Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a power conductor connection device. Background Technology

[0002] Electrical engineering refers to engineering related to the production, transmission, and distribution of electrical energy. Electrical engineering requires the use of power conductors. During the inspection and maintenance of power systems, it is often necessary to cut different conductors and then reconnect them. After the existing conductors are cut, if they need to be connected, pliers are often used to peel the wire insulation off the wire. After peeling off the insulation to expose the inner core, the inner cores are twisted and knotted together. Then, electrical tape is wrapped around the conductor connection for protection.

[0003] However, this connection method has the following problems: the tape connection has poor stability and the tape is prone to falling off after long-term use, causing the wire connection to be exposed and creating safety hazards, thus bringing a lot of inconvenience to the user. Utility Model Content

[0004] The purpose of this utility model is to provide a power conductor connection device, which aims to solve the problem that the existing power conductor connection method has poor limiting stability after connection and is prone to safety hazards after long-term use.

[0005] To achieve the above objectives, this utility model provides a power conductor connection device, including a lower insulating base with a positioning post, and also includes auxiliary components;

[0006] The auxiliary components include an upper insulating seat, a connecting bolt, a strip sealing gasket, and a support member. The upper insulating seat is detachably connected to the lower insulating seat and is located above the lower insulating seat. The connecting bolt is detachably connected to the upper insulating seat and threadedly connected to the lower insulating seat, and is located on the side of the upper insulating seat closer to the lower insulating seat. The strip sealing gasket is detachably connected to the lower insulating seat and is located on the side of the lower insulating seat closer to the upper insulating seat. The support member is respectively disposed on both sides of the lower insulating seat and the upper insulating seat.

[0007] Anti-slip pads are respectively bonded and fixed to the surface of the inner semi-circular cavity of the lower insulating seat and the upper insulating seat.

[0008] The supporting member includes a supporting cylinder and a mating component. The supporting cylinder is detachably connected to the lower insulating seat and the upper insulating seat, and is located on both sides of the lower insulating seat and the upper insulating seat, respectively. The mating component is disposed inside the supporting cylinder.

[0009] The mating components include an anti-slip ring and an O-ring. The anti-slip ring is press-fitted onto the inner cavity of the support cylinder. The O-ring is detachably connected to the support cylinder and is located on the side of the support cylinder closer to the anti-slip ring.

[0010] The auxiliary component further includes an upper reflective strip and a lower reflective strip, wherein the upper reflective strip is bonded and fixed to the upper insulating base; and the lower reflective strip is bonded and fixed to the lower insulating base.

[0011] This utility model discloses a power conductor connection device. A positioning post is provided on the lower insulating base. The upper and lower insulating bases are connected by connecting bolts. A strip-shaped sealing gasket is detachably connected to the lower insulating base. Support components are respectively provided on both sides of the lower and upper insulating bases. In use, after stripping and connecting the ends of two conductors, a certain amount of electrical tape is wrapped around them. Then, the lower insulating base is placed below the connection point of the two conductors, and the upper insulating base is fixed to the lower insulating base with connecting bolts. This clamps the device to the outside of the conductor connection point. Compared with the traditional connection and limiting method using only electrical tape, this application can achieve better stability and safety, thus solving the problem of poor stability of the connection limit after existing power conductor connection methods, which easily leads to safety hazards after long-term use.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Example 1:

[0019] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the power conductor connection device. Figure 2 This is a schematic diagram of the lower insulating base 101. This utility model provides a power conductor connection device: including a lower insulating base 101 and auxiliary components. The lower insulating base 101 has a positioning post 102. The auxiliary components include an upper insulating base 103, connecting bolts 104, a strip-shaped sealing gasket 105, and a support member. The support member includes a support cylinder 107 and a mating component, which includes an anti-slip ring 108 and an O-ring seal 109. The aforementioned solution solves the problem of poor stability and potential safety hazards after prolonged use in existing power conductor connection methods. It is understood that the aforementioned solution can improve the stability of the power conductor connection and reduce safety hazards during long-term use.

[0020] In this embodiment, the lower insulating base 101 has a positioning post 102, which is used for initial positioning when the upper insulating base 103 is installed.

[0021] The upper insulating seat 103 is detachably connected to the lower insulating seat 101 and is located above the lower insulating seat 101. The connecting bolt 104 is detachably connected to the upper insulating seat 103 and threadedly connected to the lower insulating seat 101, and is located on the side of the upper insulating seat 103 near the lower insulating seat 101. The strip-shaped sealing gasket 105 is detachably connected to the lower insulating seat 101 and is located on the side of the lower insulating seat 101 near the upper insulating seat 103. The supporting members are respectively arranged on both sides of the lower insulating seat 101 and the upper insulating seat 103. The upper insulating seat 103 is provided with stepped holes to facilitate fixing it to the top of the lower insulating seat 101 by the connecting bolts 104. The lower insulating seat 101 is provided with symmetrical rectangular grooves to facilitate the direct placement of the strip sealing gasket 105. The function of the strip sealing gasket 105 is to seal the contact point between the lower insulating seat 101 and the upper insulating seat 103 after the upper insulating seat 103 and the lower insulating seat 101 are connected and fixed, thereby reducing water ingress. The semi-circular cavities of the lower insulating seat 101 and the upper insulating seat 103 are provided with clearance cavities to allow the wrapped electrical tape to pass through. The support member is used to support one side of the connection end of the two connecting wires respectively.

[0022] Secondly, anti-slip pads 106 are respectively bonded and fixed to the surface of the semi-circular cavity of the lower insulating seat 101 and the upper insulating seat 103. The anti-slip pads 106 have clearance holes that cooperate with the clearance cavity. After being set, they will improve the anti-slip ability of the wire in contact with the lower insulating seat 101 and the upper insulating seat 103, which will help improve the stability of the device clamping and fixing on the wire.

[0023] Then, the support cylinder 107 is detachably connected to the lower insulating seat 101 and the upper insulating seat 103 respectively, and is located on both sides of the lower insulating seat 101 and the upper insulating seat 103 respectively; the mating component is disposed inside the support cylinder 107. The cross-section of the support cylinder 107 is T-shaped, and the diameter of its inner circular channel is the same as the diameter of the circular channel on the side after the lower insulating seat 101 and the upper insulating seat 103 are connected. Multiple stepped holes are circumferentially formed on the mounting plate of the support cylinder 107 to facilitate fixing with bolts, and the mating component provides support and mating.

[0024] Finally, the anti-slip ring 108 is press-fitted onto the inner cavity of the support cylinder 107; the O-ring 109 is detachably connected to the support cylinder 107 and is located on the side of the support cylinder 107 near the anti-slip ring 108. A stepped hole is provided on one side of the support cylinder 107 to facilitate the press-fitting of the anti-slip ring 108. Anti-slip textures are provided in the inner circular cavity of the anti-slip ring 108. The diameter of the through hole of the anti-slip ring 108 is approximately equal to the diameter of the wire and matches the diameter of the inner circular channel of the support cylinder 107. Multiple annular mounting grooves are provided on the support cylinder 107 to facilitate the installation of multiple O-rings 109. The function of the installed O-rings 109 is to form a sealing structure between the support cylinder 107 and the wire, reducing water ingress. Sealing gaskets are provided at the mating end faces of the support cylinder 107 with the lower insulating seat 101 and the upper insulating seat 103 on both sides for sealing.

[0025] When using this utility model to solve the problem of poor stability and potential safety hazards after prolonged use of existing power wire connection methods, the following steps are taken: First, the support cylinder 107 is fitted onto one connecting wire and slid to one side of the connection point. The other wire is similarly fitted with the support cylinder 107 and slid to the same side of the connection point. After stripping and connecting the ends of the two wires, a certain amount of electrical tape is wrapped around them. Then, the lower insulating seat 101 is placed below the connection point of the two wires, and the wrapped portion of the electrical tape is placed into the clearance cavity of the lower insulating seat 101. Finally, the upper insulating seat... The positioning hole on 103 mates with the positioning post 102, and is fixed to the lower insulating seat 101 by the connecting bolt 104, thereby fixing the device clamp to the outside of the wire connection. Finally, the support cylinder 107 is slid to abut against the two end faces of the lower insulating seat 101 and the upper insulating seat 103, and fixed by bolts. Compared with the traditional single electrical tape for connection and limiting, the structure of this application can achieve better stability and safety, thereby solving the problem of poor limiting stability after connection of existing power wire connection methods, which can easily cause safety hazards after long-term use.

[0026] Example 2:

[0027] like Figure 3 As shown, where Figure 3 This is a schematic diagram of the overall structure of the power conductor connection device. Based on the first embodiment, this utility model provides a power conductor connection device, and the auxiliary components further include an upper reflective strip 201 and a lower reflective strip 202.

[0028] The upper reflective strip 201 is bonded and fixed to the upper insulating base 103; the lower reflective strip 202 is bonded and fixed to the lower insulating base 101. An mounting groove is provided on the upper insulating base 103 to facilitate direct bonding and fixing of the upper reflective strip 201. Three upper reflective strips 201 are provided. Similarly, an mounting groove is provided on the lower insulating base 101 to facilitate direct bonding and fixing of the lower reflective strip 202. Three lower reflective strips 202 are also provided.

[0029] In this embodiment, since both the upper reflective strip 201 and the lower reflective strip 202 are made of reflective material, after installation, they can provide warnings for the fixed position of the device and provide warning markings for the wire connection position, thereby further improving the safety of use.
