Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a floating board-to-board connector. Background Technology

[0002] Floating board-to-board 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 during circuit board 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 scenarios. Therefore, this invention proposes a floating board-to-board connector. Utility Model Content

[0003] The main objective of this invention is to provide a floating board-to-board connector. When the male and female connectors are misaligned, the inclined portion of the elastic segment provides a first deformation in the horizontal direction, and the contact portion of the elastic segment provides a second deformation in the horizontal direction. Compared to the L-shaped bend in the prior art, this greatly increases the deformation, allowing the male connector to accommodate larger misalignments without increasing the height of the female connector. The first horizontal portion, inclined portion, and second horizontal portion of the elastic segment form a Z-shaped bend, which acts as a "spring," absorbing some vibration in a vibrating environment and ensuring stable connector connection.

[0004] This utility model achieves the above objective through the following technical solution: a floating board-to-board connector, comprising a mating female connector and a male connector, characterized in that...

[0005] The female seat includes: a base, wherein the base is provided with a movable cavity;

The end of the first horizontal portion is connected to an outwardly inclined portion. The end of the inclined portion is connected to a second horizontal portion. The end of the second horizontal portion is connected to the contact section.

The elastic section 9 includes a first horizontal portion 10 located between the base 1 and the movable seat 4, parallel to the width direction of the base 1. The end of the first horizontal portion 10 is connected to an outwardly inclined portion 11. The end of the inclined portion 11 is connected to a second horizontal portion 12. The end of the second horizontal portion 12 is connected to the contact section.

[0031] The male seat includes: a housing 13, on which a insertion slot 14 is provided;

[0032] Multiple contact terminals are symmetrically distributed on both sides of the insertion slot 14. Multiple contact points 15 are provided on the contact surface of the contact terminal and the signal terminal 6. The multiple contact points 15 contact the contact segment 8 to prevent poor contact.

[0033] The bends of the elastic segment 9 are all designed with arc-shaped transitions.

[0034] The contact terminal includes a welding part 16, a connecting part 17, and a contact part 18. The welding part 16 is embedded in the housing 13, and one end of the welding part 16 extends out of the housing 13. The connecting part 17 is perpendicular to the welding part 16 and embedded in the housing 13. The contact part 18 is perpendicular to the welding part 16 and extends into the insertion groove 14. Terminal grooves are provided on both sides of the insertion groove 14. The contact part 18 is located in the terminal groove. Two contact points 15 are provided on the side of the contact part 18 that contacts the contact segment 8.

[0035] The connecting part 17 is provided with multiple anti-detachment claws 19 to prevent the contact terminal from becoming loose.

[0036] The lower end face of the housing 13 is provided with a guide groove 20, the insertion groove 14 is located in the guide groove 20, and both sides of the guide groove 20 are provided with downward guide slopes 21.

[0037] The upper end face of the plug-in part 5 is provided with a positioning groove 22 along its length direction, and the top of the plug-in groove 14 is provided with a positioning block 23 that matches the positioning groove 22.

The first horizontal portion 10, the inclined portion 11, and the second horizontal portion 12 of the elastic segment 9 form a Z-shaped bend, which can act as a "spring" to absorb some vibration in a vibration environment and ensure the stability of the connector connection.

[0042] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
