[0020] The utility model relates to a kind of distribution equipment terminal post insulating cover of quick installation, to provide a kind of terminal post insulating cover, which is convenient to install, wide application range and has good insulation performance.The design of the insulating cover considers the convenience of installation, the reliability of insulation performance and the simplicity of maintenance. The following is a detailed description of the specific implementation of the utility model.

[0021] As Figure 1 , Figure 2 , Figure 3 And Figure 4As shown, the utility model discloses a distribution equipment terminal post insulating cover is by the insulating cover body 1 of outside and install several cross bite parts 2 of insulating cover body 1 inner wall are formed. This embodiment selects four cross bite parts 2, and the inner wall of insulating cover body 1 is equipped with four snap -fitted parts with the bayonet 2.4 of vertical arm 2.3 one end of cross bite part 2.4 adaptation, these snap -fitted parts are the key components in the design of insulating cover body 1, and their main role is to fix cross bite part 2, ensure its stability and reliability in the use process. The vertical arm 2.3 one end of each cross bite part 2 is designed with the bayonet 2.4, and these bayonets 2.4 are accurately matched with the snap -fitted parts on the inner wall of insulating cover body 1, through the interaction of bayonet 2.4 and snap -fitted part, realize the quick installation and fixed of cross bite part 2. Four snap -fitted parts are along the center of the cylindrical symmetry, make cross bite part 2 more balanced when installing, and help to reduce the deflection and uneven stress in the installation process. The insulating cover body 1 of the utility model discloses is designed as a hollow cylinder, and the size diameter is 10 centimeters wide, the busbar is 30 centimeters long, and the wall thickness is 0.3 millimeters. The hollow cylinder not only is convenient for processing, but also can fit the shape of the wire when installing, and provides good protection effect. The insulating cover body 1 is made of insulating elastic material, which not only ensures the insulating property of the insulating cover, but also gives it good elasticity and restoring force. During installation, the insulating cover can closely fit the wire, providing better insulation and protection effect. In addition, the use of elastic material also makes the insulating cover effectively absorb energy when subjected to external impact, reducing damage to the internal wire. The busbar of insulating cover body 1 is provided with an open slot 1.1, that is, a straight line opening is opened on the busbar of insulating cover body 1, and the open slot 1.1 is linearly distributed along the full length of the busbar of insulating cover body 1. The utility model utilizes the contraction ability around the center of the hollow cylindrical object after unilateral linear sectioning during the recovery process, thereby achieving the purpose of installing a self-tightening insulating cover on the distribution equipment terminal post. This self-tightening design not only improves the convenience of installation, but also enhances the fixing effect of the insulating cover. On both sides of the open slot 1.1 in the middle part of the insulating cover body 1, one mounting plate 1.2 is arranged. The mounting plate 1.2 is a U-shaped plate, the plane where the mounting plate 1.2 is located is perpendicular to the plane where the open slot 1.1 is located, and the two mounting plates 1.2 are in the same plane. A circular hole is arranged on the mounting plate 1.2 for fixing an arc-shaped opening tool. The arc-shaped opening tool is used to pull apart the insulating cover body 1 at the open slot 1.1, so that the insulating cover body 1 forms an open hollow cylinder. This design allows the insulating cover body 1 to easily fit the distribution equipment terminal post, greatly simplifying the installation process. During installation, first, use the arc-shaped opening tool to pull apart the insulating cover body 1 at the open slot 1.1 to form an open hollow cylinder. Then, fit the open hollow cylinder to the distribution equipment terminal post. Next, remove the arc-shaped tool, and use the contraction ability around the center of the insulating cover body 1 during the recovery process to achieve self-tightening contraction installation.This mounting method not only improves the mounting efficiency, but also ensures the close fit between the insulating cover and the terminal post, and improves the insulation effect.

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the inner wall of the insulating cover 1 is provided with four cross-shaped engaging parts 2, which are evenly distributed on the inner wall of the insulating cover 1 and are distributed symmetrically along the center of the insulating cover 1. The symmetrically distributed cross-shaped engaging parts 2 help the insulating cover to maintain balance during installation, reducing the deflection and uneven force during installation, thereby improving the stability and durability of the insulating cover. The symmetrically distributed cross-shaped engaging parts 2 can evenly disperse the force during installation, avoiding deformation or damage of the insulating cover due to excessive local force, ensuring that the insulating cover can stably protect the terminal post for a long time. The cross-shaped engaging part 2 is 15 cm long and is linearly distributed along the central axis of the insulating cover 1, with one end being 12 cm away from the opening of the insulating cover 1 and the other end being 13 cm away from the insulating cover 1. The cross-shaped engaging part 2 includes a horizontal arm 2.2 and a vertical arm 2.3, and the connection between the horizontal arm 2.2 and the vertical arm 2.3 is located in the middle lower position, so that the cross-shaped engaging part 2 can provide stronger clamping force when fixing the wire. The vertical arm 2.3 of the cross-shaped engaging part 2 is provided with a bayonet 2.4 at one end to connect with the inner wall of the insulating cover 1, and the bayonet 2.4 is in the shape of a cuboid. The bayonet 2.4 is designed to allow the cross-shaped engaging part 2 to be easily detached from the inner wall of the insulating cover 1, and the detachable design of the cross-shaped engaging part 2 not only facilitates installation and maintenance, but also expands the application range of the insulating cover. The number of cross-shaped engaging parts 2 installed can be selected according to needs, and two or three cross-shaped engaging parts 2 can be selected for installation, thereby adapting to wires of different diameters and increasing the versatility and flexibility of the insulating cover. In addition, this design also facilitates the replacement of damaged engaging parts without replacing the entire insulating cover, greatly reducing maintenance costs and time. The horizontal arm 2.2 of the cross-shaped engaging part 2 is in the shape of a circular arc, and the horizontal arms 2.2 of the four cross-shaped engaging parts 2 form an inner circle with a diameter smaller than that of the insulating cover 1. The diameter of the inner circle is 3 cm, and the center of the inner circle is the same as the center of the insulating cover 1. This design allows the cross-shaped engaging part 2 to closely fit the wire, providing good fixing effect. The circular arc-shaped horizontal arm 2.2 design not only allows the cross-shaped engaging part 2 to better adapt to the shape of the wire, but also provides better fit during installation, thereby improving the fixing effect of the insulating cover. In addition, the circular arc-shaped horizontal arm 2.2 can provide better cushioning when subjected to external force, reducing damage to the wire. The horizontal arms 2.2 of the four cross-shaped engaging parts 2 are provided with gaps. The gap design between the horizontal arms 2.2 helps to dissipate heat from the wire, effectively preventing overheating of the wire from affecting the performance of the insulating cover. Overheated wires can cause the performance of the insulating material to degrade or even be damaged, and the presence of gaps provides the necessary space for heat dissipation, ensuring the stability and reliability of the insulating cover in high-temperature environments. The gap between the horizontal arms 2.2 also provides convenience for the installation and adjustment of the wire. During installation, the wire can easily pass through the horizontal arms 2.2 of the cross-shaped engaging part 2 through the gap, reducing the difficulty and time of installation.At the same time, the gap also allows the wire to be fine-tuned after installation to ensure optimal fixing effect and contact performance. The vertical arm 2.3 of the cross-shaped bite part 2 has a plurality of protrusions 2.1 at one end close to the center of the circle, and the cross-section of the protrusions 2.1 is approximately triangular with the tip pointing towards the inner center, so that the protrusions 2.1 can effectively bite the wire and provide stronger fixing force. These protrusions 2.1 are linearly distributed along the full length of the cross-shaped bite part 2. The protrusions 2.1 are made of rigid material, which hard-bites the wire and fixes the insulating cover on the wire. This design enhances the friction between the cross-shaped bite part 2 and the wire, providing stronger fixing force to prevent the insulating cover from sliding or shifting on the wire, ensuring the stability and safety of the terminal post. In practical application, this fixing method can effectively prevent the insulating cover from shifting due to vibration, impact or other external factors, thereby protecting the terminal post from damage. The material between the horizontal arm 2.2 and the bayonet 2.4 of the cross-shaped bite part 2 is made of elastic material, and the other parts are made of rigid material. This combination of materials not only improves the structural strength of the insulating cover, but also reduces stress concentration in the rigid part through the cushioning effect of the elastic material, prolonging the service life of the insulating cover and improving its impact resistance.

[0023] One end of the insulating cover body 1 is provided with a notch 1.3, which is located 212 cm away from the cross-shaped bite part 2.3, and the notch 1.3 is in the shape of a circular arc. The notch 1.3 is used to accommodate the components of the terminal post, so that the utility model can be installed at the connection part of the post head and the wire. The notch 1.3 can provide the necessary space for the protruding part of the terminal post, avoiding installation difficulties or damage due to insufficient space. This design increases the adaptability of the insulating cover, allowing it to adapt to terminal post components of different shapes, improving the flexibility of installation. The straight line where the open slot 1.1 is located coincides with the symmetry axis of the notch 1.3, and the straight line design of the open slot 1.1 allows the insulating cover to maintain stable contraction ability during expansion and recovery.

[0026] If necessary, the number of cross-shaped bite parts 2 can be adjusted to accommodate wires of different diameters. Select the appropriate number of cross-shaped bite parts according to the diameter of the wire to ensure that the insulating cover can closely fit the wire.

[0027] 2. Fix the arc-shaped opening tool.

[0028] Use the arc-shaped opening tool to fix it in the mounting hole of the two mounting plates 1.2 of the insulating cover body 1, ensuring that the tool is stable and will not slide.

[0029] 3. Expand the insulating cover body 1.

[0030] The insulating cover 1 is pulled apart at the opening slot 1.1 by an arc-shaped opening tool, so that the opening slot 1.1 is expanded to the maximum, forming an open hollow cylinder. During the pulling-apart process, the force is controlled to avoid damage to the insulating cover 1.

[0031] 4. The insulating cover 1 is fitted to the terminal post.

[0032] The open hollow cylindrical insulating cover 1 is fitted to the terminal post of the power distribution equipment, ensuring that the insulating cover closely fits the terminal post. During the fitting process, attention is paid to aligning the various components of the terminal post to ensure that the insulating cover can completely cover the terminal post.

[0033] 5. Fix the wire.

[0034] The protrusions 2.1 of the cross-shaped engagement part 2 are aligned with the wire to achieve fixation of the wire. The protrusions 2.1 are ensured to have good contact with the wire, providing sufficient fixing force to prevent the insulating cover from sliding or shifting on the wire.

[0035] 6. Remove the arc-shaped tool.

[0036] After ensuring the fixation of the wire, the arc-shaped tool is removed from the insulating cover 1. The self-tightening contraction installation is achieved by the contraction ability of the insulating cover 1 around the center during the recovery process.

[0037] 7. Check the installation effect.

[0038] After installation, the fixation of the insulating cover is carefully checked to ensure that there is no looseness or deviation. The contact surface of the insulating cover with the terminal post is checked to ensure that there is no gap or void to ensure good insulation effect.

[0039] During installation, attention is paid to the contact of the protrusions 2.1 of the cross-shaped engagement part 2 with the wire to ensure that the protrusions 2.1 can effectively engage the wire, providing sufficient fixing force to prevent the insulating cover from sliding or shifting on the wire, ensuring the stability and safety of the terminal post. Since the cross-shaped engagement part 2 is symmetrically distributed along the center of the insulating cover, during installation, it is ensured that each cross-shaped engagement part is uniformly stressed to avoid skewing and uneven stress, thereby improving the stability and durability of the insulating cover.
