Description

  The present invention relates to a connector used in a mobile phone, a notebook computer, a digital camera, and the like, and more 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”). Is.

  A connector used for a cellular phone, a CCD camera, etc. is a narrow pitch and extremely thin (so-called light thin short), and is mainly composed of a housing, a contact, and a slider, and the housing and the slider sandwich the FPC or FFC. It is. There are various methods for holding the FPC or FFC between the housing and the slider. However, there are many methods 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 contacts are inserted and a fitting port into which an 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 that contacts the FPC 40 or FFC, a connection portion 24 connected to a substrate or the like, and a fixed portion 42 fixed to the housing 62. Has been. 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. The slider 66 includes a mounting portion 74 that is mainly 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 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, the FPC 40 or FPC is inserted as shown in FIG. The pressing portion 68 of the slider 66 is inserted in parallel with the FFC, and the FPC 40 or FFC is pressed against the contact portion 22 of the contact 64.

  In recent years, this type of connector 60 has been increasingly required to have a lower profile, but the connector 60 having the above-described structure has 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 contact 64 and the receiving portion 70, the thickness of the pressing portion 68 of the slider 66, and the thickness of the FPC 40 or FFC). Considering the low profile, the receiving part 70 of the contact 64 is omitted, and five layers (the walls on both sides in the thickness direction of the housing 62, the thickness of the contact part 22 of the contact 64, the thickness of the pressing part 68 of the slider 66, The thickness of the FPC 40 or the FFC) can be made, but there is a problem to be solved such that the height cannot be lowered any more due to the strength and specifications of each part.

  Further, in the connector 60 having the above-described 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 the connector is small. There is also the problem that workability becomes worse the more it becomes.

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

  The present invention has been made in view of such conventional problems, and the FPC 40 or the FFC can be reliably connected to the first and second contacts 14 and 142 by the slider 16 without impairing the strength and specifications of each part. It is intended to provide a connector that can be pressed against the first and second contact portions 22a and 22b, has good workability, and can reduce the pitch and reduce the height.

When the first pressing portion 36a of the slider 161 is rotated between the first pressing portion 20a of the first contact 14 and the first connecting portion 24a, the repulsive force against the rotation of the slider 161 is strong. Although the central portion of the slider 161 tends to swell in the direction of the arrow “c” in FIG. 6B, such a tendency can be prevented by providing the first projecting portion 26a. The size of the first protrusion 26a may be any size as long as it can fulfill such a role, and is appropriately designed to the extent that the first pressing portion 36a of the slider 161 is caught.

  Another first contact will be described with reference to FIG. Here, only differences from the first contact 14 described above will be described. The contact part 22 with the FPC 40 or the FFC provided in the direction extending from the fulcrum part 32 of another first contact 141 is deleted, and the shape is substantially inverted h-shaped.

  Further, the second contact of the present invention will be described. The second contact 142 is also made of metal, and is manufactured by a known press working. The material is the same as that of the first contact 14.

  Similarly to the first contact 14, the second contact 142 has two types of a substantially inverted h shape and a substantially H shape. The substantially inverted h shape has a second shape mainly contacting the FPC 40 or FFC. A contact portion 22b, a second connection portion 24b connected to the substrate, a second fixing portion 42b fixed to the housing 121, and a second provided between the second contact portion 22b and the second connection portion 24b. An elastic portion 34b, a second fulcrum portion 32b, and a second pressing portion 20b extending from the second elastic portion 34b are provided. The second contact portion 22b, the second elastic portion 34b, the second fulcrum portion 32b, and the second connection portion 24b are arranged in a substantially U shape. The substantially H-shaped one is provided with an extending portion 44 extending from the second fulcrum portion 32b in the same direction as the second pressing portion 20b. The second contact portion 22b has a convex shape so that it can easily come into contact with the FPC 40 or FFC. In the present embodiment, the second connection portion 24b is a surface mount type (SMT) as shown in FIG. Dip type is also acceptable.

  The second fulcrum portion 32b, the second elastic portion 34b, and the second pressing portion 20b are similar to the first contact 14 when the FPC 40 or the FFC is inserted. When the second pressing portion 36b rotates between the second pressing portion 20b of the second contact 142 and the housing 121 or between the second pressing portion 20b and the extending portion 44, the second pressing portion 20b is pushed up by the pressing portion 36 so that the second fulcrum portion 32b of the second contact 142 serves as a fulcrum, and the second elastic portion 34b of the second contact 142 tilts toward the second contact portion 22b, thereby The second contact portion 22b is pressed toward the FPC 40 or the FFC side. The size and shape of the second fulcrum portion 32b, the second elastic portion 34b, and the second pressing portion 20b are appropriately designed to achieve such an action.

  In addition, a second protrusion 26b is provided at the tip of the second pressing portion 20b of the second contact 142b. When the pressing portion 36 of the slider 161 is rotated between the second pressing portion 20b and the second connecting portion 24b of the second contact 142, the slider 161 has a strong repulsive force against the rotation. Although the central portion of 161 tends to swell in the direction of the arrow “c” in FIG. 6B, such a tendency can be prevented by providing the second projecting portion 26b. The size of the second protrusion 26b may be any size as long as it can fulfill such a role, and is appropriately designed to the extent that the pressing portion 36 of the slider 161 is caught.

The shaft 28 is a fulcrum for rotating the slider 161, and the slider 161 is appropriately mounted on both sides of the housing 12 in the longitudinal direction. Further, on both sides in the longitudinal direction, the slider 161 does not lift in the height (upper drawing) direction when the first and second pressing portions 20a, 20b of the first and second contacts 14, 142 are pressed. In order to achieve this, a lock portion that engages with the housing 12 is provided. The lock portion may have any shape, size, etc. as long as it can engage with the housing 12 and is appropriately designed in consideration of the above-described role, the size, strength, etc. of the connector.

  The pressing portion 36 is a portion that is pressed against the first and second pressing portions 20a and 20b of the first and second contacts 14 and 142, and has an elongated shape. In this embodiment, the pressing portion 36 has an elliptical shape. By making the shape oval in this way, the slider 161 is rotated in the direction of the arrow “A” as shown in FIG. 2A, and the first pressing portion 20a and the first connection portion 24a of the first contact 14 are formed. And between the second pressing portion 20b and the second connecting portion 24b of the second contact 142, the first and second contacts 14, The first and second pressing portions 20a, 20b of 142 are lifted to press the FPC 40 or the FFC against the first and second contact portions 22a, 22b of the first and second contacts 14, 142. As the shape of the pressing portion 36, the first pressing portion 20a and the first connecting portion 24a of the first contact 14, and the second pressing portion 20b and the second connecting portion 24b of the second contact 142, As long as the first and second pressing portions 20a and 20b of the first and second contacts 14 and 142 are pushed up by the difference in size such as the long axis and the short axis, any one may be used.

  Further, when the slider 161 is rotated, the repulsive force against the rotation of the slider 161 is strong, and the central portion of the slider 161 is prevented from swelling in the direction of the arrow “C” in FIG. 6B. Therefore, the locking hole 30 with which the second protrusion 26b of the second contact 142 is engaged is provided separately and independently. By providing the locking holes 30 independently, the strength of the slider 161 is prevented from being increased or deformed during rotation.

Finally, the housing will be described. This housing is an electrically insulating plastic, and is manufactured by injection molding of a known technique. The material is appropriately selected in consideration of dimensional stability, workability, cost, etc. In general, polybutylene terephthalate ( PBT), polyamide (66PA, 46PA), 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 the first and second contacts 14, 141, 142 are mounted, and is fixed by press-fitting, hooking (lance), welding, or the like.
