Embodiment Construction

[0039] Figure 7 An embodiment of a modular electronic device according to the invention is shown. This embodiment is shown in the form of a modular electronic device 20 . The modular electronic device 20 is obtained as a resin molding that can be easily coupled with and detached from a connector provided on an electronic device such as a personal computer, for example, for a card-type information recording medium.

[0040] Such as Figure 7 The illustrated modular electronic device has an upper part 21 , a lower part 22 and a bottom plate 23 shaped as a rectangle and placed between the upper part 21 and the lower part 22 . A plurality of terminals 24 and a plurality of isolation ribs 25 are fixed and arranged on the bottom plate 23 . Each of the terminals 24 is placed between a pair of ribs 25 adjacent to each other, although in Figure 7 not shown in A plurality of ribs 25 , upper part 21 and lower part 22 constitute an integral resin molded part, and upper part 21 and ...

Abstract

A method of forming a module electronic component comprising a substrate (23) having a plurality of terminal parts (24) with curved tip parts (24a) arranged thereon and resin formed portions (21, 22) covering the substrate (23) with the plurality of terminal parts (24) exposed to the outside, comprising the steps of, when a mold space storing the substrate (23) as a formed material is formed by moving a cope (30) and a drag (31) from a mutually separated state to a mutually contact state, applying a press-forming to the tip corner parts (24a') of the plurality of end parts (24) arranged on the substrate (23), filling molten resin (36) in the mold space storing the substrate (23) with the curved parts (30R) brought into close contact with the portions thereof where the tip corner parts (24a') were formed, and separating the cope (30) and the drag (31) from each other after the molten resin (36) has been solidified.

Description

technical field [0001] The present application relates to a method of molding modular electronic devices, each of which can be easily coupled to and detached from connectors provided on the electronic device, for example for storing data therein and reading therefrom An information recording medium for acquiring data, and also relates to a device molded by the method or a modular electronic device molded by the method. Background technique [0002] A variety of modular electronic devices have been widely disseminated, each of which can be easily coupled to and detached from connectors provided on electronic devices such as personal computers, information recording and reproducing devices, etc., For use in, for example, a card-type information recording medium that operates under the condition of being electrically connected to an electronic device. For example, one of the previously proposed modular electronics such as figure 1 and 2 constructed as shown. [0003] refer ...
