Description

Distribution transformer outlet connection clamp

technical field

The utility model relates to a connection clamp for outlet wires of distribution transformers.

Background technique

At present, the output wire connection of the transformer is to use nuts to fasten the output wire on the screw terminal of the transformer. This connection method has the following problems. When the output load of the transformer is too large, due to the small contact area between the transformer terminal and the output line, in addition, factors such as looseness will occur after long-term use, which will cause the connection part of the transformer terminal to heat up, oxidize, The vicious cycle of poor contact will lead to overheating and fuse wires, causing power outages and causing unnecessary losses to power users.

Utility model content

The purpose of the utility model is to provide a distribution transformer outlet connection clip which increases the contact area, has firm wiring, and avoids overheating and fusing the wiring.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a distribution transformer outlet connection clamp, including a conductive connection plate. One side of the conductive connection plate is provided with an open fastening screw sleeve for threaded connection with the transformer outlet terminal, the closed side of the open fastening screw sleeve is integrated with the conductive connection plate, and the open sides of the open fastening screw sleeve are respectively An upper fastening plate and a lower fastening plate for fastening the opening fastening screw sleeve are connected, and the upper fastening plate and the lower fastening plate are fastened by fastening bolts. The conductive connection plate is provided with screw holes, and the screw holes are provided with fixing bolts for connecting the lugs.

The beneficial effect of the utility model is that: one side of the conductive connection plate is provided with an open fastening screw sleeve for threaded connection with the transformer outlet terminal, and fastened by the upper fastening plate and the lower fastening plate. It can greatly increase the contact area between the open fastening screw sleeve and the threaded connection of the transformer outlet terminal, thereby avoiding the fuse of the wire and burning of the terminal due to excessive current, thereby avoiding the loss of power failure, reducing maintenance and increasing the reliability of power supply. The utility model adopts the open fastening screw sleeve to be pressed and connected to the outlet terminal of the transformer, which can effectively prevent the insulating sleeve from being stressed and causing oil leakage when the nut is forcibly tightened.

The utility model has the advantages of simple structure, firm screw connection with the transformer outlet terminal, and is not easy to fuse.

Other advantages, objectives and features of the present utility model will be set forth in the following description to some extent, and to some extent, based on the investigation and research below, it will be obvious to those skilled in the art, or can be Get teaching from the practice of the utility model. The objectives and other advantages of the utility model can be realized and obtained by the structure particularly pointed out in the following description, claims, and accompanying drawings.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

Detailed ways

As shown in Figure 1, a distribution transformer outlet connection clamp includes a conductive connection plate 3, one side of the conductive connection plate is provided with an opening fastening nut 4 for threaded connection with the transformer outlet terminal 5, the opening The closed side of the fastening nut is integrated with the conductive connecting plate, and the open side of the open fastening nut is respectively connected with an upper fastening plate 7 and a lower fastening plate 6 for fastening the open fastening nut. The plate 7 and the lower fastening plate 6 are fastened by fastening bolts 8; the conductive connecting plate 3 is provided with a screw hole, and a fixing bolt 2 for connecting a lug is provided in the screw hole.

When in use, first thread the open fastening screw sleeve 4 on the transformer outlet terminal 5, and clamp and fix the upper fastening plate 7 and the lower fastening plate 6 with fastening bolts 8, and then connect the terminal lug 1 to the outgoing wire , Fix the lug 1 with the fixing bolt 2.

Because the opening fastening screw sleeve 4 is threadedly connected with the transformer outlet terminal 5, the contact area of the connection is increased, and the fastening effect of the upper fastening plate 7 and the lower fastening plate 6 makes the transformer outlet connection firm and not easy to generate heat. In order to ensure the normal power supply and avoid power failure losses.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model without limitation, other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the utility model, as long as they do not depart from the technical solution of the utility model The spirit and scope should be included in the claims of the present utility model.
