摘要：【中文】本发明涉及照明技术领域，尤其涉及一种连接装置，包括连接主体和固定螺丝，连接主体呈工字型，其上具有两个开口相背的凹槽，连接主体上对应每个凹槽均设置有两个间隔的螺纹固定孔，两个凹槽内的螺纹固定孔通过导电片一一对应电导通，同一个凹槽内的两个螺纹固定孔未电导通，固定螺丝旋拧在螺纹固定孔内，其的端部延伸至凹槽内与灯条上的焊盘和/或电源的导线抵接并电导通。通过将连接主体设置为工字型，使得连接主体上的凹槽可供任何宽度的灯条拼接，同时也能实现电源的导线与灯条拼接或者导线与导线的拼接，整个连接装置应用的范围更广，通用性更强，另外，连接装置的结构简单，可以有效降低拼接难度，提升拼接效率。 【EN】The invention relates to the technical field of lighting, in particular to a connecting device which comprises a connecting main body and a fixing screw, wherein the connecting main body is I-shaped, two grooves with opposite openings are formed in the connecting main body, two spaced thread fixing holes are formed in the connecting main body and correspond to each groove, the thread fixing holes in the two grooves are electrically communicated in a one-to-one correspondence mode through conducting strips, the two thread fixing holes in the same groove are not electrically communicated, the fixing screw is screwed in the thread fixing holes, and the end portion of the fixing screw extends into the groove and is abutted against and electrically communicated with a bonding pad on a lamp strip and/or a lead of a power supply. Through setting up connecting body into the I shape for the recess in the connecting body can supply the lamp strip concatenation of any width, also can realize the wire of power and the concatenation of lamp strip concatenation or wire and wire simultaneously, and the scope that whole connecting device used is wider, and the commonality is stronger, and in addition, connecting device's simple structure can effectively reduce the concatenation degree of difficulty, promotes concatenation efficiency.
