Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention connects a flat flexible cable (including what is called FPC, FFC, etc .; hereinafter simply referred to as FPC) to other equipment such as a printed circuit board. TECHNICAL FIELD The present invention relates to a flat flexible cable connector effective as a technology.

[0002]

2. Description of the Related Art Conventionally, the following method has been known as a method for connecting an FPC and a printed circuit board. A method in which a connecting end portion of an FPC is connected to a plug connector, a receptacle connector is mounted on a printed circuit board, and the plug connector and the receptacle connector are fitted (connected) to each other. See, for example, JP-A-8-203626.

As another method, there is known a method of mounting a connector on a printed circuit board and electrically connecting by exposing a conductor exposed at a connection end of an FPC to a contact of the connector on the printed circuit board. Has been.

The connection method using the plug connector and the receptacle connector requires a plug connector for connecting the FPC, which increases the manufacturing cost and makes it difficult to miniaturize the receptacle connector mounted on the printed circuit board. However, there is a problem that there is a limit in reducing the mounting area.

Further, the method in which the conductive portion itself of the FPC is directly pressed against the contact of the connector mounted on the printed circuit board has the following problems. When the printed circuit board or the connector itself warps, the connection end of the FPC is lifted from the contact, which makes it difficult to secure reliable connection at all poles. This problem becomes remarkable especially when the number of poles is large.

In this respect, Japanese Patent Laid-Open No. 11-111401 discloses a connection technique devised so that the area occupied by equipment such as a printed circuit board can be reduced, the reliability of the connection can be ensured, and the manufacturing cost can be reduced. Is proposed.

This adopts the following concept. By forming a slit in the connection end of the FPC, the conductor exposed portion of the FPC is bent to one side of the connection end to form a pair of connection pieces. A backup material (reinforcing material) is attached between both connecting pieces to hold both connecting pieces from the inside, and the backup material is taped to the FPC.
Then, the connector on the FPC side is configured. And
By providing a mating connector having a fitting portion into which the connecting piece of this connector is inserted on the printed circuit board side, both are electrically connected.

[0008]

As described above, even in the improved existing technology, there are problems to be solved in the following points. First, it is about miniaturization and thinning that are necessary to make the occupied area as small as possible. FPC
When the side connector is inserted into and mated with the mating connector, a locking means is usually required to prevent the connector from coming off.
However, this locking means greatly hinders downsizing and thinning of the connector.

For example, as described in Japanese Patent No. 3079463, the ratio of the lock metal fittings provided on both sides of the connector is large, and there is a problem that it is difficult to further reduce the size and thickness. Further, as described in Japanese Utility Model Laid-Open No. 4-91071, the reinforcing metal fitting of the receptacle connector mounted on the circuit board has the same problem as the lock metal fitting. Especially, when both the lock fitting and the reinforcing fitting are provided, such a problem becomes remarkable.

Secondly, when a lock fitting is provided on a connector having a small terminal pitch due to downsizing and thinning, there is a risk that contacts may drop out or short-circuit between poles within the movable range of the lock fitting. This tends to occur particularly when the lock fitting is displaced in the pitch direction of the terminals.

Thirdly, in the conventional connector, the impact or prying force at the time of connecting the plug connector to the receptacle connector is easily transmitted directly to the soldering portion of the reinforcing metal fitting. Therefore, solder cracks or peeling may occur.

The object of the present invention is to reduce the occupied area on equipment such as a printed circuit board as much as possible and to improve the manufacturability to reduce the manufacturing cost.
By devising the movable direction of the lock piece, it is possible to provide a technology for a connector for a flat type flexible cable that prevents the risk of contact dropout and short circuit between poles, and also has a function of mitigating impact on the reinforcing metal fitting.

[0013]

A connector for a flat type flexible cable according to the present invention comprises a plug connector provided on the flat type flexible cable and a receptacle connector mounted on a circuit board. The plug connector includes a connecting piece formed by processing a portion in which a flat flexible cable and a metal shell plate are bonded together. The receptacle connector includes a housing having a receiving portion for receiving the connecting piece, terminals arranged in the receiving portion and contacting the connecting piece, and reinforcing metal fittings attached to both ends of the housing for fixing the housing to a circuit board. With. The reinforcing metal member is provided with a lock piece that engages with the connection piece and holds the contact state between the connection piece and the terminal.

According to the present invention, since the lock piece is provided on the reinforcing metal fitting, the reinforcing metal fitting and the lock metal fitting can be combined into one, and the number of parts can be reduced, and the receptacle connector can be made smaller and thinner. As a result, the occupied area on the equipment such as the printed circuit board can be made as small as possible, and the manufacturability can be improved to reduce the manufacturing cost. Another object of the present invention is to provide a technique for a flat type flexible cable connector that also has a shock absorbing function for reinforcing metal fittings.

The connecting piece comprises two connecting pieces facing each other which are arranged at intervals in the longitudinal direction of the flat type flexible cable, and the conductor exposed portions of the flat type flexible cable are provided on the facing surfaces of the connecting pieces. It is desirable to be located. By positioning the exposed conductors on the surfaces (insides) of the two connecting pieces that face each other, both supporting pieces are positioned outside. as a result,
Since there is no shell plate between the exposed pieces, the distance between the exposed pieces (width of the connector) can be made as small as possible. Therefore, also from this point, the structure can be easily reduced as a whole.

It is desirable that the lock piece is configured to be displaceable in the length direction of the flat flexible cable by the elasticity of the lock piece itself. By displacing the lock piece in the length direction of the flat flexible cable, that is, by devising the movable direction of the lock piece so as to be displaced in the direction orthogonal to the pitch direction of the terminals, contact loss and short circuit between poles can be prevented. Danger can be prevented.

It is preferable that the connecting piece is provided with a concave portion, and the lock piece is provided with a convex portion that fits into the concave portion of the connecting piece. With this configuration, the locking function can be exerted by the concave-convex fitting, and the configuration can be simple.

The connecting piece is cut and raised from the flat flexible cable, and the exposed piece has conductor exposed portions formed on opposite surfaces of the connection pieces, and the shell plate is cut and raised and is provided on the opposite side of the exposed conductor portion. A support piece for supporting the surface is preferably provided, and a recess is provided on the outer surface of the support piece. By forming the supporting piece from the laminated material of the flat type flexible cable and the shell plate, it becomes possible to secure the necessary strength and to easily reduce the overall size and thickness. Since the concave portion into which the convex portion fits is provided on the support piece made of metal, it exhibits durability against wear due to concave-convex fitting.

It is preferable that the exposed piece and the support piece are attached to each other with an adhesive, and the tip of the support piece projects toward the receptacle connector side more than the tip of the exposed piece. In this way, by projecting the support piece longer than the exposed piece, the tip of the exposed piece can be protected by the tip of the support piece.

The terminal is provided with a raised portion that comes into contact with the exposed conductor portion, and the raised portion and the convex portion of the lock piece are set at positions relatively displaced in the insertion direction of the connection piece with respect to the receiving portion. Is desirable. By setting in this way, the positional relationship between the raised portion and the convex portion is displaced in the insertion direction of the connection piece. Therefore, the timing when the raised portion of the terminal contacts the exposed piece and the timing when the convex portion contacts the support piece are deviated. As a result, it is possible to reduce the resistance when the connecting piece is inserted into the receiving portion and the resistance when the connecting piece is pulled out at the time of connecting the connector. That is, it is possible to enhance operability while exhibiting a reliable connection function and a lock function.

The reinforcing metal member has a body portion curved in an inverted U shape having a function of positioning the plug connector with respect to the receptacle connector, and the lock piece extends from one of two opposing pieces of the body portion and the other piece. Is preferably projected from the housing and soldered to the circuit board. In this case, the other piece is soldered to the circuit board, and the lock piece extends from the one piece that has become free, so that a portion that is easily elastically deformed is formed in the inverted U-shaped main body portion. The inverted U-shaped main body portion absorbs the impact from the lock piece and functions so as not to cause cracks or peeling in the soldered portion.

An end protrusion is provided at the tip of the support piece so as to protrude toward the receptacle connector side from the tip of the exposed piece. The end protrusion comes into contact with the lock piece and is grounded when the connector is connected. It is desirable that it is set as follows. In this way, when the end protruding portion of the tip of the support piece is made to protrude toward the receptacle connector side from the tip of the exposed piece,
When the connector is connected, the support piece and the lock piece can be first brought into contact with each other and electrically connected to the grounded lock piece. Therefore, this relationship can be utilized for improving the durability due to contact between metals and for preventing static electricity of the connector.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on the embodiments shown in the drawings. FIG. 1 is a plan view of a plug connector provided on a flat flexible cable. 2 and 3 are sectional views of the plug connector, FIG. 4 is a sectional view of the receptacle connector, and FIG. 5 is a plan view of the receptacle connector.
FIG. 6 is a sectional view of the receptacle connector. In this embodiment, an example in which the present invention is applied to a connector that connects an FPC and a printed circuit board is shown.

In these figures, 1 is an FPC,
2 is a printed circuit board. A simple plug connector 10 is formed on the FPC 1. A receptacle connector 20 to which the plug connector 10 is connected is mounted on the printed circuit board 2. Plug connector 10
The receptacle connector 20 and the receptacle connector 20 form a flat flexible cable connector CN according to the present invention (see FIGS. 7 and 8).

The plug connector 10 is provided with a connecting piece 11 formed by processing a portion where the FPC 1 and the metal shell plate 3 are bonded together (FIGS. 3 and 7).
reference). The connecting piece 11 is a portion to be inserted into the receiving portion 21 of the mating connector (receptacle connector) 20, and has a function for electrically connecting.

The connection piece 11 is cut out from the FPC 1 and has an exposed conductor portion 12a formed on one surface thereof.
And a support piece 13 that is cut and raised from the shell plate 3 and supports the surface of the exposed piece 11 opposite to the one surface. The FPC 1 and the shell plate 3 are attached to each other via an adhesive (not shown). Therefore, the exposed piece 12
The support piece 13 and the support piece 13 are also bonded and integrated with each other via an adhesive. Consider the heat resistance of the connector for the adhesive,
For example, a thermosetting adhesive is used.

Although the height of the connecting piece 11 depends on the thickness and size of the FPC 1, it is set to about 1 mm in this embodiment. The thickness of the FPC 1 is considerably thin as shown in FIG. 7, and is excellent in flexibility. Therefore, FPC
Even if only the exposed piece 12 from 1 is cut and raised, it is difficult to make it stand alone. Therefore, the shell plate 3 is provided with a support piece 13 for supporting the exposed piece 12. Therefore, the support piece 13 has a reinforcing function for giving rigidity to the FPC 1.

The connecting piece 11 of the plug connector 10 is an FP
Two pieces are arranged at intervals in the longitudinal direction of C1. Therefore, the plug connector 10 includes two connecting pieces 11 and 11 facing each other. And both connection pieces 11,
The conductor exposed portions 12a and 12a are located on the surfaces of the conductors 11 facing each other. As shown in FIG. 7, the exposed conductor portion 12a is
The conductor 1b is exposed by removing a part of the insulating coating 1a that covers one surface of the FPC 1. Of course, the conductor exposed portion 12a can be formed in advance when the FPC 1 is manufactured. Therefore, it is preferable to adopt this method in consideration of manufacturability.

On the surface of the support piece 13 to be bonded to the exposed piece 12, an inclined surface 13b for forming a tapered surface 12b by inclining the tip end portion of the exposed piece 12 toward the support piece 13 side is formed. The protruding size of the support piece 13 is set to be longer than the protruding size of the exposed piece 12.
In the example shown in FIG. 7, the slope 13b is formed by a part of the V-shaped groove, and the tip of the exposed piece 12 is fitted into the groove. Thereby, the tip of the exposed piece 12 is designed so as not to project from the tip of the support piece 13.

On both sides (corresponding to the width direction of the FPC) of the support piece 13, only the both sides are provided with the receptacle connector 20.
End projections 13c, 13c that are projected in the insertion direction are formed. The end protrusions 13c and 13c have a function of preventing static electricity, which will be described later, and the receptacle connector 2
The insertion guide function of the plug connector 10 for 0 is also demonstrated.

In the embodiment, as shown in FIG. 1, an expansion region 1c widened in the width direction is formed in the middle of the FPC 1 in the length direction (near the end). This is FP
Since the wiring density related to the number of conductors of C1 is high, the distance between the conductors 1b and the width of the conductor 1b itself can be widened. This improves connection reliability and manufacturability.

The receptacle connector 20 mounted on the circuit board 2 includes a housing 22 having a receiving portion 21 for receiving the connecting piece 11, a terminal 23 arranged in the receiving portion 21 and contacting the connecting piece 11, and a housing. Reinforcing metal fittings 24 are attached to both ends of the wiring board 22 to fix the housing 22 to the circuit board 2. The reinforcing metal piece 24 is provided with a lock piece 25 that engages with the connection piece 11 and holds the contact state between the connection piece 11 and the terminal 23.

As shown in FIGS. 5 and 6, the housing 22 is substantially rectangular in plane and is formed to have a height of about 1 mm. A partition 22a is provided at the center of the housing 22.
Are provided on both sides of the partition 22, and the groove-shaped receiving portions 2
1, 21 are formed. Then, each receiving portion 21, 2
A large number of terminals 23 are arranged along 1 (arranged in two rows), and the contact pieces 23b of the terminals 23 are arranged in a standing state in the receiving portions 21 and 21.

The fixing portion 23c of each terminal 23 is the housing 2
It is fitted in the terminal mounting groove of 2. Also, each terminal 2
3 is provided with a solder tail 23d extending downward from the fixed portion 23c, and is soldered to the circuit board 2.

At both ends of the housing 22, lock pieces 2 are provided.
Groove portions 21a, 2 for mounting the reinforcing metal fitting 24 with 5
1a is formed. The groove portions 21a, 21a form one groove-shaped portion continuously with the receiving portions 21, 21.
Therefore, the groove-shaped portion is formed in a rectangular frame shape as a whole as a whole.

The reinforcing metal fitting 24 is shown in FIGS. 5, 6 and 10.
As shown in (a), (b), and (c), the main body 24a is curved in an inverted U shape. The body portion 24a also has a positioning function of the plug connector 10 with respect to the receptacle connector 20. The positioning function of the body portion 24a is mainly performed in the length direction of the plug connector 10 (FPC1
(Corresponding to the width direction of) is set.

One piece 2 of the two opposite pieces of the main body 24a
A lock piece 25 extends from 4b, and the other piece 24c projects from the housing and is soldered to the circuit board 2. The other piece 24c is longer than the one piece 24b, and its end is formed as a solder tail 24d.

The lock piece 25 is configured to be displaceable in the length direction of the FPC 1 by the elasticity of the lock piece 25 itself. In this way, the displacement direction (movable direction) of the lock piece 25
By devising the above, it is possible to prevent the risk of contact loss and short circuit between poles due to misalignment when locking (connecting the connector). The length direction of the FPC 1, which is the displacement direction of the lock piece 25, corresponds to the direction orthogonal to the arrangement pitch direction of the terminals 23.

By setting the displacement direction of the lock piece 25 to be a direction orthogonal to the arrangement pitch direction of the terminals 23, the lock piece 2
This is because it is possible to prevent the contact state between the terminal 23 and the connection piece 11 from being affected when the operation of 5 is performed. Let us consider a case where the displacement direction of the lock pieces 25 is the arrangement pitch direction of the terminals 23.

When the lock piece 25 is operated (displaced), a force acts to move the plug connector 10 in the width direction of the FPC 1. Because this force is in the pitch direction of the terminals 23, it is a force that displaces the normal contact state between the terminals 23 and the connection piece 11 in the direction of short-circuiting between the electrodes.

The connecting piece 11 of the plug connector 10 is provided with a recess (circular hole) 13h, and the lock piece 25 has
A convex portion 25a that fits into the concave portion 13h of the connection piece 11 is provided. Thereby, the lock mechanism of the connection piece 11 is configured. In this way, the simple structure is employed in which the locking function is exerted by the concave and convex fitting.

The recess 13h is provided on the outer surface of the support piece 11. The concave portion 13h into which the convex portion 25a is fitted is provided on the support piece 13 made of metal, so that durability can be exhibited against wear due to concave-convex fitting.

In this embodiment, as shown in the figure, the exposed piece 12 and the support piece 13 are bonded together with an adhesive, and the end projections 13c, 13c at the tip of the support piece 13 are exposed.
It projects toward the receptacle connector 20 side from the tip of No. 2. By projecting the end protrusions 13c, 13c of the support piece 13 toward the receptacle connector 20 side from the tip of the exposed piece 12, the support piece 13 and the lock piece 2 can be connected at the time of connector coupling.
No. 5 can be contacted first. This relationship can be used for improving durability due to contact between metals and for preventing static electricity of the connector.

The terminal 23 is provided with a raised portion 23a which comes into contact with the conductor exposed portion 12a. The raised portion 23a and the convex portion 25a of the lock piece 25 are set at positions relatively displaced in the insertion direction of the connection piece 11 with respect to the receiving portion 21.
By setting in this way, the raised portion 23a and the convex portion 25a
The positional relationship of is shifted in the insertion direction of the connecting piece 11.

Therefore, the timing at which the raised portion 23a of the terminal 23 comes into contact with the exposed piece 12 and the projection 25a on the support piece 13
The timing of contact with is deviated. As a result, it is possible to reduce the resistance when the connecting piece 11 is inserted into the receiving portion 21 and the resistance when the connecting piece 11 is pulled out when the connectors are connected.
That is, it is possible to enhance operability while exhibiting a reliable connection function and a lock function.

According to this embodiment, since the reinforcing metal fitting 24 is provided with the lock piece 25, the reinforcing metal fitting 24 and the lock metal fitting are integrated into one, and the number of parts is reduced, and the receptacle connector 20 is made smaller and thinner. Can be achieved. As a result, the occupied area on the equipment such as the printed circuit board 2 can be made as small as possible, and the manufacturability can be improved to reduce the manufacturing cost. Furthermore, reinforcement metal fittings 2
It is possible to obtain the technology of a flat type flexible cable connector that also has an impact mitigation function. The shock absorbing function of the reinforcing metal member 24 is exerted extremely effectively because it is generated by the synergistic effect of the elasticity of the main body portion 24a having a U-shaped cross section and the elasticity of the lock piece 25 extending therefrom.

The connecting piece 11 to the receptacle connector 20 is formed by processing the portion where the FPC 1 and the shell plate 3 are bonded together, and the exposed piece 12 and the supporting piece 1 are formed.
3 and 3 are integrated via an adhesive. Therefore, the plug connector 10 is made of a so-called two-layer laminate material (FPC and shell plate 3). As a result, it is possible to reduce the size and thickness of the conventional connector that is configured by assembling a plurality of separate components.

Further, the end projecting portion 13 at the tip of the supporting piece 13
By causing c and 13c to project beyond the tip of the exposed piece 12, the tip of the support piece 13 is first placed in the receptacle connector 2
Since 0 is touched, this relationship can be used as a countermeasure against static electricity. That is, by providing a circuit configuration in which the shell plate 3 on which the support piece 13 is formed is grounded, it is possible to provide a countermeasure against static electricity for charging the FPC 1 and the printed circuit board 2.
