Abstract

The utility model provides a locking structure of a shielding case and an electric device using the structure. The locking structure of the shielding case is used for fixing the shielding case on a printed circuit board and comprises a first straight arm (13), a second straight arm (14) and a bottom arm (15) connecting the two straight arms (13, 14); a bump (11) is formed on the first straight arm (13) and an elastic sheet (12) is formed on the second straight arm (14). The locking structure of the shielding case provided by the utility model can conveniently fix and fetch out the shielding case without needing to arrange a shielding frame, thus leading a PCB plate to be conveniently maintained.

Description

A kind of radome locking mechanism and use its electronic installation

Technical field

The utility model relates to the electronic component shielding harness, relates in particular to a kind of radome locking mechanism and uses its electronic installation.

Background technology

In the telecommunications industry,, generally adopt the metallic shield cover structure for suppressing to pass through of the interference of the electromagnetic wave of spatial transmission to electronic equipment.The mode that adopts is that shielded rack is welded on the printed circuit board (PCB) (PCB), and then radome is placed on the described shielded rack.Because the restriction of Sheet Metal Forming Technology and surface mounting technology (SMT) technology, after shielded rack is welded on the pcb board, make and have some zones of being inconvenient to keep in repair on the pcb board, in case the components and parts in these zones break down, in most cases, have to destroy shielded rack or utilize the hot blast welding machine that whole shielded rack is taken off, this not only makes the maintenance operation complexity, and has increased maintenance cost.

The utility model content

Technical problem to be solved in the utility model provides a kind of radome locking mechanism, uses this structure, does not need to be provided with shielded rack, just can easily radome be fixed and take out, and makes and can keep in repair pcb board easily.

For addressing the above problem, the utility model provides following technical scheme:

A kind of radome locking mechanism is used for radome is fixed on printed circuit board (PCB), comprising: first upright arm, second upright arm connect the end arm of described two upright arms; On described first upright arm, be formed with a salient point, on described second upright arm, be formed with a shell fragment.

Preferably, described two upright arms, end arm, salient point and shell fragment are punch forming.

Preferably, described salient point is the hemisphere salient point.

Preferably, described shell fragment has one and is suitable for the gradient that described radome snaps in.

The utility model also provides a kind of electronic installation that uses described radome locking mechanism, comprising: radome, radome locking mechanism and printed circuit board (PCB); Described radome is fixed on the described printed circuit board (PCB) by described radome locking mechanism.

Preferably, the end arm of described radome locking mechanism is welded on the described printed circuit board (PCB); Be formed with punching on the side arm of described radome, the side arm of the described radome of described shell fragment contact, described salient point snaps in the described punching.

Radome locking mechanism of the present utility model can be made general part, promptly can reduce device cost, can make things convenient for the dismounting of radome again, makes original pcb board cover under the shielded rack frame maintenance easily that becomes of some zones of being inconvenient to keep in repair.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.

Please refer to Fig. 1, radome locking mechanism of the present utility model comprises: two

upright arms

13,14 connect the end arm 15 of described two

upright arms

13,14; On described upright arm 13, be formed with a salient point 11, on described upright arm 14, be formed with a shell fragment 12.

The manufacture of radome locking mechanism of the present utility model is punch forming.Wherein, described salient point 11 is preferably the hemisphere salient point, and described shell fragment 12 has one and is suitable for the gradient that radome snaps in.

In actual applications, the radome locking mechanism need be welded on the pcb board by the SMT mode,, please refer to Fig. 2, sticking film 23 on the upper surface 21,22 of two

upstanding walls

13,14 of this radome locking mechanism for ease of SMT welding.

Please refer to Fig. 3, for the structural representation of the matching used radome of described radome locking mechanism.This radome is by punch forming, and is formed with punching 32 on the sidewall 31 of radome, and the position of punching and number come to determine according to demand, are not limited on a sidewall.

Please refer to Fig. 4～6, be the practical application of described radome locking mechanism, that is: in electronic installation, radome is fixed on the pcb board by described radome locking mechanism.Specific implementation is:

The diapire 15 of radome locking mechanism is welded on the pcb board 42, then radome 43 is installed on the radome locking mechanism 44.Compound action by salient point on the radome locking mechanism 11 and shell fragment 12, make the side arm 31 of the described radome of described shell fragment 12 contacts, and salient point 11 is snapped in the punching 32 on the radome side arm 31, thereby make pcb board, radome locking mechanism and radome become integral body.

Should be noted that at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spiritual scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
