[0063] Figure 15 It is a perspective view showing the structure of an electrical connector (plug connector) according to Embodiment 2 of the present invention, Figure 16 is the main view, Figure 17 Yes Figure 16 A cross-sectional view of the B-B section.

[0064] Compared with the above-described first embodiment, the second embodiment of the present invention does not have a recessed portion filled with a part of the housing 210 between the contact portion and the mounting portion of the terminals 220 and 230 . Instead, a part of the housing (the terminal fixing part 213 ) is in close contact with and covers the fitting direction (Z 1 direction) surface. The configuration of the other parts is the same as that of the above-described first embodiment, and therefore, overlapping descriptions are omitted.

[0065]The electrical connector according to the second embodiment is a plug connector 200 mounted on a substrate 500 such as a printed circuit board, and includes an...

Abstract

Provided is an electrical connector which satisfies the requirements for lightness, thinness, shortness and miniaturization of an electronic device, suppresses the resistance of a conductive terminal to be low, and can cope with an increase in the current flowing through the conductive terminal. An electrical connector such as a plug connector (100) is provided with an insulating housing (110) and a conductive terminal (120, 130) fixed to the housing (110), the terminal (120, 130) including a mounting portion (121, 131, 132) connected to a substrate (500) and a contact portion (122, 133) protruding from the mounting portion (121, 131, 132) in a fitting direction (Z1 direction), and the plate thickness (t1) of the contact portion (122, 133) is greater than the plate thickness (t2) of the mounting portion (121, 131, 132) in a direction (Z1Z2 direction) orthogonal to the substrate (500).

Description

technical field [0001] The present invention relates to an electrical connector, and more particularly, to an electrical connector mounted on a substrate. Background technique [0002] Conventionally, a board-to-board type electrical connector has been used as a connector for connecting the surfaces of the boards to each other. In the board-to-board type electrical connector, the plug connector and the receptacle connector are grouped together, and the plug connector is inserted into the receptacle connector to make electrical connection between the conductive terminals (contacts) of each other, thereby forming an electrical connection. As a technique related to such a board-to-board type electrical connector, for example, the technique described in Patent Document 1 (Japanese Patent Laid-Open No. 2017-16897 ) and the like can be mentioned. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2017-16897 [0004] In recent years, with the demand for reduction in thickn...
