Problems solved by technology

In addition, due to the embedding pressure of the embedding resin material, deformation or cracks occur in the positioning shape, so that there is a problem that the electrical conduction with the terminal cannot be ensured, or the first resin mold may not completely cover the second resin mold and be exposed (no modeling)

Embodiment Construction

[0013] Below, according to Figure 1 to Figure 4 One embodiment that embodied the present invention will be described. Figure 1 ~ Figure 4 It is one embodiment which actualized this invention.

[0014] figure 1 as well as figure 2 is a diagram showing a rotation angle detection device to which this embodiment is applied, figure 1 represents a top view, figure 2 means along figure 1 Cross-sectional view of line B-B. Such as Figure 1 ~ Figure 4 As shown, a rotating shaft 12 fixed to a rotatable object to be detected (not shown) is supported via a bearing 13 by a housing 11 constituting a housing on the main body side of the rotation angle detecting device. Furthermore, a substantially bottomed cylindrical yoke (yoke) 14 made of a magnetic material such as iron is fixed to the front end portion of the rotating shaft 12 coaxially with the rotating shaft by caulking or the like. figure 2 Middle is the upper end). A substantially cylindrical resin body 15 is fixed coax...

Abstract

A holding structure for an electronic part includes a first resin mold which has a positioning shape portion for the electronic part, and a second resin mold which is insert-molded to cover the first resin mold and the electronic part positioned with the first resin mold. Through holes for passing an insert resin material adapted to form the second resin mold is formed in the positioning shape portion of the first resin mold. The holding structure for the electronic part improves the positioning accuracy of the electronic part by virtue of the positioning shape portion for accommodating the electronic part, and prevents occurrence of deformations and cracks in the positioning shape portion due to insert-molding.

Description

technical field [0001] The present invention relates to a holding structure for electronic components and a holding method for electronic components. Background technique [0002] As a conventional holding structure of an electronic component, for example, the holding structure of an electronic component described in Patent Document 1 (JP-A-2003-172634) is known. That is, the holding structure described in this gazette includes: insert-molding with the terminal (terminal) (23) as a reference, and having a positioning shape part with electronic components (22, 25) electrically connected to the terminal (23) (24a, 24b) first resin mold (24, electronic component, fixed terminal model); and surround the first resin mold (24) and be electrically connected to the terminal (23) by the first resin mold (24) positioning ) electronic components (22, 25) and the holding structure of the electronic components of the second resin mold (21, connector housing) insert-molded based on the t...
