[0030] The following refers to Figure 1 - Figure 2 Describe the terminal box structure 100 according to an embodiment of the present utility model. The terminal box structure 100 can reduce the terminal manufacturing cost, improve the assembly efficiency, reduce the contact resistance, increase the reliability of the electrical connection, and has a simple and compact structure, small occupied space, high reliability, and wide application range.
[0031] As Figure 1 - Figure 2 As shown, the terminal box structure 100 according to an embodiment of the present utility model includes: a box body 1, an internal terminal 2, and a power terminal 3.
[0032] An installation cavity 13 is formed inside the box body 1, that is, the inside of the box body 1 is hollow to form the installation cavity 13, which is used to accommodate and protect relevant electrical connection components, prevent damage and erosion to the internal terminal 2 and the like by dust, moisture and other external foreign matters, thereby ensuring the stability and safety of the electrical connection. At the same time, it can also reduce the interference between various electrical components, thereby improving the reliability of the electrical connection.
[0033] The internal terminal 2 is an intermediary for electrical connection, and electrical signals or electrical energy can be transmitted through the internal terminal 2. Among them, the internal terminal 2 is located inside the installation cavity 13, that is, the internal terminal 2 is installed inside the box body 1 to protect and support the internal terminal 2.
[0034] The internal terminal 2 includes a first terminal plate 21 and a second terminal plate 22 formed integrally. The first terminal plate 21 is provided with a first connection portion. The second terminal plate 22 includes a plurality of spaced-apart wire-passing portions 221. That is, the second terminal plate 22 can include two, three or even more spaced-apart wire-passing portions 221. Each wire-passing portion 221 is used for passing through a connection wire harness, so that a plurality of connection wire harnesses can be connected through the plurality of wire-passing portions 221 to improve the reliability of the electrical connection. The spaced-apart distribution can avoid interference between the connection wire harnesses.
[0035] Specifically, by integrally forming the first terminal plate 21 and the second terminal plate 22 into an integral built-in terminal 2, the number of components can be reduced, the structural size can be decreased, thereby reducing the terminal manufacturing cost, improving the assembly efficiency, and reducing the contact resistance, increasing the reliability of the electrical connection. In practice, the first terminal plate 21 and the second terminal plate 22 can be integrally formed by stamping. Among them, the first connection portion provided on the first terminal plate 21 is used to connect with the power terminal 3, and the wire threading portion 221 provided on the second terminal plate 22 is used to thread the connection wire harness. That is, the second terminal plate 22 can provide multiple electrical connection points, so that the connection wire harness can be safely and orderly connected into the box body 1 and connected to the power terminal 3 through the first connection portion of the first terminal plate 21 to achieve a reliable electrical connection. Moreover, the multiple connection wire harnesses are distributed in the box body 1 at intervals, which can reduce the terminal contact resistance, facilitate heat dissipation, and avoid heat accumulation during the conduction process of the terminal, resulting in a fire risk.
[0036] Furthermore, the power terminal 3 is located outside the installation cavity 13, and the power terminal 3 is provided with a second connection portion, and the second connection portion is connected to the first connection portion.
[0037] Specifically, the power terminal 3 can be connected to an external power supply or other electrical structures conveniently and reliably. The power terminal 3 is provided with a second connection portion, and the second connection portion is connected to the first connection portion. That is, the connection between the power terminal 3 and the built-in terminal 2 can be achieved through the second connection portion, and then the electrical connection from the external power supply to the electrical components in the box body 1 can be realized, ensuring the smooth transmission of electrical signals.
[0038] According to the terminal box structure 100 of the embodiment of the present invention, by integrally forming the built-in terminal 2, the terminal manufacturing cost can be reduced, the assembly efficiency can be improved, the contact resistance can be reduced, and the reliability of the electrical connection can be increased. The power terminal 3 is connected to the built-in terminal 2 through the second connection portion and the first connection portion to form an integral terminal, so as to achieve a reliable electrical connection, ensure the smooth transmission of electrical signals, and has a simple and compact structure, small occupied space, high reliability, and wide application range.
[0039] In some embodiments, the terminal box structure 100 further includes a connection nut 4. The box body 1 is provided with an avoidance hole. The first connection portion is configured as a connection hole, and the second connection portion is configured as a connection post 31. Among them, the connection post 31 sequentially passes through the avoidance hole and the connection hole and is threadedly connected to the connection nut 4 in the installation cavity 13.
[0040] Specifically, as Figure 2 shown, the first connection portion is configured as a connection hole, and the second connection portion is configured as a connection post 31. The terminal box structure 100 is provided with a connection nut 4, and the connection nut 4 is used to fixedly connect the second connection portion, that is, the connection post 31. As Figure 1In the left - right direction shown, an avoidance hole may be provided on the right - hand side of the box body 1. The avoidance hole is used to avoid the connecting column 31, so that the connecting column 31 can pass through the box body 1 smoothly and enter the installation cavity 13 to be connected with the connecting nut 4, thereby realizing the connection between the power terminal 3 and the second terminal board 22. Among them, the shape and size of the connection hole are adapted to the shape and size of the connecting column 31. The avoidance hole should be at least larger than the size of the connecting column 31 to ensure that the connecting column 31 can enter the installation cavity 13 without hindrance. Thus, the connecting column 31 can sequentially penetrate through the avoidance hole and the connection hole from outside to inside, extend into the installation cavity 13 and be threadedly connected with the connecting nut 4. Thereby, a tight and reliable connection between the power terminal 3 and the built - in terminal 2 is realized, improving the stability and reliability of the electrical connection, and facilitating installation and disassembly.
[0041] In some embodiments, the power terminal 3 further forms a limiting portion 32. The limiting portion 32 is in limiting cooperation with the box body 1, and the limiting portion 32 is used to limit the rotation of the power terminal 3 relative to the axis of the connecting column 31.
[0042] That is to say, through the limiting cooperation between the limiting portion 32 and the box body 1, the rotation of the power terminal 3 relative to itself can be prevented, ensuring the connection stability of the power terminal 3, and preventing situations such as connection loosening and poor contact of the power terminal 3 from occurring, thereby improving the reliability and stability of the electrical connection. At the same time, the limiting cooperation between the limiting portion 32 and the box body 1 is also conducive to achieving precise positioning of the power terminal 3. That is, when installing the power terminal 3, the limiting portion 32 can guide the power terminal 3 to move to the correct installation position, improving the installation efficiency. And the limiting portion 32 can protect the power terminal 3, enhancing the structural strength of the power terminal 3 and avoiding the occurrence of a fire caused by damage to the power terminal 3 when it is side - hit.
[0043] Specifically, as Figure 2 shown, the power terminal 3 is provided with a limiting portion 32. The limiting portion 32 is on the side of the power terminal 3 close to the connection with the box body 1. In actual installation, the limiting portion 32 can prevent the power terminal 3 from rotating when tightening the connecting column 31 and the connecting nut 4, and the limiting portion 32 is in limiting contact with the side of the box body 1, which can improve the connection strength between the power terminal 3 and the box body 1, ensure the installation stability of the power terminal 3, and prevent its axial movement in the left - right direction as Figure 1 shown.
[0044] In some embodiments, as Figure 2As shown, the connecting nut 4 is also formed with an annular flange 41 extending radially outward. In actual installation, after the connecting nut 4 is tightened, the annular flange 41 abuts against the first terminal plate 21. Thus, by providing the annular flange 41, the contact area between the connecting nut 4 and the first terminal plate 21 can be increased, and the contact resistance can be reduced. Through the close fit of the annular flange 41 and the first terminal plate 21, the connection stability between the connecting nut 4 and the connecting post 31 can also be improved, preventing the connecting nut 4 from loosening, thereby further enhancing the connection reliability and stability between the first terminal plate 21 and the power terminal 3. And when the connecting nut 4 is tightened, the annular flange 41 can reduce the dispersed stress and the risk of damage to the connecting nut 4.
[0045] Meanwhile, during actual installation, when the power terminal 3 is connected to an external power source, by providing the connecting nut 4 with an annular flange 41, it is convenient for the operator to pre-hang the terminal box structure 100 with one hand and then pre-tighten the nut, enabling one person to complete the installation, thus improving the assembly convenience.
[0046] In some embodiments, an operation slot 14 is formed between at least two wire-passing portions 221. The operation slot 14 is for an operation tool to pass through to pre-tighten the connecting nut 4. The operation slot 14 is arranged to open towards the outside of the box body 1. The operation slot 14 and the connecting nut 4 are distributed opposite to each other along the opening direction of the operation slot 14. Thus, the operation tool can enter the accommodation installation cavity 13 from outside the box body 1 and pre-tighten the connecting nut 4 in the operation slot 14, improving the installation convenience and safety.
[0047] Specifically, as Figure 2 shown, the built-in terminal 2 is provided with two wire-passing portions 221, and the two wire-passing portions 221 are spaced apart from each other in the up-down direction by a certain distance, reserving space for the operation slot 14. The two wire-passing portions 221 can pass through two connecting wire harnesses, increasing the number of connecting wire harnesses. Among them, the upper and lower side walls of the operation slot 14 can support and fix the two wire-passing portions 221. The structural shape and size of the operation slot 14 should be adapted to the operation tool, so as to accommodate the operation tool, facilitating the operator to operate with the operation tool, which is flexible and convenient. In actual design, the operation slot 14 can be constructed as a U-shaped slot, a square slot, a V-shaped slot, a concave-convex arc slot or any other shape of slot as long as the operation tool can pass through smoothly, not limited to the shape shown in the figure.
[0048] In some embodiments, the second terminal plate 22 further includes a reinforcing flange portion 222. The reinforcing flange portion 222 is bent and connected to the first terminal plate 21. A plurality of wire-passing portions 221 are spaced apart and connected to the side of the reinforcing flange portion 222 away from the first terminal plate 21.
[0049] Specifically, setting the reinforcing flanging portion 222 can improve the overall structural strength of the second terminal plate 22, enabling it to withstand a large load. By bending and connecting the reinforcing flanging portion 222 to the first terminal plate 21, a tight connection can be achieved between the reinforcing flanging portion 222 and the second terminal plate 22, thereby enhancing the connection strength between the first terminal plate 21 and the second terminal plate 22, ensuring connection reliability, reducing the conductive resistance of the built-in terminal 2, and enabling multiple wire-passing portions 221 to be spaced apart and connected to the side of the reinforcing flanging portion away from the first terminal plate 21, which can improve the structural strength of the wire-passing portions 221 and ensure the stability of the wire-passing portions 221.
[0050] In actual design, an overall vertical flanging can be set to increase the structural strength of the built-in terminal 2, prevent the first terminal plate 21 from deforming when tightening the connection nut 4, which affects the structural stability, and at the same time, reduce the conductive resistance of the built-in terminal 2.
[0051] In some embodiments, the first terminal plate 21 and the second terminal plate 22 are bent and connected. The bent connection can improve the connection strength between the first terminal plate 21 and the second terminal plate 22. The box body 1 has a connected first inner wall 15 and second inner wall 16. The first terminal plate 21 is attached to the first inner wall 15, and the second terminal plate 22 is attached to and connected to the second inner wall 16. In this way, by tightly attaching and connecting the two sub-plates to the two inner walls of the box body 1 respectively, the voids inside the box body 1 can be reduced, the space inside the box body 1 can be fully utilized, the compactness of the terminal box structure 100 can be improved, which is beneficial to the heat dissipation of the built-in terminal 2 and prevents heat accumulation.
[0052] Specifically, as Figure 2 shown, the box body 1 can be constructed as a rectangular structure. The box body 1 is provided with a connected first inner wall 15 and second inner wall 16. As Figure 1 shown in the direction, the first inner wall 15 is the right inner wall, and the second inner wall 16 is the rear inner wall. Among them, the first terminal plate 21 and the second terminal plate 22 are set to be bent and connected to adapt to the shapes of the first inner wall 15 and the second inner wall 16, so as to achieve a tight fit and connection between the first terminal plate 21 and the first inner wall 15, and a tight fit and connection between the second terminal plate 22 and the second inner wall 16. Furthermore, the voids between the terminal plate and the inner wall can be reduced, the installation stability of the built-in terminal 2 can be improved, and it is beneficial to the heat dissipation of the built-in terminal 2.
[0053] In some embodiments, the wire-passing portion 221 includes two relatively distributed wire-passing flanges 2211. A wire-passing groove 2212 is formed between the two wire-passing flanges 2211. The connecting wire harness is adapted to extend into the wire-passing groove 2212, and the wire-passing flanges 2211 are adapted to press the connecting wire harness.
[0054] Specifically, as Figure 2As shown, the built-in terminal 2 is provided with a wire threading part 221. The wire threading part 221 includes two wire threading flanges 2211 distributed oppositely in the up-and-down direction shown in the figure. A wire threading groove 2212 is formed between the two wire threading flanges 2211. The wire threading groove 2212 is used for the connection wire harness to pass through. Among them, the shape and size of the wire threading groove 2212 should be adapted to the connection wire harness to accommodate the thickness of the connection wire harness. In this way, when the connection wire harness extends into the wire threading groove 2212, the wire threading flanges 2211 can press the connection wire harness tightly, support and fix the connection wire harness, ensure the installation stability of the connection wire harness, prevent it from loosening or falling off, and can reduce the resistance.
[0055] In some embodiments, the box body 1 includes a lower box 11 and an upper cover 12. The upper cover 12 is connected to the lower box 11 to define an installation cavity 13. The built-in terminal 2 is installed in the lower box 11.
[0056] Specifically, as Figure 1 shown, the box body 1 includes a lower box 11 and an upper cover 12. In the front-back direction shown in the figure, the lower box 11 is located at the rear and the upper box is located at the front. The shapes and sizes of the lower box 11 and the upper cover 12 are adapted to each other. The left side and the front side of the lower box 11 are open to facilitate the installation of the built-in terminal 2 and the connection of the power supply terminal 3. The upper cover 12 is open backward to facilitate the upper cover 12 to be covered on the lower box 11. A protruding cover plate 123 is provided in the middle of the left side of the upper cover 12. In this way, after the upper cover 12 is covered on the lower box 11, the operation groove 14 can be covered. At the same time, two wire threading holes 17 for the connection wire harness to pass through are left in the upper and lower parts of the left side of the box body 1.
[0057] Among them, the upper cover 12 has a first side 121 and a second side 122 distributed oppositely. The first side 121 is rotatably connected to the lower box 11, that is, the first side 121 can rotate relative to the lower box 11 by a certain angle. Thus, through the relative rotation of the first side 121 and the lower box 11, the upper cover 12 can be easily opened and closed relative to the lower box 11, so as to facilitate the installation and disassembly of the components in the installation cavity 13. The second side 122 is snap-connected to the lower box 11, that is, corresponding snap structures such as snaps and slots, hooks or holes can be provided on the second side 122 or the lower box 11. Through the snap structure, the upper cover 12 and the lower box 11 are tightly connected, that is, the upper cover 12 can be covered on the lower box 11 to realize the sealing of the terminal box structure 100 and ensure the connection stability and reliability of the upper cover 12 and the lower box 11.
[0058] Specifically, as Figure 1 and Figure 2As shown, the upper cover 12 has a first side 121 and a second side 122 that are relatively distributed. In the up-and-down direction shown in the figure, the first side 121 is the lower side, and the second side 122 is the upper side. A rotating shaft is provided on the first side 121, and a card slot is provided on the second side 122. Corresponding card slots and rotating shaft fixing structures are provided on the upper side and the lower side of the lower box 11. Thus, the first side 121 is rotatably connected to the lower box 11, and the second side 122 is snap-connected to the lower box 11, thereby realizing the opening and closing of the box body 1.
[0059] In actual installation, through snap connection, when the box body 1 is not fastened tightly, it is also easy to be discovered by the operator, improving the safety of the terminal box structure 100 and facilitating assembly.
[0060] The present utility model also proposes a vehicle.
[0061] The vehicle according to an embodiment of the present utility model is provided with the terminal box structure 100 of any one of the above embodiments.
[0062] Among them, the integral terminal box structure 100 can reduce the thickness of the built-in terminal 2 in the up-and-down direction, and the overall structure of the terminal box structure 100 is relatively small, which is conducive to the layout of the terminal box structure 100 on the vehicle, reducing the installation space of the terminal box structure 100 on the vehicle, facilitating the improvement of the compactness of the vehicle, and to a certain extent reducing the cost, facilitating the realization of platformization of the terminal box structure 100 and making its application range wider.
