Abstract
The utility model relates to a screw-thread fixed claw protector which is composed of a porcelain plate (3) and copper connecting wire clamping plates (1) and (4) which are fixed on the both ends by bolts (2). The difference is that the internal diameter of the connecting wire clamping plate (4) is provided with threads which are matched with a conductive rod, and one single side is provided with an inner diameter regulating opening. In addition, one layer hot dipped stannum transition layer is arranged at the section which is contacted with an aluminium conducting wire or a safety sheet. Thus the problems of small and untight connection plane and galvanic corrosion among copper and aluminium pieces can be avoided.
Description
The utility model relates to a kind of controller switching equipment lead-in wire special-purpose member, promptly a kind of novel goat's horn protector.
At present on the goat's horn protector uses, goat's horn protector wiring clamping plate one end directly is clipped on the equipment conducting rod, owing on the equipment conducting rod screw thread is arranged, certainly will form goat's horn protector clamping plate like this contacts with equipment conducting rod formation dotted line, current-carrying area deficiency, thereby make and increase the resistance intensification between goat's horn protector and the conducting rod contact-making surface, heat is transmitted on the equipment sealing film by conducting rod, make film aging, break, cause the equipment oil leakage infiltration, even burn out conducting rod or porcelain spare is burst, cause operation troubles.In addition, existing goat's horn protector two ends clamp is a copper spare, and connected safety plate and lead are aluminum products, so copper aluminium couple corrosion phenomenon often takes place, influences normal power supply.
The purpose of this utility model provides and a kind ofly contacts closely with the equipment conducting rod, conducts electricity very well, and with safety plate, aluminum conductor the goat's horn protector of copper aluminium conductor couple corrosion phenomenon can not take place.
Above-mentioned purpose is realized by following scheme: this goat's horn protector is constituted by porcelain plate (3) with the copper wiring clamping plate (1) (4) that bolt (2) is fixed on the porcelain plate two ends, different is that the wiring clamping plate (4) that can be connected with the equipment conducting rod are that an internal diameter has screw thread (10), one side has the copper pipe (13) that internal diameter is regulated opening (11), and a tinning transition zone (6) (8) (9) can all be connected with the contact position of aluminium safety plate on the gusset piece (5) of inboard and two wiring clamping plate (1) that wiring clamping plate (1) can contacts with aluminum conductor and (4) and porcelain plate (3) and (7).
The goat's horn protector that adopts such scheme to make, equipment connects closely with conducting rod, and contact area is big, and has copper-aluminium transition performance preferably, has avoided the shortcoming of existing product.
Introduce a kind of embodiment below in conjunction with accompanying drawing.
Fig. 1 is the front view of present embodiment, and Fig. 2 is the sectional drawing of one terminated line clamping plate (1), and Fig. 3 is the end view of its other end wiring clamping plate (4).
As shown in the figure, this goat's horn protector also is that wiring clamping plate (1) and (4) by porcelain plate (3) and two ends are formed by connecting through bolt (2).Wherein, wiring clamping plate (4) are that the copper pipe (13) and the gusset piece (7) of threaded in (10) constitutes, the screw thread of this wiring clamping plate (4) internal diameter and the threads engaged on the equipment conducting rod, after the assembling, tighten internal diameter by fastening bolt (12) again and regulate opening (11), conducting rod and wiring clamping plate (4) large tracts of land are combined closely, like this, just can avoid the problem of current-carrying area deficiency.In addition, on connecting plate (5) (7) and the inboard of wiring clamping plate (1) all be provided with a tinning transition zone (6) (8) (9), with when aluminum conductor or aluminium matter safety plate combine, can avoid producing the phenomenon of couple corrosion.
Claims (1)
1, the fixed goat's horn protector of a kind of screw thread, constituted by porcelain plate (3) with the copper terminal block (1) (4) that bolt (2) is connected in two ends, it is characterized in that: the wiring clamping plate (4) that can be connected with the equipment conducting rod are that an internal diameter has screw thread (10) one sides to have the copper pipe (13) that internal diameter is regulated opening (11), wiring clamping plate (1) can with the tinning transition zone (6) (8) (9) that can all be connected with the contact position of aluminium safety plate on the connecting plate (5) of the contacted inboard of aluminum conductor and wiring clamping plate (1) (4) and porcelain plate (3) and (7).
