Description

Connectors and electronic devices This application claims priority to Japanese Patent Application No. 2021-016954 filed on February 4, 2021, and the entire disclosure of this application is incorporated herein by reference. The present disclosure relates to connectors and electronic devices. Conventionally, as a technology for improving connection reliability with a connected object, a connector having a floating structure is known in which a movable insulator, which is part of the connector, moves to absorb positional misalignment between the connected object and the connector even during and after fitting. Patent Document 1 discloses an electrical connector for a circuit board that can increase the amount of elastic deformation in the elastic part of the terminal while ensuring a low profile by reducing the height dimension of the connector while maintaining the terminal firmly by integral molding with the fixed housing and the movable housing, respectively. This electrical connector for a circuit board has a floating structure. A connector according to one embodiment of the present disclosure is, A first insulator having a pair of first side walls and a bottom wall and formed in a rectangular shape, and A second insulator extending along the longitudinal direction of the first insulator, wherein a portion of the second insulator is disposed in the space enclosed by the pair of first side walls and the bottom wall, and the second insulator is movable relative to the first insulator, and A contact having an elastic portion attached to the first side wall of the first insulator and the second insulator, and positioned between the first insulator and the second insulator to connect the first insulator and the second insulator, and The second insulator and the elastic part are separated from the first insulator in a non-fitted state where the second insulator and the object to be connected are not fitted, and are also facing the bottom wall. The end of the lower wall side in the above elastic part is located on the lower wall side rather than the end of the lower wall side in the above second insulator. An electronic device according to one embodiment of the present disclosure is, The above connector is provided. FIG. 1 is an external perspective view showing a connector according to an embodiment in which a connected object is connected, viewed from the top. FIG. 2 is an external perspective view showing a connector according to one embodiment in a state separated from the object to be connected, as seen from the top. Figure 3 is an external perspective view showing the connector group of Figure 1 as seen from the top. Figure 4 is an exploded perspective view of the top surface of the connector of Figure 3. Figure 5 is a cross-sectional perspective view along the VV arrow line of Figure 3. Figure 6 is a cross-sectional view along the VV arrow line of Figure 3. Figure 7 is an enlarged view of the dashed line enclosed section (VII) of Figure 6. Figure 8 is a cross-sectional view along the arrow line VIII-VIII of Figure 3. FIG. 9 is an external perspective view showing the connection target connected to the connector of FIG. 3 by looking at the top surface. FIG. 10 is an exploded perspective view of the upper surface of the object to be connected in FIG. 9. Figure 11 is a cross-sectional view along the arrow line XI-XI of Figure 1. In a connector having a floating structure, it is required to obtain a sufficient amount of movement of the movable insulator along the mating direction in which the connector and the object to be connected mat with each other. However, the electrical connector for a circuit board described in Patent Document 1 focuses mainly on the movement of the movable insulator along a direction orthogonal to the mating direction, for example, a direction parallel to the circuit board. If the movable insulator moves in the mating direction in the electrical connector for a circuit board described in Patent Document 1, there is a possibility that components of the connector, such as the contact and the movable insulator, may come into contact with the circuit board. This may cause problems such as deformation and breakage of the contact. Due to these problems, the movable characteristics caused by the floating structure of the connector may be degraded. Additionally, there is a possibility that electrical problems such as short circuits may occur when the contact comes into contact with the circuit board. According to a connector and electronic device according to one embodiment of the present disclosure, it is possible to allow movement of the movable insulator in the mating direction while suppressing the degradation of operating characteristics caused by the floating structure and electrical problems in the circuit board. Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the attached drawings. In the following description, the directions of fron
