Description

  The present invention relates to a connector used for a mobile phone, a notebook personal computer, a digital camera, and the like. In particular, the connector is narrowed when there are contact portions on both sides of a flexible printed circuit board (hereinafter referred to as “FPC”). Is.

Connectors used for cellular phones, CCD cameras, and the like are very thin (so-called light thin short) at a narrow pitch, and mainly include a housing and a contact, and an FPC is inserted into the housing to contact the contact portion of the contact. It has a structure, mainly a housing, a contact, and a slider, and the FPC is sandwiched between the housing and the slider. There are various methods for holding the FPC between the housing and the slider. However, there are many methods in which the FPC is inserted into the housing and then the slider is inserted and the FPC is pressed against the contact. In addition, in order to achieve customer specifications and narrow pitches, the contact connection portion may have to be arranged on the fitting port side of the housing.
The housing is provided with a required number of insertion holes into which the contacts are inserted and a fitting port into which the FPC is inserted.
The contact is mainly composed of a contact portion that comes into contact with the FPC, a connection portion that is connected to a substrate and the like, and a fixed portion that is fixed to the housing. This contact is fixed to the housing by press fitting or the like.
For example, Japanese Utility Model Publication No. 6-60983 is available as a zero insertion force structure. According to the summary of Japanese Utility Model Laid-Open No. 6-60983, the object is related to a connector for a printed circuit board with a slider used in a narrow space in an electronic device or a communication device. A U-shaped arm portion fixed on the front side is formed as an insertion guide to the housing into which the slider is inserted, and a convex portion is provided on the open end side of the U-shaped arm portion. A notch is provided so that the open end of the arm can be seen from the insertion direction, and a protruding part having an inclined surface that engages the convex part of the slider is provided on both side ends of the housing, and the slider is connected to the flexible printed circuit board. When the slider is inserted into the housing together with the terminal portion, the protruding portion of the slider gets over the protruding portion having the inclined surface of the housing. U-shaped open end of the arm portion of the shape is expanded outwardly temporarily and connector open end upon completion of insertion was made to return to the normal position is disclosed. The so-called piano touch structure is disclosed in Japanese Patent Application Laid-Open No. 13-257020 for the purpose of surely aligning the contact of the connector and the FPC or FFC pattern, on the opening side where the FPC or FFC is inserted. The protrusions are arranged on the ridge line between the contacts of the connector terminal block, the FPC or FFC is inserted into the terminal block, and the slider is moved to press the FPC or FFC against the contact, When the FPC or FFC is pressed against the contact with the slider and electrically connected, the protrusion enters the recess between the FPC or FFC patterns, thereby ensuring alignment between the connector contact and the FPC or FFC pattern. What to do is disclosed. According to the summary of JP-A-5-326084, with respect to a circuit board connector, there is no occurrence of misalignment or the like even in a circuit board in which the signal input / output terminals along the end pieces are adjacent to each other and the terminals themselves are particularly narrow. For the purpose of improving the productivity by reliably connecting, the reference 3 discloses a jack terminal individually connected to a plurality of signal input / output terminals formed in several rows on the edge of the circuit board. After the circuit board is inserted from the signal input / output terminal forming side into the jack terminal contact side opening of the insulator planted at a position corresponding to the input / output terminal, the circuit board is connected to the jack terminal contact side. A circuit board connector for connecting a corresponding contact and a signal input / output terminal by pressing and moving to a circuit when the insulating circuit board is inserted to a predetermined position. What constitutes comprises means capable of positioning at least the width-direction edges of the signal input-output terminal forming region a plate is disclosed.

In recent years, with this type of connector, with the miniaturization of electrical equipment (electronic equipment), the demand for further miniaturization has become stronger, and the demand for narrow pitch has become stronger, while at the same time increasing the signal density of FPC. It has become necessary to provide contact portions on both sides.
However, the connector having the above-described structure has a problem that it cannot cope with an FPC having contact portions on both surfaces and cannot cope with a narrow pitch.
That is, in the ZIF type as disclosed in Reference 1, the FPC is inserted into the housing, and then the FPC is pressed against one side by the slider to come into contact with the contact. (It can only be pressed against one side.) Further, even in the so-called piano touch type in which the slider is rotated on the FPC insertion side of the housing as in Reference 2, the FPC is pressed against one side by the slider and is brought into contact with the contact as in the ZIF type. , FPCs with contact parts on both front and back sides cannot be supported (can only be pressed against one side).

  The present invention has been made in view of such a conventional problem, and it is an object of the present invention to provide a connector that can cope with narrowing of the pitch and can accommodate FPCs having contact portions on both sides.

  The above-described object is a connector that is detachably fitted to an FPC, and includes a required number of contacts having a contact portion that comes into contact with the FPC, and a fitting port into which the FPC is inserted while the contacts are held and fixed. In the connector including the housing having the FPC, when there are contact portions on both the front and back surfaces of the FPC, two types of contacts are used, and when one contact is inserted from the opposite side of the fitting opening of the housing, the contact portion of the contact is the FPC. The other contact is inserted from the fitting opening side of the housing, and the contact portion of the contact comes into contact with the contact portion on the back surface of the FPC.

Two types of contacts are paired, the contact portions of the pair of contacts are arranged to face each other, and the FPC is sandwiched between the pair of contacts. Thus, by sandwiching the FPC between the contact portions of a pair of contacts, the contact portion of the upper contact comes into contact with the contact portion on the surface side of the FPC, and the contact portion of the lower contact comes into contact with the FPC. Contact the contact part on the back side.
It arrange | positions so that the contact part of a pair of contact may become zigzag in a longitudinal direction. By arranging in a zigzag manner in this way, a narrower pitch can be achieved.
The housing is provided with a recess for inviting the flexible printed circuit board on the fitting port side, and the other connecting portion of the contact is disposed so as not to protrude from the recess of the housing. By doing so, the FPC can be easily guided into the fitting opening of the housing.

In order to obtain a zero insertion force (ZIF) structure in which no force is applied when the flexible printed circuit board is inserted into the fitting opening of the housing, a slider that is pressed against the contact after the flexible printed circuit board is inserted is used. By adopting the ZIF structure in this way, the FPC can be easily inserted into the fitting opening of the housing, and can be reliably connected to the contact portions on both the front and back surfaces of the FPC.
One contact is provided with an elastic part and a fulcrum part between the contact part and the connection part, and the contact part, the elastic part, the fulcrum part and the connection part are arranged in a substantially crank shape, and A holding portion extending from the elastic portion is provided at a position facing the connection portion, and the other contact has a contact portion and a connection portion, and is arranged so that the connection portion enters the recess of the housing. The slider is provided with a pressing portion continuously provided in the longitudinal direction, and the pressing portion is rotated between the connecting portion of one contact and the pressing portion so that the pressing portion is rotatable. Install in the housing. Thus, by rotating the slider on the side opposite to the fitting port side of the housing, the contact is pressed against the FPC. Therefore, the FPC having contact portions on both the front and back surfaces can be handled. Can contact.

  As an operation of the present application, after the FPC is inserted into the fitting opening of the housing, the pressing portion of the slider rotates between the connecting portion of one of the contacts and the pressing portion. Is pushed up by the pressing portion so that the fulcrum portion of one of the contacts serves as a fulcrum, and the elastic portion of one of the contacts is inclined toward the contact portion, whereby the contact portion of one of the contacts is on the surface side of the FPC And the other contact is pressed against the back side of the FPC.

As is clear from the above description, according to the connector 10 of the present invention, the following excellent remarkable effects can be obtained.
(1) When there are contact portions 52, 52 on both front and back surfaces of the FPC 22, two types of contacts 14, 16 are used, and one of the contacts 14 is inserted from the opposite side of the fitting port 24 of the housing 12, and the contact 14 The contact portion 30 contacts the contact portion 52 on the front surface of the FPC 22, and the other contact 16 is inserted from the fitting port 24 side of the housing 12, and the contact portion 20 of the contact 16 is the contact portion 52 on the back surface of the FPC 22. Therefore, the FPC 22 having the contact portions 52, 52 on both the front and back surfaces can be easily handled, the size can be reduced, and the signal density can be increased.
(2) Two types of contacts 14 and 16 are paired, the contact portions 30 and 20 of the pair of contacts 14 and 16 are arranged to face each other, and the FPC 22 is sandwiched between the pair of contacts 14 and 16. Therefore, the contact portion 30 of one of the contacts 14 comes into contact with the contact portion 52 on the front surface side of the FPC 22, and the contact portion 20 of the other contact 16 easily contacts the contact portion 52 on the back surface side of the FPC 22. Can touch.
(3) When the contact portions 52, 52 provided on both front and back surfaces of the FPC 22 are arranged in a staggered manner in the longitudinal direction, the contact portions 30, 20 of the pair of contacts 14, 16 are staggered in the longitudinal direction. Accordingly, the pitch can be further reduced, the signal density can be increased, and the positions of the contact portions 52 and 52 of the FPC 22 can be easily handled.
(4) The housing 12 is provided with a concave portion 26 that invites the FPC 22 on the fitting opening 24 side, and the other connection portion 34 of the contact 16 is disposed so as not to protrude from the concave portion 26 of the housing 12. Therefore, the FPC 22 can be reliably guided to the fitting port 24 of the housing 12.
(5) In order to obtain a zero insertion force (ZIF) structure in which no force is applied when the FPC 22 is inserted into the fitting port 24 of the housing 12, a slider 18 that presses against the contact 14 after the FPC 22 is inserted is provided. Since it is used, the FPC 22 can be easily inserted into the fitting port 24 of the housing 12, and can be reliably connected to the contact portions 52, 52 on the front and back surfaces of the FPC 22.
(6) One contact 14 is provided with an elastic part 40 and a fulcrum part 38 between the contact part 30 and the connection part 34, and the contact part 30, the elastic part 40, the fulcrum part 38, and the connection part 34. Are arranged in a substantially crank shape, and a pressing portion 32 extending from the elastic portion 40 is provided at a position facing the connection portion 34, and the other contact 16 is formed of the contact portion 20 and the connection portion 34. And the connecting portion 34 is disposed so as to enter the concave portion 26 of the housing 12, and a pressing portion 50 is provided continuously to the slider 18 in the longitudinal direction, and the pressing portion 50 is a connecting portion of one contact 14. Since the slider 18 is mounted on the housing 12 so that the pressing portion 50 rotates between the pressing portion 34 and the pressing portion 32, the housing 12 has a side opposite to the fitting port 24 side. in front By rotating the slider 18, the contact 14 is pressed against the FPC 22, so that the FPC 22 having the contact portions 52, 52 on both the front and back surfaces can be dealt with, and the contact portions 52, 52 of the FPC 22 are surely provided. Can contact.
(7) Since the slider 18 is rotated on the contact connecting portion 34 side of the housing 12, the contact portions 30, 20 of the two types of contacts 14, 16 are brought into contact with the FPC 22. Thus, the slider 18 can be lowered by the thickness of the slider without inserting the slider 18 in 24.

An important feature of the present invention is that "when there are contact portions on both the front and back sides of the FPC, two types of contacts are used, and when one contact is inserted from the opposite side of the fitting opening of the housing, the contact portion of the contact is It is in contact with the contact portion on the front surface of the FPC, and the other contact is inserted from the fitting opening side of the housing and the contact portion of the contact is in contact with the contact portion on the back surface of the FPC. There are two types of forms that take advantage of this feature. The two types are the same in that the FPC is in contact with the contact, but there is a difference in how the FPC is in contact with the contact.
The connector having the first structure mainly includes a housing, a contact, and a slider. The connector rotates and presses the FPC against the contact, and is a so-called piano touch type connector. . The position for rotating the slider is the contact connection side (tail side). In the following examples, this type will be described in detail.

The connector having the second structure mainly includes a housing and a contact, and is a type in which the FPC is inserted into a fitting opening of the housing and the FPC is brought into contact (pressed) with the contact. It is called a so-called NON ZIF type connector that does not use the connector. That is, the FPC is forcibly inserted between the contact contact portions or between the contact and the housing, which is narrower than the thickness of the FPC, and is brought into contact (pressed) with the contact.
Both of the two structures described above use two types of contacts, so that the contact portion of one contact is in contact with the contact portion on the front surface of the FPC, and the contact portion of the other contact is in contact with the contact portion on the back surface of the FPC. Needless to say, I did.

Further, the housing 12 is provided with a fitting port 24 into which the FPC 22 is inserted, and a concave portion 26 for inviting the FPC 22 is provided on the fitting port 24 side. Considering the strength of the housing 12, the connectivity (solderability) of the contact 16, and the ease of inviting the FPC 22, the size of the recess 26 is determined so that the connection portion 34 of the contact 16 is the recess 26 of the housing 12. It is appropriately designed so as not to protrude from the inside. The size of the fitting port 24 is appropriately designed so that the FPC 22 can be inserted and can be pressed against the contacts 14 and 16 by the slider 18 when the FPC 22 is inserted. On both sides of the housing 12 in the longitudinal direction, bearing portions to which the shaft 46 of the slider 18 is rotatably mounted are provided. The shape and size of the bearing portion may be any as long as the shaft 46 of the slider 18 is mounted so as to be rotatable, and is appropriately designed in consideration of this role and the strength and size of the housing 12. Furthermore, on both sides in the longitudinal direction, locking portions are provided at positions corresponding to the lock portions of the slider 18.

  Next, the two types of contacts 14 and 16 which are the points of the present invention will be described. The two types of contacts 14 and 16 are made of metal and are manufactured by a known press working. As the material of the contacts 14 and 16, spring property, conductivity and the like are required, and examples thereof include brass, beryllium copper, and phosphor bronze.

  One of the contacts 14 has a substantially h-shaped shape as shown in FIG. 4A, and mainly has a contact portion 30 that contacts the FPC 22, a connection portion 34 that is connected to the substrate, and a fixing portion 36 that is fixed to the housing 12.
