    [0001] LEVER TYPE CONNECTOR In its field, the invention relates to a lever type connector. In the prior art, Japanese Unexamined Patent Publication No. 2004-164933 discloses a connector that uses a lever to produce a cam action that reduces a connection effort. The lever is rotatably mounted on a connector housing and has a cam groove which is coupled to a cam pin on a conjugate connector. An initial latch holds the lever at an initial position, but is released when the lever type connector is partially connected to the conjugate connector so that the lever can be rotated. Rotation of the lever from the initial position to an end of connection position causes the connector to the conjugate connector to reach a properly connected state. The connector housing described above may be pushed further in the connection direction after the lever-type connector has been partially connected to the mated connector to release the initial lock. Thus, the housing can move slightly forward and the lever can turn weakly even if the lever is not controlled. Then, an operator may misinterpret the fact that a connection operation on the conjugate connector has been completed and the connector may be left incompletely connected. The invention has been made on the basis of the foregoing situation and has the objective of creating a lever-type connector to avoid misinterpretation that a connection operation on a conjugate connector 3032833 has been completed. In summary, the invention relates to a lever-type connector with a lever having a cam groove for coupling to a cam pin arranged on a conjugate connector. The connector has a housing and the lever is rotatably mounted thereon. An initial lock holds the lever at an initial position. However, the initial lock is released to allow a lever rotation operation when the lever-type connector is temporarily connected to the conjugate connector. The lever-type connector is properly connected to the mating connector by rotating the lever from the home position to a connecting end position. The lever and the housing have rotation control portions arranged separately from the initial lock. The rotation control portions regulate the rotation of the lever by being held in contact with each other in the direction of rotation of the lever when the lever is in the initial position. A stop portion is arranged near an inlet of the cam groove and abuts against the cam pin if the housing is pushed in the connection direction to the conjugate connector when the lever is in the initial position. This coupling of the stop portion of the cam groove against the cam pin prevents thrust of the housing toward the conjugate connector. Thus, the rotation of the lever is regulated by the rotation control portions, and an operator can not mistakenly consider that a connection operation to the conjugate connector has been completed. The lever-type connector may be such that the lever turns weakly accompanying the release of the initial lock. The rotation control portions are separated when the initial lock is activated and come into contact with each other after the rotation of the lever accompanying the release of the initial lock. Therefore, a lever rotation force that accompanies the release of the initial latch does not act on the rotation control portions. The rotational control portion on the housing or on the lever may be resiliently displaced by an increase in contact force by the lever rotation operation, thereby releasing a state in which the rotation of the lever is regulated. Therefore, the state in which the rotation of the lever is regulated is released by an increase in a lever rotational effort. Thus, this release operation and the lever rotation operation can be implemented as a series of operations. The drawings will now be briefly described.

Fig. 9 is a partially sectional plan view showing a state correctly connected to the conjugate connector. A specific embodiment of the invention is described in detail with reference to Figs. 1-9. A connector C in this embodiment is a lever-type connector which can be connected to a conjugate connector 30 and separated from it by rotation of a lever 10. A connecting surface of each member is referred to herein as the front, and upper and lower faces in Fig. 1 are referred to as the top and the bottom. Conjugate connector 30 is a printed circuit board connector and includes a conjugate housing 31 made of a synthetic resin and a plurality of conjugate male terminal connectors 32. As shown in FIG. Conjugate 31 has open containers 3032833 to front 33 and connector C is assembled in each of receptacles 33. Receptacles 33 are arranged side by side in a lateral direction as shown in FIG. 3. Conjugated terminal connectors 32 are mounted such that tip portions thereof extend into each receptacle 33. A cylindrical cam pin 34 extends downward from the top wall of each receptacle 33 and to an internal space of the receptacle 33. Receptacle 33. The cam pin 34 is substantially centrally disposed in a longitudinal direction of the receptacle 33. A lock release portion 35 extends from the top wall of each receptacle 33, as shown in FIG. 3, to release an initial lock L of the lever 10. As shown in FIGS. 7 and 8, the lock release portion 35 extends directly in the longitudinal direction from the front end to the rear end of the receptacle 33. As shown in FIG. 6, the connector C includes the lever 10 and a housing 20. The lever 10 comprises a cam groove 11 to be coupled to the cam pin 34 on the conjugate connector 30. The housing 20 includes the rotatably mounted lever 10 and the initial lock L to hold the lever 10 to an initial position. The lock release portion 35 releases the initial lock L afm to allow rotation of the lever 10 when the connector C is partially connected to the conjugate connector 30. The lever 10 is then rotated from the initial position to a position of end of connection and drives the connector C to the conjugate connector 30 to reach a properly connected state. The housing 20 is made of a synthetic resin and, as shown in FIG. 1, is made in a substantially rectangular block shape to assemble in the receptacle 33 of the conjugate housing 31. The housing 20 has a portion receiving terminal 21 for receiving unrepresented terminal connections and a lever receiving portion 22 for receiving the lever 10.
    [0002] As shown in Fig. 2, the terminal receiving portion 21 includes a retaining member 23 for locking the terminal connections.
    [0003] The lever receiving portion 22 is open rearwardly so that the lever 10 can be assembled from the front. The lever receiving portion 22 is sized to extend substantially over the entire upper surface of the first housing 12, as shown in FIGS. 6-9.
    [0004] As shown in Fig. 7, the lever receiving portion 22 includes a first receiving path 24 for receiving the cam pin 34 of the conjugate connector 30 from the front and a second receiving path 25 for receiving the lock release portion 35 from the front. The first reception path 24 is located in a substantially central portion of the housing 20 in the transverse direction and the second reception path 25 is located on a first side of the housing 20 in the transverse direction. The lever 10 is a rotating lever and has a thin flat cam plate 12 made of a synthetic resin and a controllable control portion 13 by placing the finger on it to rotate the lever 10, as shown on Figure 4. The cam plate 12 of the lever 10 is mounted in the lever receiving portion 22 with a narrow clearance, as shown in Figure 6, and the control portion 13 extends rearwards to According to FIG. 4, a substantially circular bearing hole 14 is hollowed out on the lower surface of the cam plate 12. A support shaft (not shown) extends over the lever receiving portion 22 of the housing 20 and is assembled in this bearing port 14. The lever 10 is rotatable about the support shaft between an initial position shown in Fig. 6 in which the lever 10 is held before coupling the conjugate connector 30 and an end-of-connection portion shown in FIG. 9 in which the correct connection of the conjugate connector 30 is completed. It may be noted that the lever 10 has a connecting latch piece 17 for holding the lever 10 at the connecting position fm. A cam groove 11 is formed on the upper surface of the cam plate 12, as shown in FIGS. 7 to 9, and can be coupled to the cam pin 34 of the conjugate connector 30. The cam groove Cavity form 11 extends from the outer peripheral surface of cam plate 12 to the center. When the lever 10 is in the initial position, the input of the cam groove 11 is on the first reception path 24 and the cam pin 34 can be received in the cam groove 11.
    [0005] A stop portion 19 is arranged near the inlet of the cam groove 11 to abut against the cam pin 34 if the housing 20 is pushed forward in the connecting direction to the conjugate connector. When the lever 10 is in the initial position. The abutment portion 19 is formed on a side surface of the cam groove 11 and is inclined with respect to a longitudinal direction of the cam groove 11 so as to open. This causes the inlet of the cam groove 11 to have a greater width than a portion behind the entrance. The abutment portion 19 is substantially at right angles to the longitudinal connection direction when the lever 10 is in the initial position.
    [0006] The connector C has the initial lock L to keep the lever 10 in the initial position (see FIG. 6). The initial lock L comprises an initial lock piece 15 arranged on the lever 10 and a lock receiving portion 26 arranged on the housing 20. The initial lock piece 15 is cantilevered from the surface 20 external device of the cam plate 12 and extends in the direction of rotation of the lever 10 from the initial position to the end of connection position. A base end portion of the initial latch piece 15 is located near the entrance of the cam groove 11. A latch portion 16 to be latched to the latch receiving portion 26 is disposed on a tip portion of the initial latch piece 15. The latch receiving portion 26 extends rearward of the second receiving path 25 at a position near the trailing end of the latch receiving portion 22. When the lever 10 is in the initial position, the locking portion 16 of the initial lock piece 15 is located on the second receiving path 25 and is locked on the front surface of the lock receiving portion 26 to regulate the rotation of the lever 10 to the end position of 3032833 connection. The connector C comprises, separately from the initial lock L, rotation control portions S to regulate the rotation of the lever 10 while being kept connected to the lever 10 in the direction of rotation of the lever 10 when the lever 10 is in position. the initial position (see Figures 6 and 7). The rotation control portions S have a lever-side control portion 18 on the lever 10 and a housing-side control portion 27 on the housing 20. The control portion of the lever-side 18 is arranged at a position on the plate The control portion of the lever member 18 extends over the outer peripheral surface of the cam plate portion 12. A cam 12 of the lever 10 opposes the initial lock piece 15 through the bearing port 14. front surface of the lever-side regulating portion 18 in the direction of rotation of the lever 10 from the initial position to the connecting-fm position is substantially vertical with respect to the outer peripheral surface of the cam plate 12. In addition, a rear surface of the lever-side regulating portion 18 is inclined to gradually increase a projection distance from the rear to the front in the direction of rotation. The housing-side regulating portion 27 extends on a side wall of the lever receiving portion 22. The housing-side regulating portion 27 is located on a stroke of the lever-side regulating portion 18 when the lever 10 is turned. The rear surface of the housing-side regulating portion 27 is substantially perpendicular to the longitudinal direction. A portion of the side wall of the housing 20 in which the housing-side regulating portion 27 extends defines an elastic displacement portion 28 which can be resiliently displaced in the lateral direction in FIG. elastic 28 is separated from the other side of the side wall of the housing 20 by slots 29 formed above and below, as shown in Figure 2, and is cantilevered from the front rearward. The housing-side regulating portion 27 is provided on a rear end portion of the resilient displacement portion 28, as shown in FIG. 6. The resilient displacement portion 28 is arranged to protrude into a protrusion 3032833 from the side surface of the housing 20 in a natural state. The connector C is connected to the conjugate connector 30 first by placing the lever 10 at the initial position (see FIG. 6). When the lever 10 is in the initial position, the initial lock L is in an operational state. At this time, the control portion of the lever side 18 and the control portion of the housing side 27 are opposite each other (separated) in the direction of rotation of the lever 10. Next, the connector C is assembled in the receptacle 33 of the conjugate connector 30 (see FIG. 7). Thus, the cam pin 34 enters through the inlet of the cam groove 11 from the first reception path 24 and the abutment portion 19 of the cam groove 11 and the cam pin 34 abut the against each other in the longitudinal direction. Further, the lock releasing portion 35 enters from the second receiving path 25 and presses the initial latch piece 15 in an unlocking direction to resiliently move the original latch member 15. In this manner, The locking portion 16 is decoupled from the lock release portion 35 to release a locked state and a rotation operation of the lever 10 to the home position is allowed. The lever 10 rotates slightly during this release of the initial lock L. Then, the control portion of the lever side 18 and the regulating portion of the housing side 27 are brought into contact with each other.
    [0007] An operator can push hard on the rear surface of the housing 20 in a force to push the connector C into the receptacle 33 of the conjugate connector 30 without rotating the lever 10. However, the cam pin 34 abuts the portion 19 of the cam groove 11 in the longitudinal direction to prevent a thrusting movement of the housing 20. In addition, the control portion of the lever side 18 and the regulating portion of the housing side 27 are in contact with each other. with the other in the direction of rotation to regulate the rotation of the lever 10. The connection does not occur and the lever 10 also does not rotate even if the rear surface of the housing 20 is pushed Thus, an operator is not going not mistakenly consider that the splicing operation has been completed, and realizes that the connector C can not be connected to the conjugate connector 30 unless the lever 10 is rotated.
    [0008] 3032833 If the operator attempts to turn the lever 10 to the end of connection position by pressing the control portion 13 of the lever 10, a contact force between the control portion of the lever side 18 and the regulating portion of the housing side 27 increases and the elastic displacement portion 28 of the housing 20 is outwardly resiliently displaced, the housing-side regulating portion 27 is retracted outward and a rotational-regulating state of the rotation-regulating portions S is released as shown in Fig. 8. As the operator rotates the lever 10, the lever-side control portion 18 passes through the inner side of the housing-side regulating portion 27 and the moving portion. resilient 28 resiliently returns to an initial position. In addition, the cam pin 34 is cut from the abutment portion 19 and the connector C is driven to a conjugate side by a cam action by coupling the cam pin 34 and the cam groove 11. Thus, the connector C is assembled more in the receptacle 33.
    [0009] When the lever 10 reaches the connecting position fm, as shown in FIG. 9, the connector C is correctly connected to the conjugate connector 30 and the connection lock part 17 of the lever 10 is locked on the housing 20 so that to regulate the rotation of the lever 10 to the initial position. In this way, the operation of connecting the connector C to the conjugate connector 30 is completed. The connector C of this embodiment has a lever 10 with a cam groove 11 for coupling the cam pin 34 to the conjugate connector 30. The lever 10 is rotatably mounted on the housing 20 and the initial latch L keeps the lever 10 in the initial position. However, the initial lock L is released to allow the rotation of the lever 10 when the connector C is partially connected to the conjugate connector 30. The lever 10 is then rotated from the initial position to the connecting position fm in order to connect the connector 'C correctly to the conjugate connector 30. The rotation control portions S are arranged on the lever 10 and the housing 20 separately from the initial lock L, and come into contact with each other in the direction of rotation of the lever 10 when the lever 3032833 - 10 - is at the end of connection position to regulate the rotation of the lever 10. In addition, the abutment portion 19 is close to the entrance of the groove 4, and abuts against the cam pin 34 if the housing 20 is pushed forward in the direction of connection to the conjugate connector 30 when the lever 10 is in the initial position. According to this configuration, the initial lock L is released when the connector C is temporarily connected to the conjugate connector 30. However, the stop portion 19 of the cam groove 11 abuts against the cam pin 34 to prevent the The housing 20 is further pushed toward the conjugate connector 30, and the rotation control portions S regulate the rotation of the lever 10 if the housing 20 is pushed in the connecting direction after the connector C has been temporarily connected to the conjugate connector 30. Thus, it is possible to prevent the operator from misinterpreting the fact that the operation of connecting the connector C to the conjugate connector 30 has been completed.
    [0010] In addition, the lever 10 rotates slightly upon release of the initial lock L. The rotation control portions S are separated when the initial lock L is activated and are brought into contact with each other after the rotation of the lever 10 accompanying the release of the initial lock L. Therefore, it is possible to prevent a rotation force of the lever 10 accompanying the release of the initial lock L acts on the rotation control portions S. In addition, the S rotation control portion on the side of the housing 20 is resiliently displaced due to an increase in contact force, thereby releasing a state in which the rotation of the lever 10 is regulated. Thus, the state in which the rotation of the lever 10 is regulated is released by an increase of a rotational force of the lever 10. This release operation and the operation of rotation of the lever 10 can be implemented under the form of a series of operations. The invention is not limited to the embodiment described and shown. For example, the following embodiments are also within the scope of the invention. Although several connectors C are connected to the conjugate connector 3032833 in the previous embodiment, there is no limitation thereto. For example, the invention can be applied to a connector assembly in which a conjugate connector and a connector are connected one by one. Conjugate connector 30 is a printed circuit connector in the previous embodiment. However, the invention can be applied in cases in which a conjugate connector is other than a printed circuit connector. The abutment portion 19 is arranged substantially at right angles to the longitudinal direction (connection direction) when the lever 10 is in the initial position in the previous embodiment. However, the inclination of the abutment portion is not a problem as long as the abutment portion can abut against the cam pin in the longitudinal direction. For example, the abutment portion may be slightly inclined such that the end of the rear side of the cam groove is farther forward than the inlet.
    [0011] In the previous embodiment, the part of the side wall of the housing 20 in which the housing-side regulating portion 27 is provided serves as an elastic displacement portion 28. However, that part of the side wall of the housing 20 in which the regulating portion of the housing side 27 is arranged which can not be moved elastically.
    [0012] Although the portion of the side wall of the housing 20 in which the housing-side regulating portion 27 is arranged serves as an elastic displacement portion 28 in the previous embodiment, a portion in which the control portion of the lever side is arranged can be moved elastically. The control portion of the lever side 18 is arranged on the outer peripheral surface of the cam plate 12 in the previous embodiment, but there is no limitation thereto. For example, the control portion of the lever side may be securely arranged on the upper or lower surface of the cam plate and the control portion of the housing side may be arranged on the upper or lower surface of the lever receiving portion.
    [0013] Although both the control portion of the lever side 18 and the control portion of the housing side 27 are projections in the previous embodiment, there is no limitation thereto. For example, one regulating portion may be a protrusion and the other regulating portion may be a cavity. The lever 10 turns slightly when the initial lock L is released in the previous embodiment. However, the lever may not rotate by accompanying the lock release. Although the respective rotation control portions S are separated when the initial lock L is activated and come into contact with each other after the rotation of the lever 10 accompanying the release of the initial lock L is completed in the previous mode. realization, there is no limitation to that.
