Features of spring contact fingers


Release time:

2022-06-07

It is composed of a ring-shaped spring connected end to end; in the prior art, the contact finger of the spring is installed in the conductive shaft groove, and the spring is easy to break and fall off; after the spring contact finger falls off at the welding place, it is easy to cause gas-insulated metal-enclosed switchgear Safety accident, then, let's learn about the characteristics of the lower spring contact finger!

Features of spring contact fingers

The spring contact finger is a safe spring contact finger that stays on the conductor after being broken and does not fall off to ensure that other insulators in the closed container remain unchanged and move safely. It belongs to the technical field of electrical equipment. The spring contact finger is a component used to flexibly connect two conductors and consists of a ring-shaped spring connected end to end. In the prior art, the contact finger of the spring is installed in the conductive shaft groove, and the spring is easy to break and fall off; after the spring contact finger falls off at the welding place, it is easy to cause the safety accident of the gas insulated metal enclosed switchgear. Then, let's understand the characteristics of the lower spring contact finger together!

In order to overcome the shortcomings of the prior art, the spring contact finger provides a safe spring contact finger that does not stay on the conductor and fall off even after breaking, and ensures the constant and safe operation of other insulators in the closed container. The spring contact finger is a spring contact finger including a ring-shaped metal spring and a locking ring. The locking ring is arranged inside the ring-shaped metal spring, and the locking ring is fixedly arranged on the inner wall of the ring-shaped metal spring. By applying the above technology, the utility model Compared with the prior art, the spring contact finger is composed of a ring-shaped metal spring that has been successfully welded, and a circular metal or non-metal lock ring is configured inside the spiral ring of the spring, after the annular spring is broken, the spring can extend straight without separating from the conductive shaft, and the lock ring can prevent an explosion caused by a short circuit fault between other electrical conductors of the gas-insulated metal-enclosed switchgear.


The spring contact finger is a ring-shaped metal spring that is smoothly welded. A circular metal or non-metal locking ring is arranged inside the spiral ring of the spring. After the ring-shaped spring is broken by the locking ring, the spring can be prevented from extending in a straight line and falling off from the conductive shaft, and the explosion caused by short circuit fault between other conductors of the gas-insulated metal hermetic switchgear can be prevented, there is no limitation on the protection scope of the utility model, and the technical scheme formed by equivalent transformation or equivalent replacement, or the moving mode of the relative flat plate described in the utility model, are all within the protection scope of the utility model.


Features of spring touch fingers:


1. The spring contact finger is characterized in that it comprises an annular metal spring and a locking ring; the locking ring is arranged inside the annular metal spring.


2. The spring contact finger is characterized in that the locking ring is fixedly arranged on the inner wall of the annular metal spring.


The spring contact finger includes a ring-shaped metal spring and a lock ring; the lock ring is arranged inside the ring-shaped metal spring; the spring contact finger is a ring-shaped metal spring that has been successfully welded, and a circular metal or metal is placed inside the spring coil. The non-metal lock ring can prevent the spring from extending linearly and falling off from the conductive shaft after the ring spring is broken, an explosion caused by a short-circuit fault between other electrical conductors of the gas-insulated metal-enclosed switchgear can be avoided.


The above introduction is the characteristics of the spring touch finger, if you need to know more, please feel free to contact us!
