Description

Technical Field

[0001] This application relates to the technical field of terminal posts, and particularly to a waterproof terminal post. Background Art

[0002] Terminal posts, as indispensable connection components in electrical systems, are widely used in various circuits and electrical equipment (such as energy storage batteries). Their core function is to ensure a stable and reliable electrical connection between wires. In normal operations, to achieve this purpose, it is usually necessary to first strip the insulation layer at the end of the cable, and then wind and fasten the exposed copper conductor onto the terminal post to establish an electrical path.

[0003] However, in an environment with high humidity, the performance stability and safety of terminal posts face severe tests. Specifically, the penetration of water vapor may not only accelerate the corrosion process on the surface of the terminal post, but also penetrate to the contact interface between the copper wire and the terminal post, resulting in poor contact and even the formation of an oxide layer. This adverse condition not only weakens the reliability of the electrical connection, but also significantly increases the risks of safety hazards such as short circuits and increased resistance, thereby affecting the stable operation and service life of the entire electrical system, and there is room for improvement. Summary of the Utility Model

[0004] The purpose of this application is to provide a waterproof terminal post to solve the problem that the terminal post in the above related technologies is easily affected by water vapor and has poor waterproof performance during application.

[0005] A waterproof terminal post provided by this application adopts the following technical solutions:

[0006] A waterproof terminal post includes a base and a conductive post fixed on the base. A protective shell is fixed on the base. A wiring hole for the cable to penetrate is opened on the side surface of the protective shell, and the inner wall of the wiring hole abuts against the outer peripheral surface of the cable.

[0007] By adopting the above technical solutions, during the wiring process between the cable and the conductive post, after the insulation skin at the end of the cable is removed in advance, then control the end of the cable to penetrate the wiring hole and be electrically connected to the end of the conductive part inside the protective shell; during the application of this waterproof terminal post, use the protective shell to protect the connection between the cable and the conductive post, thereby reducing the possibility of external water vapor eroding the connection between the cable and the conductive post and enhancing the corresponding waterproof performance.

[0008] Optionally, a waterproof sealing ring is provided on the inner wall of the wiring hole, and the waterproof sealing ring is sleeved on the outer periphery of the cable.

[0009] By adopting the above technical solution, due to the installation of the waterproof sealing ring, the gap between the cable and the wiring hole is protected, reducing the possibility of external water vapor seeping into the interior of the protective shell from the gap between the waterproof sealing ring and the cable, thereby further improving the corresponding waterproof performance.

[0010] Optionally, a sealing ring groove for embedding the inner edge of the wiring hole is provided on the outer periphery of the waterproof sealing ring.

[0011] By adopting the above technical solution, when it is necessary to fix the waterproof sealing ring on the inner wall of the wiring hole, due to the setting of the sealing ring groove on the waterproof sealing ring, it is only necessary to embed the inner edge of the wiring hole into the inside of the sealing ring groove, which is convenient for the installation and fixation of the waterproof sealing ring.

[0012] Optionally, the contour shape of the protective shell is square, and the opening of the protective shell facing the base is adapted to the outer peripheral surface of the base.

[0013] By adopting the above technical solution, during the installation process of the protective shell and the base, the square contour is more efficient in space utilization, especially in occasions where regular arrangement or stacking is required. The square protective shell adapted to the base can maximize the use of space resources while ensuring the protection effect, reducing unnecessary space waste.

[0014] Optionally, an installation sink for placing the base is provided on the inner edge of the opening of the protective shell facing the base; a clamping block is fixedly provided on the inner wall of the installation sink of the protective shell, and a clamping groove for inserting the clamping block is provided on the outer side surface of the base.

[0015] By adopting the above technical solution, during the installation process of the protective shell and the base, first place the base in the installation sink on the protective shell, and then apply force to press the protective shell so that the clamping block is inserted into the inside of the clamping groove, thereby realizing the rapid assembly of the protective shell and the base.

[0016] Optionally, a guiding inclined surface is provided on the side edge of the clamping block.

[0017] By adopting the above technical solution, the clamping block can be better inserted into the inside of the clamping groove along the guiding inclined surface.

[0018] Optionally, the outer peripheral surface of the protective shell is an arc surface, a circular clamping strip is fixedly provided on the inner wall of the protective shell, and a circular groove for inserting the circular clamping strip is provided on the outer periphery of the base.

[0019] By adopting the above technical solution, due to the setting that the outer peripheral surface of the protective shell is an arc surface, the possibility of the user's hand being scratched is reduced, and it is also convenient for the user to better hold the protective shell during installation; when the protective shell and the base are assembled, the circular clamping strip on the inner wall of the protective shell is inserted into the corresponding circular groove.

[0020] Optionally, a water-absorbing cotton is arranged inside the protective shell, and an installation hole coinciding with the wiring hole is formed in the water-absorbing cotton.

[0021] By adopting the above technical solution, during the process of the waterproof terminal, the water-absorbing cotton can absorb a small amount of water vapor that enters the interior through the gap between the protective shell and the base, thereby further improving the corresponding waterproof performance.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. During the application of the waterproof terminal, the protective shell is used to protect the connection between the cable and the conductive column, thereby reducing the possibility of the external water vapor eroding the connection between the cable and the conductive column and enhancing the corresponding waterproof performance.

[0024] 2. Due to the installation of the waterproof sealing ring, the gap between the cable and the wiring hole is protected, reducing the possibility of the external water vapor seeping into the interior of the protective shell through the gap between the waterproof sealing ring and the cable, thereby further improving the corresponding waterproof performance.

[0025] 3. Due to the application of the water-absorbing cotton, during the application of the waterproof terminal, the water-absorbing cotton can absorb a small amount of water vapor that enters the interior through the gap between the protective shell and the base, thereby further improving the corresponding waterproof performance.

Four fixing holes 11 are provided on the base 1, and the user can fix the base 1 on the vertical surface of the corresponding device through screws; a protective shell 3 is installed on the base 1. Among them, wiring holes 31 for the cable to pass through are opened on the side surface of the protective shell 3, and the outer periphery of the cable abuts against the inner wall of the wiring hole 31;

[0039] Both the base 1 and the protective shell 3 are made of insulating plastic. During the wiring process between the cable and the conductive posts 2, after the insulating skin at the end of the cable is removed in advance, then the end of the cable is controlled to pass through the wiring hole 31 and be electrically connected to the end of the conductive part inside the protective shell 3.

[0040] Referring to Figure 3 and Figure 4 , the contour shape of the protective shell 3 is square, and the opening of the protective shell 3 facing the base 1 is adapted to the outer peripheral surface of the base 1; an installation sink 32 for the base 1 to be placed in is opened on the inner edge of the opening of the protective shell 3 facing the base 1; a clamping block 33 is integrally formed on the inner wall of the installation sink 32 of the protective shell 3, and a guiding inclined surface 331 is provided on the side edge of the clamping block 33. At the same time, a card slot 12 for the clamping block 33 to be inserted into is opened on the outer side surface of the base 1;

[0041] During the installation of the protective shell 3 and the base 1, the base 1 is placed in the installation sink 32 on the protective shell 3 in advance, and then a force is applied to press the protective shell 3, so that the clamping block 33 is inserted into the inside of the card slot 12 along the guiding inclined surface 331, thereby realizing the rapid assembly of the protective shell 3 and the base 1.

[0042] Refer to Figure 5 On the inner wall of the wiring hole 31, a waterproof sealing ring 4 made of rubber is provided, and a sealing ring groove 41 for the inner edge of the wiring hole 31 to be embedded is formed on the outer periphery of the waterproof sealing ring 4. After the cable penetrates through the wiring hole 31, the waterproof sealing ring 4 is sleeved on the outer periphery of the cable, and the outer peripheral surface of the cable is in tight contact with the inner wall of the waterproof sealing ring 4.

[0043] The implementation principle of the embodiment of the present application is as follows:
