Abstract
The utility model relates to a contactor, in particular to a contact unit used for being connected with a copper bar in a pluggable way on the contactor. The contact unit adopts the following technical scheme: the contact unit for the contactor is characterized in that one end of each contact finger is for connecting, the other end is for splicing, wherein the connecting end is provided with an arc surface, an annular clamping space is formed by the arc surface of the connecting end of each pair of contact fingers which are correspondingly arranged, and the splicing end of each contact finger is provided with a convex surface. With the adoption of the scheme, the novel contact unit overcomes the shortcomings of the prior art, the angle of the contact unit is convenient to adjust, and the contact unit can be fixedly connected with connecting pieces.
Description
Technical field
The utility model relates to a kind of connector, and particularly being used on the finger plug-in unit can plug the contact unit that is connected with copper bar.
Background technology
The effect of the contact unit of connector is that pull-out type parts in the low pressure draw out switchgear are electrically connected on the brace of busbar or other like.Contact unit of the prior art is made up of fingertip, U type compression spring etc. many, all only be provided with contact, an end on the engaging nail at each fingertip two ends, every pair of fingertip compresses two relative faces of two contact chips by the contact, end on it, and make these two engaging nails close mutually by the effect of the U type compression spring on the contact unit, keep impaction state to brace.The contact unit of said structure is because the surperficial contact area of U type compression spring and fingertip is big, and thermal conductivity is big, and the heat on the fingertip is diffused on the U type compression spring easily, so cause the elasticity capacity of U type spring to descend easily.
The applicant has applied for that in 2006 the patent No. is: the patent of 200610155613.3 " a kind of contact unit that is used for connector ", this patent has solved the problem of U type compression spring, but also there is following problem in it, 1, when installing, be not easy to adjust the angle that patches; 2, being arranged in the connector is that mode by pegging graft realizes that virtual connection or insecure takes place this mode easily.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of and can conveniently regulate the contact unit angle, and the novel contact unit that is used for connector that can well fixedly connected with connector.
For achieving the above object, the utility model adopts following technical scheme, a kind of contact unit that is used for connector, include two pairs or more fingertip, compression spring, spring(-supported) mount, wherein compression spring is a linear springs, the outside of fingertip respectively is provided with a compression spring, described spring(-supported) mount is provided with the socket for fingertip and compression spring grafting, the inwall of socket compresses with the compression spring formation and cooperates, the middle part of spring(-supported) mount is provided with fingertip and constitutes the latch that the location cooperates, it is characterized in that: an end of described every fingertip is a link, the other end is an inserted terminal, wherein link is provided with arc surface, and the arc surface of the link of the every pair of fingertip that is oppositely arranged forms a ring gripping space, and the inserted terminal of every fingertip is provided with crowning.
By adopting such scheme, we can be provided with cross section and be circular connector in connector, the ring gripping space of the link of contact unit fingertip can be socketed on the circular connector like this, can well prevent coming off of contact unit like this, in addition owing to be annular space and being connected of circular connector, so contact unit is adjusting angle arbitrarily, convenient pegging graft.
Further setting of the present utility model is: the two ends of the arc surface of described every fingertip link are respectively arranged with a salient point, the lateral surface of described every fingertip is provided with breach, scalariform is arranged to take in the two ends of this breach, described compression spring is arranged in the breach, and conflicts on the shoulder rank of fingertip in its two ends.
By adopting such scheme, the connector of the circle in the salient point that we can guarantee fingertip link arc surface and the connector closely contacts, good customer service the problem touched of virtual connection.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of the fingertip of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, a kind of contact unit that is used for connector, include two pairs or more fingertip 1, compression spring 2, spring(-supported) mount 3, wherein compression spring 2 is a linear springs, the outside of fingertip 1 respectively is provided with a compression spring 2, described spring(-supported) mount 3 is provided with the socket for fingertip 1 and compression spring 2 grafting, the inwall of socket compresses with compression spring 2 formations and cooperates, 3 middle parts of spring(-supported) mount are provided with fingertip 1 and constitute the latch 4 that the location cooperates, in the utility model embodiment, one end of described every fingertip 1 is a link 11, and the other end is an inserted terminal 12, and wherein link 11 is provided with arc surface 111, the cambered surface 111 of the link 11 of the every pair of fingertip 1 that is oppositely arranged forms a ring gripping space 112, and the inserted terminal 12 of every fingertip 1 is provided with crowning 121; Adopt such scheme, we can be provided with cross section and be circular connector in connector, the ring gripping space 112 of the link 11 of contact unit fingertip can be socketed on the circular connector like this, can well prevent coming off of contact unit like this, in addition owing to be annular space 112 and being connected of circular connector, so contact unit is adjusting angle arbitrarily, convenient pegging graft.
In the utility model embodiment, the two ends of the arc surface 111 of described every fingertip 1 link 11 are respectively arranged with a salient point 1111, like this, the connector of the circle in the salient point 1111 that we can guarantee fingertip 1 link 11 arc surfaces 111 and the connector closely contacts, well customer service the problem touched of virtual connection, the lateral surface of described every fingertip 1 is provided with breach 13, scalariform 131 is arranged to take in the two ends of this breach 13, described compression spring 2 is arranged in the breach 13, and conflicts on the shoulder rank 131 of fingertip in its two ends.
