Description

Connector

technical field

The present invention relates to a connector of a type in which a connection object is connected by operating an openable and closable pressing member.

Background technique

For example, in LCD TVs, flat conductors called FPC or FFC are often used. A connector including an openable and closable pressurizing member may be used for connecting objects to be connected such as flat conductors. Such a connector is disclosed in Japanese Patent No. 4390821 (Patent Document 1) under the title "Electrical Connector for Flat Conductor".

The connector disclosed in Patent Document 1 will be briefly described using FIGS. 12 , 13A, and 13B.

The connector shown in Fig. 12 to Fig. 13B comprises: an insulative housing 1; first and second terminals 2, 3 which are kept separated from each other by the housing 1; for connecting the flat conductor F to the first and second The pressurizing member 4 with which the two terminals 2 and 3 are in pressure contact. The pressurizing member 4 has groove portions 4a, 4b corresponding to the first and second terminals 2, 3, and shaft portions 4c, 4d are formed in these groove portions 4a, 4b, respectively. One shaft portion 4c is rotatably supported by the rotation support portion 2a of the first terminal 2 . The other shaft portion 4d is disposed between the two regulation guide portions 3a of the second terminal 3 . In this way, the pressurizing member 4 can be rotated around the shaft portions 4c and 4d as fulcrums.

When connecting, the flat conductor F is inserted into the opening 1a of the case 1 with the pressing member open, and is positioned so as to correspond to the contact portions 2b, 3b of the first and second terminals 2, 3 . Then, the pressing member 4 is operated to obtain the closing state of the pressing member, whereby the flat conductor F is brought into pressure contact with the contact portions 2b, 3b.

In addition, when the pressurizing member 4 is reversely operated to obtain the pressurizing member open state, the flat conductor F can be easily detached from the opening 1 a of the housing 1 .

In the connector shown in FIGS. 12 to 13B , when a connection object to which the flat conductor F is not inserted into the opening 1 a of the housing 1 is not attached, the pressurizing member may be in an open state. In this state, when a load is applied to the pressing member 4, the pressing member 4 may fall off. Furthermore, when the object to be connected is not attached, the pressurizing member may be in a closed state. Also in this state, if a load is applied to the pressurizing member 4, the pressurizing member 4 may fall off similarly.

Specifically, when the so-called dry operation of operating the pressurizing member 4 is performed when the object to be connected is not attached, as in the case of connector inspection, the center of the pressurizing member 4 is curved and arched, and the shaft portion 4c is detached from the first terminal 2. The pressing member 4 may come off.

The reason why the pressing member 4 falls off easily is that the pressing member 4 is rotatably supported only by the rotation supporting portion 2 a of the first terminal 2 , and the second terminal 3 does not play any role in preventing the pressing member 4 from coming off.

Contents of the invention

Therefore, it is an object of the present invention to provide a connector in which the detachment prevention effect of the pressing member during the opening and closing operation is improved.

According to one aspect of the present invention, there is obtained a connector characterized in that it has two types of contacts, a case holding the contacts, and an openable and closable connector for bringing the object to be connected into pressure contact with the contacts. The contacts have an upper arm and a lower arm, the press members have a cam and a locking part, and the respective lower arms of the contacts have a function for contacting the object to be connected. The upper arm of one of the two contacts extends toward one side of the cam and has a recess for receiving the cam, the other of the two contacts The upper arm portion has a protrusion that functions as a stopper for the locking portion.

According to another aspect of the present invention, there is obtained a connector characterized by including an insulating housing, first and second contacts held by the housing, and a connector for connecting an object to be connected with the The movable pressing member contacted by the first and second contacts, said first and second contacts respectively comprising an upper arm portion and a lower arm portion located on both sides of a disposition area for disposing said connection object, the pressing member includes a rotatable cam engaged with the upper arm of the first contact, and the respective lower arms of the first and second contacts include a The contact portion of the object contact is provided with a U-shaped end at the end of the upper arm of the first contact, and the U-shaped end has a recess for receiving the cam, and the upper arm of the second contact A protrusion is provided at the end of the portion, and the protrusion protrudes in a direction opposite to the direction of the recess, and the detachment of the pressing member is prevented by the recess and the protrusion.

Detailed ways

First, the overall structure of the connector according to the embodiment of the present invention will be described with reference to FIGS. 1 to 4 .

The illustrated connector 10 is suitable for surface mounting on, for example, a printed circuit board (not shown), and includes a housing 11 having a shape elongated along the first direction A1. The housing 11 is made of insulating synthetic resin. Both ends in the first direction A1 of the housing 11 are respectively equipped with metal pressing parts 12 . The pressing member 12 has a soldering portion 12 a to be soldered to a printed circuit board or the like to be mounted.

On the housing 11 , a plurality of contacts, which are conductive terminals, are arranged in parallel at a constant interval along the first direction A1 and are fixedly held. These contacts include two types of contacts, namely first contacts 13 and second contacts 14 . In this embodiment, an arrangement method in which two first contacts 13 and one second contact are arranged alternately along the first direction A1 is adopted, but it is not limited to this, and various other arrangements may also be adopted. .

The illustrated connector 10 further includes a pressing member 15 called an actuator capable of opening and closing operations by the first contact 13 and the second contact 14 as will be described in detail later. The pressing member 15 extends linearly in the first direction A1 along the housing 11 . 1 and 4 show the open state of the pressurizing member 15 .

Referring to FIG. 6A and FIG. 6B together with FIG. 5 , the pressurizing member 15 will be described.

The pressurizing member 15 is an elongated plate-shaped member made of a flexible material such as nylon-based plastic, and thus can be slightly bent with respect to the first direction A1. In particular, it is easy to understand that the pressing member 15 is easily bent in the plate thickness direction. Also, the pressing member 15 allows slight bending in the plate width direction.

The pressing member 15 has a first groove portion 15 a ( FIG. 6A ) and a second groove portion 15 b ( FIG. 6B ) corresponding to the first contacts 13 and the second contacts 14 one-to-one. That is, FIG. 6A is a partially cut sectional view of the first groove portion 15a, and FIG. 6B is a partially cut sectional view of the second groove portion 15b. The pressurizing member 15 has a cam 15c as a shaft provided in the first groove 15a, and a locking part 15d provided in the second groove 15b.

The cam 15c has a substantially elliptical cross-sectional shape, is disposed in the middle of the first groove portion 15a, and has both ends integrally formed on opposing wall surfaces defining the first groove portion 15a. The locking portion 15d protrudes from the bottom surface of the second groove portion 15b and is integrally formed on the opposing wall surface defining the second groove portion 15b. It should be noted that the shape and size of the cam 15c and the locking portion 15d will be clarified by describing the operation of the connector described later.

Referring to FIG. 7A and FIG. 7B , the description of the overall structure of the connector 10 will be continued. 7A and 7B show the open state of the pressurizing member 15 without the object to be connected.

The housing 11 has an insertion opening 11a at the front end (left end in the figure) in a second direction A2 perpendicular to the first direction A1 for inserting a connection object, and an arrangement area 11b next to the insertion opening 11a. As will be described later in detail, the object to be connected is connected to the connector 10 by operating the pressurizing member 15 in a closed state with its end portion passed through the insertion port 11a and placed in the arrangement area 11b.

As shown in FIG. 7A , the first contact 13 has a fixed portion 13a fixed to the housing 11 and extends from the fixed portion 13a to the front (left in the figure) along the second direction A2 and is located at the upper and lower sides of the arrangement area 11b. side upper arm portion 13b and lower arm portion 13c. 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 portion 13b of the first contact 13, that is, in the vicinity of the free end, a rotation guide end portion (hereinafter referred to as “U-shaped end portion”) for guiding the rotation of the cam 15c of the pressing member 15 is provided. 16. The U-shaped end portion 16 has a concave portion 16a that accommodates the rotatable cam 15c and extends downward along a third direction A3 that is perpendicular to the first and second directions A1 and A2.

The end portion of the lower arm portion 13c of the first contact 13, that is, the portion near the free end is formed with a contact portion 13d for obtaining electrical contact with a connection object. The contact portion 13d has a shape slightly protruding upward at a position substantially facing the recessed portion 16a.

As shown in FIG. 7B , the second contact 14 has a fixed portion 14a fixed to the housing 11 and extends from the fixed portion 14a to the front (left in the figure) along the second direction A2 and is located at the upper and lower sides of the arrangement area 11b. side upper arm portion 14b and lower arm portion 14c. The front ends of the upper arm portion 14b and the lower arm portion 14c are free ends.

At the end of the upper arm portion 14b of the second contact 14, that is, in the vicinity of the free end, a stopper end (hereinafter referred to as “T-shaped end”) functioning as a stopper of the pressing member 15 is formed. 17. The T-shaped end portion 17 has a straight portion 17a provided at a position facing the locking portion 15d, and a protrusion 17b protruding upward from the straight portion 17a in the direction opposite to the direction along the concave portion 16a, that is, the third direction A3. It should be noted that the T-shaped end portion 17 deviates from the U-shaped end portion 16 in the first direction A1 shown in FIGS. 1 and 4 .

In the state shown in FIGS. 7A and 7B , on the side of the linear portion 17a of the second contact 14 viewed from the protrusion 17b, specifically, on the side of the fixed portion 14a, the locking portion 15d of the pressing member 15 and the locking portion 15d are aligned with each other. The straight portion 17a abuts against it. In this way, the movement of the pressing member 15 in the opening direction is blocked by the second contact 14 .

Now, as shown in FIGS. 7A and 7B , when the connection object is not attached and the pressing member 15 is in the open state, it is assumed that an external force acting forward along the second direction A2 acts on the pressing member 15 . In this case, since the pressing member 15 is made of a flexible material, the middle portion in the first direction A1 (see FIG. 1 ) is bent in an arched shape and moves forward in the second direction A2. However, since the cam 15c is engaged with the wall portion 16b defining the side surface of the concave portion 16a of the U-shaped end portion 16, and as shown in FIG. Since the protrusion 17b of 17 is engaged, the pressing member 15 is prevented from coming off from the first and second contacts 13 and 14 . In this way, the cam 15c is prevented from coming off from the first contact 13 by both the wall portion 16b and the protrusion 17b defining the side surface of the recessed portion 16a. Therefore, even in the state shown in FIGS. 7A and 7B , detachment of the pressing member 15 can be more reliably prevented.

When the pressing member 15 is rotated counterclockwise in the figure 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 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 figure to the position shown in FIG. 10A and FIG. The free end side of 14b is in contact with the linear portion 17a. Therefore, the movement of the pressing member 15 in the closing direction is blocked by the second contact 14 .

Now, as shown in FIGS. 10A and 10B , when the connection object is not attached and the pressurizing member 15 is in the closed state, it is assumed that an external force acting rearward along the second direction A2 acts on the pressurizing member 15 . In this case, since the pressurizing member 15 is made of a flexible material, the middle portion in the first direction A1 (see FIG. 1 ) is bent in an arcuate shape and moves backward in the second direction A2. However, since the cam 15c is engaged with the wall portion 16c defining the side surface of the concave portion 16a of the U-shaped end portion 16, and as shown in FIG. Since the protrusion 17b of 17 is engaged, the pressing member 15 is prevented from coming off from the first and second contacts 13 and 14 . In this way, the cam 15c is prevented from coming off from the first contact 13 by both the wall portion 16c and the protrusion 17b that define the side surface of the recessed portion 16a. Therefore, in the state shown in FIGS. 10A and 10B , detachment of the pressing member 15 can be more reliably prevented.

As described above, the connector 10 has a stopper structure that prevents the pressurizing member 15 from bending into a bow when the pressurizing member 15 is clamped by two kinds of contacts and a load is applied to the pressurizing member 15 to disengage from the contacts. break away. Therefore, when the object to be connected is not inserted, it is possible to prevent the pressure member 15 from falling off the contact due to the operation of the pressure member 15 or when a load acts on the pressure member 15 . Therefore, there is little possibility that the pressure member 15 will be detached even when a so-called dry operation is performed to open and close the pressure member 15 in the unattached state of the object to be connected, for example, during a connector inspection.

11A and 11B show a state where a connection object 18 made of a flat conductor called FPC or FFC is connected to the connector 10 . At this time, the pressing member 15 is in the closed state.

As shown in FIG. 11A , as the cam 15 c of the pressing member 15 lifts the upper arm portion 13 b of the first contact 13 , the pressing member 15 presses the object to be connected 18 downward by its reaction force. Therefore, the first contact portion 18 a on the lower surface of the object to be connected 18 comes into pressure contact with the contact portion 13 d of the first contact 13 .

In addition, as shown in FIG. 11B , the second contact portion 18 b on the lower surface of the object to be connected 18 pressed downward by the pressing member 15 also comes into pressure contact with the contact portion 14 d of the second contact 14 . In this way, the object to be connected 18 is electrically connected to the first and second contacts 13 and 14 . In this state, the locking portion 15 d of the pressing member 15 is separated from the upper arm portion 14 b of the second contact 14 .
