Detailed Description

In the description of the present invention, it should be understood that the terms "left", "right", "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

In the following, the contents of the present invention will be described in further detail with reference to the specific embodiments, and fig. 3 shows an exploded view of a BTB connector having high insertion stability according to the present invention, and it can be seen that the BTB connector 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. 7 is a perspective view showing a male socket portion of the BTB connector with high insertion stability according to the present invention, which mainly includes a male socket insulator 11 (shown in fig. 8) and a male socket terminal 12 (shown in fig. 9) fixed to the male socket insulator 11. The male socket terminal 12 is formed by connecting a male solder foot 121 and a male conduction part 122 in this order. A male insertion step 1221 is provided on an outer side wall of the male conduction portion 122. Fig. 10 is a perspective view of a female housing part of the BTB connector with high insertion stability according to the present invention, which mainly includes a female housing insulator 21 (shown in fig. 11) and a female housing terminal 22 (shown in fig. 12). 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 includes a female solder leg portion 221, a female fixing portion 222, and a female conduction portion 223 connected in sequence. The female conduction part 223 has a U-shaped longitudinal section for the insertion of the male conduction part 122. The female conduction portion 223 includes a resilient arc-shaped conduction section 2231, which is formed by extending a free end thereof. A female insertion step 2232 adapted to the male insertion step 1221 is provided on an inner side wall of the female conduction portion 233. Thus, when the male socket 1 is inserted in place relative to the female socket 2, the male insertion step 1221 and the female insertion step 2232 are hooked to each other (as shown in fig. 4, 5, and 6), so as to effectively improve the contact reliability of the male socket terminal 12 and the female socket terminal 22, reduce the probability of the separation phenomenon caused by the external force, and ensure the stability of signal transmission.

As a further refinement of the above-described BTB connector structure having high insertion stability, the male insertion step 1221 is formed by downwardly and flatly cutting the free-end outer side wall of the male conduction part 122 (as shown in fig. 9). The female insertion step 2232 is formed by a free end inside wall of the female conduction portion 223 being cut flat along the length thereof (as shown in fig. 12).

In view of improving the smoothness of the hooks of the male engagement step 1221 and the female engagement step 2232, the engagement surface of the male engagement step 1221 is inclined with respect to the horizontal plane, and the inclination angle is controlled to be 30-60 °, and the female engagement step 2232 is also inclined accordingly (as shown in fig. 6).

Further, in order to secure 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 a plug-in manner, that is, a plug-in projection 2221 (shown in fig. 12) is extended outward on both the left and right sides of the female fixing portion 222, and correspondingly, a plug-in through groove 211 (shown in fig. 11) adapted to the plug-in projection 2221 and extending in the vertical direction is formed in the female socket insulator 21.

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.

Finally, the female socket terminal 22 further has a necking portion 224, which is formed by symmetrically cutting the front and rear side walls thereof, and extends from the female fixing portion 222 to the female conduction portion 223 (as shown in fig. 12), so as to have a large elastic deformation capability, which is beneficial to smoothly executing the hooking processes of the male insertion step 1221 and the female insertion step 2232, and preventing the occurrence of the clamping stagnation phenomenon; on the other hand, the female socket terminal 22 and the male socket terminal 12 are kept in a good elastic contact state, and the stability of signal transmission 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.
