[0019] The present invention is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more specific. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0020] like Figure 1-Figure 3 As shown, the utility model discloses a cable plug device, including an outer snap sleeve 1 and an inner snap sleeve 2 connected by threads, wherein the outer snap sleeve 1 has an inner thread 101, and the inner snap sleeve 2 has an outer thread 201. The interior of the outer snap sleeve 1 and the inner snap sleeve 2 is a cavity, in which a plug core 3 is provided, and a tapered portion 301 is provided at each end of the plug core 3, and the outer surface of the tapered portion 301 and the inner wall of the cavity are provided to accommodate the cable core. First, two cables are placed in the cavities of the outer snap sleeve 1 and the inner snap sleeve 2 respectively, and the plug core 3 is also placed in the cavity. During the process of tightening the threads, the tapered portion 301 of the plug core 3 cooperates with the side wall of the cavity to press the cable, so that the two cables can be connected conveniently and quickly, the device has low use cost, and the connection is reliable and effective. Preferably, the plug core 3 is made of conductive material, and more preferably, the same conductive material as the cable.

[0021] like Figure 2 and Figure 3 As shown, the middle of the plug core 3 is a cylindrical portion 303, and two tapered portions 301 are respectively arranged on both sides of the cylindrical portion 303. The cavities of the outer snap sleeve 1 and the inner snap sleeve 2 both include a tapered area and a cylindrical area, wherein the cylindrical area is located in the middle position of the connection, roughly where the thread is located. The outer diameter of the cylindrical portion 303 matches the inner diameter of the cylindrical area, so that when connected, the plug core 3 is further limited by the cylindrical area and the cylindrical portion 303, so that it is in the middle position of the connection, and the two tapered portions 301 are just located in the cavities on both sides.

[0022] like Figure 1 and Figure 3 As shown, a plurality of clamping blocks 302 are provided on the conical portion 301, and a plurality of clamping slots 4 are provided in the cavities of the outer clamping sleeve 1 and the inner clamping sleeve 2. Preferably, the clamping blocks 302 are wedge-shaped blocks. During the connection process, at least part of the clamping blocks 302 are embedded in the clamping slots 4, and the clamping blocks 302 and the clamping slots 4 cooperate with each other, so that the outer clamping sleeve 1 and the inner clamping sleeve 2 can only be clamped continuously in the middle direction, and will not move in the reverse direction to withdraw, so that the device connection is tighter and the connection cable is more secure.

[0023] The specific installation steps include: first, stripping the insulation skin of the cable core, the stripping length is at least able to be placed in the cavity of the outer snap sleeve 1 and the inner snap sleeve 2; then, the outer snap sleeve 1 and the inner snap sleeve 2 are respectively inserted into the two cables to be connected, and the cable core is wrapped around the plug core 3; finally, the cables are tightly connected by continuously tightening the outer snap sleeve 1 and the inner snap sleeve 2.

[0024] In summary, the cable plug-in device of this embodiment can connect two cables quickly and conveniently, and the device cost is low.
