Description

Technical Field

[0001] This invention relates to a connector structure, and more particularly to a plug structure having leaf spring type terminals. 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 sheet and a leaf spring type terminal. The conductive sheet is fixed inside the terminal block and extends with two opposing support arms. The leaf spring type terminal is installed on the support arms. When the male terminal is inserted into the terminal block, it is clamped by the leaf spring type terminal and electrically connected.

[0004] However, the above installation sequence is as follows: the leaf spring type terminal must first be fixed to the conductive sheet, and then the combined conductive sheet and leaf spring type terminal are installed inside the terminal block. Therefore, the leaf spring type terminal must be matched with the dimensions of the conductive sheet and the terminal block at the same time, which results in higher tolerance and assembly quality requirements for the leaf spring type terminal, thereby increasing manufacturing and assembly costs.

[0005] In view of this, the inventor has devoted himself to researching and applying theoretical principles to address the aforementioned problems in the prior art, which is the goal of the inventor's development. Summary of the Invention

[0006] This invention provides a plug structure with a leaf spring type terminal, which utilizes the leaf spring type terminal to be directly fixed on an insulating base. The size of the leaf spring type terminal only needs to match the insulating base, thereby saving the manufacturing and assembly costs of the leaf spring type terminal.

[0007] In an embodiment of the present invention, the present invention provides a plug structure with a leaf spring type terminal, comprising: an insulating base having a mounting surface, the mounting surface having a positioning groove and at least a pair of slots disposed on both sides of the positioning groove; a male terminal that passes through the positioning groove and protrudes from the mounting surface; and a leaf spring type terminal extending with at least a pair of tenons and a plurality of terminals, each tenon engaging with each slot, and the plurality of terminals being disposed corresponding to the male terminal.

[0008] Based on the above, the leaf spring type terminal is directly fixed to the insulating base by engaging with the slot of the insulating base through the latch. Compared with the conventional method, which requires first fixing the leaf spring type terminal to the conductive plate of the female base and then installing the combined conductive plate and leaf spring type terminal inside the insulating base, the present invention omits the assembly step of fixing the leaf spring type terminal to the conductive plate. This allows the size of the leaf spring type terminal to be manufactured only to match the insulating base, without the need to match the conductive plate. This reduces the tolerance and assembly requirements of the leaf spring type terminal, thereby saving the manufacturing and assembly costs of the leaf spring type terminal and making the installation of the leaf spring type terminal convenient and quick.

[0022] The detailed description and technical content of the present invention will be explained below in conjunction with the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the present invention.

[0023] Please refer to Figures 1 to 7 As shown, the present invention provides a plug structure with a leaf spring type terminal. The plug structure 10 is a male connector for a high current connector. The plug structure 10 mainly includes an insulating base 1, a male terminal 2 and a leaf spring type terminal 3.

[0024] like Figures 1 to 2 , Figures 4 to 7 As shown, the insulating base 1 in this embodiment is the base of the equipment end, but it is not limited thereto. The insulating base 1 has a mounting surface 11. The mounting surface 11 is provided with a positioning groove 111 and one or more pairs of locking grooves 12 disposed on both sides of the positioning groove 111. Each locking groove 12 has a conical guide area 121 and a conical locking area 122. The width W1 of each conical guide area 121 gradually decreases towards the conical locking area 122, and the width W2 of each conical locking area 122 gradually increases towards the conical guide area 121.

[0025] The following is a detailed description: In this embodiment, the insulating base 1 is provided with a slot 13, and the mounting surface 11 is formed on the inner bottom wall of the slot 13. However, the slot 13 is not a necessary structure and can be omitted depending on the actual situation. The number of slots 12 is three pairs, but this is not a limitation. The three pairs of slots 12 are respectively arranged side by side on opposite sides of the positioning slot 111.

[0026] like Figures 1 to 2 , Figures 4 to 7 As shown, the male terminal 2 is plate-shaped and made of conductive metal such as copper. The male terminal 2 is fixed in the positioning groove 111 and protrudes from the mounting surface 11. That is, the head of the male terminal 2 in this embodiment is accommodated in the slot 13.

[0027] like Figures 1 to 7 As shown, the leaf spring type terminal 3 has a frame 31 sleeved on the male terminal 2 and extends one or more pairs of tenons 32 and a plurality of terminals 33. Each tenon 32 has a conical locking block 321 at its end. Each conical locking block 321 can be inserted from each conical guide area 121 and locked in each conical locking area 122. The shape of each conical locking area 122 matches that of each conical locking block 321 so that each tenon 32 is engaged in each locking groove 12. When the conical locking block 321 moves towards the conical guide area 121, it will have an interference fit with the conical locking area 122, thereby preventing the conical locking block 321 from disengaging from the conical locking area 122.

[0028] Further explanation is as follows: In this embodiment, the number of tenons 32 is three pairs, but this is not a limitation. Each tenon 32 has an L-shaped bent section 322 extending from the end of the frame 31. The L-shaped bent sections 322 of each pair of tenons 32 extend side by side from the end of the frame 31. Each conical block 321 is formed at the end of each L-shaped bent section 322. A portion of each L-shaped bent section 322 passes through each conical guide area 121. A plurality of terminals 33 are provided corresponding to the male terminal 2.

[0029] In addition, the frame 31 in this embodiment is a U-shaped plate 311 arranged along the front, rear and top sides of the male terminal 2, but it is not limited thereto. The U-shaped plate 311 is provided with a double number of hollow openings 312 corresponding to the front and rear sides. The plurality of terminals 33 extend from one side of the inner periphery of each hollow opening 312 into each hollow opening 312.

[0030] Furthermore, the plurality of terminals 33 are arranged longitudinally side by side, and each terminal 33 is bent to have one or more first V-shaped bends 331 that abut against the front and rear sides of the male terminal 2 and one or more second V-shaped bends 332 that are bent in the opposite direction to the first V-shaped bends 331.

[0031] like Figures 2 to 7 As shown, in the usage state of the plug structure 10 of the present invention, the spring-type terminal 3 is engaged with the slot 12 of the insulating base 1 through the tenon 32, so that the spring-type terminal 3 is directly fixed on the insulating base 1. Compared with the conventional method, which requires fixing the spring-type terminal to the conductive sheet of the female base first, and then installing the combined conductive sheet and the spring-type terminal inside the insulating base, the present invention omits the assembly step of fixing the spring-type terminal to the conductive sheet. This allows the size of the spring-type terminal 3 to only need to match the insulating base 1, without needing to match the conductive sheet, thereby reducing the tolerance and assembly requirements of the spring-type terminal 3, thus saving the manufacturing and assembly costs of the spring-type terminal 3, and making the installation of the spring-type terminal 3 convenient and quick.

[0032] In addition, the tapered guide area 121 gradually narrows its width W1 towards the tapered locking area 122 to guide the tapered locking block 321 to be smoothly inserted into the tapered locking area 122, thereby improving the assembly convenience of the plug structure 10.

[0033] Furthermore, the plug structure 10 in this embodiment is a male connector for a high-current connector, used to mate with the conductive piece 101 of the female connector 100. When the conductive piece 101 is inserted into the slot 13, it can press against the second V-shaped bend 332 of the plurality of terminals 33, so that the conductive piece 101 and the male terminal 2 are electrically connected to each other through the plurality of terminals 33, and has excellent conductivity due to the multiple contacts of the plurality of terminals 33.

[0034] Furthermore, conventional inventions only install leaf spring type terminals on the conductive sheet of the female connector. In contrast, the present invention installs leaf spring type terminals 3 on the insulating base 1 of the plug structure 10 to ensure that the male terminal 2 is continuously attached to the leaf spring type terminals 3, and can be more flexibly applied to various different occasions.

[0035] like Figures 8 to 10 As shown, this is another embodiment of the plug structure 10 of the present invention. Figures 8 to 10 Implementation examples and Figures 1 to 7 The embodiments are largely the same. Figures 8 to 10 Implementation examples and Figures 1 to 7 The difference between the embodiments lies in the different structure of frame 31.

[0036] In this embodiment, the frame 31 is a U-shaped plate 313 arranged along the front, rear, left, and right sides of the male terminal 2. The U-shaped plate 313 has twice the number of cutouts 312' corresponding to the front and rear sides. A plurality of terminals 33 extend from one side of the inner periphery of each cutout 312' into each cutout 312'. This achieves the same effect as... Figures 1 to 7 The functions and effects of the embodiments.

[0037] like Figures 11 to 13 The diagram shows another embodiment of the plug structure 10 of the present invention. Figures 11 to 13 Implementation examples and Figures 1 to 7 The embodiments are largely the same. Figures 11 to 13 Implementation examples and Figures 1 to 7 The difference between the embodiments lies in the different structure of frame 31.

[0038] In this embodiment, the top surface of the male terminal 2 is recessed with one or more grooves 21 penetrating the front and rear sides. The frame 31 has two strip-shaped uprights 314 corresponding to the front and rear sides of the male terminal 2, and three or more L-shaped bending ribs 315 extending from one strip-shaped upright 314 to the other strip-shaped upright 314 and embedded in the grooves 21 and the left and right sides corresponding to the male terminal 2. Each strip-shaped upright 314 has a hollow opening 312” between each pair of adjacent L-shaped bending ribs 315. The plurality of terminals 33 extend upward from the bottom side of the inner periphery of each hollow opening 312”. The extending directions of the three or more L-shaped bending ribs 315 are staggered. In this way, the same as Figures 1 to 7 The functions and effects of the embodiments.

[0039] In summary, the plug structure with leaf spring type terminals of the present invention has not been seen in similar products or publicly used before, and has industrial applicability, novelty and inventiveness, and fully meets the requirements for patent application. Therefore, this application is filed in accordance with the Patent Law to protect the inventor's rights.
