In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.
[0025] Please refer to Figures 1 to 5 According to an embodiment of the present invention, the common-mode inductor structure with a protective shell and a base integrated therein comprises a protective shell 1, a base 2 and an inductor coil, wherein the protective shell 1 is provided with a hollow channel 13; the base 2 is integrally formed and connected with the protective shell 1, and the base 2 is provided with at least one pair of through holes 21, each through hole 21 passes through a side of the base 2 facing the protective shell 1 to a side of the base 2 facing away from the protective shell 1, and the through hole 21 is connected to an edge of the base 2 to form a lateral opening; the inductor coil is wound around the protective shell 1 through the hollow channel 13, a first flat wire 31 is led out from one end of the inductor coil, and a second flat wire 32 is led out from the other end, the first flat wire 31 is passed through one through hole 21, and the second flat wire 32 is passed through another through hole 21.
[0026] According to the common-mode inductor structure with integrated shell and base in the embodiment of the present invention, a hollow channel 13 is formed through the shell 1, so that the inductor coil can pass through the hollow channel 13 and be wound on the shell 1. At the same time, the bottom of the shell 1 is connected to the base 2, and the base 2 and the shell 1 are integrally formed to avoid the need to open two sets of different molds and reduce production costs. Since the inductor coil needs to lead out leads to form electrodes, the first flat wire 31 and the second flat wire 32 are respectively led out at both ends of the inductor coil. A through hole 21 is provided in the base 2 for fixing the first flat wire 31 and the second flat wire 32 to prevent their position from shifting. The through hole 21 is laterally connected to the side wall of the base 2 to form a lateral opening. In this way, the first flat wire 31 and the second flat wire 32 can be installed in the through hole 21 through the lateral opening and clamped. There is no need to align the ends of the first flat wire 31 and the second flat wire 32 with the through hole 21 for installation, thereby improving the convenience of installation.
[0027] In this embodiment, the protective shell 1 is a hollow annular structure, in which the two side columns of the hollow channel 13 can be used as winding areas, the inductor coil is wound on the protective shell 1, and at least the first flat wire 31 and the second flat wire 32 are led out, and the first flat wire 31 and the second flat wire 32 both pass through the through hole 21 on the base 2 to form an electrode. Exemplarily, the base 2 has bosses protruding on both sides of the protective shell 1, and the bosses are provided with through holes 21 to facilitate the first flat wire 31 and the second flat wire 32 to pass through. That is, according to one embodiment of the present invention, a pair of through holes 21 are respectively located on both sides of the protective shell 1, that is, one through hole 21 of the pair of through holes 21 is located on one side of the protective shell 1, and the other through hole 21 is located on the other side of the protective shell 1. The lateral openings of a pair of through holes 21 are arranged opposite to each other, so that the first flat wire 31 is led out from one side of the protective shell 1, and the second flat wire 32 is led out from the other side of the protective shell 1, so as to pass through the through holes 21 on both sides of the protective shell 1 respectively, thereby avoiding the first flat wire 31 and the second flat wire 32 from being entangled, and facilitating wire management.
[0028] It can be understood that the through hole 21 can be regarded as a slot structure opened on the side wall of the base 2, and the first flat wire 31 or the second flat wire 32 can be swung into the through hole 21 from the side, which is convenient for installation. If the through hole 21 is a closed circular hole, when the first flat wire 31 or the second flat wire 32 is inserted, it is necessary to align the end of the flat wire (referring to the first flat wire 31 or the second flat wire 32) with the through hole 21 for punching. On the one hand, the punching operation is not convenient for aligning the hole position, and on the other hand, when the length of the flat wire is long, it needs to be pulled for a long distance, and the installation operation is more complicated. For the through hole 21 with a side opening, it is only necessary to swing the corresponding position of the flat wire into the through hole 21 along the side opening, which improves the installation efficiency.
[0029] like Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, each through hole 21 includes a through hole 211 and a mounting channel 212, one end of the mounting channel 212 is connected to the through hole 211, and the other end extends toward the edge of the base 2 to form a lateral opening, and the width of the mounting channel 212 is smaller than the width of the through hole 211.
[0030] It should be noted that the installation channel 212 is formed with two oppositely disposed side walls, the width of the installation channel 212 refers to the distance between the two side walls, and the width of the through hole 211 is the width of the flat wire (referring to the first flat wire 31 or the second flat wire 32, when the first flat wire 31 or the second flat wire 32 is not specified below, the flat wire may refer to the first flat wire 31 or the second flat wire 32). Please refer to Figures 6 to 8As shown, when installing the flat wire, the flat wire can be placed vertically, swung into the installation channel 212 along the side, and the installation angle can be adjusted by tilting, so that the flat wire is placed in the penetration hole 211 for clamping and fixing. It can be understood that since the width of the installation channel 212 is smaller than the width of the penetration hole 211, the flat wire needs to be tilted at a certain angle and swung into the installation channel 212 during installation, and when it reaches the penetration hole 211, the flat wire is straightened, and the penetration hole 211 and the flat wire are adapted and clamped, and the flat wire is not easy to be separated from the installation channel 212 without rotating the flat wire.
[0031] Please continue to refer to Figure 5 According to one embodiment of the present invention, the installation channel 212 is flared in the direction close to the through hole 211. It can be understood that at one end of the installation channel 212 adjacent to the through hole 211, the two side walls thereof are inclined away from each other to facilitate the transition of the flat wire from the installation channel 212 to the through hole 211.
[0032] Please refer to Figure 1 and Figure 4 According to one embodiment of the present invention, the protective shell 1 is located on both sides of the hollow channel 13, which are respectively the first winding area and the second winding area, the base 2 is provided with two pairs of through holes 21, the inductor comprises a first coil 3 and a second coil 4, the first coil 3 is wound in the first winding area, one end of the first coil 3 leads to a first flat wire 31, the other end leads to a second flat wire 32, the first flat wire 31 is passed through one through hole 21 of a pair of through holes 21, and the second flat wire 32 is passed through the other through hole 21; the second coil 4 is wound in the second winding area, one end of the second coil 4 leads to a third flat wire 41, the other end leads to a fourth flat wire 42, the third flat wire 41 is passed through one through hole 21 of the other pair of through holes 21, and the fourth flat wire 42 is passed through the other through hole 21.
[0033] It can be understood that when the common mode inductor is used, the first coil 3 and the second coil 4 generate first magnetic flux lines with the same direction, and the first magnetic flux lines pass through the first coil 3 and the second coil 4 in sequence along the protective shell 1. In other words, the first flat wire 31 and the second flat wire 32 are led out from both ends of the first coil 3, and the third flat wire 41 and the fourth flat wire 42 are led out from both ends of the second coil 4. Two pairs of through holes 21 are opened on the base 2, and a total of four through holes 21 are provided to install the first flat wire 31, the second flat wire 32, the third flat wire 41 and the fourth flat wire 42. The multiple through holes 21 are arranged at intervals in the peripheral direction of the base 2, and can also be evenly distributed on both sides of the protective shell 1 to avoid interference between multiple flat wires.
[0034] According to one embodiment of the present invention, a first flat wire 31 is led out from the top of the first coil 3, a third flat wire 41 is led out from the top of the second coil 4, and the first flat wire 31 and the third flat wire 41 are located on the same side of the protective shell 1; a second flat wire 32 is led out from the bottom of the first coil 3, a fourth flat wire 42 is led out from the bottom of the second coil 4, and the second flat wire 32 and the fourth flat wire 42 are both located on the side of the protective shell 1 facing away from the first flat wire 31.
[0035] It can be understood that the flat wires led out from the top (referring to the first flat wire 31 and the third flat wire 41) are located on the same side of the protective shell 1, while the flat wires led out from the bottom (referring to the second flat wire 32 and the fourth flat wire 42) are located on the other side of the protective shell 1, and are mutually diverted to facilitate the arrangement of the line direction and avoid inconsistent lengths of the flat wires located on the same side of the protective shell 1.
[0036] Please refer to Figure 1 and Figure 2 According to one embodiment of the present invention, the common-mode inductor structure integrated with the protective shell base further includes a separator 5 , which is inserted into the hollow channel 13 , and the separator 5 is used to separate the first coil 3 and the second coil 4 .
[0037] It can be understood that the separator 5 is in the shape of a T-shaped plate, and part of it is inserted into the hollow channel 13 to separate the first coil 3 and the second coil 4. The length of the separator 5 is longer than the length of the hollow channel 13. Specifically, one end of the separator 5 abuts on the base 2, and the other end is provided with a mounting protrusion 52. The side wall of the mounting protrusion 52 abuts on the outer wall surface of the protective shell 1 to improve the installation stability. At the same time, the first flat wire 31 and the third flat wire 41 can be guided along the outer wall surface of the separator 5 to pass through the through hole 21 provided on the base 2 to prevent the first flat wire 31 and the second flat wire 32 from being easily bent. Specifically, the first flat wire 31 and the second flat wire 32 are led out from the hollow channel 13, bypass the separator 5, and abut on the side of the separator 5 facing away from the protective shell 1, which can play a role in fixing the separator 5.
[0038] like Figure 4 As shown, according to one embodiment of the present invention, the outer surface of the separator 5 is provided with a first wire groove 51 and a third wire groove 53 spaced apart from each other, and at least a portion of the first flat wire 31 is accommodated and confined in the first wire groove 51, and at least a portion of the third flat wire 41 is accommodated and confined in the third wire groove 53.
[0039] It can be understood that the first wire groove 51 and the third wire groove 53 both extend along the length direction of the separator 5, that is, extend from the top of the first coil 3 and the second coil 4 toward the base 2, so that the first flat wire 31 and the third flat wire 41 led out from the top are guided into the through hole 21. At the same time, the extension direction of the first wire groove 51 is set through a through hole 21, so that the first flat wire 31 can be directly passed through the through hole 21 after passing through the first wire groove 51 without adjusting the position. The third wire groove 53 is similar to the first wire groove 51 and will not be repeated here. The first wire groove 51 and the third wire groove 53 are both located on the side of the separator 5 away from the protective shell 1, which can limit the displacement of the first flat wire 31 and the third flat wire 41 in the left and right directions, thereby improving the installation stability of the first flat wire 31 and the third flat wire 41.
[0040] like Figure 2 As shown, according to one embodiment of the present invention, the common-mode inductor structure integrated with the housing base also includes a first glue-dispensing seal 6 and a second glue-dispensing seal 7 carried on the base 2, the first glue-dispensing seal 6 is used to connect and fix the first flat wire 31 and the third flat wire 41, and the second glue-dispensing seal 7 is used to connect and fix the second flat wire 32 and the fourth flat wire 42. It can be understood that while the first glue-dispensing seal connects and fixes the first flat wire 31 and the third flat wire 41, it can also be sealed at the through hole 21 to further prevent the first flat wire 31 and the third flat wire 41 from escaping from the through hole 21. The second glue-dispensing seal 7 is the same as the first glue-dispensing seal 6, and will not be repeated here.
[0041] like Figure 4 As shown, according to one embodiment of the present invention, the protective shell 1 and the base 2 are separately formed into a first shell 11 and a second shell 12, and the first shell 11 is connected with the second shell 12 by snapping. Exemplarily, the protective shell 1 and the base 2 can be split into the first shell 11 and the second shell 12 in the horizontal direction, and the first shell 11 is provided with a snap 111, and a snap hole is opened on the snap 111. The outer wall surface of the second shell 12 is correspondingly provided with a snap convex, and the snap hole on the snap 111 is matched with the snap convex to be snap-connected, which is convenient for installation. It should be noted that the first shell 11 and the second shell 12 both include a part of the protective shell and a part of the base, and the two are similar in shape, only the snap position structure is different. Specifically, a plurality of snaps 111 can be provided on the first shell 11, and a plurality of snap convex can be correspondingly provided on the second shell 12. The plurality of snaps 111 are matched with the plurality of snap convex to improve the connection stability.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
