Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle component technology, and more particularly to a terminal block and a vehicle. Background Technology
[0002] Vehicles are equipped with various electrical components with different characteristics. As these components become more diverse, the requirements for vehicle wiring harnesses are becoming increasingly stringent. Terminal blocks serve to connect wires. However, in related technologies, terminal blocks are susceptible to corrosion from external moisture after being connected to wires, which can easily lead to electrolytic corrosion at the connection between the terminal block and the wire. Utility Model Content
[0003] This application provides a terminal block and a vehicle, which aims to improve the problem of electro-corrosion at the connection between the terminal block and the wire.
[0004] According to an embodiment of this application, the terminal block includes a crimping portion and a sealant. The crimping portion is pressed against the outer surface of a conductor. The crimping portion has a piercing area and a sealant application area. The piercing area has a piercing element adapted to pierce the oxide layer of the conductor. The sealant is disposed in the sealant application area. When the crimping portion is pressed against the outer surface of the conductor, the sealant is adapted to be pressed towards the piercing area to seal the gap between the crimping portion and the conductor at the piercing element.
[0005] According to the embodiments of this application, the terminal block with a piercing element provided in the crimping part can effectively pierce the oxide layer of the wire, so that the terminal block can be better electrically connected to the wire. In addition, the sealant can effectively seal the crimping part at the piercing element and the wire, so that the crimping part and the wire are not easily corroded by moisture, and thus are not prone to electro-corrosion. Moreover, this application can achieve the connection between the terminal block and the wire with one compression, and can also achieve the sealing of the crimping part at the piercing element and the wire, which can simplify the processing technology, reduce the assembly difficulty, and improve the assembly efficiency.
[0006] In some embodiments of this application, the sealant includes an anti-corrosion adhesive.
[0007] In the above example, the glue can flow well to the gap between the crimped part and the wire, thus filling the gap well, and can also seal the crimped part and the wire at the puncture point well, resulting in a good sealing effect.
[0008] In some embodiments of this application, the adhesive application area is provided with an adhesive groove, and at least a portion of the sealant is disposed within the adhesive groove.
[0009] In the above example, by setting up a glue groove, the difficulty of sealant placement can be reduced, and the amount of glue applied can be increased. At the same time, after the sealant is placed in the glue groove, it can also be better limited, so that the punctured area can be reliably sealed after the crimped part is squeezed.
[0010] In some embodiments of this application, two adhesive grooves are provided along the first direction, and the two adhesive grooves are respectively located on both sides of the puncture area.
[0011] In the above example, increasing the number of adhesive grooves increases the amount of sealant, allowing more sealant to be applied towards the puncture area, thus improving the sealing effect. Furthermore, placing two adhesive grooves on either side of the puncture area allows the sealant stored in both grooves to effectively seal the central puncture area under pressure, further enhancing the sealing performance.
[0012] In some embodiments of this application, the glue groove is formed by stamping the crimping portion.
[0013] In the above example, the glue groove, which is the crimping part of the metal part, can be constructed by stamping. The operation is simple and convenient, and the shape of the glue groove can be quite flexible.
[0014] In some embodiments of this application, along the second direction, the width of the adhesive groove is greater than or equal to the width of the puncture area.
[0015] In the example above, the design of the width of the glue groove and the width of the puncture area can help the sealant in the glue groove to better seal the puncture area, resulting in a good sealing effect and high reliability.
[0016] In some embodiments of this application, the puncturing element includes a protrusion, and multiple protrusions are provided, with the multiple protrusions arranged at intervals.
[0017] In the above example, by setting convex hulls and having multiple convex hulls, the oxide layer can be pierced more effectively, and the crimped part and the wire can be electrically connected more effectively.
[0018] In some embodiments of this application, the plurality of the convex hulls are arranged in a deterministic manner.
[0019] In the example above, the row-and-column arrangement of the protrusions makes the arrangement of the protrusions more orderly, which can help increase the number of protrusions, thereby increasing the contact area between the crimping part and the wire, thus enhancing the electrical connection between the crimping part and the wire. In addition, the orderly arrangement of the protrusions also helps the sealant to better surround the outer periphery of the protrusions when squeezed towards the puncture area, thereby better sealing the crimping part and the wire at the protrusion and improving the sealing effect.
[0020] In some embodiments of this application, the terminal block further includes a plug portion and a transition connection portion, the transition connection portion being connected between the plug portion and the crimp portion, and the width of the transition connection portion being smaller than the width of the crimp portion along a second direction.
[0021] In the example above, by increasing the width of the crimping part, the contact area with the wire can be increased, which is beneficial to the connection between the crimping part and the wire.
[0022] This application also proposes a vehicle having the wiring terminals described in the above embodiments.
[0023] According to the vehicle of the present application embodiment, by providing the wiring terminals of the above embodiment, when the wiring is connected, it can not only connect the wiring terminals and the wires by simply pressing them together, but also seal the wiring terminals and the wires. This can reduce the number of steps in the wiring connection process of the vehicle, thereby improving the assembly efficiency of the vehicle, reducing electrical corrosion in the vehicle's wiring, and improving the stability of the wiring inside the vehicle.

[0035] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0036] Vehicles are equipped with various electrical components with different characteristics. These diverse components place increasingly stringent requirements on vehicle wiring harnesses. Terminal blocks serve to connect wires; however, in related technologies, terminal blocks are susceptible to corrosion from external moisture after connection, leading to electrolytic corrosion at the connection point. Often, an additional sealing process is added after the terminal block is connected to the wire, which not only increases workload but also results in unsatisfactory sealing performance, potentially leading to seal failure.
[0037] This application provides a terminal block 100, which includes a crimping part 1 and a sealant 4. The crimping part 1 is pressed against the outer surface of a wire 200. The crimping part 1 has a piercing area 11 and a coating area 12. The piercing area 11 has a piercing element 111, which is adapted to pierce the oxide layer of the wire 200. The sealant 4 is disposed in the coating area 12. When the crimping part 1 is pressed against the outer surface of the wire 200, the sealant 4 is adapted to be pressed towards the piercing area 11 to seal the gap between the crimping part 1 at the piercing element 111 and the wire 200.
[0038] In other words, when the terminal 100 is connected to the wire 200, the wire 200 can be placed on the crimping part 1, and then the crimping part 1 can be clamped by the tooling to deform the crimping part 1, thereby making the crimping part 1 wrap around the outer surface of the wire 200, thus realizing the connection between the terminal 100 and the wire 200. In this process, the piercing part 111 can pierce the oxide layer of the wire 200 under the action of the clamping force, so that the wire 200 can be electrically connected to the terminal 100 better.
[0039] During the process of piercing the oxide layer, the piercing element 111 gradually penetrates into the wire 200, causing deformation of the outer surface of the wire 200 and piercing the oxide layer. During this process, a large gap exists between the wire 200 and the crimping part 1 due to the piercing element 111. This gap makes it easy for moisture to enter the connection between the crimping part 1 and the wire 200, potentially leading to electrolytic corrosion. This application addresses this by using sealant 4 to tighten the crimping part 1... During the process of wrapping the outer surface of the wire 200, the sealant 4 can be pressed towards the puncture area 11. That is, under the action of pressure, the sealant 4 will be squeezed towards the area with larger gaps, which means it is easier to squeeze towards the gaps. After the sealant 4 is squeezed into the gaps, it can better seal the crimped part 1 at the puncture part 111 and the wire 200. In other words, the sealant 4 can better fill the gap between the crimped part 1 at the puncture part 111 and the wire 200, making it less susceptible to water vapor erosion between the crimped part 1 and the wire 200, and thus less prone to electrolytic corrosion.
[0040] Furthermore, during the connection process between the terminal 100 and the wire 200, the piercing element 111 can pierce the oxide layer. Simultaneously, under the action of clamping force, the sealant 4 is pressed towards the pierced area 11 to seal the crimped portion 1 at the piercing element 111 and the wire 200. The entire process is completed in one step, with a simple processing method and fewer steps. Compared with related technologies, which require additional steps such as applying adhesive after the terminal 100 and the wire 200 are connected, this application can achieve the connection between the terminal 100 and the wire 200 and seal the crimped portion 1 at the piercing element 111 and the wire 200 in one clamping operation. This simplifies the processing technology, reduces assembly difficulty, and improves assembly efficiency.
[0041] Therefore, according to the embodiment of the present invention, the terminal 100 can effectively pierce the oxide layer of the wire 200 by providing a piercing element 111 in the crimping part 1, so that the terminal 100 can be better electrically connected to the wire 200. In addition, the sealant 4 can effectively seal the crimping part 1 at the piercing element 111 and the wire 200, so that the crimping part 1 and the wire 200 are not easily corroded by moisture, and thus are not prone to electro-corrosion. Moreover, the present application can achieve the connection between the terminal 100 and the wire 200 by one crimping, and can also achieve the sealing of the crimping part 1 at the piercing element 111 and the wire 200, which can simplify the processing technology, reduce the assembly difficulty, and improve the assembly efficiency.
[0042] For example, the conductor 200 can be a copper conductor 200 or an aluminum conductor 200, and this application does not impose any restrictions.
[0043] In some embodiments of this utility model, the sealant 4 includes an anti-corrosion adhesive.
[0044] In other words, adhesive can be applied to the surface of the crimping part 1. When subjected to pressure, the adhesive can flow more easily toward the gap between the crimping part 1 and the wire 200, thereby filling the gap better and sealing the crimping part 1 and the wire 200 at the puncture part 111 better, resulting in a good sealing effect.
[0045] For example, the adhesive can be a corrosion-resistant adhesive, thereby ensuring that it is not prone to failure after sealing and has good reliability. Furthermore, it is understood that the adhesive can also be an adhesive with other functions, and this application does not impose any limitations.
[0046] In the above example, the glue can flow well to the gap between the crimping part 1 and the wire 200, thereby filling the gap well, and can also seal the crimping part 1 and the wire 200 at the puncture part 111 well, with a good sealing effect.
[0047] In some embodiments of this application, the adhesive application area 12 is provided with an adhesive groove 121, and at least a portion of the sealant 4 is disposed in the adhesive groove 121.
[0048] In other words, by setting the glue groove 121, the sealant 4 can be better coated on the surface of the pressing part 1, which can reduce the coating difficulty. In addition, the glue groove 121 can also better limit the position of the sealant 4, so that the sealant 4 can be stably placed in the glue groove 121 when it is not under pressure.
[0049] For example, when the sealant 4 is an adhesive, the glue tank 121 can better store and hold the adhesive, which can increase the amount of adhesive applied and reduce the possibility of adhesive overflow. In addition, when the crimping part 1 is pressed against the wire 200 by the pressure, the glue tank 121 deforms. Due to the presence of the puncture member 111, the gap between the puncture area 11 and the wire 200 is larger, which allows the adhesive to be better pressed towards the puncture area 11, which can reduce the overflow of adhesive in other directions and reduce the loss of adhesive. Furthermore, the adhesive can flow towards the predetermined area (i.e., the puncture area 11), so that enough adhesive enters the puncture area 11, which can improve the reliability of the adhesive sealing the puncture area 11.
[0050] In the above example, by setting the glue groove 121, the difficulty of arranging the sealant 4 can be reduced, and the amount of glue applied can also be increased. At the same time, after the sealant 4 is arranged in the glue groove 121, the sealant 4 can also be better limited, so that the puncture can be reliably sealed after the crimping part 1 is squeezed.
[0051] In some embodiments of this application, two adhesive grooves 121 are provided along the first direction X, and the two adhesive grooves 121 are respectively located on both sides of the puncture area 11.
[0052] In other words, having two glue tanks 121 further increases the amount of sealant 4, allowing more sealant 4 to seal towards the puncture area 11, thus improving the sealing effect of the sealant 4. Furthermore, by placing the two glue tanks 121 on either side of the puncture area 11, when the pressing part 1 is under pressure, the sealant 4 stored in the two glue tanks 121 can effectively seal the puncture area 11 located in the center, further improving the sealing effect.
[0053] For example, the first direction X can refer to the length direction of the conductor 200.
[0054] For example, adhesive grooves 121 can also be provided in other locations. For instance, one adhesive groove 121 can be provided, and one adhesive groove 121 can be arranged around the puncture area 11. Alternatively, multiple adhesive grooves 121 can be provided, and multiple adhesive grooves 121 can be arranged sequentially around the outside of the puncture area 11. This application does not impose any restrictions.
[0055] In the above example, increasing the number of adhesive grooves 121 increases the amount of sealant 4, allowing more sealant 4 to seal towards the puncture area 11, thus improving the sealing effect of the sealant 4. Furthermore, by arranging the two adhesive grooves 121 on both sides of the puncture area 11, after the pressing part 1 is subjected to pressure, the sealant 4 stored in the two adhesive grooves 121 can better seal the puncture area 11 located in the middle, further improving the sealing effect.
[0056] In some embodiments of this application, the glue groove 121 is formed by stamping the crimping part 1.
[0057] In the above example, the crimping part 1, which is a metal part, can be constructed by stamping to form the glue groove 121. The operation is simple and convenient, and the shape of the glue groove 121 can be relatively flexible.
[0058] For example, the glue tank 121 can be a rectangular tank, or it can be an arc-shaped, circular, or elliptical tank, etc., and this application does not impose any restrictions.
[0059] In some embodiments of this application, along the second direction Y, the width of the adhesive groove 121 is greater than or equal to the width of the puncture area 11.
[0060] For example, the second direction Y can be perpendicular to the first direction X. For instance, the first direction X can be the length direction of the conductor 200, and the second direction Y can be the radial direction of the conductor 200.
[0061] For example, the width of the adhesive groove 121 is equal to the width of the puncture area 11.
[0062] For example, the width of the adhesive groove 121 is greater than the width of the puncture area 11.
[0063] In the above example, by designing the width of the glue groove 121 and the width of the puncture area 11, the sealant 4 in the glue groove 121 can better seal the puncture area 11, resulting in a good sealing effect and high reliability.
[0064] In some embodiments of this application, the puncture member 111 includes a protrusion, and multiple protrusions are provided, with the multiple protrusions arranged at intervals.
[0065] In other words, when the crimping part 1 is subjected to extrusion force and is pressed towards the wire 200, the area of the tip of the protrusion is small, so the force is large and it can easily pierce the oxide layer, thereby making the crimping part 1 and the wire 200 electrically connected better. By using multiple protrusions, the contact area between the crimping part 1 and the wire 200 can be increased, thereby further enhancing the electrical connection effect between the crimping part 1 and the wire 200.
[0066] In the above example, by setting a convex hull and having multiple convex hulls, the oxide layer can be pierced more effectively, and the crimping part 1 and the wire 200 can be electrically connected more effectively.
[0067] In some embodiments of this application, multiple convex hulls are arranged in a deterministic manner.
[0068] In the above example, the row-and-column arrangement of the protrusions makes the arrangement of the protrusions more orderly, which can help increase the number of protrusions, thereby increasing the contact area between the crimping part 1 and the wire 200, thus enhancing the electrical connection effect between the crimping part 1 and the wire 200. In addition, the orderly arrangement of the protrusions also helps the sealant 4 to better surround the outer periphery of the protrusions when it is squeezed toward the puncture area 11, thereby better sealing the crimping part 1 and the wire 200 at the protrusions and improving the sealing effect.
[0069] In addition, the connection is relatively stable after the crimping part 1 is pressed against the wire 200 by the protrusion.
[0070] In some embodiments of this application, the terminal block 100 further includes a plug-in portion 2 and a transition connection portion 3, the transition connection portion 3 being connected between the plug-in portion 2 and the crimp portion 1, and the width of the transition connection portion 3 being smaller than the width of the crimp portion 1 along the second direction Y.
[0071] In other words, in the direction from the plug-in portion 2 to the crimping portion 1, the plug-in portion 2 is first connected to a transition connection portion 3 with a smaller width, and then connected to a crimping portion 1 with a larger width. By making the crimping portion 1 wider, the connection between the crimping portion 1 and the wire 200 can be achieved better. In other words, the crimping portion 1 is wider, and the crimping portion 1 can better surround the outer periphery of the wire 200 along the circumference of the wire 200, which is beneficial to the connection between the crimping portion 1 and the wire 200.
[0072] For example, in the circumferential direction of the wire 200, the crimping portion 1 surrounds a portion of the outer surface of the wire 200.
[0073] For example, in the circumferential direction of the conductor 200, the crimping portion 1 can completely cover the outer surface of the outer conductor 200.
[0074] In the above example, by increasing the width of the crimping part 1, the contact area with the wire 200 can be increased, which is beneficial to the connection between the crimping part 1 and the wire 200.
[0075] In some embodiments of this application, the crimping portion 1 is integrally formed from a metal part.
[0076] In the above example, the glue groove 121 and the convex bulge can be constructed on the metal part by integral molding on the crimping part 1. The manufacturing method is simple and convenient, and the integral molding manufacturing method has good structural strength and can be well connected to the wire 200.
[0077] This application also proposes a vehicle having the terminal block 100 of the above embodiments.
[0078] According to the vehicle of the present application embodiment, by providing the terminal block 100 of the above embodiment, when the wiring is connected, it can not only connect the terminal block 100 and the wire 200 by simply pressing, but also seal the terminal block 100 and the wire 200. This can reduce the number of steps in the wiring connection of the vehicle, thereby improving the assembly efficiency of the vehicle, and also reduce the electro-corrosion in the wiring of the vehicle, and improve the stability of the wiring in the vehicle.
