Description

Technical Field

[0001] This utility model relates to the field of bakelite frames, specifically a pinless bakelite frame. Background Technology

[0002] Bakelite frames, also known as transformer frame frames, are an important component of the transformer structure. They mainly consist of a base, connecting cylinder, top seat, and connecting pins, and are primarily used for the installation and support of transformer coils and other components. Due to the characteristics of its material, this type of Bakelite frame has good mechanical strength, good insulation, and high heat and corrosion resistance. However, most existing Bakelite frames directly insert pins, and after the coil is assembled, the coil tail wire is wound onto these pins for soldering. This wastes manpower and reduces transformer production efficiency. Therefore, a pinless Bakelite frame needs to be designed.

[0003] According to Chinese Patent No. CN218471739U, a pinless bakelite frame is disclosed. Since there are no pins on the frame, the lead wires of the coil itself can be used as the pins of the product, saving the cost of pins on the frame and the cost of wrapping the lead wires in the later transformer winding process.

[0004] Regarding the aforementioned disclosed patent content, a base, a winding component, and a limiting component are provided, and the gantry of the limiting component can protect the coil on the winding component. However, when the limiting component is installed together with the base and the winding component, the limiting component and the winding component need to be locked with screws. Locking with screws requires the use of external tools (i.e., screwdrivers), and if the limiting component or the base and the winding component shake slightly during the locking process, it will affect the screw-in efficiency, making it inconvenient to quickly connect the winding component and the limiting component together, and reducing the installation efficiency of the limiting component, the winding component, and the base. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a pinless bakelite frame to solve the technical problem of inconvenience in quickly connecting the limiting component with the winding component and the base.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pinless bakelite frame, comprising a base and a frame, wherein the bottom of the base is provided with a snap-fit ​​assembly, and the snap-fit ​​assembly includes a sliding groove formed on both sides of the bottom of the base and a positioning groove formed on both sides of the inside of the frame, wherein a positioning plate is inserted into the positioning groove, and a slot is formed on one side of the positioning groove, wherein a spring is installed inside the sliding groove, and one end of the spring is connected to a sliding plate, wherein a slot plate is installed on one side of the sliding plate, penetrating the positioning plate and extending into the slot, and a damping pad is installed on the upper part of the inside of the sliding groove.

[0007] By adopting the above technical solution, when installing the base on the frame, the staff can first push the two push blocks, so that the push blocks drive the slide plate to move and drive the card plate to move. After the card plate moves into the positioning plate, the base can be inserted into the frame.

[0008] Furthermore, the snap-fit ​​assembly also includes through grooves on both sides of the outer surface of the base, a push block is slidably disposed inside the through groove, the through groove is connected to the slide groove, and the push block is fixedly connected to the slide plate.

[0009] By adopting the above technical solution, it is easy for staff to move the slide when pushing the pusher, thereby adjusting the position of the slide.

[0010] Furthermore, the base has a winding post at its top, and a positioning post is installed at the top of the winding post.

[0011] By adopting the above technical solution, the setting of the winding column makes it convenient for workers to wind the coil.

[0012] Furthermore, a positioning hole is provided on the upper part of the interior of the skeleton, and the positioning post is located inside the positioning hole, and the positioning post is adapted to the positioning hole.

[0013] By adopting the above technical solution, the winding column can be positioned after the positioning column is inserted into the positioning hole.

[0014] Furthermore, a lead wire groove is provided on the upper part of the interior of the skeleton, and a positioning block is fixed on the outer surface of the base, with a slot provided on the positioning block.

[0015] By adopting the above technical solution, the lead wire groove makes it convenient for workers to extend the pre-reserved cables for transformer winding from the top of the inner cavity of the frame, thereby enabling the connection of other cables.

[0016] Furthermore, the positioning plate is adapted to the positioning groove.

[0017] By adopting the above technical solution, the base can be positioned when the positioning plate is inserted into the positioning groove.

[0018] Furthermore, the card plate is adapted to the card slot.

[0019] By adopting the above technical solution, once the card plate is inserted into the card slot, the positioning plate can be clamped and limited, thus connecting the base and the frame together.

[0020] Furthermore, the bottom of the damping pad is in contact with the slide plate, and the damping pad is made of butyl rubber material.

[0021] By adopting the above technical solution, the damping pad can play a damping role, thereby improving the stability of the skateboard.

[0022] Furthermore, the slide plate is slidably connected to the slide groove, and the spring is made of austenitic stainless steel.

[0023] By adopting the above technical solution, the skateboard can slide inside the groove, thereby improving the stability of the skateboard when moving.

[0024] Furthermore, the positioning plate is fixedly connected to the base, and the top of the winding column fits into the interior of the skeleton.

[0025] By adopting the above technical solution, the winding column can be positioned to prevent it from moving arbitrarily.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model, by setting up a snap-fit ​​component, allows the operator to first push two push blocks when connecting the base and the frame. The push blocks move the sliding plate, which in turn compresses the spring and moves the snap-fit ​​plate. Once the snap-fit ​​plate is inside the positioning plate, the base can be inserted into the frame, and the positioning plate can be inserted into the positioning groove. After the positioning plate is fully inserted into the positioning groove, the two push blocks are pushed in the opposite direction, and the spring rebounds, causing the sliding plate to return to its original position. The sliding plate then moves the snap-fit ​​plate. Once the snap-fit ​​plate is snapped into the slot, the splicing between the base and the frame is completed. This method eliminates the need for screws, making the operation simple and convenient, thereby improving the efficiency of splicing between the base and the frame.

[0028] 2. This utility model features a through groove to facilitate the sliding of the push block within the groove, a positioning plate and a positioning groove to position the base so that the base can be accurately snapped into the frame, and a damping pad to improve the stability of the skateboard.

Detailed Implementation

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A pinless bakelite frame, such as Figures 1-6 As shown, the device includes a base 1 and a frame 3. The bottom of the base 1 is provided with a snap-fit ​​component 7, and the top of the base 1 is provided with a winding post 2. The top of the winding post 2 is equipped with a positioning post 5. The winding post 2 is designed to facilitate the winding of the coil by the operator. The upper part of the frame 3 is also provided with a lead wire groove 6. The outer surface of the base 1 is also fixed with a positioning block 8, and the positioning block 8 is provided with a slot 9. The lead wire groove 6 is designed to facilitate the operator to extend the cable reserved for the transformer winding from the top of the inner cavity of the frame 3, so that other cables can be connected externally.

[0040] Specifically, the snap-fit ​​assembly 7 includes a sliding groove 701 on both sides of the bottom of the base 1 and a positioning groove 705 on both sides inside the frame 3. A positioning plate 704 is inserted into the positioning groove 705. A snap-fit ​​slot 706 is opened on one side of the positioning groove 705. A spring 702 is installed inside the sliding groove 701, and one end of the spring 702 is connected to a sliding plate 703. A snap-fit ​​plate 707 is installed on one side of the sliding plate 703, which passes through the positioning plate 704 and extends into the snap-fit ​​slot 706. A damping pad 710 is installed on the upper part of the sliding groove 701. When the base 1 is installed on the frame 3, the operator can first push two push blocks 709, so that the push blocks 709 drive the sliding plate 703 to move and drive the snap-fit ​​plate 707 to move. When the snap-fit ​​plate 707 moves into the positioning plate 704, the base 1 can be inserted into the frame 3. The positioning plate 704 is adapted to the positioning groove 705. When the positioning plate 704 is inserted into the positioning groove 705, the base 1 can be positioned.

[0041] See Figures 1-5The card plate 707 is adapted to the card slot 706. When the card plate 707 is inserted into the card slot 706, the positioning plate 704 can be clamped and limited, so that the base 1 and the frame 3 can be connected together. The bottom of the damping pad 710 is in contact with the slide plate 703. The damping pad 710 is made of butyl rubber material. The setting of the damping pad 710 can play a damping role, preventing the slide plate 703 from moving at will, thereby improving the stability of the slide plate 703. The slide plate 703 is slidably connected to the slide groove 701. The spring 702 is made of austenitic stainless steel material. The slide plate 703 can slide inside the slide groove 701. The positioning plate 704 is fixedly connected to the base 1. The top of the winding column 2 is in contact with the inside of the frame 3 in order to position the winding column 2 and prevent the winding column 2 from moving at will.

[0042] Example 2:

[0043] Based on the above embodiment 1, the following structure will be set to facilitate the movement of the sliding plate 703.

[0044] Specifically, the snap-fit ​​component 7 also includes through grooves 708 on both sides of the outer surface of the base 1. A push block 709 is slidably disposed inside the through groove 708. The through groove 708 is connected to the slide groove 701. The push block 709 is fixedly connected to the slide plate 703, so that when the staff pushes the push block 709, the slide plate 703 can be moved, thereby adjusting the position of the slide plate 703.

[0045] Example 3:

[0046] Based on the above embodiment 1, the following structure will be set to improve the positioning effect of the winding column 2.

[0047] See Figures 2-5 The upper part of the skeleton 3 has a positioning hole 4, and the positioning post 5 is located inside the positioning hole 4. The positioning post 5 is adapted to the positioning hole 4. When the positioning post 5 is inserted into the positioning hole 4, the winding post 2 can be positioned.

[0048] The working principle of this utility model is as follows: First, since the winding column 2 is set to facilitate the winding of the coil, when connecting the base 1 and the frame 3 together, the operator can first push the two push blocks 709, so that the push blocks 709 drive the slide plate 703 to move. The slide plate 703 squeezes the spring 702 and drives the clamping plate 707 to move. When the clamping plate 707 moves into the positioning plate 704, the base 1 can be inserted into the frame 3, and the positioning plate 704 is inserted into the positioning groove 705. When the positioning plate 704 is fully inserted into the positioning groove 705, the positioning column 5 at the top of the winding column 2 is inserted into the positioning hole 4. Then the operator pushes the two push blocks 709 in the opposite direction, and the spring 702 rebounds to make the slide plate 703 reset and move. The slide plate 703 then drives the clamping plate 707 to move. When the clamping plate 707 is inserted into the clamping groove 706, the splicing between the base 1 and the frame 3 can be completed.

[0049] After the coil is wound, the coil's own output wire is used as the product's pin, thus eliminating the cost of inserting pins on the frame. Furthermore, the lead wire slot 6 allows workers to easily extend the pre-reserved cable from the top of the frame 3's inner cavity, enabling the connection of other cables. The positioning block 8 and slot 9 can be used to engage and limit the pin using the coil's own output wire, improving the stability of this pin's use.
