Description

The present invention relates to a connector used for a mobile phone, a notebook computer, a digital camera, etc., and particularly to a mechanism for pressing a contact against a flexible printed circuit board (hereinafter referred to as "FPC") or a flexible flat cable (hereinafter referred to as "FFC"). It is a thing.

The connector used for mobile phones, CCD cameras, etc. is ultra-thin (so-called light, thin, short, and small) with a narrow pitch, and is mainly composed of a housing, contacts, and slider, and has a structure in which the FPC or FFC is sandwiched between the housing and slider. Is. There are various methods for holding the FPC or FFC between the housing and the slider, but most of them have a structure in which the slider is inserted after the FPC or FFC is inserted into the housing and the FPC or FFC is pressed against the contact.

The housing is provided with a required number of insertion holes into which the contacts are inserted and fitting ports into which the FPC or FFC is inserted.

The contact 64 has a substantially U-shape as shown in FIG. 8, and is mainly composed of a contact portion 22 that contacts the FPC 40 or FFC, a connection portion 24 that connects to a substrate or the like, and a fixing portion 42 that is fixed to the housing 62. Has been done. The contact 64 is fixed to the housing 62 by press fitting or the like.

For example, the slider 66 has a substantially wedge shape as shown in FIG. 8, and after inserting the FPC 40 or FFC into the housing 62 in which the required number of contacts 64 are arranged, the slider 66 is inserted. Such a slider 66 mainly includes a mounting portion 74 mounted on the housing 62 and a pressing portion 68 that presses the FPC 40 or FFC against the contact portion 22 of the contact 64. Before the FPC40 or FFC is inserted, the slider 66 is temporarily attached to the housing 62, and when the slider 66 is inserted after the FPC40 or FFC is inserted, the FPC40 or the slider 66 is inserted as shown in FIG. 8B. The pressing portion 68 of the slider 66 is inserted in parallel with the FFC, and the FPC 40 or the FFC is pressed against the contact portion 22 of the contact 64.

In recent years, there has been an increasing demand for lower profile of this type of connector 60, but in the connector 60 having the above-mentioned structure, as shown in FIG. 8B, there are 6 layers (both sides in the thickness direction of the housing 62). The wall, the thickness of the contact portion 22 and the receiving portion 70 of the contact 64, the thickness of the pressing portion 68 of the slider 66, and the thickness of the FPC 40 or FFC). Considering lowering the doggy style, the receiving portion 70 of the contact 64 is omitted, and five layers (walls on both sides in the thickness direction of the housing 62, the thickness of the contact portion 22 of the contact 64, the thickness of the pressing portion 68 of the slider 66, and the thickness of the pressing portion 68 of the slider 66). Although it is possible to make the structure (thickness of FPC40 or FFC), there is a problem to be solved that the doggy style cannot be further lowered due to the strength and specifications of each part.

Further, in the connector 60 having the above-mentioned structure, the FPC 40 or FFC is inserted and the contact portion 22 of the contact 64 is pressed against the FPC 40 or FFC only on the fitting port 18 side of the housing 62, so that the connector is small. There is also a problem that the workability is worse as it becomes.

Furthermore, when the pitch of the connector 60 is required to be narrowed, there is a limit to the narrowing of the connector if the contact 64 is inserted from one direction as in the conventional structure.

The present invention has been made in view of such conventional problems, and the slider 16 reliably presses the FPC 40 or FFC against the contact portion 22 of the contact 14 without impairing the strength and specifications of each portion. It is intended to provide a connector that can be used, has good workability, and can narrow the pitch and lower the height.

An elastic portion 34 and a fulcrum portion 32 provided between the contact portion 22, the contact portion 22, and the connection portion 24, and a pressing portion 20 and a fulcrum extending from the elastic portion 34 at a position facing the connection portion 24. Another contact portion 22 that comes into contact with the FPC 40 or FFC is also provided in the direction extending from the portion 32. The contact portion 22 (upper side of the drawing of FIG. 2A), the elastic portion 34, the fulcrum portion 32, and the connection portion 24 on the upper side are arranged in a substantially crank shape. The contact portion 22 has a convex shape so as to easily come into contact with the FPC 40 or FFC, and the connection portion 24 is a surface mount type (SMT) as shown in FIG. 1 in this embodiment, but a dip type is also available. good. That is, two contact portions 22, 22 are provided so as to sandwich the FPC 40 or FFC. By providing the contact portions 22 on both sides in the direction perpendicular to the insertion direction of the FPC 40 or FFC, the FPC 40 or FFC is sandwiched between the two contact portions 22, 22 and surely contacts the FPC 40 or FFC. become able to.

The fulcrum portion 32, the elastic portion 34, and the pressing portion 20 are portions for performing the following actions when the FPC 40 or FFC is inserted. After the FPC 40 or FFC is inserted into the fitting port 18 of the housing 12, when the pressing portion 36 of the slider 16 rotates between the connecting portion 24 and the pressing portion 20 of the contact 14, the pressing is performed. The contact portion 22 is pushed up by the pressing portion 36 to use the fulcrum portion 32 of the contact 14 as a fulcrum, and the elastic portion 34 of the contact 14 is tilted toward the contact portion 22 so that the contact portion 22 is on the FPC 40 or FFC side. Is pressed against. The sizes and shapes of the fulcrum portion 32, the elastic portion 34, and the pressing portion 20 are appropriately designed to fulfill such an action.

Further, when a protruding portion 26 is provided at the tip of the pressing portion 20 of the contact 14 and the pressing portion 36 of the slider 16 is rotated between the pressing portion 20 of the contact 14 and the connecting portion 24, the slider 16 rotates. Since the repulsive force against the slider 16 is strong, it is desirable to prevent the central portion of the slider 16 from bulging in the direction of the arrow “b” in FIG. 1 (B). The size of the protruding portion 26 may be any size as long as it can play such a role, and is appropriately designed so that the pressing portion 36 of the slider 16 is caught.

Another contact will be described with reference to FIG. 4 (B). Here, only the difference from the contact 14 described above will be described. The contact portion 22 with the FPC 40 or FFC provided in the extending direction from the fulcrum portion 32 of the contact 141 was deleted, and the shape was substantially inverted h-shaped.

Next, the slider, which is another point of the present invention, will be described. This slider is an electrically insulating plastic, which is manufactured by injection molding of a known technique, and the material is appropriately selected in consideration of dimensional stability, workability, cost, etc., but generally, polybutylene terephthalate (polybutylene terephthalate) Examples thereof include PBT), polyamide (66PA, 46PA), liquid crystal polymer (LCP), polycarbonate (PC), and synthetic materials thereof. The slider 16 mainly has a locking hole 30 in which a shaft 28 portion rotatably mounted on the housing 12, a pressing portion 36 that presses the pressing portion 20 of the contact 14, and a protruding portion 26 of the contact 14 engage with each other. And have. The shaft 28 is a fulcrum for rotating the slider 16, and the slider 16 is rotatably mounted on both sides of the housing 12 in the longitudinal direction. Further, on both sides in the longitudinal direction, lock portions that engage with the housing 12 are provided so that the slider 16 does not lift in the height (upper drawing) direction when the pressing portion 20 of the contact 14 is pressed. Has been done. The shape and size of the lock portion may be any shape as long as it can be engaged with the housing 12, and is appropriately designed in consideration of the above-mentioned role, the size and strength of the connector, and the like.

The pressing portion 36 is a portion to be pressed against the pressing portion 20 of the contact 14, and it is desirable that the pressing portion 36 has an elongated shape, and in this embodiment, it has an elliptical shape. By forming the elliptical shape in this way, the slider 16 is rotated in the direction of the arrow “a” as shown in FIG. 2 (A), and is rotated between the pressing portion 20 and the connecting portion 24 of the contact 14. , The pressing portion 20 of the contact 14 is lifted by the change in the size of the pressing portion 36, and the FPC 40 or FFC is pressed against the contact portion 22 side of the contact 14. The shape of the pressing portion 36 is such that the pressing portion 20 of the contact 14 can be rotated between the pressing portion 20 and the connecting portion 24, and the pressing portion 20 of the contact 14 can be pushed up by a difference in size such as a long axis and a short axis. It may be a thing.

Further, when the slider 16 is rotated, the repulsive force against the rotation of the slider 16 is strong, and the central portion of the slider 16 is prevented from bulging in the direction of the arrow “b” in FIG. 1 (B). Therefore, a locking hole 30 with which the protruding portion 26 of the contact 14 engages is provided separately and independently. By providing the locking holes 30 separately and independently, the strength of the slider 16 is increased and deformation during rotation is prevented.

Finally, the housing will be described. This housing is an electrically insulating plastic, which is manufactured by injection molding of a known technique, and the material is appropriately selected in consideration of dimensional stability, workability, cost, etc., but generally, polybutylene terephthalate (polybutylene terephthalate) Examples thereof include PBT), polyamide (66PA, 46PA), liquid crystal polymer (LCP), polycarbonate (PC), and synthetic materials thereof. The housing 12 is provided with an insertion groove 38 into which a required number of contacts 14 and 141 are mounted, and is fixed by press fitting, hooking (lance), welding, or the like. Further, on both sides in the longitudinal direction, bearing portions on which the shaft 28 of the slider 16 is rotatably mounted are provided. The shape and size of the bearing portion may be any shape as long as the shaft 28 of the slider 16 can be rotated, and the shape and size of the bearing portion are appropriately designed in consideration of this role and the strength and size of the housing 12. Locking portions are provided on both sides in the longitudinal direction at positions corresponding to the locking portions of the slider 16.

Another embodiment of the present invention will be described with reference to FIGS. 5 to 6. The main components are similar to those described above and include a housing, contacts and sliders. The feature of this embodiment is that the two types of contacts 14, 142 are arranged in a staggered pattern by changing the insertion direction into the housing 121, and the pitch is narrowed by arranging the contacts 14 and 142 in a staggered pattern by changing the insertion direction. It corresponds to the lowering of the profile. The housing 121 and the slider 161 are the same as those described above, and one of the contacts 14 is also the same as that of FIG. 4 described above, and the description thereof will be omitted. FIG. 5 is a perspective view of another connector, FIG. 6 (A) is a perspective view of the connector of the present invention cut at the other contact portion with the slider open, and FIG. 6 (B) is a perspective view of the connector in which the FPC is inserted. It is a perspective view of the connector of this invention cut at the other contact part in a state where a slider is closed.

The other contact 142 is also made of metal and is manufactured by press working according to a known technique. The material is the same as that of one contact 14.

Like the one contact 14, the other contact 142 also has two types, a substantially inverted h-shape and a substantially H-shape, and the substantially inverted h-shape is mainly in contact with the FPC 40 or FFC. An elastic portion 34, a fulcrum portion 32, and an elastic portion 34 provided between the connecting portion 24 connected to the portion 22 and the substrate, the fixing portion 42 fixed to the housing 121, the contact portion 22, and the connecting portion 24, and extending from the elastic portion 34. It is provided with the provided pressing portion 20. The contact portion 22, the elastic portion 34, the fulcrum portion 32, and the connection portion 24 are arranged in a substantially U-shape. The substantially H-shaped one is provided with an extension portion 44 extending from the fulcrum portion 32 in the direction opposite to the connection portion 24. The contact portion 22 has a convex shape so as to easily come into contact with the FPC 40 or FFC, and the connection portion 24 is a surface mount type (SMT) as shown in FIG. 5 in this embodiment, but a dip type is also available. good.

Similar to one of the contacts 14, the fulcrum portion 32, the elastic portion 34, and the pressing portion 20 are pressed by the pressing portion 36 of the slider 161 when the FPC 40 or FFC is inserted. When rotating between the receiving portion 20 and the housing 121 or between the pressing portion 20 and the extending portion 44, the pressing portion 20 is pushed up by the pressing portion 36 to push up the fulcrum portion 32 of the contact 142. By using the elastic portion 34 of the contact 142 as a fulcrum and tilting toward the contact portion 22, the contact portion 22 is pressed toward the FPC 40 or the FFC side. The sizes and shapes of the fulcrum portion 32, the elastic portion 34, and the pressing portion 20 are appropriately designed to fulfill such an action.

Further, since a protruding portion 26 is provided at the tip of the pressing portion 20 of the contact 142 and the repulsive force against the rotation of the slider 161 is strong when the pressing portion 36 of the slider 161 is rotated, the central portion of the slider 161 is shown in the drawing. It is desirable to prevent the slider from bulging in the direction of the arrow "C" in 6 (B), but considering the strength of the slider due to the narrowing of the pitch, one of the two types of contacts, the contact 14, It is enough if it is provided. The size of the protruding portion 26 may be any size as long as it can play such a role, and is appropriately designed so that the pressing portion 36 of the slider 161 is caught.

As is clear from the above description, according to the connector of the present invention, the following excellent effects can be obtained.

(1) Since the sliders 16 and 161 are rotated on the contact connecting portion 24 side of the housings 12 and 121 to bring the contact portions 22 of the contacts 14, 141 and 142 into contact with the FPC 40 or FFC, the housing 12 The sliders 16 and 161 are not inserted into the fitting openings 18 of 121, and the connectors 10 and 101 can be lowered by the thickness of the sliders 16 and 161.

Even if the repulsive force against the rotation of the slider 161 is strong when rotating between the sliders 161 it is possible to prevent the central portion of the slider 161 from bulging in the direction of the arrow “b”.

(6) Since the shape of the pressing portion 36 of the sliders 16 and 161 is elongated (there are a long axis and a short axis), when the sliders 16 and 161 are rotated, the contacts 14 and 141 are surely formed. , 142, the pressing portion 20 can be pushed upward, and the contact portion 22 can be easily brought into contact with the FPC 40 or FFC.

(7) The sliders 16 and 161 are provided with locking holes 30 that engage with the required number of protrusions 26 of the contacts 14 and 141, and the locking holes 30 are made independent of each other. The 161 is strong, can be rotated reliably, and does not deform.

(8) If a contact portion 22 that comes into contact with the FPC 40 or FFC is provided in a direction extending from the fulcrum portion 32 of the contact 14, the contact portions are provided on both sides in a direction perpendicular to the insertion direction of the FPC 40 or FFC. Since 22 is provided and the FPC 40 or FFC is sandwiched between the contact portions 22 and 22, the FPC 40 or FFC can be reliably contacted.

(9) If a contact portion 22 that contacts the FPC 40 or FFC is provided between the fulcrum portion 32 and the connection portion 24 of the other contact 142, both sides in a direction perpendicular to the insertion direction of the FPC 40 or FFC will be provided. Since the contact portion 22 is provided and the FPC 40 or FFC is sandwiched between the contact portions 22 and 22, the FPC 40 or FFC can be reliably contacted.
