接触圧力が生じて、ピンコンタクト１０２と接点部材２０４との間の適切な電気接続が得られる。また、ピンコンタクト１０２を第１接点端子２０４ａと第２接点端子２０５ａとの間で適切に保持することもできる。尚、ソケット部品２００をプラグ部品１００から抜き取る時は、差し込み時と逆の動作を行えばよい。 After inserting the socket component 200 into the plug component 100, the user releases his / her hand, and as shown in FIG. 3C, the lock lever 230 rotates in the direction of arrow A1 by the elastic force of the leaf spring member 205. . As a result, the pin contact 102 is held between the first contact terminal 204a and the second contact terminal 205a. At this time, in addition to the elastic force of the leaf spring member 205 and the elastic force of the contact member 204, a sufficient contact pressure is generated between the pin contact 102 and the contact member 204, and the contact force between the pin contact 102 and the contact member 204 is increased. A proper electrical connection between them is obtained. Further, the pin contact 102 can be appropriately held between the first contact terminal 204a and the second contact terminal 205a. Note that when the socket component 200 is removed from the plug component 100, the operation may be performed in the reverse order of the insertion.
　ロックレバー２３０に関しては、支軸２０１ａから操作部２３２の端部までの距離が、支軸２０１ａから係合突起部２３３の端部までの距離よりも長くなるように設定されることが好ましい。この場合、てこの原理により、操作部２３２の操作力を小さくして操作性を向上させながら、ピンコンタクト１０２に対する圧接力を大きくすることができる。 Regarding the lock lever 230, it is preferable that the distance from the support shaft 201a to the end of the operation portion 232 is set to be longer than the distance from the support shaft 201a to the end of the engagement protrusion 233. In this case, according to the leverage principle, the pressing force on the pin contact 102 can be increased while the operability is improved by reducing the operating force of the operating section 232.
　以上のように、本実施の形態に係るソケット部品２００は、板バネ部材２０５の一端部にスクリューレス端子台２２０において板バネ機能を有する第４接点端子２０５ｃを形成すると共に、板バネ部材２０５の他端部をソケットコンタクト２１０側に延長して、該他端部にソケットコンタクト２１０の第２接点端子２０５ａを形成している。これにより、スクリューレス端子台２２０で必要となる板バネ部材２０５を、ソケットコンタクト２１０側でも接点端子間の接触圧力の付与に有効に利用でき、部材点数を増やすことなく、高い接触信頼性が得らえるソケットコンタクト２１０を有するコネクタ１０を得ることができる。すなわち、高いバネ性を有する板バネ部材２０５によって、接点端子間の接触圧力を高くすることが容易であり、ソケットコンタクト２１０において高い接触信頼性を確保することができる。 As described above, the socket component 200 according to the present embodiment forms the fourth contact terminal 205c having the leaf spring function in the screwless terminal block 220 at one end of the leaf spring member 205, and The other end is extended to the socket contact 210 side, and the second contact terminal 205a of the socket contact 210 is formed at the other end. Thus, the leaf spring member 205 required for the screwless terminal block 220 can be effectively used to apply the contact pressure between the contact terminals even on the socket contact 210 side, and high contact reliability can be obtained without increasing the number of members. The connector 10 having the socket contacts 210 can be obtained. That is, it is easy to increase the contact pressure between the contact terminals by the leaf spring member 205 having a high spring property, and it is possible to secure high contact reliability in the socket contact 210.
　尚、一般にソケットコンタクトにおける接点端子間の接触圧力を高くした場合、ソケットコンタクトとピンコンタクトとの嵌合が固くなり、コネクタの抜き差しが困難となる。これに対し、本実施の形態に係るコネクタ１０では、ソケットコンタクト２１０とピンコンタクト１０２との挿抜時に、ロックレバー２３０を操作することで接点端子間の接触圧力を低減させることができ、コネクタ１０の抜き差しも容易となる。 In general, when the contact pressure between the contact terminals of the socket contact is increased, the fitting between the socket contact and the pin contact becomes firm, and it becomes difficult to insert and remove the connector. On the other hand, in the connector 10 according to the present embodiment, when the socket contact 210 and the pin contact 102 are inserted and removed, the contact pressure between the contact terminals can be reduced by operating the lock lever 230. It becomes easy to insert and remove.
　また、ロックレバー２３０およびプラグ部品１００には、ソケット部品２００がプラグ部品１００に嵌合している状態でソケット部品２００の抜け落ちを防止するための保持機構が設けられていてもよい。図４は、そのような保持機構の一構成例を示す断面図である。尚、図４に示す断面は、図２，３とは異なる箇所での断面であり、プラグ用ハウジング１０１に形成されている第１係合部１０３（図１参照）の形成箇所に対応する断面である。 The lock lever 230 and the plug component 100 may be provided with a holding mechanism for preventing the socket component 200 from falling off when the socket component 200 is fitted to the plug component 100. FIG. 4 is a cross-sectional view showing one configuration example of such a holding mechanism. The cross section shown in FIG. 4 is a cross section at a location different from those in FIGS. It is.
　図４に示すように、プラグ用ハウジング１０１におけるロックレバー２３０との対向面には第１係合部１０３が形成されている。一方、ロックレバー２３０には、支軸２０１ａに対する他端部（係合突起部２３３と同一側の端部）において、プラグ用ハウジング１０１との対向面に第２係合部２３４が形成されている。そして、ソケット部品２００がプラグ部品１００に嵌合されユーザが手を離した状態（図３（ｃ）に対応する状態）では、第１係合部１０３と第２係合部２３４とが係合することによって、ソケット部品２００の抜け落ちが防止できる。尚、ソケット部品２００をプラグ部品１００から抜き取る時は、ロックレバー２３０の操作により、第１係合部１０３と第２係合部２３４との係合が容易に解除できる。 に は As shown in FIG. 4, a first engaging portion 103 is formed on a surface of the plug housing 101 facing the lock lever 230. On the other hand, the lock lever 230 has a second engagement portion 234 formed at the other end (the end on the same side as the engagement protrusion 233) with respect to the support shaft 201a, on the surface facing the plug housing 101. . In a state where the socket component 200 is fitted to the plug component 100 and the user releases his / her hand (a state corresponding to FIG. 3C), the first engagement portion 103 and the second engagement portion 234 are engaged. By doing so, it is possible to prevent the socket component 200 from falling off. When the socket component 200 is removed from the plug component 100, the engagement between the first engagement portion 103 and the second engagement portion 234 can be easily released by operating the lock lever 230.
　また、上記説明では、コネクタ１０がソケット部品２００とプラグ部品１００とによって構成され、プラグ部品１００はプラグ用ハウジング１０１にピンコンタクト１０２を収容した構成となっている。しかしながら、ソケット部品２００の使用形態は、このようなプラグ部品１００と嵌合される形態に限定されるものではなく、ピンコンタクト１０２のみに対してソケットコンタクト２１０を嵌合させて使用することも可能である。 In the above description, the connector 10 includes the socket component 200 and the plug component 100, and the plug component 100 has a configuration in which the pin contact 102 is housed in the plug housing 101. However, the usage mode of the socket component 200 is not limited to the mode in which the socket component 200 is fitted to the plug component 100, and the socket component 210 can be used by fitting the socket contact 210 only to the pin contact 102. It is.
　さらに、図５に本開示に係るコネクタ１０の変形例を示す。図５に示すコネクタ１０では、ソケットコンタクト２１０側において、同一の接点部材２０４に第１接点端子２０４ａと第２接点端子２０４ｃとが形成されている。そして、板バネ部材２０５の他端部は、第２接点端子２０４ｃに対して外側からバネ圧を付与する構成となっている。 FIG. 5 shows a modification of the connector 10 according to the present disclosure. In the connector 10 shown in FIG. 5, a first contact terminal 204a and a second contact terminal 204c are formed on the same contact member 204 on the socket contact 210 side. The other end of the leaf spring member 205 applies a spring pressure to the second contact terminal 204c from outside.
　この場合、接点部材２０４のみによっても、第１接点端子２０４ａと第２接点端子２０４ｃとの間に接触圧力は付与されるが、接点部材２０４のみでの接触圧力は低く設定されるものであり、板バネ部材２０５からのバネ圧が付与されることで十分な接触圧力が得られるものである。図５に示す構成においては、ロックレバー２３０を操作して、板バネ部材２０５の他端部を第２接点端子２０４ｃから離間させると、板バネ部材２０５によるバネ圧の付与が解除され、接点部材２０４のみの接触圧力となるため、ソケットコンタクト２１０側の接点端子間の接触圧力を低減することができる。これにより、ピンコンタクト１０２とソケットコンタクト２１０との抜き差しが行いやすいコネクタ１０を得ることができる。図５に示す構成では、ピンコンタクト１０２と直接接触する第１接点端子２０４ａおよび第２接点端子２０４ｃを共に電気伝導性の高いバネ用銅材とすることができ、ソケットコンタクト２１０において、より高い接触信頼性が得らえる。 In this case, the contact pressure is applied between the first contact terminal 204a and the second contact terminal 204c only by the contact member 204, but the contact pressure only by the contact member 204 is set low. By applying the spring pressure from the leaf spring member 205, a sufficient contact pressure can be obtained. In the configuration shown in FIG. 5, when the lock lever 230 is operated to separate the other end of the leaf spring member 205 from the second contact terminal 204c, the application of the spring pressure by the leaf spring member 205 is released, and the contact member Since the contact pressure is only at 204, the contact pressure between the contact terminals on the socket contact 210 side can be reduced. Thus, the connector 10 in which the pin contact 102 and the socket contact 210 can be easily inserted and removed can be obtained. In the configuration shown in FIG. 5, both the first contact terminal 204a and the second contact terminal 204c that are in direct contact with the pin contact 102 can be made of a copper material for a spring having high electrical conductivity, and the socket contact 210 has a higher contact. Reliability can be obtained.
