Abstract
The utility model provides an antistatic liquid crystal metal cover and relates to a liquid crystal metal cover. The antistatic liquid crystal metal cover can be used for solving the problems that an existing liquid crystal metal cover is needed to be additionally provided with a conductive adhesive strip for cooperative use, so the cost is increased, and the assembly process is complex; and when the existing liquid crystal metal cover and the conductive adhesive strip are not in cooperative use, the metal cover and a main control board cannot be fixedly and firmly combined, a liquid crystal screen is subjected to display abnormality or looseness when being pressed, and static electricity cannot be reliably shielded, so the liquid crystal screen is damaged by the static electricity. A metal shell is a bottomless rectangular box-shaped shell and is provided with a liquid crystal screen window; two side surfaces in the width direction of the metal shell are respectively and symmetrically provided with multiple liquid crystal bracket clamping slots; two spacing platforms are respectively arranged at the middle parts of two lateral edges in the width direction of the metal shell; buckle lugs are arranged at two ends of each spacing platform and fixedly arranged on the metal shell; and the metal shell, the spacing platforms and the buckle lugs are integrally manufactured. The antistatic liquid crystal metal cover is used for protecting the liquid crystal screen from being damaged by static electricity.
Description
Technical field
The utility model relates to a kind of liquid crystal metal cap, is specifically related to a kind of antistatic liquid crystal metal cap.
Background technology
General liquid crystal metal cap need increase conductive adhesive tape and be used, and increases cost, the assembly technology complexity.As not increasing conductive adhesive tape; not only can not guarantee fixation between the combination of metal cap and master control borad, thereby cause the liquid crystal display display abnormality or loosening that is stressed, but also can not guarantee metal cap 100% effective grounding; can't reliably shield static, can not effectively protect liquid crystal display to avoid electrostatic damage.
To sum up, there is following problem in existing liquid crystal metal cap:
1. existing metal cap need increase conductive adhesive tape and is used, and has not only increased the fringe cost when metal cap uses, waste fund, and assembly technology complexity.
2. when existing metal cap is not used with conductive adhesive tape, then display abnormality or loosening can be able to not be appearred in metal cap and master control borad combination fixation when causing the liquid crystal display pressurized.
3. existing metal cap can not guarantee 100% effective grounding, can't reliably shield static, causes liquid crystal display to be subjected to electrostatic damage.
The utility model content
The purpose of this utility model is to exist 1. to need the increase conductive adhesive tape to be used in order to solve existing liquid crystal metal cap, has not only increased the fringe cost when metal cap uses, waste fund, and assembly technology complexity; 2. when existing metal cap is not used with conductive adhesive tape, then display abnormality or loosening can be able to not be appearred in metal cap and master control borad combination fixation when causing the liquid crystal display pressurized; 3. existing metal cap can not guarantee 100% effective grounding, can't reliably shield static, causes liquid crystal display to be subjected to the problem of electrostatic damage, and then a kind of antistatic liquid crystal metal cap is provided.
The technical solution of the utility model is: a kind of antistatic liquid crystal metal cap, it comprises metal shell, two limiting stands and four button pin, described metal shell is no bottom surface rectangular box shape housing, have the liquid crystal display window on the metal shell, two sides on metal shell Width symmetry respectively have a plurality of liquid crystal bracket clamp access slots, two limiting stands are located at two lateral edge middle parts on the metal shell Width respectively, described button pin is located at the two ends of limiting stand and is packed on the metal shell, described metal cap, limiting stand and button pin are made one
Described button pin comprises the spacing button pin of level, brace, vertical spacing pin and the restriction protrusion of buckleing, the spacing button pin of level, brace and the vertical spacing pin of buckleing are connected from the inside to the outside successively, restriction protrusion and brace are located on the vertical spacing same side end face of buckleing pin, the spacing button pin of level, brace, vertically spacingly buckle pin and restriction protrusion at grade and make one.
The utility model compared with prior art has following effect:
1. the utility model need not increase conductive adhesive tape and is used, and not only reduced the fringe cost when metal cap uses, and assembly technology is simple.
2. the utility model is by the brace of turn buckle pin; make interference fit between button pin and master control borad; the relative master control borad of button pin has produced two surface of contact that interlace; can fix spacing to the master control borad combination; thereby effectively protect liquid crystal display to avoid vibrations and pressure influence, avoid liquid crystal display display abnormality or loosening to occur because being subjected to external force.
3. the utility model makes all effectively contacts simultaneously of the double-edged ground plane of master control borad by the turn buckle pin, metal cap 100% effective grounding, thus effectively shielding static, the protection liquid crystal display is avoided electrostatic damage.
4. the utility model adopts stamped technology to make, and this manufacturing technology mature and reliable guarantees that the metal cap size is accurate, dependable performance, enhances productivity simultaneously.
