The data of offering discloses a kind of bus tie [application number：201510345067.3；Application publication number：CN106329167A],
Including insulating sleeve in a tubular form and the contact tube in insulating sleeve, the both ends of contact tube have for clamping bus
Contact, contact have multiple notches, and multiple notches are evenly distributed on contact, and multiple notches prolong along the length direction of contact tube
It stretches.
Above-mentioned bus tie on contact by being arranged notch, when the outer diameter for bus occur is greater than or slightly larger than contact
Internal diameter when, contact can be expanded outwardly radially, thus realize with the connection of bus so that easy to connect, but work as bus
When having certain eccentric with contact tube, the contact of contact tube is difficult to receive bus, causes to be displaced again two switchgears, make
Contact tube and the setting of bus almost coaxial are obtained, could be connected so smoothly, so the convenience of connection still needs to improve, it is in addition conductive
Pipe is hollow tubular, and current-carrying capability is still not ideal enough.
Summary of the invention
The purpose of this utility model is to provide a kind of mother easy to connect for the above-mentioned problems in the prior art
Line connects core.
The purpose of this utility model can be realized by the following technical scheme：A kind of bus connects core, including connector and
Contact positioned at connector both ends, the connector is in the form of a column and the both ends of connector all have axially projecting connector,
For the contact by several pieces of contacts around forming and contact is cylindrical in shape, the both ends lateral surface of the contact all has mounting groove
And winding is provided with the spring that elastic force tightly touches contact mutually in mounting groove, the medial surface of the contact inner end has for even
The concave surface that connector is caught in, the medial surface of contact outer end have the cambered surface of a circle radially protruding.
In a kind of above-mentioned bus connection core, the connector has the linkage section being coaxially disposed with connector, institute
The concave surface stated is spherical surface, and the connector is in bulb shape or in the form of annular discs.Linkage section, which provides, allows column pitch, facilitate contact around
Connector deflection, the setting of connector and concave surface is so that deflection process is smooth and deflection angle is larger, to facilitate connection.
In a kind of above-mentioned bus connection core, the connector is solid red copper part.Connector carrying electricity in this way
The ability of stream is good, and current-carrying capacity is big.
In a kind of above-mentioned bus connection core, the contact is copper sheet and surface has silver coating, the touching
The thickness of piece is at least 3.5mm.The current-carrying capacity of contact in this way is big and good conductivity.
In a kind of above-mentioned bus connection core, the quantity of spring is two in the mounting groove.Elastic force is good in this way makes
It obtains contact and remains that the trend of tubular is strong, long service life.
Compared with prior art, the contact outer end guiding performance of this bus connection core is good, is inserted into convenient for bus, contact inner end can
It is deflected around connector, there are in the case where certain installation error, remaining to be inserted into for bus, so that easy to connect, and current-carrying capacity
Greatly, good conductivity.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As depicted in figs. 1 and 2, this bus connect core retainer plate in silica gel sheath comprising connector 1 and be located at 1 liang of connector
The contact 2 at end, connector 1 is in the form of a column and the both ends of connector 1 all have axially projecting connector 11, and contact 2 is touched by six pieces
Around forming and contact 2 is cylindrical in shape, the both ends lateral surface of contact 2 all has to be wound in mounting groove 22 and mounting groove 22 and mention piece 21
For the spring 3 that elastic force tightly touches contact 21 mutually, the medial surface of 2 inner end of contact has the concave surface 23 being caught in for connector 11,
The medial surface of 2 outer end of contact has the cambered surface 24 of a circle radially protruding.
Contact 2 is surrounded by contact 21 in this bus connection core forms, when the outer diameter for bus occur is greater than or slightly larger than contact 2
Internal diameter when, 21 outer end of contact can radially expand outwardly, and cambered surface 24 plays guiding role, facilitate bus insertion contact 2 in,
