[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of Chinese Patent Application No. CN202311285020.3, filed with the China National Intellectual Property Office on September 28, 2023, the entire disclosure of which is incorporated herein by reference.
[0002] The present invention relates to a terminal and an electrical connection assembly including the terminal. [Background technology]
[0003] In the prior art, it is sometimes necessary to simultaneously install multiple terminals on a circuit board, and multiple mating plugs are suitable for respectively inserting into multiple terminals to electrically contact the multiple terminals. In order to simultaneously insert multiple mating plugs into multiple terminals, the installation position error of each terminal should be small or zero, otherwise, multiple mating plugs cannot be simultaneously inserted into multiple terminals. However, in practical applications, the installation position of the terminals always has a certain degree of error, making it difficult to achieve high accuracy. This makes it difficult to simultaneously insert multiple mating plugs into multiple terminals, and greatly increases the difficulty of the mating operation of the product. Therefore, in the prior art, the accuracy of the installation position of the terminals must be improved to reduce the difficulty of mating, which leads to a significant increase in costs.

Figure 3 shows an exemplary plan view of a terminal according to an exemplary embodiment of the present invention. Figure 4 shows a plan cross-sectional view of a terminal according to an exemplary embodiment of the present invention, in which a mating plug and a circuit board are shown.
[0043] As shown in Figs. 1 to 4, in an exemplary embodiment of the present invention, a terminal is disclosed. The terminal includes a horizontal plate 1, a first resilient arm 3, and a second resilient arm 3'. The horizontal plate 1 has a first side edge and a second side edge that are opposite to each other in a first horizontal direction Y. One end of the first resilient arm 3 is connected to the first side edge of the horizontal plate 1, and the other end of the first resilient arm 3 is adapted to be fixed to a circuit board 6. One end of the second resilient arm 3' is connected to the second side edge of the horizontal plate 1, and the other end of the second resilient arm 3' is adapted to be fixed to the circuit board 6.
[0044] 1 to 4, in the illustrated embodiment, the first resilient arm 3 and the second resilient arm 3' are suitable for clamping a mating plug 5 inserted between the first resilient arm 3 and the second resilient arm 3' to make electrical contact with the mating plug 5. When the other end of the first resilient arm 3 and the other end of the second resilient arm 3' are fixed to a circuit board 6, the horizontal plate 1 is suspended above the circuit board 6 by the first resilient arm 3 and the second resilient arm 3'.
[0045] 1 to 4, in the illustrated embodiment, the terminal has a vertical plane of symmetry P, which extends along a second lateral direction X and a vertical direction Z perpendicular to the first lateral direction Y. The first resilient arm 3 and the second resilient arm 3' are symmetrically arranged on either side of the vertical plane of symmetry P.
[0046] 1 to 4, in the illustrated embodiment, the first resilient arm 3 includes a first contact arm 31, which is bent into a V-shape and one end of which is connected to a first side edge of the horizontal plate 1. The second resilient arm 3' includes a second contact arm 31', which is bent into a V-shape and one end of which is connected to a second side edge of the horizontal plate 1. The first contact arm 31 and the second contact arm 31' are used to clamp the inserted mating plug 5 and make electrical contact with both sides of the mating plug 5.
[0047] 1-4, in the illustrated embodiment, the first contact arm 31 has a first contact portion 31a that is used to make electrical contact with one side of an inserted mating plug 5. The second contact arm 31' has a second contact portion 31a' that is used to make electrical contact with the other side of an inserted mating plug 5.
[0048] 1 to 4, in the illustrated embodiment, the first elastic arm 3 further includes a first connecting arm 32, which is bent into a U-shape and connected to the other end of the first contact arm 31. The second elastic arm 3' includes a second connecting arm 32', which is bent into a U-shape and has one end connected to the other end of the second contact arm 31'. The other end of the first connecting arm 32 and the other end of the second connecting arm 32' are interconnected and used for connecting to a circuit board 6.
[0049] As shown in Figures 1 to 4, in the illustrated embodiment, when the mating plug 5 is inserted centered between the first contact arm 31 and the second contact arm 31' (i.e., along the vertical mating plane P), the first contact arm 31 is not in contact with the first connecting arm 32, and the second contact arm 31' is not in contact with the second connecting arm 32'. When the mating plug 5 is inserted between the first contact arm 31 and the second contact arm 31' while being tilted toward the first contact arm 31, one end 31b (the upper end in Figure 4) of the first contact arm 31 is in contact with the first connecting arm 32, while the second contact arm 31' is not in contact with the second connecting arm 32'. At this time, the contact force between the first contact arm 31 and the mating plug 5 may be increased.

At this time, the contact force between the second contact arm 31' and the mating plug 5 may increase.
[0050] However, the present invention is not limited to the illustrated embodiment. For example, in another exemplary embodiment of the present invention, when the mating plug 5 is not inserted between the first contact arm 31 and the second contact arm 31', the first contact arm 31 is not in contact with the first connecting arm 32, and the second contact arm 31' is not in contact with the second connecting arm 32'. When the mating plug 5 is inserted between the first contact arm 31 and the second contact arm 31', one end 31b of the first contact arm 31 is in contact with the first connecting arm 32, and one end 31b' of the second contact arm 31' is in contact with the second connecting arm 32'. In this way, the contact force between the first contact arm 31 and the mating plug 5 and the contact force between the second contact arm 31' and the mating plug 5 can be increased.
[0051] In another exemplary embodiment of the present invention, when the mating plug 5 is not inserted between the first contact arm 31 and the second contact arm 31', one end 31b of the first contact arm 31 is in contact with the first connecting arm 32, and one end 31b' of the second contact arm 31' is in contact with the second connecting arm 32'. This can increase the contact force between the first contact arm 31 and the mating plug 5 and the contact force between the second contact arm 31' and the mating plug 5.
[0052] 1 to 4, in the illustrated embodiment, at least one first partition groove 301 is formed in the first elastic arm 3, and each first partition groove 301 extends from one end to the other end of the first elastic arm 3 to increase the elasticity of the first elastic arm 3.
