Description

Technical Field

[0001] This utility model belongs to the field of clamping device technology, and particularly relates to a clamping device for a rectangular connector. Background Technology

[0002] In the current field of electronic assembly, various types of rectangular connectors are frequently used, especially in confined operating spaces such as enclosures. Because rectangular connectors come in various shapes, conventional clamping devices are often insufficient for securing them. Furthermore, many rectangular connectors are used in space-constrained enclosures where standard clamping devices cannot be placed. When soldering rectangular connectors, it is often necessary to hold the connector with one hand while soldering with the other. Holding the connector is unstable, prone to burns, and single-handed soldering is difficult, inefficient, and compromises soldering quality. Therefore, it is necessary to explore a clamping device suitable for multi-shaped rectangular connectors, one that is compact and suitable for operation in confined spaces such as enclosures. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a clamping device for rectangular connectors that is versatile, small in size, suitable for placement in limited space, has an adjustable angle, and is easy to clamp.

[0004] To solve the above-mentioned technical problems, this utility model provides a clamping device for a rectangular connector, comprising: a base, a support plate, fastening screws, a rotating panel, a locking handle, a dovetail clip, silicone rubber, reinforcing screws, and reinforcing short connectors. The base and support plate are connected by fastening screws. The support plate has a rectangular support plate in the middle and triangular support plates on both sides. One triangular support plate has a closed through hole, and the other has an open through hole. Side shafts are provided on both sides of the rotating panel, with one shaft passing through the closed through hole and the other shaft positioned in the open through hole. The locking handle is used to lock the rotating panel and support plate at the side shafts. The dovetail clip is inserted into the reinforcing short connectors and fastened to the rotating panel by reinforcing screws. The silicone rubber is embedded inside the dovetail clip and cut after solidification. The support plate, rotating panel, and locking handle constitute an angle adjuster, allowing angle adjustment via the locking handle. The dovetail clip and silicone rubber constitute a clamping mechanism, providing clamping force without damaging the surface of the rectangular connector.

[0005] Furthermore, the base is rectangular and has threaded holes for connecting to the support plate.

[0006] Furthermore, the rectangular support plate of the support plate is provided with threaded holes for passing fastening screws through the threaded holes on the support plate and the threaded holes on the base to suspend and fix them into one piece.

[0007] Furthermore, the rotating panel is an integral panel with a rectangular panel in the middle and cylindrical shafts on both sides, and the cylindrical shafts are threaded.

[0008] Furthermore, the locking handle is hexagonal and has a cylindrical rotating arm with a built-in threaded hole.

[0009] Furthermore, when adjusting the angle, first loosen the locking handle, rotate the rotating panel to the appropriate welding angle, and then rotate the locking handle to lock it.

[0010] Furthermore, both the dovetail clip and the rotating panel have through holes on their connecting sides. After the reinforcing screw is inserted into the reinforcing short piece, it passes through the through holes to fix the dovetail clip to the rotating panel.

[0011] Furthermore, the silicone rubber fills the interior of the dovetail clip. After solidification, a cut is made in the silicone rubber from the open end of the dovetail clip along a direction perpendicular to the bottom surface of the dovetail clip. The cut in the silicone rubber is parallel to the horizontal plane of the base.

[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments, but this utility model is not limited thereto.

[0021] In the description of this utility model, it should be noted that the terms "center", "front", "rear", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1 As shown, the clamping device for the rectangular connector provided in this embodiment of the present invention includes a base 1, a support plate 2, a fastening screw 3, a rotating panel 4, a locking handle 5, a dovetail clip 6, silicone rubber 7, a reinforcing screw 8, and a reinforcing shorting piece 9.

[0023] The base 1 is rectangular, ensuring the clamp joints are open for easy worker operation and welding access to the work area. Its small size and sufficient weight ensure the stability of the rectangular connectors. The base has threaded holes for connection to the support plate 2. Preferably, the base 1 is made of galvanized iron; galvanizing is an economical and effective method of rust prevention.

[0024] The angle adjuster consists of a support plate 2, a rotating panel 4, and a locking handle 5. The base 1 and support plate 2 are fixed together by fastening screws 3. The support plate 2 has a rectangular support plate in the middle and triangular support plates on both sides. One triangular support plate has a closed through hole, and the other has an open through hole. Preferably, the support plate 2 is milled from galvanized iron. The rectangular panel of the support plate 2 has threaded holes for passing the fastening screws 3 through the threaded holes on the support plate 2 and the threaded holes on the base 1 to connect and fix them together. The rotating panel 4 is an integral panel with a rectangular panel in the middle and cylindrical shafts on both sides, with threads on the cylindrical shafts. The locking handle 5 is hexagonal and has a cylindrical rotating arm with built-in threaded holes for locking the cylindrical shafts of the rotating panel 4. When installing the rotating panel 4, first pass one side of the rotating panel 4 through the closed through hole, and place the other side of the rotating panel 4 in the open through hole. Then, simply insert the rotating panel 4 directly and secure it on both sides using the locking handles 5. When adjusting the angle, first loosen the locking handles 5, rotate the rotating panel 4 to the appropriate welding angle, and then rotate the locking handles 5 to lock it in place. The adjustment method is simple and easy to operate, and multi-angle adjustment can adapt to more welding needs.

[0025] The clamping mechanism consists of a dovetail clip 6 with embedded silicone rubber 7. A 60mm long dovetail clip is used to provide clamping force. Through holes are provided on the connecting sides of both the dovetail clip 6 and the rotating panel 4. After the reinforcing screw 8 passes through the reinforcing short connector, it then passes through the through holes to fasten the dovetail clip 6 to the rotating panel 4, thus fixing it to the angle adjuster. The dovetail clip 6 is filled with silicone rubber 7. The open ends of the dovetail clip 6 are sealed tightly with tape. After flattening, silicone rubber 7 is poured in small amounts multiple times through the gaps on the front, ensuring that the silicone rubber fills the entire interior of the dovetail clip 6. After it has completely solidified, a cut is made in the silicone rubber 7 from the open end of the dovetail clip 6 along a direction perpendicular to the bottom surface of the dovetail clip 6. The cut in the silicone rubber 7 is parallel to the horizontal plane of the base 1. The silicone rubber 7 and the dovetail clip 6 are fused together. Silicone rubber is soft, not easily damaged, has good wrapping properties, and high friction, making it suitable for various shaped rectangular connectors.

[0026] When clamping rectangular connectors, simply pinch the two tail shanks of the dovetail clip together. Once the dovetail clip has opened enough space, place the rectangular connector into the appropriate depth within the clip. Then, release the tail shanks to complete the clamping process. Adjust the clamping angle to the desired welding angle according to welding requirements. Regardless of the type of rectangular connector, the clamping force of the clip and the softness and enveloping force of the silicone rubber increase friction and gripping force, ensuring a secure and reliable clamping hold that is not easily dislodged. The clamping force is generated by the natural shape recovery of the dovetail clip itself. Appropriate clamping force will not cause connector deformation. The silicone rubber filling the dovetail clip also increases the friction between the contact surfaces of the clip and the connector, ensuring that the connector will not slip or fall off, and also preventing wear on the connector's surface markings.

[0027] This invention utilizes a dovetail clip to provide clamping force. Fitting and removing the connector is as simple as pinching the tail of the dovetail clip, making it convenient and quick. The dovetail clip is filled with silicone rubber, which is soft, durable, provides good coverage, and has high friction, making it suitable for various rectangular connector shapes. The clamping device uses silicone rubber surface contact for positioning, employs the dovetail clip for clamping, and an angle adjuster to adjust the appropriate welding angle. The base is stable and not easily moved. The overall structure is simple, easy to assemble and disassemble, and provides stable clamping.

[0028] It should be noted that the above-described embodiments are merely preferred embodiments of this utility model. For those skilled in the art, various modifications, improvements, and equivalent substitutions can be made to this utility model without departing from its principles, and such modifications, improvements, and equivalent substitutions are also considered to fall within the protection scope of the claims of this utility model.
