In figure: 1, housing; 2, control piece; 3, bolt connection piece; 31, thread segment; 32, rotation section; 4, driving member; 5, opening; 6, the second teeth; 7, the first teeth.
Embodiment
Referring to figs. 1 through Fig. 2, a kind of D-SUB connector of the utility model embodiment is described further.
A kind of D-SUB connector, for realizing the information transmission between two electronic installation (not shown)s, comprise free-end electric connector and free-end electric connector is fixed on the locked component of fixed end electric connector, locked component includes at least two rotation sections 32, rotation section 32 includes rotation section 32 and thread segment 31, the driving member 4 that locked component also comprises control piece 2 and is sheathed on rotation section 32, control piece 2 and driving member 4 are connected and described driving member 4 and rotation section 32 are connected, control piece 2 driving member 4 that links all turns in the same direction described driving member 4 all rotation sections 32 of linking when rotating towards direction.
User gives a power source rotated to control piece 2, and control piece 2 driving member 4 that links rotates, and driving member 4 rotation section 32 of linking is rotated, and thread segment 31 to proceed on fixed end electric connector and free-end electric connector is fixed on fixed end electric connector by rotation section 32.(bolt connection piece 3 of D-SUB connector common on the market is all set to two, so the bolt connection piece 3 of the utility model D-SUB connector is preferably two, so that suitable with corresponding free-end electric connector).
Described driving member 4 is in band shape and inner and outer is equipped with the first teeth 7, rotation section 32 and control piece 2 are all in cylindric, the excircle of rotation section 32 and control piece 2 is provided with the second teeth 6 be meshed with driving member 4 first teeth 7, driving member 4 is sheathed on rotation section 32 excircle, the teeth of rotation section 32 are that gear coordinates with the inner side teeth of driving member 4, the teeth of control piece 2 are that gear coordinates with the outside teeth of driving member 4, control piece 2 driving member 4 that links rotates towards a direction, driving member 4 links rotation section 32 all towards equidirectional rotation, control piece 2 and rotation section 32 are in same rotation period, accurately to control rotation section 32 and control piece 2.
As another kind of execution mode, described driving member 4 is in band shape and outside is provided with the first teeth 7, rotation section 32 and control piece 2 are all in cylindric, the excircle of rotation section 32 and control piece 2 is provided with the second teeth 6 be meshed with driving member 4 first teeth 7, driving member 4 is connected to rotation section 32 excircle, control piece 2 is connected to the excircle of rotation section 32, the teeth of rotation section 32 are that gear coordinates with the outside teeth of driving member 4, the teeth of control piece 2 are that gear coordinates with the outside teeth of driving member 4, control piece 2 driving member 4 that links rotates towards a direction, driving member 4 links rotation section 32 all towards equidirectional rotation.
Again as another kind of execution mode, the driving member 4 of this D-SUB connector is preferably with the cingulum of teeth, also can be chain, driving member 4 is connected in the form of a ring by each chain link, rotation section 32 and control piece 2 are all in cylindric, on the excircle of rotation section 32 and control piece 2, equal indentation is arranged and suitable with chain, chain is sheathed on rotation section 32 excircle, rotation section 32 and the inner side of chain are that chain drive coordinates, control piece 2 and teeth outside chain are that chain drive coordinates, control piece 2 chain that links rotates towards a direction, chain interlock rotation section 32 all towards equidirectional rotation (because the design of chain in narrow space is comparatively complicated, the engagement fit of the teeth of driving member 4 arranges and makes control more accurate, this D-SUB connector does not adopt chain transmission mode, other embodiments about chain are not just describing in detail).
