Description

  The present invention relates to a connector, and more particularly, to a connector for connecting a flat or sheet-like connection object such as FPC (Flexible Printed Circuit) and FFC (Flexible Flat Cable).

In this type of connector, in order to prevent the connection object from coming out of the connector due to some stress acting between the two after the connection object is fitted to the connector, one having a retaining member is devised. Has been.
For example, Patent Document 1 discloses a connector in which a retaining member 2 is held in a housing 1 as shown in FIG. The retaining member 2 has an upper arm 4 and a lower arm 5 that extend in the insertion direction of the connection object 3, and has a structure in which respective central portions of the upper arm 4 and the lower arm 5 are coupled to each other by a coupling portion 6. .

A cam member 12A provided in the actuator 12 is disposed between the rear end portion of the upper arm 14A and the rear end portion of the lower arm 14B.

  The second contact 15 is fixed to the lower plate-like portion 22 on the front surface 11A side of the housing 11, and one end projects from the upper surface 22A of the lower plate-like portion 22 to the connection object receiving portion 23 to form the contact portion 15A. The other end is exposed from the front surface 11A of the housing 11 to form a substrate connection portion 15B.

As shown in FIG. 3, the lock member 16 has an upper arm 16 </ b> A and a lower arm 16 </ b> B extending in the Y direction from the front surface 11 </ b> A side to the rear surface 11 </ b> B side of the housing 11, respectively, similarly to the first contact 14. The central portions of the upper arm 16A and the lower arm 16B are connected to each other in the Z direction via a connecting portion 16C.
A front end portion 16D of the upper arm 16A extends toward the front surface 11A along the upper plate-shaped portion 21 of the housing 11, and a front end portion 16E of the lower arm 16B extends toward the front surface 11A along the lower plate-shaped portion 22 of the housing 11. The connection object receiving portion 23 is positioned between the front end portion 16D of the upper arm 16A and the front end portion 16E of the lower arm 16B. In addition, a locking protrusion 16F is formed on the front end portion 16E of the lower arm 16B so as to protrude into the connection object receiving portion 23 toward the upper plate-shaped portion 21.

The upper plate-like portion 21 is formed with an upper arm accommodating portion 21B opened upward, that is, in the + Z direction, and the front end portion 16D of the upper arm 16A is accommodated in the upper arm accommodating portion 21B. The −Y direction end portion and the −Z direction end portion of the upper arm housing portion 21B are closed, respectively, so that the front end portion 16D of the upper arm 16A is above the lower surface 21A of the upper plate-shaped portion 21 and the housing 11 Is restrained by the upper plate-like portion 21 so that displacement in the −Y direction toward the front surface 11A side and displacement in the −Z direction toward the lower plate-like portion 22 are prohibited.

Is housed in. The lower arm accommodating portion 22B of the lower plate-like portion 22 is such that the locking projection 16F is positioned below the upper surface 22A of the lower plate-like portion 22 when the front end portion 16E of the lower arm 16B is displaced in the -Z direction. It is pre-formed to a large size.

  Further, the cam member 12A of the actuator 12 is disposed between the rear end portion 16G of the upper arm 16A and the rear end portion 16H of the lower arm 16B, and further, a lower plate-shaped portion is disposed on the rear end portion 16H of the lower arm 16B. A housing holding portion 16J for holding at 22 is connected, and a substrate mounting portion 16K exposed from the back surface 11B of the housing 11 and mounted on a substrate (not shown) is connected.

FIG. 4 shows a connection end 17A of the connection object 17. The connection object 17 is made of, for example, FPC, and has a flexible insulating substrate 17B and a plurality of first contact portions 17C and a plurality of second contacts arranged on both surfaces of the insulating substrate 17B at the connection end portion 17A. A contact portion 17D is provided. Moreover, the notch part 17E is formed in the both ends of the connection end part 17A of the connection target object 17, respectively.
The arrangement pitch of the plurality of first contact parts 17C and the plurality of second contact parts 17D is equal to the arrangement pitch of the plurality of first contacts 14 and the plurality of second contacts 15 of the connector 100, and the connection object 17 is connected. When the end portion 17A is inserted into the connection object receiving portion 23 of the connector 100, the plurality of first contact portions 17C and the plurality of second contact portions 17D respectively correspond to the first contact 14 and the second contact corresponding to the connector 100. 15 is the same position in the X direction, and both notches 17E are arranged so as to be in the same position in the X direction as the corresponding lock members 16 respectively.

Next, the operation of the first embodiment will be described.
The connector 100 solders and connects the substrate connection portions 14D of the plurality of first contacts 14 and the substrate connection portions 15B of the plurality of second contacts 15 to corresponding connection pads of a substrate (not shown), and a pair of lock members 16. Each of the board mounting portions 16K is used in a state of being soldered and fixed to a corresponding mounting pad of a board (not shown).
First, as shown in FIGS. 1A to 1D, the connection end 17 </ b> A of the connection target 17 is inserted into the connection target receiving part 23 with the actuator 12 positioned at the unlock position.

  When the actuator 12 is positioned at the unlock position, the contact portion 14C of the first contact 14 is positioned above the lower surface 21A of the upper plate-shaped portion 21 of the housing 11 as shown in FIG. The connection end 17 </ b> A of the object 17 passes through between the contact portion 15 </ b> A of the second contact 15 protruding from the upper surface 22 </ b> A of the lower plate-like portion 22 and the lower surface 21 </ b> A of the upper plate-like portion 21. Inserted into. As a result, the plurality of first contact portions 17C of the connection object 17 are positioned immediately below the contact portions 14C of the corresponding first contacts 14, respectively, and the plurality of second contact portions 17D of the connection object 17 are respectively corresponding. The second contact 15 is positioned immediately above the contact portion 15A.

Further, at this time, the insulating substrate 17B located at both end portions of the connection end portion 17A of the connection object 17 is used for locking the lock member 16 protruding into the connection object receiving portion 23 as shown in FIG. The front end portion 16E of the lower arm 16B comes into contact with the protrusion 16F and is elastically pushed down into the lower arm housing portion 22B and inserted into the connection object receiving portion 23.
Then, the connection end 17A of the connection object 17 is connected to the connection object receiving part 23 until the tip of the connection end 17A of the connection object 17 comes into contact with the abutting surface 23A located at the back of the connection object receiving part 23. Is inserted into the notch portion 17E of the connection object 17, and the front end portion 16E of the lower arm 16B that has been pushed down into the lower arm accommodating portion 22B is eliminated. As a result, the locking protrusion 16F protrudes into the notch 17E of the connection object 17.

Thereafter, the actuator 12 is rotated around the rotation axis extending in the X direction, and the actuator 12 is positioned at the lock position as shown in FIGS.
At this time, as shown in FIG. 6, when the cam member 12A of the actuator 12 rotates, the distance between the rear end of the upper arm 14A of the first contact 14 and the rear end of the lower arm 14B is increased. Since the rear end portion of the arm 14B is fixed to the lower plate-like portion 22, the rear end portion of the upper arm 14A is elastically lifted in the + Z direction. Here, since the central portions of the upper arm 14A and the lower arm 14B are connected to each other in the Z direction, when the rear end portion of the upper arm 14A is lifted, the front end portion of the upper arm 14A is pushed down in the −Z direction. The contact portion 14 </ b> C protruding from the front end portion of 14 </ b> A is pressed against the connection object 17. Thereby, the plurality of first contact parts 17C arranged on the surface of the connection object 17 respectively contact the contact parts 14C of the corresponding first contacts 14 and are arranged on the back surface of the connection object 17. The plurality of second contact portions 17D are in contact with the contact portions 15A of the corresponding second contacts 15, respectively, and the plurality of first contact portions 17C and the plurality of second contact portions 17D of the connection object 17 and the connector 100 are connected. An electrical connection between the first contacts 14 and the second contacts 15 is established.

  Further, as shown in FIG. 7, the rotation of the cam member 12A of the actuator 12 increases the distance between the rear end portion 16G of the upper arm 16A of the lock member 16 and the rear end portion 16H of the lower arm 16B. Since the rear end portion 16H of the arm 16B is fixed to the lower plate-like portion 22, the rear end portion 16G of the upper arm 16A is elastically lifted in the + Z direction. Here, the front end portion 16D of the upper arm 16A is accommodated in the upper arm accommodating portion 21B of the upper plate-shaped portion 21 so as to move toward the front surface 11A side of the housing 11 in the −Y direction and to the lower plate-shaped portion 22. Since the displacement in the −Z direction is prohibited, the central portion of the lower arm 16B is pulled in the + Z direction via the connecting portion 16C, and the housing holding portion 16J of the rear end portion 16H of the lower arm 16B is moved to the lower plate. Since the substrate mounting portion 16K is held on the substrate (not shown) while being held by the shape portion 22, the front end portion 16E of the lower arm 16B is lifted in the + Z direction. As a result, the locking protrusion 16F that protrudes from the front end portion 16E of the lower arm 16B further protrudes into the cutout portion 17E of the connection object 17.

  In this way, the connection object 17 is fitted into the connector 100. At this time, the surface of the connection end 17A of the connection object 17 facing the + Z direction contacts the lower surface 21A of the upper plate-shaped part 21. The plurality of second contact portions 17D arranged on the back surface facing the −Z direction are pressed against the contact portions 15A of the corresponding second contacts 15, respectively, and further, the connection ends in the vicinity of the notches 17E. The back surface of the portion 17A is pressed in the + Z direction by the front end portion 16E of the lower arm 16B of the lock member 16.

For this reason, even if the stress in the Z direction acts on the connection object 17 connected to the connector 100, the connection end 17 </ b> A of the connection object 17 is − also in the + Z direction relative to the connector 100. There is no movement in the Z direction, and the position of the connection end 17A is securely locked in the connection object receiving portion 23. Further, the housing holding portion 16J of the lower arm 16B of the lock member 16 is held by the lower plate-like portion 22, and the board mounting portion 16K is fixed to a corresponding mounting pad of a board (not shown), and is attached to the front end portion 16E of the lower arm 16B. Since the protruding locking protrusion 16F protrudes into the notch 17E of the connection object 17, even if a force pulling out from the connector 100 acting in the -Y direction acts on the connection object 17, the locking protrusion 16F is used. The protrusion 16F is caught by the notch 17E, so that the connection object 17 is prevented from coming out of the connector 100.
Therefore, a highly reliable electrical conduction state is realized between the connection object 17 and the connector 100.

Embodiment 2
In the first embodiment, as shown in FIG. 3, when the actuator 12 is located at the unlocking position, the locking protrusion 16F of the locking member 16 has already protruded into the connection object receiving portion 23, The connection end 17A of the connection object 17 is inserted into the connection object receiving part 23 while contacting the locking projection 16F and elastically pushing down the front end 16E of the lower arm 16B into the lower arm housing part 22B. However, it is not limited to this.

For example, like the connector 101 of the second embodiment shown in FIG. 8, when the actuator 12 is positioned at the unlocking position, the locking projection 161 </ b> F of the locking member 161 is the lower arm accommodating portion 22 </ b> B. It may be accommodated inside and may be located below the upper surface 22 </ b> A of the lower plate-like portion 22.
Accordingly, when the connection end 17A of the connection object 17 is inserted into the connection object receiving part 23, the front end 161E of the lower arm 161B is not pushed down by contacting the locking protrusion 161F of the lock member 16. It becomes easy to insert the connection object 17 into the connection object receiving part 23.
The connector 101 according to the second embodiment uses the lock member 161 instead of the lock member 16 in the connector 100 of the first embodiment, and other members are the same as those of the connector 100 of the first embodiment. The locking member 161 is the same as the lower arm 16B of the locking member 16, the front end portion 16E of the lower arm 16B, and the locking projection 16F, but the lower arm 161B and the lower arm of the locking member 161 are the same. The configuration is the same as that of the lock member 16 of the first embodiment except that the front end portion 161E of 161B and the locking projection 161F are used.

  When the actuator 12 is positioned at the lock position, as shown in FIG. 9, the rear end portion 16G of the upper arm 16A of the lock member 161 is + Z by the cam member 12A of the actuator 12 as in the first embodiment described above. Is lifted in the direction, the front end portion 161E of the lower arm 161B is lifted in the + Z direction, and the locking protrusion 161F housed in the lower arm housing portion 22B of the lower plate-like portion 22 is the cutout portion of the connection object 17 It will be in the state which protrudes in 17E. Therefore, similarly to the connector 100 of the first embodiment, it is possible to effectively prevent the connection object 17 from coming off from the connector.

In the first and second embodiments, the lock member 16 or 161 has the housing holding part 16J and the board mounting part 16K connected to the rear end part 16H of the lower arm 16B or 161B, and the housing holding part 16J Is held by the lower plate-like portion 22 and the substrate mounting portion 16K is fixed to a corresponding mounting pad of a substrate (not shown) by soldering, but is not limited thereto.
The rear end portion 16H of the lower arm 16B or 161B of the lock member 16 or 161 only needs to be fixed in position relative to the housing 11. For example, the lock member 16 or 161 does not include the housing holding portion 16J and is mounted on the board. The configuration may be such that the portion 16K is simply fixed to a mounting pad of a substrate (not shown). In this case, the housing 11 is fixed to the substrate by soldering the substrate connection portions 14D of the plurality of first contacts 14 and the substrate connection portions 15B of the plurality of second contacts 15 to corresponding connection pads of the substrate (not shown). Therefore, by fixing the board mounting portion 16K of the lock member 16 or 161 to the mounting pad of the board, the position of the lock member 16 or 161 is fixed to the housing 11 via the board.
