[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0023] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
[0024] like Figures 1 to 4 As shown, a novel I-shaped chip inductor includes: an inner core 1, a coil 2, a base 3, and a boss 4;
[0025] The inner core 1 is in an I-shape, and the bottom is fixedly connected to the top of the base 3;
[0026] The coil 2 is spirally wound on the inner core 1, with both ends extending to both sides of the base 3;
[0027] The base 3 is a regular hexagon with a circular concave in the center and two bosses 4 fixed on two opposite sides. When the base 3 is connected to the inner core 1, the bottom of the inner core 1 is adaptively placed in the circular concave to improve the stability of the connection between the two.
[0028] A groove 5 is provided between the boss 4 and the base 3 for winding the two ends of the coil extending to both sides of the base 3 .
[0029] The top of the boss 4 is provided with a bendable metal sheet 6. When the metal sheet 6 is bent, the thread ends wound around the groove 5 can be pressed between the metal sheet 6 and the top of the boss 4 to hide the thread ends and prevent them from falling off. The end of the metal sheet 6 extends outside the boss 4.
[0030] Furthermore, the coil 2 wound around the groove 5 is welded to the groove 5, with the welding point located on the bottom surface of the base 3. Specifically, a welding groove 7 is defined on the bottom surface of the boss 4. The welding groove 7 is located in the middle of the boss 4, with one side communicating with the groove 5. Preferably, the welding groove 7 is rectangular. The provision of the welding groove 7 accommodates solder, preventing the solder from protruding from the bottom surface of the inductor and disrupting its levelness.
[0031] Preferably, the bottom surface of the base 3 and the bottom surface of the boss 4 are located in the same plane, keeping the bottom surface of the inductor flush, preventing tilting during installation, and improving the stability of the inductor installation. Furthermore, the coil 2 wound on the groove 5 does not protrude from the groove 5, preventing the protruding coil 2 from disrupting the levelness of the inductor bottom.
[0032] Optionally, a wire pressing groove 8 is provided on the top of the boss 4, and the wire pressing groove 8 is located at the center of the top of the boss 4; the metal sheet 6 is provided in the wire pressing groove 8, and when the metal sheet 6 is bent, the wire end is pressed between the metal sheet 6 and the wire pressing groove 8.
[0033] When winding the coil 2, first press down one end of the thread, then wind around the groove 5 on one side, the inner core 1, the groove 5 on the other side in sequence, and finally press down the other end of the thread.
[0034] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
[0035] Finally, it should also be understood that certain technical features in the embodiments may not be necessary for solving specific technical problems, and thus these technical features may be absent or omitted without affecting the solution of the technical problem or the formation of a technical solution; moreover, the features, elements and / or functions of one embodiment may be appropriately combined, coupled or coordinated with the features, elements and / or functions of one or more other embodiments, unless the combination, coupling or coordination is obviously not feasible.
