Abstract

The utility model provides a mutually-clamped shield cover, which is characterized by being made of sheet metal parts and comprising an upper shield cover and a lower shield cover, wherein the upper shield cover comprises a top surface and a side wall, the lower shield cover comprises a bottom surface and a side wall, and the side walls of the upper shield cover and the lower shield cover are in clamp connection via internal and external buckles. A PCB board is provided with a through hole, the upper shield cover and the lower shield cover are arranged at the two sides of the PCB board, a hasp penetrates through the through hole for connection, and double-side shield is realized without welding, thus the mutually-clamped shield cover is simple in mounting and convenient in dismounting, can greatly reduce work hours when a product needs repair, and can be widely used in electronic communication products.

Description

A kind of radome of mutual engaging

Technical field

The invention belongs to the telecommunications field, be specifically related to the structural design of radome.

Background technology

Along with the development of telecommunications product, chip integration is increasingly high, and the problem of anti-shielding is more and more outstanding.Mostly traditional two-piece type radome is a screening cover and a shielded rack, and wherein shielded rack is welded on the PCB, and wall dashes salient point is arranged, and then screening cover is placed on above the shielded rack, and this scheme is merely able to the single face shielding.

The utility model content

The technical problem that the utility model will solve is: a kind of radome of mutual engaging is provided, realizes two-sided shielding.

The utility model is to solve the problems of the technologies described above the technical scheme of being taked to be: a kind of radome of mutual engaging; It is characterized in that: it is processed by sheet metal component; Comprise radome and following radome; Last radome comprises end face and sidewall, and following radome comprises bottom surface and sidewall, and the sidewall of upper and lower radome is by inside and outside buckle clamping.

Press such scheme, the described radome of going up comprises rectangular top and 4 sidewalls, connects mutually between the adjacent sidewall, and at least 2 sidewalls are provided with draw-in groove and to the outer buckle that extends below (or interior buckle); Described radome down comprises rectangular bottom surface and 4 sidewalls, and at least 2 sidewalls are provided with draw-in groove and upwardly extending interior buckle (or outer buckle); The draw-in groove of last radome is complementary with the interior buckle (or outer buckle) of following radome correspondence position, and the outer buckle of last radome (or interior buckle) and the draw-in groove of following radome correspondence position are complementary.

Press such scheme, 1-2 outer buckle is set on each sidewall of said upward radome, the total length of outer buckle is the 30%-70% of sidewall length.

Press such scheme, the edge of junction is provided with the resiliency supported pin between the described adjacent wall.

The beneficial effect of the utility model is:

1, perforation is set on pcb board, upper and lower radome is on the two sides of pcb board, and inside and outside buckle passes the perforation clamping; Need not welding and realized two-sided shielding, and convenient disassembly is installed easily; When particularly product needed is reprocessed, can greatly reduce work hours, can be widely used in the telecommunications product.

2, adopt sheet metal component to be made, utilized sheet metal component better elastic and thermal conductivity, guaranteed the folding of buckle, and improve thermal diffusivity, the operate as normal of protection chip when making shielding.

3, the resiliency supported pin is set up at the edge of junction between adjacent wall, and the place that makes upper and lower radome contact with pcb board is supported by the resiliency supported pin, in order to avoid pcb board is worn.

Embodiment

Fig. 1 is the stereogram of the utility model one embodiment open mode, and Fig. 2 is the utility model one embodiment user mode cutaway view, is processed by sheet metal component, comprises radome and following radome, and upper and lower radome is connected by inside and outside buckle.Last radome comprises rectangular top 2 and 4 sidewalls 1, connects mutually between the adjacent sidewall, and each sidewall is provided with draw-in groove 5 and to the outer buckle 3-1 that extends below, the top of outer buckle 3-1 is the knuckle that bends inwards; Described radome down comprises rectangular bottom surface 4 and 4 sidewalls 1, and each sidewall is provided with draw-in groove 5 and upwardly extending interior buckle 3-2, and the top of interior buckle 3-2 is the knuckle that outwards bends; The draw-in groove of last radome is complementary with the interior buckle 3-2 of following radome correspondence position, the outer buckle 3-1 of last radome and the draw-in groove of following radome correspondence position coupling.The edge of junction is provided with resiliency supported pin 6 between the adjacent wall.

During installation, chip 7 is set on the pcb board 8, and around chip 7, perforation is set, upper and lower radome outward, interior buckle are passed the perforation on the pcb board 8 simultaneously, snap in corresponding draw-in groove 5 then; During dismounting, the knuckle that at first interior buckle is outwards bent advances in the radome and makes two buckles open, and simultaneously upper and lower radome is taken off again.

An outer buckle is set on each sidewall of radome on the utility model, and the wild card button bit is put and is in the middle of the sidewall, and the length of outer buckle is 60% of sidewall length.

Claims

1. mutual radome of engaging, it is characterized in that: it is processed by sheet metal component, comprises radome and following radome, and last radome comprises end face and sidewall, and following radome comprises bottom surface and sidewall, and the sidewall of upper and lower radome is by inside and outside buckle clamping.

2. the radome of mutual engaging according to claim 1 is characterized in that: the described radome of going up comprises rectangular top and 4 sidewalls, connects mutually between the adjacent sidewall, and at least 2 sidewalls are provided with draw-in groove and to the outer buckle that extends below; Described radome down comprises rectangular bottom surface and 4 sidewalls, and at least 2 sidewalls are provided with draw-in groove and upwardly extending interior buckle; The draw-in groove of last radome is complementary with the interior buckle of following radome correspondence position, and the outer buckle of last radome is complementary with the draw-in groove of following radome correspondence position.
