[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0046] This application provides a connection terminal 1, see Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the overall structure of the connection terminal 1 provided in an exemplary embodiment of the present disclosure, Figure 2 is an end view of the connection terminal 1 provided in the exemplary embodiment of the present disclosure.

[0047] The connecting terminal 1 includes a main body 11 and a clamping group. The clamping group includes two clamping springs 13 arranged opposite to each other. One end of the clamping spring 13 is connected to the main body 11, and the other end of the clamping spring 13 is a clamping portion 131. The clamping portions 131 of the two clamping springs 13 are arranged close to each other. The distance between the clamping portions 131 of the two clamping springs 13 is a clamping gap 14. There are multiple clamping groups, and the multiple clamping groups are arranged at intervals, and the distances of the clamping gaps 14 of at least some of the clamping groups are different.

[0048] The plurality of clamping groups may be arranged side by side, in a matrix, or spaced apart along an arc. The specific implementation method may be adapted according to the actual application scenario.

[0049] In addition, the clamping spring piece 13 can be integrally formed with the main body 11 , or can be welded to the main body 11 .

[0050] It can be understood that when the distance between the two clamping springs 13 in each clamping group and one end connected to the main body 11 is large, the distance between the two clamping springs 13 gradually decreases from the direction close to the clamping portion 131 until a clamping gap 14 is formed for clamping the male terminal, wherein the male terminal can be a contact pin.

[0051] Correspondingly, when the distance between the two clamping springs 13 in each clamping group and one end connected to the main body 11 is small, the distance between the two clamping springs 13 gradually increases and then gradually decreases from the direction approaching the clamping portion 131 until a clamping gap 14 is formed for clamping the male terminal, thereby providing a suitable elastic abutment force for clamping the male terminal.

[0052] Specifically, take the example that the connecting terminal 1 includes two clamping groups, such as Figure 2 As shown, the spacing between the clamping parts 131 of one clamping group is X1, and the spacing between the clamping parts 131 of the other clamping group is X2. The clamping group with the spacing X1 clamps male terminals of a first thickness specification whose thickness matches the spacing, and the clamping group with the spacing X2 clamps male terminals of a second thickness specification whose thickness matches the spacing.

[0053] It can be understood that the spacing X1 and the spacing X2 can be adjusted according to the application scenario of the connecting terminal 1, so that the connecting terminal 1 can clamp the male terminal in the corresponding application scenario, and avoid the deformation of the clamping spring 13 exceeding its elastic deformation and causing plastic deformation.

[0054] In this embodiment, by providing multiple clamping groups and making the clamping gaps 14 of at least some of the clamping groups different in size, the connection terminal 1 can clamp male terminals of various thickness specifications. In this way, not only the cost of the connection terminal 1 can be controlled, but also the related development costs can be controlled.

[0055] In addition, by enabling one connecting terminal 1 to clamp male terminals of various thickness specifications, compared with the need to configure connecting terminals 1 of various specifications, the installation steps of the remaining connecting terminals 1 are omitted, thereby improving the installation efficiency.

[0056] See also Figure 1 In some embodiments, the main body 11 includes a sleeve 11 a, and the clamping group is located on the inner circumference of the sleeve 11 a.

[0057] In this embodiment, by arranging the clamping group on the inner circumference of the sleeve 11a, the sleeve 11a can provide protection for the connection portion between the connecting terminal 1 and the male terminal, thereby improving the reliability of the connection between the connecting terminal 1 and the male terminal.

[0058] See also Figure 2 In some embodiments, a plurality of clamping groups are sequentially arranged along a first direction, and two clamping springs 13 of each clamping group are respectively located on both sides of the first direction, and the first direction is perpendicular to the axis of the sleeve 11a.

[0059] It can be understood that, since the sizes of the clamping gaps 14 of at least some clamping groups are different, the spacings between the clamping portions 131 of at least some of the clamping springs 13 on the same side of the first direction and the first direction are different.

[0060] In this way, a clamping spring piece 13 located on one side of the first direction and closest to the first direction and a clamping spring piece 13 located on the other side of the first direction and closest to the first direction can be used as a pair of clamping groups, which can be used as the clamping portion 131 of the male terminal of the third thickness specification, thereby further improving the applicability of the connecting terminal 1.

[0061] Specifically, take the example that the connecting terminal 1 includes two clamping groups, such as Figure 3 As shown, Figure 3 1 is an end view of another connection terminal 1 provided in an exemplary embodiment of the present disclosure. The distance between the two clamping springs 13 closest to the first direction is X3, and the two clamping springs 13 forming the distance X3 can clamp the male terminal of the third thickness specification whose thickness is adapted to the distance. It can be understood that the width of the male terminal of the third thickness specification is larger so that it can contact with the two clamping springs 13 formed with the distance X3.

[0062] in addition, Figure 3 In the embodiment, the spacing between the other two clamping springs 13 is X4, and the spacing X3 and the spacing X4 can also be adjusted according to the application scenario of the connecting terminal 1.

[0063] In addition, in this embodiment, through the above arrangement, the layout of the plurality of clamping groups is also regular, which is beneficial to improving the structural compactness of the connecting terminal 1 and further beneficial to controlling the overall size of the connecting terminal 1 .

[0064] See also Figure 4 and Figure 5 , Figure 4 is a top view of a connection terminal 1 provided in an exemplary embodiment of the present disclosure, Figure 5 yes Figure 4 AA cross-sectional view. In some embodiments, the sleeve 11a is formed by winding a metal sheet. Along the circumferential direction of the winding. The sleeve 11a has an inner end 115 close to the winding axis. The inner end 115 is provided with an intermediate plate 111 extending along the first direction. Along the first direction, the clamping springs 13 located on one side of the first direction and arranged in an odd sequence are connected to the intermediate plate 111, and the clamping springs 13 located on the other side of the first direction and arranged in an even sequence are connected to the intermediate plate 111, and the remaining clamping springs 13 are connected to the barrel wall adjacent to it on the sleeve 11a.

[0065] Specifically, the sleeve 11a is formed by bending a metal sheet. Before bending, each clamping spring piece 13 can be punched out from the technical sheet by a punching process.

[0066] The clamping springs 13 connected to the middle plate 111 are middle clamping springs 132, and the remaining clamping springs 13 are side clamping springs 133. The middle clamping springs 132 are respectively arranged in a one-to-one correspondence with the side clamping springs 133, that is, each clamping group includes a middle clamping spring 132 and a side clamping spring 133. The distance between the middle clamping spring 132 and the plane where the middle plate 111 is located increases first and then decreases, such as Figure 6 As shown, Figure 6 yes Figure 4 The portion where the distance between the intermediate clamping spring piece 132 and the plane where the intermediate plate 111 is located is smaller is the clamping portion 131 of the intermediate clamping spring piece 132. Correspondingly, the edge clamping spring piece 133 is extended from the cylinder wall to the clamping portion 131 of the intermediate clamping spring piece 132 corresponding thereto.

[0067] It can be understood that the middle clamping spring piece 132 is formed by bending the plane where the middle plate 111 is located to form a structure opposite to the edge clamping spring piece 133. Therefore, the middle clamping spring piece 132 has a tendency to move toward the plane where the middle plate 111 is located. When the connecting terminal 1 clamps the male terminal, the male terminal is located on the side where the middle clamping spring piece 132 moves toward the plane where the first plate is located. In this way, the movement tendency makes the clamping force of the middle clamping spring piece 132 on the male terminal greater, so that the middle clamping spring piece 132 can stably elastically abut against the male terminal, thereby improving the reliability of the connecting terminal 1 clamping the male terminal.

[0068] In addition, by setting the sleeve 11a as a winding structure, the clamping spring piece 13 located in the sleeve 11a can be integrally formed with the sleeve 11a, thereby improving the molding efficiency and simplifying the molding difficulty, and improving the stress condition of the connection part between the clamping spring piece 13 and the sleeve 11a, so as to improve the structural stability of the connecting terminal 1.

[0069] See also Figure 5 In some embodiments, the sleeve 11a has two oppositely disposed first inner walls 112. The first inner walls 112 are parallel to the middle plate 111. The distance between the middle plate 111 and the two first inner walls 112 is consistent.

[0070] In this embodiment, through the above arrangement, the structure of the connection terminal 1 can be made more symmetrical, and the layout of the clamping springs 13 can be made more uniform, thereby improving the stress condition inside the connection terminal 1 and enhancing the reliability of the connection terminal 1.

[0071] See also Figure 7 , Figure 7 yes Figure 1 In some embodiments, the remaining clamping springs 13 are formed by punching and bending the metal sheet of the forming sleeve 11a.

[0072] In this embodiment, through the above-mentioned arrangement, on the one hand, the assembly cost of connecting the remaining clamping springs 13 with the sleeve 11a can be reduced, and the punching and bending forming method is simple and the production efficiency is high; on the other hand, it can avoid the existence of large stress in the connection part between the clamping spring 13 and the sleeve 11a, thereby improving the stress state of the connection part between the clamping spring 13 and the sleeve 11a.

[0073] See also Figure 8 and Fig. 9 , Figure 8 is a schematic diagram of the overall structure of the connection terminal 1 provided in another viewing direction in an exemplary embodiment of the present disclosure, Fig. 9 yes Figure 8 Enlarged view of point C in the middle. In some embodiments, a first plug-in portion 113 is protruded from one side of the middle plate 111 away from the inner end 115 , and an opening 114 is provided on the wall of the sleeve 11a opposite to the first plug-in portion 113 , and the first plug-in portion 113 matches the opening 114 .

[0074] It is understandable that, before being wound into the sleeve 11 a , the first plug-in portion 113 and the opening 114 may be punched out on the metal sheet 2 used for forming the sleeve 11 a .

[0075] Specifically, the opening 114 is disposed on a side of the sleeve 11 a away from the clamping portion 131 .

[0076] In this embodiment, by providing the first plug-in portion 113 to cooperate with the opening 114, the sleeve 11a can support the suspended end of the middle plate 111, thereby improving the overall strength of the connection terminal 1 in a direction perpendicular to the middle plate 111, so as to prevent the displacement of the clamping spring 13 connected to the middle plate 111. In this way, the structural reliability of the connection terminal 1 can be improved.

[0077] See also Figure 2 In some embodiments, along the circumferential direction of the winding, the sleeve 11a has an outer end 116 away from the winding axis. The end of the first plug-in portion 113 away from the middle plate 111 passes through the opening 114 and contacts the outer end 116. In this way, not only the portion of the sleeve 11a with the opening 114 supports the first plug-in portion 113, but also the outer end 116 of the sleeve 11a supports the first plug-in portion 113, thereby improving the support of the sleeve 11a to the suspended end of the middle plate 111, and further improving the overall strength of the connection terminal 1 in the direction perpendicular to the middle plate 111.

[0078] In addition, by passing the end of the first plug-in portion 113 away from the middle plate 111 through the opening 114 and contacting the outer end 116, it is also convenient to directly judge the matching condition of the first plug-in portion 113 and the opening 114 by observation after the sleeve 11a is wound.

[0079] See also Fig.10 , Fig.10 yes Figure 1 In some embodiments, at least one wall of the sleeve 11a includes an inner layer and an outer layer stacked in the radial direction thereof, and the outer layer is provided with a first plug-in structure 117. The inner layer is provided with a second plug-in structure 118. The first plug-in structure 117 is plugged with the second plug-in structure 118.

[0080] It can be understood that the outer wall is used to shape the outer circumference of the sleeve 11a, and the inner wall is the part wrapped by the outer wall. Therefore, when the sleeve 11a is wound from a metal sheet 2, along the circumferential direction of the winding, one part of the sleeve 11a is the inner wall, and the other part is the outer wall.

[0081] In addition, one of the first plug-in structure 117 and the second plug-in structure 118 is a hole body or a slot body, and the other is an insert block or an insert plate.

[0082] In this embodiment, by providing the first plug-in structure 117 and the second plug-in structure 118 for plugging, the inner wall and the outer wall of the sleeve 11a can support and limit each other, thereby improving the overall strength of the connection terminal 1 and further improving the structural reliability of the connection terminal 1.

[0083] Specifically, the first plug structure 117 and the second plug structure 118 are plugged into the first supporting part, the first plug part 113 and the opening 114 are the second supporting part, and along the first direction, the first supporting part and the second supporting part are respectively located on both sides of the sleeve 11a. In this way, the structural symmetry of the connecting terminal 1 can be improved to improve its stress state, and the strength distribution of the connecting terminal 1 can be uniform, thereby improving the structural stability of the connecting terminal 1.

[0084] See also Fig.10 In some embodiments, the first plug-in structure 117 is a limiting hole. The second plug-in structure 118 is a plug-in sheet. One end of the plug-in sheet passes through the limiting hole and extends to the outside of the sleeve 11a.

[0085] It can be understood that after the connection terminal 1 is formed, a sheath needs to be sheathed on the outside to insulate its non-electrical connection part from the outside.

[0086] Based on this, in this embodiment, one end of the plug piece passes through the limiting hole and is located outside the sleeve 11a, so that the connection terminal 1 can be prevented from being installed reversely when it is matched with the sleeve. In this way, the smoothness and efficiency of the assembly of the connection terminal 1 and the sleeve can be improved.

[0087] In addition, in this embodiment, by passing one end of the plug-in piece through the limiting hole and then being located outside the sleeve 11a, it is convenient to directly judge the matching condition of the plug-in piece and the limiting hole by observation after the sleeve 11a is rolled and formed.

[0088] See also Figure 1 In some embodiments, along the winding axis, the sleeve 11a has a first end close to the clamping portion 131. The first end is extended to have a guide flange 119. The guide flange 119 is located inside the sleeve 11a.

[0089] It can be understood that the guide flange 119 is an arc structure, which is integrally formed with the sleeve 11 a.

[0090] In this embodiment, by providing the guide flange 119, a guiding effect can be played during the plugging process between the connecting terminal 1 and the male terminal, thereby improving the plugging efficiency and smoothness.

[0091] See also Figure 8 At least one wall of the sleeve 11a includes an inner layer and an outer layer stacked in a radial direction, and the outer layer is welded to the inner layer.

[0092] Specifically, a portion of the sleeve 11a close to the outer end 116 is spot welded to the inner ring of the sleeve 11a adjacent thereto. Figure 8 The dots shown in the figure are solder points.

[0093] In this embodiment, through the above arrangement, on the one hand, the outer end 116 of the sleeve 11a can be fixed, thereby improving the structural stability of the connecting terminal 1; on the other hand, the overall structural strength of the connecting terminal 1 can be improved, thereby improving the reliability of the connecting terminal 1.

[0094] See also Figure 2 and Figure 6 In some embodiments, the connection terminal 1 further includes a limiting piece 120. One end of the limiting piece 120 is connected to the sleeve 11a, and the other end extends to a side of at least one clamping spring piece 13 connected to the middle plate 111 close to the first direction.

[0095] The limiting piece 120 is formed by punching and bending the metal plate of the forming sleeve 11 a.

[0096] It can be understood that the clamping spring 13 connected to the middle plate 111 is the middle clamping spring 132, which is formed by bending the plane where the middle plate 111 is located to form a structure opposite to the edge clamping spring 133. Therefore, the middle clamping spring 132 has a tendency to move toward the plane where the middle plate 111 is located.

[0097] Based on this, in this embodiment, by setting a limit plate 120, the tendency of the clamping spring 13 connected to the middle plate 111 to move toward the plane where the middle plate 111 is located is restricted, so as to ensure the minimum clamping distance between the two clamping springs 13 of the clamping group, thereby facilitating the smoothness of inserting the male terminal into the clamping group, and further improving the ease of operation of the male terminal and the connecting end.

[0098] Specifically, take the example that the connecting terminal 1 includes two clamping groups, such as Figure 2 As shown, there are two limit plates 120 and two clamping springs 13 connected to the middle plate 111. The two limit plates 120 are arranged facing each other along the first direction. The two limit plates 120 are respectively located on one side of the two clamping springs 13 connected to the middle plate 111 close to the first direction.

[0099] See also Figure 6 In some embodiments, a guide portion 134 is provided at the end of the clamping portion 131. In a direction away from the clamping portion 131, the distance between the two guide portions 134 of the clamping group gradually increases.

[0100] In this embodiment, by providing the guide portion 134 , the docking between the male terminal and the clamping assembly can be guided, thereby improving the smoothness of the docking between the connecting terminal 1 and the male terminal.

[0101] See also Figure 6In some embodiments, a hook portion 135 is disposed at the end of the guide portion 134, one end of the hook portion 135 is connected to the guide portion 134, and the other end extends toward the clamping portion 131, and the two hook portions 135 of each clamping group are disposed back to back.

[0102] In this embodiment, by providing the bent hook portion 135 , the tip of the clamping spring sheet 13 can be prevented from contacting the male terminal, thereby preventing the male terminal from being scratched by the clamping spring sheet 13 , thereby protecting the surface quality of the male terminal.

[0103] In some embodiments, the clamping spring piece 13 has a width dimension, and the width of the clamping spring piece 13 gradually decreases in a direction away from a connection portion between the clamping spring piece 13 and the main body 11 .

[0104] It can be understood that the width direction of the clamping spring piece 13 is parallel to the first direction.

[0105] In this embodiment, through the above-mentioned arrangement, the clamping spring piece 13 has both a suitable mating surface for electrical connection with the male terminal and a larger portion for connection with the main body 11, thereby improving the strength of the connection portion between the clamping spring piece 13 and the main body 11, thereby improving the overall structural reliability of the connecting terminal 1.

[0106] On the basis of the above embodiments, taking the example that the connecting terminal 1 includes two clamping groups, the connecting terminal 1 is further described through the following contents.

[0107] like Fig.11 As shown, Fig.11 1 is a schematic layout diagram of the connection terminal 1 provided in an exemplary embodiment of the present disclosure in a state of being in a material-expanding state.
