Description

Technical Field

[0001] This utility model relates to the field of electronic component packaging materials technology, specifically a sealing pin for electronic component tube packaging and drop-resistant electronic component tube packaging. Background Technology

[0002] Plastic tubular packaging (tube packaging) for electronic components with leads, such as Figure 1 As shown, the tube packaging has openings at both ends; the tube 3 of the tube packaging includes an upper surface, a lower surface, and two side surfaces. The lower surface of the tube has a concave portion 33 in the middle, which causes the two sides to bulge outward to form protective bosses for the leads of electronic components. The protective bosses have recessed accommodating cavities to accommodate the leads of electronic components 4. The height of the highest point of the concave surface of the concave portion 33 from the upper surface matches the height of the electronic components 4.

[0003] In existing technology, both ends of the tube 3 are usually sealed with plugs, which encapsulate the finished electronic components 4 inside the tube 3 for easy packing and transportation. However, plug sealing has problems such as inconvenience for automated loading and unloading; and the rubber material is prone to plastic deformation during long-term extrusion, affecting its service life. Therefore, the original plug sealing is improved to pin sealing.

[0004] Pin insertion holes 31 are formed in the recessed portions 33 on the upper and lower surfaces of both ends of the tube 3. The pins are embedded in the pin insertion holes 31 of the tube 3 to block the electronic components 4. Compared with plugs, this simplifies the tube sealing process, improves automation adaptability, reduces costs, and increases production efficiency.

[0005] However, in practical applications, the aforementioned tube packaging has poor drop resistance. Furthermore, after the electronic component 4 is loaded into the tube 3, multiple tubes 3 are stacked together in a box (outer packaging), typically a cardboard box. When the tube 3 containing the electronic component 4 is dropped inside the packaging box, the weight of the electronic component 4 generates a significant impact inertial force. This force acts on the pin, causing the pin insertion hole 31 near the electronic component 4 to deform and warp. This deformation prevents the component from sliding out smoothly during subsequent automated assembly, causing jamming and severely impacting the customer's production efficiency. Summary of the Invention

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a sealing pin for electronic component tube packaging that is simple in structure, effectively enhances the impact resistance of the pin insertion hole area, and prevents deformation and damage to the pin insertion hole. This also provides drop-resistant electronic component tube packaging.

[0007] The technical objective of this utility model is achieved through the following technical solution: A sealing pin for packaging electronic component tubes includes a pin body for embedding into a pin insertion hole in the tube to block the electronic component; the head of the pin body is formed with a support structure extending axially along the tube, the support structure including an axial connecting section connected to the head of the pin body and a load-bearing portion connected to one end of the axial connecting section; the load-bearing portion is used for embedding into a load-bearing insertion hole in the tube, or is disposed on the outside of the tube end to cooperate with external packaging.

[0008] Preferably, the head of the bearing part is provided with a stop section at the insertion end away from the bearing part, the length of which is less than the depth of the concave portion of the tube; the tail of the pin body extends out of the tube, and the exposed portion of the tail of the pin body is less than the depth of the concave portion; when two tubes are stacked together and axially slide relative to each other under external force, the stop section of one tube and the exposed portion of the other tube form an interlocking engagement.

[0009] Preferably, the thickness of the axial connecting section and the load-bearing part is 2.2~2.8mm.

[0010] Preferably, the outer wall of the pin body is symmetrically provided with anti-disengagement buckles, and at least part of the pin body and the pin insertion hole are in clearance fit; the outer side of the anti-disengagement buckle is provided with an arc-shaped guide slope; when the pin body is inserted into the pin insertion hole, the anti-disengagement buckle can be engaged in the inner recess of the tube and form a locking limit with the inner wall of the inner recess to prevent the pin body from coming out of the pin insertion hole.

[0011] Preferably, the side of the pin body facing the electronic components is a first plane; the surface of the load-bearing part used to cooperate with the outer packaging is a load-bearing surface; the load-bearing surface is a second plane; the first plane and the second plane are parallel to each other.

[0012] Preferably, the surface of the pin body facing away from the electronic component is a first arc surface; the pin insertion hole of the tube has a second arc surface on the side away from the electronic component; the curvature of the first arc surface and the second arc surface are adapted to each other, so that when the pin body is inserted into the pin insertion hole, the first arc surface and the second arc surface form surface contact.

[0013] A drop-resistant tube packaging for electronic components includes a tube with a recessed portion and the aforementioned sealing pins; pin insertion holes are respectively provided at both ends of the tube, and correspondingly, there are two sealing pins; the distance from the pin insertion hole to the adjacent outer wall end face is less than the length of the axial connecting section of the sealing pin, and the distance from the pin body to the load-bearing portion is slightly greater than the distance from the pin insertion hole to the outer wall end face; the load-bearing portion is located on the outer side of the tube end to cooperate with the outer packaging.

[0014] A drop-resistant electronic component tube package includes a tube with a concave portion and the aforementioned sealing pins; each end of the tube has a pin insertion hole, and the concave portion at one end has a load-bearing insertion hole; correspondingly, there are two sealing pins; the pin body of the sealing pin is embedded in the pin insertion hole; the load-bearing portion of the sealing pin at one end of the tube is embedded in the load-bearing insertion hole; the load-bearing portion of the sealing pin at the other end of the tube is disposed on the outer side of the tube end to cooperate with the outer packaging.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The sealing pin of this utility model, through a formed support structure, disperses the axial impact force applied to the pin body to the main body of the tube or the external packaging, thereby effectively preventing deformation and damage to the pin insertion hole of the tube due to stress concentration. This technical measure has the advantages of simple structure, effectively enhancing the impact resistance of the pin insertion hole area, and preventing deformation and damage to the pin insertion hole.

[0016] 2. The interlocking structure of the stop section of the load-bearing part and the exposed section of the pin body of this utility model can effectively limit the axial displacement of the tubes when they are stacked, prevent axial relative sliding and misalignment impact during transportation, and significantly improve the stability of the packaging and the protection of the internal electronic components.

[0017] 3. In this invention, the pin body facing the electronic components has a first plane; the surface of the load-bearing part used to cooperate with the outer packaging is a load-bearing surface; the load-bearing surface is a second plane; the first plane and the second plane are parallel to each other. This parallel plane structure ensures that the impact force can be evenly transmitted to the load-bearing part, thereby significantly improving the efficiency and stability of force transmission, and more effectively preventing deformation of the tube end due to uneven force; furthermore, by optimizing the load distribution of the overall structure, it fundamentally enhances the impact resistance of the tube packaging.

[0018] 4. The pin body of this invention has a first arc surface on the side facing away from the electronic component; the pin insertion hole of the tube has a second arc surface on the side away from the electronic component; the curvatures of the first and second arc surfaces are matched so that when the pin body is inserted into the pin insertion hole, the first and second arc surfaces form surface contact. This wide-area surface contact formed by the matching of the first and second arc surfaces achieves uniform distribution of impact loads, effectively avoids stress concentration, and significantly enhances the tube end's resistance to breakage and plastic deformation; this technical measure further improves the impact resistance of the tube packaging.

[0019] 5. The present invention provides a drop-resistant electronic component tube packaging, comprising a tube with a concave portion and the aforementioned sealing pin; pin insertion holes are respectively provided at both ends of the tube, and correspondingly, there are two sealing pins; the distance from the pin insertion hole to the adjacent outer wall end face is less than the length of the axial connecting section of the sealing pin, and the distance from the pin body to the load-bearing part is slightly greater than the distance from the pin insertion hole to the outer wall end face; the load-bearing part is located on the outer side of the tube end to cooperate with the outer packaging. By setting the "distance from the pin body to the load-bearing part" to be slightly greater than the "distance from the pin insertion hole to the outer wall end face", and by setting the load-bearing part on the outer side of the tube end, when the tube packaging is subjected to a drop impact, the impact force will act directly on the outer packaging through the load-bearing part. This technical measure avoids the impact force from acting directly on the fragile end opening of the tube or the internal electronic components, thereby greatly improving the overall drop resistance.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Example 1 like Figure 1 — Figure 7As shown, a sealing pin for packaging electronic component tubes includes a pin body 1, which is used to insert into a pin insertion hole 31 of a tube 3 to block the electronic component 4; the head of the pin body 1 is formed with a support structure 2 extending axially along the tube 3, the support structure 2 includes an axial connecting section 21 connected to the head of the pin body 1 and a load-bearing part 22 connected to one end of the axial connecting section 21; the load-bearing part 22 is used to be inserted into the load-bearing insertion hole 32 of the tube 3, or is provided on the outside of the end of the tube 3 to cooperate with the outer packaging.

[0026] The sealing pin, through the formed support structure 2, disperses the axial impact force applied to the pin body 1 to the main body of the tube 3 or the external packaging, thereby effectively preventing deformation and damage to the pin insertion hole 31 of the tube 3 due to stress concentration. This technical measure has the advantages of simple structure, effectively enhancing the impact resistance of the pin insertion hole 31 area, and preventing deformation and damage to the pin insertion hole 31.

[0027] like Figures 2-7 As shown, in this embodiment, the tube 3 is a rectangular cylindrical structure, with its length axial. The pin body 1 is a long column, and its overall length is greater than the distance between the highest point of the concave surface of the concave portion 33 and the upper surface. The axial connecting section 21 is a rectangular column structure. The load-bearing part 22 is a rectangular block structure.

[0028] In practical implementation, the thickness of the axial connection section 21 and the load-bearing part 22 is 2.2~2.8mm. This thickness range of 2.2~2.8mm ensures that the support structure 2 has sufficient rigidity to effectively transmit impact force, while avoiding material waste and cost increases caused by excessive redundancy design, thus achieving an optimal balance between structural strength and economy.

[0029] like Figure 2-7 As shown, the head of the bearing part 22, away from the insertion section 221, has a stop section 223 with a length less than the depth of the recess 33 of the tube 3; the tail 11 of the pin body 1 extends out of the tube 3, and the exposed section 111 of the tail 11 is less than the depth of the recess 33; when two tubes 3 are stacked together and axially slide relative to each other under external force, the stop section 223 of one tube and the exposed section 111 of the other tube form an interlocking engagement. This technical measure effectively limits the axial displacement of the tubes 3 when they are stacked, preventing axial relative sliding and misalignment impacts during transportation, significantly improving packaging stability and protection of internal electronic components.

[0030] In specific implementation, anti-disengagement buckles 12 are symmetrically provided on the outer wall of the pin body 1, and at least part of the pin body 1 and the pin insertion hole 31 are in clearance fit; the outer side of the anti-disengagement buckle 12 is provided with an arc-shaped guide slope 121; when the pin body 1 is inserted into the pin insertion hole 31, the anti-disengagement buckle 12 can be locked into the inner recess 33 of the tube 3, and form a locking limit with the inner wall of the inner recess 33 to prevent the pin body 1 from coming out of the pin insertion hole 31. In specific implementation, the tube 3 can be made of transparent plastic. Through the cooperation of the arc-shaped guide slope 121 with the tube 3, the anti-disengagement buckle 12 can be smoothly embedded and accurately locked into the inner wall of the inner recess 33, ensuring that the pin is firmly prevented from falling out. When the packaging is subjected to a drop impact, the locking limit formed by the anti-disengagement buckle 12 and the inner wall of the inner recess 33 constitutes a reliable mechanical interlock. This structure can effectively resist impact inertial force, prevent the pin body 1 from coming loose from the pin insertion hole 31, and ensure the integrity of the impact force transmission path.

[0031] like Figure 5 , Figure 6 As shown, the side of the pin body 1 facing the electronic component 4 is the first plane 13; the surface of the load-bearing part 22 used to cooperate with the outer packaging is the load-bearing surface 222; the load-bearing surface 222 of the load-bearing part 22 is the second plane; the first plane 13 and the second plane are parallel to each other. In specific implementation, this parallel plane structure ensures that the impact force can be evenly transmitted to the load-bearing part 22, thereby significantly improving the efficiency and stability of force transmission, and more effectively preventing deformation of the end of the tube 3 due to uneven force.

[0032] like Figure 5 , Figure 6 As shown, the surface of the pin body 1 facing away from the electronic component 4 is a first arc surface 14; the pin insertion hole 31 of the tube 3 has a second arc surface on the side away from the electronic component 4; the curvature of the first arc surface 14 and the second arc surface are adapted to each other, so that when the pin body 1 is inserted into the pin insertion hole 31, the first arc surface 14 and the second arc surface form surface contact. Through the wide-area surface contact formed by the adaptation of the first arc surface 14 and the second arc surface, the impact load is uniformly distributed, effectively avoiding stress concentration, and significantly enhancing the ability of the end of the tube 3 to resist rupture and plastic deformation; by adopting this technical measure, the impact resistance of the tube packaging is further improved.

[0033] like Figure 1 , Figure 2 As shown, in actual use, the sealing pins can be configured differently depending on the length of the tube 3 and the degree of filling of the electronic components 4 inside the tube. For example, the load-bearing part 22 of the sealing pin can be placed on the outside of the end of the tube 3 to cooperate with the outer packaging.

[0034] like Figure 2As shown, a drop-resistant electronic component tube packaging includes a tube 3 with a recessed portion 33 and the aforementioned sealing pins. Pin insertion holes 31 are provided at both ends of the tube 3, corresponding to two sealing pins. The distance from the pin insertion hole 31 to the adjacent outer wall end face 34 is less than the length of the axial connecting section 21 of the sealing pin, and the distance from the pin body 1 to the load-bearing portion 22 is slightly greater than the distance from the pin insertion hole 31 to the outer wall end face 34. The load-bearing portion 22 is located on the outer side of the end of the tube 3 to cooperate with the outer packaging. By setting the "distance from the pin body 1 to the load-bearing portion 22" to be slightly greater than the "distance from the pin insertion hole 31 to the outer wall end face 34," and by placing the load-bearing portion 22 on the outer side of the end of the tube 3, when the tube packaging is subjected to a drop impact, the impact force will act directly on the outer packaging through the load-bearing portion 22. By adopting this technical measure, the impact force is prevented from acting directly on the fragile end opening of the tube 3 or the internal electronic components 4, thereby greatly improving the overall drop resistance.

[0035] In actual use, the distance from the pin body 1 to the load-bearing part 22 is 0.1mm to 0.5mm greater than the distance from the pin insertion hole 31 to the outer wall end face 34. This technical measure creates a clearance gap between the load-bearing part 22 and the outer wall end face 34 of the tube 3, while avoiding excessive compression on the end face of the tube 3. This allows the impact force to be smoothly transmitted to the housing, effectively preventing the end of the tube 3 from deforming due to rigid pressure.

[0036] Example 2 like Figure 8 As shown, the other contents of this embodiment are the same as those of Embodiment 1, except that: a drop-resistant electronic component tube package includes a tube 3 with a concave portion 33 and a sealing pin as in Embodiment 1; the tube 3 has pin insertion holes 31 at both ends, and a load-bearing portion insertion hole 32 is provided on the concave portion at one end; correspondingly, there are two sealing pins; the pin body of the sealing pin is embedded in the pin insertion hole; the load-bearing portion of the sealing pin at one end of the tube 3 is embedded in the load-bearing portion insertion hole; the load-bearing portion of the sealing pin at the other end of the tube 3 is provided on the outside of the end of the tube 3 to cooperate with the outer packaging.

[0037] In specific implementation, the two ends of the tube 3 are respectively provided with a first pin insertion hole 311 and a second pin insertion hole 312.

[0038] The sealing pin includes a first sealing pin 101 that mates with a first pin engagement hole 311 and a second sealing pin 201 that mates with a second pin engagement hole 312.

[0039] The distance from the first pin insertion hole 311 to the adjacent outer wall end face 34 is less than the length of the first axial connecting section 103 of the first sealing pin 101, and the distance from the first pin body 102 of the first sealing pin 101 to the first bearing part 104 is slightly greater than the distance from the first pin insertion hole 311 to the adjacent outer wall end face 34. The first pin body 102 of the first sealing pin 101 is embedded in the first pin insertion hole 311, and the first load-bearing part 104 is provided on the outer side of the end of the tube 3 to cooperate with the outer packaging.

[0040] The distance from the second pin insertion hole 312 to the adjacent outer wall end face 34 is greater than the length of the second axial connecting section 203 of the second sealing pin 201, and a load-bearing part insertion hole 32 is provided on the concave portion 33 between the second pin insertion hole 312 and the adjacent outer wall end face 34; the second pin body 202 of the second sealing pin 201 is embedded in the second pin insertion hole 312, and the second load-bearing part 204 of the second sealing pin 201 is embedded in the load-bearing part insertion hole 32.

[0041] In this embodiment, the tube 3 achieves both a flat and compact overall structure (with the load-bearing part embedded at one end) and ensures excellent impact resistance (with the load-bearing part exposed at the other end), thereby providing comprehensive and highly reliable drop protection for electronic components 4 within a limited space.

[0042] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
