[0002] In electrical products, electrical connections between various components are generally achieved through connecting wires. When the length of the connecting wire is insufficient, it is necessary to connect two connecting wires. Existing technologies include splicing connecting wires, which use plugs and sockets to connect by inserting and pulling out, or use the elasticity of a spring to connect two connectors together. When using a snap-fit ​​method to connect two connectors, repeated snapping will reduce the connection strength between the two connectors, causing them to loosen and making it easy for the two connectors to break, thereby reducing the splicing effect of the connecting wire. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where repeated snapping reduces the connection strength between two connectors, causing them to loosen and thus reducing the splicing effect of the connecting cable. Therefore, this invention proposes a splicing connecting cable.

A conductive core is connected inside the second insulating base, and a second connecting wire is connected to the conductive core. One end of the second connecting wire passes through the second insulating base, and the conductive core is inserted into the conductive base. A fixing ring is fixedly connected to the first insulating base, and an external thread is connected to the fixing ring. A connector is sleeved on the second insulating base, and the connector is connected to the external thread. A limiting ring for limiting the position of the second insulating base is connected to the second insulating base.

[0006] Preferably, the first insulating seat and the fixing ring are an integral structure.

[0007] Preferably, the connector includes a movable cover, which is sleeved onto the second insulating base. The inner wall of the movable cover has a threaded groove that engages with the external thread. An anti-detachment ring is fixedly connected to the inner wall of the movable cover.

[0008] Preferably, a sealing ring is fixedly connected to one end of the movable cover, and the sealing ring is in contact with the second insulating seat.

[0009] Preferably, a sealing mechanism is connected between the first insulating seat and the second insulating seat, the sealing mechanism comprises a connecting ring fixedly connected to the second insulating seat, a groove is formed in the first insulating seat, the connecting ring is matched with the groove, and a hollow sealing gasket is fixedly connected in the groove and in contact with the connecting ring.

[0010] Preferably, the hollow sealing gasket is a hollow rubber sealing gasket.

[0011] The spliced connecting line has the advantages that:

[0012] When the connecting piece is in contact with the external thread, the external thread is rotated, the connecting piece is moved to the external thread, the connecting piece is in contact with the limiting ring after moving a distance on the external thread, the connecting piece extrudes the limiting ring, the limiting ring drives the second insulating seat to be in close contact with the first insulating seat, the conductive core and the conductive seat are kept in a connected state, the conductive core and the conductive seat will not be disconnected, and the splicing effect of the connecting line is improved.
