Abstract
The invention discloses a single-pole single-throw vacuum relay which comprises a ceramic vacuum chamber and two contact point poles which penetrate through the side walls of the vacuum chamber in a sealed manner, a contact piece is positioned on one end of one contact point pole, which faces the inside of the vacuum chamber, a contact point is respectively arranged on one end of the other contact point pole, which faces the inside of the vacuum chamber, the ceramic vacuum chamber is in the shape of an open cylinder, a slotted contact point is arranged on one contact point pole and contacts one end of the contact piece in a positioned manner, a contact point is arranged on the other contact point pole, a ceramic point corresponding to the contact point is formed on the inner wall of the vacuum chamber, the other end of the contact point is located between the contact point and the ceramic point, namely, a traditional single-pole double-throw vacuum relay layout is formed among the contact piece, the contact point and the ceramic point. The structure basically remains the appearance of the same level of single-pole double-throw vacuum relay, and the inner structure of a ceramic component is redesigned, so that a single-pole double-throw vacuum relay can be rapidly improved to the single-pole single-throw vacuum relay.
Description
Technical field
The present invention relates to a kind of relay, especially a kind of single-pole single-throw(SPST vacuum relay of only establishing two contact point bars.
Background technology
At present, existing circular single-pole double throw (three contacts) relay is ripe vacuum relay on the market, its typical contact structure such as Fig. 1, keeping essentially identical technical conditions and installing under the prerequisite of profile, design single-pole single-throw(SPST relay (two contact relays), be the interference of avoiding unnecessary contact to cause, the general method that unnecessary contact is shortened or removed that adopts, its design or the mechanism that can not avoid the electric field of unnecessary contact to disturb or must adopt other control armature motion fully, thereby the negative effect that brings other.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of single-pole single-throw(SPST vacuum relay, can realize fast the single-pole double throw relay being improved to the purpose of single-pole single-throw(SPST relay.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of single-pole single-throw(SPST vacuum relay, comprise ceramic vacuum chamber and the plurality of touch points bar that seals on the sidewall that is located in vacuum chamber, be positioned with contact chip on the end of one of them contact point bar in vacuum chamber, the end of all the other contact point bars in vacuum chamber is provided with contact point, the ceramic vacuum chamber is the open circles tubbiness, contact point bar on the described sidewall that is located in vacuum chamber is two, a contact point bar is provided with the fluting contact point, described contact chip one end of this fluting contact point location contact, another contact point bar is provided with contact point, on the inwall of this vacuum chamber to the ceramic point that is formed with a corresponding described contact point, the described contact chip other end between described contact point and pottery point, promptly described contact chip, form traditional single-pole double throw vacuum relay layout between contact point and the pottery point.
As a further improvement on the present invention, described pottery point is the formation that extends internally of the sidewall of ceramic vacuum chamber.
As a further improvement on the present invention, described pottery point extends to form towards opening part for bottom surface, ceramic vacuum chamber.
The invention has the beneficial effects as follows: the present invention adopts two contact point bar structures, substantially the profile that has kept ad eundem single-pole double throw ceramic vacuum relay, the internal structure of redesign ceramic member has realized the quick purpose that the single-pole double throw relay is improved to the single-pole single-throw(SPST relay.
