The connector 1 is disclosed in Patent Document 1 below, and includes a first connector housing 3, a second connector housing 4, an annular packing 5, and a front holder 6.

  The first connector housing 3 includes a terminal housing tube portion 9 that houses the female terminal 8 that is the first connection terminal, an outer tube portion 11 that defines a housing space 10 around the outer periphery of the terminal housing tube portion 9, and And a lock arm 13 having a locking portion 12 on the distal end side.

  The terminal accommodating cylinder portion 9 is formed with a terminal accommodating hole 9a for accommodating the female terminal 8 so as to penetrate forward from the rear end so that the female terminal 8 can be inserted from the rear end of the housing. The terminal accommodating cylinder portion 9 has a terminal locking lance 9b protruding into the terminal accommodating hole 9a. The terminal locking lance 9b engages with the female terminal 8 inserted into the terminal accommodating hole 9a up to the reference position to prevent the female terminal 8 from coming off.

  A housing space 10 on the outer periphery of the terminal housing tube portion 9 is a space for housing a fitting tube portion of the second connector housing 4 described later.

  The second connector housing 4 is inserted into the accommodating space 10 and is fitted on the outer periphery of the terminal accommodating cylinder portion 9 via the annular packing 5, and protrudes from the outer periphery of the fitting cylinder portion 17. And a terminal support portion 20 that supports a male terminal 19 as a second connection terminal to be fitted to the female terminal 8 on the inner side of the fitting cylinder portion 17.

  As shown in FIG. 8, the engagement protrusion 18 is formed on the engagement portion 12 at the distal end of the lock arm 13 at a fitting completion position where the fitting length of the terminal accommodating tube portion 9 to the fitting tube portion 17 reaches a specified length. By engaging, the fitting state of the first connector housing 3 and the second connector housing 4 is locked.

  The annular packing 5 is fitted and installed on the outer periphery of the base end side of the terminal accommodating cylinder portion 9, and when the fitting between the first connector housing 3 and the second connector housing 4 is completed, the terminal accommodating cylinder portion 9 and the fitting cylinder 17 are brought into close contact with each other, and the space between the terminal accommodating cylinder 9 and the fitting cylinder 17 is sealed (waterproof).

  The front holder 6 includes an insertion part 6 a that is inserted into the terminal accommodating cylinder part 9 and a tip wall 6 b that covers the front surface of the terminal accommodating cylinder part 9. The distal end wall 6 b is set to have an outer diameter larger than the outer diameter of the terminal accommodating cylinder portion 9, and prevents the annular packing 5 from coming off. The distal end wall 6b has a terminal guide hole 6c for guiding the male terminal 19 to the female terminal 8 side. A positioning wall 6d for positioning the front end portion of the female terminal 8 is integrally formed with the tip wall 6b.

  By the way, in such a connector 1, when a gap is generated in the fitting portion between the first connector housing 3 and the second connector housing 4 due to dimensional tolerance, assembly error, or the like, rattling occurs between the housings due to external vibration. . The backlash between the housings causes sliding friction of the terminal contact portion between the female terminal 8 and the male terminal 19 and accelerates wear of the terminal contact portion. As a result, there is a problem that the contact reliability is lowered.

Therefore, in the case of the connector 1, as shown in FIG. 7, a protruding portion (in the following Patent Document 1, a male side guidance restricting portion) is formed in a partial region in the circumferential direction of the base end side outer periphery of the fitting cylinder portion 17. 17a is formed. The raised portion 17a extends along the fitting direction between the connector housings. Furthermore, at a position corresponding to the raised portion 17a on the inner peripheral surface of the outer cylinder portion 11, there is a female-side raised portion (a female-side guidance regulating portion in Patent Document 1 below) 11a with which the raised portion 17a is slidably contacted. Is provided.
That is, in Patent Document 1, the bulging portion 17a and the female bulging portion 11a are brought into a tight-fitting state to eliminate play in the radial direction and prevent rattling due to external vibration or the like. .

JP 2005-174813 A

  However, since the connector 1 disclosed in Patent Document 1 is an interference fit between the fitting cylinder portion 17 and the outer cylinder portion 11, when the connector housings are fitted together, the female terminal 8 and the male terminal A large operating force is required not only for the fitting with 19 but also for the fitting between the fitting cylinder part 17 and the outer cylinder part 11, and there is a problem that the fitting operability is lowered.

Further, in the waterproof connector 1 disclosed in Patent Document 1, positioning of the connector housings in the mating direction when the mating is completed is performed by the engagement of the engagement protrusion 18 and the locking portion 12.
However, the engagement between the engagement protrusion 18 and the locking portion 12 can be positioned with high accuracy in the direction in which the fitting is disengaged, but does not leave any play in the direction in which the fitting is deepened. In other words, the backlash in the fitting direction cannot be completely eliminated. Moreover, since the amount of play in the mating completed state cannot be adjusted in a single way, there is a problem that it is not possible to regulate the amount of play between the connector housings depending on, for example, vibration conditions in the usage environment. there were.

  Accordingly, an object of the present invention is to solve the above-described problems, and to complete the fitting between the connector housings without increasing the fitting operation force, and the use environment of the connector is high vibration.

Therefore, the fitting state in which the lock arm is engaged with the second engagement portion is suitable when the connector is used in a high-vibration environment.

  That is, according to the configuration of (1) above, since the interference fitting structure is not employed as a means for preventing rattling, it is possible to complete the mating of the connector housings without increasing the mating operation force. . In addition, the engagement destination of the lock arm can be selected according to the vibration condition in the environment where the connector is used. When the environment where the connector is used is a high vibration environment, the lock arm is engaged with the second engagement portion. By using them together, the amount of backlash in the fitting direction between the connector housings can be reduced more than usual, and wear due to sliding of the terminal contact part due to external vibration etc. can be reduced. Improvement in fitting operability and improvement in contact reliability can be achieved at the same time.
