Problems solved by technology

Therefore, when viewed from the side where the light guide 24 passes and the side opposite to the side, the visibility is poor, and good visibility in all directions cannot be obtained.
[0009] In addition, since the upper surface of the relay 21 emits light, when a plurality of relays 21 are arranged in a row, it is less likely to be blocked by adjacent relays than the relays in FIG. 1 .
However, sometimes depending on the configuration relationship between the relays, it is difficult to know which relays are lit.
For example, when the relays are arranged in such a way that their sides face each other, the light guide part is located between adjacent relays, so the display surface 26 emits light between adjacent relays, making it difficult to judge which relay is emitting light.
[0010] In addition, in the relay 21, the end of the upper surface emits light in a point shape, so if there is reflection caused by ambient light near the light emitting point, the light emitted by the relay is affected by the ambient light and is difficult to observe.

Embodiment approach 1

[0075] Below, refer to Figure 4-Figure 8 The relay according to Embodiment 1 of the present invention will be described. Figure 4 It is a partially exploded perspective view showing the relay 31 according to Embodiment 1 of the present invention. Figure 5 is a sectional view of the relay 31 . Figure 6A It is a perspective view showing the optical pattern provided on the inner surface of the case 34 b of the relay 31 . Figure 6B It is the figure (photograph) which looked at the upper surface of the case 34b of the relay 31 from the oblique direction. Figure 7 as well as Figure 8 It is an explanatory diagram of the action of the relay 31.

[0076] The relay 31 includes a relay main body 32 and an operation display lamp 33 built in a case 34 . The case 34 has a base 34a formed of an opaque resin and a case 34b formed of a transparent resin.

[0077] On the upper surface of the base 34a has Figure 4 as well as Figure 5 Relay body 32 of the shown configuration. Th...

Embodiment approach 2

[0104] Figure 15 It is a schematic sectional view showing the relay 61 according to Embodiment 2 of the invention. In this relay 61 , various optical patterns are provided in the optical pattern area 36 . In the illustrated example, two types of optical patterns 37 and 62 are provided. The optical pattern 37 is similar to the optical pattern 37 described in Embodiment 1, and reflects the light guided in the top plate 40a upward. The optical pattern 62 reflects the light guided in the top plate 40 a to the side obliquely, that is, in a direction having a small angle with respect to the horizontal plane. Both the optical pattern 37 and the optical pattern 62 are, for example, triangular prisms or pyramidal prisms, and the inclination angles of the inclined surfaces are different from each other. Others are the same as in Embodiment 1, so the same components are given the same reference numerals and descriptions thereof are omitted (the same applies to Embodiments after Embod...

Embodiment approach 3

[0107] Figure 17 It is a schematic cross-sectional view showing a relay 71 according to Embodiment 3 of the present invention. In this relay 71, a light guide plate 72 serving as a light guide path is arranged directly under the top plate 40a of the case 34b. The corners of the light guide plate 72 are obliquely cut to form the light incident surface 73 . The operation display lamp 33 is arranged at a position facing the light incident surface 73 . On the lower surface of the light guide plate 72, a plurality of optical patterns 37 are formed in an arc shape centering on the incident position of light on the optical pattern area 36 (refer to Figure 6A ), the optical pattern 37 is in the shape of a prism.

[0108] And, in this relay 71, when the light emitted from the operation display lamp 33 enters the light guide plate 72 from the light incident surface 73, the light entering the light guide plate 72 is reflected by the upper surface and the lower surface of the light g...

Abstract

A relay (31, 61, 71, 81) in which a relay body (32) and a light source (33) are incorporated in a case (34), the light source emitting light in conjunction with operation of the relay body (32), wherein a light guide is provided inside an outer surface of the case (34), the light guide is configured to take in the light emitted from the light source (33), to guide the light to a portion parallel to a top panel (40a) of the case (34), and to spread the light in the portion parallel to the top panel (40a), and an optical pattern (37, 62, 82) is provided in at least one of a top surface and a bottom surface of the portion parallel to the top panel (40a), the optical pattern (37, 62, 82) is configured to output, the light guided in the light guide to the portion parallel to the top panel (40a), to outside the case (34) from a top surface of the top panel (40a).

Description

technical field [0001] The invention relates to a relay. Specifically, the present invention relates to a relay with a surface-emitting action display function. Background technique [0002] Conventional relays are provided with an operation display lamp in order to facilitate the operator to confirm the operation of the relay. Such an operation display lamp is provided at an upper portion in the case of the relay so that the lighting state of the operation display lamp can be easily confirmed visually. [0003] Figure 1A as well as Figure 1B It is a schematic sectional view and a schematic plan view showing a conventional relay 11 having an operation display lamp. In this relay 11 , a relay main body 13 composed of a coil unit, a contact unit, and the like is assembled on the upper surface of a base 12 , and the relay main body 13 is covered by a transparent case 14 attached to the base 12 . In the upper part of the transparent case 14, an operation display lamp 15 ma...
