[0037] The above implementation mode is the core technical scheme of this embodiment. During the drainage wiring operation, the entire drainage wire clamp device is installed on the main cable that needs bypass drainage or branching. Specifically, the conductor part of the main cable is crimped into the accommodating groove 6 through the drainage pressure block 3. According to the drainage seat 2, there is a first drainage part 21 arranged at the accommodating groove 6. In this way, the main cable is electrically connected to the drainage pressure block 3 and the first drainage part 21 at the accommodating groove position, and then the drainage wire is inserted into the wiring hole 4 of the drainage seat 2.

During installation, the drainage wire clamp device is vertically hung on the conductor part of the main cable, or hung on the conductive ring. This conductive ring is usually electrically connected to the main cable through a puncture wire clamp to achieve electrical connection between the drainage seat and the main cable. The installation is convenient and quick, and then the bypass wire is inserted from one end of the insulating shell 1 into the wiring hole 4 of the drainage seat 2 to achieve connection, which meets the user's drainage wiring requirements in the vertical direction, increases the contact distance, simplifies the installation process, reduces the difficulty of operation, and effectively improves the construction efficiency.

[0040] The crimping assembly includes a plurality of crimping terminals 5 which are staggered in the wiring hole 4, so that the drainage wire is pressed between the plurality of crimping terminals 5 in a continuous bending shape in the threading hole. Specifically, the crimping terminal 5 is detachably connected to the drainage seat 2, and the drainage seat 2 is provided with a plurality of threaded holes corresponding to the plurality of crimping terminals 5 and connected to the wiring hole 4.

The operating end 52 is a hexagonal structure and cooperates with and abuts against the insulating housing 1. The operating end 52 can be rotated with the aid of a tool such as an inner hexagonal wrench, thereby driving the crimping terminal 5 to move. The extrusion end 51 is designed as a circular plate-like structure, which is conducive to better extruding the bypass wire in the wiring hole 4, increasing the contact surface, and making the installation force more balanced. It has good tensile resistance and good anti-loosening effect. The advantage of the above structural design is that the bypass wire is squeezed and bent by the multiple wire-pressing terminals 5 in the wire threading hole.

[0041] Combine the following Figure 1 , Figure 4-5 The specific setting method of the drainage block is described in detail:

[0042] The drainage pressure block 3 is movably arranged on the top of the other end of the insulating shell 1. Specifically, two opposite connecting plates 13 are arranged on the top of the other end of the insulating shell 1. Two connecting plates 13 are arranged oppositely with two rotating grooves 8. The drainage pressure block 3 is provided with two rotating blocks 9 rotatably connected to the two rotating grooves 8 on both sides of one end thereof. The rotating groove 8 is a C-shaped groove structure. The rotating block 9 is a square plate structure rotatably connected to the rotating groove 8, that is, the rotating block 9 is adapted to the size of the rotating groove 8. The rotating block 9 is installed into the rotating groove 8 from the C-shaped mouth of the rotating groove 8, and the installation is convenient and quick. In order to achieve the installation and fixation of the drainage pressing block 3, a fastening bolt 7 is arranged between the drainage pressing block 3 and the insulating shell 1 and the drainage seat 2. During installation, the fastening bolt is loosened first, so that the drainage pressing block 3 can be rotated at a certain angle with the rotating block 9 as the center, thereby opening the accommodating groove 6 and placing the conductor part of the main conductor into the accommodating groove 6, and then tightening the fastening bolt 7, so that the drainage pressing block 3 can firmly press the conductor part in the accommodating groove 6 under the action of the bolt tightening force to prevent loosening, thereby achieving the installation connection between the drainage wire clamp and the main conductor.

[0043] like Figure 4As shown, the accommodating groove 6 includes the first arc groove 61 arranged at the top of the insulating shell 1, and the second arc groove 62 arranged relatively to the drainage pressing block 3, the first arc groove 61 is provided with an opening structure exposing the first drainage part 21, the first drainage part 21 is provided with a first arc surface adapted to the shape of the first circular groove, the first drainage part 21 is in contact with the conductor part arranged in the accommodating groove through the first arc surface, the contact area between the first drainage part 21 and the contact part is increased, so that a perfect contact line is formed between the two, and the contact resistance is reduced. In addition, the drainage seat 2 is provided with a second drainage part 22 exposed at the top of the insulating shell 1 and located between the two rotating grooves 8, one end of the drainage pressing block 3 is rotatably abutted against the second drainage part 22, and the other end thereof is arranged relatively to the first drainage part 21, the second drainage part 22 is provided with a second arc surface in contact with the drainage pressing block 3, and the contact area between the drainage pressing block 3 and the second drainage part 22 is increased through the second arc surface. It can be known from the above structure that the drainage seat 2 is provided with a first drainage part 21 and a second drainage part 22 exposed at the top of the insulating shell 1, one end of the drainage pressure block 3 is rotated to abut against the second drainage part 22, and the other end cooperates with the first drainage part 21 to press the main cable or conductive ring in the accommodating groove. With this structural arrangement, the drainage pressure block 3 locks the main cable or conductive ring in the accommodating groove under the tightening action of the bolt, thereby respectively realizing indirect and direct contact between the drainage pressure block 3 and the first drainage part 21 and the second drainage part 22, thereby connecting the drainage pressure block 3 and the drainage seat 2 to form two current passing positions, so that the drainage pressure block 3 and the drainage seat 2 can be fully in contact with each other, have a complete contact line, reduce contact resistance, increase contact area, thereby reducing current density, improving current carrying capacity, ensuring the stability of the connection of the drainage wire clamp device, and improving the electrical service life of the product.

[0044] In order to improve the electrical connection performance of the drainage clamp device, the drainage seat 2 is made of copper material. Figure 4-5As shown, the drainage block 3 includes a block body made of insulating material and a conductor structure 30 arranged at the bottom of the block body, the conductor structure 30 includes a first copper area 31 exposed in the second arc groove 62 and matched with the first drainage part 21, and a second copper area 32 exposed at one end of the drainage block 3 and matched with the second drainage part 22, the first copper area 31 is electrically connected to the second copper area 32. Of course, the conductor structure 30 of the drainage block 3 can select other metal conductors according to the material of the drainage seat 2. The advantage of such a design is that the first copper area 31 cooperates with the first drainage part 21 to press the contact part of the conductive ring, thereby realizing the electrical connection between the first copper area 31 and the first drainage part 21, and the second copper area 32 is in direct contact with the second drainage part 22, so that the current is transmitted to the second drainage part 22 through the first copper area 31 and the second copper area 32, thereby improving the current carrying capacity. In addition, the drainage seat 2 and the conductor structure 30 are both made of metallic copper material, which has the characteristics of excellent electrical conductivity and thermal conductivity and low contact resistance, thereby improving the electrical contact performance to avoid the uneven current between the drainage pressure block and the drainage seat, thereby ensuring the high efficiency, stability and safety of power transmission and improving the product performance.

[0045] The following combination Figure 1 and Figure 4 The specific structure of the insulating shell is described in detail:

[0046] The insulating shell 1 includes a shell sleeve 11, a bottom plate 12, and an inner cavity formed by the shell sleeve 11 and the bottom plate 12 for accommodating the drainage seat 2. A limiting structure is arranged between the insulating shell 1 and the drainage seat 2. The limiting structure includes a plurality of limiting bosses 23 arranged on the side walls of both sides of the drainage seat 2, and a plurality of limiting grooves respectively arranged on the shell sleeve 11 and the bottom plate 12 and limited by the limiting bosses 23. It can be seen that the entire drainage seat 2 is plastic-wrapped by the insulating shell 1, and only a small part of the first drainage part 21 and the second drainage part 22 are exposed to cooperate with the drainage block 3, so that the insulation performance of the product is better and it is safer to use. This structural setting, through the cooperation of the limiting boss 23 and the limiting groove, plays a role in limiting the installation of the drainage seat 2 in the installation cavity, thereby improving the strength of the installation structure. At the same time, multiple wire crimping terminals 5 are threaded through the insulating shell 1 and connected to the drainage seat 2, so that when the wire crimping terminals 5 are fixed, they will apply a fastening force to the insulating shell 1 to maintain a fixed connection with the drainage seat 2. Therefore, this wire crimping terminal 5 can not only play a role in fixing the wire, but also play a role in installing and fixing the insulating shell 1 and the drainage seat 2. The installation structure is simple, the cooperation and fixation are reliable, the installation efficiency is improved, and the cost is reduced.

[0047] Further preferably, the drainage block 3 is fixedly mounted on the top of the insulating housing 1 by fastening bolts 7 and is electrically connected with the drainage seat 2. Figure 4 The drainage seat 2 is penetrated by a bolt hole connected to the fastening bolt 7, and the bolt hole is a screw hole structure. The bottom of the base plate 12 is formed with an isolation groove 15 composed of a plurality of partitions 14. One end of the fastening bolt 7 passing through the bolt hole is located in the isolation groove 15 to prevent the fastening bolt 7 from being exposed outside the base plate 12. The partition 14 and the isolation groove 15 play an insulating and isolating role for the fastening bolt 7, thereby increasing the creepage distance and improving the insulation performance of the drainage wire clamp device.

[0048] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods.
