Abstract
Description
Technical Field
[0001] This utility model relates to the field of transistor technology, specifically to a transistor holder with anti-loosening positioning. Background Technology
[0002] With the increasing power density of power supply products and the growing demands for EMI protection in application environments, coupled with the increasing number of transistors in use each year, the electrical protection issues of transistors are becoming increasingly prominent. On the one hand, existing transistor sockets do not provide space for installing ferrite beads, making it impossible to install filter beads to resist EMI interference. On the other hand, commercially available transistor sockets typically only have slots for inserting transistor pins without a fastening structure, making it easy for pins to loosen during operation. Furthermore, the lack of a positioning structure means that pins can easily shift left or right after being installed in the transistor socket, requiring repeated manual installation and adjustment, which wastes manpower. Therefore, there is an urgent need for a transistor socket with anti-loosening and positioning features to solve these problems. Utility Model Content
[0003] In view of this, a robust, reliable, easy-to-assemble, and anti-loosening transistor holder with positioning is provided to resist EMI interference.
[0004] A transistor holder with anti-loosening positioning is used to secure the pins of diodes or transistors. The transistor holder has a first pin hole, a second pin hole, and a pin positioning hole. The first pin hole, the second pin hole, and the pin positioning hole correspond to the positions of the three pins of the transistor. The first pin hole and the pin positioning hole correspond to the positions of the two pins of the diode. The first pin hole and the second pin hole each have built-in bosses for securing the pins. A magnetic bead avoidance area is provided below the first pin hole for mounting a filter magnetic bead.
[0005] Furthermore, each of the first pin hole and the second pin hole has at least two protrusions built in, the two protrusions are symmetrically arranged, and the pin is inserted into the gap between the two protrusions.
[0006] Furthermore, all the bosses are elastic bosses, and the diameter of the pin is slightly larger than the gap between the bosses so that when the pin is inserted, the boss can fasten the pin.
[0007] Furthermore, the diameter of the pin positioning hole is slightly larger than the diameter of the pin.
[0008] Furthermore, the diameter of the first pin hole is the same as the diameter of the second pin hole, and the diameter of the first pin hole is larger than the diameter of the pin positioning hole.
[0009] Furthermore, the first pin hole, the second pin hole, and the pin positioning hole are all through holes, and the depth of the first pin hole is less than the depth of the second pin hole so that space can be reserved below the first pin hole for the magnetic bead avoidance area.
[0010] Furthermore, the boss and the transistor base are integrally formed.
[0011] Furthermore, the filter bead is a hollow bead, and the diameter of the first pin hole is less than or equal to the inner diameter of the hollow bead.
[0012] Furthermore, the center of the first pin hole and the center of the filter bead are on the same vertical center line.
[0013] Furthermore, the filter bead does not protrude from the side and bottom of the transistor mount after being inserted into the bead avoidance area.
[0014] Compared with the prior art, the present invention has at least the following beneficial effects:
[0015] First, this type of anti-loosening and positioning transistor socket has bosses in the first and second pin holes to secure the pins and prevent them from coming loose during operation. It also has pin positioning holes, which can be used for alignment and positioning when the pin is inserted, preventing the pin from shifting left or right after it is installed. This avoids repeated manual installation and adjustment, improves installation efficiency, reduces rework rate, and saves labor costs.
[0016] Secondly, this type of anti-loosening and positioning transistor socket has a ferrite bead avoidance area below the first pin hole for installing filter ferrite beads, which also enhances the transistor's ability to resist EMI interference, improves the protection effect of the transistor socket, and reduces the impact of EMI.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1 to 4 This illustration shows an embodiment of the present invention providing a transistor holder 1 with anti-loosening positioning for securing the pins 6 of a diode 11 or a transistor 10. The transistor holder 1 has a first pin hole 2, a second pin hole 3, and a pin positioning hole 4. The first pin hole 2, the second pin hole 3, and the pin positioning hole 4 correspond to the positions of the three pins 6 of the transistor 10. The first pin hole 2 and the pin positioning hole 4 correspond to the positions of the two pins 6 of the diode 11. The first pin hole 2 and the second pin hole 3 each have a built-in boss 5 for securing the pins 6. A magnetic bead avoidance area 9 is provided below the first pin hole 2 for installing a filter magnetic bead 7.
[0025] In some specific embodiments, when transistor 10 is inserted into transistor socket 1, it is aligned with pin positioning holes 4, and one pin 6 is inserted into pin positioning holes 4 accordingly. The remaining two pins 6 are automatically inserted into the first pin hole 2 and the second pin hole 3 respectively, and the pins 6 are secured by the boss 5. When diode 11 is inserted into transistor socket 1, it is aligned with pin positioning holes 4, and one pin 6 is inserted into pin positioning holes 4 accordingly. The remaining pin 6 is automatically inserted into the first pin hole 2, and the pins 6 are secured by the boss 5. Pin positioning holes 4 play an alignment role during the installation process, improving assembly efficiency. Pin positioning holes 4 also play a positioning role. During the operation after transistor is installed into transistor socket 1, since one pin 6 is inserted into pin positioning holes 4, even if the transistor is accidentally touched, the pin 6 will not shift left or right.
[0026] Specifically, the first pin hole 2 and the second pin hole 3 each have at least two protrusions 5 built into them, the two protrusions 5 are symmetrically arranged, and the pin 6 is inserted into the protrusion gap 8 between the two protrusions 5.
[0027] More specifically, all the bosses 5 are elastic bosses, and the diameter of the pin 6 is slightly larger than the gap between the bosses 5 so that when the pin 6 is inserted, the bosses 5 can fasten the pin 6.
[0028] In some specific embodiments, the transistor base 1 and the boss 5 are preferably made of nylon PA66, nylon PA9T or polybutylene terephthalate PBT with good elasticity. When the pin 6 is inserted into the boss gap 8, the two bosses 5 will clamp the pin 6 to secure the pin 6 in the first pin hole 2 and the second pin hole 3. At the same time, the elastic bosses 5 will not damage the pin 6.
[0029] Specifically, the diameter of the pin positioning hole 4 is slightly larger than the diameter of the pin 6.
[0030] Specifically, the diameter of the first pin hole 2 is the same as the diameter of the second pin hole 3, and the diameter of the first pin hole 2 is larger than the diameter of the pin positioning hole 4.
[0031] Specifically, the first pin hole 2, the second pin hole 3, and the pin positioning hole 4 are all through holes. The depth of the first pin hole 2 is less than the depth of the second pin hole 3 so that space can be reserved below the first pin hole 2 for the magnetic bead avoidance area 9.
[0032] In some specific embodiments, the magnetic bead avoidance area 9 can not only be set below the first pin hole 2, but can also be set separately below the second pin hole 3 or the pin positioning hole 4 according to actual needs; in addition, the magnetic bead avoidance area 9 can also be set below multiple holes at the same time, such as below the first pin hole 2 and the pin positioning hole 4, and multiple filter magnetic beads 7 can be set below multiple holes to further enhance the anti-EMI capability.
[0033] Specifically, the boss 5 and the transistor base 1 are integrally formed.
[0034] Specifically, the filter bead 7 is a hollow bead, and the diameter of the first pin hole 2 is less than or equal to the inner diameter of the hollow bead.
[0035] Specifically, the center of the first pin hole 2 and the center of the filter bead 7 are on the same vertical center line.
[0036] Specifically, the filter bead 7 does not protrude from the side and bottom of the transistor holder 1 after being inserted into the bead avoidance area 9.
[0037] In summary, this anti-loosening and positioning transistor holder 1 has protrusions 5 in the first pin hole 2 and the second pin hole 3 to secure the pin 6, thus preventing the pin 6 from loosening during operation. It also has pin positioning holes 4, which align and position the pin 6 during insertion, preventing it from shifting left or right after insertion. This avoids repeated manual installation and adjustment, improving installation efficiency, reducing rework, and saving labor costs. Furthermore, the anti-loosening and positioning transistor holder 1 has a ferrite bead avoidance area 9 below the first pin hole 2 for installing a filter bead 7, which enhances the transistor's ability to resist EMI interference, improves the protection effect of the transistor holder 1, and reduces the impact of EMI.
[0038] It should be noted that this utility model is not limited to the above-described embodiments. Based on the inventive spirit of this utility model, those skilled in the art can make other changes, and these changes made based on the inventive spirit of this utility model should be included within the scope of protection claimed by this utility model.
