[0032] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-8 The cable terminal 100 according to a first aspect embodiment of the present invention is described.

[0033] like Figures 1-5 As shown, the cable terminal 100 according to the first aspect of the present invention includes: a connector 10 and a locking member 20.

[0034] The connector 10 includes a mating part 11 and an elastic part 12, wherein the elastic part 12 is connected axially to the mating part 11 (e.g., Figure 1 At one end (in the left-right direction), the elastic part 12 has a plurality of elastic pieces 121, which are arranged along the circumferential direction of the mating part 11 (e.g., in the left-right direction). Figure 1 The elastic pieces 121 are arranged at intervals in the vertical direction, and together they define a mounting cavity 40, which is suitable for mounting a cable 30. In the description of this utility model, "multiple" means two or more. A locking member 20 is sleeved on the outer periphery of the elastic part 12. The locking member 20 has a locked state and an unlocked state. When the locking member 20 is in the locked state, it locks the cable 30 in the mounting cavity 40. When the locking member 20 is in the unlocked state, the cable 30 can be separated from the mounting cavity 40.

[0035] For example, in Figures 1-4 In the example, the mating part 11 is a hollow cylindrical structure, and the elastic sheet 121 extends along the axial direction of the mating part 11. The number of elastic sheets 121 is 4, but not limited to this.

[0036] When the locking member 20 is in the unlocked state, the cable 30 is installed in the mounting cavity 40. At this time, multiple elastic pieces 121 are arranged at intervals along the outer periphery of the cable 30, and there is a gap between the elastic pieces 121 and the cable 30. By switching the locking member 20 from the unlocked state to the locked state, the multiple elastic pieces 121 are moved from the outside of the cable 30 to the axial direction of the cable 30, so that the multiple elastic pieces 121 press the cable 30, thereby locking the cable 30 in the mounting cavity 40.

[0037] The cable 30 is secured by the elastic plate 121 structure of the elastic part 12. During installation, the cable 30 is simply inserted into the mounting cavity 40, and the elastic plate 121 applies clamping force to the cable 30 through its own elastic deformation to secure it. No additional tools are needed to apply pressure, reducing reliance on specialized tools and operator skills. Furthermore, the way the elastic part 12 cooperates with the locking member 20 simplifies the operation steps, thereby reducing construction time and labor costs. In addition, multiple elastic plates 121 can apply force evenly to the cable 30 from multiple directions, preventing incomplete crimping or terminal damage due to operator errors during crimping, thus improving the electrical performance and operational stability of the connector 200. Moreover, by increasing the number of elastic plates 121, the contact area between the elastic plates 121 and the cable 30 can be increased, allowing the elastic plates 121 to more reliably clamp the cable 30.

[0038] According to the embodiment of the present invention, the cable terminal 100 connects the elastic part 12 with the mating part 11 and sleeves the locking member 20 on the outer periphery of the elastic part 12. No additional tools are needed to apply pressure, which reduces the dependence on professional tools and operator skills, simplifies the operation steps, thereby reducing construction time and labor costs, avoiding incomplete crimping or terminal damage due to operator errors during the crimping process, and improving the electrical performance and stability of the connector 200.

[0039] It should be noted that the elastic part 12 can be made of materials with good elasticity, such as alloy copper, and this application does not impose specific restrictions on this.

[0040] According to some embodiments of the present invention, the locking member 20 includes a body 21 and at least one locking buckle 22. The body 21 has a plurality of locking grooves 211 formed thereon, which are arranged at intervals along the circumference of the body 21. The locking buckle 22 is located on one side of the body 21 in the thickness direction, and can selectively engage with at least one of the plurality of locking grooves 211.

[0041] For example, in Figure 5In the example, when the locking buckle 22 is engaged in the locking groove 211, the body 21 is generally in the shape of a ring, and part of the body 21 overlaps along the thickness direction of the body 21. The locking buckle 22 extends obliquely along the thickness direction of the body 21. The locking groove 211 is generally in the shape of a square through groove. The number of locking grooves 211 can be 14, but is not limited to this. The locking buckle 22 is set near the first end of the body 21, and one of the multiple locking grooves 211 that is far away from the key buckle is set near the second end of the body 21.

[0042] Multiple locking grooves 211 are arranged at intervals along the circumference of the body 21, providing multiple selectable fixed positions for the locking buckle 22. The locking buckle 22 cooperates with the locking grooves 211 at different positions, which can flexibly adjust the diameter of the body 21 of the locking member 20, thereby allowing the elastic member to switch between the locked state and the unlocked state.

[0043] For example, when the locking buckle 22 engages with one of the locking slots 211 closest to the second end of the body 21, the diameter of the body 21 is larger, allowing the elastic part 12 to switch to the unlocked state. The multiple elastic pieces 121 then recover their elastic deformation and move away from the cable 30, allowing for the assembly or disassembly of the cable 30. When the locking buckle 22 engages with one of the locking slots 211 closest to the first end of the body 21, the diameter of the body 21 is smaller, allowing the elastic part 12 to switch to the locked state. The multiple elastic pieces 121 then undergo elastic deformation and move towards the cable 30, allowing the elastic part 12 to press the cable 30 firmly. This configuration simplifies operation, eliminates the need for additional tools to apply pressure, and reduces construction time and labor costs. Furthermore, the arrangement of multiple locking slots 211 can accommodate cables 30 of different sizes and specifications, thereby improving the applicability of the cable terminal 100.

[0044] It should be noted that the locking component 20 can be made of materials with strong resistance to deformation, such as engineering plastics or metals, and this application does not impose specific restrictions on this.

[0045] Furthermore, there are multiple locking latches 22, each including at least one first locking latch 221 and at least one second locking latch 222, which are arranged at intervals along the axial direction of the body 21. There are also multiple locking grooves 211, including multiple first locking grooves 2111 and multiple second locking grooves 2112, which are also arranged at intervals along the axial direction of the body 21.

[0046] The first locking buckle 221 may be selectively fitted into at least one of the plurality of first locking grooves 2111, and the second locking buckle 222 may be selectively fitted into at least one of the plurality of second locking grooves 2112.

[0047] For example, in Figure 5 In the example, there can be two locking buckles 22 and 14 locking slots 211, of which there are 7 first locking slots 2111 and 7 second locking slots 2112, but this is not limited to these. The first locking buckles 221 and the second locking buckles 222 are arranged together to prevent the locking member 20 from losing its locking function if one of the first locking buckles 221 or the second locking buckle 222 comes out of the corresponding locking slot 211. This provides a more reliable locking function for the elastic part 12, improves the overall working reliability of the cable terminal 100, and thus improves the electrical performance and operational stability of the connector 200.

[0048] According to some embodiments of the present invention, the locking member 20 further includes: a handle portion 23, the two ends of the handle portion 23 being connected to the two ends of the axial direction of the body 21 respectively, the handle portion 23 and the body 21 jointly defining a channel, and the locking buckle 22 being located within the channel.

[0049] like Figure 5 As shown, the handle 23 and the locking buckle 22 are located on the same side of the thickness direction of the body 21. When adjusting the locking member 20, the operator can use one hand to hold the handle 23 and the other hand to pinch and push the second end of the body 21 so that the locking buckle 22 fits into the appropriate locking groove 211. This design simplifies the operation and reduces construction time and labor costs. Moreover, the locking buckle 22 is located in the channel defined by the handle 23 and the body 21. The handle 23 can protect the locking buckle 22, preventing external forces from directly acting on it and causing it to disengage from the locking groove 211 or even damage it. Therefore, the handle 23 increases the service life of the locking buckle 22 and improves the overall operational reliability of the cable terminal 100.

[0050] In some embodiments, the outer diameter of the elastic portion 12 gradually decreases and then gradually increases along the direction away from the mating portion 11.

[0051] For example, in Figure 1 , Figure 3 and Figure 4 In the example, along the axial direction of the elastic part 12, the outer diameter at the free end of the elastic part 12 is larger, while the outer diameter at the middle part of the elastic part 12 is smaller, and the elastic part 12 as a whole is roughly in the shape of a "flare". When installing the cable 30, the cable 30 is inserted through the free end of the elastic part 12. Because the outer diameter at the free end of the elastic part 12 is larger, it can guide the insertion of the cable 30, avoiding repeated adjustments to the position of the cable 30 during installation and improving the assembly efficiency of the cable terminal 100. When the cable 30 is installed in the mounting cavity 40, the middle part of the elastic part 12 abuts against and presses the cable 30, so that the cable 30 is reliably fixed in the mounting cavity 40.

[0052] Specifically, each elastic sheet 121 includes a first elastic segment 1211, a second elastic segment 1212, and a third elastic segment 1213 connected in sequence. Multiple first elastic segments 1211 constitute a first sub-elastic portion 122, multiple second elastic segments 1212 constitute a second sub-elastic portion 123, and multiple third elastic segments 1213 constitute a third sub-elastic portion 124. The first sub-elastic portion 122 and the third sub-elastic portion 124 are conical in shape, while the second sub-elastic portion 123 is cylindrical in shape.

[0053] like Figure 1 , Figure 3 and Figure 4 As shown, one end of the first sub-elastic part 122 is connected to the mating part 11, and the other end is connected to the second sub-elastic part 123. The end of the second sub-elastic part 123 away from the first sub-elastic part 122 is connected to the third sub-elastic part 124. When the locking member 20 is installed on the elastic part 12, the locking member 20 is located on the outer periphery of the second sub-elastic part 123. During installation, the third sub-elastic part 124 is tapered, which can guide the insertion of the cable 30, avoiding repeated adjustments to the position of the cable 30 during installation and improving the assembly efficiency of the cable terminal 100. The second sub-elastic part 123 abuts against and presses the cable 30, so that the cable 30 is reliably fixed in the mounting cavity 40. After the cable 30 is installed in the mounting cavity 40, there is a gap between the cable 30 and the first sub-elastic part 122, which prevents the cable 30 from rubbing against the first sub-elastic part 122 during movement and thus avoids damage to the cable 30, improving the service life of the cable 30.

[0054] According to some embodiments of the present invention, the length of the first elastic segment 1211 in the axial direction of the mating part 11 is less than the length of the second elastic segment 1212; and / or the length of the third elastic segment 1213 in the axial direction of the mating part 11 is less than the length of the second elastic segment 1212.

[0055] For example, in Figure 3 and Figure 4 In the example, the lengths of the first elastic segment 1211 and the third elastic segment 1213 are both less than the length of the second elastic segment 1212; or, only the length of the first elastic segment 1211 is less than the length of the second elastic segment 1212 (not shown in the figure); or, only the length of the third elastic segment 1213 is less than the length of the second elastic segment 1212 (not shown in the figure).

[0056] By setting a longer second elastic segment 1212, the contact area between the elastic part 12 and the cable 30 or the locking member 20 is increased, thereby allowing the elastic part 12 to apply force to the cable 30 more evenly. This avoids damage to the cable 30 due to insufficient contact area or excessive pressure, extending the overall service life and long-term stability of the cable terminal 100. Furthermore, the larger contact area between the elastic part 12 and the cable 30 results in greater friction, making the connection between them more secure. This prevents the cable 30 from sliding within the mounting cavity 40, which could lead to connection failure, and improves the operational reliability of the cable terminal 100.

[0057] According to some embodiments of the present invention, the maximum inner diameter of the elastic part 12 is D1, and the minimum inner diameter of the elastic part 12 is D2, wherein D1 and D2 respectively satisfy: 4mm≤D1≤5.5mm, 2mm≤D2≤2.5mm.

[0058] When D1 < 4mm, the maximum inner diameter of the elastic part 12 is too small, meaning the inner diameter of the free end of the elastic part 12 or the connection between the elastic part 12 and the mating part 11 is too small. This fails to guide the insertion of the cable 30, requiring repeated adjustments to the cable 30 position during installation and reducing the assembly efficiency of the cable terminal 100. When D1 > 5.5mm, the maximum inner diameter of the elastic part 12 is too large, meaning the inner diameter of the free end of the elastic part 12 or the connection between the elastic part 12 and the mating part 11 is too large. This results in an excessively large overall volume of the elastic part 12, increasing material costs and weight, which is detrimental to the lightweight design of the elastic part 12. Therefore, by setting the maximum inner diameter D1 of the elastic part 12 within the range of 4mm to 5.5mm, both the assembly efficiency of the cable terminal 100 and the lightweight design of the elastic part 12 are improved.

[0059] When D2 < 2mm, the minimum inner diameter of the elastic part 12 is too small, meaning the inner diameter at the crimping point between the elastic part 12 and the cable 30 is too small. This may cause the cable 30 to "get stuck" during assembly, making installation difficult and potentially damaging the cable 30. When D2 > 2.5mm, the minimum inner diameter of the elastic part 12 is too large, meaning the inner diameter at the crimping point between the elastic part 12 and the cable 30 is too large. When the elastic part 12 switches from the unlocked state to the locked state, it may exceed its elastic deformation limit, and the elastic part 12 may still not properly press the cable 30, affecting the normal use of the cable terminal 100. Therefore, by setting the minimum inner diameter D2 of the elastic part 12 within the range of 2mm to 2.5mm, the assembly success rate of the cable terminal 100 and the service life of the cable 30 are improved, as is the operational reliability of the cable terminal 100.

[0060] In some embodiments, the connector 10 includes a first connector 13 and a second connector 14 that are plugged into each other. The mating portion 11 of the first connector 13 is generally cylindrical. The mating portion 11 of the second connector 14 includes a plug-in section 141. During installation, the plug-in section 141 of the second connector 14 is inserted into the first connector 13 along the axial direction of the first connector 13, so that the first connector 13 and the second connector 14 are coaxially arranged.

[0061] The connector 200 according to a second aspect embodiment of the present invention includes the cable terminal 100 according to the first aspect embodiment of the present invention described above.

[0062] According to the present invention, the connector 200, by adopting the above-mentioned cable terminal 100, eliminates the need for additional tools to apply pressure, reduces the reliance on professional tools and operator skills, simplifies the operation steps, thereby reducing construction time and labor costs, avoids incomplete crimping or terminal damage due to operator errors during the crimping process, and improves the electrical performance and stability of the connector 200.

[0063] In some embodiments, the connector 200 further includes a connector body 50, which includes a positive electrode body 51 and a negative electrode body 52. ​​The positive electrode body 51 and the negative electrode body 52 are inserted into each other, and the positive electrode body 51 and the negative electrode body 52 together define a receiving cavity 53, in which a cable terminal 100 is fitted. During assembly, the operator first connects the cable terminal 100, then installs the cable terminal 100 on one of the positive electrode body 51 and the negative electrode body 52, and then inserts the positive electrode body 51 and the negative electrode body 52 into each other.

[0064] According to some embodiments of this utility model, such as Figure 6 and Figure 7 The connector 200 also includes a seal 60 disposed between the positive electrode body 51 and the negative electrode body 52.

[0065] For example, in Figure 7 In the example, an annular groove 511 is formed on the positive electrode body 51, and the sealing element 60 adopts a sealing ring. The setting of the sealing element 60 makes the connection between the positive electrode body 51 and the negative electrode body 52 more reliable and improves the sealing performance between the positive electrode body 51 and the negative electrode body 52, thereby improving the working reliability and long-term stability of the connector 200.

[0066] Specifically, a first step portion 521 is formed on the positive electrode body 51 and / or the negative electrode body 52, and the connector 200 also includes at least one first sealing member 70, which engages at the first step portion 521.

[0067] like Figure 7 and Figure 8 As shown, both the positive electrode body 51 and the negative electrode body 52 have a first step portion 521 formed on them. There can be two first sealing members 70. The first sealing member 70 has a through hole. When the cable terminal 100 is installed in the receiving cavity 53, the first sealing member 70 is passed through the cable 30 and abuts against the corresponding first step portion 521. Since the cable 30 is relatively long, the first sealing member 70 can fix the position of the cable 30 away from the connector 10, prevent the cable 30 from shaking in the receiving cavity 53, and improve the long-term stability of the connector 200.

[0068] According to some embodiments of the present invention, a second step portion 71 is formed in the circumferential direction of the first sealing member 70, and the connector 200 further includes at least one second sealing member 80, which cooperates with the second step portion 71 and the positive electrode body 51 or the negative electrode body 52.

[0069] like Figure 7 As shown, the second step portion 71 is located at the axial end of the first sealing member 70 away from the connector 10. The transition of the second step portion 71 is approximately flush with the corresponding positive electrode body 51 or negative electrode body 52. ​​The second sealing member 80 is located on the outer periphery of the first sealing member 70, and one axial end of the second sealing member 80 abuts against the second step portion 71 and the corresponding positive electrode body 51 or negative electrode body 52 to prevent the first sealing member 70 from sliding in its axial direction. Therefore, the first sealing member 70 and the second sealing member 80 work together to increase the reliability of fixing the cable 30, thereby improving the long-term stability of the connector 200.

[0070] In some embodiments, a threaded portion 512 is formed on the positive electrode body 51 and / or the negative electrode body 52, and the connector 200 further includes at least one threaded element 90, which is threadedly connected to the threaded portion 512.

[0071] like Figure 7 As shown, there can be two threaded components 90. These two threaded components 90 are respectively connected to the threaded portions 512 on the positive electrode body 51 and the negative electrode body 52. ​​The threaded components 90 adopt a hollow nut structure, allowing the cable 30 to pass through them. After the first sealing component 70 and the second sealing component 80 are both installed, the threaded components 90 are connected to their corresponding threaded portions 512 to complete the overall installation of the connector 200. The threaded connection method is more reliable and easier to install, improving the long-term stability and installation efficiency of the connector 200.

[0072] A photovoltaic module (not shown) according to a third aspect embodiment of the present invention includes a connector 200 according to the second aspect embodiment of the present invention described above.

[0073] The photovoltaic module according to the present invention, by adopting the above-mentioned connector 200, simplifies the operation steps, thereby reducing construction time and labor costs, and improving the electrical performance and stability of the photovoltaic module.

[0074] Other components and operations of the photovoltaic modules according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0075] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, 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, and therefore should not be construed as a limitation of this utility model.
