It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship.

Referring to fig. 1 to 2, the present invention discloses a base 1 suitable for a chip common mode inductor, which includes two connecting seats 11 and a bottom plate 12 arranged at intervals. The bottom plate 12 is disposed between the two connecting sockets 11, and is used for connecting the two connecting sockets 11 and forming an i-shaped structure with the two connecting sockets 11. Two connecting seats 11 set up respectively on the tip of bottom plate 12, and two connecting seats 11 and bottom plate 12 enclose synthetic holding chamber 13 that is used for the holding magnetic core, and installation baffle 14 is erect along the direction of height of connecting seat 11 in the middle part of bottom plate 12, and this baffle 14 is used for separating two coil winding, and four corners of base 1 are equipped with pin 16 respectively, and base 1 is stretched out to the one end of each pin 16. Here, base 1 has formed the I-shaped structure through bottom plate 12 and connecting seat 11, and the four corners department of base 1 is equipped with the stitch respectively, is about to original contact pin formula change into SMD, has accorded with SMT technology production to satisfy common mode inductance's automated production requirement, and the chip mounter can absorb bottom plate 12 and assemble the operation, has solved the easy oblique problem outward of product well, thereby makes the overall dimension difference little between the product, does benefit to production and quality management and control.

Specifically, the central regions of the two ends of the bottom plate 12 are respectively provided with a card slot 121. Namely, the clamping groove 121 is reserved at the bottom of the base 1, so that when the insulating partition 14 needs to be added at the top of the base 1, the clamping groove 121 can be used for positioning.

In one embodiment, each lead 16 includes a first connecting portion 161 disposed on the upper surface of the connecting socket 11, and a second connecting portion 162 bent from one end of the first connecting portion 161 along the height direction of the connecting socket 11, wherein the second connecting portion 162 extends out of the base 1. That is, the second connecting portion 162 of the pin 16 penetrates from the top surface of the connector holder 11 and protrudes through the bottom surface of the connector holder 11, so that the connecting portion is mostly embedded in the connector holder 11, which facilitates the fixation of the pin 16 on the connector holder 11. Preferably, the first connection portion 161 and the second connection portion 162 are perpendicular to each other, i.e., the pin 16 has an inverted "L" shape, which facilitates the fabrication of the structure.

Further, a central region of the top surface of each connecting socket 11 is provided with a groove 111, and the end of the first connecting portion 161 far away from the second connecting portion 162 is exposed above the port of the groove 111. As shown in fig. 2, the groove 111 is provided between the two pins 16, which can ensure the flatness of the stitch patch during needle pressing.

Specifically, the pin 16 extends out of the middle of the extending section of the base 1 and is provided with arc notches 163 at two sides thereof. As shown in fig. 2, two arc notches 163 are disposed at two sides of the extending section of the second connecting portion 162 and located in the middle of the extending section, so as to prevent the coil winding from slipping out of the second connecting portion 162 after being wired.

As shown in fig. 1, arc-shaped side plates 15 are respectively disposed at both sides of the middle portion of each bottom plate 12. The arc-shaped side plates 15 support the coil windings, so that the coil windings are prevented from sinking, and the height consistency of products is ensured.

Furthermore, the bottom plate 12, the arc-shaped side plates 15 and the partition plates 14 are integrally formed, so that the processing technology is simplified, and the production efficiency is improved. And the stress concentration at the joint of the bottom plate 12, the arc-shaped side plate 15 and the partition plate 14 can be avoided by adopting an integrally-formed processing process.

The above description is only an alternative embodiment of the present invention, and should not be construed as limiting the present invention, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
