In an embodiment of the utility model, the pins of the DB connector are connected with the corresponding pins of the connecting terminals on the PCB through the PCB.

In one embodiment of the utility model, the pins of the PCB terminal block are connected with the PCB by welding.

In one embodiment of the utility model, a wire pressing plate is arranged between the bosses of the positioning holes in the base shell, and the cross section of the wire pressing plate is the same as that of the wire inlet of the base shell.

In one embodiment of the utility model, the PCB board and the base shell form a detachable structure through the card slot.

In an embodiment of the present invention, the PCB terminal block is provided with a plurality of screw type rail terminals.

Compared with the prior art, the utility model has the advantages that: this neotype joint Assembly design is simple scientific, compact structure, and the data line can be directly fixed on the pin that PCB binding post row corresponds through the screwdriver according to the stitch that corresponds, need not to adopt traditional soldering tin mode, and convenient and fast can dismantle repeatedly, used repeatedly many times.

Drawings

In order that the present disclosure may be more readily and clearly understood, reference will now be made in detail to the present disclosure, examples of which are illustrated in the accompanying drawings.

Fig. 1 is a schematic view of a base housing structure of a solderless DB connector tab assembly.

Fig. 2 is a schematic view of the internal structure of a solderless DB connector tab assembly.

Fig. 3 is a complementary illustration of the expanded internal structure of a solderless DB connector tab assembly.

As shown in the figure: 1. the PCB comprises a base shell, 2, DB connectors, 3, handle long screws, 4, a PCB board, 5, a PCB wiring terminal row, 6, self-tapping screws and 7, and a wire pressing plate.

Detailed Description

As shown in fig. 1, 2 and 3, the present embodiment provides a soldering-free DB connector tab assembly including:

the connector comprises a base shell 1, wherein a DB connector 2 is assembled at one end of the base shell 1, a handle long screw 3 is arranged in a clamping groove of the base shell 1, and the base shell can be fixed with another end connector nut on a computer through the handle long screw;

the PCB 4 is arranged in the base shell 1, and the pin end of the PCB 4 is connected with a PCB wiring terminal strip 5;

and the self-tapping screw 6 is arranged in the positioning hole on the surface of the base shell 1.

The base shell 1 is divided into an upper shell and a lower shell.

As the improvement, the upper shell is connected with the lower shell through the sawtooth-shaped clamping grooves, so that the connection strength is further enhanced, and the buckle-type shell can be detached and reused for many times.

And pin numbers are marked on the PCB 4.

And pins of the DB connector 2 are correspondingly welded on the PCB 4 according to the pin numbers.

As the improvement, 2 stitches of DB connector link to each other through PCB board 4 and the corresponding pin of binding post on the PCB board 4, conveniently be used for signal high quality transmission.

And the pins of the PCB wiring terminal block 5 are connected with the PCB 4 through welding.

The base shell 1 in be equipped with line ball board 7 between the location hole boss, just line ball board 7 cross-sectional shape with base shell 1 inlet wire the same, the usable self tapping screw of data line is fixed on the shell with the line ball board, firm reliable.
