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 structure as described above, 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 is reliably pressed against the contact portion 22 of the contact 14 by the slider 16 without impairing the strength and specifications of each part. Therefore, it is intended to provide a connector that can be manufactured, has good workability, and can reduce the pitch and reduce the height.

  The low profile for the above purpose is a connector 10 that is detachably fitted to the FPC 40 or FFC, and has a required number of contacts 14 having contact portions 22 that contact the FPC 40 or the FFC, and the contacts 14 hold The contact portion of the contact 14 in the connector 10 including the housing 12 having the fitting port 18 into which the FPC 40 or the FFC is inserted and the slider 16 that presses the FPC 40 or the FFC against the contact 14. An elastic part 34 and a fulcrum part 32 between the contact part 22 and the connection part 24, the contact part 22, the elastic part 34, the fulcrum part 32 and the connection part 24 are arranged in a substantially crank shape, and A pressing portion 20 extending from the elastic portion 34 is provided at a position facing the connecting portion 24, and the slider 1 By providing a pressing portion 36 continuously provided in the longitudinal direction, the pressing portion 36 is mounted on the housing 12 so as to be rotatable between the connection portion 22 of the contact 14 and the pressing portion 20. Can be achieved.

  The above-mentioned purpose of lowering the back and narrowing the pitch is a connector 101 that is detachably fitted to the FPC 40 or FFC, and has a required number of contacts 14 and 142 having contact portions 22 that contact the FPC 40 or the FFC. And a housing 121 having a fitting port 18 into which the contacts 14 and 142 are held and fixed and the FPC or the FFC is inserted, and a slider 161 that presses the FPC 40 or the FFC against the contacts 14 and 142. In the connector 101 provided, two types of contacts 14 and 142 are arranged in a staggered manner, and one contact 14 is provided with an elastic portion 34 and a fulcrum portion 32 between the contact portion 22 and the connection portion 24 and the contact portion. 22, the elastic portion 34, the fulcrum portion 32, and the connection portion 24 are arranged in a substantially crank shape. The pressing portion 20 extending from the elastic portion 34 is provided at a position facing the connection portion 24, and the elastic portion 34 and the fulcrum between the contact portion 22 and the connection portion 24 are provided on the other contact 142. The contact portion 22, the elastic portion 34, the fulcrum portion 32, and the connection portion 24 are arranged in a substantially U shape and extend from the elastic portion 34 in the opposite direction to the contact portion 22. A pressing portion 20 is provided, and a pressing portion 36 provided in the longitudinal direction is provided on the slider 161, and the pressing portion 36 is between the connection portion 24 of one contact 14 and the pressing portion 20 and the other. This can be achieved by mounting the slider 161 to the housing 121 so as to be rotatable between the holding portion 20 of the contact 142 and the housing 121.

  Protruding portion 26 is provided at the tip of pressing portion 20 of one or the other of contacts 14 and 142 so that pressing portion 36 of slider 161 does not move toward connecting portion 24 of one of contacts 14. desirable. By providing the protruding portion 26 in this manner, when the pressing portion 36 of the slider 161 is rotated between the pressing portion 20 of the contact 14 and the connecting portion 24, the repulsive force against the rotation of the slider 161 is strong. It is possible to prevent the center portion of the slider 161 from bulging in the direction of the arrow “C” in FIG.

  In addition, it is preferable that the shape of the pressing portion 36 of the sliders 16 and 161 is an elongated shape. For example, it may be oval. By adopting such an elongated shape, when the sliders 16 and 161 are rotated, the pressing portions 20 of the contacts 14, 141 and 142 are surely pushed upward, and the contact portions 22 can be easily moved to the FPC 40 or FFC. Can be contacted.

  The sliders 16 and 161 are preferably provided with locking holes 30 that engage with the protrusions 26 of the required number of the contacts 14, 141, and 142, and the locking holes 30 are made independent. Thus, by making the said locking hole 30 independent independently, the said sliders 16 and 161 can be rotated firmly and reliably.

  Further, a contact portion 22 that contacts the FPC 40 or FFC is also provided in a direction extending from the fulcrum portion 32 of the one contact 142. Thus, by providing the contact portions 22 on both sides in a direction perpendicular to the insertion direction of the FPC 40 or FFC, the FPC 40 or FFC is sandwiched between the contact portions 22 and 22, and the FPC 40 or FFC is securely connected to the FPC 40 or FFC. You can touch.

  Furthermore, 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. Thus, by providing the contact portions 22 on both sides in a direction perpendicular to the insertion direction of the FPC 40 or FFC, the FPC 40 or FFC is sandwiched between the contact portions 22 and 22, and the FPC 40 or FFC is securely connected to the FPC 40 or FFC. You can touch.

  An extension part 44 extending from the fulcrum part 32 of the other contact 142 in the direction opposite to the connection part 24 is provided, and the pressing part 36 of the slider 161 is located between the extension part 44 and the pressing part 20. The slider 161 is mounted on the housing 121 so as to be freely rotatable. By providing the extended portion 44 as described above and rotating the slider 161 between the extended portion 44 and the pressing portion 20, the contact portion of the other contact 142 is more reliably rotated. 22 can be pressed against the FPC 40 or FFC.

FIG. 3 is a perspective view of the slider. 4A is a perspective view of a contact having one contact portion, and FIG. 4B is a perspective view of another contact having two contact portions.

  The connector of the present invention mainly includes a housing, a slider, and a contact.

The components of the connector of the present invention will be described with reference to the drawings.
First, the contact that is the point of the present invention will be described. This contact is made of metal and is manufactured by a known press working. The material of the contact is required to be springy or conductive, and examples thereof include brass, beryllium copper, and phosphor bronze.

  The contact 14 has a substantially inverted H shape as shown in FIG. 4A, and mainly has a contact portion 22 that contacts the FPC 40 or FFC, a connection portion 24 connected to the substrate, and a fixing portion fixed to the housing 12. 42, the elastic portion 34 and the fulcrum portion 32 provided between the contact portion 22 and the connection portion 24, and the support portion 20 and the fulcrum extended from the elastic portion 34 at a position facing the connection portion 24. Another contact portion 22 that contacts the FPC 40 or FFC is also provided in a direction extending from the portion 32. The contact portion 22 on the upper side (the upper side in FIG. 2A), the elastic portion 34, the fulcrum portion 32, and the connection portion 24 are arranged in a substantially crank shape. The contact portion 22 has a convex shape so that it can easily come into contact with the FPC 40 or FFC. In the present embodiment, the connection portion 24 is a surface mount type (SMT) as shown in FIG. good. That is, the two contact portions 22 and 22 are provided so as to sandwich the FPC 40 or the FFC. By providing the contact portions 22 on both sides in a direction perpendicular to the FPC 40 or FFC insertion direction, the FPC 40 or FFC is sandwiched between the two contact portions 22 and 22 and reliably contacts the FPC 40 or FFC. become able to.

  The fulcrum part 32, the elastic part 34, and the pressing part 20 are parts 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, the pressing portion 36 of the slider 16 rotates between the connection portion 24 of the contact 14 and the pressing portion 20. When the portion 20 is pushed up by the pressing portion 36, the fulcrum portion 32 of the contact 14 is used as a fulcrum, and the elastic portion 34 of the contact 14 is inclined toward the contact portion 22, whereby the contact portion 22 is moved to the FPC 40 or FFC side. Pressed. The size and shape of the fulcrum part 32, the elastic part 34, and the pressing part 20 are appropriately designed in order to achieve such an action.

  Further, a protrusion 26 is provided at the tip of the pressing portion 20 of the contact 14, and the slider 16 is rotated when the pressing portion 36 of the slider 16 is rotated between the pressing portion 20 of the contact 14 and the connecting portion 24. Therefore, it is desirable to prevent the central portion of the slider 16 from bulging in the direction of the arrow “B” in FIG. The size of the protruding portion 26 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 16 is caught.

  Another contact will be described with reference to FIG. Here, only differences from the 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 the contact 141 is deleted, and the shape is 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 and is manufactured by a known technique of injection molding. 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 slider 16 mainly includes 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 locking hole 30 that engages the protruding portion 26 of the contact 14. And. The shaft 28 is a fulcrum for rotating the slider 16, and the slider 16 is appropriately mounted on both sides in the longitudinal direction of the housing 12 so as to be rotatable. Further, on both sides in the longitudinal direction, there are provided lock portions that engage with the housing 12 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. It has been. 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 pressing portion 20 of the contact 14, and the shape thereof is preferably an elongated shape. In this embodiment, the pressing portion 36 has an elliptical shape. By forming the ellipse in this way, the slider 16 is rotated in the direction of the arrow “A” as shown in FIG. 2A and is rotated between the holding 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. As the shape of the pressing portion 36, any shape can be used as long as the pressing portion 20 of the contact 14 can be rotated between the pressing portion 20 and the connecting portion 24 of the contact 14 and the pressing portion 20 of the contact 14 can be pushed up due to a difference in size such as a major axis and a minor 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 being swollen in the direction of the arrow “B” in FIG. For this purpose, a locking hole 30 with which the protruding portion 26 of the contact 14 engages is provided independently. By providing the locking holes 30 independently, the strength of the slider 16 is prevented from being increased and deformation at the time of rotation is prevented.

  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 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 to which the shaft 28 of the slider 16 is rotatably mounted are provided. The shape and size of the bearing portion may be any as long as the shaft 28 of the slider 16 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. On both sides in the longitudinal direction, locking portions are provided at positions corresponding to the lock portions of the slider 16.

  Another embodiment of the present invention will be described with reference to FIGS. The main components are the same as those described above, and include a housing, a contact, and a slider. The feature of this embodiment is that the two types of contacts 14 and 142 are arranged in a staggered manner by changing the direction of insertion into the housing 121. By changing the insertion direction and arranged in a staggered manner, the pitch can be narrowed. This corresponds to low 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 described above with reference to FIG. FIG. 5 is a perspective view of another connector, FIG. 6A is a perspective view of the connector of the present invention cut at the other contact portion with the slider opened, and FIG. 5B is a perspective view of the FPC inserted. It is a perspective view of the connector of this invention cut | disconnected by the other contact part of the state in which the slider was closed.

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

  The other contact 142 has two types of substantially reverse h-shape and substantially H-shape as in the case of the one contact 14, and the substantially reverse h-shape contact mainly contacts the FPC 40 or FFC. The portion 22 and the connecting portion 24 connected to the substrate, the fixing portion 42 fixed to the housing 121, the elastic portion 34 and the fulcrum portion 32 provided between the contact portion 22 and the connecting portion 24, and the elastic portion 34 are extended. The provided pressing part 20 is provided. 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 extending portion 44 extending from the fulcrum portion 32 in the direction opposite to the connecting portion 24. The contact portion 22 has a convex shape so that it can easily come into contact with the FPC 40 or FFC. In the present embodiment, the connection portion 24 is a surface mount type (SMT) as shown in FIG. good.

  The fulcrum part 32, the elastic part 34, and the pressing part 20 are similar to the one contact 14 when the pressing part 36 of the slider 161 is pressed by the contact 142 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, whereby the fulcrum portion 32 of the contact 142 is moved. The contact portion 22 is pressed toward the FPC 40 or the FFC side by using the elastic portion 34 of the contact 142 as the fulcrum and tilting toward the contact portion 22 side. The size and shape of the fulcrum part 32, the elastic part 34, and the pressing part 20 are appropriately designed in order to achieve such an action.

  In addition, since the protrusion 26 is provided at the tip of the pressing portion 20 of the contact 142 and the pressing portion 36 of the slider 161 is rotated, the repulsive force against the rotation of the slider 161 is strong. It is desirable to prevent swelling in the direction of the arrow “c” in FIG. 6B, but considering the strength of the slider due to the narrowing of the pitch, one of the two types of contacts 14 If it is provided, it is sufficient. The projecting portion 26 may have 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.

  As is apparent from the above description, the connector of the present invention provides the following excellent effects.

  (1) Since the sliders 16 and 161 are rotated on the contact connecting portion 24 side of the housings 12 and 121, the contact portions 22 of the contacts 14, 141 and 142 are brought into contact with the FPC 40 or FFC. , 121 without inserting the sliders 16, 161 into the fitting ports 18, and the connectors 10, 101 can be lowered in height by the thickness of the sliders 16, 161.

  (2) Two types of contacts 14 and 142 are prepared, one contact 14 is inserted from the connection portion 24 side, the other contact 142 is inserted from the fitting port 18 side, and the slider 161 is inserted at the connection portion 24 side. By turning, narrowing and low profile can be easily achieved.

  (3) After the FPC 40 or FFC is inserted into the fitting port 18 of the housing 121, the pressing portion 36 of the slider 161 rotates between the connection portion 24 of the one contact 14 and the pressing portion 20. Then, when the pressing portion 20 is pushed up by the pressing portion 36, the fulcrum portion 32 of the contacts 14, 142 is used as a fulcrum, and the elastic portion 34 of the contacts 14, 142 is inclined toward the contact portion 22 side. Since the contact portion 22 is pressed to the FPC 40 or FFC side, the contact portion 22 of the contacts 14 and 142 and the FPC 40 or FFC can be reliably connected.

  (4) After the FPC 40 or FFC is inserted into the fitting port 18 of the housing 121, the pressing portion 36 of the slider 161 is located between the pressing portion 20 of the other contact 142 and the housing 121 or the pressing force. When rotating between the receiving portion 20 and the extending portion 44, the pressing portion 20 is pushed up by the pressing portion 36, so that the fulcrum portion 32 of the contacts 14, 142 serves as a fulcrum, and the elasticity of the contacts 14, 142 is obtained. Since the contact portion 22 is pressed toward the FPC 40 or FFC when the portion 34 is tilted toward the contact portion 22, the contact portion 22 of the contacts 14 and 142 can be reliably connected to the FPC 40 or FFC. .

  (5) Since the protruding portion 26 is provided at the tip of the pressing portion 29 of one of the contacts 14 or both 14, 142, the pressing portion 36 of the slider 161 is connected to the pressing portion 20 of the contact 14 and the connection portion 24. Even if the repulsive force with respect to the rotation of the slider 161 is strong when the slider 161 is rotated, the center portion of the slider 161 can be prevented 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 an elongated shape (there is a major axis and a minor axis), the contacts 14 and 141 are surely secured when the sliders 16 and 161 are rotated. , 142 can be pushed upward and the contact portion 22 can be easily brought into contact with the FPC 40 or the FFC.

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

  (8) When the contact portion 22 that contacts the FPC 40 or FFC is provided also in the direction extending from the fulcrum portion 32 of one of the contacts 14, the contact portions are arranged on both sides in the direction perpendicular to the insertion direction of the FPC 40 or FFC. 22 is provided, and the FPC 40 or the FFC is sandwiched between the contact portions 22 and 22, so that the FPC 40 or the FFC can be reliably contacted.

  (9) When the contact portion 22 that contacts the FPC 40 or FFC is also provided between the fulcrum portion 32 of the other contact 142 and the connection portion 24, the contact portion 22 is provided on both sides in the direction perpendicular to the FPC 40 or FFC insertion direction. 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.

  (10) The side into which the FPC 40 or FFC is inserted is the fitting port 18 of the housings 12 and 121, and the operation of pressing the contact portion 22 of the contacts 14, 141, 142 against the FPC 40 or FFC is the connection portion 24 side of the contacts 14, 141, 142. Therefore, even if the connectors 10 and 101 are downsized, the workability is not affected and the work can be easily performed.

The present invention relates to a connector used in a mobile phone, a notebook computer, a digital camera, and the like, and particularly contacts a connection object of a flexible printed circuit board (hereinafter referred to as “FPC”) or a flexible flat cable (hereinafter referred to as “FFC”). It is related with the mechanism which presses.

  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 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 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 (FIG. 7) 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 structure as described above, 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, without impairing the strength or specifications of each part, the FP C also operates the slider reliably with respect to the connection object of the FFC contactor Therefore, it is possible to provide a connector that can be configured such that the contact portion of the head is pressed and contacted , has good workability, and can reduce the pitch and reduce the height.
