Abstract
The invention relates to a surface-mount quartz crystal electronic component comprising an electronic component used as a resonator or a filter. An insulated square housing sleeves the electronic component. A protruded block is arranged on the bottom, corresponding to a lead wire end of the electronic component, of the housing. A lead wire is bent backwardly to be located on the protruded block. The surface-mount quartz crystal electronic component has beneficial effects that a conventional surface-mount quartz crystal resonator or filter is additionally provided with the insulated square housing; the resonator or filter is arranged in the insulated square housing; and the lead wire is bent backwardly to be fixed in a horizontal groove on the protruded block on the bottom of the housing. The design of the protruded block enables the lead wire of the electronic component to be higher than the bottom surface of the housing so that the bottom surface of the housing is prevented from influencing the surface mount of the lead wire of the electronic component.
Description
Technical field
The present invention relates to electronic applications, be specifically related to a kind of surface-pasted quartz crystal electronic element.
Background technology
External existing shaping surface mounting quartz crystal resonator (being called for short: SMD crystal), SMD crystal is in process for making, fine setting operation uses electronic laser rifle equipment, press seal operation uses resistance seam welding machine, this equipment is extremely expensive, cause SMD crystal selling price high, be generally used in the electronic product of small volume, domestic production 49U/S quartz-crystal resonator (is called for short: 49U crystal, price comparison is cheap) manufacturer's 49S crystal add the insulating trip of a synthetic plastic after, the pin leads of 49U/S crystal is fallen to two lateral bendings, reach surface-pasted object (being commonly called as false SMD crystal in row), this false SMD crystal manifests on surface mount production line: rosin joint, the phenomenons such as dry joint, with the naked eye be difficult to find, can detect with instrument, the reprocessed product causing surface mount production line to produce line increase, if rosin joint potential a bit, dry joint phenomenon then can affect the product quality after dispatching from the factory.Reason is: this false SMD crystal, and profile is irregular positive, and chip mounter is scanning because of not having reliable benchmark to locate in the process that aligns, the patch location deviation causing components and parts too greatly, beyond deviation range.Be commonly called as: " pasting oblique ".And although real SMD crystal can surface mount but cost is too high.
Summary of the invention
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of surface-pasted quartz crystal electronic element, comprise the electronic component for resonator or filter, the square shell of one deck insulation is set with in the outside of electronic component, the bottom that the corresponding electronic component of described shell arranges lead end is provided with projection, and lead-in wire backward bending is on described projection.
Further, described projection is provided with the groove placing described lead-in wire.
Further, the cross section of described shell is in square.
Further, the cross section of described shell is rectangle.
The invention has the beneficial effects as follows: by setting up the square shell of an insulation on existing surface mounting quartz crystal resonator or filter, resonator or filter are placed in shell, then the bending backward that gone between is fixed in the horizontal groove on outer casing bottom projection.The design of projection, makes the height of leads of electronic component higher than enclosure bottom, avoids the impact that enclosure bottom mounts electric leads.
Accompanying drawing explanation
Fig. 1 is invention overall structure schematic diagram.
In accompanying drawing, the list of parts representated by each label is as follows:
1, shell 2, electronic component 3, lead-in wire 4, projection, 5, groove.
Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of surface-pasted quartz crystal electronic element, comprises the electronic component 2 for resonator or filter, is set with the square shell 1 of one deck insulation in the outside of electronic component 2, preferred: the cross section of described shell 1 is in square.Or rectangle.What add that the quartz-crystal resonator of shell 1 or filter can mount other Surface Mount Component,s of picture attachment is neat, and guarantee is without rosin joint, dry joint.
The bottom that the corresponding electronic component 2 of described shell 1 arranges lead end is provided with projection 4, and lead-in wire 3 backward bending is on described projection 4.Preferred: described projection 4 is provided with the groove 5 placing described lead-in wire 3, lead-in wire is in groove, by setting up the square shell 1 of an insulation on existing surface mounting quartz crystal resonator or filter, resonator or filter are placed in shell 1, then are gone between in 3 horizontal grooves 5 that bending is fixed on shell 1 bottom projections 4 backward.The design of projection 4, makes the height of lead-in wire 3 higher than enclosure bottom, avoids the impact that enclosure bottom mounts lead-in wire 3.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
