Abstract
The utility model relates to a contact pin structure of connector for motor train set or subway, which is composed of a pair of fixed contact pin component and a mobile contact pin component, wherein the fixed contact pin component is composed by connecting a pressing line part, a fixed contact pin and a fixed contactor in turn, the mobile contact pin component is composed by connecting a pressing line part, a mobile contact pin, a spring, a pressing rod and a mobile contactor in turn, and the mobile contactor is contacted with the fixed contactor. The utility model has the advantages that the contact point of the contact pin structure is pressed by the spring to keep compression state, thereby confirming stable contact in the high speed operation of motor train set or subway.
Description
Technical field
The utility model relates to a kind of connector pin structure, in particular to the connector pin structure that is used for motor train unit or subway.
Background technology
Existing connector pin structure nearly all be based on the down design of environment that connector is in static or low speed, thereby the fixed-site of the contact pin structure of connector when connecting is constant.And the speed of service of motor train unit or subway is very high, thereby vibration is also very big, the contact pin structure of the connector that original adaptation environment static or low speed designs down can not adapt to this high velocity environment, when motor train unit or subway run up, cause the junction of connector radial and axial offset deviation to occur, cause the loose contact of connector easily.
The utility model content
For the stable connection of the connector that improves motor train unit or subway, the utility model provides a kind of connector pin structure, can keep the stable connection of connector under environment at a high speed.
The technical solution adopted in the utility model is: a kind of connector pin structure, form by a pair of motionless contact pin assembly and moving contact pin assembly, motionless contact pin assembly by line ball position, motionless contact pin and not moving contact connect to form successively, moving contact pin assembly is connected to form successively by line ball position, moving contact pin, spring, depression bar and moving contact, described moving contact and not moving contact contact.
The beneficial effects of the utility model are: dock structure contact pin is to utilize spring pressure to make arc surface to pressing conduction, a pair of contact pin is divided into moving contact pin assembly and motionless contact pin assembly, the moving contact of moving contact pin assembly can move vertically, the contact point of this structure is because be subjected to the pressure of spring, all be in impaction state always, can when motor train unit or subway run up, still can guarantee stable contact.
Description of drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals: motionless plug in component 1, motionless contact pin 11, line ball position 12, not moving contact 13, not moving contact conducting surface 14, moving contact pin 21, line ball position 22, moving contact 23, spring 24, depression bar 25, moving contact conducting surface 26.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further, but embodiment should not be construed as limitation of the present invention.
As shown in Figure 1, the connector pin structure, form by a pair of motionless contact pin assembly 1 and moving contact pin assembly 2, motionless contact pin assembly 1 by line ball position 12, motionless contact pin 11 and not moving contact 13 connect to form successively, moving contact pin assembly 2 is connected to form successively by line ball position 22, moving contact pin 21, spring 24, depression bar 25 and moving contact 23, described moving contact 23 and not moving contact 13 contact.The pressure of spring 24 passes to moving contact 23 by depression bar 25, can guarantee that contact point still keeps in touch when axial direction is subjected to displacement.
The not moving contact conducting surface 14 at described not moving contact 13 tops is the circular arc concave surface, and the moving contact conducting surface 26 at described moving contact 23 tops is the arc convex surface with 14 couplings of moving contact conducting surface not.
The content that is not described in detail in the utility model specification belongs to this area professional and technical personnel's known prior art.
