Abstract
The utility model discloses a connecting piece for earth wires of electrical supply equipment and transformation equipment, which is characterized in that a lower connecting piece and an upper connecting piece are arranged on the connecting piece, wherein a convex cavity is arranged in the lower connecting piece, the upper connecting piece is of a reverted T shape, and a T-shaped transverse head of the upper connecting piece is inserted in the cavity of the lower connecting piece; the lower inner surface of the cavity is provided with an inclined angle a, and the upper surface is provided with an inclined angle b; the upper surface of the transverse head of the convex head is provided with an inclined angle c, and the lower surface is provided with an inclined angle d; and the angles of the inclined angles a, b, c and d range from 0 to 6 degrees. The transverse head of the T-shaped body of the upper connecting piece is fallen into the cavity of the lower connecting piece from a notch and then is rotated and tightly screwed; the electric wire inlet of the upper connecting piece is provided with the earth wire, and a bolt head and a nut which are arranged on the lower connecting piece are connected with earth electrode conductors. The connecting piece has the advantages of fast and convenient connection operation, easy disassembly, firm connection after installation and hard disengagement; application results show that the earth resistance can easily reach the mark and can be kept unchanged, and the connecting piece has simple structure, can be produced into series standard products and has favorable popularization and application value.
Description
Technical field
The utility model relates to a kind of for converting equipment earth connection connector.
Background technology
On for converting equipment and power consumption equipment, carry out ground connection, this is an important process, doing well can be accidents caused, causes casualties, and common way is with bolt, nut combinations between earth electrode and ground connection connecting line, make it to couple together, the method of the welding adopted is also arranged, make it to couple together, its shortcoming is, remove difficulty after the welding, when installing again, also to adopt the method for welding, inconvenience is arranged more; Adopt bolt, nut combinations, convenient disassembly, easy for installation again, yet, get loose easily, grounding resistance is difficult to remain unchanged, in addition chemistry and atmospheric corrosion, get rusty, earth resistance also can become greatly, influences the ground connection effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of new construction earthy quick connector.
A kind of speed is revolved the compression joint type earth terminal, it is characterized in that, is provided with down connector, is provided with the convex cavity in the following connector; Be provided with upper connector, upper connector becomes inverted T-shaped, and the cross-peen of its T body inserts in the cavity of following connector; Lower surface in the cavity has a inclination angle, and upper surface has the b inclination angle; The cross-peen upper surface of T body has the c inclination angle, and lower surface has the d inclination angle, 0～6 ° of a angular region, 0～6 ° of b angular region, 0～6 ° of c angular region, 0～6 ° of d angular region; Upper connector falls into down the connector cavity from gap, and rotation is tightened, and the wedging of upper connector cross-peen is the connector cavity down; Upper connector electric wire inlet is connected with earth connection, and bolt head, nut are connected with the earth electrode conductor on the following connector.
Adopt the utility model, attended operation fast, is conveniently dismantled easily, is connected firmly after the installation, is not easy to come off, and uses the result to show that earth resistance is up to standard easily, can remain unchanged again; The utility model is simple in structure, makes easily, can make the seriation standardized product, and applying of it can reduce project installation expense, maintenance cost, has good application prospects.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is made detailed description further.
As shown in Figure 1, upper connector 1 top is provided with electric wire access port 3, after earth conductor cable inserts, use jig, adopt extrusion, electric wire is fixed, make it and to come off, during the operation of recast ground connection, also needn't open, also can be as shown in Figure 3, earth connection inserts, and adopts bolt to be screwed into, it is compressed, fixing, during the operation of recast ground connection, also needn't open; Following connector 2 adopts bolt head 4 and nut to cooperate, and links to each other with the earth electrode conductor, removes bolt head 4, can will descend connector 2 usefulness welding manners to be connected with the earth electrode conductor; Upper connector 1, following connector 2 can adopt conductor metal materials such as copper, aluminium, carbon steel to make.
Using method: upper connector 1, by gap, insert in the cavity 7 of following connector, by spanner, rotation is tightened, in the cavity 7 with connector under cross-peen 6 wedgings of upper connector, 0～6 ° of a angular region, 0～6 ° of b angular region, 0～6 ° of c angular region, 0～6 ° of d angular region, for same set of load module, cannot a=b=c=d, cannot a=b, cannot c=d.Incline direction wants corresponding mutually, guarantees its large tracts of land contact, and enough frictional force is arranged.
