Description

  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.

  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”.

  The connector disclosed in Patent Literature 1 will be briefly described with reference to FIGS. 12, 13A, and 13B.

  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.

  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.

  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.

The pressure member 15 extends linearly along the housing 11 in the first direction A1. 1 and 4 show the open state of the pressure member 15.

  The pressing member 15 will be described with reference to FIGS. 6A and 6B together with FIG.

  The pressurizing member 15 is an elongated plate made of a flexible material such as nylon-based plastic, and therefore can be slightly bent in the first direction A1. In particular, it will be easily understood that the pressure member 15 is easily bent in the thickness direction. Further, the pressing member 15 allows some bending in the plate width direction.

  The pressing member 15 has a first groove portion 15a (FIG. 6A) and a second groove portion 15b (FIG. 6B) which correspond to the first contact 13 and the second contact 14 on a one-to-one basis. That is, FIG. 6A is a cross-sectional view cut at a portion of the first groove 15a, and FIG. 6B is a cross-sectional view cut at a portion of the second groove 15b. The pressure member 15 includes a cam 15c serving as a shaft portion provided in the first groove portion 15a and a locking portion 15d provided in the second groove portion 15b.

The locking portion 15d protrudes from the bottom surface of the second groove portion 15b and is integrally formed on the opposing wall surface that defines the second groove portion 15b. Note that the shapes and dimensions of the cam 15c and the locking portion 15d will become apparent from the description of the operation of the connector described later.

  The description of the overall structure of the connector 10 will be continued with reference to FIGS. 7A and 7B. 7A and 7B show an open state of the pressure member 15 with no connection target attached.

  The housing 11 has an insertion port 11a at the front end (left end in the drawing) in the second direction A2 orthogonal to the first direction A1 for inserting the connection object, and an arrangement region 11b following the insertion port 11a. ing. As will be described in detail later, the connection object is connected to the connector 10 by operating the pressing member 15 in a closed state in a state where the end portion is disposed in the arrangement region 11b through the insertion port 11a. Is done.

  As shown in FIG. 7A, the first contact 13 has a fixed portion 13a fixed to the housing 11, and extends forward (leftward in the drawing) from the fixed portion 13a in the second direction A2 above and below the arrangement region 11b. It has the upper arm part 13b and the lower arm part 13c which are located in both sides. The front ends of the upper arm portion 13b and the lower arm portion 13c are free ends.

  At the end of the upper arm 13b of the first contact 13, that is, in the vicinity of the free end, a rotation guide end (hereinafter referred to as “U-shaped end”) for guiding the rotation of the cam 15c of the pressure member 15 is provided. 16) is provided. The U-shaped end portion 16 has a recessed portion 16a that faces downward in a third direction A3 orthogonal to the first and second directions A1 and A2 and receives the cam 15c in a rotatable manner.

  A contact portion 13d for obtaining electrical contact with the connection object is formed at the end of the lower arm portion 13c of the first contact 13, that is, in the vicinity of the free end. The contact portion 13d has a shape that slightly protrudes upward at a position substantially opposed to the recess 16a.

  As shown in FIG. 7B, the second contact 14 includes a fixed portion 14a fixed to the housing 11, and extends forward (leftward in the drawing) in the second direction A2 from the fixed portion 14a. It has the upper arm part 14b and the lower arm part 14c which are located in both sides. The front ends of the upper arm portion 14b and the lower arm portion 14c are free ends.

  A stopper end portion (hereinafter referred to as “T-shaped end portion”) 17 serving as a stopper of the pressure member 15 is formed at the end portion of the upper arm portion 14 b of the second contact 14, that is, in the vicinity of the free end. Yes. The T-shaped end portion 17 is provided at a position facing the locking portion 15d. The straight portion 17a is located on the opposite side of the U-shaped end portion 16 with respect to the cam 15c. And a protrusion 17b protruding upward in the third direction A3.

  In the state shown in FIGS. 7A and 7B, the locking portion 15d of the pressing member 15 is one side as viewed from the protrusion 17b of the straight portion 17a of the second contact 14, specifically, the straight portion on the fixed portion 14a side. 17a. In this way, the pressing member 15 is locked by the second contact 14 in the opening direction.

  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.

  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. .

  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.

  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 16c that defines the side surface of the recess 16a of the U-shaped end 16, the locking portion 15d of the pressure member 15 has a T-shape as shown in FIG. 10C. 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.

  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.

  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.

  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.

  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.
