Description

The present invention relates to a cable connector, and more particularly, to a rotary connector that opens and closes an actuator in a cable connector suitable for connecting a cable such as an FPC (Flexible Printed Circuit) or FFC (Flexible Flat Cable) to a substrate. The present invention relates to a cable connector.

  This type of cable connector has a housing (insulator) for receiving a cable having one surface and the opposite surface such as FPC and FFC, a contact portion facing one surface of the cable, and a pivot portion facing the opposite surface. A plurality of contacts that are fixedly held at a pitch of 5 mm, and an open position that receives the cable in the housing and an actuator that is rotatable between a closed position that presses the received cable in the contact portion direction (for example, “Patent Documents 1 to 3” 6 ").

  In addition, the front end portion of the pivot portion has a concave portion opened downward, and a hook-shaped hook portion is formed at the front end. On the other hand, the hook portion is fitted into the base end portion of the actuator from above and adjacent to the groove portion. It is well known that an engaging cam portion that is fitted into the concave portion from below and is positioned between the pivot support portion and the cable is formed, and the actuator is rotated with the tip end portion of the pivot support portion as the rotation center ("Patent Documents 1 to 3"). "reference.). In addition, temporary holding of the cable inserted into the housing is performed at the contact portion between the engagement cam portion of the actuator and the contact (for example, “Patent Document 1”), and the two types of first and second contacts are provided. Arranged alternately at a predetermined pitch in the longitudinal direction of the housing, the first contact portion of the first contact and the second contact portion of the second contact are arranged in a staggered manner in two rows before and after the inlet side and the rear side of the housing. In such a cable connector, the first contact portion and the second contact portion are alternately arranged on both sides of the rotation axis of the actuator, and the rotation moment around the rotation axis of the actuator by the first and second contact portions is reduced. The sum adds a moment to rotate the actuator in the closed position direction (see, for example, “Patent Document 2”), and the first and second contact portions arranged in a staggered manner. The height of the contact part on the inlet side arranged on the inlet side of the housing is made lower than the height of the contact part on the back side arranged on the back side, and the temporary holding of the cable inserted in the housing is performed with the back side contact part. It is also well known that the temporary holding portion of the housing is used and the cable is not temporarily held at the inlet side contact portion (see, for example, “Patent Document 3”).

Furthermore, it is also well known that the groove portion adjacent to the engagement cam portion of the actuator is a through hole and the actuator is rotated about the engagement cam portion as a rotation center (see, for example, “Patent Documents 4 to 6”).
Japanese Patent No. 3023442 Japanese Patent No. 3096891 Japanese Patent No. 3069634 Japanese Patent No. 3430398 Japanese Patent No. 3278742 Japanese Patent No. 3295808

In a conventional cable connector, one of the first and the contact pressure of the second contact portion, although one contact pressure acts as a moment that rotates the actuator in the closed position direction and the other contact pressure rotary actuator to the open position direction Since the moment that rotates the actuator in the direction of the closed position is small, the holding force at the closed position of the actuator cannot be secured sufficiently, and the actuator may be opened carelessly when the cable is connected. In order to prevent this, the contact pressure that acts as a moment for rotating the actuator in the closed position direction needs to be much larger than the contact pressure that acts as a moment for rotating the actuator in the open position direction. A cable such as FPC or FFC cannot be inserted into the housing due to a large contact pressure.

  In the conventional cable connector, the engagement cam portion of the actuator is positioned between the pivot portion of the contact and the cable, and when the actuator is closed, the cable is pressed toward the contact portion by the engagement cam portion. The base end portion including the engagement cam portion is merely engaged with the distal end of the pivotal support portion so that the base end portion cannot be fitted, and there is a drawback that the actuator is easily detached. In order to solve this drawback, if the pivot shafts protruding from the left and right ends of the actuator are only fitted to the bearings formed at the left and right ends of the housing, the cable will be deformed when the actuator is closed. The contact portion of each contact cannot be pressed with an equal force, and contact reliability cannot be ensured. Further, when the actuator is rotatably supported by the shaft passing through the base end portion, the bending deformation when the actuator is closed is prevented, but the number of parts of the connector and the number of assembling steps are increased, resulting in an increase in cost.

  The present invention has been made in view of the above circumstances, and a first object of the present invention is to provide a rotary cable connector for opening and closing an actuator without increasing the contact pressure of the contact portion of the contact more than necessary. It is intended to secure a sufficient holding force in the closed position of the actuator and prevent the actuator from being inadvertently opened when the cable is connected.

  Secondly, in the rotary cable connector that opens and closes the actuator, the base end of the actuator is fitted and supported by the pivot of the contact so that the contact reliability cannot be ensured and the cost is increased. This eliminates the drawbacks of the conventional cable connector that the actuator is easily disconnected without causing other problems such as inconvenience, and prevents the assembly of the connector, in particular, the mounting of the actuator from becoming difficult. .

In order to achieve the above object, the present invention
(A) A cable connector for receiving a cable having one surface and an opposite surface, the contact having a contact portion facing the one surface and a pivot portion facing the opposite surface, and the contact being predetermined A cable connector having a housing that is inserted and held in a direction, and an actuator that is rotatable between an open position for receiving the cable in the housing and a closed position for pressing the cable received in the housing in the contact portion direction;
(B) The contact includes first and second contacts that are inserted and held in the housing from the first and second directions that have the first and second contact portions and the first and second pivot portions and are in conflict with each other.
(C) The first and second contact portions of the first and second contacts are arranged on one side of the rotational axis of the actuator so that a moment for rotating the actuator in the closed position direction is applied to the actuator. It arrange | positions to one side and is characterized by the above-mentioned.

  According to the present invention, since only the moment for rotating the actuator in the closed position direction is applied to the actuator, the actuator can be held closed with a larger moment than the conventional cable connector. In addition, the actuator can be closed and held with a greater moment than the conventional cable connector without increasing the contact pressure by the first and second contact portions.

In the present invention, (d) when the actuator is in the open position, the cable inserted into the housing is pressed and temporarily held by the first pivot portion at the first contact portion of the first contact. With
(E) It is preferable that the second contact portion of the second contact is pressed and temporarily held by the temporary holding portion of the housing (claim 2).
As described above, the first and second contact portions do not temporarily hold the cable between the actuator and the actuator, so that the opening / closing operation force of the actuator can be reduced as compared with the conventional cable connector. This is effective because it can be improved.

(F) The first contacts and the second contacts are alternately arranged at a predetermined pitch in the longitudinal direction of the housing;
(G) The first contact portion and the second contact portion are arranged in a staggered manner in two rows before and after the inlet side and the back side of the housing,
(H) The height of the first contact portion on the inlet side is set lower than the height of the second contact portion on the back side,
(I) The first contact portion on the inlet side is set to a height at which the first pivot portion can be pressed when the cable is inserted,
(J) It is preferable that the second contact portion on the back side is set to a height that can be pressed against the temporary holding portion of the housing when the cable is inserted.
As described above, the first and second contact portions do not temporarily hold the cable between the actuator and the actuator, so that the opening / closing operation force of the actuator can be reduced as compared with the conventional cable connector. This is effective because it can be improved. In addition, before inserting the end of the cable between the second contact portion on the back side and the temporary holding portion of the housing, the vicinity of the end of the cable is temporarily connected with the first contact portion and the first pivot portion on the inlet side. By holding, the end of the cable can be properly inserted between the second contact portion on the back side and the temporary holding portion of the housing, which is effective.

Furthermore, (k) an engaging protrusion is formed at the tip of both end faces of the actuator,
(L) It is preferable that the housing is formed with an engaging groove for engaging the engaging protrusion when the actuator is rotated to the closed position.
Thus, providing the locking means at the closed position of the actuator is effective because the actuator can be reliably closed and held as compared with the conventional cable connector.

Further, (m) the first pivotal support has a recess opened upward on the side opposite to the cable, and has a hook-shaped hook portion at the tip,
(N) The actuator includes a hook-shaped first groove portion into which the hook portion is fitted from below, and a vertical groove portion in which an end of the hook-shaped first groove portion is closed, and the concave portion from above. A first cam portion to be fitted is formed,
(O) the second pivotal support has a linear portion at the tip so as to close the opening of the recess when viewed from the direction of the rotation axis of the actuator;
(P) The actuator includes a hook-shaped second groove portion into which the linear portion is fitted, and a vertical groove portion that is a through-hole of the hook-shaped second groove portion. A second cam portion located between the two is formed,
(Q) It is preferable that the base end portion of the actuator forming the first and second cam portions is rotatably surrounded and sandwiched by the first and second pivot portions of the first and second contacts. .

In this manner , the base end portions of the actuators forming the first and second cam portions are surrounded and sandwiched by the first and second pivot support portions of the first and second contacts so as to be rotatable. In other words, the base end portion of the actuator is fitted and supported rotatably by the pivot portion of the contact. For this reason, the disadvantage of the conventional cable connector that the actuator is easily detached can be solved without causing other problems such as failure to ensure contact reliability and increase in cost.

  Further, in assembling the connector, first, the first contact is inserted into the housing from the first direction and held, and then the base end portion of the actuator is put on the first pivotal support portion from above. As a result, the first cam portion of the actuator is fitted into the recess of the first pivot portion, and at the same time, the hook portion of the first pivot portion is fitted into the first groove portion of the actuator. Next, the second contact is inserted and held in the housing from the second direction. Thereby, the linear part of the 2nd pivot part fits in the 2nd groove part of an actuator, and is located above the 2nd cam part. This completes the assembly of the connector that fits and supports the base end portion of the actuator so as to be rotatable by the pivot portion of the contact. Thus, the assembly of the connector, in particular, the mounting of the actuator does not become difficult.

Furthermore, in the conventional cable connector, the pivot part of the contact is elastically displaced at the time of assembly more than when the connector is used (when the cable is connected), and the contact is damaged or the elasticity of the pivot part is lowered. However, in the present invention, there is no risk of elastic displacement of the contact pivot when the connector is assembled. Therefore, the contact is damaged or the elasticity of the pivot is reduced. Generation of defective products can be prevented.

  As is apparent from the above, according to the present invention, in the rotary cable connector that opens and closes the actuator, the holding force at the closed position of the actuator is sufficiently increased without increasing the contact pressure of the contact portion more than necessary. And inadvertent opening of the actuator when the cable is connected can be prevented.

  Further, according to the present invention, in the rotary type cable connector that opens and closes the actuator, the base end of the actuator can be rotatably fitted and supported by the pivot of the contact, and contact reliability cannot be ensured. This eliminates the drawbacks of the conventional cable connector that the actuator is easily disconnected without causing other problems such as cost and cost increase, and at that time, it is not difficult to assemble the connector, in particular, to install the actuator. Has the advantage.

At the same time, the hook portion 4h of the first pivotal support 4b is fitted into the first groove 6c of the actuator 6 from below. Next, one second contact 5 is inserted and implanted in each second hole 3 g of the housing 3 from the second direction B, and fixedly held inside the housing 3. Accordingly, the first contacts 4 and the second contacts 5 are alternately arranged along the longitudinal direction of the housing 3. At this time, along with the insertion of the second contact 5, the linear portion 5g of the second pivotal support portion 5b is fitted into the second groove portion 6g of the actuator 6 and is positioned on the upper side of the second cam portion 6h. This completes the assembly of the connector 1 that rotatably fits and supports the base end portion of the actuator 6 in the bearing hole 8 formed by the first and second pivot portions 4b and 5b of the first and second contacts 4 and 5. Thus, the connector 1 shown in FIGS. 1 and 4 to 9 can be obtained.

Next, a method for using the connector 1 configured as described above will be described.

The connector 1 is surface-mounted on the substrate, so that the soldering portion 4j of the first contact 4 and the soldering portion 5h of the second contact 5 are soldered and electrically connected to the conductor of the substrate. Fixed. In order to connect the cable 2 to the connector 1, first, as shown in FIGS. 1, 4, and 6, the actuator 6 in the closed position is moved upward with the cable 2 positioned in front of the connector 1. And the cable receiving portion 3a of the housing 3 can receive the cable 2 as shown in FIGS. From this state, the end of the cable 2 is inserted into the cable receiving portion 3a. The cable 2 inserted into the cable receiving portion 3a is firstly connected between the base end portion of the contact arm 5f of the second contact 5 and the second cam portion 6h of the actuator 6 and the first contact portion 4a of the first contact 4 and the first contact portion 4a. It passes between the 1 pivotal support part 4b substantially simultaneously. At this time, since the distance between the base end portion of the contact arm 5f of the second contact 5 and the second cam portion 6h of the actuator 6 is larger than the thickness dimension of the cable 2, the cable 2 is pressed in the thickness direction. Without passing, that is, without being temporarily held, it passes between the base end of the contact arm 5f of the second contact 5 and the second cam portion 6h of the actuator 6, but the first contact of the first contact 4 Since the distance between the portion 4a and the first pivot portion 4b is smaller than the thickness dimension of the cable 2, the cable 2 passes through with the downward elastic displacement of the first contact portion 4a and the contact arm 4f. Become. Thereby, the cable 2 is pressed by the 1st contact part 4a by the 1st pivot part 4b, and is temporarily hold | maintained between the 1st contact part 4a and the 1st pivot part 4b. Next, the cable 2 passes between the second contact portion 5 a of the second contact 5 and the temporary holding portion 3 h of the housing 3. At this time, the distance between the second contact portion 5a of the second contact 5 and the temporary holding portion 3h of the housing 3 is smaller than the thickness dimension of the cable 2 and there is no gap. The two contact portions 5a and the contact arms 5f pass with downward elastic displacement. Accordingly, the cable 2 is pressed against the temporary holding portion 3h of the housing 3 by the second contact portion 5a, and is temporarily held between the second contact portion 5a and the temporary holding portion 3h of the housing 3. After the cable 2 passes between the second contact portion 5a of the second contact 5 and the temporary holding portion 3h of the housing 3, the end reaches the innermost portion of the cable receiving portion 3a, and the first contact portion 4a and the first contact portion 4a It is received by the cable receiving portion 3a of the housing 3 in a state of being temporarily held at two places between the one pivotal support portion 4b and between the second contact portion 5a and the temporary holding portion 3h of the housing 3.

  4 to 9, the actuator 6 is pivoted counterclockwise in the cable receiving state, and the proximal end portion of the actuator 6 including the pivot shafts 6a at the left and right ends and the first cam portion 6d and the second cam portion 6h therebetween. 1, 5, 7, and 9, and is laid in a substantially horizontal posture at the open position accommodated in the upper opening 3 b of the housing 3, and enters the cable receiving portion 3 a. The upper opening 3 b that opens approximately half of the side above the housing 3 is closed. As a result, the cable 2 is pressed downward on the inner end face of the second cam portion 6h biased downward by the cable pressing portion 6n on the inner surface of the actuator 6, that is, the linear portion 5g of the second pivotal support portion 5b. As a result, the first contact portion 4a of the first contact 4 moves downward with further downward elastic displacement of the contact arm 4f, and the conductor of the cable 2 is pressed against the first contact portion 4a with a predetermined contact pressure. Electrical connection is obtained, and the second contact portion 5a of the second contact 5 is pressed into contact with the second contact portion 5a at a predetermined contact pressure in a cable receiving state to obtain an electrical connection, and a cable connection state is obtained. This cable connection state is maintained by the closed holding (locking in the closed position) of the actuator 6 by the engagement between the engagement protrusion 6b of the actuator 6 and the engagement groove 3e provided in the lock piece 3d of the housing 3.

  As is clear from the above, the cable connector 1 is a cable connector for receiving the cable 2 having one surface and the opposite surface, and the contact portions 4a, 5a facing the one surface and the pivot facing the opposite surface. Contacts 4 and 5 having support portions 4b and 5b, a housing 3 for inserting and holding the contacts 4 and 5 in predetermined directions A and B, an open position for receiving the cable 2 in the housing 3, and the housing 3 and an actuator 6 that can rotate between closed positions for pressing the cable 2 received in the direction of the contact portions 4a and 5a.

  The contacts 4 and 5 are inserted into the housing 3 from the first and second directions A and B, which have the first and second contact portions 4a and 5a and the first and second pivot portions 4b and 5b and are opposite to each other. The first and second contacts 4a, 5a of the first and second contacts 4, 5 are both moments for rotating the actuator 6 in the closed position direction. To the actuator 6 so as to be shifted to one side of the rotational axis O of the actuator 6. According to this, since only the moment for rotating the actuator 6 in the closed position direction is applied, the actuator 6 can be held closed with a larger moment than the conventional cable connector. In addition, the contact pressure by the first and second contact portions 4a and 5a can be kept closed with a larger moment as compared with the conventional cable connector without increasing the contact pressure. For this reason, in the rotary cable connector 1 that opens and closes the actuator 6, the holding force at the closed position of the actuator 6 is sufficient without increasing the contact pressure of the contact portions 4a and 5a of the contacts 4 and 5 more than necessary. And inadvertent opening of the actuator 6 when the cable is connected can be prevented.

  When the actuator 6 is in the open position, the cable 2 inserted into the housing 3 is pressed and temporarily held by the first pivot portion 4b by the first contact portion 4a of the first contact 4. At the same time, the second contact portion 5 a of the second contact 5 is pressed and temporarily held by the temporary holding portion 3 h of the housing 3. As described above, the first and second contact portions 4a and 4b do not temporarily hold the cable 2 between the first and second contact portions 4a and 4b, so that the opening / closing operation force of the actuator 6 can be increased as compared with the conventional cable connector. The size can be reduced, and the operability can be improved.

  The first contacts 4 and the second contacts 5 are alternately arranged at a predetermined pitch in the longitudinal direction of the housing 3, and the first contact portions 4 a and the second contact portions 5 a 3, the first contact portion 4a on the entrance side is set to be lower than the height of the second contact portion 5a on the back side. The first contact portion 4a on the entrance side is set to a height that can be pressed against the first pivotal support portion 4b when the cable is inserted, and the second contact portion 5a on the back side is set when the cable is inserted. The height is set such that the temporary holding portion 3h of the housing 3 can be pressed. As described above, the first and second contact portions 4a and 5a do not perform the temporary holding function of the cable 2 between the actuator 6 and the opening / closing operation force of the actuator 6 compared to the conventional cable connector. The operability can be improved. Before inserting the end of the cable 2 between the second contact portion 5a on the back side and the temporary holding portion 3h of the housing 3, the first contact portion 4a and the first pivot portion 4b on the entrance side By temporarily holding the vicinity of the end of the cable 2, the end of the cable 2 can be properly inserted between the second contact portion 5 a on the back side and the temporary holding portion 3 h of the housing 3.

  An engagement protrusion 6b is formed at the tip of both end faces of the actuator 6, and the housing 3 is engaged to engage the engagement protrusion 6b when the actuator 6 is rotated to the closed position. A groove 3e is formed. Thus, by providing the locking means at the closed position of the actuator 6, the actuator 6 can be reliably closed and held as compared with the conventional cable connector.

Further, the contacts 4 and 5 are inserted into the housing 3 from the first and second directions A and B which have the first and second contact portions 4a and 5a and the first and second pivot portions 4b and 5b and are opposite to each other. The first pivot portion 4b includes first and second contacts 4 and 5 to be held, and the first pivot portion 4b has a concave portion 4g that opens upward on the side opposite to the cable 2 and has a hook-shaped hook portion 4h at the tip. The actuator 6 has a hook-shaped first groove portion 6c into which the hook portion 4h is fitted from below, and a vertical groove portion where the end portion of the hook-shaped first groove portion 6c is closed to the concave portion 4g. A first cam portion 6d fitted from above is formed, and the second pivotal support portion 5b is a linear portion at the tip so as to close the opening of the recess 4g when viewed from the direction of the rotation axis O of the actuator 6. 5g, the actuator 6 has Between the linear portion 5g and the cable 2 formed adjacent to the vertical groove portion which is a through-hole of the hook-shaped second groove portion 6g and the vertical groove portion 6g into which the linear portion 5g is fitted. The second cam portion 6h is formed, and the base end portion of the actuator 6 forming the first and second cam portions 6d, 6h is used as the first and second pivots of the first and second contacts 4,5. The support parts 4b and 5b are surrounded and pinched so as to be rotatable. Thus, the base end portion of the actuator 6 forming the first and second cam portions 6d, 6h is surrounded by the first and second pivot portions 4b, 5b of the first and second contacts 4, 5 so as to be rotatable.・ Pinch. In other words, the base end portion of the actuator 6 is rotatably fitted and supported by the pivot portions 4b and 5b of the contacts 4 and 5. For this reason, it is possible to eliminate the drawbacks of the conventional cable connector that the actuator 6 is easily detached without causing other problems such as failure to ensure contact reliability and increase in cost. In assembling the connector 1, first, the first contact 4 is inserted and held in the housing 3 from the first direction A, and then the base end portion of the actuator 6 is put on the first pivotal support portion 4 b from above. As a result, the first cam portion 6d of the actuator 6 is fitted into the recess 4g of the first pivot portion 4b, and the hook portion 4h of the first pivot portion 4b is fitted into the first groove portion 6c of the actuator 6 at the same time. Next, the second contact 5 is inserted into the housing 3 from the second direction B and held. Thereby, the linear part 5g of the 2nd pivotal support part 5b fits in the 2nd groove part 6g of the actuator 6, and is located above the 2nd cam part 6h. Thus, the assembly of the connector 1 for fitting and supporting the base end portion of the actuator 6 so as to be rotatable by the pivot portions 4b and 5b of the contacts 4 and 5 is completed. Thus, the assembly of the connector 1, in particular, the attachment of the actuator 6 does not become difficult. Furthermore, in the conventional cable connector, the pivot part of the contact is elastically displaced at the time of assembly more than when the connector is used (when the cable is connected), and the contact is damaged or the elasticity of the pivot part is lowered. There is a possibility that a defective product in which the contact pressure cannot be obtained properly can be generated. However, since the pivotal support portions 4b and 5b of the contacts 4 and 5 are not elastically displaced when the connector is assembled by the above configuration, Generation | occurrence | production of the inferior goods by damage and the elastic fall of the pivot parts 4b and 5b can be prevented. Thus, in the rotary cable connector 1 that opens and closes the actuator 6, the base end portion of the actuator 6 can be rotatably fitted and supported by the pivot portions 4 b and 5 b of the contacts 4 and 5. Can be eliminated, and the disadvantage of the conventional cable connector that the actuator 6 is easy to come off can be eliminated without causing other problems such as inconvenience and cost increase. Installation of the actuator 6 does not become difficult.

  Incidentally, in the cable connector 1 shown in the present embodiment, the actuator (operator) 6 is formed so as to penetrate the cam portion 6h located between the pivot portion and the cable and adjacent to the cam portion 6h. The pivot portion 5b does not have a recess and is not engaged with the cam portion 6h.

  The actuator (operator) 6 can be rotated between an open position and a closed position where the cable inserted into the housing (insulator) 3 is held in pressure contact with the contact. The cable inserted into the housing (insulator) 3 is not temporarily held in cooperation with the contact.

  Further, a plurality of contacts 4, 5 are provided, but the contact portions 4 a, 5 a are not arranged on both sides of the pivot shaft 6 a (rotation axis O) of the actuator (operator) 6.

  Moreover, although the pivot part has the hook part 4h at the tip, the actuator 6 is not formed with a through hole into which the pivot part having the hook part 4h is inserted.

  Of the contacts arranged in a staggered pattern, the height of the inlet side contact 4 arranged on the cable inlet side of the housing (insulator) 3 is set to be lower than the height of the back side contact 5, Although the cable is held in cooperation with the housing at the time of insertion, the height of the inlet side contact is not set to a height that does not contact the cable when the cable is inserted.

  Among the contacts arranged in a staggered manner, the height of the inlet side contact 4 arranged on the cable inlet side of the housing (insulator) 3 is set lower than the height of the back side contact 5. No step is provided on the separation wall 3i (see FIGS. 2, 4 to 7) of the housing that is isolated in the pitch direction of the back side contact 5.
