Abstract
The utility model discloses a cluster flexible combined probe. The probe comprises a cylindrical probe body, wherein a probe hole is arranged at the front end of the probe body, a probe cluster is fixed in the probe hole, the probe cluster consists of at least two small probes, small probes are independent, each of small probes consists of a probe rod, a spring and a probe sleeve, lower ends of probe rods and springs are sleeved in probe sleeves, limiting mechanisms are arranged between probe rods and probe sleeves, and probe sleeves are fixedly connected to the probe hole. A plurality of small probes are clustered to be inserted and fixed in the probe body, after the probe body is inserted in an ammeter, all small probes are telescopic and are small in volume, small probes can be inserted in small gaps, small probes are in tight contact with small walls of wiring holes and studs, the overcurrent area is increased, the heating amount of the probe body is reduced and the measurement accuracy is improved.
Description
Technical field:
The utility model relates to the probe that a kind of ammeter line terminals is used, and particularly relates to a kind of cluster type limber hook up probe.
Background technology:
China is populous, and along with the fast development of economy, people's living standard is greatly improved, and its living environment also is greatly improved, and then also more and more heavier to the demand of electric power.Watt-hour meter is what measurement instrument of electric power enterprise measuring power user power utilization, guarantees the correct metering of watt-hour meter, is directly connected to the benefit of electric power enterprise, also is simultaneously being responsible for the user power utilization amount.Current, watt-hour meter manufacturing enterprise need to use probe when detecting watt-hour meter, and still, the probe that uses at present has the following disadvantages: probe is connected connection terminal with watt-hour meter be hard connection, and easy injury during grafting affects the measuring accuracy of watt-hour meter.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of simple in structure, contact good, measurement is accurate and thermal value is little cluster type limber hook up probe is provided.
The technical solution of the utility model is: a kind of cluster type limber hook up probe, contain columniform probe body, the front end of described probe body is provided with probe aperture, be fixed with probe beam in this probe aperture, described probe beam is comprised of at least two separate little probes, each described little probe consists of by shank, spring and needle guard, wherein, described shank lower end and spring housing are contained in the described needle guard, and, be provided with position-limit mechanism between described shank and the needle guard, described needle guard is fixedly connected with described probe aperture.
Described shank bottom is provided with thin bar section, and the lower end of described thin bar section is provided with limited block, is provided with position limiting convex ring on the described needle guard, and described limited block consists of described position-limit mechanism with position limiting convex ring.
Perhaps, described shank bottom is provided with thin bar section, and the lower end of described thin bar section is provided with limited block, is provided with stop screw or pin on the described needle guard, and described limited block consists of described position-limit mechanism with stop screw or pin.
Described shank upper end is provided with syringe needle, and the diameter of described syringe needle is greater than the diameter of described shank.Be provided with on the shank and annotate the scolding tin hole, the needle guard of described little probe and described probe aperture are fixed by scolding tin; Described little probe close-packed arrays; Described probe body rear end has threaded hole and spanner screens.
The beneficial effects of the utility model are:
1, the utility model closely becomes a branch of insertion by a plurality of little probes and is fixed in the probe body, after probe body inserts ammeter, because each little probe all can stretch separately, and little probe volume is little can insert micro gap, make little probe and wiring hole outer wall and double-screw bolt close contact, increase the excess current area, reduced the thermal value of probe body, improved measuring accuracy.
2, the little probe of the utility model is made of shank, spring and needle guard, and, be provided with position-limit mechanism between shank and the needle guard, can prevent that shank breaks away from needle guard, uses very convenient.
3, the utility model fixes the needle guard of little probe and probe body by soldering, and it is simple in structure, makes easily, and cost is lower.
4, the utility model position-limit mechanism adopts thin bar section, limited block and position limiting convex ring, and position limiting convex ring adopts the later stage compacting to form, and is simple in structure, makes easily.
5, the utility model probe body rear end has threaded hole, can support the use with the probe base of many companies, in addition, has the spanner screens on the end face of probe body rear end, makes things convenient for the installation of probe.
6, the utility model is simple in structure, contact good, measurement is accurate and thermal value is little, and its sales volume is large, is easy to promotion and implementation, has good economic benefit.
Description of drawings:
Fig. 1 is the structural representation of cluster type limber hook up probe;
Fig. 2 is the structure exploded perspective view of the medium and small probe of Fig. 1;
Fig. 3 is the constitutional diagram of little probe shown in Figure 1 when not compressing;
Constitutional diagram when Fig. 4 is little probe compression shown in Figure 1.
Embodiment:
Embodiment: referring to Fig. 1-Fig. 4, among the figure, the little probe of 1-, the 2-probe body, 3-annotates scolding tin hole, 4-syringe needle, 5-shank, 6-thin bar section, 7-limited block, 8-needle guard, 9-position limiting convex ring, 10-spring.
Cluster type limber hook up probe contains columniform probe body 2, wherein: the front end of probe body 2 is provided with probe aperture, be fixed with probe beam in this probe aperture, probe beam forms (present embodiment adopts 14 little probes) by at least two separate little probes 1, and each described little probe 1 consists of by shank 5, spring 10 and needle guard 8, wherein, shank 5 lower ends and spring 10 are sleeved in the needle guard 8, and, being provided with position-limit mechanism between shank 5 and the needle guard 8, needle guard 8 is fixedly connected with probe aperture.
Perhaps adopt another kind of position-limit mechanism: stop screw is set or pin substitutes position limiting convex ring at needle guard 8, certainly, stop screw or pin can arrange along circumference a plurality of, and limit effect is better.As required, can be provided with syringe needle syringe needle 4 in shank 5 upper ends, the diameter of syringe needle 4 so also can limit shank 5 bulged-in extreme positions greater than the diameter of shank 5.
Be provided with on the shank 5 and annotate scolding tin hole 3, needle guard 8 and the probe aperture of little probe 1 are fixed by scolding tin, can certainly adopt other modes to fix, and such as being adhesively fixed etc., do not describe in detail one by one; Little probe 1 close-packed arrays; Probe body 2 rear ends have threaded hole and spanner screens (not shown in FIG.).
During use, probe body 2 is connected with probe base by threaded hole, after probe body 2 inserts ammeter, because each little probe 1 all can stretch separately, and little probe 1 volume is little can insert micro gap, makes little probe 1 and wiring hole outer wall and double-screw bolt close contact, has increased the excess current area, reduce the thermal value of probe body, improved measuring accuracy.
The above only is preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction, and any simple modification that every foundation technical spirit of the present utility model is done all still belongs in the scope of technical solutions of the utility model.
