Board-to-board floating connecting terminal structure

Abstract

The invention discloses a board-to-board (BTB) floating connecting terminal structure, which comprises a base. The base is hollowed-out in the middle. A clamp seat is arranged in the middle hollowed-out part of the base. The clamp seat is internally provided with an annular groove and a connecting column, and the connecting column is located in the annular groove. Uniformly distributed connectingslots are arranged on the two sides of the connecting column. Metal connecting terminals are arranged in the connecting slots. The width of each connecting slot is greater than the width of each metalconnecting terminal, and the bottom of each connecting slot is fixedly connected with the corresponding metal connecting terminal. The front and rear ends of the clamp seat are fixedly connected withthe base. Connecting gaps are reserved between the left and right sides of the clamp seat and the base. The tails of the metal connecting terminals are fixedly connected with the inner side of the base, and the tails of the metal connecting terminals extend out of the bottom of the base through the connecting gaps after bending. Compared with the traditional BTB terminal, the metal connecting terminals of the board-to-board floating connecting terminal structure can float in the horizontal plane and in the vertical direction, and the floating structure design not only can guarantee a large number of insertions, but also can realize automatic calibration during connection with other structures and ensure the firmness of connection.

Description

technical field [0001] The invention relates to the field of board-to-board connectors, in particular to a board-to-board floating connection terminal structure. Background technique [0002] With the promotion and popularization of SMT (Surface Mount Technology, Surface Mount Technology) technology, the application of surface mount connectors is becoming more and more extensive, and various types of PCBs have corresponding surface mount connectors. From the through-hole (T / H) welding process to the surface mount (SMT) welding process, the terminal arrangement pitch (Pitch) of the connector can be reduced from 1.27mm  to 1.0mm, and gradually reduced to 0.8mm and 0.5mm , and the application of SMT technology allows soldering of electronic components on both sides of the PCB, greatly increasing the density of components on the PCB. Now all kinds of consumer electronic products using connectors have integrated miniaturization, thinning and high performance, which has prompted ...
