Description

A kind of jack locking device of USB connector

Technical field

The utility model relates to the jack locking device of USB connector, is meant especially a kind ofly can effectively lock the jack of the USB connector of pulling, to prevent the locking device of transfer of data behavior improperly.

Background technology

Because the USB coffret has simple structure, efficiency of transmission height and technology maturation, therefore be widely used in computer or various 3C electronic product and linked, and USB connector also is indispensable assembly with the linking of relevant expanding device;

Yet, be accompanied by popularizing gradually of USB coffret application, the Portable memory storage of small size, high power capacity or other relevant data transmission device also have vigorous growth simultaneously, cause in the personal computer storage data by improper and possibility that steal fast heightens, and the discs that its harmfulness also is difficult for much larger than the disk sheet of traditional low capacity or store operation, but take a broad view of at present on the market, not seeing has the relevant locking device product that prevents the operation of USB coffret, thereby forms the big security breaches that it is used.

Because USB connector commonly used has above-mentioned shortcoming on using, the creator is the road at these shortcoming research improvement, has the utility model to produce finally.

Novel content

Main purpose of the present utility model is to provide a kind of jack locking device of USB connector, and it can effectively intercept being connected of USB connector and external device (ED), to prevent transfer of data behavior improperly.

Another purpose of the present utility model is to provide a kind of jack locking device of USB connector, and it has the fail safe in the use, can not cause damage to computer or relevant apparatus internal circuit fully.

Another purpose of the present utility model is to provide a kind of jack locking device of USB connector, and is very simple and easy on its structure, and easily very convenient on using.

The utility model is for reaching above-mentioned purpose and effect, its practiced technological means comprises: a housing, inside has accommodation space, one end is provided with corresponding Plug Division according to different USB connector jack shapes, and in regular turn is provided with at least one positioning port, a hollow-out parts and at least one window opening by this Plug Division to opposite side in this surface of shell; One locking bolt, be located in the accommodation space of this housing, the press section that is provided with a horizontal expansion in this locking bolt stage casing one side can outwards protrude out by the hollow-out parts of housing, and in the opposite side of this press section, the internal face that then can an elastic parts elasticity be resisted against housing, in addition distolaterally be provided with at least one location hook portion of extending in the same way, can outwards protrude out by the positioning port of housing with the press section in one of locking bolt, make this location hook portion can be with the stressed of press section in positioning port formation protrude out change in location; One number wheels, be to be sleeved on locking bolt periphery and adjacent and close and form by a plurality of digit wheels, with the activity of restriction locking bolt in housing, and each digit wheel periphery is provided with a plurality of location numbers, can outwards show via the window opening of housing, and wherein a permutation and combination can be removed restriction to the locking bolt activity.Thereby this device can be locked on the jack of USB connector, also can take off easily.

From the above mentioned as can be known, the jack locking device of the utility model USB connector can lock USB connector, forbids being connected, preventing with external device (ED) the effect of transfer of data behavior improperly, thereby has industrial practicality, novelty and progressive.

Embodiment

For detailed construction of the present utility model, application principle, effect and effect can be become apparent, hereinafter will cooperate appended graphicly, be described in detail below.

Fig. 1 is a structure decomposition map of the present utility model, by it with reference to Fig. 2,3 combination appearance figure and entire combination profile, can clearly find out, the utility model mainly comprises: housing 1, number wheels 2 and locking bolt 3 etc. are partly, this housing 1 can be by half housing 11 of two inner hollow, 12 relative be combined intos, be provided with corresponding Plug Division 13 according to different USB connector jack shapes at the one end, and be provided with at least one location 113 by this Plug Division in regular turn to opposite side in this housing 1 surface, one hollow-out parts 112 and at least one window opening 111, then be provided with a window in half housing, 12 surfaces and open 121 corresponding to this window opening 111, half housing, 12 inboards then are provided with a projection 122 corresponding to this hollow-out parts 112, number wheels 2 are adjacent and close and form by a plurality of digit wheel 21, be provided with a plurality of location numbers in each digit wheel 21 periphery, can be via the window opening 111 of housing 1,121 outwards show, each digit wheel 21 central authorities then is provided with a through hole 211, and in each through hole 211, be respectively equipped with a recess 212 corresponding to the diverse location number, locking bolt 3 is to be located in this housing 1, the one end is the through hole 211 through each digit wheel 21, and be provided with the press section 31 of a horizontal expansion in locking bolt 3 stage casings one side, can outwards protrude out by the hollow-out parts 112 of housing 1, opposite side in this press section 31 is provided with a location projection 32, can overlap unification elastic parts 321 (spring) and be resisted against projection 122 positions in the housing 1, then be provided with at least one location hook portion 33 of extending in the same way with press section 31 in another of locking bolt 3 is distolateral, this location hook portion 33 can outwards be protruded out by the positioning port 113 of housing 1.
