Description

  The present invention relates to a connector.

  As a connector, there is known a connector that employs a so-called double-locking structure using a spacer in order to reliably prevent the terminal fitting from coming off (see, for example, Patent Document 1). As shown in FIG. 9, in this type of connector, a connector housing 501 includes a housing body 503 and a retainer (spacer) 505. The housing body 503 has a plurality of terminal accommodating chambers 509 that can accommodate terminal fittings 507 inserted from the rear end surface. Further, the housing body 503 has a hollow portion 511 that is recessed from the outer peripheral wall so as to intersect the length direction of the terminal accommodating chamber 509. The retainer 505 has a housing main body 503 at a temporary locking position that allows insertion of the terminal fitting 507 at a shallow insertion position with respect to the cavity portion 511 and a main locking position at which the terminal fitting 507 can be prevented from coming off at a deeper insertion position. Can be locked.

  In this connector, the terminal fitting 507 is inserted into the terminal accommodating chamber 509 with the retainer 505 in the temporary locking position. Thereafter, the retainer 505 is manually pushed into the main locking position, the flexible arm 513 is bent, and the main locking claw (not shown) gets over the main locking projection (not shown) to be in the final locking state. As a result, the secondary locking projection 515 of the retainer 505 becomes the secondary locking that is locked to the stepped portion of the terminal fitting 507.

  Further, in the connector disclosed in Patent Document 2, as shown in FIG. 10, a housing 517 is formed with a terminal accommodating chamber 521 for inserting a terminal fitting 519, and crosses the terminal accommodating chamber 521. The retainer 523 is incorporated. The retainer 523 is incorporated so as to be displaceable between an open position where the terminal accommodating chamber 521 is fully opened to allow the insertion of the terminal fitting 519 and a locking position which protrudes into the terminal accommodating chamber 521 and engages with the terminal fitting 519. . A spring 525 is disposed inside the housing 517, and the spring 525 biases the retainer 523 to the locking position. Furthermore, a guide surface 527 is formed on the retainer 523, and when the terminal fitting 519 is inserted, the retainer 523 is displaced from the locking position to the open position, and the terminal accommodating chamber 521 is automatically opened.

  In this connector, since the retainer 523 is biased to the locking position by the spring 525 prior to inserting the terminal fitting 519 into the terminal receiving chamber 521, the locking portion of the retainer 523 has entered the terminal receiving chamber 521. It has become. When the terminal fitting 519 is inserted into the terminal accommodating chamber 521 in this state, the terminal fitting 519 comes into sliding contact with the guide surface 527 of the retainer 523, and the entire retainer is displaced against the spring 525 to the open position. As a result, the terminal accommodating chamber 521 is opened. When the terminal fitting 519 is inserted to the proper position, the retainer 523 returns to the locking position, engages with the terminal fitting 519, and is prevented from coming off.

However, the conventional connector housing 501 shown in FIG. 9 requires a step of returning the retainer 505 to the temporary locking position of the housing body 503 using a jig when releasing the retainer 505 to the temporary locking position. For this reason, the maintenance work takes time.
On the other hand, the conventional connector shown in FIG. 10 can displace the retainer 523 to the open position without using a jig by pressing the operation piece 529. On the other hand, a spring 525 which is a separate member for biasing the retainer 523 to the locking position is required. For this reason, there is a problem that the number of parts increases and the assembly of the connector becomes complicated, and the size of the connector increases.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a connector that can move a spacer to a temporary locking position without using a jig and without incorporating a separate member. is there.

The above object of the present invention is achieved by the following configuration.
(1) A housing in which a terminal accommodating chamber for accommodating a terminal is formed, a temporary locking position that is incorporated in the housing and allows the terminal to be inserted into and removed from the terminal accommodating chamber, and prevents the terminal from coming off. A connector provided with a spacer that is locked to the housing at the main locking position, and a lock arm that is provided on the outer surface of the housing and locks the mating connector in a fitted state, wherein the lock arm is locked A connector that engages with the spacer and moves the spacer to a temporary locking position when the spacer is displaced by a predetermined amount or more in the releasing direction.

  According to the connector having the configuration (1), the terminal is inserted into the terminal accommodating chamber in a state where the spacer is attached to the housing at the temporary locking position. When the spacer is moved to the final locking position, the spacer comes into contact with the terminal and the terminal is prevented from coming off. When the connector fitted with the mating connector is released from the mating lock with the mating connector, the lock arm is released from being locked by pressing the operation portion of the lock arm. When the lock arm is further pressed in the unlocking direction, the lock arm engages with the spacer and moves the spacer from the main locking position to the temporary locking position. By moving the spacer to the temporary locking position, the terminal can be extracted from the terminal accommodating chamber.

(2) In the connector having the configuration of (1), the spacer is inserted in a direction orthogonal to the insertion / removal direction of the terminal with respect to the terminal accommodating chamber, and is attached to the outer surface of the housing at the final locking position. A protruding tip portion engages with the lock arm.

  According to the connector having the configuration (2), the spacer is inserted into the housing in a direction perpendicular to the insertion / removal direction of the terminal to / from the housing. The lock arm approaches the outer surface of the housing when the lock arm is unlocked with respect to the mating connector. The front end of the spacer protruding in the pushing direction from the outer surface of the housing is disposed on the outer surface of the housing corresponding to the lock arm. Accordingly, when the lock arm is further pushed in, the lock arm displaced by a predetermined amount or more in the unlocking direction pushes the tip of the spacer into the housing. The spacer pushed into the lock arm is moved from the main locking position to the temporary locking position. Thus, the unlocking force acts efficiently because the unlocking direction of the lock arm coincides with the moving direction of the spacer to the temporary locking position. As a result, the pressing force when returning the spacer to the temporary locking position can be reduced.

  According to the connector of the present invention, the spacer can be moved to the temporary locking position without using a jig and without incorporating another member.

  On both sides of the male spacer 29 and the female spacer 19, locking side plates 93 are arranged to face each other. A locking claw 95 shown in FIG. 4 protrudes from the upper end of the inner facing surface of the locking side plate 93. When the male spacer 29 and the female spacer 19 are inserted into the male spacer insertion port 63 and the female spacer insertion port 79, respectively, the locking claw 95 rides on the guide inclined surface 87 of the first locking receiving portion 83, and thereafter, FIG. ) And (b), it is latched by the temporary latching vertical surface 89 and is disposed between the first latching receiving part 83 and the second latching receiving part 85. This state is a temporary locking position of the male spacer 29 and the female spacer 19. In this temporary locking position, as shown in FIGS. 2 and 3, the secondary locking portion 43 has not entered the male terminal accommodating chamber 59 and the female terminal accommodating chamber 75. When the male spacer 29 and the female spacer 19 are further inserted, the locking claw 95 climbs over the guide inclined surface 87 of the second locking receiving portion 85 and then reaches the main locking inclined surface 91 shown in FIGS. 5 (a) and 5 (b). Locked. This state is the final locking position of the male spacer 29 and the female spacer 19.

The male spacer 29 and the female spacer 19 are provided with the secondary locking portion 43 that can be disposed below the male terminal accommodating chamber 59 and the female terminal accommodating chamber 75. When the male spacer 29 and the female spacer 19 reach the final locking position shown in FIG. 5, the secondary locking portion 43 hits the spacer contact portion 35 of the male terminal 21 and the female terminal 11 as shown in FIG. 21 and the female terminal 11 are prevented from coming out backward.
As described above, the male spacer 29 and the female spacer 19 are incorporated into the male housing 25 and the female housing 15, and are temporarily locked to allow the terminals to be inserted into the male terminal accommodating chamber 59 and the female terminal accommodating chamber 75 (see FIG. 4). And the main locking position (see FIG. 5) for preventing terminal removal.

  Here, in particular, the female spacer 19 is inserted in a direction orthogonal to the insertion / removal direction of the female terminal 11 to / from the female terminal accommodating chamber 75. In the present embodiment, the male spacer 29 is the same. In the female spacer 19, a protrusion 97, which is a distal end portion in the pushing direction that protrudes from the outer surface 71 of the female housing 15 in the final locking position, engages with the lock arm 69 (see FIG. 6B). The lock arm 69 is provided with a pressing portion 99 on the opposite side of the lock claw 73 (that is, the side facing the outer surface 71). The pressing portion 99 approaches the outer surface 71 when the lock arm 69 is operated in the unlocking direction. The protruding portion 97 of the female spacer 19 protruding from the outer surface 71 is disposed on the outer surface 71 of the female housing 15 corresponding to the pressing portion 99. When the lock arm 69 is displaced by a predetermined amount or more in the unlocking direction, the pressing portion 99 is engaged with the protrusion 97 of the female spacer 19 to move the female spacer 19 to the temporary locking position.

Next, the operation of the connector having the above configuration will be described.
The female connector 13 according to this embodiment includes a female spacer 19 in the female housing 15. As shown in FIGS. 3A and 4A, the female spacer 19 is attached to the female housing 15 in the temporary locking position before the female terminal 11 is inserted into the female terminal accommodating chamber 75. Similarly, as shown in FIG. 3B and FIG. 4B, the male spacer 29 is attached to the male connector 23 at the temporary locking position.

  The female spacer 19 at the temporary locking position allows the female terminal 11 to be inserted into the female terminal accommodating chamber 75. When the female terminal 11 is inserted into the female terminal receiving chamber 75 in this state, the female terminal 11 is brought into a primary locking state in which the female terminal 11 is locked by the lance 41 provided in the female terminal receiving chamber 75, and the rear omission is restricted. Is done. Further, when the female spacer 19 is moved to the main locking position, the secondary locking portion 43 of the female spacer 19 comes into contact with the spacer contact portion 35 of the female terminal 11 to prevent the female terminal 11 from coming back backward. As a result, the female terminal 11 is brought into a secondary locking state as shown in FIG. Similarly, as shown in FIG. 6A, the male terminal 21 is also in the secondary locking state for the male connector 23.

As shown in FIG. 7A, the female connector 13 is fitted with the male connector 23 in a state where the female terminal 11 (see FIG. 6) is secondarily locked. When the female connector 13 and the male connector 23 are fitted, the lock claw 73 of the lock arm 69 is engaged with the lock receiving portion 57 of the male connector 23 as shown in FIG. The male connector 23 is locked in the fitted state.
When the lock arm 69 gets over the lock receiving portion 57, it moves closer to the outer surface 71. The displacement in the unlocking direction of the lock arm 69 when the connector is fitted is less than a predetermined value (less than a predetermined displacement d) as shown in FIG. 7C, so that the female spacer 19 is moved to the temporary locking position. There is no.

  When the female terminal 11 needs to be replaced or the like, the female connector 13 is pressed by the operation portion 74 of the lock arm 69 and the fitting lock with the male connector 23 is released. That is, as shown in FIG. 8A, the free end of the lock arm 69 is pressed and the lock claw 73 of the lock arm 69 is disengaged from the lock receiving portion 57 of the male connector 23. Release is performed. At this time, in the direction in which the lock pawl 73 is disengaged, a protrusion 97 in the pushing direction of the female spacer 19 pushed into the final locking position is disposed so as to protrude from the outer surface 71 of the female housing 15.

  When the lock arm 69 is further pressed in the unlocking direction, as shown in FIG. 8B, the pressing portion 99 provided on the lock arm 69 engages the female spacer 19 and presses the projection 97. The female spacer 19 whose protrusion 97 is pressed by the pressing portion 99 is moved from the main locking position to the temporary locking position. That is, the female spacer 19 is moved to the temporary locking position simultaneously with the unlocking of the female connector 13. Thereby, the female spacer 19 can be moved to the temporary locking position without using a jig only by displacing the lock arm 69 by a predetermined amount or more in the unlocking direction. In the lock arm 69 that has moved the female spacer 19 to the temporary locking position, the pressing portion 99 abuts against the outer surface 71 and further pressing is restricted. That is, the outer surface 71 is a surface for preventing excessive displacement of the lock arm 69.

  Further, in the female connector 13 of the present embodiment, the female spacer 19 is pushed into and inserted into the female housing 15 in a direction orthogonal to the insertion / removal direction of the female terminal 11 with respect to the female housing 15. In the female spacer 19 inserted into the female housing 15, a protrusion 97 in the pushing direction protrudes from the outer surface 71 of the female housing 15.

  On the other hand, a cantilevered elastic arm-like lock arm 69 is provided on the outer surface 71 of the female housing 15. The lock arm 69 has a lock claw 73 protruding from the side opposite to the side facing the outer surface 71 of the female housing 15, and this lock claw 73 engages with the lock receiving portion 57 of the male connector 23. That is, when the lock arm 69 is pushed toward the outer surface 71 in the approaching direction, the lock claw 73 is separated from the lock receiving portion 57 and unlocked.

  The pressing portion 99 of the lock arm 69 approaches the outer surface 71 of the female housing 15 when the lock arm 69 is unlocked with respect to the male connector 23. The protrusion 97 of the female spacer 19 protruding from the outer surface 71 of the female housing 15 is disposed on the outer surface 71 of the female housing 15 corresponding to the pressing portion 99 of the lock arm 69.

  Accordingly, when the lock arm 69 from which the lock pawl 73 is released from the lock receiving portion 57 is further pushed, the pressing portion 99 of the lock arm 69 displaced by a predetermined amount or more in the unlocking direction becomes the projection 97 of the female spacer 19. Will be pushed into the female housing 15. Thus, the unlocking force acts efficiently because the unlocking direction of the lock arm 69 and the moving direction of the female spacer 19 to the temporary locking position coincide. As a result, the pressing force when returning the female spacer 19 to the temporary locking position can be reduced.

  In the above-described embodiment, the configuration in which the lock arm 69 is provided on the female connector 13 that accommodates the female terminal 11 has been described. However, the connector according to the present invention is a male connector that accommodates the male terminal 21 on the contrary. The structure provided with a lock arm may be sufficient. In this case, the lock arm is displaced in the unlocking direction by a predetermined amount or more to engage with the male spacer and move the male spacer to the temporary locking position.

Therefore, according to the female connector 13 according to the present embodiment, the female spacer 19 can be moved to the temporary locking position without using a jig and without incorporating another member.
In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
