Description

Splitter baffler structure

The utility model relates to a kind of splitter baffler structure, relate in particular to a kind of can be with unnecessary electrostatic charge conducting on the splitter to its housing, thereby reach the baffler structure of ground connection purpose.

(the Community Antenna Television Service of cable television network system, CATV) be to utilize coaxial cable to receive or the network system of TV transmission signal, because the cable television network system is the mode with one-to-many, connected system merchant and user, and be long-distance transmissions, except needs utilize coaxial cable, need use amplifier (Amplifier), splitter (Multi Tap patchplug), power inserter equipment such as (Power Inserter), and finish the process of TV transmission signal to user side, hence one can see that, the equipment that each is connected with coaxial cable, all might influence the quality of transmission signal, thereby influence the rating quality of user side, therefore all must be noted and paid attention to.

Wherein above-mentioned splitter is called directional coupler or distributor again, is a kind of in order to the various signal branches that main signal transmission line carried are delivered to the device of each user side.Please refer to Fig. 1, on the printed circuit board (PCB) 30 of known splitter, except being fitted with many big and small electronic components, in addition in the appropriate location of printed circuit board (PCB) 30, setting has a sheet of baffler body 10, and making electronic component on the printed circuit board (PCB) be separated is two parts, and the material of this baffler body 10 is a kind of metallic conductor, the purpose of so setting up is: utilize the screen effect of metallic conductor itself, and the electromagnetic interference phenomenon between the different electronic components of avoiding desiring to separate.

But, an a fly in the ointment is arranged: do not consider splitter is left in the electrostatic charge guiding, just do not consider the problem of ground connection in the above-mentioned design.Therefore, if build up a large amount of electrostatic charges on splitter, this is a kind of potential injury for the electronic component in the splitter, also is a kind of potential danger for the maintenance personal that meeting touches splitter.

The purpose of this utility model is to propose a kind of splitter baffler structure that is made of the metal baffler of band fin, it can guide to electrostatic charge the housing of metal material effectively, can remove the potential impact of electrostatic charge thus, thereby solve the existing in prior technology problem electronic component.

The technical scheme that the utility model adopted is: the body of conventional baffler is the place's shape conductor that is erected on the printed circuit board (PCB) of splitter, make on this printed circuit board (PCB) electronic component thereby be divided into two zones, in order to produce the phenomenon of electromagnetic interference between the electronic component of avoiding this two zone, it is characterized in that:

At the end of this baffler body, have the fin of at least one metal material, contact with the housing of this splitter by this fin, with as media the electrostatic charge ground connection on this baffler body.

Advantage of the present utility model is that it can avoid electrostatic charge to build up and influence circuit and personnel's safety in splitter.

Fig. 1 is the schematic diagram of conventional splitter baffler structure;

Fig. 2 is the first embodiment schematic diagram of the utility model splitter baffler structure;

Fig. 3 is the second embodiment schematic diagram of the utility model splitter baffler structure; And

Fig. 4 is the 3rd an embodiment schematic diagram of the strong structure of the utility model splitter baffler.

Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now.Please refer to Fig. 2, it is the structural representation of first embodiment of the present utility model, show among the figure, the utility model is to utilize on the printed circuit board (PCB) 30 of conventional splitter, had a baffler body 10 in order to the metal material of avoiding electromagnetic interference, therefore as long as on baffler body 10, increase at least one

fin

21,22, as the media of contact baffler body 10 with the metal shell 35 of splitter, can reach the purpose of the unnecessary electric charge of guiding, and then reach the effect of ground connection via housing 35 to housing 35.

Enforcement state as for above-mentioned

fin

21,22, as shown in Figure 2, the utility model is two ends in baffler body 10, increases by one first wall 11 and one second wall 12 respectively, and this two

wall

11,12 can be bent about 90 degree by the end of baffler body 10 and form; And then in the upper end of first wall 11 and second wall 12, connecting one first fin 21 and second fin, 22, two

fins

21,22 respectively can outwards be bent to form the structure of similar shell fragment again by two walls, 11,12 integrally formed extending out.Therefore, when the housing 35 of splitter is covered on the printed circuit board (PCB) 30, contacts the path that is caused by first fin 21, second fin 22 with housing 35, and unnecessary electrostatic charge is guided to housing 35, and then reach the purpose of ground connection via housing 35.

In addition, the utility model increases by a jog 13 on the baffler body 10 of conventional sheet, by offering a groove (seeing it by another side is a projection) in the plane, and strengthens the ability that baffler body 10 bears strength, makes it more not yielding.

Please refer to Fig. 3, it is the structural representation of second embodiment of the present utility model, show among the figure, the utility model also can bend first wall 11 towards different directions with second wall 12, as long as first fin 21 and second fin 22 still are all the shell fragment pattern that outside bending is extended, and the contacting of maintenance and housing 35, just can not influence the effect of guiding electrostatic charge of the present utility model.

Please refer to Fig. 4, it is the structural representation of the 3rd embodiment of the present utility model.In fact, if to reach contact the guiding function of electric charge and opinion, as long as cause and 35 of housings have a contact point at least; Therefore, but the utility model is the structure of reduced graph 2 or Fig. 3 also, only the end at baffler body 10 is provided with a wall 11 and a fin 21, as long as definite fin 21 can keep and the contacting of housing 35, then what difference is the effect of its conducting electrostatic charge just just do not had with first and second enforcement.

The utility model is to utilize on the printed circuit board (PCB) of conventional splitter, set up the baffler of a metal material, therefore increase the fin of a metal material at least at two ends of baffler, it is contacted with the housing that is all conductor, thereby guide unnecessary electrostatic charge to housing, reach the purpose of ground connection again via housing; Therefore, can avoid the inside of electric charge accumulation, and cause the damage of electronic component, or become the potential hazard that the maintenance personal gets an electric shock in splitter.

Though the utility model discloses as above with several preferred embodiments; right its is not in order to limit the utility model; any those skilled in the art; in the scope that does not break away from spirit of the present utility model; change and retouching when doing some, therefore protection range of the present utility model when look the accompanying Claim book protection range defined is as the criterion.
