[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1-7 A terminal with high insertion mechanical properties shown includes a terminal body 1, a comparative terminal a8, and a comparative terminal b10;

[0023] The interior of the terminal body 1 is respectively provided with a first-stage elastomer 2, a second-stage elastomer 3, a third-stage elastomer 4, a fourth-stage elastomer 5 and a fifth-stage elastomer 6 from bottom to top. When testing the usage condition of the terminal body 1, a force between sixty and one hundred and seventy Newtons is first used to insert and contact the PCB board. During the insertion test, the actual measured results of the terminal body 1 equipped with a first-stage elastomer 2, a second-stage elastomer 3, a third-stage elastomer 4, a fourth-stage elastomer 5 and a fifth-stage elastomer 6 are close to the target requirements and similar to the simulation results. The overall situation is smooth, so it can be adapted to the PCB board and put into mass production.

[0024] like Figure 2 and Figure 3 As shown, the first-stage elastomer 2, the second-stage elastomer 3, the third-stage elastomer 4, the fourth-stage elastomer 5 and the fifth-stage elastomer 6 are all Z-shaped, and the first-stage elastomer 2, the second-stage elastomer 3, the third-stage elastomer 4, the fourth-stage elastomer 5 and the fifth-stage elastomer 6 are placed in opposite and staggered positions. The second-stage elastomer 3, the third-stage elastomer 4 and the fourth-stage elastomer 5 are the same, and the first-stage elastomer 2 and the fifth-stage elastomer 6 are the same.

[0025] The Z-shaped first-stage elastomer 2, second-stage elastomer 3, third-stage elastomer 4, fourth-stage elastomer 5 and fifth-stage elastomer 6 are smoother during the test than the W-shaped elastomer 9 and the I-shaped elastomer 11. During the test, the force values ​​of the upper and lower limit states of the W-shaped elastomer 9 and the I-shaped elastomer 11 are quite different and not smooth enough. The staggered and different first-stage elastomer 2, second-stage elastomer 3, third-stage elastomer 4, fourth-stage elastomer 5 and fifth-stage elastomer 6 can ensure that their Z-shape is more stable and can maintain the stability rate when in use.

[0026] like Figure 2 and Figure 3 As shown, the first-stage elastomer 2, the second-stage elastomer 3, the third-stage elastomer 4, the fourth-stage elastomer 5 and the fifth-stage elastomer 6 are formed by integrated stamping, and the thickness of the first-stage elastomer 2, the second-stage elastomer 3, the third-stage elastomer 4, the fourth-stage elastomer 5 and the fifth-stage elastomer 6 at the bevel is one third of the thickness of the terminal body 1.

[0027] Compared with the W-shaped elastic body 9 and the I-shaped elastic body 11, the Z-shaped one-stage elastic body 2, the second-stage elastic body 3, the third-stage elastic body 4, the fourth-stage elastic body 5 and the fifth-stage elastic body 6 are easier to stamp and form, thereby reducing the defective product rate in production.

[0028] like Figure 1 、 Figure 4 and Figure 6 As shown, the upper outer wall of the terminal body 1 is fixedly connected to the terminal 7, and the left and right outer walls of the terminal body 1 are provided with blocks to be inserted into the specified position for position fixation. In contrast, the terminal a8 is provided with a W-shaped elastic body 9 inside, and the terminal b10 is provided with an I-shaped elastic body 11 inside.

[0029] By abutting the terminal 7 against the PCB board for testing, the blocks at the left and right ends of the terminal body 1 can be inserted into the corresponding slots on the corresponding plate, and the W-shaped elastomer 9 in the terminal a8 and the I-shaped elastomer 11 in the terminal b10 are compared with the Z-shaped first-stage elastomer 2, second-stage elastomer 3, third-stage elastomer 4, fourth-stage elastomer 5 and fifth-stage elastomer 6 inside the terminal body 1, so as to test the more suitable terminal for use.

[0030] The implementation principle of this embodiment is: when testing the usage status of the terminal body 1, first use a force between sixty and one hundred and seventy Newtons to insert and contact the PCB board. During the insertion test, the actual measured results of the terminal body 1 equipped with a first-stage elastomer 2, a second-stage elastomer 3, a third-stage elastomer 4, a fourth-stage elastomer 5 and a fifth-stage elastomer 6 are close to the target requirements and similar to the simulation results, and the overall situation is smooth, so that it can adapt to the PCB board and be put into mass production.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
