[0002] In the electronics, automotive and other fields, push-button electrical connectors are used for quick circuit connection.
[0003] Existing push-button electrical connectors mostly use a single metal spring, which has drawbacks such as easy fatigue due to elasticity, uneven force during button extension and retraction, and insufficient connection reliability, making it difficult to meet the requirements for efficient and stable electrical connections. Continuously designing various types of electrical connectors with balanced elasticity and reliable performance has always been a research direction for those skilled in the art. Utility Model Content
[0004] The problem to be solved by this utility model is to provide a push-button electrical connector terminal with staggered C-shaped springs.
[0005] To solve the above problems, this utility model provides a push-button electrical connector terminal with staggered C-shaped spring contacts. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows: A push-button type electrical connector terminal with staggered C-shaped springs includes: an injection-molded shell; a plug protruding from one axial end of the injection-molded shell; elastic sheets that are in contact with the inner wall of the injection-molded shell, the elastic sheets being C-shaped; and a button, wherein the injection-molded shell has a window opening penetrating its inner and outer walls, and the button is movably mounted in the window opening; wherein two elastic sheets are axially staggered, the C-shaped openings of the two elastic sheets are in opposite directions, the button is mounted to the middle of the elastic sheets, and the elastic sheets are used to provide a radial elastic restoring force to the button.
[0006] As a further improvement of this utility model, the thickness direction of the elastic sheet is radial to that of the injection-molded shell.
[0007] As a further improvement of this utility model, the two button components are distributed symmetrically on both sides of the injection molded shell.
[0008] As a further improvement of this utility model, one side of the middle portion of the elastic sheet has a laterally extending widened portion, and the other side of the middle portion of the elastic sheet has a laterally recessed notch portion.
[0009] As a further improvement of this utility model, the button has an outward protrusion and an extension piece. The outward protrusion is movably fitted into the window opening, and the extension piece extends axially and contacts the inner wall of the injection molded shell.
[0010] As a further improvement of this utility model, the end of the extension piece is provided with a radially inwardly extending hook, one side of which abuts against the top of the widened portion or the bottom of the notch portion.
[0011] As a further improvement of this utility model, the projected contour of the outer protrusion along the radial direction of the injection molded shell is a waist-shaped hole, and the length direction of the waist-shaped hole is perpendicular to the axial direction of the injection molded shell.
[0012] As a further improvement of this utility model, the plug is made of conductive metal and has a through hole extending laterally.
[0013] As a further improvement of this utility model, the inner wall of the injection molded shell has a stepped surface, which contacts the edge of the elastic sheet; the shaft end of the injection molded shell has an axially extending boss, the tops of all the bosses coincide on the same spatial plane, and the bosses and the plug are respectively located at the two shaft ends of the injection molded shell.
[0014] As a further improvement of this utility model, one end of the injection molded shell has a flange that extends radially outward integrally, and the flange and the plug are respectively located at the two axial ends of the injection molded shell.
[0015] The beneficial technical effects of using the push-button electrical connector terminal with staggered C-shaped spring contacts of this application are: Two axially intersecting elastic sheets with opposite C-shaped openings work together to provide radial elastic force. Compared with a single elastic sheet structure, the elastic force is more balanced, which can effectively reduce elastic fatigue and improve the stability and life of the terminal.
[0016] The button and the elastic sheet are directly assembled in the middle, and the elastic force of the elastic sheet is transmitted directly and in a concentrated manner, so that the extension and retraction of the button is smooth and without jamming, the force is evenly distributed, and the feel and reliability of the pressing operation are improved.
[0017] The compact design of the C-shaped elastic sheet in contact with the inner wall of the injection-molded shell minimizes the space occupied by the shell cavity, avoids interference with other components inside the shell, and ensures a smooth and stable electrical connection process.

Detailed Implementation
[0021] The present invention will be further described in detail below with reference to specific embodiments: To achieve the purpose of this utility model, please refer to Figures 1 to 7 A push-button electrical connector terminal with staggered C-shaped spring contacts includes: an injection-molded shell 2; a plug 1 protruding from one axial end of the injection-molded shell 2; at least one elastic piece 4, which is C-shaped and contacts the inner wall of the injection-molded shell 2; and a button 3, in which the injection-molded shell 2 has a window opening 201 extending through its inner and outer walls. Two elastic pieces 4 are axially staggered, with their C-shaped openings facing opposite directions, and the two elastic pieces 4 do not contact each other. Figure 3 As shown, a gap 5 is formed between the two elastic pieces 4. The button 3 is assembled with the middle of the elastic piece 4, and the elastic piece 4 provides the button 3 with radial extension and retraction force.
[0022] The beneficial effects of adopting the above technical solution are: the outer injection-molded shell 2 is used for insulation and to provide structural support, the plug 1 in the middle undertakes the conductive function, and the internal C-shaped elastic piece 4 provides elastic extension force for the side button 3 when pressed, realizing locking or unlocking when the terminal is plugged in or out, thereby ensuring the stability and convenience of the circuit connection. This is commonly seen in consumer electronics, automotive electronics and other scenarios that require quick plugging and unplugging.
[0023] Moreover, compared to other forms such as springs, the elastic sheet 4 can fit tightly against the inner wall of the injection molded shell 2, occupying very little space in the inner cavity of the injection molded shell 2, and will not interfere with other conductive components inside the injection molded shell 2.
[0024] The two button components are symmetrically distributed, which makes the resistance and limiting force when the terminals are inserted and removed symmetrical.
[0025] When the terminal is inserted into the external interface, the button 3 is forced to move radially inward, causing the button 3 to press the middle of the elastic sheet 4. Since the elastic sheet 4 itself has elasticity and has an elastic tendency to restore its original shape, the button 3 also always has radial outward elasticity.
[0026] In some other embodiments of this utility model, the thickness direction of the elastic sheet 4 is radial to that of the injection-molded shell 2.
[0027] The beneficial effects of adopting the above technical solution are: it optimizes the radial elastic deformation capability of the elastic sheet 4, improves the elastic force application efficiency, and reduces the risk of interference with other components in the injection molded shell 2, making the structure more compact.
[0028] like Figure 3 As shown, in some other embodiments of this utility model, two button components 3 are mirror-symmetrically distributed on both sides of the injection-molded shell 3. The two button components 3 are located at the same cross-sectional position of the injection-molded shell 3.
[0029] The beneficial effects of adopting the above technical solution are: this symmetrical layout makes the resistance and limiting force during terminal insertion and removal evenly distributed, improves the operational consistency of the connection process, and avoids wear or failure caused by uneven force on one side.
[0030] like Figure 4 As shown, in some other embodiments of the present invention, one side of the middle portion of the elastic sheet 4 has a laterally extending widened portion 402, and the other side of the middle portion of the elastic sheet 4 has a laterally recessed notch portion 403.
[0031] In addition, such as Figure 4 As shown, the elastic sheet 4 has narrowing portions 401 at both ends.
[0032] The beneficial effects of adopting the above technical solution are: this structure increases the local rigidity and elastic deformation space of the elastic sheet 4, making the elastic force distribution more reasonable, improving the response sensitivity of the button 3 and the service life of the elastic sheet 4.
[0033] like Figure 1 , Figure 4 , Figure 5As shown, in some other embodiments of this utility model, the button 3 has an outward protrusion 301 and an extension piece 302. The outward protrusion 301 is movably fitted into the window opening 201, and the extension piece 302 extends axially and contacts the inner wall of the injection molded shell 2.
[0034] The beneficial effects of adopting the above technical solution are: it enhances the guidance and stability of the button component 3, prevents the button from tilting or getting stuck during operation, and ensures smooth operation.
[0035] like Figure 4 , Figure 5 As shown, in some other embodiments of the present invention, one side of the middle portion of the elastic sheet 4 has a laterally extending widened portion 402, and the other side of the middle portion of the elastic sheet 4 has a laterally recessed notch portion 403. The end of the extension piece 302 has a radially inwardly extending hook 303, one side of which abuts against the top of the widened portion 402 or the bottom of the notch portion 403.
[0036] In addition, such as Figure 4 As shown, the center of the protrusion 303 has a groove 304 for easy centering.
[0037] The beneficial effects of adopting the above technical solution are: this connection method makes the force transmission between the button 3 and the elastic sheet 4 more direct and reliable, and improves the pressing efficiency.
[0038] In some other embodiments of this utility model, the projected outline of the outer protrusion 301 along the radial direction of the injection molded shell 2 is a waist-shaped hole, and the length direction of the waist-shaped hole is perpendicular to the axial direction of the injection molded shell 2.
[0039] The beneficial effects of adopting the above technical solution are: this shape allows the button part 3 to have a certain adjustment space when moving radially, which can adapt to different assembly tolerances and ensure that the button action is smooth and not easily jammed.
[0040] In some other embodiments of this utility model, the plug 1 is made of conductive metal and has a through hole 101 extending laterally.
[0041] The beneficial effects of adopting the above technical solution are: the weight of the terminal is reduced by the through hole 101, which makes it easier to connect or fix other components and enhances practicality.
[0042] like Figure 6 As shown, in some other embodiments of this utility model, the inner wall of the injection-molded shell 2 has a stepped surface 204, which contacts the edge of the elastic sheet 4. The shaft end of the injection-molded shell 2 has an axially extending boss 205, the top surfaces of all bosses 205 coincide in the same spatial plane, and the bosses 205 and the plug 1 are respectively located at the two shaft ends of the injection-molded shell 2.
[0043] The beneficial effects of adopting the above technical solution are: it ensures the accurate positioning and stable support of the elastic sheet 4, while the boss 205 provides the alignment reference for the terminals, which facilitates installation and docking and improves the overall structural reliability.
[0044] like Figure 7 As shown, in some other embodiments of the present invention, one end of the injection molded shell 2 has a flange 203 that extends radially outward integrally, and the flange 203 and the plug 1 are respectively located at the two axial ends of the injection molded shell 2.
[0045] The beneficial effects of adopting the above technical solution are: the flange 203 provides additional fixing points, which facilitates the installation and fixing of terminals in the housing and enhances the tensile strength of the overall structure.
