Description

Technical Field

[0001] The utility model relates to the technical field of terminal components, in particular to an integrated spring sheet and a connecting terminal. Background Art

[0002] The connection terminal is arranged in the high-voltage connector. The key to making the high voltage and high current pass smoothly in the high-voltage connector lies in the size of the contact area between the rib structure on the connection terminal and the power terminal. For example, a high-current contact rib disclosed in CN 218005297 U, a conventional connection terminal is provided with a spring on the inner wall of its connection port, and the spring has a curved rib structure to achieve effective plugging with the male terminal.

[0003] However, the monolithic reed structure is in a suspended state as a whole, which is easily deformed by external forces and has great instability. The monolithic structure makes the two relatively matched reeds independent and unable to affect each other. Especially after multiple plugging and unplugging, they will be deformed by the plugging and unplugging force, which will cause the distance between the two reeds to deviate, affecting the connection. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide an integrated spring sheet and a connecting terminal.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] The one-piece spring comprises an integrally formed first sheet, a connecting sheet and a second sheet, the first sheet and the second sheet having the same structure and being symmetrically connected to both sides of the connecting sheet, the connecting sheet being bent along its center line and protruding outward, the first sheet and the second sheet being relatively parallel and symmetrically arranged, a group of ribs extending in the same direction as the extension direction of the first sheet and the second sheet being evenly spaced on each other, each of the ribs being bent in a wave shape, and a contact point being formed at each bending point.

[0007] Preferably, the front and rear sides of the first and second sheets are respectively provided with a first connecting piece and a second connecting piece in sheet form, a group of the ribs are located between the first connecting piece and the second connecting piece, and both ends of each rib are respectively fixedly connected to the first connecting piece and the second connecting piece.

[0008] Preferably, limited gaps are formed on both sides of the outer edge of the first connecting piece, and the middle part of the outer edge of the first connecting piece has a flange folded outwards.

[0009] Preferably, the second connecting piece is connected to the connecting piece, and the two have the same length; the length of the second connecting piece is shorter than that of the first connecting piece, so that the first sheet body and the second sheet body form limited recesses on both sides close to the second connecting piece.

[0010] A connecting terminal comprises a terminal body and the integrated spring sheet as described above, wherein the front end of the terminal body forms a hollow plug-in port, the plug-in port is covered with a shell, the integrated spring sheet is clamped in the plug-in port, the first sheet body and the second sheet body abut against the inner wall of the terminal body, and the extension direction of the rib is consistent with the insertion direction of the plug-in port.

[0011] Preferably, a notch matching the flange is provided on the port edge of the plug port, and the flange is snap-fitted with the notch.

[0012] Preferably, a group of first limit blocks and second limit blocks are arranged on the inner wall of the terminal body, the first limit block is clamped in the notch, and the second limit block is clamped in the limit recess, and the first limit block and the second limit block jointly limit the position of the integrated spring sheet.

[0013] Preferably, a convex strip is provided on the inner wall of the terminal body which abuts against the first sheet body and the second sheet body.

[0015] Preferably, spring pieces that tilt outwards are symmetrically arranged on the outer side wall of the shell.

[0016] The beneficial effects of the utility model are mainly reflected in:

[0017] 1. The integrated structure makes the overall stability of the spring sheet higher. The connecting piece is connected to the first sheet body and the second sheet body respectively to effectively prevent the tail ends of the first sheet body and the second sheet body from being irreversibly deformed and lifted during the insertion process. At the same time, the connecting piece limits the insertion depth of the male terminal. The structure of the connecting piece convex along the center line is opposite to the force direction of the male terminal to effectively alleviate the impact during the insertion and removal process, avoid excessive deformation of the spring sheet, ensure long-term stability and reliability, and enhance the service life;

[0018] 2. The integrated structure makes the spring piece as a whole easier to manufacture and fix, making the first sheet and the second sheet more symmetrical, and the contact points between the upper and lower opposite ribs are directly opposite, ensuring effective connection with the male terminal when plugged in; the first limit block and the second limit block on the terminal body can effectively limit the entire spring piece;

[0019] 3. The second connecting piece is of the same length as the connecting piece, and is shorter than the first connecting piece. Such a structure makes the inner end width of the spring formed by the first sheet, the connecting piece, and the second sheet smaller than the outer end width, thereby enhancing the strength of the inner end and making it less susceptible to curling or excessive deformation at the inner end due to the influence of reverse plugging and unplugging force, thereby enhancing the overall stability of the spring.

[0026] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0027] In the description of the scheme, it should be noted that the terms "center", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0028] like Figure 1As shown, the utility model discloses an integrated spring sheet, comprising an integrally formed first sheet 101, a connecting sheet 102 and a second sheet 103, the first sheet 101 and the second sheet 103 having the same structure and being symmetrically connected to both sides of the connecting sheet 102, the connecting sheet 102 being bent along its midline and protruding outward, the first sheet 101 and the second sheet 103 being relatively parallel and symmetrically arranged, a group of ribs 105 extending in the same direction as the extending direction thereof being evenly spaced on the first sheet 101 and the second sheet 103, each of the ribs 105 being bent in a wave shape, and a contact 104 being formed at each bending position.

[0029] This solution adopts an integrated structure to make the overall stability of the spring sheet higher. The connecting piece 102 is connected to the first sheet 101 and the second sheet 103 respectively to effectively prevent the tail ends of the first sheet 101 and the second sheet 103 from irreversible deformation and warping during the insertion process. At the same time, the connecting piece 102 limits the insertion depth of the male terminal (not shown in the figure), and the structure of the connecting piece 102 convex along the center line is opposite to the force direction of the male terminal to effectively alleviate the impact during the insertion and removal process, avoid excessive deformation of the spring sheet, ensure long-term stability and reliability, and enhance the service life.

[0030] Specific as Figure 1 As shown, the front and rear sides of the first sheet 101 and the second sheet 103 are respectively provided with a sheet-shaped first connecting piece 106 and a second connecting piece 107, a group of ribs 105 are located between the first connecting piece 106 and the second connecting piece 107, and the two ends of each rib 105 are respectively fixedly connected to the first connecting piece 106 and the second connecting piece 107. In this solution, the preferred rib 105 is a closed structure with two ends respectively fixedly connected to the first connecting piece 106 and the second connecting piece 107 to limit the deformable length of the rib 105, thereby ensuring that the rib 105 maintains its elasticity and is easy to maintain its shape to ensure connection reliability. In other feasible embodiments, the rib 105 may also include a semi-open structure with one end fixed and the other end open.

[0031] Furthermore, limiting notches 110 are formed on both sides of the outer edge of the first connecting piece 106, and the middle part of the outer edge of the first connecting piece 106 has an outwardly folded flange 108, and the flange 108 is folded twice at 90° to form an inner contour with a C-shaped cross-section, so as to facilitate the connection with other components during installation.

[0032] The second connecting piece 107 is connected to the connecting piece 102, and the two are of the same length; the length of the second connecting piece 107 is shorter than that of the first connecting piece 106, so that the first sheet 101 and the second sheet 103 form limited recesses 109 on both sides close to the second connecting piece 107. Such a structure makes the inner end width of the spring formed by the first sheet 101, the connecting piece 102, and the second sheet 103 smaller than the outer end width, thereby enhancing the strength of the inner end, making it less likely to curl or over-deform at the inner end under the influence of the reverse plug-in force, thereby enhancing the overall stability of the spring.

[0033] Further, such as Figures 2 to 5 As shown, the present application also discloses a connection terminal, comprising a terminal body 2 and the above-mentioned integrated spring sheet, the front end of the terminal body 2 forms a hollow plug port 201, the plug port 201 is provided with a shell 3, the integrated spring sheet is clamped in the plug port 201, the first sheet 101 and the second sheet 103 abut against the inner wall of the terminal body 2, and the extension direction of the rib 105 is consistent with the insertion direction of the plug port 201. Such a structure enables the connection sheet 102 to limit the inner end in the plug port 201, that is, to limit the insertion depth of the male terminal.

[0034] Furthermore, a notch 202 matching the flange 108 is provided on the port edge of the plug port 201 , and the flange 108 is engaged with the notch 202 to define the setting position of the spring.

[0035] like Figure 5 As shown, a group of first limiting blocks 203 and second limiting blocks 204 are arranged on the inner wall of the terminal body 2, the first limiting blocks 203 are clamped in the notch 110, and the second limiting blocks 204 are clamped in the limiting recess 109, and the first limiting blocks 203 and the second limiting blocks 204 jointly define the position of the integrated spring. The first limiting blocks 203 and the second limiting blocks 204 are located at the four corners of the first sheet 101 and the second sheet 103 to define the positions of the first sheet 101 and the second sheet 103 from the front, back, left, and right sides, thereby defining the overall position of the spring to prevent it from moving.

[0036] Furthermore, a convex strip 205 is provided on the inner wall of the terminal body 2 that abuts against the first sheet 101 and the second sheet 103. The convex strip 205 is located between the first sheet 101, the second sheet 103 and the inner wall of the terminal body 2 to support the first sheet 101 and the second sheet 103 to prevent the first sheet 101 and the second sheet 103 from excessively deforming and fitting with the terminal body 2.

[0037] The housing 3 is sleeved outside the plug port 201 to limit the opening size of the plug port 201, so that the opening size of the plug port 201 remains stable and is not easily deformed and expanded by the plug-in and pull-out force.

[0038] Furthermore, a group of bayonet holes 206 are provided on the edge of the plug port 201, and a bayonet arm 301 matching the bayonet hole 206 is provided on the edge of the shell 3, and the bayonet arm 301 is engaged with the bayonet hole 206 to prevent the shell 3 from being disengaged. The convex strip 205 is preferably formed by stamping, so that a groove is formed on the back of the convex strip 205 to prevent the outer shell 3 from being overly fitted with the terminal body 2 and unable to be plugged in or out.

[0039] In addition, spring pieces 302 that are tilted outward are symmetrically arranged on the outer side wall of the housing 3 to facilitate the connection and positioning between the connecting terminal and the inner cavity of the connector when the connecting terminal is arranged in the connector.
