Abstract
Description
Technical Field
[0001] This application relates to a female terminal structure installed in a terminal block or connector, and more particularly to a female terminal module and its leaf spring type terminal structure. Background Technology
[0002] High-current connectors are commonly installed inside terminal blocks and are used to connect the power bus of network power devices, base stations, servers, Internet devices, or industrial power distribution equipment to the circuit board.
[0003] Traditional high-current connectors mainly consist of a female terminal assembly installed inside the terminal block and a male terminal that mates with the female terminal assembly. The female terminal assembly includes a conductive plate and a multi-contact terminal. The conductive plate is fixed inside the terminal block and extends with two opposing arms. The multi-contact terminal is installed on the arms. When the male terminal is inserted into the terminal block, it is clamped by the multi-contact terminal and electrically connected.
[0004] However, male terminals of different brands or models on the market have different thicknesses. If the male terminal is too thin, a gap will be created between it and the multi-contact terminal, making it difficult to connect with the multi-contact terminal. If the male terminal is too thick, it will be blocked by the multi-contact terminal and will be difficult to insert into the terminal block, causing the high-current connector to malfunction.
[0005] In view of this, the applicant has devoted himself to studying the aforementioned prior art and applying theoretical principles to try his best to solve the above-mentioned problems, which has become the target of the applicant's improvement. Summary of the Invention
[0006] This application provides a female terminal module and its leaf spring type terminal structure. The leaf spring type terminal structure allows for adjustment of the distance between the movable frame and the inner sidewall through a compressed elastic arm, thereby achieving the advantage that the female terminal module and leaf spring type terminal structure of this application are widely applicable to male terminals of different brands or models.
[0007] In this application embodiment, a female terminal module is provided, including: a conductive sheet having two support arms, the two support arms having two opposing inner sidewalls; and two leaf spring type terminal structures respectively installed on each support arm, each leaf spring type terminal structure including: a movable frame movably connected to the support arm and capable of approaching or moving away from the inner sidewall; a plurality of terminals extending from the movable frame in a direction away from the inner sidewall; and at least one elastic arm extending from the movable frame in a direction approaching the inner sidewall and abutting against the inner sidewall.
[0008] In the embodiments of this application, this application provides a leaf spring type terminal structure, which is installed on a conductive sheet. The conductive sheet has an inner sidewall. The leaf spring type terminal structure includes: a movable frame, which is movably connected to the conductive sheet and can approach or move away from the inner sidewall; a plurality of terminals, which extend from the movable frame in a direction away from the inner sidewall; and at least one elastic arm, which extends from the movable frame in a direction approaching the inner sidewall and abuts against the inner sidewall.
[0009] In one embodiment, one of the arms and one of the movable frames is provided with at least one groove, and the other of the arms and one of the movable frames extends with at least one slider that is slidably engaged with at least one groove, thereby allowing the movable frames to approach or move away from each inner sidewall.
[0010] In one embodiment, there are eight grooves and eight sliders, with four sliders protruding from the top and bottom of each arm. Each movable frame has two U-shaped frames corresponding to each inner sidewall, and two grooves are opened from both ends of each U-shaped frame.
[0011] In one embodiment, each terminal is an arc-shaped protrusion that extends integrally at both ends and spans between each of the two U-shaped frames.
[0012] In one embodiment, there are multiple elastic arms, each elastic arm having one end extending from its U-shaped frame and the other end forming a spaced V-shaped protrusion with another U-shaped frame.
[0013] In one embodiment, multiple arcuate protrusions and multiple V-shaped protrusions of each leaf spring type terminal structure are arranged alternately.
[0014] In one embodiment, the conductive sheet has an inner sidewall, and the leaf spring type terminal structure includes:
[0015] A movable frame is movably connected to the conductive sheet, allowing it to approach or move away from the inner wall;
[0016] Multiple terminals, extending from the movable frame away from the inner wall; and
[0017] At least one elastic arm extends from the movable frame toward the inner wall and abuts against the inner wall.
[0018] In one embodiment, one of the conductive sheet and the movable frame is provided with at least one groove, and the other of the conductive sheet and the movable frame extends with at least one slider that is slidably engaged with at least one groove, thereby allowing the movable frame to approach or move away from the inner sidewall.
[0019] In one embodiment, there are four grooves and four sliders, with the four sliders protruding from the top and bottom of the conductive sheet. The movable frame has two U-shaped frames arranged on the corresponding inner sidewalls, with two grooves opening from both ends of each U-shaped frame.
[0020] In one embodiment, each terminal is an arc-shaped protrusion that extends integrally at both ends and spans between two U-shaped frames.
[0021] In one embodiment, there are multiple elastic arms, each elastic arm having one end extending from one of its U-shaped frames and the other end forming a spaced V-shaped protrusion with another U-shaped frame.
[0022] In one embodiment, multiple arc-shaped protrusions and multiple V-shaped protrusions are arranged alternately.
[0023] Based on the above, the leaf spring type terminal structure can adjust the distance between the movable frame and the inner wall through the compression of the elastic arm, thereby allowing the elastic arm and the movable frame to share the pressure borne by the terminal. This ensures that when the female terminal module of this application is used with male terminals of different thicknesses, it can avoid the terminal from being excessively deformed by pressure and the male terminal from being excessively clamped. This achieves the advantage that the female terminal module and leaf spring type terminal structure of this application are widely applicable to male terminals of different brands or models.

[0050] The detailed description and technical content of this application will be explained below with reference to the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this application.
[0051] Please refer to Figures 1 to 8 As shown, this application provides a female terminal module and its leaf spring type terminal structure for use in terminal block 100 and male terminal 200. The female terminal module 10 mainly includes a conductive sheet 1 and two leaf spring type terminal structures 2. The leaf spring type terminal structure 2 mainly includes a movable frame 21, multiple terminals 22 and / or multiple elastic arms 23.
[0052] like Figures 1 to 8 As shown, the conductive sheet 1 is installed inside the terminal block 100. The conductive sheet 1 is U-shaped, but not limited to this shape. The conductive sheet 1 has two arms 11, and the inner sides of the two arms 11 have two opposing inner sidewalls 12.
[0053] like Figures 1 to 8As shown, each leaf spring type terminal structure 2 is installed on each support arm 11. When the male terminal 200 is inserted into the terminal block 100, the male terminal 200 will be inserted between the two leaf spring type terminal structures 2 and electrically connected to the conductive sheet 1 through the two leaf spring type terminal structures 2. Each leaf spring type terminal structure 2 includes a movable frame 21, multiple terminals 22 and one or more elastic arms 23.
[0054] The details are as follows: one of the support arms 11 and the movable frame 21 is provided with one or more grooves 3, and the other of the support arms 11 and the movable frame 21 extends with one or more sliders 4 that can be slidably engaged with one or more grooves 3, so that the movable frame 21 is movably connected to the support arms 11 and can approach or move away from the inner sidewall 12, that is, the movable frame 21 can approach or move away from the inner sidewall 12.
[0055] In this embodiment, the number of grooves 3 and sliders 4 are eight, but this is not a limitation. Each set of four sliders 4 protrudes from the top and bottom of each support arm 11. Each movable frame 21 has two U-shaped frames 211 corresponding to each inner sidewall 12. Each set of two grooves 3 is opened from both ends of each U-shaped frame 211, so that the U-shaped frame 211 can be fitted onto the outside of the sliders 4 of the support arm 11 through the grooves 3 and can slide relative to the sliders 4, so that the movable frame 21 can approach or move away from each inner sidewall 12.
[0056] Furthermore, the inner side of each slider 4 has an inclined surface 41 that gradually increases in thickness toward the support arm 11. The inclined surface 41 is used to guide the U-shaped frame 211 to be installed from the inner side of the slider 4, so that the two ends of the U-shaped frame 211 can slide along the inclined surface 41 until the slider 4 passes through the groove 3.
[0057] In addition, multiple terminals 22 extend from each movable frame 21 in a direction away from the inner sidewall 12. In this embodiment, each terminal 22 is an arc-shaped protrusion 221 that extends integrally at both ends across each of the two U-shaped frames 211 and is used to abut against the male terminal 200. However, this is not a limitation. Each terminal 22 can also be a protrusion of any geometric shape, such as a V-shape or W-shape, that extends integrally at both ends across each of the two U-shaped frames 211 and is used to abut against the male terminal 200.
[0058] Furthermore, the elastic arm 23 extends from each movable frame 21 toward the inner sidewall 12 and abuts against the inner sidewall 12. In this embodiment, there are multiple elastic arms 23. Each elastic arm 23 has one end extending from one of its U-shaped frames 211 and the other end forming a V-shaped protrusion 231 with a spacing S between it and another U-shaped frame 211. However, this is not a limitation. Each elastic arm 23 can also be a protrusion with any geometric shape, such as a U-shaped or W-shaped protrusion, with one end extending from one of its U-shaped frames 211 and the other end forming a spacing S between it and another U-shaped frame 211.
[0059] Furthermore, in this embodiment, the multiple arc-shaped protrusions 221 and multiple V-shaped protrusions 231 of each leaf spring type terminal structure 2 are arranged in an alternating manner, that is, the multiple terminals 22 and multiple elastic arms 23 are arranged in an alternating manner. Since the leaf spring type terminal structure 2 is made by first stamping and cutting the conductive metal sheet and then bending it, the multiple terminals 22 and multiple elastic arms 23 are arranged in an alternating manner, which can avoid stamping extra cutting grooves on the conductive metal sheet and save the waste of a lot of copper plate scraps generated in the process.
[0060] like Figures 4 to 6 As shown, in the usage state of the thinner male terminal 200 inserted into the female terminal module 10, because each movable frame 21 can approach or move away from each inner sidewall 12, the male terminal 200 will compress each elastic arm 23 when inserted between the two leaf spring type terminal structures 2, so that the leaf spring type terminal structure 2 can adjust the distance between the movable frame 21 and the inner sidewall 12 through the compressed elastic arms 23; as Figures 7 to 8 As shown, the thicker male terminal 200 of this application is inserted into the female terminal module 10 of this application. Because the male terminal 200 is thicker, when the male terminal 200 is inserted between the two leaf spring type terminal structures 2, it will compress each elastic arm 23 more, so that the movable frame 21 moves closer to the inner side wall 12.
[0061] In this way, the leaf spring type terminal structure 2 can adjust the distance between the movable frame 21 and the inner sidewall 12 through the compressed elastic arm 23, thereby allowing the elastic arm 23 and the movable frame 21 to share the pressure borne by the terminal 22. This ensures that when the female terminal module 10 of this application is used with male terminals 200 of different thicknesses, the terminal 22 can be prevented from being excessively deformed by pressure and the male terminal 200 can be excessively clamped. This achieves the advantage that the female terminal module 10 and the leaf spring type terminal structure 2 of this application are widely applicable to male terminals 200 of different brands or models.
