Abstract
The utility model is related to no excitation disks to be cold-pressed tap switch, including sequentially connected operating and driving device and switch base, the switch base is internally provided with shaft, the shaft is equipped with moving contact, it is additionally provided with static contact on the switch base, one end of static contact is engaged with moving contact, the other end is protruding, the static contact is 3 groups of equidistant interval distribution, every group of static contact includes 1 bolt contact and several cold pressing contacts, and bolt contact with cold pressing contact, spacing between adjacent cold pressing contact is identical, also equidistant interval is distributed 3 bolt contacts, the cold pressing contact external part is equipped with for grafting and is cold-pressed the hole of fixed conducting wire.The utility model is using cold pressing contact and bolt contacts mates, the connection requirement of coarse circuit can be met, also can guarantee the connective stability of All other routes, and it is reasonable to be distributed spacing between each contact, interfere small, the excitation-free disk-shaped tapping switch of the utility model is applied widely.
Description
Technical field
The utility model is related to no excitation disks to be cold-pressed tap switch.
Background technology
The upper contact head of existing excitation-free disk-shaped tapping switch uses copper coin punching, when transformer tapping lead is connected thereto
It is fixed by bolts, it may cause lead to loosen in transformer transporting and operation in this way, cause poor contact, especially not
Adapt to full-sealed transformer needs.To overcome this defect, whether there is or not excitation bar-type tapping switch, to use lead cold in the market
Crimping structure, but its globality is bad, poor rigidity, cost is higher, and while being not suitable for compared with multi-line or thicker circuit uses.
Invention content
In order to solve the above technical problems, the purpose of this utility model is to provide one kind and is connected firmly, and convenient for coarse
Connection is cold-pressed tap switch without excitation disk.
To achieve the goals above, the utility model uses technical solution below：
No excitation disk is cold-pressed tap switch, including sequentially connected operating and driving device and switch base, the switch base
It is internally provided with shaft, the shaft is equipped with moving contact, and static contact is additionally provided on the switch base, and one end of static contact is touched with dynamic
Head engages, and the other end is protruding, and the static contact is 3 groups of equidistant interval distribution, and every group of static contact includes that 1 bolt touches
Head and several cold pressing contacts, and the spacing between bolt contact and cold pressing contact, adjacent cold pressing contact is identical, 3 bolt contacts
Also equidistant interval is distributed, and the cold pressing contact external part is equipped with for grafting and is cold-pressed the hole of fixed conducting wire.
Preferably：The hole of the cold pressing contact is complete tubular hole or semi-enclosed profiled holes.
Preferably：It is bolted between cold pressing contact and switch base.
The utility model can be met the connection requirement of coarse circuit, also can using cold pressing contact and bolt contacts mates
Ensure All other routes connective stability, and between each contact be distributed spacing it is reasonable, interference it is small, the utility model without exciter panel
Shape tap switch is applied widely.

The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
A kind of no excitation disk as depicted in figs. 1 and 2 is cold-pressed tap switch, including sequentially connected operating and driving device
1 and switch base 2, the switch base 2 is internally provided with shaft, and the shaft is equipped with moving contact, is additionally provided on the switch base 2 quiet
One end of contact, static contact is engaged with moving contact, and the other end is protruding, and the static contact is 3 groups of equidistant interval distribution,
Every group of static contact includes 1 bolt contact 4 and several cold pressing contacts 3, and bolt contact 4 and cold pressing contact 3, adjacent cold pressing contact
Spacing between 3 is identical, and also equidistant interval is distributed 3 bolt contacts 4, and 3 external part of cold pressing contact, which is equipped with, is used for grafting simultaneously
The hole of the fixed conducting wire of cold pressing.The hole of the cold pressing contact 3 is complete tubular hole or semi-enclosed profiled holes.It is cold-pressed contact 3
It is bolted between switch base 2.
It should be pointed out that above example is only the representative example of the utility model.The utility model can also there are many
Deformation.Every essence according to the utility model is to any simple modification, equivalent change and modification made by above example,
It is considered as belonging to the scope of protection of the utility model.
