Brief description of the drawings

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:

Fig. 1 is that the master of a kind of two-sided direct insertion USB plug one preferred embodiment of the utility model looks schematic diagram.

In accompanying drawing, the mark of each parts is as follows: 1, upper casing, 2, lower casing, 3, upper plate, 4, lower plate, 5, tooth bar, 6, travelling gear, 7, the first hard contact, 8, the second hard contact, 9, the 3rd hard contact.

Embodiment

To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, the utility model embodiment comprises:

A kind of two-sided direct insertion USB plug, comprise housing and the joint that is arranged on described shell end, described housing comprises upper casing 1 and lower casing 2, described enclosure interior is provided with upper plate 3, lower plate 4 and travelling gear 6, in described upper plate 3 and lower plate 4, be equipped with the tooth bar 5 engaging with travelling gear 6, described travelling gear 6 drives upper plate 3 and lower plate 4 to move in opposite directions by tooth bar 5.

On the inwall of described upper casing 1 and lower casing 2, be equipped with one group of the 3rd hard contact 9, the bottom surface of the end face of described upper plate 3 and lower plate 4 is equipped with one group first hard contact 7 corresponding with the 3rd hard contact 9, and the end face of the bottom surface of described upper plate 3 and lower plate 4 is equipped with one group of second hard contact 8.

The second hard contact 8 in described upper plate 3 and lower plate 4 all with the first hard contact 7 internal communication, when work, two group of first hard contact 7 has and only has one group to be communicated with the 3rd hard contact 9.

Described one group of first hard contact 7, the second hard contact 8 and the 3rd hard contact 9 form by four hard contacts.

Between two group of the 3rd hard contact 9 of described upper casing 1 and lower casing 2, by the corresponding connection of wire reversed in order in housing, described wire is connected with the cable to device transmission signal.

The top of the bottom of described upper casing 1 and lower casing 2 is equipped with groove, and the two ends up and down of described travelling gear 6 are separately positioned in the groove of upper casing and lower casing.

The tooth bar 5 of described upper plate 3 and lower plate 4 lays respectively at the left and right sides of travelling gear 6.

Operation principle of the present utility model is as follows: in the time that USB joint inserts interface, always have one can be gone by the plate jacking in USB interface in upper plate 3 and lower plate 4.Suppose that lower plate 4 gone by jacking, the first hard contact 7 of lower plate 4 bottom surfaces just can separate with the 3rd hard contact 9, the at this time effect with travelling gear 6 by tooth bar 5, upper plate 3 will be out pushed, at this time the second hard contact 8 on upper plate 3 contacts with the contact in USB interface, the first hard contact 7 contacts with the 3rd hard contact 9 on upper casing 1, then connects altogether cable external on wire by upper casing 1 and upper casing 2 inside and carries out signal transmission.In like manner, can make upper plate 3 be gone by jacking when changing when a direction is inserted USB interface, repeat same process.
