In other words, the first connection portion 146, the first base 135, the first elastic piece 133, the second base 136, and the second connection portion 149 are sequentially connected in the X-axis direction.

Referring to fig. 6, when the plug assembly is installed in the accommodating cavity 111, the first connecting portion 146 abuts against the cavity side surface 112 of the accommodating cavity 111, and the second connecting portion 149 abuts against the cavity side surface 112 of the accommodating cavity 111. Thereby, the connection member 130 is electrically connected with the terminal body 110, and thus, the terminal is electrically connected with the socket terminal 200.

Specifically, referring to fig. 6, the first connection portion 146 includes a first electrical connection portion 147 and a first step portion 148, the first step portion 148 is disposed between the first electrical connection portion 147 and the first base portion 135 along the X-axis direction, one end of the first step portion 148 is fixed to one end of the first electrical connection portion 147, the other end of the first step portion 148 is bent inward of the plugging channel 131, one bent end of the first step portion 148 is fixed to one side of the first base portion 135 facing away from the first elastic sheet 133, the first electrical connection portion 147, the first step portion 148 and the first base portion 135 are connected in a Z-shape, and a height difference H is formed between an outer surface of the first electrical connection portion 147 and an outer surface of the first base portion 135.

Referring to fig. 3, the height difference H is greater than or equal to the thickness D of the third base 164 and the fourth base 165, and when the supporting member 160 is sleeved on the outer circumference of the connecting member 130, the third base 164 is stacked with the first base 135, and the outer surface of the third base 164 is not higher than the outer surface of the first electrical connection portion 147. The fourth base 165 is laminated with the second base 136, and an outer surface of the fourth base 165 is not higher than an outer surface of the second electrical connection 151. The plug assembly 120 is compact, and the volume of the connecting device is reduced.

When the plug assembly 120 is installed into the accommodating cavity 111 of the terminal body 110, the first electrical connection portion 147 and the second electrical connection portion 151 abut against the cavity side surface 112 of the accommodating cavity 111, and since the outer surfaces of the third base portion 164 and the fourth base portion 165 are not higher than the outer surfaces of the first electrical connection portion 147 and the second electrical connection portion 151, the first electrical connection portion 147 and the second electrical connection portion 151 cannot abut against the cavity side surface 112, so that the plug terminal 200 can be directly electrically connected with the terminal body 110 through the connecting piece 130, and further, the electrical connection between the plug terminal 200 and the terminal 100 is ensured to be more stable.

In some embodiments, referring to fig. 4, the number of the first connection portions 146 and the second connection portions 149 is plural, and the plurality of the first electrical connection portions 147 and the plurality of the second electrical connection portions 151 are in contact with the cavity side surface 112 of the accommodating cavity 111, so that the electrical connection between the socket assembly 120 and the terminal body 110 is more stable, and further, the connection between the socket terminal 200 and the terminal 100 is more stable.

In some embodiments, referring to fig. 6, in a natural state, the outer diameter of the plug assembly 120 is larger than the inner diameter of the receiving cavity 111 of the terminal body 110. When the plug assembly 120 is installed in the receiving cavity 111, the elasticity of the connecting member 130 and the supporting member 160 may be utilized to apply a force at the notch positions of the connecting member 130 and the supporting member 160, the notch 141 and the notch 169 are reduced along the radial direction of the plug assembly 120, the outer diameter of the plug assembly 120 is reduced, and when the outer diameter of the plug assembly 120 is smaller than the inner diameter of the receiving cavity 111, the plug assembly 120 is installed in the receiving cavity 111.

After the plug assembly 120 is installed into the receiving cavity 111, the plug assembly 120 automatically expands, which means that the plug assembly 120 tends to increase in outer diameter. The first electrical connection portion 147 and the second electrical connection portion 151 abut against the cavity side surface 112 of the accommodating cavity 111 to electrically connect the plug assembly 120 and the terminal body 110. Because the outer diameter of the plug assembly 120 is greater than the inner diameter of the receiving cavity 111, the plug assembly 120 cannot be fully deployed. The socket assembly 120 maintains a deformed state, and further generates a force towards the cavity side surface 112, and the force becomes a forward force that the first electrical connection portion 147 and the second electrical connection portion 151 can give to the cavity side surface 112 of the accommodating cavity 111, so that the first electrical connection portion 147 and the second electrical connection portion 151 are directly abutted against the cavity side surface 112 of the accommodating cavity 111, so that the electrical connection between the first electrical connection portion 147 and the second electrical connection portion 151 and the terminal body 110 is more stable, and further the stability of the electrical connection between the socket terminal 200 and the terminal 100 is ensured.

In some embodiments, referring to fig. 6, a cavity side surface 112 of the accommodating cavity 111 of the terminal body 110 is concavely formed with a first groove 118, and a groove wall surface of the first groove 118 includes a first cavity side surface 115, a first step surface 114 and a second step surface 116. The first cavity side 115 is located between the first step surface 114 and the second step surface 116, the first step surface 114 and the second step surface 116 being perpendicular to the first cavity side 115.

When the plug assembly 120 is installed in the accommodating cavity 111, the plug assembly 120 is fixed in the first groove 118, the first electrical connection portion 147 and the second electrical connection portion 151 are abutted against the first cavity side surface 115, one end of the first electrical connection portion 147, which is away from the first base portion 135, is abutted against the first step surface 114, one end of the second electrical connection portion 151, which is away from the second base portion 136, is abutted against the second step surface 116, and the plug assembly 120 is limited through the first step surface 114 and the second step surface 116, so that the plug assembly 120 is prevented from being loosened in the plug terminal 200 plugging process, and the stability of connection between the plug terminal 200 and the terminal 100 is improved.

In some embodiments, the material of the connecting member 130 includes copper, and the material of the supporting member 160 includes steel. The copper material has high conductivity, and ensures that the connection member 130 can satisfy the transmission of a large current. The strength of the steel is high, and the supporting member 160 has sufficient strength to support the connecting member 130, preventing the first elastic piece 133 from being deformed, so that the connection of the socket terminal 200 and the terminal 100 is more stable.

Specifically, the material of the connecting piece 130 is selected from conventional copper materials, and the material with high conductivity and high strength is not required, and the material of the supporting piece 160 can be selected from stainless steel 301 or stainless steel 304, so that the strength is high, the high temperature resistance is realized, the cost is one tenth of that of the beryllium copper which is a common material in the prior art, the cost is reduced, and the effect is better.

Fig. 7 and 8 are schematic views of the unfolded structure of the connection member 130 and the support member 160, respectively. When the connecting member 130 and the supporting member 160 are manufactured, the sheet is punched into the structure illustrated in fig. 7 and 8, and then rolled into a circular structure.
