Description

Technical Field

[0001] This invention relates to the field of cable electrical installation tools, and specifically to a tail clamp locking and fixing device. Background Technology

[0002] Circular electrical connectors are widely used in my country's industrial sector, particularly in the production of cable network electrical components. During cable assembly, after cable welding, the tail accessory needs to be installed and locked. If either the plug or the tail accessory is not secured during the tightening of the connector tail clip, the insulating core and the tail accessory can rotate simultaneously, preventing effective locking. Currently, connector mating sockets are used to lock the tail accessory, or flat-nose pliers are used to increase friction between the insulating core and the metal outer ring. However, mating sockets are diverse, and the friction from flat-nose pliers can easily deform the connector's metal outer ring, leading to difficulties in material coordination, operational challenges, and significant quality risks.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1-7 As shown, the present invention provides a tail clamp locking device, including a locking frame 1. A rotating mechanism 2 for rotational adjustment is provided at the bottom of the locking frame 1. A support mechanism 3 for support and extension adjustment is provided at the bottom of the rotating mechanism 2. An angle locking mechanism 4 for controlling the opening and closing angle is provided on the outer side of the support mechanism 3. The rotating mechanism 2 includes a connecting component located at the bottom of the locking frame 1, and a fastening component for rotational locking is provided on the outer side of the connecting component. The support mechanism 3 includes a bearing component located at the bottom of the connecting component. An extension component is slidably connected inside the bearing component, and a clamping component for protectively clamping a connector is provided at one end of the extension component. The angle locking mechanism 4 includes a snap-fit ​​component located on the outer side of the extension component, and an elastic component is provided at the inner end of the snap-fit ​​component.

[0031] The locking bracket 1 is mainly used as a fixed support point for the entire device and is used for external clamping and locking fasteners. The rotating mechanism 2 can rotate freely in the unlocked state to control the position of the support leg 37 embedded in the lower part, i.e., the support mechanism 3. The extension amount can be freely adjusted according to the actual use needs to meet the matching distance of the connector groove position. The angle locking mechanism 4 controls the extension amount and the opening and closing angle when opening, and ensures the stability when the series is fixed by elastic tension.

[0032] like Figure 3 As shown, the connecting assembly includes a fixed shaft 21 fixedly installed at the bottom of the locking frame 1. The outer side of the bottom of the fixed shaft 21 is provided with connecting grooves 25 at equal intervals to realize auxiliary rotation operation, while the connecting grooves 25 are used to rotate the adapter bracket 31.

[0033] like Figure 3 As shown, the fastening assembly includes a rotating shaft 22 rotatably connected to the outside of the fixed shaft 21. A threaded hole 23 is provided on one side of the rotating shaft 22. The cooperation between the fixed shaft 21 and the rotating shaft 22 can achieve a rotation effect, thereby adjusting to the required directional position. The threaded hole 23 is used to thread-fit the fixed shaft 21.

[0034] in addition:

[0035] like Figure 3 As shown, a locking device 24 is connected to the internal thread of the threaded hole 23. One end of the locking device 24 is pressed against the outside of the fixed shaft 21. The fixed shaft 21 is tightened to secure the fixed shaft 22. When rotation is not required, the fixed shaft 21 and the rotating shaft 22 can be fixed to prevent them from rotating freely or rotating due to external force.

[0036] like Figure 5 As shown, the load-bearing component includes a bracket 31 rotatably connected inside the connecting groove 25. A support leg 32 is fixedly installed at one end of the bracket 31. The bracket 31 is used to connect the support leg 32 and to adjust the angle when needed, thereby adjusting to the required opening and closing state. The support leg 32 provides support for the operation and is used to adapt to the telescopic bracket 34.

[0037] The extension assembly includes a telescopic bracket 34 slidably connected inside the support leg 32. A connecting plate 35 and positioning holes 36 equidistantly spaced from the outer surface of the telescopic bracket 34 are fixedly installed on the outer surface of the connecting plate 35. The telescopic bracket 34 can be extended and adjusted by slidingly adapting to the support leg 32 to extend to the required height position. The positioning holes 36 are used to adapt to the insertion of the connecting rod 44, thereby enabling control over the opening and closing angles between the three sets of telescopic brackets 34.

[0038] The outer surface of the support leg 32 is provided with a limiting hole 33, and the connecting plate 35 slides inside the limiting hole 33. The limiting hole 33 is mainly used to slide and adapt to the connecting plate 35 to ensure that it slides stably in a predetermined direction.

[0039] The clamping assembly includes a foot 37 fixedly mounted on the bottom of the telescopic bracket 34. A rubber pad 38 is fixedly mounted on the upper surface of the foot 37. The foot 37 clamps and locks the connector. The added rubber pad 38 prevents the tail clamp locking device from scratching the connector. The telescopic bracket 34 can freely adjust the extension amount to meet the matching distance of the connector groove position.

[0040] like Figure 6 As shown, the snap-fit ​​assembly includes a support rod 41 inserted into the positioning hole 36. A circular plate 42 is fixedly installed at the inner end of the support rod 41. The support rod 41 is used to support the internal components, and the circular plate 42 can slide inside the support rod 41 and can compress the spring 43 when subjected to tensile force.

[0041] like Figure 7 As shown, the elastic component includes a spring 43 welded to the outside of the circular plate 42. A connecting rod 44 is welded to the end of the spring 43 away from the circular plate 42. The support rod 41 and the connecting rod 44 are slidably connected through each other. The connecting rod 44 is used to directly insert into the corresponding required positioning hole 36 after adjustment to complete the control of the opening and closing angle. The spring 43 is designed to be elastic, so that the connecting rod 44 can be driven by the elastic pull to control the opening angle between the three sets of telescopic brackets 34.

[0042] The tail clip locking device is an effective device for fixing and locking the connector tail clip. The device is made of stainless steel parts and is fixed by tightening screws. The tail clip locking device is suitable for most connectors with sufficient positioning point openings. It has a simple structure, reasonable design, is easy to use and has high applicability.

[0043] The locking frame 1 is the fixed fulcrum of the entire device and is used for external clamping and locking fasteners. The fixed shaft 21 and the rotating shaft 22 are rotatably connected to ensure free rotation and change between them, and control the position of the embedded support leg 37. The locking device 24 can lock the fixed shaft 21 and the rotating shaft 22 to control their rotation. The open bracket 31 is used to control the opening and closing angle of the three support legs 32.

[0044] Among them, the three support legs 32 are equipped with telescopic brackets 34, which can be freely adjusted to meet the fitting distance of the connector groove position;

[0045] The support leg 32 and the telescopic bracket 34 are connected by a support rod 41 and the components connected to both ends to control the extension amount and the opening angle of the open bracket.

[0046] The support leg 37 and the telescopic bracket 34 are integrated into one piece.

[0047] The working principle of this invention is as follows: In actual use, firstly, according to the required pre-fixation during rotation, take out the locking device 24, align it with the threaded hole 23, and rotate the locking device 24 so that the thread extends into the inside of the threaded hole 23. Continue to rotate until one end of the locking device 24 is pressed against the outside of the fixed shaft 21, thereby ensuring that the fixed shaft 21 and the rotating shaft 22 will not rotate arbitrarily. When rotation adjustment is required, loosen the locking device 24 in advance and release it from the pressing state. Then rotate the rotating shaft 22 to the required directional position to stop the rotation. Then, rotate the locking device 24 to achieve the pressing and fixing effect as described above to complete the rotation operation.

[0048] Subsequently, when it is necessary to adjust the opening angle of the support connection, the three sets of support legs 32 are rotated in advance, which drives the bracket 31 and its connected parts to rotate together. After rotating to the preset angle, the bracket is removed and the rotation is stopped. Then, it is necessary to extend and adjust according to the requirements. The rotation connection of the bracket 31 can be adjusted by damping rotation. When the required opening angle is adjusted, it is necessary to ensure that the clamping connector distance meets the requirements. At this time, the extension and adjustment operation can be performed.

[0049] During the extension adjustment process, the telescopic bracket 34 needs to be pulled in advance. The telescopic bracket 34 and the support leg 32 are interference-fitted. It will slide inside when an external force, namely a pulling force or a pushing force, is applied. When adjusting and extending outward, an outward pulling force needs to be applied. Then, the telescopic bracket 34 is pulled and the connected parts are moved together to the preset extension position, so that the tail clamp locking and fixing device can be used in the subsequent process.

[0050] To ensure that the opening angle of the three sets of telescopic brackets 34 does not change and to maintain stable support and connection, the angle locking mechanism 4 is used for locking. The support rod 41 is taken out and placed between the three sets of telescopic brackets 34. At the same time, the connecting rods 44, which are symmetrically arranged at both ends, are pulled outward. When the connecting rods 44 are pulled outward, the circular plate 42 will slide inside the support rod 41, and the spring 43 will be compressed during the sliding process, further extending the connecting rods 44 at both ends outward. Then, the connecting rods 44 are inserted into the corresponding positioning holes 36 and the outward pulling force is released. At this time, the telescopic brackets 34 at both ends can be reinforced and connected according to the elastic contraction of the spring 43, and the required opening angle is fixed. The operation is now complete. The tail clip locking device can then be completed by the bottom support foot 37 and the rubber pad 38. The rubber pad 38 provides protection to prevent scratches or damage to the connector.

[0051] In summary, the arrangement of the rotating mechanism 2, the support mechanism 3, and the angle locking mechanism 4 results in a simple, lightweight, and convenient structure with high applicability. It is suitable for most connectors with suitable positioning point openings and can be adjusted according to actual needs. The rotating mechanism 2 ensures free rotation and control of the position of the embedded support 37. The three sets of support mechanisms 3 not only support the top rotating mechanism 2 but also control the opening angle of the support as needed and freely adjust the extension length of the support based on its extension effect. The angle locking mechanism 4 is mainly used to lock the opening and closing angles of the three sets of support mechanisms 3, ensuring that they are fixed and locked after opening and closing, preventing free movement.

[0052] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
