## Abstract

A portable wire stripping and crimping machine, comprising: a base having a housing and an operation front. On the base, from left to right of the operation front, a feeding module, a wire stripping module, a crimping module, and an insulation stripping module are provided, respectively, the crimping module being connected to the feeding module and its bottom side being connected to the wire stripping module; and an operation control module having multiple switch buttons provided on a control side connected to the operation front. The crimping module consists of a first motor reducer, a toggle mechanism, and a crimping mechanism. The wire stripping module consists of a second motor reducer, a wire clamping mechanism, and a die cutter mechanism. The insulation stripping module consists of a third motor reducer and an insulation stripping mechanism.

## Claims

### Claim 1

A portable wire stripping and crimping machine, comprising:
a base having a housing and an operation front, on the base, from left to right of the operation front, a feeding module, a wire stripping module, a crimping module, and an insulation stripping module are provided, respectively, the crimping module being connected to the feeding module and a bottom side of the crimping module being connected to the wire stripping module; and
an operation control module having multiple switch buttons provided on a control side connected to the operation front;
wherein, the crimping module is composed of a first motor reducer, a toggle mechanism, and a crimping mechanism, the first motor reducer driving both the toggle mechanism and the feeding module, and the toggle mechanism being connected to the crimping mechanism to enable the crimping mechanism to move up and down;
wherein, the wire stripping module includes a second motor reducer, a wire clamping mechanism, and a die cutter mechanism, the second motor reducer driving both the wire clamping mechanism and the die cutter mechanism;
wherein, the insulation stripping module includes a third motor reducer and an insulation stripping mechanism, the third motor reducer driving the insulation stripping mechanism;
wherein, the operation control module is electrically coupled to the first motor reducer, the second motor reducer, and the third motor reducer.

### Claim 2 (depends on 1)

The machine according to claim 1, wherein the wire clamping mechanism includes a crank and a linear guide mechanism, and wherein the second motor reducer drives the crank which is linked to the linear guide mechanism for a forward and backward movement, and the tail end of the linear guide mechanism is connected to the die cutter mechanism.

### Claim 3 (depends on 1)

The machine according to claim 1, wherein the insulation stripping mechanism is a rotary insulation stripping machine.

### Claim 4 (depends on 1)

The machine according to claim 1, wherein the operation control module is connected to a wireless transmission system.

### Claim 5 (depends on 1)

The machine according to claim 1, wherein the crimping mechanism is provided with an upper mold and a lower mold, wherein a bottom side of the lower mold is connected to the wire stripping module.

### Claim 6 (depends on 5)

The machine according to claim 5, wherein the toggle mechanism comprises multiple connecting levers connected to each other, wherein one of the connecting levers is connected to the upper mold, and these connecting levers are driven by the first motor reducer, and wherein one of these connecting levers moves the upper mold both up and down.

### Claim 7 (depends on 6)

The machine according to claim 6, wherein the upper mold crimps a terminal component unit from top to bottom to couple with a conductor of a wire between the upper mold and the lower mold.

### Claim 8 (depends on 1)

The machine according to claim 1, wherein the first motor reducer drives the feeding module to propel a terminal component unit from the left side of the operation front to the right side of the operation front to the position of the crimping mechanism.

### Claim 9 (depends on 8)

The machine according to claim 8, wherein the insulation stripping mechanism is a wire stripping plier which is driven by the third motor reducer to open and close and which cuts an outer insulation of a wire.

### Claim 10 (depends on 9)

The machine according to claim 9, wherein the second motor reducer drives the clamping mechanism to clamp the wire and drives the die cutter mechanism to cut an inner insulation of the wire, then the second motor reducer drives the linear guide mechanism to move backward to pull apart the inner insulation of the wire.
