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. 6 is a perspective view of a male socket portion of the BTB connector with anti-misplug and anti-scraping function according to the present invention, which is mainly composed of a male socket insulator 11 (as shown in fig. 7) and a male socket terminal 12 (as shown in fig. 8) fixed on the male socket insulator 11. Fig. 3 is a schematic perspective view of a female socket of the BTB connector with anti-misplug and anti-scraping function according to the present invention, which is mainly composed of a female socket insulator 21 (as shown in fig. 4) and a female socket terminal 22 (as shown in fig. 5). The female socket terminals 22 are fixed to the female socket insulator 21 in one-to-one correspondence with the positions of the male socket terminals 12 (as shown in fig. 3).

As shown in fig. 2, the anti-butting and scraping function portion 3 is constituted by a male seat guard 31 and a female seat guard 32. The number of the male socket guards 31 is set to 2, and the male socket guards are symmetrically wrapped around the left and right ends of the male socket insulator 11. The female socket guards 32 are also 2 in number and symmetrically wrapped around the left and right ends of the female socket insulator 21. Therefore, the plug-in side walls of the male socket insulator 11 and the female socket insulator 21 are effectively prevented from being subjected to scraping force, the generation of plastic scraping scraps is further avoided, the male socket terminal 12 and the female socket terminal 22 are ensured to have correct assembly positions, and the contact and conduction stability of the male socket terminal and the female socket terminal is ensured.

As a further refinement of the BTB connector structure having the anti-opposite insertion/scraping function, the male holder guard 31 is mainly composed of several parts, such as a male holder top arm 311, a male holder connecting arm 312, a male holder bottom arm 313, a male holder front side arm 314, and a male holder rear side arm 315. Wherein the male seat connecting arm 312 is connected between the male seat top arm 311 and the male seat bottom arm 313. The male housing front side arm 314 and the male housing rear side arm 315 are formed by bending the front and rear free ends of the male housing bottom arm 313 upward (as shown in fig. 8), so as to achieve a fixed connection with the male housing insulator 11 and ensure a reliable protection of the ends thereof.

Similar to the design concept described above, the female guard 32 is mainly composed of a top arm 321, and several parts including an end fixing arm 322, an end contact arm 323, a front fixing arm 324, a front contact arm 325, a rear fixing arm 326, and a rear contact arm 327, which are bent and extended downward from the top arm 321 (as shown in fig. 5). The end-side fixing arm 322 and the end-side contact arm 323, the front-side fixing arm 324 and the front-side contact arm 325, and the rear-side fixing arm 326 and the rear-side contact arm 327 are respectively oppositely clamped inside and outside the periphery of the female socket insulator 21 (as shown in fig. 3), so that the fixed connection between the end-side fixing arm and the female socket insulator 21 is realized, and the reliable protection of the end part is ensured.

In the injection molding stage, the male and female seat guards 31 and 32 may be pre-placed in the cavities of the injection molds of the male and female seat insulators 11 and 21, respectively, to form a gapless assembly. In addition, after molding, the male seat protection member 31 and the female seat protection member 32 are also subjected to the action of plastic wrapping force, so that the fixation firmness of the male seat protection member and the female seat protection member is further enhanced, the phenomena of position deviation and even separation of the male seat protection member and the female seat protection member caused by stress in the subsequent application process are prevented, and the reliable protection of the left end part and the right end part of the male seat insulator 11 and the female seat insulator 21 is ensured.

Fig. 9 and 10 are schematic perspective views of a female seat protection member and a male seat protection member in another embodiment of the connector with an anti-misplug and anti-scraping function according to the present invention, which are different from the above-mentioned technical solutions in that: the female and male seat guards 32 and 31 are additionally provided with connection reinforcements, so that the coupling force between the female seat guard 32 and the female seat insulator 21 and between the male seat guard 31 and the male seat insulator 11 is further improved, and the reliability of fixation is ensured. The implementation is recommended to be carried out by referring to the following scheme: the female guard 32 has a first female connection reinforcement 328 extending in the front-rear direction on the front side wall and/or the rear side wall of the end-side fixing arm 322. The front fixing arm 325 and the rear fixing arm 326 are provided with a second female connector reinforcement 329 extending in the left-right direction on the left side arm and/or the right side wall thereof. In the molding stage of the female socket insulator 21, the first female socket connecting reinforcement 328 and the second female socket connecting reinforcement 329 are also pre-placed in the cavity of the injection mold; with respect to the male guard 31, a male connection reinforcement 316 is formed extending downward along the left side wall or/and the right side wall of the male top arm 311 thereof. In the molding stage of the male insulator 11, the male connection reinforcement 316 is also pre-placed in the cavity of the injection mold.

Generally, good signal conduction can be achieved only by welding and fixing the male socket terminal 12, the female socket terminal 22 and the corresponding PCB. Of course, the male socket protection member 31 and the female socket protection member 32 may also serve as connection terminals, and in actual operation, both of them also need to be soldered and fixed to the corresponding PCB by soldering, thereby further increasing the conduction area and ensuring the stability and reliability of signal transmission.

Finally, in the prior art, the male and female housings 1 and 2 are held in the mated state only by the force between the male and female terminals 12 and 22. In practical applications, it is found that when the BTB connector is subjected to an external impact force, the male seat 1 is easily separated from the female seat 2, which affects the stability of signal transmission. To this end, the front side contact arm 325 of the female seat guard 32 may also be arcuately curved in the front-to-rear direction to form a front resilient contact portion 3251. The rear side contact arm 327 may be arcuately curved in a rear-to-front direction to form a rear elastic contact portion 3271 (as shown in fig. 5). Thus, after the BTB connector is inserted and assembled, the male seat protection member 31 and the female seat protection member 32 are in an elastic contact state, and both are under the action of elastic pressure, so that the relative friction force between the male seat protection member 31 and the female seat protection member 32 is enhanced, the stability of the inserted and assembled state of the male seat part 1 and the female seat part 2 is further enhanced, the loosening phenomenon in the later application process is prevented, and the good transmission of signals is ensured.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
