The utility model discloses a driving power supply shell, which comprises an upper cover, a base and a wiring terminal. A plurality of wiring terminals are divided into two groups and are arranged at both ends of the base. The upper cover is on the base, and the upper cover is provided with opening of the incoming and outgoing wires at both ends. The opening is respectively provided with tooth-shaped edges. A plastic part and a plastic part are arranged in the opening. The lower end edge is provided with a line-pressing tooth which can match the tooth-shaped edge. When the line-pressing tooth on the plastic part is pressed and sliding into the opening, the line-pressing tooth on the plastic part and the tooth-shaped edge on the opening cooperate to form a line-pressing structure which can bite the wire. A self-locking structure is also arranged between the side wall of the plastic part and the inner wall of the opening matched with the plastic part. It includes the first rack group and the second rack group which can bite each other. The utility model passes through a small plastic part with teeth, which is pressed directly, and the wire is pressed tightly, and the tighter the pressure, the less loose it is.
【技术实现步骤摘要】
一种驱动电源外壳
本技术涉及电路接线领域,尤其涉及一种驱动电源外壳。
技术介绍
现有技术中的带接线端子的电源外壳大多为一端进线,一端出线,两头螺丝压紧连接。这样的电源外壳电线容易松动,给使用造成不便。
技术实现思路
本技术目的是提供一种驱动电源外壳,此设备通过一个带有牙齿的小的塑料件,直接按下去,把电线压紧,越压越紧的,不会松动。为实现上述技术目的,本申请采用如下技术方案:一种驱动电源外壳,包括上盖和底座,所述上盖盖在底座上,上盖两端设有进、出导线的开口,其特征在于:开口分别设有齿形边缘,开口内活动套装有一塑料件,塑料件下端边缘设有能与上述齿形边缘配合的压线齿,在塑料件下压并滑套入开口内时,塑料件上的压线齿与开口上的齿形边缘上、下配合形成能咬紧导线的压线结构;所述塑料件侧壁与其配合的开口内壁之间还设有自锁结构,该自锁结构包括能相互咬合的第一齿条组和第二齿条组。第一齿条组上的多个齿条沿竖直方向分布在塑料件的侧壁上的凹槽内,第二齿条组上的多个齿条沿竖直方向分布在开口内壁上,第一齿条组上的齿条斜向上设置,第二齿条组上的齿条斜向下设置,在塑料件下压并滑套入开口内时,第一齿条组上的齿条能沿第二齿条组上的齿条边缘向下滑动,且第二齿条组上的齿条能向下钩住第一齿条组上的齿条以限制塑料件向上脱出开口。如上所述一种驱动电源外壳,其特征在于:所述开口上的齿形边缘有两个,两个齿形边缘水平方向并排设置,所述塑料件下端边缘对应设有能与上述两个齿形边缘配合的一对压线齿。如上所述一种驱动电源外壳,其特征在于:所述第一齿条组与所述塑料件整体注塑成型,第二齿条组与所述上盖整体注塑成型。本技术的有 ...
