  • the locking convex portion 83 does not protrude into the cavity 44. Therefore, when the terminal 10 is inserted into the cavity 44 through the rear opening 45, it can be inserted into the back of the cavity 44, that is, to the front side, without being caught by the locking protrusion 83.
  • the elastic piece 87 of the lance 86 is disposed within the temporary attachment opening 38.
  • the temporary locking protrusion 88 protruding from the elastic piece 87 protrudes from the temporary attachment opening 38 into the cavity 44. Therefore, when the terminal 10 is inserted into the cavity 44 through the rear opening 45, the terminal connection portion 13 of the terminal 10 comes into contact with the temporary locking protrusion 88.
  • the tip of the terminal connection portion 13 comes into contact with the first guide surface 88f1 of the temporary locking convex portion 88 (see FIG. 7).
  • the first guide surface 88f1 is a surface that gradually reduces the protruding dimension of the temporary locking convex portion 88 as the terminal 10 is inserted toward the rear side. Therefore, when the terminal 10 is inserted deep into the cavity 44, the tip of the terminal connecting portion 13 comes into contact with the first guide surface 88f1, and the temporary locking convex portion 88 is moved in the direction of retreating from the cavity 44, that is, on the right side. Or push it out to the left. Thereby, the terminal 10 can be moved to the back of the cavity 44, that is, to the front side.
  • the temporary locking convex portion 88 When the terminal connecting portion 13 passes over the temporary locking convex portion 88, the temporary locking convex portion 88 returns to the state of protruding into the cavity 44 due to the elastic force of the elastic piece 87 to return to its original shape. As a result, the temporary locking convex portion 88 becomes temporarily locked in the recess 14 of the terminal 10 (see FIG. 6).
  • the terminal 10 is inserted into each cavity 44 in the same manner as above. With each terminal 10 inserted into each cavity 44, the temporary locking convex portion 88 temporarily locks the terminal 10. Therefore, once the terminal 10 is inserted into the cavity 44, the insertion work of the terminal 10 can be easily carried out one after another without worrying about the terminal 10 coming off later.
  • the retainer 80 is pushed from the temporary mounting position to the final mounting position.
  • the temporary locking convex portion 88 is pushed downward in the direction in which the retainer 80 is pushed, that is, perpendicular to the direction in which the cavity 44 extends. Then, the temporary locking convex portion 88 moves from the recess 14 toward the core wire crimping portion 12 and comes into contact with the core wire crimping portion 12 .
  • the second guide surface 88f2 is a surface that gradually reduces the protrusion dimension of the temporary locking convex portion 88 toward the distal end side of the lance 86.
  • the second guide surface 88f2 comes into contact with the core wire crimping part 12, and the temporary locking convex part 88 moves in the direction of retreating from the cavity 44, that is, to the outer right side or the outer left side.
  • the temporary locking convex portion 88 moves beyond the core wire crimping portion 12 and below the core wire crimping portion 12, and the temporary locking with respect to the terminal 10 is released.
  • the temporary locking convex portion 88 that has exceeded the core wire crimping portion 12 downward returns to its original position on the side of the cavity 44 by the elastic force of the elastic piece 87, and is disposed in the partial recess 44h of the cavity 44.
  • the locking protrusion 83 enters into the cavity 44 through the main mounting opening 36.
  • the locking convex portion 83 enters into the recess 14 from the side opposite to the core wire crimping portion 12.
  • the retainer 80 includes the lances 86 that can be temporarily engaged with the terminals 10 in the temporary attachment position, and the locking protrusions that can be engaged with the terminals 10 in the final attachment position. This makes it possible to simplify the shape of the housing 30, and to reduce the size of the connector 20.
  • the shape of the housing tends to be more complicated. Furthermore, since the housing often includes a guide structure, a lock structure, etc. for connection to a mating connector, the shape of the housing tends to become complicated from this point of view as well. For this reason, forming a lance in the housing tends to increase the size due to mold restrictions.
  • the lance 86 on the retainer 80 as in this embodiment, it becomes possible to simplify the shape of the housing 30 and make it smaller. Further, since the retainer 80 has a simpler shape than the housing 30, even if the housing 30 is formed on the retainer 80, there are few mold restrictions, and the retainer 80 is less likely to become large. Therefore, the shape of the connector 20 as a whole can be simplified and the size can be reduced.
  • both the lance 86 and the locking protrusion 83 can be locked in the recess 14 of the terminal 10. Therefore, there is no need to separately form a portion on the terminal 10 where the lance 86 temporarily locks. This makes it possible to simplify and downsize the terminal 10, which contributes to downsizing the connector 20.
  • the lance and the locking protrusion may lock at different locations with respect to the terminal.
  • the lance 86 is formed to protrude in the same direction as the locking wall portion 84 in the middle of the retainer body 82 in the extending direction so that it can be placed in the temporary attachment opening 38 . elastically deforms along the direction that intersects with the For this reason, the configuration for forming the lance 86 can be made smaller compared to the case where the lance is placed along the extending direction of the cavity. This makes it possible to reduce the size of the connector 20 in the front-rear direction.
  • the lance may be along the extending direction of the cavity.
  • the lance may protrude from the locking wall along the extending direction of the cavity, and an opening may be formed in the side of the housing in which the lance can be placed.
  • the base end of the lance 86 is integrally connected to the locking convex portion 83. Therefore, the lance 86 is reinforced and is less likely to be damaged.
  • the lance 86 has an elastic piece 87 and a temporary locking convex portion 88, and when the retainer 80 is located at the temporary installation position, the lance 86 is placed in the temporary installation opening 38 and is temporarily locked.
  • the locking convex portion 88 protrudes into the cavity 44 and locks in the recessed portion of the terminal 10 in a detachable manner.
  • the temporary locking convex portion 88 moves beyond the terminal 10 to release the temporary lock on the terminal 10.
  • the retainer main body 82 is attached to the main attachment opening 36, and the locking protrusion 83 protrudes into the cavity 44 and locks into the recess of the terminal 10.
  • the lance 86 can be temporarily locked to the terminal 10 with the retainer 80 located at the temporary attachment position.
  • the retainer 80 is pushed and moved to the final mounting position, the temporary locking between the lance 86 and the terminal 10 is released, and the locking convex portion 83 temporarily locks the terminal 10.
  • the lance 86 and the locking protrusion 83 are at the same position or at least partially overlap in the extending direction of the terminal 10, the lance 86 and the locking protrusion 83 are in the same position in the recess 14 of the terminal 10. It is easy to realize a locking configuration.
  • the temporary locking convex portion 88 has a first guide surface 88f1 and a second guide surface 88f2. Therefore, when the terminal 10 is inserted into the cavity 44 with the retainer 80 located at the temporary attachment position, the terminal 10 can come into contact with the first guide surface 88f1. Thereby, the lance 86 is easily elastically deformed in the direction of retreating from the cavity 44. When the terminal 10 is further pushed in, the lance 86 elastically returns to its original shape, and the temporary locking protrusion 88 can temporarily lock the terminal 10.
  • the retainer 80 when the retainer 80 is pushed from the temporary mounting position to the main mounting position, the second guide surface 88f2 comes into contact with the terminal 10, and the lance 86 can easily be elastically deformed in the direction of retreating from the cavity 44. Therefore, the temporary locking convex portion 88 passes over the terminal 10, and the temporary locking between the lance 86 and the terminal 10 is released. This makes it easy to temporarily lock the lance 86 to the terminal 10 by inserting the terminal 10, and to release the temporary lock between the lance 86 and the terminal 10 by pushing the lance 86.
  • the locking protrusion 83 can be easily locked in the recess 14.
  • the lance may maintain a state in which it is temporarily locked in the terminal 10.
  • the housing 30 includes an outer wall 43a as a vertical wall, and the temporary mounting opening 38 is formed in the outer wall 43a as a slit along the protruding direction of the locking wall portion 84. Therefore, the retainer 80 is guided by the configuration in which the lance 86 is arranged in the slit-shaped temporary attachment opening 38. Furthermore, the lance 86 is easily elastically deformed by utilizing the space within the slit.
  • the temporary attachment opening 38 is formed in the outer wall 43a, it is easy to secure a space in which the lance 86 can be elastically deformed outside the outer wall 43a. Thereby, even if the temporary locking convex portion 88 is sufficiently protruded into the cavity 44, the lance 86 can be largely elastically deformed outward. By sufficiently protruding the temporary locking convex portion 88 into the cavity 44, it is easy to maintain the state in which the lance 86 is temporarily locked to the terminal 10.
  • a slit-shaped opening 38 for temporary attachment crosses the locking part 47 for temporary attachment and the locking part 46 for permanent attachment. Therefore, near the position where the lance 86 is guided by the opening 38 for temporary attachment, the retaining convex portion 85 of the locking wall portion 84 locks with the locking portion 47 for temporary attachment or the locking portion 46 for permanent attachment. Therefore, the retaining convex portion 85 of the retaining wall portion 84 can be smoothly engaged with the temporary attaching retaining portion 47 or the permanent attaching retaining portion 46.
  • the locking area between the retaining protrusion 85 and the main mounting locking part 46 is intermediate.
  • the locking protrusion 83 locks onto the terminal 10. Therefore, the terminal 10 is more firmly prevented from coming off by the locking convex portion 83.
  • the connector may have three or more cavities lined up.
  • an opening for temporary attachment may be formed in the wall that partitions the cavity, and the lance may be placed within the opening for temporary attachment.
  • the above configuration is also applicable to a configuration in which terminals inserted into cavities in multiple stages are prevented from coming off by the same retainer.
  • the retainer main body 82, the locking protrusion 83, and the lance 86 may be provided in multiple stages corresponding to each stage.
