Description

Technical Field

[0001] This utility model relates to the field of locking component connection technology, specifically to a split-type non-riveting and non-detachable locking component, which can be applied to scenarios where plugs and sockets of connectors, electrical connectors, etc., require threaded locking. Background Technology

[0002] In the field of electrical connectors, threaded locking is a common locking method. However, many existing electrical connectors do not have locking accessories fixed to the connector, making them prone to falling off or being lost during transportation and use. To solve this problem, anti-fall-off locking components have emerged, but most of these components use a riveting structure. In practical applications, some electrical connectors use a plastic base as their shell, and a riveting structure can easily damage the shell, rendering it unusable. Furthermore, some locking components are split cylindrical structures, and riveting on cylindrical structures is very difficult and carries the risk of rivets shifting and falling off. Therefore, a locking component that does not require riveting is needed to address the issue of some connectors not being able to use a riveting structure. Utility Model Content

[0003] The purpose of this utility model is to provide a split-type locking assembly that does not require riveting or falling off, in order to solve the problems of easy falling off of locking accessories and easy damage to the base caused by riveting in the prior art.

[0004] The split-type non-riveting and non-detaching locking assembly of this utility model includes a base, a threaded guide pin, a sleeve, a washer, and an internal hexagonal handle;

[0005] The threaded guide pin is inserted into the accessory hole of the base, and the sleeve and the washer are installed in sequence. After the threaded end of the threaded guide pin is coated with thread-locking adhesive, it is screwed into the internal hexagonal shank for connection and fixation. The inherent properties of the thread-locking adhesive ensure that the locking assembly is not riveted or detached, and that parts can be manually replaced in case of damage to the locking assembly, thus improving maintainability.

[0006] As a further preferred embodiment, the head of the hexagonal socket handle is of hexagonal shape, which can be used to tighten or unlock using an hexagonal wrench. The hexagonal socket handle is provided with an observation hole in the radial direction to observe the application of thread adhesive, thereby avoiding the phenomenon that the threaded guide pin is not coated with thread adhesive.

[0007] The internal hexagonal shank is threadedly engaged with the threaded guide pin tail thread. The threaded guide pin tail thread is coated with thread-locking adhesive. After the thread-locking adhesive solidifies, the internal hexagonal shank and the threaded guide pin are fixed together as one unit.

[0008] The head of the internal hexagonal handle has an internal hexagonal structure.

[0009] As a further preferred embodiment, the sleeve abuts against the rear end of the base.

[0010] As a further preferred embodiment, the washer is located between the sleeve and the internal hexagonal shank.

[0011] As a further preferred embodiment, the tail thread of the threaded guide pin is engaged with the internal thread of the internal hexagonal shank.

[0012] The head of the threaded guide pin is located inside the accessory hole of the base.

[0013] As a further preferred embodiment, the accessory hole of the base is a through hole.

[0014] As a further preferred embodiment, the threaded guide pin, sleeve, washer, and internal hexagonal shank are coaxially arranged.

[0015] As a further preferred embodiment, the thread adhesive is applied to the outer surface of the threaded tail thread of the threaded guide pin.

[0016] Compared with the prior art, the present invention has at least the following significant advantages:

[0017] First, this invention uses a threaded adhesive fixing method instead of the traditional riveting structure, which avoids damage to the base and is especially suitable for electrical connectors with plastic bases.

[0018] Secondly, the sleeve and washer in this invention reduce the left and right swaying of the threaded guide pin and prevent loosening after locking, thereby improving the stability and reliability of the locking assembly.

[0019] Finally, this invention achieves the locking assembly's non-riveting and non-detachment function through the structure of the base, internal hexagonal shank, and threaded guide pin tail thread, using thread-locking adhesive for fixation. The inherent properties of the thread-locking adhesive allow for component replacement of the locking assembly, improving maintainability. Attached Figure Description

[0031] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "in an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any way in one or more embodiments.

[0032] The following is a detailed description of a split-type, non-riveting, non-detaching locking component according to the present utility model patent, with reference to the accompanying drawings.

[0033] As shown in Figures 1 to 7, the split-type non-riveting and non-detaching locking assembly of this utility model includes the following components:

[0034] Base 2, on which an accessory hole 2-1 is provided;

[0035] The threaded guide pin 1 is inserted into the accessory hole 2-1 of the base 2. The insertion depth of the threaded guide pin is controlled by the stepped shaft 1-1 of the threaded guide pin and the accessory hole.

[0036] Sleeve 3 is sleeved on the threaded guide pin 1 and located at the rear end 2-2 of the base;

[0037] Washer 4 is fitted onto the threaded guide pin 1 and located after the sleeve 3;

[0038] The internal hexagonal shank 5 is screwed into the threaded guide pin 1-2 at the tail end, and the threaded guide pin 1-2 at the tail end is coated with thread-locking adhesive 6. After the thread-locking adhesive 6 solidifies, it fixes the internal hexagonal shank 5 and the threaded guide pin 1 into one piece. The head 5-1 of the internal hexagonal shank 5 is of internal hexagonal structure and can be tightened using a conventional GB / T 5356-2 internal hexagonal wrench 11. The internal hexagonal shank 5 is provided with an observation hole 5-2 in the radial direction for observing the application of the thread-locking adhesive.

[0039] like Figure 1 As shown, this is the overall structure 10 of the split-type non-riveting and non-detaching locking assembly.

[0040] like Figure 4 As shown, the threaded guide pin 1 is inserted into the accessory hole 2-1 of the base 2. The depth of the threaded guide pin is controlled by the stepped shaft 1-1 of the threaded guide pin and the accessory hole. Then, the sleeve 3 and washer 4 are sequentially installed into the threaded guide pin at the rear end 2-2 of the base. The sleeve then applies thread-locking adhesive 6 to the threaded guide pin's tail thread 1-2. Figure 1 As shown, screw the handle 5 into the end of the threaded guide pin and tighten it, then wait for the thread sealant to solidify. This way, the locking assembly is fixed to the base without using a riveting structure, preventing it from falling off during transportation or use. Simultaneously, rotating the handle 5 causes the threaded guide pin to rotate, achieving subsequent locking and unlocking functions. Figure 5 As shown, the head 5-1 of the handle adopts an internal hexagonal structure, which can be tightened with a standard GB / T 5356-2 internal hexagonal wrench 11. At the same time, there are two observation holes 5-2 in the radial direction of the handle, which can be used to observe the application of thread sealant and prevent the thread guide sleeve from being uncoated.

[0041] like Figure 6 As shown, this plug 9 with a split, non-riveting, and non-detachable locking assembly can be inserted and locked to the threaded fixed-end locking assembly 8 and the socket 7 in a simultaneous insertion and locking manner. Figure 7As shown, during locking, the handle 5 is turned using an Allen wrench 11. The handle rotates the threaded guide pin, engaging it with the locking assembly 8 at the fixed end. This achieves thread locking. During this process, the sleeve 3 prevents the threaded guide pin from wobbling, and the washer 4 prevents loosening after the connector is locked. When separating the plug and socket, the handle is also turned using an Allen wrench 11. In special cases where disassembly of the locking assembly is required, the connection between the handle and the threaded guide pin 1 can be heated to over 200°C or higher to remove the thread sealant. Afterward, the locking assembly can be removed by turning the handle with an Allen wrench.

[0042] During installation, firstly, insert the threaded guide pin 1 into the accessory hole 2-1 of the base 2. The insertion depth of the threaded guide pin is controlled by the stepped shaft 1-1 of the threaded guide pin and the accessory hole. Then, at the rear end 2-2 of the base, sequentially slip the sleeve 3 and washer 4 onto the threaded guide pin 1. Next, apply threadlocker 6 to the threaded end thread 1-2 of the threaded guide pin, and screw the hexagonal shank 5 into the threaded end thread 1-2 of the threaded guide pin, allowing the threadlocker 6 to solidify. In this way, the locking assembly is fixed to the base 2 without using a riveting structure, preventing it from falling off during transportation or use. Simultaneously, the rotation of the hexagonal shank 5 rotates the threaded guide pin 1, achieving subsequent locking and unlocking functions.

[0043] When it is necessary to connect and lock the plug 8 with the locking assembly to the socket 10 with the threaded fixed-end locking assembly 8, use an Allen wrench 11 to turn the Allen handle 5. The Allen handle 5 drives the threaded guide pin 1 to rotate, causing it to engage with the fixed-end locking assembly 8, ultimately achieving thread locking. During this process, the sleeve 3 ensures that the threaded guide pin 1 does not wobble left or right, and the washer 4 prevents loosening after the connector is locked. When separating the plug and socket, simply use an Allen wrench 11 to turn the Allen handle 5. In special cases where it is necessary to disassemble the locking assembly, the connection between the Allen handle 5 and the threaded guide pin 1 can be heated to a temperature of 200°C or higher to degrade the thread adhesive 6. After that, the locking assembly can be removed by turning the Allen wrench 11 to turn the Allen handle 5.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
