Abstract
The utility model provides an ideal circular tube-type bolt device wire clamp for the transformer station device accessory technology field. The circular tube-type bolt device wire clamp comprises a wiring circular tube, a wiring board, and pressing plates. The wiring circular tube is a hollow opening circular tube, and two sides of the opening are provided with two pressing plates. Because the wiring circular tube is the hollow opening circular tube, the two sides of the opening are provided with two pressing plates, the pressing plates are provided with connecting holes, and the pressing plates can be clamped tightly by using bolts, and therefore the contact area between the lead in the wiring circular tube and the wire clamp can be increased, and the contact surface can be increased by more than 50%, and the heating caused by the undersized contact surface can be prevented. Compared to the prior art, the circular tube-type bolt device wire clamp has advantages of simple structure, convenient operation, fast wiring speed, and high working efficiency.
Description
Technical field
The utility model relates to substation equipment attachment technique field, is specifically related to a kind of tubular type screw device wire clamp.
Background technology
The screw bolt-type device clamp is as important accessory of grid equipment, in network system, be extensive use of, because contact-making surface is few between screw bolt-type device clamp and the lead, half of not enough sectional area of wire, often heating between device clamp and the lead, cause equipment normally not move, accidents caused, influence power supply.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and contact-making surface increases by 50%, increases ampacity, can prevent the tubular type screw device wire clamp of contact-making surface heating.
For achieving the above object, the utility model adopts following technical scheme: this tubular type screw device wire clamp comprises terminal block, the wiring pipe, pressure strip, bolt, the plate face of terminal block is provided with connecting hole, terminal block links to each other with the wiring pipe, the middle part of wiring pipe is provided with opening, and the lower end of two row's pressure strips is contained in the opening part both sides respectively, and bolt is contained on pressure strip.
Described material is that aluminium matter or the copper terminal block of making are square plate, and the connecting hole that arranges on the plate face is the connecting hole of symmetry.
Described material is that aluminium matter or the copper wiring pipe of making are the hollow open pipe.
The utility model for substation equipment attachment technique field provides a kind of desirable its main feature of tubular type screw device line is; Comprise the wiring pipe, terminal block, pressure strip; The wiring pipe is the hollow open pipe, is provided with two row's pressure strips in the opening part both sides, and pressure strip is provided with several bolts, and the bolt end is provided with plain cushion, spring pad, nut successively; Because the wiring pipe is the hollow open pipe, be provided with two row's pressure strips in the opening part both sides, connecting hole on the pressure strip, by bolt pressure strip is tightened, thereby can increase the contact area of the lead in the wiring pipe and wire clamp, contact-making surface can increase to be increased more than 50%, can prevent therefore that contact-making surface is too small and generates heat.Compared with prior art, have simple in structurely, easy and simple to handle, wiring speed is fast, remarkable advantages such as operating efficiency height.
Description of drawings

Fig. 2 is vertical view of the present utility model.
Embodiment
Referring to Fig. 1 .2, shown a kind of tubular type screw device wire clamp comprises that material is aluminium matter or the copper terminal block of making 1, wiring pipe 3, pressure strip 4, bolt 5, terminal block 1 is square, the plate face of terminal block 1 is provided with the connecting hole 2 of symmetry, terminal block 1 links to each other with wiring pipe 3, the middle part of wiring pipe 3 is provided with opening, and the lower end of two row's pressure strips 4 is contained in the opening part both sides respectively, and bolt 5 is contained at pressure strip 4 and is used for wiring pipe 3 is clamped.
Because the face of contact wire is open-end tube, contact area increases by 50%, and opening can effectively prevent rain erosion down when wire clamp was installed.
