Micro universal serial convergence bar shell

Abstract

The invention relates to a miniature outer case of an universal serial bus, which comprises an outer case body, a subulate pin and a fork type pin, with the subulate pin stretching outwards from the outer case body; the fork type pin stretches outwards from the outer case body and comprises two elastic chips arranged in pairs, a groove formed between the two elastic chips and extending outwards from the outer case body, and two breaches formed counter to the groove and at the outer side of the each elastic chip, wherein, the breaches of the two neighboring elastic chips are front and back displaced in position and form an 'overhead hook' structure with the elastic chips. The miniature outer case of a universal serial bus, when in a plug-in connection with a substrate, hereby can tightly be connected with the substrate owing to the 'overhead hook' structure formed by the breaches of the elastic chips, is applicable to different substrates of different thickness and achieves an applying performance of firm connection owing to the front and back displacement of the breaches.

Description

technical field [0001] The invention relates to a miniature universal serial bus bar housing, in particular to a miniature universal serial bus bar housing which has the function of stable connection and is applicable to different substrate thicknesses. Background technique [0002] Please refer to FIG. 1 and FIG. 2. FIG. 1 is an exploded perspective view illustrating the structure of a general miniature universal serial bus bar housing, and is used to match a terminal block and a plurality of conductive terminals. FIG. 2 is a schematic diagram illustrating the combined state of the above-mentioned miniature universal serial bus housing and a substrate. Generally, the miniature universal serial bus bar housing 100 is combined with a terminal block 101 and a plurality of conductive terminals 102 to form a complete miniature universal serial bus bar connector. Usually, the miniature universal serial bus bar housing 100 will be It is combined and fixed with a substrate 103 so ...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned structure can make the miniature universal serial bus case 100 and the substrate 103 be combined and fixed, the fixing effect is not significant in essence, because the micro universal serial bus case 100 and the substrate 103 are fixed. The main point of focus is the protruding tooth tip concentrated on the tooth surface 133, because the contact area is very small and the friction force is very low, and it is not actually engaged on the base plate 103 but only forms a friction point, so As a result, the miniature universal serial bus housing 100 is unstable in assembly; in addition, since the guide pin 12 is not in contact with the wall of the insertion hole 104, it does not have any effect of increasing the fixation; and, If the width of the guide pin 12 is increased to fit closely with the insertion hole 104, although the friction force can be increased, the effect of the guide will be reduced and the insertion difficulty will be caused. When the force F is pulled out, it still does not have a clamping effect because it simply provides friction, so the situation that the miniature universal serial bus bar shell 100 is detached takes place, so it is often found that the miniature universal serial bus bar The row housing 100 is not tightly combined with the base plate 103, there is a gap between the two, or there may be a deflection. If the thickness of the base plate 103 is thin and the depth of the insertion hole 104 is shallow, friction will occur. The force will be smaller, and the stability of the combination will be weaker, and in the case of long-term use of the universal serial bus connector for plugging and unplugging, it may even cause a gap between the miniature universal serial bus housing 100 and the substrate 103 Serious consequences such as shaking or even detachment between

[0005] It can be seen that the above-mentioned existing miniature universal serial bus housing obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. Urgent problem
