Abstract
The utility model belongs to the technical field of the connection of power equipment, and particularly relates to a plane electric connector of an axial spring. The existing power equipment connecting equipment can not meet required movement allowance when a bus bar is connected, and can not meet the large-tolerance problem in the aspect of assembling and the shaking problem after the assembling. A U-shaped fixed contact head, a movable contact head and an axial inclined-ring spring are arranged on the plane electric connector, the end of the movable contact head is designed to be a circular angle or a chamfer angle, the axial inclined-ring spring is arranged in an installing groove of an inner cavity of the fixed contact head, and the inclined-ring spring is under a compressing state due to axial force. Therefore, the structure assembling with large errors when the plane electric connector is machined or large movement allowance after the plane electric connector is assembled can be effectively met, the reliable connection can be realized, and the larger through-current capability can be guaranteed.
Description
Technical field
The utility model belongs to power equipment interconnection technique field, is specifically related to a kind of axle spring plane electric connector.
Background technology
Now in the power equipment industry; The main bus connected mode of using has Mume flower contact, duck-beak type contact, watchband contact, also has oblique coil spring interconnection technique, and wherein tiltedly the interconnection technique of coil spring is low with its processing request, cost is low, big characteristics of connection reliability Senior Three and be widely used in the power equipment industry.But, in the present power equipment, as in, low-tension switch cabinet is owing to be to adopt the panel beating mode to process mostly, is not very high at the precision everyway; And it is common than the long concentricity that also is difficult to the dynamic and static contact of assurance in High-Voltage Electrical Appliances such as the combined electrical apparatus owing to moving contact; So need very big activity surplus in the time of will requiring the connection of switch; Could satisfy the high tolerance problem aspect assembling like this; And the vibration problems after assembling, and aspect the activity surplus that existing Mume flower contact, watchband fingertip all connect at bus significant limitation is being arranged.
Summary of the invention
The purpose of the utility model provides a kind ofly to be had big activity surplus and connects reliable axle spring plane electric connector.
The technical scheme that the utility model adopted is:
A kind of axle spring plane electric connector includes fixed contact and moving contact, it is characterized in that:
Described fixed contact is the U-shaped fixed contact, and moving contact is arranged in the U-lag of fixed contact;
Two walls are provided with annular mounting groove in the U-lag, respectively are provided with axially tiltedly coil spring in the groove.
Described moving contact top is provided with fillet or chamfering.
The utlity model has following advantage:
The utility model has guaranteed between the dynamic/static contact still to be the enough activity surpluses of fore-and-aft direction at above-below direction no matter; So the bus that is connected with the plane moving contact also has very big activity surplus; Can solve the high tolerance problem aspect assembling; And the vibration problems after assembling, guaranteed simultaneously well to contact with elastomeric element after the plane moving contact inserts the plane fixed contact; In conducting process, dull and stereotyped fixed contact adopts axially oblique coil spring to be connected with dull and stereotyped moving contact, the above-below direction symmetry; The moving contact front end adopts fillet or chamfering; So moving contact is easy to insert fixed contact during assembling, especially under blind spot assembling situation, installs comparatively easy.
Description of drawings
Fig. 1 is dynamic/static contact assembling sketch map.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, the axially oblique coil spring of 1-, 2-fixed contact, 3-moving contact, 4-mounting groove.
Embodiment
Below in conjunction with embodiment the utility model is carried out detailed explanation.
The utility model includes fixed contact 2 and moving contact 3.Fixed contact 2 is the U-shaped fixed contact, has plate shaped two walls parallel to each other, and two walls are provided with annular mounting groove 4 in the U-lag, respectively is provided with an axially oblique coil spring 1 in the groove.Moving contact 3 is arranged in the U-lag of fixed contact 2, and moving contact 3 is a tabular, and the top is provided with fillet or chamfering, can insert fixed contact 2 more swimmingly.After in the U-lag of moving contact 3 insertion fixed contacts 2; With two axially tiltedly coil springs 1 near; And make axially tiltedly coil spring 4 receive axial compressive force to be in compressive state; When the internal chamber wall distance of moving contact 3 and fixed contact 2 more hour, axially tiltedly the decrement of coil spring 1 is big more, moving contact 3 with axially tiltedly coil spring 1, that fixed contact 2 is connected with the contact of axial oblique coil spring 1 is good more.
When moving contact 3 centering in the inner chamber of fixed contact 2 is not under the good situation, because the fillet or the chamfering of moving contact 3 ends, moving contact 3 also can inject fixed contact 2 easily.In the assembling process, moving contact 3 has move place, and the inner distance of moving contact 3 thickness and fixed contact 2 differs big more, and this unsteady distance range is also big more, but the most very much not should surpass axially the tiltedly elastic compression amount of coil spring 1 and fixed contact 2 inner chambers.
Claims (2)
1. an axle spring plane electric connector includes fixed contact (2) and moving contact (3), it is characterized in that:
Described fixed contact (2) is the U-shaped fixed contact, and moving contact (3) is arranged in the U-lag of fixed contact (2);
Two walls are provided with annular mounting groove (4) in the U-lag, respectively are provided with axially tiltedly coil spring (1) in the groove.
2. a kind of axle spring according to claim 1 plane electric connector is characterized in that:
Described moving contact (3) top is provided with fillet or chamfering.
