Abstract
The utility model discloses an improved structure of a USB (Universal Serial Bus) interface, which comprises a front casing, a main body rubber core, an upper casing and a lower casing, wherein the front casing is connected with the main body rubber core through a stuck point; the lower side of the front casing is buckled with the lower casing; the upper side of the front casing is buckled with the upper casing; a front casing leaf spring is arranged on the front casing and is also arranged outside the front casing; the front casing leaf spring is formed by reversely bending the front casing; the bending top end of the front casing leaf spring is a contact point between the front casing leaf spring and the upper and lower casings; and a feeding clearance is reserved between the tail end of the front casing leaf spring and the upper casing. The improved structure has the beneficial effects that: when an inner die is filled, the front casing is set to be opposite to the leaf spring so as to prevent the influence from unstable forming factors and ensure the conducted transmission of an earth signal when a product is used.
Description
Technical field
The utility model provides a kind of improvement structure of USB socket.
Background technology
At present, the structure of known USB3.0 MICRO-B PLUG fore shell ground connection is that conducting ground connection is carried out in forward bending of fore shell shell fragment and last lower casing assembly interference, and external mold encapsulate in recharging; When filled internal mold, because the destabilizing factor that is shaped, little when big when causing stuffing pressure, when stuffing pressure is excessive, melten gel from outside toward interior filling form one by force pressure, impact on the arm face of fore shell shell fragment, make shell fragment to lower compression, shell fragment contact point and the insulation of last lower casing are opened circuit.
To sum up, there is the bad hidden danger that opens circuit with last lower casing in the fore shell shell fragment of now knowing, the signal of earth-continuity when its structure can't guarantee the product use, and reverse new construction can guarantee the conducting between fore shell and last lower casing, and the signal of product earth-continuity can be transmitted smoothly.
The utility model content
The purpose of this utility model provides a kind of improvement structure of USB socket, and its reasonable in design during filled internal mold, reduces the influence that shell fragment is subjected to the moulding factor, guarantees the conducting transmission of ground signalling when product uses.
In order to reach above-mentioned purpose of design, the technical solution adopted in the utility model is as follows:
A kind of improvement structure of USB socket, comprise fore shell, main gel core, upper casing and lower casing, described fore shell links together by stuck point and main gel core, fore shell downside buckle lower casing, fore shell upside buckle upper casing, described fore shell is provided with the fore shell shell fragment, the fore shell shell fragment is arranged on the fore shell outside, described fore shell shell fragment is that the fore shell inverse bending forms, and the bending top of described fore shell shell fragment is the contact point of itself and upper casing and lower casing, is provided with the blanking clearance between the end of described fore shell shell fragment and the upper casing.
The beneficial effect of the improvement structure of USB socket described in the utility model is: when filled internal mold, make the reverse shell fragment of fore shell not influenced by the moulding destabilizing factor, guarantee the conducting transmission of ground signalling when product uses.

Among the figure: 1, fore shell; 2, main gel core; 3, back plug; 4, terminal; 5, grab; 6, upper casing; 7, lower casing; 8, fore shell shell fragment; 9, blanking clearance.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the utility model is described in further detail.
Shown in Fig. 1-4, the improvement structure of the described USB socket of the utility model embodiment, comprise fore shell 1, main gel core 2, upper casing 6 and lower casing 7, described fore shell 1 links together by stuck point and main gel core 2, fore shell 1 downside adopts button point screens mode buckle lower casing 7, fore shell 1 upside adopts button point screens mode buckle upper casing 6, described fore shell 1 is provided with fore shell shell fragment 8, fore shell shell fragment 8 is arranged on fore shell 1 outside, described fore shell shell fragment 8 is that fore shell 1 inverse bending forms, the bending top of described fore shell shell fragment 8 is the contact point of itself and upper casing 6 and lower casing 7, is provided with blanking clearance 9 between the end of described fore shell shell fragment 8 and the upper casing 6.
By back plug 3 fixed terminals 4 arranged side by side, described back is filled in 3 and is fixed on the main gel core 2 by grab 5 in the described main gel core 2.
Described fore shell shell fragment 8 adopts the inverse bending moulding, the position, blanking clearance prior to bending before, make the unsettled place, inverse bending shell fragment bottom of fore shell 1 be filled full glue.When assembly is finished when carrying out filled internal mold, when the melten gel of crunch is from outer to inner filled, at first contact is not elastic arm, fill full whole bottom but enter unsettled place, bending bottom by the blanking clearance, bent spring plate is supported, the gap does not appear and do not sunk by the powerful glue power of filling pressurising, thus the purpose that is insulated by glue.
This embodiment is a preferred embodiment of the present utility model, can not limit the utility model, and concrete every rights protection scope is defined by the claims.
Claims (2)
1. the improvement structure of a USB socket, comprise fore shell, main gel core, upper casing and lower casing, described fore shell links together by stuck point and main gel core, fore shell downside buckle lower casing, fore shell upside buckle upper casing, it is characterized in that: described fore shell is provided with the fore shell shell fragment, the fore shell shell fragment is arranged on the fore shell outside, described fore shell shell fragment forms for the fore shell inverse bending, the bending top of described fore shell shell fragment is the contact point of itself and upper casing and lower casing, is provided with the blanking clearance between the end of described fore shell shell fragment and the upper casing.
2. the improvement structure of USB socket according to claim 1 is characterized in that: described main gel in-core is by back plug fixed terminal arranged side by side, and described back plug is fixed on the main gel core by grab.
