Description

Connector

The present invention relates to a connector of a type that can be connected to a connection object by operating a pressurizable member that can be opened and closed.

For example, a flat conductor called FPC or FFC is often used inside a liquid crystal television. A connector having a pressurizing member that can be opened and closed can be used for the connection of the connection object of the flat conductor. Such a connector is disclosed in Japanese Patent No. 4390821 (Patent Document 1) under the name "electrical connector for a flat conductor".

The connector disclosed in Patent Document 1 will be briefly described with reference to the 12th, 13th, and 13th drawings.

a connector shown in FIGS. 12 to 13B, comprising: an insulative housing 1; first and second terminals 2, 3, which are held on the housing 1 and separated from each other; and a pressing member 4, The flat conductor F is crimped to the first and second terminals 2, 3. The pressurizing 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 the groove portions 4a and 4b, respectively. A shaft portion 4c is rotatably supported on the rotation support portion 2a of the first terminal 2. The other shaft portion 4d is disposed between the two restriction guide portions 3a of the second terminal 3. Thereby, the pressing member 4 can perform a turning operation with the shaft parts 4c and 4d as a fulcrum.

At the time of connection, the flat conductor F is inserted into the opening 1a of the casing 1 in a state where the pressing member is opened, and is placed at a position corresponding to the contact portions 2b, 3b of the first and second terminals 2, 3. Then, the pressing member 4 is operated to be in a closed state of the pressing member, whereby the flat conductor F is pressed against the contact portions 2b and 3b.

Further, when the pressing member 4 is operated in the reverse direction and the pressing member is opened, the flat conductor F can be easily detached from the opening 1a of the casing 1.

In the connector of the 12th to 13th drawings, when the flat conductor F is not inserted into the opening 1a of the casing 1 and the connection object is not attached, the pressing member may be opened. When it is in this state, if a load is applied to the pressurizing member 4, the pressurizing member 4 may be detached. In addition, when the object to be connected is not attached, there is a case where the pressing member is in a closed state. When it is in this state, if a load is applied to the pressurizing member 4, the pressurizing member 4 may be detached.

Specifically, when the so-called vacant operation of the pressing member 4 is performed when the object to be connected is not attached, such as when the connector is inspected, the vicinity of the center of the pressing member 4 is bent into an arc shape, and the shaft portion 4c is self-contained. The first terminal 2 is disengaged, causing the pressing member 4 to disengage.

The reason why the pressing member 4 is easily detached is because the pressing member 4 is rotatably supported only by the rotation supporting portion 2a of the first terminal 2, and the second terminal 3 does not exert any effect on preventing the pressing member 4 from being detached. .

Therefore, an object of the present invention is to provide a connector capable of improving the effect of preventing the release of the pressing member that is opened and closed.

According to an aspect of the present invention, a connector is provided, comprising: two kinds of contacts; a housing for holding the contact; and an openable and closable pressing member for crimping the connection object In the contact member, each of the contact members has an upper arm portion and a lower arm portion; the pressing member has a cam and a locking portion; each of the lower arm portions of the contact member has a contact for the connection object a contact portion; the upper arm portion of one of the two types of contacts extends to one side of the cam and has a recess for receiving the cam, and the upper arm portion of the other of the two contacts has A projection that functions as a stopper of the locking portion.

[Formation of the Invention]

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

The connector 10 shown in the drawing is suitably mounted on, for example, a printed circuit board (not shown), and includes a casing 11 having a shape elongated in a first direction A1. The casing 11 is made of an insulating synthetic resin. Each end of the both ends of the housing 11 in the first direction A1 has a metal hold-down 12, respectively. The fixed presser 12 has a welded portion 12a that is soldered to a printed circuit board or the like to be mounted.

The plurality of contacts as the conductive terminals are arranged in parallel with each other at a constant interval in the first direction A1 and are fixedly held by the casing 11. These contacts comprise two types of contacts, namely a first contact 13 and a second contact 14. In this embodiment, the arrangement of the two first contacts 13 and the second contacts 14 is alternately arranged in the first direction A1. However, the present invention is not limited to this embodiment, and various other arrangements may be employed. form.

As will be described later in detail, the illustrated connector 10 further includes a pressing member 15 which is also referred to as an actuator which is provided to open and close with the first contact member 13 and the second contact member 14. The pressing member 15 extends linearly in the first direction A1 along the casing 11. Further, the first and fourth figures show the open state of the pressing member 15.

The pressing member 15 will be described with reference to Fig. 5 and Figs. 6A and 6B.

Since the pressing member 15 is an elongated plate made of a flexible material such as a nylon-based plastic, it can be slightly bent with respect to the first direction A1. In particular, it should be easily understood that the pressing member 15 is easily bent in the thickness direction. Further, the pressing member 15 is a member that allows it to be slightly bent in the thickness direction.

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

The cam 15c has a cross-sectional shape substantially parallel to the elliptical cross section, and is disposed at the center of the first groove portion 15a and integrally formed at both ends of the opposing wall surface of the predetermined 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 of the predetermined second groove portion 15b. Further, the shape and size of the cam 15c and the locking portion 15d can be clarified by the operation of the connector to be described later.

Referring again to FIGS. 7A and 7B, the overall configuration of the connector 10 will be described. 7A and 7B show the state in which the connection object is not mounted and the pressing member 15 is opened.

The casing 11 has an insertion opening 11a for inserting a front end (left end in the drawing) in a second direction A2 orthogonal to the first direction A1, and an arrangement area 11b for connecting the insertion opening 11a. As will be described in detail later, the connection target is connected to the connector 10 by operating the pressurizing member 15 in a state where the end portion is placed in the arrangement region 11b through the insertion port 11a.

As shown in FIG. 7A, the first contact member 13 has a fixing portion 13a fixed to the casing 11, and an upper arm portion 13b and a lower arm portion 13c which are forwardly forward from the fixing portion 13a in the second direction A2 ( The left side of the figure extends and is located on the upper and lower sides of the arrangement area 11b. The front ends of the upper arm portion 13b and the lower arm portion 13c are free ends.

A rotation guiding end portion (hereinafter referred to as a "U-shaped end portion 16") for guiding the rotation of the cam 15c of the pressing member 15 is provided at an end portion of the arm portion 13b at the upper end of the first contact member 13, that is, in the vicinity of the free end. . The U-shaped end portion 16 has a recessed portion 16a that rotatably houses the cam 15c and is recessed downward in the third direction A3 orthogonal to the first and second directions A1, A2.

A contact portion 13d capable of making electrical contact with the connection object is formed at an end portion of the arm portion 13c below the first contact member 13, that is, in the vicinity of the free end. The contact portion 13d has a shape slightly protruding upward at a position substantially opposed to the concave portion 16a.

As shown in FIG. 7B, the second contact member 14 has a fixing portion 14a fixed to the casing 11, and an upper arm portion 14b and a lower arm portion 14c which are oriented forward from the fixing portion 14a in the second direction A2. (left side in the figure) extends to the upper and lower sides of the arrangement area 11b. The front ends of the upper arm portion 14b and the lower arm portion 14c are free ends.

At the end portion of the arm portion 14b on the upper side of the second contact member 14, that is, in the vicinity of the free end, a stopper end portion functioning as a stopper of the pressing member 15 is provided (hereinafter, referred to as a "T-shaped end portion". 17"). The T-shaped end portion 17 has a linear portion 17a provided at a position opposed to the locking portion 15d, and a projection 17b that faces the direction opposite to the direction of the concave portion 16a from the straight portion 17a, that is, in the third direction A3. Stand up. Further, the T-shaped end portion 17 is located at a position deviated from the U-shaped end portion 16 in the first direction A1 shown in the first and fourth figures.

In the state shown in Figs. 7A and 7B, the locking portion 15d of the pressing member 15 is on the side viewed from the projection 17b of the straight portion 17a of the second contact member 14, specifically, the fixing portion 14a. The side abuts on the straight portion 17a. In this manner, the second contact member 14 can lock the action of the pressing member 15 in the opening direction.

As shown in FIGS. 7A and 7B, it is assumed that the pressing member 15 is in the open state when the pressing member 15 is not mounted, and the pressing force is applied to the pressing member 15 in the second direction A2. In this case, since the pressing member 15 is made of a flexible material, the intermediate portion in the first direction A1 (refer to FIG. 1) is curved in an arc shape, and also in the second direction A2. Move ahead. However, not only the cam 15c is engaged with the wall portion 16b of the side surface of the recess 16a defining the U-shaped end portion 16, but as shown in Fig. 7C, the locking portion 15d of the pressing member 15 is also engaged with the T. The projection 17b of the end portion 17 of the gauze prevents the pressing member 15 from being detached from the first and second contacts 13, 14. Thus, by defining both the wall portion 16b and the projection 17b on the side surface of the recessed portion 16a, the cam 15c can be prevented from being detached from the first contact member 13. Therefore, even in the state shown in Figs. 7A and 7B, the detachment of the pressing member 15 can be further reliably prevented.

When the pressing member 15 is rotated in the counterclockwise direction in the drawing to the position shown in Figs. 8A and 8B, the locking portion 15d of the pressing member 15 is separated from the upper arm portion 14b of the second contact member 14. When the pressing member 15 is further rotated in the counterclockwise direction in the drawing to the positions shown in Figs. 9A and 9B, the locking portion 15d of the pressing member 15 passes over the projection 17b of the second contact member 14.

When the pressing member 15 is further rotated in the counterclockwise direction in the figure to the positions shown in Figs. 10A and 10B, the locking portion 15d of the pressing member 15 is opposite to the projection 17b of the second contact member 14. The side, that is, the free end side of the upper arm portion 14b abuts against the straight portion 17a. Therefore, the action of the pressing member 15 in the closing direction can be locked by the second contact member 14.

As shown in FIGS. 10A and 10B, it is assumed that the pressing member 15 is in the closed state when the object to be connected is not mounted, and the pressing force is applied to the pressing member 15 in the second direction A2. In this case, since the pressing member 15 is made of a flexible material, the intermediate portion in the first direction A1 (refer to FIG. 1) is curved in an arc shape, and also in the second direction A2. Move behind. However, not only the cam 15c is engaged with the wall portion 16c of the side surface of the recess 16a defining the U-shaped end portion 16, but as shown in Fig. 10C, the locking portion 15d of the pressing member 15 is also engaged with the T. The projection 17b of the end portion 17 of the gauze prevents the pressing member 15 from being detached from the first and second contacts 13, 14. Thus, by defining both the wall portion 16c and the projection 17b on the side surface of the recessed portion 16a, the cam 15c can be prevented from being detached from the first contact member 13. Therefore, even in the state shown in Figs. 10A and 10B, the detachment of the pressing member 15 can be further reliably prevented.

As described above, the connector 10 has a stopper structure which prevents the pressing member 15 from being bent into an arc shape and being detached from the contact member when the pressing member 15 is held by the two kinds of contacts and a load is applied to the pressing member 15. of. Therefore, when the object to be joined is not inserted, it is possible to prevent the pressurizing member 15 from being detached from the contact member due to the operation of the pressurizing member 15, and the detachment of the pressurizing member 15 from the contact member when a load is applied to the pressurizing member 15 . Therefore, even when the connector is inspected, the so-called empty operation of opening and closing the pressurizing member 15 in a state where the object to be connected is not attached does not cause the pressurizing member 15 to be detached.

11A and 11B show a state in which the connection object 18 composed of a flat conductor called FPC or FFC is connected to the connector 10. At this time, the pressing 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 member 13, the pressing member 15 presses the connecting object 18 downward by the reaction force. Therefore, the first contact portion 18a under the connection object 18 is crimped to the contact portion 13d of the first contact member 13.

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