Description

Technical Field

[0001] This utility model relates to the field of optocoupler technology, and in particular to an optocoupler carrier strip. Background Technology

[0002] Currently, in the packaging process of optocouplers, the main method is to place the components inside the carrier belt. However, during the packaging and transportation process, and under certain circumstances, such as accidentally dropping the components from the table to the ground during production or during the bumpy ride of express logistics, the carrier belt and components are affected by gravity and inertia, which causes deformation of the carrier belt and component pins. This deformation further makes it difficult for the user to effectively remove the components when taking them out, and it also increases the height difference between the pins, making it difficult to solder them effectively, which seriously affects the performance and reliability of the components. Utility Model Content

[0012] Beneficial effects:

[0013] 1. This utility model, by setting a bearing groove and setting a limiting protrusion in the bearing groove, can prevent the pin from touching the side wall of the bearing groove when the component body is displaced, thus avoiding the side wall of the bearing groove being punctured and the pin being deformed. It plays a protective role for both the bearing belt body and the pin on the component body. In addition, the limiting protrusion can also enhance the pressure resistance of the inner wall of the bearing groove to a certain extent. Compared with the traditional planar bearing belt structure, its structural stability and functionality can be improved, which can greatly improve the deformation problem caused by the bearing belt under pressure, drop, and logistics bumps.

[0014] 2. By optimizing the size of the bearing groove, this utility model can ensure that the shell can be placed stably in the bearing groove, while leaving a certain gap to avoid the difficulty of inserting the component due to the size being too tight. When the user wants to retrieve the component, the component can be easily taken out of the bearing groove, reducing the time and difficulty of retrieving the component. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] When packaging optocouplers, the main method is to place the components inside the carrier strap. Traditional flat-bottomed carrier straps lack a structure to limit the pins of the components. During packaging and transportation, the carrier strap and the pins of the components are easily deformed, which affects the subsequent removal of the components. At the same time, it will increase the height difference between the pins, making it impossible to effectively tin them, thus affecting the performance and reliability of the components.

[0026] To address the aforementioned defects in the use of the bearing belt, please refer to [link / reference needed]. Figures 1-7This utility model provides an optocoupler carrier strip that increases the carrier strip's resistance to pressure and deformation, while reducing the possibility of component deformation within the carrier strip, thus ensuring the component's performance. The carrier strip is based on a carrier strip body 1 and a component body 2. The carrier strip body 1 has multiple carrier grooves 3 for placing the component body 2. The openings of the carrier grooves 3 are wider at the top and narrower at the bottom to facilitate placement of the component body 2. Trapezoidal limiting protrusions 4 are fixedly installed on both sides of the interior of the carrier grooves 3. The top and bottom of the limiting protrusions 4 are respectively provided with an upper plane 41 and a lower plane 42. A slope a43 is provided on the inner side of the limiting protrusions 4, and a pair of slopes b44 are provided on the outer side of the limiting protrusions 4. The component body 2 includes a shell 21 placed within the carrier strip body 1. The shape of the shell 21 matches the slopes a43 and b44. A pair of pins 22 are installed on both sides of the shell 21. The two limiting protrusions 4 are respectively positioned between the two pairs of pins 22. The two pins 22 on the same side are separated by the limiting protrusion 4, so that the pins 22 are stuck between the inner wall of the bearing groove 3 and the limiting protrusion 4. This can limit the movement of the pins 22 when the component body 2 moves within the bearing groove 3, preventing the pins 22 from touching the side wall of the bearing groove 3, avoiding puncture of the side wall of the bearing groove 3 and deformation of the pins 22. This protects both the bearing belt body 1 and the pins 22 on the component body 2. In addition, the limiting protrusion 4 can also enhance the pressure resistance of the inner wall of the bearing groove 3 to a certain extent. Compared with the traditional planar bearing belt structure, its structural stability and functionality can be improved, which can greatly improve the deformation problem caused by the bearing belt under pressure, drop, and logistics bumps.

[0027] To ensure the stable placement of component body 2, the dimensions of the support groove 3 on the support belt 1 and the component body 2 require precise calculation and optimization. Please refer to [link / reference needed]. Figures 3-7 The maximum width of the housing 21 is set to A, the maximum length of the housing 21 is set to B, the maximum length of the component body 2 is set to C, the bottom width of the bearing groove 3 is set to A0, and the bottom length of the bearing groove 3 is B0; A0 = A + 0.3mm, B0 = C + 0.5mm, the bottom length of the housing 21 is set to E, the distance between the two upper planes 41 is set to B1, and the distance between the two lower planes 42 is set to B2; B1 = B + 0.15mm, B2 = E + 0.15mm, B0 - B2 = L1, CE = L2, where L1 is greater than L2. This size setting can ensure that the housing 21 can be stably placed in the bearing groove 3, while leaving a certain gap to avoid the component body 2 being difficult to insert due to excessive tightness. When the user takes out the component body 2, it can also be easily removed from the bearing groove 3.

[0028] In addition to ensuring the stability of the housing 21, it is also necessary to ensure the stability of the pins 22. Therefore, the spacing between a pair of pins 22 is set to F, the width of the lower plane 42 is set to A1, and the width of the upper plane 41 is set to A2; A1 = F - 0.4mm, A2 = A1 - 0.4mm. This can effectively separate and fix the pins 22, while avoiding excessive pressure on the housing 21. The pins 22 can be stuck between the inner wall of the bearing groove 3 and the limiting protrusion 4, preventing the pins 22 from touching the side wall of the bearing groove 3, preventing the pins 22 from deforming, and not affecting the removal of the pins 22.

[0029] Reference Figure 4 and Figure 7 As shown, the maximum height of component body 2 is set to D, and the maximum depth of the bearing groove 3 is set to K0; K0 = D + 0.5 mm. A packaging line 23 is provided on the outer side of the housing 21, with the height of the packaging line 23 set to G. The height of the limiting protrusion 4 is set to K1; K1 = G + 0.1 mm. This ensures that the bearing groove 3 can completely accommodate component body 2 while leaving sufficient space to prevent deformation of the bearing groove 3 due to excessive component height.
