Combined type junction box

The invention discloses a kind of compound connection box. It includes a cover and the bottom which are connected by screw. On the four sides of the bottom, there sets an aperture and two connection slots on at least one side wall, there sets a concave slot along the lip of the aperture, the aperture has a plugging board, the shape of the plugging board is correspondent to the aperture and it is inserted into the concave slot to close the aperture, the connection slots are distributed at two sides of the aperture, there has a plug pin which is inserted from top down in the connection box, the plug pin is made up of two similar parallel and integral connection parts, one of them is in the connection slot, the second part extrudes out form the connection slot and matches with the another connection slot, the contacting side of the connection part and the connection slot are cross and localizes the plug pin along the thickness direction of the side wall, the plug pin and the board are sealed on the side wall. The structure in the invention is simple and reasonable, it is easy to be assembled, and the cost is low. 本发明公开了一种组合式接线盒。它包括用螺钉联接的面盖和底座，在底座的四个侧壁中，至少有一个侧壁上开设有一缺口和两联接槽，沿缺口的唇部开有凹槽，该缺口装有插板，插板的形状与缺口相应且从上向下插入凹槽从而封闭该缺口，联接槽布置于缺口两侧，联接槽内具有从上向下的插入的插销，插销由两个相同的、并排的、且连成一体的联接部构成，其中的一个联接部位于本组合式接线盒的联接槽内，第二个联接部从本组合式接线盒的联接槽内露出可供与另一相同结构的组合式接线盒的联接槽配合，联接部与联接槽的接触侧面呈交错状而使插销在侧壁厚度方向上定位，插销及插板都由面盖封装在侧壁上。本发明结构简单合理，组装方便，成本低。
