Abstract

The utility model relates to a pull-out assisting device of a laminated connector, which comprises a PCB daughter board and a PCB mother board. The lower surface of the PCB daughter board is fixedly connected with a daughter head, a butt joint slot and an elastic limit fixture block are arranged in the daughter head, the upper surface of the PCB mother board is provided with a connecting mother head, and the butt joint slot is clamped with the limit fixture block. Wherein the mechanical linkage unlocking is realized by arranging a toggle plate in the PCB motherboard and rotationally connecting the toggle plate with the PCB motherboard through a torsional spring type elastic rotating shaft. The poking plate pulls the butt-joint plug block through the pull rope, and the clamping connection is released during pulling, so that the pin damage caused by direct pulling and inserting is avoided. The novel pulling assisting device presses the butt-joint plug block during installation, the limiting fixture block deforms and is clamped, the bolts are fixed, the pulling plate is pulled during disassembly, the pull rope pulls the butt-joint plug block to be separated from the clamping connection, and the sub-boards can be separated stably. The device solves the problem that the pins are easy to damage when the laminated connector is disassembled through mechanical linkage and multiple protection design, and has high efficiency and safety.

Description

Pulling-assisting device of laminated connector Technical Field The utility model relates to the field of laminated connectors, in particular to a pull-out assisting device of a laminated connector. Background The laminated connector is an electronic connector, and can realize electrical connection among a plurality of circuit boards or modules in a limited space through a multi-layer stacking design, and is widely applied to modern electronic equipment due to a high-density and compact structure. However, when the existing laminated connector is connected, after the two butt joint plates are provided with the positioning buckles for locking, the bolts are used for locking, and when the bolts are detached when the bolts are needed to be detached, the two butt joint plates are directly pulled out under the action of the positioning buckles to easily cause the deflection of force, so that the pins are easily damaged. Disclosure of utility model In order to solve the technical problems, the utility model provides a pull-out assisting device of a laminated connector, which comprises a PCB sub-board and a PCB motherboard, wherein a connector sub-head is arranged on the lower surface of the PCB sub-board, a butt joint slot is arranged in the connector sub-head, and a limit clamping block is arranged in the butt joint slot; A connecting female head is arranged on the upper surface of the PCB motherboard, a butt joint block corresponding to the butt joint slot is arranged on the upper surface of the connecting female head, and the butt joint block and the limit clamping block form a releasable clamping structure; a poking plate is arranged in the PCB motherboard, and the poking plate is rotationally connected with the PCB motherboard through an elastic rotating shaft; The butt-joint insertion block is fixedly connected with the poking plate through a pull rope at one side far away from the limiting clamping block, and a limiting sleeve ring fixed on the side surface of the connecting female head is arranged at the outer side of the pull rope; When the poking plate is poked, the pull rope is pulled to drive the butt-joint plug block to separate from the limit fixture block, so that the separation of the PCB daughter board and the PCB mother board is realized.
