Abstract

PURPOSE:To provide a memory card whose assembly process, for example, is not complicated, subsequently requiring no cost increase and free from such a trouble that a connector becomes disconnected easily from a frame. CONSTITUTION:A pair of panels 10,12 are adhered to the front and rear surfaces of a frame 4 so that a module substrate 6 and a connector 8 are stored. In addition, the connector 8 is set to connector mounting surfaces 4c, 4c through drop-off preventive parts 8a, 8a at the other ends of the right/left side parts 4a, 4a of the frame 4. Further, protrusions 4c, 4c are formed at the other ends of the right/left side parts 4a, 4a of the frame 4 and the connector is fixed to the frame 4 from a mounted state by pressing the connector against the top of the mooting parts 4c, 4c as the protrusions 4e, 4e are deformed to the connector 8 side.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory card used as an external storage medium for a computer.

0002

2. Description of the Related Art The conventional structure of this type of memory card will be explained with reference to FIGS. 3 and 4.

FIG. 3 is a plan view of the memory card, and FIG. 4 is a sectional view taken along line AA in FIG. 3 and viewed in the direction of the arrow.

As shown in these figures, a memory card 2
has a frame 4, a module board 6, a connector 8, and a pair of panels 10 and 12.

The frame body 4 is made of resin, and has left and right side portions 4a, which have a wall thickness that approximately corresponds to the wall thickness of the connector 8.
4a and rear side portion 4b are integral and form a frame. The left and right side portions 4a, 4a face each other in parallel with each other by a predetermined distance, and the rear side portion 4b is oriented perpendicularly to the left and right side portions 4a, 4a.

The memory card 2 has a module board 6 inside the frame 4 which has a rectangular frame shape in plan view.
A pair of metal panels 10 and 12 are attached to the front and back surfaces of the connector 8 and the connector 8 housed therein.

The module board 6 is a board on which electronic components such as semiconductor elements assembled according to various electric circuit configurations necessary for the operation of the memory card 2 are mounted. Consists of card parts. The connector 8 is called a two-piece connector in this example, and is connected to the module board 6. The specific state of connection between the connector 8 and the module board 6 is not shown.

The connector 8 has retaining portions 8a, 8 on both sides.
a protrudes and is housed in the frame 4 as described above, and a connector mounting surface is formed by cutting out a portion of the other end of each of the left and right sides 4a, 4a. 4c
, 4c are fitted with the retaining portions 8a, 8a to prevent them from coming off from the frame 4 in the front-rear direction (X-X' direction in the figure). 4d and 4d are notch spaces.

[0009]

By the way, in the memory card 2 having the above structure, the module board 6 and the connector 8 are simply housed in the frame 4, and the panels 10, 12 is not attached, the connector 8 is prevented from coming off from the frame 4 in the front-rear direction (X-X' direction in the figure) by its retaining parts 8a, 8a. Since it is simply placed on the connector mounting surfaces 4c, 4c formed on the other ends of the left and right sides 4a, 4a of the frame 4, it can be easily taken out upward (Z direction in the figure). It ends up.

It has been pointed out that the fact that the connector 8 can be easily removed from the frame 4 causes various troubles during the assembly process of the memory card 2. In order to eliminate such troubles, it would be better to have a structure in which the connector 8 cannot be easily removed from the frame 4, but a complicated structure would increase the cost of the assembly process.

Therefore, it is an object of the present invention to provide a memory card that does not require a structure that would complicate the assembly process of the memory card and increase costs, and in which the connector does not easily come off from the frame. The purpose is

0012

[Means for Solving the Problems] In order to achieve the above object, the memory card of the present invention has a frame body and a connector, and the frame body has a pair of panels on the front and back sides. The card components are stored inside by pasting the connector, and a connector mounting surface is formed on the other end of each of the left and right sides, and the connector is
The pair of panels are attached into the frame by the adhering with both side surfaces placed on the connector placement surfaces, respectively, and the frame also has a A protrusion is formed, and the connector also has a
It is characterized in that it is fixed to the frame by being pressed onto the placement surface by deformation of the protrusion toward the connector from the placement state.

[0013]

[Operation] The connector is fixed to the frame by the deformable protrusion at the other end with both sides placed on the connector mounting surfaces at the other end of the left and right sides of the frame.

[0014]

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIGS. 1 and 2 are side sectional views of a memory card according to an embodiment of the present invention, and FIG. 1 shows a case in which both sides of the connector are placed on the connector mounting surfaces at the other ends of the left and right sides of the frame. Figure 2 shows the connector fixed to the frame. In these figures, parts similar to or corresponding to those in FIGS. 3 and 4 according to the conventional example are given the same reference numerals, and detailed explanations of the parts having the same reference numerals will be omitted.

In the memory card 14 of this embodiment,
Protrusions 4e, 4e are formed at the other ends of the left and right sides 4a, 4a of the frame 4, and the retaining parts 8a, 8a on both sides of the connector 8, as shown in FIG. As shown in FIG.
By deforming upwards a and 8a, the retaining portion 8a
, 8a are fitted between the mounting surfaces 4c, 4c and the projections 4e, 4e, thereby fixing the connector 8 to the frame 4. If the frame body 4 is made of resin, this deformation can be performed by crushing it with heat, pressure, or both.

[0017]

[Effect of the invention] As is clear from the above explanation,
According to the present invention, with both sides of the connector placed on the connector mounting surfaces on the other end sides of the left and right sides of the frame,
Since the connector is fixed to the frame by the deformable protrusion at the other end, the connector cannot be easily removed from the frame in the upward direction (Z direction in FIG. 2). As a result, the present invention can provide a memory card without complicating the assembly process and increasing costs, and in which the connector does not easily come off from the frame.
