Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, and in particular to a base structure for improving pressure resistance applications. Background Technology

[0002] In the field of electronic components (inductors, transformers, etc.), the creepage distance between the pins directly affects the voltage withstand performance of the components.

[0003] In the existing component base design, the distance between the hanging pins is short. When the component winding is connected to the hanging pin, the creepage distance between the pins is insufficient, which cannot meet the requirements of high voltage applications.

[0004] Therefore, it is necessary to design a base with a boss structure concept, which has a creepage distance from the original high-voltage base design, thereby improving the product's high-voltage application. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a base structure for improving pressure resistance, comprising a base body, wherein the base body is provided with a coil placement position and a plurality of hanging pins; The base body is also provided with multiple protrusions, which are located between each hanging pin to increase the creepage distance between each hanging pin.

[0007] As a further embodiment of this utility model: at least two hanging pins are provided and distributed at the corners of the bottom surface of the base body.

[0008] As a further embodiment of this utility model: the plurality of protrusions are respectively arranged in an L-shaped structure at the corners of the bottom surface of the base body, so as to surround the corresponding hanging wire PIN at the corners of the bottom surface of the base body.

[0009] As a further embodiment of this utility model: the bottom surfaces of the plurality of protrusions are flush, and the bottom end of the hanging pin is lower than the bottom surface of the protrusion.

[0010] As a further embodiment of this utility model: the base body is provided with a plurality of wire inlet grooves corresponding to the hanging pins.

[0011] As a further embodiment of this utility model: one of the bosses has a foot notch at its corner.

[0012] As a further embodiment of this utility model: a placement platform is provided on the coil placement position, and the placement platform has an arc-shaped groove.

[0013] Compared with the prior art, the beneficial effects of this technical solution are as follows: when the component acts on the circuit, the boss forms a raised barrier on the insulating surface between each hanging pin, which can extend the surface path between each hanging pin, that is, increase the creepage distance between the hanging pins, thereby improving the withstand voltage performance of the product to meet the high voltage electrical safety standards and the requirements of high voltage application of the product. Meanwhile, after the hanging pin is inserted into the connection hole on the PCB and soldered, the bottom surface of the boss can fit perfectly against the surface of the PCB. The bottom surfaces of multiple bosses are flush, which increases the contact area with the PCB and avoids the problem of component shaking or tilting caused by uneven local force. This improves the overall support stability of the component on the PCB and reduces the risk of solder joint detachment or component displacement caused by vibration, external force collision, etc. during subsequent use.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-3A base structure for improving pressure resistance applications includes a base body 1, on which a coil placement position 2 and a plurality of hanging pins 3 are provided; The base body 1 is also provided with a plurality of protrusions 4, which are located between each hanging wire PIN3 to improve the creepage distance between each hanging wire PIN3.

[0019] Specifically, the size of the coil placement position 2 matches the outer diameter and thickness of the coil. After the coil is placed, it will be limited by the coil placement position 2. Then, epoxy resin glue is added to reinforce the coil and the coil placement position 2, thereby preventing the coil from shifting or loosening during use and ensuring the relative position of the coil is stable. After stabilizing the coil, the connecting wire is led out from the coil and connected to the hanging wire PIN3 (soldering fixation) to form a complete and usable component (such as an inductor). When the component is mounted on the PCB board, the hanging wire PIN3 is reliably electrically connected to the PCB board to ensure that the current is stably transmitted between the internal coil and the external circuit of the component. When the component acts on the circuit, the boss 4 forms a raised barrier on the insulating surface between each hanging wire PIN3, which can extend the surface path between each hanging wire PIN3, that is, increase the creepage distance between the hanging wire PIN3, thereby improving the withstand voltage performance of the product to meet the high voltage electrical safety standards and the requirements of high voltage application of the product.

[0020] Based on the above embodiments, it is further proposed that at least two hanging wire PIN3s are provided and distributed at the corners of the bottom surface of the base body 1; Multiple protrusions 4 are respectively arranged in an L-shaped structure at the bottom corner of the base body 1, and the corresponding hanging wire PIN3 is surrounded at the bottom corner of the base body 1.

[0021] Specifically, the boss 4 is designed as an L-shaped structure and is placed near the corner of the bottom surface of the base body 1. Its L-shaped structure encloses an area at the corner of the bottom surface of the base body 1, thereby surrounding the hanging wire PIN3 at the corner. This can maximize the creepage distance between each hanging wire PIN3 and achieve the effect of maximizing the voltage withstand performance of the component.

[0022] Preferably, the number of hanging pins 3 can be 4 or 6, such as Figure 2-3 As shown, taking a quantity of six as an example, four of them are distributed at the four corners of the bottom surface of the base body 1, and the other two are located between the hanging wires PIN3 at the corners. At the same time, there are four bosses 4, and their L-shaped structure is set at the four corners to form an enclosure of the hanging wires PIN3 at the corners.

[0023] Based on the above embodiments, it is further proposed that the bottom surfaces of the multiple bosses 4 are flush, and the bottom end of the hanging wire PIN3 is lower than the bottom surface of the bosses 4.

[0024] Specifically, since the bottom of the hanging pin 3 is lower than the bottom surface 4 of the boss, after the hanging pin 3 is inserted into the connection hole on the PCB and soldered, the bottom surface of the boss 4 can fit perfectly against the surface of the PCB. The PCB with the bottom surfaces of multiple bosses 4 being flush is in uniform contact, which increases the contact area with the PCB and avoids the problem of component shaking or tilting caused by uneven local force. This improves the support stability of the entire component on the PCB and reduces the risk of solder joint detachment or component displacement caused by vibration, external force collision, etc. during subsequent use.

[0025] Furthermore, the base body 1 is provided with multiple wire inlet slots 5 corresponding to the hanging wire PIN3.

[0026] Specifically, a corresponding inlet slot 5 is opened in the base body 1 for each hanging PIN3 to clarify the direction of the coil connection wire, ensure that the connection wire is accurately connected to the corresponding hanging PIN3, and avoid misconnection.

[0027] Furthermore, one of the bosses 4 has a notch 6 at one of its corners. The structural feature of the notch 6 clarifies the mounting direction of the component and prevents errors in the mounting direction.

[0028] Furthermore, a placement platform 21 is provided on the coil placement position 2, and the placement platform 21 has an arc-shaped groove 22.

[0029] Specifically, the arc-shaped groove 22 designed on the placement platform 21 matches the shape of the coil. After the coil is placed in the arc-shaped groove 22, its position is restricted so that the coil can be kept in the preset position when using epoxy resin glue, and avoid displacement.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
