Abstract
The invention relates to the field of electric connector and especially to a high-speed electric connector. The high-speed electric connector comprises a housing and a contact element module. The contact element module comprises an insulator, grounding contact elements packaged in the insulator, and a shielding sheet pasted on the top side surface of the insulator. The shielding sheet is provided with contact fingers protruded inwardly. The contact fingers are downwardly inserted into the insulator. Each grounding contact element is soldered and fixed on at least one contact finger of the shielding sheet. In the high-speed electric connector, the contact fingers are disposed on the shielding sheet such that the soldering positions of the grounding contact elements and the shielding sheet are directly transferred to the insulator. Thus, larger space can be obviously provided for a connection structure in order to enlarge cooperative surfaces between the contact fingers and the grounding contact elements. Therefore, a problem is solved that the shielding sheet of the contact element module of a conventional high-speed electric connector is liable to loosen.
Description
Technical field
The present invention relates to electric connector field, particularly relate to a kind of high-speed electrical connectors.
Background technology
High-speed electrical connectors is mainly assemblied in the contact module composition in housing by housing and stacked on top of one another, contact module comprise chip insulator, be encapsulated in the contact in insulator and be fixedly mounted on the shielding sheet at insulator upside place, wherein contact is divided into signal contacting piece and signal contacting piece, in the time that multiple contact module combinations are assemblied in housing, shielding sheet, between the chip insulator of adjacent two contact modules, therefore shields sheet and is called again and between sheet, shields sheet.Because shielding sheet ground connection can be good at crosstalking mutually between Inhibitory signal, between the grounding component of shielding sheet and the contact module under it, be electrically connected, certainly, why high-speed electrical connectors can be widely used in needing the occasion of high speed, high-fidelity, high-quality signal transmission, and the ground connection of above-mentioned shielding sheet has very important contribution therein.
At present, in high-speed electrical connectors, the grounding component of the contact module electric connection mode common with shielding sheet mainly contains two kinds.One is to adopt conductive plastics to make shielding sheet, mode by injection moulding links together shielding sheet and grounding pin, the material of the production technology of this mode to contact and shielding sheet has particular/special requirement, and cost is higher, applies in being unfavorable on a large scale.
By contrast, grounding component and the another kind of connected mode of shielding between sheet just seem and comparatively easily allow people accept.It is the mode that adopts inner cabling, be that contact is to be encapsulated in insulator, wherein grounding component is provided with to the bending structure of shielding sheet projection correspondingly, shielding sheet is provided with the through hole corresponding with bending structure, the end of above-mentioned bending structure is exposed the respective side surface of insulator and is stretched in the respective through hole on shielding sheet, after shielding the accurate location of sheet, solder(ing) paste is smeared at gap place between bending structure and the hole wall of respective through hole, then will shield fixing being electrically connected of sheet and grounding component by Reflow Soldering.This connected mode has realized being connected between shielding sheet and grounding component substantially, but because shielding sheet is very thin, and after requiring welding, scolding tin can not exceed shielding sheet, so very strict to welding process requirement, assembly qualified rate is low, simultaneously bending structure with shield between sheet to deposit tin space very little, welding shields sheet afterwards and grounding component is bonding insecure, therefore in the time that vertical screen sheet is upwards exerted oneself or is being used under vibratory impulse environment, shielding sheet is all easy to split away off from insulator, and once the problems referred to above occur, the earthing failure of sheet will directly be caused shielding, naturally and understandably, the earthing failure of the shielding sheet of any one contact module all will directly reduce the transmission performance of high-speed electrical connectors.
Summary of the invention
The object of the present invention is to provide a kind of high-speed electrical connectors, the problem easily getting loose to solve the barricade of the current contact module existing for high-speed electrical connectors.
In order to address the above problem, high-speed electrical connectors is by the following technical solutions: high-speed electrical connectors, comprise housing and be assemblied in the contact module in housing, contact module comprises insulator, is encapsulated in the grounding component in insulator and is mounted on the shielding sheet on insulator upper side, on shielding sheet, there is the fingertip protruding to the inside, this fingertip stretches to downwards in insulator, together with each grounding component is welded and fixed with at least one fingertip of shielding sheet.
The fingertip of shielding sheet stretches in insulator by patchhole set on insulator, the hole wall matched in clearance of fingertip and patchhole.
Described patchhole is the through hole that connects insulator upper and lower side.
The end of described fingertip is provided with U-lag, and grounding component is arranged in corresponding U-lag and the cell wall matched in clearance with U-lag.
Described fingertip is bent and is formed by stamping-out.
In sheet one of described insulator and shielding is provided with reference column, and another is provided with location hole, the plug-in and interference fit of described reference column and location hole.
On the shielding sheet of the contact module of this high-speed electrical connectors, there is the fingertip protruding to the inside, and fingertip stretches in insulator downwards, together with each grounding component is welded and fixed with at least one fingertip of shielding sheet.It is in fact to have made grounding component " initiatively " in existing contact module into shielding sheet " initiatively " with the form that contacts of shielding sheet to contact with grounding component, in the prior art, due to shielding sheet thinner and require scolding tin can not higher than shielding sheet, therefore shield position only actually that sheet coordinates with grounding component and be the section on the thickness direction of shielding sheet, certainly, the size of this section is and is limited, this cannot link together shielding sheet and grounding component certainly firmly, but in the contact module of this high-speed electrical connectors, because be is provided with fingertip on shielding sheet, this has directly transferred to grounding component and the welding position of shielding sheet in insulator, obviously have larger space for syndeton is set, increase the mating surface between fingertip and grounding component, thereby the problem that the barricade that solves the current existence of the contact module for high-speed electrical connectors easily gets loose.
Further, after making the hole wall matched in clearance of fingertip and patchhole, can in welding grounding component and fingertip, fingertip be welded on insulator, further improve its fixing reliability; After patchhole is made as to through hole, can be convenient carry out welding job, in other words, be fingertip can be inserted from one end of patchhole, then carry out welding operation from the other end of patchhole; Gap between U-lag and cell wall thereof and grounding component is in order to increase the mating surface in the time welding between grounding component and fingertip; It is integral type structure with shielding sheet that stamping-out bends the fingertip forming, and is more prone to proof strength; Reference column and location hole have played the effect of location insulator and shielding sheet on the one hand, have also played on the other hand the effect of fixing the two, have shared the burden of insulator with shielding sheet.
