Description

Connector {CONNECTOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting to a board-like or sheet-like connection object such as a flexible printed circuit (FPC) or a flexible flat cable (FFC).

As a connector which prevents a board | substrate- or sheet-shaped connection object from falling out, For example, patent document 1 (Unexamined-Japanese-Patent No. 2004-71314) or patent document 2 (Japanese Unexamined-Japanese-Patent No. 2009-283309). Is disclosed in.

The connector of patent document 1 is equipped with the actuator provided with the processus | protrusion, and the housing which rotatably supports an actuator. In the housing, a receiving hole corresponding to the projection of the actuator is formed. When the FPC / FFC is inserted from the front end of the connector and the actuator is turned forward, the projection of the actuator is inserted into the receiving hole of the housing through the hole of the FPC / FFC. This prevents the FPC / FFC from falling out.

However, in the connector described in Patent Literature 1, the actuator is opened when the FPC / FFC is forcibly pulled out or when the FPC / FFC is shaken, which may cause the FPC / FFC to fall out. In order to prevent such an undesired dropout, the length of the projections should be increased, but there is a problem that the length of the projections interferes with the insertion of the FPC / FFC into the connector.

The connector of patent document 2 is provided with the housing which has the lock arm in which the coupling part was formed, and the actuator rotatably supported by the housing. In the actuator, a cam portion for bending the lock arm is formed. Opening the actuator causes the cam portion to bend the lock arm to displace the engagement portion upward. This allows the FPC / FFC to be inserted into the connector. In the state where the FPC / FFC is inserted into the connector, the engaging portion returns to a predetermined position when the actuator is laid down. At this time, the coupling portion is located in the coupling hole of the FPC / FFC. This prevents the FPC / FFC from falling out.

Since the connector described in this patent document 2 bends a lock arm by operation of an actuator, there exists a problem of intensity | strength.

An object of the present invention is to provide a connector that is resistant to unreasonable pulling or shaking of a connection object and that has no problem in strength.

One aspect of the present invention provides a connector. The connector is provided with an insertion port at the front end. The connector is connected to a connection object inserted from the insertion port toward the rear end. The connection object is a board or sheet. The said connection object is provided with the contact part and the to-be-engaged part. The connector includes a contact having a contact portion, a housing for supporting the contact, and an actuator supported in the housing so as to be rotatable between a closed position and an open position. It has an actuator. The actuator connects the contact portion of the contact to the contact portion of the connection object in accordance with a rotation operation of rotating the actuator from the open position toward the closed position. The actuator has a coupling portion and a contact portion. The contact portion is configured to be located behind the engaging portion when the actuator is in the closed position, and to contact the main surface of the connecting object at least when the engaging portion engages the engaged portion of the connecting object. .

According to the present invention, even if the connection object (for example, FPC / FFC) is forcibly removed or the connection object is shaken, the coupling portion formed on the actuator couples to the engagement portion of the connection object, and the contact portion of the actuator is connected to the connection object. Since it is comprised so that the main surface may contact, the actuator can be prevented from accidentally opening without lengthening a coupling part length.

A plurality of signal terminals 52 are formed. Moreover, the recessed part 53 recessed inward of the Y direction is formed in the both ends of the left-right direction (Y direction) of the FPC / FFC50. That is, the recessed part 53 is formed so that the some contact part 52 may be inserted from a Y direction. An edge on the side of the edge portion 51 of the recess 53 functions as a to-be-engaged portion 54 as described later.

Referring back to FIGS. 1 to 7, the connector 1 has a front end 2 and a rear end 3 and an insertion hole for inserting the FPC / FFC 50. (4) is provided in the front end (2). The connector 1 is connected to the FPC / FFC 50 inserted from the insertion port 4 toward the rear end 3. Hereinafter, the structure of the said connector 1 and the connection method with the FPC / FFC50 are demonstrated in detail.

The connector 1 according to the present embodiment includes a housing 10 made of an insulating material, a plurality of contacts 20 made of metal, and an actuator made of an insulating material. 30 and a metal hold down 40 which is connected to and fixed to a circuit board (not shown).

3, 4 and 6 to 8, an opening 11 is formed at the front end 10a of the housing 10. As shown in FIG. The opening 11 penetrates the housing 10 in the X direction and has a shape that is long and thin in the Y direction when the front end 10a of the housing 10 is viewed along the X direction. The opening part 11 which concerns on this embodiment defines the insertion opening 4 of the connector 1 mentioned above. The bottom face of the opening part 11 (namely, the insertion hole 4) functions as the receiving surface 12 which receives the FPC / FFC 50 inserted through the insertion hole 4. As best shown in Fig. 8, the evacuation hole 13 is formed in the vicinity of both ends of the receiving surface 12 in the Y direction in the -Z direction (downward). On the rear end 10b of the housing 10, a support portion 14, which is a hole for supporting the contact 20, is formed. These support parts 14 reach the receiving surface 12. Moreover, the bearing part 15 is formed so that the receiving surface 12 may be inserted in a Y direction. The bearing portion 15 is a groove extending in the Z direction (upward) as a groove recessed toward the outer side in the Y direction.

3, 4, 6, and 7, each contact 20 includes a lower part 22 formed with a contact part 21 and an upper part. Section 23, a connecting portion 24 connecting the lower portion 22 and the upper jaw portion 23, and a supported portion for elastically supporting the connecting portion 24. (25) and a fixed end portion (26) extending from the supported portion (25) to the rear lower side (the X direction and the -Z direction). The connection part 24 connects the lower part 22 and the upper part 23 so that the shape of a tuning folk shape may be comprised. The supported portion 25 is supported by the support portion 14. The fixed end 26 is connected and fixed to a corresponding signal terminal (not shown) on the circuit board (not shown).

In this embodiment, since the connection part 24 is elastically supported by the to-be-supported part 25, the part which the upper part 23 and the lower part 22 are supported by the to-be-supported part 25 of the connection part 24 is supported. The movement is similar to the rotation around. For this reason, if the upper part 23 is lifted upwards, the lower part 22 will also be lifted and the contact part 21 will move upwards.

The actuator 30 is supported by the housing 10 so as to be rotatable between an open position (see FIGS. 1 to 4) and a closed position (see FIGS. 5 to 7). . This actuator 30 is for connecting the contact portion 21 of the contact 20 to the contact portion 52 of the FPC / FFC 50 when rotated from the open position toward the closed position.

The actuator 30 according to the present embodiment is configured to rotate from the open position to the closed position by lying down toward the rear (X direction). That is, the direction of rotation from the open position of the actuator 30 which concerns on this embodiment to the closed position becomes opposite to the rotation direction of the actuator in the connector of patent document 1. As shown in FIG.

9 and 10, the actuator 30 according to the present embodiment is positioned near the rotation shaft 31 protruding outward from the left and right ends (both ends in the Y-direction) and the left and right ends thereof. A coupling portion 32 and a contact portion 33, a receiving portion 34 formed corresponding to the contact 20, and a lift up portion formed in the receiving portion 34. 35 and an enclosure 36 are provided.

Specifically, the rotation shaft 31 according to the present embodiment is located at the foremost end of the actuator 30 when the actuator 30 is in the closed position, so that the rotation shaft 31 is rotatable and movable in the vertical direction (Z direction). It is supported by the bearing part 15 of the housing 10.

The engaging portion 32 has a projection shape, and when the actuator 30 is in the open position, protrudes downward (-Z direction), and moves in accordance with the rotation of the actuator 30. The evacuation hole 13 formed in the housing 10 is for smoothly moving the coupling part 32, and the evacuation hole 13 itself does not have to be engaged with the coupling part 32. Therefore, the evacuation hole 13 may not be as deep as that of the connector of patent document 1.

3 and 4, when the actuator 30 is in the open position, the coupling part 32 according to the present embodiment is positioned so as not to interfere with the insertion of the FPC / FFC 50. As shown in FIG. Consists of. On the other hand, when the actuator 30 is in the closed position in the state where the FPC / FFC 50 is inserted, as shown in FIG. It is comprised so that it may be located ahead of the coupling part 54. That is, in the case where the actuator 30 is in the closed position in the state where the FPC / FFC 50 is inserted, the engaging portion 32 according to the present embodiment is located in the recess 53. For this reason, when the FPC / FFC 50 tries to move forward (that is, when the FPC / FFC 50 is to be removed), the engaging portion 54 is engaged with the engaging portion 32.

Especially the coupling part 32 which concerns on this embodiment is located in the vicinity of the rotating shaft 31. As shown in FIG. For this reason, the magnitude | size in the front-back direction (X direction) of the connector 1 can be made small. In addition, as can be understood from FIGS. 7 and 10, in the cross section along the XZ plane, two-thirds or more of the engaging portions 32 are formed when the actuator 30 is in the closed position. Is located behind the center 31c. In such a configuration, it is possible to lower the probability that the insertion of the FPC / FFC 50 into the insertion port 4 is disturbed when the actuator 30 is in the open position. In view of the above effects, as will be apparent, the engaging portion 32 is located most of the (more preferably all) rearward of the center 31c of the rotational shaft 31 when the actuator 30 is in the closed position. It is preferable.

7 and 10, the contact portion 33 has a surface parallel to the YX plane when the actuator 30 is in the closed position, and is located behind the engaging portion 32 (X direction). . In particular, in this embodiment, the contact part 33 is located behind the rotating shaft 31, when the actuator 30 is in a closed position. This contact portion 33 is intended to remove the FPC / FFC 50 by force, and at least when the engaging portion 32 engages the engaged portion 54 of the FPC / FFC 50, the FPC / FFC 50 It is comprised so that the upper surface 50a of () may contact. For this reason, when a force such as to press the coupling portion 32 in the -X direction (forward) from the coupled portion 54 to the coupling portion 32 is applied, the contact portion 33 is applied to the FPC / FFC 50. Since the pressure is applied to the upper surface 50a, the FPC / FFC 50 does not come out of the coupling portion 32 even if the protruding length of the coupling portion 32 is not lengthened. In addition, since the actuator 30 is pressurized toward the closed position direction, the actuator 30 does not open (move to the open position). In particular, since the contact portion 33 according to the present embodiment sandwiches the FPC / FFC 50 together with the contact portion 21 of the contact 20, the coupling portion 32 is formed by the FPC / FFC 50. It is configured to always contact the upper surface 50a of the FPC / FFC 50 when the actuator 30 is in the closed position as well as when the engaged portion 54 is engaged.

9 and 10, the receiving portion 34 is formed in a slit shape parallel to the XZ plane. This accommodating part 34 partially accommodates the maxillary part 23 of the contact 20, as shown to FIG. 3 and FIG.

As shown in Figs. 3, 6 and 10, the lift up portion 35 has an eccentric shape, and the inner walls constituting the accommodating portion 34 in each accommodating portion 34 are Y. It is connected in the direction. That is, the lift up part 35 is located in the accommodating part 34. The lift up part 35 lifts up the upper part 23 of the contact 20 in the accommodating part 34 in accordance with a rotation operation of rotating the actuator 30 from the open position to the closed position. (See Fig. 6). When the lift up part 35 lifts up the upper part 23, the contact part 21 formed in the lower part 22 is displaced upwards as mentioned above.

As shown in FIGS. 6 and 10, the enclosure portion 36 constitutes a rear portion of the actuator 30 when the actuator 30 is in the closed position, and the rear end 10b of the housing 10. Surround the top of the. By this enclosing, the upper part of the to-be-supported part 25 of the contact 20 is also protected and surrounded.

As shown in Fig. 3, the FPC / FFC 50 is inserted when the actuator 30 is in the open position with respect to the insertion port 4 of the connector 1 having the above-described configuration. It is set as shown. At this time, the coupling part 32 is located above the recess 53 of the FPC / FFC 50. In this state, when the actuator 30 is rotated toward the closed position, as shown in Fig. 6, the upper portion 23 of the contact 20 is lifted by the lift up portion 35, whereby the contact portion 21 ) Is displaced upward. As a result, the FPC / FFC 50 is sandwiched between the contact portion 33 and the contact portion 21, and electrical connection between the contact portion 21 and the contact portion 52 is also achieved. At this time, as shown in Fig. 7, the engaging portion 32 is located in the recess 53, so that the above-described fall prevention is realized.

As mentioned above, although embodiment was mentioned and this invention was concretely demonstrated, this invention is not limited to this.

For example, in the above-described embodiment, since the FPC / FFC 50 is sandwiched between the contact portion 33 and the contact portion 21, the contact portion 33 is in the closed position. Is in contact with the top surface 50a of the FPC / FFC 50. However, a contact object other than the contact 20 or an elastic body may be formed such as a press object other than the contact part 33. In this case, the contact part 33 prevents the undesirable rotation of the actuator 30. In this case, it is preferable that the FPC / FFC 50 is in contact with each other, and the actuator 30 is not necessarily in contact with the FPC / FFC 50 when the actuator 30 is in the closed position.

In addition, the FPC / FFC 50 which can be connected to the connector 1 includes recesses 53 at both left and right ends. However, for example, as shown in FIG. The FPC / FFC 50 'provided may be the connection target. In this case, the edge of the convex part 55 which is far from the edge part 51 functions as the to-be-engaged part 56.

Although the best embodiment of this invention was described, it is possible for an embodiment to be modified in the range which does not deviate from the mind of this invention, as obvious to a person skilled in the art, and such embodiment is a thing of the scope of this invention. .
