Hereinafter, structures of the connector 10 of the embodiment will be described.

First, mainly, with reference to FIGS. 5A to 5C to FIGS. 8A to 8C, the first contacts 100 and the second contacts 140 provided to the connector 10 of the embodiment will be described. Incidentally, the first contacts 100 each have a common structure, so that one first contact 100 will be described as a representative, and for the second contacts 140, similarly, one second contact 140 will be described as a representative.

The first contact 100, as illustrated in FIGS. 7A and 7B, and FIGS. 8A to 8C, is formed by, for example, performing punching to a metal plate having a predetermined thickness, and includes a first body portion 102. In the front end side of the first body portion 102, that is, the side to be inserted first into the housing body 14 described later, a fixing piece 106 is formed, and in the rear end side of the first body portion 102 that is the opposite side to the fixing piece 106, a first mounting portion 104 is formed to be mounted to the circuit board.

The fixing piece 106 is inserted into a fixing piece insertion hole 34 inside a fixing portion 32 formed in a rear surface 24 side of a first contact accommodation portion 56 of the housing body 14 described later, and is a portion to be fixed. Incidentally, in the fixing piece 106, at least one protrusion portion is formed, and in the first contact 100 of the embodiment, two fixing protrusion portions 108 to be press-fitted into the fixing piece insertion hole 34 of the housing body 14 are each formed.

In the supporting portion 150, a supporting protrusion 152 is formed protruding from a second surface side 174 that is another side, and is inserted into a recess portion 64 formed in the second contact accommodation portion 60 of the housing body 14 described later, and is hooked on a supporting groove portion 66 formed in the bottom surface 42 side of the recess portion 64, whereby the second contact 140 is supported in the second contact accommodation portion 60 (see FIG. 6).

In the second body portion 142, a second columnar portion 154 is formed extended upward, that is, toward the opposite direction to the side to which the second mounting portion 144 protrudes. Incidentally, in the embodiment, the second columnar portion 154 is perpendicular to the second body portion 142, and is extended from between the second mounting portion 144 and a substantially central portion of the second body portion 142, for example.

In the end portion of the opposite side to the second body portion 142 of the second columnar portion 154, a second arm portion 156 is extended toward the supporting portion 150 side along the second body portion 142. In addition, in the front end side of the second arm portion 156, an upper second contact portion 158 to be brought into contact with a conductor portion of the FPC 200 inserted is formed to protrude in a convex way to the second body portion 142 side.

Between the second body portion 142 and the second arm portion 156, a second intermediate arm portion 160 is formed extended along the second arm portion 156. In addition, the second intermediate arm portion 160 is formed to be slightly inclined toward the second arm portion 156. Further, in the end portion of the second intermediate arm portion 160, a lower second contact portion 162 is formed protruding in a convex way to the second arm portion 156 side. Incidentally, in the embodiment, the upper second contact portion 158 formed in the second arm portion 156 and the lower second contact portion 162 formed in the second intermediate arm portion 160 may be collectively referred to as the second contact portions 158 and 162. In addition, the second intermediate arm portion 160 is formed from a position close to the supporting portion 150, to be separated from the second columnar portion 154.

Incidentally, in the embodiment, the second press fitting portion 176 is formed in the second surface side 172 that is one side between the second columnar portion 154 and the second intermediate arm portion 160. In the second contact 140 of the embodiment, the second press fitting portion 176 is formed in the opposite side to the supporting protrusion 152; however, the second press fitting portion 176 may be formed in the second surface side 174 that is another side, or may be formed in the both surface sides 172 and 174.

In addition, similarly, not limited to the second surface side 174 that is the other side, the supporting protrusion 152 may be formed in the second surface side 172 that is one side or may be formed in the both surface sides 172 and 174.

Meanwhile, in the opposite side to the second arm portion 156 of the end portion of the second columnar portion 154, a second operating piece 166 is formed extended along the second body portion 142 of the second mounting portion 144 side. Incidentally, in the front end side of the second operating piece 166, a protruding portion 168 is formed more moderate than the first operating piece 122.

Between the second columnar portion 154 and the second mounting portion 144 of the second body portion 142, a second regulating protrusion portion 146 protruding toward the second operating piece 166 side is formed to protrude to the second columnar portion 154 side. In addition, a second protrusion portion 148 smaller than the second regulating protrusion portion 146 is formed in the second mounting portion 144 side. A space between the second operating piece 166, and the second protrusion portion 148 and the second regulating protrusion portion 146 of the second body portion 142 is a second pressing portion arrangement portion 170 in which a second pressing portion 90 formed in the operating portion 70 of the housing 12 described later is arranged (see FIG. 5C).

In the second contact 140, when the second operating piece 166 is pressed by the second pressing portion 90 formed in the operating portion 70 of the housing 12 in the direction opposite to the second body portion 142, the second arm portion 156 is moved to the second intermediate arm portion 160 side with the second columnar portion 154 as a pivot, and the FPC 200 is sandwiched between the upper second contact portion 158 of the second arm portion 156 and the lower second contact portion 162 of the second intermediate arm portion 160 (see FIG. 18C, FIG. 19C). Incidentally, details will be described later.

In a case where the connector 10 assembled is mounted to the circuit board, the first mounting portion 104 of the first contact 100 and the second mounting portion 144 of the second contact 140 are mounted at predetermined positions on the circuit board by soldering or the like, and fixed.

Next, connection of the FPC 200 to the connector 10 will be described mainly with reference to FIGS. 18A to 18C to FIGS. 20A and 20B. In the connection, first, the FPC 200 is inserted from the opening portion 18 formed in the front surface 16 of the housing body 14 in the housing 12 of the connector 10, and is arranged in a predetermined position of the arrangement portion 54 inside the housing body 14, as illustrated in FIGS. 18A to 18C. At this time, the FPC 200 is arranged such that conductor portions (not illustrated) formed in the FPC 200 correspond to the first contact portions 114 and 118 of the first contact 100, and the second contact portions 158 and 162 of the second contact 140. Incidentally, in a state where the FPC 200 is inserted into the housing 12 and arranged in the predetermined position, the FPC 200 is not sandwiched by the first contact 100 and the second contact 140, and is in a state of easily coming off.

After that, as illustrated in FIGS. 19A to 19C, the operating portion 70 of the housing 12 is operated, and the FPC 200 is sandwiched by the first contact 100 and the second contact 140. This operation is performed by moving the operating portion 70 with reference to the pressing portions 88 and 90 of the operating portion 70 such that the operating portion 70 shifts from a state of being stood to a state of being substantially parallel with respect to the housing body 14.

When the operating portion 70 is operated, the connection portion 94 by which the operating portion 70 and the housing body 14 are connected together is cut off, and the housing body 14 and the operating portion 70 are in a state of being separated (see FIGS. 20A and 20B). Further, the operating portion 70 is operated, whereby the longitudinal portion 92 parallel to the top surface portion 76 and the bottom surface portion 78 of the first pressing portion 88 and the second pressing portion 90 of the operating portion 70, is moved to stand up, and the first operating piece 122 of the first contact 100 and the second operating piece 166 of the second contact 140 are pressed upward. For that reason, the first operating piece 122 and the second operating piece 166 are pressed, whereby the first arm portion 112 and the second arm portion 156 are respectively moved to the first intermediate arm portion 116 side and the second intermediate arm portion 160 side with the first columnar portion 110 and the second columnar portion 154 as pivots, and conductor portions of the FPC 200 are respectively sandwiched between the upper first contact portion 114 and the lower first contact portion 118, and between the upper second contact portion 158 and the lower second contact portion 162.

At this time, the first contact portions 114 and 118 of the first contact 100, and the second contact portions 158 and 162 of the second contact 140 are brought into contact with the conductor portions of the FPC 200, and sandwich the FPC 200, whereby the FPC 200 is prevented from coming off. By the above, connection of the FPC 200 to the connector 10 is completed.

In a case where the FPC 200 is removed, the operating portion 70 is moved in the opposite direction, that is, moved to be perpendicular to the housing body 14. With this movement, the longitudinal portion 92 of each of the first pressing portion 88 and the second pressing portion 90 of the operating portion 70 is in a lying state, and pressing is released to the first operating piece 122 of the first contact 100 and the second operating piece 166 of the second contact 140 of the respective first pressing portion 88 and second pressing portion 90.

The first operating piece 122 and the second operating piece 166 are respectively moved to the first body portion 102 side and the second body portion 142 side with the first columnar portion 110 and the second columnar portion 154 as pivots, whereby the first arm portion 112 and the second arm portion 156 are moved in directions to be opened, and the first contact portions 114 and 118 of the first contact 100 and the second contact portions 158 and 162 of the second contact 140 are separated from the FPC 200, and contact to the conductor portion of the FPC 200 is released. After that, by pulling out the FPC 200, the FPC 200 can be removed from the connector 10.

Incidentally, in the embodiment, a case has been described where the plurality of first contacts 100 and second contacts 140 are used as the plurality of contacts; however, not limited thereto, only the plurality of first contacts 100 may be provided, or only the plurality of second contacts 140 may be provided.

In the embodiment, cutting off between the housing body 14 of the housing 12 and the connection portion 94 of the operating portion 70 has been performed by operating the operating portion 70 during connection to the FPC 200; however, not limited thereto, the cutting off may be performed during assembly of the connector 10. For example, when the first contact 100 and the second contact 140 are inserted into the housing body 14, by the first regulating protrusion portion 124 of the first contact 100 and the second regulating protrusion portion 146 of the second contact 140, the first pressing portion 88 and the second pressing portion 90 of the operating portion 70 are pressed in the insertion direction, whereby the connection portion 94 can be cut off.

Incidentally, the operating portion 70 cut off and separated, hooks on the first protrusion portion 126 of the first operating piece 122 of the first contact 100, thereby being prevented from coming off. In addition, the operating portion 70 of the housing 12 cut off and separated, can be repeatedly operated in a state of being separated, and connection and disconnection can be performed between the FPC 200 and the connector 10.

Further, in the embodiment, the connection portion 94 connecting the operating portion 70 and the housing body 14 of the housing 12 together is provided for all portions corresponding to the first pressing portion 88 and the second pressing portion 90 of the operating portion 70; however, not limited thereto, the connection portion 94 may be provided in a part of the portions if the housing body 14 and the operating portion 70 are in a state of being connected together in a case where the housing 12 is formed.
