Abstract
The utility model relates to the technical field of electric power equipment connections and particularly relates to a large-throughflow spring contact longitudinal connector. The longitudinal connector comprises a static contact seat with an upward opening, two contact plates and four buffer springs; and each contact plate relative to the static contact seat is provided with two spring holes from top to bottom, one end of each buffer spring goes and is disposed in the corresponding spring hole, the other ends of the buffer springs go and are installed in the static contact seat, the two contact plates are symmetrically and vertically fixed to an inner-side bottom face of the static contact seat through double-head molybdenum nuts, an inner side of the each contact plate is provided with a circular groove capable of accommodating an enclosed annular square spring contact finger, and ends of the enclosed annular square spring contact fingers contact a moving contact inserted in the static contact seat. According to the large-throughflow spring contact longitudinal connector, contacts between the spring contact fingers and the moving contact and contacts between the spring contact fingers and the static contact seat are not concentrated into one point any longer and are linear contacts, contact areas between the spring contact fingers and the moving contact and contact areas between the spring contact fingers and the static contact seat are enlarged, and the throughflow capacity is greatly improved.
Description
Technical field
The utility model relates to power equipment interconnection technique field, specifically the longitudinal connector of a kind of large through-flow spring contact.
Background technology
In power equipment interconnection technique field, the connected mode of bus mainly contains plug-in type contact, Wedged contact, knife contact and dock contact etc. at present.Existing plug-in type contact, watchband-shaped contactor etc., have reciprocity and the poor limitation of interoperability when large activity surplus, is prone to the problem that tolerance is large.After assembling, dynamic and static contact due to without any buffer field, and easily there is the problems such as electrodynamical stability is poor, clamping stagnation.The position that spring touch finger will contact with dynamic and static contact is camber line, and the position that dynamic and static contact will contact with spring touch finger is straight line, so on the contact between spring touch finger and dynamic and static contact focuses on a bit, so just exist easily rub impaired, heat up high, the problem that through-current capability is poor.
Summary of the invention
The defect that the utility model exists in order to make up traditional connected mode, provides a kind of large through-flow spring contact longitudinal connector.
The utility model is to be achieved through the following technical solutions: the longitudinal connector of large through-flow spring contact, comprises opening up fixed contact pedestal, two touch panels, four buffer springs; The every piece touch panel relative with fixed contact pedestal from top to bottom has two spring eyes, one end of each buffer spring is placed through respectively in each spring eye, and the other end is threaded onto in fixed contact pedestal, two touch panels are respectively by symmetrical vertical being fixed in fixed contact pedestal inside bottom surface of double end molybdenum nut, every touch panel inner side all has the circular groove that can hold closed annular side spring touch finger, and the end of closed annular side spring touch finger contacts with the moving contact in being plugged in fixed contact pedestal.
The longitudinal connector of large through-flow spring contact described in the utility model, makes spring touch finger focus on a bit with contacting no longer of moving contact, fixed contact pedestal, but line contact, spring touch finger and moving contact, fixed contact pedestal contact area expand, and through-current capability improves greatly.Owing to being provided with buffer spring and touch panel between moving contact and fixed contact pedestal, solved the inhomogeneous problem of pressure, reduced moving contact and the fixed contact pedestal force of sliding friction when work, reduce heating rate, thereby further improved through-current capability.Due to the raising of through-current capability, and then improve electrodynamical stability, reduced tolerance, improved interoperability and the reciprocity of contact.
Accompanying drawing explanation
Fig. 1 is the structural representation of the longitudinal connector of large through-flow spring contact described in the utility model.
Fig. 2 is the end view of closed annular side spring touch finger.
In figure: 1-fixed contact pedestal, 2-touch panel, 3-buffer spring, 4-double end molybdenum nut, the closed annular side of 5-spring touch finger, 6-moving contact, 7-plain washer.
Embodiment
The longitudinal connector of large through-flow spring contact, comprises 2, four buffer springs 3 of 1, two touch panel of opening up fixed contact pedestal; The every piece touch panel 2 relative with fixed contact pedestal 1 from top to bottom has two spring eyes, one end of each buffer spring 3 is placed through respectively in each spring eye, and the other end is threaded onto in fixed contact pedestal 1, two touch panels 2 are respectively by symmetrical vertical being fixed in fixed contact pedestal 1 inside bottom surface of double end molybdenum nut 4, every touch panel 2 inner sides all have the circular groove that can hold closed annular side spring touch finger 5, and the end of closed annular side spring touch finger 5 contacts with the moving contact 6 in being plugged in fixed contact pedestal 1.
During concrete enforcement, between described double end molybdenum nut 4 and fixed contact pedestal 1, be arranged with plain washer 7.Further reduced moving contact 6 and fixed contact pedestal 1 force of sliding friction when work.
Further, the end of described moving contact 6 is fillet or chamfering.Be convenient to moving contact 6 and be easy to insert in fixed contact pedestal 1, in assembling process, moving contact 6 has enough activity surpluses.
