Description
Technical field
The utility model relates to a kind of relay, concrete ground a kind of terminal formula relay that integrates terminal and relay function of saying so.
Background technology
The principle of relay is made up of secured core, moving iron core, spring, moving contact, fixed contact, coil, binding post and shell.Coil electricity, moving iron core moves adhesive under the electromagnetic force effect, drive the moving contact action, normally-closed contact are separated, the normally opened contact closure; Coil blackout, moving iron core drives moving contact and resets under the effect of spring.The purposes of relay is to be used for transmitting signal or to control a plurality of circuit simultaneously; Also can directly control low capacity motor or other electric executive components with it; Relay is the effect of between control system and field apparatus, playing interface, and concrete function has: switch DC and AC load (resistive load, inductive load, capacitive load and mixed type load are arranged), carry out level match, with small-signal amplification, electrical isolation, number of signals expansion etc.
All the time, the volume of relay product excessive with wiring be not two problems that always perplex the Mechanic Engineer.Because cabinet space is limited; Especially littler for the cabinet space of movable equipment; And present relay is because its bigger volume; Often the total interface device of a cover control system need take up with a plurality of control racks, needs wiring between a large amount of use cabinets, has brought many troubles for installation, use and follow-up maintenance etc.
Summary of the invention
The purpose of the utility model is the defective to prior art, but provide a kind of volume little, can plug and the terminal formula relay of bridge joint.
The purpose of the utility model solves through following technical scheme:
A kind of terminal formula relay comprises the relay body, and said relay upper part of body is provided with the slot that opening makes progress, and is provided with the relay head in the slot, and the relay head is corresponding continuous with the jack that the slot bottom is provided with through the plug that its underpart is provided with; The sidewall of relay body is provided with wiring hole and the bridge joint position that is provided with at interval, and the bottom of relay body is provided with and its chimeric mounting guide rail that links to each other.
Extend to the middle part of relay body the inner end of said bridge joint position.
Described bridge joint position is symmetricly set on the relay body.
Described bridge joint position is the jump ring structure.
The top, upper end of the relay body of described slot both sides is respectively equipped with indicator light and plug snap close.
The thickness of said relay body is not more than 14mm.
The utility model is compared prior art has following advantage:
The terminal formula relay thickness of the utility model can be as small as 6.2mm; Overall volume is little; Can the total interface device of a cover control system all be installed in the control rack, satisfy control system to saving the requirement in space, for the miniaturization of control system provides maybe.
Adopt plug to link to each other between relay body of the utility model and the relay head, have pluggable characteristic, and the plug of relay head lower end has two kinds of mechanical type and solid states with jack, applied widely.
The utility model adopts the mode of current potential bridge joint, and the bridge joint position of jump ring structure is set on the relay body, but is employed in the equipotential bridge joint that uses the mode Rapid Realization relay of bridging piece in the bridge joint position; The use of bridge joint position and bridging piece has not only improved wiring efficient simultaneously, and owing to reduced the use of lead, the lead that relay is connect is a holding wire basically, has improved the efficient of later maintenance and has reduced error rate.
