The term "based on" is "based at least in part on." The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment," and so on.

[0037] Figure 1 A structural diagram of the conductive sheet 100 is shown, which is used in cooperation with one embodiment of the present application. The conductive sheet 100 can be located on a fan housing. In the field of electromechanical devices, a fan can be used for ventilation, dust removal, cooling, etc. The size of the conductive sheet 100 can be in the order of millimeters. The middle of the conductive sheet 100 can include a through hole 101, which can be used for inserting a wire and providing a soldered connection between the wire and the conductive sheet.

[0038] The size of the conductive terminal in the related art is usually in the order of centimeters, and due to the space structure limitation around the conductive sheet, such a conductive terminal cannot meet the application requirements. TE-06640(I)

[0039] The present application mainly focuses on the following technical problem: how to provide a solder-free and small-size conductive terminal.

[0040] In order to solve the above problems, according to one general idea of the present application, a conductive terminal is provided, comprising: a clamping part configured to clamp a wire; and a receiving part configured to be insertedly connected with a conductive sheet, comprising four side walls arranged around with respect to the insertion direction; wherein the clamping part extends from the middle of one side wall of the receiving part, and the wire extension direction of the clamping part is perpendicular to the insertion direction of the receiving part.

[0041] Figure 2a A structural diagram of the conductive terminal 200 of one embodiment of the present application is shown. Figure 2b is a top view of the conductive terminal 200. Figure 2c is a diagram showing the structure of the rear of the conductive terminal 200. As shown in Figures 2a-2c The conductive terminal 200 includes a clamping part 210 and a receiving part 220. The clamping part 210 is configured to clamp a wire. The receiving part 220 is configured to be insertedly connected with a conductive sheet 100. The shape of the receiving part 220 is a box body, which includes four side walls 221, 222, 223, 224 arranged around with respect to the insertion direction. Please refer to Figure 2cThe clamping portion 210 extends from the middle of one side wall 224 of the receiving portion 220. The wire extension direction of the clamping portion 210 is perpendicular to the insertion direction of the receiving portion 220. The left wall 221 and the right wall 223 correspond to the thickness direction of the conductive sheet, i.e., parallel to the thickness direction. The front wall 222 and the rear wall 224 correspond to the width direction of the conductive sheet, i.e., parallel to the width direction. Here, front and rear refer to two directions in the thickness direction of the conductive sheet, and left and right refer to two directions in the width direction of the conductive sheet.

[0042] The receiving portion 220 can be inserted into connection with the conductive sheet 100 in a fixed position along the insertion direction. The insertion connection of the receiving portion 220 with the conductive sheet 100 can clamp the periphery of the conductive sheet 100. In addition, since the wire extension direction of the clamping portion is perpendicular to the insertion direction of the receiving portion, i.e., the conductive terminal is in a flag type structure, it is beneficial to be applied to the case where the space around the conductive terminal is limited.

[0043] In some examples, the four side walls of the receiving portion can include protruding portions protruding inwardly of the receiving portion. As shown in Figures 2a-2e The four side walls include protruding portions 221a, 222a, 223a, 224a protruding inwardly of the box. The protruding portion on each side wall can be located at the middle position of the side wall. The protruding portion can provide a positive holding force between the conductive terminal and the conductive sheet to clamp the periphery of the conductive sheet 100. In this way, when the conductive sheet 100 is small in size (for example, the length, width and height are 2mm, 0.5mm and 3mm respectively), the conductive terminal can still clamp the conductive sheet from all around to ensure connection.

[0044] It can be understood that in other examples, the relative positions of the clamping portion and the receiving portion can be flexibly adjusted in the case where the space is limited. For example, the clamping portion 210 is located above the receiving portion 220, i.e., the side wall 224 is formed vertically and extended from the clamping portion 210, and then the other three side walls are bent to finally form the receiving portion 220. The receiving portion 220.

[0045] In some examples, the protruding portion on the side wall can include a spring piece, which can be formed by stamping. Referring to Figures 2a-2c The side wall 221 and the side wall 222, the side wall 222 and the side wall 223, and the side wall 223 and the side wall 224 can be stamped and cut, and four spring pieces can be formed at the middle positions of the four side walls along the thickness direction of the metal sheet. The structure of the spring piece can press the surface of the conductive sheet to form a holding force.

[0046] The spring piece not only can press the conductive sheet, but also can play a guiding role. For example, referring to Figure 2bThe protruding portions 221a and 223a are in a spring structure, and during the process of inserting the receiving portion 220 into the conductive sheet 100, the protruding portions 221a and 223a can guide the receiving portion 220 to be inserted around the conductive sheet 100, thereby improving the connection efficiency.

[0047] In some examples, the protruding portions of the front wall and / or the rear wall can include a bump structure. The bump structure can cooperate with the through hole 101 of the conductive sheet 100, and when the receiving portion 220 is connected with the conductive sheet 100, the bump structure can be snap-connected with the through hole 101.

[0048] In some examples, the protruding portions of one side wall of the front wall and / or the rear wall include a bump structure, and the protruding portions of the other side wall are in a spring structure. For example, referring to Figures 2b-2e The protruding portion 224a includes a spring and a bump structure 224b on the spring, and the protruding portions 221a, 222a and 223a are in a spring structure. Figure 2d and Figure 2e The longitudinal sectional views of the receiving portion 220 are shown from the front and rear perspectives. The bump structure 224b is located on the rear wall 224 corresponding to the position of the through hole 101. During the process of inserting the receiving portion 220 into the conductive sheet 100, the protruding portions 221a, 222a, 223a and 224a are all deformed under pressure, and when they travel to the through hole 101, the bump structure 224b is snap-connected with the through hole 101. In this way, when the conductive terminal 200 is connected with the conductive sheet 100, the protruding portions on the four side walls not only press around the conductive sheet 100 in the insertion direction, but also the bump structure 224b snap-connected with the through hole 101 can resist external vibration in the insertion direction, thereby improving the reliability of the connection between the conductive terminal and the conductive sheet.

[0049] It can be understood that although in the example of Figures 2a-2e the bump structure 224b is located on the rear wall 224, in other examples, the bump structure can be located on the front wall, for example, the protruding portion 222a of the front wall 222 also includes a bump structure. In addition, in some examples, the protruding portions 222a and 224a can both include a spring and a bump structure on the spring, thereby further improving the connection stability.

[0050] In some examples, the conductive terminal 200 can be integrally formed, i.e. the clamping portion 210 and the receiving portion 220 are integrally formed. The conductive terminal 200 can be formed by stamping, bending, etc. from a whole metal sheet. Now referring to Figure 2c The conductive terminal 200 further includes a connecting portion 230 located between the clamping portion 210 and the receiving portion 220. The receiving portion 220 can extend along the bending portion 230 and be bent to form a box. The box is combined at the left wall 221. The middle of the left wall is a protruding portion 221a, and the two ends are combined portions 221b. The combined portions 221b are interlaced dovetail structures, which can improve the stability of the conductive terminal.

[0051] It can be understood that Figures 2c-2d The shape of the bump structure 224b on the receiving portion 220 is only an example, and can also be any other suitable shape.

[0052] According to Figures 2a-2c , the clamping portion 210 is located on the left side of the receiving portion 220. It can be understood that in some examples, the clamping portion 210 can also be located on the right side of the receiving portion 220. In addition, the clamping portion 210 can also extend from the middle of the other side wall of the receiving portion 220, which is not limited to Figures 2a-2c Examples. In addition, the bending angle between the clamping portion 210 and the receiving portion 220 can be flexibly set to adapt to the space where the conductive sheet is located.

[0053] The size of the box of the receiving portion can match the size of the conductive sheet. For example, for a conductive sheet with a height of 3mm and a width of 2mm, the height of the box can be no more than 3mm, and the width of the internal space of the box can be no more than 2mm.

[0054] As shown in Figures 2a-2c , the clamping portion 210 includes a wire shell connecting portion 211 and a wire core connecting portion 212. The center lines of the wire shell connecting portion 211 and the wire core connecting portion 212 can be located on the same straight line, and the wire core connecting portion 212 is closer to the receiving portion 220 than the wire shell connecting portion 211. The wire core connecting portion 212 is used to fix and connect the exposed wire core of the cable (not shown), and the wire shell connecting portion 211 is used to fix the wire shell of the cable. In some examples, the inner side surface of the wire core connecting portion 212 is provided with a protruding transverse line for pressing the exposed wire core.

[0055] The conductive terminal 200 is a flag type structure. In other examples, the conductive terminal can adopt a straight line type structure. For example, the center lines of the wire core connecting portion 212, the wire shell connecting portion 211 and the receiving portion 220 are located on the same straight line.

[0056] Figure 3a The structure schematic diagram of the conductive terminal 300 of one embodiment of the present application is shown. Figure 3b is a top view of the conductive terminal 300. Figure 3c is a schematic diagram showing the rear structure of the conductive terminal 300. The difference between the conductive terminal 300 and the conductive terminal 200 is that the rear wall of the receiving portion is different. The differences between the two are discussed below, and the same parts will not be described again.

[0057] According toFigures 3a-3c The protruding portions of the left wall 321, the right wall 323, and the front wall 322 are all spring pieces, while the protruding portion of the rear wall 324 does not include a spring piece but is only a bump structure 324b on the rear wall. Figure 3d A longitudinal sectional view of the receiving portion 320 is shown from a front view angle.

[0058] The bump structure 324b is located on the rear wall 324 at a position corresponding to the through hole 101. In the receiving portion 320TE-06640(I) During the process of inserting the conductive sheet 100, the protruding portions 221a, 222a, 223a3 are all deformed under pressure, and when advancing to the through hole 101, the bump structure 324b is clamped with the through hole 101. In this way, when the conductive terminal 300 is connected with the conductive sheet 100, the protruding portions on the three side walls press the conductive sheet 100, and the bump structure 324b clamped with the through hole 101 can resist external vibration in the insertion direction.

[0059] It can be understood that, although in the example of the conductive terminal 200, the bump structure 324b is located on the rear wall 324, in other examples, the bump structure can be located on the front wall, for example, the protruding portion of the front wall 322 is a bump structure, and the protruding portion of the rear wall 324 is a spring piece. In addition, in some examples, the protruding portions 322a, 324a can all be bump structures, so that the connection stability can be further improved. Figures 3a-3d

[0060] In the conductive terminal 300, since it is not necessary to punch a spring piece on the rear wall 324, but only to punch the bump structure 324b, the manufacturing process can be simplified.

[0061] Figure 4a A structure schematic diagram of a conductive terminal 400 of an embodiment of the present application is shown. Figure 4b is a top view of the conductive terminal 400. Figure 4c is a schematic diagram showing the rear structure of the conductive terminal 400. The difference between the conductive terminal 400 and the conductive terminals 200, 300 is that the conductive terminal does not include a bump structure. The differences from the conductive terminals 200, 300 are discussed below, and the same parts are not described again.

[0062] According to Figures 4a-4c The protruding portions of the left wall 421, the right wall 423, the front wall 422, and the rear wall 424 are all spring pieces. Figure 4d A longitudinal sectional view of the receiving portion 420 is shown from a front view angle.

[0063] ​When the conductive terminal 400 is used in cooperation with the conductive sheet 100, the elastic sheets 421a, 422a, 423a, 424a are deformed under pressure during the process of inserting the conductive sheet 100 into the receiving portion 420. When the conductive terminal 400 is connected with the conductive sheet 100, the protruding portions on the four side walls press the periphery of the conductive sheet 100 around the insertion direction.

[0064] In other examples, the conductive terminal 400 can also be used in cooperation with a conductive sheet without a through hole. For example, Figure 5 A structural diagram of a conductive sheet 500 used in cooperation with one embodiment of the present application is shown. The conductive sheet 500 has recesses 511 on both sides. The recesses 511 can be snap-fit connected with the conductive terminal 400.

[0065] When the conductive terminal 400 is used in cooperation with the conductive sheet 500, the elastic sheets 421a, 422a, 423a, 424a are deformed under pressure during the process of inserting the conductive sheet 500 into the receiving portion 420. When the elastic sheets 421a, 423a snap into the recesses 511 when advancing to the recesses 511. In this way, when the conductive terminal 400 is connected with the conductive sheet 500, the protruding portions on the four side walls not only press the periphery of the conductive sheet 500 around the insertion direction, but also the elastic sheets on the left and right side walls can resist external vibration in the insertion direction, thereby improving the reliability of the connection between the conductive terminal and the conductive sheet. TE-06640(I)

The conductive terminal can be any of the conductive terminals described above. The conductive sheet can include a through hole structure and / or recesses on both sides. The through hole structure and the recesses can be configured to be snap-fit connected with the conductive terminal.
