Description

Terminal assemblies, connectors and crimping methods

[0001] This application claims priority to Chinese patent applications filed on October 12, 2024, with application number 202411420067.0, and filed on October 18, 2024, with application number 202411462122.2, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electrical connection technology, such as a terminal assembly, connector, and crimping method. Background Technology

[0003] Investment costs are a key constraint on the development of photovoltaic power plants. Replacing copper core conductors with aluminum core conductors can effectively reduce construction costs. Therefore, "using aluminum to save copper" has a promising future in the photovoltaic industry.

[0004] In related technologies, the connection between copper and aluminum products is mainly based on copper-aluminum friction welding, which has poor stability. Considering the widespread application and reliability of photovoltaic power plants, aluminum core conductors are usually connected to photovoltaic power plants through connectors. The connector terminal assemblies typically use riveting to clamp and fix the aluminum core conductor's core with copper terminals. During the operation of a photovoltaic power plant, the copper terminals and the conductor experience high and low temperature variations. Due to the difference in thermal deformation coefficients between copper and aluminum, the riveting between the copper terminals and the conductor may loosen, leading to increased contact resistance. This causes continuous heat generation at the connection point, affecting the normal operation of the photovoltaic power plant. Summary of the Invention

Detailed Implementation

[0042] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0044] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0045] Referring to Figures 1 to 3, this embodiment provides a terminal assembly for connection with a wire 300. The terminal assembly includes a terminal body 100 and a reinforcing member 200. The wire 300 includes a wire core 310.

[0046] In this embodiment, the terminal body 100 includes a mating section 110 and a riveting section 120 connected to each other. The riveting section 120 is used to cover and press the wire core 310 of the wire 300. The reinforcement part 200 includes a first ring portion 210 and a second ring portion 220 connected to the first ring portion 210.

[0047] The first ring 210 is sleeved on the riveting section 120 and is used to cover and press the riveting section 120; the second ring 220 protrudes from the end of the riveting section 120 away from the mating section 110 and is used to cover and press the wire core 310 of the conductor 300.

[0048] In this embodiment, the terminal body 100 covers and presses the wire core 310 with the riveting section 120, and the reinforcement 200 covers and presses the riveting section 120 with the first ring 210. During temperature changes, the structural strength of the first ring 210 can effectively prevent the riveting section 120 from loosening its pressure on the wire core 310, thereby preventing the contact resistance from increasing and causing overheating. In addition, this arrangement allows the first ring 210 and the riveting section 120 to form a conductive contact surface, and the riveting section 120 and the wire core 310 to form a conductive contact surface. This effectively increases the contact area while keeping the contact pressure basically constant, ensuring a smaller contact resistance with a more uniform and smaller riveting force (preventing deformation or breakage of the aluminum wire core), thus improving connection reliability.

[0049] In this embodiment, the reinforcement 200 covers and presses the wire core 310 with the second ring portion 220. When the wire 300 swings, it effectively prevents the end of the riveting section 120 away from the mating section 110 from squeezing or cutting the wire core 310, thereby preventing the wire core 310 from breaking at the end of the riveting section 120 away from the mating section 110. In addition, this arrangement allows the second ring portion 220 and the wire core 310 to form a contact conductive surface. The contact resistance of the second ring portion 220 is connected in series with the contact conductive surface formed by the first ring portion 210 and the riveting section 120, and then connected in series with the contact conductive surface formed by the riveting section 120 and the wire core 310. This effectively reduces the contact resistance, reduces heat generation, improves connection reliability, and overcomes problems such as resistance to external forces (swinging, etc.), internal heat (heat generation due to contact resistance), and increased internal heat caused by the coefficient of thermal expansion at different temperatures.

[0050] In some embodiments, as shown in FIG4, the reinforcement 200 may omit the second ring portion 220.

[0051] For example, the riveting section 120 covering and pressing the wire core 310 of the conductor 300 and the first ring portion 210 covering and pressing the riveting section 120 can be completed in one crimping or in steps.

[0052] For example, the first ring portion 210 covering and pressing the riveting section 120 and the second ring portion 220 covering and pressing the wire core 310 can be crimped in one step or in stages. Stepwise completion means crimping the first ring portion 210 first and then crimping the second ring portion 220; or crimping the second ring portion 220 first and then crimping the first ring portion 210.

[0053] For example, the first ring portion 210 can completely cover the riveted section 120.

[0054] For example, the second ring 220 can completely cover the portion of the wire core 310 that is pressed by the second ring 220.

[0055] In some embodiments, as shown in FIG2, the terminal body 100 further includes a backstop section 130 disposed between the mating section 110 and the riveting section 120. When the terminal assembly is disposed inside the housing, the backstop section 130 can form a backstop structure with the housing to prevent the terminal assembly from being pulled out of the housing when the wire 300 is pulled.

[0056] In some embodiments, as shown in FIG2, the riveting section 120 is configured as an open arc shape, and the wire core 310 is placed inside the open arc shape to facilitate the crimping and fixing between the riveting section 120 and the wire core 310, and to form a closed structure. Here, the open arc shape refers to the shape of the riveting section 120 before crimping the wire core 310.

[0057] For example, the cross-sectional shape of the riveting section 120 can be set to U-shape.

[0058] For example, depending on the size of the wire 300, the terminal assembly may be selected from reinforcement members 200 of different lengths and diameters.

[0059] For example, to ensure that the first ring portion 210 has good structural strength and to prevent the riveting section 120 from loosening its clamping of the wire core 310, the reinforcing member 200 can be a thicker kit. Optionally, the thickness of the reinforcing member 200 is greater than 1 mm, such as 1.2 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm.

[0060] In some embodiments, the reinforcement 200 is made of a conductive material, which helps to improve the current carrying capacity of the electrical connection between the terminal assembly and the wire core 310 and helps to reduce the occurrence of heat generation due to high contact resistance.

[0061] For example, the riveting section 120 is configured as a closed structure, meaning that the riveting section 120 can be formed into a ring-like or sleeve-like structure by crimping the wire core 310 to sleeve and press it against the outside of the wire core 310. It is understood that the first ring portion 210 does not contact the wire core 310. As shown in FIG7, there is a first contact surface 101 between the outer wall of the riveting section 120 and the inner ring of the first ring portion 210, and a second contact surface 102 between the inner wall of the riveting section 120 and the wire core 310. The double crimping of the terminal body 100 and the reinforcing member 200 helps to increase the electrical contact area between the terminal body 100 and the wire core 310, reducing contact resistance. In this embodiment, the reinforcing member 200 crimps the wire core 310 through the second ring portion 220, forming direct contact, allowing the reinforcing member 200 to participate in conductivity, i.e., the first contact surface 101 participates in conductivity. Understandably, a smaller parallel resistance and lower contact resistance improve the current-carrying capacity of the electrical connection, which is a core indicator of electrical connection performance. Let's assume the contact resistance of the first contact surface 101 is R1 and the contact resistance of the second contact surface 102 is R2. R1 and R2 are each a separate path, connected in parallel. This helps improve the current-carrying capacity of the electrical connection between the terminal assembly and the wire core 310, and reduces the heat generated by high contact resistance.

[0062] In this embodiment, the first ring portion 210 and the riveting section 120 form a contact conductive surface, and the riveting section 120 and the wire core 310 form a contact conductive surface. This effectively increases the contact area while maintaining a relatively constant contact pressure, ensuring a smaller contact resistance under a more uniform and smaller riveting force (to prevent deformation or breakage of the aluminum wire core), thus improving connection reliability. In addition, the second ring portion 220 and the wire core 310 form a contact conductive surface. Its contact resistance is connected in series with the contact resistance of the contact conductive surface formed by the first ring portion 210 and the riveting section 120, and then connected in series with the contact resistance of the contact conductive surface formed by the riveting section 120 and the wire core 310. At the same time, the second ring portion 220 and the wire core 310 are made of the same material, resulting in a relatively small and stable contact resistance, which further effectively reduces contact resistance, reduces heat generation, and improves connection reliability.

[0063] For example, the material of the reinforcement 200 and the material of the wire core 310 can be the same metal or the same type of metal alloy, so that they are not affected by electrochemical corrosion and it is beneficial to reduce the contact resistance between the terminal assembly and the wire core 310.

[0064] In one feasible implementation, the terminal body 100 is made of metallic copper or copper alloy, the reinforcement 200 is made of metallic copper or copper alloy, and the wire core 310 is made of metallic copper or copper alloy. While ensuring that the riveting section 120 presses the wire core 310 stably and reliably, the contact resistance between the terminal assembly and the wire core 310 can be reduced.

[0065] In one feasible implementation, the terminal body 100 is made of copper or a copper alloy, the reinforcement 200 is made of aluminum or an aluminum alloy, and the wire core 310 is made of aluminum or an aluminum alloy to achieve the connection between the terminal assembly and the aluminum core wire. This ensures stable and reliable compression of the wire core 310 by the riveting section 120 while reducing the contact resistance between the terminal assembly and the wire core 310. In this embodiment, when the terminal body 100 is applied to a photovoltaic power station, the aluminum core wire can be selected as a conductor 300 formed by twisting multiple strands of wire core 310, such as a 7+1 aluminum core wire, a 6+1 aluminum core wire, a 5+1 aluminum core wire, or other quantities of aluminum core wire. The twisted wire cores 310 have high strength, and when the riveting section 120 presses down on the wire core 310, the wire core 310 undergoes compression deformation and misalignment, and the original oxide layer on the surface of the wire core 310 is destroyed. This ensures reliable and stable electrical connections between wire cores 310 and between the wire core 310 and the riveting section 120. Aluminum core conductors can also use single-strand core 310.

[0066] For example, the terminal body 100 can also be made of copper-aluminum composite material, such as by casting, brazing, hot pressing, friction welding and other different methods, and then processed by cold heading, turning and other processes.

[0067] For example, to prevent electrochemical corrosion between the riveting section 120 and the wire core 310 and between the riveting section 120 and the reinforcement 200, the riveting section 120 is covered with a tin-plated layer (not shown), that is, to prevent the wire core 310 and the reinforcement 200 from directly contacting the riveting section 120.

[0068] The tin plating layer has a large plating thickness, which can prevent the tin plating layer from tearing due to deformation of the riveting section 120 during the crimping process, and thus more effectively prevent the riveting section 120 from directly contacting the wire core 310 and causing electrochemical corrosion.

[0069] For example, the reinforcement 200 may also be covered with a tin plating layer.

[0070] The reinforcement 200 can also be made of insulating material, conductive material different from the material of the wire core 310, etc., and this application does not limit it.

[0071] In one feasible embodiment, the terminal assembly further includes conductive paste (not shown) filled between the riveting segment 120 and the wire core 310 of the conductor 300. Exemplarily, before crimping the riveting segment 120, conductive paste may be applied to at least one of the riveting segment 120 and the wire core 310. For example, by applying conductive paste to the wire core 310, after crimping the riveting segment 120, the conductive paste can fill the gap between the riveting segment 120 and the wire core 310, and can isolate the wire core 310 from contact with air, effectively preventing oxidation of the wire core 310. Exemplarily, conductive paste may also be filled between the wire core 310 and the reinforcing member 200.

[0072] In some embodiments, the expansion coefficient of the reinforcement 200 may be the same as or similar to that of the wire core 310. The first ring portion 210 covers and presses against the riveting section 120, and the second ring portion 220 covers and presses against the wire core 310. Both the terminal body 100 and the wire core 310 are conductive to the reinforcement 200, which can effectively reduce the resistance at the connection between the terminal assembly and the wire 300, increase the conductive contact area of ​​the terminal body 100 to reduce contact resistance, and thus reduce heat generation. Furthermore, the expansion coefficients of the reinforcement 200 and the wire core 310 are the same or similar, which effectively prevents the second ring portion 220 from loosening its pressure on the wire core 310, ensuring a stable and reliable electrical connection between the reinforcement 200 and the wire 300. In this embodiment, the expansion coefficient of the reinforcement 200 being similar to that of the wire core 310 means that the difference between their expansion coefficients is less than 20 μm / m·K.

[0073] In some embodiments, the expansion coefficient of the terminal body 100 may be different from that of the wire core 310. By setting the reinforcement 200, the deformation effect caused by the difference in expansion coefficients between the riveting section 120 and the wire core 310 can be weakened, effectively preventing the riveting section 120 and the first ring 210 from loosening their pressure on the wire core 310 during temperature changes, thereby preventing the contact resistance from increasing and causing heat generation.

[0074] In some embodiments, as shown in Figures 3, 5 to 11, the conductor 300 further includes an outer jacket 320 that is sleeved over the conductor core 310.

[0075] Exemplarily, the core 310 includes a first core segment 311 and a second core segment 312. Both the first core segment 311 and the second core segment 312 extend out of the outer jacket 320 along the axial direction of the conductor 300. The first core segment 311 is located at the end of the second core segment 312 opposite to the outer jacket 320. A riveting section 120 is used to cover and press the first core segment 311, and a second ring portion 220 is used to cover and press the second core segment 312. It is understood that the second core segment 312 protrudes from the end of the riveting section 120 opposite to the mating section 110. In a feasible embodiment, the reinforcement 200 further includes a third ring portion 230 connected to the second ring portion 220, the third ring portion 230 being fitted over the outer jacket 320. In this embodiment, when the conductor 300 swings, the third ring portion 230 can constrain the outer jacket 320 to prevent the wire core 310 extending out of the outer jacket 320 from bending excessively. This helps to reduce the degree to which the riveting section 120 and the second ring portion 220 cut the wire core 310, and helps to reduce the risk of the wire core 310 extending out of the outer jacket 320 breaking.

[0076] For example, the third ring portion 230 can cover and press the outer jacket 320. In this embodiment, the third ring portion 230 can be pressed onto the outer jacket 320 after the second ring portion 220 is crimped onto the wire core 310, or the first ring portion 210, the second ring portion 220 and the third ring portion 230 can be crimped simultaneously.

[0077] In another feasible embodiment, the end of the second ring portion 220 facing away from the first ring portion 210 includes a limiting surface 221, which can abut against the end of the outer jacket 320 of the conductor 300 to prevent the core 310 extending out of the outer jacket 320 from bending excessively when the conductor 300 swings. In this embodiment, the first ring portion 210 covering and pressing the riveting section 120 and the second ring portion 220 covering and pressing the core 310 can be completed in steps. For example, the second ring portion 220 can be crimped first to ensure that the limiting surface 221 abuts against the end of the outer jacket 320, and then the first ring portion 210 can be crimped.

[0078] For example, the end of the second ring portion 220 that is away from the first ring portion 210 may not press against the wire core 310, so as to reduce the deformation of the limiting surface 221 and form a good fit between the limiting surface 221 and the end of the outer sleeve 320.

[0079] For example, along the axial direction of the reinforcement 200, a gap may also be formed between the limiting surface 221 and the end of the outer sleeve 320, which makes it easier to crimp the reinforcement 200.

[0080] In some embodiments, as shown in Figures 12 to 16, the core 310 includes not only a first core segment 311 and a second core segment 312, but also a reserved core segment 313. The reserved core segment 313, the first core segment 311, and the second core segment 312 are connected sequentially, and the reserved core segment 313 and the first core segment 311 are bent towards each other. It is understood that the reserved core segment 313 is located outside the outer jacket 320.

[0081] In one feasible implementation, the riveting section 120 is used to cover and press the first core section 311; the first ring 210 is sleeved on the riveting section 120 and the reserved core section 313, and the first ring 210 is used to cover and press the riveting section 120 and the reserved core section 313; the second ring 220 is sleeved on the second core section 312, and the second ring 220 is used to cover and press the second core section 312. In this embodiment, the terminal body 100 covers and presses the first core section 311 through the riveting section 120, and the reinforcement 200 covers and presses the riveting section 120 and the reserved core section 313 through the first ring 210. The reserved core section 313 will deform under compression and fill the gap between the first ring 210 and the riveting section 120, which is beneficial to improving the crimping stability of the first ring 210. Furthermore, the reinforcement 200 covers and presses the riveting section 120 and the reserved core section 313 through the first ring 210, which helps to increase the cross-sectional area of ​​the core 310 at the riveting section 120 and increase the contact area between the core 310 and the riveting section 120, thereby helping to reduce the contact resistance between the terminal assembly and the core 310 and further preventing overheating.

[0082] In some embodiments, as shown in FIG17, when the wire core 310 includes a reserved core segment 313, the reinforcement member 200 may not have the second ring portion 220. The wire core 310 may or may not include the second core segment 312.

[0083] For example, the riveting section 120 covering and pressing the first core section 311 and the first ring portion 210 covering and pressing the riveting section 120 and the reserved core section 313 can be completed in one crimping or in steps.

[0084] For example, before riveting the terminal body 100 and the wire core 310, the wire core 310 may not be bent, that is, the first core segment 311 and the reserved core segment 313 may remain straight, or the reserved core segment 313 may be bent at a small angle relative to the first core segment 311 to accommodate the first core segment 311 passing through the riveting section 120. After the first core segment 311 passes through the riveting section 120, the reserved core segment 313 may be bent at the required angle relative to the first core segment 311 to accommodate the first ring portion 210 fitting onto the riveting section 120 and the reserved core segment 313. Alternatively, the riveting section 120 and the first core segment 311 may be crimped first, and then the reserved core segment 313 may be bent relative to the first core segment 311; or the riveting section 120 may be wrapped around the first core segment 311 first, and then the reserved core segment 313 may be bent relative to the first core segment 311 before crimping the riveting section 120 and the first core segment 311.

[0085] For example, the first ring portion 210 covering and pressing the riveting section 120 and the reserved core section 313, and the second ring portion 220 covering and pressing the second core section 312 can be completed in one crimping or in steps.

[0086] For example, when the reinforcement 200 includes the third ring portion 230, the third ring portion 230 can be pressed onto the outer sleeve 320 after the second ring portion 220 is pressed onto the second core segment 312, or the first ring portion 210, the second ring portion 220 and the third ring portion 230 can be pressed onto the outer sleeve 320 at the same time.

[0087] For example, when the riveting section 120 is set to an open arc shape, such as when the cross-sectional shape of the riveting section 120 is U-shaped, after the riveting section 120 presses against the first core section 311, the reserved core section 313 is located at the two open edges of the riveting section 120. By pressing the reserved core section 313 against the two open edges of the riveting section 120, the pressing of the riveting section 120 against the first core section 311 is effectively prevented from loosening.

[0088] In one feasible implementation, as shown in Figures 12 and 16, a reserved core segment 313 protrudes from the end of the riveting section 120 opposite to the mating section 110, and the length of the reserved core segment 313 is greater than the length of the first core segment 311; a second ring portion 220 is sleeved on the second core segment 312 and the reserved core segment 313, and the second ring portion 220 is used to cover and press the second core segment 312 and the reserved core segment 313. It is understood that when the length of the reserved core segment 313 is less than or equal to the length of the first core segment 311, the second ring portion 220 is not sleeved on the reserved core segment 313.

[0089] It is understandable that if the length of the reserved core segment 313 is greater than the length of the first core segment 311, then the first ring 210 covers and presses a portion of the reserved core segment 313, and the second ring 220 covers and presses the remaining portion of the reserved core segment 313 excluding the portion pressed by the first ring 210.

[0090] For example, the first ring portion 210 covering and pressing the riveting section 120 and the reserved core section 313, and the second ring portion 220 covering and pressing the second core section 312 and the reserved core section 313, can be completed in one crimping operation or in stages. Staged completion means that the first ring portion 210 is crimped first, and then the second ring portion 220 is crimped; or the second ring portion 220 is crimped first, and then the first ring portion 210 is crimped.

[0091] For example, when the reinforcement 200 includes the third ring portion 230, the third ring portion 230 can be pressed onto the outer sleeve 320 after the second ring portion 220 has been pressed onto the second core segment 312 and the reserved core segment 313. Alternatively, the first ring portion 210, the second ring portion 220 and the third ring portion 230 can be pressed onto the outer sleeve 320 at the same time.

[0092] As can be understood, as shown in Figure 15, the reinforcing member 200 is made of a conductive material, the riveting section 120 is a closed structure, and the first ring portion 210 does not contact the first core segment 311. Specifically, the outer wall of the riveting section 120 and the reserved core segment 313 have a third contact surface 103 that contacts each other, and the inner ring of the first ring portion 210 and the reserved core segment 313 have a fourth contact surface 201 that contacts each other. In this embodiment, the reinforcing member 200 presses the second core segment 312 and the reserved core segment 313 together through the second ring portion 220, so that the first contact surface 101, the third contact surface 103, and the fourth contact surface 201 all participate in conductivity. Assume the contact resistance of the first contact surface 101 between the outer wall of the riveting section 120 and the inner ring of the first ring 210 is set as r1, the contact resistance of the second contact surface 102 between the inner wall of the riveting section 120 and the first core segment 311 is set as r2, the contact resistance of the third contact surface 103 between the outer wall of the riveting section 120 and the reserved core segment 313 is set as r3, and the contact resistance of the fourth contact surface 201 between the inner ring of the first ring 210 and the reserved core segment 313 is set as r4. Here, r1 and r4 are connected in series (one path), r2 is another path, and r3 is yet another path; that is, r1 and r4 are connected in series and then in parallel with r2 and r3, resulting in three parallel paths. This helps improve the current-carrying capacity of the electrical connection between the terminal assembly and the wire core 310 and helps reduce the occurrence of overheating due to high contact resistance.

[0093] In some embodiments, as shown in Figures 18 and 19, the first ring portion 210 is provided with an opening 211, which is arranged along the axial direction of the reinforcing member 200, and the first end of the opening 211 passes through one end of the first ring portion 210 away from the second ring portion 220. In this embodiment, by providing the opening 211, even if the riveting section 120 undergoes a large deformation after crimping, the first ring portion 210 can still be smoothly fitted onto the riveting section 120, or the first ring portion 210 can also be smoothly fitted onto the riveting section 120 and the reserved core section 313, so as to facilitate the crimping of the first ring portion 210.

[0094] In one feasible implementation, along the axial direction of the reinforcing member 200, the second end of the opening 211 may extend onto the second ring portion 220 to facilitate the crimping of the first ring portion 210 and the second ring portion 220. Exemplarily, the second end of the opening 211 may extend to the central region of the second ring portion 220, an end of the second ring portion 220 opposite to the first ring portion 210, or other regions of the second ring portion 220; this application is not limited to these locations. It is understood that the first end and the second end of the opening 211 refer to the opposite ends of the opening 211 along the axial direction of the reinforcing member 200.

[0095] In one feasible implementation, along the axial direction of the reinforcing member 200, the second end of the opening 211 penetrates the reinforcing member 200, that is, both ends of the opening 211 penetrate the reinforcing member 200. The reinforcing member 200 is a ring sleeve of the opening 211, and the reinforcing member 200 is more prone to deformation when crimped. For example, the third ring portion 230 can undergo greater deformation when the first ring portion 210 and the second ring portion 220 are crimped, which can better constrain the outer sleeve 320 and more effectively prevent the core 310 extending out of the outer sleeve 320 from breaking.

[0096] In one feasible implementation, since the reinforcement 200 has an opening 211, a locking clamp (not shown) can be fitted onto the reinforcement 200 to prevent deformation.

[0097] In some embodiments, as shown in FIG20, the reinforcement 200 is configured as a closed ring structure, that is, the reinforcement 200 may not have an opening 211, making the crimping more stable and reliable.

[0098] This embodiment also provides a connector, as shown in Figures 21 to 23, the connector includes a male connector 400, or the connector includes a female connector 500, or the connector includes both a male connector 400 and a female connector 500.

[0099] For example, the male connector 400 includes a first housing 410, within which the terminal assembly described above is disposed.

[0100] For example, the female connector 500 includes a second housing 510, within which the terminal assembly described above is disposed.

[0101] In this embodiment, the terminal assembly configuration effectively ensures a stable and reliable connection between the male connector 400 and the wire 300, as well as between the female connector 500 and the wire 300, and effectively reduces the contact resistance between the terminal assembly and the wire core 310, thereby preventing overheating.

[0102] In some embodiments, the terminal assembly within the first housing 410 and the terminal assembly within the second housing 510 are electrically connected, i.e., the male connector 400 and the female connector 500 are electrically connected by mating the two terminal assemblies. Both the first housing 410 and the second housing 510 can form a backstop structure with the backstop section 130.

[0103] For example, when the connector is used to connect aluminum core wires, one of the two aluminum core wires is connected to the male connector 400 and the other is connected to the female connector 500. Optionally, the terminal body 100 can be made of copper or copper alloy, and the reinforcement 200 can be made of aluminum or aluminum alloy.

[0104] For example, when the connector is used for connection between aluminum core wires and copper core wires, one of the male connector 400 and the female connector 500 is connected to the aluminum core wire, and the other is connected to the copper core wire. Optionally, the terminal body 100 of the terminal assembly connected to the aluminum core wire can be made of metallic copper or a copper alloy, and the reinforcing member 200 can be made of metallic aluminum or an aluminum alloy. Optionally, the terminal body 100 of the terminal assembly connected to the copper core wire can be made of metallic copper or a copper alloy. Optionally, the terminal assembly connected to the copper core wire may not have the reinforcing member 200, or the reinforcing member 200 of the terminal assembly connected to the copper core wire can be made of metallic copper or a copper alloy.

[0105] In some embodiments, the mating section 110 of the terminal body 100 of the terminal assembly of one of the male connector 400 and the female connector 500 is electrically connected to the wire 300 to achieve an electrical connection between the two wires 300.

[0106] For example, the material of the core 310 of the wire 300 electrically connected to the docking section 110 and the material of the terminal body 100 can be the same metal or the same type of metal alloy, such as copper or copper alloy.

[0107] In some embodiments, as shown in Figures 22 and 23, the male connector 400 and the female connector 500 are detachably connected. When the first housing 410 and the second housing 510 are connected together, the mating section 110 of the terminal body 100 of the terminal assembly in the first housing 410 and the mating section 110 of the terminal body 100 of the terminal assembly in the second housing 510 are mated to each other.

[0108] Exemplarily, one of the first housing 410 and the second housing 510 is provided with a buckle 411, and the other is provided with a slot (not shown). The first housing 410 and the second housing 510 are detachably connected by the snap-fit ​​engagement between the buckle 411 and the slot. Optionally, the first housing 410 is provided with a plurality of buckles 411 spaced circumferentially at one end facing the second housing 510, and the second housing 510 is provided with slots corresponding one-to-one with the buckles 411. The buckles 411 can extend into the second housing 510 and engage with the slots stably and reliably. The male connector 400 and the female connector 500 can also be connected by a threaded connection or other detachable methods, which are not limited in this application.

[0109] In some embodiments, as shown in Figures 22 and 23, one of the mating section 110 of the terminal body 100 of the terminal assembly within the first housing 410 and the mating section 110 of the terminal body 100 of the terminal assembly within the second housing 510 is provided with a slot 111, and the other is inserted into the slot 111 to realize the electrical connection between the male connector 400 and the female connector 500. Furthermore, the core 310 of the wire 300 can be directly inserted into the slot 111.

[0110] In one feasible embodiment, the terminal body 100 of the terminal assembly inside the first housing 410 has a slot 111 for its mating section 110. The first housing 410 has a guide sleeve 412 at one end facing the second housing 510, and the second housing 510 has a guide groove (not shown) at one end facing the first housing 410. The guide sleeve 412 can slide through the guide groove to ensure precise mating between the two mating sections 110. Specifically, the mating section 110 of the terminal body 100 inside the first housing 410 extends into the guide sleeve 412, and the mating section 110 of the terminal body 100 inside the second housing 510 extends into the guide groove.

[0111] For example, the guide sleeve 412 is provided with a drum-shaped ring 420, and the mating section 110 of the terminal body 100 in the second housing 510 passes through the drum-shaped ring 420 and is inserted into the slot 111 of the mating section 110 of the terminal body 100 in the first housing 410.

[0112] For example, the first housing 410 has a boss 413 at one end facing the second housing 510, a guide sleeve 412 is provided on the boss 413, and an O-ring 430 is fitted on the boss 413. The guide groove has a groove (not shown) at one end facing the first housing 410. The boss 413 can extend into the groove, and the O-ring 430 can abut against the side wall of the groove to play a sealing and shock-absorbing role.

[0113] In some embodiments, as shown in FIG22, a first cap 440 is fitted onto one end of the first housing 410 away from the second housing 510. The wire 300 connected to the male connector 400 passes through the first cap 440 and extends into the first housing 410 to be crimped with the riveting section 120 of the terminal body 100.

[0114] For example, the first outer shell 410 and the first cap 440 can be connected by a threaded connection, or by a snap-fit ​​or adhesive connection, etc., and this application does not limit the connection.

[0115] In one feasible embodiment, a first sealing ring 450 is provided between the first housing 410 and the first cap 440. The wire 300 connected to the male connector 400 passes through the first sealing ring 450 and extends into the first housing 410. In this embodiment, by pressing the first sealing ring 450 against the first housing 410 and the first cap 440, the first sealing ring 450 can be pressed and fixed to the wire 300, effectively preventing the wire 300 extending into the first housing 410 from swinging, and also playing a role in sealing and shock absorption.

[0116] For example, the outer ring of the first sealing ring 450 can be conical, the small end of the first sealing ring 450 can extend into the first housing 410, and the large end of the first sealing ring 450 is embedded in the first cap 440.

[0117] In some embodiments, as shown in FIG23, a second cap 520 is fitted onto one end of the second housing 510 away from the first housing 410. The wire 300 connected to the female connector 500 passes through the second cap 520 and extends into the second housing 510 to be crimped with the riveting section 120 of the terminal body 100.

[0118] For example, the second housing 510 and the second cap 520 can be connected by a threaded connection, or by a snap-fit ​​or adhesive connection, etc., and this application does not limit the connection.

[0119] In one feasible embodiment, a second sealing ring 530 is provided between the second housing 510 and the second cap 520. The wire 300 connected to the female connector 500 passes through the second sealing ring 530 and extends into the second housing 510. In this embodiment, by pressing the second sealing ring 530 against the second housing 510 and the second cap 520, the second sealing ring 530 can be pressed and fixed to the wire 300, effectively preventing the wire 300 extending into the second housing 510 from swinging, and also playing a role in sealing and shock absorption.

[0120] For example, the outer ring of the second sealing ring 530 can be conical, the small end of the second sealing ring 530 can extend into the second housing 510, and the large end of the second sealing ring 530 is embedded in the second cap 520.

[0121] Referring to FIG24, this embodiment also provides a crimping method, which can effectively prevent the terminal assembly from loosening its crimping of the wire core 310 and effectively reduce the contact resistance between the terminal assembly and the wire core 310, thereby preventing overheating.

[0122] The crimping method includes the following steps:

[0123] S100, providing a terminal body 100 and a wire 300, placing the wire core 310 of the wire 300 on the riveting section 120 of the terminal body 100;

[0124] S200, Provide reinforcement 200, and fit reinforcement 200 onto wire 300;

[0125] S300: First, crimp the riveting section 120 and the wire core 310, then crimp the first ring portion 210 of the reinforcing member 200 onto the riveting section 120, and crimp the second ring portion 220 of the reinforcing member 200 onto the wire core 310; or, crimp the first ring portion 210 of the reinforcing member 200 onto the riveting section 120, and simultaneously crimp the riveting section 120 and the wire core 310, and crimp the second ring portion 220 of the reinforcing member 200 onto the wire core 310.

[0126] It is understandable that crimping the riveting section 120 and the wire core 310 first, then crimping the first ring 210 of the reinforcement 200 onto the riveting section 120, and then crimping the second ring 220 of the reinforcement 200 onto the wire core 310, helps to ensure crimping accuracy and quality.

[0127] It is understandable that pressing the first ring portion 210 of the reinforcing member 200 onto the riveting section 120, and simultaneously pressing the riveting section 120 and the wire core 310, and pressing the second ring portion 220 of the reinforcing member 200 onto the wire core 310, helps to speed up the pressing process.

[0128] Steps S100 and S200 are not in any particular order.

[0129] In one feasible implementation, when the wire core 310 includes a reserved core segment 313, step S300 includes the following steps:

[0130] First, crimp the riveting section 120 onto the first core segment 311 of the wire core 310. Then, crimp the first ring portion 210 of the reinforcing member 200 onto the riveting section 120 and the reserved core segment 313 of the wire core 310, and crimp the second ring portion 220 of the reinforcing member 200 onto the second core segment 312 of the wire core 310. Alternatively, crimp the first ring portion 210 of the reinforcing member 200 onto the riveting section 120 and the reserved core segment 313 of the wire core 310, and simultaneously crimp the riveting section 120 onto the first core segment 311 of the wire core 310, and crimp the second ring portion 220 of the reinforcing member 200 onto the second core segment 312 of the wire core 310.

[0131] It is understandable that the riveting section 120 is first pressed onto the first core segment 311 of the wire core 310, then the first ring portion 210 of the reinforcing member 200 is pressed onto the riveting section 120 and the reserved core segment 313 of the wire core 310, and the second ring portion 220 of the reinforcing member 200 is pressed onto the second core segment 312 of the wire core 310, which can ensure the crimping accuracy and quality.

[0132] It is understandable that pressing the first ring portion 210 of the reinforcing member 200 onto the riveting section 120 and the reserved core section 313 of the wire core 310, while simultaneously pressing the riveting section 120 onto the first core section 311 of the wire core 310 and pressing the second ring portion 220 of the reinforcing member 200 onto the second core section 312 of the wire core 310, can speed up the pressing process.

[0133] In another feasible implementation, when the wire core 310 includes a reserved core segment 313, step S300 includes the following steps:

[0134] First, crimp the riveting section 120 onto the first core segment 311 of the wire core 310. Then, crimp the first ring portion 210 of the reinforcing member 200 onto the riveting section 120 and the reserved core segment 313 of the wire core 310, and crimp the second ring portion 220 of the reinforcing member 200 onto the second core segment 312 and the reserved core segment 313 of the wire core 310. Alternatively, crimp the first ring portion 210 of the reinforcing member 200 onto the riveting section 120 and the reserved core segment 313 of the wire core 310, and simultaneously crimp the riveting section 120 onto the first core segment 311 of the wire core 310, and crimp the second ring portion 220 of the reinforcing member 200 onto the second core segment 312 and the reserved core segment 313 of the wire core 310.

[0135] It is understandable that the riveting section 120 is first pressed onto the first core section 311 of the wire core 310, then the first ring portion 210 of the reinforcing member 200 is pressed onto the riveting section 120 and the reserved core section 313 of the wire core 310, and the second ring portion 220 of the reinforcing member 200 is pressed onto the second core section 312 and the reserved core section 313 of the wire core 310, which can ensure the crimping accuracy and quality.

[0136] It is understandable that pressing the first ring portion 210 of the reinforcement member 200 onto the riveting section 120 and the reserved core section 313 of the wire core 310, while simultaneously pressing the riveting section 120 onto the first core section 311 of the wire core 310, and pressing the second ring portion 220 of the reinforcement member 200 onto the second core section 312 and the reserved core section 313 of the wire core 310, can speed up the pressing process.

[0137] In some embodiments, when the reinforcement 200 includes a first ring portion 210, a second ring portion 220, and a third ring portion 230, step S300 further includes the following step:

[0138] The third ring 230 of the reinforcement 200 is pressed onto the outer jacket 320 of the wire 300.

[0139] Understandably, pressing the third ring portion 230 of the reinforcement 200 onto the outer jacket 320 of the conductor 300 can prevent the wire core 310 extending out of the outer jacket 320 from being excessively bent, which helps to reduce the degree to which the riveting section 120 and the second ring portion 220 cut the wire core 310, and helps to reduce the risk of the wire core 310 extending out of the outer jacket 320 breaking.

[0140] For example, when the wire core 310 does not include the reserved core segment 313, the first ring portion 210 and the riveting segment 120, the second ring portion 220 and the wire core 310, and the third ring portion 230 and the outer sleeve 320 are crimped sequentially to ensure crimping accuracy and quality. Alternatively, when the wire core 310 does not include the reserved core segment 313, the first ring portion 210 and the riveting segment 120, the second ring portion 220 and the wire core 310, and the third ring portion 230 and the outer sleeve 320 are crimped simultaneously to speed up the crimping process.

[0141] For example, when the wire core 310 includes a reserved core segment 313, and the length of the reserved core segment 313 is less than or equal to the length of the first core segment 311, the first ring portion 210 of the reinforcement member 200 is pressed onto the riveting section 120 and the reserved core segment 313 of the wire core 310 in sequence, the second ring portion 220 of the reinforcement member 200 is pressed onto the second core segment 312 of the wire core 310, and the third ring portion 230 of the reinforcement member 200 is pressed onto the outer jacket 320 of the conductor 300 to ensure crimping accuracy and quality. Alternatively, when the wire core 310 includes a reserved core segment 313, and the length of the reserved core segment 313 is less than or equal to the length of the first core segment 311, the first ring portion 210 of the reinforcing member 200 is simultaneously pressed onto the riveting section 120 and the reserved core segment 313 of the wire core 310, the second ring portion 220 of the reinforcing member 200 is pressed onto the second core segment 312 of the wire core 310, and the third ring portion 230 of the reinforcing member 200 is pressed onto the outer jacket 320 of the conductor 300, so as to speed up the crimping speed.

[0142] For example, when the wire core 310 includes a reserved core segment 313, and the length of the reserved core segment 313 is greater than the length of the first core segment 311, the first ring portion 210 of the reinforcing member 200 is pressed onto the riveting section 120 and the reserved core segment 313 of the wire core 310 in sequence, the second ring portion 220 of the reinforcing member 200 is pressed onto the second core segment 312 and the reserved core segment 313 of the wire core 310, and the third ring portion 230 of the reinforcing member 200 is pressed onto the outer jacket 320 of the conductor 300 to ensure crimping accuracy and quality. Alternatively, when the wire core 310 includes a reserved core segment 313, and the length of the reserved core segment 313 is greater than the length of the first core segment 311, the first ring portion 210 of the reinforcing member 200 is simultaneously pressed onto the riveting section 120 and the reserved core segment 313 of the wire core 310, the second ring portion 220 of the reinforcing member 200 is pressed onto the second core segment 312 and the reserved core segment 313 of the wire core 310, and the third ring portion 230 of the reinforcing member 200 is pressed onto the outer jacket 320 of the conductor 300 to speed up the crimping process.

[0143] In summary, the terminal assembly provided in this application has a terminal body that covers and presses the wire core with a riveting section, and a reinforcement part that covers and presses the riveting section with a first ring. During temperature changes, the structural strength of the first ring can effectively prevent the riveting section from loosening its pressure on the wire core, thereby preventing the contact resistance from increasing and causing overheating. Furthermore, the reinforcement part covers and presses the wire core with a second ring, forming a new conductive contact surface and further reducing the contact resistance. At the same time, when the wire swings, it effectively prevents the end of the riveting section away from the mating section from squeezing or cutting the wire core, thereby preventing the wire core from breaking at the end of the riveting section away from the mating section.

[0144] The connector provided in this application has terminal assemblies in the first and second housings respectively, so as to ensure stable and reliable connection between the male connector and the wire and between the female connector and the wire, and effectively reduce the contact resistance between the terminal assembly and the wire core, thereby preventing overheating.

[0145] The crimping method provided in this application can effectively prevent the terminal assembly from loosening its clamping of the wire core and effectively reduce the contact resistance between the terminal assembly and the wire core, thereby preventing overheating.
