Description

Technical Field

[0001] This invention relates to a connector structure, and more particularly to a socket structure having leaf spring type terminals. Background Technology

[0002] High-current connectors are typically 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 leaf spring type terminal. The conductive plate 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 socket structure with leaf spring type terminals, which are directly fixed to an insulating base. The size of the leaf spring type terminals only needs to match the insulating base and does not need to be matched with conductive sheets, thereby saving the manufacturing and assembly costs of the socket structure.

[0007] In an embodiment of the present invention, the present invention provides a socket structure with a leaf spring type terminal, comprising: an insulating base having a slot and at least a pair of slots disposed on both sides of the slot; a conductive sheet being accommodated inside the insulating base, the conductive sheet having two arms passing through the slot, the two arms having two opposing inner sidewalls; and at least one leaf spring type terminal having at least a pair of tenons extending from one side and a plurality of terminals extending from the other side, each tenon engaging with each slot, the plurality of terminals being disposed corresponding to the two inner sidewalls.

[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 a tenon. Compared with the known method that requires fixing the leaf spring type terminal to the conductive sheet first and then installing the combined conductive sheet 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 sheet. This allows the size of the leaf spring type terminal to be manufactured only to match the insulating base, without needing to match the conductive sheet. This reduces the tolerance and assembly requirements of the leaf spring type terminal, thereby saving on the manufacturing and assembly costs of the socket structure. Attached Figure Description

[0039] 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.

[0040] Please refer to Figures 1 to 7 As shown, the present invention provides a socket structure with leaf spring type terminals. The socket structure 10 is a female socket of a high current connector. The socket structure 10 mainly includes an insulating base 1, a conductive sheet 2 and one or more leaf spring type terminals 3.

[0041] like Figures 1 to 2 , Figures 4 to 7 As shown, the insulating base 1 in this embodiment is a terminal block body, but it is not limited thereto. The insulating base 1 is provided with a slot 11 and one or more pairs of slots 12 arranged on both sides of the slot 11. Each slot 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.

[0042] The insulating base 1 has a front sidewall 13, and a slot 11 is opened from the front sidewall 13. The insulating base 1 has two inner wall surfaces 14 formed inside the slot 11 on the left and right sides. The front sidewall 13 and the two inner wall surfaces 14 are recessed together with two recessed grooves 15. The two recessed grooves 15 are arranged on both sides of the slot 11 and communicate with the slot 11. One or more pairs of slots 12 are opened from the bottom wall of the two recessed grooves 15.

[0043] like Figure 2 , Figures 5 to 7As shown, the conductive sheet 2 is U-shaped and made of conductive metal such as copper. The conductive sheet 2 is housed inside the insulating base 1. The conductive sheet 2 has two arms 21 that pass through the slot 11. The two arms 21 have two opposing inner sidewalls 22.

[0044] like Figures 1 to 7 As shown, the number of leaf spring type terminals 3 in this embodiment is two, but this is not a limitation. One or more pairs of latches 32 extend from one side of each leaf spring type terminal 3 and multiple terminals 33 extend from the other side. One latch 32 of each pair extends from one leaf spring type terminal 3, and the other latch 32 of each pair extends from the other leaf spring type terminal 3. Each latch 32 has a conical latch 321 at its end. Each conical latch 321 can be inserted into and latched in each conical latching area 122 from each conical guide area 121. The shape of each conical latching area 122 matches that of each conical latch 321 so that each latch 32 is engaged in each latching groove 12. When the conical latch 321 moves toward the conical guide area 121, it will have an interference fit with the conical latching area 122, thereby preventing the conical latch 321 from disengaging from the conical latching area 122.

[0045] Furthermore, multiple terminals 33 are arranged in parallel with each other on two inner sidewalls 22, and each terminal 33 is bent with one or more first V-shaped bends 331 that abut against the inner sidewall 22 of the conductive sheet 2 and one or more second V-shaped bends 332 that are bent in the opposite direction to the first V-shaped bends 331.

[0046] Further explanation is as follows: In this embodiment, each leaf spring type terminal 3 has an upright piece 31, each latch 32 has a U-shaped bend 322, the U-shaped bend 322 and the plurality of terminals 33 extend from the opposite sides of the upright piece 31, and each conical latch 321 is formed at the end of each U-shaped bend 322.

[0047] In addition, in this embodiment, each leaf spring type terminal 3 extends two tenons 32, but this is not a limitation, so that the U-shaped bends 322 of the two tenons 32 extend from the opposite sides of the upright piece 31 with the multiple terminals 33. One or more U-shaped bends 322 of each leaf spring type terminal 3 are partially inserted into each conical guide area 121 and the remaining part is accommodated in each recessed groove 15.

[0048] Furthermore, in this embodiment, there are two pairs of slots 12 and tenons 32. Two slots 12 are opened from the bottom wall of one recessed groove 15, and the other two slots 12 are opened from the bottom wall of the other recessed groove 15. Two tenons 32 extend from one upright piece 31, and the other two tenons 32 extend from the other upright piece 31.

[0049] like Figures 2 to 7As shown, in the usage state of the socket structure 10 of the present invention, the spring-type terminal 3 is engaged with the slot 12 of the insulating base 1 by the tenon 32, so that the spring-type terminal 3 is directly fixed on the insulating base 1. Compared with the known method that the spring-type terminal needs to be fixed to the conductive sheet first, and then the combined conductive sheet and the spring-type terminal are installed 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 be made only to match the insulating base 1, without needing to match the conductive sheet 2. This reduces the tolerance and assembly requirements of the spring-type terminal 3, thereby saving the manufacturing and assembly costs of the socket structure 10 and making the installation of the socket structure 10 convenient and quick.

[0050] 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. A portion of the U-shaped bending section 322 passes through each tapered guide area 121 and the remaining portion is accommodated in each recessed groove 15 to prevent the U-shaped bending section 322 from protruding from the insulating base 1, thus improving the assembly convenience of the socket structure 10.

[0051] Furthermore, the socket structure 10 in this embodiment is a female socket for a high-current connector, used to mate with a male terminal 100. When the male terminal 100 is inserted into the slot 11, it can press against the second V-shaped bend 332 of multiple terminals 33, so that the male terminal 100 and the two arms 21 of the conductive sheet 2 are electrically connected to each other through multiple terminals 33, and has excellent conductivity due to the multiple contacts of multiple terminals 33.

[0052] In summary, the socket structure with leaf spring type terminals of the present invention has never been seen in similar products or publicly used, and has practicality, novelty and inventiveness, fully meeting the requirements for patent application. Therefore, an application is filed in accordance with the Patent Law to protect the inventor's rights.
