Description

Technical Field

[0001] This utility model relates to the field of stacked connectors, specifically a pull-out aid device for stacked connectors. Background Technology

[0002] A stacked connector is an electronic connector that enables electrical connections between multiple circuit boards or modules within a limited space through a multi-layer stacking design. Its high-density and compact structure makes it widely used in modern electronic devices. Stacked connectors achieve multiple connections within a limited space, support various stacking methods, adapt to different needs, and ensure the stability of electrical connections.

[0003] However, current multilayer connectors have positioning buckles for locking the two mating plates during connection, and then bolts for securing them. When disassembly is required, removing the bolts and pulling the two mating plates apart under the action of the positioning buckles can easily cause force displacement, thus damaging the pins. Utility Model Content

[0004] To solve the above technical problems, this utility model provides a pull-out aid device for a multilayer connector, including a PCB daughter board and a PCB mother board. A connector head is installed on the lower surface of the PCB daughter board, and a mating slot is provided inside the connector head. A limit block is configured in the mating slot.

[0005] The upper surface of the PCB motherboard is equipped with a connecting female head, and the upper surface of the connecting female head is provided with a docking block corresponding to the docking slot, and the docking block and the limiting block form a releasable locking structure.

[0006] The PCB motherboard is equipped with a toggle plate inside, and the toggle plate is rotatably connected to the PCB motherboard through an elastic rotating shaft;

[0007] The docking plug is fixedly connected to the actuating plate on the side away from the limiting block by a pull rope, and the pull rope is provided with a limiting collar fixed to the side surface of the connecting female head;

[0008] When the actuating plate is moved, the pull rope is pulled and causes the docking plug to disengage from the limiting block, thereby realizing the separation of the PCB daughter board and the PCB mother board.

[0009] As a further improvement of this utility model: the internal part of the connecting female head is provided with a bolt hole, and the internal part of the PCB daughter board is provided with a fastening bolt. The fastening bolt engages with the bolt hole thread to fix the PCB daughter board and the PCB mother board.

[0010] As a further improvement of this utility model: a foolproof socket is provided on one side of the connector male, and a foolproof rod is provided inside the connector female, the foolproof rod cooperating with the foolproof socket to prevent mis-insertion.

[0011] As a further improvement of this utility model: the elastic rotating shaft is a torsion spring structure, which normally resets the toggle plate to its initial position.

[0012] As a further improvement of this utility model: the bolt holes are symmetrically distributed on both sides of the mating block, and the number of fastening bolts matches the number of bolt holes.

[0013] As a further improvement of this utility model, the limiting collar is a rigid guide ring used to constrain the movement path of the pull rope.

[0014] As a further improvement of this utility model, the contact surface between the docking block and the docking slot is a beveled structure to guide the docking block to be smoothly inserted or withdrawn.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] ①Limit release is achieved through mechanical linkage (toggle plate - pull rope - docking block), making operation labor-saving and precise.

[0017] ② The foolproof design and bolt fixing provide dual protection, improving connection reliability.

[0018] ③ The automatic reset function of the flexible shaft simplifies repetitive operation procedures. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-4 As shown, this embodiment provides a pull-out aid for a stacked connector, including a PCB daughter board 1 and a PCB mother board 2;

[0027] PCB sub-board 1 and connector 3: A connector 3 is fixedly installed on the lower surface of the PCB sub-board 1. The connector 3 has a mating slot 301 inside, and a limiting block 302 is configured in the slot. The limiting block 302 is made of elastic material and can deform under external force to achieve locking or releasing.

[0028] PCB motherboard 2 and connecting female head 4: A connecting female head 4 is fixedly installed on the upper surface of the PCB motherboard 2. The upper surface of the connecting female head 4 is provided with a mating block 401 corresponding to the mating slot 301. The mating block 401 and the limiting block 302 form a releasable snap-fit ​​structure, and its contact surface is designed as an inclined surface. Figure 2 This guides the insertion or removal of the plug smoothly.

[0029] Actuating plate 6 and linkage mechanism: An actuating plate 6 is provided inside the PCB motherboard 2, and the actuating plate 6 is rotatably connected to the PCB motherboard 2 via an elastic rotating shaft 601. The elastic rotating shaft 601 is a torsion spring structure, which normally returns the actuating plate 6 to its initial position. The side of the docking block 401 away from the limiting block 302 is fixedly connected to the actuating plate 6 via a pull rope 402. A limiting collar 403 is fixed to the side surface of the connecting female head 4 on the outside of the pull rope 402. The limiting collar 403 is a rigid guide ring that constrains the movement path of the pull rope 402 and ensures the stability of the pulling force direction.

[0030] like Figure 2-3 As shown, in this embodiment, the connector 3 has a foolproof socket 7 on one side, and the connector 4 has a corresponding foolproof rod (not labeled) inside. The size and position of the foolproof rod and the foolproof socket 7 are strictly matched to ensure that the insertion direction is unique and to avoid misoperation;

[0031] The connecting female head 4 has symmetrically arranged bolt holes 404 on both sides of the mating block 401. The PCB daughter board 1 has corresponding fastening bolts 5 installed inside, which are connected to the bolt holes 404 through thread engagement to enhance the fixing stability of the PCB daughter board 1 and the PCB mother board 2.

[0032] Furthermore, the torsion spring structure of the elastic rotating shaft 601 automatically drives it to reset to its initial position after the actuating plate 6 is released, providing preload for the next operation.

[0033] The installation process in the working principle of this utility model is as follows: Align the PCB daughter board 1 with the PCB mother board 2, insert the anti-foolproof plug into the anti-foolproof socket 7, and press the PCB daughter board 1 to insert the mating plug 401 into the mating slot 301. After the limiting block 302 is deformed by compression, it clamps the mating plug 401, and then the fastening bolt 5 engages with the bolt hole 404 through threaded engagement to complete the fixation;

[0034] The disassembly process is as follows: First, remove the fastening bolt 5, then move the actuating plate 6. The actuating plate 6 rotates around the elastic pivot 601, pulling the mating plug 401 outward via the pull rope 402, forcing the limiting block 302 to release its locking force. At this time, the PCB daughter board 1 can be smoothly separated away from the PCB mother board 2, avoiding damage to the pins due to uneven force caused by direct plugging and unplugging.

[0035] Therefore, in this embodiment, the pull-out device of the stacked connector has a rotating toggle plate that pulls the pull rope. The pull rope pulls the mating plug outward, breaking the limit between the mating plug and the limiting block. Thus, the PCB daughter board is directly moved away from the PCB mother board, which can prevent damage to the pins inside the connector and connector caused by directly pulling out the PCB daughter board and the PCB mother board.
