Technical Field
[0001] The utility model relates to the technical field of power terminals, in particular to a power terminal for a floating board-to-board connector. Background Art
[0002] Floating board-to-board connectors are connectors used to connect two circuit boards. They generally include a male socket and a female socket (also called a male connector and a female connector) that plug into each other. A floating mechanism is provided in the female socket, which can eliminate the misalignment of the circuit board during the assembly process when plugged into the male socket, and reduce the force between the connector and the circuit board. Therefore, it is widely used for electrical connections in vibration environments.
[0003] As board-to-board (BTB) connectors are widely used in different fields, the demand for connectors is not only limited to signal transmission, but some users also have the demand for high current transmission. At the same time, the use of a floating structure can absorb the misalignment of the male and female sockets, and can offset some welding tolerances when multiple board-to-board connectors are used on the same substrate. The floating structure can also enable the connector to be used normally in a vibration environment. In addition, with the miniaturization of electronic equipment in recent years, the connector installed on the circuit substrate is required to be miniaturized.
[0004] However, the existing power terminal structure is too simple. After the power terminal is applied to the floating board-to-board connector, the magnitude of the force required for the floating board-to-board connector to float cannot be reduced. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technical solutions, the utility model provides a power terminal for a floating board-to-board connector, which can effectively solve the technical problem that the existing power terminal structure is too simple and the power terminal cannot reduce the force required for the floating board-to-board connector to float after being applied to the floating board-to-board connector.
[0006] The utility model solves the technical problem by adopting a technical solution: a power terminal for a floating board-to-board connector, comprising a first power terminal holding portion, a power terminal welding portion arranged at the bottom end of the first power terminal holding portion, a first power terminal elastic portion arranged at the top end of the first power terminal holding portion, a second power terminal holding portion arranged at one end of the first power terminal elastic portion, a second power terminal elastic portion arranged at the top end of the second power terminal holding portion, and a power terminal contact portion arranged at the top end of the second power terminal elastic portion;
[0007] The first power terminal elastic portion is composed of a plurality of metal strips, the first power terminal elastic portion includes a first bending section, a first straight section and a second bending section which are formed in sequence, and a bending portion is provided between the second power terminal retaining portion and the second power terminal elastic portion.
[0008] Preferably, the power terminal welding portion is formed on one side of the first power terminal holding portion, and the first power terminal elastic portion is formed on a side of the first power terminal holding portion away from the power terminal welding portion.
[0009] Preferably, the bent portion is bent toward one side of the elastic portion of the first power terminal.
[0010] Preferably, the first bending section is formed at one end of the first power terminal elastic portion close to the first power terminal retaining portion, and the second bending section is formed at one end of the first power terminal elastic portion close to the second power terminal retaining portion.
[0011] Preferably, there is an inclination angle between the front end of the first bending section and the first power terminal holding portion, and one end of the first bending section connected to the first straight section is in an arc shape.
[0012] Preferably, one end of the first bending section close to the first power terminal retaining portion is in a straight line shape, and one end of the first bending section connected to the first straight line section is in an arc shape.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The elastic portion of the first power terminal is composed of multiple metal strips, and the elastic portion of the first power terminal includes a first straight section, a first bent section and a second bent section. The first bent section is formed at one end of the first straight section close to the first power terminal retaining portion, and the second bent section is formed at one end of the first straight section close to the second power terminal retaining portion. Therefore, elastic deformation can occur when the movable shell and the fixed shell are displaced relative to each other. The setting of the bent section makes the force arm of the elastic portion of the first power terminal longer, which can effectively reduce the force required for floating.
