Definitions

  • the present invention relates to a connector having a bayonet structure to switch a locking state and an unlocking state between a pair of connectors with a weak operation force.
  • a connector having a bayonet structure to switch a locking state and an unlocking state between a pair of connectors with a weak operation force is conventionally known (refer to PTL 1).
  • a male connector 100 illustrated in Fig. 1 to Fig. 4 includes a male connector housing 110, and a bayonet ring (rotation member) 120 attached to the male connector housing 110 in a manner as to rotate between a locking start position and a locking end position of the connector.
  • the male connector housing 110 is provided with a plurality of terminal chambers 111 therein to accommodate male terminals (not illustrated).
  • the male connector housing 110 is provided, at a rear edge, with a first position regulation wall 112 and a second position regulation wall 113 each projecting outward.
  • a first lock wall surface 112a and a second lock wall surface 112b are each vertically formed on both sides of the first position regulation wall 112.
  • the bayonet ring 120 is provided with a plurality of cam projections 121 on the inner wall adjacent to a front edge of the bayonet ring 120.
  • the cam projections 121 can engage with cam grooves 202 provided on a female connector housing 201 of a mating female connector 200.
  • the bayonet ring 120 is provided, at the rear edge, with a locking arm 123 which can be deflected by a cantilever structure and provided with a lock claw 122, and an excessive rotation regulation projection 124.
  • the lock claw 122 has a locking surface 122a that sequentially comes into contact with the second position regulation wall 113 and the first position regulation wall 112 of the male connector housing 110 when the bayonet ring 120 is rotated in an unlocking direction.
  • the locking surface 122a is curved outward.
  • the second position regulation wall 113 locks the lock claw 122 as illustrated in Fig. 4(a). Once the bayonet ring 120 is rotated in the unlocking direction, the second position regulation wall 113 comes into contact with the locking surface 122a of the lock claw 122, thereby deflecting the locking arm 123 as illustrated in Fig. 4(b). The second position regulation wall 113 is then allowed to pass over the lock claw 122.
  • the male terminals are accommodated in the terminal chambers 111 of the male connector 100, and female terminals are accommodated in terminal chambers (not illustrated) of the mating female connector 200.
  • the male connector housing 110 is set in the locking start position with respect to the female connector housing 201 in a manner as to position the cam projections 121 at entrances of the cam grooves 202, followed by rotating the bayonet ring 120 from the locking start position to the locking end position (namely, in a locking direction).
  • the lock claw 122 then sequentially passes across the first position regulation wall 112 and the second position regulation wall 113 due to the deflection of the locking arm 123, so that the lock claw 122 moves to the locking end position.
  • the second position regulation wall 113 regulates the rotation of the lock claw 122 so as to hold the lock claw 122.
  • the male connector housing 110 and the female connector housing 201 move to the locking end position, and the cam projections 121 of the male connector housing 110 move along the cam grooves 202 of the female connector housing 201. Accordingly, the male connector 100 locks with the female connector 200, so that the male terminals are electrically connected to the female terminals.
  • the lock claw 122 sequentially passes across the second position regulation wall 113 and the first position regulation wall 112 due to the deflection of the locking arm 123, and thereby moves to the locking start position.
  • the male connector housing 110 and the female connector housing 201 shift to the locking start position.
  • the first position regulation wall 112 regulates the rotation of the lock claw 122 so as to hold the lock claw 122.
  • the connector according to the conventional example is desired to keep the bayonet ring 120 in the locking end position illustrated in Fig. 5 and Fig. 6 more stably because the connector is used under strong vibration condition and the like.
  • the male connector 100 of the conventional example is provided with the locking surface 122a curved outward, which comes into contact with the second position regulation wall 113. Since the lock claw 122 is biased by reaction force applied to the locking surface 122a from the second position regulation wall 113, the lock claw 122 easily moves in the unlocking direction. Further, as illustrated in Figs. 4(a) and 4(b), the inclined angle I of the locking surface 122a to the moving direction of the second position regulation wall 113 in the state where the locking arm 123 is not deflected, is approximately equal to the inclined angle J of the locking surface 122a in the state where the locking arm 123 is deflected. This also allows the lock claw 122 to easily move in the unlocking direction. This easy movement limits the ability to keep the bayonet ring 120 in the locking end position.
  • the increase of the inclined angle of the locking surface 122a may keep the bayonet ring 120 in the locking end position more stably. However, if the inclined angle of the locking surface 122a excessively increases; for example, if the inclined angle increases to a right angle, the possibility that the locking arm 123 is damaged increases.
  • the present invention has been made in view of the above-described problem. It is an object of the present invention to provide a connector capable of preventing damage to a locking arm provided in a rotation member and keeping the rotation member in a locking end position more stably.
  • a connector includes: a connector housing for accommodating one or more terminals; a rotation member attached to the connector housing in a manner as to be rotatable between a locking start position and a locking end position of the connector; a locking arm provided in the rotation member and including a lock claw having a locking surface, an unlocking direction side of the locking surface including a inclined surface linearly inclined to a base of the locking arm and a curved surface located at a top of the lock claw and formed in curved shape, the locking arm being deflectable; a first position regulation wall provided in the connector housing to lock the lock claw when the rotation member is located in the locking start position; and a second position regulation wall provided in the connector housing to lock the lock claw when the rotation member is located in the locking end position.
  • the lock claw In the state where the connector housing is set in the locking start position with respect to a mating connector housing, the lock claw passes across the first position regulation wall and the second position regulation wall due to a deflection of the locking arm and moves to the locking end position when the rotation member is rotated from the locking start position to the locking end position, so that the connector housing and the mating connector housing move to the locking end position in association with the movement of the lock claw.
  • the lock claw passes across the second position regulation wall and the first position regulation wall due to the deflection of the locking arm and moves to the locking start position when the rotation member is rotated from the locking end position to the locking start position, so that the connector housing and the mating connector housing move to the locking start position in association with the movement of the lock claw.
  • a locking wall surface of the first position regulation wall that comes into contact with the locking arm when the rotation member is rotated from the locking end position to the locking start position is preferably formed in a tapered shape.
  • the locking surface of the lock claw has the inclined surface that comes into contact with the second position regulation wall when the rotation member is rotated in the unlocking direction from the locking end position. Since the second position regulation wall presses the edge thereof into the locking surface, it is possible to keep the rotation member in the locking end position more stably without increasing a inclined angle of the locking surface. Further, due to the inclined surface provided in the locking surface, the inclined angle of the inclined surface changes to increasing with increasing of deflected level of the lock claw. This also contributes to keeping the rotation member in the locking end position more stably without increasing the inclined angle in the state in which the lock claw is not deflected.
  • the curved surface at the top of the locking surface of the lock claw allows the second position regulation wall to smoothly pass over the lock claw, which provides a sense of completion of engagement. Once the second position regulation wall passes over the lock claw, the second position regulation wall surely makes a sound when the deflection of the lock claw is released and the lock claw thus returns to the initial position, which provides an operator with a stable unlocking operability of the connector.
