Description

Connector for FFC/FPC

The present invention relates to a connector for FFC/FPC. In particular, it relates to a connector for FFC/FPC that electrically connects a flat flexible cable such as FFC (Flexible Flat Cable) or FPC (Flexible Printed Circuit) and a hard printed circuit board. In this specification, flat flexible cables are collectively referred to as FFC, and the present invention is particularly directed to a so-called ZIF (Zero Insertion Force) type FFC that requires little force when inserting and extracting an FFC. /This is about the structure of the connector for FPC.

The connector for FFC/FPC is constructed by protruding a rectangular parallelepiped-shaped connector body from the mounting surface of a printed board on which electronic components are mounted, through an insertion opening opened in the printed board, to the anti-mounting surface on the opposite side of the mounting surface. With this, FFC is inserted and extracted from the half-mounted surface side (for example, see Patent Document 1).

A connector for FFC/FPC according to the prior art of Patent Document 1 (hereinafter abbreviated as 'connector') includes a housing in the shape of a rectangular parallelepiped, a plurality of contacts juxtaposed inside the housing, and these plurality of contacts. It is equipped with a flat cover housing that stabilizes the connection with FFC or FPC. Hereinafter, a connector for FFC/FPC connected to FFC will be described.

The rectangular parallelepiped-shaped housing is provided to protrude from the mounting surface Sf of the printed board on which the electronic components are mounted, through a rectangular insertion opening opened in the printed board, to the semi-mounting surface Bf on the opposite side to the mounting surface Sf. do. That is, the housing with a plurality of contacts into which the FFC is inserted protrudes from the semi-mounted surface Bf of the printed circuit board. Each of the plurality of contacts has a pair of lead portions and a contact portion formed by an elastic arm and a fixed arm. The pair of lead portions extend in opposite directions, and each plate thickness surface is soldered to a plurality of lands on the mounting surface Sf formed around the insertion opening. Thereby, the connector is electrically connected to the printed board and is fixed. The contact portion is formed in a U-shape in the concave portion where the FFC is inserted and inserted with respect to the half-mounted surface Bf.

The cover housing covers a portion constituting the concave portion in an openable and closable manner. In the concave portion, an elastic arm and a fixed arm constituting the contact portion extend substantially in parallel.

With the cover housing open, the FFC can insert its terminal between the elastic arm and the fixed arm. When the cover housing is closed, the proximal end side of the cover housing can press the elastic arm through the FFC. As a result, the conductor pattern formed at the terminal of the FFC and the contact point of the elastic arm are electrically connected, contributing to stabilization of the connection.

Patent Document 1: Daily Patent Publication No. 2019-128984

The connector according to Patent Document 1 is mounted on a printed circuit board using an automatic mounting machine with the cover housing closed. In mounting, the connector is inserted from the mounting surface Sf of the printed circuit board into the insertion opening.

A printed circuit board may be equipped with a large number of electronic components for lighting. In a printed board on which a large number of electronic components for lighting are mounted, it is desirable to make the opening area of the insertion opening small in order to have a larger mounting area for the electronic components.

By reducing the external size of the connector, the opening area of the insertion opening can be reduced. To achieve this, it is conceivable to make the width of the cover housing shorter. In a multi-pole connector, if the width of the cover housing is shortened, there is a risk that the central portion of the cover housing may bend due to the reaction force of the elastic arm when the cover housing is closed (connected to the FFC). This is because the cover housing is rotationally supported by the housing at both ends in the longitudinal direction.

The present invention was made in view of these problems, and its purpose is to provide a connector for FFC/FPC that can expand the mounting area of electronic components and ensure the strength of the cover housing.

The present invention adopts a locking structure that can maintain the cover housing in an open state with respect to the housing. With this configuration, a configuration in which the width of the connector is narrower is realized so that the insertion opening into the board to be mounted is smaller. The cover housing is difficult to bend and has a thickness that allows for higher strength, and provides a cover housing configuration that exceeds the width of the insertion opening when the cover housing is closed to the housing. Based on this configuration, the following new connector for FFC/FPC was invented.

(1) An FFC/FPC connector that is mounted on the printed board through an insertion opening formed in the printed board and electrically connects the printed board and the FFC, with an FFC on one side perpendicular to the longitudinal direction in the longitudinal direction. A housing having a concave portion into which a device is inserted is formed, a cover housing that covers a portion constituting the concave portion in an openable manner, and a plurality of contacts provided inside the housing and arranged in parallel in the longitudinal direction of the housing. Between both ends, a first width of the housing is defined by an outer surface of the housing on which the plurality of contacts are arranged side by side, and the corresponding insertion opening has a second width sufficient to insert the outer surface of the housing. wherein the cover housing has an open state in which the cover housing is caught on the housing without exceeding the range of the first width or the second width on the outer surface of the housing, and the range of the first width or the second width. It has a closed state of the cover housing exceeding .

(2) It is desirable to have a locking structure that can maintain the open state of the cover housing with respect to the housing.

(3) In the open state of the cover housing, the cover housing is hardened by exposing a hardness slope on the outer surface of the housing, and the housing is inserted into the insertion opening, and the cover housing is In the closed state, at least a portion of the longitudinal slope becomes a plane facing the printed circuit board around the insertion opening, and the housing cannot be inserted into the insertion opening.

(4) At both longitudinal ends of the housing, a pair of guide grooves are further provided for guiding both sides of the FFC to the concave portion, and the guide grooves include a first inclined surface and a second opposing surface so as to approach the concave portion. It is composed of an inclined surface, and the first inclined surface is formed on a side of the printed circuit board rather than the second inclined surface, and has a slope that has a steeper angle than the second inclined surface, and the second inclined surface is formed on a side of the printed circuit board more than the second inclined surface. It has a gentle slope.

(5) The first width of the housing is reduced to 60% to 80% of the width perpendicular to the longitudinal direction at both ends of the housing in the longitudinal direction.

The connector for FFC/FPC according to the present invention adopts a locking structure that can hold the cover housing in an open state with respect to the housing, so that when the cover housing is open, the width of the connector can be narrowed and the width of the insertion opening can be reduced. It can be done narrowly. In addition, when the cover housing is closed with respect to the housing, the width of the cover housing is made larger than the width of the insertion opening. As a result, the mounting area for electronic components can be expanded, and the strength of the cover housing can also be increased.

[Configuration of connector for FFC/FPC]

(Full configuration)

First, referring to FIGS. 1 to 12, the overall configuration of the FFC/FPC connector according to the present invention will be described. The FFC/FPC connector (hereinafter abbreviated as 'connector') 10 according to one embodiment of the present invention includes a printed board 1p on which an electronic component Ep is mounted on a mounting surface Sf and an FFC ( 8f) can be connected electrically. Here, FFC is exemplified as a flexible wiring member connected to the connector, but FPC can be similarly connected instead of FFC. The connector 10 includes a housing 1, a cover housing 2, and a plurality of contacts 3. Additionally, the connector 10 is provided with a pair of bearing metal fittings 4, 4 (see Fig. 5).

The connector 10 is connected from the mounting surface Sf of the printed board 1p on which the electronic component Ep is mounted, through the insertion opening opened in the printed board 1p, to the semi-mounted surface opposite to the mounting surface Sf. (Bf) has a configuration in which the housing 1 provided with a plurality of contacts 3 protrudes.

In the longitudinal direction of the housing 1, a concave portion 11 into which the FFC 8f can be inserted is formed on one side perpendicular to the longitudinal direction. The cover housing 2 is configured to cover a portion of the concave portion 11 of the housing 1 in an openable manner (see FIGS. 3 and 4 or FIGS. 8 to 10). A plurality of contacts 3 are arranged side by side inside the housing 1.

On the printed board 1p, electronic components Ep such as LED chips are arranged vertically and horizontally on the mounting surface Sf. By making the opening area of the insertion opening where the connector 10 is mounted smaller, the mounting area of the electronic component Ep can be relatively enlarged.

The printed circuit board 1p is provided with an insertion opening through which the housing 1 can be inserted from the mounting surface Sf side. This insertion opening has the minimum size for inserting the housing 1 from the mounting surface Sf side with the cover housing 2 as the head in a state where the cover housing 2 of the housing 1 is opened. 3 and 8, the width W1 of the insertion opening through which the housing 1 is inserted into the area where the plurality of contacts 3 are arranged in parallel is the length through which both longitudinal ends of the housing 1 are inserted. The width Wo of the insertion opening perpendicular to the direction is reduced by about 60% to 80%, more specifically, about 65% to 75%. Therefore, in the open state of the cover housing 2 in which the cover housing 2 is stiffened with respect to the housing 1, the range of the width W1 of the insertion opening is not exceeded, and more preferably, the width W2 of the housing 1 is not exceeded. The cover housing (2) is hung on the housing (1) without exceeding the range. As a result, the opening area of the insertion opening where the connector 10 is mounted can be made smaller.

(Configuration of housing)

Next, the configuration of the housing 1 according to the embodiment will be described with reference to FIGS. 3 to 5 and FIGS. 8 to 11A to 11C. The housing 1 is obtained by molding an insulating synthetic resin into a predetermined shape such as a combination of multiple rectangular parallelepiped shapes. The housing 1 has a plurality of locking grooves formed in a comb-tooth shape for press-fitting the plurality of contacts 3. The housing 1 has both longitudinal ends that guide the insertion of the FFC 8f, and a plurality of contacts 3 between these ends, and the width of most of the longitudinal regions is reduced more than that of the two ends. has

The housing 1 has a pair of shading portions 11f and 11f. A pair of shading portions 11f and 11f are formed at both ends of the housing 1 in the longitudinal direction. When the housing 1 is inserted into the insertion opening of the printed board 1p, the press-fit depth of the housing 1 is increased by the pair of shading portions 11f and 11f in contact with the mounting surface Sf of the printed board 1p. It can be stipulated.

Additionally, a pair of guide grooves 12d and 12d are formed on both ends of the housing 1 in the longitudinal direction. The pair of guide grooves 12d and 12d are configured to guide both sides near the end of the FFC 8f and guide the end of the FFC 8f to the concave portion 11. Each guide groove 12d is composed of a first inclined surface 121 and a second inclined surface 122 that face each other so as to approach the concave portion 11. The first inclined surface 121 is formed closer to the printed board 1p than the second inclined surface 122, and has a steeper angle than the second inclined surface 122. Accordingly, the second inclined surface 122 has a gentler slope than the opposing first inclined surface 122.

When the FFC 8f is inserted from the opening side of the housing 1 along the guide groove 12d, for example, the end edge of the FFC 8f comes into contact with the first inclined surface 121, so that the FFC 8f The end edge faces the second inclined surface 122, and the end edge of the FFC 8f comes into contact with the second inclined surface 122, so that the FFC 8f is easily guided into the concave portion 11.

Additionally, convex portions 12t are provided at each vertex of the first inclined surface 121. In the FFC 8f inserted into the concave portion 11, the groove portion 8s (see Fig. 5) cut in both sides of the FFC 8f is caught by a pair of convex portions 12t and 12t. By doing so, it is possible to prevent the FFC 8f from falling off the connector 10.

In addition, a pair of slit openings 11d and 11d through which a pair of bearing metal fittings 4 and 4 can be press-fitted are provided at both ends of the housing 1 in the longitudinal direction. The pair of bearing metal fittings 4, 4 press-fitted into the pair of slit openings 11d, 11d can firmly support the shaft portion 2s protruding from both ends of the cover housing 2. Additionally, each bearing metal fitting 4 has a press-fitting piece 4s that can be press-fitted into the housing 1 (see Fig. 5).

A plurality of contacts 3 are arranged in parallel on the inside between both longitudinal ends of the housing 1, and a width W2 is defined by the outer surface of the housing 1. The open state of the cover housing 2 is entered and maintained within the range of the width W2. The width W2 is reduced by about 60% to 80%, more specifically, about 65% to 75% of the width We of the housing 1 perpendicular to the longitudinal direction at both longitudinal ends of the housing 1. On the other hand, in the closed state of the cover housing 2, the cover housing 2 has the width W2 of the housing so that its edge portion approaches the line connecting the vicinity of the entrances of the guide grooves 12d at both ends of the housing 1. It is constructed to protrude significantly from the exterior. The width Wm of the housing 1 in the closed state of the cover housing 2 may be larger than the width We of both longitudinal ends of the housing 1 depending on the shape of the cover housing 2.

(Configuration of cover housing)

Next, the configuration of the cover housing 2 according to the embodiment will be described with reference to FIGS. 3 to 5 or FIGS. 8 to 11A to 11C. The cover housing 2 is obtained by molding an insulating synthetic resin. Rather than being plate-shaped, the cover housing 2 has a prismatic shape in which the difference in the lengths of adjacent sides is not very large, and has a shape that resembles a parallelogram in cross section. This creates a structure that suppresses bending of the axis about the longitudinal direction. The prismatic longitudinal side edge portion is formed in a comb-tooth shape to receive a predetermined portion of the plurality of contacts 3, here, near the tip of each fixing arm 32, and a shaft portion 2s is formed between the comb teeth. is penetrating.

The cover housing 2 is rotationally supported by the housing 1 via the bearing fitting 4 by a pair of shaft portions 2s and 2s protruding from both ends in the longitudinal direction. Additionally, the axial portions 2s between the teeth of the cover housing 2 are rotatably supported by the fixing arms 32 of the contacts 3, respectively. More specifically, the axial portion 2s between the teeth of the cover housing 2 is rotatably supported in a concave shape near the tip of the fixing arm 32 of the contact 3. The point of contact with the concave shape of the fixing arm 32 at the shaft portion 2s between the teeth of the cover housing 2 moves to follow the concave shape of the fixing arm 32 in accordance with the rotation of the cover housing 2. do. The cross-sectional shape of the shaft portion 2s is a shape similar to an oval, or a straight line connecting the ends of a predetermined arc in a circular or oval shape, taking into account the relationship of engagement and support with the concave shape of the fixing arm 32. It has a shape excluding one side of the division.

For example, as shown in FIGS. 3, 8, 11A, and 11B, when the cover housing 2 is opened with respect to the housing 1, the housing 1 is inserted into the insertion opening of the printed circuit board 1p. It can work. The cover housing 2 has a hardened structure with the hardness inclined surface 22 exposed on the outer surface of the housing 1. The cover housing 2 has a predetermined surface in flush contact with the horizontal surface on the outer surface of the housing 1, and the elastic action of the fixing arm 32 supporting the shaft portion 2s makes the cover housing 2. Contributes to maintaining the open state of (2). In the open state of the cover housing 2, the FFC 8f can be inserted into the concave portion 11 of the housing 1.

For example, as shown in FIGS. 4, 9, and 11C, when the cover housing 2 is closed with respect to the housing 1, at least a portion of the longitudinal slope 22 is aligned with the printed circuit board around the insertion opening. It becomes the plane opposite to (1p) (half-real scene (Bf)). The cover housing 2 has a shape that largely protrudes from the outer surface of the housing with a width W2. In this form, the housing 1 cannot be inserted into the insertion opening. In the closed state of the cover housing 2, the concave portion of the housing 1 is formed by the support provided by the base end (pressable form) and the shaft portion 2s and the fixing arm 32 of the cover housing 2. The FFC (8f) inserted into (11) is pressed against the proximal end of the cover housing (2). As a result, the terminal of the FFC 8f is fixed, and the conductor pattern provided at the terminal of the FFC 8f and the elastic arm 31 are electrically connected. From its cross-sectional shape, it can be seen that the shaft portion 2s is supported by the concave shape of the fixing arm 32 so that it is difficult to return to its original position, and acts to maintain the closed state of the cover housing 2.

As shown in FIG. 5 or FIG. 13 , the cover housing 2 has a pair of triangular prism-shaped peaks 21c and 21c respectively protruding from some side surfaces of both ends in the longitudinal direction. The pair of peaks 21c and 21c are arranged in opposite directions. On the other hand, as shown in FIGS. 4 to 6, FIG. 9 or FIG. 13, the housing 1 has a length of the housing 1 on which a pair of bearing fittings 4 and 4 and awning parts 11f and 11f are disposed. As the inner side (inner wall) of both ends, there is a pair of triangular pillar-shaped ridges 12c and 12c that protrude from the surface area opposite to each side on which the ridge 21c of the cover housing 2 is formed. there is. The pair of peaks 12c and 12c are arranged to face each other.

As shown in FIG. 4, when the cover housing 2 is rotated as shown in FIG. 3 from the state in which the cover housing 2 is closed with respect to the housing 1, the peak portion 21c of the cover housing 2 is By climbing over the ridge 12c of the housing 1, the open state of the cover housing 2 can be maintained. Additionally, the peak of the mountain portion 21c is in contact with the inner wall of the housing 1.

In this way, the connector 10 has a shape that cannot be inserted into the insertion opening when the cover housing 2 is closed with respect to the housing 1, and when the cover housing 2 is open with respect to the housing 1, the connector 10 has a shape that cannot be inserted into the insertion opening. It has a shape that allows insertion through an insertion opening. More preferably, as shown in FIGS. 8 and 13, it has a locking structure capable of maintaining the open state of the cover housing 2 with respect to the housing 1. The cover housing 2 is arranged to overlap within the area of the fixing arm 32 in the open state, and is within the range of the width W2 of the housing 1. As a result, when inserting the housing 1 into the insertion opening of the printed circuit board 1p, the cover housing 2 does not interfere with insertion.

(Configuration of contact)

Next, the configuration of the contact 3 according to the embodiment will be described with reference to FIG. 8 or FIG. 9 and FIGS. 11A to 11C. The plurality of contacts 3 can each be obtained by punching a conductive metal plate into a predetermined shape. The contact 3 can be, for example, a copper alloy, but is not limited to copper alloy.

Each contact 3 has a pair of lead portions 3r, 3r extending in opposite directions in the horizontal direction on one side of the vertical direction, and a pair of lead portions 3r, 3r extending in one direction of the horizontal direction on the other side of the vertical direction. It is composed of an elastic arm (31) and a fixed arm (32). The plate thickness surfaces of each of the pair of lead portions 3r, 3r are soldered to predetermined lands of a plurality of lands on the mounting surface Sf formed around the insertion opening of the printed circuit board 1p, thereby forming the connector 10. is fixed to the printed board (1p).

In addition, the elastic arm 31 and the fixed arm 32 of the contact 3 are arranged to correspond to the concave portion 11 of the housing 1 on the semi-mounted surface Bf side of the printed board 1p. . Additionally, the elastic arm 31 and the fixed arm 32 have a U-shaped shape extending substantially parallel from the proximal end of the contact 3. The vicinity of the tip of the elastic arm 31 has a shape that serves as a contact point for connection to the conductor pattern of the terminal of the FFC 8f. The vicinity of the tip of the fixing arm 32 has a shape (concave shape) that receives the shaft portion 2s of the cover housing 2.

Referring to FIG. 11A, in the state where the cover housing 2 is opened, the elastic arm 31 and the fixed arm 32 allow the terminal of the FFC 8f to be inserted between them (U-shaped concave portion). (see Figure 11b). From the state shown in FIG. 11B, the cover housing 2 is rotated clockwise, and the terminal of the FFC 8f inserted into the concave portion can be fixed when the cover housing 2 is closed. Here, the proximal end side of the cover housing 2 is supported by the proximal end (pressable form), the shaft portion 2s, and the fixing arm 32, with the proximal end side of the cover housing 2 sandwiching the FFC 8f. The elastic arm (31) is pressed. As a result, the conductor pattern formed at the terminal of the FFC 8f and the contact point of the elastic arm 31 are electrically connected, thereby stabilizing the connection (see Fig. 11C).

By rotating the cover housing 2 counterclockwise from the state shown in FIG. 11C, the pressure on the elastic arm 31 is released, so the elastic arm 31 can return to the state shown in FIG. 11B. There is, and the FFC 8f can be pulled out from between the elastic arm 31 and the fixed arm 32. In addition, insertion and extraction of the FFC 8f is performed from the semi-mounted surface Bf side of the printed board 1p.

[Function of FFC/FPC connector]

Next, the operation and effects of the connector 10 will be explained while explaining the operation of the connector 10.

11A or 14A, in the connector 10, when the cover housing 2 is open, the opposing distance between the elastic arm 31 and the fixed arm 32 is the thickness of the terminal of the FFC 8f. It is set larger. As a result, the connector 10 realizes a ZIF (Zero Insertion Force) structure that requires little force when inserting and extracting the FFC 8f.

From the state shown in FIG. 14A, when the FFC 8f is inserted into the concave portion 11 along the guide groove 12d, the groove portions 8s (see FIG. 5) on both sides of the FFC 8f are formed into a pair of convex portions ( 12t, 12t). This can prevent the FFC 8f from falling off the connector 10 (see Fig. 14C).

1 to 10, the connector 10 according to the embodiment adopts a locking structure that can maintain the cover housing 2 in an open state with respect to the housing 1, thereby opening the cover housing 2. In this state, the width of the connector 10 can be narrowed. With this, the width of the insertion opening can be narrowed. As a result, the mounting area of the electronic component Ep can be expanded (see FIG. 1). In addition, since the connector 10 is configured to increase the width of the cover housing 2 beyond the width of the insertion opening, in the connector 10 with many poles of the contacts 3, the central portion of the cover housing 2 The bending strength can be strengthened.

The connector 10 is mounted on the printed circuit board 1p with the cover housing 2 opened using an automatic mounting machine equipped with a suction port. The connector 10 is inserted into the insertion opening from the mounting surface Sf of the printed board 1p. For this reason, the width W1 of the insertion opening in the area where the plurality of contacts 3 are arranged side by side between both longitudinal ends of the housing 1 is the width Wm of the housing 1 when the cover housing 2 is closed. It can be formed to be smaller than the wider width, and further, the size of the contact 3 represented by the width between the lead portions can also be reduced (see FIG. 9). Also, referring to FIG. 1, the connector 10 uses the upper surface of the housing 1 as an adsorption area.

Referring to FIG. 4 or FIG. 13, when the cover housing (2) is rotated from the state in which the cover housing (2) is closed with respect to the housing (1), the mountain portion (21c) of the cover housing (2) is aligned with the housing (1). By going over the ridge 12c, the open state of the cover housing 2 can be maintained.

Referring to FIG. 14, when the cover housing 2 is in a hard open state, the connector 10 has the curved outer surface of the cover housing 2 in contact with the step of the outer surface of the housing 1, thereby forming the cover housing (10). 2) It can be suppressed from opening too much.
