Description

Technical Field

[0001] The utility model relates to a connector tail clip, in particular to an integrated connector tail clip which is resistant to high and low temperatures and has a long service life. Background Art

[0002] Existing connector tail clips are usually integrated, with the upper and lower covers connected together by a connecting portion, but the connecting portion will break after being bent several times, and this breakage phenomenon will increase in high or low temperature environments. Utility Model Content

[0003] In view of the deficiencies in the existing technology, the utility model provides an integrated connector tail clip which is resistant to high and low temperatures and has a long service life.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an integrated connector tail clip that is resistant to high and low temperatures and has a long service life, including an upper cover, a lower cover and a connecting part, the connecting part is connected to the upper cover and the lower cover end to end, and the middle part of the connecting part is provided with a joint part with grooves on the upper and lower parts.

[0005] There is an arc transition between the two ends of the connecting part and the joining part.

[0006] A plurality of card slots are arranged on both sides of the upper cover.

[0007] A plurality of buckles are provided on both sides of the lower cover.

[0008] Beneficial effects of the utility model: The utility model achieves a long bending life in high and low temperature environments. After being placed at -40℃ and +125℃ for 24 hours, it is folded 1,000 times without breaking. In addition to PE or PP materials, the utility model can also use PA materials to achieve application scenarios with higher strength requirements, while eliminating the strengthening process in injection molding, improving product application scenarios and life while also reducing production costs.

[0015] Embodiment 1, as Figure 1-Figure 3 As shown, an integrated connector tail clip that is resistant to high and low temperatures and has a long service life includes an upper cover 1, a lower cover 2 and a connecting portion 3. The connecting portion 3 is connected end to end with the upper cover 1 and the lower cover 2, and a connecting portion 4 with grooves on the upper and lower parts is provided in the middle part of the connecting portion 3. The thickness of the connecting portion 4 is set according to the minimum thickness that the material can be formed. The connecting portion 4 requires a certain length to bear the deformation so that the internal stress of the connecting portion 4 is a smooth transition. This stress is much lower than the yield strength, ensuring that the connecting portion 4 will not break and can meet the life requirements after high and low temperature environments. The connecting portion 4 can be bent. When bending, the groove on the inner side of the connecting portion 3 needs to have a certain depth. After bending, a certain space is formed to accommodate the deformation of the squeezed part and reduce the stress at the bending part.

[0016] There is an arc transition between the two ends of the connecting portion 3 and the joint portion 4, which is more conducive to the flow of plastic during injection molding.

[0017] Both sides of the upper cover 1 are provided with a plurality of slots 5, and correspondingly, both sides of the lower cover 2 are provided with a plurality of buckles 6. After being bent, the slots 5 of the upper cover 1 and the buckles 6 of the lower cover 2 are fixedly connected.

[0018] Embodiment 2, as Figure 4 As shown, a connecting portion 4 having grooves on the upper and lower sides is provided in the middle portion of the connecting portion 3. The difference between this embodiment and the first embodiment is that the heights of the grooves on the upper and lower sides of the connecting portion 4 are different.

[0019] Embodiment three, as Figure 5 As shown, a connecting portion 4 with grooves on the upper and lower sides is provided in the middle part of the connecting portion 3. The difference between this embodiment and the first embodiment is that the bottoms of the grooves on the upper and lower sides of the connecting portion 4 are arc-shaped.

[0020] Embodiment 4, as Figure 6 As shown, the connecting portion 3 is provided with a coupling portion 4 with grooves on the upper and lower sides. The difference between this embodiment and the first embodiment is that the grooves completely cover the upper and lower sides of the connecting portion 3.

[0021] The above shows and describes the basic principle, main features and advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, simple changes and substitutions by ordinary technicians in this field are within the protection scope of the utility model.
