Description

Technical Field

[0001] This utility model belongs to the field of insulating silicon protection technology, specifically a high tear-resistant insulating silicone rubber sheath. Background Technology

[0002] High tear-resistant insulating silicone rubber sheaths are insulating protective sleeves made of high tear-resistant silicone rubber material. They are mainly used for insulation safety protection of the wiring terminals of power equipment such as distribution transformers, surge arresters, outdoor switches, and busbars.

[0003] Silicone rubber has excellent dielectric properties, so high tear-resistant insulating silicone rubber sheaths have good insulation effects, effectively isolating electrical equipment and live parts, and preventing electric shock accidents.

[0004] In current technologies, insulating silicone rubber sleeves are typically installed as a whole on the surface of the terminal block. However, during prolonged use, the surface is prone to cracking, making subsequent peeling of the insulating silicone rubber sleeve difficult. Therefore, a high tear-resistant insulating silicone rubber sleeve is proposed to address this issue. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a high tear-resistant insulating silicone rubber sheath.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The high tear-resistant insulating silicone rubber sheath of this utility model includes a first sheath, a second sheath is provided on the top of the first sheath, a first fixing block is fixedly connected to the end of the first sheath, a second fixing block is fixedly connected to the end of the second sheath, a slot is opened inside the second fixing block, a cavity is opened inside the second fixing block, a locking block is fixedly connected to the top of the first fixing block and slidably connected to the inside of the slot, a locking groove is opened inside the locking block, a locking block is slidably connected to the inside of the cavity, a spring is fixedly connected to the end of the locking block, and the other end of the spring is fixedly connected to the inner side wall of the cavity.

[0007] Preferably, a pull rod is fixedly connected to the end of the locking block, and a pull handle is fixedly connected to the end of the pull rod.

[0008] Preferably, an air belt is fixedly connected to the inner sidewall of the first sheath and the second sheath, and a reinforcing rib is fixedly connected to the end of the air belt.

[0009] Preferably, a copper strip is fixed to the end of the air belt, and several such strips are provided; the end of the locking block is semi-arc-shaped.

[0010] The beneficial effects of this utility model are:

[0011] This utility model provides a high tear-resistant insulating silicone rubber sheath. By placing the terminal inside the first sheath and then fastening the second sheath onto the top of the first sheath, the terminal is fitted. When the first and second sheaths are in contact, the first fixing block drives the locking block to insert into the slot. During the insertion process, the locking block is squeezed, causing it to slide into the cavity. Then, the spring is squeezed to generate elastic force. When the locking slot and the cavity are aligned, the elastic force generated by the spring pushes the locking block into the locking slot for locking and fixing. This ensures that the first and second sheaths are firmly attached together, thus protecting the terminal end.

[0012] This utility model provides a high tear-resistant insulating silicone rubber sheath. When the end skin of the first and second sheaths breaks during long-term use, the first and second sheaths need to be replaced. By pulling the handle, the pull rod is moved to the end, causing the pull rod to pull the locking block to retract into the cavity, so that the locking block slides out from the inside of the locking groove. Then, the first and second sheaths can be quickly disassembled by separating them. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1-4 This utility model provides a high tear-resistant insulating silicone rubber sheath, including a first sheath 1, a second sheath 21 on the top of the first sheath 1, a first fixing block 22 fixed to the end of the first sheath 1, a second fixing block 23 fixed to the end of the second sheath 21, a slot 32 and a cavity 33 formed inside the second fixing block 23, a locking block 31 fixed to the top of the first fixing block 22 and slidably connected to the inside of the slot 32, a locking groove 34 formed inside the locking block 31, a locking block 35 slidably connected inside the cavity 33, a spring 36 fixed to the end of the locking block 35, and the other end of the spring 36 fixed to the inner wall of the cavity 33. During operation, the rubber sheath is installed at the connection terminal. When applying the protective sleeve, the terminal is placed inside the first sleeve 1, and then the second sleeve 21 is fastened to the top of the first sleeve 1 to cover the terminal. When the first sleeve 1 and the second sleeve 21 are in contact, the first fixing block 22 drives the locking block 31 to insert into the slot 32. During the insertion process, the locking block 35 is squeezed, causing the locking block 35 to slide into the cavity 33. Then, the spring 36 is squeezed to generate elastic force. When the locking slot 34 and the cavity 33 are aligned, the elastic force generated by the spring 36 pushes the locking block 35 into the locking slot 34 to perform locking and fixing, so that the first sleeve 1 and the second sleeve 21 are firmly attached together to protect the end of the terminal.

[0024] Furthermore, such as Figures 3-4 As shown, a pull rod 41 is fixedly connected to the end of the locking block 35, and a pull handle 42 is fixedly connected to the end of the pull rod 41. During operation, when the end skin of the first protective sleeve 1 and the second protective sleeve 21 breaks after long-term use, the first protective sleeve 1 and the second protective sleeve 21 need to be replaced. By pulling the pull handle 42, the pull rod 41 is moved to the end, so that the pull rod 41 pulls the locking block 35 to retract into the cavity 33, so that the locking block 35 slides out from the inside of the lock groove 34. Then, the first protective sleeve 1 and the second protective sleeve 21 are separated to quickly disassemble them.

[0025] Furthermore, such as Figures 1-2As shown, an air belt 24 is fixedly connected to the inner sidewall of the first sheath 1 and the second sheath 21, and a reinforcing rib 25 is fixedly connected to the end of the air belt 24. During operation, the air belt 24 and the reinforcing rib 25 are installed inside the first sheath 1 and the second sheath 21. The air belt 24 protects the internal wiring, and the reinforcing rib 25 strengthens the fixation.

[0026] Furthermore, such as Figures 1-2 As shown, a copper strip 26 is fixed to the end of the air belt 24, and several of them are provided. The end of the locking block 35 is semi-arc-shaped. During operation, by installing the copper strip 26 at the end of the air belt 24, the internal structure can be supported and ventilated, thereby enhancing the heat dissipation function.

[0027] Working principle: When installing the rubber sleeve on the terminal, the terminal is placed inside the first sleeve 1, and then the second sleeve 21 is fastened to the top of the first sleeve 1 to cover the terminal. When the first sleeve 1 and the second sleeve 21 are in contact, the first fixing block 22 drives the locking block 31 to insert into the slot 32. During the insertion process, the locking block 35 is squeezed, causing it to slide into the cavity 33. Then, the spring 36 is squeezed to generate elastic force. When the locking slot 34 and the cavity 33 are aligned, the elastic force generated by the spring 36 pushes the locking block 35 into the locking slot 34 to lock and fix it, so that the first sleeve 1 and the second sleeve 21 are firmly attached together, thus protecting the end of the terminal. When the end skin of sleeve 21 breaks during long-term use, the first sleeve 1 and the second sleeve 21 need to be replaced. By pulling the handle 42, the pull rod 41 is moved to the end, causing the pull rod 41 to pull the locking block 35 to retract into the cavity 33, so that the locking block 35 slides out from the inside of the locking groove 34. Then, the first sleeve 1 and the second sleeve 21 are separated for quick disassembly. Air belts 24 and reinforcing ribs 25 are installed inside the first sleeve 1 and the second sleeve 21. The air belts 24 protect the internal wiring, and the reinforcing ribs 25 strengthen the fixation. A copper strip 26 is installed at the end of the air belts 24 to support the internal structure and allow for ventilation, thus enhancing heat dissipation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
