The shielding extension tail end bottom that presss from both sides both ends be equipped with the recess, when the installation is fixed, through filling soldering tin to the recess, strengthen the fastness of the shielding holder body and circuit joining of plates, additionally do not need to guarantee the welded fastness through the bonding area who increases the shielding holder body and circuit board.
Description
Technical field
The utility model relates to mechanical field, specifically, is that a kind of EMI soldering structure strengthens shield clip.
Background technology
As everyone knows, all electronic products all can produce electromagnetic interference (ElectromagneticInterference in operation, EMI) problem, even and if electromagnetic interference electronic product itself energising after, circuit board in electronic equipment, wire and electronic component etc. operationally often can send the electromagnetic wave of high frequency, the electromagnetic wave produced because of electromagnetic induction effect to arround the interference effect that causes of electronic equipment, also because electromagnetic interference can cause other electric equipment operating interruptions, abnormal shutdown, safeguard and increase, crosstalk and system delay, also may produce harm to human body simultaneously.
In order to reduce electromagnetic interference machine radiation hazradial bundle, in electronic equipment, often adopt electro-magnetic shielding cover by covers such as circuit board, wire and electronic components in the inner, to reach the electromagnetic object of shielding.But existing electro-magnetic shielding cover is mostly whole ironware punching press formation, it is soldered to cover the electronic component of shielding on circuit board, thus plays shielding action.But when the circuit board under the electronic component be shielded from this electro-magnetic shielding cover or this electro-magnetic shielding cover needs to keep in repair, electro-magnetic shielding cover is needed to disassemble completely, needing to add larger active force to electro-magnetic shielding cover and circuit board in unloading process makes the two mutually depart from, then disassemble completely in operation, the active force applied on circuit boards is easy to cause damage to the structure of circuit board in operation.Therefore, a kind of for solving EMI electro-magnetic shielding cover and circuit board fixation problem, facilitate again the clamping device of engineering staff's operating maintenance just can better meet the Production requirement of electronic applications simultaneously.
Utility model content
Utility model object: the purpose of this utility model is for weak point of the prior art and provides the shield clip that a kind of EMI soldering structure strengthens, by filling scolding tin in the groove of shield clip, strengthen the fastness of the base of shield clip and the connection of circuit board further.
Technical scheme: for achieving the above object, a kind of EMI soldering structure described in the utility model strengthens shield clip, comprise: a pedestal, a location division is provided with in the middle of described pedestal, both sides, institute location division are respectively equipped with extension, described extension both sides are respectively equipped with holding shrapnel, are provided with a groove bottom the tail end of described extension.
Further, the two panels holding shrapnel of described extension both sides is oppositely arranged, and two panels holding shrapnel is identical relative to the height of extension.
Further, the top of described holding shrapnel is an outer portion, and being lug boss below a described outer portion, is belly below described lug boss.
Further, the height of the mid portion of described location division and extension is a little more than marginal portion.
Further, described location division and extension junction are each side provided with a breach.
Compared with prior art, the beneficial effects of the utility model are:
1, a kind of EMI soldering structure described in the utility model strengthens shield clip, groove is provided with bottom the extension tail end at shield clip two ends, when installing fixing, by filling scolding tin to groove, strengthening the fastness of the connection of shield clip pedestal and circuit board, not needing additionally by strengthening the fastness that shield clip pedestal and the bonding area of circuit board ensure to weld.
2, a kind of EMI soldering structure described in the utility model strengthens shield clip, groove design makes the solder thickness between shield clip pedestal bottom margin and circuit board diminish, efficiently solve the gap problem existed when radome and circuit board are fixed, the electromagnetic wave avoiding electromagnetic induction effect to produce through gap to arround electronic equipment cause interference.

Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
A kind of EMI soldering structure as shown in Figure 1-2 strengthens shield clip, comprise a pedestal 1, a location division 11 is provided with in the middle of described pedestal 1, both sides, institute location division 11 are respectively equipped with extension 12, described extension 12 both sides are respectively equipped with holding shrapnel 13, are provided with a groove 14 bottom the tail end of described extension 12.
Particularly, the two panels holding shrapnel 13 of described extension 12 both sides is oppositely arranged, and two panels holding shrapnel 13 is identical relative to the height of extension 12.
Particularly, the top of described holding shrapnel 13 is an outer portion 131, and being lug boss 132 below a described outer portion 131, is belly 133 below described lug boss 132.
Particularly, the height of the mid portion of described location division 11 and extension 12 is a little more than marginal portion.
Particularly, described location division 11 is each side provided with a breach with the junction of extension 12.
In the present embodiment, a kind of EMI soldering structure strengthens shield clip, is clamped the sidewall 31 of the surrounding of electro-magnetic shielding cover 3 by two holding shrapnels 13, and then realizes and circuit board 2 is connected and fixed.As shown in Figure 3-4, when installing fixing, groove 14 bottom the pedestal 1 of shield clip is filled scolding tin, whole shield clip pedestal 1 is first welded on the circuit board 2, outer portion 131 of holding shrapnel 13, lug boss 131 and belly 133 three form an elastic space, during use, the sidewall 31 of electro-magnetic shielding cover 3 is vertically inserted holding shrapnel 13 and be fixed.When needs check maintenance to electronic building brick, only electro-magnetic shielding cover 3 upwards need be taken out from holding shrapnel 1, damage can not be caused to the electronic devices and components of surrounding and circuit board 2.As shown in Figure 5 electro-magnetic shielding cover 3 fixing with circuit board 2 after state, four shield clips clamp the sidewall 31 of electro-magnetic shielding cover 3 respectively, do not need additionally by strengthening the fastness that shield clip pedestal 1 and the bonding area of circuit board 2 ensure to weld.
