Abstract
The utility model discloses a sleeve type combination probe which contains a cylindrical probe body, wherein the back end of the probe body is provided with an outwards-convex ring; the front end of the probe body is sleeved with a sleeve; the convex ring and the sleeve form a clearance fit; the probe body between the lower end surface of the sleeve and the upper end surface of the convex ring is sleeved with a compression spring; the wall of the sleeve is provided with a strip-shaped sliding chute; a spacing pin is arranged in the strip-shaped sliding chute; the inner end of the spacing pin is connected with the probe body; the front end surface of the probe body is a cambered surface; and the cambered surface is provided with a thread. By arranging the compression spring on the probe body, the utility model ensures the close contact between the sleeve and the outer wall of a wiring hole, thereby increasing the current flow area and reducing the heating value of the probe. Besides, the front end of the probe body is provided with a threaded cambered surface, thereby ensuring the better compression joint with a wiring terminal of an electric energy meter.
Description
One. technical field: the utility model relates to a kind of ammeter connection terminal probe, particularly relates to a kind of telescopic combination probe.
Two. background technology: China is populous, and along with rapid economy development, people's living standard is greatly improved, and its living environment is also greatly improved, and then also more and more heavier to the demand of electric power.Electric energy meter is what a measurement instrument of electric power enterprise metering power consumer electricity consumption, guarantees the correct metering of electric energy meter, is directly connected to the benefit of electric power enterprise, also is simultaneously being responsible for the user power utilization amount.Current, electric energy meter manufacturing enterprise need use probe when detecting electric energy meter, and still, not enough below the probe that uses at present exists: the connection terminal of probe and electric energy meter is hard the connection, causes damage during grafting easily, influences the measuring accuracy of electric energy meter.
Three. the utility model content:
The utility model technical matters to be solved is: overcome the deficiency of prior art, a kind of simple in structure, contact good and thermal value is little telescopic combination probe is provided.
The technical scheme of the utility model is: a kind of telescopic combination probe, contain columniform probe body, and said probe body rear end is provided with outside bulge loop; Sleeve of said probe body front end suit, the two clearance fit is set with compression spring on the probe body between said sleeve lower surface and the said bulge loop upper surface; The barrel of said sleeve is provided with the bar shaped chute; Be provided with a spacer pin in the said bar shaped chute, said spacer pin is inner to be connected with said probe body, and said probe body front end face is a cambered surface; And said cambered surface is provided with screw thread.
Said bar shaped chute is more than one, is uniformly distributed along the circumference.The outer round surface of said bulge loop is provided with the spanner screens; Said probe body rearward end axle center is provided with connection screw thread hole.
Said spacer pin the inner links together through the pin-and-hole that is provided with on wringing fit and the said probe body.Perhaps, said spacer pin the inner links together through the threaded hole that is provided with on screw thread and the said probe body.
The beneficial effect of the utility model is:
1, the utility model probe body is provided with compression spring, and sleeve is closely contacted with the wiring hole outer wall, has increased the excess current area, has reduced the thermal value of probe.
2, the utility model probe body front end face is the screw thread cambered surface, can be better and the binding post of electric energy meter carry out crimping, contact is good.
3, the utility model makes sleeve directed moving on probe body through spacer pin and bar shaped chute, and it is simple in structure, makes easily, and cost is lower.
4, the utility model probe body rear end has connection screw thread hole, can with the supporting use of the probe base of many companies, in addition, have the spanner screens on the bulge loop outer round surface of probe body rear end, make things convenient for the installation of probe body.
5, the utility model is simple in structure, contact good and thermal value is little, and its sales volume is big, is easy to promotion and implementation, has good economic benefit.
Four. description of drawings:
Fig. 1 is the structural representation of telescopic combination probe;
Fig. 2 is the vertical view of telescopic combination probe shown in Figure 1.
Five. embodiment:
Embodiment: referring to Fig. 1-Fig. 2, among the figure, 1-probe body, 2-connection screw thread hole, 3-compression spring, 4-sleeve, 5-bar shaped chute, 6-spacer pin, 7-screw thread, the screens of 8-spanner.
Telescopic combination probe contains columniform probe body 1, and wherein, probe body 1 rear end is provided with outside bulge loop; Sleeve 4 of probe body 1 front end suit, the two clearance fit is set with compression spring 3 on the probe body 1 between sleeve 4 lower surfaces and the bulge loop upper surface; The barrel of sleeve 4 is provided with bar shaped chute 5, is provided with a spacer pin 6 in the bar shaped chute 5, and spacer pin 6 the inners are connected with probe body 1; Probe body 1 front end face is a cambered surface, and cambered surface is provided with screw thread 7.
Bar shaped chute 5 is (to be one, also can be two, three or four) more than one among the figure, when a plurality of, is uniformly distributed along the circumference.The outer round surface of bulge loop is provided with spanner screens 8, and probe body 1 rearward end axle center is provided with connection screw thread hole 2.
Spacer pin 6 the inners link together through the pin-and-hole that is provided with on wringing fit and the probe body 1, and perhaps, spacer pin 6 the inners link together through the threaded hole that is provided with on screw thread and the probe body 1.
During use, probe body 1 is connected with probe base through connection screw thread hole 2, and compression spring 3 can make sleeve 4 closely contact with the wiring hole outer wall, has increased the excess current area, has reduced the thermal value of probe.Probe body 1 front end face is the screw thread cambered surface, can be better and the binding post of electric energy meter carry out crimping, contact is good.
The above only is the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction, and every any simple modification of doing according to the technical spirit of the utility model all still belongs in the scope of the utility model technical scheme.
