Description
Technical field
It the utility model is related to a kind of detachable electrical current transformer.
Background technology
Straight-through current transformer is a kind of common electronic parts, easy for installation because its wiring is simple, is widely used in counting
In amount, detection and protection circuit.
The front and rear housings of straight-through current transformer is fixed, and is fixed with junction block at the top of straight-through current transformer,
But component wear inside current transformer or when needing repairing, just need to turn on each screw, then by wiring
Seat and front and rear housings, which are pulled down, could complete detachable maintaining, be inconvenient.
Utility model content
The purpose of this utility model is to be to overcome above-mentioned deficiency, there is provided one kind can be with fast assembling-disassembling, and that conveniently repairs can
Tear formula current transformer open.
What the purpose of this utility model was realized in：
A kind of detachable electrical current transformer, it includes procapsid and back casing, and the centre of procapsid and back casing offers
Central through hole, and the rear side of procapsid is provided with multiple snap fits, and the front side of the back casing is provided with multiple necks, snap fit and neck
Procapsid, back casing are fitted together after cooperation, the centre of the procapsid and back casing is placed with two binding posts, institute
The top for stating procapsid and back casing is provided with junction block, and the wiring seating face is provided with through hole, is used for threading and terminals in through hole
Son is connected, and junction block is symmetrically provided with groove in the horizontal direction at bottom, and two grooves are oppositely arranged, and procapsid
Raised line is provided with the horizontal direction with the top of back casing, and two raised lines are stuck in the groove of junction block, so as to by procapsid, rear shell
Body, junction block Fast Installation or dismounting.
The utility model has an advantageous effect in that：
Coordinated between the procapsid and back casing of this detachable electrical current transformer by snap fit and neck, can be quickly complete
Into installation and removal, junction block is symmetrically provided with groove in the horizontal direction at bottom in addition, and procapsid and back casing
Top is provided with raised line in the horizontal direction, and two raised lines are stuck in the groove of junction block, so as to by procapsid, back casing, junction block
Fast Installation or dismounting, and then it is easy to maintenance and member replacing.
