CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims all benefits accruing under 35 U.S.C. § 119 from China Patent Application No. 201910876917.0, filed on Sep. 17, 2019, in the CNIPA, the content of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to the technical field of an electrical connection of two or more electrical wires, and in particular, to a wire connecting device and a method thereof.

BACKGROUND

A lamp holder can be used for assembling a bulb, which is electrically connected to the bulb, so that the bulb can illuminate. A power supply connected to the lamp holder usually includes three wires, which are respectively a live wire, a neutral wire and a ground wire. At present, for connecting the power supply with the lamp holder, an electrical connector such as a copper element can be used to connect a core wire of one electrical wire with a core wire of another electrical wire by crimping. However, before the crimping process, it is necessary to manually cut off an insulating housing of the electrical wire to be connected, and then crimp the core wires of the two electrical wires with the electrical connector, and finally integrally encapsulate a rubber on the crimped core wires.

Although the above method can realize an electrical connecting of the two electrical wires, a stability of manually cutting the insulating housing is poor, a cutting position may be unfixed, a cutting area may be uncontrollable, and even the core wire may be cut off, which is hard to realizing the electrical connection of the two electrical wires. In addition, it cannot be automated, resulting in low production efficiency.

SUMMARY

The present disclosure provides a wire connecting device and a method thereof.

The wire connecting device for connecting and electrically communicating a first electrical wire and a second electrical wire can include: an electrical connector having a first end, a second end, and a concave portion between the first end and the second end, wherein the concave portion is configured for accommodating a second core wire of the second electrical wire; and a connecting member cooperating with the electrical connector and configured for guiding the first end and the second end of the electrical connector connected with the first electrical wire.

In one embodiment, the connecting member can be provided with a lancet configured for piercing a first insulating housing of the first electrical wire to contact with a first core wire of the first electrical wire. A first guiding surface extending respectively from both sides of the lancet can be configured for guiding the first end and the second end of the electrical connector.

In one embodiment, the first guiding surface can have an arc shape.

In one embodiment, the first end of the electrical connector can be provided with at least one first spinous structure and the second end of the electrical connector can be provided with at least one second spinous structure.

In one embodiment, the at least one first spinous structure and the at least one second spinous structure may not be opposite to each other and may be a mismatch with each other.

In one embodiment, the connecting member can be provided with a transitional surface and a second guiding surface respectively extending outwards from the first guiding surface in order.

In one embodiment, the second guiding surface, the transitional surface and the first guiding surface can be configured for guiding the first end and the second end of the electrical connector to be deformed and crimped, resulting in electrically communicating the first end and the second end of the electrical connector with the first core wire.

In one embodiment, the wire connecting device can further include a pressing member, the pressing member and the connecting member are separated on opposite sides of the electrical connector. The pressing member can be configured for pressing the electrical connector and making the first end and the second end of the electrical connector guide by the second guiding surface, the transitional surface and the first guiding surface.

In one embodiment, the wire connecting device can further include a driving member configured for pushing the connecting member or the pressing member to make the electrical connector and the connecting member move towards each other.

A wire connection method using the wire connecting device can include:

providing the electrical connector and the connecting member;

placing the second core wire of the second electrical wire on the concave portion of the electrical connector, and placing the first electrical wire on an opening of the concave portion of the electrical connector; and

engaging the electrical connector and the connecting member to make the first end and the second end of the electrical connector inserting into a first insulating housing of the first electrical wire, resulting in the first electrical wire and the second electrical wire electrically communicated by the electrical connector.

In the present disclosure, the wire connecting device and the method thereof have the following advantages.

The electrical connector is configured for directly connecting the second core wire of the second electrical wire with the first core wire of the first electrical wire, thereby avoiding a step of manually cutting off the insulating housing and the problems caused by cutting off the insulating housing. It can improve an efficiency and stability of the electrical connection of the two electrical wires. At the same time, the wire connecting device can be mechanically operated, which can realize an automation of the electrical connection of the two electrical wires.
