Next, a method of separating the power connection terminal structure 10 will be described:
because the left deformation wingspan 210 is provided with the left fastening groove 211 with a semi-closed structure, and the right deformation wingspan 220 is provided with the right fastening groove 221 with a semi-closed structure, when the left deformation wingspan 210 and the right deformation wingspan 220 are pressed by the left hand and the right hand respectively, the left clamping block 411 can jump from the left fastening groove 211, and the right clamping block 421 can jump from the right fastening groove 221, so that the separation of the male connector 20 and the female connector 30 is realized rapidly.
As shown in fig. 2 and fig. 3, in the present embodiment, the left plug 410 and the right plug 420 are both cylindrical structures, the left clamping block 411 is disposed on a sidewall of the left plug 410, and the right clamping block 421 is disposed on a sidewall of the right plug 420. Further, the left clamping block 411 is a quarter truncated cone structure, and the left clamping block 411 has a left inclined guide surface 412; the right side joint block 421 is a quarter-cone structure, and the left side joint block 421 has a right side inclined guide surface 422.
As shown in fig. 2 and 3, the left side joint block 411 is a quarter round platform structure, and on the basis of realizing stable joint with the left side fastening groove 211, an avoiding space is provided for subsequent quick separation, and the left side joint block 411 can be easily separated as long as the left side deformation wingspan 210 is lightly pressed. If the left clamping block 411 is a whole truncated cone structure, the whole truncated cone occupies the space of the left fastening slot 211, and when the left deformation wing span 210 is pressed, the left clamping block 411 is difficult to separate. The left engaging block 411 has a left inclined guide surface 412, and the insertion can be more smoothly performed by providing the left inclined guide surface 412. The right side snap block 421 is the same, and will not be described in detail here.
As shown in fig. 2 and fig. 3, in the present embodiment, the plate surface area of the male fastening plate 200 is larger than the cross-sectional area of the male body 100; the plate surface area of the female fastening plate 400 is greater than the cross-sectional area of the female body 300. Such structural design, the edge that is equivalent to public first mounting plate 200 protrudes in public first body 100, and the edge protrusion in female first body 300 of female first mounting plate 400, the place that the protrusion comes can provide bigger area of contact with people's finger contact, makes things convenient for the application of force.
As shown in fig. 3, in the present embodiment, the left deformation span 210 has a left pressing end 212, and the left pressing end 212 is located at the notch edge of the left fastening slot 211; the right side morphing span 220 has a right side pressing end 222, and the right side pressing end 222 is located at the notch edge of the right side fastening slot 221. Pressing end 212 and right side through setting up the left side and pressing end 222, having increased area of contact, make things convenient for the staff to press end 212 and right side through pressing and press end 222 and then drive left side deformation span 210 and right side deformation span 220 and take place the deformation.
As shown in fig. 4, in the present invention, a metal insertion piece 500 is provided in the male connector body 100.
As shown in fig. 5 and 6, the metal patch 500 includes a fixing portion 510 and a mating portion 520 connected to the fixing portion 510. The insertion part 520 includes two elastic pieces 521 spaced apart from each other, and a middle transition space 530 is formed at a connection position of the two elastic pieces 521 and the fixing part 510.
As shown in fig. 5 and 6, the metal patch 500 further includes an injection-molded overflow preventing blocking frame 540, and the injection-molded overflow preventing blocking frame 540 blocks the intermediate transition space 530.
It should be noted that the male connector 20 is obtained by injection molding, and during the injection molding process, if the injection molding anti-overflow blocking frame 540 is not disposed at the middle transition space 530, the injection molding plastic will flow into the space between the two elastic sheets 521 through the middle transition space 530, so that the two elastic sheets 521 do not have good elastic deformation due to the injection molding plastic, and in addition, the corresponding insertion rod on the female connector 30 cannot penetrate into the space between the two elastic sheets 521, thereby causing the phenomenon of improper insertion.
The intermediate transition space 530 is blocked by an injection molding overflow-preventing blocking frame 540, so that the above problems can be well avoided.
With respect to the injection molded overfill prevention block frame 540, there are two embodiments as follows:
example one
As shown in fig. 6, the fixing portion 510, the two elastic sheets 521 and the injection-molded spill-proof blocking frame 540 are integrally formed. It is understood that the fixing portion 510, the two elastic pieces 521 and the injection-molded spill-proof blocking frame 540 are integrally formed by punching. Although the finished product can be obtained quickly by the method, a tiny gap appears on the injection molding anti-overflow blocking frame 540, and a very small amount of injection molding glue can enter the space through the gap in the injection molding process.
Example two
As shown in fig. 7 and 8, the injection molding anti-overflow blocking frame 540 is a plastic structure. The injection molding anti-overflow blocking frame 540 is installed in a manual mode before injection molding, no gap occurs in the injection molding anti-overflow blocking frame 540 with the structure, the middle transition space 530 can be completely blocked, and injection molding glue cannot enter the space in the injection molding process.
The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
