Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to an elastic snap-fit ​​connector and a product equipped with the elastic snap-fit ​​connector. Background Technology

[0002] Currently, bolts are commonly used to connect metal parts; however, this method has the following drawbacks:

[0003] First, the connection process is cumbersome and inefficient. Before connection, holes need to be drilled and tapped in the parts to create threads that match the bolt. During connection, the bolt end is placed into the threaded hole and the bolt is turned, allowing it to be screwed into the threaded holes of the two parts sequentially and gradually. The engagement between the external thread of the bolt and the internal thread of the threaded hole achieves the effect of fastening the two parts. Because the bolt needs to be continuously turned until it is gradually screwed into the threaded holes of the two parts during assembly, the assembly time is long and the efficiency is low.

[0004] Secondly, it hinders the secondary assembly and disassembly of parts. Since bolts achieve their fastening connection through the engagement of their external threads with the internal threads of the threaded hole, each assembly and disassembly of the bolt and threaded hole accelerates the wear of the bolt's external threads and / or the internal threads of the threaded hole. When the assembly position of the parts needs adjustment, stripping can easily occur between the bolt and the threaded hole during secondary assembly, thus affecting the stability of the connection between the parts. Furthermore, during assembly, a slight angle between the bolt's axis and the threaded hole's axis can also easily lead to wear of the bolt's external threads and / or the threaded hole's internal threads, further causing stripping between the bolt and the threaded hole.

[0005] Third, it is detrimental to the surface treatment of parts. Usually, parts need to undergo surface treatment, and during surface treatment, threaded holes need to be protected to prevent dust, paint, etc. from entering the threaded holes and making it difficult to assemble bolts into the threaded holes. Protecting the threaded holes increases the number of processing steps, thereby reducing production efficiency. At the same time, protecting the threaded holes also increases the risk of poor surface treatment when performing surface treatment on the parts. Summary of the Invention

[0006] To address the aforementioned problems, the main objective of this utility model is to provide an elastic snap-fit ​​connector that improves assembly efficiency, enables secondary disassembly and assembly between parts, and facilitates surface treatment of the parts.

[0007] Another objective of this invention is to provide a product equipped with the aforementioned elastic snap-fit ​​connector.

[0008] To achieve the main objective of this utility model, it provides an elastic snap-fit ​​connector, comprising a connecting elbow and a first movable arm and a second movable arm arranged opposite to each other. The connecting elbow connects the first end of the first movable arm and the first end of the second movable arm, forcing the first and second movable arms to move in opposite directions. The second end of the first movable arm is bent away from the second movable arm to form a first pressing portion. The first movable arm is provided with an elastic barb that extends obliquely from the first movable arm away from the second movable arm and obliquely toward the first end of the first movable arm, forming a first clamping position between the first pressing portion and the elastic barb. The second end of the second movable arm is bent away from the first movable arm to form a second pressing portion, and the first end of the second movable arm is bent away from the first movable arm to form a support portion, forming a second clamping position between the second pressing portion and the support portion.

[0009] As can be seen from the above, when using the elastic snap-fit ​​connector, it passes through the connection holes of each part to clamp and fix the stacked parts in the first and second clamping positions, thereby achieving a fixed connection of two or more parts. Simultaneously, the first and second movable arms move in opposite directions under the action of the connecting elbow, thus tightly fitting against the inner walls of the connection holes of each part, working in conjunction with the first and second clamping positions to prevent detachment. By using the elastic snap-fit ​​connector to fix the parts, the tapping process required when using bolts to fix the parts is effectively eliminated, and assembly efficiency is also significantly improved. Furthermore, the masking process required for the connection holes during surface treatment of the parts is eliminated, reducing production costs and further improving production efficiency. Moreover, using the elastic snap-fit ​​connector to connect the parts avoids damage to the connector itself or other parts during disassembly and assembly, allowing for secondary disassembly and assembly between the parts and the elastic snap-fit ​​connector, thus facilitating the maintenance of products equipped with this elastic snap-fit ​​connector.

[0010] A preferred embodiment is that there is a first clamping distance between the first pressing part and the elastic barb part, and a second clamping distance between the second pressing part and the support part; the first clamping distance and the second clamping distance are equal, or the first clamping distance and the second clamping distance are not equal.

[0011] As can be seen from the above, this design makes the elastic snap-fit ​​connector suitable for different assembly structures, improving the practicality and applicability of the elastic snap-fit ​​connector.

[0012] Another preferred embodiment is that the end face of the protruding end of the elastic barb is a first support plane; the support portion has a second support plane.

[0013] As can be seen from the above, the design of the first support surface enables the elastic barbs to reliably support the clamped parts, thereby cooperating with the first pressing part to reliably clamp and fix each part. At the same time, the first support surface can reduce the pressure generated by the elastic barbs on the parts, thereby preventing the parts from being squeezed and damaged. Similarly, the second support surface enables the support part to reliably support the clamped parts, thereby cooperating with the second pressing part to reliably clamp and fix each part. The second support surface can also reduce the pressure generated by the support part on the parts, thereby preventing the parts from being squeezed and damaged.

[0014] Another preferred embodiment is that the elastic barb portion and the first movable arm have a first included angle, the first included angle being between 18° and 30°.

[0015] As can be seen from the above, this design ensures that the elastic barb and the first pressing part cooperate to form effective support for each part and ensure the clamping and fixing effect of each part; at the same time, it also makes the elastic barb have sufficient elastic deformation capacity and facilitates the disassembly of the elastic buckle connector.

[0016] Another preferred embodiment is that the first bending length of the first pressing part is less than the second bending length of the second pressing part.

[0017] As can be seen from the above, in some installation environments, the spaces on both sides of the connection hole may be of different sizes, and when the elastic snap fastener is disassembled, the elastic barb needs to be pressed appropriately to disengage the elastic barb from the fastening connection with the part. Therefore, considering most installation environment conditions, the above design enables the elastic snap fastener to be reliably assembled with each component, and makes the disassembly of the elastic snap fastener more convenient and easier to operate.

[0018] A further embodiment is that the first pressing part and the first movable arm have a second included angle, the second included angle being between 90° and 160°; the second pressing part and the second movable arm have a third included angle, the third included angle being between 90° and 100°.

[0019] As can be seen from the above, the design of the first pressing part ensures that the first pressing part and the elastic barb part can reliably clamp and fix each part, while minimizing space constraints. This ensures that the elastic snap fastener can be assembled with each part, and also makes it easy to move the first pressing part to separate the first movable arm from the inner wall of the connection hole of the part. The design of the second pressing part ensures that the second pressing part and the support part can reliably clamp and fix each part, and also makes it easy to move the second pressing part to separate the second movable arm from the inner wall of the connection hole of the part.

[0020] Another preferred option is that the connecting elbow is arc-shaped or V-shaped.

[0021] As can be seen from the above, the design makes the connecting elbow have good elasticity, so as to ensure that the first movable arm and the second movable arm open in opposite directions and move toward the inner wall of the connecting hole of each part, thereby ensuring that the first clamping position and the second clamping position reliably clamp and fix each part, and effectively prevent the elastic buckle connector from coming out of the connecting hole of each part.

[0022] A further option is that the elastic snap-fit ​​connector is formed from stainless steel through a stamping process; or the elastic snap-fit ​​connector is formed through an injection molding process.

[0023] As can be seen from the above, the design gives the elastic snap-fit ​​connector excellent structural strength and excellent elastic deformation capability, ensuring the reliability of the elastic snap-fit ​​connector in clamping and fixing various parts, while also guaranteeing the service life of the elastic snap-fit ​​connector, and making the production of the elastic snap-fit ​​connector more convenient.

[0024] To achieve another objective of this utility model, this utility model provides a product comprising a first part and a second part. The first part has a first connecting hole, and the second part has a second connecting hole. The product further includes the aforementioned elastic snap fastener, which is inserted into the first and second connecting holes. The first part and the second part are clamped and fixed within the first and second clamping positions.

[0025] As can be seen from the above, by using the aforementioned elastic snap-fit ​​connectors to fix and connect the various parts, the product can effectively improve the assembly efficiency, reduce production costs, simplify the production process, and also make the product maintainable and easier to maintain.

[0026] A further option is for the products to be lighting fixtures, home appliances, or vehicles.

[0027] As can be seen from the above, the elastic snap fastener can be used for different types of products and has the advantages of wide applicability and strong practicality. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0034] Example of a flexible snap-fit ​​connector

[0035] Reference Figure 1 and Figure 2 The elastic snap fastener 100 includes a first movable arm 1, a second movable arm 2, and a connecting elbow 3; wherein the first movable arm 1 and the second movable arm 2 are arranged opposite to each other, and the connecting elbow 3 is connected between the first end of the first movable arm 1 and the first end of the second movable arm 2. The connecting elbow 3 is used to force the first movable arm 1 and the second movable arm 2 to move in opposite directions, so that the connecting elbow 3 can make the first movable arm 1 and the second movable arm 2 tightly fit on the inner wall of the connecting hole of the part.

[0036] The second end of the first movable arm 1 has a first pressing portion 11, which is bent away from the second movable arm 2. The first movable arm 1 has an elastic barb portion 12, which extends obliquely from the first movable arm 1 away from the second movable arm 2 and also extends obliquely toward the first end of the first movable arm 1, so that the elastic barb portion 12 can elastically deform relative to the first movable arm 1. A first clamping position 10 is formed between the first pressing portion 11 and the elastic barb portion 12.

[0037] The second end of the second movable arm 2 has a second pressing part 21, which is bent in the opposite direction to the first movable arm 1; the first end of the second movable arm 2 also has a support part 22, which is bent in the opposite direction to the first movable arm 1. A second clamping position 20 is formed between the second pressing part 21 and the support part 22.

[0038] like Figure 3As shown, when using the elastic snap fastener 100 to fix two or more parts together (this embodiment uses two parts as an example, but this does not limit the use of the elastic snap fastener 100; that is, the elastic snap fastener 100 can also fix three, four, five or more stacked parts together), the elastic snap fastener 100 is passed through the first connecting hole 1011 of the first part 101 and the second connecting hole 1021 of the second part 102 in sequence, so that the first part 101 and the second part 102 after the first stack are clamped and fixed in the first clamping position 10 and the second clamping position 20, thereby realizing the fixed connection of the first part 101 and the second part 102. Furthermore, due to the action of the connecting elbow 3, the first movable arm 1 and the second movable arm 2 move in opposite directions, thereby causing the first movable arm 1 and the second movable arm 2 to fit tightly against the inner wall of the first connecting hole 1011 and the inner wall of the second connecting hole 1021; at the same time, the engagement and clamping of the first part 101, the second part 102 and the first clamping position 10, and the engagement and clamping of the first part 101, the second part 102 and the second clamping position 20 can effectively prevent the elastic buckle connector 100 from disengaging from the first part 101 and the second part 102.

[0039] Furthermore, using the elastic snap-fit ​​connector 100 to fix the first part 101 and the second part 102 effectively eliminates the need for tapping when using bolts to fix the first part 101 and the second part 102, thus improving assembly efficiency. It also eliminates the need for masking spraying of the first connecting hole 1011 and the second connecting hole 1021 during surface treatment, reducing production costs and further improving production efficiency. In addition, connecting the first part 101 and the second part 102 with the elastic snap-fit ​​connector 100 avoids damage to the connector itself, the first part 101, and the second part 102 during assembly and disassembly, allowing for multiple assembly and disassembly of the first part 101, the second part 102, and the elastic snap-fit ​​connector 100, thereby facilitating maintenance of products equipped with this elastic snap-fit ​​connector 100. In this design, the elastic barb 12 can be elastically deformed, and the elastic buckle connector 100 as a whole is elastically deformed through the first movable arm 1, the second movable arm 2, and the connecting elbow 3, making the installation of the elastic buckle connector 100 more convenient and labor-saving. Moreover, the elastically deformable barb 12 generates an upward pushing force relative to the first pressing part 11, while the first pressing part 11 generates a downward pressure relative to the elastic barb 12. This allows the cooperation between the elastic barb 12 and the first pressing part 11 to clamp the first part 101 and the second part 102 more firmly and reliably, and the elastic barb 12 also has a certain degree of anti-disassembly effect.

[0040] It should be noted that the aforementioned anti-disassembly effect refers to the fact that when disassembling the elastic snap connector 100, pressing the elastic barb 12 with a tool to disengage it from the engagement with the second part 102 is more convenient than pressing the elastic barb 12 by hand. In other words, the elastic snap connector 100 can be further configured to require the assistance of a tool for disassembly, thereby better preventing users from disassembling the elastic snap connector 100 and improving its anti-disassembly effect. Furthermore, the anti-disassembly effect can be further enhanced by positioning the elastic barb 12 of the assembled elastic snap connector 100 inside the part, increasing the difficulty of disassembly for the user. Therefore, the aforementioned anti-disassembly is not non-removable; furthermore, increasing the difficulty of disassembly for users does not mean that the elastic snap fastener 100 is difficult to disassemble or that the product equipped with the elastic snap fastener 100 is difficult to maintain. Rather, it means that the means of disassembling the elastic snap fastener 100 can usually be aided by tools to make it easier for the elastic barb 12 to disengage from the engagement with the second part 102. Therefore, the foregoing content is not contradictory.

[0041] A first clamping distance W1 exists between the first pressing part 11 and the elastic barb part 12, which is also the clamping thickness of the first clamping position 10; a second clamping distance W2 exists between the second pressing part 21 and the support part 22, which is also the clamping thickness of the second clamping position 20. In one optional configuration, the first clamping distance W1 and the second clamping distance W2 are equal; in another optional configuration, the first clamping distance W1 may not be equal to the second clamping distance W2. This design allows the elastic snap-fit ​​connector 100 to be applicable to different assembly structures (e.g., the peripheral structures of the first connecting hole 1011 and the second connecting hole 1021 are both flat, or the peripheral structures of the first connecting hole 1011 and the second connecting hole 1021 are both stepped), improving the practicality and applicability of the elastic snap-fit ​​connector 100.

[0042] Preferably, the end face of the protruding end of the elastic barb 12 is designated as the first support plane 121, so that the protruding end of the elastic barb 12 can reliably support the second part 102 and cooperate with the first pressing part 11 to reliably clamp and fix each part; in addition, the first support plane 121 can reduce the pressure generated by the elastic barb 12 on the second part 102, thereby preventing the second part 102 from being squeezed and damaged. Similarly, the support part 22 is provided with a second support plane 221, which can reduce the pressure generated by the support part 22 on the second part 102, thereby preventing the second part 102 from being squeezed and damaged. Furthermore, the support part 22 can reliably support the second part 102 through the second support plane 221, so as to cooperate with the second pressing part to reliably clamp and fix each part.

[0043] Furthermore, since the elastic barb 12 is inclined to the first movable arm 1, there is a first included angle α between the elastic barb 12 and the first movable arm 1, wherein the first included angle α is preferably between 18° and 30°. This design ensures that the elastic barb 12 has sufficient elastic deformation capacity to facilitate the installation and removal of the elastic snap fastener 100; it also ensures that the protruding end of the elastic barb 12 can provide sufficiently stable and reliable support for the second part 102, thereby effectively and reliably clamping and fixing the parts together with the first pressing part 11.

[0044] Furthermore, the first bending length L1 of the first pressing part 11 can be made smaller than the second bending length L2 of the second pressing part 21. Since in some installation environments, the spaces on both sides of the connecting hole may be of different sizes, and when disassembling the elastic snap fastener 100, the elastic barb 12 needs to be appropriately pressed to disengage from the fastening connection with the part, therefore, considering most installation environment conditions [such as...], Figure 3 As shown, a first sidewall 1012 may exist on the first side of the first connecting hole 1011, and a second sidewall 1022 may exist at the second connecting hole 1021. The first sidewall 1012 and the second sidewall 1022 are located on opposite sides of the first connecting hole 1011 and the second connecting hole 1021, respectively. In order to facilitate operation and pressing the elastic barb 12 for deformation, the elastic barb 12 will be provided on the first side of the second connecting hole 1021 (i.e., the side away from the second sidewall 1022 at the second connecting hole 1021). Therefore, the first pressing part 11 will be close to the first sidewall 1012 at the first connecting hole 1011. By designing the first bending length L1 of the first pressing part 11 and the second bending length L2 of the second pressing part 21, it is possible to make the disassembly of the elastic buckle connector 100 more convenient and easier to operate while ensuring that the elastic buckle connector 100 reliably fixes the various components.

[0045] Since the first pressing part 11 and the first movable arm 1 are bent, there is a second included angle b between the first pressing part 11 and the first movable arm 1. The second included angle b is preferably between 90° and 160°; more preferably, the second included angle b is greater than 120°. By designing the second included angle b, under the premise of ensuring that the first pressing part 11 and the elastic barb part 12 cooperate to reliably clamp and fix each part, the bending length design of the first pressing part 11 minimizes the space restriction of the first pressing part 11, so as to ensure that the elastic buckle connector 100 can be assembled with each part; at the same time, it is also convenient to move the first pressing part 11 to separate the inner wall of the connection hole of the first movable arm 1 from that of each part.

[0046] Because the second pressing part 21 and the second movable arm 2 are bent, there is a third included angle c between the second pressing part 21 and the second movable arm 2. The third included angle c is preferably between 90° and 100°; more preferably, the third included angle c is greater than 95°. By designing the third included angle c, while ensuring that the second pressing part 21 and the support part 22 reliably clamp and fix each part, it is easy to move the second pressing part 21 so that the second movable arm 2 can be separated from the inner wall of the connection hole of each part.

[0047] In this embodiment, the connecting elbow 3 is arc-shaped; this design gives the connecting elbow 3 good elasticity, ensuring that the first movable arm 1 and the second movable arm 2 open in opposite directions and move toward the inner wall of the connecting hole of each part, thereby ensuring that the first clamping position 10 and the second clamping position 20 reliably clamp and fix each part, and effectively preventing the elastic snap-fit ​​connector 100 from coming out of the connecting hole of each part. Of course, as another optional solution, in other embodiments, the connecting elbow 3 can also be designed to be V-shaped.

[0048] Furthermore, the elastic snap-fit ​​connector 100 is preferably formed from stainless steel using a stamping process. The elastic barb 12 is also formed using a stamping process. During forming, a portion of the elastic barb 12 is stamped and cut away from the first movable arm 1, while the other portion remains connected to the first movable arm 1 (i.e., the fixed end of the elastic barb 12 is connected to the first movable arm 1). Therefore, the first movable arm 1 will have a cavity 13 due to the peeling off of the elastic barb 12. This design gives the elastic snap-fit ​​connector 100 excellent structural strength and excellent elastic deformation capability, ensuring the reliability of the elastic snap-fit ​​connector 100 in clamping and fixing various parts, while also guaranteeing the service life of the elastic snap-fit ​​connector 100, and making the production of the elastic snap-fit ​​connector 100 more convenient. Of course, as another optional solution, in other embodiments, the elastic snap-fit ​​connector 100 can also be formed using an injection molding process.

[0049] In summary, using the elastic snap-fit ​​connector 100 to connect two or more parts can improve assembly efficiency, allow for secondary disassembly and assembly between parts, facilitate the maintenance of products equipped with the elastic snap-fit ​​connector 100, and also benefit the surface treatment of parts, simplify production processes, reduce production costs, and improve production efficiency.

[0052] The product (such as a lamp) includes a first part 101 (such as a heat sink), a second part 102 (such as a lamp body), and the elastic snap-fit ​​connector 100 described in the above embodiment. The first part 101 has a first connecting hole 1011, and the second part 102 has a second connecting hole 1021.
