The following provides a more detailed description of the present invention with reference to specific embodiments,

fig. 3 shows an exploded view of a BTB connector having high welding strength according to the present invention, and it can be seen that it is mainly composed of a male seat portion 1 and a female seat portion 2. The male seat portion 1 is disposed right above the female seat portion 2, and is connected to the female seat portion 2 in an opposite insertion manner, so as to achieve signal conduction.

Fig. 4 shows a perspective view of a male socket portion of a BTB connector with high welding strength according to the present invention, which includes a male socket insulator 11 (shown in fig. 5) and a male socket terminal 12 (shown in fig. 6). The male socket terminal 12 is fixed in the male socket insulator 11 and is welded and fixed with the first PCB. The male socket terminal 12 is provided with a male solder foot portion 121, which is arranged in parallel with the first PCB and attached thereto. Fig. 7 shows a perspective view of a female socket portion of the BTB connector with high welding strength according to the present invention, which includes a female socket insulator 21 (shown in fig. 8) and a female socket terminal 22 (shown in fig. 9). The female socket terminal 22 is fixed in the female socket insulator 21, corresponds to the male socket terminal 12 in one-to-one position, and is welded and fixed to the second PCB. A female solder tail portion 221 is provided on the female socket terminal 22, and is arranged in parallel with the second PCB board and attached thereto.

It should be emphasized that a first welding opening slot 1211 (shown in fig. 6) is formed on the male solder tail 121; a second welding opening groove 2211 (shown in fig. 9) is formed in the female leg portion 221. Welding and filling are carried out in the process of welding with the PCB, so that the length value of a connecting welding line between the connecting terminal (comprising the male seat terminal 12 and the female seat terminal 22) and the PCB is increased in a phase-changing manner, the connecting strength is improved, and the phenomenon that the connecting terminal and the PCB are separated in the practical application process to influence the reliability and the stability of signal transmission is prevented.

Of course, the number of the first welding open groove 1211 and the second welding open groove 2211 may be multiple according to practical situations, and the first welding open groove 1211 and the second welding open groove 2211 are respectively and uniformly distributed along the width direction (i.e. the left and right direction in the drawing) of the male welding foot portion 121 and the female welding foot portion 221.

Generally, for manufacturability of molding, the first weld opening slot 1211 is preferably inwardly extended from the edge of the male fillet portion 121 (as shown in fig. 6), and the second weld opening slot 2211 is preferably inwardly extended from the edge of the female fillet portion 221 (as shown in fig. 9), so as to reduce molding difficulty and manufacturing cost of the male and female socket terminals 12 and 22.

Of course, as another modified design of the above solution, the first weld opening 1211 may also be a rectangular groove or a circular groove (as shown in fig. 10) away from the edge of the male fillet portion 121. The second welding opening slot 2211 may also be a rectangular slot or a circular slot away from the edge of the female leg portion 221 (as shown in fig. 11).

Finally, in order to ensure the fixing reliability and the assembling convenience of the female socket terminal 22 and the female socket insulator 21, the female socket terminal 22 is preferably fixed in the female socket insulator 21 in an inserting manner (as shown in fig. 7), and the left and right sides thereof are extended with inserting projections 222 (as shown in fig. 9), and correspondingly, the female socket insulator 21 is provided with an inserting through groove 211 (as shown in fig. 8) which is adapted to the inserting projections 222 and extends in the vertical direction.

Of course, as a modified design of the above technical solution, the female socket terminal 22 may also be integrally injection molded with the female socket insulator 21, which is as follows: in the injection molding stage, the female socket terminals 22 are pre-installed in the cavities of the injection mold of the female socket insulator 21, respectively, to form a gapless assembly. In addition, after molding, the female socket terminal 22 is also acted by the plastic wrapping force, so that the fixation firmness of the two terminals is further enhanced, and the phenomenon that the female socket terminal is subjected to position deviation or even is separated from the female socket terminal in the subsequent application process is prevented. The male socket terminal 12 and the male socket insulator 11 are connected and fixed by the molding method described above.
