DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] Example 1:

[0023] Combination Figs. 1-3 As shown, this embodiment provides an electrical contact insulation safety sleeve, including: a main module 100.

[0024] The main module 100 includes a sheath body 110, an annular member 120 fixed to the end of the sheath body 110, a fixing member 130 disposed on one side of the annular member 120, a tower-shaped rubber sleeve 140 integrally connected to one side of the sheath body 110 and communicating with the sheath body 110, a first rubber sleeve 150 fixed to one side of the sheath body 110, and a puncturing member 160 installed on the inner wall of the first rubber sleeve 150.

[0025] The sheath body 110 is made of rubber and is used to form a sealed space near the electrical contacts to prevent external impurities from adhering to the electrical contacts. The annular part 120 is fixed integrally with the sheath body 110 to increase the contact area between the sheath body 110 and the electrical contacts.

[0026] The fastener 130 is used to fix the sheath body 110 to the electrical contact, ensuring the sealing between the sheath body 110 and the electrical contact. The fastener 130 includes an adhesive layer 131 disposed on one side of the annular part 120 and a release film 132 disposed on one side of the adhesive layer 131. The adhesive layer 131 is used to bond the annular part 120 to the surface of the electrical contact, ensuring the stability of the sheath body 110 while also ensuring the sealing between the sliding sleeve body and the surface of the electrical contact. The release film 132 is used to protect the adhesive layer 131 when the adhesive layer is not in use.

[0027] The tower-shaped rubber sleeve 140 is composed of multiple rubber ring segments with different inner diameters connected to each other. The closer to the sheath body 110, the larger the inner diameter of the rubber ring segment. With the above arrangement, when the cable passes through, it is only necessary to cut the rubber ring segment on the tower-shaped rubber sleeve 140 that is smaller than the outer diameter of the cable according to the outer diameter of the cable. At this time, the tower-shaped rubber sleeve 140 can completely fit the cable surface, ensuring the sealing between the cable and the cable surface.

[0028] The first rubber sleeve 150 is filled with SF6 gas, which is used to fill the sheath body 110 to play a gas insulation role and improve the insulation performance of the sheath body 110. A sealing membrane 111 is provided on one side of the sheath body 110 to isolate the insulating gas in the first rubber sleeve 150 when the sheath body 110 is not installed.

[0029] The puncturing element 160 is used to puncture the sealing mold, opening the partition between the first rubber sleeve 150 and the sliding sleeve body, facilitating the entry of insulating gas into the sheath body 110. It includes rubber support rods 161 fixed in a ring array on the inner wall of the first rubber sleeve 150, a disc 162 fixed at the end of the rubber support rod 161, a straight rod 163 fixed on one side of the disc 162, and a cross cone 164 fixed on the other side of the disc 162. The rubber support rod 161 is used to install the disc 162, and its rubber material facilitates the movement of the disc 162. The disc 162 is used to install other components. The end of the straight rod 163 away from the disc 162 is close to the inner bottom wall of the first rubber sleeve 150. When the user presses one side of the first rubber sleeve 150, the straight rod 163 can drive the disc 162 to move. The movement of the disc 162 drives the cross cone 164 to move, so that the cross cone 164 can puncture the sealing film 111.

[0030] The working principle and usage process of this utility model are as follows: During use, the tower-shaped rubber sleeve 140 is cut according to the cable size, so that the inner diameter of the tower-shaped rubber sleeve 140 is slightly smaller than the outer diameter of the cable. The cable end is passed through the tower-shaped rubber sleeve 140 and the sheath body 110, and the cable end is fixed to the electrical contact. The sheath body 110 is moved so that it fits onto the electrical contact. The release film 132 is peeled off, and the annular part 120 is pressed tightly against the outside of the electrical contact. At this time, the adhesive layer 131 adheres the arc-shaped part to the surface of the electrical contact, ensuring the sealing of the interior of the sheath body 110. One side of the first rubber sleeve 150 is pressed, and the disc 162 is moved by the straight rod 163. The movement of the disc 162 moves the cross cone 164, puncturing the sealing film 111. At this time, the SF6 gas inside the first rubber sleeve 150 enters the sheath body 110, providing gas insulation.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
