Description

A kind of radome and pcb board

Technical field

This utility model relates to electronic technology field, particularly relates to a kind of radome and pcb board.

Background technology

Radome is widely used in the field such as mobile phone, GPS, is used for preventing electromagnetic interference, to the electronic component on pcb board and LCM plays shielding action.The development of integrated circuit has driven miniaturization and the densification of electronic component, increasing electronics unit device Part concentrates on a small region.As it is shown in figure 1, radome 1 great majority are by SMT (Surface Mount Technology table Face encapsulates) technique and tin cream be together welded on pcb board 2, and during welding, the off normal of radome 1 will result in radome 1 and other electricity The conducting of sub-components and parts, and then have the risk of short circuit, even result in the damage of whole circuit board unrepairable.

Utility model content

Technical problem to be solved in the utility model is: occur displacement or inclined when radome is welded in PCB The phenomenon moved.

In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of radome, including cover body frame Frame, described enclosure frame includes that at least one can be inserted into the DIP foot of pcb board.

Further, described DIP foot is longer than other legs.

Further, the height of described DIP foot is 1.2-1.6mm.

Further, described DIP foot is a pair, is positioned at enclosure frame diagonal angle corner.

Further, described DIP foot is two right, is positioned at four corners of enclosure frame.

A kind of pcb board, described pcb board is provided with at least one for the receiving hole accommodating radome DIP foot.

Further, described pcb board there is a pair DIP foot receiving hole.

Further, described pcb board there are two pairs of DIP foot receiving holes.

Further, the degree of depth of described receiving hole is 1.2-1.6mm.

The beneficial effects of the utility model are: by designing at least one DIP foot on radome enclosure frame, welding Time, DIP foot is inserted in pcb board, can realize being accurately positioned of radome, and radome is relative to the skew of PCB horizontal direction and shakes Momentum is the least, can avoid the conducting of radome and other electronic devices and components, largely reduces the risk of short circuit；If shielding The receiving hole that cover DIP foot is not inserted on pcb board, radome magnitude of inclination can relatively big or the serious skew of generation, electricity in the case of this Sub-components and parts can quickly note abnormalities radome jack-up and process in time during detection before SMT.

Detailed description of the invention

By describing technology contents of the present utility model in detail, being realized purpose and effect, below in conjunction with embodiment and join Conjunction accompanying drawing is explained.

The design of this utility model most critical is: designs at least one on radome enclosure frame and can be inserted into pcb board DIP foot, can realize being accurately positioned of radome during welding, reduce skew, it is to avoid radome is led with other electronic devices and components Logical, largely reduce the risk of short circuit.

Refer to Fig. 2 and Fig. 3, a kind of radome, including enclosure frame, described enclosure frame includes that at least one can be inserted Enter the DIP foot of pcb board.

Knowable to foregoing description, the beneficial effects of the utility model are: design DIP foot on radome enclosure frame, During welding, DIP foot is inserted in pcb board, it is achieved being accurately positioned of radome, reduces the skew of horizontal direction and rocks, it is to avoid screen Cover the conducting of cover and other electronic devices and components, largely reduce the risk of short circuit.

Further, described DIP foot is longer than other legs.

Seen from the above description, DIP foot is longer than other legs is inserted in pcb board, it is achieved location, if radome DIP foot is not inserted into pcb board, and radome magnitude of inclination can be relatively big or serious skew occurs, and in the case of this, electronic devices and components can be Radome jack-up, can quickly note abnormalities and process in time during detection before SMT.

Further, the height of described DIP foot is 1.2-1.6mm.

Seen from the above description, the height of DIP foot can adjust according to specific needs.

Seen from the above description, when DIP foot is a pair or two pairs, radome can be made preferably to be positioned on pcb board, Reduce side-play amount further.

This utility model further relates to a kind of pcb board, and described pcb board is provided with at least one for accommodating radome DIP foot Receiving hole.

Seen from the above description, pcb board is provided with the receiving hole of special receiving DIP foot, coordinates radome to realize location.

Further, described pcb board there is a pair DIP foot receiving hole.

Further, described pcb board there are two pairs of DIP foot receiving holes.

Seen from the above description, on pcb board the quantity of receiving hole and position by the quantity of the DIP foot on radome and position Depending on.

Further, the degree of depth of described receiving hole is 1.2-1.6mm.

Seen from the above description, the degree of depth of receiving hole is as the criterion can accommodate DIP foot.

Embodiment

Refer to Fig. 2 and Fig. 3, embodiment one of the present utility model is: a kind of radome, including enclosure frame 3, described cover Body framework 3 includes that at least one can be inserted into the DIP foot 4 of pcb board, is provided with at least one for accommodating DIP foot 4 on pcb board Receiving hole.

Preferably, the length of described DIP foot 4 is longer than other leg, so that DIP foot 4 is inserted in pcb board, it is achieved Location.

Optionally, the height of described DIP foot 4 is 1.2-1.6mm；Preferably, the degree of depth of described receiving hole and described DIP foot The height of 4 matches, and is also 1.2-1.6mm.

Preferably, described DIP foot 4 is a pair, is positioned at enclosure frame diagonal angle corner, and further preferred DIP foot 4 is two Right, it is positioned at four corners of enclosure frame, so that radome location is better achieved, at utmost reduces side-play amount；Preferably, institute State quantity and the position consistency of the quantity of receiving hole and position and DIP foot 4.

In the present embodiment, when radome is welded on pcb board, DIP foot 4 is firstly inserted into the receiving hole on pcb board, right Radome positions, and is together welded on pcb board with tin cream the most again；When radome DIP foot 4 is not inserted on pcb board accommodating Kong Shi, radome magnitude of inclination can be relatively big or serious skew occurs, in the case of this electronic devices and components can radome jack-up, Can quickly note abnormalities and process in time during detection before SMT.
