Abstract
Description
Technical Field
[0001] This invention relates to the field of connector technology, and in particular to a miniature combined floating connector. Background Technology
[0002] Floating connectors are used to connect two circuit boards. They typically include a male and a female connector (also called a male-terminal connector and a female-terminal connector) that interlock. The female connector has a floating mechanism, which eliminates misalignment of the circuit boards during assembly and reduces stress between the connector and the circuit board when it is inserted into the male connector. Existing floating board-to-board connectors often use L-shaped bent signal terminals in the female connector, allowing the floating mechanism a certain amount of floating to ensure that the male and female connectors can still interlock even when misaligned. However, when the misalignment is large, the length of the L-shaped bend needs to be increased, which increases the height of the female connector, making it unsuitable for some low-ceilinged workspaces. Furthermore, the L-shaped bend lacks longitudinal deformation, failing to meet the requirements of some vibration-prone applications. Therefore, this invention proposes a miniature combined floating connector. Summary of the Invention
[0003] The main objective of this invention is to provide a miniature combined floating connector, which solves the problem in the background art that existing floating connectors are too tall to fit into some low-ceilinged workspaces.
[0004] This invention achieves the above objective through the following technical solution: a miniature combined floating connector, comprising:
[0005] The base has a vertically penetrating movable cavity inside;

[0007] Multiple terminals are distributed on both sides of the insertion slot. Each terminal includes a soldering part, a contact part, and an elastic part connecting the soldering part and the contact part. The soldering part is fixed to the lower end face of the base for soldering to the circuit board. The contact part is embedded in the inner wall of the insertion slot. The elastic part is S-shaped and includes a first inclined section located between the base and the movable seat. The end of the first inclined section is connected to a second inclined section that is inclined outward. The end of the second inclined section is connected to a horizontal section. The contact part is vertically disposed on the upper end face of the horizontal section.
[0008] Preferably, the lower end face of the base is provided with a plurality of welding part limiting grooves, the welding part is located in the welding part limiting grooves, the upper end face of the welding part is provided with a first pin vertically, and the bottom of the base is provided with a first insertion hole vertically, the first pin being inserted into the first insertion hole.
[0009] Preferably, the insertion slot has multiple terminal limiting slots on both sides, and the lower end face of the movable seat has a terminal insertion hole that communicates with the terminal limiting slot. The contact part extends into the terminal limiting slot through the terminal insertion hole.
[0010] Preferably, the horizontal section supports the lower end face of the movable seat, the horizontal section is vertically provided with a second pin, the lower end face of the movable seat is provided with a second insertion hole, and the second pin is inserted into the second insertion hole.

[0013] Preferably, the outer periphery of the upper end face of the insertion slot is provided with a guide slope, and the inner periphery is provided with an arc-shaped transition surface that connects with the guide slope.
[0014] The beneficial effects of the technical solution of the present invention are: the connecting part is S-shaped, which allows the movable seat to move flexibly relative to each other in the X and Y directions, increasing the offset of the movable seat, thereby eliminating the misalignment phenomenon when the connector is mated;
[0015] The connecting part can also act as a "spring", serving multiple purposes such as vibration reduction, so that the floating connector can adapt to the vibration environment. Attached Figure Description
