Abstract
The invention discloses a kind of cluster type limber hook up probe, it contains columniform probe body, the front end of described probe body is provided with probe aperture, is fixed with probe beam in this probe aperture, and described probe beam is made up of at least two separate little probes, little probe described in each is formed by shank, spring and needle guard, wherein, described shank lower end and spring housing are contained in described needle guard, and, be provided with position-limit mechanism between described shank and needle guard, described needle guard is fixedly connected with described probe aperture.The present invention closely becomes a branch of insertion by multiple little probe and is fixed in 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 stud close contact, add excess current area, decrease the thermal value of probe body, improve measuring accuracy.
Description
technical field:
The present invention relates to the probe that a kind of ammeter line terminals uses, particularly relate to a kind of cluster type limber hook up probe.
background technology:
China is populous, and along with the fast development of economy, the living standard of people is greatly improved, and its living environment is also greatly improved, and then also more and more heavier to the demand of electric power.Watt-hour meter is the how many measurement instrument of electric power enterprise measuring power user power utilization, ensures the correct metering of watt-hour meter, is directly connected to the benefit of electric power enterprise, is also being responsible for user power utilization amount simultaneously.Current, watt-hour meter manufacturing enterprise needs when detecting watt-hour meter to use probe, but the probe used at present has the following disadvantages: the connection terminal of probe and watt-hour meter is Hard link, easily causes damage during grafting, affects the measuring accuracy of watt-hour meter.
summary of the invention:
Technical matters to be solved by this invention is: overcome the deficiencies in the prior art, provides that a kind of structure is simple, contact good, measurement is accurate and the cluster type limber hook up probe that thermal value is little.
Technical scheme of the present invention is:
A kind of cluster type limber hook up probe, containing columniform probe body, the front end of described probe body is provided with probe aperture, probe beam is fixed with in this probe aperture, described probe beam is made up of at least two separate little probes, described little probe close-packed arrays, described in each, little probe is by shank, spring and needle guard are formed, wherein, described shank lower end and spring housing are contained in described needle guard, and, position-limit mechanism is provided with between described shank and needle guard, the hole wall of described probe aperture is provided with note scolding tin hole, needle guard and the described probe aperture of described little probe are fixed by scolding tin, described probe body rear end has threaded hole and spanner screens.
Described shank bottom is provided with thin bar section, and the lower end of described thin bar section is provided with limited block, and described needle guard is provided with position limiting convex ring, and described limited block forms described position-limit mechanism together with position limiting convex ring.
Or described shank bottom is provided with thin bar section, and the lower end of described thin bar section is provided with limited block, described needle guard is provided with stop screw or pin, and described limited block forms described position-limit mechanism together 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.
The invention has the beneficial effects as follows:
1, the present invention closely becomes a branch of insertion by multiple little probe and is fixed in 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 stud close contact, add excess current area, decrease the thermal value of probe body, improve measuring accuracy.
2, the little probe of the present invention is made up of shank, spring and needle guard, and, be provided with position-limit mechanism between shank and needle guard, can prevent shank from departing from needle guard, use very convenient.
3, the present invention makes the needle guard of little probe and probe body fix by soldering, and its structure is simple, and easily make, cost is lower.
4, position-limit mechanism of the present invention adopts thin bar section, limited block and position limiting convex ring, and position limiting convex ring adopts later stage compacting to form, and structure is simple, easily makes.
5, probe body rear end of the present invention has threaded hole, can support the use with the probe base of many companies, in addition, probe body rear end end face has spanner screens, facilitates the installation of probe.
6, structure of the present invention is simple, 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.
accompanying drawing illustrates:
Fig. 1 is the structural representation of cluster type limber hook up probe;
Fig. 2 is the structural blast schematic diagram of the medium and small probe of Fig. 1;
Fig. 3 for probe little shown in Fig. 1 uncompressed time constitutional diagram;
Fig. 4 is the constitutional diagram shown in Fig. 1 during little probe compression.
embodiment:
Embodiment: see in Fig. 1-Fig. 4, figure, the little probe of 1-, 2-probe body, 3-notes 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, probe beam is fixed with in this probe aperture, probe beam is made up of (the present embodiment adopts 14 little probes) at least two separate little probes 1, and described in each, little probe 1 is formed by shank 5, spring 10 and needle guard 8, wherein, shank 5 lower end and spring 10 are sleeved in needle guard 8, further, be provided with position-limit mechanism between shank 5 and needle guard 8, needle guard 8 is fixedly connected with probe aperture.
Shank 5 bottom is provided with thin bar section 6, and the lower end of thin bar section 6 is provided with limited block 7, needle guard 8 is provided with position limiting convex ring 9, and position limiting convex ring 9 is that needle guard passes through radial compacting and forms, and limited block 7 forms position-limit mechanism together with position limiting convex ring 9.
Or adopt another kind of position-limit mechanism: arrange stop screw or pin carrys out alternative position limiting convex ring on needle guard 8, certainly, stop screw or pin can circumferentially arrange multiple, and limit effect is better.As required, shank 5 upper end can be provided with syringe needle syringe needle 4, the diameter of syringe needle 4 is greater than the diameter of shank 5, so also can limit the bulged-in extreme position of shank 5.
The hole wall of probe aperture is provided with note scolding tin hole 3, needle guard 8 and the probe aperture of little probe 1 are fixed by scolding tin, other modes can certainly be adopted to fix, be such as adhesively fixed etc., do not describe in detail one by one; Little probe 1 close-packed arrays; Probe body 2 rear end has 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 stud close contact, add excess current area, decrease the thermal value of probe body, improve measuring accuracy.
The above is only preferred embodiment of the present invention, and not do any pro forma restriction to the present invention, every any simple modification done according to technical spirit of the present invention, all still belongs in the scope of technical solution of the present invention.
