Description

本発明は、開閉可能な加圧部材を操作することによって接続対象物の接続を得るタイプのコネクタに関する。 The present invention relates to a connector of a type that obtains connection of a connection object by operating a pressure member that can be opened and closed.

例えば液晶テレビの内部には、ＦＰＣやＦＦＣと呼ばれる平型導体が多用されている。この平型導体のような接続対象物の接続には、開閉可能な加圧部材を備えたコネクタが用いられることがある。この種のコネクタは特許文献１に「平型導体用電気コネクタ」と題して開示されている。 For example, flat conductors called FPC and FFC are frequently used in liquid crystal televisions. A connector provided with a pressure member that can be opened and closed may be used for connection of a connection object such as a flat conductor. This type of connector is disclosed in Patent Document 1 under the title “Electric connector for a flat conductor”.

図１２、図１３Ａ、及び図１３Ｂを用いて、特許文献１に開示されているコネクタを簡単に説明する。 The connector disclosed in Patent Literature 1 will be briefly described with reference to FIGS. 12, 13A, and 13B.

図１２から図１３Ｂに示すコネクタは、絶縁性のハウジング１と、ハウジング１に保持された互いに離間する第１及び第２の端子２、３と、第１及び第２の端子２、３に平型導体Ｆを圧接させるための加圧部材４とを含んでいる。加圧部材４は第１及び第２の端子２、３に対応した溝部４ａ、４ｂを有し、これらの溝部４ａ、４ｂに軸部４ｃ、４ｄがそれぞれ形成されている。一方の軸部４ｃは第１の端子２の回動支持部２ａに回動可能に支持される。他方の軸部４ｄは、第２の端子３の二つの規制案内部３ａの間に配置される。こうして、加圧部材４は軸部４ｃ、４ｄを支点として回動操作を可能にされている。 The connector shown in FIG. 12 to FIG. 13B is flat on the insulating housing 1, the first and second terminals 2, 3 that are held apart from each other, and the first and second terminals 2, 3. And a pressing member 4 for press-contacting the mold conductor F. The pressing member 4 has groove portions 4a and 4b corresponding to the first and second terminals 2 and 3, and shaft portions 4c and 4d are formed in these groove portions 4a and 4b, respectively. One shaft portion 4 c is rotatably supported by the rotation support portion 2 a of the first terminal 2. The other shaft portion 4 d is disposed between the two regulation guide portions 3 a of the second terminal 3. Thus, the pressing member 4 can be rotated about the shafts 4c and 4d as fulcrums.

接続に際し、加圧部材開状態で平型導体Ｆをハウジング１の開口部１ａに挿入し、第１及び第２の端子２、３の接触部２ｂ、３ｂに対応するように位置付ける。しかる後に、加圧部材４を操作して加圧部材閉状態を得ることにより、平型導体Ｆを接触部２ｂ、３ｂに圧接させる。 At the time of connection, the flat conductor F is inserted into the opening 1a of the housing 1 in a state where the pressure member is open, and is positioned so as to correspond to the contact portions 2b and 3b of the first and second terminals 2 and 3. Thereafter, the flat conductor F is brought into pressure contact with the contact portions 2b and 3b by operating the pressure member 4 to obtain the pressure member closed state.

また、加圧部材４を反対向きに操作して加圧部材開状態を得ると、平型導体Ｆをハウジング１の開口部１ａから容易に離脱させることが可能になる。 Further, when the pressure member 4 is operated in the opposite direction to obtain the pressure member open state, the flat conductor F can be easily detached from the opening 1 a of the housing 1.

特許第４３９０８２１号公報Japanese Patent No. 4390821

図１２から図１３Ｂのコネクタにおいて、平型導体Ｆをハウジング１の開口部１ａに挿入していない接続対象物未装着時に、加圧部材開状態にすることがある。この状態にあるときに、加圧部材４に負荷が掛かると、加圧部材４が外れてしまうことがある。また、接続対象物未装着時に、加圧部材閉状態にすることもある。この状態にあるときにも、加圧部材４に負荷が掛かると、同様に加圧部材４が外れてしまうことがある。 In the connector shown in FIGS. 12 to 13B, when the flat object F is not inserted into the opening 1a of the housing 1 and the connection object is not attached, the pressure member may be opened. When the pressure member 4 is under load in this state, the pressure member 4 may come off. Further, the pressure member may be closed when the connection object is not attached. Even in this state, if a load is applied to the pressure member 4, the pressure member 4 may be similarly removed.

具体的には、コネクタ検査時などのように接続対象物未装着時に加圧部材４を操作する所謂空操作を行うとき、加圧部材４の中央付近が弓形に撓んで、軸部４ｃが第１の端子２から離脱し、加圧部材４が外れる虞がある。 Specifically, when performing a so-called empty operation in which the pressure member 4 is operated when the connection object is not attached, such as during connector inspection, the vicinity of the center of the pressure member 4 is bent into an arcuate shape, and the shaft portion 4c is 1 may be detached from the terminal 2 and the pressure member 4 may come off.

加圧部材４が外れやすい原因は、第１の端子２の回動支持部２ａのみによって加圧部材４を回動可能に支持し、第２の端子３が加圧部材４の外れ防止になんら寄与していないことにある。 The reason why the pressurizing member 4 is easily detached is that the pressurizing member 4 is rotatably supported only by the rotation support portion 2 a of the first terminal 2, and the second terminal 3 prevents the pressurizing member 4 from coming off. It does not contribute.

それ故に本発明の課題は、開閉操作される加圧部材の外れ防止効果を高めたコネクタを提供することにある。 Therefore, an object of the present invention is to provide a connector with an enhanced effect of preventing the pressure member that is opened and closed from coming off.

まず図１から図４を参照して、本発明の実施形態に係るコネクタの全体構造について説明する。 First, an overall structure of a connector according to an embodiment of the present invention will be described with reference to FIGS.

図示のコネクタ１０は例えばプリント基板（図示せず）などに面実装されるのに適したものであり、第１の方向Ａ１に細長くのびた形状を有するハウジング１１を含んでいる。ハウジング１１は、絶縁性の合成樹脂から作られたものである。ハウジング１１の第１の方向Ａ１における両端の各々には金属製のホールドダウン１２が備えられている。ホールドダウン１２は、実装対象となるプリント基板などに半田付けされる半田付け部１２ａを有している。 The illustrated connector 10 is suitable for surface mounting on a printed circuit board (not shown), for example, and includes a housing 11 having an elongated shape in the first direction A1. The housing 11 is made of an insulating synthetic resin. A metal hold-down 12 is provided at each of both ends of the housing 11 in the first direction A1. The holddown 12 has a soldering part 12a to be soldered to a printed circuit board or the like to be mounted.

ハウジング１１には、導電性の端子である多数のコンタクトが第１の方向Ａ１に互いに一定間隔をおいて平行に配設されかつ固定保持されている。これらのコンタクトは、２種のコンタクト、即ち、第１のコンタクト１３と第２のコンタクト１４とを含んでいる。本実施形態では、第１のコンタクト１３の２本と第２のコンタクトの１本とを第１の方向Ａ１に交互に並べた配列形態を採っているが、これに限らず、他の様々な配列形態を採ることもできる。 In the housing 11, a large number of contacts, which are conductive terminals, are disposed in parallel in the first direction A1 at a predetermined interval and fixedly held.

In this way, the pressing member 15 is locked by the second contact 14 in the opening direction.

今、図７Ａ及び図７Ｂに示すように接続対象物が未装着でかつ加圧部材１５が開状態にあるときに、加圧部材１５に第２の方向Ａ２で前方への外力が働いたと仮定する。この場合、加圧部材１５は可撓材料より作られているので、第１の方向Ａ１（図１参照）における中間部が弓形に撓みつつ、第２の方向Ａ２における前方へ動く。しかし、Ｕ字状端部１６の凹部１６ａの側面を規定する壁部１６ｂにカム１５ｃが係合することに加え、図７Ｃに示すように、加圧部材１５の係止部１５ｄがＴ字状端部１７の突起１７ｂに係合することになるので、加圧部材１５が第１及び第２のコンタクト１３、１４から離脱することは防止される。このように、凹部１６ａの側面を規定する壁部１６ｂと突起１７ｂとの両方によって、カム１５ｃが第１のコンタクト１３から外れるのを防止する。したがって、図７Ａ及び図７Ｂに示す状態にあるときにも、加圧部材１５の離脱がより確実に阻止される。 7A and 7B, it is assumed that a forward external force is applied to the pressure member 15 in the second direction A2 when the connection object is not attached and the pressure member 15 is in the open state. To do. In this case, since the pressing member 15 is made of a flexible material, the intermediate portion in the first direction A1 (see FIG. 1) is bent in an arcuate shape and moves forward in the second direction A2. However, in addition to the cam 15c engaging with the wall 16b that defines the side surface of the recess 16a of the U-shaped end 16, the locking portion 15d of the pressure member 15 is T-shaped as shown in FIG. Since it engages with the protrusion 17 b of the end portion 17, the pressing member 15 is prevented from being detached from the first and second contacts 13 and 14. In this way, the cam 15c is prevented from being detached from the first contact 13 by both the wall portion 16b and the projection 17b that define the side surface of the recess 16a. Therefore, even in the state shown in FIG. 7A and FIG. 7B, the detachment of the pressing member 15 is more reliably prevented.

加圧部材１５を図８Ａ及び図８Ｂに示す位置まで図中で反時計回りに回動させると、加圧部材１５の係止部１５ｄが第２のコンタクト１４の上腕部１４ｂから離間する。加圧部材１５を図９Ａ及び図９Ｂに示す位置まで図中で反時計回りにさらに回動させると、加圧部材１５の係止部１５ｄが第２のコンタクト１４の突起１７ｂの上方を通過する。 When the pressing member 15 is rotated counterclockwise in the drawing to the position shown in FIGS. 8A and 8B, the locking portion 15 d of the pressing member 15 is separated from the upper arm portion 14 b of the second contact 14. When the pressing member 15 is further rotated counterclockwise in the drawing to the position shown in FIGS. 9A and 9B, the locking portion 15 d of the pressing member 15 passes above the protrusion 17 b of the second contact 14. .

加圧部材１５を図１０Ａ及び図１０Ｂに示す位置まで図中で反時計回りにさらに回動させると、加圧部材１５の係止部１５ｄが第２のコンタクト１４の突起１７ｂの反対側、即ち、上腕部１４ｂの自由端側で直線部１７ａに当接する。したがって、加圧部材１５は第２のコンタクト１４により閉方向への動きを係止される。 When the pressing member 15 is further rotated counterclockwise in the drawing to the position shown in FIGS. 10A and 10B, the locking portion 15d of the pressing member 15 is opposite to the protrusion 17b of the second contact 14, that is, Then, it comes into contact with the linear portion 17a on the free end side of the upper arm portion 14b. Therefore, the pressing member 15 is locked by the second contact 14 in the closing direction.

今、図１０Ａ及び図１０Ｂに示すように接続対象物が未装着でかつ加圧部材１５が閉状態にあるときに、加圧部材１５に第２の方向Ａ２で後方への外力が働いたと仮定する。この場合、加圧部材１５は可撓材料より作られているので、第１の方向Ａ１（図１参照）における中間部が弓形に撓みつつ、第２の方向Ａ２における後方へ動く。しかし、Ｕ字状端部１６の凹部１６ａの側面を規定する壁部１６ｃにカム１５ｃが係合することに加え、図１０Ｃに示すように、加圧部材１５の係止部１５ｄがＴ字状端部１７の突起１７ｂに係合することになるので、加圧部材１５が第１及び第２のコンタクト１３、１４から離脱することは防止される。このように、凹部１６ａの側面を規定する壁部１６ｃと突起１７ｂとの両方によって、カム１５ｃが第１のコンタクト１３から外れるのを防止する。したがって、図１０Ａ及び図１０Ｂに示す状態にあるときに加圧部材１５の離脱がより確実に阻止される。 10A and 10B, it is assumed that an external force is applied to the pressure member 15 in the second direction A2 when the object to be connected is not attached and the pressure member 15 is in the closed state. To do. In this case, since the pressing member 15 is made of a flexible material, the intermediate portion in the first direction A1 (see FIG. 1) bends in an arcuate shape and moves backward in the second direction A2. However, in addition to the cam 15c engaging with the wall portion 16c defining the side surface of the concave portion 16a of the U-shaped end portion 16, as shown in FIG. 10C, the locking portion 15d of the pressing member 15 is T -shaped. Since it engages with the protrusion 17 b of the end portion 17, the pressing member 15 is prevented from being detached from the first and second contacts 13 and 14. Thus, the cam 15c is prevented from being detached from the first contact 13 by both the wall portion 16c defining the side surface of the concave portion 16a and the projection 17b. Therefore, when the pressure member 15 is in the state shown in FIGS. 10A and 10B, the detachment of the pressure member 15 is more reliably prevented.

上述したように、コネクタ１０は２種類のコンタクトで加圧部材１５を挟持すると共に、加圧部材１５に負荷が掛った際に、加圧部材１５が弓形に撓んでコンタクトから外れることを防止するストッパー構造を有している。したがって、接続対象物未挿入時において加圧部材１５の操作によるコンタクトからの加圧部材１５の外れや加圧部材１５に負荷を掛けた際のコンタクトからの加圧部材１５の外れを防ぐことができる。このため、例えばコネクタ検査時などに加圧部材１５を接続対象物の未装着状態で開閉する所謂空操作が行われても、加圧部材１５の離脱が生じる虞は少ない。 As described above, the connector 10 sandwiches the pressure member 15 with two types of contacts, and prevents the pressure member 15 from bending out of contact with the pressure member 15 when the pressure member 15 is loaded. It has a stopper structure. Accordingly, it is possible to prevent the pressure member 15 from being detached from the contact by operating the pressure member 15 when the connection object is not inserted, or from the contact when the pressure member 15 is loaded. it can. For this reason, for example, even when a so-called empty operation for opening and closing the pressure member 15 without connecting the object to be connected is performed at the time of connector inspection or the like, there is little possibility that the pressure member 15 is detached.

図１１Ａ及び図１１Ｂに、コネクタ１０にＦＰＣやＦＦＣと呼ばれる平型導体よりなる接続対象物１８を接続した状態を示す。このとき、加圧部材１５は閉状態にある。 FIG. 11A and FIG. 11B show a state in which a connection object 18 made of a flat conductor called FPC or FFC is connected to the connector 10. At this time, the pressure member 15 is in a closed state.

図１１Ａに示すように、加圧部材１５のカム１５ｃが第１のコンタクト１３の上腕部１３ｂを持ち上げるのに伴い、その反力により加圧部材１５が接続対象物１８を下方に押圧する。したがって、接続対象物１８の下面の第１の接点部１８ａが第１のコンタクト１３の接触部１３ｄに圧接される。 As shown in FIG. 11A, as the cam 15c of the pressing member 15 lifts the upper arm portion 13b of the first contact 13, the pressing member 15 presses the connection object 18 downward by the reaction force. Accordingly, the first contact portion 18 a on the lower surface of the connection target 18 is pressed against the contact portion 13 d of the first contact 13.

また図１１Ｂに示すように、加圧部材１５によって下方に押圧された接続対象物１８の下面の第２の接点部１８ｂは第２のコンタクト１４の接触部１４ｄにも圧接される。こうして、接続対象物１８は第１及び第２のコンタクト１３、１４に電気的に接続される。なお、この状態においては、加圧部材１５の係止部１５ｄは第２のコンタクト１４の上腕部１４ｂから離間する。 As shown in FIG. 11B, the second contact portion 18 b on the lower surface of the connection object 18 pressed downward by the pressure member 15 is also pressed against the contact portion 14 d of the second contact 14. Thus, the connection object 18 is electrically connected to the first and second contacts 13 and 14. In this state, the locking portion 15 d of the pressure member 15 is separated from the upper arm portion 14 b of the second contact 14.
