Abstract
A connecting terminal for guaranteeing reliable connection of heating wire comprises a plate-shaped metal body and a fixed hole arranged on the upper part of the metal body, and is characterized in that a gap is formed on the upper part of the metal body, the gap is perpendicular to the axial line of the fixed hole, an arc-shaped concave groove for penetrating through the heating wire is arranged in the gap and the arc-shaped concave groove penetrates through both ends of the gap. The utility model has the beneficial effects that the heating wire penetrates through the arc-shaped concave groove of the connecting terminal and is clamped tightly by bolts so that the line contact of the heating wire and the connecting terminal is changed to annular surface contact, the width of the arc-shaped concave groove is adjusted through adjusting the tightness degree of bolts based on the elastic deformation of metal material; thereby, the heating wire is ensured to be connected with the conducting wire reliably; the loose connection and sparking situations are avoided.
Description
Technical field
The utility model relates to a kind of binding post of heater strip, is a kind of reliable binding post that connects of heater strip that guarantees specifically, and the heating wire that is mainly used in the heating wire heater connects.
Background technology
Because stove is harder with heater strip, when general heater strip lead-in wire is connected with lead, by bolt, nut and pad the heater strip lead-in wire is pushed down, heater strip only is that line contacts with binding post, resistance is very high, and local temperature raises when causing heating, and crimping is loosening after use a period of time, the then bigger appearance sparking of resistance causes the stove silk to blow.
Summary of the invention
Blow phenomenon in order to overcome resistance that line contact the causes stove silk that causes that raises, the utility model provides a kind of binding post, can guarantee that by this plate the stove silk reliably is connected with lead.
The technical scheme that the utility model adopted is: comprise tabular metal body, be provided with fixing hole in this upper part of body, it is characterized in that, be provided with the slit in described upper part of body, this slit is vertical with the axial line of described fixing hole, be provided with the arc groove that is used to pass heater strip in this slit, this arc groove is through the two ends in slit.
Described arc groove is located between described fixing hole and the bottom, slit.
Two ends at described arc groove are provided with extension mouth.
The beneficial effects of the utility model are: heater strip penetrates the arc groove of binding post, and heater strip is clamped with bolt, heater strip contacts with the line of binding post and becomes the anchor ring contact, utilize the strain of metal material itself, adjust the width of arc groove by the degree of tightness of bolt, thereby guaranteed that the stove silk reliably is connected with lead, avoided connecting loosening and sparking.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is an application example schematic diagram of the present utility model.
Among the figure: 1, porcelain spare or bakelite, 2, binding post, 21, the slit, 22, fixing hole, 23, arc groove, 24, extension mouth, 3, bolt, 4, the line nose, 5, heater strip, 6, nut.
Embodiment
Referring to Fig. 1～Fig. 3, the utility model comprises tabular metal body 2, be provided with fixing hole 22 in this upper part of body, be provided with slit 21 on the top of described body 2, this slit 21 is vertical with the axial line of described fixing hole 22, be provided with the arc groove 23 that is used to pass heater strip 5 in this slit 21, this arc groove 23 is 21 two ends (two ends, the left and right sides shown in Figure 1) through the slit.
Described arc groove 23 is located between the bottom in described fixing hole 22 and slit 21.Be provided with extension mouth 24 (chamfering or fillet) at the two ends of described arc groove 23, with the insertion that makes things convenient for heater strip with prevent from the bending of heater strip is damaged.
In the embodiments of figure 3, binding post 2 makes and is fixed by bolts on porcelain spare or the bakelite 1, can not change to guarantee two binding post 2 positions, and heater strip 5 penetrates in the arc groove 23 of binding post, then use bolt 3 to pass fixing hole 22, and use nut 6 that line nose 4 is pressed on the binding post 2, like this, when screwing bolt 3 and nut 6, slit 21 width of binding post 2 can diminish, thereby heater strip 5 is tightly embraced, and simultaneously, line nose 4 is pressed on the binding post 2 by nut 6.Like this, line nose 4 all contacts with 2 of binding posts with heater strip 5, and reliable clamping force effect (lever principle) is arranged all the time, thereby has guaranteed good electric conductivity, has eliminated the possibility of loosening sparking.
Claims (3)
1, a kind of reliable binding post that connects of heater strip that guarantees, comprise tabular metal body, be provided with fixing hole in this upper part of body, it is characterized in that, be provided with the slit in described upper part of body, this slit is vertical with the axial line of described fixing hole, is provided with the arc groove that is used to pass heater strip in this slit, and this arc groove is through the two ends in slit.
2, the reliable binding post that connects of assurance heater strip according to claim 1 is characterized in that described arc groove is located between described fixing hole and the bottom, slit.
