Abstract
The utility model relates to a pressing device for an internal circuit of a computer keyboard. The folding surface of a circuit board and a flexible circuit board is pressed with a flexible rubber sheet of which both sides are respectively provided with a through hole; the bottom surface of a bottom case is provided with a groove corresponding to the flexible rubber sheet; both sides of the groove are also respectively provided with a through hole corresponding to the through holes of the flexible rubber sheet. Both sides of a metal strip plugged in the groove are respectively provided with a through hole corresponding to the through holes of the groove. Two screws are respectively penetrated and locked in the through holes at both sides of the metal strip, the groove of the bottom case, the flexible rubber sheet and a top shell. The utility model avoids bad contact situations via average pressing force provided by the soft rubber sheet and via the mode that the strength of the computer keyboard is enhanced through press by the metal strip.
Description
The utility model relates to a kind of computor-keyboard internal circuit press fit device, especially refer to that a kind of nationality is pressed on by a soft film that soft circuit is pulled and the circuit face of circuit board on so that average contact area to be provided, nationality is clamped so that soft circuit board and circuit board and soft film clamp, with the computor-keyboard internal circuit press fit device of preventing poor contact situation generation by bonding jumper again.
The computor-keyboard of generally commonly using, its upper limb in upper shell is installed a circuit board earlier, from bottom to top installing several flexible members, flexible circuit board and lower house more in regular turn forms, and circuit board arrangement is in lower house top one side, and the circuit face of circuit board again with corresponding flexible circuit board on the circuit face conducting that is superimposed; Yet the circuit face of circuit board and flexible circuit board keeps compressing the mode of contact conducting, corresponding to circuit board and each sealed screw of both sides, the superimposed place of flexible circuit board circuit face, so nationality is clamped to provide circuit board and flexible circuit board clamping strength closely by housing in upper shell and lower house both sides.
Yet the mode of above-mentioned employing, because of upper shell and the used material softer (being generally plastic cement) of lower house, when folding, upper shell and lower house turn red easily because of insufficient strength, so can't reach clamping purpose closely fully, computor-keyboard artificial carelessness of combination personnel when assembling again, when itself making tolerance issues and the problems such as detritus that might produce during screw closure, all might influence, lower house is to the circuit face of circuit board and flexible circuit board superimposed place clamping state closely, thereby produces between the contact circuit plate gapped and situation that produce loose contact takes place.
Fundamental purpose of the present utility model, aim to provide a kind of computor-keyboard internal circuit press fit device, the superimposed place of its circuit face in circuit board and flexible circuit board presses puts a soft film, in the drain pan bottom recesses, insert a bonding jumper again, it is sealed to penetrate the groove of bonding jumper, drain pan, soft film and top shell respectively via screw again, the strength of the circuit face tight pressing in superimposed place of circuit board and flexible circuit board so can be provided, and strengthen the intensity of lower house when sealed by bonding jumper, and the state that reaches true Pingdu takes place with the situation of avoiding two circuit face loose contacts.
The purpose of this utility model is achieved in that a kind of computor-keyboard internal circuit press fit device, wherein install a circuit board in the inner upper limb of top shell, from bottom to top installing a flexible member, flexible circuit board and drain pan more in regular turn constitutes, the conducting and the circuit face of the circuit face of this circuit board and flexible circuit board one side is superimposed, press on circuit board and the flexible circuit board superposed surfaces and establish a soft film, respectively establish a perforation in soft film both sides again; Corresponding to soft film one groove is set in the drain pan bottom surface in addition, these groove both sides are also established a perforation and are bored a hole corresponding to soft film, insert in groove again that a perforation is respectively established in a bonding jumper and its both sides and corresponding to the perforation of groove, it is sealed to penetrate the groove of bonding jumper, drain pan, soft adhesive tape and top shell two side perforations respectively by two-screw again.
Bonding jumper can directly be pressed on the soft film, is penetrated respectively with bonding jumper, soft adhesive tape and top shell by drain pan by screw to lock together again.
When using according to above-mentioned structure, the utility model nationality provides average pressure force by the retractility of soft film, again by the intensity of bonding jumper pressing with the enhancing computor-keyboard, so takes place with the situation of avoiding loose contact.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is a sectional perspective exploded view of the present utility model.
Fig. 2 is a section constitutional diagram of the present utility model.
Fig. 3 is another enforcement illustration of utility model.
At first, please earlier referring to Figure 1 and Figure 2, the utility model is installed a circuit board 2 by top shell 1 inner upper limb, from bottom to top installing several flexible members 3, a flexible circuit board 4 and drain pan 5 more in regular turn constitutes, and the conducting that is superimposed of the circuit face 41 of the circuit face 21 of this circuit board 2 and flexible circuit board 4 one sides, flexible circuit board 4 is pulled to press on 2 superposed surfaces with circuit and is established a soft film 6, respectively establishes a perforation 61 again in soft film 6 both sides; Corresponding to soft film 6 groove 51 is set in drain pan 5 bottom surfaces in addition, a perforation 511 is also established and corresponding to the perforation 61 of soft film 6 in these groove 51 both sides, insert in groove 51 again that a perforation 71 is respectively established in a bonding jumper 7 and its both sides and corresponding to the perforation 511 of groove 51, penetrate the perforation 71,511,61 of both sides on the groove 51, soft adhesive tape 6 of bonding jumper 7, drain pan 5 more respectively by two-screw 8, and the protruding tube 11 of top shell 1 inside is sealed;
Of the present utility model another implemented illustration (as shown in Figure 3), bonding jumper 7 of the present utility model can directly be pressed on the soft film 6, penetrate respectively by drain pan 5 by two-screw 4 again and lock together, so that the identical tight effect of pressing to be provided with bonding jumper 7, soft film 6 and drain pan 5.
When using according to above-mentioned structure, soft film 6 tool retractilities of the present utility model and can on average being pressed on the circuit face superposed surfaces of flexible circuit board 4 and circuit board 2, and increase the intensity of computor-keyboard drain pan 5 by the sealed of bonding jumper 7, and the effect that can obtain preferable true plane takes place with the situation of avoiding loose contact.
The utility model nationality is average pressing circuit board superposed surfaces by the contractility of soft film 6, and bonding jumper 7 strengthens the intensity of computor-keyboard housing to obtain true plane effect, and then it is avoid commonly using computor-keyboard, and above-mentioned because of the untight situation generation of personal error, tolerance and driving fit that external factor causes because of the not enough shortcoming of driving fit fully of Material Strength.
