Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, in particular to a novel cover buckle structure for fixing and protecting a PIN pin of an electronic device. Background Art

[0002] With the rapid development of electronic technology, electronic products are becoming increasingly sophisticated, placing higher demands on the connection methods of electronic components. PIN pins, a common connection element, are widely used in circuit boards, connectors, and other devices to transmit and connect electronic signals. However, due to their small size and delicate operating environments, securing and protecting PIN pins presents a technical challenge.

[0003] In order to ensure the stability and reliability of the PIN during use, a special cover buckle structure is needed to protect and fix these PINs. There are many different fixing methods available, but there are some common problems, such as loose fixation, easy to fall off or damage to the PIN.

[0004] like Figure 1 As shown, the existing cover buckle structure mainly includes a support part 1 and a plurality of elastic arms 2. The elastic arms 2 are provided at the edge of the support part 1 and are distributed along the circumference. A buckle part 3 is provided on each elastic arm 2 for interfering with the PIN pin and achieving fixation. Although this cover buckle structure solves the problem of fixing the PIN pin to a certain extent, some shortcomings have been found in actual applications. The edge of the support part and the cross-section of the elastic arm of the cover buckle are generally designed to be arc-shaped. Although this design is visually beautiful, it has obvious defects in mechanical properties; when the cover buckle contacts the PIN pin, due to the arc design of the elastic arm and the support part, stress will be concentrated at the junction of the elastic arm and the support part. This stress concentration phenomenon can easily lead to material fatigue, thereby increasing the risk of the cover buckle breaking and affecting the stability and service life of the entire cover buckle structure.

[0005] In view of the stress concentration and fracture problems that occur in the existing cover buckle structure in practical applications, it is necessary to improve the design of the cover buckle structure to improve its mechanical properties and reliability. Utility Model Content

[0006] The main purpose of the utility model is to provide a new cover buckle structure for fixing and protecting PIN pins of electronic equipment with good mechanical properties and good reliability.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: a new cover buckle structure for fixing and protecting the PIN pin of an electronic device, comprising

[0008] a polygonal support portion;

[0009] a plurality of planar elastic arms, the elastic arms being arranged at the edge of the support portion and being distributed symmetrically about the center;

[0010] The elastic arm is provided with a buckling portion, and the buckling portion is used to abut against the side wall of the PIN needle.

[0011] Furthermore, the elastic arm and the support portion are an integrally formed one-piece structure.

[0012] Furthermore, the thickness of the elastic arm is 0.5 mm to 2 mm.

[0013] Furthermore, it also includes an elastic limiting ring, and the outer side wall of each elastic arm is in conflict with the inner side wall of the elastic limiting ring.

[0014] Furthermore, the elastic limiting ring is made of rubber, silicone or thermoplastic elastomer.

[0015] Furthermore, an elastic buffer is provided on the support portion, and the elastic buffer contacts an end of the PIN needle close to the support portion.

[0016] Furthermore, the elastic buffer is adhesively connected to the support portion.

[0017] Furthermore, the elastic buffer is made of rubber, silicone, sponge or thermoplastic elastomer.

[0018] Furthermore, the elastic buffer is a buffer arm provided at the edge of the support portion, and the buffer arm and the support portion are an integrally formed one-piece structure.

[0019] Furthermore, the buffer arm is located between two adjacent elastic arms.

[0020] The beneficial effects of the present invention are as follows: the new cover buckle structure for fixing and protecting the PIN pin of electronic equipment provided by the present invention has the characteristics of good mechanical properties and good reliability. The support part adopts a polygonal design, and the elastic arm is planar, so the stress distribution is more uniform when in contact with the PIN pin. Compared with the traditional arc-shaped elastic arm, the planar design provides a larger contact area and more uniform stress distribution, reduces stress concentration points, and thus reduces the risk of breakage; the elastic arms are distributed centrally and symmetrically on the support part, ensuring that each elastic arm is evenly stressed, thereby improving the stability of the overall structure.

[0036] The elastic arm 2 is provided with a buckling portion 3, and the buckling portion 3 is used to abut against the side wall of the PIN needle.

[0037] From the above description, it can be seen that the beneficial effect of the present invention is that the support part 1 adopts a polygonal design, and the elastic arm 2 is planar, so the stress distribution is more uniform when in contact with the PIN needle. Compared with the traditional arc-shaped elastic arm 2, the planar design provides a larger contact area and a more uniform stress distribution, reduces stress concentration points, and thus reduces the risk of fracture; the elastic arms 2 are distributed centrally and symmetrically on the support part 1, ensuring that each elastic arm 2 is evenly stressed and improving the stability of the overall structure.

[0038] Furthermore, the elastic arm 2 and the support portion 1 are an integrally formed one-piece structure.

[0039] As can be seen from the above description, the integral molding of the elastic arm 2 and the support portion 1 reduces the number of assembly steps, improves production efficiency, and enhances the stability and durability of the overall structure due to the reduction in joining points.

[0040] Furthermore, the thickness of the elastic arm 2 is 0.5 mm to 2 mm.

[0041] As can be seen from the above description, the thickness range of 0.5 mm to 2 mm provides the elastic arm 2 with sufficient elasticity and strength to accommodate PINs of different diameters, while ensuring the durability of the elastic arm 2 .

[0042] Furthermore, an elastic limiting ring is included, and the outer side wall of each elastic arm 2 is in conflict with the inner side wall of the elastic limiting ring.

[0043] As can be seen from the above description, an elastic limiting ring is provided on the outer side of each elastic arm 2 to limit excessive deformation of the elastic arm 2 and prevent structural damage caused by excessive extension of the elastic arm 2.

[0044] Furthermore, the elastic limiting ring is made of rubber, silicone or thermoplastic elastomer.

[0045] As can be seen from the above description, the elastic limiting ring made of rubber, silicone or thermoplastic elastomer has good elasticity and wear resistance, can adapt to different usage environments, and provide a lasting limiting effect.

[0046] Furthermore, an elastic buffer 4 is provided on the support portion 1 , and the elastic buffer 4 contacts an end of the PIN needle close to the support portion 1 .

[0047] As can be seen from the above description, the elastic buffer member 4 provided on the support portion 1 provides additional protection for the PIN pin, and reduces direct impact on the PIN pin by buffering the contact force.

[0048] Furthermore, the elastic buffer member 4 is adhesively connected to the support portion 1 .

[0049] As can be seen from the above description, the elastic buffer 4 is connected to the support portion 1 by gluing, which simplifies the assembly process and ensures a firm connection between the buffer and the support portion 1.

[0050] Furthermore, the elastic buffer member 4 is made of rubber, silicone, sponge or thermoplastic elastomer.

[0051] As can be seen from the above description, the buffer member made of rubber, silicone, sponge or thermoplastic elastomer provides good elasticity and cushioning effect, adapts to impacts of different strengths, and protects the PIN needle.

[0052] Furthermore, the elastic buffer member 4 is a buffer arm provided at the edge of the support portion 1 , and the buffer arm and the support portion 1 are an integrally formed one-piece structure.

[0053] As can be seen from the above description, the buffer arm serves as an elastic buffer member 4 and is integrally formed with the support portion 1 , thereby enhancing the integrity and aesthetics of the structure while ensuring the consistency of the buffer effect.

[0054] Furthermore, the buffer arm is located between two adjacent elastic arms 2 .

[0055] As can be seen from the above description, the buffer arm is located between two adjacent elastic arms 2 . This layout helps to evenly distribute the force from the PIN needle and reduces the local pressure on the support part 1 or the elastic arm 2 .

Compared with the traditional arc-shaped elastic arm 2, the planar design provides a larger contact area and a more uniform stress distribution, reduces stress concentration points, and thus reduces the risk of breakage; the elastic arms 2 are distributed symmetrically in the center of the support portion 1, ensuring that each elastic arm 2 is evenly stressed and improving the stability of the overall structure; specifically, the elastic arm 2 and the support portion 1 are an integrally formed one-piece structure, which reduces the assembly steps and improves production efficiency, and because the number of joints is reduced, the stability and durability of the overall structure are enhanced.

[0058] Optionally, the thickness of the elastic arm 2 is 0.5 mm to 2 mm; specifically, the thickness range of 0.5 mm to 2 mm provides the elastic arm 2 with sufficient elasticity and strength to adapt to PIN pins of different diameters, while ensuring the durability of the elastic arm 2; further optionally, an elastic limiting ring may be provided, and the outer side wall of each elastic arm 2 is in conflict with the inner side wall of the elastic limiting ring.

[0059] Example 2

[0060] Please refer to Figure 3, Example 2 of the present invention is a further improvement on the basis of Example 1. The difference between Example 2 and Example 1 is that: an elastic buffer 4 is further provided on the support portion 1, and the elastic buffer 4 is in contact with the end of the PIN needle close to the support portion 1. The elastic buffer 4 provided on the support portion 1 provides additional protection for the PIN needle, and reduces the direct impact on the PIN needle by buffering the contact force; specifically, in this embodiment, the elastic buffer 4 is adhesively connected to the support portion 1, and the elastic buffer 4 is connected to the support portion 1 by adhesive, which simplifies the assembly process and ensures a firm connection between the buffer and the support portion 1; optionally, the elastic buffer 4 is made of rubber, silicone, sponge or thermoplastic elastomer. It is easy to understand that the buffer made of rubber, silicone, sponge or thermoplastic elastomer provides good elasticity and buffering effect, adapts to impacts of different forces, and protects the PIN needle.

[0061] In addition, in some other embodiments, the elastic buffer 4 can also be a buffer arm provided at the edge of the support portion 1, and the buffer arm and the support portion 1 are an integral structure formed as one piece; it can be understood that the buffer arm, as an elastic buffer 4, is integrally formed with the support portion 1, which enhances the integrity and aesthetics of the structure while ensuring the consistency of the buffering effect; further, the buffer arm is located between two adjacent elastic arms 2, and the buffer arm is located between two adjacent elastic arms 2.
