Abstract

The utility model provides a plasma module backboard getting rid of a rivet mounting mode, which is provided with a backboard main body, wherein the backboard main body is integrally provided with a plurality of protrusion parts for fixing and supporting PCB circuit boards in a forming mode. Preferably, the protrusion parts are lug bosses formed by stamping; the tops of the protrusion parts are provided with thickened connecting parts; and threaded holes are formed in the center of the connecting parts and extend and pass through the connecting parts. The plasma module backboard does not adopt riveted studs, thereby omitting production links of the riveted studs, simplifying production procedures, improving the production efficiency, saving raw materials, further reducing the production cost and having considerable economic benefit.

Description

Plasma module backboard

Technical field

The utility model relates to the plasma display field, and more specifically, relates to the backboard of plasma module.

Background technology

The glass screen of plasma display (Plasma Display Panel, be called for short PDP) generally is adhesively fixed on the metal backing with the heat radiation adhesive tape, and distribution is provided with self-clinching standoff that the numerous height of number do not wait to be used for fixing and to support the PCB wiring board on the backboard simultaneously.

In the prior art, adopt self-clinching standoff that the PCB wiring board is assembled on the metal backing, as shown in fig. 1, self-clinching standoff 5 comprises flange part 5a, columnar portion 5b and is formed on threaded hole 5c among the columnar portion 5b, wherein, flange part 5a is positioned in the opening on the backboard 6, and backboard 6 is attached to glass screen 3 by bonding agent 4.By flat head screw 7 PCB wiring board 2 and self-clinching standoff 5 are fixed together, thereby columnar portion 5b is fixed and support wiring board 2.Need plenty of time and manpower in the production run of above-mentioned self-clinching standoff 5, this method is consuming time, consumption power waste material again, especially also need carry out special producing when self-clinching standoff criteria of right and wrong part.Therefore need a kind of plasma module backboard that can overcome above-mentioned shortcoming.

The utility model content

Problem to be solved in the utility model provides a kind of plasma module backboard that can replace the rivet mounting means, reaches the purpose of simplifying production routine and saving material.

For solving the problems of the technologies described above, the utility model provides a kind of plasma module backboard of alternative rivet mounting means, and this backboard has back plate main body, wherein, form a plurality of lug bosses fixing and the support wiring board on back plate main body, wiring board is threadedly connected to lug boss.

Preferably, according to plasma module backboard of the present utility model, wherein, lug boss is the boss that punching press forms, and has the connecting portion of thickening at the top of lug boss, and threaded hole is formed at the central position of connecting portion and extends through connecting portion.

Preferably, according to plasma module backboard of the present utility model, wherein, lug boss is truncated cone-shaped or terrace with edge.

Preferably, according to plasma module backboard of the present utility model, wherein, plasma module backboard is formed by the sheet material that thickness is at least 1.5mm.

The utlity model has following technique effect:

Be useful on boss structure fixing and support PCB wiring board according to forming on the plasma module backboard of the present utility model, need not to adopt self-clinching standoff, thereby saved the production link of self-clinching standoff, simplified production routine, improve production efficiency and saved starting material, therefore reduce production cost, had considerable economic.

Should be appreciated that above generality is described and the following detailed description is all enumerated and illustrative, purpose is in order to provide further instruction to claimed the utility model.

Description of drawings

Accompanying drawing constitutes the part of this instructions, is used to help further understand the utility model.These accompanying drawings illustrate a preferred embodiment of the present utility model, and are used for illustrating principle of the present utility model with instructions.Identical in the accompanying drawings parts are represented with identical label.Wherein:

Fig. 1,2 shows the assembling synoptic diagram of the backboard of traditional employing self-clinching standoff;

Fig. 3 shows the partial view according to the plasma module backboard of a preferred embodiment of the present utility model; And

Fig. 4 shows the part assembling synoptic diagram according to the plasma module backboard of a preferred embodiment of the present utility model.

Embodiment

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.It should be noted that hereinafter only the utility model feature unlike the prior art to be described,, just do not given unnecessary details here for the technical characterictic that can find in the prior art.

With reference to shown in Figure 3, be the partial view of the plasma module backboard of a preferred embodiment of the present utility model.Have a plurality of boss (lug boss) 1 integrally formed on this plasma module backboard with back plate main body 3, particularly, these boss are preferably truncated cone-shaped (also can form terrace with edge shape in other cases), the top of boss 1 has the connecting portion 1a of thickening, central position at connecting portion 1a is formed with a threaded hole 1b, and this threaded hole (direction shown in Fig. 3) from top to bottom extends through connecting portion 1a.

Particularly, the boss on this plasma module backboard 1 is made by punching press.Backboard is selected for use and is not less than the thick sheet material formation of 1.5mm, the position of self-clinching standoff is set at needs, height according to required self-clinching standoff designs staking punch on punch die, after carrying out punching press, carry out tapping on the boss 1 and then form threaded hole 1b going out, such boss 1 fixes with regard to alternative original self-clinching standoff and supports the PCB wiring board.Be understandable that, when punching press, can form the connecting portion 1a of thickening because of the backboard metal material is stamped to extend.It should be noted that the boss on the module backboard of the present utility model also can process by other modes that is fit to, for example casting, the boss that form this moment can be an entity, and then forms threaded hole therein by tapping.

With reference to Fig. 3, show part assembling synoptic diagram according to the plasma module backboard of a preferred embodiment of the present utility model.As can be seen, wiring board 2 and boss 1 can be linked together by flat head screw 4, thereby wiring board 2 is fixed on the back plate main body 3.Therefore adopt according to plasma module backboard of the present utility model, can substitute traditional rivet mode, reach the purpose of simplifying production routine and saving material.

The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
