Abstract
The utility model discloses an install IO high speed connector in accurate positioning of upper plate, including the plastic casing, two convex reference columns of bottom shaping of plastic casing, the cell body has been offered at the middle part of reference column, and the side shaping of reference column has protruding reining in. The utility model discloses positioning accuracy is high, and the precision is high when inserting, and electrical contact performance and reliability are better.
Description
Technical field
The utility model relates to high speed connector technical field, especially relates to a kind of pinpoint IO high speed connector being arranged on upper plate.
Background technology
Along with the high speed development of information technology and people are to the continuous increase of demand data, a large amount of transfer of data is also more and more higher for the requirement of message transmission rate.High speed connector, comprises the development of back panel connector, board to board connector and the I/O connector speed that also forward is higher.Improve the transmission rate of connector, just must ensure the signal quality of signal under higher frequency transmission rate.Signal quality is on the transmit path signal integrity, leading indicator comprise harass, loss and impedance etc.IO high speed connector, with ExaMAXIO high speed connector for representative, needs to make product remain on the centre of pcb board, but its shell upper plate is still inadequate in precision location, it is lower to slotting precision, to electrical contact performance time slotting and reliability poor, be therefore necessary to be improved.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of pinpoint IO high speed connector being arranged on upper plate, and its positioning precision is high, high to precision time slotting, electrical contact performance and better reliability.
To achieve these goals, the technical scheme that the utility model adopts is.
Be arranged on a pinpoint IO high speed connector for upper plate, comprise plastic casing, shaping two reference columns protruded in bottom of plastic casing, the middle part of reference column offers cell body, and the side of reference column forms convex strangling.
In further technical scheme, the diagonal position reference column described in shaping respectively of the bottom surface of described plastic casing, the cell body direction of two reference columns is not identical.
In further technical scheme, described cell body is from the top of reference column to the middle part or the bottom that extend to reference column, a breach is formed at the middle part of reference column, the cell body direction of one of them reference column is parallel to X-direction, the cell body direction of another reference column is parallel to Y-direction, and X-direction is perpendicular to Y-direction.
In further technical scheme, described convex bottom of strangling along reference column extends up to the middle and upper part of reference column, and convex outer end of strangling is provided with the guide part of inclination.
Adopt after said structure, the utility model compared to the prior art advantageously: the utility model positioning precision is high, high to precision time slotting, electrical contact performance and better reliability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the amplification intention of first reference column of the present utility model.
Fig. 3 is the amplification intention of second reference column of the present utility model.
In figure: 1, plastic casing 2, reference column 3, cell body 4, convexly to strangle.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection range of the present utility model.
Embodiment, see shown in Fig. 1 to Fig. 3, a kind of pinpoint IO high speed connector being arranged on upper plate, comprises plastic casing 1, shaping two reference columns 2 protruded in bottom of plastic casing 1, it is the diagonal position shaping reference column 2 respectively in the bottom surface of plastic casing 1.The middle part of reference column 2 offers cell body 3, and the side of reference column 2 forms convexly strangles 4.Convexly strangle 4 to extend up to reference column 2 middle and upper part along the bottom of reference column 2.Described convex outer end of strangling 4 is provided with the guide part of inclination.
Cell body 3, from the top of reference column 2 to the middle part or the bottom that extend to reference column 2, forms a breach at the middle part of reference column 2.Cell body 3 direction of two reference columns 2 is not identical, and cell body 3 direction of one of them reference column 2 is parallel to X-direction, and cell body 3 direction of another reference column 2 is parallel to Y-direction, and X-direction is perpendicular to Y-direction.
The design is that IO high speed connector is arranged on upper plate, and with a kind of structure of pcb board relative positioning, the relative position of the bottom of plastic casing 1 designs two reference columns 2, and on two reference columns 2, do the design of two different directions flutings respectively, and on the relative position of two cell bodies 3, do two convexly strangle 4, when product installs upper plate, due to convex strangle 4 interference, reference column 2 can to cell body 3 Direction distortion, finally make product remain on the center of two PCB aperture positions, thus good contacting slotting reliability is provided.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
