Description

  The present invention relates to a connector used in a mobile phone, a notebook computer, a digital camera, etc., and in particular, contacts a connection object of a flexible printed circuit (hereinafter referred to as "FPC") or a flexible flat cable (hereinafter referred to as "FFC"). Relates to a mechanism for pressing the

  Connectors used for mobile phones, CCD cameras, etc. are narrow pitch and ultra thin (so-called light, thin, short and small), and are mainly composed of a housing, contacts, and a slider, and a structure in which FPC or FFC is held between the housing and the slider. It is. Various methods can be considered for holding the FPC or FFC with the housing and the slider, but among them, the structure in which the FPC or FFC is inserted into the housing and then the slider is inserted 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 an insertion port into which the FPC or FFC is inserted.

  The contact 64 is substantially U-shaped as shown in FIG. 8 and is mainly composed of a contact portion 22 in contact with the FPC 40 or FFC, a connection portion 24 connected to a substrate or the like, and a fixing portion 42 fixed to the housing 62. It is 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 the FFC into the housing 62 in which the required number of contacts 64 are disposed, the slider 66 is inserted. Such a slider 66 mainly includes a mounting portion 74 (FIG. 7) mounted to the housing 62 and a pressing portion 68 for pressing the FPC 40 or the FFC against the contact portion 22 of the contact 64. Before the FPC 40 or FFC is inserted, the slider 66 is temporarily attached to the housing 62. When the slider 66 is inserted after the FPC 40 or FFC is inserted, as shown in FIG. The pressing portion 68 of the slider 66 is inserted in parallel to the FFC, and the FPC 40 or the FFC is pressed to the contact portion 22 of the contact 64.

  In recent years, this type of connector 60 has been required to have a lower profile. However, in the connector 60 having the above-described structure, six layers (both sides in the thickness direction of the housing 62 as shown in FIG. The thickness of the contact portion 22 of the wall / contact 64 and the thickness of the receiving portion 70, the thickness of the pressing portion 68 of the slider 66, and the thickness of the FPC 40 or the FFC. In view of lowering the height, the receiving portion 70 of the contact 64 is omitted, and the thickness of the pressing portion 68 of the slider 66 of the five layers (thickness direction both sides of the housing 62 and the contact portion 22 of the contact 64) Although the thickness of the FPC 40 or the FFC can be made, there is a problem to be solved that the height can not be further reduced due to the strength and specifications of each part.

  In the connector 60 having the above-described structure, the insertion of the FPC 40 or the FFC and the operation of pressing the contact portion 22 of the contact 64 against the FPC 40 or the FFC are performed only on the fitting opening 18 side of the housing 62. There is also a problem that the more you work, the worse the work efficiency.

  Furthermore, when it is required to narrow the pitch of the connector 60, there is a limit to narrowing the connector if the contacts 64 are inserted from one direction as in the conventional structure.

  The present invention has been made in view of such conventional problems, and the slider is operated to reliably contact the connection object of the FPC or the FFC without damaging the strength or the specification of each part.

This contact is made of metal and is produced by means of pressing in accordance with the known art. As the material of the contact, since springiness and conductivity etc. are required, brass, beryllium copper, phosphor bronze and the like can be mentioned.

The connector 10 of the embodiment includes a required number of contacts, and the required number of contacts are configured to include the first contacts 14 or configured to include the first contacts 14 and the second contacts 142, as shown in FIG. In the connector 10 shown in FIG. 4, all the required number of contacts are constituted by the first contacts 14 shown in FIG.
The first contact 14 is located on the side of the insertion opening 18 of the housing 12 and is located on the opposite side of the FPC or FFC connection target (FPC in FIG. 2B) 40 to the substrate mounting surface (not shown). Between the first contact portion 22a and the first connection portion 24a, the first connection portion 24a being able to contact the surface 40a to be formed, the first connection portion 24a located on the side where the slider 16 is located and surface mounted on the substrate The first connecting portion 34a located on the side opposite to the insertion port 18, the first pressing portion 20a located on the side opposite to the side where the slider is located and pressed by the slider 16, and the opposite side to the first connecting portion 24a And the first connecting portion 22a, the first connecting portion 24a, the first connecting portion 34a, the first pressing portion 20a, and the first extending portion 22e (see FIG. 4). One-piece extension 22e is integrally formed of the same metal material , And the has a generally inverted H-shape as shown in FIG. 4 (A). The first contact 14 has a fixed portion 42a that fixed to the housing 12 (see FIG. 4). In the first contact 14, the first contact portion 22a, the first connection portion 34a, and the first connection portion 24a are arranged in a substantially crank-shaped positional relationship. The first contact portion 22a has a convex portion so as to be easily in contact with the connection object 40 of the FPC or FFC, and in the present embodiment, the first connection portion 24a is a surface mounting type (SMT as shown in FIG. 1). ), But may be dip type. The first extending portion 22e has a second contact portion 22c, that is, two contact portions 22a and 22c are provided to hold the connection object 40 of the FPC or FFC. By providing the contact portions 22a and 22c on both sides in the direction perpendicular to the insertion direction of the connection object 40 of the FPC or FFC, the connection object 40 of the FPC or FFC is held between the two contact portions 22a and 22c. As a result, the connection object 40 of the FPC or FFC can be reliably contacted.

  The first connecting portion 34a and the first pressing portion 20a operate in the following manner so that the first contact 14 comes into pressure contact with the connection object 40 when the connection object 40 is inserted. Is a portion of the first contact 14 indicating That is, after the connection object 40 is inserted into the insertion port 18 of the housing 12, the pressing portion 36 acts on the first pressing portion 20 a of the first contact 14 by the rotation of the slider 16, and the first pressing portion 20a is pushed up in a direction away from the substrate mounting surface by the pressing portion 36, whereby the first contact portion 22a presses and contacts the connection object 40. The sizes and shapes of the first connecting portion 34 a and the first pressing portion 20 a are appropriately designed in order to indicate such an operation mode.

Further, it is desirable that the first contact 14 have a projecting portion 26 at the tip end portion of the first pressing portion 20 a which is a portion on which the pressing portion 36 of the slider 16 acts. Thus, when the pressing force is applied to the first pressing portion 20 a of the first contact 14 by the pressing portion 36 by the rotation of the slider 16, the repulsive force against the rotation of the slider 16 is strong. It is desirable to prevent the central portion in the arrangement pitch direction from bulging in the direction of the arrow "c" in FIG. 1 (B). The size of the projecting portion 26 may be any size as long as it can play such a role, and is appropriately designed to the extent that the pressing portion 36 of the slider 16 is caught . Definitive to first slider position described below, when viewed in cross section perpendicular to the arrangement pitch direction, the leading end portion of the first pressure receiving portion 20a of the first contact 14, out of the two outer surfaces of the parallel housing 12 to the substrate mounting surface It is preferable to be configured to be located closer to the substrate mounting surface than a virtual plane including the outer surface of the housing 12 located farther from the substrate mounting surface .

  Another first contact will be described based on FIG. 4 (B). Here, only differences from the above-described first contact 14 will be described. The other first contacts 141 have the first extension 22e removed, and have a substantially reverse h-shape.

Next, the slider 16 which is another point of the present invention will be described. The slider 16 is an electrically insulating plastic and is manufactured by injection molding according to a known technique. The material is appropriately selected in consideration of dimensional stability, processability, cost and the like, but is generally polybutylene terephthalate. Examples include (PBT), polyamide (66 PA, 46 PA), liquid crystal polymer (LCP), polycarbonate (PC), and synthetic materials thereof. The slider 16 mainly includes a pressing portion 36 for pressing the first pressing portion 20 a of the first contact 14 and a required number of through holes 30 extending in the thickness direction of the slider 16. The through hole 30 includes a pressing portion 36 extending in the arrangement pitch direction for pressing the first pressing portion 20 a of the first contact 14, an opposing wall 35 opposed to the pressing portion 36 and extending in the arrangement pitch direction, and The pressing portions 36 extending in the pitch direction and the connecting walls 37 connecting the opposing walls 35 at intervals in the arranging pitch direction are defined. The first pressing portion 20a is inserted into the through hole 30 at least in the second slider posture among the first slider posture and the second slider posture, and the first pressing member 20a of the first contact 14 in the first slider posture The tip portion is located between the connecting walls 37. Definitive to first slider position, as viewed in cross section perpendicular to the arrangement pitch direction, the leading end portion of the first pressure receiving portion 20a of the first contact 14, out of the two outer surfaces of the parallel housing 12 to the substrate mounting surface, the substrate mounting It is desirable to be located closer to the substrate mounting surface than a virtual plane including the outer surface of the housing 12 located far from the surface . Further, when the first pressing portion 20a of the first contact 14 is pressed on both sides of the slider 16 in the longitudinal direction (arrangement pitch direction of the contacts), the operation portion of the slider 16 is lifted in the height direction (the upper side in the drawing). A lock (not shown) may be provided to engage the housing 12 to prevent it. The shape, size, etc. 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, size, strength, etc. of the connector.

The slider 16 is configured to be rotatable between the first slider posture and the second slider posture, and the pressing portion 36 is a portion that presses the first pressing portion 20 a of the first contact 14 in the first slider posture. It is desirable to use an elongated shape as its shape, and in this embodiment, it has an elliptical shape. By forming the elliptical shape in this manner, as shown in FIG. 2A, the slider 16 is rotated in the direction of the arrow "i" to change the size (size) of the pressing portion 36, thereby changing the first contact 14 The first pressing portion 20 a is lifted (moved in a direction away from the substrate mounting surface), and the first contact portion 22 a of the first contact 14 presses and contacts the connection object 40. As the shape of the pressing portion 36, the first pressing portion 20e of the first contact 14 is pushed away from the substrate mounting surface due to the difference in size (dimensions) such as the major axis and the minor axis as the slider 16 rotates. For example, it may be anything. It is desirable that the dimension of the slider 16 along the height direction of the connector 10 in the first slider posture be smaller than that of the opposing wall 35 in the cross section orthogonal to the arrangement pitch direction .

  In addition, when the slider 16 is rotated, the repulsive force to the rotation of the slider 16 is strong, and the central portion of the slider 16 in the arrangement pitch direction is prevented from expanding in the direction of the arrow “c” in FIG. For this purpose, through holes 30 with which the protrusions 26 of the first contact 14 engage are provided separately. By providing the through holes 30 separately, it is possible to prevent the strength increase of the slider 16 and the deformation at the time of rotation.

  Finally, the housing 12 will be described. The housing 12 is an electrically insulating plastic and is manufactured by injection molding according to a known technique. The material is appropriately selected in consideration of dimensional stability, processability, cost and the like, but is generally polybutylene terephthalate. Examples include (PBT), polyamide (66 PA, 46 PA), liquid crystal polymer (LCP), polycarbonate (PC), and synthetic materials thereof. The housing 12 is provided with an insertion groove 38 in which a required number of first contacts 14 and 141 are mounted, and is fixed by press fitting, hooking (lancing), welding or the like.

The main components are the same as those described above, and include a housing 121, first and second contacts 14 and 142, and a slider 161. The feature of this embodiment is that the two types of first and second contacts 14 and 142 are arranged in a staggered arrangement by changing the insertion direction into the housing 121, and are arranged by arranging a staggered arrangement by changing the insertion direction. It corresponds to narrowing the pitch and lowering the pitch. The housing 121 and the slider 161 are the same as those described above, and the first contact 14 is the same as that shown in FIG. FIG. 5 is a perspective view of the connector of the other embodiment, and FIG. 6 (A) is a portion of a second contact 142 at a portion of a second contact 142 in a state where the slider 161 is opened (second slider posture). FIG. 6B is a perspective view of the connector of the present invention cut in the extending direction, and FIG. 6B is a portion of the second contact 142 in a state (first slider posture) in which the connection object 40 is inserted and the slider is closed. FIG. 14 is a perspective view of the connector of the present invention cut in the direction in which the second contact 142 extends.

  The second contact 142 is also made of metal and is manufactured by press processing of a known technology. The material is the same as that of the first contact 14.

  Similarly to the first contact 14, the second contact 142 is of two types of substantially reverse h shape and substantially H shape, and the substantially reverse h shape is mainly located on the insertion port 18 side of the housing 121. A third contact portion 22b capable of contacting the surface 40a of the connection object 40 opposite to the substrate mounting surface, a second connection portion 24b connected to the substrate, and a fixation fixed to the housing 121. Extending from a portion (not shown), a second connection portion 34b provided between the third contact portion 22b and the second connection portion 24b, and a portion of the third contact portion 22b on the second connection portion 34b side. The second pressing portion 20b is provided. The third contact portion 22b, the second connection portion 34b, and the second connection portion 24b are disposed in a substantially U-shaped positional relationship. The substantially H-shaped member is provided with a second extending portion 44 extended from the portion on the second connecting portion 34 b side of the second connecting portion 24 b to the side where the slider 161 is positioned. The third contact portion 22 b has a convex shape so as to easily contact the connection object 40. In the present embodiment, the second connection portion 24b is of surface mount type (SMT) as shown in FIG. 5, but may be of dip type. In the embodiment of FIG. 6, the second connection portion 24b of the second contact 142 and the second connection portion 34b are in a positional relationship facing the third contact portion 22b, and the connection target object 40 on the substrate mounting surface side The case where the 4th contact part 22d which can contact the surface located in is provided is shown.

  The second connecting portion 34 and the second pressing portion 20b rotate the slider 161 to insert the pressing portion after the connection object 40 is inserted, as in the operation mode of the first contact 14 by the rotation of the slider 16. When 36 rotates, the second pressing portion 20b is pushed up in a direction away from the substrate mounting surface by the pressing portion 36, whereby the third contact portion 22b is in pressure contact with the connection object 40. The sizes and shapes of the second connecting portion 34 b and the second pressing portion 20 b are appropriately designed in order to indicate such an operation mode.

  Further, the protrusion 26 is provided at the tip of the second pressing portion 20 of the second contact 142, and when the pressing portion 36 of the slider 161 is rotated, the repulsion force against the rotation of the slider 161 is strong. It is desirable to prevent the central portion in the pitch direction from expanding in the direction of the arrow “c” in FIG. 6B, but considering the strength of the slider 161 due to the narrowing of the pitch, two types of contacts 14 , 142 are sufficient if provided at one of the contacts 14. The size of the projecting portion 26 may be any size as long as it can play such a role, and is appropriately designed to the extent that the pressing portion 36 of the slider 161 is caught.
