Description
Technical field
The invention belongs to the category of connector terminal, a kind of disk spring washer that employs
Cylindricality terminal.
Background technology
In domestic distribution system, using most when connecting wire is column type terminal.The shortcoming of column type terminal
Being as the prolongation of use time, contact pressure can be gradually reduced, and contact resistance becomes larger.Cylindricality terminal connects
Touch pressure is gradually reduced what mainly both sides factor caused: 1, wire compacted in terminal is at pressure
Effect is lower occurs creep to make diameter diminish, and temperature is the highest, and creep is the most obvious；When 2, being given a shock, screw thread pair has
There is the trend of relative displacement.If able to utilize elastic washer the characteristic of elastic deformation to occur, just when compressing
Can effectively reduce because the problem that screw thread pair loosens or the pressure that causes of wire creep reduces.GB/T
2009.1 (equivalence IEC 884-1) the 26.4th section explicitly points out: " screw and rivet, no matter being electrically connected
Or it is mechanically connected, all should be locked, with anti-loosening and rotation "." spring pad is also indicated that in its note 1
Circle can play good locking effect ".Owing to column type terminal is to provide pressure with the end of screw, screw
Head does not stresses, so while know that spring washer can play good locking effect, the most never sees
Spring washer application on cylindricality terminal.
Number of patent application CN200820070902.2 discloses a kind of anti-loosening electric wire connecting junction, under pressing line frame
There is an elastic pressuring plate in portion, and described elastic pressuring plate can be exterior, it is possible to is made of one structure with pressing line frame.
A kind of binding post the most on sale, its main body is also column type terminal, outside pressing line frame
Having a circular stage clip upwards to lift pressing line frame below, power upwards is provided by the frame that insulate.
Above two examples are all good tries, but up to the present, the product going back neither one practical appears on the market.
Summary of the invention
It is an object of the invention to provide a kind of cylindricality terminal employing disk spring washer.
The solution of the present invention is as follows: a kind of cylindricality terminal employing disk spring washer, by housing pin,
Pressing line frame, disk spring washer, disk spring washer fixing device and conducting strip composition, in housing pin end
Lower section have a disk spring washer fixing device, in disk spring washer fixing device, have a dish
Spring washer.
One of preferably, described disk spring washer fixing device, is relative to pressure on conducting strip
More than at least three on tight screw end position upwards turn up part, all upwards turn up partial symmetry
Being distributed on a circumference, the center of circle of this circle is on the extended line of housing pin axis.
One of preferably, described disk spring washer fixing device sheet metal is made, fixing dress
The bottom put can be square, it is also possible to is circular, the external diameter being slightly larger in dimension than disk spring washer of bottom,
Periphery have upwards turn up part.
The using method of butterfly spring packing ring routine is to be enclosed within screw, and the interior warp of packing ring is more than the external diameter of screw,
The external diameter of packing ring is similar with the external diameter of screw head, and during screw tightening, its head flattens spring washer.Due to
Cylindricality terminal itself is to provide pressure with the end of screw, so spring washer cannot use the head at screw,
And can be only placed at the end of cylindricality terminal housing pin.Use electric current in the inside of the cylindricality terminal of below 32A
Space is the least, it is possible to putting the diameter about 6mm of the spring washer of pressing line frame into, thickness is at 0.3mm, bullet
The amount of spring gasket compression is at 0.15mm, and the least volume can provide the power of 630N, therefore, with this
The method of bright offer, in that context it may be convenient to disk spring washer is used on cylindricality terminal.
The present invention implements the simplest, it is not necessary to change structure and the use habit of existing column type terminal.
Owing to placed a disk spring washer in the end of housing pin, just the connection cylindricality terminal is former
Reason, from " being rigidly connected in elastic range " in past, becomes " the elastic connection in elastic range ".
The deformation of 0.15mm produced when disk spring washer is compacted, it is provided that elastic force fully meet GB/T2009.1
(equivalence IEC884-1) for the requirement of threaded terminal, it is sufficient to overcome owing to temperature and pressure causes
The adverse effect that metal creep brings, and effectively stop the trend of screw thread pair relative displacement when running into vibrations.

Fig. 2 a is circular base spring washer fixing device schematic diagram of the present invention；
Fig. 2 b is square base spring washer fixing device schematic diagram of the present invention；
Fig. 3 is the structural representation that disk spring washer is fixed on conducting strip；

Specific embodiments
Below in conjunction with accompanying drawing and embodiment, the present invention is described in detail
Embodiment one:
Referring to Fig. 1, Fig. 2, the head of housing pin 1 has the groove tightened for screwdriver, has in screw end
One disk spring washer fixing device 3, disk spring fixing device is folded up by being perpendicular to bottom surface 32
Part 31, be enclosed within the end of housing pin, the outside bottom fixing device is pressed on conducting strip, at dish
The inside of spring washer fixing device 3 placed a disk spring 4.When normally using, insulation crust is solid
Conducting strip and housing pin are determined so that conducting strip and housing pin the most do not have big in upper and lower, left and right
Displacement.By the rotation of housing pin, wire frame 2 can be up and down to adapt to the insertion of different-diameter wire,
And disk spring washer 4 can not be fallen out by fixing device 31 ends being locked in housing pin of turning up upwards.
When housing pin is tightened, by the interior energy of disk spring washer deformation storage, add cylindricality terminal anti-vibration
Ability and the ability of anti-metal creep, improve the reliability that cylindricality terminal uses.
Embodiment two:
Referring to Fig. 3, Fig. 4, on conducting strip 5, there is the dogleg section 51 upwards of more than at least 3,
Symmetrical being distributed on a circumference of these dogleg section upwards, this circumference be slightly larger in dimension than disk spring pad
The external diameter of circle, the center of this circle correspond to the axis of housing pin；Disk spring washer 4 is directly placed at conduction
On sheet 5, periphery is blocked by conducting strip dogleg section 51 upwards, no matter whether housing pin is tightened, and dish
Spring washer has all been limited in the end of housing pin reliably.After housing pin is tightened, disk spring pad
The upper edge of circle is close to the end face of housing pin, provides the biggest pressure by the least contact area, with
Time disk spring washer elastic deformation also improve anti-creep and anti-loosening ability.
