Description

A kind of novel C-type USB terminal structure

[technical field]

This utility model relates to a kind of terminal structure, especially relates to a kind of novel C-type USB terminal structure.

[background technology]

At present, the terminal of c-type USB connector, after the male and female that different manufacturers produces is to inserting, retentivity size Differing, have is the most loose, falls at a touch.Male and female to be increased, to retentivity time slotting, must use same factory The product that family produces, but in actual life, it is difficult to ensure that the product used is same manufacturer production, Thus its use is restricted.

[utility model content]

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, it is provided that a kind of novel C-type USB terminal Structure, by increasing capacitance it is possible to increase in male and female to retentivity time slotting.

A kind of novel C-type USB terminal structure that this utility model provides, including housing, is arranged in housing Glue core and be arranged on the terminal of glue in-core, the rear end of described housing is provided with for connecting External cable Pcb board, described pcb board is connected with described terminal, and the upper surface of described housing is provided with at least one groove, One sidewall of described groove is provided with a shell fragment extended along the length direction of housing, and described shell fragment is positioned at groove Interior and shell fragment is partially protrude through the upper surface of housing.

Further, described shell fragment is a V-type shell fragment, and the v-angle of described V-type shell fragment is more than 90 degree And less than or equal to 120 degree.

Further, the length of described shell fragment is more than the half of the length of described groove and less than described groove Length.

Further, described shell fragment is formed in one with described housing.

Further, described groove is near the front end of described housing.

Further, the upper surface of described housing is provided with two grooves, and said two groove is respectively close to housing Both sides.

Further, upper surface and the lower surface of described housing is each formed with L near the side of described pcb board Type flange；Described c-type USB terminal structure also include strengthen shell, described pcb board be housed in described in add In strong shell, described L-type flange is embedded into described reinforcement shell.

Further, also include that the protecting crust being arranged in described housing, described glue core are arranged on described protection In shell.

Further, described protecting crust is made up of interconnective upper protecting crust and lower protecting crust.

Further, described terminal is made up of upper row's terminal and lower row's terminal, described upper row's terminal and lower row's end Sub and described pcb board is connected, and is provided with separator between upper row's terminal and lower row's terminal.

Compared with prior art, the beneficial effects of the utility model are: by arrange shell fragment, male end with Female seat is during to inserting, and shell fragment protrudes from the part of housing upper surface and can be extruded in groove by female seat inwall, After male end and female seat are to being plugged, shell fragment rebounds and is resisted against on female seat inwall, thus adds male and female to inserting Time retentivity, prevent from loosening, so use different manufacturers produce product time, will not loosen and drop, Range of application can not be limited, and reduces use cost, meets the use demand of people.

[detailed description of the invention]

The utility model will be further described with embodiment below in conjunction with the accompanying drawings.

Shown in seeing figures.1.and.2, a kind of novel C-type USB terminal structure that this utility model provides, suitable Male end for c-type USB connector.This c-type USB terminal structure includes housing 1, protecting crust, glue Core 2 and terminal.The material of housing 1 is metal material.Protecting crust is arranged in housing 1, and protecting crust is by phase The upper protecting crust 4 and the lower protecting crust 5 that connect form.Glue core 2 is arranged in protecting crust.Terminal is arranged on In glue core 2, terminal is made up of upper row's terminal 9 and lower row's terminal, sets between upper row's terminal 9 and lower row's terminal Having separator, play buffer action, upper row's terminal 9 is identical with lower row's terminal so that this male end and female seat pair Insert time non-directional.The rear end of housing 1 is provided with the pcb board 3 for connecting External cable, pcb board 3 It is connected with upper row's terminal 9 and lower row's terminal.In the specification and claims, the close cable of housing 1 One end be referred to as the rear end of housing 1, one end away from cable of housing 1 is referred to as the front end of housing 1, housing 1 Before and after the defined direction of end be referred to as the length direction of housing 1.

The upper surface of housing 1 is provided with at least one groove 6, and in the present embodiment, the upper surface of housing 1 is provided with Two grooves 6, two grooves 6 are respectively close to the both sides of housing 1.Groove 6 is near the front end of housing 1, far From pcb board 3.One sidewall of groove 6 is provided with a shell fragment 7 extended along the length direction of housing 1, shell fragment 7 are positioned at groove 6 and shell fragment 7 is partially protrude through the upper surface of housing 1.Male end and female seat during to inserting, Shell fragment 7 protrudes from the part of housing 1 upper surface can be by female seat inwall toward extruding in groove 6, in male end with female After seat is to being plugged, shell fragment 7 rebounds and is resisted against on female seat inwall, thus adds male and female to holding time slotting Power, prevents from loosening.

Shell fragment 7 is a V-type shell fragment, and the v-angle of V-type shell fragment is more than 90 degree and less than or equal to 120 degree. V-type shell fragment is easier to be resisted against on female seat inwall, thus ensure that male and female is to retentivity time slotting.

The length of shell fragment 7 half more than the length of groove 6 and the length less than groove 6.As it is shown in figure 1, Length L1 of shell fragment 7 represents, length L2 of groove 6 represents, i.e. 1/2L2 ＜ L1 ＜ L2. Can ensure that shell fragment 7 can favorably accomplish the action being extruded and rebounding in groove 6.

In the present embodiment, shell fragment 7 is formed in one with housing 1, it is simple to manufacture.

In the present embodiment, upper surface and the lower surface of housing 1 are each formed with L-type near the side of pcb board 3 Flange 8, the L-type flange 8 of housing 1 upper surface is symmetrical with the L-type flange 8 of housing lower surface, C Type USB terminal structure also includes strengthening shell (being not drawn on figure), and pcb board 3 is housed in reinforcement shell, L-type flange 8 is embedded into reinforcement shell.

This utility model is when specifically used, and male end and female seat are during to inserting, and shell fragment 7 protrudes from shell The part of body 1 upper surface can be by the extruding force from female seat inwall, and shell fragment 7 is extruded in groove 6, After male end and female seat are to being plugged, under the elastic reaction of shell fragment 7 self, shell fragment 7 rebounds, and is resisted against On female seat inwall, thus add male end and retentivity during female seat, prevent from loosening, so use difference During the product of manufacturer production, will not loosen and drop, range of application can not be limited, and can reduce use Cost.

Above example only have expressed preferred implementation of the present utility model, and it describes more concrete and detailed, But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for this For the those of ordinary skill in field, without departing from the concept of the premise utility, it is also possible to if making Dry deformation and improvement, as being combined the different characteristic in each embodiment, these broadly fall into this practicality Novel protection domain.
