Wherein this track body side also is provided with toward the horizontally extending lug of lateral direction, and the screw that provides screw to pass is provided this lug, and screw is locked on this circuit board.

Wherein this track body also is provided with conducting strip, and this conducting strip is locked in this lug by described screw, forms with the circuit junction with circuit board to be electrically connected.

Wherein this track body also is provided with barb in contrast to a side of rail groove.

The connector track structure that the process that is provided by the utility model improves, when making connector, can adjust two interorbital gauges flexibly according to needed specification, thereby with one group of mould just can the production plurality of specifications connector, also comparatively convenient when assembling simultaneously, thereby can reduce production costs.

The conducting strip that the utility model will be used for leading the EMI circuit on the other hand is incorporated into the structure-improved of track and circuit board, to avoid utilizing welding manner conducting strip to be incorporated into the loaded down with trivial details technology of track and circuit board.

Moreover the utility model has also designed location structure with circuit board at track, makes it more easy at the group device, thereby promotes production efficiency.

In addition, the utility model is also done improvement at the structure of track and connector shell combination, thereby avoids adopting the puzzlement of the assembling inconvenience that urgent fit system brings.

Therefore, first technical characterictic of the present utility model be that two groups of track bodies that the company of being used for is incorporated into circuit board and joint are independently made, and the structure of these two groups of track bodies is identical; Therefore, two track bodies just can be assembled in the joint both sides symmetrically and be fixed on circuit board as long as exchange direction; Plant structure Design thus, no matter the dimensions of joint why, all can adjust the position that is provided with of track body according to the actual size of joint, thereby reach the flexibility of manufacturing, and as long as use one group of mould to make track body, significantly reduced manufacturing cost.

Second technical characterictic of the present utility model, be to adopt the screw that possesses conduction property that conducting strip is locked in track body and circuit board, and this screw directly is locked in the conductive junction point on the circuit board, does subsequent treatment thereby utilize conducting strip that the EMI electric current is transmitted to circuit board via screw.

The 3rd technical characterictic of the present utility model, be below track body, to be provided with horizontally extending runners, and be provided with projection in the runners bottom surface, the location hole of corresponding those projections is set on circuit board in addition, with when being assembled in track body on the circuit board, being utilized this projection to insert this screw and allow track body and circuit board obtain the location.

The 4th technical characterictic of the present utility model is that track body is provided with a plurality of barbs, when the track body after being combined in joint and circuit board further is assembled in the connector shell again, is utilized this barb and connector shell to be fastened.

Therefore, Improvement type connector track structure provided by the utility model has the following advantages:

Once, can produce two siding tracks that can share with one group of mould, make integral production become instinct significantly to reduce.

Two, two groups of track systems are independent of the joint manufacturing, therefore can elasticity to be adjusted the distance between two track bodies in response to the actual size specification of joint, and the more known connector track structure of the flexibility of manufacturing is higher.

Three, the utility model has location structure between track body and circuit board, therefore, when assembling, is able to give the location earlier by this location structure, thereby promotes the stability and the convenience of assembling.

Four, the utility model is fixed in connector shell by overhead structure with the track body combination, is promoted the convenience and the production efficiency of assembling.
