Description

Technical Field

[0001] This utility model relates to the field of wearable device technology, and in particular to a snap-fit ​​connector and lanyard structure. Background Technology

[0002] The widespread adoption of wearable devices has spurred the development of their supporting accessory industry. Among these, the lanyard, as a key component, directly impacts user safety and experience through its reliable connection to the device itself. To enable detachable functionality, connecting buckles have become standard equipment on lanyard assemblies.

[0003] In the technological development of connectors, the initial approach was a direct plug-in structure. This structure utilizes the elastic deformation of the plastic component to achieve locking. While simple and inexpensive, it suffers from inherent disadvantages such as insufficient locking force and low tensile strength, making the connector prone to detachment. Furthermore, it requires a significant non-axial force during separation, which is inconvenient for users and reduces their experience. To overcome these shortcomings, an improved push-button connector was developed. However, this structure has a complex internal structure, cumbersome assembly processes, and high costs.

[0004] Therefore, there is an urgent need for a snap-fit ​​connector and a hanging rope structure to solve the above-mentioned technical problems. Utility Model Content

[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] like Figures 1-6 As shown, this embodiment provides a snap-fit ​​connector, including a connector base 1, a snap-fit ​​fastener 2, and a fastener 3. The connector base 1 has a mounting groove 11 and a connector hole 12, which communicates with the mounting groove 11. A fastening baffle 13 is provided on the side wall of the connector hole 12. The connector base 1 is used to connect a first rope 100. The fastener 3 is fixedly connected to the mounting groove 11. The snap-fit ​​fastener 2 has a limiting buckle 21, which can extend into the connector hole 12. The snap-fit ​​fastener 2 is used to connect a second rope 200. The snap-fit ​​connector has a locked state and an unlocked state. When the snap-fit ​​connector is in the locked state, the limiting buckle 21 is engaged with the fastening baffle 13 and the fastener 3. Pressing the snap-fit ​​fastener 2 unlocks the snap-fit ​​connector. When the snap-fit ​​connector is in the unlocked state, the limiting buckle 21 disengages from the fastening baffle 13 and the fastener 3. The snap-fit ​​connector enhances its connection strength by double-engaging the limiting buckle 21 with the buckle baffle 13 and the locking element 3, preventing the snap-fit ​​connector from detaching. Furthermore, the pressing mechanism facilitates user operation and improves the user experience. The snap-fit ​​connector also features a simple structure, is easy to assemble, and is low in cost. Specifically, the locking element 3 engages with the inner wall of the mounting groove 11.

[0046] Optionally, a connecting shaft 22 is provided between the limiting buckle 21 and the plug-in fastener 2, with the end of the limiting buckle 21 facing the connecting shaft 22 serving as the abutment surface, so that the limiting buckle 21 can abut against the side of the fastening baffle 13 facing away from the plug-in fastener 2. Specifically, the limiting buckle 21 is elliptical, and the connecting shaft 22 is a cuboid structure. In this embodiment, the connecting shaft 22 and the limiting buckle 21 are integrally formed. In other embodiments, the forming method of the connecting shaft 22 and the limiting buckle 21 can be adapted according to actual needs and is not limited to this embodiment.

[0047] Optionally, two buckle baffles 13 are provided, and the two buckle baffles 13 are respectively provided on two opposite side walls of the insertion hole 12 so that the insertion hole 12 is convex. The insertion hole 12 includes a mounting part 121 and a locking part 122. When the snap-fit ​​connector is in the locked state, the limit buckle 21 is located in the locking part 122; when the snap-fit ​​connector is in the unlocked state, the limit buckle 21 extends out through the mounting part 121.

[0048] Specifically, the width of the locking part 122, i.e., the distance between the two latching baffles 13, is equal to the width of the connecting shaft 22, so that the connecting shaft 22 can extend into the locking part 122 and fit against the two latching baffles 13, preventing the connecting shaft 22 from moving within the locking part 122 and improving the connection stability of the snap-fit ​​connector. The width of the mounting part 121 is set according to specific circumstances so that the limiting buckle 21 can smoothly extend into the mounting part 121. In other embodiments, the limiting buckle 21 may also be a cuboid structure or an oblong structure.

[0049] Optionally, the clip 3 is provided with an assembly hole 31, and a spring piece 32 is provided on the side wall of the assembly hole 31. The spring piece 32 is provided with a limiting protrusion 33. When the snap-fit ​​connector is in the locked state, the limiting buckle 21 abuts against the side of the limiting protrusion 33 near the bottom wall of the mounting groove 11 to achieve the snap-fit ​​between the limiting buckle 21 and the limiting protrusion 33. When the limiting buckle 21 is inserted into the mounting part 121, the limiting buckle 21 is located on the side of the limiting protrusion 33 facing away from the bottom wall of the mounting groove 11. When the limiting buckle 21 is pressed, the limiting buckle 21 will squeeze the limiting protrusion 33, thereby causing the spring piece 32 to elastically deform. The limiting buckle 21 moves to the side near the bottom wall of the mounting groove 11, so that the limiting buckle 21 snaps against the side of the limiting protrusion 33 facing the bottom wall of the mounting groove 11. At this time, the limiting buckle 21 is just located in the locking part 122 and is snapped and fixed with the two buckle baffles 13. Press the limit buckle 21 in the opposite direction to push it to the mounting part 121, thereby removing the limit buckle 21 from the insertion hole 12. Specifically, the material of the clip 3 is plastic or rubber, which makes the clip 3 corrosion resistant and has a long service life.

[0050] Optionally, the limiting protrusion 33 extends axially along the insertion hole 12, increasing the contact area between the limiting protrusion 33 and the limiting buckle 21, thereby improving the engagement strength between the limiting protrusion 33 and the limiting buckle 21. The cross-section of the limiting protrusion 33 is trapezoidal or arc-shaped to facilitate the movement of the limiting buckle 21 and prevent jamming. In this embodiment, the cross-section of the limiting protrusion 33 is trapezoidal.

[0051] Optionally, two springs 32 are provided, with the two springs 32 respectively located on the two opposite side walls of the mounting hole 31, which facilitates pressing the limit buckle 21 and makes it easy for the user to operate.

[0052] Optionally, the end of the clip 3 furthest from the bottom wall of the mounting groove 11 is flush with the outer wall of the connector 1, making the overall structure of the snap-fit ​​connector more aesthetically pleasing. Furthermore, when the rotary connector is in the locked state, the outer wall of the connector 1 and the outer wall of the snap-fit ​​clip 2 are flush, further improving the overall aesthetics of the snap-fit ​​connector.

[0053] Optionally, such as Figure 7 and Figure 8 As shown, in this embodiment, the outer wall of the connector 1 is provided with a first anti-slip protrusion 14, and the outer wall of the connector fastener 2 is provided with a second anti-slip protrusion 23. In other embodiments, the outer wall of the connector 1 is provided with a first anti-slip protrusion 14, or the outer wall of the connector fastener 2 is provided with a second anti-slip protrusion 23, to increase the friction between the user's hand and the connector 1 and the connector fastener 2, making it easier for the user to operate.

[0054] Optionally, in this embodiment, the plug-in base 1 has a first fixing hole 15 for fixing the first rope 100 on the side opposite to the plug-in fastener 2, and the plug-in fastener 2 has a second fixing hole 24 for fixing the second rope 200 on the side opposite to the plug-in base 1. In other embodiments, the plug-in base 1 has a first fixing hole 15 for fixing the rope end on the side opposite to the plug-in fastener 2, or the plug-in fastener 2 has a second fixing hole 24 for fixing the rope end on the side opposite to the plug-in base 1.

[0055] like Figure 9 As shown, this embodiment also provides a hanging rope structure, including a first rope body 100, a second rope body 200 and the above-mentioned snap-fit ​​connecting buckle. The first rope body 100 is arranged to form a wearing ring 101, and the second rope body 200 is used to connect the device. One of the plug-in seat 1 and the plug-in buckle 2 is connected to the first rope body 100 and the other is connected to the second rope body 200.

[0056] Specifically, such as Figures 7-12As shown, the lanyard structure also includes a length adjustment component 300, an anti-lock fastener assembly 400, and a main unit connector 500. The first rope body 100 includes a first rope segment 102, a second rope segment 103, and a third rope segment 104. The first end of the first rope segment 102 and the first end of the third rope segment 104 are both fixedly connected to the first fixing hole 15 of the connector 1. The anti-lock fastener assembly 400 includes a first safety buckle 401 and a second safety buckle 402. The opposite sides of the first safety buckle 401 and the second safety buckle 402 can be snapped together for fixation. Both the opposite sides of the first safety buckle 401 and the second safety buckle 402 are provided with rope end fixing blind holes. The first end of the second rope segment 103 is connected to the rope end fixing blind hole of the first safety buckle 401, and the second end of the third rope segment 104 is connected to the rope end fixing blind hole of the second safety buckle 402. When worn normally, the first rope 100 is arranged in a wearing loop 101. In case of an accident, such as when the first rope 100 cannot be removed from the user's neck or wrist, the anti-lock fastener assembly 400 can unfold the wearing loop 101, thereby successfully removing the first rope 100 from the user's neck or wrist and avoiding safety risks associated with the multi-functional lanyard.

[0057] Specifically, the length adjusting member 300 is provided with a blind hole for fixing the rope end and a first rope threading hole 301. The first rope threading hole 301 extends along the axial direction of the length adjusting member 300 and passes through the length adjusting member 300. There are two length adjusting members 300. The second end of the first rope segment 102 and the second end of the second rope segment 103 correspond to the two length adjusting members 300 respectively and are threaded through the first rope threading hole 301 on the corresponding length adjusting member 300. Both are fixedly connected to the blind hole for fixing the rope end on the other length adjusting member 300. The size of the wearing ring 101 can be adjusted by adjusting the relative position of the length adjusting members 300. When wearing, the user can flexibly adjust the size of the wearing ring 101. The main unit connector 500 is provided with a second rope threading hole 501. The second rope body 200 passes through the second rope threading hole 501, and both ends of the second rope body 200 are fixedly connected to the second fixing hole 24 of the plug-in fastener 2. The main unit connector 500 is used to connect the device.
