Description
技术领域technical field
本实用新型具体涉及一种塑壳漏电断路器。The utility model specifically relates to a molded case leakage circuit breaker.
背景技术Background technique
塑壳漏电断路器是低压配电系统中重要的保护装置，在低压配电系统中它起到接通、分断正常工作电流，同时具有对交流电网线路及用电设备提供短路保护、过载保护、欠电压保护等。现有的塑壳漏电断路器由于其内部的接线板结构设计不够合理，该结构设计的接线板存在铜材用量较大，从而提高了该塑壳漏电断路器的生产成本。Molded case leakage circuit breaker is an important protection device in the low-voltage power distribution system. In the low-voltage power distribution system, it can connect and break the normal working current. At the same time, it can provide short-circuit protection, overload protection, Undervoltage protection, etc. Due to the unreasonable structural design of the wiring board inside the existing molded case leakage circuit breaker, the wiring board of this structure design has a large amount of copper material, thereby increasing the production cost of the molded case leakage circuit breaker.
发明内容Contents of the invention
本实用新型的目的在于克服现有技术的缺陷，提供一种结构简单、生产成本低的塑壳漏电断路器。The purpose of the utility model is to overcome the defects of the prior art and provide a molded case leakage circuit breaker with simple structure and low production cost.
为实现上述目的，本实用新型采用一种塑壳漏电断路器，包括基座、上盖、操作机构、灭弧系统、热脱扣系统、与操作机构联动设置的动触头、进接线板，所述的进接线板呈Z型，所述的基座上对应进接线板处设置有安装凸台，所述的进接线板通过螺钉固定在所述的安装凸台上，且进接线板的一端上对应动触头处设置有静触头，该进接线板的另一端连接在基座上的接线端子上。In order to achieve the above purpose, the utility model adopts a molded case leakage circuit breaker, which includes a base, an upper cover, an operating mechanism, an arc extinguishing system, a thermal tripping system, a moving contact set in linkage with the operating mechanism, and an incoming terminal block. The entry wiring board is Z-shaped, the base is provided with a mounting boss corresponding to the entry wiring board, the entry wiring board is fixed on the installation boss by screws, and the entry wiring board One end is provided with a static contact corresponding to the moving contact, and the other end of the incoming wiring board is connected to the wiring terminal on the base.
本实用新型的有益效果是：该塑壳漏电断路器的进接线板是通过将铜板材一次冲压折弯成型的Z型结构，该结构简单、加工便捷，且将原有的塑壳漏电断路器的基座加以改良，在基座上设置有用于安装进接线板的安装凸台，通过在基座上设置有与进接线板相配合的安装凸台，从而缩短了静触点与接线端子之间的垂直距离，进而缩短了该Z型进接线板的折弯高度，减少了该进接线板的铜材用量，从而节省了该塑壳漏电断路器的生产成本。The beneficial effect of the utility model is that: the incoming wiring board of the molded case leakage circuit breaker is a Z-shaped structure formed by stamping and bending the copper plate once. The base is improved, and the base is provided with a mounting boss for installing into the wiring board. By setting the mounting boss on the base to match the incoming wiring board, the distance between the static contact and the wiring terminal is shortened. The vertical distance between them shortens the bending height of the Z-shaped incoming terminal board, reduces the copper consumption of the incoming terminal board, and saves the production cost of the molded case leakage circuit breaker.
