[Technical field]

[0001] The present invention relates to a lever-type connector. [Background technology]

[0002] As an example of a connector having a pair of connector housings that are fitted together, there is a lever-type connector in which a rotatable lever is provided on one of the connector housings, and the rotation of this lever applies a mating force and a disengagement force to the connector housings (see, for example, Patent Documents 1 and 2).

[0003] Some of these lever-type connectors are equipped with a Connector Position Assurance (CPA) member that detects and ensures proper mating of the connector housings. The connector position assurance member is attached to a side surface of the housing on which the lever is provided, and is movable between a partial locking position in which the lever is unlocked and a full locking position in which the lever is locked. When the connector housings have been mated, i.e., when the lever holds the connector housings in the mated state, the connector position assurance member can be moved from the partial locking position to the full locking position (mating assurance position).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a schematic perspective view showing a lever-type connector 1 according to one embodiment of the present invention and a mating connector housing 10. Figs. 2 to 4 are a schematic perspective view, an exploded perspective view, and a side view of the lever-type connector 1 according to this embodiment.

[0012] As shown in FIGS. 1 to 4, a lever-type connector 1 according to this embodiment includes a connector housing 20 that is fitted to and separated from a mating connector housing 10, and a lever 30. As shown in FIG. The lever 30 is provided rotatably relative to the connector housing 20, and by rotating this lever 30, a mating force and a disengagement force are applied between the connector housing 20 and the mating connector housing 10. By rotating this lever 30, the connector housing 20 moves relative to the mating connector housing 10 along the insertion / removal direction A, and they are mated and disengaged with each other.

[0013] This lever-type connector 1 is used as a so-called service plug that cuts off the flow of electricity between a power supply unit and a load in order to ensure the safety of work during maintenance of the electrical system in vehicles such as electric vehicles and hybrid cars. Specifically, by fitting the connector housing 20 into the mating connector housing 10, electricity can be passed between the power supply unit and the load, and by removing the connector housing 20 from the mating connector housing 10, the flow of electricity between the power supply unit and the load is cut off.

[0014] As shown in Fig. 1, the mating connector housing 10 is molded from an electrically insulating synthetic resin. The mating connector housing 10 has a flange portion 10a that protrudes to the outer periphery, and is attached to a power supply device or the like by fixing this flange portion 10a to a case. In addition, at one end side of the mating connector housing 10, a storage portion 19 is formed in the flange portion 10a.

[0015] The mating connector housing 10 has a tubular receiving portion 12 with an open top. The tubular receiving portion 12 is formed in an elliptical shape when viewed from above. Side walls 11 are provided on both sides of the tubular receiving portion 12 of the mating connector housing 10, and fulcrum projections 11a are formed on the side walls 11 near the middle of the mating connector housing 10.

[0016] The mating connector housing 10 is provided with a pair of tab terminals (not shown) made of a bus bar that is L-shaped in side view and made of a conductive metal material inside the accommodating tube portion 12. Each tab terminal is disposed on either side of an insulating plate portion 17 that is a part of the mating connector housing 10. A power line from a power supply unit and a power line to a load are connected to each tab terminal.

[0017] The connector housing 20 is molded from an electrically insulating synthetic resin, and has an outer circumferential cylindrical portion 21 and an inner circumferential cylindrical portion 22 inside the outer circumferential cylindrical portion 21 (see FIG. 14). The outer circumferential cylindrical portion 21 is formed in a bottomed cylindrical shape that is open downward, and has a pair of support shafts 23 protruding from both side surfaces. Furthermore, a pair of locking projections 26 protruding near the support shafts 23.

[0018] Furthermore, a pair of main lock claws 28 serving as housing locking portions are formed near one end on both side surfaces of the outer circumferential cylindrical portion 21. These main lock claws 28 protrude from the side portion of the connector housing 20 toward one end. Furthermore, a pair of sub-lock claws 29 are formed at one end of the outer circumferential cylindrical portion 21.

[0019] The inner cylindrical portion 22 of the connector housing 20 is formed in an elliptical shape in a plan view that is slightly smaller than the outer shape of the accommodating cylindrical portion 12 of the mating connector housing 10. The connector housing 20 is placed over the accommodating cylindrical portion 12 of the mating connector housing 10 so that the inner cylindrical portion 22 fits into the accommodating cylindrical portion 12 of the mating connector housing 10. By fitting the inner cylindrical portion 22 into the accommodating cylindrical portion 12, the accommodating cylindrical portion 12 fits between the inner cylindrical portion 22 and the outer cylindrical portion 21.

[0020] In the connector housing 20, an annular seal member 45 is fitted between the outer circumferential cylindrical portion 21 and the inner circumferential cylindrical portion 22 and fixed by the lower housing 25 (see FIG. 14). The seal member 45 comes into close contact with the inner circumferential surface of the accommodating cylindrical portion 12 when the mating connector housing 10 and the connector housing 20 are fitted together, and seals off water between the accommodating cylindrical portion 12 and the inner circumferential cylindrical portion 22.

[0021] The connector housing 20 is provided therein with five clip-shaped terminals 40 made of a conductive metal material and having a clip shape. The clip-shaped terminals 40 are configured to clamp a pair of tab terminals of a mating connector housing, thereby electrically connecting the pair of tab terminals to each other. These clip-shaped terminals 40 accommodated in the connector housing 20 are fixed by a lower housing 25 fitted into the inner cylindrical portion 22.

[0022] The lever 30 is molded from a synthetic resin and has a pair of arm portions 31 and a connecting portion 32. One end of the arm portion 31 is connected by the connecting portion 32 to form a rotation end, and the other end has a bearing hole 34 that serves as the rotation center. A pair of support shafts 23 of the connector housing 20 are inserted into the bearing hole 34 of the arm portion 31, whereby the lever 30 is supported rotatably relative to the connector housing 20. The other end of the pair of arm portions 31 of the lever 30 forms a pressing portion 36 having a curved surface 35.

[0023] Furthermore, a pair of arm portions 31 of the lever 30 are each formed with an escape groove 33 in the vicinity of one end side of the bearing hole 34. The locking projections 26 protruding from both side surfaces of the outer circumferential cylindrical portion 21 of the connector housing 20 are inserted into the escape grooves 33.

[0024] The lever 30 rotates between a first operating position (see FIG. 6) and a second operating position (see FIG. 8). When the lever 30 is rotated from the first operating position to the second operating position, a mating force in the mating direction is applied between the mating connector housing 10 and the connector housing 20, and when the lever 30 is rotated from the second operating position to the first operating position, a removal force in the removal direction is applied.

[0025] Main lock holes 38 serving as lever locking portions are formed on the inner side of the arm portion 31 of the lever 30, in the vicinity of the connecting portion 32. These main lock holes 38 are engaged with main lock claws 28 formed on the outer circumferential cylindrical portion 21 of the connector housing 20. The main lock claws 28 and the main lock holes 38 constitute a locking portion 50.

[0026] When the locking portion 50 is slid in a direction in which the main locking claw 28 is inserted into the main locking hole 38 with the lever 30 placed in the second operating position, the locking portion 50 locks the lever 30 with respect to the connector housing 20 and restricts the rotation of the lever 30. This causes the lever-type connector 1 to be locked with the connector housing 20 fitted to the mating connector housing 10.

[0027] A sub-lock plate portion 39 is provided on the connecting portion 32 of the lever 30. A pair of sub-lock locking portions 39a are formed on this sub-lock plate portion 39 (see FIG. 14). The pair of sub-lock locking portions 39a are locked by a pair of sub-lock claws 29 provided on the outer peripheral cylindrical portion 21 of the connector housing 20 when the lever 30 is rotated from the second operating position to the first operating position. This temporarily restricts the rotation of the lever 30 when the lever 30 is rotated from the second operating position to the first operating position.

[0028] This prevents sparks from occurring between the tab terminal (not shown) and the clip-like terminal 40 due to abrupt separation of the mating connector housing 10 and the connector housing 20. When the sub-lock engaging portion 39a of the lever 30 is engaged with the sub-lock claw 29, the operating portion 37 is pressed with a finger to elastically deform the sub-lock plate portion 39, whereby the sub-lock engaging portion 39a is released from the sub-lock claw 29 and the lever 30 can be rotated to the first operating position.

[0029] 5(a) to 5(c), a locking piece 52 is provided on the end of a cylindrical support shaft 23 formed in the connector housing 20, protruding laterally. In addition, an outer circumferential surface 56 of this support shaft 23 is provided with a fitting portion 55 having a two-face width formed by a pair of cutout recesses 53 aligned in the circumferential direction and extending radially outward from the axis. The fitting portion 55 is formed on the inner surface side of the locking piece 52, and has a circumferential width W1 that is narrower than a circumferential width W2 of the locking piece 52.

[0030] 4, a bearing hole 34 formed in the arm portion 31 of the lever 30 has an insertion recess 62 formed in a part of its inner circumferential surface. The locking piece 52 of the support shaft 23 can be inserted into this insertion recess 62. Furthermore, a recess 65 having parallel side walls into which the fitting portion 55 of the support shaft 23 can be inserted is formed in the inner circumferential surface of the bearing hole 34. The insertion recess 62 and the recess 65 are formed at different circumferential positions on the inner circumferential surface of the bearing hole 34.

[0031] The lever 30 is attached to the connector housing 20 by passing the locking piece 52 of the support shaft 23 through the insertion recess 62 of the bearing hole 34. When the lever 30 attached to the connector housing 20 is rotated, the opening edge of the bearing hole 34 is locked with the locking piece 52. This prevents the support shaft 23 from coming out of the bearing hole 34, and maintains the lever 30 attached to the connector housing 20.

[0032] Next, a procedure for fitting the connector housing 20 into the mating connector housing 10 in the lever-type connector 1 having the above configuration will be described. In the lever-type connector 1 configured as above, to fit the connector housing 20 into the mating connector housing 10, the connector housing 20 with the lever 30 disposed in the first operating position is brought close to the mating connector housing 10 as shown in Figures 6 and 7. When the lever 30 is disposed in the first operating position, the locking projections 26 protruding from both sides of the outer circumferential cylindrical portion 21 lock the widthwise sides of the arm portion 31, thereby restricting undesired rotation.

[0033] The lever-type connector 1 is then placed in a detachable state in which the inner circumferential cylindrical portion 22 of the connector housing 20 is fitted into the accommodating cylindrical portion 12 of the mating connector housing 10 . In this attachment / detachment operation state, the lever 30 in the first operation position is rotated toward the second operation position shown in Figures 8 and 9. Then, the locking projections 26 protruding from both side surfaces of the outer circumferential tube portion 21 are inserted into the escape grooves 33 of the arm portion 31. Here, the lever 30 can rotate and slide smoothly without interfering with the locking projections 26.

[0034] When the lever 30 is rotated toward the second operating position, the curved surface 35 of the pressing portion 36 of the lever 30 abuts and slides against the fulcrum protrusion 11a formed on the side wall portion 11 of the mating connector housing 10. This applies a mating force between the mating connector housing 10 and the connector housing 20, and the connector housing 20 is pulled into and mated with the mating connector housing 10.

[0035] The upper end of the accommodating cylindrical portion 12 of the mating connector housing 10 is brought into close contact with a seal member 45 provided on the inner cylindrical portion 22 of the connector housing 20, thereby sealing off the gap between the mating connector housing 10 and the connector housing 20. In the engaged state in which the lever 30 is positioned at the second operating position, a pair of tab terminals (not shown) are clamped by the clip-shaped terminal 40, and the power lines connected to the pair of tab terminals are electrically connected to each other via the clip-shaped terminal 40.

[0036] In the mated state of the lever-type connector 1 with the lever 30 in the second operating position, as shown in Fig. 10, in the locking portion 50, the main lock hole 38 of the lever 30 is disengaged from the main lock claw 28 formed on the outer circumferential cylindrical portion 21 of the connector housing 20. Thus, when the lever 30 is disposed in the second operating position, it is not locked and the rotation of the lever 30 is not restricted.

[0037] 11 and 12, the lever 30 located in the second operating position is slid in a direction (leftward in FIG. 12) in which the fitting portion 55 of the support shaft 23 is fitted into the recess 65 of the bearing hole 34. Then, as shown in FIG. 13, the lever 30 with the main lock claw 28 of the connector housing 20 inserted into the main lock hole 38 of the lever 30 is locked against rotation by the lock portion 50.

[0038] That is, in the mated state of the lever-type connector 1 with the lever 30 in the second operating position, the lever 30 is slid to the locking position of the locking portion 50, whereby the lever 30 is locked in the second operating position and the rotation of the lever 30 is restricted. In this manner, the locking portion 50 locks the lever 30 and restricts its rotation, thereby maintaining the mating connector housing 10 and the connector housing 20 in a properly mated state in which they are completely mated.

[0039] Here, the lever 30 can slide in the direction of fitting the fitting portion 55 into the recess 65 only when the center line of the recess 65 in the bearing hole 34 coincides with the center line of the fitting portion 55 of the support shaft 23 (the properly fitted state of the lever-type connector 1 with the lever 30 in the second operating position).

[0040] That is, the lever-type connector 1 of this embodiment has a connector position assurance function in which the rotation of the lever 30 is locked by the locking portion 50 only when the connector housing 20 is in a properly mated state where it is completely mated with the mating connector housing 10.

[0041] To remove the connector housing 20 from the mating connector housing 10, the lever 30 is slid in a direction (rightward in FIG. 9) in which the fitting portion 55 of the support shaft 23 is pulled out of the recess 65 of the bearing hole 34. Then, as shown in FIG. 10, the main lock hole 38 of the lever 30 is disengaged from the main lock claw 28 of the connector housing 20, the locking of the lever 30 by the locking portion 50 is released, and the lever 30 becomes rotatable.

[0042] The lever 30, which is now rotatable, is rotated toward the first operating position. Then, as the lever 30 rotates, the pressing portion 36 of the lever 30 comes into contact with and slides against the bottom surface of the accommodating portion 19 of the mating connector housing 10. This applies a separation force between the mating connector housing 10 and the connector housing 20.

[0043] When the lever 30 is rotated to the first operating position, the sub-lock claw 29 engages the sub-lock engaging portion 39a, temporarily restricting the rotation of the lever 30. This prevents sparks from occurring between the tab terminal and the clip-shaped terminal 40 due to the sudden separation of the mating connector housing 10 and the connector housing 20.

[0044] Thereafter, the operating portion 37 of the sublock plate portion 39 is pressed with a finger to release the sublock engaging portion 39a from the sublock claw 29, and the lever 30 is rotated to the first operating position to separate the connector housing 20 from the mating connector housing 10. Then, the inner circumferential cylindrical portion 22 of the connector housing 10 is pulled out of the accommodating cylindrical portion 12 of the mating connector housing 10, the clip-like terminals 40 are pulled out of the pair of tab terminals, and the electrical connection between the power lines is released.

[0045] As described above, in the lever-type connector 1 according to this embodiment, the fitting portion 55 is provided on the outer circumferential surface 56 of the support shaft 23 in the connector housing 20, and the inner circumferential surface of the bearing hole 34 in the lever 30 is provided with a recess 65 into which the fitting portion 55 can fit. Then, the lever 30, which is located in the second operating position, is slid in a direction in which the fitting portion 55 fits into the recess 65, so that a locking portion 50 is provided between the connector housing 20 and the lever 30 to lock the rotation of the lever 30. With this configuration, a connector position assurance function is provided that can detect proper mating of the mating connector housing 10 and the connector housing 20.

[0046] In other words, by simply sliding the lever 30 rotated to the second operating position in the direction in which the fitting portion 55 of the support shaft 23 fits into the recess 65 of the bearing hole 34, it is possible to detect proper fitting between the mating connector housing 10 and the connector housing 20 and ensure the connector position. Furthermore, the lever-type connector 1 of this embodiment can reduce the number of parts and be made smaller than a conventional lever-type connector in which a connector position assurance member is attached to the side surface of the housing on which the lever is provided.

[0047] Furthermore, according to the lever-type connector 1 of this embodiment, the locking portion 50 has the main locking claw 28 provided on the connector housing 20, and the main locking hole 38 provided on the lever 30 so as to be locked by the main locking claw 28 when the fitting portion 55 is fitted into the recess 65. Therefore, the locking portion 50 can be configured in a small size and with a simple shape.

[0048] Furthermore, according to the lever-type connector 1 of this embodiment, the locking piece 52 is provided at the end of the support shaft 23, and a part of the inner peripheral surface of the bearing hole 34 is provided with an insertion recess 62 through which the locking piece 52 can be inserted. The circumferential width W1 of the fitting portion 55 formed on the inner surface side of the locking piece 52 is narrower than the circumferential width W2 of the locking piece 52. Thus, the support shaft 23 can be configured compactly by a simple shape in which the locking piece 52 and the fitting portion 55 are combined together.

[0049] Therefore, according to the lever-type connector 1 of this embodiment, while providing a connector position assurance function, it is possible to reduce the number of parts, thereby enabling cost reduction and size reduction.

[0050] The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, etc. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.
