Abstract
The utility model relates to a special wire clamp for a transformer. The utility model is characterized in that the outer sides of an upper and a lower clamping plates with corresponding concave surfaces are tightly fixed by U-shaped screws, and the bottom of the lower clamping plate is provided with a guide rod sleeve having inner threads. The guide rod of the transformer is screwed with the guide rod of the wire clamp via the utility model, and a wire leading clamp is arranged in the wire clamp. The problem of oil seepage due to the loose guide rod caused by original leading wire directly connected with the guide rod is solved, and simultaneously the contact surface of an electric contact is enlarged to solve the problem of oil seepage caused by an aged sealing rubber gasket due to heating.
Description
The utility model relates to the special-purpose wire clamp that transformer is connected with power supply lead wire.
Transformer is connected by the power supply lead wire of the wiring guide rod on its housing with the outside, and general lead-in wire is on guide rod, fixes by the nut on the guide rod.The shortcoming of this syndeton is that during clamp nut, guide rod also and then changes sometimes, be afraid of to cause internal short-circuit, also guide rod will be gone back to, in the rotation process of guide rod again, the oil immersion that makes transformer inside has destroyed the sealing at guide rod place thus to guide rod, produce oil impregnate.Contact-making surface owing to guide rod and lead-in wire is little in addition, and when electric current was excessive, guide rod was heated, and the seal gasket of guide rod is heated thereupon, thereby has quickened the aging of this rubber cushion, sealing property is reduced, and produce oil impregnate.
The purpose of this utility model is: provide a kind of transformer special-purpose wire clamp, when the guide rod of transformer connection is connected by this wire clamp with outside lead, guide rod is not stressed, do not rotate, the contact-making surface of electric contact is big, thus the peripheral oil impregnate problem of suitable guide rod when solving guide rod and directly being connected with lead-in wire.
The technical solution of the utility model is: the special-purpose wire clamp of a kind of transformer, upper and lower clamping plate with line ball, it is characterized in that: the obverse of upper and lower clamping plate is concave surfaces, the both sides of train wheel bridge are provided with the post hole, the bottom surface of lower plate is provided with leader casing, the U-shaped screw is contained in the outside of lower plate, and U-shaped screw two ends cooperate with nut respectively by the post hole of train wheel bridge.
During use, in the concave surface of cable guide between upper and lower clamping plate, the nut on the fastening U-shaped screw compresses upper and lower clamping plate and fully contacts and fix with lead-in wire, and the wiring guide rod on the leader casing of lower plate bottom surface and the transformer is for being threaded.
The advantage of present technique is, guide rod and wire clamp are for being threaded, and wire clamp is fastenedly connected by nut with lead-in wire, has changed the method that directly tightens lead-in wire in the past at guide rod, and therefore, guide rod is stressed little, has solved guide rod periphery oil impregnate problem in the past.At least 3 times of the contact-making surface increases of electric contact can prolong useful life of sealing gasket.
Below in conjunction with description of drawings embodiment of the present utility model.
Fig. 1 is the structural representation that the special-purpose wire clamp of the utility model transformer is connected with lead-in wire.
Fig. 2 is the end view of the utility model Fig. 1.
Among the figure, the opposite face of train wheel bridge (10) and lower plate (11) has concave surface respectively, there is post hole (3) both sides of train wheel bridge (10), the bottom surface of lower plate (11) is provided with tapped leader casing (1), U-shaped screw (2) is holding in the palm lower plate (11), the post hole (3) that train wheel bridge (10) is passed at the two ends of U-shaped screw cooperates with nut (6), (7), pad (4), (5), (8), (9) are arranged between nut and train wheel bridge, during work, lead-in wire (12) is clipped among the concave surface of upper and lower clamping plate, and is fastening by nut (6), (7).The internal thread of leader casing (1) is threaded with the guide rod of transformer.
