Abstract
Description
Technical Field
[0001] This utility model relates to the field of connectors, and more specifically, to a connector with a locking structure. Background Technology
[0002] Chinese patent application CN119062634A, entitled "Direct Insertion Locking Mechanism Female End, Direct Insertion Locking Mechanism, and Direct Insertion Locking Connector," discloses a connector with a locking mechanism. The main feature is a toggle ring with axial displacement within the female end housing. An axially displaced sliding ring is also provided between the toggle ring and the female end housing. Several ball-load locking elements are located on the outer periphery of the sliding ring's front end. The toggle ring has a locking surface for radially pressing against the locking elements and a clearance groove located behind the locking surface. The male end housing has a locking groove that engages with the ball-load. When the male end is inserted into the female end, it pushes the sliding ring axially, ultimately inserting and connecting the ball-load, which then engages with the locking groove. Unlocking is achieved by pushing the toggle ring until the clearance groove on the toggle ring is above the locking elements. Since the unlocking method involves pushing the toggle ring towards the male end with one hand and then pulling the male end out in the same direction with the other hand, the unlocking operation is not very user-friendly and is quite cumbersome. Utility Model Content
[0003] To address the shortcomings of the existing technology, this utility model provides a connector with a locking structure that conforms to unlocking operation habits.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A connector with a locking structure includes a male end and a female end. The female end has at least two elastic hooks evenly arranged around an axis inside. The rear end of each hook is fixedly connected to the female end, and the front end of each hook is a hook portion that is suspended. The female end also has an unlocking ring that can rotate to push each hook to deform and cause its hook portion to move and expand radially synchronously. The male end also has a conical surface that pushes each hook to deform and cause its hook portion to move and expand radially synchronously when inserted. The male end also has a groove that can accommodate the hook portion after insertion.
[0006] In a further improvement, the female end includes an inner shell and an outer shell, the outer shell being detachably fitted and fixedly connected to the inner shell, and the rear end of the hook being fixedly connected between the outer shell and the inner shell.
[0007] In a further improvement, the unlocking ring includes a push ring, an operating ring, and several connecting rods. The push ring is located inside the female end and has a number of push surfaces, each used to push the corresponding hook to deform radially, the same as the number of hooks. The operating ring is sleeved outside the female end. The connecting rods are evenly arranged around the axis of the female end and pass through the outer shell, with their inner and outer ends fixedly connected to the operating ring and the push ring, respectively.
[0008] In a further improvement, the pushing ring is provided with protrusions evenly distributed around the axis, the same number as the number of hooks, and the pushing surface is an inclined surface provided on the protrusions.
[0009] In a further improvement, the protrusion is provided with a locking hole, the inner end of the connecting rod is inserted into the locking hole with an interference fit, and the outer end of the connecting rod is detachably locked to the operating ring by screws.
[0010] As a further improvement, the inner shell is also provided with a limiting groove, and the pushing ring is rotatably placed in the limiting groove.
[0011] As a further improvement, the outer surface of the unlocking ring is also provided with anti-slip texture.
[0012] In summary, the beneficial effects of this utility model are as follows: When using this utility model, inserting the male end towards the female end causes the conical surface on the male end to deform the hooks, causing the hooks to expand radially and synchronously. Continue pushing the male end until the groove aligns with the hooks. At this point, the hooks reset, allowing the hooks to enter the grooves and locking the male and female ends. To unlock, rotating the unlocking ring causes the hooks to deform, expanding radially and synchronously, disengaging the hooks from the grooves and unlocking the device. Then, simply pull out the male end. This utility model, by rotating the unlocking ring and then pulling out the male end, facilitates the unlocking operation, which is more in line with practical operating habits and makes the unlocking process more convenient.

[0021] Reference Figure 1 and Figure 2 A connector with a locking structure includes a male end 1 and a female end 2. The female end 2 has at least two elastic hooks 3 evenly arranged around an axis inside. The rear end of each hook 3 is fixedly connected to the female end 2, and the front end of each hook 3 is a hook portion 31 that is suspended. The female end 2 is also provided with an unlocking ring 4 that can rotate and push each hook 3 to deform, causing its hook portion 31 to move and expand radially synchronously. The male end 1 is also provided with a conical surface 11 that pushes each hook 3 to deform and its hook portion 31 to move and expand radially synchronously when inserted. The male end 1 is also provided with a groove 12 that can accommodate the hook portion 31 to enter and be hooked after insertion.
[0022] In one embodiment, such as Figure 1 and Figure 2As shown, the female end 2 includes an inner shell 21 and an outer shell 22. The outer shell 22 is detachably sleeved and fixedly connected to the inner shell 21. The inner shell 21 and the outer shell 22 can be connected by threads or locked with locking screws. In this structure, the rear end of the hook 3 is provided with a protrusion 32, and a corresponding groove is provided on the inner side of the outer shell 22. The protrusion 32 is engaged in the groove. By utilizing the connection between the inner shell 21 and the outer shell 22, the protrusion 32 is prevented from falling out of the groove, thus fixing it between the outer shell 22 and the inner shell 21.
[0023] The number of hooks 3 should be at least two. The more hooks there are, the more secure the hook will be, but the greater the resistance to unlocking will be. Therefore, it is preferable to use three hooks 3.
[0024] In one embodiment, such as Figure 1 and Figure 2 As shown, the unlocking ring 4 includes a pushing ring 41, an operating ring 42, and several connecting rods 43. The pushing ring 41 is located inside the female end 2 and has the same number of pushing surfaces as the hooks 3, each used to push the corresponding hook 3 to deform radially. The operating ring 42 is sleeved on the outside of the female end 2. The connecting rods 43 are evenly arranged around the axis of the female end 2, and each connecting rod 43 passes through the outer shell 22 and is fixedly connected to the operating ring 42 and the pushing ring 41 at its inner and outer ends, respectively. Preferably, there are three connecting rods 43. The unlocking ring 4 is composed of the pushing ring 41, the operating ring 42, and several connecting rods 43, which facilitates production and installation.
[0025] In one embodiment, such as Figure 2 As shown, the pushing ring 41 has the same number of protrusions 411 evenly distributed around the axis as the hooks 3. The pushing surface is an inclined surface 412 on the protrusion 411. A locking hole is also provided on the protrusion 411. The inner end of the connecting rod 43 is inserted into the locking hole with an interference fit. The outer end of the connecting rod 43 is detachably locked to the operating ring 42 by screws. During unlocking, pushing the operating ring 42 to rotate causes the pushing ring 41 to rotate synchronously through the connecting rod 43. This causes each inclined surface 412 to act synchronously on the corresponding hook 3, thereby pushing the hook portion 31 of the hook 3 to move radially synchronously and expand to complete the unlocking. After the external force is removed during unlocking, the elastic force of the hook 3 acts on the inclined surface 412, causing the pushing ring 41, connecting rod 43, and operating ring 42 to synchronously reset and rotate.
[0026] In one embodiment, such as Figure 1 As shown, a limiting groove is also provided on the inner housing 21, and the pushing ring 41 is rotatably placed in the limiting groove. The limiting groove limits the pushing ring 41, ensuring that it does not swing during rotation. Additionally, as shown... Figure 2As shown, the outer circular surface of the unlocking ring 4 is also provided with anti-slip texture 421. The anti-slip texture 421 can improve the friction and make it easier for the fingers to rotate the operating ring 42.
[0027] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
