Embodiment
Consult Fig. 1, be the three-dimensional exploded view of electronic equipment in the embodiment of the present invention 10.Electronic equipment 10 comprises screening arrangement 20 and circuit board 40.
Consult Fig. 2 and Fig. 3, screening arrangement 20 comprises top board 21, two oppose side walls 22, a pair of holding parts 23, location division 24 and a plurality of shell fragment 25.Described sidewall 22 links to each other with top board 21 respectively, and surrounds receiving space 28 jointly.Each holding parts 23 comprises kink 232 and card division 234.Described holding parts 23 roughly is positioned at the centre of a pair of opposing sidewalls 22 respectively, and gapped between the dual-side of described kink 232 and the corresponding sidewall 22, is used to strengthen the elasticity of described card division 234.One end of kink 232 is connected in sidewall 22, and the other end connects card division 234.Card division 234 comprises extension 2342 and grab 2344.Extension 2342 extends towards the direction of circuit board 40 from kink 232.Grab 2344 is extended by extension 2342, is used for screening arrangement 20 is installed in circuit board 40.In the present embodiment, the profile of grab 2344 is isosceles triangle, and its end is provided with rounding, to avoid forming wedge angle and the scratch circuit board.The Breadth Maximum of grab 2344 is bigger than the width of extension 2342.Extend from the edge of one of them sidewall 22 location division 24.Described shell fragment 25 forms to the direction turnover that deviates from receiving space 28 from the end of sidewall 22 respectively.Screening arrangement 20 can be one-body molded by punching press and bending technology.
Simultaneously with reference to Fig. 1 and Fig. 4, circuit board 40 comprises that electronic component 42, a pair of card join hole 44 and location hole 46.Electronic component 42 is arranged at the surface of screening arrangement 20.Card is joined two surfaces that hole 44 and location hole 46 run through circuit board 40 respectively.Card is joined hole 44 and is the T type, and it comprises insertion section 442 and the holding section 444 that communicates with insertion section 442.The width of insertion section 442 is bigger than the width of holding section 444.And two distance between the holding section 444 greater than the distance between two insertion sections 442.The Breadth Maximum of grab 2344 is less than the width of insertion section 442, and greater than the width of holding section 444.Distance between the grab 2344 of two holding parts 23 equals or is slightly larger than two cards to join distances between the holding section 444 in hole 44.Like this, make grab 2344 to pass, and block the edge that card is joined the holding section 444 in hole 44 from the insertion section 442 that card is joined hole 44.
With reference to Fig. 5, during assembling, screening arrangement 20 is installed on the circuit board 40 simultaneously.Electronic component 42 on the circuit board 40 is contained in the receiving space 28 of screening arrangement 20.The card division 234 of holding parts 23 is joined hole 44 with corresponding card and is engaged.The grab 2342 of card division 234 is pressed to the insertion section that card is joined hole 44 by external force, insert card and join the insertion section 442 in hole 44, discharge external force, and pass through the elastic force of the kink 232 of card division 234, grab 2342 card that rebounds is joined the holding section 444 in hole 44, and hook the edge that card is joined the holding section 444 in hole 44.Spacer 24 is contained in the positioning hole corresponding 46, so that screening arrangement 20 is positioned on the circuit board 40.At this moment, the shell fragment 25 of screening arrangement 20 presses in circuit board 40, to reach the effect of electromagnetic shielding.
During dismounting, card division 234 that can be by pressed by external force holding parts 23 make the grab 2344 of card division 23 move to the insertion section 442 that card is joined hole 44, and like this, the card division 234 of holding parts 23 just can be joined the hole 44 from card and shifted out, thereby makes screening arrangement 20 breaking circuit plates 40.So described screening arrangement 20 easy accessibility, the efficient height.
Consult Fig. 6, be depicted as the stereogram of the screening arrangement 30 of another execution mode of the present invention.In the present embodiment, screening arrangement 30 comprises two oppose side walls 32, and its entire length of the end of each sidewall 32 is provided with integral type shell fragment 35.In the present embodiment, described shell fragment 35 is formed by the terminal outwards turnover of each sidewall 32.Wherein the middle part of pair of sidewalls 32 is respectively arranged with a holding parts 33, and the middle part of another sidewall 32 is provided with spacer 34, respectively the shell fragment on it 35 is divided into two parts.Described holding parts 33 is identical with the shape and the structure of aforementioned holding parts 23, is not repeated herein.The sidewall 32 of screening arrangement 30 is inclined design, and more helps shell fragment 35 by the elasticity that angled side walls 32 forms and press circuit board 40, to reach the effect of shielding.
Consult Fig. 7, be depicted as the stereogram of the screening arrangement 50 of the another execution mode of the present invention.In the present embodiment, the two edges of grab 5344 are respectively equipped with flange 5346, form the situation that the knife edge cuts the people with the two edges of avoiding grab 5344.Top board 51 is provided with plural louvre 512, makes described screening arrangement can distribute the heat that produces when electronic component 42 is worked among Fig. 1 effectively.
Though the present invention discloses as above with better embodiment, so it is not in order to limit the present invention.Only, any those who are familiar with this art without departing from the spirit and scope of the present invention, change and retouching when doing, so protection scope of the present invention are as the criterion when looking accompanying the claim person of defining.
