Can be done.

  Thus, when the plug-side fitting portion 112 is inserted back and forth with respect to the receptacle-side fitting portion 23, a backward force acts on the receptacle-side fitting portion 23 (movable housing 20). At this time, as shown in FIG. 5, the contact surface 22 c of the movable housing 20 becomes the contact surface 16 a of the fixed housing 10, and the rear contact surface 25 b of the movable housing 20 is the rear contact of the fixed housing 10. A rearward force acting on the movable housing 20 is received by contacting the surface 15d. When the mated plug connector 100 is removed from the receptacle connector 1, a forward force acts on the receptacle-side fitting portion 23 (movable housing 20). At this time, the front contact surface 25a of the movable housing 20 contacts the front contact surface 15c of the fixed housing 10, and the forward force acting on the movable housing 20 is received.

  By the way, the upper intermediate portion 38 and the lower intermediate portion 48 of the receptacle connector 1 are plastically deformed when deformed beyond a predetermined range. Therefore, the upper intermediate portion 38 and the lower intermediate portion 48 are deformed within a predetermined range (elastically deformable). Range). Therefore, the receptacle connector 1 has a configuration in which the upper intermediate portion 38 and the lower intermediate portion 48 are deformed in an elastically deformable range by restricting the moving range of the movable housing 20, and the configuration will be described below. To do.

  First, the structure which controls the moving range to the right and left of the movable housing 20 is demonstrated. As shown in FIGS. 2 and 4, the receptacle-side fixing metal fitting 50 is attached to the fixing housing 10, and the intermediate portion 53 is located in the metal fitting receiving recess 26. For this reason, the movable housing 20 is allowed to move to the left and right by the gap between the recess side surface 26 a and the intermediate portion 53 in the left-right direction. Movement is restricted.

  Next, a configuration for regulating the downward movement range of the movable housing 20 will be described. As shown in FIG. 2, when a plurality of receptacle contacts 30 are attached across the fixed housing 10 and the movable housing 20, the lower contact surface 15e of the fixed housing 10 and the lower contact surface 25c of the movable housing 20 However, it is held in a state having a gap above and below. Therefore, the movable housing 20 is allowed to move downward by the gap between the lower contact surface 15e and the lower contact surface 25c in the vertical direction, but the lower contact surface 25c is allowed to move downward. Further downward movement is restricted by contacting the surface 15e.

  Next, a configuration for regulating the upward movement range of the movable housing 20 will be described. As shown in FIGS. 2 and 4, the receptacle-side fixing metal fitting 50 is attached to the fixing housing 10, and the intermediate portion 53 is located in the metal fitting receiving recess 26. Therefore, the movable housing 20 is allowed to move upward by a gap between the concave bottom surface 26 b and the intermediate portion 53 (the lower surface of the intermediate portion 53) in the vertical direction, but the concave bottom surface 26 b abuts on the intermediate portion 53. As a result, further upward movement is restricted.

  5, the receptacle connector 1 includes a contact surface 22c and a contact surface 16a, a rear contact surface 25b and a rear contact surface 15d, a front contact surface 25a and a front contact surface 15c. However, each is assembled in a state having a gap in the front and rear. Further, as described above, the movable side movement restricting portion 25 is held in the receiving space 15a with a gap in the vertical direction. Therefore, when a downward force is applied to the front portion of the movable housing 20, the movable side movement restricting portion 25 swings in the receiving space 15 a, and the inner surface of the fixed side movement restricting portion 15 or the receptacle side fixing metal fitting 50. Peristaltic movement is allowed within a range up to contact with the intermediate portion 53. Then, when the movable side movement restricting portion 25 swings and contacts the inner surface 53 of the fixed side movement restricting portion 15 or the intermediate portion 53 of the receptacle side fixing bracket 50, the movable housing 20 swings obliquely downward beyond that position. Is regulated.

  Further, even when an upward force acts on the front portion of the movable housing 20, the movable side movement restricting portion 25 is in contact with the inner surface 53 of the fixed side movement restricting portion 15 or the intermediate portion 53 of the receptacle side fixing bracket 50. Within the range, the movable housing 20 is allowed to swing obliquely upward. When the movable side movement restricting portion 25 swings and contacts the inner surface of the fixed side movement restricting portion 15 or the intermediate portion 53 of the receptacle side fixing bracket 50, the movable housing 20 swings obliquely upward beyond that position. Is regulated.

  As described above, the receptacle connector 1 is configured such that the movable housing 20 is movable with respect to the fixed housing 10 by using the elastic deformation of the receptacle contacts 30 (the upper contact 30a and the lower contact 30b). For this reason, the receptacle connector 1 is required to have a configuration that prevents contact between the upper contact 30a and the lower contact 30b that are elastically deformed. Therefore, the receptacle connector 1 is provided with a contact restricting protrusion 14 on the bottom surface of the fixed housing 10 for maintaining a front-rear distance between the first bent portion 33a and the first bent portion 43a (see FIGS. 3 and 7). The contact regulating protrusion 14 prevents contact between the upper contact 30a and the side contact 30b in the vicinity of the first bent portion 33a and the first bent portion 43a.

  In addition, when the receptacle connector 1 is viewed from the side surface shown in FIG. 5, the center line C1 in the front-rear direction of the fixed side movement restricting portion 15 and the movable side movement restricting portion 25 is the center line in the front and rear direction of the entire receptacle connector 1. It is comprised so that it may be located behind C2. For this reason, the receptacle connector 1 can be configured to be able to secure the front-rear width of the receptacle-side fitting portion 23 while reducing the front-rear width.

  In the above-described embodiment, as the upper contact 30a and the lower contact 30b, the configuration in which the intermediate portions 38 and 48 have a total of three bent portions has been described as an example. A configuration having two or more bent portions may be used.

  In the above-described embodiment, the example in which the present invention is applied to the receptacle connector in which the movable housing is movable with respect to the fixed housing among the receptacle connector and the plug connector configured to be fitted with each other has been described. Alternatively, the plug connector may be configured such that the movable housing can move relative to the fixed housing, and the present invention can be applied to the plug connector.
