[0002] Electrical wires are one of the most common conductive materials in daily life, widely used in homes, industries, communications, automobiles and many other fields. When using electrical wires, it is unavoidable to connect two sections of wire to ensure the extension of the wire length and to ensure the normal connection and use of the wire.

[0003] Existing wire splicing methods typically involve removing the insulation sheath at the splice point, then wrapping the conductors of the two wires together, and finally covering the wrapping area with insulating tape. This method results in poor reliability of the splice and is prone to tape aging, leading to a shorter lifespan for the joint.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a wire splicing connector that, by incorporating a wire splice connector, ensures that when wires need to be connected, the connector clamps and connects the wires without the need for adhesive tape, thus guaranteeing the reliability of the wire connection.

[0012] In one embodiment, the side wall of the insulator is provided with a groove, the protective sleeve is slidably connected to the inside of the groove, and a thrust spring is provided between the protective sleeve and the groove to push the protective sleeve outward.

[0013] This utility model provides a wire splicing connector, comprising: a connecting inner core with metal contacts at both ends for clamping and fixing wires; the metal contacts connect the internal metal wires of the wires, ensuring the continuity of the wires and enabling normal connection; a connecting body connects the two metal contacts, ensuring conductivity between them, thus effectively achieving conductivity between the metal contacts and the wires; and clamping shells at both ends of the connecting inner core, which, when adjusted, further clamp the metal contacts to the wires, ensuring reliable connection between the metal contacts and the wires.

[0018] See Figure 1 , Figure 2 and Figure 3 This utility model provides a wire connection and installation head, which includes a connecting inner core 3 with metal contacts 37 at both ends for clamping and fixing the wire. The metal contacts 37 connect the internal metal wires of the wire, thereby ensuring the continuity of the wire and achieving normal connection. A connecting body is provided between the two metal contacts 37 to ensure the conductivity between the two metal contacts 37, thus effectively achieving the conductivity between the metal contacts 37 and the wire. A clamping shell 1 is provided at both ends of the connecting inner core 3. Adjusting the clamping shell 1 further clamps the metal contacts 37 to the wire, ensuring that the connection between the metal contacts 37 and the wire can be made reliable.

[0019] In one embodiment, combined with Figure 2 , Figure 3 and Figure 4 To ensure the external protection of the connecting core, an insulator 34 is provided on the outside of the connecting body. The insulator 34 can be made of non-conductive materials such as plastic. The insulator 34 is fitted onto the outside of the connecting body. It can be formed by fitting or by directly melting the insulator 34 onto the outside of the connecting body. The outside of the insulator 34 has a hexagonal part, which facilitates the twisting control of the connecting body and ensures the relative rotation effect between the clamping shell 1 and the connecting body. The outer walls on both sides of the connecting body have threaded parts 33. The inside of the clamping shell 1 has threaded holes 11 corresponding to the threaded parts 33. The clamping shell 1 is screwed onto the threaded parts 33. By rotating the clamping shell 1, the position of the clamping shell 1 on the connecting body can be adjusted to ensure that the wire is clamped and connected by adjusting the position of the clamping shell 1, thereby effectively connecting the wire.

[0020] In addition, the end of the metal contact 37 of this utility model is provided with a guide bevel 36, and the inner wall of the pressing housing 1 is provided with a pressing bevel 13 corresponding to the guide bevel 36. The pressing housing 1 moves inward to press the metal contact 37 in the axial direction.

[0021] When in use, by fitting the clamping bevel 13 and the wire bevel together, when the clamping housing 1 rotates and moves inward, the clamping bevel 13 will press and deform the guide bevel 36 inward, and by deforming the clamping metal contact 37 inward, it will clamp the exposed part of the wire's metal wire, thereby realizing the connection between the wire and the metal contact 37 and ensuring the normal conductive connection of the wire.

[0022] Furthermore, to ensure proper insertion and compression of the wire, a wire groove 32 is provided inside the metal contact 37. The wire is inserted into the wire groove 32. Before compression, the end of the wire is stripped to expose the metal wire. Then, the exposed part is inserted into the wire groove 32. To ensure the compression effect on the wire, there are interlocking metal protrusions 31 on the inner wall of the wire groove 32. The metal protrusions 31 compress the wire. The two metal protrusions 31 exert force to compress the metal wire of the wire, thus completing the connection between the metal contact 37 and the wire. The metal contact 37 is made of elastic metal material, ensuring that the compression housing 1 can effectively compress and deform the metal contact 37.

[0023] In one embodiment, to protect the area between the clamping housing 1 and the hexagonal portion, a protective sleeve 2 is slidably provided on the side wall of the hexagonal portion. The protective sleeve 2 abuts against the end of the clamping housing 1. The protective sleeve 2 and the clamping housing 1 cooperate to form a protective housing and an insulating layer to prevent leakage. The clamping housing 1 and the protective sleeve 2 are made of insulating materials to ensure the insulating effect of the insulating layer. The clamping housing 1 and the protective sleeve 2 cooperate to form an insulating shell layer that protects the communicating inner core 3. A groove 35 is provided on the side wall of the insulator 34. The protective sleeve 2 is slidably connected to the inside of the groove 35. A thrust spring 4 is provided between the protective sleeve 2 and the groove 35 to push the protective sleeve 2 outward, ensuring that the protective sleeve 2 can always abut against the end of the clamping housing 1 to prevent leakage areas.

[0024] When using, combine Figures 1-4 When wires need to be connected, first strip the outer shell from the end of the wire, then insert the wire into the fixing hole 12, and then insert the wire into the wire groove 32. At the same time, put the clamping shell 1 on the connecting body, and twist the clamping shell. The clamping shell moves towards the middle of the connecting body. The clamping bevel 13 on the clamping shell cooperates with the guide bevel 36, pressing the metal contact 37 to deform and bend inward, so that the metal protrusion 31 inside the metal contact 37 clamps the wire. At this time, the metal contact 37 clamps and connects the wire. When the clamping shell 1 is fixed, it is grounded with the protective sleeve 2, so as to provide insulation protection for the outside of the connecting core, ensuring normal connection and connection of the wire, and at the same time protecting the outside of the connector to prevent leakage and other phenomena.

[0025] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
