Description

A kind of adapter

Technical field

The utility model relates to the communications field, relates in particular to a kind of adapter.

Background technology

The computer hardware develop rapidly, ancillary equipment is increasing, keyboard, mouse, modulator-demodulator, printer, scanner become already people the product be familiar with very much, products such as digital camera, MP3 walkman also enter people's life more and more sooner.Different equipment will realize connecting a kind of special interface of needs.USB (Universal Serial Bus, USB) is an interface that makes the computer peripheral equipment connect standardization, unification.USB also supports hot plug, that is to say under the situation of start, also can connect safely or disconnects USB device, reaches real plug and play.

In order to realize the switching between different USB interface such as Mini USB and generic USB interface, designed the multiple switching scheme of USB in the prior art, make things convenient for subscriber equipment to insert PC.

USB switching scheme in the prior art one, two USB heads directly connect by cable, reach to prolong to insert purpose.

As shown in Figure 1, be the schematic diagram of the switching of the USB in the prior art two scheme, adopt straight inserting head to realize switching.As shown in Figure 1, two USB heads connect by very short cable, the coated outside plastic cement, and two statures can not relatively move.

In implementing process of the present utility model, the designer finds that there is following shortcoming at least in prior art:

Cable in the prior art one does not have support force, can't bear the weight of equipment, and cable is long, carries inconvenience.Can not relatively rotate owing to two statures in the prior art two, if connected equipment is long, meeting length very after inserting, not only inconvenience but also danger close by straight inserting head.

Described rotating shaft comprises housing, rotary head, middleware, spring; Wherein, the upper surface of described housing has a perforate, described rotary head is partly protruded the upper surface of described housing by described perforate, and the part that described rotary head is arranged in described housing meshes with described middleware, and described spring is installed between the lower surface of described middleware and described housing.

Compared with prior art, the utility model embodiment has the following advantages at least:

By using rotating shaft, guarantee that adapter can reliably rotate, have certain torsion, can revolve and stop.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in detail.

The utility model embodiment provides a kind of adapter, comprising:

First housing, first USB interface, cable, rotating shaft, second housing and second USB interface; The second housing front end has an axle with holes;

First housing has two location notchs, and rotating shaft is installed on first location notch, and the axle with holes of the second housing front end is installed on second location notch, and first USB interface is installed on first housing, and second USB interface is installed on second housing; Cable connects first USB interface and second USB interface by axle with holes;

Rotating shaft comprises housing, rotary head, middleware, spring; Wherein, the upper surface of housing has a perforate, and rotary head is partly protruded the upper surface of housing by perforate, and the part that rotary head is arranged in housing meshes mounting spring between the lower surface of middleware and housing with middleware.

Rotation adapter by using the utility model embodiment to provide can guarantee that adapter reliably rotates, and has certain torsion, can revolve and stop.

The utility model embodiment provides a kind of adapter, and as shown in Figure 2, changeing USB A with Mini USB A is that example describes.

The structure of this adapter comprises as shown in Figure 2: first housing 21, USB A 22, cable 23, rotating shaft 24, the second housings 26 and Mini USB A 27; The second housing front end has an axle 25 with holes.

First housing 21 has two location notchs, and rotating shaft 24 is installed on first location notch, and the axle 25 with holes of second housing, 26 front ends is installed on second location notch, and USB A 22 is installed on first housing 21, and MiniUSB A 27 is installed on second housing 26; Cable 23 connects USB A 22 and MiniUSB A 27 by axle 25 with holes.

During use, first housing 21 and second housing 26 are rotated by rotating shaft 24, axle with holes 25, and revolution crosses 45 when spending, because revolving of rotating shaft 24 stop function and can realize that revolving of adapter stop, and have certain spring torsion.The overall schematic of the adapter that Fig. 3 provides for the utility model embodiment, this adapter can make progress, revolve respectively downwards and turn 90 degrees, and revolution is crossed 45 degree and can be realized revolving stopping.

The utility model embodiment also provides a kind of rotating shaft, shown in Fig. 4 a, Fig. 4 b, comprising: housing 41, rotary head 42, middleware 43, spring 44;

Wherein, the upper surface of housing 41 has a perforate, and rotary head 42 is partly protruded the upper surface of housing 41 by this perforate, and rotary head 42 is arranged in the part and middleware 43 engagements of housing 41, mounting spring 44 between the lower surface of middleware 43 and housing 41.

Middleware 43 and spring 44 can only can not rotate along the spring axial motion in housing; Rotary head 42 can be rotated.Rotary head 42 has the same structure of similar gear with middleware 43, shown in Fig. 4 b.When rotary head 42 is rotated because middleware can not rotate, it can only in the contractive pressure spring that contracts, when rotary head 42 with after the tooth top of middleware 43 contacts, under the effect of spring, can slip over tooth top, enter the region of engagement of rotary head 42 and middleware 43.

When using this rotating shaft, stationary housing 41, rotation rotary head 42.When rotary head 42 is rotated because middleware 43 can not rotate, can only in the contractive pressure spring 44 that contracts.Rotary head 42 turns over 45 when spending, and rotary head 42 with middleware 43 engagement takes place, and realizes revolving stopping; Simultaneously, because spring 44 is compressed generation deformation, make rotating shaft have certain torsion.

By the adapter that adopts the utility model embodiment to provide, guarantee that adapter reliably rotates, have certain torsion, can revolve and stop; Because the reliability of rotating shaft than higher, can satisfy the requirement of rotation reliability testing.

In a word, the above is preferred embodiment of the present utility model only, is not to be used to limit protection range of the present utility model.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
