Abstract

PURPOSE:To prevent false certification by radiating light having at least the same broadening as an LED when a card ejector attached to a card side makes emitted light of the LED mounted on a card end part pass through. CONSTITUTION:Light 103 emitted from and LED 102 is radiated from a card ejector in a radiation range A as light 104 having at least the same broadening as the light 103 by passing through a concave lens 302 provided integrally to a card ejector 301.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card ejector, and more particularly to a card ejector mounted on the side of a card and capable of easily confirming the light emission of an LED mounted on the end of the card.

[0002]

2. Description of the Related Art FIG. 4 is a perspective view showing an example of a conventional card ejector. As shown in FIG. 4, the card ejector of this example is provided with a hole 304 corresponding to the position of the LED 102 mounted on the end of the card 101.
Through this, the light emission of the LED 102 was confirmed.

FIG. 5 is a partial sectional view showing the relationship between the hole of the card ejector and the LED in FIG. In this conventional card ejector, the light 1 emitted from the LED 102 is
03 becomes narrow light 105 having an emission range B by passing through the hole 304.

[0004]

In this conventional card ejector, to confirm the light emission of the LED, it is necessary to directly look at the LED through the hole of the card ejector, and the light in an extremely narrow confirmable area is confirmed. There was a problem that there were many false positives.

[0005]

According to the card ejector of the present invention, a connector having male or female contacts is attached to one side of a printed circuit card, and the card is inserted into the other side of the card. A card assembly to which a card ejector having lock and eject functions is attached, and a connector having a female or male contactor that guides and accommodates a plurality of the card assemblies and can be fitted with the connector when the card assemblies are inserted A card ejector comprising a shelf to which a back panel to which is attached is fixed, wherein a lens portion made of a transparent or translucent material is integrally formed at a position corresponding to an LED mounted on an end portion of the card. To do.

The lens portion may be either a concave lens or a Fresnel lens.

[0007]

The present invention will be described below with reference to the drawings. FIG. 1 is a partial cross-sectional perspective view showing a usage example of the card ejector of the present invention.

In this example of use, a card 10 having a printed wiring is used.
A card assembly 401 in which a connector 201 having a female contactor is attached to one side and a card ejector 301 having an insertion lock and eject function of the card 101 is attached to the other side, and a plurality of card assemblies 401 are guided. A shelf 701 to which a back panel 601 having a connector 501 having a male contactor capable of fitting with the connector 201 when the card assembly 401 is inserted and the card assembly 401 is inserted is fixed.

The card ejector 301 is made of a transparent material and has the LED 1 mounted on the end of the card 101.
02 has a lens portion 300, which corresponds to the position 02, in an integrated structure.

FIG. 2 is a partial cross-sectional view showing the relationship between the lens portion and the LED showing the first embodiment of the present invention. In this embodiment, the lens portion 300 (shown in FIG. 1) forms the concave lens 302.

The light 103 emitted from the LED 102 passes through the concave lens 302 and is emitted as the light 104 in the emission range A having a spread equal to or larger than that of the light 103.

Next, FIG. 3 is a partial cross-sectional view showing a relationship between a lens portion and an LED showing a second embodiment of the present invention. In this embodiment, the lens portion 300 (shown in FIG. 1) forms the Fresnel lens 303.

In the first embodiment, when the transparency of the material of the card ejector (lens portion) is low or the luminous intensity of the LED is low, the light emitted from the LED 102 is reflected by the concave lens 302 when passing through the concave lens 302. It is absorbed and the amount of light for confirmation is reduced.

On the other hand, in the second embodiment, the Fresnel lens 303 has a reduced thickness portion as compared with the concave lens 302 in FIG. 2, so that the amount of light when the light 103 passes through the Fresnel lens 303 is less reduced. When the transparency of the material of the card ejector 301 is low or the LED 102
Even if the luminous intensity is low, it is possible to obtain the light 104 having the same emission range A as in the case of the concave lens.

[0015]

As described above, according to the present invention, a card ejector made of a transparent or translucent material is provided with a lens portion, which is positionally corresponding to the LED mounted on the end portion of the card, in an integrated structure. , Even if the light emitted from the LED passes through the lens, it can be emitted as light having a spread equal to or larger than the light emitted from the LED.
This has the effect of eliminating erroneous confirmation of ED light emission.
