The female terminals of traditional high-voltage connectors for electrical connection are arc-shaped spring contact structures. When transmitting large currents, the spring contact points contact the external male terminals to generate contact resistance, which will generate a lot of heat during the long-term transmission of large currents. As the temperature rises, the elasticity of the spring gradually decreases, reducing the pressure applied by the spring to the male terminal, resulting in a continuous increase in heat generation, which affects the current transmission of electrical equipment and even causes equipment failure.

[0043] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like 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 or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0044] In one embodiment of the present invention, Figures 7-8 As shown, a high current contact terminal is provided, which is suitable for a high voltage connector. The high current contact terminal includes a first terminal plate 10 and a second terminal plate 20. The first terminal plate 10 and the second terminal plate 20 are used together to clamp a male terminal that is matched and connected thereto.

[0045] Among them, Figures 1 to 5As shown, the first terminal plate 10 has a first connecting portion 11 and a first contact portion 12 arranged side by side, and the first connecting portion 11 and the first contact portion 12 are arranged side by side and extend in a horizontal direction. The first connecting portion 11 is used to connect with other components such as an insulator, and the first contact portion 12 includes a plurality of first elastic sheets 121 extending in the same direction, each of the first elastic sheets 121 is wavy and forms at least two troughs 12a, and the first elastic sheet 121 is elastic. The arrangement of the plurality of first elastic sheets 121 makes the first contact portion 12 constitute a sheet spring structure, and the troughs 12a arranged thereon are used to contact with the surface of the male terminal, thereby achieving electrical conduction.

[0046] Among them, Figures 1 to 5 As shown, the second terminal plate 20 has a second connection portion 21 and a second contact portion 22 arranged side by side. Similarly, the second connection portion 21 and the second contact portion 22 are arranged side by side and extend in a horizontal direction. The second connection portion 21 is connected to the first connection portion 11, and the second contact portion 22 includes a plurality of second elastic sheets 221 extending in the same direction. Each of the second elastic sheets 221 is wavy and forms at least two wave crests 22a. Similarly, the second elastic sheet 221 is elastic. The arrangement of the plurality of second elastic sheets 221 makes the second contact portion 22 constitute a sheet spring structure, and the wave crests 22a arranged thereon are used to contact the surface of the male terminal, thereby achieving electrical conduction.

[0047] Furthermore, each of the wave crests 22a corresponds to each of the wave troughs 12a and elastically abuts against each other (not shown) or forms a gap (such as Figures 4-5 Even if there is a gap between the crest 22a and the trough 12a, the male terminal 100 can be clamped under the elastic force of the first elastic sheet 121 and the second elastic sheet 221. It can be understood that when the crest 22a and the trough 12a are elastically abutted, it is easier to clamp the male terminal 100.

[0048] The peaks 22a and valleys 12a described in this embodiment are Figures 4-5 The direction shown in FIG. 1 is used as the reference. When the use direction of the high current contact terminal changes according to the actual scene, the defined peak 22a and trough 12a can rotate the position of the high current contact terminal to Figures 4-5 It is understood that the wave crest 22a and the wave trough 12a are expressions of opposite, symmetrical or substantially symmetrical structures formed on the second elastic sheet 221 and the first elastic sheet 121 .

[0049] Specifically, in this embodiment, the first terminal plate 10 and the second terminal are used together to clamp the male terminal, that is, the male terminal can be inserted between the first contact portion 12 and the second contact portion 22 until the trough 12a of each first elastic sheet 121 and the crest 22a of each second elastic sheet 221 respectively abut against the two opposite surfaces of the male terminal, thereby achieving electrical conduction with the male terminal; since the first elastic sheet 121 has at least two troughs 12a in contact with the male terminal, and the second elastic sheet 221 has at least two crests 22a in contact with the male terminal, the entire high-current contact terminal forms more contact points with the male terminal, so that the contact area with the male terminal is larger, the contact resistance generated is smaller, the heat generated during long-term transmission is less, the ability to pass current is enhanced, and the current carrying capacity is enhanced; and, the multiple first elastic sheets 121 and the multiple second elastic sheets 221 respectively correspond to each other and elastically clamp the male terminal, thereby increasing the pressure on the male terminal and maintaining better clamping stability.

[0050] In the high-current contact terminal of the present embodiment, the first contact portion 12 of the first terminal plate 10 and the second contact portion 22 of the second terminal plate 20 together constitute a wave-shaped connection structure, which can maintain a long-lasting and strong clamping elastic force, thereby solving the problem of long-term contact failure between the male terminal and the electrical connection in the prior art.

[0051] In another embodiment of the present invention, Figures 2 to 5 As shown, the first contact portion 12 also includes a first bridge piece 122 connected to the end of each first elastic piece 121, the first bridge piece 122 is perpendicular to the extension direction of each first elastic piece 121, and the first bridge piece 122 can connect the first elastic pieces 121 together, so that the elastic performance of the entire first contact portion 12 can be kept more stable. Similarly, the second contact portion 22 also includes a second bridge piece 222 connected to the end of each second elastic piece 221, the second bridge piece 222 is perpendicular to the extension direction of each second elastic piece 221, that is, the second bridge piece 222 can connect the second elastic pieces 221 together, so that the elastic performance of the entire second contact portion 22 can be kept more stable. In this embodiment, the first bridge piece 122 and the second bridge piece 222 are used to make the arrangement so that each first elastic piece 121 forms an integral wave structure, and each second elastic piece 221 forms an integral wave structure, so that the upper and lower wave structures clamp the male terminal and can maintain a lasting elastic force.

[0052] In another embodiment of the present invention, Figures 1 to 5As shown, a conical opening 100 is formed between the first bridge piece 122 and the second bridge piece 222. The setting of the conical opening 100 is conducive to the insertion of the male terminal, and it is convenient for the male terminal to be inserted between the first elastic piece 121 and the second elastic piece 221 at the conical opening 100. And the first bridge piece 122 and the second bridge piece 222 are inclined in opposite directions respectively. Specifically, the structural design of the first bridge piece 122 and the second bridge piece 222 in opposite directions can effectively guide the insertion of the male terminal, and reduce the accidental collision damage with the first contact part 12 and the second contact part 22 caused by the insertion of the male terminal.

[0053] In another embodiment of the present invention, Figure 3 As shown, the first side of the first connecting part 11 is connected to the first side of the second connecting part 21 by at least one connecting piece 30; that is, on one side, the first connecting part 11 and the second connecting part 21 are connected together by the set connecting piece 30. Usually, two connecting pieces 30 are provided and are arranged at intervals.

[0054] Furthermore, if Figures 2-3 As shown, a hook piece 40 is provided on the second side of one of the first connection part 11 and the second connection part 21. The hook piece 40 is formed by extending the side of the first connection part 11 or the second connection part 21 in a direction perpendicular to the side and bending inward at the end. The inward direction here refers to the direction toward one of the first connection part 11 or the second connection part 21. Further, a notch 50 is provided on the second side of the other of the first connection part 11 and the second connection part 21. The notch 50 is a notch formed inwardly on the side of the first connection part 11 or the second connection part 21, which is located corresponding to the bending part of the end of the hook plate and cooperates with each other. In addition, the hook piece 40 is placed in the notch 50. That is, on the other side, a hook piece 40 is placed in the notch 50, so that the first connection part 11 and the second connection part 21 are connected on this side. In this way, by combining the connection piece 30 and the cooperation between the hook piece 40 and the notch 50 , the first connection portion 11 and the second connection portion 21 are connected at two opposite sides.

[0055] Preferably, two ends of the connecting piece 30 are integrally formed on the first connecting portion 11 and the second connecting portion 21 , respectively.

[0056] In another embodiment of the present invention, Figure 1 and 5As shown, an insert piece 60 is provided at the end of one of the first connection part 11 and the second connection part 21, and a slot 70 is provided at the other of the first connection part 11 and the second connection part 21, and the insert piece 60 is inserted into the slot 70. Specifically, by inserting and connecting the insert piece 60 and the slot 70, the connection between the first terminal board 10 and the second terminal board 20 is further stabilized, that is, a connection is added at the end, combined with the above-mentioned connection piece 30 and the hook piece 40 and the missing groove 50, the first terminal board 10 and the second terminal board 20 are connected in three directions, ensuring that the first terminal board 10 and the second terminal board 20 are not easily deformed, thereby always ensuring that the first contact part 12 and the second contact part 22 have good elastic force to clamp the male terminal.

[0057] In another embodiment of the present invention, Figures 4-5 As shown, the first terminal plate 10 and the second terminal plate 20 are both formed by bending metal plates. Specifically, the first terminal plate 10 and the second terminal plate 20, as well as the connecting piece 30, the hook piece 40 and the insert piece 60 connected between the first terminal plate 10 and the second terminal plate 20 can be directly formed by using the sheet metal integral forming method, thereby improving the production efficiency of manufacturing the high-current terminal and the product quality.

[0058] In another embodiment of the present invention, Figures 1 to 3 As shown in Figure 6, the high-current contact terminal also includes a bracket 80, which is covered on the outer surface of the first terminal plate 10 and the outer surface of the second terminal and clamps the first terminal plate 10 and the second terminal plate 20. The bracket 80 plays the role of a tightening sleeve, and the first terminal plate 10 and the second terminal plate 20 are supported by the bracket 80 to ensure that the entire high-current terminal can fully and tightly contact with the external male terminal, and can maintain a long-term and strong clamping elastic force. In this way, even after a long period of plugging and unplugging, there is no need to worry about the first contact portion 12 of the first terminal plate 10 and the second contact portion 22 of the second terminal plate 20 weakening its elastic force due to deformation, because the clamping force of the first terminal plate 10 and the second terminal plate 20 on the male terminal can be strengthened by the bracket 80.

[0059] In another embodiment of the present invention, Figures 1 to 3 As shown in Figure 6, the bracket 80 includes a first pressing plate 81 and a second pressing plate 82, the first pressing plate 81 is pressed against the upper surface of the first terminal plate 10, and the second pressing plate 82 is pressed against the lower surface of the second terminal plate 20; the first pressing plate 81 and the second pressing plate 82 respectively apply pressure to the first terminal plate 10 and the second terminal plate 20, so that the first terminal plate 10 and the second terminal plate 20 are tightened in facing directions.

[0060] Furthermore, if Figure 6As shown, the first side of the first pressing plate 81 is connected to the first side of the second pressing plate 82 by at least one connecting side plate 83; preferably, there are two connecting side plates 83, for example Figure 1 As shown, the position of the connecting side plate 83 is staggered with the position of the connecting plate, and the connecting side plate 83 connects the first pressing plate 81 and the second pressing plate 82 together on one side. A buckle plate 84 is provided on the second side of one of the first pressing plate 81 and the second pressing plate 82, and the buckle plate 84 is a protrusion formed on a straight plate (e.g., a long straight plate), and a buckle groove 85 is provided on the second side of the other of the first pressing plate 81 and the second pressing plate 82, and the buckle groove 85 is a hole formed on a straight plate (e.g., a short straight plate), so that the positions of the two straight plates correspond to each other, and the buckle plate 84 is buckled in the buckle groove 85 through the cooperation of the protrusion and the hole. Specifically, the connection between the buckle plate 84 and the buckle groove 85 realizes the connection of the other side of the first pressing plate 81 and the second pressing plate 82, and the connection with the connecting side plate 83 respectively constitutes the connection on the opposite sides of the first pressing plate 81 and the second pressing plate 82, and the connection between the buckle plate 84 and the buckle groove 85 is a detachable connection, which can facilitate the installation and disassembly of the entire bracket 80.

[0061] Preferably, the bracket 80 is an integrally formed metal part, that is, the first pressing plate 81, the second pressing plate 82, the connecting side plate 83 and the buckle plate 84 are all integrally formed and connected. The shape of the first pressing plate 81 is similar to that of the first terminal plate 10, and the shape of the second pressing plate 82 is similar to that of the second terminal plate 20.

[0062] In another embodiment of the present invention, Figures 1-2 As shown, the first pressing plate 81 is stamped and formed with a plurality of first pressing pieces 811 pressing against the upper surface of each trough 12a corresponding to the position of the trough 12a of each first elastic sheet 121, and the second pressing plate 82 is stamped and formed with a plurality of second pressing pieces 821 pressing against the lower surface of each crest 22a corresponding to the position of the crest 22a of each second elastic sheet 221. In this embodiment, the shape of the first pressing piece 811 is adapted to the shape of the first elastic sheet 121, so that it can be well attached and pressed against the upper surface of the first elastic sheet 121; similarly, the shape of the second first pressing piece 811 is adapted to the shape of the second elastic sheet 221, so that it can be well attached and pressed against the lower surface of the second elastic sheet 221. By providing a plurality of first pressing pieces 811 and a plurality of second pressing pieces 821, each trough 12a and crest 22a can be kept in good contact with the male terminal inserted therein, thereby improving the electrical connection performance.

[0063] Another embodiment of the present invention provides a high-voltage connector, which includes the above-mentioned high-current contact terminal. Specifically, since the high-voltage connector uses the above-mentioned high-current contact terminal, more contact points with the male terminal are formed on the high-current contact terminal, so that the contact area with the male terminal is larger, the contact resistance generated is smaller, and the heat generated during long-term transmission is less, the ability to pass current is enhanced, and the current carrying capacity is enhanced; and the multiple first elastic sheets 121 and the multiple second elastic sheets 221 respectively correspond to each other and elastically clamp the male terminal, thereby increasing the pressure of the high-voltage connector on the male terminal and maintaining better clamping stability.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
