Therefore, even if the other terminal 25 is inserted obliquely (see FIGS. 11B and 12B), the pressure is dispersed to prevent contact between the other terminal 25 and the contact portion 22 .

That is, in a plan view, the leg portions of the protection portion and the contact portions may have a non-overlapping arrangement relationship in which they do not overlap each other in the transverse direction of the terminal. Even in such a case, scraping of the plated layers of the two terminals (20, 25) can be significantly suppressed or reduced.

It is possible to slide and slide on Therefore, it becomes easier to suppress or prevent the tip portion 26 of the other terminal 25 from slipping under the tip portion 22t of the contact portion 22, and it becomes easier to suppress or prevent damage to the plated layer of the other terminal 25. .

Even if the other terminal 25 is inserted obliquely at an angle of 45° or less, the other terminal 25 can be more successfully inserted into the fitting portion (Figs. 11, 12 and 14 (D )reference).
  • the possibility of damaging the two terminals (20, 25) for example, the contact portion 22 of the terminal 20 of the present disclosure, particularly the plating layer of the contact point 22p, can be relatively significantly reduced (FIGS. 11(D) and 12). (D) and FIG. 14(D)). As a result, scraping of the plated layers of the two terminals (20, 25) can be greatly reduced.
  • scraping of the plated layers of the two terminals (20, 25) can be greatly reduced, and physical and electrical contact between the other terminal 25 and the contact portion 22 can be reduced.
  • a contact point 22p can be formed by such contact (see FIG. 14(D)).
  • the resistance values of the two terminals (20, 25) are made easier to stabilize.
  • terminals of the present disclosure have been described in detail in the first and second embodiments, but the terminals of the present disclosure should not be construed as being limited to the first and second embodiments.
  • the configurations or elements described in the first and second embodiments may be used in any suitable combination within the scope of the idea or spirit of the present disclosure.
  • the recess 3c provided in the protect portion 3 of the terminal 10 according to the first embodiment may be formed in the protect portion 23 of the terminal 20 according to the second embodiment. By doing so, scraping of the plated layer can be more easily suppressed.
  • the contact portion may be composed of an elastic member.
  • the contact portion may be composed of an elastic member so as to press or be able to press another terminal (FIGS. 1(D), 7(D), 8(D) and 14(D). reference).
  • “to press the other terminal” means that when the terminal of the present disclosure and the other terminal are combined with each other or when the other terminal is combined, an external force is exerted on the other terminal due to the contact portion. (for example, when another terminal is inserted into the opening of the terminal of the present disclosure, an external force that resists the insertion is exerted on the other terminal).
  • the elastic member may have both a free end and a fixed end, thereby pressing against the other terminal. More specifically, the elastic member has both a free end and a fixed end, the free end has a contact portion, the fixed end is fixed to the fitting portion, and the other terminal is accommodated in the fitting portion. It may be configured such that the contact portion provided at the free end is displaced while the other terminal is pressed (see FIGS. 7(D) and 14(D)). With such a configuration of the terminal of the present disclosure, when the other terminal is accommodated in the fitting portion, it is easier to elastically hold the other terminal in the fitting portion more appropriately. On the other hand, the terminal of the present disclosure can suppress or reduce scraping of the plated layer. That is, according to the terminal of the present disclosure, preferably, it is possible to more successfully achieve both of the two conflicting performances of pressing other terminals and suppressing scraping of the plated layer.
  • the terminal of the present disclosure can be used in a wide range of fields where electrical connections are required.
  • the field of application is not particularly limited, but the terminals of the present disclosure can be used, for example, for electrical connections in the electromechanical field.
  • the terminal of the present disclosure can be utilized in fields where more stabilized resistance and/or pressing force are required, for example, in the field of vehicles such as automobiles, hybrid automobiles, and electric automobiles.
  • the terminals of the present disclosure can be used as terminals for connecting to a vehicle computer such as an ECU. It can also be used in various vehicles and devices including computers.
