Abstract
The utility model relates to a shielding box, in particular to a cassette box cover shielding box with convenient manufacture and low cost. The shielding box comprises a rectangular box body and a rectangular box cover, wherein, S-shaped bent arcs towards the inner side of the box cover are arranged on the four side edges of the rectangular box cover; gaps are formed at the joints of the four sideedges; and ball bulges for clamping the box cover and avoiding falling are punched on the outer side of the upper opening of the box body and in the position corresponding to the S-shaped bent arcs of the box cover. The utility model has the advantages of simple structure and lower cost, solves the use defects existing in the prior art, greatly facilitates the construction, reduces the processingcost, and enhances the economic benefit.
Description
Technical field
The utility model relates to a kind of shielding box, particularly a kind of easily manufactured, low-cost cassette lid shielding box.
Background technology
For preventing the interference of electromagnetic field of high frequency to circuit, anti-electromagnetic interference is the important composition of high-frequency circuit topology design, and existing method is to be installed in the metallic shield box producing the circuit of high-frequency signal or the circuit that is operated in the environment of electromagnetic field of high frequency.Existing shielding box is divided into two kinds by lid with the different of box body connected mode, and a kind of is that board-like lid is tightly connected with screw and box body, and this type shielding box is applicable to that high frequency is higher.Shortcoming is that assembling, debugging and maintenance need screw down all screws on the lid, time-consuming taking a lot of work, and the whole fit thick sheet metal that uses processes, and costs an arm and a leg.Another kind is that the bell-type lid is buckled on the box body, its structure mainly is to be made of lid 1 and box body 2 as shown in Figure 1, for guaranteeing the capability of electromagnetic shielding between lid 1 and the box body 2, be welded with contact spring 3 in the four side of bell-type lid 1, box body and lid all bend with metallic plate and form.Advantage is assembling, debugging and easy to maintenance, need not knockout screw, yet its manufacturing cost is still higher.
Because the price that above-mentioned existing shielding box exists is higher, the defective that lacks the market competitiveness, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, made the lower market competitiveness that has more of its cost in the hope of what found a kind of new structure.Through constantly research, design, and, create the utility model that has practical value finally through after studying sample and improvement repeatedly.
Summary of the invention
Technical problem to be solved in the utility model is at the above-mentioned deficiency of prior art, and to provide a kind of easily manufactured, low-cost cassette lid shielding box.
The purpose of this utility model and to solve its technical problem be to adopt following technical scheme to realize.
According to a kind of cassette lid shielding box that the utility model proposes, comprise rectangular box and rectangle lid, the four side of wherein said rectangle lid is provided with to the S of lid inboard shape curved arc, the four side junction is provided with the gap, the corresponding lid S shape curved arc position, the outside suitable for reading of described box body is provided with to outwash and holds lid, prevents that the ball of deviating from is protruding.
The purpose of this utility model and solve its technical problem and can also be further achieved by the following technical measures.
Aforesaid cassette lid shielding box, lid internal orifice size and box body corresponding overall dimension suitable for reading that the S shape curved arc top of the inboard relative side of wherein said lid is constituted are interference fit.
The utility model compared with prior art has tangible advantage and beneficial effect.By technique scheme, the utility model cassette lid shielding box can reach suitable technological progress and practicality, and has the extensive value on the industry, and its advantage is: simple in structure, lower cost, need not weld reed, greatly convenient construction cuts down finished cost, increase economic efficiency, on practicality of using and cost benefit, it is required to meet industry development really fully, quite has industrial utilization.
In sum, the utility model cassette lid shielding box, no matter on the structure of product or function, bigger improvement is arranged all, obvious improvement is arranged technically, and produced handy and practical effect, and more existing shielding box has the outstanding multinomial effect of enhancement, thus be suitable for practicality more, and have the extensive value of industry, really be a new and innovative, progressive, practical new design.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, and for above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.
Description of drawings
Fig. 1 is the structure chart of existing shielding box.
Fig. 2 is the structure chart of the utility model cassette lid shielding box.
Embodiment
Relevant aforementioned and other technology contents, characteristics and effect of the present utility model can clearly present in the following detailed description that cooperates with reference to graphic preferred embodiment.Explanation by embodiment, when can being to reach technological means that predetermined purpose takes and effect to get one more deeply and concrete understanding to the utility model, yet appended graphic only provide with reference to the usefulness of explanation, be not to be used for the utility model is limited.
See also shown in Figure 2, a kind of cassette lid shielding box provided by the utility model, comprise rectangular box 10 and rectangle lid 11, the four side of wherein said rectangle lid 11 is provided with to the S of lid inboard shape curved arc 12, the four side junction is provided with gap 13, corresponding lid S shape curved arc 12 positions, the outside suitable for reading of described box body 10 are provided with to outwash and hold lid, prevent the ball of deviating from protruding 14.
Lid internal orifice size and box body 10 corresponding overall dimensions suitable for reading that S shape curved arc 12 tops of described lid 11 inboard relative sides are constituted are interference fit.
The four side of the utility model lid S shape curved arc to the inside and the gap of side junction, constitute lid with elastic sides, adopting lid internal orifice size and box body overall dimension suitable for reading is interference fit, when covering, the strain of utilizing four side S shape curved arc to the inside to produce makes side and box body have certain contact force between suitable for reading, thereby reaches the effect of tight contact.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
