Abstract
The utility model relates to an inductor. Wherein, two corresponding E-shaped magnetic cores (7) are provided, a frame (2) winded with a coil (3) is inserted, the coil is draw out by a post head (1). The utility model is characterized in that: posts (7-1) and (7-2) at the two sides of the E-shaped magnetic core are connected with each other, an air gap is left between each two middle posts (7-3). A glue sticking layer (4) can also be arranged between the posts at the two sides of the E-shaped magnetic core. The utility model not only improves the assembly speed, but also ensures the consistency of inductance in products with batches and the stability of a single product in use.
Description
Technical field
The utility model relates to a kind of inductor.
Background technology
Existing EE type inductor has two relative E shape magnetic cores mostly, inserts the skeleton that is wound with coil, is lined with air gap paper between three posts of E shape magnetic core left, center, right.The way of cushion steam crack paper has following deficiency: the one, and thickness is difficult to control, makes the inductance value with a collection of product produce fluctuation easily; The 2nd, air gap paper thickness is subjected to temperature, humidity effect easily, and then can make inductance value instability in the single product use; The 3rd, influenced assembling speed, production efficiency is not high enough.
Summary of the invention
Inductor of the present utility model has two relative E shape magnetic cores, inserts the skeleton that is wound with coil, and coil is drawn by binding post, it is characterized in that described E shape magnetic core two side columns contact, and have air gap between the center pillar.Air gap can be processed by special purpose grinder, and is stable to guarantee gap value; E shape magnetic core two side columns contact, and except having improved assembling speed, also make the inductance value of bulk article that consistency is arranged, stable being guaranteed during single product uses.Between described magnetic core two side columns adhesive-layer is arranged, both sides are directly affixed, even using under the temperature more than 100 ℃, inductance value also is difficult for changing.The coiling of described coil is a multi cord, can change the high frequency characteristics of product.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
