Abstract
The utility model relates to an outer connector for a tubular busbar. The outer connector comprises a connector main body. Connecting grooves are disposed at two ends of the connector main body, so the connector main body has an H-shaped cross section. A plurality of cavities is disposed on the inner side of the periphery of the connector main body, and a canted coil spring is arranged in each cavity. Positioning sleeves are arranged at two ends of the connector main body in a circumferential manner, a moving contact is disposed inside each positioning sleeve, and each positioning sleeve is positioned outside each corresponding cavity. Each cavity is divided into an upper cavity and a lower cavity, wherein the upper cavity has a cross section shaped like an isosceles triangle and the lower cavity has a cross section shaped like a rectangle. The outer connector is convenient to install on a site, is low in contact resistance, can meet demands of heavy current transmission, and has a good heat dissipation property.
Description
Technical field
The utility model relates to a kind of connector, particularly a kind of outconnector that connects tubular bus.
Background technology
Tradition tubular bus outconnector machining accuracy is high, cost improves, bus outconnector with tubular be that face contacts, face contact resistance is large, can not carry out by variations in temperature, causes bus axial dimension compensating for variations.Owing to there being the existence of most advanced and sophisticated and bolt, surface field belongs to severe non-uniform electric field, and surface field intensity improves thus, surface breakdown lower voltage.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of tubular bus outconnector for above drawback, and scene is easy for installation, contact resistance is little, meet large electric current conveying, good heat dissipation.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of tubular bus outconnector, comprise connector body, wherein, described connector body two ends are provided with link slot, make connector body cross sectional shape become H shape, described connector body inner circumferential is evenly provided with some cavitys, in described cavity, be provided with fingertip spring, described connector body two ends are circumferentially with positioning sleeve, in positioning sleeve, be provided with moving contact, described positioning sleeve is positioned at the outside of described cavity, and described cavity is divided into upper plenum and lower cavity, described upper plenum cross sectional shape is isosceles triangle, and the cross sectional shape of described lower cavity is rectangle
Above-mentioned a kind of tubular bus outconnector, wherein, described moving contact cross sectional shape is rectangle, its top is circular arc.
The beneficial effects of the utility model are:
1. required precision is not high, and mismachining tolerance and rigging error are had to larger adaptability, reduces production costs, and is more suitable for large-scale production.
2. contact point is many, contact resistance is little, good heat dissipation, good conductivity, meet that large electric current is carried, moving and thermal stability is high, reduces the wastage.
3. safe and reliable, long service life in service, on-the-spot easy for installation, reduce installation cost.
4. improve bus junction surface corona voltage, reduce junction surface field intensity.
5. between conductor and conductor, backlash compensation bus causes that by variations in temperature length dimension changes, connector or a compensator thus.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, a kind of tubular bus outconnector, comprise connector body 1, wherein, described connector body 1 two ends are provided with link slot 2, make connector body 1 cross sectional shape become H shape, described connector body 1 inner circumferential is evenly provided with some cavitys 3, in described cavity 3, be provided with fingertip spring 4, described connector body 1 two ends are circumferentially with positioning sleeve 5, in positioning sleeve, be provided with moving contact 6, described moving contact 6 cross sectional shapes are rectangle, its top 61 is arc-shaped structure, described positioning sleeve 5 is positioned at the outside of described cavity 3, described cavity 3 is divided into upper plenum 31 and lower cavity 32, described upper plenum 31 cross sectional shapes are isosceles triangle, the cross sectional shape of described lower cavity 32 is rectangle.
As shown in Figure 2, in the time that tubular bus 7 inserts respectively connector two ends, the fingertip spring 4 in connector is under pressure respectively and a bit the contacting of 2 points of upper plenum wall, lower cavity wall, and forms a galvanic circle, is communicated with the tubular bus at two ends.
As shown in Figure 3, moving contact and positioning sleeve design are very important, should ensure the insulation between moving contact and conducting rod, ensure that again conducting rod slip is flexibly because positioning sleeve design is bad and stuck or increase kinetic friction force, this just requires the external diameter maximum (d of tubular bus 7
1max) be less than positioning sleeve and pack the internal diameter minimum d after groove into
2min, guarantees that conductors slide is flexibly without jam phenomenon, and positioning sleeve packs the internal diameter maximum d after movable contact block groove into
2max must be less than connector body internal diameter minimum d
3min, guarantees that tubular bus isolation because of positioning sleeve in static work or operational movement process do not collide with connector body, otherwise can cause shunting accident.
Here description of the present utility model and application is illustrative; not want scope of the present utility model to limit in the above-described embodiments; therefore the utility model is not limited by the present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in the utility model protection range.
Claims (2)
