Fig. 6 is a perspective view of a female housing part of the electrically conductive reliable BTB connector of the present invention, which mainly includes a female housing insulator 21 (shown in fig. 7) and a female housing terminal 22 (shown in fig. 8). The female socket terminals 22 are fixed on the female socket insulator 21 and correspond to the male socket terminals 12 in position. The female socket terminal 22 is formed by connecting a female solder tail portion 221, a female fixing portion 222, and a female conduction portion 223 in this order. And at least one splitting groove 2231 is formed along the width extending direction (i.e., the left and right direction) of the female conduction part 223 to form a plurality of female split conduction units 2232, and the splitting grooves are respectively and independently inserted into the corresponding male socket terminals 12, so as to ensure the stability and reliability of the contact between the male socket terminals 12 and the female socket terminals 22 after the assembly is completed, ensure the effective contact area, and further eliminate the influence of the manufacturing error and the assembly error on the signal conduction stability to a certain extent.
