Claims (9)

  1. A terminal having a mating portion, wherein the mating portion has a contact portion and a protective portion. The aforementioned contact portion is a part that includes a contact point with other terminals housed in the mating portion, The protective portion is provided in the opening of the fitting portion. The contact portion and the protective portion are positioned to face each other. At least one of the contact portion and the protective portion has two or more branched legs, The contact portion has two legs, a first leg and a second leg, as the branched legs. In a plan view, at least a portion of the protective portion is positioned between the first leg portion and the second leg portion of the contact portion, and/or A terminal in which the protective portion has two legs, a first leg and a second leg, as the branched legs, and at least a part of the contact portion is positioned between the first leg and the second leg of the protective portion in a plan view .
  2. The terminal according to claim 1 , wherein, in a plan view, the tip of the first leg of the contact portion and/or the tip of the second leg of the contact portion are spaced apart from the tip of the protective portion.
  3. The terminal according to claim 1 , wherein, in a cross-sectional view in the thickness direction, the tip of the first leg of the contact portion and/or the tip of the second leg of the contact portion are positioned lower than the tip of the protective portion.
  4. The terminal according to claim 1 , having a recess provided so that the protective portion does not come into contact with the other terminals.
  5. The terminal according to claim 1 , wherein the first leg and the second leg of the contact portion are joined together to form a ring.
  6. The terminal according to claim 1 , wherein, in a plan view, the tip of the first leg of the protective portion and/or the tip of the second leg of the protective portion are spaced apart from the tip of the contact portion.
  7. The terminal according to claim 1 , wherein, in a cross-sectional view in the thickness direction, the tip of the first leg of the protective portion and/or the tip of the second leg are positioned higher than the tip of the contact portion.
  8. The terminal according to claim 1 , wherein the contact portion is made of an elastic member so as to press against the other terminal.
  9. The terminal according to claim 8, wherein the elastic member has a free end and a fixed end, the free end has the contact portion, the fixed end is fixed to the fitting portion, and the contact portion provided on the free end is configured to displace and press against the other terminal while the other terminal is being accommodated in the fitting portion .

Description

This disclosure relates to terminals used for electrical connections. More specifically, this disclosure relates to terminals having mating portions for coupling with other terminals (more specifically, receptacle terminals, for example). As an example of a terminal having a mating portion, Patent Document 1 discloses a receptacle terminal that utilizes a contact spring. Special Publication No. 2013-508935 Figure 1 is a schematic diagram illustrating the mating portion of a terminal according to one embodiment of the present disclosure (first embodiment).Figure 2 is a schematic top view illustrating the relationship between the contact portion and the protective portion in the mating portion of a terminal according to the first embodiment of this disclosure.Figure 3 is a schematic top view illustrating the relationship (modified example) between the contact portion and the protective portion in the mating portion of a terminal according to the first embodiment of this disclosure.Figure 4 is a schematic diagram illustrating the "oblique insertion" of one terminal into the mating portion of another terminal according to the first embodiment of this disclosure (before insertion).Figure 5 is a schematic diagram illustrating the "oblique insertion" of one terminal into the mating portion of another terminal according to the first embodiment of this disclosure (during insertion).Figure 6 is a schematic diagram illustrating the insertion of another terminal into the mating portion of a terminal according to the first embodiment of this disclosure (before insertion).Figure 7 is a schematic diagram illustrating a state in which another terminal is inserted into the mating portion of a terminal according to the first embodiment of this disclosure and coupled to one another (mating state).Figure 8 is a schematic diagram showing a terminal mating portion according to another embodiment of the present disclosure (second embodiment).Figure 9 is a schematic top view illustrating the relationship between the contact portion and the protective portion in the mating portion of a terminal according to the second embodiment of this disclosure.Figure 10 is a schematic top view illustrating the relationship (modified example) between the contact portion and the protective portion in the mating portion of a terminal according to the second embodiment of this disclosure.Figure 11 is a schematic diagram illustrating the "oblique insertion" of one terminal into the mating portion of another terminal according to the second embodiment of this disclosure (before insertion).Figure 12 is a schematic diagram illustrating the "oblique insertion" of one terminal into the mating portion of another terminal according to the second embodiment of this disclosure (during insertion).Figure 13 is a schematic diagram illustrating the insertion of another terminal into the mating portion of a terminal according to the second embodiment of this disclosure (before insertion).Figure 14 is a schematic diagram illustrating a state in which another terminal is inserted into the mating portion of a terminal according to the second embodiment of this disclosure and coupled to one another (mating state).Figure 15 is a schematic diagram illustrating the conventional terminal mating portion (conventional configuration).Figure 16 is a schematic diagram illustrating the insertion of another terminal into the mating portion of the previous terminal (before insertion).Figure 17 is a schematic diagram illustrating the state in which another terminal is inserted into the mating portion of the previous terminal and connected to it (mating state).Figure 18 is a schematic diagram illustrating the "diagonal insertion" of one terminal into the mating portion of the previous terminal (before insertion).Figure 19 is a schematic diagram illustrating the "diagonal insertion" of one terminal into the mating portion of the previous terminal (during insertion). The terminals of this disclosure are terminals for electrical connection. In particular, this disclosure relates to terminals having a mating portion for providing an electrical connection (hereinafter, the terminals of this disclosure may be referred to as "receptacle terminals" or "female terminals"). In the terminals of this disclosure, the mating portion comprises at least a contact portion and a protective portion (see Figures 1 and 8). In this disclosure, "terminal" means a component or material that, together with other terminals, contributes to an electrical connection. In this disclosure, “mating portion” means a portion or part that can receive and accommodate at least a part of another terminal. The terminals of this disclosure and other terminals only need to engage or combine with each other, and do not necessarily need to be in a strictly fitted manner that is completely or tightly mated. In short, the mating portion can be said to be any portion or part of a terminal that is used for engaging or combining
