Description

Technical Field

[0001] The present application relates to the field of contactor assembly tools, and in particular to a static end contact press-fitting tool. Background Art

[0002] High-voltage switches are critical components for power grid operation. The installation accuracy of their internal static contacts directly impacts the overall performance of the switch. A high-voltage switch consists of a housing and multiple contacts. The housing is made of a porcelain shell, which offers excellent insulation. Multiple static contacts are riveted into the shell. The static contacts are made of conductive material and conduct current.

[0003] The connection between the porcelain shell and the static contacts is manually riveted, with the user riveting each contact into the mounting holes in the porcelain shell. When the static contacts are secured in the porcelain shell, they form an interference fit with the mounting holes, securing them securely to the shell.

[0004] The above-mentioned related technical solutions have the following defects: after connecting the static end contacts in sequence, the user needs to manually adjust the contacts so that the positions of multiple static end contacts are aligned. When the moving electrode plate moves and abuts against the static end contact, the moving electrode plate can abut against multiple static end contacts at the same time and conduct electricity. Adjusting the height of the static end contact is time-consuming and labor-intensive, and the production efficiency is low. Utility Model Content

[0005] In order to improve the efficiency of installing static end contacts on a porcelain shell, the present application provides a static end contact press-fitting tool.

[0006] The static contact press-fitting tool provided in this application adopts the following technical solution:

[0007] A static end contact press-fitting tool comprises a sliding plate, a base, a guide rod and a pressing block. One end of the guide rod is fixed to the base, and the other end is slidably connected to the sliding plate. The pressing block is installed on the lower bottom surface of the sliding plate, and the upper surface of the base is parallel to the lower bottom surface of the pressing block.

[0008] By adopting the above technical solution, a guide rod is set on the base, a sliding plate is slidably connected on the guide rod, the porcelain shell is placed on the base, and the contacts are placed in the porcelain shell, so that the sliding plate drives the pressure block to slide vertically, the pressure block can be pressed on multiple contacts at the same time, so that the contacts are pressed into the porcelain shell and connected to each other, and the upper surfaces of multiple contacts are flush, which reduces the steps of adjusting the height of the contacts separately and improves the efficiency of installing the contacts on the porcelain shell.

[0009] Optionally, a pad is detachably connected to the base, and a plurality of jacks are provided on the pad.

[0010] By adopting the above technical solution, a through hole is opened on the pad so that the static electrode at the bottom of the porcelain shell can be inserted into the through hole, so that the pad fits the shape of the bottom of the porcelain shell. When the porcelain shell is placed on the pad, the probability of horizontal slippage of the porcelain shell on the pad can be reduced. By making the pad and the base detachable, pads of different shapes can be installed on the base, and then porcelain shells of different shapes can be placed on the pad for contact installation.

[0011] Optionally, the pressing block is detachably connected to the sliding plate.

[0012] By adopting the above technical solution, by making the pressing block detachably connected to the sliding plate, pressing blocks of different sizes can press the contacts up and down on the sliding plate, thereby facilitating the assembly of high-voltage switches of different models.

[0013] Optionally, a limiting column is provided on the base, the limiting column is arranged perpendicular to the base, and the upper end of the limiting column is used to abut against the sliding plate.

[0014] By adopting the above technical solution, a limit column is set on the base so that the limit column is vertically fixed on the base. When the sliding plate falls and the pressure block is pressed on the contact, the limit column abuts against the sliding plate, making it difficult for the sliding plate to drive the pressure block to continue falling. When the sliding plate moves too much, the limit column plays a protective role, which can reduce the chance of the pressure block damaging the porcelain shell and the contact. By setting pressure blocks of different heights on the sliding plate, the installation height of the contact in the porcelain shell can be controlled.

[0015] Optionally, a return spring is provided on the guide rod, and the return spring is sleeved on the guide rod. One end of the return spring abuts against the base, and the other end abuts against the sliding plate. A limit plate is installed at the end of the guide rod, and the limit plate is used to clamp the sliding plate.

[0016] By adopting the above technical solution, a reset spring is arranged on the guide rod, so that the reset spring can press against the sliding plate, so that the sliding plate abuts against the limit plate in a natural state. When the sliding plate falls, the sliding plate squeezes the reset spring. When the pressure block presses the contact into the porcelain shell, the sliding plate is released, and the reset spring can lift the sliding plate, thereby moving the sliding plate to a position abutting against the limit plate.

[0017] Optionally, one end of the guide rod connected to the base is threadedly connected to a fixing nut, and the guide rod passes through the base and is connected to the fixing nut.

[0018] By adopting the above technical solution, a fixing nut is set on the guide rod so that the guide rod and the base can be detachably connected. The user can remove the guide rod from the base, thereby facilitating the user to replace the pad and the pressure block.

[0019] Optionally, a slot is provided on the lower surface of the base, and the fixing nut is engaged in the slot and fixed relative to the base.

[0020] By adopting the above technical solution, a slot is provided on the lower surface of the base so that the lower end of the guide rod can pass through the base and be inserted into the slot. The fixing nut is stuck in the slot and remains fixed. When the user screws the guide rod, the guide rod can be connected to the fixing nut, thereby making it convenient for the user to install the guide rod on the base.

[0021] Optionally, a contact positioning plate is provided on the base, the contact positioning plate is horizontally covered on the porcelain shell, a plurality of grooves are opened on the contact positioning plate, and the contacts are clamped in the grooves.

[0022] By adopting the above technical solution, a contact positioning plate is provided on the porcelain shell, and the contact is set in the groove of the contact positioning plate, so that the contact can always be perpendicular to the pressure block in the porcelain shell. When the pressure block is pressed on the contact, the contact is subjected to force and riveted to the porcelain shell, reducing the chance of the contact being skewedly connected to the porcelain shell.

[0023] In summary, the beneficial technical effects of this application are:

[0024] 1. By setting a guide rod on the base, sliding a sliding plate on the guide rod, placing the porcelain shell on the base, and placing the contacts into the porcelain shell, the sliding plate drives the pressing block to slide vertically, so that the pressing block can press on multiple contacts at the same time, so that the contacts are pressed into the porcelain shell and connected to each other. The upper surfaces of multiple contacts are flush, reducing the steps of adjusting the height of the contacts separately and improving the efficiency of installing the contacts on the porcelain shell;

[0025] 2. By opening a through hole on the pad, the static electrode at the bottom of the porcelain shell can be inserted into the through hole, so that the pad fits the shape of the bottom of the porcelain shell. When the porcelain shell is placed on the pad, the probability of horizontal slippage of the porcelain shell on the pad is reduced. By making the pad and the base detachable, pads of different shapes can be installed on the base, and thus porcelain shells of different shapes can be placed on the pad for contact installation;

[0026] 3. By arranging a limit column on the base, the limit column is fixed vertically on the base. When the sliding plate falls and the pressure block is pressed on the contact, the limit column abuts against the sliding plate, making it difficult for the sliding plate to drive the pressure block to continue to fall. When the sliding plate moves too much, the limit column plays a protective role, which can reduce the chance of the pressure block damaging the porcelain shell and contacts. By arranging pressure blocks of different heights on the sliding plate, the installation height of the contact in the porcelain shell can be controlled. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] The embodiment of the present application discloses a static contact press-fitting tool, referring to Figure 1 、 Figure 2 and Figure 3 , comprising a sliding plate 1, a base 2, a guide rod 3, and a pressure block 4. The base 2 is arranged horizontally, the guide rod 3 is vertically fixed to the base 2, the sliding plate 1 is slidably connected to the guide rod 3, and the pressure block 4 is connected to the lower surface of the sliding plate 1. The upper surface of the base 2 is horizontal, and the porcelain shell 61 is placed on the upper surface of the base 2. When the contacts 62 to be installed are set in the porcelain shell 61, the sliding plate 1 can drive the pressure block 4 to press vertically downward. The lower surface of the pressure block 4 is horizontal and simultaneously abuts multiple contacts 62, so that the contacts 62 can be pressed into the porcelain shell 61 and remain flush, ensuring high installation quality.

[0034] Reference Figure 2 A pad 21 is provided on the base 2, and the pad 21 is detachably connected to the base 2 by bolts. A socket 211 is provided on the pad 21, and the socket 211 is used to insert the static electrode 63 at the bottom of the porcelain shell 61, so that the surface of the pad 21 fits with the bottom of the porcelain shell 61, so that the socket for installing the contact 62 on the porcelain shell 61 can remain vertical.

[0035] Reference Figure 1 and Figure 2 The backing plate 21 is provided with a limit post 22. The limit post 22 is vertically arranged and has a threaded bottom end. The limit post 22 is connected to the backing plate 21 through the threaded connection. When the sliding plate 1 falls vertically and abuts the upper end of the limit post 22, the sliding plate 1 is difficult to fall further, thereby limiting the position of the pressure block 4 and reducing the chance of the sliding plate 1 falling too far and damaging the ceramic shell 61 or the contact 62.

[0036] Reference Figure 1 and Figure 2, there are two guide rods 3, and the two guide rods 3 are respectively arranged on both sides of the pad 21. The upper end of the guide rod 3 passes through the sliding plate 1, and the lower end is detachably connected to the base 2 by a bolt. A limit plate 31 is provided at the upper end of the guide rod 3, and the limit plate 31 is used to clamp the sliding plate 1. A reset spring 32 is sleeved on the guide rod 3, and the lower end of the reset spring 32 abuts on the base 2, and the upper end abuts on the sliding plate 1. In the natural state, the reset spring 32 supports the sliding plate 1 so that the sliding plate 1 abuts on the limit plate 31. When the sliding plate 1 falls, the sliding plate 1 squeezes the reset spring 32, causing the reset spring 32 to contract. When the pressure block 4 presses the contact 62 into the porcelain shell 61, the sliding plate 1 is released, and the reset spring 32 can lift the sliding plate 1, so that the sliding plate 1 automatically rises.

[0037] Reference Figure 4 The base 2 has a plurality of slots 23 on its lower surface, with fixing nuts 33 secured within the slots 23. A threaded end of the guide rod 3 penetrates the base 2 and is inserted into the slots 23, allowing the fixing nuts 33 to engage within the slots 23. When the user screws the guide rod 3, the fixing nuts 33 remain fixed relative to the base 2, allowing the fixing nuts 33 to rotate relative to the guide rod 3, thereby facilitating the user's installation and removal of the guide rod 3 and replacement of the pressure block 4. By making the backing plate 21 detachably connected to the base 2 and the pressure block 4 detachably connected to the sliding plate 1, the user can use backing plates 21 of different shapes to support the porcelain shell 61 and pressure blocks 4 of different shapes to press on the contacts 62, thereby facilitating the assembly of contactors of different models.

[0038] Reference Figure 1 and Figure 3 A contact positioning plate 5 is detachably connected to the porcelain housing 61. The contact positioning plate 5 has grooves formed therein, and each contact 62 is positioned within a groove. When the porcelain housing 61 and contacts 62 are mounted on the base 2, the user horizontally places the contact positioning plate 5 on the porcelain housing 61, so that each of the contacts 62 is positioned within a groove of the contact positioning plate 5. When the pressure block 4 falls and presses against the contacts 62, the chance of the contacts 62 becoming skewed relative to the porcelain housing 61 is reduced.

[0039] The implementation principle of the embodiment of the present application is as follows: by setting a guide rod 3 on the base 2, the sliding plate 1 is slidably connected to the guide rod 3, and the user controls the sliding of the sliding plate 1 to make the pressure block 4 fall vertically and abut against the contact 62, so that the multiple contacts 62 on the porcelain shell 61 can be pressed to be flush, thereby improving the production quality of the contactor, and by setting a limit column 22 on the pad 21, the limit column 22 can be pressed against the sliding plate 1, thereby reducing the chance of the sliding plate 1 falling too much and crushing the porcelain shell 61 and the contact 62.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
