Description

Simple and easy crystal resonator

Technical field

The utility model relates to a kind of electronic devices and components, relates in particular to a kind of volume quartz-crystal resonator little, simple in structure.

Background technology

At present, the R&D and production of crystal resonator, increasingly ultrathin, miniaturization, but existing crystal resonator, all need substrate top to extend and be provided with lug boss, and clamp and be connected with shell body by this lug boss, so that be connected firmly between shell body and crystal resonator pedestal.But the substrate bumps portion that substrate is provided with, has strengthened overall dimensions, the production cost of crystal resonator greatly.

Utility model content

Technical problem to be solved in the utility model is: provide a kind of structure more simple crystal resonator, and then dwindle the volume of crystal resonator, and reduce the production cost of crystal resonator.

For addressing the above problem, the technical solution of the utility model is: a kind of simple and easy crystal resonator, the pedestal that it comprises shell body and is made up of two pins, two insulators and horizontally disposed substrate, each pin top is equipped with shell fragment, shell fragment top is supported with quartz wafer, described substrate comprises horizontal wall, the both sides of described horizontal wall are provided with symmetrically vertically wall, the upper surface of described vertical wall is higher than the upper surface of horizontal wall, described vertical wall is used for being connected between shell body, and described pin upper end is exposed to the upper surface of substrate horizontal wall; Described shell body has the upper casing that jointly surrounds annular seal space with substrate, and this upper casing parallels with substrate, is all vertically extended with the lower folder side shell matching with the vertical wall of substrate two from upper casing two outer ends downwards.Described each lower folder side shell extends internally and is useful on the holder shell of supporting substrate, and this holder shell is parallel to substrate.

Between the outer surface of the vertical wall of described lower folder side shell and substrate, be connected by zinc-plated; Between described holder shell and the lower surface of the vertical wall of substrate, be also connected by zinc-plated.

Adopt technique scheme, the utility model beneficial effect is: in the utility model between resonator base and shell body by the lower folder side shell in the vertical wall in substrate two ends and shell body, holder shell connects, thereby solve in existing crystal resonator when pedestal is connected with shell body, to the dependence of substrate bumps portion, on while substrate, horizontal wall height is lower than the design of the vertical wall in two ends, can make pin, shell fragment, quartz wafer, the height of shell body is corresponding reduction all, reduce the overall volume of crystal resonator, the cancellation of substrate bumps portion simultaneously, also make crystal resonator overall structure more simple, production cost is lower.

brief description of the drawings

The schematic diagram of Fig. 1, existing resonator;

The structural representation of the crystal resonator that Fig. 2, the utility model are announced.

embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1, in the structure of existing crystal resonator, the pedestal that comprises shell body 6 and formed by two pins 2, two insulators 3 and horizontally disposed substrate 1, substrate 1 top is extended with substrate bumps portion 7, each pin 2 tops are equipped with shell fragment 4, and shell fragment 4 tops are supported with quartz wafer 5, the crystal resonator of this structure, being connected between its pedestal and shell body 6, relying on substrate bumps portion 7 and clamp realization with shell body 6.So existing crystal resonator is because the existence of substrate bumps portion 7 not only makes crystal resonator overall volume larger, higher, and complex structure, production cost are high.

As shown in Fig. 2, the simple and easy crystal resonator that the utility model is announced, it comprises shell body 6 and by two pins 2, the pedestal that two insulators 3 and horizontally disposed substrate 1 form, each pin 2 tops are equipped with shell fragment 4, shell fragment 4 tops are supported with quartz wafer 5, described substrate 1 comprises horizontal wall 12, the both sides of described horizontal wall 12 are provided with symmetrically vertically wall 13, described vertical wall 13 for and shell body 6 between be connected, the upper surface of described vertical wall 13 is higher than the upper surface of horizontal wall 12, described pin 2 upper ends are exposed to the upper surface of substrate 1 horizontal wall 12, so just can make pin 2, shell fragment 4, quartz wafer 5, the height of shell body 6 is corresponding reduction all, reduce the overall volume of crystal resonator.

Simultaneously, described shell body 6 has the upper casing 10 that jointly surrounds annular seal space 8 with substrate 1, this upper casing 10 parallels with substrate 1, all vertically be extended with the lower folder side shell 9 matching with 1 liang of vertical wall 13 of substrate downwards from 10 liang of outer ends of upper casing, between the outer surface of the vertical wall 13 of described lower folder side shell 9 and substrate 1, be connected by zinc-plated.Between resonator base and shell body 6, just can realize with the lower folder side shell 9 in shell body 6 by the substrate 1 vertical wall 13 in two ends like this, break away from the dependence to substrate bumps portion 7, also simplify the overall structure of crystal resonator, reduce production cost.

In addition, described each lower folder side shell 9 extends internally and is useful on the holder shell 11 of supporting substrate 1, this holder shell 11 is parallel to substrate 1, between the lower surface of described holder shell 11 and substrate 1 vertical wall 13, be connected by zinc-plated, the use of holder shell 11 can make to be connected between resonator base and shell body 6 more tight, firm.

In sum, the utility model can reduce the overall volume of crystal resonator, and the cancellation of substrate bumps portion 7, also makes crystal resonator overall structure more simple simultaneously, and production cost is lower.
