Description
Technical field
The utility model relates to a kind of instrument and meter backlight, the backlight that especially a kind of electric energy meter is used.
Background technology
In existing single-phase electric energy meter, the backlight of LCD liquid crystal comprises a sheet light guide plate that is fixed on support front, LED luminescence component is housed in the notch of light guide plate one end, and the edge that reflectance coating, light guide plate surrounding are posted in the back side of light guide plate posts reflection edge strip with reflection ray.After LED luminescence component electrified light emitting, light, through the reflection of reflectance coating and reflection edge strip, conducts to the front of light guide plate, makes the front of light guide plate luminous, thereby provides demonstration backlight for electric energy meter LCD liquid crystal.
As shown in Figure 6, in above-mentioned backlight, light guide plate A1 and support A2 are two independently parts, need to make respectively.The structure of its medium-height trestle as shown in Figure 7, the back side of support is shaped with one group of angle (being called again support) A3, front is a plane, the periphery of this plane is crowded around and is formed an installation reflection cavity A5 who matches with light guide plate profile by some frame A8, the degree of depth of reflection cavity and the thickness fit of light guide plate (light guide plate sinks to and is fixed in this installation reflection cavity) are installed, the both sides of support respectively offer row's aperture A7 and pass through for the leg of the LCD liquid crystal in light guide plate front, wherein a side is also shaped with the erecting frame A4 of bar shaped, on erecting frame, be shaped with several mount pad A6 for installing electronic elements.The structure of above-mentioned support is comparatively complicated, so manufacture cumbersome, cost is also large, when installation, need again labor intensive adhesive glue that light guide plate is fixed on support, operate comparatively loaded down with trivial details, production efficiency is not high, and exists that cohesive force is strong, light guide plate and the easily defect of disengagement of support, affects the quality of product.
Utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes above-mentioned background technology, and a kind of backlight is provided, that this backlight has is simple in structure, manufacture and easy for installation, production efficiency is high, lower-cost feature.
For realizing above object, the technical solution adopted in the utility model is:
The integrated backlight of electric energy meter, comprise light guide plate, LED luminescence component is housed in the notch of light guide plate one end, reflectance coating is posted at the back side of light guide plate, the edge of light guide plate surrounding posts reflection edge strip, it is characterized in that: the front of described light guide plate is shaped with one group of location stop, region and size that this group location stop surrounds are mated with LCD liquid crystal phase; The back side of light guide plate is fixed with one group of angle, and at least one side of light guide plate is along being fixed with an erecting frame, and described location stop, angle and erecting frame and light guide plate are one-body molded.
Described light guide plate, angle and erecting frame all use transparent PC to make.
Described erecting frame is bar shaped, is shaped with several mount pads for installing electronic elements on erecting frame; Between erecting frame and the edge of light guide plate, keep certain distance to form one and be beneficial to the groove that LCD liquid crystal leg passes through, the two ends of erecting frame are connected with light guide plate.
The back side of described angle and light guide plate is arranged vertically.
The quantity of described angle is four, is distributed in four jiaos of the back side of light guide plate.
The beneficial effects of the utility model are: the utility model is by one-body molded to light guide plate, angle and erecting frame, utilize angle and erecting frame to realize the cradling function of conventional backlight, without first making respectively light guide plate and support, carry out again the bonding work of light guide plate and support by adhesive glue, one-piece construction is simple, manufacture and installation steps are all simplified and facility, work efficiency is improved, cost is lower.

Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As Figure 1-Figure 5, the integrated backlight of electric energy meter described in the utility model, comprises light guide plate 1, in the notch 7 of light guide plate one end, LED luminescence component 8 is housed.The front of light guide plate is shaped with one group of location stop 1-2 (in Fig. 2 be four, two linearly, two rectangular shapes), and mate with LCD liquid crystal phase the rectangular area that this group location stop surrounds, and LCD liquid crystal is fixed in this panel region; The back side of light guide plate is shaped with site and posts reflectance coating, and the edge of light guide plate surrounding posts reflection edge strip, and the front of light guide plate is posted black and white glue 5 (being shadow shield) in one end of close notch and spilt to reduce light.Above structure of the present utility model is all comparatively similar with existing backlight, and its assembling process does not describe in detail at this, reflects edge strip and reflectance coating is also omitted in figure.
In order to reduce number of assembling steps, in the utility model, the back side of described light guide plate is fixed with one group of angle 6, at least one side of light guide plate is along being fixed with an erecting frame 4, and described location stop, angle and erecting frame and light guide plate adopt transparent PC (polycarbonate) integrated injection molding.
The quantity of described angle is generally four, is distributed in four jiaos of the back side of light guide plate, and the back side of angle and light guide plate is arranged vertically.Described erecting frame is bar shaped, and the tabular that described erecting frame is elongated is generally positioned at the wherein longer edge of light guide plate, roughly stretches in the same way with light guide plate.On erecting frame, be shaped with several for example, mount pads 2 for installing electronic elements (diode), mount pad offers the jack 2-1 of the pin of electronic component; Between erecting frame and the edge of light guide plate, keeping certain distance to form one is beneficial to the groove 3 that LCD liquid crystal leg passes through (edge of light guide plate is shaped with recess 1-1, become a part for groove), this groove passes through for the leg of the LCD liquid crystal in light guide plate front, and the two ends of erecting frame are connected with the back side of light guide plate by the connection billet 4-1 crossing out.
