Abstract
The utility model relates to a lapping structure of a circuit breaker static terminal shell. The lapping structure comprises two contact piece shells, wherein the contact piece shell comprises a shell body and a lapping layer, the lapping layer is located at the side wall of the shell body, and the edge of the lapping layer and the edge of the side wall of the shell body form a first step; the lapping layer is provided with lapping columns, and the lower end is provided with lapping blocks; the other side wall of the shell body is of an open structure, the inner edge of the shell body is provided with a second step matched with the first step, the shell body is internally provided with lapping holes matched with the lapping columns, and the lower end of the shell body is provided with a groove matched with the lapping blocks; the adjacent contact piece shells are connected together through matching the first step with the second step, matching the lapping columns with the lapping holes, and matching the lapping blocks with the groove. The lapping structure provided by the utility model adopts the technical scheme of matching the lapping columns with the lapping holes and matching the lapping blocks with the groove, thereby enabling the adjacent contact piece shells to not only keep tight connection, but also be convenient to assemble, disassemble and maintain.
Description
Technical field
The utility model relates to breaker connecting terminal, is specifically related to a kind of bridging arrangement of circuit breaker static terminal housing.
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, comprises moved end and static terminal, and the inserting groove of static terminal is chained together by screw rod, although in conjunction with tight, the repair and replacement use for a long time that is not easy to single inserting groove can affect quality and the useful life of binding post.Therefore, how to make to connect closely between the housing of breaker connecting terminal, and be convenient for changing again maintenance and become a technical barrier.
Summary of the invention
In order to solve above-mentioned technical problem, the utility model provides a kind of bridging arrangement of the circuit breaker static terminal housing that connects closely, is convenient for changing again.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of bridging arrangement of circuit breaker static terminal housing, comprise two contact housings, described contact housing comprises enclosure body and bonding layer, and described bonding layer is positioned on the sidewall of enclosure body, and the edge of the edge of bonding layer and the sidewall of enclosure body forms first step; Described bonding layer is provided with overlap joint Zhu， lower end and is also provided with overlap joint piece; Another sidewall of described enclosure body is open type structure, enclosure body inward flange is provided with the second step matching with first step, in enclosure body, be also provided with and the overlap joint hole that overlaps post and match, the lower end of enclosure body is also provided with and the groove that overlaps piece and match; Adjacent contact housing is by first step and second step, and overlap joint post and overlap joint hole, overlap cooperating together between piece and groove.
As preferably: described enclosure body upper end is provided with two raised lines, and lower end is provided with the 3rd 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.
The utility model, owing to adopting above-mentioned technical scheme, adopts step to coordinate, and overlap joint post coordinates with overlap joint hole, and overlap joint piece and groove fit, make adjacent contact housing can keep tight connection, is convenient to again dismounting and safeguards.Simple structure of the present utility model, connects reliably between parts, useful life is longer, compared with large reduction frequent replacing circuit breaker binding post and the cost that causes is higher and unhandy problem.
Accompanying drawing explanation
Fig. 1, Fig. 2 are structural representation of the present utility model.
Embodiment
