Abstract
The utility model relates to a USB terminal with a structure of terminal grooves of different widths. The USB terminal comprises male terminals and female terminals. The width of the upper edge of the terminal groove of each female terminal is less than the width of the lower edge by 0.5-3cm. The female terminals are arranged inside a plastic housing. The female terminal is a female terminal of a USB mini-B-type connector. 2-20 female terminal grooves are arranged on the same connector. Compared with the prior art, the USB terminal has advantages of convenient usage, reliability and the like.
Description
Technical field
The utility model relates to a kind of USB terminal structure, especially relates to a kind of USB terminal with not wide terminal groove structure.
Background technology
At present, the terminal groove structure of most of USB Mini-B female ends is upper and lower wide designs, but the design of this wide terminal groove has the defect of three aspects:
1. terminal groove width design is wide: in the time that USB Mini-B male end is not inserted female end product, be that the head of female end product terminal is in free state, terminal groove can not carry out the adjustment of normotopia degree to terminal head, make in the time that male end end inserts, male terminal can not be sat in the right seat with female end terminal, may have the risk of loose contact.
2. terminal groove width design is narrow: when USB Mini-B male end is extracted after female end product, be that the head of female end product terminal is in free state, the narrow terminal head that may make of terminal groove contacts with terminal plastic cement cell wall, can not free resilience, while making male end end insertion next time, terminal can not provide enough positive forces, thereby has the risk of loose contact.
3. for avoiding above 2 risks, need to do strict management and control to plastic cement well width size and terminal width dimensions, finished product yield is on the low side, and mold repair cost is also very large.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of USB terminal with not wide terminal groove structure in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of USB terminal with not wide terminal groove structure, comprise male terminal, female end terminal, and it is characterized in that, the terminal groove top width of described female end terminal is less than following width.
The terminal groove top width of described female end terminal is than the little 0.5～3cm of following width.
Described female end terminal is placed in plastic shell.
Described female end terminal is the female end terminal of the mini Type B connector of USB, and same connector is provided with 2～20 female end terminal grooves.
Above-mentioned not wide terminal groove structure: because the size of USB Mini-B product own is less, the sectional area design of terminal is very limited, so need to guarantee contact reliability under the design conditions of existing small and weak terminal, design a kind of novel not wide terminal groove structure, be that top width is little, width is large below.In the time that USB Mini-B male end is not inserted female end product, be the head of female end product terminal in free state, less upper end pilot trench can carry out the adjustment of normotopia degree to terminal head, makes in the time that male end end inserts, can sit in the right seat with male terminal, reach contact reliability.When USB Mini-B male end is extracted after female end product, be that the head of female end product terminal is in free state, wider lower end pilot trench can avoid terminal head to contact with terminal plastic cement cell wall, free resilience, while making male end end insertion next time, terminal can continue the positive force that provides enough, thereby it is reliable to reach contact.
Compared with prior art, the utlity model has following advantage:
1. in the time that USB Mini-B male end is not inserted female end product, be the head of female end product terminal in free state, less upper end pilot trench can carry out the adjustment of normotopia degree to terminal head, makes in the time that male end end inserts, can sit in the right seat with male terminal, reach contact reliability.
2. when USB Mini-B male end is extracted after female end product, be that the head of female end product terminal is in free state, wider lower end pilot trench can avoid terminal head to contact with terminal plastic cement cell wall, free resilience, while making male end end insertion next time, terminal can continue the positive force that provides enough, thereby it is reliable to reach contact.
3. the optimization in design, can suitably relax management and control to plastic cement well width size and terminal width dimensions, and finished product yield can be guaranteed, and mold repair cost is also relatively low.

Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Fig. 1～2, a kind of USB terminal with not wide terminal groove structure, comprises male terminal, female end terminal, and terminal groove 1 top 11 width of described female end terminal 2 are less than following 12 width, and top 11 width are than the little 0.5～3cm of following 12 width.
Described female end terminal is placed in plastic shell 3.
Described female end terminal is the female end terminal of the mini Type B connector of USB, and same connector is provided with 2～20 female end terminal grooves.
Above-mentioned not wide terminal groove structure: because the size of USB Mini-B product own is less, the sectional area design of terminal is very limited, so need to guarantee contact reliability under the design conditions of existing small and weak terminal, design a kind of novel not wide terminal groove structure, be that top width is little, width is large below.In the time that USB Mini-B male end is not inserted female end product, be the head of female end product terminal in free state, less upper end pilot trench can carry out the adjustment of normotopia degree to terminal head, makes in the time that male end end inserts, can sit in the right seat with male terminal, reach contact reliability.When USB Mini-B male end is extracted after female end product, be that the head of female end product terminal is in free state, wider lower end pilot trench can avoid terminal head to contact with terminal plastic cement cell wall, free resilience, while making male end end insertion next time, terminal can continue the positive force that provides enough, thereby it is reliable to reach contact.
