The technical field is as follows:
the utility model relates to a novel low pressure outlet head and flexible coupling's integrated configuration of being qualified for next round of competitions belongs to the transformer field of making.
Background art:
for a long time, the low-voltage connector lug and the outgoing line flexible connection of the oil-immersed transformer are processed separately, outgoing line flexible connections with corresponding sections are configured according to connector lugs with different specifications, and are assembled and fastened through bolts when in use (the structure is shown in figure 3). The structure has strong universality and can be configured in different combinations according to requirements.
Along with the advancement of national urbanization construction, the population density of cities is gradually increased. Meanwhile, along with the improvement of the living standard of people, the household power load is also increased synchronously. This determines the development direction of miniaturization and large capacity of the current box transformer products. The transformer is the most important electrical element in the box transformer product, and the volume of the transformer basically determines the external dimension of the box transformer, so that manufacturers of the transformers carry out miniaturization design to the best extent. Under the background, the original transformer low-voltage connector lug and the outgoing line flexible connection are separately processed, and then the outgoing line mode of bolt connection needs a lot of installation space due to larger volume, so that the requirement of technical progress of box transformer products cannot be met.
The invention content is as follows:
the utility model provides a novel low pressure lead head and flexible coupling's integrated structure of being qualified for next round of competitions, this structure is with the staple bolt position extension that low pressure connector lug and conducting rod installation are fixed, and the intermediate junction mounting groove that opens is then qualified for the next round of competitions soft coupling and is embedded the installation notch the inside, fills with phosphorus copper welding liquid again, guarantees mechanical strength and electric conductive property. The novel structure cancels the mode that the low-voltage connector lug and the outgoing line flexible connection are connected through bolts in the original structure, and integrates the low-voltage outgoing line lug and the outgoing line flexible connection into a whole.
The utility model discloses the technical scheme who adopts has: the utility model provides a novel low pressure outlet terminal and flexible coupling's integrated configuration that is qualified for next round of competitions, includes the low pressure outlet terminal and is qualified for the next round of competitions the flexible coupling, the low pressure outlet terminal is the staple bolt structure, is equipped with locking hole and bolt fastening hole on the low pressure outlet terminal, locking hole and bolt fastening hole mutually perpendicular are equipped with the mounting groove on the outer wall of low pressure outlet terminal, the mounting groove sets up along the axis direction of bolt fastening hole, and the flexible coupling level of being qualified for the next round of competitions is placed, and the one end of the flexible coupling of being qualified for the next round of competitions pegs graft in the mounting groove, and it.
Furthermore, the outlet flexible connection is of a strip structure, and an arc part is arranged on the outlet flexible connection.
Further, the mounting groove is of a rectangular structure.
The utility model discloses following beneficial effect has:
the utility model has compact structure, greatly reduces the requirement of the transformer low-voltage outgoing line on the assembly space, directly reduces the overall dimension of the box transformer substation, and reduces the occupied area of the box transformer substation by more than 5 percent; the installation contact surface is reduced, the connector lug and the flexible connection are integrally designed, and the reliability of the product is improved through welding combination; the safety transfer process is reduced, and the production efficiency is improved; the new structure greatly simplifies the product structure, reduces the material usage, reduces the average weight by about 15 percent, saves raw materials and meets the production requirement.
Description of the drawings:
fig. 1 is a front view of the present invention.
Fig. 2 is a top view of the present invention.
Fig. 3 is a mounting structure for soft connection between a low-voltage outlet terminal and an outlet wire in the prior art.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
As fig. 1 and fig. 2, the utility model relates to a novel low pressure leading-out terminal and flexible coupling's integrated configuration of being qualified for next round of competitions, including low pressure leading-out terminal 1 and flexible coupling 2 of being qualified for the next round of competitions, low pressure leading-out terminal 1 is the staple bolt structure, be equipped with locking hole 11 and bolt fastening hole 12 on low pressure leading-out terminal 1, locking hole 11 and bolt fastening hole 12 mutually perpendicular, be equipped with mounting groove 13 on low pressure leading-out terminal 1's outer wall, mounting groove 13 is rectangle column structure, mounting groove 13 sets up along the axis direction of bolt fastening hole 12, flexible coupling 2 levels of being qualified for the next round of competitions are placed, and flexible coupling 2's the one end of being qualified for the next round of competitions is pegged graft.
The utility model provides a flexible coupling 2 of being qualified for the next round of competitions is the strip structure, is equipped with circular arc portion 21 on flexible coupling 2 of being qualified for the next round of competitions.
The utility model discloses the structure is with the staple bolt position extension that low pressure connector lug and conducting rod installation are fixed, and the middle mounting groove that opens is then qualified for the next round of competitions the flexible coupling and imbeds installation notch the inside, and it is tamped with phosphorus copper welding liquid again, guarantees mechanical strength and electric conductive property.
