- the first insulator 20 may have a hole portion 27 that penetrates the bottom plate portion 21 in the vertical direction in the region where the wide portion 44a is arranged in the bottom plate portion 21.
- the first insulator 20 may have a recess formed in the region where the wide portion 44a is arranged in the bottom plate portion 21 instead of the hole portion 27.
- the mounting portion 45a of the first metal fitting 40a mounted on the circuit board CB1 includes the bottom surface of the second base portion 43a on the circuit board CB1 side.
- the mounting portion 45a has a predetermined area in the front-back and left-right directions on the lower surface of the wide portion 44a.
- the mounting portion 45a includes a thick portion along the vertical direction of the wide portion 44a.
- the mounting portion 45a may further include the upper surface of the wide portion 44a.
- the upper surface of the second base portion 43a is located below the upper surface of the bottom plate portion 21.
- the solder is accommodated between the upper surface of the wide portion 44a and the base 81 of the metal fitting 80. Therefore, poor fitting between the first connector 10 and the second connector 50 is suppressed. It is possible to avoid a situation in which the second connector 50 is not completely fitted to the first connector 10 due to the excess solder.
- the mounting portion 45a is located between the short wall 23a and the fitting convex portion 22 in the left-right direction.
- the mounting portion 45a is formed at a position adjacent to the fitting convex portion 22 on the outside of the fitting convex portion 22 in the left-right direction.
- the mounting portion 45a is formed to be wide, the mounting strength of the first connector 10 with respect to the circuit board CB1 is improved.
- the first insulator 20 has the hole portion 27, a side fillet based on solder can be formed, for example, as shown in FIG. As a result, the mounting strength of the first connector 10 with respect to the circuit board CB1 is improved. As a result, the robustness of the first connector 10 is improved.
- the second base portion 43a is formed as a wide portion 44a at the left and right positions overlapping the hole portion 27.
- the second base portion 43a is formed so that the portion extending from the wide portion 44a toward the short wall 23a and in close contact with the bottom plate portion 21 is narrower than the wide portion 44a.
- the wall thickness of the bottom plate portion 21 increases at the portion integrated with the second base portion 43a. Therefore, the strength of the first insulator 20 is improved. As a result, the robustness of the first connector 10 is improved.
- the connector 1, the first connector 10, or the second connector 50 as described above is mounted on an electronic device including the circuit board CB1 and the circuit board CB2.
- Electronic devices include, for example, any communication terminal device such as a smartphone, as well as any information processing device such as a personal computer, copier, printer, facsimile, and multifunction device.
- Electronic devices include any in-vehicle device such as cameras, radars, drive recorders, and engine control units.
- Electronic devices include any other in-vehicle device used in in-vehicle systems such as car navigation systems, advanced driver assistance systems, or security systems. Other electronic devices include any industrial device.
- the robustness of the connector 1 during mating between the first connector 10 and the second connector 50 is improved even in a compact and low profile state. Therefore, the reliability of the electronic device as a product is improved.
