[0035] The technical solutions of the present utility model will be further specifically described below through embodiments in conjunction with the accompanying drawings. In the specification, the same or similar reference numerals indicate the same or similar components. The description of the embodiments of the present utility model with reference to the accompanying drawings is intended to explain the overall inventive concept of the present utility model, and should not be construed as a limitation to the present utility model.

[0036] As used herein, the terms "comprising", "including" and similar terms shall be construed as open-ended terms, i.e., "including but not limited to", indicating that other elements may also be included. The term "based on" means "at least partially based 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 The structural schematic diagram of the conductive sheet 100 used in cooperation with one embodiment of the present utility model is shown. The conductive sheet 100 can be located on the blower housing. In the field of electromechanical equipment, blowers can be used for ventilation, dust removal, cooling and other purposes. The size of the conductive sheet 100 can be at the millimeter level. The middle of the conductive sheet 100 can include a through hole 101, and the through hole 101 can be used for inserting a wire and welding to connect the wire and the conductive sheet.

[0038] In the related art, the size of the conductive terminal is usually at the centimeter level. Due to the spatial structure limitation around the conductive sheet, such conductive terminals cannot meet the application requirements.

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

[0040] To solve the above problems, according to a general concept of the present utility model, a conductive terminal is provided, including: a clamping portion configured to clamp and connect a wire; and a receiving portion configured to be inserted and connected to a conductive sheet, including four side walls arranged around the insertion direction; wherein, the clamping portion extends from the middle of one side wall of the receiving portion, and the wire extending direction of the clamping portion is perpendicular to the insertion direction of the receiving portion.

[0041] Figure 2a The structural schematic diagram of the conductive terminal 200 of one embodiment of the present utility model is shown. Figure 2b It is a top view of the conductive terminal 200. Figure 2c It is a schematic diagram showing the rear structure of the conductive terminal 200. As Figures 2a - 2c shown, the conductive terminal 200 includes a clamping portion 210 and a receiving portion 220. The clamping portion 210 is configured to clamp and connect a wire. The receiving portion 220 is configured to be inserted and connected to the conductive sheet 100. The shape of the receiving portion 220 is a box, and the box includes four side walls 221, 222, 223, 224 arranged around the insertion direction. Reference can be made to Figure 2c, the clamping part 210 extends from the middle of one side wall 224 of the receiving part 220. The wire extending direction of the clamping part 210 is perpendicular to the insertion direction of the receiving part 220. Among them, the left wall 221 and the right wall 223 correspond to the thickness direction of the conductive sheet, that is, they are parallel to the thickness direction. The front wall 222 and the rear wall 224 correspond to the width direction of the conductive sheet, that is, they are parallel to the width direction. Here, the front and rear, left and right are relative. The front and rear refer to the two directions in the thickness direction of the conductive sheet, and the left and right refer to the two directions in the width direction of the conductive sheet.

[0042] The receiving part 220 can be inserted and connected to the conductive sheet 100 in a fixed position along the insertion direction. The insertion connection between the receiving part 220 and the conductive sheet 100 can clamp the periphery of the conductive sheet 100. In addition, since the wire extending direction of the clamping part is perpendicular to the insertion direction of the receiving part, that is, the conductive terminal is in a flag-shaped structure, it is beneficial to be applied to the situation where the space around the conductive terminal is limited.

[0043] In some examples, the four side walls of the receiving part may include protruding parts protruding into the receiving part. As Figures 2a - 2e shown, the four side walls include protruding parts 221a, 222a, 223a, 224a protruding into the box body. The protruding parts on each side wall can be located at the middle position of the side wall. The protruding parts 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 in a small size situation (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 the connection.

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

[0045] In some examples, the protruding parts on the side walls may include elastic pieces, and the elastic pieces can be formed by stamping. Refer to Figures 2a - 2c , between the side wall 221 and the side wall 222, between the side wall 222 and the side wall 223, between the side wall 223 and the side wall 224, stamping and cutting can be carried out, and four elastic pieces are formed by stamping along the thickness direction of the metal sheet at the middle position of the four side walls. The structure of the elastic pieces can squeeze the surface of the conductive sheet to form a holding force.

[0046] The elastic pieces can not only apply pressure to the conductive sheet, but also play a guiding role. For example, it can be referred to Figure 2b, the raised portions 221a and 223a are elastic sheet structures. During the process of inserting the receiving portion 220 into the conductive sheet 100, the raised 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 raised portions on the front wall and / or the rear wall may include bump structures. The bump structures can cooperate with the through holes 101 of the conductive sheet 100. When the receiving portion 220 is connected to the conductive sheet 100, the bump structures can be snap-connected to the through holes 101.

[0048] In some examples, the raised portion of one side wall in the front wall and / or the rear wall includes a bump structure, and the raised portion of the other side wall is an elastic sheet. For example, referring to Figures 2b - 2e , the raised portion 224a includes an elastic sheet and a bump structure 224b located on the elastic sheet, and the raised portions 221a, 222a, and 223a are elastic sheets. Figure 2d and Figure 2e shows a longitudinal sectional view of the receiving portion 220 from the front and rear perspectives. The bump structure 224b is located on the rear wall 224 at a position corresponding to the through hole 101. During the process of inserting the receiving portion 220 into the conductive sheet 100, the raised portions 221a, 222a, 223a, and 224a are all compressed and deformed. When reaching the through hole 101, the bump structure 224b is snap-connected to the through hole 101. In this way, when the conductive terminal 200 is connected to the conductive sheet 100, the raised portions on the four side walls not only press on the periphery of the conductive sheet 100 around the insertion direction, but also the bump structure 224b snap-connected to the through hole 101 can resist external vibrations 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 Figures 2a - 2e example, 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 raised portion 222a of the front wall 222 also includes a bump structure. Additionally, in some examples, the raised portions 222a and 224a can both include elastic sheets and bump structures located on the elastic sheets, thereby further improving the connection stability.

[0050] In some examples, the conductive terminal 200 can be integrally formed, that is, the clamping portion 210 and the receiving portion 220 are integrally formed. The conductive terminal 200 can be formed from an entire metal sheet by stamping, bending, etc. Now referring to Figure 2c, the conductive terminal 200 further includes a bending 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 body. The box body is joined at the left wall 221. In the middle of the left wall is a convex portion 221a, and at both ends are joining portions 221b. The joining portions 221b are dovetail structures arranged in an interleaved manner, which can improve the stability of the conductive terminal.

[0051] It can be understood that Figures 2c - 2d the shape of the convex dot structure 224b on is only an example, and it 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 other side walls of the receiving portion 220, not limited to Figures 2a - 2c the example of. In addition, the bending angle between the clamping portion 210 and the receiving portion 220 can be set flexibly to adapt to the space where the conductive sheet is located.

[0053] The size of the box body of the receiving portion can be matched with the size of the conductive sheet. For example, for a conductive sheet with a height of 3 mm and a width of 2 mm, the height of the box body can not exceed 3 mm, and the width of the internal space of the box body can not exceed 2 mm.

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

[0055] The conductive terminal 200 is a flag-shaped structure. In some other examples, the conductive terminal can adopt a linear structure. For example, the center lines of the wire core connection portion 212, the wire sheath connection portion 211, and the receiving portion 220 are on the same straight line.

[0056] Figure 3a The structural schematic diagram of the conductive terminal 300 of an embodiment of the present invention is shown. Figure 3b It is a top view of the conductive terminal 300. Figure 3c It is a schematic diagram showing the structure behind the conductive terminal 300. The difference between the conductive terminal 300 and the conductive terminal 200 lies in the different rear walls of the receiving portion. The differences between the two are elaborated below, and the same parts will not be described again.

[0057] According to Figures 3a - 3c , the raised portions of the left wall 321, the right wall 323, and the front wall 322 are all elastic pieces, while the raised portion of the rear wall 324 does not include an elastic piece but is only a bump structure 324b located on the rear wall. Figure 3d Fig. shows a longitudinal sectional view of the receiving portion 320 in the front view.

[0058] The bump structure 324b is located on the rear wall 324 at a position corresponding to the through hole 101. During the insertion of the receiving portion 320 into the conductive sheet 100, the raised portions 221a, 222a, and 223a are all deformed under pressure. When reaching the through hole 101, the bump structure 324b is engaged with the through hole 101. In this way, when the conductive terminal 300 is connected to the conductive sheet 100, the raised portions on the three side walls apply pressure to the conductive sheet 100, and the bump structure 324b engaged with the through hole 101 can resist external vibrations in the insertion direction.

[0059] It can be understood that although in the Figures 3a - 3d example, 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 raised portion of the front wall 322 is a bump structure, while the raised portion of the rear wall 324 is an elastic piece. In addition, in some examples, the raised portions 322a and 324a can both be bump structures, thereby further improving the connection stability.

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

[0061] Figure 4a Fig. shows a schematic structural view of a conductive terminal 400 according to an embodiment of the present invention. Figure 4b Fig. is a top view of the conductive terminal 400. Figure 4c Fig. is a schematic view showing the rear structure of the conductive terminal 400. The difference between the conductive terminal 400 and the conductive terminals 200 and 300 is that the conductive terminal does not include a bump structure. The differences from the conductive terminals 200 and 300 are mainly discussed below, and the same parts will not be described again.

[0062] According to Figures 4a - 4c , the raised portions of the left wall 421, the right wall 423, the front wall 422, and the rear wall 424 are all elastic pieces. Figure 4d Fig. shows a longitudinal sectional view of the receiving portion 420 in the front view.

[0063] When the conductive terminal 400 is used in cooperation with the conductive sheet 100, during the process of inserting the receiving portion 420 into the conductive sheet 100, the elastic pieces 421a, 422a, 423a, and 424a are all deformed under pressure. When the conductive terminal 400 is connected to the conductive sheet 100, the protruding portions on the four side walls exert pressure on 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 The structural schematic diagram of the conductive sheet 500 used in cooperation with an embodiment of the present invention is shown. Both sides of the conductive sheet 500 have recesses 511. The recesses 511 can be snap - connected to the conductive terminal 400.

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

[0066] An embodiment of the present invention also discloses an electrical connector, including a conductive terminal and a conductive sheet used in cooperation therewith. The conductive terminal can be any of the above - mentioned conductive terminals. 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 - connected to the conductive terminal.

[0067] The above - mentioned are only optional embodiments of the embodiments of the present invention and are not used to limit the embodiments of the present invention. For those skilled in the art, the embodiments of the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the embodiments of the present invention shall be included in the protection scope of the embodiments of the present invention.

[0068] Although the embodiments of the present invention have been described with reference to several specific embodiments, it should be understood that the embodiments of the present invention are not limited to the specific embodiments disclosed. The embodiments of the present invention are intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
