In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection, it can be a direct connection, it can be an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] A conductive reed of this embodiment is installed inside the female conductor 1 and keeps close contact with the female conductor 1 when in use. When the female conductor 1 is connected to the male conductor 2, the male conductor 2 is inserted into the conductive reed 3, and the conductive reed 3 is in close contact with the male conductor 2.

[0023] See also Figure 1-Figure 5 The conductive spring piece 3 is an integrally formed structure, which is convenient for processing; the conductive spring piece 3 has two wall plates 30 arranged opposite to each other up and down, and a plug-in cavity is formed between the two wall plates 30. The front end of the plug-in cavity is an opening for inserting the male end conductor 2 into the plug-in cavity. A plurality of elastic members 33 are integrally provided on each wall plate 30, wherein each elastic member 33 is curved in a wave shape and both ends are connected to the wall plate 30 where it is located as a whole. A corner facing the plug-in cavity is provided on each elastic member 33 as a contact suitable for contacting the male end conductor 2. The contact pin 330, whose corner facing outside the plug-in cavity serves as a fulcrum portion 331 suitable for abutting against the inner wall of the female-end conductor 1, is provided with a plurality of wavy elastic members 33, so that the contact pin 330 forms contact with the male-end conductor 2, and the fulcrum portion 331 abuts against the inner wall of the female-end conductor 1 to provide good support for the elastic member 33, thereby strengthening the clamping force of the elastic member 33 on the male-end conductor 2, thereby ensuring that the contact pin 330 maintains good contact with the male-end conductor 2, and has excellent electrical conductivity and better durability.

[0024] See also Figure 2, multiple elastic members 33 are spaced apart along the width direction of the wall plate 30, and gaps are formed between adjacent elastic members 33. The existence of the gaps can serve as heat dissipation channels to facilitate heat dissipation and prevent excessive temperature rise at the contact part. In order to improve the conductive performance between the elastic member 33 and the female conductor 1, at least two contact pins 330 and at least one fulcrum 331 are provided on each elastic member 33. Figure 3 In the example shown, each elastic member 33 is provided with two contact legs 330 and a fulcrum portion 331 .

[0025] Combination Figure 3 and Figure 5 As shown, a guide member 32 is integrally provided at the front end edge of each wall panel 30, and the guide member 32 includes an arc portion 320 connected to the front end edge of the wall panel 30 and bent inwardly, and a straight portion 321 extending from the end of the arc portion 320 toward the plug-in cavity, and the end of the straight portion 321 is bent toward the wall panel 30 where it is located to form a support portion 322. An insertion channel for the male conductor 2 to pass through is provided between the two guide members 32, and preferably the insertion channel has an entry angle θ, 0°<θ<90°; the guide member 32 can provide a guide for the insertion of the male conductor 2, and the contact between the guide member 32 and the male conductor 2 can also improve the electrical conductivity. Since the male conductor 2 will squeeze the guide member 32 when inserted through the insertion channel, the existence of the support portion 322 can support the guide member 32, so that the guide member 32 can be reset in time after losing the squeezing of the male conductor 2. Furthermore, as Figure 2 As shown, openings 323 are arranged at intervals along the length direction of the arc portion 320. The openings 323 can weaken the strength of the corresponding parts, which is beneficial to the bending and forming of the guide member 32. The openings 323 can also connect the inside of the plug-in cavity with the outside world to achieve ventilation and heat dissipation.

[0026] See also Figure 2 The two wall plates 30 are provided with a plurality of protruding points 34 which are suitable for abutting against the inner wall of the female end conductor 1 and protruding outwards. The protruding points 34 can keep the conductive spring piece 3 and the female end conductor 1 in close connection.

[0027] See also Figure 2 The side, bottom and top surfaces of the conductive spring piece 3 are provided with buckles 31, and the buckles 31 are buckled with the female end conductor 1, which has a simple structure and is convenient and reliable to assemble.

[0028] The conductive spring piece 3 is preferably made of copper sheet. In addition, the conductive spring piece 3, the elastic member 33, the guide member 32 and the buckle 31 are integrally stamped and formed, which is convenient for processing and has low assembly cost.

[0029] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
