Abstract
The utility model discloses a replaceable relay contact terminal including a contact-terminal body, a basal body and a base. The basal body is arranged between the contact-terminal body and the base. The outer surface of the contact-terminal body is arc-shaped. The basal body includes an upper connection body and a lower cylindrical body. The diameter of the upper connection body is larger than that of the lower cylindrical body. Outer edges of the lower surface of the upper connection body are provided with circular projections. Clamping edges extend downwards from side edges of the contact-terminal body. Barbed edges bent inwards are formed at the clamping edges. The barbed edges are clamped at the inner sides of the annular projections. The base is of a cylindrical structure. The periphery of the upper surface of the base is flush with the lower surface of the lower cylindrical body. The replaceable relay contact terminal is reasonable in design and adopts the clamping structure and the contact-terminal body is replaceable so that cost is reduced. The replaceable relay contact terminal conforms to low carbon, high efficiency and sustainable development demands of industrial products in current society.
Description
Technical field
The utility model relates to relay technical field, is specifically related to a kind of removable relay contact.
Background technology
Relay is a kind of electric control device, is when the variation of input variable (energizing quantity) reaches regulation requirement, makes controlled volume that a kind of electrical equipment that predetermined step changes occurs in electric output circuit.It has control system (claim not only input circuit) and by the interactive relationship between control system (but also claiming output loop).Conventionally be applied in the control circuit of automation, it is actually a kind of " automatic switch " that goes to control large electric current running with little electric current.Therefore play the effects such as automatic adjusting, safeguard protection, change-over circuit in circuit.
Along with social development, the purposes of relay is more and more extensive, and kind is also more and more, and function and structure is also different.The contact of relay is the most important components of relay, and the contact that at present relay uses generally has two kinds of pure contact and composite contacts, uses its electric life of relay cost long but contact of pure contact expensive; Composite contact compares with pure contact that the cost of material is low, but uses the electric life of relay of composite contact also relatively low, and in order to guarantee the electric life of relay, in composite contact, composite bed or electrodeposited coating are often thicker.
Because contact and contact weld together, in use, if contact lost efficacy, will need to change relay, cause the wasting of resources.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide a kind of removable relay contact.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of removable relay contact, comprise contact body, matrix and base, described matrix is located between described contact body and base, the outer surface of described contact body is circular arc, described matrix comprises connector and lower cylinder, described upper connector diameter is greater than described lower cylinder, the lower surface outer rim of described upper connector is provided with annulus projection, described contact body side is extended with clamping limit straight down, the bending to the inside of described clamping limit has barbed edge, described barbed edge is connected in described annulus projection inner side, described base is cylindrical structure, the upper surface outer rim of described base is concordant with lower cylindrical lower surface.
