Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Fig. 1 shows an electric cold-shrinkable tube with a shielding structure according to the present invention, which includes a support tube 1, wherein an outer surface of the support tube 1 is covered with a cold-shrink sleeve 2, the cold-shrink sleeve 2 includes a first cold-shrink layer 21 on an inner side and a second cold-shrink layer 22 on an outer side, and a shielding layer is installed between the first cold-shrink layer 21 and the second cold-shrink layer 22. As shown in the attached drawing 3, the shielding layer comprises grids formed by copper wires 3 in a staggered mode, a plurality of nodes 4 are installed on the grids, as shown in the attached drawing 4, the copper wires 3 penetrate through the nodes 4 at the crossing positions, each node 4 bundles two copper wires 3 together, and the phenomenon that when the shielding layer shrinks along with the first cold-shrink layer 21 and the second cold-shrink layer 22, partial grids are too sparse due to uneven shrinkage of the grids to affect the shielding effect is avoided.

As shown in fig. 2, the support tube 1 includes a head portion and a tail portion, one end of the first cold-shrink layer 21 close to the head portion is provided with a connection ring 23 surrounding the support tube 1, a node 4 on the grid close to the connection ring 23 is connected with the connection ring 23, so that the shielding layer and the first cold-shrink layer 21 are connected at a relatively fixed position, and the shielding layer is prevented from shifting to cover the cable relatively well during shrinkage.

The nodes 4 are silica gel particles, the nodes 4 comprise head nodes 41 and tail nodes 43, the head nodes 41 and the tail nodes 43 are uniformly distributed around the support tube 1 respectively, the head nodes 41 are connected with the connecting ring 23, the tail nodes 43 are close to the tail of the support tube 1, and the tail nodes 43 are located on the circumference coaxial with the support tube 1.
