Description

Technical Field

[0001] The utility model relates to the technical field of optical coupler carrier tapes, in particular to an optical coupler carrier tape structure. Background Art

[0002] At present, in the process of optocoupler packaging, the main method used is to place the flat-bottom carrier tape into the carrier tape. Among them, the structure of the traditional flat-bottom carrier tape is as follows: Figure 1 As shown, during the packaging and transportation process and in some specific circumstances, such as during production and transportation, the flat carrier tape may accidentally slip out of the carrier tape and onto the ground. During the bumpy express logistics process, the carrier tape and components are easily deformed by gravity and inertia, resulting in the inability to effectively remove the optocoupler due to the deformation of the carrier tape, or the deformation of the optocoupler pins increases the height difference between the optocoupler pins, making it impossible to effectively tin the optocoupler. Utility Model Content

[0003] In response to the deficiencies of the prior art, the present invention provides an optical coupler carrier belt structure, which solves the problem that the existing flat-bottomed carrier belt cannot effectively protect the optical coupler, causing the optical coupler to easily fall or deform during transportation.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] An optical coupler carrier tape structure includes a carrier tape body as a mounting carrier, the carrier tape body is provided with a plurality of placement grooves for placing optical couplers, and bosses located between two pins at both ends of the optical coupler are provided in both ends of the bottom of the placement groove.

[0006] The length of the projection of the boss on the placement groove along the extension direction of the optocoupler pin is greater than the length of the projection of the pin at either end of the optocoupler on the placement groove along the extension direction of the optocoupler pin;

[0007] The width between the left and right sides of the bottom of the boss is greater than the gap between the two pins at either end of the optocoupler, and the width between the left and right sides of the top of the boss is smaller than the gap between the two pins at either end of the optocoupler.

[0008] Preferably, the gap between the center of the boss and the inner walls on the left and right sides of the placement groove is greater than half the width of the optical coupler.

[0009] Preferably, the height of the boss and the maximum height of the optocoupler pins range from -0.5 mm to 0.5 mm.

[0010] Compared with the prior art, the present invention provides an optical coupler carrier tape structure with the following beneficial effects:

[0011] 1. By setting the bosses at both ends of the bottom of the placement groove, the two bosses are respectively inserted between the two pins at both ends of the optocoupler to achieve the limitation of the optocoupler. When the optocoupler is placed in the carrier body for transportation, the two bosses can prevent the optocoupler from shaking during transportation, thereby greatly reducing the probability of the optocoupler sliding out of the placement groove and falling, and at the same time reducing the probability of the optocoupler pins being squeezed and deformed and damaged by the inner wall of the placement groove due to shaking, thereby greatly improving the yield of the optocoupler during transportation.

[0012] 2. By further setting the size range of the boss relative to the optocoupler and the placement groove, the optocoupler can be further stably supported, preventing the optocoupler pins from being squeezed and collided with the inner wall of the placement groove and deformed, thereby improving the yield of the optocoupler when transported in the carrier tape body.

[0018] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] In order to solve the problem that the existing flat-bottomed carrier belt cannot effectively protect the optical coupler, causing the optical coupler 4 to easily fall or deform during transportation, the utility model provides an optical coupler carrier belt structure, such as Figure 2 and Figure 3As shown, it includes a carrier belt body 1 as an installation carrier, and a plurality of placement grooves 2 for placing optical couplers 4 are provided on the carrier belt body 1. Bosses 3 located between the two pins at both ends of the optical coupler 4 are provided at both ends of the bottom of the placement groove 2. The two bosses 3 are respectively inserted into the two pins at both ends of the optical coupler 4 to limit the optical coupler 4. When the optical coupler 4 is placed in the carrier belt body 1 for transportation, the two bosses 3 can prevent the optical coupler 4 from shaking during transportation, thereby greatly reducing the probability of the optical coupler 4 sliding out of the placement groove 2 and falling, and at the same time reducing the probability of the optical coupler pin 5 being squeezed and damaged by the inner wall of the placement groove 2 due to shaking, thereby greatly improving the yield of the optical coupler 4 during transportation.

[0020] Although the presence of the boss 3 limits the movement of the optocoupler 4 to a certain extent, its effect is still relatively poor. Therefore, it is necessary to further limit the size of the boss 3. The projection of the boss 3 on the placement groove 2 is the length along the extension direction of the optocoupler pin 5, that is, Figure 2 and Figure 3 In the up and down direction, it is greater than the length of the projection of the pin at either end of the optocoupler 4 on the placement groove 2 along the extension direction of the optocoupler pin 5, thereby preventing the optocoupler pin 5 from colliding with the inner wall of the placement groove 2 on the side where the boss 3 is provided, thereby realizing the function of protecting the optocoupler pin 5.

[0021] In order to prevent the optocoupler pin 5 from being squeezed and deformed by the placement groove 2 when the optocoupler 4 is placed in the placement groove 2, the width between the left and right sides of the bottom of the boss 3 is larger than the gap between the two pins at either end of the optocoupler 4, and the width between the left and right sides of the top of the boss 3 is smaller than the gap between the two pins at either end of the optocoupler 4. Figure 2 and Figure 3 In the left and right directions of the middle boss 3, since the pin itself is a flat structure, it has a strong ability to resist lateral deformation. Therefore, the boss 3 is used to support the position between the two optocoupler pins 5 to prevent the optocoupler pins 5 from contacting the bottom wall of the placement groove 2, thereby preventing the optocoupler pins 5 from deforming in the height direction and in the lateral direction.

[0022] In order to prevent the optical coupler 4 from shaking on the boss 3, causing the optical coupler 4 and the left and right inner walls of the placement groove 2 to expand, the gap between the center of the boss 3 and the left and right inner walls of the placement groove 2 is made larger than half the width of the optical coupler 4.

[0023] When the height of the boss 3 is too high, the raised part is too high, resulting in the tool or hand being easily blocked by the boss 3 when the user removes the optocoupler 4, making it difficult to remove the optocoupler 4. When the height of the boss 3 is too low, the restricted area of ​​the boss 3 on the optocoupler 4 is reduced, and thus the limiting ability is weakened. Therefore, according to the conventional design size of the optocoupler 4 and experiments, the difference between the height of the boss 3 and the maximum height of the optocoupler pin 5 is in the range of -0.5mm to 0.5mm. Figure 3 The maximum height difference of the optical coupling pin 5 is the maximum height difference between two ends of the optical coupling pin 5.
