Technical field
The utility model relates to a kind of mobile net card housing.
Background technology
Mobile net card is the critical component that is used to carry out the network connection of wireless communication field.Existing commercially available mobile net card by up and down two form.For example, notification number is to have proposed a kind of novel casing structure of mobile net card in the Chinese utility model of CN 2874985, comprise a plastic frame body, the network interface card substrate, last metal cover board and following metal cover board and about Metallic rod respectively, wherein, last metal cover board and following metal cover board cover up and down with plastic frame body on, allow the little edging of a plurality of bendings in both sides of metal decking insert respectively in corresponding on the plastic frame body " protruding " shape hole, two Metallic rod are inserted the space that is formed by upper and lower panel edging and plastic frame body inboard groove from plastic frame body the place ahead circular hole, utilize the elastic force of edging that plastic frame body and metal decking are combined, simultaneously, last metal decking, the staggered edging of following metal decking is blocked by Metallic rod total is combined into one.
But this shell structure of existing mobile net card can be dismantled in repeated combination, and still, electrostatic problem between metal cover board is more up and down for it, and production cost is higher.
Summary of the invention
The technical problem to be solved in the present invention provides the shell structure of the less mobile net card of a kind of electrostatic problem.At above-mentioned problem, the utility model provides a kind of mobile net card housing, comprises panel and the framework that is used for installing in advance the network interface card substrate, it is characterized in that described panel is the single integral piece structure, constitutes the cavity of the opening of holding described framework.Fundamentally solved the electrostatic conducting problem of two-piece type structure thus, and can reduce the part number, enhance productivity and reduce production cost.
Preferably, metal decking is formed by the bending of a slice sheet metal, but obviously also can pass through the moulding of other materials processing method.
According to an aspect of the present utility model, at least one inboard of panel two edges of the relative connection of the side direction abutting end of panel in other words is provided with at least one first edging that constitutes because of bending, and these first edgings fit together mutually.The frame relative with the side direction abutting end outside of plastic frame body offers groove, and first edging that fits together is contained in the groove on the plastic cement frame.Thereby when the plastic frame body that the network interface card substrate is installed in advance was pushed in the cavity that described metal decking constitutes, first edging that fits together was contained in the groove, and plastic frame body is led.
Preferably, plastic frame body is the U type, and the inboard of the blind end of U type framework is provided with at least one locking buckle as the stopper section.Described locking buckle is the projection of stretching out to the inside that is arranged on the blind end of U type framework.Preferred locking buckle and described U type framework are integrally formed.Correspondingly, the cavity that metal decking constitutes is formed with second edging that constitutes because of bending at an open end, and the locking buckle may be locked in this second edging.
When being used in combination, one network interface card substrate is installed in plastic frame body earlier, the plastic frame body that will have the network interface card substrate then is pushed in the cavity of metal decking formation, metal decking edging and plastic frame body outside groove match and lead, when the blind end of U shape glue framework enters in the cavity that metal decking constitutes at last, utilize locking buckle that the inboard of the blind end of U shape glue framework is provided with to lock mutually, thereby plastic frame body is locked in the cavity of metal decking formation with second edging of an end that is arranged on the cavity that metal decking constitutes.
Advantage of the present utility model is: combined and instant is simple, and dismounting repeats mounting or dismounting and also can not cause damage parts easily; Sheet metal from up and down two reduce to and have only a slice, can fundamentally solve the problem of static conduction, prevent that electromagnetic radiation from revealing, reach shield effectiveness.

Embodiment
Now in conjunction with the accompanying drawings the utility model embodiment is described below:
Fig. 1 is the stereogram of mobile net card housing of the present utility model after assembling.As can be seen from the figure, plastic frame body 2 is contained in the cavity of metal decking 1 formation, also accommodates network interface card substrate 3 in the plastic frame body 2.
Fig. 2 is an exploded view of the present utility model.As can be seen from Figure 2, the mobile net card housing comprises a metal decking 1 and plastic frame body 2, and network interface card substrate 3 can be contained in the plastic frame body 2 in advance.Network interface card substrate 3 is provided with the electronic devices and components of realizing the network interface card function.Plastic frame body 2 is bearing parts, and the cavity that metal decking 1 constitutes is mainly used in realizes good screen effect.
As can be seen from Figure 2, this metal decking 1 forms by a slice metal being carried out bending, thereby constitutes an open cavity that holds plastic frame body 2, certainly, also can form open cavity by other molding modes.Plastic frame body 2 can be inserted into this cavity from an end 10 (can certainly be the other end 10 ') of this opening cavity.At least one inboard of the cavity that metal decking 1 constitutes is provided with at least one first edging 11 and 12 that constitutes because of bending, and these little edgings are that metal decking 1 forms in the bending process.First edging 11 and 12 matches with the groove 21 (as shown in Figure 3) of plastic frame body 2.The open end 10 of the cavity that described metal decking 1 constitutes is formed with second edging 13 that constitutes because of bending.At least one locking buckle 22 that second edging 13 is used for being provided with the inboard of the blind end of plastic cement frame is corresponding.
Described plastic frame body 2 is the U type, offers groove 21 (shown in 3,4) in its frame outside, stretches out at least one locking buckle 22 at an end of the closure of U shape glue framework 2.The locking buckle is the projection of stretching out to the inside that is arranged on the blind end of U type framework.Certainly, buckle can be integrally formed with U shape glue framework.
With reference to Fig. 3,4,5, metal decking 1 bending and molding is that the little edging 11 and 12 that forms in the process of cavity fits together, and is contained in the groove 21 on the plastic frame body.Edging 13 is corresponding with plastic cement frame buckle 22, realizes locking (as shown in Figure 5).When being used in combination, a network interface card substrate 3 is installed in plastic cement frame 2 earlier, the assembly with plastic cement frame and network interface card substrate inserts in the metal decking then, and the groove 21 in the glue framework 2 one side frames outside is matched with the little edging 11 and 12 of metal decking bending; Plastic cement frame buckle 22 stretched in the metal decking and cooperates with edging 13 after combination put in place.After at least one locking buckle 22 that only inboard of plastic cement frame blind end need be provided with during dismounting is deviate from, just can directly unload metal decking.
