Abstract

A lamp arm fixing device of a junction box for a pendent lamp includes a lamp holder and a connection housing. When the connection housing is completely inserted in the lamp holder, the engaging plate of the lamp holder engages the positioning screw portion at one end of the connection housing whereby the connection housing is secured in the receiving hole of the lamp holder. The connection housing is defined with an open slot. A slide slot extends from an end of the open slot whereby when the connection housing is inserted in the lamp holder, the open slot is inserted in a direction facing the screw of the lamp holder and the screw extends through the open slot and is positioned in the slide slot. Thus, the female connector received in the connection housing is mated with the male connector received in the lamp holder in a proper direction.
