Abstract
The utility model discloses a novel ammeter terminal has metal terminal block, be equipped with the line hole on the metal terminal block, wherein: metal terminal block's upper portion perpendicular line hole direction is equipped with the lug, and the lug center is equipped with the screw hole that link up the line hole, and the housing screw is located threaded hole, and the bottom of screw hole is the unthreaded hole, and line block is pressed to downthehole being equipped with of line, the guide post of pressing line block to have curved crimping position and stretch into the unthreaded hole is equipped with the elasticity landing leg in the middle part of the pressure line block, the elasticity landing leg supports downtheholely on line. Make terminal and wire in close contact with compress tightly, the emergence of the terminal scaling loss avoiding causing because of contact failure, guarantee domestic appliance's normal use, contact endurance is long, has reduced the cost of maintaining.
Description
Technical field
This utility model relates to a kind of binding post, is specifically related to a kind of binding post being applicable on ammeter.
Background technology
Binding post is a kind of aftermarket product for realizing electrical connection, and along with industrial automatization is more and more higher and Industry Control requires increasingly stricter, accurate, the consumption of binding post gradually goes up.Along with the development of electron trade, the range of binding post gets more and more, and kind also gets more and more.At present, when wire is mounted connected in the rosette of ammeter, typically directly wire is plugged on the wiring hole of rosette, and by the line pressing bolt that falls, the wire being placed in wiring hole is fixed.So carry out wiring or take out stitches operation time, there is electric wire scaling loss or binding post when electric wire compresses loosely and get rusty the situation of oxidation in this structure, screw gets rusty easily and cannot split out, and can only change ammeter, and maintenance cost is high.And owing to wire core majority is made up of many copper cash, when especially multiple conducting wires is connected on a stud, core is easy to line pressing bolt extrusion or does not has compacted, thus causes wire physical cabling area to reduce, and wiring is the most inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, it is provided that a kind of simple in construction, compact conformation, wiring are firmly applicable to the binding post on ammeter.
For achieving the above object, the technical solution adopted in the utility model: this ammeter binding post, there is metal connection block, described metal connection block is provided with string holes, it is characterized in that: the upper vertical string holes direction of described metal connection block is provided with projection, projection center is provided with the screwed hole of through string holes, housing screw is positioned at screwed hole, the bottom of screwed hole is unthreaded hole, wire pressing block it is provided with in string holes, described wire pressing block has the crimping position of arc and stretches into the lead of unthreaded hole, is provided with resilient legs in the middle part of wire pressing block, and described resilient legs is supported in string holes.
Described resilient legs is curved.
Use the beneficial effect of technique scheme: this ammeter binding post has wire pressing block, wire pressing block is for crimping the wire of string holes to be inserted, move down under the spinning of housing screw, wire pressing block does not rotates, only move up and down, the wire that many copper cash are constituted all can be compressed, it is to avoid the defect that in prior art, conductor contact surface is little.Wire pressing block contact wire position is arcwall face, can well conductive contact, good connecting effect.Being provided with resilient legs in the middle part of described wire pressing block, described resilient legs is supported in string holes, makes string holes unobstructed, and described resilient legs is curved, it is to avoid wire stops the problem of wire when inserting string holes, and grafting is convenient.After and being pushed down wire by wire pressing block in wire inserts string holes, continue to screw housing screw, make wire pressing block be in close contact with wire and compress, avoid the generation of the binding post scaling loss caused because of loose contact, ensureing the normal use of household electrical appliance, contact endurance is long, reduces the cost of maintenance.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings specific embodiment of the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Ammeter binding post as shown in Figure 1, there is metal connection block 1, described metal connection block is provided with string holes 3, wire 2 to be connected can be inserted in string holes 3, the upper vertical string holes direction of described metal connection block is provided with projection 8, projection 8 is structure as a whole with metal connection block 1, projection center is provided with the screwed hole 9 of through string holes, housing screw 7 screws in screwed hole 9, the bottom of screwed hole 9 is unthreaded hole 10, wire pressing block 5 it is provided with in string holes, described wire pressing block has the crimping position of arc and stretches into the lead 6 of unthreaded hole, lead 6 is for being vertically directed effect, wire pressing block 5 can move up and down under the guide effect of lead 6.Wire pressing block bottom is provided with resilient legs 4, and described resilient legs 4 is supported in string holes 3, makes string holes unobstructed.
