[0043] Figure 1 It is a schematic diagram of the three-dimensional structure of the wire connector according to an embodiment of the present invention. Figure 2 and Figure 3 They are respectively a schematic diagram of the connection relationship of the sheath, the first terminal and the elastic contact member and a schematic diagram of the explosion structure of the embodiment of the present invention. Figure 1-Figure 3 As shown, the wire connector of the embodiment of the present invention includes a sheath 1 and at least one first terminal 2. The sheath 1 has a receiving cavity 11, and a first opening 12 and a second opening 13 communicating with the receiving cavity 11. The first opening 12 is arranged along a first direction DIR1, and the second opening 13 is arranged along a second direction DIR2, wherein the first direction DIR1 intersects the second direction DIR2. The first terminal 2 is fixedly connected to the sheath 1 and includes a first cable connecting portion 21 and a first terminal contact portion 22. The first cable connecting portion 21 is used to connect to the first wire 6, and the first terminal contact portion 22 extends from the first opening 12 into the receiving cavity 11.

[0044] The wire connector further includes a second terminal 3 corresponding to the first terminal 2. The second terminal 3 includes a second cable connection portion 31 for connecting to a second wire and a second terminal contact portion 32 for electrically connecting to the first terminal 2. The second terminal contact portion 32 can enter the accommodation cavity 11 from the second opening 13 and be electrically connected to the first terminal contact portion 22. The first terminal contact portion 22 and the second terminal contact portion 32 can be substantially formed in a flat plate shape, which can increase the contact area between the first terminal 2 and the second terminal 3 and improve the current-carrying capacity of the wire connector. The first cable connection portion 21 and the second cable connection portion 31 can also be substantially in a flat plate shape. Electrical connection between the first cable connection portion 21 and the first wire 6 and between the second cable connection portion 31 and the second wire can be achieved by means such as crimping and ultrasonic welding. The first terminal 2 and the second terminal 3 can be manufactured by stamping, which can improve production efficiency.

[0045] Figure 4 is a schematic three-dimensional structure diagram of the sheath according to an embodiment of the present invention. As Figures 1-4 shown, the first opening 12 of the sheath 1 is provided along the first direction DIR1, and the second opening 13 is provided along the second direction DIR2, where the first direction DIR1 intersects the second direction DIR2, preventing interference from other terminals when some of the terminals are inserted or removed, and facilitating electrical connection between wires extending in different directions, and can be used in a narrow space. Optionally, the first direction DIR1 and the second direction DIR2 are perpendicular to each other.

[0046] Optionally, the sheath 1 may further have a fourth opening, and the fourth opening is opposite to the second opening 13, that is, the sheath 1 is completely penetrated in the second direction DIR2. Thus, the second terminal contact portion 32 can also enter the accommodation cavity 11 from the fourth opening to be electrically connected to the first terminal 2.

[0047] Figure 5 is a schematic three-dimensional structure diagram of the elastic contact member according to an embodiment of the present invention. As Figure 5 shown, to enable good contact between the first terminal 2 and the second terminal 3 to ensure the stability of electrical connection, the wire connector may further include at least one elastic contact member 4. The elastic contact member 4 is disposed in the accommodation cavity 11, forming at least one first cavity 41 and a third opening 42 communicating with the first cavity 41. The third opening 42 corresponds to the second opening 13, and the second terminal contact portion 32 can enter the first cavity 41 from the third opening 42.

[0048] As Figure 2 , Figure 3 and Figure 5 shown, the elastic contact member 4 can be a structure with a cross-section approximately in the shape of a "匚" formed by substantially three surfaces, and the three surfaces include a top surface, a bottom surface, and a side surface, and the side surface can be perpendicular to the top surface and the bottom surface.

[0049] The elastic contact member 4 may be provided with multiple contact springs 45, which are arranged in parallel and with their central portions protruding toward the first cavity 41. The contact springs 45 are used to contact the second terminal contact portion 32. The contact springs 45 may be provided on the top and bottom surfaces of the elastic contact member 4. The elastic contact member 4 is made of a conductive material. Because the contact springs 45 have a certain degree of elasticity, when the second terminal 3 enters the first cavity 41, the contact springs 45 can press against the second terminal 3. As a result, the elastic contact member 4 can conduct electricity between the first terminal 2 and the second terminal 3 in contact therewith, and can also relatively fix the second terminal 3, to a certain extent, preventing the second terminal 3 from loosening and shifting, thereby increasing the conductive area between the first terminal 2 and the second terminal 3. The provision of the elastic contact member 4 can also reduce wear on the terminal surface, extending the life of the first terminal 2 and the second terminal 3. The contact springs 45 can be formed by cutting multiple parallel grooves in the elastic contact member 4 and then using stamping or bending.

[0050] The sheath 1 may include a top plate 15 and a bottom plate 16 disposed opposite each other, and a first side wall 17 connecting one end of the top plate 15 and one end of the bottom plate 16. The first opening 12 and the first side wall 17 are disposed opposite each other. Optionally, the first side wall 17 is substantially perpendicular to the top plate 15 and the bottom plate 16. The sheath 1 may be integrally formed using methods such as injection molding and stamping, which simplifies assembly steps and ensures the overall structural strength of the sheath 1.

[0051] Figure 6 FIG is a schematic diagram of the three-dimensional structure of the first terminal of an embodiment of the present invention. Figures 1-4 as well as Figure 6 As shown, a connecting ear 19 can be provided at the first opening 12 on the sheath 1. The connecting ear 19 extends from the first opening 12 in a direction away from the accommodating cavity 11. The first terminal 2 and the connecting ear 19 can be connected by a fixing member 5 to fix the first terminal 2 and the sheath 1 to each other. For example, the connecting ear 19 and the first terminal 2 have corresponding connecting holes. The fixing member 5 can be a bolt or a pin. The connecting ear 19 and the first terminal 2 can be fixedly connected by passing the bolt or pin through the connecting hole on the connecting ear 19 and the first terminal 2. Preferably, the connecting ear 19 and the first terminal 2 can be connected by two or more fixing members 5 to prevent the first terminal 2 and the sheath 1 from rotating relative to each other due to only one fixing member 5.

[0052] There may be a positioning hole 171 on the first side wall 17 of the sheath 1, and the first terminal contact portion 22 has a protruding positioning block 221 corresponding to the positioning hole 171 at one end facing the first side wall 17. The cooperation between the positioning hole 171 and the positioning block 221 can prevent the first terminal 2 from shaking.

[0053] In an optional embodiment, the wire connector has two elastic contacts 4. After the first terminal contact portion 22 enters the accommodating cavity 11 from the first opening 12, it divides the accommodating cavity 11 into two spaces. The two elastic contacts 4 are respectively disposed in the two spaces on either side of the first terminal 2, that is, the first terminal 2 is disposed between the two elastic contacts 4. Accordingly, the wire connector may include two second terminals 3, and the second terminal contact portions 32 of the two second terminals 3 are respectively disposed in the first cavities 41 of the two elastic contacts 4, that is, the first terminal contact portion 22 is located between the two second terminals 3 and the two elastic contacts 4. Of course, the two elastic contacts 4 can also be stacked on the same side of the first terminal 2, that is, the two elastic contacts 4 are in contact with each other, and the two second terminals 3 are electrically connected to each other and to the first terminal 2 through the elastic contacts 4.

[0054] In another optional embodiment, the wire connector has a resilient contact member 4, the top surface of which contacts the top plate 15 of the sheath 1, and the bottom surface of which contacts the bottom plate 16 of the sheath 1. The first terminal contact portion 22 and the second terminal contact portion 32 are both disposed within the first cavity 41 of the resilient contact member 4. Optionally, the first terminal contact portion 22 is disposed in the middle of the accommodating cavity 11, dividing the accommodating cavity 11 into two spaces. The two second terminal contact portions 32 are respectively disposed in the two spaces and are electrically connected to the first terminal contact portion 22, thereby increasing the contact area between the terminals.

[0055] Of course, those skilled in the art should understand that, under the premise that the overload capacity can meet the requirements, the wire connector can also be electrically connected to the first terminal 2 using only one second terminal 3 .

[0056] To increase the current carrying capacity of the wire connector, a bend 33 is provided between the second cable connection portion 31 and the second terminal contact portion 32 of the second terminal 3. Thus, the two second terminals 3 can be fixedly connected to the second wire via the second cable connection portion 31. The two second terminal contact portions 32 can be inserted into the first cavity 41 from either side of the first terminal contact portion 22 and electrically connected to the first terminal 2. This increases the effective conductive area between the first wire 6 and the second wire, thereby increasing the overload capacity of the wire connector. To ensure that the second terminal contact portion 32 and the first terminal contact portion 22 are parallel, allowing for smooth insertion and removal of the second terminal 3 and forming a stable connection with the first terminal 2, the distance between the second terminal contact portions 32 of the two second terminals 3 should be no less than the thickness of the first terminal contact portion 22. Preferably, the distance between the second terminal contact portions 32 of the two second terminals 3 is consistent with the distance between the two first cavities 41 or the distance between the two spaces formed by a first cavity 41 separated by the first terminal 2.

[0057] The elastic contact member 4 may be provided with at least one retaining spring 43, and the sheath 1 may have a corresponding retaining groove 14. The retaining spring 43 is bent toward the retaining groove 14 and extends toward the second opening 13. Due to the elasticity of the retaining spring 43, the elastic contact member 4 can be smoothly placed into the accommodating cavity 11 through the second opening 13. When the elastic contact member 4 moves to the retaining groove 14, the retaining spring 43 returns to its original shape due to the increased accommodating space. The retaining groove 14 prevents the retaining spring 43 from exiting the retaining groove 14 toward the second opening 13, thereby preventing the elastic contact member 4 from exiting the second opening 13. When the elastic contact piece 4 needs to be removed from the second opening 13, a tool can be used to extend into the anti-retraction groove 14 to press the anti-retraction spring piece 43 so that the anti-retraction spring piece 43 bends toward the first cavity 41, or the top and bottom surfaces of the elastic contact piece 4 can be squeezed to make the anti-retraction spring piece 43 withdraw from the anti-retraction groove 14, and the elastic contact piece 4 can smoothly withdraw from the accommodating cavity 11 from the second opening 13.

[0058] Preferably, the top plate 15 and the bottom plate 16 of the sheath 1 both have a stop groove 14, and a corresponding stop groove 23 can also be provided on the first terminal 2. The top and bottom surfaces of the elastic contact member 4 are both provided with a stop spring 43, thereby better realizing the stop function and preventing the elastic contact member 4 from moving when the second terminal 3 is pulled out.

[0059] In order to better position the elastic contact 4, the elastic contact 4 can also have a limiting piece 44. The limiting piece 44 is arranged at the third opening 42 of the elastic contact 4. The limiting piece 44 can be perpendicular to the top plate 15 and the bottom plate 16 of the sheath 1. Preferably, the limiting piece 44 is provided on the edges of the top and bottom surfaces of the elastic contact 4. Thus, when the elastic contact 4 is pushed into the predetermined position from the second opening 13, the limiting piece 44 contacts the side of the top plate 15, the bottom plate 16 and / or the first terminal contact portion 22, thereby limiting the position of the elastic contact 4 and preventing the elastic contact 4 from entering the accommodating cavity 11 too deeply and being difficult to remove. The stop spring 43 cooperates with the stop grooves 14, 23 and the limiting piece 44 to prevent the elastic contact 4 from moving when the second terminal 3 is inserted or removed.

[0060] The top plate 15 and bottom plate 16 of the sheath 1 may also include stopper protrusions 18 to prevent movement of the second terminal 3. The stopper protrusions 18 project toward the accommodating cavity 11, deforming the elastic contact member 4. This clamps the second terminal 3 and prevents its movement, securing it relative to the first terminal 2 and achieving a stable electrical connection. This allows for high-current and high-voltage power transmission while preventing the second terminal 3 from frequently moving and generating sparks, which could be dangerous. Preferably, a corresponding stopper protrusion 222 may also be provided on the first terminal contact portion 22.

[0061] When at least one limiting piece 44 is opposite to the side surface of the first terminal contact portion 22, a protruding stopper 223 may be further provided on the side surface of the first terminal contact portion 22. The stopper 223 may be provided near the first side wall 17. The stopper 223 cooperates with the limiting piece 44 to limit the relative position between the elastic contact member 4 and the first terminal 2, thereby preventing the elastic contact piece from undergoing significant displacement.

[0062] In order to reduce costs and improve interchangeability between components, the second terminal 3 and the first terminal 2 can be manufactured in exactly the same shape.

[0063] The wire connectors according to embodiments of the present invention can be widely used in a variety of applications, such as connecting power devices and connecting large electrical equipment to power sources. Those skilled in the art can apply the wire connectors to specific devices based on actual needs and common knowledge in the art, and a detailed description thereof will not be given here.

[0064] A wire connector provided in an embodiment of the present invention includes a sheath 1 and at least one first terminal 2. The sheath 1 has a receiving cavity 11. By providing a first opening 12 and a second opening 13 on the sheath 1 that intersect with the communication direction of the receiving cavity 11, the first terminal 2 is fixedly connected to the sheath 1 and the first terminal contact portion 22 is extended from the first opening 12 into the receiving cavity 11 of the sheath 1. This can achieve a stable connection between the terminals, increase the effective flow area, improve the load-bearing capacity of the wire connector, and enable connection between the terminals at a certain angle.

[0065] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
