Description

Prevent that plug from destroying the fixture of distortion
Technical field
The utility model relates to a kind of plug that prevents and destroys the fixture of distortion, refers to a kind of DC plug that is applicable to especially, and is available to prevent that O type terminal from destroying, the fixture of distortion.
Background technology
In Fig. 1, a kind of existing DC plug is disclosed, include an outer tube 10a and an O type terminal 20a who is made by electric conductor is constituted, be filled with insulator 30a between this O type terminal 20a and this outer tube 10a, make this O type terminal 20a and this outer tube 10a form two utmost points and separate shape, this O type terminal 20a is an O type body, is axially arranged with an elongated slot 21a in this O type terminal 20a upper edge, makes this O type terminal 20a be formed with two shell fragment 22a.So when being inserted in the DC plug to the terminal of inserting, this O type terminal 20a can envelope closely the terminal of inserting is contacted conducting.
But, this O type terminal 20a since two shell fragment 22a with slotting terminal is contacted, because of contact area greatly relatively makes its lifting surface area also bigger, and then influence its contact engaging and separating force and connect-disconnect life thereof.
See also Fig. 2, it is another kind of existing DC plug, this DC plug includes an outer tube 40a and and is made of the made O type terminal 50a of electric conductor, be filled with insulator 60a between this O type terminal 50a and this outer tube 40a, make this O type terminal 50a and this outer tube 40a form two utmost points and separate shape, this O type terminal 50a is an O type body, its leading section has been separated to form the rectangular shell fragment 51a of a plurality of sheets, the rectangular shell fragment 51a of these a plurality of sheets in position locates to bend inwards, and makes this O type terminal 50a form less internal diameter in its bending place.
Section portion is formed by the rectangular shell fragment 51a of a plurality of sheets with spigot being contacted before because of this O type terminal 50a, by the rectangular shell fragment 51a of these a plurality of sheets in the form of a ring with conducting that the terminal of inserting is contacted, so, can make whole contact engaging and separating force be scattered in the rectangular shell fragment 51a of a plurality of sheets respectively, make whole contact engaging and separating force little than steady change, and this each rectangular shell fragment 51a also can increase its connect-disconnect life, and be not easy elastic fatigue with all less to the area of slotting termination contact.
But, when the improper operation of user, when shaking to the terminal inserted, then should can contact the rectangular shell fragment 51a that this O type terminal 50a bends inwards originally to the terminal of inserting and outwards be out of shape, if when rectangular shell fragment 51a deflection is excessive, the destruction that then can cause O type terminal 50a, contact engaging and separating force is died down, not ability plug during use, and can cause rectangular shell fragment 51a with bad to the termination contact of inserting, can't reach the purpose of contact conducting really.
As from the foregoing, above-mentioned existing plug on reality is used, obviously exists inconvenience and shortcoming, and is necessary further to be improved.
Therefore, the present utility model people is kind at above-mentioned shortcoming, and the spy concentrates on studies and cooperates the utilization of scientific principle, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned shortcoming finally.
