Abstract
The utility model relates to a wafer casing of a static terminal of a circuit breaker. The wafer casing includes a casing body and an overlapping layer. Two raised strips are arranged on the upper end of the casing body and the lower end of the casing body is provided with a first step. The side wall of the casing body is step-shaped and a wiring hole is arranged in the step-shaped side wall. Bayonets enabling a wafer to be right under the wiring hole are arranged in the casing body. Isolation plates are also arranged in the casing body. Wafer guide grooves are formed by the isolation plates and the inner wall of the casing body. And wafer openings are formed by the isolation plates and edges of the raised strips. The utility model provides the water casing in which a plug-in part is arranged in the wafer casing and wires are connected through the wiring hole so that wiring parts are protected effectively and contact performance is improved and service life is prolonged. Moreover, wiring and maintenance of the wafer casing are more convenient.
Description
Technical field
The utility model relates to breaker connecting terminal, is specifically related to a kind of contact housing of circuit breaker static terminal.
Background technology
Circuit breaker is used for connecting internal circuit and the external circuit in certain limit, and its effect is equivalent to master switch.The binding post of circuit breaker can be divided into wiring and plug-in connecting terminal after wiring before plate, plate according to connected mode, adopt the circuit breaker of plug-in connecting terminal, the interior necessary isolator of binding post that has omitted original general circuit breaker, has increased security reliability to operation and maintenance when having improved the economy of using.
Existing plug-in connecting terminal, comprise moved end and static terminal, static terminal is provided with inserting groove and wiring position, inserting groove is generally chained together by screw rod, when one of them breaks down, be difficult for changing, and plug-in connecting terminal is under the effect of driving mechanism, and static terminal and moved end are pegged graft repeatedly, long-term use can make the loose contact of wiring position, affects quality and the useful life of binding post.
Therefore, how to make the static terminal of circuit breaker more effective for the protection at wiring position, and maintenance and wiring is convenient becomes a technical barrier.
Summary of the invention
In order to solve above-mentioned technical problem, the utility model provide a kind of simple in structure, can effectively protect connecting portion, and be convenient to the contact housing of wiring.
To achieve the above object, the utility model has adopted following technical scheme:
A contact housing for static terminal, comprises enclosure body and bonding layer, and described enclosure body upper end is provided with two raised lines, and lower end is provided with first step, and a sidewall is step-like, and step-like sidewall is provided with wiring hole; In enclosure body, be provided with and make contact be positioned at the bayonet socket under wiring hole, be also provided with dividing plate in described enclosure body, the inwall of dividing plate and enclosure body forms contact gathering sill, and the edge of dividing plate and raised line formation contact mouth.
As preferably: the step-like side wall lower ends of described enclosure body is provided with bayonet socket, and another sidewall is provided with buckle, facilitates the installation of contact housing and static terminal.
As preferably: described bonding layer is provided with overlap joint Zhu， lower end and is also provided with overlap joint piece, makes the installation between adjacent contact housing more firm, strengthens the stability connecting.
As preferably: described bonding layer and enclosure body form second step, are convenient to the installation of adjacent contact housing.
The utility model, owing to adopting above-mentioned technical scheme, provides a kind of contact housing, and plugging position is arranged on to contact enclosure interior; by wiring hole wiring, effectively protected wiring position, and improved contact performance; extended useful life, and the convenient wiring of contact housing and maintenance.
