The utility model relates to electrical connector, and particularly weight-lifting equipment special wiring terminal row extensively is suitable for various model specification weight-lifting equipments and exchanges in all control setups of controlling as the following low voltage operating of 38V in 380V～220V, the 50HZ power circuit.

Background technology

Present weight-lifting equipment does not have special-purpose connecting terminal block, used common connecting terminal block is on a bakelite piece many pair of wire connection terminals to be installed side by side, be provided with the sliding fixing housing of joining in bakelite piece bottom, wire guide is arranged on housing, be provided with the wiring marking plate in the centre of each pair of wire connection terminals, on the wiring marking plate, indicate the wiring sign, be connected with the transparency cover that covers each connection terminal and marking plate on the top of bakelite piece corresponding to each pair of wire connection terminals place.The problem that this common connecting terminal block exists is, must import after the voltage transformer transformation with alternating current 380V voltage again and connect button, and the motor of weight-lifting equipment is operated control, in control box, be provided with voltage transformer, cause complexity is installed, increase cost, the waste electric energy.

Summary of the invention

The purpose of this utility model is a kind of compact conformation of design, and cost is low, the saving electric energy, safe and reliable weight-lifting equipment connecting terminal block.

The technical solution of the utility model is finished as follows, the weight-lifting equipment connecting terminal block, it includes drain pan and transparency cover, be arranged with two row's connection terminals on the bakelite piece top of joining with drain pan and transparency cover cunning, be equipped with a wiring marking plate by chute in the middle of on the bakelite piece the two row connection terminal, indicate the wiring sign corresponding to each connection terminal place on the wiring marking plate, it is characterized in that: in the cavity at bakelite piece middle part, be provided with a surface-mounted integrated circuit and a relay, two relay wiring terminals are arranged in the connection terminal, auxiliary open contact in one end of relay wiring terminal and the relay is connected, the other end with row on the button connection terminal link to each other, one end of power supply terminal connects the 380V alternating current, the other end is connected on the surface-mounted integrated circuit with buck functionality, be connected by the end of low tension with the motor cutoff connection terminal of arranging, one end of motor operation wiring terminal connects motor, and the interior AC contactor of the other end and electric cabinet is connected.Above-mentioned bakelite piece and connection terminal are to be formed by the butt joint of polylith bakelite fritter, have pair of terminals at least on each bakelite fritter, and the corresponding position is provided with jack and tenon mutually on each bakelite fritter.

The utility model is mounted on electronic integrated circuit plate and relay in the connecting terminal block, is installed in the electric control box of weight-lifting equipment, and its compact conformation, reliable operation has not only reduced productive costs, also can save electric energy, meets industry and national standard.
