Existing a kind of double row's needle connector that is used for printed circuit board (pcb board), it comprises plastic body and plurality of rows pin, the plurality of rows pin is arranged in double being located on the plastic body.This double row's needle connector, the end face of its plastic body is the plane, the bottom surface of plastic body is a concave surface, inconsistent because of the shrinkage of end face and bottom surface often in the plastic body injection mo(u)lding, cause finished product plastic body warpage excessive, produce dry joint or rosin joint phenomenon when making the welding of double row's needle connector and position, pcb board hole, influenced the electric connection performance.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art, provide a kind of anti-warpage double row's needle connector, the shrinkage of end face and bottom surface is more consistent during the plastic body injection mo(u)lding of this connector, the warpage of finished product plastic body is less, produce dry joint or rosin joint phenomenon when avoiding welding, improve welding quality, guarantee to electrically connect performance.
For achieving the above object, the utility model is achieved through the following technical solutions: the anti-double row's needle connector of warpage, it comprises plastic body and plurality of rows pin, the plurality of rows pin is arranged in double being located on the plastic body, the bottom surface of described plastic body is a concave surface, and the end face of described plastic body offers some tops groove.
Described some tops groove respectively the row's of being opened in pin row be listed as between.
Described plastic body is positioned at the top groove location and offers the slotted hole that connects plastic body.
The two sides, front and back of described plastic body all offer the plurality of side groove.
Described plurality of side groove respectively the row's of being opened in pin row be listed as between, and each side groove respectively with the top groove of the relevant position formula groove that fuses.
Row's centreline spacing PH of described double row's pin is 2.54 ± 0.10mm, and row's pin centreline spacing ZH of the adjacent row's pin of every row is 2.54 ± 0.10mm.
The height H of described plastic body is 2.50 ± 0.15mm.
The width W of described plastic body is 5.00 ± 0.15mm.
Described row's pin is vertical bar formula row pin.
The utility model beneficial effect is: the double row's needle connector of anti-warpage described in the utility model, the end face of its plastic body offers some tops groove, but adopt its end face of plastic body balance of this structure and the architectural difference of bottom surface, difference in shrinkage when reducing the plastic body moulding, thereby the warping phenomenon of minimizing finished product plastic body, therefore, the warpage that the utlity model has the finished product plastic body is less, produce dry joint or rosin joint phenomenon when avoiding welding, improve welding quality, guarantee to electrically connect the advantage of performance.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is a right view of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1 to Figure 3, the anti-double row's needle connector of warpage, it comprises plastic body 1 and plurality of rows pin 2, row's pin 2 is vertical bar formula row pin, plurality of rows pin 2 is arranged in double being located on the plastic body 1, and the bottom surface of described plastic body 1 is a concave surface 3, and the end face of described plastic body 1 offers some tops groove 4.In the present embodiment, described some tops groove 4 respectively the row's of being opened in pin 2 row be listed as between.
