Connecting structure having a regulating portion to control deformation of an elastic portion of a terminal in an electrical connector

1. A connecting structure, comprising:

an electrical connector,

wherein said electrical connector includes:

a housing;

a terminal held with the housing; and

a regulating portion,

said housing includes a fixed housing to be fixed to an electrical circuit board and a movable housing configured to be movable relative to the fixed housing,

said movable housing is configured to accommodate a mating connecting member,

said terminal includes a connecting portion to be connected to the electrical circuit board on one end portion thereof and a contact portion to be contacted with the mating connecting member on the other end portion thereof,

said terminal further includes a fixed side held portion held with the fixed housing, a movable side held portion held with the movable housing, and an elastic portion connecting the fixed side held portion and the movable side held portion, and configured to be capable of elastically deforming,

said regulating portion is disposed on the fixed housing and the movable housing for regulating the elastic portion from elastically deforming within a specific elastic deformation range in a direction that the electrical connector is fitted, and

said elastic portion is configured to have a specific spring force when the elastic portion is elastically deformed to a maximum elastic deformation amount within the specific elastic deformation range so that the spring force is smaller than a holding force between the contact portion of the terminal and the mating connecting member in a direction that the electrical connector is pulled out when the electrical connector is connected to the mating connecting member.

2. The connecting structure according to claim 1 , wherein said regulating portion includes a first regulating portion and a second regulating portion,

said first regulating portion is configured to set one limit of the specific elastic deformation range,

said second regulating portion is configured to set the other limit of the specific elastic deformation range.

3. The connecting structure according to claim 2 , wherein said first regulating portion includes a portion of the fixed housing or a first fixed side member attached to the fixed housing, and a portion of the movable housing or a first movable side member attached to the movable housing, and

said first regulating portion is configured to set the one limit of the specific elastic deformation range when the portion of the fixed housing or the first fixed side member abuts against the portion of the movable housing or the first movable side member when the elastic portion elastically deforms in the direction that the electrical connector is pulled out.

4. The connecting structure according to claim 2 , wherein said second regulating portion includes a portion of the fixed housing or a second fixed side member attached to the fixed housing, and a portion of the movable housing or a second movable side member attached to the movable housing, and

said second regulating portion is configured to set the other limit of the specific elastic deformation range when the portion of the fixed housing or the second fixed side member abuts against the portion of the movable housing or the second movable side member when the elastic portion elastically deforms in the direction that the electrical connector is pulled out.
