In prior art, the contact surface of the shell of breaker and the rear surface of breaker is plane, therefore when installing whole breaker module, along with the fastening of breaker module can cause breaker to be extruded distortion owing to contacting with each other between plane, cause the two gold dollar part of circuit breaker internal, spring position distortion, breaker operating characteristic is declined.And adopt this elasticity convex rib structure, in breaker skew along with circuit breaker position when fastening, the rear surface of breaker can extrude elasticity convex tendon makes elasticity convex tendon be out of shape, and breaker can not deform, avoid that breaker occurs slide fastener, can not close a floodgate, the appearance of the phenomenon such as asynchronous of closing a floodgate.
Wherein, described left and right fixed is also provided with screw holder.This setting is convenient to the base plate of screw from double-power supply switching device through fixing with breaker module.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of breaker module of double power supply converting switch.
The utility model have employed following technical scheme: a kind of breaker module of double power supply converting switch, and it comprises breaker and is coated on the shell outside breaker; Wherein, described enclosure is also provided with the terminal plate be made up of conductive material, is connected in the wiring hole of one end insertion breaker of terminal plate with binding post; The other end of terminal plate is used for being connected with wire.
Adopt the setting of terminal plate, wire can be connected on terminal plate and pass through terminal plate; In maintenance process, be convenient to maintenance; Find that terminal plate can insert in the wiring hole of breaker when not damaging by breaker to be again connected with binding post, compared with directly wire being adopted welding with binding post with prior art, improve the service life of breaker.
Wherein, described terminal plate comprises clamping part and wire connecting portion, there is angle between described clamping part and wire connecting portion; Clamping part inserts in the wiring hole of breaker, wire connecting portion offers wiring through hole.
Wherein, described angle is 90 °.
Adopt clamping part and wire connecting portion to be directly provided with angle, angle is 90 ° of limited spaces considering between breaker and shell, adopts this structure that terminal plate can be avoided to take large quantity space.
Wherein, described shell comprises upper cover, front shoe, rear fixed plate, left fixed mount, right fixed mount; Upper cover is positioned at the top of circuit breaker operating handle, and upper cover both sides are provided with barb; Described left and right fixed is positioned at the left and right sides of breaker, forward and backward fixed mount is provided with snap fit and draw-in groove, and the pre-installation hole I on snap fit and breaker is in connecting and fixing, and barb and draw-in groove are in connecting and fixing; Forward and backward fixed head lays respectively at the both sides, front and back of breaker; Described upper cover, left and right fixed are by coated to the top edge of forward and backward fixed head, left hand edge, right hand edge.
Adopt the shell mechanism of this form, be convenient to assemble between shell and breaker.
Wherein, described forward and backward fixed head is provided with boss, and boss is corresponding with the pre-installation through hole I that both sides before and after breaker are offered, when forward and backward fixed head coordinates with breaker, boss stretches in pre-installation through hole I, and the shape of described boss and pre-installation through hole I is concentric circles.
Wherein, described rear fixed plate is provided with elasticity convex tendon and the bar hole being convenient to pass through when elasticity convex tendon deforms, there is the rear surface of breaker when position offsets and act on elasticity convex tendon in breaker, elasticity convex tendon is out of shape.
