The utility model has convenient processing and strong operation manufacturability; the internal stress generated by temperature impact and mechanical vibration on the plate-shaped capacitor is eliminated, and the connector has extremely high contact reliability.
Description
Technical field
The utility model relates to a kind of contact of planar array filtering connector, belongs to the filter connector technical field.
Background technology
Filter connector: be meant in connector inside filter has been installed,, make connector have certain anti-electromagnetic interference capability as electric capacity or magnet ring etc.
The tabular electric capacity of planar array: a kind of multi-layer ceramic chip stacked, number by contact has designed several capacitor groups in parallel, all negative plates are all connected, and the ground connection that links to each other with shell, and positive plate forms plated-through hole one by one with roasting silver or gold process, is used for the contact of end joint connector.
Planar array filtering connector:, obtain the connector of filter function at the tabular electric capacity of inner mounting plane array.This connector is called as third generation filter connector.
At present, industry uses tabular electric capacity as third generation filter connector core institution in a large number.Mostly the termination mode of this connector is welding, and the contact that is about to connector embeds and is installed in the plated-through hole of tabular electric capacity, and uses anchor clamps location, welding then.Its deficiency be at weld easily because of vibration, thermal expansion etc. cause internal stress, ceramic material is broken, cause filter connector to lose efficacy.
The patent DE19815488 in 2000 of ITT Corp., a kind of filter connector that adopts the Elastic Contact body is disclosed, as shown in Figure 1, this Elastic Contact body is to make the three road muscle grooves that interlace in the copper strips upper punch, volume is round then, and three road muscle form the convex closure shown in the piece number 66 among Fig. 1, this convex closure can with the plated-through hole Elastic Contact of tabular electric capacity, thereby realize the elasticity termination.
Another part patent US6508672 in 2003 of ITT Corp. discloses a kind of method that adopts the plated-through hole Elastic Contact that length of spring compressed realizes connector contact and tabular electric capacity as shown in Figure 2, and wherein 110 is described springs.
Summary of the invention
The purpose of this utility model provides a kind of novel contact body of planar array filtering connector, in the plated-through hole and connector contact Elastic Contact of realizing electric capacity, make the filter connector production and processing convenient, contact reliability and environmental suitability are more superior.
For achieving the above object, the Elastic Contact body of planar array filtering connector described in the utility model is formed by multiply high-performance metal alloy skein silk system, and this Elastic Contact body vertically is provided with a plurality of fat points, when being connected in the connector, wherein at least one fat point and connector contact Elastic Contact, at least one fat point and tabular electric capacity Elastic Contact.
Above-mentioned Elastic Contact body metal alloy wires comprises inner layer metal alloy silk and outer layer metal alloy silk, inner layer metal alloy silk is opposite with outer layer metal alloy silk articulation direction, strand system back outer layer metal silk envelope forms a circle, and the inner layer metal silk is enough placed in its inner space.
Aforesaid inner layer metal thread number is preferential to adopt 3 strands, and outer layer metal thread number preferentially adopts the 7-10 thigh.
The metal alloy wires of above-mentioned Elastic Contact body is an acid bronze alloy, preferably adopts beryllium-bronze or tin bronze.
Described Elastic Contact body can pass through the fat aftershaping of strand system, cut-out, laser spot welding and big and heavy stone.
Form towards fat because the fat point of this Elastic Contact body is a strands of metal wire strand system, therefore form the multiple spot contact, contact reliability is very high, the fat elastic compression that when connecting, is subjected to, connector has good environmental suitability like this, and connector inserts when separating, and needed power is very soft.
In sum, the utility model has the advantages that:
1, contact is easy to process, and operative weldability is strong;
2, eliminated the internal stress that temperature shock, mechanical oscillation produce tabular electric capacity;
3, the how fat point elasticity contact structures that adopt the strands of metal wire coiling to form have high contact reliability.

Embodiment
Below in conjunction with the utility model accompanying drawing embodiment, the utility model content is described in further detail.
Be illustrated in figure 3 as the utility model Elastic Contact body example structure schematic diagram, this Elastic Contact body 2 is formed by multiply acid bronze alloy skein silk system, how much relevant with wire self diameter its number of share of stock is, the inner layer metal silk 12 of the utility model embodiment is 3 strands, outer layer metal silk 11 is 7 strands, during the strand system, the inner layer metal silk is opposite with outer layer metal skein silk system direction; Outer layer metal silk 11 envelopes are circular after the articulation, and inner layer metal silk 12 should be enough placed in its inner space that forms.
After the wire that strand makes length was as required cut off, wire two ends G and H were fused together strands of metal wire by laser spot welding, prevent filoselle.Press as shown in Figure 3 subsequently, clamping straightway corresponding site (D, E and F position among promptly final formation Fig. 3), utilize anchor clamps to apply enough power at wire two ends G and H, the final Elastic Contact body 2 that forms with two fat somes 2a and 2b, when guaranteeing that this Elastic Contact body is connected in the electric connector, one of them fat some 2a contacts with contact 1, and this contact can be a contact pin contacting piece, also jack contact, contact 1 as shown in Figure 5 is a jack contact; Another fat some 2b contacts with tabular electric capacity 7, and when it contacts, the fat point of Elastic Contact body by compression, when it separated, fat point restored to the original state.
Because this Elastic Contact volume surrounding wire is 7 strands, therefore as fat some 2a and 2b during respectively with contact 1 and tabular electric capacity 7 Elastic Contact, the point of 7 envelopes of formation this shows that Elastic Contact body of the present utility model can improve the reliability of electrical connection greatly.
