Abstract
The utility model discloses a soft-contact rubber liner between a ceramic crystal resonator and a contact point of a leading wire piece in a ceramic filter and a resonator. The liner is formed by combining a conduction region made of conductive rubber and an insulating region made of insulating rubber. Using the utility model to assemble the ceramic parts not only can ensure the reliable contact and conduction of the contact point of each leading wire piece and a counter electrode on the ceramic crystal resonator but also can avoid the short circuit among each electrode on the ceramic crystal resonator and among each leading wire piece, thus satisfying the performance requirement of the ceramic parts. The utility model can be manufactured in mass by using Chinese available materials and technologies and has the advantages of simple manufacturing process, low cost, reliable performance and easy installation.
Description
The utility model is the part of ceramic component (ceramic filter, ceramic resonator etc.), as the liner between ceramic crystal oscillator and the lead wire contact.
At present when making ceramic component, in order to improve the contact reliability between ceramic crystal oscillator and the lead wire contact.Simultaneously,, generally all between ceramic crystal oscillator and lead wire contact, increase one deck rubber packing, adopt soft contact also for the ceramic crystal oscillator is in the good vibration environment.In the prior art, rubber packing has two kinds of forms.A kind of is example with the rubber packing in the SFU465 type ceramic filter of Japanese Murata Manufacturing Co. Ltd. production, what it adopted is Anisotropically conductive rubber, this rubber has Anisotropically conductive, promptly any each point on rubber packing and ceramic crystal oscillator contact plane direction all insulate, and all be conducting perpendicular to the each point on any lines of contact plane direction, use this rubber packing, can guarantee that respective electrode has good conducting to contact on lead wire contact and the ceramic crystal oscillator, can avoid the short circuit between each electrode on the oscillator again, also having avoided simultaneously the short circuit between each lead wire, is a kind of comparatively desirable rubber packing.But China does not still have the ability of making this Anisotropically conductive rubber at present.Another kind of form, can be Japanese rubber packing in the FFD455 type ceramic filter produced of TDK company be example, this rubber packing is the conductive rubber coating that is produced on the lead wire contact, its shape and size are all similar with the lead wire contact, and with the ceramic crystal oscillator on shape, the size of counter electrode adapt, only need during assembling the lead wire contact directly is placed on the ceramic crystal oscillator and get final product.This also is a kind of relatively good desirable liner form, but makes the conductive rubber coating on the lead wire contact, the technology more complicated, and need to introduce know-how and equipment.
The purpose of this utility model is, designs a kind ofly to utilize that domestic material and technology just can be made, performance can meet the requirements of rubber packing equally.
The technical solution of the utility model is, geometry according to each electrode and insulation layer on the ceramic crystal oscillator, size, adopt conductive rubber to make one or more conduction regions, adopt electro-insulating rubber to make one or more insulation layers, and as required conduction region and insulation layer are combined, make and make rubber packing in this way, and be equipped with suitable lead wire and contact, after the designing requirement assembling, just can guarantee the conducting between each electrode and corresponding lead wire contact on the ceramic crystal oscillator, can avoid between each electrode again and the short circuit between the lead wire, satisfy the soft requirement that contacts between ceramic crystal oscillator and the lead wire contact.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Edge electrodes (1), isolated area (2) and central electrode (3) are arranged on the ceramic crystal oscillator (shown in Figure 1), and there is grounding electrode (4) at the ceramic crystal oscillator back side.Edge electrodes conducting district (5) and (6) of adopting conductive rubber to make should be arranged on the piece shape conduction region rubber packing (shown in Figure 3) mutually, there is the insulation isolated area (8) that adopts electro-insulating rubber to make in central electrode conducting district (7) between these two electrode conduction districts.The left and right sides of rubber packing is insulation layer, in order to isolate two lead wire (11), (14) contact with ceramic crystal oscillator top edge electrode (1).
The isolating bar (10) that all has electro-insulating rubber to make between the bus (9) that adopts conductive rubber to make, every adjacent two buss (9) is arranged on the bar shaped conduction region rubber packing (shown in Figure 5).The width and the length of bus (9) and isolating bar (10) can design according to shape, the size of each electrode and isolated area on the ceramic crystal oscillator.In the present embodiment, the width of bus (9) is consistent with the width of isolating bar (10), is narrower than 2/3 of isolated area on the ceramic crystal oscillator (2) width, and every millimeter has totally 6 to 8 of bus and isolating bars approximately.The length of bus (9) is not joined and is advisable with lead wire (11), (14) again both can satisfy the requirement that the lead wire contact contacts with counter electrode conducting on the ceramic crystal oscillator.The effect of bar shaped conduction region rubber packing left and right sides insulation layer is identical with the effect of piece shape conduction region rubber packing left and right sides insulation layer.
During the ceramic component assembling, the method shown in the map interlinking 10 is placed on rubber packing on the ceramic crystal oscillator, and edge electrodes lead wire (shown in Figure 6), central electrode lead wire (shown in Fig. 8) are placed on the rubber packing.At this moment, corresponding two bending contacts (12) contact with edge electrodes (1) on the ceramic crystal oscillator by the conduction region on the rubber packing on the edge electrodes lead wire, and the boss contact (13) on the central electrode lead wire contacts with central electrode (3) on the ceramic crystal oscillator by the conduction region on the rubber packing.Then, install the ground spring lead wire, and they are packed into together encapsulate in the plastic casing at the ceramic crystal oscillator back side.
All about 0.2mm, the insulation layer insulation resistance is greater than 100M Ω for the thickness of the described two kinds of rubber packings of present embodiment, and the conduction region contact resistance is less than 200 Ω.
Major advantage of the present utility model is that the prior art of can basing on our country and raw material are made in a large number, satisfy the needs that ceramic component is produced, and manufacture craft are simple, with low cost, reliability is high, easy to assembly.
