Floating terminal assembly and motor

Abstract

A floating terminal assembly is suitable for connection between an output component and an external terminal. The floating terminal assembly includes a terminal and a floating connector. The terminal is used for mating with the external terminal. The floating connector is buoyantly connected to the terminal and for connection to the output component, and can absorb any radial positional deviation when the external terminal is mated to the terminal. This prevents the floating connector from detaching from the output component due to positional displacement of the external terminal, thus avoiding motor failure and improving motor reliability.

Claims

1. A floating terminal assembly suitable for connection between an output component and an external terminal, the floating terminal assembly comprising: One terminal for connecting to the external terminal; and a floating connector, which can be floatingly connected to the terminal and is used to connect to the output.

2. The floating terminal assembly as described in claim 1, wherein, The floating connector has a first welding portion for welding to the output component, a second welding portion for welding to the terminal, and a floating connection portion connecting the first welding portion and the second welding portion.

3. The floating terminal assembly as described in claim 2, wherein, The floating connection is bent.

4. The floating terminal assembly as described in claim 3, wherein, The floating connection has multiple interconnected bent segments arranged along a non-linear path.

5. The floating terminal assembly as described in claim 4, wherein, The bent segments are respectively a first bent segment connected to the first welded portion, a second bent segment connected to the end of the first bent segment opposite to the first welded portion, and a third bent segment connected between the end of the second bent segment opposite to the first bent segment and the second welded portion. The first bent segment has a first bent arm extending from the first welded portion and a first vertical arm extending vertically from the first bent arm. The second bent segment has a second bent arm extending from the first vertical arm, a first straight arm extending horizontally from the second bent arm, and a third bent segment extending from the first welded portion. A first straight arm extends into a third curved arm. The third curved segment has a second vertical arm extending vertically from the third curved arm, a fourth curved arm extending from the second vertical arm, and a second straight arm extending horizontally from the fourth curved arm and connected to the second welded portion. The first straight arm has a first side and a second side opposite to each other. The first welded portion and the first curved arm protrude obliquely from the first side. The fourth curved arm, the second straight arm, and the second welded portion protrude obliquely from the second side. The first vertical arm and the second vertical arm are spaced apart.

6. The floating terminal assembly as described in claim 3, wherein, The terminal has a sleeve for mating with the external terminal, and the flattened length of the floating connector is more than three times the distance between the first welded portion of the floating connector and the center of the sleeve of the terminal.

7. The floating terminal assembly as claimed in claim 2, wherein, The first welded part is in the shape of a horizontal U and is used to clamp the output part.

8. The floating terminal assembly as claimed in any one of claims 1 to 7, wherein, The floating connector is a flexible component, which is formed by bending a soft copper rod or a multi-core soft copper wire multiple times.

9. A motor adapted to connect to at least one external terminal, the motor comprising: an insulating housing; at least one output member disposed in the insulating housing; and at least one floating terminal assembly as claimed in any one of claims 1 to 8, the terminal being disposed in the insulating housing for mating with the external terminal, the floating connector being buoyantly connected between the terminal and the output member.

10. The motor as claimed in claim 9, wherein, The insulating housing includes a carrier cylinder extending along an axis and defining a receiving hole around the axis. The terminal has a sleeve for mating with the external terminal. The outer diameter of the sleeve is smaller than the diameter of the receiving hole. The sleeve is buoyantly received in the receiving hole along a plurality of radial directions perpendicular to the axis.

11. The motor as claimed in claim 10, wherein, The terminal also has an outer ring disposed on the outer peripheral surface of the sleeve, and a welded portion disposed on the outer edge of the outer ring and connected to the floating connector. The bearing cylinder has a stop end face that stops the outer ring.

12. The motor as claimed in claim 9, wherein, The insulating housing includes two spaced-apart stop blocks that respectively stop the two opposite sides of the floating connector.
