## Abstract

The present invention discloses a multi-series connection coil without a framework, including at least two potted coils, where the multi-series connection coil without a framework is formed by winding in the following steps: step 1, first winding an enameled wire to form a first potted coil; step 2, on the basis of the first potted coil, continuing to wind a second potted coil; and step 3, continuing to wind potted coils according to requirements. The present invention is applied to a mobile phone camera, a laser head, a motor, a driver, or a smart wearable device, such as a pedometer and a VR device, and can generate a greater driving force in a case of electric power input at a low voltage, and the coil has higher sensitivity.

## Claims

### Claim 1

A multi-series connection coil without a framework, comprising at least two potted coils, wherein the multi-series connection coil is configured to be connected to an object and actuate the object to move, each of the potted coils is provided with an input end and an output end, the input ends and the output ends of the potted coils are connected in series in sequence, the multi-series connection coil, as a whole, has only one input end and one output end, and the multi-series connection coil without a framework is formed by winding in the following steps:
step 1, first winding an enameled wire to form a first potted coil;
step 2, on the basis that winding of the first potted coil is completed, continuing to wind a second potted coil, wherein an input end of the second potted coil is connected in series to an output end of the first potted coil; and
step 3, continuing to wind potted coils according to requirements, wherein input ends and output ends of the potted coils are connected in series in sequence, and the potted coils are formed by winding one enameled wire.

### Claim 2 (depends on 1)

The multi-series connection coil without a framework according to claim 1, wherein when the potted coils are wound, the first potted coil with multiple inner and outer layers is first wound by using an enameled wire, and then on the basis that winding of the first potted coil with multiple inner and outer layers is completed, a second potted coil with multiple inner and outer layers continues to be wound.

### Claim 3 (depends on 2)

The multi-series connection coil without a framework according to claim 2, wherein the coil can be wound to form a circular ring-shaped coil, an elliptical coil, a rectangular coil, a square coil, a racetrack-shaped coil, a square coil, a regular hexagon-shaped coil, or a regular octagon-shaped coil according to a requirement.

### Claim 4 (depends on 1)

The multi-series connection coil without a framework according to claim 1, wherein the coil can be wound to form a circular ring-shaped coil, an elliptical coil, a rectangular coil, a square coil, a racetrack-shaped coil, a square coil, a regular hexagon-shaped coil, or a regular octagon-shaped coil according to a requirement.

### Claim 5 (depends on 1)
